SAMUEL SELDEN, OF ASPEN, COLORADO.
CAR-COUPLING.
SPECIFICATION forming {part of Letters Patent No. 528,346, dated October 30, 1894.
Application filed February 28, 1894- Serial No. 501,811. (No model.)
To aZZ whom it may concern.
Be it known that I, SAMUEL SELDEN, a citizen of the United States, residing at Aspen, in the county of Pitkin and State of 0010- rado, have invented certain new and useful Improvements in Automatic Link-and-Pin Oar-Couplers; and I do 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 appertains to make and use the same, reference being had to the accompanying drawings, and the letters of reference marked thereon, which form apart of this specification.
The object of my invention is to provide an automatic car coupler, that is extremely simple and efiective in operation.
From the drawings it will be seen, that the drawhead is of the usual design, excepting in the items of pin, pin hole and link chamber.
Figure 1 is an illustration of the drawhead, showing how the pin bears or presses on the link and it shows the position of the link ready to enter the link chamber of the op posing drawhead. Fig. 2 is a longitudinal section of the drawhead showing the pin in the raised or elevated position. Fig. 3 is a longitudinal section through two opposing drawheads in locked engagement. Fig. 4 is a top view of the drawhead showing the pin hole. Figs. 5, 6, 7 and 8 show the pin in detail. Fig. 7 is a transverse section of thepin along line 02-41: of Fig. 5, and Fig. Sis a transverse section of the pin along line 41-31 of Fig. 5.
A is the drawhead.
B is the pin.
O is the link.
The drawhead A is of the usual design. Its link chamber a differs from ordinary practice only in the fact, that it has a lip or flange a. at the bottom side of the entrance. This lip or flange 0. acts as a prop or fulcrum for the link, when the end of the link in the link chamber is pressed down by the weight of the pin, thus forcing the projecting end of the link up to proper alignment for entering the opposing drawhead. The bottom-0t of the linkchamber a is constructed so that there is a fall, inclination or drainage toward the pin hole, in order to prevent the collection and freezing of Water in the link chamber. The pin hole through the top of'thelinkchamber conforms to the section of the pin B along line a;x Fig. 5, but the rear wall of this pin hole has an offset a near its top, in order to permit the pin to lean back to the position shown in Fig. 2.
The pin B has a projection or rib 5, along a portion of the body of the pin. This projection or rib b has two essential functions,
one to press the end of the link in the link chamber down, and the other, to prevent the .pin when hung in position for coupling, as
shown in Fig. 2, from catching, when the pin is disturbed by the concussion, caused by two cars coming together; this concussion being the means of dropping the pin B from its supports into the pin hole and through the link.
The pin B is provided with two shoulders I) as shown in the drawings. These shoulders b',-b', hold the pin B up in position for coupling. The pin is raised by the usual operating lever either from the top or side of the car, and inso raising the pin, its head is naturally slightly pulled backward. Therefore, as soon as the shoulders b'b' emerge from the'pin hole, they will engage on the top plate of the clrawhead and thus hang the pin,
as shown in Fig. 2. The shoulders b-b' are placed somewhat above the lower portion of the projection or rib b, so that when the pin is hung for coupling, this projection or rib b, that is the lower portion of same, still remains in the pin hole.
From the foregoing description, the method of effecting the coupling will be readily understood. The link and pin in onedrawhead being placed as shown in Fig. 1, and the pin of the opposing drawhead being raised for coupling, as shown in Fig. 2, the concussion caused by the two drawheads coming together will drop the pin into the pin hole and through the link, and thus the automatic coupling is accomplished.
What I claim is- The combination, with the drawhead having a flange or lip at the bottom side of the entrance of the link chamber, of the coupling In testimony whereof Iaflix my signature in pin having a projection or rib at its rear side presence of two Witnesses.
throughout a portion of its len th and two 1 shoulders, one on each side of th e phrojection SAMUEL SELDILN 5 or rib; these shoulders being placed somelVitnesses:
