CYRUS F. BAKE, OF FULLERTON, NEBRASKA.

CAR-COUPLING.

SPECIFICATION forming part ofv Letters Patent No. 574,233, dated December 29, 1896.

' Application led October 22, 1896. Serial No. 609,643. (No model.)

Be it known that I, CYRUS F. BAKE, a citi- Zen of the United States of America, residing at Fullerton, in the county of Nance and State of Nebraska, have invented certain new and useful Improvements in Car-Couplings; 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 to which it appertains to 1n ake and use the same, reference being had to the accompanying drawings, and to letters of reference markedv thereon, which form a part of this specification.

This invention relates to car-couplings of the style known as the MasterCar-Builders type, sometimes designated as twinjaw and it consists in certain details of construction, hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure l is a hori- Zontal sectional View of a car-coupling constructed in accordance with my invention. Fig. 2 is a vertical longitudinal sectional view. Fig. 3 is a front elevation, the knuckle being removed. Fig. 4 is a detail perspective view of the knuckle. Y Fig. 5 is a detail perspective view of the pivoted vertical latch.

A designates the draw-head, which is connected to the car body or frame in the usual manner and is provided at its forward end with a projection to which the knuckle B is pivoted. The upper edge b of the operatingarm B of the knuckle B is inclined downward, so that the end will strike lower down on the vertical latch C, hereinafter described, and enable it to more easily raise said latch. This inclination also allows the end of the operating-arm to pass under the latch and only raise it a short distance up and back out of its vertical position. The upper and lower edges of the operating-arm are notched, as shown at b and b2, and one of the upper corners is beveled or rounded, as shown at b3, to present a curved surface that will impinge against the latch in passing under the same. The inner part of the draw-head is so constructed that when the knuckle is swung to a closed and locked position the end of the arm thereof will lie within a recess, and one side of the mouth of said draw-head is provided with an opening or recess d, through which the reduced end of the arm passes.

It will be here noted that the arm of the knuckle, when the latter isclosed, bears against the draw-head for only a short distance of its length and that the bottom of the chamber in said draw-head is curved or inclined downward toward the mouth to prevent accumulation of dirt or other matter that would affect the proper operation of the coupling.

C designates the vertical latch, which is pivoted in the upper part of the draw-head upon a transverse pin C, and with this latch the end of the arm B engageswhen the knuckle is swung upon its pivot in coupling the cars. This latch is provided in its edge which adjoins the recess or seat for the arm Bl with a recess c, in which is journaled a roller C', said roller projecting slightly beyond the latch that it may engage the operating-arm. and the edge of the latch in front of this roller is beveled, as shown at c2.

By providing the roller C' and beveled or rounded edges c2 and c4 it will insure the prompt falling of the latch, and being present less exertion will be required to lift the latch when the coupling is made and the arm is in engagement therewith. The latch is also provided with a shoulder c3 in front of its pivot, and this shoulder contacts with the upper part of the draw-head to prevent said latch from swinging too far forward by limiting such movement.

To the latch (l is connected a rod d, that eX- tends through an opening in the draw-head, as shown, and may be connected to any suitable means for lifting or operating the latch..

shown in my prior patent, dated Febuary 18, 1896, and numbered 554,970.

In operation as the knuckle is closed in coupling the cars the rounded or beveled corner b3 of the operating-arm B will strike against the outer face of the latch C and lift said latch to permit the arm to pass beyond the same, and when said latch falls to its vertical position the smooth face of the operating-arm will engage the roller C', and thus permit the latch to be easily raised in uncoupling the cars. When the operating-arm B is swung, the end of said arm which is reduced IOO The rod may be operated by the mechanisml by thc cut-away portions forming the notches b and b2 Will lie Within the recessed side of the draw-head, the end of said arm being positioned rear of the latch. The second notch b2 has its vertical Wall ou a line with the vertical wall adjoining the inclined portion l), so that the bearing-surfaces of the coupling-arm in the draw-head will be equal at the top and bottom.

lt will be noted that when the cars are coupled the latch eilectually covers the opening or mouth of the draw-head and that a very long operating-arm is permissible by providing the recess ain the mouth of the draw-head.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The combination in a car-coupling, of the draw-head having a chamber With a forwardly-inclined bottom and a. mouth with a recess or opening a in one side; a knuckle presenting an operating-arm having the upper edge l) inclined downward; together With a pivoted vertical latch C, anda roller C journaled in said latch to be engaged by the operating-arm of the knuckle, substantially as shown and for the purpose set forth.

The combination, in a car-coupling, of the dra\\f-head having a chamber with a recess in one side and a mouth with an opening a opposite said recess; a knuckle presenting an operating-arm IIB having an upper inclined edge, and a rounded corner; together with a pivoted vertical latch C'havn g a beveled forward edge c? and a recess e' adjoining the same, and a roller C journaled in said recess to engage the operating-arm, the parts being organized substantially as shown and for the purpose set forth.

The combination with the draw-head having a knuckle pivoted thereto, of the vertical latch C pivoted in the draw-head and provided with a shoulder cs at its upper end, a rounded corner c2, and a recess c in one edge; and aroller C journaled in said recess to bear against the operating-arm of the knuckle when the latch is being raised, substantially as shown and for the purpose set forth.

1. The combination with the draw-head having a knuckle pivoted thereto, of the Vertical latch C pivoted in the draw-head and provided with a shoulder c3, a rounded edge c4, a rounded corner c2, and a recess c; together with a roller C journaled in said recess to bear against the operatingarm of the knuckle when the latch is being raised, substantially as shown and for the purpose set forth.

In testimony whereof I ailix my signature in presence of two witnesses.

CYRUS F. BAKE.
