CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 336,322, dated February 16, 1886.

' Application filed August 12, 1895. Serial No. 174,198. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES MYRoN INGER- soLL, of Summit Hill, in the county of Carbon and State of Pennsylvania, have invented a new and useful Iniprovementin Car-Couplings, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is aside elevation of one of my improved car-couplings shown uncoupled. Fig. 2 is a plan view of one part of the same, part of the link being broken away. Fig. 3 is a front elevation of a part of the same. Fig. 4 is a sectional side elevation of a part of the same. Fi 5 is a plan View of the coupling bar or link.

The object of this invention is to provide car-couplings constructed in such a manner that they will couple automatically when the ears are run together, and can be readily uncoupled,and which shall be simple in construction, strong, durable, and not liable to get out of order.

The invention consists in the construction and combination of various parts of the carcoupling, as will be hereinafter fully described and then claimed.

A represents the draw-heads, the mouths of which are made hoppershaped, as shown in Figs. 3 and 4, and indicated in dotted lines in Fig. 1. The shanks of the draw-heads A are slotted longitudinally and horizontally, to allow the ends of the coupling-bar B to have a free lateral movement, and the height of the said slots are made enough greater than the thickness of the coupling-bar B to allow the ends of the said coupling-bar B to have the necessary vertical play.

0 are the coupling-pins, which pass down through holes in the shanks of the draw-heads -A and through slots in the end parts of the coupling-bar B. The upper ends of the coupling-pins-O are pivoted to latches D at a little distance from their rear ends, so that the said pins will be raised and lowered by the up and down movements of the said latches. The latches D are pivoted at their rear ends to lugs formed upon or secured to the upper sides of the shanks of the draw-heads A, and

their forward ends extend nearly to the forward ends of the said draw-heads.

Upon the lower sides of the forward ends of the latches D are formed downward pro jections D, the inner edges of which are concaved, and their outer edges are convexed, giving to the said projections a hook form, as shown in Figs. 1 and 4.

The projections D of the latches D work in slots in the upper and lower parts of the draw-heads A, and the said latches D are made to move up and down in vertical planes by keepers E, attached to the upper sides of the said draw-heads, and are held down by V-shapcd springs F, which are secured at or near their angles to the rear parts of the said latches D, with their lower arms resting upon the upper sides of the said latches, and with the ends of their upper arms passing through the upper parts of the keepers E, and bearing against the bends of the said keepers. \Vith this construction, when two cars are run together, the entering end of the coupling-bar B strikes against the convexed forward edge of the projection D, and raises it and the latch D, and pin Opasses in beneath the lower ends of the said projection and pin until they drop through the slot in the said couplingbar B. The coupling-barB is made with tapered ends, as shown in Figs 1 and 4, and the said ends are made solid for such a distance that the ends of the projections D will rest upon the said ends until the said ends have passed beneath the lower ends of the coupling-pins G, which then rest upon the said solid ends until they slide off into the slots of the said coupling-bars, and the cars are coupled,the draft-strain coming wholly upon the couplingpins 0.

The center of the coupling-bar B is made solid, to give it the necessary strength, and the middle part of the said bar is widened and has the ends of the said widened part beveled, to correspond with the flare of the mouths of the d1aw-heads, so that the distance to which the coupling-bar enters the draw-heads will be limited by thesaid widened part of the coupling-bar coming in contact with the inner surface of the draw-heads.

Upon the pivoted rear end of each latch D can be formed, or to it can be rigidly attached, an arm, G, to serve as a foot-lever for raising the latch D to uncouple the cars, or an arm, H, to receive a chain connected with a lever pivoted to the front of the car-body; or to the forward end of the latch D can be pivoted the forward end of a lever, I, the middle part of which is pivoted to a standard, J, attached to the shank of the draw-head; or to the forward end of the latch D can be attached an eyebolt. K, to receiveachain connected with the top of the car-body, or to serve as a handle for raising the said latch and'uncoupling the cars.

A hole, L, is formed through the forward part of each draw-head A,to receive an ordinary coupling-pin, M, when it is necessary to" couple a car provided with my improved coupling with a car provided withthe ordinary pin-and-link coupling. The coupling-pin M is connected wilh the draw-head A byashort chain, N, so that it cannot be lost, and when not required for use is inserted in keepers 0, attached to the side of the draw-head A. c When it is desired that cars may be run together without coupling, the latch D and pin 0 are secured in a raised position by a pin, 1?, inserted in a hole formed in the keeper E. The pin 1? is connected with the draw-head A by a short chain, Q, to keep it from being lost, and when not requ red for use is inserted in keepers R, attached to the side of the drawhead A.

Having thus fully described my inventioml claim as new and desire to secure by Letters Patent- 7 1. In a car-coupling, the combination, with the draw-head A, the coupling-pin G, and the coupling-bar B, of the latch D, carrying the said coupling-pin, and provided with a hookshape downward projection, D, the keeper E, to guide the said latch, and the spring F, to hold the latch down to its place, substantially as herein shown and described, whereby the cars will be coupled automatically when run together, as set forth. r

2. In a car-coupling, thecombination, with the,draw-head A,'the latch D, carrying the coupling-pin O, the guide-keeper E, and the spring F, of the arm G, substantially as herein shown and'described, whereby the said latch and coupling-pin can be readily raised to uncouple the cars, as set forth.

3. In a car-coupling, the coupling-bar B, made, substantially as herein shown and described, with solid tapered ends, with a solid center, and with its middle partwidened and beveled at the ends of the said widened mid- 55 die part, substantially as herein shown ands;
