CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 411,216, dated September 17, 1889.

Application filed February 9, 1889. Serial No. 299,230. (No model.)

f (Ml whom it may concern:

Be it known that I, JOHN A. DEAN, of North Ogden, in the county of eber and Territory of Utah, l12t"6 invented new and useful Improvements in Gar-Couplers, of which the following is a full, clear, and exact description.

This invention relates to ear-couplers, the main object of the invention being to provide a coupler which shall be automatic in its action of coupling, and one wherein the parts are so arranged that the cars may be uncoupled by throwing a lever, which may be located in any convenientposition, a further obj eat of the invention being to dispense with the ordinary tubes employed in the operation of steam or air brakes by so constructing the coupler and the coupling-link that a passage will be established through said couplinglink, all as will be hereinafter more fully explained, and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a side view of a pair of my improved coupl'ers, the coupling upon the right being shown in central longitudinal section. Fig. 2 is a plan view of the coupler shown in Fig. 1, the upper portion of the right-hand coupler being removed. Fig. 3 is aninverted plan view of the coupler, the lower portion of the right-hand couplingbeing removed. Fig. 4: is an end view of one of the couplers, the coupling-link being shown in section. Fig. 5 is an inverted plan view of a coupler, repre senting the same as it appears when applied to a car. Fig. (3 is a perspective view of one of the coupling-jaws and Fig. 7 is an enlarged detail view of a portion of the coupling-link and a portion of the coupler, one-half of the parts shown being represented in section.

In the drawings, 10 represents the drawbar plate, which is provided with two downwardly-extending wings 11, formed with longitudinal slots 12, the wings being braced by two centrally-apertnred cross-plates 13 and let. To the forward end of the plate 10 there is secured a downwardly-extendin g apertured bracket 15, through which the draw-bar 16 passes, the forward end of the said draw-bar being rigidly connected to the draw-head 17, while the body of the draw-bar passes through an apertured boss 18, which extends upward from the rear end of the draw-head.

Draw-ioar follower-plates 19 are mounted to ride between the wings 11, said draw-bar follower-plates being formed with lugs which enter the longitudinal slots 12. Between the follower-plates 19, I arrange a buifer-spring 20, said spring abutting against the two plates. The draw-bar 16 is provided with a head 21, or with a key that is passed through the body of the draw-bar beyond the rear draw-bar follower-plat e. f

The draw-head 17 is preferably made in two sections a I), said sections being bolted together, as shown in the drawings, and between these two sections I mount jaws 22, in the inner faces of which there are formed re cesses 0, adapted to receive the knobbed wings (I of an arrow-headed coupling-link 30. In connection with each of the jaws 22, I arrange springs 23, which carry anti-friction rolls 2d, the rolls bearing against the outer faces of the jaws and holding them in the position in which the jaws are shown in Fig. 2.

In order that the jaws may be drawn outward to free them from engagement with the wings of the coupling-link, I secure to each jaw a chain or rope 25, which passes about a sheave 26, that is secured to the under side of the car-body, the other ends of the chains or ropes 25 being secured to opposite ends of a lever 27, that-is pivotally connected to the under side of the draw-head section Ct. To one of the ends of the lever 27, I connect a third rope or chain 28, which in turn is 0011- neeted to a lever 29, the arrangement being such that by throwing the lever in the direction of the arrow shown in connection therewith the jaws 22 will be drawn out to the position indicated by dotted lines in Fig. 5, all undue outward movement being prevented by limit-staples 31, that are arranged as shown in the drawings.

Such in general is the construction of my car-coupler, the arrangement being such that when two cars provided with the coupler approac'h, one of the couplers carrying the coupling-li11k,'tl1e free end of said coupler will enter the mouth of the draw-head of the opposing coupler, and the wings of the arrowhead of the link, striking against the inclined faces 6 of the jaws 22, will force said jaws apart until the knobbed wings enter the jaw-recesses 0, thus leaving the springs 23 free to force the jaws to the position shown in Fig. 2, thereby coupling the cars.

In order that the free end of the couplinglink 30 may be prevented from sagging, I mount a plate 32 in the draw-head recess, said plate being depressed by a spring 33, and this plate, in case the coupler was not provided with the air or steam brake attach- 111ent,would bear upon the arrow-head of the link.

If it should be desired to utilize the coupler above described for the purpose of establishing the necessary connection between the locomotive and the car-cylinders of an air or steam brake system, I would form the coupling-link with a central bore f, and within each of the draw-heads I would mount a socket 40, formed with a concave receivingface g, of a contour adapted to fit closely against the end h of the coupling-link, there being a bore formed in the said socket which leads to a rearwardl -extendin stem 41 said.

stem being formed with a head 42 and with a branch stem 43, to which the couplingtubes may be connected. III'IHOUHtIHg the socket I coil a spring n about the stem 41, one end of the spring abutting against the rear face of the socket, while the other abuts against the draw-head, as shown best in Fig. 1, the action of the spring being to throw the socket forward. At either side of the socket I mount jaws 44, which are normally held in the position shown in Fig. '7 by springs 45, that are arranged at the j aw-heels, these jaws entering recesses 2' in the link-heads h and holding said heads firmly against the packing 7.0, that is fitted in the socket.

I11 order that the jaws 44 may be thrown outward to the position indicated by dotted lines in Fig. 7 at the time when the jaws 22 are opened to release the link 30, I pivot tongues 46 to each of the jaws 22, said tongues riding in recesses formed in the draw-head and being arranged so that when the jaws 22 are moved to the position indicated by dotted lines in Fig. 5 the tongues 46 will bear against the heels of the jaws 44B and throw said jaws outward and away from the link-head h, it being understood that at the time the uncoupling of the cars takes place the springs 72 will be compressed, so as to bring the socket-heads 40 into proper position to be borne upon by the tongues 46.

By means of the coupler above described I provide for communication between the engine and the operating brake-cylinders without the necessity of having independent connecting-tubes between the cars.

It will be noticed that the head of the link 30 is quite broad, consequently provision must be made for the rocking of the cars, and it is to provide for this rocking that I have arranged the coupling-head, so that it will be free to turn upon its connection with the carbody.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with a separate and independent link formed with a continuous bore, of a coupler arranged to engage said link, and sockets adapted to receive the link ends, substantially as described.

2. The combination, with a link formed with a continuous bore and with recessedheaded ends, of couplers adapted to receive said link, sockets adapted to receive the link ends or heads, and jaws carried by the sockets, said jaws being arranged to enter the link-head recesses, substantially as described.

3. In a car-coupler, a coupling link 30, formed with headed ends h h, and laterallyprojecting knobbed wings d between said heads, the link having a longitudinal bore from end to end, substantially as set forth.

4. In a coupler, the combination, with a draw-head, of jaws pivotally mounted therein, springs arranged in connection with the jaws, means for drawing out the jaws, tongues carried by the jaws, and a socket adapted to re ceive the headed end of a coupling-link and provided with jaws arranged to engage said head, substantially as described.

5. In a coupler, the combination, with a plate arranged for connection with thecarbody and formed with a downwardly-extending apertured lug or projection 15, of a drawbar which passes through the aperture of said lug or projection, a draw-head rigidly connected to the forward end of the draw-bar and formed with an apertured lug through which the draw-bar passes, and springs and follower-plates arranged in connection with the draw-bar, substantially as described.

6. In a car-coupler, a draw-head 17, having opposite longitudinal slots in rear of its outer end or mouth, outward-swinging hookedjaws 22, pivoted at their rear ends in the inner ends of said slots, and springs 23, pressing said jaws inwardly, substantially as set forth.

7. The combination, with a draw-head having opposite inner and outer jaws, of a link having headed ends to engage the inner jaws, and laterally-extending wings between said heads toengage the outer jaws, substantially as set forth.

8. The combination, with the draw-head having coupling-jaws, and a longitudinallyyielding socket in rear of said jaws and a tube or pipe connected therewith, ofa longitudinally-bored coupling-link having its ends constructed to engage said socket and provided with wings to engage said jaws, substantially as set forth.
