DRAwBnn FOR MINE cans.

Application flier-Jane 10'; 1925. seriarno. "easel,

To all whom it may concern.

Be it known that I, CHARILn's a citizen of the United States,- residing at construction for mine cars of'the typ w are run into a rotary dump for emptying the car. In adumping device of the above typein which a car goes into acage and the cage is rotated to invert the car the car is often wrecked as the drawbars and shackles are twisted and often broken'th'ereby rendering cars useless, and involving great time and expense in the operation of unloadinga mine car;

It'is an object of the' intention to provide a drawbar of simpleconstructi'on and inexpensive to manufacture, which will permit a car upon which it is applied to be freely rotated ,to dump the same when Coupled with other cars forming a train.

' Referring to the accompanying drawings which are made a part hereof and on which similar reference characters indicate similar Figure 1 is a side elevation of my device, Figure 2, a bottom plan view,

Figure 3, an end elevation, Figure 4:, a perspective of one "of the end boxing's or bearings, and I Figure 5, a perspective of the coupling; As shown in the drawings the invention comprises a car'body l0 having a floor 11 supported by wheels 12 on axles 18 mounted in journal boxes or bearings 14. The car body is also preferably provided with a swinging end gate 15.

or boxings 16 are provided, one at each end of the car body in the center thereof supported between body braces or reinforcing elements 17 and 18 above and below the floor 11 of the car. The braces 17 extend upward and conform to the body of the car and reinforce the same while the braces 18 extend merely transversely beneath the floor. Bolts 19 extending through the floor clamp the braces 17 and 18 together. a

A drawbar 20-is supported in the boxings or housings 16, said drawbar being formed of a continuous rod or bar and having an opening in its end for reception of a con-:

Housing elements pling member; Also I pr'eferably' provide the drawbar witha co1lar21 adapted to bear housing or boxing 16 is preferably formed of upper and lower sections adapted to be against the outer end of the housing 16. The 7 secured together by bolts so that'they may be easily removed if such isdesirable. The

inner ends of the housings are'providedwith recesses in whichis mounted afcasing '23" for the drawbar; This casing is of strong construction and maintains the housing-tile ments 16 in "proper spaced relation From the foregoing it will be seenthat the car I body is free to rotate about the drawbar as an axis'and force applied to'the drz'twbar at one end of the car will-be'qual'ly distr'ibuted between both of the boxings 16. Thecasing 23 is clamped directly between the centrally arranged body braces 17 and 18 and the supporting elements 16 for said casing are also secured in a similar manner.

Couplings are providedconsisting of an odd number of links, preferably one or three, with a clevis at each end thereof. As

shown in Figure 5 my coupling consists of links 23", each end link beingprovided with a clevis24 having a 'p1n25 with an enlarged moved, said pin being adapted to pass through the endof the draw bar.

housing elements secured between spaced no In the above construction astring of cars pairs of braces, and a drawbar extending the length of said body through said housing elements, substantially as set forth.

2. The combination in a mine car, of a floor, braces extending across said floor on opposite sides thereof in opposed relation, housing elements secured between spaced pairs of braces, a casing having one end nested in each of said spaced housing elements and serving as a reinforcement to maintain them in spaced relation, and a drawbar extending the length of said body through said housing elements and casing and having a stop adjacent the outer side of said housing for preventing the longitudinal movement of said drawbar through said casing, substantially as set forth.

3. The combination in a mine car, ofa body, a floor for said body, a brace adjacent each end of said body extending across said floor, a second brace at each end of said body secured on the opposite side of the floor, securing elements extending through said floor and connecting each pair of braces, a housing secured between each pair of braces intermediate their ends, and a drawbar mounted in said housings and extending throughout the length of the car, substantially as; set forth.

4. The combination in a mine car, of a body, a floor for said body, a brace adjacent each end of said body extending across said floor, a second brace at each end of said body secured on the opposite side of the floor, securing elements extending through said floor andconnecting each pair of braces, a housing secured between each pair of braces intermediate their ends, a drawbar mounted in said housings and extending throughout the length of the car, and a casing for said drawbar supported by said housings between the same, substantially as set forth.

5. The combination in a mine car, of a body, a floor for said body, a brace adjacent each end of said body extending across said floor, a second brace ateach end of said body secured on the opposite side.

ing the movement of said drawbar through said housings, substantially as set forth.

6. The combination in a mine car, of a floor, a housing adjacent each end of said floor and having flanges on its top and bottom forming a channel between the same, a casing having one end nested in each of said housings, a drawbar extending throughout the length of said car through said housings and having a collar adjacent each end, braces secured across saidfloor" on opposite sides thereof between said channels, and an additional pair of opposed braces securedacross said floor and clamping said casing in position, substantially as set forth. 7

7. The combination in a mine car, of a floor, a housing adjacent each ,end of said floor and having flanges on its top and bottom forming a channel between the same, said housing being longitudinally divided,

a casing having one end nested. in each of said housings, a drawbar extending throughout the length of said car through said housings and having a collar adja-,

cent each end, braces secured across said floor on opposite sides thereof between said channels, and an additional pair of opposed braces secured across said floor and clamp ing said casing in position said floor being extended beyond the ends ofsaid drawbar to form bumpers, substantially as set forth.

In witness whereof,I have hereunto set my hand and seal at Balkan, Kentucky this 5 day of June,A. D. nineteen hundred and twenty-five. i i
