First off, I know this will interest very few collectors, and this effort may be futile, but I wish to share and hopefully get some feedback on this effort.
I've been doing some reasearch on the General Industries "Slasher" record changer which was manufactured through much of the 1930s.
There is precious little information out there about them, but here is what i have gleaned from a few sources. I do want to thank Fred Rice for some help here.

The changer appears to have been patented by two people. John R Mitchell and Paul U Lannerd under patent number 1,936,335 filed June 1932 and granted Nov 1933. In the book "Homer E. Capehart, A Senator's Life" by William B. Pickett, I find that John and Paul were engineers at the Capehart Corporation of Huntington Indiana (Later Fort wayne) and were "Let Go" around the time Homer Capehart was "Let Go" of his own company in February 1932.

Homer Capehart bought the Packard Piano Company of Fort Wayne and changed it to the Packard Manufacturing Corp. He enlisted the services of John and Paul, who were developing the changer at the Capehart factory. What is interesting is the patent mentions it was assigned to the Royal National Manufacturing, Inc. but for some odd reason, the location was cut-off. The only Royal National Company, Inc. I could find was an export division in NYC of for Gould-Moody who made record blanks. What the connection was, I've no idea.

Anyhow, it appears Mr. Capehart manufactured the "Slasher" changer in his new factory and it appeared under the 'New Merchandise" section of Radio Retailing. Then it was advertised in the December 1932 issue. I'm sure he advertised in other publications too.

The book mentions he approached Wurlitzer to buy these changers and Farny Wurlitzer agreed to purchase some of them to install in Lyric radio phonographs. I also know the 1933/34 Zenith model 476A console used one. Farny did ask Mr. Capehart about the idea of a selective coin operated phonograph changer as Prohibition ended, it might be a market to sell coin-op phonographs to bars and pubs. Capehart quickly secured the "Simplex" mechanism and the Wurlitzer Jukebox came to be. Wurlitzer then hired Mr. Capehart. During this time, it appears Packard only manufactured accessories and the Packard changer was either sold off to, or given license to General industries to manufacture.

The first advertisement in Radio retailing from General Industries on the changer was in the March 1934 issue. In that ad, they show a Webster horseshoe magnet pickup. The Packard changer shows what appeared to be the Webster flat magnetic pickup.

GI advertised the changer regularly in Radio Retailing. In February 1935, it shows the same flat Webster pickup the Packard version showed.

Also, General Industries included the 33 1/3 RPM speed in this changer for the RCA long play records. (Not the Columbia Microgroove which appeared in 1948)

The changer was advertised as model L which would change either 10" or 12" records or model K which would only change 10" records. It would play 12" manually. It appears the Packard version would only change 10" records as well.

In June 1934 and April 1936, Paul U Lannerd patented revisions to the changer which were granted 2,191,214 and 2,191,215 in February 1940 under General Industries.

GI came out with the "Improved" model M to replace the L advertised in January 1938 which also had a straight Astatic tone arm. Also by July 1937, there was no longer a mention of the 33 1/3 RPM speed. It also appears there was a choice between a Crystal or Magnetic pickup.

March 1939, GI introduced the "Tangent Tracking" tone arm with an Astatic crystal pickup having the pickup at an angle at the end of the tone arm.

The last ad was in the September 1939 issue of Radio Retailing. and GI introduced a new changer, the C120 in the July 1940 issue of Radio Retailing.

I hope this helps shed some light on this changer. I will add more as I find more info.

Steve, -
Do you have a copy of the John Rider's book: Automatic Record Changers and Recorders ?
I have the 1941 edition. Seems to have info on the General Industries Model "L". pages 238 to 241.
Parts layout, operating instructions, lubrication, trip mechanism, record removing mechanism, etc.

Dave, I sure do! :D

It is a very valuable resource!

Thanks!

Actually, it does the change in one 33 1/3 RPM revolution.
The motor, whether or not it has the speed change mechanism has the ring which catches the mechanism rotate at 33 1/3 while the center spindle rotates at 78.

The motors which have a speed change has a sliding collet which has the center spindle either engages the 78 RPM rotating gear or the 33 1/3. I hope to illustrate this at a later time once I've created enough room on the bench to tear down one of the GI Flyer motors.

Thanks for the interest! :D

Thanks Kirk!

I found a few illustrations of the motor assembly. It is quite the mechanism with an electric motor, gear box and governor.

I hope it helps show how it works. The record changer actuation ring is connected to the slower moving 33 1/3 RPM gear.
It doesn't show the protrusion of that shaft which is around the turntable platter shaft, but it is there.

Evidently, this motor assembly was in production from the early 1930s until the 1950s The manual I snagged these illustrations is from a military service manual dated November 1955.
Quite a run for a Rube Goldberg motor!

-Steve

A little two-speed manual transmission.

Thank you for the comments :D

I discovered a little tidbit about the motor. They were available with a standard AC induction motor OR a universal AC/DC powered motor with a commutator.
I tried moving an AC only induction motor to a gearbox which had a universal type.

It wasn't possible as the worm gear on the motor shafts have a completely different pitch.

The universal motor runs at a slower speed than the induction motor.

Thank you so much for sharing. I recently restored a Capehart which uses two of those same motors on the same shaft. It also has 33 1/3 rpm, and the same mechanism for shifting. Jon this is the one you helped me figure out the trip. Until now I had suspected this was the machine Homer Capehart had pitched to Wurlitzer, but you have not documentation for this one instead.

I've been looking for evidence of a Wurlitzer Lyric radio with one of these changers installed, but I have yet to find any.

It seems radio production ended and the work on the Wurlitzer jukebox began.

The Flyer motors as used in the Capehart. The two motors are mounted on same shaft with the gearbox in-between. Only one (nearer the governor" is powered during play; the other (and capacitor) is energized on only during the change cycle. The Thomas Small patent for this machine describes only one motor. That patent is not listed in the Capehart ID plate.

Very interesting! Ive never seen one with two motors!

I suspect this is the so called "Windsheild Wiper" style Capehart changer?

Thanks for sharing! This is all fascinating :D

Steve you must really know your changers. Yes, that's the one. I should post a video somewhere soon, it's quite a fascinating machine

Thanks, these early mechanical changers fascinate me! I would love to find a Capehart with your changer, but they are few and far between.
