Originally established as the
Rochester Coil Company in 1908, the company began manufacturing coils
and repairing electric motors. It was reorganized into the Northeast
Electric Company in
1908. Its first new product was a combined starter and generator
available in 1911. Northeast was purchased by General Motors in 1929 and was consolidated with
Delco Light Division in Dayton in 1930 to become Delco Appliance
Division. When Delco Light products were moved to Rochester, NY
from Dayton, OH in 1963, Delco Appliance was merged into Delco Products.
Delco Appliance Division of GM
World War Two Products:
Aircraft: Solenoid Shifters that controlled the hydraulic unit
that changes gears on an aircraft supercharger, Aneroid Switch that
controlled the gear changes as an aircraft went through altitude changes,
and the Aneroid that automatically controlled the air flow from the
supercharger. The division also built aircraft magnetos.
Naval: Engine
cutout switches for the Packard engines that were used in PT and
63-foot, 85-foot, and 104-foot rescue boats.
Motors: 15,000 motors for F-20 aerial reconnaissance cameras,
radio transmitter twin blowers, lamp housing blowers,
fire control motors, computer motors, antenna-driving motors, general
purpose torque motors, periscope gun sight motors, aerial camera motors,
gun charger timer motors, bombsight motors, automatic pilot motors, and
gyroscope gun sight motors
Gun Directors: M5 Gun
Directors for use with U.S. Army 37mm and 40mm anti-antiaircraft
guns.
Auxiliary Generators:
Delco Appliance furnished auxiliary generators for 2,074 M5 and 6,819 M5A1 Stuart Light Tanks. It
also supplied 1,778 auxiliary generators for the M8 self-propelled 75mm howitzer gun carriage
built on the Stuart chassis. The division also supplied 7,225 auxiliary generators for the LVT-1
tracked landing craft.
The Delco Appliance
Division won the Army-Navy "E" Award four times.
The first award was
presented on September 22, 1943.
This M45 Quad Mount is on display at Roberts
Armory in Rochelle, IL. Of interest in this photo is the generator
that was used to charge two six volt batteries wired in series which
powered the gun turret. The original M45 Quad Mounts were equipped
with a Briggs & Stratton PC-1 generator. In this particular case,
Roberts Armory has replaced the PC-1 with a Delco Appliance auxiliary
generator from its M5A1 Stuart tank. The Delco Appliance part
number is either a DA5066666 or DA5067720, depending on when the M5A1
was built. Author's photo added 6-3-2021.
The use of this Delco Appliance auxiliary
generator in the M45 Quad Mount allows for a full view of the device.

tanks with serial numbers 1 through 800, 2268 through 2368, and 3268
through 3367. Delco Appliance part number DA5067720 was used in
Stuart tanks with serial numbers 801 through 2267, 2369 through 3267, and

This is the M5A1 Stuart light tank at
Roberts Armory from which the Delco Appliance auxiliary generator was
taken for the M45 Quad Mount. Delco Appliance built 8,893
auxiliary generators for the M5/M5A1 series of light tanks.

The M8 self-propelled 75mm howitzer gun
carriage was built on the M5 chassis. Delco Appliance also supplied
1,778 auxiliary generators for this vehicle. Author's photo added

This World War Two magazine ad associates
the M5 tank and Delco Appliance generators. The term "Little Joe"
was a generic term used by World War Two soldiers for any small
generator that provided electrical power. The ad notes that the
Delco Appliance generator derives from the line of home lighting
generators originally produced by the Delco-Light Division of General
Motors.
Delco Appliance supplied Delco Light
7,225 auxiliary generators that were used on USMC and U.S. Army LVT-1 amphibious vehicles.
This was Delco Appliance model number 5067440. Author's photo added 2-10-2019.

auxiliary generator 5067440. Image added 9-26-2021.
Delco Appliance had previous experience
building small generators for farm lighting when it combined with the
Electric-Light Division of GM. This example is at Carillon Park in
Dayton, OH. Author's photo added 7-28-2021.
One application of Delco Appliance World War Two products is an
automatic ignition cut-out used on Packard-built PT boat
engines. At high speed in rough waters, the propellers could come
out of the water. This could cause the engines to over rev. The
Delco Appliance device prevented this. This one is at the National War in the Pacific Museum in
Fredericksburg, TX.
American PT boats like Higgins Industries
PT-305 would have the Delco Appliance engine cutout on the Packard
engines. Author's photo added 2-10-2019.
This Eastman Kodak K-24 aerial
reconnaissance camera is on display at the Museum of Military History in
Kissimmee, Fl. The motor in the upper left of the camera was built
by Delco Appliance. Author's photo added 7-28-2021.
The camera was used in many American
aircraft including the photo reconnaissance versions of the B-24, P-51,
and B-25. Author's photo added 7-28-2021.
Eastman Kodak and Delco Appliance were both
located in Rochester, NY. It only made good business sense for
Kodak to utilize Delco Appliance to provide the fractional horsepower
motors to advance the film in the camera. Author's photo added
7-28-2021.
The motor was Delco Number 7524 and Eastman
Number U7694. Author's photo added 7-28-2021.
Delco Appliance is on display at the
National Museum of the United States Air Force in Dayton, OH. It
is part of a display on photo reconnaissance and photo interpretation.

A Delco Appliance fractional horsepower
motor is mounted to this Fairchild F-20 aerial camera. Folmer
Graflex built approximately 15,000 of these cameras under license from
Fairchild. Author's photo

Delco Appliance was one of at least two
manufacturers that produced the M5 Gun Director for use with 37mm and
40mm anti-antiaircraft guns used by the US Army.
