OLIVER S. DALE AND ABRAM BARNES, OF MICHIGAN CITY, INDIANA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 276,005, dated April 17, 1883. Application filed February 28, 1883. (No model.)

To all whom it may concern:

Be it known that we, OLIVER S. DALE and ABRAM BARNES, citizens of the United States,

residing at Michigan City, in the county of La Porte and State of Indiana, have invented certain new and useful Improvements in Car- Oouplings; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanyin g drawings, and to the letters and figures of reference marked thereon, which form apart of this specification.

Our invention relates to a car-coupling of the class operated by link and pin; and the novelty consists in the construction and arran gement of parts, as will be more fully here'- inafter set forth, and specifically pointed out in the claims.

The object of the invention is to provide a self-coup1ing attachment for railroadcars, one which shall operate automatically to couple the cars as they come in contact, and one which shall allow the uncoupling to be performed with the operator upon either side or upon the top of the car; and to these ends the invention consists, essentially, in the mechanisms fully illustrated in the accompanying draw-' ings, which form a part of this specification, and in which Figure 1 is a perspective view. Fig. 2 is a sectional View, and Figs. 3, 4, and 5 are detail views.

Referring to the drawings, in which similar letters of reference indicate like parts in all the figures, A represents a car, and B a drawhead secured thereon. The construction of the car and the particular manner and means of securing the draw-head form no part of this invention. .The draw-head may be made in sections or in a single casting, and has the ordinary flaring mouth, I), which receives the coupling-link M.

Within the draw-head is formed a recess, 0, which connects with and forms part of the link-chamber Z), adapted to receive a couplingdog, D, which is loosely pivoted in the drawhead at (Z in such manner that when in position it will turn upon its pivot in a direction away from the mouth of the draw-head to admit the link; but when turned in the opposite direction the free end will abut squarely on the bottom of the link-chamber. This dog has a tongue, (1, formed upon its free end, which tongue is adapted to be received within the link 0, and ears perforated at (1 which receive apivotal pin, and thereby connects said dog D with a vertical bar, F, the functions of which will be explained.

Secured at e to the draw-head B is a spring, E, having spring-jaws e, which have bearings upon the dog D upon each side of the tongue d, the space between the jaws 6 being made to accommodate said tongue. It will thus be seen that as the cars come together the link will enter the mouth I) of the draw head, strike the dog D to overcome the force of the spring E, turn the dog D on its pivotuntil the end of the link enters the link-chamber, when the tongue (1 will drop into the link-cavity, and the link be thus held locked in position, but having the necessary play to allow for the swaying of the cars.

To a stud, q, secured to the bumper or other convenient part of the car, is pivoted a link, G, to the free end of which in turn is pivoted the vertical bar F, at a point some distance below its upper end. This bar has pivoted at its upper end a hand-rod, H, which extends through proper guides h, and is provided at its upper extremity with a ring or other catch, it, adapted to engage a corresponding catch, h secured upon the end of the car to lock the rod H at its highest elevation against the constant force of the spring E.

Pivoted to the car at t, upon either side of the center, is a lever, I, the inner end of each of which rests under the link G, while the opposite end extends outward, and when at rest is supported in a bracket, i, but may be locked against the force of spring E by being passed under said bracket. It will thus be observed that the force of the spring E may be overcome by either the rod H or either of the levers I by the attendant, and the cars uncoupled and the locking-dog held out of enga gement with the coupling-link when desired.

Modifications in details of construction may be made without departing from the principle or sacrificing the advantages of our invention, the essential features of which will be readily understood, both in construction and operation, from the foregoing description. taken in connection with the drawings.

Having thus fully described the invention, what we claim as new is-- 1. [he draw-head B, having recesses b 0, dog D d, and fiat spring E e, in combination with the link G, bar F, rod H, and the pivoted levers or handles I, and means for holding their outer ends depressed, substantially as set forth 2. In combination with the draw-head B, having recess 0 and I), the dog D, formed "as OLIVER S. DALE.
