CAR-COUPLING.
SPECIFICATION forming part of Letters Patent No. 352,264, dated November 9, 1886.
Application filed August 11, 1886. Serial No. 210,650.
To all whom it may concern.-
Be it known that 1, MARK M. REQUA, of Lanesborough, in the county of Fillmore and State of Minnesota, have invented a new and 5 Improved Automatic Oar-Coupling, of which the following is a full, clear, and exact description.
My invention relates to the construction of a cheap, durable, and efficient coupling for any I form of car, but applicable more especially for use in the coupling of freight-cars, one of the main objects of the invention being to provide a coupling which may be used in connection with the ordinary form of pin-and-link I coupling as well as with couplings constructed in accordance with the terms of my invention. Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the views.
Figure 1 is a longitudinal sectional view of two draw-heads provided with my improved form of coupling, the construction on the right representing the couplingpin as raised to position to be upheld by the connecting-rod of the tumblers, while upon the left the parts are represented as they appear when the pin is passed through the opening in the link and the tumblers are resting upon the inner end of the link, holding it in position to couple automatically with the coupling of an approaching car. Fig. 2 is an inverted plan view of the coupling, taken on the line a: at of Fig. 1. Fig. 3 is a face view of the coupling, the right- 3 5 hand portion thereof being shown in section.
In the drawings, 10 represents vthe drawhead that is formed with the ordinary opening or recess, 11, the lower defining-wall of this recess being inclined, as best shown at 5 upon the left in Fig. 1. 1n the upper portion of the draw head there are formed two recesses, as 13, and within these recesses there arepivotally mounted tumblers 15, the forward faces of which are formed with recesses 2. The tumblers 15 are connected bya crossrod, 16, which is so located that when the tumblers are in the position shown upon the right in Fig. 1 the rod 16 will be beneath the coupling-pin aperture 17, the coupling-pin 18 being preferably formed with a slot, 3, in its lower end, through which there is passed a (No model.)
cotter, 4, which prevents thepin from being entirely withdrawn from the draw-head.
The tumblers 15 serve to hold the extended end of the coupling-link 20 elevated, as shown 5 5 upon the left in Fig. 1, the tumblers being of sufiicient weight to overbalance and raise the extending end of the link, and as the lower defining-wall of the recess 11 is inclined the end of the coupling-link will be raised to a position to couple automatically with the adjacent car.
Vhen it is desired to uncouple the cars, the pin 18 is raised, in order that the link may be withdrawn, and as the link is withdrawn the tumblers will fall to the position shown upon the right in Fig. 1, the rod 16 at this time passing to a position beneath the point of the pin 18, and it will be clearly understood that when the parts are in the position just described the tumblers will be thrown back by an entering link, so as to permit the pin 18 to drop into the opening of said link.
Having thus described my invention,what I claim as new, and desire to secure by Letters 5 Patent, is
1. In a car-coupling, the combination, with a draw-head, of tumblers pivotally mounted therein and connected by a rod, substantially as described.
2. In a car-coupling, the combination, with a draw-head formed with recesses 13, of turnblers formed with recesses 2 and pivotally mounted within the recesses 18, and a connecting-rod, 16, carried by the tumblers, substantially as described.
3. The combination, with .a draw-head and its coupling pin and link, of tumblers pivotally mounted within the draw-head, and a rod carried by and connecting the tumblers, substantially as described. A
4. In a car-coupling, the combination, with a draw-head formed with recesses 13 and an inclined lower defining-wall, 5, of acoupling link and pin and tumblers pivotally mounted 5 within the recesses 13, said tumblers being formed with recesses 2 and connected by a rod, 16, substantially as described.
