BRAKE Original Filed Febp4, 1935 IN VEN TOR.
A TTORNEY 2,064,616 PATENT OFFICE BRAKE Ludger- E. La Brie, Detroit, Mich, assignor to Bendix Products Corporation, South Bend, Ind., a corporation of Indiana Original application February 4, 1935, Serial No. 4,802. Divided and this application March 21,
1936, Serial No. 69,999
4 Claims.
This invention relates to brakes, and is illustrated as embodied in brake shoes intended for use in an internal expanding automobile brake.
An object of the invention is to provide a light and strong shoe, preferably sufliciently flexible to conform to a brake drum even if the drum is not entirely accurate in shape or mounting, and which is formed to engage an anchor at one end and an adjusting device at the other end, and which has two notches adjacent its anchored end for engagement with two alternatively-operable applying devices.
The above and other objects and features of the invention, including various novel and desirable structural features, will be apparent from the following description of the illustrative embodiments shown in the accompanying drawing, in which:
Figures 1 and 2 are side elevations of two shoes embodying my invention.
The shoe shown in Figure 1 includes a rim E0 to which is riveted or otherwise secured the usual brake lining l2, and which is integral with or has welded or otherwise secured thereto along its center line a stiffening web M. The web It is shown formed with gage openings 66 and with other openings l8 for the attachment of return springs and for steady rests and the like.
According to the present invention the shoe web is formed at its upper end with a surface, preferably a concave or partially-circular notch 20, for engagement with a suitable brake anchor such as a fixed post 22. The lower end of the web i4 is formed with a wide shallow notch 24 for engagement with a suitable adjusting device such as is shown and described in my parent application No. 4,802, filed February 4, 1935, and
- of which the present application is a division.
Between the upper or anchor-engaging end and the center of the shoe, the web i4 is also formed with two notches 28 and 39 having convexly-rounded bottoms, and which areadapted to engage two alternatively-operable brake-applying devices, as described in my above-identifled parent application.
All four notches 20, 24, 28 and 3B face in the same direction, away from the rim. 10, i. e. in a direction paralleling the horizontal diameter of the brake in the arrangement illustrated, where the brake anchor is at the top of the brake and the adjustment is at the bottom.
Between the notches 2t and 30 the rim is reduced slightly in width, so that the shoe has a slight degree of flexibility, sufiicient to permit the shoe to conform to a drum which is slightly out oi round or slightly off center.
The shoe of Figure 2 difiers from that of Figure 1 mainly in that the web H4 is reduced in width considerably more between notches I24 and 30, to make the shoe somewhat more flexible, and in that the lower side of the notch I24 is formed by a projecting or overhanging part of the rim it.
While two constructions have been described in detail, it is not my intention to limit the scope of the invention .by that description, or otherwise than by the terms of the appended claims.
I claim:
1. A brake shoe formed with a rim and a web, the web being formed at opposite ends with surfaces adapted to engage respectively an anchor and an adjusting device, and said web having adjacent the anchor-engaging end two notches facing away from the rim and having rounded bottoms, for engagement with two applying devices.
2. A brake shoe formed with a rim and a web, the web being formed at opposite ends respectively with a concave notch adapted to engage an anchor and with a shallow notch adapted to engage an adjusting device, and said web having adjacent the anchor-engaging end two notches facing away from the rim and having rounded bottoms, for engagement with two applying devices, all four of said notches facing in the same direction.
3. A brake shoe formed with a rim and a web. the web being formed at opposite ends with surfaces adapted to engage respectively an anchor and an adjusting device, and said web having adjacent the anchor-engaging end two notches facing away from the rim and having rounded bottoms, for engagement with two applying devices, said web being reduced in height between the two notches and the end engageable with the adjusting device, sufiiciently to make it diiilcultly flexible.
4. A brake shoe formed with a rim and a web, the web being formed at opposite ends respectively with a concave notch adapted to engage an anchor and with a shallow notch adapted to engage an adjusting device, and said web having adjacent the anchor-engaging end two notches facing away from the rim and having rounded bottoms, for engagement with two applying devices, all four of said notches facing in the same direction, said web being reduced in height between the two notches and the end engageable with the adjusting device, sufficiently to make it diflicultly flexible.
