FLUSHING MECHANISM.

Specification of Letters Patent.

Patented Jan. 19, 1909.

Application led August 19, 1905. Serial No. 274,931.

To all whom 'it may concern:

Be it known that ALBERT SUocor, a citizen of the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Flushing Mechanisms, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in flushing mechanism for water closets, and the invention relates more particularly to that class of closets known as seat action closets, in which the flushing of the closet is produced by the raising and lowering of the seat of the closet.

The invention has for its object a novel form of flushing tank adapted to be used in connection with a bowl or hopper, the inlet and outlet of said tank being automatically controlled, by the raising and lowering of the seat of the closet.

Another object of this invention is to provide a novel form of flushing mechanism for closets which will be positive in its action, simple in its construction, and free from all danger of being injured by ordinary use.

lVith the above and other objects in view, which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts to be hereinafter more fully described.

The essential features of the present invention are necessarily susceptible to structural change without departing from the spirit and scope .of the invention, but the preferred embodiments of the invention are illustrated in the accompanying drawings, wherein Figure 1, is a side elevation of a ho per or bowl equipped with my improved ushing mechanism, FiO. 2, is a vertical sectional view of a portion of the mechanism, Fig. 3, is a rear elevation of a portion of the flushing mechanism as connected with the seat of a hopper or bowl, and Fig. 4, is a plan view of the hopper equipped with the actuating mechanism of the flushing tank.

In the drawing, 1 indicates a bowl of ordinary form, on which is hinged, as at 2, a seat 3, provided with a lid 4.

5 indicates the reservoir or tank, usually in the form of a large stand pipe as shown.

6 indicates an elbow connection secured in the water inlet of the bowl. Mounted upon the vertical leg or arm of this elbow connection 6 is a valve casing 9 in which is received the threaded lower end 8 of the stand pipe 5, said stand pipe being provided adjacent its lower end with a ilange T seated on the upper end of the valve casing 9. similar valve casing 19 is positioned upon the upper end of said reservoir 5 and is provided with a centrally aperturcd partition, having the valve seat 20 in the upper side thereof. The valve casing 9 is provided with a centrally apertured partition having the valve seat 10 in .its lower side.

A valve rod 14 is mounted in the stand pipe extends into the valve casing 19, through the valve casing 9, and through the ordinary arm or leg of the elbow 6, an aperture 13 being provided in said elbow for said valve rod, and suitable packing being placed in said aperture to prevent leakage of the water therethrough. The lower end of the rod carries a cup 14, which rests on a substantially elliptical shaped spring 16, carried by cross head 17 which connects the lower ends of two vertical rods 18a, attached at their upper ends to arms 1S which are carried by the seat 3, being rigidly connected at the rear end of said seat.

On the valve rod 14 below the partition in the valve casing 9 is a valve 15, adapted to seat, when the valve rod is elevated, with the valve seat 10, and upon the extreme upper end of said valve rod is a valve 23 adapted to normally seat with the valve seat 20 of the valve casing 19.

The seat 3 is adapted to remain normally in a slightly tilted position as seen in Fig. 1 of the drawings, and the valves 15 and 23 are shown in their normal position in Fig. 2 of the drawings, the valve 23 being seated, and the valve 15 unseated.

Vhen the seat 3 is depressed into engagement with the bowl, the outer ends of the arms 1S move upward, owing to the downward movement imparted to the forward part of the seat, the rods 1Saare elevated, and through the medium of cross head 1T and spring 16, valve rod 14 is elevated, forcing lvalve 15 against its seat, and unseating valve 28, whereby the water from pipe 21 may iiow in to ill the stand pipe 5. Vhen, however, pressure upon the seat 3 is relieved, valve rod 14 descends by gravity and also by reason of the water against valve 23 as well as against valve 15, and valve 23 is seated, while valve 15 is simultaneously unseated, thus allowing the water contained Within the stand pipe 5 to flow into the bowl and flush the same.

It will be noted that the stand pipe constituting the reservoir is, in my device, normally empty and, when the valve rod 14 is elevated as above described, should the pressure of water delivered into the stand pipe increase for any cause above the normal pressure, the valve rod by reason of its being yieldingly supported at its lower end by the spring 16, will yield under such excess pressure so as to unseat valve l5 sufficiently to permit the water to pass through to the bowl.

That l claim and desire to secure by Let ters Patent is In a flushing mechanism, the combination with a bowl, and a seat hinged thereto, of a pair of arms connected to the rear edge of the seat and projecting rearwardly, an elbow connected to said bowl, a valve-casing supported on said elbow, and provided with an apertured partition having a valve seat on its underneath face, a stand pipe supported on said valve casing and communicating therewith, a valve casing mounted on the upper end of said stand pipe having a central apertured partition provided with a valve seat on its upper face,a supply pipe communicating with said second named valve casing, a valve rod extending through said elbow and stand pipe, a valve on the upper end of said rod normally seated on the valve# seat in said upper valve casing, a second valve on said rod below the partition in said lower valve casing and normally unseatedr from the valve seat in said casing, vertical arms connected to the arms carried by said seat on the bowl, a cross head connecting said vertical arms, a spring on said cross head engaged by the lower end of said valve rod, said valve rod being capable of longitudinal actuation for reversing the said positions ofV the valves, and said valves adapted to automatically return to their normal positions upon the existence of an excess of any predetermined water pressure in said supply pipe.

In testimony whereof I affix my signature in the presence of two Witnesses.
