T on whom it may conoern: This spring elastically draws the part C of Be it known that I, JOHN BAMART, a citizen the locking-lever toward the piece E for a purof the United States, and a resident of the city pose hereinaftermentioned.

The lower portion of 70 of the parts of the coupler when the latter is the rod has a guide K fixed to the rod and out of use. Fig. 3 is a vertical longitudinal working between or within fixed guiding-surcentral section of the car-coupler and showing faces. The guide K therefore reciprocates the position of the parts of the coupler when with the lockingpiece H, and the latter is so the latter is in use and coupled to another car. held as to always drop directly upon the lock- 75 I will now proceed to particularly describe ing-lever O as the latter is raised, and not my invention. only so, but it directly engages with and in A indicates the coupler head or box, conthe recess C of the locking-lever C.

The locking-piece H therefore continually presses toward the lockingpiece 0.

When the guideways of the guide K area cylinder, the guide K will preferably lie altogether within the latter, as shown.

The rod H is moved away from the coupler-head by hand or any suitable necessary device, and a suitable device is to be arranged for holding it when drawn out when such holding for any reason becomes necessary;

The mode in which my invention operates is as follows: The parts are ready for coupling when in the position shown in Fig. 2.

.There the locking-piece H is held up and out of the way by the surface of the lockinglever in contact therewith. As the couplinglink L is forced or pushedin its forwardend impinges against the surface C below the locking-piece H, and, overcoming the oppo- In such event the rod H and its accompanying mechanism would join the locking-piece at the side instead of the top.

My invention is economical of manufacture and simple of operation and effective in use.

What I claim as new and of my invention, and desire to secure by Letters Patent, is

1. In a car-coupler, the combination of the reciprocating locking-piece H with rounded end, and an opposing pivoted lever C, having a concave depression 0 to receive the piece H, and a curved convex surface 0 at the rear thereof, the lever 0 being provided with means for enabling the arm of lever C -which carries the convex surface 0 to continually press toward the locking-piece H, the locking-piece H havingmeans for causing it to elastically advance toward .leverO, when permitted so to do, substantially as and for the purposes specified.

2. In a car-coupler, the combination of the pivoted lever 0 having forward concavity 0 H, allows the latter .to move forward into the opening between the ends and sides of the link, as shown in Fig. 3. lV-hen the lockinglever Chas been brought into the position last named, its concavity O is directly beneath the locking-piece H, and the latter-passing through the link enters the recess 0 This thelocking-piece H willdo, inasmuch as it is propelled by the spring K. The parts are .now 'securely locked.

In some instances it may be desirable to draw the locking-piece H out of contactwi-th,

The partsof the coupler are now in readiness to be coupled with aand rear rounded surface 0", and a spring strained between the point .0 of the lever, and the detent E, and the locking-piece H, elastically advanced by a spring, and provided with a rod, and reciprocating in guideways, substantially as and for the purposes specified.

3. Ina car-coupler, thecombination of the pivoted lever 0 having forwardconcavity G and rear rounded surface 0 and .a spring strain-ed between the point C of the lever, and the detent E, and the locking-piece H, and rod H and fixed guide gK, and moving guide K and spring K between the same, substantially as .and for the purposes specified.

4. In-a car-coupler, the combination of the pivoted lever 0 having iforward concavity C and rear rounded surf-ace O and a spring strained between the point C of the lever, and the detent vE, and the locking-piece H, and rod H thereof for movingthe same, and the cylinder K connected to the couplinghead,.and themovable guide K on the rod H and the-stationary guide K covering the top .of the cylinder, and forming a,cap thereof,
