OAR-COUPLING.

Specification of Letters Patent.

Patented Nov. 10, 1908.

Application filed. April 1, 1907. Serial No. 365,676.

To all whom it may concern:

Be it known that I, SAMUEL Mounts, a citizen of the United States, residing at Newark, in the county of Licking and State of Ohio, have invented a certain new and useful Improvement in Car-Couplings, of which the following is a specification.

The invention relates to car couplings of the general type commonly known as the J anney and it is the object of the invention to simplify and cheapen the construction and render it easier and more certain in operation.

It is proposed that the coupling shall be automatic in action except that it may be manually operated to set it for uncoupling or to relock the coupling after it has been set for uncoupling.

In the accompanying drawings in which one embodiment of the invention is shown Figure l is a top plan view; Fig. 2 is a horizontal section exposing the interior construction in plan view with the knucklelocking devices in knuckle-locking position; Fig. 3 is a similar section showing the knucklelocking devices set to permit uncoupling; Fig. 4 is a vertical section showing the knuckle-locking devices in the position in which they appearin Fig. 2; Fig. 5 is a similar section showing the knucklelocking devices in the position in which they appear in Fig. 3; Fig. 6 is a similar section showing how the lock-support or rest can be operated to relock the knuckle after said rest has been set for uncoupling or as appears in Figs. 3 and 5.

In the several views 1 designates the head of the draw-bar, which is provided with a cavity suitable to receive the parts.

2 is the knuckle pivoted to swing horizontally at 2 and having a tail-piece 2 extending generally substantially parallel to the jaw portion of the knuckle. The rear vertical wall of the tail-piece is shown to be non-concentric with the axis of the pin 2 upon which it swings, the end portion of said wall being more remote from said axis than that at the root portion of the tailpiece. The knuckle-lock is designated 3 and is rockable vertically on a shaft 4 standing at right angles to the longitudinal axis of the draw-bar so that the lock shall swing in a plane substantially parallel to the axis of said bar. The knuckle-lock carries, preferably on a pivot 5, a rest 5. The rest 5 is formed at its lower end below the pivot 5 with a laterally extending foot 5 and at its upper end above the pivot 5 with an arm 5, and said rest swings in a recess 3" in the side of the knuckle-lock, the wall 3 constituting a stop to limit the forward movement of the lower end of said rest when the knucklelock is raised. WVhen the knuckle is closed, that is, when it is in the position where the cars are coupled, the lock can be raised to un locking position and supported there by the engagement of the rest with the tail-piece 2 as best seen in Figs. 3 and 5. The lock can be thus raised by means of a rod 6, which can be itself or by obvious addition thereto extended to the top of the car, or said lock can be raised by turning the shaft 4, which is shown to protrude through the side of the draw-head and may extend to the side of the car, thus in either case avoiding the necessity of the train-man going between the cars to set the lock.

The upper arm of the rest 5, when the lock is sufficiently raised, abuts against a projection 1 on the rear wall of the cavity above the knuckle-lock, so that the lower end of the rest is thrown rearward, but the tendency of the rest is to rebound (by reason of the weight at the upper end of the rest and in rear of the pivot thereof) from this rearward movement into position to engage the upper side of the tail-piece when the lock is lowered. But if, after the lock is raised, and the upper arm of the rest impinged against the projection 1*, and then promptly lowered before the lower end has had time to swing into position to engage the tailpiece, the lock may be lowered behind the end of the tail-piece into locking position.

Aflixed to the shaft 4 is an arm or kicker 7, which, when the lock is raised to or beyond the position to set it, strikes the tail-piece of the knuckle and impels that member toward open position.

The tail-piece, when the knuckle is in open or uncoupled position, normally supports the lock in elevated position, or so that said piece can swing under the lock, and when the tail-piece is turned outwardtoward open position, it, by reason of the non-concentric rear vertical wall, slides from under the lower end or foot of the rest 5, whereupon the rest drops behind said inner wall, as shown in Fig. 6, where it remains until the tail-piece is turned inward to the coupled or locked position. It being borne'in mind that when the knuckle is in completelyun the tail-piece, it can not, when the tail-piece is turned inward, remount to a position on top the tail-piece. This is due to the fact that the rest is held down by the weight of the lock, and said rest being on a pivot is pushed slightly inward on its pivot by the non-concentric vertical wall of the tail-piece until the latter is inward sufliciently far to permit the lock to drop between the vertical end of the tail-piece and the opposing wall of the coupler head. WVhen the lock thus drops the rest is carried farther inward by the wall 3 of the recess 35in which the rest is pivoted, as shown in Fig. 4. The coupling and uncoupling operations are therefore automatic.

It will be noted that because the lock swings in a plane parallel to the axis of the draw-bar the pressure of the end of the tail piece when there is a pull on the knuckle is on the side of the lock and in a direction per-,

pendi'cular to the axis of the pivot of the knuckle, said pressure being transmitted, when the parts fit close enough, to the side of the draw-head. There is, therefore, no strain, binding, or wear on the pivot of the lock to interfere with its free operation. It will also be noted that if, after the lock has been set and before the cars have been separated, it be deemed unnecessary or undesir-able to separate the cars, the lockcan be replaced to locking position.

What I claim and desire-to secure by Letvbar and alongside of the end of the tailpiece to lock the knuckle in coupled position, said knuckle-lock provided with a rest pivoted thereto adapted to engage the tailpiece to support the lock in position'above the tail-piece, said rest also having an upward extension adapted to engage a wall of the draw-head to throw the rest rearward from said tail-piece.

2. In a car coupling, the combination with a draw-bar and draw-head, of a knuckle having a tail-piece, a knuckle-lock pivoted to the draw-head to swing in a plane substantially parallel to the axis of the draw-bar and alongside the end of the tail-piece to lock the knuckle in coupled position, said knucklelock provided with a recess and a rest pivoted in said recess, said rest being provided with a laterally projecting foot adapted to rest upon the tail-piece to hold the lock in position above the plane of the upper side of the tail-piece, and said rest provided with an upward extension adapted to engage a wall of the draw-head to throw said laterally projecting foot rearward from the tail-piece. SAMUEL MORRIS.
