' UNITED STnTE s PATENT OFFICE;
THOMAS P. 'BEADLE, OFOLIMAX, MICHIGAN.
SPECIFICATION forming part of Letters Patent No. 531,497, dated December as, 1894. Application filed February 2'7, 1894- Serial No. 501,642. (No model.)
To all whom it may concern:
Be it known that I, THOMAS P..BEADLE, a
citizen'ofthe United States, residing in .the
township of Climax, in the county of Kalamazoo and State of Michigan, have invented certain new and usefulImprovem'ents in Car- Oouplers, of which the following is a specifi- My invention relates to improvements in automatic hook car couplers.
The objects of my invention are, first, to provide an automatic hook car coupler that shall be pivotally connected to the draw bar and to the car; second, to provide an automatic hook car coupler that shall readily couple when the cars are on the curved track; third, to provide in an automatic hook car coupler against any tendency to become uncoupled when the train is passing around a curve; fourth, to provide means to keep automatic car couplers free from ice; fifth, to
provide in an automatic car coupler means of securely retaining its bolts so that there will be no danger of the trains becoming uncoupled from this cause;. sixth, to provide an automatic hook car coupler in which the force of gravity assists in coupling and retaining the coupler in position; seventh, to provide in an automatic hook car coupler, means'of decreasing the lateral strain on the draw-bar; eighth, to provide an automatic hook car coupler that is'perfectly safe; ninth, to provide an automatic hook car coupler that 'prevents all slack motion between the cars and gives, at the same time, facility in moving the train around a curve. 7
I accomplish the objects of my invention by the devices shown in the accompanying drawings, in which 4o Figure l'is a top plan view of my improved coupler joinedtogether, one end being shown in section on linel-l of Fig. 4. Fig. 2 is a top plan view of one end of the same, the dotted lines showing the method of swinging from side to side. Fig. 3 is a view in section on line 3-3 of Fig. 2. Fig. 4 is a side elevation of Fig. 1, showing the appearance of the coupler just after it is uncoupled. Fig. 5 is a sectional view on line 55 of Fig. 2.
Similar letters of reference refer to similar parts throughout the several views.
In the drawings, I show no means of operating the car coupler as my invention does not relate to the means for operating it, but only to themain hooking parts.
In the'drawings, A represents the draw-bar; B, the pivoted draw-head which is rounded into a true circle next to the car and is pivoted on a heavy pin, D, at the center of the curve. .In a curved slot, E, to the rear of the pivoted draw-head is a pin, E,which serves to prevent the draw-head, B, swinging too far to one side. To the front part of the pivoted draw-head, pivoted on the horizontal bolts, F, are hooks, O, which are made symmetrical to each other so that each hook can drop over a catch consisting of bolt, F, on the opposite portion of the coupler and, in this way, I secure a double hook to the coupler which gives itgreater security. The hooks, O, are so pivoted that they swing up, and the under frontside of them is curved so that the parts readily pass over the catch composed of the bolt, F, and a raised portion of the pivoted ets, F, to protect them from wear and preserve them so that they will not become worn and broken, and also add to their strength. It will be noted that the hooks, 0, act by gravity to drop into the notches made for the bolts, F, in the draw-heads.
In the front of the pivoted draw-head, B, recesses, r, are formed to receive the links of the ordinary link coupler so that my improved coupler can be readily utilized with the old fashioned'link couplerby'inserting the link in the recess and dropping the link pin through the holes, n, n. w
Just below the points of the hooks, 0, when I my improved coupler is joined together, I make an opening, 25, of considerable size to allow all water or snow that may lodge on the coupler to fall through, when the hook drops down, which will keep the seat for the hooks, 0, free from snow and ice and allow them to them to hook readily both at once.
operate freely. Ihe fronts of the recesses or grooves for receiving the hooks, O, on my improved coupler, are shaped something like funnels so that, when the cars strike together, the hooks will strike in the recesses and swing the couplers to the proper position to allow Springs, a, are shown above each hook to depress it and insure a more perfect action of the coupler, when the cars are brought together, and secure the hooks from bounding out of place; but where the hooks, C, are made heavy, the springs, a, can be dispensed with as the weight will be suificient to insure the proper action of the same.
I desire to say that my improved coupler is capable of considerable variation in its details and still embody my invention.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In an automatic hook car coupler, the combination of draw-heads, B, pivoted to the draw-bars by bolts, D; bolt, E, in the slot,E, to limit the lateral motion of said draw-heads; hooks, O, in longitudinal grooves pivoted to bolts, F, to engage a catch in the opposite facing corresponding member; and spring, a,
to force the hook, 0, down, all substantially as described for the purpose specified.
2. In an automatic hook car coupler, the combination of the draw-heads, B, pivoted to the draw-bars by bolts, D; bolt, E, in the slot, E, to limit the lateral motion of said drawheads; books, 0, in longitudinal grooves pivoted on bolts, F, to engage catches in the oppositely facing corresponding members, all substantially as described for the purpose specified.
3. In an automatic hook car coupler, the combination of draw-heads,B, pivoted to the draw-bars by bolts, D; bolt, E, in the slot, E, to limit the lateral motion of said drawheads; pointed hooks, O, in longitudinal grooves pivoted on bolts, F, to engage catches in the oppositely facing members; and funnel shaped guideways to receive said hooks and guide the coupler together, for the purpose specified.
In witness whereof I have hereunto set my hand and seal in the presence of two witnesses.
