EDWIN G. BUSSE AN D GEORGE N. VAN SWERINGEN, OF CHICAGO, ILLINOIS, ASSIGNOES TO CHICAGO RAILWAY EQUIPMENT COMPANY, OF CHICAGO, ILLINOIS, A CORPO- RATION OF ILLINOIS.
BRAKE HEAD.
Application filed January 19, 1920. Serial No. 352,521.
To all whom it may concern Be it'known that we, EDWIN G. Bnssn, and GEORGE N. VAN S'WERINGEN, citizens of the United States, residing at the city of a Chicago, county of Cook, and State of 1111- nois, have invented a certain new anduseful Improvement in Brake Heads, of whlch the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a side elevational view of our it improved brake head.
Figure 2 is a detail view of one of the renewable wearing surfaces.
Figure 3 is a detail view of another form of renewable wearing surface.
Figure 4 is a side elevational view of the brake head provided with different forms of renewable wearing surfaces.
Figure 5 is a front elevational view of the form shown in Figure 4.
Figure 6 is a side elevational view of a modified form of brake shoe having renewable lugs.
Figure 7 is a partial front elevational view of the form shown in Figure 6.
This invention relates to a new and useful improvement in brake heads in which. the lugs or the wearing surfaces thereof are made renewable. When a brake beam is improperly mounted, the brake shoe wears unevenly oftentimes wearing away entirely at top and bottom and wearing into the toes or lugs of the brake head; also, if the fit between the brake head and brake shoe is not close there is more or less play or lost 4w motion between the shoe and head, which increases with the length of service frequently to the extent of wearing away the toes or lugs. It is the practice with certain railroads when such, condition arises to weld an additional wearing piece on the head to replace the toe 'or lug which has been worn or ground off. In many cases, the top and bottom toes only are Worn or rubbed away, leaving the balance of the head in perfect condition.
It'is the purpose of the present invention to lengthen the life of the brake shoe head hy P i g it with individual renewable have shown the lugs or toes faced with hardened steel plates 2 riveted in position by rivets 3.
In Figure'3 is shown a locking lug 5 by which the hardened steel wearing surface may be interlocked with the lug or toe of the brake head. I
In Figures 4 and 5, the renewable'wearing surface 6 is provided with a projection 7, by which it, is attached to the lug of the brake head by means of a rivet 8, Whereas in Figures 6 and 7 the entire toe or lug 9 is removable and renewable, the same being preferably provided with a dovetail interlocked with the brake head and held in position by means of a rivet 10.
What I claim is:
1. A brake head comprising a body integral from end to end, and individually renewable shoe supporting elements independently secured to said body.
2. A brake head comprising a body adapted to extend throughout the length of the brake shoe and integralfrom end to end and provided with renewable shoe supporting elements at intervals along its surface.
3. A brake head comprising a body hav- ,ing' a portion adapted to be mounted on the end of a brake beam and having integral extensions which are provided along their faces with undercut recesses spaced at substantial intervals, and renewable undercut lugs sions, renewable shoe supportng lugs at opposite ends thereof, and renewable shoe supporting lugs intermediate said first-mentioned lugs. l
6. A brake head comprising a body, and relatively short individually renewable shoe supporting elements independently mounted on and secured to said body adjacent to the point at which they support the shoe.
In testimony whereof we hereunto afiix 10 our signatures this eighth day of December, 1919.
EDWIN G. BUSSE. GEORGE N. VAN. SWERINGEN.
