CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 438,717, dated October 21, 1890.

Application filed March 18, 1890.

To all whom it may concern:

Be it known that I, BYRON D. TABOR, a citizen of Wilson, in the county of Niagara and State of New York, have invented certain new and useful Improvements in Oar-Couplers; and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appert-ains to make and use the same.

My invention relates to an improvement in car-couplers, and more particularly to such as are peculiarly applicable for coupling freightcars, the object of the invention being to produce a car-coupler which shall be of simple construction, easy of manipulation, and effective in operation.

A further object is to construct a car-coupler in such manner that the coupling of the cars may be rendered automatic.

A further object is to so construct a carcoupler that the same may be effectually locked when the cars are coupled together.

Vith these objects in View the invention consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of a portion of the platforms of two cars partly broken away and having my improved coupler applied thereto. Fig. 2 is a side elevation. Fig. 3 is a separate View of one of the draw-heads. Fig. 4 is a View of a vmodificationl Figs. 5 and 6 are views of certain details.

A A represent the platforms of two cars, to the under face of each of which a draw-barB is attached. The draw-bar B is held in position by means of a bracket a, which is passed around said draw-bar and secured at its ends to the platform of the car, the draw-barbeing adapted to have a free movement through this bracket, and the stem l) of the draw-bar is passed through a perforated bracket c on the under face of the platform A. A spring d is made to encircle the stem b and bears at one end against the draw-bar and at the other Serial No. 344,334. (No model.)

against the bracket c and at its other end against a disk d2 at the free end of the stemb. Thus it will be seen the draw-bar Bis yieldingly attached to the platform of the car.

At the free end of the draw-bar my irnproved draw-head C is located, and this drawhead may be either made integral with the draw-bar or it may be made separate and adapted to be attached to an ordinary drawbar. One wall e of the draw-head O is made flat, having a V-shaped inwardly-projecting flange D at its outer extremity. The wall e of the draw-head inclines outwardly and forwardly from the inner end of the wall c and terminates at a point diametrically opposite the fiange D and parallel with the wall e. In other words, the draw-head comprises two jaws e e', the jaw e being made straight or flat and provided at its free extremity with a V-shaped or tapering Iiange D. Projecting upwardly from the rear end of the jaw e is a lug f, to which is pivotally connected an L- shaped lever E, which lever is composed of two arms g g. The inner face of the arm g is made fiat and extends downwardly from its pivotal connection with the lug f parallel with the outer fiat face of the jaw c. The arm g is provided at a point between its ends with a lug h, which lug when the parts are in position is adapted to bear against the fiat face of a pin t', passing through perforations j in the cross-head when such pin is used as hereinafter explained.

The draw-head on one of the cars to be coupled is preferably made separate from the draw-bar and adapted to have a slight lateral movement; or, if desired, both drawheads may be made detachable. When the draw-head is made separate, it is provided with a rearwardly-proj ecting shankj, adapted to enter an elongated socket in the end of the draw-bar, said draw-head being connected to the draw-bar by means of a pin J2 passing through the draw-bar and a perforation in the shank J. The draw-head may, if desired, be connected with the ordinary draw-head, as shown in Fig. 1. The weight of thel rearwardly-extending arm g of the L-shaped lever E tends to cause the arm g to normally lie diagonally across the outer face of the jaw e, and is adapted to be drawn rearwardly and IOO made to assume a vertical position by means hereinafter to be described.

Assuming now that the arm g of each coupler is in its normal position, when two couplers are brought together t-he free ends of t-he jaws e will come into contact with the arms g of the lever E and force said arms rearwardly. Simultaneously with this action the inclined outer faces of the flanges D will come into contact, and the jaw e of each drawhead be thereby guided into the respective draw-heads. When the ange D of the jaws e shall have passed each other, said jaws will engage the inclined faces of the jaws e', and the jaws e be thus made to approach each other. The arm g of the lever E will now swing by gravity between the jaw e of one draw-head and the jaw e of the other drawhead. Th us it will be seen that the two drawheads will be automatically connected and effectually locked together. When it is desired to uncouple the cars, the arms g of the lever E will be withdrawn, when the engagement of the inner inclined faces of the flanges D will cause the jaws e e to separate and be thus set free from each other.

A car-coupler constructed as above described is exceedingly simple and sure and eective in operation.

Should it be desired to connect my improved draw-head to a draw-head of ordinary construction, a link F will be employed. This link will preferably be made as shown in Fig. 4, having a head 7a and a shank 7c. The shank lt is adapted to be inserted into an ordinary draw-head, and is provided with an elongated slot Z to receive a coupling-pin 7a4, whereby the link is connected to the drawhead. The head 7a of the link F is provided at its rear end with an inclined face 7a2, adapted to engage the ange D of my improved draw-head, and the head of the link beyond the inclined face 7a2 is provided with a perforation 7e3 at right angles to the inclined slot Z. To couple the link F to my improved draw-head, the pin z' is passed horizontally through the perforations in the head and perforation k3 of the link F. The head of the pin 'a' is cnt away to produce fiat faces m n, against which thelug h ofthe arm gis adapted to rest. Thus it will be seen the pin will be prevented from turning by the engagement of the arln g with the face of the head of the bolt, and said bolt will be prevented from working loose or of endwise movement by engagement of the arm g with the fiat end n of the pin t'.

To manipulate the L-shaped levers E, the mechanism `now to be described will be employed. The rear end of the arm g of lever E is bifurcated to form short arms o, and each arm o is bifurcated. Located between the arms o is a grooved cam-block G, having laterally-projecting arms p, which pass between the bifurcated ends of the arms o, in which they are retained by pins 2J. In this manner the cam-block G is pivotally supported at the rear extremity of the arm g of the lever E. The free ends of the lateral arms p are provided with loops or eyes p2, to which are pivotally connected the hooked ends of two rods II. The rods H extend laterally to points in proximity to, or, if desired, beyond, the sides of thc cars, and are revolubly supported near their free ends by means of hangers I, suspended from the platform of the car. These hangers I may be braced by means of brace-rods I', extending from the platform of the car to the hanger. At the free ends of the rods H handles I2 are provided, by means of which to operate said rods. A chain or cord J is connected at one end to one end of the cam-block G and at the other end to the platform of the car. Now when the cars are coupled and it is desired that they be uncoupled it is simply necessary to rotate the rods II of each car from either side of the car. By this operation the cam-blocks G will be rotated and the chain or cord J be wound upon said blocks in the grooves thereof. Then the chains or cords J are wound upon the cam-blocks, the rear ends of the arms g of levers E will be elevated, and the arms g of said levers will be withdrawn from between the jaws e c of the respective drawheads, when said draw-heads will be allowed to separate, as above explained.

It will be noticed that it is impossible to couple two draw-heads together as long as the levers E are withdrawn, so that when it is desired to couple cars the levers E will be permitted to assume their normal rearward positions.

It may be desirable in some cases to provide means by which to operate the rods H from the top of the car. In such case a reel K will be provided at the free end of said rod, to which one end of two chains K is attached. The other ends of said chains are passed through suitable brackets on the car and terminate at the top thereof. One of the chains is normally wound upon the reel K, so that by operating the other chain said rod may be rotated in one direction. By this means the rods II may be alternately rotated in reverse directions.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
