sPEoIFIcATIoN forming part of Letters Patent No. 520,842, dated June 5, 1894.

Application filed raam 2e. 1894. sen-n No. 501,513. (No man.)

To all whom it may coz/werfe.-

Be it known that I, DANIEL BOYER, a citizen of the United States, residing at Cressona, in the county of Schuylkill and State'of Pennsylvania, have invented a new and useful Car-Coupling, of which the following is a specification.

This invention relates to that class of antomatic car couplings which embody a vertically-moving spring-actuated arrow-shaped draw-head, and the object of my invention is to provide a simple and improved car coupling of this class, which will possess advantages in point of convenience, inexpensiveness, ease and facility and safety in operation, effectiveness, durability, and general efficiency.

My invention consists in certain improvements in the construction, arrangement, and,

operation of parts, substantially as hereinafter described and particularly pointed out in the claims.

In the drawingsz-Fignre lis a perspective view of a car coupling embodying my improvements, the end of a box car being shown. Fig. 2 is a vertical longitudinal sectional view. Fig. 3 is a horizontal sectional view, on the line :1c-, Fig.. 2. Fig. 4i` is a bottom plan View, parts being broken away to show the interior construction. Fig. 5 is a perspective view, showing the parts of the draw-head detached. Fig. 6 is a detail perspective view, illustrating the operating devices on top the car. Fig. 7 is a perspective view showing the end of a flat car and illustrating detail modifications in the mechanism for controlling the operation of the draw-head.

Corresponding parts in all the figures are denoted by the same letters of reference.

Referring to the drawings, A designates the end of the car, upon the bottom, B, of which is provided a housing for the draw-head, consisting of downwardly-extending side pieces,

C C, having vertical shoulders, c, near their rear ends. The housing also comprises a rear crosspiece, D, and a bottom piece, E.

F designates the draw-head which comprises two parts, viz: a main or body portion, F, and a front pivoted portion, F2, the latter having an arrow-shaped projecting front end, F2, in the topof which may be formed a cut or recess, f, through which passes a vertical perforation, f in which works a vertical pin,

f 2, to adapt the draw-head for convenient connection with the ordinary pin and link coupling, when desired. The rear or body section F of the draw-head ts between the side pieces C C of the housing and is supported and inclosed within the latter. In the top of the section F is provided a recess, f3, eX- tending to the front end of the section, as shown, and in the rear vportion of this recess is accommodated the head, h, of a bolt, H, passing through an opening, f4, in the rear end of the section F and nutted or headed at its rear end, as shown at h. The bolt H thus has a free movable connection with the main section of the draw-head, and upon the rear projecting end of thebolt is mounted a rear plate, I, and a front plate, J, between which plates is provided a coiled spring, K, mounted upon the bolt. In the longitudinal movement of the draw-head, the spring K is compressed between the plates I and J, a free spring movement being eifected by the loose movable connection of the bolt H with the main section F of the draw-head. In the forward movement of the draw-head, the shoulders c c of the side pieces of the housing form a stop for the front plate J, while in the rearward movement of the drawhead the rear cross piece of the housing forms a stop, the longitudinal movement of the draw-head in either direction being thus limited. The recess f2 has the top portion of its rear wall preferablybeveled upwardlyand forwardly, as shown at f5, and is preferably provided with a forwardly inclined or beveled bottom, f6, to which is secured an upwardlyprojecting coiled spring, G, which bears against the rear tongue of the pivoted front section F2 of the draw-head and controls the vertical movement of said section. From the rear end of the front section F2 projects a tongue, F4, which is pivotally secured in the corresponding recess f3 of the main section F by a transverse pin or bolt, L. The rear edge of the tongue F4 against which the spring G bears is beveled downwardly and forwardly, as shown at f7, and the front edge of the section F is curved, as at f8 f2, to correspond to the inclined rear face, j9 fg, of the pivoted section F2. The draw-head thus comprises two parts or sections, the main or rear section F being snugly inclosed in the hous- IOO ing and having a spring-actuated longitudinal movement therein, while the front projecting section F2 is pivotally mounted upon and carried by the main section F and has a longitudinal movement therewith as well .as an independent spring-actuated vertical movement. The edges f8 and f9 of the respective sections abut together, as shown, and serve to limit the downward play of the front pivoted section F2.

To control the operation of the pivoted coupling section F2 of the draw-head, I provide a vertical moving rod, M, extending to the top of the car and having its lower end Working through an opening, m, in the bottom of the car and bearing against the tongue F4 of the pivoted section F2. The rod M may have a bearing in suitable brackets, O, and is provided near its lower end with a collar or shoulder, m', between which and the bottom of the car is mounted a coiled spring, P, the oflice of which spring is to retain the rod up in normal position. A plate, N, may be provided to receive wear occasioned by the action of the lower end of the spring P. To the top end of the rod M is pivotally connected a lever, Q, mounted in horizontal position over the top of the car upon a suitable bearing, q, above the top. The free end of this lever may be engaged by an approximately U-shaped crank, R, pivotally mounted on top the car and having a crank, r, at its end adapted to be engaged by the foot of the operator, to lock the mechanism in position.

To provide for controlling the operation of the coupling from the sides ot the car, a cross bar, S, is mounted upon the rod M above the shoulder m' and is adapted to bear against said shoulder, as shown. The ends, s s, of the cross bar S project at the sides of the car through guides or keepers T, and are adapted to be engaged by a tongue or projection, u, projecting from aplat-e, U, to lock the mechanism in position, a beveled edge, s', being preferably provided upon the cross piece S to facilitate this engagement.

When my improved coupling is employed upon iiat cars (see Fig. 7) the vertical rod M is shorter and is fixed or secured to the cross piece S, the latter being secured to the top of the rod and the collar or shoulder m' being dispensed with. In lieu of the plates U, I may employ a right angle pivoted catch, as shown at V, Fig. 7, for engaging the projecting end s of the cross bar S to lock the mechanism in position.

The rear face of the arrow-head F3 may be provided with vertically-disposed ridges or grooves, w and w respectively, adapted to be engaged by corresponding ridges or grooves in the arrow-head of the connecting drawhead, by which construction a locked connection is formed between the draw-heads so that relative movement or disengagement laterally is controlled.

The operation and advantages of my improved car coupling will be readily understood by those skilled in the art to which it appertains. The improved two-part drawhead has a free spring movement in its longitudinal play and the pivoted front section has also a vertical spring movement, which insures a positive and effective automatic connection.

By reason of its general construction and arrangement, my improved coupling is especially adapted for eiective use upon curves and for cars ot' varying heights.

It will be understood that metal, wood, or any other suitable material, may be employed in the construction of the respective parts of the coupling.

Having thus described my invention, I claim and desire to secure by Letters Patentl. An improved car coupling, comprising thehousing having the side pieces C provided with the shoulders c, the two-part draw-head embodying the rear or main section and the front pivoted section,the main section F being provided with a recess receiving a tongue upon the front pivoted section F2, the spring G provided in said recess, the bolt I-l, the plates Iand .Land the spring K,substantially as set forth.
