CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 294,565, dated March 4, 1884.

' Application filed November 12, 1883. (No model.)

To all whom it may concern;

Be 'it known that I, WILLIAM A BENJAMIN, of Cleveland, in the .countyv of Cuyahoga, in the State of Ohio,have invented an Improved Car- Coupling; and I do hereby declare that the fol lowing is a full, clear, and exact descriptionthereof, reference being had to the annexed drawings, making a part of this specification, in which like letters of reference refer to like parts, and in which- Figure l represents a vertical longitudinal section of the car-coupling; Fig. 2, a perspective view.

The object of this invention is the construction of a car-coupling in which the pin can be raised out of the link by mechanism operated at the outside of the car, thereby obviating the necessity of the operator going between the ends of the cars, in which the pin, when thus raised, is retained and dropped automatically, and in which the link of one draw-head can be vertically shifted to suit theA height of the approaching draw-head by means of mechanism operated at the outer side of the car.

My invention consists of a rotative arm run-. ning from side 'to side at the end of the car, and having at its center an arm by which the pin ,of the draw-head can be raised, and of a plate pivotally secured at the bottom of the opening in the draw-head, and having means Vfor raising and lowering it.

In the drawings, A is the draw-head, constructed similar to those ordinarily used, and having, as in others, a slight elastically-controlled longitudinal play between the crossbeam G and stirrup G',

B is the link, and Cthe pin, which are shown in Fig. l in place,the former being also exhibited as being vertically adjusted to fit the height of the draw-head to be coupled with. rI-he plate D, by which this adjustment is accomplished, is pivoted at its rear end by the horizontal bolt or pin D', running through it and the `sides of the draw-head. The front edge of this plate D, when resting upon the lower side ofthe draw-heads opening, is protected from collision with 4an incoming link by means ofthe guard a. Vertically through this plate D is of course a, sufficient opening to make way for the pin C. Below the plate across-bar equal in length to the width of l the plate D. The said plate being raised by the upward pressure of said pin E,the wear between the twois decreased by having thelatter thus T-shaped, and it is also retained thereby in place. To raise said T-pin E, I usually employ avlever pivoted nearits center and running froin said pin tothe outer side of the ear. By the depression ofthe outer end of said lever, the inner end, and therefore the pin E, are raised. In Fig. 1, Ishow, however, a shaft, F', having suitable bearings and running from side to side beneath the car. From' this shaft F' extends an arm, F, which, as said shaft is partially revolved', raises the pin E,or permits it to drop by its own Weight and that of the plate D. The upper surface of the plate I), I make somewhat concave, as shown in Fig. 2, so that the link B may be held thereby in `the center ofthe draw-head. l

To enable the link-pin G to be withdrawn from the outer side of the car, I have designed the rod H', having at its center the arm H, between the two parts of which extends a neck, C', from the upper end of the pin C. -A crosspin, C2, at the head of said neck C', retainsthe same in the arm H. Asshown'in Fig. 2, the arm H is made from the same rod H', the center portion of which is'bent to form said arm.

Said arm H may be a broad bar slotted through its center and made fastto the rod H'; but the former way I deem preferable. Suitable bearings, H3 H3, are provided for said rod H', and

handles or cranks H2, constructed at its ends, to enablethe turning of the same. To prevent loss of the links by the dropping to the ground of the extra one, in the case where two contiguously-coming draw-heads have each a link, I have designed the hooks L-one at each side ofthe cars end*upon which the extra linkY may be hung until wanted again.

In using my car-coupling, the pin C of one draw-head israised by turning the rod H'until the notch at thelower end of thepin rests on the edge of its opening A', and holds said pin in position, asv shown in Fig. 2. The plate D is of course resting upon the lower side of IOO the opening of the draw-head A, and having its front edge behindthe guarding-ridge a. In the draw-head to be coupled with this one the link B is resting upon the plate D,and thelinltpin C down through the same. If the two draw-heads are not of the same height, the plate D is raised or lowered by means of its operating mechanism, previously described, until the outer end of the link B is at the proper height to suit the oncomingdraw-head. As th c draw-heads cometogethenthey are each pressed backward by the yielding ofthe springs usually constructed therewith, until the opening A, coming directly beneath the upper end 0i' the link-pin C, the vpin has its notch released therefrom, and therefore drops through the link B, which had entered in beneath.

Vhat I cla-im as my inventioinand for which I desire Letters Patient, is as follows, to wit:

l. In a coupling` for cars, the drawliead A, in combination with the plate I), T-pin E, and means, substantially as shown, whereby said pin is elevated, for the purpose set forth.

2. The draw-head A, in combination with l the concave plate l), having pivot D, T-pin 25 l for the purpose specified.

3. rIhe draw-head A, having boss E2 and opening IG, in combination with the T-pin E, concave plate l), having pivot D and central opening, and the shaft F,having arln F,wherc by said pin E and plate l) are moved vertically, for the purpose set forth.

4. The draw-head A., opening E, and boss E?, T-pin ll, plate D, having pivot D', arm F, and shaft IW, in combination with thc link B, pin C, having neck C', and cross-pin C2, rod ll and arm II, suitable bearings and handles, Il, as set forth.

In testimony that I claim the foregoing invention I have hereunto set my hand this 7th day ofovcniber, A.. D. 1883.

XVILLIABI A. BENJAMIN.
