BRAKE SHOE. APPLICATION P ILED APR.28, 1908.

' Patented Mar. 16,1909.

George LM 'auvemto'c GEORGE MALDEN BEARD, or HANOVER, PENNSYLVANIA.

BRAKE-SHOE.

Application filed April 28, 1908. 'Serial No. 429,663.

-To all whom it may concern:

Be it known that I, GEORGE MALDEN BEARD, a citizen of the United States, residing at Hanover, in the county of York and.

State of Pennsylvania, have invented a new and useful Brake-Shoe, of which the following is a specification. 1 I

The invention relates to improvements in Make shoes.

The object of the present invention is to improve the construction of brake shoes,

and to provide a simple and comparatively inexpensive one, designed for use on locomotives and various kinds of cars and possess- -b mgmcreased wearingquahties and having means for preventln it from breaking.

Withthese and ot 161 objects in View, the

invention consists in the construction and novel combination of described, Illustrated drawing,

parts hereinafter fully in the accompanying ous changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing F-Figure l is a erspective view of a brake shoe, constructed ance with this inveiition. Fig. 2 is a front elevation of the same. Fig. 3 1s a transverse sec'ti'enal view. Fig. 4 is a detail perspective view of the reinforcin or strengthening bar. and the connecting yo e.

Like numerals of reference designate corresponding parts in -all the figuresof the drawin brake shoes for locomotives, railway cars, etc. In order to strengthen the shoe and prevent the same from breaking or cracking when applied to a locomotive, car, or the like, the cast iron body is reinforced by a pair of wrought iron or malleable bars or members 2, extending lon itudinally of the brake shoe and having t e body ortion The bars or mem ers 2, which are of a width corresponding with the thickness of the body portion of the brake shoe, have their front and rear edges exposed at the front and back of the brake shoe. The bars or members are bowed laterally from each other and are curved longitudi- Specificationof Letters Patent.

-nally to conform to the configuration of the brake shoe. The'front edges of the ba1s' 'or members are concavely curved and their rear edges are convexly curved.

The terminals 3 of the barsor members are- 'fitted together, and are provided at their outer convex faces with projecting lugs or flanges 3, which are adaptedto rcinforce the extreme ends of the brake shoe ,to prevent the same frombreaking ofi'. flanges 3 which are of a thickness substantially the same as that of the bars or membars, are arranged at the median lines of the v are or members and have stra1gh-t' outer edges, and are provlded w th inner tapering portions, as clearly illustrated in Fig; 4 of the drawing. The side faces of the lugs or flanges are arranged in planes" substantially at right angles to 'the'planes of the inner and outerside faces of the bars or memberslf The said bars or members are connected at an intermediate point by;a yoke 4, consisting of parallel sides and a connecting transverse portion. The inner or front terminals 5 of" the sides are bent laterally to form transverse lugs, which extend through slots 6'01 the bars 01' members. The slotfsfi are'located near the rear edges of the bars or members at points intermediate of the-ends ofthe same, and the lugs project beyond theouter faces of the said bars or members and are embedded in the body of the brake shoe. The, yoke, which projects rearwardly from the body of the brake shoe, forms an eye for the attachment of brake mechanism (not shown), and the sides of the eyes are reinforced by opposite bosses or enlargements 7. In casting t e brake shoe, a small core is placed in the yoke to prevent the eye from being filled with cast iron, and the bars or members are provided at intervals with openings 2 to permit thecast metal to flow through the bars or members. Those portions of the cast metal at the inner and outer faces of the bars or members are united at intervals by the portions extending through the openings 2. j

' The brake shoe is providedat its rear face with projecting terminal stop flanges 8 and is equip ed with recessed lugs or portions 9 to inter t with the brake head. The yoke connects the reinforcin bars or members and facilitates the assem ling of the parts in the mold. I

Having thus fully described my mventlon,

' These lugs or or members being of a width corresponding to the thickness of the brake shoe and having their front and rear side edges ex osed at the front and rear faces of the said ody, and a yoke connecting the bars or members at points between the said front and rear side edges and partially embedded in the cast metal body portion. 2. A brake shoe including a cast metal body, and reinforcing bars or members embedded in the body and bowed laterally and body,

having their terminals fitted together.

3. A brake shoe including a cast metal body, and reinforcing bars or members embedded in the body and bowed laterally and having their terminals fitted together, said bars or members being of a width corresponding to the thickness 0 the brake shoe and extending entirely through the same and exposed at the front and rear faces thereof.

4. A brake shoe including a cast metal longitudinal reinforcing bars or members embedded in the body and provided between their ends with slots, and a yoke connecting the said bars or members and having its sides embedded in the body and provided with terminal lugs fitted in the slots of the said bars or members.

'5. A brake shoe including" a cast metal body portion, reinforcing bars or members embedded in the body portion and extending longitudinally thereof and provided between yided at its ends with laterally their side edges with opposite slots, and a yoke connecting the side bars or members and having its terminals projecting outwardly and extendin through the slots of the. said bars or mem ers and embedded in the cast metal body portion.

6.-A brake shoe including a cast metal body portion, a longitudinal reinforcing bar or member of a width. corresponding to the thickness of the brake shoe and having its front and rear side edges exposed at the front and rear faces of the body and proprojecting lugs or flanges.

7. A brake shoe including a cast metal body. portion, and reinforcing bars or members embedded in the body and-bowed longitudinally and having their terminals fitted together, said bars or members being provided at their outer sides with projecting terminal lugs or flanges arranged to reinforce the extreme end portions of the brake shoe.

'8. A brake shoe including a' cast metal body portion, and reinforcing bars or members embedded in the body and bowed longitudinally and having their terminals fitted together, said bars or members being provided at their outer sides with projecting lugs 01' flanges having their side faces arranged in planes substantially at right angles to the side faces of the bars or members.

In testimony, that I claim the foregoing as my own, I have hereto afi ixed my signature in the presence of two witnesses.
