John Eng's Dead Tech Rescue

Electromechanical

Transceivers

Born out of the 19th century with the invention of the telegraph by Samuel F Morse, these items use a combination of electricity and mechanical devices to send and receive information. Telephony invented by Alexander Graham Bell allowed voice reception and transmission to be sent over wires great distances through relay stations using electromechanical repeaters until the invention of the vacuum tube by Lee De Forest in the 20th century. Bell's discovery led to the foundation of one of the largest and most powerful corporations in history the American Telephone and Telegraph (AT and T) Company.

Compact Local Battery Wall TelephoneMonarch Telephone Mfg CoFort Dodge, IA and Chicago IL

In 1926 Automatic Electric (Gary Group) acquires both American Electric and Monarch Telephone to make non dial telephones.

This is their compact version in solid red oak. there is no lightning arrester, and the box is about 2/3 the size of the full size models with wet cell battery box.

The note taking board is secured by two arms. Notice the shorter transmitter arm. Access to the inside require loosening two screws on the right. Some models have reverse opening.

ABOVE: I have seen a lot of these magneto phones interchange parts, so many times it is hard to ID the original maker. This particular example has a Stromberg-Carlson 4 bar magneto. I don't see many 4 bar units. Most I have seen are 5 bar. The bottom compartment is for the No 6 Dry cells connected in series. BELOW: The Stromberg-Carlson 4 bar magneto, the hook switch and retarding coil.

ABOUT

Automatic Electric Company

In 1889, a Kansas City resident named Almon B. Strowger invented an automatic telephone switch. In 1891, Joseph B. Harris of Chicago convinced Strowger to move to Chicago, and the Strowger Automatic Telephone Exchange was established. In 1901, the company changed its name to Automatic Electric. In 1919, Automatic Electric was purchased by Theodore Gary & Co., a Kansas City–based enterprise that already owned several small telephone companies around the country. In 1955, when Theodore Gary & Co. was acquired by the General Telephone Corp. (renamed the General Telephone & Electronics Corp., or GT&E, in 1959), Automatic Electric became a subsidiary of the nation's second-largest telephone company, which was headquartered in New York.

Automatic Electric IA (Monophone) One of their first combined receiver-transmmitter dial phone by Automatic Electric. Their early departure from the candlestick phone. Like the Western Electric 102 / 202 a subset is required for ringer and anti sidetone.

Kellogg provided these phones well after WW2, since many communities were still served by the smaller phone networks.

ABOUT

KELLOGG SWITCHBOARD & SUPPLY CO

Milo G. Kellogg, an electrical engineer, founded the company in 1897 in Chicago. Kellogg had become the undisputed master of the switchboard. He’d helped countless independent operators obtain quality, long-lasting phone systems, particularly in small towns outside the iron grip of Bell. These efforts only increased when many of Bell’s original telephone patents began expiring in 1893. Soon after the technology sharing agreement was announced in 1951, Kellogg was acquired by ITT.

Kellogg Grabaphone with F111 Base. (1905-1925) Kellogg Switchboard and Supply Co Chicago IL: Kellogg was the first to mass produce a receiver-transmitter as one unit later called the "handset". The Grabaphone refers to the handset which could be mated with a variety of bases. The handset was designed to minimize side tone between the receiver and transmitter. Wth the early technolgy elaborated means were used to minimize side tone which meant sacificing some reproduction and transmitting voice quality.

The phone like all Kellogg products were offered in many versions for small and private networks. This wouild be Kellogg's last company designed phone. By the 1950's most manufacturers adopted the the Western Electric design due to the government lawsuit on ATandT antitrust case.

Kellogg K500

1954-55 The end of an era. There is an agreement that phone technology needs to be shared for the benefit of users and security ending proprietary phone designs. AT&T was ordered to share patents with other phone makers.

Kellogg K500 (1954-1956) Kellogg Switchboard and Supply now a division of International Telephone and Telegraph (ITT), produced the K500, a near twin of the Western Electric 500. The main differences were in the outer cover and handset. By 1957 Kellogg / ITT phones were basically identical to the WE 500 phones as well as parts interchangeability

The internals are very similar to Western Electric. In fact the parts were interchangeable. The appearance of the handset was similar to the Masterphone 1000.

Stromberg Carlson Telephones

1954-1960s

Combined Phones for Small and Local Area Networks

ABOUT

Stromberg Carlson

Founded by Swedish natives Alfred Stromberg and Androv Carlson in 1894, the year Alexander Graham Bell's patent expired, the company was one of the largest suppliers to independent (non-Bell) telephone companies. In the mid-1900s, Stromberg expanded to also manufacture radios and TVs before its acquisition by General Dynamics in 1955.

Stromberg Carlson 1543

Stromberg Carlson: Model 1543 (1955-1970) a redesigned 1443 phone.This was their telephone after the technology sharing decision in the 1950s. Stromberg Carlson has their own design but was still pretty similar to the technology of the Western Electric 500 design. Eventually the phones became identical in appearance and design.

ABOVE: Stromberg Carlson 210558 Network which is similar to Western Electric 101A Network in the 302 phone. BELOW: Dialer mechanism.

Stromberg Carlson 1243

Stromberg Carlson: Model 1243 (1946-1955) a redesigned 1222 phone (1936-1946)This was their telephone to compete against the Western Electric 302. The 1222 was introduced in 1936 and upgraded to the 1243 in 1946. The development of their 210558 Network made it competitive

ABOVE: Stromberg Carlson (SC)1243 with dial mechanism made by them. It had a broken spring so it was replaced with a refurbished AE dialer which fits perfectly (RIGHT)>. AE did make dialer for many SC telephones.

************************************

SHOWCASE:

Making a 40 Hz ringer into a 20 Hz ringer for a Stromberg Carlson 1543 phone.

ABOVE: Thie ringer is this phone is 73C-40, meaning the ring frequency is 40 Hz.
BELOW: A quality audio oscillator like the vintage HP 200CD works great for checking ringer frequencies.

It seems that it was very common for Stromberg Carlson 1543's to be used in party lines or private exchanges. It is very difficult to get one with a 20Hz ringer which is standard as party lines and private exchanges are no longer around. Unfortunately, party line ringers will not ring on the current LAN line.

BRIEF HOW IT WORKS: Most post war ringers consist of the ringer coil connected in series to a capacitor. The coil and capacitor have AC resistance or IMPEDANCE. When the frequency goes up the coil AC resistance goes up while the capacitor's goes down. At the correct frequency they cancel each out, permitting maximum current through the ringer for it to ring strongest. That point is the resonant frequency and provides efficient use of power in LAN line telephone operation. Different ringer frequency provides more subscribers to use a single line as their phone will ring at a particular frequency, hence the use of a "party line" and is a cost savings to the phone company.

Conversion from 40 Hz to 20 Hz ringer.
A. An audio generator will serve as a source of ringer frequency to check the ringer circuit.
B. If possible the ringer flapper closer to the coil pole, but still allow flapper to move freely. This will increase the sensitivity of the flapper arm. On Stromberg Carlson 71 and 73 ringers, this is done by loosening the THREE coil supports, which in turn moves the coil back and forth as shown in (1).
C. Older phone have adjustable hammer heads. Moving it further from the flapper pivot lowers the needed torque and frequency to move it, as shown in (2).
D. Changing the SERIES CAPACITOR (3) to a larger value lowers the resonant frequency. I used a 470 nF film capacitor (don't use polarized capacitors). Do this by connecting the ringer coil and capacitor to the audio generator and slowly adjust to see when the flapper deflects the most back and forth. This step needs to be done with trial and error, since capacitor values are up to 10% off.
E. Reassemble the ringer back into the phone. Try it on a real LAN line. May have to adjust the gongs for best sound. (<<See Video)

Local Area Network (LAN) Handset Telephones by Western Electric

1927-1984

(AT and T Manufacturing Division)

Western Electric Model 102 (B1 ROUND BASE) and Model 202 (D1 OVAL BASE) Rotary Dial1927-1937
Notes: Actual model is by base and handset.Most common combos:B1 base and E1 handsetD1 base and E1 handsetSubsets 634A and 684A
The 102 (B1 and E1) began in 1927. Represents Western Electric's first mass produced residential and commercial phone with a handset (receiver and transmitter combined) freeing one hand to take notes while talking. The 102 / 202 have no internal bell and network requiring stand alone ringer/network box.
The version shown has the D1 oval base body and later version E1 handset. Has a 5H dialer.

WE 202 Phone with WE 684 Subset (Actually 302 phone ringer which is the same in a 684 cover box.)

Western Electric 202

ABOVE: WE 302 phone base converted in WE 684 Subset.

ABOVE: Inside wiring around the 5H dialer assembly.

ABOVE: E1 handset for 202 phones. This version uses the 625A adapter to accommodate the newer and reliable F1 transmitter, replacing the original "bullet" transmitter that can fail over time.

BELOW: Restored WE 634A subset that would pair up with WE 202 phone.

The WE 634A used a metal box. Inside the WE 101A network coils and large metal can condenserswere used. The bell is also of the earler style wall phone ringers. A few years later the 684A would replace it and was about half the height. A plastic case would be used as well.

Western Electric Model 302 Rotary Dial 1937-1958
Design by Harry Dreyfuss design firm. Has built in ringer and was considered the "workhorse" of handset telephones especially during WW2. This was the first phone to have extension lines for office connections. Originally made of metal and evolved into thermoplastic molded due to WW2 demand for metal. Color variations of this phone were available.
This model telephone is similar to what my parents had about the time I was born

Unlike the 102/202 series phones, the 302 incorporates the B1A ringer and the anti sidetone and signal boost 101 series network in the same package, eliminating the subset. Uses a 5H dialer assembly.

Western Electric 302

ABOVE: F1 handset was used. Notice that Western Electric made the receiver element separate from the handset compared to the E1.

Western Electric Model 500C/D Rotary Dial1949-1984
The longest running model. Designed by Harry Dreyfuss design firm. Features easy to read dial and lighter G1 Handset. This is the first Western Electric phone to have all the electromechanical parts mounted on the chassis, making removal and servicing easier, avoiding wire tangling and breakage. The built in improved network and G series handset allowed the phone to handle longer distance phone calls without volume lost.
Soon after the phone company (Pacific Telephone one of the Baby Bells and now Verizon) offered my parents a newer model like the one above in basic black. In a few years the phone company offered colors for a one time fee added to the phone bill.

A big improvement over the model 300 series phone is the improved 425 series network over the 101 series. The anti-sidetone is improved along with greater gain for the transmitter and receiver handset through improved passive network configuration. This allows for longer distance from the telephone switching network and repeaters. Another big change is the the electrical and mechanical parts are mounted on the phone base.

Standardization of Telephone Technology in 1950's.

Manufacturers can share patents without being sued.

With the threat of legal action removed, companies wanted to provide the latest designs with minimal cost yet keep their character. That only lasted a few years, in time almost all phones looked similar. Only Automatic Electric made an effort to maintain their own style.

The Pseudo Western Electric 500 (5302) and the Real Western Electric 500

LEFT: model 5302 (1955-1962) and RIGHT: model 500 (1949-1984)

Appearances can be deceiving and that's what Western Electric counted on to save money. The 5302 was a recycled 302 but with a 500 style body. But one can show their friends they got the latest phone!

Western Electric 5302G Rotary Phone1955-1962 The 302/500 Model Hybrid (NOT A TECHNOLOGY CROSS OVER)
In the mid 1950's Western Electric had an alot of surplus 302 parts plus there was high demand for phones during the post war 'baby boom" They decided to provide the modern looking 500 series look but with 302 series parts inside. Some had the older F1 handset while others had the modified G1 (AKA GF) handset (G1 style in appearance modified to accept the F1 transmitter and receiver.
Basically it was a 302 series phone in a modified 500 series body. The body is shorter in the back and the body will accommodate a 302 dial and hook switch. (The 500 series has all the hardware on the mounting chassis). These phones were for local LAN lines and were assembled by the "Baby Bell" operations rather than western electric. They also came in different colors.

A mixed bag of technology. Under the model 500 styling is the older model 300 layout. Notice that a bell loudness feature was added (lower left corner). The handset in this version is a G1 on the outside like the 500 but the inside parts are those of the older F1 handset. The 5H dialer from the 302 series phones were used.

Notice on the upper left is a lever operated bell loudness control. The model 300 did not have loudness, while the model 500 has a thumb wheel adjust. BELOW shows the loudness control lever

Western Electric 5302

Comparison of the 5302G (Left) and 500 C/D (Right). Notice how much shorter the 5302G is (design to fit the model 302 base. Observe the difference in the modified G1 (or GF) handset of the 5302G and the standard G1 handset on the 500 C/D.

Western Electric 2500

Western Electric Models 1500 and 2500 Touch Dial 1968-1984
The Model 1500 was WE's first touch dial phone in 1964. It had 10 keys. Later WE added the * and # keys making the model 2500 with 12 keys. This is the first phone that had electronic circuits for the touch tone service.
When I moved out of my parent's home, I used model 500 until around 1980 when I bought a 2500. By then A T and T allowed the purchase of a phone. AT and T made available preowned 2500 models at a affordable price.

First Western Electric phone with electronic circuits (touch pad).

Touch Dialer electronics. Notice the round silver disk. That is the lone transistor (WE type 12D). One transistor multivibrator circuit with two tunable transformers and two fixed .0446 uF capacitors to set the DTMF tone frequencies.

Western Electric 700 series

"Princess"

Western Electric "Princess Series" 1959-1984. Rotary Dial mdls 701(1959-63) 702 (1963-84)
NOTE: 701 no ringer and needs E1 Subset
I planned to stop at the 2500 desk phones, but Western Electric finally made the telephone smaller and added extra features like a lighted dial and nightlight, with the Princess models. Was catered to those who wanted an extra phone (sign of luxury) and appealed to women for the bedroom decor. They came in many colors.

The Princess became the basis for Western Electric's most compact and last new model, the "Trimline" (Rotary 220 and touch dial 2120 and 2220) when the dialer or touch pad was mounted on the handset.

ABOVE: The 701B with the E1C Subset. The 701B had no ringer so the E1C was available if a ringer was needed. Also this subset provided the dial light interface with the 2102 transformer.BELOW: E1C subset ringer loudness control lever.

INSIDE THE 701 Princess. Notice that everything is built on the base. A 495 network is shown on the right. The dialer is the 8A. However the 701B does not have a ringer so an E1C subset was needed. In 1963 Western Electric designed a compact M1A bell to fit on the base to the left. This became the 702B. In the 701B a lead weight was used in its place to keep the base stable. Notice the pilot light near the center. A 2102A external power transformer was needed to provide 6-8 VAC at .25A for the bulb.

ABOVE: Base of the 701B. The round object is access to replace the light bulb ( GE#46 ) and the date of this phone is 1/1962, the last year of the 701B, replaced by 702B in 1963. BELOW is the G3 handset.

Western Electric 220 Series

"Trimline"

The Princess Phone leads to Trimline

Western Electric's last mass produced phone.

Western Electric Trimline (Rotary 220 and touch dial 2120 and 2220). The last volume production models by Western Electric from 1965- 2000's. After 1985, Lucinet, originally Western Electric produced it and other manufacturers made trimline "clones". The slimest phones of all Western Electric models, where the dialer, is part of the handset and the base has the bell and network. Like the Princess models, the Trimline featured illuminated dials when the handset is lifted. Most Trimlines used LED illumination eliminating the 2012 transformer.

Model 220 Handset assembly. The first phone to use flex circuit boards and have the dialer integrated with the handset.

Handset circuitry, contains part of the network circuits for the transmitter and receiver.

Base contains the bell, network inductors and external phone interface.

Western Electric 2220 Series

Touch Tone "Trimline"

Model 2220 Touch Dial (Early version) TrimlineThe early version used round buttons and a 51B light bulb (which required a 2012 transformer) to light the keypad. Western Electric's final version used square buttons and an LED for illumination with circuitry to eliminate the transformer.

Model 2220 Touch Pad Light: Like the Princess 2702 Phone, you lift the handset, the dial lights up.

BELOW: 2202 Base- similar to 220 model.

Vintage LAN Wall Telephones for Commercial and Industrial Applications

Automatic Electric Model 183 "Space Maker"
1958-1983
Space saver phones are wall mounted and were commonly used in commercial and industrial operations, where a desk phone is not practical. Has a built in network but no ringer. Can be used without a subset.

The AE 183 unlike WE Space Maker phones have a built in network. So only an external ringer is needed if a ringer was needed.

Kellogg F9751 "Masterphone" Space Saver Dial Wall Phone (1930's-1950s). Fairly compact compared to the other space saver phones.
