LOUIS M. HOOPER, OF RUTHERFORD, NEI/V JERSEY, ASSIGNOR TO THE J. L. MOTT IRON IORKS, NEW YORK.

OE NEW YORK, N. Y., A CORPORATION OF wATER-LoSET.

SPECIFICATION forming part of Letters,y Patent No. 763,561, dated June 1278 n `'Application filed March Z8, 1901iI `Serial No. 53,163. (No medal.) A

To all whom it may concern/.-

Be it known that I, Louis M. HoorER,a` citizen of the United States, and a resident of Rutherford, in the count;T of Bergen and State of New Jersey, have invented a new and Improved VVater-Oloset, of which the following is a full, clear, and eXact description.

My invention relates tov an improvement in water-closets and comprises novel features which will hereinafter b e particularly pointed out in the claims. i

Reference is to be had to the accompanying drawing, forming a part of this specification.

The drawing is a sectional elevation of a water-closet embodying' ,one method of constructing my invention. y

The form of construction shown in the iigure is given simply as an illustration of the preferred construction and not as representing the only construction which may be avail- I do not therefore wish to belimited to this construction alone.

My invention is particularly designed for use upon ships, yachts, and other vessels where the closets are located at some elevation above the water-line and in which the use of a pump for discharging the closets is not necessary. In such locations gravity is relied upon for discharging the closets; but closets located in this manner a short distance above the Waterline are subject to the action of the waves which dash against the sides of the vessel and which force water back through the dischargepipes and unless some means is provided for preventing such action it will often flood the closets. To prevent such action, I have introduced a check-valve between the basin and the outer end of the discharge-pipe which will turns upwardly into the discharge-passage D,

so as to act as ajet to facilitate the discharge of the bowl. The flushing-water is supplied to the closet through the pipe S. The passage D connects with a passage D', which eX- tends downwardly and which connects with a discharge or'soil pipe E.

Y A check-valve V is shown as located at the upper end of the passage D, said location being at the upper end of the siphon formed by the two passages D and D. The check-valve may be of any desired construction. The construction herein indicated consists of a plain leather or rubber disk B, which is provided with stiffening-washers and is hinged at its upper edge. This valve is also shown as being mounted upon a sleeve or thimble F, which is inserted within the upper end of the passage D.

It will be observed that the check-Valve is located as near as may be to the water of the I have discovered that if the valve be located at this point siphonic action is not interfered with, whereas if the Valve be located at a considerable distance from this point the siphonie action is delayed at starting, so that the water rises to an undesirable level in the bowl, and the breaking of the siphon is retarded', so that siphonic action continues and empties the bowl of water. Both these diiiiculties kare overcome by locating the valve at or about the position shown in the drawing.

I am aware that check-valves have heretofore been used in connection with siphonic water-closets, as shown and described in the patent to Bunting, No. 210,003, dated November 19, 1878; but such valves are located at a considerable distance from the crown of the siphon, and such constructions I disclaim.

The check-valve is made readily7 accessible by means of an opening left at the upper end of the passage D/ and which is covered by means of a plate I, which is secured by means of bolts or other devices, so that it may be readily removed.

By the term closet or water-closet as employed in the specification and claims I mean the structure which includes the hopper,

of a jet-aperture from which water is dis- I 5 charged into said Siphon in the direction of How therethrough, and a check-Valve located at the junction of the long and short legs of said siphon against which water impelled by said jet directly impinges.

In testimony whereoi I have signed my name to this specification in the presence of two subscribing witnesses.

L. M. HOOPER.
