JOHN STRONG ANDREWS, OF MILI/POXVN, NEW B EUNSVVICK, CANADA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 366,642, dated July 19, 1887,

Application filed February 7, 1857. Serial No, 226,796.

To (LZZ whom it may concern:

Be it known that I, John STRONG AN- DREWS, of Milltown, in the Province of New I'h'unswick, of the Dominion of Canada, have invented a new and useful Improvement in Railway-Oar Couplers; and I do hereby declare the same to be described in the i'ollowingspeci' fication and represented in the accompanying drawings, of which- Fignrcl is a top view, Fig. a front elcvation, and Fig. 3 a longitudinal and median and horizontal section, of a pair of my improved car-couplers as disengaged and arranged in the positions they have when applied to two cars to be coupled by them. Fig. 4 is a vertical and median longitudinal section of them as disengaged, while Fig. 5 is a horizontal longitudinal section of the said pair of couplers as engaged with each other.

The nature of my present invention or ill)- provemont is defined in the claim hereinafter presented.

A carronpler heretofore invented by me, and for which I have applied for a patent, had to its body three curved horns projecting therefrom, and within the body a recess, and in advance of suchin the median horn-there was a spring-catch.

In carrying out my present invention I have dispensed with one of such horns viz., that which projected upward-and in place of it I have an abutment. Furthermore, I have also virtually dispensed with the median horn, and in lieu thereof I employ a simple projection in which there is arranged crosswise of it the lockingeatch and its actuatingspring, the object of so dispensing with the upwardlycnrved horn being to enable the coupler,without obstruction from the horn, to pass under the platform ofa car, toward which it may be moved, to couple with the coupler underneath such platform.

From one side of the body A of each coupler there is extended a single curved horn, 13, which curves outwardly and downwardly relatively to such body. At the other side of the body and opposite such horn there is a shoulder or abutment, 0, directly between which and the horn B is the projection D, in and through which is a latch, E, and its operative spring F, all being formed and arranged as shown. A hole, a, goes down through the abutment and into the horn, such hole being (No n odel.)

for reception of a pin to engage the coupler with a common link, when such may be desirable. In rear of the latch there is a chamber or recess, 1), in the body A.

\Vhen one coupler is forced toward the other for being engaged with it, the bevel of the latch of one will be pressed against that of the latch of the other, in consequence of which both latches will be moved lengthwise in their carriers until one of such latches may pass the other, in which case their springs will move them in opposite ways, and thereby cause the two couplers to become engaged. By pulling either latch backward sufficiently in its carrier or projection D a disengagement of the two couplers may be effected.

The horns of the couplers serve, when butting together, to guide the latch of one into contact with and to aid in causing it to prop erly act against that of the other. The abut ments, when in contact, arrest at the proper time the advance of one coupler relatively to the other. I would remark that the projection Dis beveled or rounded, as shown, in order that when such projection may be forced against that of another coupler of like kind, in the act of coupling two cars, the rounded parts shall guide the catch of one to that of the other for them to engage with each other.

I do not claim a ear-coupling constructed as represented in the United States Patent N 0. 169,981, for although such is provided with laterally sliding and interlocking jaws arranged to play horizontally in projections, as is the case with my car-coupling, it has not. other devices incident to my carcouplcr-that is to say, it has not to each body part the curved horn nor the abutment, nor their ar rangement relatively to the intermediate projection carrying the spring-latch.

Therefore I claim The car-coupler, substantially as described. consisting of the body A, the single curved horn I the abutment G, the intermediate projection D, the recess or chamber b between such projection and horn, and the springlatch E in such projection, all being arranged essen- [0O tially in manner and to operate as set forth.
