COUPLING FOR RAI LWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 295,186, dated March 18, 1884.

Application filed October 15, 1883.

To all whom it may concern.-

Be it kn own that I, ALBERT K. MANSFIELD, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Safety-Couplers for RailroacLG-ars, of which the following is a specification.

My invention relates to an improvement in the apparatus for guiding the link when making acoupling, the object being to decrease the danger of accident to train-men. I attain this object by the mechanism illustrated inthe accompanying drawings, in which' Figure l is a longitudinal section through the drawhar and crosssection through the end sill of the car. Fig. 2 is an end elevation of the same; Fig. 3. a horizontal sectionthrough the drawhar, and Fig. 4: a longitudinal section through the same.

Thesame letters refer to the same parts throughout the several views.

The draw-bar G is supplied with a lifting lever, B A, in two pieces, the part A lying in arecess of the drawbar. Thehub of the piece B is fitted to turn in a hole in the side of the 'drawbar, and. the fulcrum end ot'A is fitted to the hub of B. A trip-tongue, E, is also fitted inside the draw-bar, turning free on a center at its lower end. The end'sill, M, ofthe car has a lil'tingshai't, H, hung in the bearings I I I I, and having an arin near its center, which is connected by a chain, F, to the free end of the arm B of the lever B A. The lifting-shaft is bent at its ends to form the operating-handles H H.

L L are heifer-blocks of the car.

D is the coupling-link, and J the couplingpin.

The operation of coupling may be "understood by reference to Figs. 1 and 4, which we may suppose to represent the couplers of two cars approaching each other. \Vhen there is nolink or pin in the coupler, the free end of tongue F drops forward by gravity, so as to (No model.)

hurs have been made containing the triptongue E; also, that the lifting shaft H is not a new device; also, that link-lilting devices have been used in which a lifting armor tongueinside the drawhar head is operated by a shaft coupled to its projecting end outside the head; also, that lilting tongues or arms have been used which are pivoted to both checks of the draw-head, and which are operated by swinging or by vertical arms outside the drawhcad. I do not therefore claim any of these devices; but

What I do claim, and wish to secure by Letters Patent, is-

1, In a canconpler, the linh-guiding device consisting of the arm G inside the mouth of the draw-bar, and the horizontal arnrB ontside the same, both secured together to form a single lever pivoted on one side or check of the draw-bar, and so arranged that lifting vertically the free end of the arm B causes the free end of the coupling-link to rise, allsubstantiall y as described.

2. In the link-guiding device of a carcoupler, the combination of the arm G inside the bar, the horizontal arm 13 outside the same, the trip-tongue E, and the lifting-shaft H, having an arm near its center, all as set forth.

ALBERT K. MANSFIELD.
