CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 779,601, dated January 10, 1905.

Application filed June 24, 1903. Serial No. 162,860.

To all whom it may concern.-

Be it known that I, JAuns A. HINSON, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Couplers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in car-couplers; and the invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a top plan view of two connected couplers embodying my invention, one coupler being shown partly in section. Fig. 2 is a side view of one of the couplers with parts broken away to show the interior construction. Fig. 3 is a transverse section of one of the coupler-heads, taken on the indirect line 3 3 of Fig. 1. Fig. 4 is a transverse section taken on the indirect line 4 4 of Fig. 2. Fig. 5 is a detail illustrating a fragment of the coupler-head hereinafter to be explained. Fig. 6 is a top plan View, partly in section, illustrating the manner of connecting my improved coupler with couplers now in use, the type of old coupler herein shown being the Van Dorn coupler.

As shown in the drawings, A A designate the draw-bars of two adjacent couplers, B B the hollow draw-bar or coupler-heads thereof, and C C horiZontally-swinging knuckles pivoted to and between laterally-projecting upper and lower arms I) 6 at the sides of said heads by means of vertical pivot pins Z2. Each of said heads is provided on the side thereof opposite to its swinging knuckle C with a rigid forwardly-extending hook B,

which is directed laterally away from the knuckle of said head and pointing in the same direction as the hook end of the knuckle. Said hook B of each head is connected with the coupler-head by means of a stem or shank B Preferably the said hook B and its shank B are made hollow.

B B designate laterally-directed guardarms, one on each coupler-head just in rear of its hook B, and between each guard-arm B and the adjacent hook B is provided a space which receives the hooked end of the knuckle of an associated coupler, the hook of one coupler having interfitting connection with the knuckle of an associated or connected coupler. Said guard-arms are strengthened by suitable webs or braces B. When the couplers of' my improved type are brought together in coupling relation, the shanks of the hooks of the two couplers lie together side by side with their hooks directed laterally and oppositely, as clearly shown in Fig. 1, and the knuckles of two adjacent couplers pass over the lateral hooks from the outside thereof in the act of coupling. Thearrangement herein shown constitutes, therefore, a double coupler wherein the knuckles of two adjacent couplers instead of intercoupling, as in the ordinary type of couplers now in use, interfit with the rigid hooks B of the connected couplers. The parts are so proportioned and arranged as to rigidly connect the same, so that the flexure which occurs when two coupled cars are rounding a curve takes place at the hinged connection between the couplers and the cars.

The tailpiece C of each knuckle projects rearwardly into the hollow head of the couplers, as clearly shown in Figs. 1, 2, and 6, and is locked in its closed position by a lock-arm D, which is rigidly attached to a horizontal rockshaft D, extending transversely beneath the head and rotatively mounted in depending lugs or ears 6 6 formed on said head, as more clearly shown in Figs. 2, 4, and 5. Said lock-arm D extends upwardly into the rear end of the hollow head through an opening in the bottom wall thereof and when in its looking position is located inside of the tailpiece C of the knuckle, and therefore in the path of the knuckle, so as to prevent said knuckle swinging outwardly on its pivot 6. The said lock-arm D is shown as made separated from the rock-shaft and is provided at its lower end with a transverse aperture through which the rock-shaft extends, and the rock-shaft is provided with a radial lug d, (more clearly shown in Fig. 2,) which fits acomplemental socket in the arm, intersecting its transverse aperture, whereby rotation of the arm on the shaft is prevented. One of the ears or lugs 6 in which the shaft is mounted, is provided with a notch 5 as shown inFig. 5, through which said lug (Z of the rock-shaft may pass when inserted in place. The lock-arm of the rockshaft is given a normal tendency to swing forwardly with its upper end in the path of the tailpiece of the knuckle when the knuckle is closed, by means of a spiral spring D which surrounds the rock-shaft and bears at one end against the coupler-head and at its other end against the lock-arm, as shown in Fig. 4. The forward wall of the opening in the coupler-head through which the lock-arm D extends upwardly constitutes a stop which limits the forward throw of the lock-arm. Such tendency of the lock-arm to swing forwardly may be accomplished by the equivalent expedient of weighting or overbalancing the arm in a manner to bring the center of gravity forwardly of its pivot.

The lock-arm is swung rearwardly from its locking position by rocking the shaft D in its bearings, and this is effected in this present instance by means of cranks D attached to the opposite ends of said rock-shaft, said rock-shaft being extended sufficiently beyond the coupler-head, on each side thereof, to be readily accessible for the purpose of throwing the lock-arm backwardly when the coupler is in place upon a car. The lock-arm is swung into its unlocking position against the action of the spring D by manual force applied to the cranks D and when such manual force is released the spring D throws or tends to throw the lock-arm forwardly into the path of the tailpiece of the knuckle, as shown in full lines in Fig. 2, and therefore in its locking position.

The coupler is provided with an interior web or partition B, located on the side of the lock-arm opposite to the rear end of the tailpiece of the knuckle when the latter is closed and extends, as herein shown, from the upper to the lower wall of the hollow draw-bar. Said web or partition constitutes an abutment against which the said lock-arm 1) is laterally pressed by the tailpiece of the knuckle to resist the opening movement of the knuckle when said lock-arm is in its locking position. Said web or partition B, as herein shown, is a rearward continuation of the inner wall of the shank of the hook B. The abutment afforded by said web or partition may be afforded by other constructions.

The lock-arm D is adapted to be set or locked in its rearward or unlocking position by means of a generally horizontal verticallyswinging latch E, which is pivoted at its rear end to a horizontal pin E, which extends transversely across the draw-bar in rear of the coupler-head. Said latch is provided on its under face with a detent 6, Fig. 2, which is adapted to engage the forward upper corner or other part of the lock-arm when the latter is thrown in its rearward position, as shown in dotted lines in Fig. 2. When said lock-arm is locked in its rearward position by the latch E, the tailpiece of the knuckle is free to pass said arm to permit the knuckle to open. The detent of said latchis provided at the side thereof adjacent to thetailpiece of the knuckle when the knuckle is closed with a downwardly and laterally oblique face e. When the lock-arm D is in its locking position, as shown in full lines in Fig. 2, the detent bears upon the upper end of the lockarm, which holds the same above the level of the upper face of the tailpiece of the knuckle. When said lock-arm is swung back wardly into its unlocking position and is set or held in such position by the latch, the detent of said latch drops downwardly inside of the tailpiece, with its inner end below the level of the upper face of the tailpiece of the knuckle, as shown in dotted lines in Fig. 2. After the lock-arm is set, therefore, in its unlocking position and held therein by the latch and when the knuckle is opened the tailpiece in swinging inwardly strikes said oblique surface 6 on the detent of the latch and raises the latch sufficiently to disengage the latch from said lock-arm. When the lock-arm is thus released, it swings forwardly under the action of its spring D against the outer curved face C of the tailpiece, which at this time is located in front of said lock-arm. During the time the opening movement of the knuckle occurs and while it stands open said lock-arm bears against the said curved outer face (1 of the knuckle-tailpiece, and when the knuckle is again closed said tailpiece forces the lock-arm backwardly as it closes until it has passed said lock-arm, whereupon said lock-arm is swung into the path of said tailpiece and locks the knuckle in its closed position. The tailpiece does not swing the lock-arm backwardly sufficiently during the closing movement of the knuckle to engage the upper end of the arm with the detent of the latch in a manner to set or look the arm.

The tailpiece of the knuckle is provided on its upper outer corner with an upwardly and laterally facing oblique surface 0, which engages the forward end of the latch during the closing movement of the knuckle, so as to raise said latch out of its way in case the forward end of the latch be dropped below the level of the upper face of the tailpiece.

When two connected couplers are to be uncoupled or disconnected, the lock-arms of both couplers are swung into their rearward or unlocking positions and locked or set by their latches E, so that when the cars with which the couplers are connected are separated the knuckles are free to open. During the opening movement of said knuckles the tailpieces thereof strike the oblique faces a of the latches and raise the latter sufliciently to release the lock-arms, whereupon the latter are swung forwardly by their springs D against the outer curved faces C of the tailpieces of the knuckles and remain in this position so long as the knuckles are open. When the knuckles are closed, the outer laterally-curved faces 0 of the tailpiece, against which the lock-arms bear, swing said lock-arms rearwardly until the tailpieces pass said arms, at which time the arms are swung forwardly into the paths of said tailpieces to lock the knuckles closed. If after the knuckles have been opened the latches are swung backw'ardly and are set or'loeked in their rearward positions and the detents at the forward ends of the latches are therefore below the level of the upper faces of the tailpieces of the knuckles, the oblique faces 0 of the tailpieces strike said latches and raise them, so as to allow the tailpieces to pass freely thereunder and also to release the lock-arm, whereupon the lockarms swing forwardly against the side curved margins (J of said tailpiece in the manner before stated.

The coupler herein shown is designed to be used with other forms of couplers now in common use and is shown in Fig. 6 as connected with the Van Dorn type of coupler F. In order to provide for such adaptation of my coupler, the coupler-head is provided with a forwardly-directed opening 6 through which may be inserted a suitable form of link G, and which link extends sufiiciently beyond the end of the coupler to engage the coupler F. The opening 6 herein shown is provided in the inner wall of the shank B of the hook B, said opening being made of sufficient width to receive the rear end of the link and permit a limited swinging movement thereof. Said rear end of the link is' apertured to receive avertical pivot or hinge-boltG, which extends vertically through an opening 6* in the upper and lower walls of the coupler-head.
