is formed by casting a flange or rim upon the plate of the closet, 

 within which is an opening of about one inch, which is tapped, 

 and into which the valve cock, A, is firmly screwed : beneath the 

 plate is arranged a lever which is suspended by the screw D, (the 

 screw^ passing through the lever into a brass nut.) The journal 

 upon which the pan is hung is provided with a cam, cast upon it 

 near the front bearing, and upon lifting the handle of the closet, 

 the cam forces down one end of the lever, lifting the opposite end 

 about one-half inch. The stem or spindle of the valve projects 

 down through the bottom of the cock, below^ the plate of the 

 closet, and rests upon the lever, and is lifted when the pan is dis- 

 charged. The screw D, upon which the lever hangs, is used to 

 regulate the lifting of the valve, and thus, by turning the screw 

 to the right or left, the valve is made to discharge more or less 

 water into the pan after the handle is dropped. The construction 

 of the valve is such that it will properly fill the pan after it is 

 discharged and in place, however rapidly the pan is opened and 

 shut. This screw will admit of being turned so far to the left as 

 to let the lever drop so low, that in case the pipes and valve 

 should freeze, the closet can be used, without lifting the valve 

 open. The w^ater is conducted from the main pipe, or from a 

 tank upon the house, directly through the valve, in the direction 

 indicated by the arrow on the body of the cock, to the basin. No 

 intermediate receiver, or waste pipe, or air vessel being required, 

 and no jarring of the pipe is produced, the pipe C wasting directly 

 into the closet. The valve is arranged so that but little pipe is 

 required to connect it with the main or the basin. The working 

 parts of this valve can all be taken out by simply unscrewing the 

 screw cap, and without disturbing the body of the valve, or either 

 of the couplings. The valve being in reversed position, the 

 leather lacing shutting downward is likely to prevent any obstruc- 

 tion by lead chips, dirt, &c. 



The peculiar construction of this valve is such, tliat however 

 rapidly it may be opened, it always suspends itself open a suflS.- 

 cient length of time to admit an " after-supply" of water into the 

 pan to fill it properly — and gives a continuous supply while the 

 handle of the closet is lifted. 



This valve, of a different form and modification, is adapted to 

 the purpose of hopper closets, being operated by pressure upon
