CAR-COUPLING.

SPECIFICATION forming part of Letters Patent N 0. 472,857, dated April 12, 1892.

Application filed July 25,1891- Serial No. 400,695. (No model.)

To aZZ whom, it may concern.-

Be it known that I, JOSEPH B. CARPENTER, a citizen of the United States, residing at Marietta, in the county of Greenville and State South Carolina, have invented certain new and useful Improvements in Oar-Couplings; and I do hereby declare the following to be a full, clear, and exact description of the invena signal secured to the end of a car and adapted to be operated by the coupling or uncoupling of the cars; and with these objects in view my invention consists of the parts and combinations of parts, as will be hereinafter more fully described and claimed.

In the drawings, Figure 1 is a front elevation. Fig. 2 is a bottom plan. Fig. 3 is a sectional view on the line X X, Fig. 1. Fig. 4is a longitudinal central section. Fig. 5 is a detail view.

Similarletters refer to similar partsthroughout the several views.

A represents a car of usual construction; B and B, the two jaws, which have flared ends. These jaws are slotted at b b, in which slot works bolts.

C C are sides of a casing or housing around the jaws B and B. The draw-head, composed of the jaws B and B ,acts also as a draw-bar.

Secured to the housing-O are springs D D,

which bear against the jaws B and B on each side. These springs D D keep thejaws tightly together and allow them, as a body,

to move from side to side in working around a curve. If the jaw B should be forced to one side by a curve in the road, the jaw B would be forced up against the jaw B by the force of the spring D. This state of facts would exist in case the jaw B was forced to one side.

E is a buffer-spring located back of and bearing against the jaws B and B. The jaws B and B each have a groove 1) b.

F is a rod having a crank F. Secured to the rod F is an oblong-shaped projection said projection being rounded on its ends and working in the grooves b b in the jaws B and B. F is a disk secured to the rod F underneath the car, and is provided with a drum F to which is attached one end of a chain or rope Y. body is a lever F having a cam-head F to which is secured the other end of the chain Y. G are springs secured in the recesses G in the jaws B and B. These springs serve to lift the coupling pin or link out of the recess G when it is desired to uncouple the cars.

H is the coupling-link having the heads h. This pin is swelled in the center, and has slots it cut entirely through it from the sides.

I is an alarm secured to the car in a suitable place, and I is a striker secured to the jaw B.

The operation is as follows: One end of the pin I-I being secured toa car,thefree end is pushed against the jaws of the next car, which open under the pressure, and the pin forces the jaws apart and the head of said pin falls into the recesses G. To uncouple the cars, I pull the lever F out avery slight distance and this, through the chain Y, revolves the disk F which in turn revolves the rod F and the oblong projection f in the groove 1), which gradually opens the jaws, and the springs G raise the pin H to a position where it can be pulled out of engagement. (See Fig. 5.) In case it is desirable or necessary to uncouple the cars from the top, thebrakem an operates the handle F, which works independent of the lever F.

I make one head of the link H smaller than the other, so that in case any of the cars in a train should leave the track it will pull the link at such an angle that the derailed car will uncouple itself by pulling the small hea of the link out of the draw-head.

It is to be understood that the cars will not uncouple on a curve, no matterhow short it is, but will only uncouple when the car leaves the track. It is obvious that the link H can be bent, in order to adapt it to couple cars of different heights, and that the slots h form Pivoted near the edge of the carhandles, whereby the same can be readily and .the springs-D and E, of a rodhaving the handled. projectionf, working in said grooves 19, the
