SPECIFICATION forming part of Letters Patent No.

Application filed January 2S, 1882. (Model.)

To all whom it may concern:

Be it known that I, NEWELL P; COWELL, of Gleveland,in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Car-Couplers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art towhich it pertains to make and usethe same.

My invention relates to car-couplers, and more particularlyto that class known as automatic car-couplers,77 that are adapted to engage with the opposite couplers when the same are brought together without the interposition of any mechanical device or endangering the life or limbs of a brakeman; and it consists in parts and combination of parts, aswill more fully hereinafter be described and claimed.

In the accompanying drawings,Figure1 represents an isometric view ot' the under portions of two opposite car-platforms carrying my improved couplers, one of the couplers being shown in closed and the pther in open adjustment. Fig. 2 is a view showing the couplers locked together. Fig. 3 is a horizontal sectional view through one draw-bar and coupler,

showing the mechanism for locking the coupler in open and closed adjustment; andFigA is a` similar view, showingthe stop drawn out and disengaged from the pivoted couplinghead. y

In the drawings, AA 4represent `the plat forms, preferably of passenger-coaches.

B B' represent t-he draw-bars, which consist preferably of two metal plates sufficiently removed to permit theintroduction ot the spring and stop5also, the pivoted head or coupler C, which is also adapted to turn upon the pivot I). The pivoted head shown in Fig. 3 is provided with the angular portion c, which is adapted to engage with the same angular portion of the opposing coupler. Itis also provided with another angular face upon its opposite side, as shown at c2, which is adapted to bear against the stop E when the coupler is open, as shown in Fig. 1. The pivoted head has shoulders or' projectionson its side, which slide upon the circular `portion of the plates composing the draw-bars. Thus the pivoted head is adapted to revolve backward until the shoulders strike the non-circular portion of the draw-bar.

or becoming disengaged from the hook D', a spring and suitable locking mechanism may be provided.

What I claim is- 1. The combination, with a draw-bar, of a coupling-head pivoted to the endthereof and provided with an angular face, c, and with the straightfaces dand c2, and the spring-actuated stopv interposed between the draw-bar and coupling-head, and adapted to operate substantially as described.

2. The combination, with the draw-head B and coupling-head C, pivoted in the head of l the draw-head, of the sliding stop E, located in a recess formed between the coupler and 15 draw-head, said stop being constructed with a .orwardlyprojecting arm at its lower end and a rearwardly-projecting arm at its, upper end, and al spring located between a seat on the draw-head and the rearwardly-projecting arm zo of the sliding stop, substantially as set forth.

In testimony whereof Ihave signed myname to this specification in the'presence of two subscribing witnesses.'
