BRAKE HEAD AND SHOE.
SPECIFICATION forming part of Letters Patent No. 331,894, dated December 8, 1885.
Application filed September 14, 1885.
To all whom it may concern.-
Be it known that 1, JOHN JOSEPH LAPPIN, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in the Connecting Parts of Brake-Heads and Brake-Shoes; and I do hereby declare that the following is a full, clear, and exact description of the same.
My invention relates to a brake-head and brakeshoe now in use; and it consists in the enlargement of the bearing parts of the brake-head to a quadruple of their present size, and hardening the said parts upon a chill, so that they will remain uniform, and in lengthening and enlarging the ribson the back of the brakeshoe proportionally to the enlarged bearing and fitting parts of the brake-head, to prevent any lateral motion of the shoe on the brake head, and in the heightening of the songs which the ends of the shoe fit up to and are longitudinally locked between, as hereinafter more fully described in the specification, and pointed out in the claim.
In the accompanying drawings, Figure l is a side view of a brake-head embodying my improvements, with an improved brake-shoe attached thereto. Fig. 2 is a back view of the brake-head and shoe behind the same. Fig. 8 is a face view of the brake-head. Fig. 4: is a plan view of the brakehead and brake shoe. Fig. 5 is a transverse section through the line a b in Fig. 1. Fig. 6 is a side view of the brake-head and chill. Fig. 7 is a face view ofthe chill. Fig. 8is aside view of brakeshoe without the brakehead.
Similar letters of reference indicate the same parts in all the views as in this specifi cation.
A represents the brake-head with groove a; B B, the flanged brackets-one on each sideformiug parts thereof; 0, a key for securing the brake-shoe to the brakehead; D, a brake-shoe; E, a hole in the brake-head for hanging the brake to the truck of the car; F, the bearing parts of the brake-head, which are hardened upon a chill in casting the same; F, the chill; f, theseats of the ohill,which fit the bearing parts of the brake-head. a, a are two checks in the face of the brake-head; d, a tongue on the back of the brakeshoe, which fits between the cheeks aforesaid.
Referring to Fig. 1, it will show the brakehead A and brake-shoe 1) connected and in Serial No. 177,043. (No model.)
the position as when applied on the rim of a car-wheel. It also shows the flanged brackets B, which hold the cross-beam of the brake, and the key 0, which connects the brake-shoe to the brake-head.
Referring to Fig. 2, it will be seen that the flanged brackets 13 are attached to the brakebeam by two bolts, which is an improvement on the common mode of attachment with one bolt only.
Fig. 3 shows the inner face of the brakehead, with the cheeks c a, flanged bracket B, bearing-surfaces F F F F, and key 0. The said bearing-surfaces are increased four to one, or four times.
Fig. 4 shows the brake-shoe D in connection with the brake-head, the flanged brackets 13, key (3, and enlarged rib d, projecting above the cross-snug d.
Fig. 5 shows key 0 and rib d Referring to Fig. (3, the brake-head A is shown lying On the chill F, in their relative positions as when the head is being cast in the foundry. The bearing-surfaces F of the brake-head are also shown, and the bearingsnrfaces of chili f" f /"f which harden the bearingsurfaces of the brake-head.
Fig. 8 shows the shoe A and the parts thereof which form the connections with the b'rake-hezulviz., thetongue (2, through which the key G passes and secures the shoe to the brake l1eadshowing also the enlarged ribs (1", the seats for brakehcad (13, and the enlarged snugs (1.
Having thus described my invention, 1 claim as new, and desire to secure by Letters Patent, as follows:
A brake-hcad,A, with groove o and flanged brackets 13 13, having its bearing parts F FF F enlarged and hardened upon a chilhas specitied and described, and made to fit enlarged seats (1 with heightened snugs d on the back of the shoe D, to provide for the better wear of the parts and their remaining uniform, and the groove a deepened and enlarged to span and fit a lengthened and enlarged rib, (i on the back of the shoe D, to prevent lateral motion of the shoe on the brake head, and to re lieve the key 0, which keeps the brake head and shoe together, of any more than a nominal strain thereon, the whole constructed and operating substantially as set forth.
