Abstract
Abstract A wheel brake system for a truck or the like including a brake shoe having the usual semicylindrical band with a brake lining secured over its outer convex surface, but being provided with generally radially inwardly projecting apertured mounting lugs spaced along its arcuate extent. Each shoe further includes a pair of registered inner and outer arcuate plates over whose outer edge surfaces the concave inner surface of the band is disposed with the lugs carried by the band sandwiched and clamped between the plates by through bolts secured therethrough. The inner side plate, independent of the through bolts, is removably mounted in position whereby after the through bolts have been removed the inside plate may be axially withdrawn from the associated drum and the lining may thereafter also be axially withdrawn from the drum.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
171 words
A wheel brake system for a truck or other heavy duty vehicle, said brake system including a mounting bracket for securement to one side of an axle housing portion disposed within a brake drum, a pair of mounting pins supported from said bracket in position to generally parallel said housing, a pair of brake shoes each including a pair of parallel laterally spaced arcuate plates having corresponding heel ends removably oscillatably supported from the opposite ends of one of said pins, an elongated semicylindrical band having brake lining material secured to its outer convex surface and positioned with its inner concave surface overlying and extending along the outer convex edges of said arcuate plates, and a plurality of spacer blocks carried by said band and projecting inwardly between said plates from the concave surface of said band at points spaced therealong, and means removably secured between said plates securing said spacer blocks between said plates, whereby removal of the innermost plate will free said band for axial withdrawal from said drum.
Claim 2
Dependent Claim
171 words
A wheel brake system for a truck or other heavy duty vehicle, said brake system including a mounting bracket for securement to one side of an axle housing portion disposed within a brake drum, a pair of mounting pins supported from said bracket in position to generally parallel said housing, a pair of brake shoes each including a pair of parallel laterally spaced arcuate plates having corresponding heel ends removably oscillatably supported from the opposite ends of one of said pins, an elongated semicylindrical band having brake lining material secured to its outer convex surface and positioned with its inner concave surface overlying and extending along the outer convex edges of said arcuate plates, and a plurality of spacer blocks carried by said band and projecting inwardly between said plates from the concave surface of said band at points spaced therealong, and means removably secured between said plates securing said spacer blocks between said plates, whereby removal of the innermost plate will free said band for axial withdrawal from said drum.
Claim 3
Dependent Claim
23 words
The combination of claim 1 wherein said ends of said pins each include a sleeve bearing removably secured thereon against rotation relative thereto.
Claim 4
Dependent Claim
66 words
The combination of claim 1 wherein the toe ends of each pair of said plates has a roller journaled therebetween, an operating shaft for disposition on a second side of said axle housing remote from said bracket and adapted to be supported for rotation about an axis generally paralleling said axle housing, one end of said shaft having an S-cam thereon for disposition between said roller.
Claim 5
Dependent Claim
50 words
The combination of claim 3 including a pair of mounting brackets for securement to longitudinally spaced portions of said second side of said housing, a pair of journal members removably supported from said pair of mounting brackets, the other end portion of said shaft being journaled from said journal members.
Claim 6
Dependent Claim
28 words
The combination of claim 1 wherein the outer marginal edges of said plates are notched and seatingly receive the opposing longitudinal edge portions of said semicylindrical band therein.
Claim 7
Dependent Claim
23 words
The combination of claim 5 wherein said ends of said pins each include a sleeve bearing removably secured thereon against rotation relative thereto.
Claim 8
Dependent Claim
66 words
The combination of claim 6 wherein the toe ends of each pair of said plates has a roller journaled therebetween, an operating shaft for disposition on a second side of said axle housing remote from said bracket and adapted to be supported for rotation about an axis generally paralleling said axle housing, one end of said shaft having an S-cam thereon for disposition between said roller.
Claim 9
Dependent Claim
50 words
The combination of claim 7 including a pair of mounting brackets for securement to longitudinally spaced portions of said second side of said housing, a pair of journal members removably supported from said pair of mounting brackets, the other end portion of said shaft being journaled from said journal members.
Claim 10
Dependent Claim
118 words
A brake shoe construction including a pair of parallel laterally spaced arcuate plates, an elongated semicylindrical band having brake lining material secured to its outer convex surface and positioned with its inner concave surface overlying and extending along the outer convex edges of said arcuate plAtes, a plurality of spacer blocks carried by said band and projecting inwardly between said plates from the concave surface of said band at points spaced therealong, and fastener means removably secured through said plates and said spacer blocks securing said plates to the opposite sides of said spacer blocks, and elongated connecting members removably secured between each pair of corresponding ends of said arcuate plates for support of said shoe construction therefrom.
Claim 11
Dependent Claim
118 words
A brake shoe construction including a pair of parallel laterally spaced arcuate plates, an elongated semicylindrical band having brake lining material secured to its outer convex surface and positioned with its inner concave surface overlying and extending along the outer convex edges of said arcuate plAtes, a plurality of spacer blocks carried by said band and projecting inwardly between said plates from the concave surface of said band at points spaced therealong, and fastener means removably secured through said plates and said spacer blocks securing said plates to the opposite sides of said spacer blocks, and elongated connecting members removably secured between each pair of corresponding ends of said arcuate plates for support of said shoe construction therefrom.
