I hang also within the cupboard and from the upper portion of the cupboard frame the coiled spring K and from I which is suspended the forked clutch .lJ. The chain J extends down through the bottom of the cupboard or out ofthe cupboard, and has connection With the rod M which extends down through the floor of the car coin necting with the bifurcated lever N. The bifurcated lever N is forked at the point 0 and divided into two arms N and N. I These arms N and N have hinged connec- To all whom it may concern:

Be it known that 1, UnAnLEs W. PEAR- SALL, a citizen of the United States, residing State of New York, have invented certain new and useful Improvements in- Water- Closet Valves for Cars, of which the following is a specification. l My invention relates to im )rovements in j valves for water closet-s in rai road cars, and in which a hinged valve controlled by a coiled l spring is operated by means of a hinged lever l extending up through the bottom of the car and connecting with a forked spring clutch mounted within a closet cupboard or locked tions P and P with the closet valve B. When in its normal position the valve'B being open, the door of the cupboard Q is closed and locked.

W hen it is desired to close the closet valve, the operator unlocks the door Q and opens it. He then draws the lever chain J over the pulley G and thus raises the lever rod M and its hin edconnecting rodN until the closet valve is c osed and drawn up by the forked lever arms N and N. Having thus drawn up the hinged valve B, he then draws down the s ring clutch L attached to the coiled spring 1% as shown in Fig. 4 until this coiled spring is at a stiff tension. Then he pushes in the spring clutch L against the guard. chain J until the guard chain J is thus firmly held by the clutch fork arms R and S as shown in Figs. 1, 2, 4, and thus the chain is lirmly held and with it the lever arm M in a firm yielding tension drawing up tightly the closet valve B. The door Q is then closed and locked and thus preventing any interference with the closed closet valve while the train is standing at a station. And it is my design and plan that the cupboard or locking compartment ll shall be mounted or constructed in any convenient place on or in a wall of the car, so that the door Q can be opened and the valve operated even though the car closet is occupied by a passenger. On the train leaving the station the guard unlocks the door Q, releases the clutch L from the chain G whereupon the lever rod M drops down and thevalve B opens and swings back to its normal position as shown in Fig. 1.

Thus having fully described my invention, What 1 claim as new and for which l. desire Letters Patent is as follows:

1. In combination a railroad car closet The objects of my improvement are to provide an easily operated stop valve for a railroad water closet, so as to readily and com. pletely close the outlet of the closet while the car is standing at a station, and thus do away with-tho necessity of locking up the closet; but permitting it to be freely used by the passengers, yet at the same time roviding a closing and o ening means, capalii le of being used and un er the control of the railroad employees; while at the same time it is comlctely guarded against being used or inter fered with by the passenger or public. I attain these objects by the mechanism illustrated in the accompanying drawings in which Figure 1 is a perspectivewiew of an operative portion of my devicc.- Fig. 2 is a perspective view of a detached portion of my device. Fig. 3 is a horizontal plan view of the valve crtion of my device. Fig. 4 is a detache portion of my device showing its connecting parts in operation.

Similar letters refer to similar parts throughout, the several views.

A represents an ordinary water closet seat and bowl in a railroad car. At the lower end of the outlet pipe I have the stop valve B atthe hinge C. This valve consists of a round plate to which is attached a rubber or other yielding surface T. This valve B is held in an o' in position as shownf i by means of tli coiled spring D shown in r 1 extcnding from the projection E on the side of the closet outlet to the projection i at th ark of the closet valve. Imount wi thin th set, or outside the closet the pulley l} hung with in the cupboard H by the pulleyhangerl. The cup l extending into the the mouth of the chute, a spring for normally keeping valve open, a compartment, means for lock- 1 ing the same, actuating members for the valve compartment and means in the compartment cooperating with said; members to hold the valve in closed position.

2. In combination, a railroad car closet seat chute, a valve for closing the mouth of the chute, a spring for normally holdin the valve open, a compartment, means-for ocking the same, a pulley in said compartment, a chain passing over said pulley and out of the compartment, rods connecting the chain with the valve'and means in said compartment engaging with the chain for locking the valve in closed position.

3. In combination a railroad closet seat chute, a hinged valve attached to the chute near the mouth of the same said valve having a rubber or other yielding surface on its face and so shaped and positioned as to fit over themouth of. the chute when closed against the mouth, said valve being held open in its usual position by ,means of a s iral spring connection between the valve an the side of the chute ,'a series of hinged rods terminating said rods he hinged in a chain connection with a pulley; having 'a hinged connection with t valve by meansof two arms in hinged'conneetion with the valve;
