FLUSHING APPARATUS.

8,683. Specification of Letters Patent. I PatentedNOV. 2, 1909.

Application filed. August 3, 1906. Serial No. 329,056.

all whom it may concern: ably larger than the valve-seat for ready ad- Be it known that I, PAUL S. MILLIGE, a mission of the -valve and for permitting izen of the United States, residing at proper grinding of the valve-seat through amilton, in the county of Butler and State the bushing opening. The valve preferably 50 Ohio, have invented certain new and usehas wings 18 depending therefrom and l Improvements in Flushing Apparatus, guided by the walls of the passage 9. An which the following is a specification. 1 operating lever 19 is pivoted to the valve My invention relates primarily to flushing stem 13 at 20 and to a link 21 at 22, the paratus for closets, and the invention will link in turn being pivoted to a lug 23 on the 5 readily understood from the following casing.

Fig. 2 is a front elevation of my with the connection 2, a sub-passage 28 proved device. Fig. 3 is a rear elevation being projected into the direction of the the same. Fig. lis a central vertical secpassage 27 and into the direction of the n of the same on the line 0000 of Fig. 3. passage of water through the passage 27.

g. 5 is a vertical cross-section of the same Preferably at the opening '26 there is a ken on a line correspondingto the line chamber 29 in the passage 27. A wall 30 y of Fig. 4; and, Fig. 6 is a vertical separates the passage 27 and the compartoss-section of the same taken on a line corments 7 and 8. A valveseat 31 is located sponding to the line 2-2 of Fig. 4c. in this wall, and a valve-seat 32 is located in 1 represents the casing which may have the wall 33 between the chamber 25 and the itable connection 2 with a bowl 3 or other chamber 29. 'A valve 34; has seating faces ntainer which it is desired to flush. The 35 36 adapted to seat against the valve sing may be connected with any suitable seats 31 32 respectively, forming a comter or fluid supply as through a pipe 4: pound valve. The valve also has a stem 37 d a union-coupling 5 connecting with a preferably having sliding fit in an opening pc 6 threaded into the casing. 38 adjacent the valve-seat 31. The valve The casing comprises a plurality of comalso has an annular flange 39 forming a rtments, one of which is adapted to re hub having sliding fit in a bearing 40 shown I ive the water or other fluid, and in which as an annular wall projected from the Wall e latter acts for automatically closing a 30. The seating-face 35 is shown larger pply valve. The other compartment than the seating face 34, the opening 26 ves as a relief compartment when the being of substantially less diameter-than the shing is initiated. Thus 7 is. a pressure diameter of the inner end of the valve at mpartment and Sis a relief compartment, the annular flange or hub 39. The outer e latter being preferably located below the wall 41 of the casing has an opening l2 into essure compartment. There is a passage which a plug 43 is threaded, the plug havbetween the compartments arranged to be ing a stem 44 projecting inwardly toward sed by a valve 10 adapted to seat on a the valve 34. This stem forms a limiting lve-seat 11 shown as located on a shelf 12, member for the unseating travel of the come shelf forming the separating wall bepound valve, the compound valve having a een the compartments. The opening of travel corresponding to the space 45 between e valve 10 initiates the flushing. I have it and the end of the stem. The opening 42 own it manually operated, although it is is preferably larger than the bearing-face vious that automatic means may be pro for the compound valve and the valve-seats ded for the purpose, as by suitable confor permitting fitting of the latter. ction with the closet seat. The valve is An opening 46 connects the chamber 25 own as formed with a cone-seat. It has with the pressure compartment 7, forming stem 13 extending therefrom taking a sub-passage into said compartment, and I rough a bushing 14 threaded to the casing, prefer to provide a regulating valve for this itable packing 15 being in the bushing opening. I have shown such regulating 11O ich is compressible by a gland 16 through valve at 4-7 on a stem 48 threaded at 49 into bearing nut 17 This bushing is preferthe wall of the casing and having an adjusting knob 50. The stem 13 is preferably provided with a slot 51 through which the stem of the regulating valve 47 and stem 44 may project. A spring 52 takes about the stem 13 and is seated between the shoulder 53 on the stem and the bushing 14. The opening 46 is substantially smaller than the opening 26, so as to receive substantially less fluid than the'latter. The opening 46, it will be noted, is shown in the wall of the pressure-compartment 7, outside the longitudinal plane of the valve-seat 31, and forms a by-pass from the fluid passage to the pressure-compartment around said valve, for conducting the fluid from the front to the rear of the valve 34 without passing through said valve, thereby permitting said valve to be made solid, and forming a cheap construction.

In operation when the flushing operation is closed, the water from the head of pressure is checked by the valve 34 at the valve-seat 32 and by the valve 10, the pressure compartment being filled with water. When it is desired to flush, the valve 10 is unseated, which permits the water in the pressure compartment to pass into the relief compartment 8. As soon as pressure in the pressure compartment is relieved, the compound valve will be unseated by the pressure of the supply, the unseating being limited by the stem 44. This unseating of the valve 34 will permit the water to pass through the opening 26 and the passage 27 past the sub-passage into the bowl, thereby flushing the latter, the direction of the sub-passage 28 insuring that the flow of water under pressure through the passage 27 shall not prevent the passage of water through the sub-passage 28. The office of the relief compartment is to receive the water from the pressure compartment when the flushing is initiated and obviate the liability of the water which passes through the flushing passage, checking the flow from the pressure compartment. The valve 10 is then reseated. The water will pass through the passage 27 and will also pass through the opening 46 into the pressure compartment. The sub-passage into the pressure compartment however is comparatively slight in cross-section and may be regulated by the regulating valve 47, depending on the pressure of the head of water and the length of time it is desired to have the flushing continue. The greater the pressure and the greater the length of time of flushing, the smaller will the opening 46 be regulated. The water passing through the opening 46 into the pressure compartment will gradually refill that compartment, and the pressure exerted by the water passing through said opening will gradually reseat the valve 34, and the more nearly sald valve is reseated the greater will be the pressure exerted in the pressure com artment through the opening 46. The di erential pressure pressure compartment also causes the valve 10 to be firmly seated, as the pressure at the outer end of said valve, when said valve is seated and the apparatus closed, is substantially only atmospheric pressure. The bore of the feed-pipe is also greater than the o enin 26 forcausin aback )ressure which compels water to pass through the opening 46 at all times when said valve 34 is open.
