FLUSHING DEVICE FOR WATER-CLOSETS, 800.

SPECIFICATION forming part of Letters Patent No. 434,020, dated August 12, 1890.

Application filed January 28, 1889. Serial No. 297,867- (No model.)

To all whom it may concern:

Be it known that I, WILLARD C. HUGHES, a citizen of the United States of America, and a resident of the city of Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Flushing Devices for ater-Closets, &c.; and I do hereby declare that the following is a full, clear, and exact description of the in- Vention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form part of this specification.

My invention relates to an improvement in flushing devices for water-closets.

It is the object of my invention to provide a flushing device that is simple in construction, prompt in its action, and one that will overcome the disagreeable gurgling, choking, sucking noise that is usual in such devices as ordinarily constructed and used.

In the drawings which accompany and form a part of this specification, Figure 1 shows a side elevation of my device mounted upon the bottom of the tank or cistern, a section of which bottom is shown. The dotted lines indicate various positions of movable parts.

Fig. 2 shows a substantially vertical central longitudinal section of the device, as shown in Fig. 1, some parts being omitted. Fig. 3 shows a section of the device, taken on line A B of Fig. 2. Fig. 4 shows a section of the device, takcn on line C D of Fig. 2.

Similar numerals of reference refer to similar or like parts in the several figures of the drawings.

Referring to the drawings, 1 shows a section of the bottom of the tank or cistern, within which the device is placed and which contains the water used by the device.

2 is the flushing or discharge pipe. The upper end of pipe 2 passes into the double elbow or turn 4, where it is secured, as I prefer to secure it, by the clamping action of screw 3, Figs. 1, 2, and 3, the elbow being slit alittle and provided with ears for the screw 3. The double elbow 4 is connected with cylinder'5 at or near the top thereof, and so as to receive a flow of water from the cylinder 5 and carry it over in pipe 2. Cylinder 5 is provided with one head 6, and the lower end open.

7 is a piston fitting and working in cylin 5 5 der 5.

8 is a piston-rod for actuating the piston, passing air tight through cover 6, and is provided'with a shoulder 9 for limiting the downward movement of the piston. It is also pref- 6c erable to provide an elastic cushion 10 between the shoulder 9 and the head 6, and which may also act as a packing. Piston 7 may or may not be provided with small openings 11, which may or may not be provided with upwardly-opening valves.

To the upper end of piston-rod 8 may be connected a lever 12 for operating the same.

A flap-valve 11, intended to close the lower end of the cylinder 5, is provided, pivoted at 15. To thefiap-valve 14 is secured arm 16, which arm carries float 17.

A cushioning chamber 18 is provided, having a plunger 19 working therein, which plunger has connectingrod 20 attached thereto. Connecting-rod 20 is provided near its lower end with a slot 21 and is engaged, within the slot by a projection 21 upon flapvalve 14. Plunger 19 is provided with an opening through the same closed by an upwardly-opening valve 22. Cushioning-chamber 18 is provided with an opening 23 at or near its upper end, which opening is con trolled by screw 24. A hook 25, mounted upon a spring, which always holds it in placewhen not forcibly displaced, projects a little over the lower end of the cushioning-chamber l8 and limits the downward movement of the plunger 19. The piston 7, when in its lowest position, stands directly opposite recess 26, 0 Figs. 2 and 4,'which is practically an enlargement of the cylinder at this point. The piston is held in its central and stable position when opposite the recess 26 by guides 27 27 p 27 27, Fig. 4, and in such position that it will 5 readily ascend in the cylinder. The object of the recess 26 is to provide an opening for the passage of water into or out of the cylinder 5 without disturbing the piston when in its lowest position.

An air or vent pipe 28 is provided extending from the exterior down the interior of pipe 2 a certain distance, and assists in breaking the siphon action. Pipe 28 is not essential, but desirable, also, the same with chamber 18 and working parts.

It is not desirable that the level of water in the tank should be above point 29; but should the tank be filled above that point the surplus water will pass over the point 29 into pipe 2, and it will then act as an overflow. The cylinder 5, the turn 4, and pipe 2, when in action, form a siphon.

Theoperation of the device is substantially as follows: The tank being full nearly up to point 29, which also fills the cylinder 5 withi water, and it being desired to flush the basin, the piston 7 is drawn up by means of lever 12 and connecting parts. This movement throws the water contained within the cylinder over the turn or double elbow 4 and down pipe 2, and starts a siphon action of the parts. This siphon action continues, the momentum of the water holding the piston 7 up to head 6, or nearly so,until the water in the tank is reduced to the level indicated by line 0, Fig. -1., and the float 17 has descend-ed to upper position indicated by dotted lines. By this movement the flap-valve 14 is brought near enough to the open end of the cylinder to be caught by the suction of the current of water, and would be brought up to and close the end of the cylinder instantly but for the resisting action of the cushioning-chamber 1S and workingand connecting parts. As the float 17 descends with the lowering water in the tank, the flap-valve 141s brought nearer to the open end of cylinder 5 without resistance, while the projection 21 is moving along and toward the upper end of slot 20 in connecting-rod 20. When the projection has reached the upper end of the slot 20, it then meets the resisting force of the cushioning-chainber. The resistance is caused by the necessity of expelling the water from chamber 18 before flap-valve 14 can entirely close the open end of cylinder 5, and the speed with which this is done depends on the size of opening 23, which is controlled by screw 24. When flap-valve 14 has closed the end of cylinder 5, the flow of water is stopped, air enters through the vent-pipe 28 or lower end of pipe 2, breaking the siphon action, and the piston '7 descends by its own gravity to its lowest position. The flap-valve 14 is returned to the position shown in full lines, equilibrium is established in chamber 18 as the plunger 'descends by water passing in through valve 22 or opening 23, or both, and when the tank is filled the device is ready for a repetition of the processes described.

Various modifications and alterations may be made in and from the constructions described and various parts omitted without departing from the spirit of my invention.

That I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a flushing device, of the tank, a flushing-tube, a double elbow con- 2 necting therewith, a cylinder having one head connecting with the double elbow at the side near the head, the plunger working in the cylinder, and the outwardly-opening valve for closing the open end of the cylinder rigidly connected with the float, both being pivoted to a lug on the cylinder, so that the face of the valve will swing into line with the open end of the cylinder and close the same, sub; stantially as set forth.

2. The combination of a cylinder having a closed top connecting at its side, at or near its top, with the short arm of a siphon, a piston working in the cylinder, an outwardlyopening Valve for closing the open end of "the cylinder, and the float connectin g with valve.

3. The combination of the siphon, an outwardly-opening valve for closing the short arm thereof, the float connected with the Valve and the cushioning-chamber, and plunger connected with the valve.

4. The combination of a flushing-pipe, the double elbow, the cylinder open at its bottom and connected at its top with the double elbow, the piston working in the cylinder, and the outwardly-opening valve for closing the open end of the cylinder.

5. The combination of a flushing pipe, double-elbow cylinder connecting with the elbow, the piston working in the cylinder, the flap-valve, the float connected with the valve, the cushionin g-chamber, and plunger connectin g with the valve.

6. The combination of a siphon, a piston working in the short arm thereof, the short arm having an internal groove or recess opposite the piston-head at its downward limit of movement, the outwardly-opening valve for closing the short arm of the siphon, and the float for operating the valve.

In witness whereof I have affixed my signature in presence of two witnesses.
