SPECIFICATION forming part of Letters Patent No. 393,268, dated November 20, 1888.
Application filed February 2'7, 1888. Serial No. 265,416. (No model.)
To all whom, it may concern.-
Be it known that I, WILLIAM ROBINSON, of Bellefontaine, in thefeounty of Logan and State of Ohio, have invented certain new and useful Improvements in Automatic Oar-Couplings; and I 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 pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.
My invention relates to an improvement in automatic ear-couplings; and it consists in the combination of a buffer-head, which is recessed on its inner side, with a spring-actuated hook, which is pivoted in the recessed bufferhead, and which has a cam or projection formed upon its inner side for the projection on the operating-lever to strike against and thus force the hooks apart to uncouple them, as will be more fully described hereinafter.
The object of my invention is to produce a car-coupling which can be used in connection with the usual link and pin, if so desired, but which is automatic in its action, simple in construction, and always reliable.
Figure 1 is a plan View of a ear-coupling embodying my invention. Fig. 2 is a detached viewof the operating eross-rod. Fig. 3 is a perspective of a coupling embodying my invention. I
A represents the buffer-head, which is recessed on its inner side to receive the pivoted hook B. Through the front end of the bufferhead and in the front end of the hook B is formed a suitable opening or recess, 0, so that the ordinary link can be used in connection with a coupling of this kind. The couplingpins, when links are used, are passed down through the opening D, which extends through the front end of the buffer-head only. Each head is recessed, as here shown, so as to have the coupling-hook placed entirely within it, and thus protect the front ends of the hooks when the ears run together, so as to prevent them from being crushed or broken. Bearing against one of the timbers of the cars atone end and against the rear end of the hook at the other is a suitable spring, F, which keeps the front end of the hook always pressed 5o the points of the hooks to pass each other.
Upon the outer edge of the hook is formed a cam or beveled projection, G, against which the beveled projection II upon the operating cross-rod I strikes, for the purpose of forcing the hook back into the recess in the head and thus uncoupling it. The red I is jour naled upon the under side of the car and is provided with a handle, J, at each end. The projection II hangs downward below the buf fer-heads until one of thchandlcs is operated,
when this beveled projection H is forced down ward, so as to strike against the cam or projection G upon the hook and force the front end of the hook backward into the recess in the head.
In order to prevent the buffer-heads from being moved laterally far enough to allow the hooks to become uncoupled, a guard, O, is secured to each car, as shown, and which is just sufficiently far removed from the buffer-head to allow the end of the opposing buffer-head to freely enter. The hooks being held in position by means of the springs F, and the heads A being prevented from moving laterally by the guards, it is impossible for the 8c cars to become disconnected after they have once been coupled, unless the red I is operated.
In case it is desired to operate the red I from the top of a freight-car, a rod will be made to extend up the side of the ear in the usual manner, and which will be connected to one of the handles J. In case this coupling is to be applied to a passenger-car, a short lever will be pivoted upon the end of the car and connected to the front end of the hook by a short connecting-rod, which passes through the outer side of the buffer-head.
This coupling being automatic, there is no necessity of the brakeman venturing between 5 cars, is cheap and simple in construction, is
positive in its operation, and dispenses with I the beveled projection H, and the guard which IO all necessity for brakenien to couple the cars is secured to the end of the earl, substantially together. as described.
Having thus described my invention, I Intestinnony whereof I affix my slgnntureln clnimpresence of two witnesses.
The combination of a buffer-head recessed WILLIAM ROBINSON. upon its inner side, with the spring-actuated pivoted hook placed in the recess and provided with a cam, G, the red I, provided with \Vitnesses:
