`'WILLIAM L. ALBRIGHI, OF CHATTANOOGA, TENN CAR-COUPLING.

SPECIFICATION forming pari; of Letters Patent No. 356,972. `dated February 1,- 1887.

Application led October 18, 1886. Serial No.2l6,519. (No model.)

To aZZ whom it may concern:

Be it known that I, WILLIAM L. ALBRIGHT, a citizen of the United States, residingat Chattanooga, in the county of Hamilton and State of Tennessee, have invented certain newr 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 make and use the same.

My invention consists of an improvement in car-couplings of that class in which the coupling-pin rests upon a latch hinged to the inner side of the draw-head, and in Whichon the entrance of the link, the latch is thrown up and permits the pin to fall through a hole in the latch and thus automatically `couple the cars. Y

My improvement is illustrated in the accompanying drawings, in which Figures 1 and 2` 1are central sectional elevations.

In the drawings, A is the draw-head, provided With a flaring mouth, B, to admit ofthe free entrance of the link at any angle, and from this mouth -the draw-head extendsback, forming-a chamber, B', in which the latch is hung, and provided with a recess, c, cut out from the uppervportion of the chamber B', to receive the latch. The Width of this chamber is made greater than its height, to permit of a free lateral movement of the latch Within it, and to prevent all cramping and bending of i the link.

D is a latch, having its entire upper surface straight and its entire under surface curved, as shown, and hinged by means of a countersunk bolt, bf, in a grooved recess, bz, formed in the draw-head just back ofthe curved upper portion of the mouth and on a line with the upper door of -the chamber B. The bolt and head of the latch are thus protected from all chance of abrasionand injury. The latch is thus curved so that its upper end may conform to the curved recess b2, and that its point only may rest on the floor of the draw-head; also to present the least frictional resistance tothe link and to increase its weight by giving to its center additional thickness.

F is a coupling-pin With ablnntend, adapted to rest With that end partly Within a hole in the center of the latch, and which is provided with a hole, o, at its top to suspend thersame, by means of a chain, to the draw-head or top of the car.

G is afuunel formed in the top of the draw-n head, and constitutes a support and sure guid- A car-coupling composed, in combination,

of a draW-head provided with the flaring month, the grooved recess b2 behind the upper curved portion of said mouth, the couplingchamber of a Width greater than its height, and provided with a latch-recess, c, the latch having its top surface straight and its entire under surface curved and pivoted to the drawhead by a conutersunk bolt in recess b2, the

funnelin the top of the draw-head to control and guide the pin, the latch, and the bottom of the draw-head provided with holes in a line with they funnel to receive the coupling-pin, substantially as described.

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

WILLIAM L. ALBRIGHT.
