Description
JAMES PEARSON, OF SACRAMENTO, CALIFORNIA.
IMPFOVEMENT IN CAR-COUPLINGS.
Specification forming part of Letters Patent No. 131,826, dated October 1, 1872.
t heads; and Fig. 5 represents the couplingbar or link in elevation `and cross-section. s
The invention relates to the class of automatie ear-couplings; and consists in the oombination of devices, hereinafter described and specifically indicated in the' claim.
Aand B in the drawing represent the respective draw-heads; af a, the coupling-bars hinged to the draw-heads; d s, the stirrups of the same 5 .and b the double-headed couplinglink. The draw-heads have each a vertical eX- ten sion or frame, bf, in which the enlarged heads ofthe coupling-bars a work up or down. Each of said bars has an arm, c, to which a pin, e,
is attached by a chain, h, the office of said pin being to lock the heads of the bar a to the frame b when the coupling is effected.` I contemplate applying a padlock to these parts, when desirable, to prevent tampering with the coupling. The link b has a swell or enlargement on one side, at t', to cause its arrow-shaped heads to assume the proper position to engage with the lower part o of the draw-heads.
It will be seen that when two cars, provided v with my improved coupling, come together the link will enter the draw-heads and raise the heads of the coupling-bars and then drop into the position shown in Fig. 4. Thus, the coupling is automatic in its operation. To release the coupling-link the pin e is first With drawn, and then the hooked bar a is elevated at its front end, which causes the stirrup (l s to raise the end of the link, as in Fig. 2, when it may be readily drawn out.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
The combination of the pin e, frame b of the draw-head, and the coupling-bar a, as and for the purpose specified.
JAMES PEARsoN.
