LOREN M. WEBB -AND EDW'IN TINKER, OF TUSOARORA, NEW YORK.
IMPROVEMENT IN CAR-COUPLINGS.
Specification forming part of Letters Patent N0. 207,921, dated September 10, 1878; application filed July 6,1818.
To all whom it may concern Be it known that we, LOREN M. WEBB and EDWIN TINKER, of Tuscarora, in the county of Steuben and State of New York, have invented a new and Improved Oar-Coupling, of which the following is a specification:
In the accompanying drawings, Figure 1 represents a vertical longitudinal section on line m x, Fig. 2, and Fig. 2 a horizontal section on line y y of Fig. l, ot` our improved carcoupling.
Similar letters of reference indicate corresponding parts.
Thisinvention has reference to that class of car-couplin gs that couple automatically on the approach of the cars by the entrance of the coupling-link into the connecting draw-head, so as to prevent the going in between the cars, and avoid the danger to life and limb connected with the common coupling in use; and the invention consists of a draw-head with open sides, and a central guide-block of less width and length, along which the slotted side plates of a spring-acted pin-supporting front plate are guided. The coupling-pin is guided in a cylindrical pin-guide or barrel at the top of the draw-head, and supported by an extension of the sliding front plate until the same is pushed back by the link. Transverse ribs at the face of the front slide-plate serve to hold the link in position for coupling, while a hand-lever that engages one of the side plates sets the ribbed front plate forward or backward on the center guide-block.
teferring to the drawings, A represents a draw-head of the usual size, made with curved or tapering mouth, but preferably with open sides. rlhe draw-head is provided with a solid center guide-block, B, which is of less width than the draw-head and considerably shorter, so as to leave a sufficient space between the mouth and front end or face of the block for the coupling-link.
Along t-he guide-block B are guided, by headed pins or other devices, the slotted side pla-tes B', `which are connected in front of the guide-block by a front slide-plate, C, that is bent forward topform an angular extension, on
which -tl1e coupling-pin D rests before coupa ling. The front slide-plate, C, is cushioned by a spiral spring, c, that throws the slide-plate forward as soon as the pin is raised for uncoupling.
The pin D is guided in an upright cylindrical barrel or guide, D', secured to the top of the draw-head inline with the pin-holes, and uncoupled by any suitable mechanism from the top, side, or platform of the car. A collar plate around the head of the pin prevents the dropping of the pin through the pin-holes.
The front slide-plate, O, may be slightly com caved for the coupling-link, which strikes against the same on entering and forces the plate back, so that the coupling-pin drops and couples the link. The front plate, O, is arranged with transverse ribs b, that form a groove between them for taking hold. of the link, so as to sustain it inproper position for entering the opposite draw-head. A ribbed rubber front maybe used, if desired.
The slide-plate C may be moved forward by a hand-lever, E, that is fulcrumed into a recess of the center block B, and extended sidewise through a recess of one ofthe side guide-plates. The lever admits the setting of the ribbed front plate so as to obtain the proper position of the link for entering the approaching drawhead. In coupling, the front plate and lever are moved back by the link. Thus a simple and automatically-working car-coupling is ob-l tained that couples with the common pin and link, and which may be applied with. great facility to the common draw-heads in use.
Having thus described our invention, we claim as new and desire to secure by Letters Patent- The draw-head of a car-coupling open at the sides, having guide -block B, and provided with slotted slide-plates B', the latter connected in front by a plate, H, as shown and described, for the purpose specified.
