To all whom it may conccrle: dislodgmcnt of the pin P is prevented by Be it known that I, HENRY DEITZ, acitizen projection A and slot P, as described. of the United States, residing at Chicago, In coupling, the end B of the knuckle B 55 county of Cook, State of Illinois, have inrotates against the lower end of the pin P 5 vented a new and useful Improvement in Carand swings it backward, thereby permitting Couplers, of which the following is a specithe knuckle to revolve in place, whereupon fication. the pin P drops back to its normal vertical My invention relates to that class of coupposition between the end B" of the knuckle 6o lers generally known as the Master Carand the wall A of the casting A, the pin re- Builders standard of verticalhook coupvolving on the point A of the casting A as a lers; and the objects of my invention are to center, as shown in Fig. 2, the lip P engagproduce a coupler composed of a minimum ing said projection A The location of this number of parts, that are strong, durable, center is such that the center of gravity of and easily manufactured, and yet having the the pin at all times is such as to cause the I 5 merits that will be particularly described pin to fall in the desired vertical position.

Fig. 2 is a vertical longitudinal in a triangular opening P which opening P sectional view on line 2 2 of Fig. 1. Figs. 3 (see Figs. 7 and 8) is located at one side of and 4: are views similar to Fig. 2, showing the pin, producing, as it were, a side draft in the locking-pin in a different position. Fig. lifting the pin, which aids in swinging the 5 is a side view of the locking-pin in a reverse lower end outward and slightly over the end 25 position from that shown in the foregoing Bof the knuckle when the pin is at its highfigures. Fig. 6 is a sectional plan view on est position. The pin is aided in being lifted line 6 6 of Fig. 3. Fig. 7 is a front vertical in this inclined position bymeans of the lower sectional view on line 7 7 of Fig. 1. Fig. 8 end of the slot P being beveled out, as is So is a front vertical view of the locking-pin. shown in Fig. 7, whereby when coming in 0 In the drawings, A designates the main contact with the projection A the lower end body casting of the coupler, and B the of the pin is forced outward, causing it to pass knuckle-piece. These two castings are made over the end B of the knuckle, and upon the in the ordinary method to conform to the release of the tension of the chain upon the Master Car-Builders lines,but being provided pin P it falls downward and rests upon the 3 5 with a locking device, as I will now describe. end of the knuckle, as is shown in Fig. 3.

P designates the locking-pin, which is pro- The small projection P on the pin P and the vided with a slot Pin one side thereof, which projection B on the knuckle insures a safe slot engages the projection A on the interior lodgment of the pin P upon the knuckle end 0 cavity of the casting A, and in the use of the B, whereby the coupler is held in position to 40 coupler this projection A and slot P prebe uncoupled, as desired, by the trainmen, vents the removal of the pin; but when it is whereupon by the outward movement of the desired to remove the pin from the coupler knuckle in uncoupling the pin P rides off the lower end of the pin is swung backward from the end of the knuckle and falls into in the position of the dotted lines in Fig. 2 its normal position ready to automatically 5 and is then lifted upward a short distance, lock the knuckle on its return home.

thereby clearing projection A from the slot In the event that the knuckle should be P, whereupon on the further lifting of the locked home at the time when a coupling is pin P from the coupler projection A passes desired to be made a device is provided 011 10c downward through a recess P of the pin P, the bottom of casting A to enable the brake- 50 as shown by Fig. 4, and thus the pin P is man to throw open the knuckle ready for permitted to be withdrawn from the casting coupling without placing his hands in a po A 5 but in the use of the coupler accidental sition likely to'be injured by the accidental keepers Hof the casting A, connected by pin H engaging a slot in a lever 11, pivoted at H to the bottom of casting A and provided with a projection H, which extends upward through a slot in the casting A and engages the back of the knuckle, whereby by pulling on the handle H the projection H is thrown against the knuckle and forces it outward, the pin P having previously been lifted. A projection A on the interior of the casting A, Fig. 2, serves as a stop for the pin P in swingin g backward.

On the end B of the knuckle B there is a projection B which engages a projection A in the casting A, Fig. 1, when the knuckle is locked home, which engagement of said projections prevents the removal of the knuckle in the event of the pivot-pin 13" being removed accidentally when the cars are coupled together, the peculiar position of the locking-pin P holding the projections B and A together even in the absence of the pin B, which may at some time prevent accident to the train.

Vhat I claim is 1. The combination with a draw-head and a knuckle pivoted thereto to swing horizontally in a recess in the same, of a locking-pin arranged to be lifted vertically above the knuckle and also pivotally supported in front of its own line of gravity to be swung temporarily rearward, in a vertical plane, by the knuckle passing to coupled position, and means whereby such lifting automatically swings the lower end of the pin from said plane, to rest upon a suitable support adapted to prevent its descent.

2. The combination with a recessed drawhead and a knuckle pivoted thereto to swing in the recess, of a locking-pin having in front of its line of gravity a pivotal support allowing the pin to be swung rearward by the knuckle and also to be lifted above the plane of the latter, a projection extending from the draw-head into the plane or path of the pin, said pin being provided with a channel, to receive the projection, adapted to allow both swinging and raising of the pin While limiting the latter movement.

3. In a coupler of the class described, the combination with a draw-head and a knuckle pivoted therein upon a vertical axis, of a lockin g-pin pivotally supported upon a horizontal axis, located above the path of the knuckle, and swinging rearward in a plane intersecting said path, and means whereby lifting said pin throws its lower end laterally out of said plane and over the knuckle when the latter is in coupled position, substantially as and for the purpose set forth.

4. In a coupler of the character described the combination of a locking-pin, of means for raising said pin vertically in unlocking, of means for inclining the said pin when raised in a manner that it may engage the end of the knuckle as shown, with projections on the end of said pin and knuckle for insuring the holding of the pin upward by the knuckle.

5. The combination with the recessed and slotted draw-head, of the knuckle pivoted to swing in the recess, the centrally-pivoted lever having upon one arm a projection extending through the slot in the draw-head to force the swinging of the knuckle, and having its other arm slotted, and the bar mounted to slide transversely upon the draw-head and provided with a projection engaging in the slot in the lever to actuate the latter.

In witness whereof I have hereunto subscribed my name, on this 29th day of October, 1895, in the presence of two subscribing witnesses.

HENRY DEITZ.
