BRAKE FOR MOTOR VEHICLES.
Application filed anuaI'y 24, 1924. Serial No. 688,274.
To all whom t may cov/wem.'
Be it known that I, FREDERICK TASKERl BURGEss, a subject of the King of England, residing at London, England, have invented certain new and useful Improvements in Brakes for Motor Vehicles, of which the following is a specification.
This invention relates to brakes for use on motor vehicles, and it has for its Object to provide a very substantial pivotal attachment of the brake shoes upon the anchor plate, enabling the latter to be made of small weight, or, conversely, providing a very substantial construction for a moderate weight. I
Usually the anchor-plate comprises a disc formedwith an Overhung pin supported at one side only in the plate, and the shoes are mounted upon this pin.
According to the present invention, the plate is formed with'a radial web which is spaced slightly from the wall of the plate,
and the anchor pin for the shoes is mounted in this web, projecting at both sides thereof. It may also enter the wall of the plate as well, but the 'main point. is that the pin is centrally mounted' so that the shoes, which are forked at `their pivots, are mounted on both projecting parts of the peg.
In the case of a front wheel brake the anchor plate is usually dished and, according to a subsidiary feature of the present invention, this web lies in the'plane of the central portion of the plate, i. e., the plane of its attachment to the axle. Thus there is no tendency for the anchor plate to be twisted or buckled under stress due to the plate being otherwise than flat. l
The accompanying drawings show how the invention may be applied to brakes on tlie steering wheels of a motor vehicle. 'In t ese,
Figure 1 is a view from the inner side of the brake mechanism and F'gure 2 is a central vertical section of the same,
Like letters indicate likeparts throughout the drawings. y
In this construction the anchor plate A is dished and is formed with a large central hole A2 around which it is faced for attachment to a flange B2 on the axle B. The
plate is dished so that the edges lie considerably to one side of the plane of attachment, and at the bottom the platj has formed integral with it a depending web C which preferably lies in the plane of the ycentre of the plate, i. e., the plane of attachment of the plate. This web is spaced slightly from the rim of the plate and it is formed with a boss or bosses G to receive the anchor pins E for the shoes F. The pins may also enter ya boss or bosses such as H in the dished edge of the plate A and be fixed there by a pin K.
"The shoes F are forked at F2 at their pivotal ends, and these forked parts pass one each side of the web C and are held in place by thecross-pins E.
It will be clear that the latter is substantially supported and therefore the anchor plate can be o f small weight and yet be very little stressed, which is particularly important in the case of front wheel brakes wherein the stresses are extremely high.
What I claim as my invention and desire to secure by Letters Patent of the United States is l. In.a brake, the combination .of an an- Chor plate, a web on said plate, a fulcrum on lboth sides ofsaid web, and a shoe engaging substantially as set jecting on both sides of said web and entering said plate, and a shoe having a forked end pivoted upon said pin on both sides of said web, substantially as set forth.
4.A In a brake, the combination of a dished anchor plate, an attachment face on said anchor plate, a radial web integral with said plate and located in the same plane as said attachment face, a pin carried by and projecting on both sides of said web, -and a shoe pivoted upon bothy projecting parts of said pin, substantially as set forth.
Intestimony whereof I have signed my name'to this specification in the presence of two subscribing witnesses.
FREDERICK TASKER BURGEss.
