P. 0. SEYMOUR. Oar-Coupling.
N0. 218,069. Patented July 29, I879.
UNITED STATES PATENT OFFICE.
FRANK O. SEYMOUR, OF ST. LOUIS, MICHIGAN.
lM PROVEMENT IN CAR-COUPLINGS.
Specification forming part of Letters Patent No. 218,069, dated July 29, 1879 application filed April 1, 1879.
To all whom it may concern.-
Be it known that l, FRANK O. SEYMOUR, of St. Louis, in the county of Gratiot and State of Michigan, have invented an Improvement in Oar-Couplings, of which the following is a specification.
The nature of this invention relates to new and useful improvements in the construction of car-couplings; and the invention consists in the peculiar construction of parts, their combination and operation, as more fully hereinafter set forth.
Figure 1 is a perspective, partially in section, showing the draw-bar in place. Fig. 2 is a horizontal section on the line :20 :10.
In the accompanying drawings, which form a part of this specification, A represents the end or head of a draw-bar, provided with the mouth B, flaring in all directions. This month terminates at the rear in an opening or throat rectangular in form, longest in vertical crosssection, through which the coupling-bar O enters the head. This coupling-bar, being harpoon shaped at both ends, enters said opening or throat, when the shoulder of the harpoou'head on the under side engages with the rear side of the lug D, at the same time forcing the gate E upward until the upper shoulder of the harpoon passes the downwardlyprojecting flange F of the gate, which then falls, thereby securing both shoulders of the harpoon within the head. This gate is constructed substantially in the form shown, and to its bottom end is secured the stop plate a, which, by its impingement against the bottom of the draw-bar, prevents its withdrawal from above; and it is also provided with a stop, (I, which strikes against the upper part of the head within the recess, and prevents the gate from being withdrawn should the stop plate a be removed. This gate works in halt-dovetail ways in the interior of the draw-barhead. which holds the same rigidly in position and confines its motion to a vertical reciprocating one.
G is a plate or metallic block, or projection from the bottom, designed to perform two functions, to wit: It operates as a weight to keep the gate E depressed, so that it is always ready to engage with a coupling bar, and to release the coupling-bar from its engagement with the stud D as the gate and plate are raised, the plate impinging against the under side of the couplingbar to compel such rcleasement.
A lever, H, pivoted to the draw-bar and connected to the head of the gate may be employed, so that the uncoupling may be done from either side of the car.
What I claim as my invention is The combination, with the draw-head A B, of the vertical slide E, Working in half-dovetail ways in the head, and provided with pin b, plate a, and block G, and the lever H, pivoted to the top of draw-head and to said slide, constructed and arranged substantially as described and shown.
FRANK C. SEYMOUR.
