Specification of Letters Patent.

Patented Nov. 19, 1912.

, Application filed June so, 1910. Serial No. 569,743.

To all'whom it may concern:

Be it known that I, ELI I-I. JANNEY, a citizen of the United States, residingat Alexandria,in the county of Alexandria and State of Virginia, have invented new and useful Improvements in Car-Couplings, of

. of construction will be materially lessened.

In many of the couplings of the J anney or Master- Car Builders type now being made, the pivot of the coupling hook 1s 10- cated substantially on a line with the inside face of the locking jaw of the coupling hook when closed, and at a right angle to the longitudinal-axis of the draw bar. This l tioned construction, under the strain on the coupling hook, practically the entire transverse strain-and wear falls onthe pivot pin 3, and it is primarily to lessen this strain that my improved construction is designed.

In the accompanying drawing :.Figure-1 is a top plan view of the front end of the draw-head and coupling hook embodying my improved construction. Fig. 2 is an elevation of the front end of the draw head and coupling hook looking in the direction of the arrow A, Fig. 1. Fig. 3 is a detail top plan view of the front end of the coupling hook. Fig. 4 is a detail plan view of one ofthe draw-head lugs.

In the said drawing the reference numeral 1 denotes the draw-head, and 2 the usual coupling hook pivoted therein by means of the pivot pin 3, passing in the usual man-- ner through the upper and lower lugs 4' of the 'draw head. It'will be observed that the location of the pivot pin 3 with respect to the coupling hook 2 and-draw-head 1 is on a line' with the inside face of the locking jaw of the coupling hook taken at a right angle to the longitudinal axis of the drawhead. With the pin 3 so located the entire transverse strain is ordinarily imposed upon said pin, and the object of the present invention is to take up a part of this strain and to prevent wear on the coupling hook pin and the draw-head. This I accomplish by forming upon the upper and under sides of-the coupling hook 2 projections 5, and by recessing the lugs 4 of the draw-head at 6 to receive said projections 5, as shown, said recesses being long enough to permit the movement therein of the projections 5 from the open to the closed position of the coupling hook and being so located as to lie to the rear transversely of the pivot pin 3 when the coupling hook is closed, as shown.

By means of this construction I provide that the projections 5, when the coupling hook is in the closed position and a transverse strainis exerted thereon, shall bear against the vertical walls of the recesses 6 at 7 and 8, 1t being understood that under such a strain the line of-force on the pivotis such that the shoulders on the upper and lower sides of the coupling hook face pass to the rear of the center of the pivot of said coupling hook, whereby the vline of draft strain on said pivot 3 is through said shoulders, so that they aid said pivot in resi'sting the same by their contact with the lugs 4 of the draw-head, and thus render unnecessary the projections 5.

In myimproved construction both the rib 5 and the depression 6 lie above both the hub and the butting orrear bearing shoulder 9 of the coupling hook,'thus relieving said rib and depression from all but the transverse strains on the coupling. Having thus described my invention, what I claim as new and desire to secure by Letters Patent is In a car coupling, the combination with a draw-head, a coupling hook, and a removable pivot pin therefor, the center of said pin being located substantially on a line with the inner coupling face of the coupling hook, of an arc-shaped rib on the oouplin hook adapted to engage a, similarly shaped iepression in the draw-head, the two lying above both the hub and the bufiing or rear bearing shoulder of the coupling 10 hook, whereby they receive the transverse strains to protect the coupling hook pin therefrom.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.

ELI H. J ANNEY.
