T all whom it may concern.-

Be it known that I, HENRY H. MARSHALL, a citizen of the United States, residing at Lincoln, in'the county of Lancaster-and State of Nebraska, have invented anew and useful.

Car-Coupling, of which the following isa specification.

The invention relates to improvements in car-couplings. l

The object of the present invention is to improve the construction of car-couplings,

more especially the means for attaching the same to cars, and to provide a simple, inexpensive, and efficient draft mechanism designed especially for use on passenger-coaches and sleeping-cars and capable of efiectively cushioning the longitudinal movement of the draw-head and draw-bar.

The invention consists in the construction and novel combination and arrangement of parts hereinafterfully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a plan view,

partly in section, of a portion of a car provided with a car-coupling constructed in accordance with this invention. Fig. 2 is a horizontal sectional View illustrating the manner of connecting the car-coupler to the-at- Like numerals of reference designate cor responding parts in both figures of'thedrawin s' l e ldesignates a draw-head provided with a shank or draw-bar 2 and connected; by par-jallel rods 3 with an attachmenteframe l, and

the said rods, which are designed to extend the entire length of thecardjf rom one draw; head to the other, are provided attheir ends 4o withslots 6,receiving'keys 7ofthe draw-head:

The draw-head is provided at its back at 0pposite sides of the shank or draw-bar 2 with sockets or recesses 8 for the reception of the ends of the draft-rods, which are enlarged and flattened, as clearly shown in Fig. 2. The

keys extend vertically through the draw-h ead,

and theymay be retained in place by any suitable means, being preferably provided at their upper ends with'heads and at their lower ends with suitable fastening devices.

The attachment-frame, which may be of any desired size, is composed of side bars,

by the continuous draft-rods.

and these sides 9, which are connected by a cross-piece 10, are provided with end sockets '11, receiving cushioning or buffer springs 13,

disposed on the rods and interposed between the draw: head and the attachment-frame.

These coiled springs, which may be of any 1 size and strength, are adapted to cushion the draw-head, the springs at both ends of the car operating simultaneously to cushion both of. the drawheads, which, are connected The sides of the draft-frame are provided with enlargements and have perforations for the reception of fastening devices 14 forsec uring them to the frame of a car,and the cross-piece 10 is secured to suitable enlargements 15 at the inner faces of the sides; but it may be formed integral with the sides or constructed in any other suitable manner. designed especially forsleeping-cars and passenger-coaches, and the ends of the sides having the sockets are arranged flush with the end sill of the car, which is preferably pro- The draft-frame is vided with a face-plate 16, plungers 17, and a cushioning-spring 18, constructed as set forthrin Patent No. 416,070, granted to me February 10, 1891. The cushioned face-plate and theplungers 17 are designed for use on vestibule=cars, as set forth insaid\patent.

The shank or draw-bar 2 of thecar-coupling is connected with'the cross-piece 10 by a tail-bolt l9,'- and-a cushioning-spring 20 is disposed on the tail-bolt and interposed between the cross-piece 10 and the shank or draw-ban. Thetail-bolt is secured to the shank or' draw bar by a pin or key 21, and its rear end is perforated for the reception 'of a similar pin or key' 22, located'back of the cross-piece 10.

The draft-rods are preferably mounted in longitudinally alined guide- openings 38 and 39 of the sides of the draft-frame; but they may be arranged in any other suitable manner, and I desire it to be understood that these and various other changes within the scope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

What is claimed isv 1. The combination of adraft-fr'ame provided with end sockets, a draw-head having a shank or draw-bar extending between the sides of the draft-frame and connected with the latter, longitudinal draft-bars connected directly to the draw-head atopposite sides of theshank or draw-bar,and cushioning-springs located at opposite sides of the shank or drawbar and arranged in the said sockets and interposed between the draft-frame and the draw-head, substantially as described.

2. The combination of a draft-frame, a draw-head having a shank or bar and provided at opposite sides of the same with recesses located at the back of the draw-head, draft-rods provided with slots or openings arranged in the recesses of the draw-head, keys mounted on the draw -head and passing through the slots or openings of the draftrods, and cushioning-springs interposed between the back of the draw-head and the draft-frame, substantially as described.

3. The combination of an attachment-frame provided at opposite sides with longitudinally-alined openings, draft-rods loosely arranged in the longitudinally-alined openings, a draw-head having a shank arranged between the sides of the draft-frame, the back of the draw-head being connected to the draftrods, and coiled springs disposed on the draftrods and interposed between the attachmentframe and the draw-head, substantially as described.

4. Thecoinbination ofanattaehment-frame having end sockets and provided with longitudinal openings, draft rods extending through the openings of the draft-frame and provided at their ends with slots, a draw-head provided at opposite sides with sockets receiving the ends of the draft-rods,keys mounted on the draw-head and passing through the slots of the rods, and springs arranged on the rods and seated in the sockets of the draftframe and engaging the back of the drawhead, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two Witnesses.

HENRY H. MARSHALL.
