MINEFCAR.

Leraar?.

Speccation of Letters Patent.

Patented Dec. 2e, i911.

Application led October 17, 1910. -Serial No. 587,363.

clare the following to be a full, clear, and

exact description ot' the invention, such as will enable others skilled in the art to which itappertains to make and use the-same. v

My invention relates to buffers for railway vehicles, and more especially to mine cars, and its'principal object is to provide a combinedbuffer-block and draw-head suitable for such cars, which consists in the provision of adevice of economical and rigid construction for receiving the bufling shocks and pulling strains.

As illustratedin the drawings, the centersill of. `the car consists of a timber or other member extending beyond the ends of the car. I rovide these extending'ends of the center-sill of the car with metallic buffers, preferably of cast'steel, to prevent their being battered. The buffer-block has a clevis which forms a reception of the coupling links, and has a hole for the coupling pin, so that it also serves as the draw-head.

In order to relieve the frame of the car socket vfor the Y i from practically all tensile stresses, I luse a ing part of the specification,

draft-rod which extends-between the two coupling pins, having eyes in the ends thereof registering with those of the coupling block, as will be hereinafter more fully described and particularly pointed 4out in the 'appended claims.

Referring to the sheet of continuous drawings form- 'in which like characters of reference indicate like parts throughout the views z-Figure 1 is a side elevation of a mine car embodying my invention. Fig. 2 is a' top pla-n View of my improved buffer-block, also showing the centensill and draftfrod in position.- Figs. 3 and 4t are respectively a side elevation and an end elevation of the same. Fig. 5 is a transverse section taken on the line V'V of Fig. 2 and Fig. 6 is a longitudinal section taken on the line VI-V of Fig. 2.

Referring to the drawings, the numeral 1 designates the center sill of the car, which, in the drawings, is illustrated. as a single timber extending'beyondthe ends of the car,

although this is not absolutely necessary, as

the center sills might be made of more than one piece of timber, or they might be o1' metal. Buffer-blocks 2 preferably of cast steel, are mounted on the extended ends of the sill 1 and are constructed with a head member 3 having upper and lower rearwardly extending integral flanges 4f and 5 which 'embrace the upper and lower sides of theends of the 'center-sill. A draft-rod 6 rests upon the upper side of the center-sill y and' is continuous throughout the length of the car, relieving the center-sill of the major portion of the tensile stresses to which the car is subjected. The ends of the draft-rod pass under jan offset 7 inthe upper flange member et of the buffer-blocks and are secured thereto by means of bolts 8 which pass through the member L1,'the draft-rod 6, the center-sill l and a tie-rod 9, which extends under the centersill and acts as a cross-sill to tie the car structure together. The centei-sill 'and draft-rod are preferably secured together at intervals, so that the rod also reinforces the sill when the latter receives compressive forces. A clevis member l0 integral with the upper part of the bufferblock forms a socket 11 for the reception of the coupling links 12 cessive cars in a train. also has a hole' 13 for lthe reception of a coupling'pin 1li which 4registers with the which connects suc- This clevis member eyes 15 in the ends of the draft-rods 6, and

holes 1G and 17 in the center-sill and the bottom frame 5 of the buffer-blocks 2. The buffer-blocks 2 areV further secured to the center-sill, bymeansY of bolts 18 which pass through holes oneither side of the top flange il, thebcenter sill 1,' and thebottom flange 5,

as will be clearly seen by referring to the drawings. I

Although IV have shown and described my invention in considerable detail, I do -not wish to be limited to the exact and specific details set forth, but may use such substitutions, modifications, orequivalents there'- of, as are embraced within the scope of my invention, or as pointed out in the claims.

What I .claim as my invention and desire to secure by Letters Patent, is

. l. In a car, a center-sill extendingfbeyond the ends of the car, a buffer-blockmounted on either end of said sill, a clevis member formed integral with the buffer-block and extending above 4the same and a draft-rod extending `between the vbuffer-blocks and adapted to act as a draw bar.

2. A combined buer-block and drew-` head, comprising a head member adapted to receive impact of colliding vehicles, rearwardly 'extending flanges, a clevis member integral with one of the enges, and a draftrod secured to the center-Sill and theV said flange of the bull'er-bloek.

3. In a car, a center-sill, abuffer-block mounted on the end of said sill, a clevis member on vthe buferblock, said clevis member forming a, socket for a, couplinglink and a coupling pin extending through the clevis member and a portion of the buffer-block. w v I 5. In a car, ya center-sill, buffer-blocks l blocks and mounted on the ends of the Said sill,- a cievis member on each buffer-block, said clevis member forming a socket for a, couplinglink, e draft-rod connecting the buffera, coupling pin extending through the clevis and the lower lia-nge of the buffer-block.

6. In a' mine car, the combination of a draw bar attached to the top of the cerv bottom -and having a hole for a, coupling pin near its projectlng end, a-fbumper comprising a topl plate divided to receive the drew bar centrally, Vand a buffer portion formed as an integral part of said bumper,v and member, the draft-rod,

fitted with a hole for 'the coupling pin in'v correspondence to the hole in the end of the draw bar. Y'
