SPECIFICATION forming part of Letters Patent No. 442,80 4, dated December 16, 1890.

Application filed April 12, 1889. Serial No. 306,924. (No model.)

To all whom, it may concern.-

Be it known that I, CHARLES G1ELoW",.a citizen of the United States, residingin Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Flushing-Tanks for ater-Closets, of which the following is a specification.

My invention relates to overhead cisterns or tanks used for flushing water-closets.

The object of my invention is to provide means for preventing the somewhat disagreeable and objectionable gurgling noise which attends the use of these overhead tanks, especially at the last end of the water-discharge.

My invention consists in the means I employ to accomplish this result-that is to say, in providing the tank ortheflushingor measuring compartment thereof, if it is divided, as usual, into two compartments, with a cover having a limited opening for the admission of air, whereby the violence of the final discharging of the water and the noise occasioned thereby may be prevented.

It also consists inthe novel devices and novel combinations of parts and devices herein shown and described, and more particularly pointed out in the claims.

In the accompanying drawings, which form a part of this specification, Figure 1 is aplan view of a device embodying my invention, and Fig. 2 is a section on line 2 2 of Fig. 1.

In said drawings, Arepresents the tank or cistern; B, the measuring of flushing compartment thereof; C, the water-inlet or supply pipe furnished with a float-valve Cof any ordinary or usual construction; D, the discharge or flushing pipe leading to the water-closet bowl, for example; D, the discharge-valve, and D the lever for operating it. The fiushiug-valveD maybe of any ordinary orknown construction; but I have shown in the drawings and prefer to employ the now well-known siphon-plunger form of valve, so that the valve requires to be only momentarily open ed to start the siphon.

The partition to, between the compartments A and B, is furnished with a small opening or passage a, so that after the compartment B is emptied it may refill from the cistern A.

The compartment or flushing-tank proper B is closed at the top by a cover B, preferably of sheet metal, having an opening b for the siphon-plunger D to project through, and in which the plunger fits somewhat loosely, so as to leave a limited passage around the plunger for the admission of air to the closed tank B when the valve D is raised or open. As the opening a between the cistern A and the tank B is also of limited area, the violence of the discharge of water through the flushing-pipe D will be controlled by the comparatively small openings through which air or water may enter the closed tank B to replace the water flowing out through the flushingpipe D. By thus simply providing the overhead cistern or the discharging-compartment thereof, if it is divided into two compartments, with a closed cover having a passage of limited size for the admission of air, I prevent the disagreeable noise heretofore incident to the use of these overhead flushing-tanks.

The opening I) in the cover 13 is surrrounded with a collar 1) to re-enforce the tin or sheet metal of which the cover B is composed. The

' collar or ring I), being secured by screws to the cover B, also serves as a guide for the plunger D. The air-inlet around the plunger D and the water-inlet a are of small area as compared with the discharge-pipe D.

The opening I) in the cover Bis made large enough to permit the removal and insertion of the si phon-plunger, the collar 1) serving to somewhat contract the opening and being removably secured to the arms B by the screws b The water in the compartment B is discharged more rapidly than it enters through the opening, a, and the water in the main tank A being above this opening a no air I enters therefrom, and the limited air-supply at Z) is not sufficient to interfere with the comparative noiseless service of the water through the opening d in the siphon-plunger; but the air is fed through this opening I) at the finishing of the discharge gradually or in limited quantity to break the siphon slowly.

I claim- '1. The combination of a cistern or tank A, having a closed compartment B, its discharge- 3. The combination of a cistern or tank A, having closed compartment B, water-inlet a, discharge-pipe D, valve D, and an air-inlet to said closed compartment of small size compared with the discharge-pipe, said air-inlet being open during the discharge of Water from said compartment B, substantially as specified.

CHARLES GIELOW.
