The body of the lever C, when the draw- The front edges of the draw-head A are head is in position on a car-frame, as shown 50 flared to allow of the free introduction of the in Fig. '7, projects toward the car front wall G, and is connected loosely at its inner terminal 0 with an upright rod I, that extends to the car-roof for manipulation therefrom.

In service when two approaching drawheads having the improvements thereon are to be coupled the link B, of usual form, isheld projected from one draw-head by the pin Z), which is adjusted, as shown in Fig. 1, on the right-hand draw-head, the engagement of said pin with the web 9 of the draw-head and the end of the link B on its upper side holding the link projected, as its body lies upon the lower shoulder c of the draw-head A when such an adjustment is effected. The impingement of the projecting end of the link B on a pendent pin 1) of the draw-head to be coupled swings said pin rearwardly until it slides over the link end and falls into locked connection with the shoulders c and link end, providing the lever O is prostrate, as shown in Fig. 2. By providing the elongated hole n in the lever-head forits engagement with the f ulcrumbolt 92 the adj ustment of the pin end, as shown in Fig. 1, to engage a link end is permitted, and when coupled with a link the draft strain upon the latter will slide the pins b, so as to impinge on the shoulders 0, thus avoiding the necessity for a link of more than ordinary length to effect an attachment of two cars automatically.

When cars having the improvement are to be disconnected, the simple elevation of one of the levers C will draw the pin 19 into the positionshown at the left side of Fig. l and allow the link B to be freely Withdrawn from the draw-head A, which can be'effecte'd by a manipulation of the lever directly or through the rod I, as may be most convenient.

Strength, simplicity, practicability, and etficiency in service are claimed as features pertaining to this device, which will couple cars of the same or diiferent heights from the track equally well.

In the ears e opposite grooves e are formed of a proper depth laterally in the inner faces of said ears to receive the body of an ordinary coupling-pin, and in the lower wall of the draw-head A a circular hole 6 that aligns with the grooves, is formed.

The provision of the grooved ears and apertured lower draw-head wall-is for the purpose of allowing an ordinary cylindrical couplingpin to be used it the pin b and lever G should be. disabled or broken off by accident, this provision converting the improved draw-head into one of the usual style as far as connection with others is considered.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent 7 1. The combination, with aforwardly-chambered draw-head having a flared front end and a top and bottom shoulder within the throat of said chamber and also slotted above to align with spaced ear-s thereon, of a pendent locking-pin and a lever longitudinally slotted and pivoted therein between the ears to which the pin is jointed, substantially as set forth. I r

2. The combination, with a forwardly-chambered draw-head having a flared front end, two opposite aligning shoulders formed above and below in the throat of the draw-head chamber, a slot longitudinally extended from the shoulders rearward in the top wall of the draw-head chamber, leaving a transverse web therein, and two spaced ears laterally perforated to receive a fulcrum-bolt and located in alignment with the sides of the slot, of a lever having a cam-rounded head and ears on one side to pivotally engage the upper end of a pendent locking-pin and further provided with an elongated hole for engagement with the'fulcrum-boltin the ears, said hole-extending in the direction of length of the lever, a

locking-pin, and means to manipulate the lever from the roof of a car, substantially as set forth.
