CAR-COUPLING.

- SPECIFICATION forming part of Letters Patent No. 416,187, dated December 3,1889;

Application filed June 26, 1889. Serial No. 315,640. (No model.)

To all whom it may concern:

Be it known that I, GEORGE V. SMILLIE, a citizen of the United States, and a resident of the city of Newark, Essex county, and State of New Jersey, have invented new and useful Improvements in Car-Couplers, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to car-couplers; and it consists, first, in the form and construction of the draw-head and of the hinged locking de vice, which latter is that part of the coupler adapted to engage and lock with the connecting-coupler, whereby the same will keep its proper position in the draw-head of thecoupler and in engagement with the connectingcoupler in case of the loss or breakage of the pivot or the coupling-pin, or both, and in other details of construction, to be referred to hereinafter.

The object of my invention is to provide a car-coupler of simple construction and of few parts, thereby rendering the same less liable to get out of order and at the same time possess the greatest strength and durability, and also of such construction that its locking or engaging jaw or arm will remain locked or connected with the engaging-coupler in case of loss or breakage of either the pivot or the coupling-pin, or both, theimportance of which will be readily understood by those skilled in the art.

Referring to the drawings, Figure 1 represents a top plan view showing two of my improved couplers in engagement; Fig. 2, a horizontal sectional view of the same; and Fig. 3, a top plan view showing a modification, to be referred to hereinafter.

In the drawings, A represents the d raw-bar; B, the draw-head, provided with two projecting arms or extensions 1) b, the latter being formed by a recess 1), cut into the front wall of the draw-head, for the admission of the lockingjaw of the engaging coupler, as clearly shown in the drawings. To one of said arms or extensions an S-shaped, or nearly so, locking device is hinged at or near its forward angle, as shown, the forward arm or extension c of which forms alockingjaw adapted to engage or look with a corresponding jaw in an engagingcoupler, as shown, and on its inner engaging-surface is slightly cut away or rounded, in'a manner, as shown, to allow the drawing points of the locking-jaws to operate on one another as a socketed hinged joint to avoid friction when rounding curves, &c.,' there being more or less slack between the jaws, as shown, the advantage of which will be readily understood by those skilled in the art, and the rear hookshaped arm 0 of said locking device extends and operates within a correspondingly-shaped opening or recess 6 located in the side of said draw-head B, as clearly shown, and is adapted to engage with the front wall of said opening or recess b when the forward extension or locking-jaw c is in a locked position with an engaging-coupler, to act as a supplementary or safety lock, in connection with the locking-pin, to hold the locking-jaw in engagement with its connecting-jaw in case of breakage of the pivot-pine, upon which said locking-arm is hinged, as 'will be readily understood by those skilled in the art. Said rear arm or extension 0 of the locking device C also forms a support for the lockingpin (represented at D) when the latter is raised from engagement with said locking device C at the forward end of the rear hook-. shaped extension or catch 0 at which point it is adapted to engage the latter, as clearly shown. .W'hen the locking-jaw c connects with an engaging-coupler, the locking-pin D prevents said rear arm 0 from sliding forward to uncouple the locking-jaw, and at the same time holds the said rear arm in its hooked position, with the forward wall of the opening or recess b in the draw-head,serving to relieve the pivot-pin e from a direct strain upon the same, and also, in case of breakage or other damage to the latter, said rear extension or catch engages the front wall of said opening I) and prevents the locking device from being pulled from its position in the draw-head B and the locking-jaw from disconnecting with its engaging-jaw; or, in case of the loss or breakage of both the pivot and coupling pin, the size and shape of said opening or recess b is such as to allow the locking device C to be pulled a'little forward of its pivot-point, and the rear arm or hook c of the same to move slightly forward, and thus be prevented from moving or sliding therefrom, as will appear obvious to those skilled in the art. In some instances 1 also provide a pawl F, adapted to be pivoted Within a slot or recess in the wall of the drawhead, as shown in Fig. 3, adapted to engage with notches c located in the said rear e.\'- tension 0 of the locking device to lock and hold said device in a locked position, (in ad dition to the means already described) in connection with the locking-pin, or, in lieu of the latter, in case of the loss or breakage of the same, as will be readily understood by those skilled in the art. The said pawl 1 may be used regularly or be used only in cases of necessity, and when not desired for use may be hooked back out of position for engagement with the said extension 0 by a hook or other suitable means and be operatedthat is, be caused to engage or disengage with the said arm-by hand or by other suitable means.

The locking-pin Dis adapted to be open ated by a lever and connections, substantially as shown and described in a patent granted to me April 10, 1887, No. 361,460, or by other suitable means.

Having thus set forth my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a car-eouplen'the combination, with a draw-head provided with two arms or extension s, and with an openin or recess 5 therein, of an S-shaped, or nearly so, locking device pivoted to one of said arms or extensions, the forward arm of which locking device forms a locking-jaw for connection with an engagingcoupler, and the rear hook-shaped arm of which projects into and is adapted to engage the front wall of the said opening or recess W, in a manner and for the purpose set forth, and a locking-pin adapted to engage the said locking device, substantially as described, and for the purpose set forth.

2. In a car-coupler, the combination, with a draw-head provided with two arms or projections, of an S-shaped locking device hinged to one of said arms or extensions, provided with a front arm forming the lockingjaw, and a rear arm or extension 0 the latter being provided with notches therein, and a pawl adapted to engage the notches in said arm 0 of said locking device to lock the latter, substantially as described, and for the purpose set forth.

3. The combination, in a ear-coupler, of a draw-head provided with a pivoted locking device substantially in form of an S, adapted to form connection with counterparts or projections, with which such draw-bar is provided, and retain such connection in the event of the breakage or undue removal of the pivot or locking-pin, or both, in a manner substantially as described, and for the purpose set forth.
