CAR-G'OUPLING.

SPECIFICATION forming part of Letters 'Patent No. 484,900, dated October 25, 1892.

Application filed October 27, 1891. Serial No. 409,993- (No model.)

To all whom it may concern:

Be it known that we, HENRY OAKES, residing at Silver City,in the county of Grant and Territory of New Mexico, and BEN OAKES, residing at Chicago, in the county Cook and State of Illinois, citizens of the United States, have invented a new .and useful Car-Coupling, of which the following vis-a specification.

This invention relates to car-couplings, and more especially to the classes thereof known as twin-jaw and rotary-head, and the object of the same is to effect certain ilnprovements in devices of this character.

To this end the invention consists in a carcoupling embodying a construction substantially as hereinafter more fully described and claimed, and as illustrated on the two sheets of drawings, wherein- Figure 1 is a perspective view of the end of a car with our improved coupling attached, showing the jaw in its normal position and viewing the whole slightly from the under side. Fig. 2 is a plan view of the draw-bar, draw-head, and jaw. Fig. 3 is a front elevation of the draw-head with the jaw removed. Fig. 4 is a bottom plan view of Fig. 2, showing the dog in dotted lines as engaging the jaw to hold the latter in uncoupled position, and omitting the ear. Fig. 5 is a bottom plan view of two draw-heads in the act of coupling. Fig. 6 is a central horizontal section through two draw-heads coupled.

Referringto the said drawings, 1 is the car body, beneath which is the block 2. 3 is the draw-bar passing through this block and having an open mouth 4 with a rounded front end 5 and a vertical pinopening 6. 7 is a vertical bolt passing through this draw-bar in rear of its mouth 4, and 8 is a plate on top of the draw-bar under the nut of this bolt, said plate moving in a slot 9 in the block 2, whereby the draw-bar has a slight vertical movement in addition to the longitudinal motion which is permitted by its buffer-springs, (not shown,) as well understood. The opening of the block 2 is extended laterally at its upper end to receive lateral projections of the plate, which projections extend beyond the sides of the draw-bar.

The draw-head has on its exterior an annular groove 10, around which turns the ring- 4 rshaped body 11 of the jaw. Such jaw is double-that is to say, arms 12 project forward and outward from diametrically opposite sides of the ring, and carry at their front ends the jaws proper 13, which are oppositelybeveled on their front faces, as shown at 14. When the jaws of two couplings of this character come together, the four faces 14 strike and slide over each other and the rings 11 (one or both) turn in the grooves 10, so as to permit the jaws to rotate relatively to a suicient degree to permit their beveled faces to v pass each other, as seen in Fig. 5. The lower jaw 13 of each coupling is weighted, as at 15, so that after the jaws pass each other the weights turn them to their normally-vertical position, and the rear faces 16 of the heads are in contact. Said faces are slightly dished, as at 17, Fig. 2, which prevents the jaws disengaging easily when under tension, and at this time the rounded ends 5'of the drawheads permit the two couplings to have a lslight lateral swinging movement, as will be obvious from an inspection of Fig. 6. This ligure also shows how an ordinary link can be coupled into the mouth 4of the draw-head .when this coupling is connected with one of the conventional pin-anddink type.

For the purpose of uncoupling the cars, We

.provide the following devices: 2O is a bracket depending from the car-body and having a

slot

21, and 22 is a rod passing through this slot, having a handle 23 at its outer end and having a block with notched ends 24 (or a pair of stops) on its under side. The inner end of this rod passes through a slot 25 in an ear 26, which is bolted or riveted to the lower jaw 14, the end of the rod having a T-head or cross-bar 27 for preventing its pulling through said slot., and at the other side of the ear an expansive spring 2S is coiled on the rod between a stop 29 thereon and the back of the ear. Thus when it is desired to uncouple the cars the handle 23 is grasped, the rod 22 is raised so as to disengage the outer end of the block 24 from the slot 21, and the handle is drawn out, whereby the head 27 of the rod will draw on the ear and turn the ring 11 around the draw-head. If it is desired to keep the coupling in uncoupled position, the rod is then lowered, so that the inner end of IOO without necessarily moving the rod, as will be clear.

30 is a plate of inverted-U shape, which is secured to the lower side of the draw-bar 3 by the head of the bolt 7 and stands behind 1o the lower arm 12 of the jaw, and this plate has at one side a tongue 31, which projects forward and serves as a stop to prevent the weight from turning the jaw beyond its proper vertical position.

15 32 is a rod passing through an eye in the bracket and having a handle 33 at its outer end, the inner end of this rod being journaled through the downturned portions of said plate and prevented from displacezo ment by any means, as a split pin 37. On the rod within the plate is keyed or otherwise secured a dog 39, whose tip is adapted to be turned forward and upward into a notch in the lower arm 12. With this construction z5 the rod may be turned so as to cause the tip of thedog to stand in the notch 35 when the jaw. 1s 1n vertical position, thus locking it against an automatic uncoupling, and the friction of the rod in the eye of the bracket 3o 20 will prevent the dog falling; or, after the jaw has been swung to uncouple, the dog may be turned forward behind a lug 35 on the body 11 to hold it in this position, as seen in dotted lines in Fig. 4. These devices are 3 5 preferably auxiliary to those above described for operating the device. Still either set of devices could be used for this purpose.

A car-coupling of this character possesses great strength and durability, is automatic in 4o its action, is positive when locked, and is yet easy to uncouple or to lock in uncoupled position. If the cars do not stand exactly in the same horizontal plane, the couplings will work nearly if not quite as well, and should one draw-bar become detached from its support it cannot fall to the ground, and thus perhaps derail a car, because the upper jaw would strike on the front end of the drawhead before the two jaws above said head be- 5o came disconnected. When two cars come together and the jaws are deflected from a veri-- ---ftical line, the faces of the draw-heads strike 6o the spirit of our invention.

each other and act as buEers, thereby taking all the strain off the jaws at this time and allowing the weights 15 to cause the jaws to turn to a vertical position and interlock.

We do not confine ourselves to the exact details of constructiomas considerable change may be made therein without departing from Neither do we limit ourselves to the use in a single device of all the elements and features above described, as some of them might be used alone or in other connections to great advantage.
