This invention relates to an improved form of water closet, for 

 sliipping, and which is alsj applicable for dwelling-houses, where the 

 sewer or outlet may be a'lOiie the water c'.oset. Fig. 1 is a section, 

 and fig. 2 a siile view, of a water closet with the improvements. The 

 bisin is supported upon a fluiged elbow piece /, ami bolted to a ho- 

 rizontal pump or piston birrel G, terminating in a delivery piece ^. 

 Within the elbow piece /, there is a vaive, opening towards the pis- 

 ton barrel, which valve is fitted and dropped into its place upon a 

 S'-ating, as shiwn in the drawing, previously to the basin being fixed. 

 Within the piston birrel G, there is a piston, furnished with a valve, 

 opening towards the d.-livery en.l of the barrel ; this piston is worked 

 bv two horizontal pislon-rods, passing through stulling-baxes, — only 

 one is seen in fig. 1, but the ends of b.ith are shown in fig. 2. On the 

 upper part of the delivery piece g, there is a valve, opening outwards 

 towards the second delivery piece h, upon which an union screw is 



cut, for the attachment of a soil pipe, which mar be taken to the 

 most convenient point (either above or below the water-hne), for 

 delivering the matters ejected by the piston. L is the handle, work- 

 ing through a slot in the seat of the closet, by which the action of the 

 closet is effected, through levers and connecting rods, working the 

 horizontal piston-rods, and also for giving motion to a rod which 

 opens and closes the cock B ; this cock communicates with the water 

 on the outside of the ship by a pipe on its under side, and with a 

 reservoir or cistern pipe (A) above, and also with the basin of the 

 closet. On raising the handle L, motion is given to the cranked 

 levers, which causes the piston with the valve to traverse in the 

 barrel G, as shown by the dotted lines (fig. 1), and expel vvhate ver 

 substances liave passed through the valve. The m ,tion of the levers 

 will at the same time open a communication with the pipe A, the 

 contents of which will rush down iuto tue basin. On pressing down 

 the lever, the piston will retrogade in the barrel G, and whatever 

 substances have passed the valve/, will be forced through the valve 

 in the piston, into the piston barrel, and be ejected bv the nest motion 

 of the piston. The connection with the extern d water will, by 

 the same movement, have been opened, and the pipe A will become 

 filled ready for ringing the basin on the next movement of the pump. 

 In order that the pipe A, may perform the office of an elevated reser- 

 voir or .•istern, it should be from two to three teet higher than the 

 top of the basin; it is fitted with a floating au-valve at its upper end, 

 which is closed by the rising of the water when the pipe is filled, but 

 opens and admits'air when the pipe is discharging its contents into 

 the basin. The pipe must be of such capacity as to hold the quantity 

 of water required for the use of the basin. The patentee prefers a 

 ? inch diameter), and leads it in a convoluted or zig- 



small pipe (say S ...» . - 



zig form, as shown in the engraving, so as to maintain a head ot 

 water as long as possible, to give the necessary force to the jet pass- 

 inn- through Uie fan. If the watercloset is to be fixed in a ship, so 

 that its seat will at any time be less than two feet below the level of 

 the external water, the water will not rise high enough in the pipe A, 

 to acquire sufficient force by Us gravity to cleanse the basin. In such 

 cases the supply of water is to be drawn by means of a small lorce- 

 pump or pumps worked by the lever, as shown in fig. 3 ; these pumps 

 drive the water through a pipe earned up one loot or more higher 

 than the level of the external water line, so as to guard agaiust any 

 undue influx of water through the pump valves.
