Cleaver-Brooks Company During World War Two
Milwaukee, WI

1929-1931 as the John C. Cleaver Company in Milwaukee, WI
1931-1970 as the Brooks-Cleaver Company in Milwaukee, WI
1970-2006 in partnership with the Coca-Cola Company among other owners
2006-Current as the Brooks-Cleaver Company in Thomasville, GA

This page added 9-26-2023.

 In 1929, John C. Cleaver, an engineer, created a company in Milwaukee, WI with his own name as the John C. Cleaver Company.  In 1931, Mr. Cleaver teamed up with east coast businessman Raymond Brooks and the Cleaver-Brooks Company was formed to manufacture and market a packaged steam boiler.  In 1992, Cleaver-Brooks purchased the Industrial Boiler Company of Thomasville, GA.  With this purchase, the company closed out its manufacturing operations in Milwaukee.  Currently, the company has its headquarters and a large manufacturing plant in Thomasville, GA.  It also still has several facilities located in Wisconsin. 


The Cleaver-Brooks Company won the Army-Navy "E" Award three times during World War Two.
The following Milwaukee plants were included in receiving the "E" Award:  Main plant, East plant, Port Washington Plant, and the Silver Spring Plant.

Cleaver-Brooks Company World War Two Products:  The Cleaver-Brooks Company had a total of $34,149,000 in major contracts during World War Two.  This amount included the production of distillation units, ship boilers, construction equipment, bathing units, disinfectors, medical equipment, asphalt heaters, generating plants, machine tools, railroad car parts, shower bath units, and cargo trailers.

Of interest for this page on the company is its manufacture of trailers for both the U.S. Navy and U.S. Army during World War Two.  My research so far has only found one of these trailers to still exist in a museum in the United States.

Table 1 - Cleaver-Brooks Company's Major World War Two Trailer Contracts
The information below comes from the "Alphabetical Listing of Major War Supply Contracts, June 1940 through September 1945."  This was published by the Civilian Production Administration, Industrial Statistics Division. 
Product - Customer Contract Number Contract Amount Contract Awarded Date Completion Date
Cargo Trailers - Navy QM-44790 $574,000 5-1944 7-1944
Cargo Trailers - Navy QM-44790 $2,032,000 1-1945 5-1945
Cargo Trailers - Army 11022-ORD-7866 $1,082,000 2-1945 7-1945
Amphibious Trailers - Navy QM-48498 $907,000 5-1945 10-1945
Total   $4,595,000    

 

Table 2 - Cleaver-Brooks Company World War Two Vehicles Accepted by Detroit Ordnance, US Army
The information below comes from "Summary Report of Acceptances, Tank-Automotive Material, 1940-1945"
Published by Army Services Forces, Office, Chief of Ordnance-Detroit, Production Division, Requirements and Progress Branch January 21, 1946.
Type Cleaver-Brooks Model Contract Number 1941 1942 1943 1944 1945 Total
Trailer, 2-1/2 Ton, 2W, Cargo, Amphibious WTCT-6 11022-ORD-7866         500 500

Information from Table 1 and Table 2 shows that the 500 WTCT-6 amphibious trailers cost $2,164 each.  From this information the estimated number of amphibious trailers purchased  on the three Navy contracts can be calculated.  The total of the three Navy contracts is $3,513,000.  This amount divided by $2,164 gives an estimated number of Navy trailers of 1,625.


The only known Cleaver-Brooks WTCT-6 amphibious trailer is on display at the national Museum of Military Vehicles in Dubois, WY.  The WTCT-7 in this photo is attached to the DUKW.  The main entrance to the museum can be seen above and behind the trailer.  Author's photo.

 One of the first things a visitor will see upon entering the museum is this Cleaver-Brooks WTCT-6 amphibious trailer.  In all of my visits to many military museums throughout the United States, this is the only one I have encountered.  These trailers and other similar models produced by Cleaver-Brooks Company were designed to be pulled behind DUKWs, as is depicted here.  They could also be pulled behind LVTs.  In both cases, they provided extra ammunition, food, and medical supplies to be delivered to the marines and soldiers during invasions of Japanese held islands in the Pacific Theater of Operations.  Part of this trailer is missing.  The main storage hold originally had a water proof hatch over it.  The hinges for the door can be seen along the edge of the storage hold.  Author's photo.

 The tie down eye bolts for securing the missing water proof hatch can be seen in this photo.  Author's photo.

Remaining Cleaver-Brooks Manufacturing Plants in Milwaukee, WI:  During World War Two, the company had a large manufacturing presence in Milwaukee.  Currently, that has all disappeared as the main headquarters and manufacturing plant are now located in Thomasville, GA.  From the information on the company's Army-Navy "E" award, Cleaver-Brooks had plants known as the main plant, east plant, Port Washington plant, and the Silver Spring plant. 


This former factory at 326 East Keefe Avenue in Milwaukee appears to have been the main plant.  Historical records show it was built in 1930 and occupied by the Cleaver-Brooks Company.   Image courtesy of Google Maps.

This Cleaver-Brooks research and development facility is currently located at 3232 West Lancaster Ave. in Milwaukee.  It was built in 1935 by the Cleaver-Brooks Company.  Image courtesy of Google Maps.

This facility at 3707 North Richards Street in Milwaukee is just east of the main plant on East Keefe Avenue.  Most likely this was the east plant cited on the company's "E" award.  This was the address that was given for the company in several newspaper job placement advertisements' in the mid-1960s.  Image courtesy of Google Maps.
