REENFORGEID l/VOOD BOX-CAR END.

Application filed January 29, 1919, Serial No. 273,751.

To all whom 2'25 may concern:

Be it known that I, VVTILLIAM H. MINER, acitizen of the United States, residing at Chazy, in the county of Clinton and State of New York, have invented a certain new and useful Improvement in Reenforced Wood Box-Car Ends, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in reenforced wood box car ends.

.As is well known, there are many thou sands of wood box cars now in service on the railroads of the United States and Canada which are of insuflicient strength, particularly in the end walls thereof, to withstand the heavy service now encountered. The ends are particularly subject to breakage and distortion because of the shifting of the load within the car which strikes the end Walls and either breaks the latter out entirely or disrupts them in such manner as to render further operation of the car unsafe until repairs are made.

Many attempts have been made heretofore toovercome the difiiculties above incicated and among other expedients employed, is the use of sheet steel or metal ends in lieu of the wood ends. The substitution of allmetal ends for the wood ends involves con siderable expense and labor and furthermore necessitates keeping the cars out of service for considerable periods of time. l/Vhe'n' cars are thus changed over to the allmetal ends, it is evident that, in addition to the expense and time lost, the value of the original wood ends is also lost.

The object of my invention is to provide a reinforcement for wood box car ends which can be applied to the wood ends without modification of the latter and so as to utilize the strength inherent in the wood ends; to provide a reinforcement which shall be easy of application involving minimum labor and time; and to provide a reinforcement so arranged that the strains are trans mitted to and partly absorbed by the end sills, end face plates and side walls of the car.

Renewed March 13, 1922. Serial No. 5 13,4553.

In the drawings forming a part of this specification, Figure 1 is an elevational view of the end wall of a wood box car showing my improvements in connection therewith. F 2 is an enlarged, horizontal, sectional vlew taken substantially on the line 22 of Fig. .1. Fig. 3 is a horizontal, sectional View upon an enlarged scale corresponding substantially to the section line 3.3 of Fig. 1. And Fig. 4 is a vertical, sectional view taken substantially on the line 44 of Fig. 1, being partly broken away in order to pre vent crowding of the drawing. In said drawings, the end wall of the car is shown as formed in the usual manner by means of vertical wood posts 1010, outer wood sheathing 11, inner wood sheathing 12. horizontal braces 13, end plate 14, and end sill 15. The side walls are formed in the usual manner and, as customary, include side plates 16 with the outer facia boards 1717. The roof is shown at 18 and the foot-boards at 19.

To reinforce the wood end without modification of the latter. I employ preferably two I-beams 2020, lower anchor brackets or castings 2121, intermediate clamping castings or brackets 2222, upper securing castings or brackets 2323, diagonal tension rods 242-1-,, tension rod anchoring brackets 25 25, and tie rods 26-26.

The I-beams 20, of which two are employed, are applied to the outer face of the end wall and in alinement with the usual intermediate vertical posts 1010. Each I-beam 20 extends from a point in line with the end sill 15 to a point in line with the end plate-14:. Each anchoring casting 21 at the bottom of the I-beams is formed with a socket 27 to receive the innermost flanges of the lt-beam and a portion of the web of the I-beam, as clearly indicated in Fig. 2. Each of said castings 21 also has a horizon tal shoulder 28 against which the bottom of the beam rests as shown in Fig. 1. Each casting 21 is formed with suitable flanges or ears perforated to accommodate a plurality of securing bolts indicated at 29, the latter passing through the outer sheathing of the end wall and the end sill 15, as shown most clearly in Fig. 4:. In this manner, it

is evident that the I-beams are secured to or with the end sill of the car underframe so that part of the load is transmitted to the end sill and underframe. 30 indicates the buffer block or deadwood which is applied on top of the castings 21 and which is, of course, located between the I-beams 20.

Each of the securing or clamping brackets 22 is located approximately midway of the height of its corresponding I-beam and, in actual practice, in alinement with the usual horizontal bracing beams 13 of the car end wall. Each of said clamping brackets 22 is provided with a suitable socket to receive the inner flanges of the I-beam and a portion of the web of the latter, the same as the brackets 21. The brackets 22 are slipped over the I-beams before the latter are applied, and the brackets 22 are held in position by means of bolts 31 which pass on opposite sides of the vertical posts 10 through the horizontal bracing beams 13.

The upper anchoring brackets 23 are socketed as indicated at 32 in Fig. 3, so as to slip over. the top ends of the I-beams, the sockets accommodating the inner flanges of the L beams and a portion of the web, the same as the other brackets 21 and 22. Each bracket 23 has, an upper horizontal wall 33 to fit against the top of the corresponding I-beam as shown in Fig. 1, the brackets 23 being secured to the end wall of the car and particularly to the end plate 14 by a plurality of bolts 3434. As will be evident, the brackets 21 and 23, when secured in position, prevent any vertical movement of the I- beams as well as prevent lateral movement of the latter in conjunction with the intermediate clamping brackets 22.

Each of the upper anchoring brackets 23 is formed with a laterally extended boss 134 having a diagonally arranged perforation 35 therein through which is extended one of the diagonal tension rods 24. The tension rods 24 pass through suitable perforations in the end wall of'the car at the top thereof and at their inner ends are extended through perforations in flanges 135 formed integrally with the rod anchor brackets 25, as shown in Fig.3. The anchor brackets 25 are bolted to the side walls of the car through the side plates 16 thereof as by bolts 36, the brackets -25 being located preferably several feet from the corner formed by the end and side wall of the car. As will be understood, nuts 37 are used on the ends of the rods 24 so that the latter may be tightened up in the proper manner.

In order to prevent possibility of lateral separation or spreading of the two I-beams, the tie rods 26 are employed, one near the top and one near the bottom of the I-beams as shown in Fig. 1. Each tie rod 26 is passed at its ends through suitable perforations in the webs of the I-beams and nuts 38 applied ares thereto on the inner and outer faces of the web as shown in Fig. 2.

From the preceding description, it is evident that the reinforcement which I have provided can be applied cheaply and in a comparatiyely short time without involving any changes in the structure of the end and side walls of the car other than, of, course, the boring-of the necessary holes for the securing bolts. Endwise pressure applied to the end wall of the car will be resisted by the wood structure itself and also by the I-beams which areplaced, broadly speaking,- under bending strains. This endwise pressure in turn is transmitted from the I-beams to the end sill and underframe of the car at the bottom and at the top to the end and side plates 14 and 16 so that the shocks are well distributed to all adjacent parts of the car. Obviously, the I-beams andtension and tie rods can be readily obtained generally from stock on hand in railroad car shops and the only special devices required are the relatively small and light anchoring and clamping castings.
