BALLARD B. SMITH, OF RUSI-I RUN, WEST VIRGINIA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 576,233, dated February 2, 1897.

Application filed Tune 80, 1896.

To all whom, it may concern:

Be it known that I, BALLARD B. SMITH, a citizen of the United States of America, residing at Rush Run, in the county of Fayette and State of West Virginia, have invented certain new and useful Improvements in Car- Oouplings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of my invention is to provide an improved automatic cancoupling of the hookand-link type, which is more especially adapted for use in connection with mining-ears, the hook and link being so constructed and connected to their respective draw-bar that they will be maintained in a normally hori zontal position and will be capable of an upward swinging movement, the link being arran ged to project horizontally from the drawbar, while the hook is so shaped that a portion of the same will be positioned below the level of the link in order that when the cars come together the link will be lifted to be free to move over the end of the hook.

My invention consists in providing a car with a continuous draw-bar, to one end of which is connected the hook and to the other end the link, said draw-bar being bolted to the floor and transverse beams of the car.

The invention further consists in the construction and arrangement of the bumpers, between which the coupling device is located, said bumpers being practically a continuation of the fioor of the car.

The invention further consists in the construction and combination of the parts, as will be hereinafter fully set forth and claimed.

In the accompanying drawings, forming part of this specification, Figure 1 is a plan view of the coupling, the hook and link beshown in engagement with each other. Fig. 2 is a side elevation of the hook, the link being shown in section and elevated in dotted lines. Fig. 3 is a plan View of one of the cars. Fig. 4 is a longitudinal sectional view.

A designates the car-body, which is provided with bolsters of the usual type, to which Serial No. 597,634. (No model.)

is secured the floor A, said floor extending beyond the ends of the body to present projecting portions to a, serving as bumpers. Upon the floor is located a draw-bar B, which is bolted or otherwise secured to the door of the car. upon itself and cut away centrally to present loops or eyes 0 C, the terminal of the drawbar being extended to lie under the ends of the floor of the car. It will be noted that the part of the draw-bar between the eyes 0 provides bearings which serve to maintain the hook and link in a normally horizontal position, the said hook and link being constructed for this purpose, as hereinafter described.

D designates the link, which is made up of a single bar of metal bent or formed to present side members and a forward connecting portion, the rear ends being bent inward to engage the eyes 0, while the terminals are bent forwardly between said eyes to provide a secure connection, as well as to bear upon the part of the draw-bar between the eyes, for the purpose hereinbefore stated.

E designates the hook, which is also made up of a bar of metal shaped to form the hook proper and the ends bent to engage the eyes 0 and extend forward between the same in a manner similar to the link and for the same purpose. The hook proper is bent clownward, as shown, so as to locate the forward part thereof slightly below the plane of the link in its normal position. By this arrangement the link will ride upon the inclined portion of the hook and cause an automatic coupling of the cars when they come together.

The hook and link can be thrown back out of operative position by simply swinging the same back against the car-body or crosspiece thereof.

It will be noted that the bumpers extend sufficiently forward so that when the cars come together the hook nor the link will not contact with the ends of the draw-bar, and when the cars are coupled the usual swing or play will be allowed in rounding a curve, as is provided by the ordinary pin-and-chain coupling used upon cars of this character.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is

1. A coupling for mining-cars, comprising Each end of this draw-bar is bent a link and a hook, draw-bars having eyes by which the hook and link are connected thereto and a bearing-surface between said eyes, the hook and link being provided with portions which extend forward between the eyes of the draw-bar, substantially as shown and for the purpose set forth.

2. In a coupling for mining-cars, the combination, of the continuous draw-bar the ends of which are bent upon themselves or looped and cut away cent-rally to present eyes with a bearing-surface between; together with the hook and link-having their ends bent to engage the eyes and their terminals extended forward, substantially as shown and for the purpose set forth.

3. In a coupling for mining-cars, the combination of a continuous draw-bar having terminal portions bent upon themselves and cut away centrally to present eyes 0 O; to-

gether with a link the ends of which engage with the eyes C of the draw-bar, and a hook similarly connected to the other end of the draw-bar, substantially as shown and for the purpose set forth.

4. In a mining-oar, the combination, of the continuous draw-bar having its ends bent as shown, a hook and a link connected to said bent ends; and the floor of the car extended at its ends on each side of the coupling devices to provide bumpers a a, the said bumpers projecting sufficiently to prevent the hook and link from engaging with the ends of the draw-bar when the cars come together.

In testimony whereof I affix my signature in presence of two witnesses.

BALLARD R. SMITH.
