BRAKE-SHOE. I

Specification of Letters Patent. 1 Patented Sept, 15 1914 Application filed March 10, 1914. Serial N 0. 823,748.

To all whom it may concern i p Be it known that I, HARRISON J. CAMP, a

' citizen of the United States, residing at New which the following is a specification.

"Berlin, in the county of Chenango and State ofNeW York,have invented certain new and useful Improvements in Brake Shoes, of

v This invention relates-to improvements in brake shoes for rolling stock.

The object of the invention is to improve the construction of brake shoes for rolling stock, vparticularly locomotives, and to provide an extremely simple and inexpensive brake shoe having fastening means adapted tohold the brake shoe on a brake head until the said shoe is entirely worn out. A further object of the invention is toprovvide a brake shoe having fastening "means appended hereto and form a adapted to effectively prevent the brake shoe from falling off the brake head and be-;

- corresponding parts throughout the'se'veral "views, and 111 wh ch .Flgure 1 1s a'perspeo.

tive View of an assembled brakeshoe illustrating the application ofthe invent1on;;

Fig. 2 is a similar view. of the said shoe, the; constituent parts thereof bein separately shown; and Fig. 3 is an inverte end view.

Before proceeding with the "description:

i of the drawings, I desire to call particular,

attention/to the fact that while I have evolved my invention with reference to its application in connection with rolling stock,

particularly locomotives, "the same maybe readily utilized as a brakev shoe for wagons,

carriage, and other vehicles varying intype; lteferrlng'now to the drawings by numo l 1 designates, asan entirety, the head by thenumeral 4 abuts.

portion of the shoe, said head being provlded with a central opening 2 for the reception of thebrake beam (not shown). Sa1d head 1 is grooved as indicated at 3, the groove extending entirely around the head and longitudinally thereof at a point adjacent thatface of the head against which the brake shoe proper designated as an entirety The said face of the head 1 is centrally recessed as at 5 to .provide for the reception of an enlargement 6 of the shoe4 to tightly engage, when the shoe is assembled, shoulders,designated respectively 7 and 8' formed atrthe respective ends of the said recess. Said'shoe tis also grooved as indicated at 9, said grooves likewise extending longitudinally' of the shoe in spaced relation to and adjacent the inner or head engaging faceof said shoe. Shoulders l0 and 11 are formed at the respective ends of the enlargement 6, said shoulder 10 being adapted for engagement with the shoulder 8 of the head, and the shoulder 11 being adapted for engagement with the shoulder 7 of the head, which engagement,

the said shoe and head beingproperly assembled, will lock the one against longitudinal movement independent of the other. Y The opposite face of the shoe 4 from that abutting the head 1 is arcuately formed as indicated at 12 for an obviouspurpose;

Attached, as indicated at 13 to the head portion 1 of the shoe is a retainingplate 14,

the respective ends of 'which' are upturned as at 15 to fit the respective grooves 3 and 9 of the head and shoe. One of thesaid up- .turned ends 15 is at all times within, the groove 3, while the other of the said ends 15, upon the separation of the shoe from the head, is withdrawn from engagement with the" said groove 9. The shoe and head being assembled, a fastening member, designated as an entirety by the numeral 16 isarranged thereove-ryto maintain the said shoe 'headln llgldTGlLtlOIl, saldfastenlng member being substantially U-shaped in form, therespective extensions thereof as well as the connecting portion, being provided with longitudinal flanges, one upon each ofthe respective longitudinal edges thereof. Said flanges, as indicated in F igs. 1 and 2 of the drawings, fit the grooves 3 and 9 to in this manner look the shoe and head as desired.

v As a means whereby the fastening member 16 is maintained with its several flanges within the grooves 3 and '9, a retaining pin I 17 of the cotter type, is provided, said pin beingyinsertable through openings 18 of the fastening member and through a groove 19 extending transversely of the shoe 4 and in registration or alinement with the said openings 18. To facilitate removal of the fastening member 16, a ringQO, or other like element, is attached thereto.

When it 'is' desired that the several elements comprising the shoe, be separated or upturned ends 15 and the shoe serving-as afulcrum during separating operation. Said shoe having been separatedtothis extent by disengagingthe shoulder 10 and the shoulder 8, the former, that is the shoe 4, may

be} longitudinally moved to entirely separate or-disengage the A reverse operation to that just described,

will provide forthe rearrangement of the;

' several componentparts. 5

readily and quickly replaced, by the withdrawal of the' fastening member 16 from engagement with the shoe; --that either the head orthe shoe 4, maybe removed, renewed, and replaced, the two being made separate for that particular purpose; and that toprovide for the separation ofthe said head and shoe,lthe shoulders 8 and 10 are slightlybeveledasindicated in-the said Fig '2 of the drawings5gv a a In reductionto practice, I have found thatthe form ofmy invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment,I is the most efficient and practical; yet realiz ing that the conditions concurrent with the adoptionofmy device will necessarily vary, I desire to emphasize the factthat various minor changes in details of construction," proportion and arrangement of parts inay'. be resorted to, when required, without s'acri-vj 'ficing any of the advantages ofjmy'inven tion, as defined in the appended claims.

Having thus fully described my invention,
