SAMUEL BURGESS, OF VINOENNES, INDIANA, ASSIGNOR OF ONE-HALF TO THORNTON IVILLIAMS, OF OLIVET, MICHIGAN.

CAR-CCU PLER.

SPECIFICATION forming part of. Letters Patent No. 394,755, dated December 18, 1888.

Application filed September 13, 1838. Serial No. 285,298. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL BURGESS, a citizen of the United States of America, residing at Vincennes, in the county of Knox and State of Indiana, have invented certain new and useful Improvements in Car-Couplers; andI do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in car-couplers; and it consists in the novel construction and combination of the parts thereof, as will be more fully hereinafter described and claimed.

1 have illustrated my improved coupler in the accompanyingdrawings,wherein like letters of reference are employed to designate similar parts in the several views, and in which Figure 1 is a perspective view of a part of.

a car with myimproved coupler applied thereto, and Fig. 2 is a sectional elevation thereof.

A indicates the head, chambered and provided with coupling-pin holes and with a top slot, a. The head A is formed on the outer end of draw-bar A having a recess, A, in the top thereof.

On top of draw-head A at each side of the recess A, journal-boxes O are attached, in which a transverse rod or shaft, O, has bearing, and upon this shaft 0'' a disk, 0 having a semicircular grooved periphery, is eccentrically mounted. The ends of said shaft 0 have hand-wheels O fixed thereon, and adjacent to the draw-bar a gear-wheel, C is also mounted on said shaft. The recess A in draw-bar A allows the disk C to have free movement, as shown in Fig. 2.

To a lug or ear, I), on the rear part of the draw-bar A under the car, the rear end of a longitudinal bar, B, is attached, which passes through a slot, Z1 in the end of the car and up over the disk 0 engaging with the semicircular groove thereof. The front end of said rod B has an angle-iron, b, secured thereto,through the horizontal member of which the pin P passes and is supported thereby, the head 19 of said pin resting on the top surface of the horizontal member of the said angleiron. Attached to said rod B, in rear of the head A, is a spring, S, which is secured at its lower end to the draw-bar.

In rear of the head A and to one edge of the bar A an angularly-bent bracketarm, E, is attached, having an upper rolled end to form a bearing. Passing through said upper rolled end and a lug, 6, formed with the adjacent side of the bar A is avertical shaft, E,which extends to the top of the car and has ahandwheel, E fixed thereon. The said shaft E is also provided with a worm, IE at its lower end, which meshes with gear -wheel O" on shaft 0.

In operation, by turning one of the handwheels 0 situated at the side of the car, the disk C is raised, as shown in Fig. 1, raising the rod B and pin P. \Vhen said disk is over its dead center, it is sustained as shown. After the link enters the head, the hand-wheel O is slightly revolved to turn the disk 0 slightly to one side of its dead-center, and the retractile effort of the spring S pulls said rod B down and forces the pin through the link and thereby couples. In operating the shaft O byhand-wheel E on shaft E from the top of the car the worm E revolves gear Ciwhen the motion is similar as when operating the coupler through hand-wheel O hen the shaft O is revolved, the gear C slightly raises the shaft E through its connection with the worm E as will be readily understood by skilled mechanics.

My improved coupler embodies simplicity and effectiveness, and its use prevents injury and loss of life to train-men.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a car-coupler, the combination of the draw-bar having a recess therein and slot or groove in the top surface of the head thereof, a longitudinal rod or bar extending over the top surface of the draw bar and head and carrying the coupling-pin at its forward end, and a grooved disk eccentrically mounted on a tmnsverse shaft upon which the rod or bar has direct bearing and is actuated thereby to raise the eoupling-pin, substantially as described.

2. In a ear-eou 'iier, the combination of the draw-bar having a reeess therein and slot or groove in the top surfaee oli' thehead thereof, a longitudinal rod orbar extending over the top surface oi. the draw bar and head, having an angle-iron on the front end thereoftor holding the eoupiingpin, a grooved disk eeeentriealb mounted on a transverse o jierating-shatft with which said rod or bar is in direet engagement and is aetuated thereby to raise the eoupIing-pin, and a (-oiled springattaehed to said bar or rod and to the draw-bar,

substantiaih as described.

ii. in a (2t]'(()ll} )i(l, the eombinatiou oi the draw bar and head, the longitudinai rod attaehed at its rear end to said bar and carrying the coupling-pin at its front end, a transverse operating-shatt having an eeeentrieallvmounted diskavhetd thereon with which the rod engages, a gtmr-wheei, a spring attached to said rod and draw-bar, and a \ertieai shaft having a worm thereon engaging the gear on the transverse shaft, sulistantiaiiy as de scribed.

4., In a ear-coupler, the eombination of the draw-bar A2 provided with a recess, A, and having head A, with a groove, (0, a 1-o(1,]- attached at its rear end to a lug or cal-,1), on the draw-bar and having an angle-iron, Z), on its front end carrying the coupling-pin, the spring S, attaehed to said. rod 1;, the transverse shaft 0, having bearing in boxes U on the dra\v-bar, and a disk, (,iwith. a grooved pm riphery, eeetmtriez'dly mounted on said shaft, operated by ham'i-ivheeis, a gear, (F, on said shaft, a braeket-arm, IQ, and lug e, seeured to the d raw-bar, and a vertieal sha l't, E, nniiunted in said arm E and hige,having a worm thereon meshing with the gear (1" on shaft (1, and a top operating halal-whee], substantially as (iOSOi'iiHiti.
