IMPROVEMENT IN TANKS FOR WATER-CLOSETS.

Specification fox-iningpari o1 Litters Patent No. 149,746, dated April 14,1874; application filed March 11, 1874. I

To all whom it may concern Be it known that I, JAMES GRIFFITHS, of Deptford, in the county, of Kent, 'England, have invented a certain new and useful Improvement in Water-Tanks, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which my invention appertains to make and use the same, reference beinghad to the accompanying drawing, forming a part of this specification, in which-.-

Figure 1 is an elevation of my improved tank with the side broken out to showthe arrangement of the compartments and valves. My invent-ion relates more especially to that class of water-tanks which are used for supplying water-closets and sinks; and consists in a novel construction and arrangement of the parts, as hereinafter more fully set forth and claimed, by which a more effective and economical apparatus is produced than is now in common use.

The extreme simplicity of my invention renders an elaborate description unnecessary.

In the drawing, A is the main tank, which is divided transversely by the walhlt to form the small tank B, having the sub-tank 0 formed by the false bottom S. WVithin the main tank A there is also a compartment, T, opening into the tank B by means of the aperture 0. The tank A is provided with an ordinary cap-valve mechanism, G M, opening into the chamber T, and connected by the chain 1? with one end of the valve-lever H.

The chamber B is also provided with a capvalve mechanism, F L a, but of greater capacity, opening into the chamber 0, and connected by the chain N with the opposite end of the lever H. A The tube D is for supplying From the foregoing the nature and operation of 'my invention will be readily understood by all conversant with such matters.

In tanks of the ordinary construction, a

great waste of water frequently occurs by accidentally or purposely leaving the pull on or the valve open.

There is also no' provision for flooding or washing the basin of the closet after the pull is released, difficulties which are entirely obviated by my invention.

The lever H is provided with a weighted or gravitating end, at, which causes that end of the lever to fall when the wire J is released, thus closing the valve F L a, and opening the valve G M b. The last-named valve be ing open, water from the tank A will pass into the compartment T, and thence through the aperture 0, and fill the tank B. If, now, the wire J is pulled downwardly, the valve G M b will be closed, shutting off the water from the compartment T and tank B, opening the valve F L a, and filling the chamber or subtank C.

It will be seen that, when the wire J is pulled and the valve F L a opened, the water filling the tank 0 will be discharged through the pipe E, air passing into the tank through the tube D to supply the vacuum thus caused. The valve F L a is of greater capacity than the discharge-pipe E, so that when the valve is open water will be passed from the tank B to the sub-tank G faster than it is discharged from the subtank by the pipe E. Thus, when the valve F L a is closed, by releasing the pull attached to the wire J the water in the tank 0 will be entirely discharged to wash the basin after water has ceased to pass from the tank 13 into the tank 0.

It is important, usually, that water should be supplied to water-closets and sinks very rapidly, and in quite large quantities. It is also equally important that it should not be wasted. For these reasons, I provide the tank B with the sub-tank O,having the large airpipe D. When the wire J is pulled, the contents of the sub-tank C will be very rapidly discharged; but, if the wire is not released, or the pull is accidentally left on, the valve Gr M I) being closed, no more water can be wasted than what is in the tanks B C at the time, as will be readily obvious, thus preserving the contents of the main tank A.

Hence it will be seen that by my improvement the proper quantity of water is measured out from the tank B, thus preventing all waste,

and at the same time furnishing a means of compartments T B C,Va1ve G M Z), lever B, rapidly supplying water to the sink or closet, pipe D, and valve F L a, combined to operate as desired, and also of washing the basin of substantially as and for the purpose set forth the closet by a discharge of water after the and specified.

pull is released. JAMES GRIFFITHS Having thus described my invention, what itnesses:
