the seat-board, giving a supply of water into the hopper only 

 after the pressure upon the seat has been removed, using water 

 economically, requiring no air vessel, nor jarring the pipe — the 

 whole arranged beneath the seat. 



Figure 2 is a drawing of an improved Hopper closet, with the 

 Bartholomew Patent-Self- Acting Valve attached. This hopper 

 of the most approved form in use — cast iron, either enamelled or 

 plain — having a broad flange, firmly braced, cast upon it, by 

 which the hopper is substantially secured to and supported 

 entirely by the floor, without requiring any riser or wood work 

 about it to support it. A projection is cast upon the rear upper 

 end of the hopper, to which a board of six inches width is screwed, 

 and to this board the seat-board is hinged, having a weight 

 attached so as to keep the seat-board in an upright position when 

 not in use, as shown in drawing, by which the hopper may be 

 used for a urinal or slop sink, and yet the seat-board always kept 

 dry and clean. The valve is held open when the seat-board is 

 held down, and closes upon the rising of the seat. It will be seen 

 that no carpenter work or wood is required about this hopper, 

 except the seat-board and floor as shown — thus giving facilities 

 for keeping the premises clean and pure — avoiding the nuisance 

 of confined foul air and filth which attend the fixture when 

 closely shut up. This improvement is well adapted to hotels, 

 schools, hospitals, and other public, as well as private buildings.

This valve has a leather or rub-
