DRAFT DEVICE FOR GARS OR OTHERVEHICLES.

SPECIFICATION forming partv of Letters Patent No. 553,438, dated January 21, 1896.

Application filed October l, 1895. Serial No. 564,254. (No model.)

To all whom t may concern:

Be it known that I, JAMES H. TURBUsH, of New York city, in the county and State of New York, have invented a new and useful Improvement in Draft Devices for Cars or other Vehicles, of which the following is a full, clear, and exact description.

My invention relates to supports especially adapted for sustaining the inward and outward thrust of the draw-bars of car-couplers, and the object of this invention is to provide a support simple, durable and economic and capable of convenient attachment to any car or like vehicle, which supports will be rigid and constitute travelers upon which the followers of the draw-bar or like draft device may have movement and upon which they will be sustained, the supports heilig of such nature and so arranged as to relieve the conning strap or tie for the springs from the severe strain which under the ordinary construction they must necessarily sustain.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims..

Reference is to be had to the accompanying drawings, forming a part of lthis speciiication, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a longitudinal section through a portion of the bottom of a car, illustrating the device in side elevation. Fig. 2 is a bottom plan view of the device and a portion of the bottom of the car; and Fig. 3 is a detail side elevation of one of the followers of the drawbar.

In carrying out the invention two main supports or brackets A are employed. The brackets are of like construction, and each preferably consists of an upper horizontal member 10, extending over the end sill a of the car and along the top of one of the longitudinal beams cd, a front vertical member 11, which is carried downward at the front of the end sill a predetermined distance below the same, and an upwardly-arched mem ber 12 engaging with the aforesaid beam a at or near the bottom, being connected with the upper member 10 by bolts 13, passed through both of these members and through said longitudinal beam a', the rear end of the arched member being provided with an upwardly or inwardly extending or angular member 14:, the upper section whereof is also connected with the longitudinal beam a and the upper member 10 of the support by means of bolts 15 or their equivalents. These supports or brackets A are placed one at each side of the center of the car, as shown in Fig. 2, or one at each side of the draw-bar B of the coupler C.

The extreme lower members of each support 0r bracket are provided with openings 15, the openings in each support or bracketbeing in longitudinal alignment. A bolt D is passed through all of the openings of each support or bracket, being provided at eacli end with a lock-nut 16 and a jam-nut 17, the lock-nuts engaging with the vertical end surfaces of the brackets or supports. At each side of the center of each bolt an enlarged threaded surface 18 is provided, each surface being adapted to receivea lock-nut 19. rlwo followers 2O are held to slide on the said bolts between the intermediate lock-nuts 19. Each follower is therefore provided with an opening 21 at each end, of greater diameter than the diameter of the bolt, and each follower has furthermore a central recess 22 made in its top and in its bottom edge to receive the strap or yoke 23 which is attached to the drawbar and which confines the spring 21 on the said bar, the forward follower abutting, as usual, against a shoulder on the draw-bar, and the rear follower having bearing against therear end of the strap, the spring being between the two followers. If in practice it is found desirable, the spring 24 may be omitted from the draw-bar and be placed one around each of the bolts between the followers. Thus it will be observed that when the draw-bar is forced inward or outward, compressing the spring 21, the strap 23 is relieved from the strain which it ordinarily has to sustain, the said strain being received and sustained by the supports A and their bolts D. It will be observed that the bolts D, while specifically such, are essentially and more broadly rods.

Having thus described my invention, I claim as new and desire to secure by Letters Patenty 1. In a draft device for cars and other vehicles, brackets or supports adapted for attachment to the under portion of the car or vehicle, having arched lower ends, the brackets being arranged side by side, abolt extending longitudinally through each bracket, followers having sliding movement on the said bolt, and means, substantially as described, for limiting the movement of the followers in a forwardly orin a rearwardly direction, as and for the purpose specified.

2.- In a draft device for cars, vehicles and the like, the combination, with supports or brackets adapted for attachment to a car or vehicle and having an arched lower end, bolts passed through the arched lower ends of the brackets, being secured in position thereon, adjusting nuts located at each side of the center of each bolt, followers held to slide upon the bolts between the inner nuts, a spring intervening the followers, and a drawbar .arranged to slide the followers on the said bolts when pressed inward or drawn outward, as and for the purpose specified.

3. Abracket for use as herein described, the saine consisting of a horizontal upperv portion bent downwardly at its forward end to form a forward portion transverse to the longitudinal upper portion, the lower end of the forward portion being arched and the bracket being thence extended rearward and formed with a second and rear arch longitudinallyT aligned with the first arch and the terminal of the bracket being bent up over the second and rear arch, substantially as described.

4. Ina draft apparatus, the combination of two brackets adapted to be held longitudinally with the; car, each of said brackets havin g two depending portions, a rod supported in the depending portions of each bracket, perforated follower plates receiving the rods in their perforations and movable on the rods and adapted to have connection with the draw bar, the follower plates being below the brackets and a spring for actuating the follower plates, substantially as described.

5. A bracket for uses herein described, the same consisting of a horizontal upper portion bent downwardly at its forward end to form a forward portion transverse to the longitudinal upper portion, the lower end of the forward portion being arched and the bracket being thence extended rearward and parallel with the horizontal upper portion and finally downward to form a second arch, said second arch being approximately longitudinally aligned with the irst arch, substantially as described. Y

6. In a draft apparatus, the combination of two brackets adapted to extend longitudinally with the vehicle to which they are to be attached, each bracket having two depending portions, rods respectively supported by the depending portions and longitudinally below the brackets, two follower plates slidably carried by the rods and out of contact with the brackets, and a spring for actuating the follower plates, the follower plates being capable of connection with the drawbar, substantially as described.
