BRAKE-SHOE ANCHOR.

Application and Jul. 29,1896. seinro. 597,507. CN'omodel.)

To all whom it may concern.-

Be it known that I, HENRY O. Wrnnmnson, a. citizen of the United States, residing at Michigan City, in the county oi. La. Ports and State of Indians, have invented certain new and useful Improvements in Brake-Shoe Anchors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled 'in the art to which it appertnins to make and use the same.

Myinvention relates to a, novel construction in what I term a brakeshoe anchor for cartrucks, the object being to provide a device of this description from which the brake-shoes depend, which is secured to a. part of the truck which is practically immovable with relation to the wheels; and it consists in the features of construction hereinafter fully described and claimed.

In the accompanying drawings, illustrating my invention, Figure l is a top plan view of oneside of a. truck provided with a brake-shoe anchor constructed in accordance with my invention. Fig. 2 is adetail top plan view of a brake-shoe anchor constructed in accordance with my invention. Fig. 3 is an end elevation of the same. Fig. 4 is a side elevation of the same.-

In cartrucks it is desirable that the brakeshoes should always retain their positions with relation to the truck and wheels, so that no matter how many jolts the wheels are subjected to the same will be communicated to the brake-shoes and prevent them from engaging thc treads of the 'wheels higher or lower, according to the load or unevenness in the rails; To this end,'therefor'e, I provide what I term a. brake-shoe anchor, consist ing of a plate A, provided with openings 1 and 2 at its ends, throughwhich the column or transom-casting bolts 3 are ads. ted to pass,

by means of which said anchor is preferably secured to the truck at its middleportion. Said plate A is provided with longitndinal ribs or flanges 4 and transverse flanges 5 adjacent said enings 1 and'2, between which the heads 0 the column-bolts 3 are held against rotation when said plate is secured by means thereof. Said plate A is also provided with a downwsrdl -extending flange 6 on its inner edge, which s ada ted to snags the inner edge of the upper are -ba,r 7. id flanges are continued inwardly from said plate A and flan e 6 and form parallel arms 8, which extend ownwardly on each side of the bolster 9 and are provided at their ends with parallel outwardly-extending projections 1Q, between which the brake-shoe hangers 11 are pivoted by means of bolts 12, passing through openings in said projections 10 and through the eyes of said broke-shoe hangers 11. The brake-shoes 1 3 are mounted upon the hooks of the brake-shoe hangers 11 by moons of eyes 14 on the brake-heads, to which said brake-shoes are removebly secured.

Owing to the fact that the arch-bars of the truck are rigid with the car-axle boxes, it will be obvious that any vertical movements of the wheels will be communicated to the brakeshoes in the same degree and thus hold said parts vertically rigid with relation to each other. In consequence of the relative vertical rigidity of the wheels and brake-shoes I an enabled to so operate the latter that their contact-faces will always remain parallel with relation to the trends of the wheels they ongage.

My construction is also cheap, simple, and durable and easily repaired.

I claim as my invention- 1. A brake-shoe anchor comprising a plate adopted to be secured to the upper arch-bar of the oar-truck, and provided with inwardlyextending arms having means at their ends Iorsecuring the brake-shoe hangers thei-eto' 2. A brake-shoe anchor comprising a plate provided with openings to receive column or transom-costing bolts by means of which it is secured to the car-truck, a downwardly-extending flange on said plate adapted to enga e the edge of the upper arch-bar of the true arms on said piste, and projections onfthef ends of said arms to which the brake sh e hangers are pivoted.

3. A brake-shoe anchor comprising a plate provided with openings to receive column, or

transom-cesting bolts by means of which it is In fix m Bi m wpag l r mm in mm am M two witmm. y W m f a F a I r tmmmmumwm; and. luwwllyW I JUI'MMWW 5 lug anus nu ma ,late carrying u-ojemloas Witnesses:
