SPECIFICATION forming part of Letters Patent No. 303,583, dated August 12, 1884.
Application filed January 23, 1884. (No model.) Patented in Canada April 17, 1853, No. 16,699, and September 12, 1883, No. 17,665.
To all whom it may concern.-
Be it known that we, GEORGE MITCHELL, of Newcastle, in the county of Northumberland, in the Province of N ew Brunswick, and WILLIAM DAVID ll/IARTIN, of Moncton, in the county of Westmoreland, in the aforesaid Province, Canada, have invented a new and useful Automatic Car-Coupler, of which the following is a specification.
Ourinvention consists, mainly, first, in hinging the draw-head to the draw-bar, so thatthe head may move vertically within a limited angle to suit the different height of a car to which it might be connected; second, in replacing the ordinary coupling-pin by a latch-hook depressed by a spring, and placing a shaft across the draw-head, with levers for raising said latch when uncoupling the cars.
In the drawings, Figure 1 is a longitudinal vertical section of ourimproved coupler. Fig. 2 is a side elevation. Fig. 3 is a top View, and Fig. 4 is a cross-section of the same.
A the draw-bar, and B the draw-head, are connected by a hinge-joint consisting of the tongue a, fitted inaslot-mortise formed in the end of the head, and pivoted by the pin 1).
The upper portion of the tongue at is lengthened out to fit in a corresponding recessin the head for preventing the head from being raised above a straight line with the draw-bar, and the shoulders c of the head being slightly sloped inward and downward to allow of the downward deflection of the head. The headB, being thus movable vertically within a limited angle, adjusts itself to the height of the adjacent head and link to which it is desired to be coupled.
G is the latch-hook. It is pivoted at the forward end of the head in two lugs, (1, cast on or otherwise secured to the upper surface of the head. The nose 0 of the latch-hook projects into thelink-ehamber f of the draw-head, sloping rearward and downward, so as to present a nearly perpendicular shoulder to the end of the coupling-link D, between the shanks of which it is made to be a loose fit. The latch-hook is held down in the chamber f by a spring, E, one end of which is secured to the upper side of the draw-head, and the other end bears upon the swinging end ofthelatehhook to hold it down.
F is a standard formed on the top of the draw-head, and upon which is fulcrumed the lifting-lever G, the inner end of which is connected with the swinging end of thelatch-hook by a chain or link, g, of any approved pattern.
H is a roek-shaft placed transversely to and journaled in bearings formed on the under side of the draw-head. On the ends of this rockshaft are formed or rigidly secured the hand lever h, by which the coupling may be operated. The roek-shaft H is also provided with an arm, 2, the swinging end of which is connected with the outer end of the 1ifting-lever G by the rigid rod j. From this it follows that the latelrhook may be raised by simply depressing the hand-levers h.
That we claim as our invention is- 1'. In a car-coupler, the lifting-lever G, fulcrumed in the standard F, and connected by the link 9 to the latch-hook O and by the rod j to the arm 73 of the rock-shaft H, substantially as described.
2. In a car-coupler, the draw-bar A, pivotally connected to the draw-head B by means of a hinge-joint, substantially as shown, and for the purpose hereinbefore set forth.
3. The combination, in agar-coupler, of the draw'bar A, hinged to the draw-head B, the latch-hook G, pivoted to the draw-head B and projeetingitsnose einto the chamber f, formed therein, and the spring E, bearing 011 the latchhook,with thestandard F, lifting-lever G, and link 9, with the rock-shaft H, having the handlevers h h, and the arm 92, connected with the lifting-1ever G by the rod j, substantially as shown, and for the purpose hereinbefore set forth.
Signed at Newcastle this 22d day of Decent ,ber, 1883.
GEORGE MITCHELL. WILLIAM DAVID MARTIN. In presence of JOSEPH A. RUssELL, Guns. J. THoMsoN.
