LEE KENWORTHY, OF ADEL, IOWA.
IMPROVEMENT IN CAR-COUPLINGS.
Specification forming part of Letters Patent No. 13 1,1 18, dated Dccember 24, 1872.
v To all whom it may concern:
Be it known that I, LEE KENWORTHY, of Adel, Dallas county, Iowa, have invented certain Improvements in Oar-Coupliu gs, of which the following is a specification:
My invention is an automatic car-coupling. It consists of an upright rigid pin, shown in my drawing A, Figure 1, occupying the place usually occupied by the ordinary pin in use in common draw-heads. This pin has a beveled triangular front corresponding to the bevel in the front and lower part of the draw-head. The pin extends up two-thirds of the distance in the cavity of the draw-head. It can either be a pin with a triangular brace in front or a solid triangular piece of iron, as represented by Fig. 4, and fastened in the draw-head by means of an angular dovetailed slot in the bottom of the cavity of the draw-head, the
narrowest part of the slot in front,in combination with a notched iron bar shown by Fig. 3 of my drawing, which works vertically in vertical slot-s or'inortises through the drawhead. This bar is for the purpose of holding the link firmly in the draw-head by throwing the ring D back against the block F. The notch a in the bar falls under the front block G and the link is held in nearly a horizontal position to enter the approaching draw-head in the act of coupling, and prevents the escape of the link when in motion. The bar is also for the purpose of uncoupling by raising the bar with the ring D, until the notch b rests on the top of the draw-head, when the bottom of the square notch E raises the link above the pin A, and the link stands uncoupled. When coupled, the link plays in the square notch E, in front against the pin A, and back against the .back wall of the cavity in the draw-head, the vertical slot allowing the bar to work clear of the link when coupled. The bar has also the projecting-piece ,0, Fig. 1, by which the entering-link raises the bar and falls behind the pin A and into the notch E, and the link is coupled.
Claim.
In the construction of an automatic carcoupling, the triangular pin A and the vertical bar B with the ring D, and the blocks F and G, in combination with an ordinary drawhead and link, substantially as described and for the purposes specified.
Witnesses: L. KENWORTHY.
