GEORGE C. STONE, OF CHICAGO, ILLINOIS.
IMPROVEMENT IN WATER-CLOSETS.
Specification forming part of Letters Patent No. l 51,933, dated June 9, 1874; application filed March 17, 1874.
Chicago, in the county of Cook and State of Illinois, have invented an Improvement in Vater-Closets, of which the following is ak specification This invention relates to an improvement in that class of water-closets wherein the tilting bowl is attached to a removable portion of the hopper or container, and relates to thc combination with the water-valve of a supplementary valve for preventing the main valve from suddenly closing with violence upon releasing the pull-up lever.
Figure 1, Sheet 1, is a perspective view of the hopper and its attachments. Fig. 2 is a similar view, but without the bowl and removable plate ofthe hopper. Fig. 3, Sheet 2, is a cross-section. Fig.' 4 is a perspective view of the inner part of the removable plate and bowl attached. Fig. 5 is an enlarged horizontal section of the valve and casing. Fig. 6 is aperspective view of the same.
in the drawing, A represents the hopper or containerf which is a cast-metal shell in the general form of an oblate spheroid, with an opening in the bottom, surrounded by a flange which sits over the soil-pipe. There is a circular opening in the top, surrounded by a flange, a, upon which the basin (not shown) rests. The upper part of one end or side of the shell is cut away below the flange a, the opening so made being closed by a plate, A', as seen in Figs. l and 3, which is secured by a thumb-screw, b, tapped through its lower edge into a projection, c, cast in theinner wall of the container. B is the tilting bowl, secured to an arm on the rock-shaft C, the i11- ner end of which is journaled in a bracket, d, cast in the plate A', while the other end projects through a bearing, e, in the edge of the container, with a slotted crank, D, secured to its outer end. E is the operating-lever of the closet, pivoted at the forward end to a pair of lugs under a bracket-tray, F, cast on the container. At its rear end is the weight, and a slotfor attaching the pull-up rod. (Not shown.) A single bolt, f, and nut, passing' through the slot ofthe crank D, connects the latter with a heel or offset, g, in the lever. By removing the bolt f and the thumb-screw b, the plate A' and the bowl may be detached from the container without being obliged to disconnect all the other levers, joints, arms, 8mo., as is the case in other water-closets.
I do not claim, but on the contrary disclaim, the invention ot' a hopper having a removable plate for giving access to the bowl, as such a one is shown in the patent issued May 28, 187 3, to William S. Carr.
G is the valve-cylinder, mounted on the tray F. A stem, H, extends through the back head ofthe cylinder, and is pushed in by a lug on the lever when the lever is raised. At the other end ot the stem is a valve, 71 which is drawnagainst a seat in the end of the cylinder by a strong spring', t', spirally coiled about the stem between the front end or head and a cup-leather piston, lr, on the spindle.
If the valve is suddenly seated as the lever is dropped, the bowl would not iill with water; therefore the valve must be kept sus pended. To accomplish this I cast with the cylinder a supplementary cylinder, G', communicating with the body ot' the cylinder by a large port, Z, openin g into the cylinder G between the valve and piston. In the smaller cylinder is a valve, n, whose play is limited by a screw, 0, tapped into the valve-chamber, from which a small port, m, communicates with the large cylinder back of the piston. I is the union-coupling for the service-pipe, and J the coupling for the delivery-pipe, which opens into thevbody of the large cylinder.
' When the stem is pushed in to open the valve, the pressure ot' the water opens the valve n and tills the cylinder behind the cuppiston. When the lever is dropped the spring closes the valve l1r slowly, as the water behind the cup-piston must be forced through the small port m before the main valve h can be seated.
That I claim as my invention, and desire to secure by Letters Patent, is-
The valve-cylinder G, provided with the supplementary cylinder G', connected therewith by the ports l m, the valve a, and the adjusting-screw o, substantially as and for the purpose set forth.
GEORGE C. STONE.
