CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 278,903, dated March 13, 1583.

Application filed January 25, 1883. (No model.)

To all whom it may concern Be itknown that I, JEREMIAH SHOWALTER, a citizen of the United States of America, residing at Okonoko, in the county of Hampshire and State of West Virginia, have invented certain new and useful Improvements in Gar-Couplings; and I do hereby declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others skilled in the art to which it appertaius to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in a device for automatiically coupling cars; and its object is to provide a means whereby the coupling-link will be guided into place automatically and the link will fall below the plane of the draw-bars, so that it will not be injured.

It has also for its object to provide a means whereby the coupling-pin will be dropped antomatically; and to this end my invention consists in providing the bumper or draw-head with a spring rock-shaft having an arm and sliding bolt, which rock-shaftis provided with a cam, whereby the link-guide support may be dropped so as to allow the link-guide to fall under the bumper before the cars come to gether.

My invention also consists insnpporting the coupling-pin upon a trip-lever having ai'orwardly-projecting pin which is operated by an arm attached to a spring rock-shaft, which arm is provided with a sliding bolt which releases the rock-shaft and allows the same to turn so as toraise the arm and release the coupling-pin.

- My invention also consists in providing acar-coupling with alink-guide which is held in position by a spring-catch which is released by a. spring-actuated rock-shaft provided with a cam and an arm carrying a sliding bolt and a trip-lever.

My invention also consists in providing the draw-head or bumper with a central upright having an opening in its upper end, through which passes a pin for the support of the coupling-pin, said supporting-pin being actu- 5o ated by a trip-lever which is released when the cars come together.

My invention also consists in providing the coupling-pin support with a. pivoted standard having a sIde-projecting arm and a spring which presses said arm forwardly,in combination with a spring rock-shaft and trippinglever.

My invention also consists in the combination and organization of the parts, as will be hereinafter set forth, and pointed out in the claims.

In the annexed drawings, which illustrate my invention, Figure 1 is a perspective view,

in which the parts are shown attached to a draw-head in position prior to coupling. Figs. 2 and 3 are longitudinal sections taken through the line a: a and 3 7 of Fig. 4. Fig. 4 is aplan view. Fig. 5 isa side view. Fig. 6 is a detailed perspective View of the standard, hav- 7o ing attached thereto a side arm and the coupling-pin supporting-pin. Fig. 7 is a detailed perspective view of the springcatch for holding the rock-shaft in position.

In the accompanying drawings, which illustrate my invention, A represents the bumper or draw-head, which is provided with a raised wall or portion, B, having side walls or brackets, O. This draw-head is also provided with a vertical standard, D, which, with the side brackets, O,forms bearings for the spring rockbars E and F, to which parts, hereinbeforc mentioned, the rock-bars are jOlll'llilled. To the forward part or" this draw-head A is pivoted a suitable link-guide, U, which consists 8 of a forwardly-projecting plate, 0, with raised and tapering sides, as shown. This linkguide is pivoted by the side arms, H, so as to embrace the sides of the draw-head, one

of said arms being longer than the other and beveled at its end, so as to engage in a notch provided on the latch 71, which latch has on its rear side a suitable spring, i. By means Attached to the outer end of the rock-shaft E, which is actuated by a spring attached to the lowest shaft, E, as will be hereinafter described,.is a cam.g, which, when the rockshaft is turned, will trip the spring-arm hand release the arm H of thelink-guide and allow the same to fall beneath the draw-head, so as to be out of the way when the cars come together.

Attached to the side brackets, O, of the central standard, D, is a rock-shaft, E. to which is rigidly attached an arm, I, which is bit'urcated at its outer endfor the reception of the upper end of the trip-lever J. This arm I projects through the rock-shaft so that its rear end will form a catch; or said catch may be formed on the rock-shaft, as shown at I in Fig. 3. The arm I is provided on its under side, near the point of attachment to the rockshaft E, with a bail in which slides a latch-bar, 1, which is of about the same length as the arm I, and is similarly bifurcated at its outer end. Within the bifurcated end of this arm I and latch-bar I is pivoted, as shown, the triplever J, which is curved so that its lower end will be on a line with the central portion of the draw-bar. It'desirable, this latch-bar may be provided with a suitable stop, a, which will limit its rearward play; and it is evident that the outer end of the arm I and latch-bar 1 will be united to each other by the upper end of the trip-lever J and the pivots which unite the parts. In the rear of this rockshaft, and bet-ween the side brackets andcentral standard, is pivoted a latch, K, as shown in Fig. 7,which has on its front surface a catch. This latch is pressed downwardly by a spring attached to the vertical wall B. The free end of this latch extends below the rock-shaft, as shown, and engages with the catch formed thereon.

Under the'rock-shaft E is a drum, E, which is provided at its end with a ratchct-wheel,f, and a pawl,f. To this drum E is attached a suitable spring, S, the opposite end of this spring being attached to the rock-shaft E after being coiled several times around the same.

By means of this spring the rock-shaft E is turned and the arm I thrown upward. Said spring may be tightened by adjusting or turning the drum E.

On the upper end of the vertical wall B is secured a suitable cushion, C, against which the arm 1 strikes when thrown upward.

The operation of this portion of my invention, which relates more especially to operating the link-guides, is as follows: When the cars approach each other the link is guided by the plate 6 into the opening in the draw-head, and the face of the adjacent bumper strikes against the trip-lever J, which forces the sliding bolt- I backward and releases the rock-bar E from the spring-catch. Said rock-bar, being turned by the spring, carries with it the arm I and the cam g, which is firmly secured to the rock-shaft, which cam strikes against the upper end of the catch it and releases the arm H, which allows the guide to fall under the drawhead.

Attached to the opposite side of the central standard, D, are two similarly-arranged shafts or rock-bars, with similar appendages to those hereinbefore described, for operating the linkguide, though the arms and sliding bar which project forwardly are of less length than those for operating the link-guides, and they operate in a similar manner when tripped. The central standard, 1), is cut away at its rear for the reception of the linkv K, as shown in Fig.

6, which link is pivoted atits lower part to the aforesaid standard, and is provided at its upper part with a pivoted forwardly-projecting pin, 70, which extends through the perforation in upper part of the standard D. This link K is provided at its rear with a spring, which keeps the same constantly thrown forward, and it is provided on its side with a projecting arm, it, against which the arm I strikes when the same is released.

The coupling-pin is provided at its upper portion with an eye, asshown in Figs. 1 and 2, which is placed over the pin prior to coupling the cars.

It will be noticed in this invention that the pivoted parts-that is, the catches K, as shown in Fig. 7, and the link K-are secured to the side and central standards by a central pivot, m, also that the levers I and l conver'ge t0- ward each other at their ends, and the triplevers, being bent as shown, bring the same forward of the coupling-pin and about on a line with the center of the draw-head.

The drum E, to which one end of the springs are attached, is provided with means where by the same may be tightened as necessary.

The general arrangement and construction of this invention being fully shown in the accompanying drawings, a further description of the parts which are simply duplications of those hereinbefore described it is believed is unnecessary, and I will only describe the operation of the pin-releasing devices, the operation of the link-operatingdeviccs having been heretofore described.

After the link-guide is released and the arm thrown backward, the link being guided in its receptacle in the draw-head, the arm being thrown upward, the bumper strikes against the trip-lever adjacent to the end of the drawhead, which causes the arm I to be thrown upward, which strikes against the arm 'n on the link K. which withdraws the pin from the eye in the coupling-pin and allows the same to fall, thus coupling the cars together.

Having thus described my invention. what I claim as new, and desire to secure by Letters Patent, is t 1. In a car coupling device, the draw-head provided with a raised rear wall, B, and side walls, 0, supportingrock-shaftsE F,andspringdrum E, in combination with a spring, F, and trip-lever J, spring-catches K, and means for re- ITO leasing" the link-guide, substantially as shown.
