CAR-COUPLING.

Specification of Letters Patent.

Patented Dec. 22, 1914.

Application filed September 8, 1913. Serial No. 788,603.

T 0 all whom it may concern Be it known that l, GEORGE GRABANY, a sub ect of the King of Hungary, residing at Robins, in the county of Guernsey and State.

of Ohio, have invented certain new and useful Improvements in Car-Couplers, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to car couplers and has for its object, a device of such class, in

a manner as hereinafter set forth for automatically coupling a pair of cars together when the sills of the cars are brought in close proximity to each other and, to further provide a coupler with means, in a manner as hereinafter set forth, whereby when two cars are coupled, one can shift laterally relative to the other when rounding a curve;

Further objects are to provide a. car coupler which is comparatively simple in its construction and arrangement, automatically operated to coupling position, strong, durable, efficient and convenient in its use, readily attached to the sills of the car or draw-head, and comparatively inexpensive to manufacture.

With the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described, and illustrated in the accompanying drawings, but it is to be understood that change, variationsand modifications can be resorted to which fall within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views, Figure 1, is a side elevation of a car coupler in accordance with this invention showing the adaptation thereof in coupling a pair of cars'together, Fig. 2, is a longitudinal sectional view of the coupler showing the same applied to a pair of cars, Fig. 3, is a top plan view of the coupler, Figs. 4 and 5 are views similar to Figs. 1 and 2, but illustrating a modified form, Fig. 6, is a top plan view and Fig. 7 an end view of one of the elements of a form shown in Fig. 4.

Referring to Figs. 1, 2 and 3 of the drawings 8 denotes a draw-head carried by a car 9 and having each side at its forward end cut away to provide, when taken in connection, with side straps or bars 10, pockets 11. The bars or straps 10 are secured to the sides of the draw-head 8 and do not project to the outer terminus of said draw-head. Extending through the outer ends of the bars 10,

and also through the outer end of the drawhead 8 is a pivot bolt 12, which is secured in position by a nut 13.

The reference character 14 denotes the body portion of the hook element of the coupler and which has formed integral with its lower face, central thereof, the shank 15 of a hook 16. The shank 15 projects rearwardly with respect to the body portion 14 and is provided withan opening 17. The body portion 14, is suspended beneath the draw-head 8 through the medium of a pair of vertically disposed arms 18 which extend laterally into the pockets 11 and are mounted on the bolt 12.

The hook 16 is normally maintained in position to couple through the medium of a resilient member, as shown, consisting of acoiled spring 19 having one end extending through the opening 17 and its other end as at 20 anchored in the bottom of the drawhead 8. The draw-head is recessed as at 21 for the reception of a portion of the spring. The draw-head has its lower face furthermore provided with a pocket 22 in which is seated one end of a cushion element as illustrated a coil spring 23. The body portion 14 of the hook element of the coupler is provided with a pocket 24 in which is mounted the other end of the spring 23.

The latch element of the coupler consists of an arcuate body 25 having its rear face beveled as at 26 and said body is further more provided with rearwardly extending arms 27, which project between the sides of the draw-head 28 and the side straps 29 which are secured to the sides of the drawhead. Draw-head 28 is carried by the car 30. Extending through the straps 29 and draw head 30 is a retaining bolt 31 for the latch element of the coupler. The bolt 31 also extends through the arms 27 and is secured in position by the nut 32.

The outer face of the latch element is beveled so that the bill of the hook 16 will ride over the forward face of the latch ele ment and be strapped against the rear face 26, due to the action of the spring 19, under which conditions coupling elements are in position to couple the cars. The arcuate body 25 allows the car 30 to shift laterally with respect to the car 9 when rounding curves. Spring 19 will maintain the pocket drawings the latch element which is indicated by the reference character 33 is of the same construction as that shown in Figs. 1, 2 and 3 and under such conditions it is not necessary to describe the same. The hook element or member of the coupler consists of a depending yoke 34, which is pivotally mounted upon the bolt 35, carried by the draw head 36. The yoke 34 is provided with a depending bracket 37 in which is pivotally mounted the shank 38 of the hook 39. The pivot of the shank 38 is indicated as at 40 and extends through the bracket and into the yoke 34. Arranged within the bracket 37 are two pairs of coil springs 41, 42 the function of which is to normally maintain the shank 38 at right angles withrespect to the yoke 34. The upper face of shank is provided with a pocket 43 in which is arranged one end of a resilient element 42, the other end of the latter being anchored in the draw-head 36, as at 45. The function of the element 44 is to maintain the hook 39 in engagement with the latch element 33, the latter being carried by the draw head 46. Interposed between the draw-head 36 andw the yoke 34 is a cushioning element 47 in the form of a coil spring. When the shank 38 shifts upon its pivot 40, the shifting is, had against one of each pair of springs 41 or 42, depending upon which direction the shank shifts.

What I claim is A car coupler the combination with an arcuate latch element having beveled inner and outer faces and adapted for'suspension below the draw-head or car sill, of a spring controlled element-pivotally,mounted on the said draw-head and being suspended there below, the said hook element being formed with a broad bill adapted for engagement with the inner face of the latch element for coupling said elements together, and springs disposed between the draw-head and the said hook element and comprising a cushion ing means therefor and being adapted to tensioning said hook toward the said latch element.

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

GEORGE GRABANY.
