SIDE-SILL BRACKET.

Specification of Letters Iatent.

To all whom it may concern: Be it known that I, HARRY M. PITLAGER, a residing at St. have invented a certain new and useful Improvement in. Side-Sill Brackets, of which 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 I Figure 1 is a side elevation of a side sill bracket of my improved construction. Fig. 2 is a front elevational view of the bracket. Fig. 3 is atop plan View of the bracket with parts of the car underframe shown in dotted lines. Fig. 4 is a side elevation of a modified form of the bracket. Fig. 5 is'aplau I fied form of the bracket. 25

This invention relates generally to car construction and more particularly to a reinforcing and strengthening bracket utilized at the lower corners of the car body in conticularly designed for use in connection with nection with the underframe and the end frames.

In order to overcome the tendency of car bodies to telescope during collisions various structures have beendevised andare at present in general use, whichstructures includecast metal underframes, one-piece end frames and combined .double body bolsters and platforms. To further strengthen and reinforce the ends of car bodies so as to reduce to a minimum the tendency of said bodies to telescope during collisions l propose to provide strengthening and reinforcing members in the form of angle brackets that are applied to the side sills of the underframe and to attach to said angle brack- 'ets the lower side portions of the end frames. I y My improved cast metal brackets are parcast metal underframes and one-piece end frames of the type disclosed in Patents #917,716jdatedApril 6,1909 and #929,705

dated August 3, 1909 although it will be readily understood that the bracket can" be advantageously employedin'connection with I Theprincipal object of'my invention is to provide asimple, strong and rigid one-piece cast structure which can be readily applied to the exlsting types of underframes and end frames andwh'ich will provide asolid substantial brace for the lower'portion of the end frame, and which brace will eifectually resist severe end shocks and crushing stresses due to collisions and oppose all tendency of the cars to telescope, therebyaifordin'g maximumdegree of safety to. life and property.

Referring by numeralsto the construction illustrated in Figs. 1, 2 and 3, 1O designates thesidesillofthe underframe, '11 the end sill of. said end frame end frame. My improved bracket as shown comprises a plate 13 which is generally triand' 12 the one-piece angular in shape when viewed in side 'elevation and formed integral with'the edges of i this plate is an outwardly projecting mare ginal-fiange l4. ,Formed integral with and projecting inwardly from the heelor rear lower portion of the plate 13 is a horizontallv disposed" lug 15, which, when the bracket isapp'lied to the underfraine, bears directly against a shoulder 16 formed on top of the side 5111] of the underframe- The bracket is rigidly fixed to the side sill of the underframe' by means of rivets or likefass teningdevices 17 which pass through'the lower portionof the plate 13 and the corresponding portion of the side sill-10. When properly applied for use the base of the bracket rests directly upon a horizontally disposed flange 10 which projects outwardly from the lower portion of the side sill 10. The lower portion of the side member of the end framelQ bears directly against the front side of thebracket and thes'eengaging parts are rigidly fixed to one another by means of rivets or in any suitable manner. I c In the modified construction illustrated in Figs. 4, 5Iand6 the base of the bracket is cut I away along its lower outer edge, asdesig nated by' 18 in order to accommodate the horizontally disposed flange of an angle side sill 19, and which construction is utilized where combined double body bolster and platform castings form a part of the underframe and are united bycontinuous flang d i 10. I

side sills such as 19.

'end frame, of brackets positioned between In the modified construction illustrated in Figs. 7, 8 and 9 the marginal flange 14; is dispensed with at the base of the bracket and said base terminates a slight distance above the flange 10 of the underframe in order to accommodate an angle side sill 20 having an extra wide base flange. In this i construction the inwardly projecting bracket extends entirely across the lower portion of the bracket, as designated by 15 and this bracket bears directly upon and is rigidly fixed to the corresponding portion of the underframe. In this form of device integral strengthening webs 15 extend from the ends of the bracket or flange 15 upwardly along the front and rear edges of the main body portion of the bracket.

My improved reinforcing and strengthening bracket is preferably cast in a single piece so that it can be readily applied for use, and when properly combined with an underframe and end frame provides a very strong and comparatively light construction which unites with the end frame and resisting all end shocks and crushing stresses, thereby minimizing the tendency of telescoping of the cars due to collisions when said cars are running at high speed.

By the use of reinforcing brackets of my improved construction the tendency of the upper portion of an end frame to swing inwardly under crushing strains is resisted and the brackets themselves are rigidly supported upon the underframe by the engagement of the rear portions of the flanges or brackets 15 against the shoulders 16.

The bearing of the bracket or flange 15 directly on top of the side sill of the end frame and against the shoulder 16 removes all shearing strain from the rivets utilized in fastening the bracket to the underframe.

My improved brackets, while particularly designed for use in connection with cast metal underframes and cast metal end frames, can be advantageously employed in connection with built-up structures, and when combined with either integral or builtup structures provides a very strong, rigid construction which is anti-telescopic in effect for the reason that it effectually braces the lower side portions of the end framing against end shocks and crushing stresses.

It will be readily understood that minor changes in the size, form and construction of the various parts of my improved structure can be made and substituted for those herein shown and described without departing from the spirit of my invention, the scope of which is set forth in the appended claims.

I claim:

1. The combination with a car underframe having shoulders on its side sills and a car the lower side portions of the end frame and the shoulders on the side sills of the underframe.
