SOCKET
RESEARCH SECTION - (Edison No. 1 & 2 Sockets)
|
THIS PAGE WAS
CONTINUED FROM HERE
http://www.antiquesockets.com/bergmann1.html
The
Edison No. 1 - Version A, B, & C Sockets
|
The
Edison No. 1 socket is basically any socket configuration that uses
baseless bulbs and before the invention of the screw base.
The first Edison sockets in 1879 and until late 1880 were wooden
sockets that did not yet have the Edison screw base for the bulb.
The oldest bulbs had wires sticking out of the end, which were normally
folded under or slipped between two metal tabs. These tabs were
then held by winding thread around the top of the tabs, which held
them tight against the base of the bulb.
These tabs were made from two different materials being either German
silver or brass. The tabs on the bulb, would then press against
similar tabs inside of the wood socket opening as shown in the picture
on your right.
Within a short time (mid 1880), wooden peg type adapters were invented.
These adapters were carved out of wood and included metal tabs on
the sides of the peg part of the adapter, which fit into the socket.
The other end had a hole that the bulb fit into. This adapter provided
a much more solid connection for the bulb when pressed into the
socket as shown below.
These No. 1 Edison sockets could only be used with the bulb facing
upward, as they would easily fall out of the socket if positioned
straight down.

In
1879/1880, the No. 1 sockets were sometimes used with a standard
telegraph switch (as shown on your right) to turn it off and on,
though it included the earliest thumb screw type of switch on the
side of the socket (as shown on your left). Note that these thumb
screw knobs were made of brass as it is hard to tell from the photos.
Later in late 1880, a new snap switch was invented and installed
on to the side of the no. 2 socket which was reminisced as invented
with a second (soon to be held) Edison demonstration in mind.
An improvement with the 1-B was made in which the wires no longer
connect to the outside of the socket (as seen on the pictures of
the 1-A above), but now come down through the bottom hole like you
are used to seeing on sockets even today. This was not the case
on the No. 1-A version (shown clearly in the picture on your right),
even though when simply looking at it and seeing the hole on the
bottom and thinking that the wires would come down through it. The
wires were connected on the outside to the terminal screws shown
above on the sides of the socket and the hole on the bottom was
simply to connect it to a fixture with the wires connecting from
the outside of the socket.
The No 1-A socket is socket is documented as being in use at the
December 31st 1879 Menlo Park demonstration. The No. 1-B version
is the socket that is shown in the later patent that was applied
for on February 5th 1880 and approved on October 3rd 1882. It was
assigned patent no. 265,311.
The number 1-A pictures have been provided by Adam Allerhand (a
moderator in our forums),
and the 1880's Bergmann telegraph key is part of my collection.
|
The
Edison No. 1-C Socket
|
I
have two sources that document the Edison No. 1-C socket and so
far examples of two possible different configurations of it which
are shown below. Please note that the second example has not yet
been documented as actually existing in real life. The first and
top socket picture below came from an ebay auction from many years
ago. The second socket picture (shown below on the bottom) came
from photos taken by Tim Tromp of the Dr. Hugh Hicks collection
back in 1999. (Tim Tromp is the owner of Kilokat's
Antique Light Bulb Site

This
No. 1-C sockets have a new design in the thumb screw switch and
now a more ornate knob which is different from the earlier 1-A and
1-B sockets. This is easy to compare from the photo's above (in
the 1-A section) to the sockets shown directly above and the drawing
shown below (example clips on the right).
Also, from the Edison drawing above and the Kruesi drawing below,
we get a new possible configuration (one with a hole on the side),
and two examples of how it would have been mounted to fixtures.
Also shown below, is a possible variation in design. Notice that
in the Kruesi drawing on the right side (shown below) that the shell
more resembles the flowing or indented grooved design that we are
used to seeing in the Edison No. 1-A and B socket versions. There
are no documented examples of this version of the No. 1-C socket
existing in real life. It could have just been Kruesi's concept
of what it would look like, but then manufactured as the real life
examples we now have.
The
Edison No. 2 - First Screw Shell & First Snap Switch
|
After
the Menlo Park demonstration of December 31st 1879, Edison started
getting ready for the next demonstration. The first improvements to
be addressed was how the bulb attached to the socket; and how the
socket switched off and on. Keeping in mind that the first (No 1)
sockets could only be used in an upright position, Edison knew that
this was the first improvement that he needed to make in the socket.
In his new patent application he first gives the application number
for the old socket filed by him, he then goes on to say: "In
such the lamp is held to the socket by friction between the neck of
the lamp and the socket. It is desirable, however ...to hang the lamp
from the socket or to support the lamp horizontally." This
No. 2 "Screw Shell" socket, was applied for patent on March
26th 1881 and approved on December 27 1881 and was assigned patent
No. 251,554.
Even though the patent was applied for late, it can be documented
as being used in late 1880. This is what also makes it important to
note this design patent from 1880 which was for a bulb that could
only be used in this socket. It was applied for on November 30th 1880
and assigned design patent no. D12,631.
DATING
THE NO. 2 EDISON SOCKET
I must admit that this has been one of the hardest sockets to put
a date on, as it was not well documented in history. This is likely
due to the fact that it only lived a very short time. The late patent
dates do not help in this matter either since they were filed after
it was already in use for some time.
We already dated it to Nov. 30th 1880 by proving that a bulb existed
at that time (but in the strict purest sense, this is not the socket).
There is not doubt
to the No. 2 being an 1880 socket, but how close can we date it by
digging for different kinds of documentation?
Francis Jehl 'reminisced'
about this socket in when telling the story: "When
preparations for the second exhibition got underway, Edison took up
the subject of socket and lamp base again. He knew these must be constructed
so that the lamp could be held securely in any position, and at the
same time furnish a good electrical connection." "One night
in the early part of 1880, while the master was talking on the subject
to some of his assistants, he noticed a kerosene oilcan standing near.
Taking it up and unscrewing its cover, he studied the combination
for a while and then exclaimed, 'This most certainly can make a bang-up
socket for the lamp, as well as a base!' Thus the Edison screw socket
and lamp base of 1880 were born." (Menlo
Park Reminiscences vol. 2 pages 740-741)
From researching through the Menlo Park notebooks, technical scrapbooks,
documents, etc., I found that the bulb to socket attachment method
was the attention on many drawings during early 1880 to late 1891.
I should also mention that I could not find any reference to it being
called a "Bang-up" socket, but several references to it
being the "Screw Shell". I looked for this because I had
found a collector referring to this socket as the "Bang-up"
socket. So far, I count this "title" as an undocumented
reminisced name for the socket and will simply call it the No. 2 Edison
Screw Shell socket on this site (unless future documentation surfaces).

Early
Fixtures Documented Using Edison No. 2 Sockets
|
EARLY
FIXTURES Documented Using No. 2 Sockets
The engraving of the chandelier shown above was taken from a series
of Menlo Park scrap books archived by the Edison Lamp Company. The
scrapbooks are documented as the Charles Batchelor Scrapbook Collection
Batchelor was one of Edison's closest laboratory assistants and business
partners. This chandelier engraving was found in the 1878-1881 scrapbook
volume, originating from a Scientific American magazine article that
was hand dated Jan. 22 1881. Charles Batchelor (shown in the picture
on the right) also signed and witnessed most of the drawings in the
1880 Menlo Park technical notebook no. 60 (talked about on this web
page and found in the sections directly below). The Scientific
American Vol.
XLIV. No. 4 of January 22, 1881 as well as the article as archived
in the Charles
Batchelor scrapbook has been linked here
along with some close up photos taken by Adam Allerhand.
In
the Menlo Park technical notebooks almost two entire volumes* are
taken up with drawings of a project which included chandeliers, hall
lights and wall brackets, as well as the parts needed to be manufactured
and used on them (such
as holders, sockets, etc.)
As seen in these notebooks, Edison conceived and designed most of
the technicals such as motors and regulators, E.H Johnson (under
Edison's direction) the final sockets and John Ott (Edison's
principal model and instrument maker) was the person that manufactured
and assembled most of the chandelier parts (including the sockets).
*(these two volumes are 1880-1881-Menlo-Notebook-No-153-Sept-to-Feb
& 1880-Menlo-Notebook-No-60-Oct-to-Nov)
The
chandelier sections appear to have been completed
mid November of 1880. It is also noteworthy that this chandelier
project (as being seen in the notebooks), appears to have been a work
in progress for the entire system (which would not be complete until
every part in the system that was needed to make it work, were also
completed). These two notebooks document the making and design of
a regulated motor, sockets, switches, proper wire to be used from
many samples requested, etc.. They also document designs for the making
and wiring of what appears to be a matched set consisting of chandeliers,
wall brackets and hall lights that have the fixture wire running inside
the tubing (and not wrapped around the outside of the fixtures as
in the old converted gas fixtures of which there were many of in those
days).
It is noteworthy that several illustrations shown for the chandelier
wiring, matches the chandelier shown above in the Scientific
American article. An example of this is
shown in the illustration shown below. This illustration is only one
out of many that show wiring for a chandelier from arm to arm, socket
to socket, chandelier to switch, lighting to dynamo, etc.

Since on the topic, it is also noteworthy that the design for the
chandelier matches the Hall Light design shown in the Menlo Park Notebook
illustration shown below. It uses the same square tubing coming down
at the same angle as shown in the illustration. While this is not
proof positive that this chandelier shown in the Scientific
American is the same being constructed
in this Edison lighting ensemble, it does provide strong circumstantial
evidence together with dating.

As shown below, the Mitchell Vance chandelier company was consulted
on shaping machines needed for the ornamental work on the new chandeliers,
which explains the obvious Mitchell Vance shape and design at the
top and how the supporting bars meet together on the chandelier arms.
Also note that shaping machines would not have been needed for gas
conversions. These were newly designed chandeliers being made from
scratch.
EARLY GAS TO ELECTRIC CONVERSIONS
Around
this time in history, there are also some documented gas fixtures
that had been converted to electric. One of these has been talked
about in many publications as hanging in the private residence of
Francis R. Upton.
"The
chandelier that Upton had in his private residence near the railway
station at Menlo Park was fitted with these new type sockets having
snap keys. Often the distinguished visitors who came to the laboratory
inspected the lights and sockets at Upton's house. The lamps in the
Upton chandelier were all placed in an inverted position in contrast
with those used in the first sockets." (Menlo
Park Reminiscences vol. 2 page 742)
Francis Arthur
Jones was the author of a book called Thomas Alva Edison published
in 1908
In the Jones book we get a bit more detail:
| "The
first electrolier was wired and placed in service some time
during 1880, at the residence of Mr. Francis R. Upton, at Menlo
Park, near Edison's laboratory. Great care was taken to distinguish
the polarity of each conductor, the positive wires being of
red and the negative wires of blue flexible cord. The lamps
were from the first placed in an inverted position, which is
now so familiar but was then so novel. This electrolier was
shown at the St. Louis Exposition in 1904." (Thomas
Alva Edison By Francis Arthur Jones - page 121) |
The Electrical Engineer published an article about this same chandelier
entitled "The First Incandescent Chandelier" on August
12th, 1891 Vol.12
Page No. 155 (broken link)
The
Francis Upton Chandelier Dilemma
I should mention that there is some confusion in my mind about what
is being called "The Upton Chandelier" as well
as the reference to it being the "First" chandelier.
Also, what this was actually meant to mean, as seen in the
original 1891 Electrical Engineer article (broken link). We need to first
pay close attention to the article itself, since the statements
shown above (as well as in other books and publications) are most
obviously plagiarized and not "direct quotes" from it.
Since some statements found in publications have been made without
quoting the source, statements have been made that have been interpreted
improperly or hyped in the wrong direction. This now causes there
to exist multiple sources seeming to tell the same basic story.
Remember that each time it is copied by a new source, it is slightly
changed by using add-lib in different directions - which have been
made up from their own understanding of their particular individual
plagiarized source. If this questionable story originally found
in this Electrical Engineer article, is reused over and over again
(from what ever version down the tree) without being directly quoted,
soon it will be even worse then it is now.
Adam Allerhand put together an excellent color
coded comparison chart (broken link) that helps to quickly point out the obvious
plagiarism.

It
would be important to note that the other chandelier shown in this
section (from the Scientific
American), is a 'true first' (being documented)
in the sense that the fixture wires run through the inside of the
tubing and was designed from the start as an "Electric"
chandelier. It was not an existing gas chandelier that had been
converted to electric. Please do not misunderstand me, I am not
saying the the Scientific
American was "without a doubt" the first;
But what I am saying, is that this one shown in the Electrical Engineer
article (the Stieringer/Upton), truly does not directly qualify
for this status.
The photo shown on your right, was taken by Tim Tromp (the owner
of Kilokat's Antique Light Bulb
Site) at the Henry Ford Museum. You can view a few more
high resolution pictures with close up pictures of the sockets and
cross arms in this
pdf (broken link).
WHY IT CAN'T BE THE "FIRST"
Let
me explain: First, you need to take into consideration the original
source of the information, which was given to the Electrical Engineer
by the new owner of it (Luther Stieringer) who was a big "collector"
of Edison relics. Many times with collectors, stories are invented,
stretched or simply misrepresented to enhance what they own (or
to put it more simply and truthfully - what they don't own). Second,
the fact that there were other gas chandeliers in history that were
converted to electric is documented fact. There were many such chandeliers
and gas fixtures that had been wired for electric. In the December
31st 1879 Edison demonstration Edison had taken two of his gas chandeliers
and wired them with No. 1-A sockets pointing straight up. Upton
also speaks of a chandelier in a personal letter to his father dated
Dec. 28th 1879 - "I had a number of gentlemen in my parlor
among them the correspondent of the London times. He made a note
of my chandelier" (this was not the one with these No.
2 sockets). There is also another in Menlo Park technical notes
from Upton while documenting filaments in his January 2, 1880 entry
"217. Burnt 4 days. Chandelier over Griff.s desk. Broke
1/4 inch above regular place, probably bad vacuum. Edison brought
this to me."
In the Electrical Engineer article it says "The chandelier
of which an illustration is shown on this page is one of the most
interesting relics of the early days of incandescent lighting. It
is, in a word, the first chandelier ever used for the specific purpose
of carrying incandescent lamps."
Not true, but it was possibly the first converted gas chandelier
to have the sockets turned in the downward position.
In
the Jehl book there is a picture of a four socket chandelier
in Vol. one on page 409 shown on your right, in which he says
about it:
"First chandelier fitted with electric lamps. It was
a gas fixture equipped with the earliest type of sockets and
thumb screw switches."
Now, while this looks like it could be "The First Chandelier",
you do not need to be a rocket scientist to know that they
both can't be.
At least Jehl's has the "FIRST" sockets on it :-)
The chandelier shown here was a gas chandelier made by Mitchell
Vance starting with their 1870 catalog in which it was shown
on plate No. 7 as shown below.
Because of the sockets used, It would have been converted
to electric some time early possibly during or right after
1879.
I have also included a real life picture of one of these 'first'
converted gas fixtures (shown below). It is also easy to see
from the picture, that it is a second example and not the
exact same fixture of Jehl's illustration. |

One could also assume that the Stieringer/Upton chandelier was the
one that Upton owned and spoke of in his letter of December 28th
1879 which might predate these other converted ones; And then at
a later date it was converted again with the new sockets pointing
downward in late 1880. But, the problem with this thinking would
be; that the picture shown of the Stieringer chandelier was not
offered by Mitchell Vance during that time. I am not a Mitchell
Vance expert, but I have catalogs to see different styles and parts
were being manufactured and used on M.V. chandeliers to compare
for dating: 1870, 1871, 1876, 1879, 1880, 1882, 1883, 1887. Some
of these parts (on the Stieringer) do not show up at all in the
1880 catalog but do in the 1882 catalog (such as the obvious canopy
style). So, assuming that parts were first made; and the time that
it would take to produce the new lines; and have them in the catalog
for the next year; to be right on target with the statement In the
article which says "This fixture was purchased from Mitchell,
Vance & Co. originally, and then wired on the spot",
and not something that was hanging around for years and converted
again.
The point of this being that this Stieringer 'gas conversion' most
defiantly was not;
"in a word, the first chandelier ever used for the specific
purpose of carrying incandescent lamps"
As reported by the Scientific
American with their source being Luther Stieringer.
OR ""the first electrolier wired for incandescent electric
lighting" as reported in the book Edisonia in 1904 with their
source being obvious plagiarism (broken link).
OR "the first electrolier was wired and placed in service"
as reported in the book by Francis Arthur Jones in 1908 with their
source being obvious plagiarism (broken link).
My closings on the chandelier topic, would be that if any chandelier
was to be called the first "electric" chandelier (used
for the specific purpose of carrying incandescent lamps), it
would need to be like shown in the Scientific
American magazine article dated Jan. 22 1881 (with the wires
concealed inside of the tubing). Also, keeping in mind the dating
of early 1881; and the information and style of the chandeliers
and other parts in the Menlo Park notebooks; this chandelier
shown in the Scientific
American would qualify as being the first real electric
chandelier. There is however NO DOCUMENTATION to positively confirm
this at this time as it is all circumstantial evidence. It is simply
the first real type chandelier that I have found documented with
no information as to where it was used or how many of them made.

Other
Dating Methods For The Edison No. 2 Socket
|
ANOTHER
DATING METHOD For The No. 2 Edison Socket
So far
I believe we have enough to document these sockets into 1880, but
after exhausting myself looking for the socket to be pictured or
documented other ways in 1880, I changed my approach and thought
along another line.
I remembered that this was a short lived socket, that had been replaced
early on with the Edison No. 3 (Johnson's bevel ring socket). If
I could find when work on the new socket started, this could possibly
also date us into 1880 for the no. 2 socket. This would be because
the first would have had to already exist, before starting work
on a new one.
Francis Jehl 'reminiscences' ...
| "Toward
December of 1880 Edison remarked casually one day that it would
be better if the metal ring at the bottom of the lamp base were
given the form of a cap. The change in the form of the socket
and lamp base came about in this manner... Johnson took out
a patent for a bevel ring instead of the straight one shown
in Edison's patent...Sockets that were sold in 1881, in fact
the first ones, were fitted out with the Edison screw shell
and the Johnson bevel ring" (Menlo
Park Reminiscences vol. 2 pages 743-745) |
So, if Jehl is
correct with his date, we can also use this method to document this
socket into late 1880.
After searching, I found that Jehl was correct as to the date above.
As far as I could document, Johnson was already starting work on his
socket in early in September of 1880, which would be 'toward' December
of 1880 as Jehl had claimed. (I will cover the Johnson documentation
for No. 3 in the next socket section).
