I avoid these objections coupling, parts being in horizontal section and at the same time provide a construction and parts broken out, illustrating the valve wherein the valve is automatically operated in open position.

Fig. 7 is a longitudinal sectional view taken Reference-sign 14 designates a stub pintle on the line at 00, Fig. 6, and looking in the dior shaft, having a suitable bearing formed in rection of the arrows. Fig. 8 is aplan viewof the casing of the half-block adjacent to the mouth formed in the engaging face of the halfblock.

15 designates a valve, preferably circular in shape and of suitable material and corresponding to the mouth of the opening in the engaging face of the half-block. This valve is carried by an arm or lever 16, suitably sleeved or otherwise mounted upon the pintle or shaft 14. Suitably mounted upon the other end of said pintle or shaft 14 is an arm 17, provided at its outer extremity with an upturned end, as shown, (see Figs. 4: and 9,) arranged to project up into a recess 18, formed on the under side of a plate 19, movably mounted and arranged in position to be engaged by the engaging lip or projection on an adjacent half-block when a coupling or an uncoupling is effected and to be moved thereby, whereby the upturned end of arm 17 is engaged by the walls of recess 18 and said arm rocked. .It will be observed that

arms

16 and 17, being rigidly secured to pintle or shaft 1%, constitute in effect a double crank, and when arm 17 is rocked a rocking of pintle or shaft it results, and hence a swinging of arm 16, carryin g valve 15, is effected, thereby swinging the valve 15 away from or into position to cover the mouth of the opening in the coupling block.

In order to provide a construction wherein the valve 15 may rock about a central axis, whereby it can the more readily be slid into its closing position, and in order to permit a slight motion of the valve relatively to its supporting-arm, whereby it may be acted upon by the pressure contained in the trainpipe to more closely fit its seat, I provide the valve end of arm 16 with a perforation. To the valve, and preferably centrally thereof, is suitably secured a pin 20, slightly longer than the thickness of the end of the valvecarrying arm and adapted to be received loosely in the perforation in the end of said arm. By this construction the valve may freely rotate Within the socket formed in its supporting and carrying arm and at the same time be permitted a movement transverse thereto.

It will be understood that the pintle or shaft 14 is arranged adjacent to the mouth of the half-block, and the end upon which arm 16 is mounted is arranged to project into the body or the space forming the chamber of the halfblock, and that the arm 16 and valve are also arranged within this space. In the constructi on shown the pintle or shaft is arranged with reference to the mouth or opening in the engaging space of the half-block, so that the arm 16, and hence the valve 15, is rocked in a plane parallel with the engaging face of the half-block; but I do not desire to be restricted to this particular location and arrangement, as many other forms and arrangements of mechanism would readily suggest themselves to persons skilled in the art and still fall within the spirit and scope of my invention.

In order to suitably support and guide the sliding plates 19, I provide said plates with a flange adapted to bear against and to be received by the wall of the half-block formed by the projecting lip 12, as shown. (See Figsf 4 and 9.) This flange is preferably curved, as shown, to correspond with the curved wall and also to the path of travel of the engaging lip upon an adjacent half-block when two half-blocks are rocked to effect a coupling. At the respective ends of said plate 19 I provide upturned ends 21, and said plate is constructed of a length sufficient to receive between its upturned ends the engaging lip upon an adjacent half-block, as will be readily understood by reference to Fig. 2, and said plate is adapted to rest upon the top portion of the horizontal face of a half-block. In order to avoid obstruction to the free movement of said plate, and at the same time in order to secure compactness, I provide a recess 22 in the seat of said plate in the face of the horizontal portion of the half-block, said recess or countersink adapted to receive therein the arm 17. (See Figs. 4 and 7.) The plate 19 is designed to fit in its seat snugly and to be held by frictional contact therein in any position in which it may be moved. If desired, however, in order to impart additional friction thereto, I may, when necessary, mount a small leaf-spring 23 upon the casin g, forming the covering for said plate and arranged to bear against said plate in any suitable manner. (See Fig. 5.)

It will be understood from the above construction that when two half-blocks are placed in position to effect a coupling up as, for instance, as shown in Fig. 2a flange or projection 13 of one block rests between the upturned ends of the sliding plate 19, it being understood that When the parts are in the position shown in said figure the valve is in its closed position. WVhen the half-blocks are rotated upon each other to effect a coupling up, the edge of the lip 13 engages the upturned end of the plate when the half-blocks have been rotated upon themselves a sufficient distance, and thereafter the sliding plate moves with the engaging lip or projection. At the beginning of the movement of the sliding plate 19 the upturned end of arm 17 occupies a position in the countersink or recess 18, formed in the under side of the sliding plate adjacent to the inner edgetor wall of said recess or countersink, as indicated in dotted lines in Fig. 6. After the sliding plate moves a distance equal to the length of said countersink or recess said upturned end is engaged by the outer wall of said countersink or recess and is moved thereby to effect a rocking of the arm 17, pintle or shaft 14, arm 16, and hence a swinging of the valve from its closed to its open position, as indicated in Fig. 5. A reverse movement of the half-blocks effects a movement of the sliding plate in the opposite direction, and hence effects a closing of the valve. It will be understood that when the valve is in its open position, as shown, for

port moves bodily to cover or uncover the mouth of the half-block, the valvesupport being arranged out of line with said mouth. By this arrangement the entire area of opening of the mouth of the half-block is covered or uncovered by the valve.

I am aware that it is not new to provide a rotary valve having a port-opening therein and adapted to be rotated to cover or uncover a port-opening formed in a disk, which disk is arranged in the mouth of the half-block, as shown, for instance, in Patent No. 214,336,

dated April 15, 1879, to Westinghouse, and

therefore I do not claim such construction.

In some cases it may be desirable to provide a construction wherein the engineer is notified in case of a malicious uncoupling of coupling-blocks constructed in accordance with my invention. I11 other words, it may be desirable to place the valve mechanism of the coupling-block under the automatic con I have shown in Figs. I

trol of the engineer. 8, 9, and 10 a construction for accomplishing this result. In this construction I slidably mount the arm 16, supporting the valve 15, upon the end of pintle or shaft 14, and provide a suitable clutch whereby, when the sleeve or hub of the valve-carrying arm is in one position, it is rigidly secured to rock with the pintle or shaft, but is released therefrom to, permit said pintle or shaft to rock loosely therein in another position of said sleeve. This clutching may be effected in a convenient and simple Way by providing a pin 23, passing transversely through the pintle or shaft and having its projecting ends adapted to be received in suitable slots or seats provided in the hub or collar, as shown, when said hub or collar is moved into the proper position, the said hub or collar being adapted to slide along said pintle or shaft to effect a disengagement of said pin. In order to effect this sliding movement in a simple way,

and at the same time to place this clutching or unclutching under the control of the e11- gineer, I provide the following construction:

WVithin a portion of the casing forming the coupling-block I mount a sleeve 24, comprising an open-ended cylinder, theend of said cylinder projecting into the body or space formed by the casing, forming a valveseat adapted to receive a sliding piston 25 therein, said piston being arranged within said sleeve and having a stem 26 projecting through the opening in the end of said cylinder and into the interior of the half-block chamber. An arm 27, carried by said stem, is provided and arranged to engage the hub of arm 16. By this construction it will be seen that when the piston 25 is moved in one direction the hub of valve-carrying arm 16 is moved in a direction to effect a coupling or clutching of said hub to the shaft or pintle 14:, and when said piston 25 is moved in the opposite direction an uncoupling of said hub to said pintle or shaft is effected. I mount a suitable spring within the sleeve 24 and arrange said spring to bear against piston 25 to normally seat the same, a screw-plug 29 being arranged to close the outer end of said sleeve and to receive the thrust of said spring. The arrangement is such that when the piston 25 is seated the hub of valve-carrying arm 16 is unclutched from pintle or shaft 14. The tension of spring 28 is so arranged as to be slightly in excess of the normal pressure in the train-pipe, whereby the valve carrying arm 16 is normally unclutched. When, however, the pressure in the train-pipe is increased by the engineer suitably manipulating his pressure-controlling apparatus, the tension of spring 28 is overcome, piston 25 is raised from its seat, and a clutching of valvecarrying arm 16 to shaft 14 is effected. It will be understood that when valve-carrying arm 16 is uncoupled from :shaft or pintle let the position of valve 15 is not effected by a coupling or uncoupling of the coupling-block, for in that case any rocking motion imparted to shaft or pintle let will not be imparted to the valve-carrying arm.

The operation of this part of my invention is as follows: Assuming that the train is coupled up and that there is normal pressure in the train-pipes, under these conditions it will be understood from the foregoing description that, inasmuch as the tension of spring 28 is designed to be in excess of the normal train-pipe pressure, piston or plunger 25 will be seated, thereby unclutching the valve from its operating-shaft 14, and since the act of coupling up has moved the valve to its open position it is retained in that position and cannot be seated until again clutched to its actuating-shaft. Now, if an uncoupling is desired, the engineer admits abnormal pressure to the train-pipes sufficient to overcome the tension of spring 28, thereby causing the piston or plunger 25 to be moved in a direction to effect a clutching of the valve to its operating-shaft, and then the act of uncoupling effects a closing of the valve. If an unauthorized uncoupling is made while the valve isunclutched, the engineer is immediately notified by the setting of the brakes and by the fall of pressure, as indicated by his pressure-gage, due to the escape of air through the open mouth of the coupling-block. hen a car is added to the train, the act of coupling up the hose-pipes opens the valves. If the equalization of pressure in the train-pipes is not suflicient to reduce the pressure to the point where the piston or plunger 25 is released, the engineer reduces the train-pressure sufficiently to permit the spring 28 to again unclutch the valve. If desired, a suitable retaining-pin (see Fig. 8) may be provided to retain the valve in its open position when uncoupled from the operating-shaft 14:.

I will now describe the construction and operation of my improved means for securing removably the gasket in place in the mouth of the opening formed in the face of the coupling-block, whereby said gasket maybe easily and readily removed and new ones inserted for repairs when desired or required. Reference-sign 31 designates the gasket, 32 a circular ring arranged to hold said gasket to its seat, and 33 arms secured to or forming part of said rings and constituting a spider. Suitably j ournaled in said arm is a cam-block 34, of suitable construction and arrangement, adapted to bear against the back walls or roof of the valve-chamber (see particularly Figs. 4;, 7, 9, and 10) and adapted when turned in one position-as, for instance, in position shown in said figuresto force said spider and ring against the gasket to hold the same in place, and at the same time to maintain said cam block or lever in a fixed position, said cam block or lever being so constructed that when suitably manipulated or rocked about its pivot the pressure upon the gasket may be relieved, the ring 32 being withdrawn therefrom, thereby permitting the removal and renewal from the face of the half-block of said gasket, as will be readily understood.

In order to provide a compact arrangement of parts, the inner upturned end 21 of plate 19 maybe grooved, as at 35, to receive therein the usual binding or clamping screw or rivet 36. (See Figs. 3, 5, and 6.)

If desired, the clutch-pin 23 may be employed as a means for holding the packing 37 for the valve-operating shaft or pintle 14. (See Figs. 9 and 10.)

Having now fully described my invention, its objects, purposes, and function, and the principle thereof, and having fully set forth a form of mechanism embodying the same, and having explained the principle and mode of operation thereof, I desire to be understood that I do not desire to be limited to the specific details of construction and arrange ment shown and described, as many variations therefrom may be readily made by persons skilled in the art and still fall within the scope of my invention; but
