ful Improvements in End Reinforcements for BOX-Cars, of which the following is a specification.

My invention relates to the provision of a metallic reinforcement for the end walls of a railway box car, particularly for a box car largely constructed of wood but which may have metal draft sills and metal striking or buffer blocks, or equivalent structures; and a -primary object of the invention is to provide a reinforcement fol` cars of this type comprising bars extending 'up the end walls of the car employed in conjunction with an end plate. reinforcing structure, buffer blocks or striking castings i and truss rods running the length of the car or other anchoring means, these elements being united together and the striking block being rigidly connected with the draft sills as is the universal practice in car underframe construction, so that the elements of the reinforcing and rigidifying system, thus provided, for the body of the car will strengthen and fortify the car body against cargo thrusts, weaving strains and other forces and pressure tending to weaken and destroy the car body. As the invention is intended to supply a reinforcement for the repair of old cars as well as a construction to be used in' `he building of new cars, the embodiment s own. in the drawing hereof involves a diagonal arrangement of the end wall reinforcing bars adapted for cars having truss rods not in line with the end posts; and it is a further object of the invention to provide an'arrangement of parts which can be adapted, by sllght changes, to various relative ositions of the truss rods and end posts; t e deviation from the vertical of.

proved constructions, arrangements and del vices to be hereinafter described and claimed for carrying out the above stated objects and such other incidental objects as will appear from the following description of a typical embodiment of the invention.

In the drawings annexed hereto, which show this embodiment,

'Figure 1 is a view, in elevation, of the body of a railway boX car.

Fig. 2 is a sectional plan on line 2-2 of Fig. 1.` Fig. 3 is a broken longitudinal sectional view of the car showing both ends thereof. Fig. 4 is a view, in perspective, of the end plate brace, and

Fig. 5 is a detail section on Fig. 1.

4Like characters of referencedesignate like parts in the several figures of the. drawings. Referring to the drawings, 10 indicates the end sill of the car (the corresponding parts in Fig. 3 at opposite ends of the car are given the same reference numerals), 11 the endplate, 12, 12 the end posts, 13, 1 the diagonal end braces, 14, 14 the end girths, 15 the end sheathing, and 16, 16 the side plates, the construction and arrangement of these parts being common to railway box cars of this general type. As a part of its line 5-5 of under frame the car is provided with chan'-- nel bar draft sills 17, 17 and with'buffer tlon as a beam supporting in partvthe body ofthe car and taking the thrust of the couplers against the striking castings in the usual manner. The coupler shank is indicated in outline at 21, being supported by a carry iron 22 secured to the bu er plates by tous 23.-

The car is provided with two truss rods 24, 24 which extend the length of the car, passing through bosses 25 formed on the buffer plates and being anchored' thereto by nuts 26. To reinforce4 the end wall of the car I rovide two reinforcing bars 27, at sachen of the car. These members are preferably Z bars.. They are secured at their upper ends to the end plate 11 by bolts 28, to the u per 'rth 14 by bolts 29, to the endv posts 12 y bo ts 30, to the diagonal rods 24 above mentioned, the flange 32 of the Z bar attached to the car wall intervening, in each case, between the end sheathing of the car and the buffer plate, as shown in Fig. 5', so that the truss rod on this side o f the car will pass through this flange. In order to rigidify the end plate 11 an angular brace 33 (Figf4) is secured to the inner side of the end plate by the bolts 28-above referred to, these bolts passing through the middle section 34 of the brace. The ends 35 of the brace are secured by bolts 36 to the side plates of the car. By this arrangement the 'stresses on the reinforcing bars `27 are transmitted through the brace 33 to the side plates ofthe car.

A reinforcing structure consisting of the elements above noted in the arrangement as described, provides a strong, light and relatively inexpensive expedient for strengthening and rigidifying the entire body of a railway box car of wood construction and thereby checking the action of those de structive forces, such as the thrust of shifting cargoes, weaving stresses, and the like, which are constantly at work while a vbox car is in service and which, unless effectively checked, materially shorten the life of the car. The Z-bar end braces at each end of the car are anchored to the under frame by means of the buii'er block, which is preferably but not necessarily a casting, and which, by bearing against the outstanding webs of the Zv-bars, and against the flanges thereof which lie along lthe sheathing,

' keeps the Z-bars from distortion and from being torn away from theirattachment to the under frame. The upper ends of the Z-bars are anchored tothe roof brace 33 through the end plate of the car so that there are provided unitary reinforcements for the end of the car which rigidify the entire superstructure.

This application is a continuation of my co-pending application Serial No. 86,402, filed March 24, 1916 (now Patent 1,282,568, granted October 22, 1918, reissued as No. 14,588 February 4, 1919).

I claim:

1. A reinforcement for the end wall of a railway box car comprising, in combination with the end plate, side plates, striking block and truss rods of the car: a pair of end braces on the outside of the end wall of the car and an end plate bracing structure withwall of the car extending diagonally from top to bottom thereof and attached to said end posts and also to said diagonal end braces, the lower ends of said end braces being anchored to said striking block, and an end plate bracing structure within the car secured to the end plate and side plates thereof to which the upperextremities of said end braces are connected.

n 3. A reinforcement for the end wall of a railway box car comprising, in combination with the end plate, side plates' and. striking block of the car: a pair of metal end braces Zeshaped'in cross section on the outside of the end wall of the car extending from the under frame to the roof frame of the car and converging toward their upper extremities, the lower extremities of which are anchored to the under frame by .said striking block, and an end plate bracing structure on the inside ofthe car comprising diagonal members extending from the center portion of the end plate to the side plates, to which structure the upper ends ofthe braces are rigidly anchored.

4. A reinforcement for a railway box car comprising in combination with the wooden end wall of the car: a pair of end wall bra-ces on the outside of the c ar extending from the roof frame to the under frame and converging toward their upper ends, atransverse element spacing the lower ends of the lbraces apart and anchoring them to the unlar in cross section on the outside of the car extending from the roof frame to the sill and converging toward their upper ends, a strikin block arranged between the lower ends o said end braces inthe angle between the webs thereof for anchoring the end wall braces to the end sill, and a roof frame bracing structure connecting the upper portion of the end wall of the car to the sidewalls to which the upper extremities of the end` wall braces are rigidly secured.
