Canadian Brewers Modify Fruehauf Trailers to Achieve a Creative Solution
Trailer designed for Canada's Labatt's Brewing Company
The truck above was a delivery truck for Labatt's Brewing Company from the period of time just following prohibition. Brewery's or distilleries were unable to advertise, thus Labatt's resorted to making their delivery trucks as eye-catching as possible. This trailer and others which even had tractors that were of a then futuristic aero design performed the marketing duties of the day. A more complete overview which identifies the Fruehauf connection can be found here.
Partnering with Dow, Fruehauf implements Light-Weight Metal Walls
DOWMETAL - Shortly after World War I, Dow Chemical Company metallurgists developed an alloy called "Dowmetal". One-third lighter than aluminum, it was a refined magnesium to which was added about six percent aluminum and one-half percent manganese (a chemical used to harden magnesium). Dowmetal was widely promoted for automotive and aviation uses and was highly profitable for the company, eventually giving it a virtual monopoly on magnesium production in the US. Dow had a number of experimental Dowmetal open and enclosed car transport trailers built by Fruehauf for Detroit's White Star Lines in the early 1930s (1933), but evidence of automotive use after that time is lacking.
PARTIAL LIST OF FRUEHAUF KEY PATENTS 1919 - 1997
FRUEHAUF TRAILER COMPANY PATENTS – 1919-1946
US1313087 – Supporting Jack - Filed Feb 10, 1919 - Issued Aug 12, 1919 – inventor Ernest F. Hartwick - assigned to Fruehauf Trailer Co.
This device was created as a “supporting jack” to be used to hold up the end of a trailer, when the trailer is disconnected from its tractor.
********************
US1351245 – Fifth Wheel - Filed Dec 24, 1919 - Issued Aug 31, 1920 - inventor Ernest F. Hartwick - assigned to Fruehauf Trailer Co.
This invention relates to the connecting devices between automotive tractors and two-wheeled trailers, sometimes called semitrailers, and its object is to provide a novel fifth wheel and a simple, strong, self-closing locking device whereby the trailer may be secured to the tractor.
********************
US1850531 – Trailer vehicle - Filed Sep 7, 1923 - Issued Mar 22, 1932 - inventor Addi Benjamin Cadman - assigned to Fruehauf Trailer Co.
This invention was created to produce a vehicle in which the load on the trailer will be distributed more evenly over the rear wheels of the tractor and the trailer, so that heavier loads can be carried as well as better traction on the rear tractor wheels, and whereby the tractor and trailer may be coupled and uncoupled automatically with less shock than has been placed upon vehicles of this construction heretofore.
********************
US1568560 – Semitrailer - Filed Feb 8, 1924 - Issued Jan 5, 1926 - inventor Charles H. Land Jr. - assigned to Fruehauf Trailer Co. on Nov 13, 1928 as USRE17132.
When the tractor backs into the semitrailer, the latch hooks automatically to engage with the locking bar on the truck. The supporting unit then swings from its forward position to a vertical position during the travel on the truck tracks of the wheels on the front of the trailer frame.
********************
USRE17132 – Semitrailer - Filed Feb 8, 1924 - Issued Nov 13, 1928 - inventor Charles H. Land Jr. - assigned to Fruehauf Trailer Co.
(See above US1568560.)
********************
US1613728 – Trailer - Filed Mar 12, 1924 - Issued Jan 11, 1927- inventors Harvey C. Fruehauf and Charles Lawrence Schneider – assigned to Fruehauf Trailer Co.
This invention permits the lowering of not only the truck frame, but also the trailer frame, permitting the standardization of trailer frames. In high truck frames in a trailer of this design it has been necessary to build special trailer frames for each job. With the trailer frame dropped down below the tops of the wheels, this frame can be used in accordance with the needs of a particular job. They are ordinarily built of wood, making construction easier. This results in cost savings in trailer manufacture.
********************
US1540502 – Removable drawbar for vehicles - Filed Mar 27, 1924 - Issued Jun 2, 1925 - inventors Harvey C. Fruehauf and Charles Lawrence Schneider - assigned to Fruehauf Trailer Co.
This invention is in regard to trailer construction known as the reversible trailer. It can automatically and centrally lock the swiveling trucks to the trailer frame. It can also render the locking device ineffective when it is desired to tow the trailer and to allow the steering of the front swiveling truck. This invention also provides a tongue lock which allows the trailer to be coupled or uncoupled from the tractor allowing the trailer to be towed at either end, locking the trailer so that it will not become uncoupled from the tractor during transit.
********************
US1681433 – Vehicle Spring Suspension - Filed Aug 14, 1925 - Issued Aug 21, 1928 - inventor Frederick Malcolm Reid - assigned to Fruehauf Trailer Co.

********************
US1611947 – Semi-trailer and support - Filed Jul 9, 1926 - Issued Dec 28, 1926 - inventor Frederick Malcolm Reid -assigned to Fruehauf Trailer Co.
The current semi-trailer has a support in the form of a frame-like structure. The frame is secured to the trailer so that it can be lifted from the ground when the trailer is attached to the tractor. This lifting is accomplished automatically as the trailer locks in place. When the trailer is detached from the tractor it is held up by a support. This newly designed support prevents undue jamming and breaking of parts and damage when the trailer has been lifted.
********************
