Specification of Letters Patent.

Patented Oct. "7, 1913.

Application filed. June 20,1912. Serial No. 704,719.

To all whom it may concern Be it known that I, VVILLIAM H. SIMONS, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Car-Couplers, of which the following is a specification.

The chief object of this invention is to provide an improved car coupling of the J ann'ey type in which there is a vertically sliding locking block with means for setting the lock and opening the knuckle, both being operable by means of a sliding pin.

The invention is embodied in the example shown in the accompanying drawings formpart hereof and particularly set forth in the following description, thefeatures of novelty being pointed out in the appended claim. 7

In the said drawings-Figure 1 is a horizontal section on the linejww Fig. 2. Fig. 2 is a vertical section on the line z 3 Fig. 1. Fig. 3 is a perspective view ofthe lock. Fig. 4 is an elevation ofthe lock operating pin. Fig. 5 is an elevation of the inner end of the knuckle. Fig. 6 is an elevation looking at the left hand side of the device as it appears in Fig. 2. Fig. 7 illustrates a modified form of the lock operating pin.

provided with a suitable cavity to receive the operative parts.

8 designates the knuckle which is mounted to swing horizontally on a vertical pin 19, as usual, in such couplings. The tail 8 of the knuckle has its upper and lower sides inclined upwardly toward the side at which the knuckle is pivoted and so that upward pressure against said lower side shall tend to throw the knuckle to openposition.

The lock comprises a body or head por tion 9 of oblong parallelepiped form, generally speaking, having a leg 9 extending downward from its lower side at one end. Said leg 9 is beveled at 9 to permit the tail of the knuckle to pass it when the lat-' ter is oscillated. The cavity of the draw head is constructed with a vertical recess in which said lock can move vertically and be guided but permit the lock to slightly rock in a plane transverse the draw head.

10 is a wall in the lower portion of the cavity, the upper end of said wall affording a shoulder upon which the leg 9 rests to support the lock in its elevated position, as shown by broken lines Fig. 2.

The lock operating pin 11, which is best illustrated in Fig. l, consists of a body provided with a longitudinal opening 11 through which the lock projects. The pin at the lower end of this opening engages the lock to raise the same when the pin is raised. The pin wo-rksvertically in groove extensions 12 and 12 of the recess for the lock and is guided in its vertical movements thereby. The pin is arranged to engage the look when raised at one side of the center of gravity of the look so that the latter when supported by the pin tilts sufficiently to throw the lower end of the leg over the shoulder of the wall 10. Hence in the preparation for uncoupling when the pin is released the leg engages and rests on the shoulder, as indicated by broken line Fig. 2.

Pivoted at 13 at the lower side of the draw head is an angular lever 14, the free extremity of which extends to a point in the cavity of the draw head under the tail piece of the knuckle. This lever 14 extends through a slot 11 of the pin 11. The lever 14 is operated by the pin 11 to throw the knuckle to open position, the pressure of the extremity of the lever on the inclined under side of the tail acting thereon to effect this result, but the slot or opening 11 is made suiiiciently long to permit the lock to be raised to position to be supported on the wall 10 before raising the lever 14 to thus actuate the knuckle. If the lever 14 be raised to actuate the knuckle the lock is further raised but when the pin is released, the lock drops upon the tail of the knuckle and is supported thereby but tilted in the opposite direction. When the lock is supported on the wall 10 the knuckle is free to turn outward to open position but when turned to full proper open position the high part of the tail of the knuckle engages the under side of the head of the lock and lifts it slightly so that it tilts in the opposite direction and fetches the lower end of the leg out of line with the shoulder of the wall 10 thereby permitting the lock to drop into knuckle locking position when the tail is turned inward to the position it occupies when the knuckle is closed, as seen in Figs. 1 and 2. The operation therefore is briefly this: When it is desired to uncouple coupled cars equipped with such a coupling the look is raised by raising the pin until the lock is supported by the shoulder of the wall 10. The pin is then released and the cars can be separated. In separating the cars the knuckle is pulled to open position and in this operation the tail unseats vthe lock and supports it until the coupling is again coupled with another. Should it happen that the knuckle has not been in the uncoupling operation drawn to full open position, that position can be obtained by raising the pin 11 until the lever 14 actuates the knuckle and moves it to the proper position.

The pin 11 is shown as extending at its upper end through a hole in the top of the draw head, and provided with an eye for the attachment of an actuating device, but said hole in the draw head can be closed and the pin can be shortened and formed at its upper end as shown in Fig. 7. The pin in either form can be raised by means of a bent lever 15 fulcrumed in ears 15 at the under side of the draw head and provided with an eye 15 to which is connected a rod (not shown) extending to the side of the car, as usual, so as to be accessible without the necessity of going bet-ween the cars.

To prevent the dropping out of the knuckle pin 19 should it become broken I provide a headed pin 15 held in position under thelower end of said pin 19. Said pin 16 is passed through holes in an ear 1'? on the draw head and in the ears 15 and is secured from accidental removal by means of a cotter pin 18 inserted through the inner end of said pin 16 where it extends beyond Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

tending downward from its lower side at one end and an independent slidinglifter pin 11 in said draw head adapted to engage the other end of said block- 9, said leg 9 adapted when the block is'sufiiciently raised by partially raising the lifter pin ito swing laterally into engagement with said shouldered wall 10 to set the sameand be released from said shoulder wall by swinging in the opposite direction whentheblock is engaged by the inclined upper side ofrthe tail of the knuckle when the latter isswung to open position, and a bent lever l iinde V pendent ofthe lock to act onthe lower in clined side of the tail piece, said lever being actuatedby said sliding pin to move the knuckle toward open position when said lifter pin is raised beyond the point to set the lock. p f
