GAR COUPLING.

LEWIS E. HUNT, OF HIRAM, GEORGIA.
CAR COUPLING.
SPECIFICATION forming part of Letters Patent No. 390,602, dated October 2,1888.
Application filed February 27, 1888. Serial No. 265,510. (No model.)
To aZZ whom it; may concern.-
Be it known that I, LEwIs E. HUNT, a citizen of the United States, residing at Hiram, in the county of Paulding and State of Georgia, have invented a new and useful Car-Coupling; and I do hereby declare the following to be a full, clear, and exact description of the inven tion, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
This invention has more particular reference to the class of car-couplings in which the pin is raised from or lowered into its place without the necessity of going between the cars; and it consists of mechanism for accomplishing this in a satisfactory manner and in the least complicated way, all of which will be hereinafter fully described, and the parts claimed as new pointed out in the claims.
In the accompanying drawings,Figure l is a side elevation, partly in section, showing the pin in its place when coupled and other operative parts. Fig. 2 is a front view of the draw-head, showing the pin-lifter and contigtr ous parts. Fig. 3 is a horizontal section of the draw-head,'showing the shape of the recess for the pin.
In the figures, like reference-marks indicating corresponding parts in the several views, A is the draw-head; B, the pin; Z), the linkguide, and b the spring attached at one end to the draw-head and at the other to the pin in any suitable manner.
I do not confine myself to the form of spring shown, as it might be either a flat spring attached to the pin in the same way substantially as the spring shown in Fig. 2, or one having a bifurcated end partially encircling the pin.
O is the eccentric arm for raising and forcing downwardly the pin, said arm 0 being pivoted to the standard D, and having the levers d in the desired number attached thereto.
The draw-head A may be of any form suitable for the purpose. The sloping under face of the guide b is for the purpose of guiding the entering link under the end of the pin, and also prevents the pin being accidentally withdrawn from the draw-head. This guide will also cause the entering link to assist the arm in raising the pin on the entrance of the link in the opposing draw-head into the draw-head having no link. To keep the pin fromjarring out, the springb is attached in such a manner as to cause it to press the pin into the seat a in the bottom of the draw'head. In the upper end of the pin is a hole, through which passes the eccentric arm 0, which eccentric, when partially revolved around the pivot d in the standard I) in the direction of the arrow, Fig. 2, will, by its eccentricity, raise the pin to any height necessary to allow of the free entrance of the link. The spring I) may be dispensed with, if desired, and the eccentricity of the arm 0 continued to such an extent as to clamp the pin.
It will be seen in the drawings that for approximately one-fourth of its length at the lower end the guide I) is sloped at a much more acute angle to a horizontal line than for the residue of its length. This is for the purpose of reducing the force required to cause the link to lift the pin by reason of its contact I with this incline.
The bottom part, a, of the opening of the draw-head is flared or inclined for a considerable length, as shown, in order that the link may be deflected byit and raised so as to prevent its passing under the stationary drawhead as it approaches thereto.
The operation of this device is as follows: To couple cars, the link passing into the drawhead is lifted in transit by the incline at the point a. A further entrance will force the pin up, owing to the inclination of the guide b, which inclination will also cause the link to enter under the end of the pin as soon as said pin shall be raised sufficiently to allow such entrance between the end of the pin and the bottom of the opening in the draw-head, on which entrance the spring I) and the force of gravity will cause the pin to return to its position, and the operation of coupling is complete. To uncouple the cars, the pin is raised by partially revolving the eccentric arm in the direction of the arrow, Fig. 2. The link may then' be freely withdrawn,and the operation of uncoupling thereby completed.
This device may be attached to the drawhead of the ordinary pinand-link coupling without changing the form of the draw-head otherwise than attaching the spring and standard in any desired manner and cutting a recess for the guide 1).
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-
1. In acar-coupling, the combination of the eccentric arm 0, the standard D, and pin B, for the purpose specified.
2. In a car-coupling, the combination of the eccentric arm 0, the standard D, the pin B, and the guide I), substantiallyas shown and described, and for the purpose specified.
3. In a car-coupling, the combination of the eccentric arm 0, standard D, guide 1), spring b, and a lever or levers for operating the arm 0, substantially as shown and described, and for the purpose specified.
In testimony whereof I affix my signature, in presence of two witnesses, this 2ith day of 20 February, 1888.
LEWIS E. HUNT.
