FLUSHING APPARATUS Filed Nov. 8, 1927 v INVEPITOR 4 WWW.
V. WWW-r0,
ATTORNEYS.
Patented Apr. 8, 1930 UNITED STATES FREDERICK OPPERMAN, 0F GREENWICH, CONNECTICUT FLUSHING APPARATUS Application filed November This invention relates to an improvement in flushing apparatus such as employed in flush tanks, for example, and has for one of its objects, the provision of an improved valve mechanism therefor, this valve mechanism being so constructed and arranged that the same will remain in serviceable condition for a very much longer period than valve mechanisms now in use for the same purpose, and in which a valve of rubber is usually employed.
A further object of this invention is the provision of flushing apparatus employing a flush valve in which a new and novel seat or seating arrangement is provided for the valve, this seat being of such a nature that the valve will always seat fluid tight.
A still further object of my invention is the provision of flushing apparatus employing a hollow valve of improved construction and seating in or on a new novel seat, guiding means being provided for the valve, to insure that the valve will be guided properly towards its seat in the flushing operation.
As mentioned above, it is customary or usual in this type of apparatus under present practice, to employ a hollow rubber valve, which soon becomes worn and will not seat properly, thereby allowing a constant escape of water from the tank. The action of the water in the tank upon such valve also causes the valves to deteriorate and become leaky thereby rendering them unfit for satisfactory use.
In the present construction I provide a metal valve of novel construction cooperating with an improved seat, means being provided whereby should the valve, which is of hollow construction, become leaky from any cause, the water entering the same will flow therefrom by gravity and hence not interfere with proper functioning of the valve.
In the drawings accompanying this application I have shown one embodiment of my invention- 8, 1927. Serial No. 231,819.
Fig. 1 illustrating the same in sectional elc= vation, while Fig. 2'is a section taken on the line 22 of Fig. '1.
Inasmuch as my improved apparatus is capable of use with flushing apparatus constru'cted'in the usualway so far as tank and operating mechanisms are concerned, .I have not deemed it necessary to show these parts as they are well known in this art.
The drawings show at 1, a pipe through which the water from the flush tank is to escape, the upper end of this pipe 1 being flared as indica-teclat 2, to provide an inclined or pitched or tapered valve seat, circular, when viewed inplan. The'pipe 1 is-providedwith two spiders 3 and l extending transversely thereof and each provided centrally with an aperture "5. The spiders 3 and .4: are guiding spiders provided for the purpose of assisting. in the guiding of'my improved flushvalve 6 to its seat. The number of guiding devices employed may vary, two having been shown merely for purposesof clarity of description.
The flush valve 6 is of metal, for example,-
aluminum, and is of hollow construction as illustrated, the lower portion of the sides thereof being tapered or inclined as indicated at 7'to provide a frustdconical formation, the base of the cone facing away from the seat '2. The bottom of the valve designated 8 is planar but may take other forms if desired. The inclination of the sides of the valve body is different from that of the valveseat-and Where the bottom 8 meets the i apex of the fru-sto cone 7 provides an edge 9 which seats on the valve seat 2. In other words, the seat 2 is tangential to the valve sides to provide a line-contact; I have found by actual use of a valve constructed'in acunderstood that the bottom 8 and the top 10 of the valve may be integral with the side walls thereof just as illustrated.
As above mentioned, means are employed for guiding the valve 6 to its seat 2, and this means is provided by attaching a pipe 12 to the bottom 8 of the valve, this pipe being screwed into the bottom or attached to the same in any other convenient fashion, the pipe, however, in all instances, preferably communicating with the interior of the valve so that should the valve leak from any cause, water entering the same will be free to escape therefrom through the guiding pipe 12. The pipe 12 passes downwardly through the orifices 5 of the guiding spiders 3 and 4 and to prevent the valve being lifted beyond the limits of the guiding pipe 12, the lower end of the same is provided with a cotter pin 13 of such dimensions that the same will not pass through the orifice 5 in the lower guiding spider 4. It is obvious that various modifications may be made in the construction above described within the purview of this invention.
lVhat I claim is:
1. In flushing apparatus, the combination of a frusto-conical hollow metallic valve, a frusto-conical seat therefor, the bases of said frusto cones facing the same direction but making different angles with the horizontal and a guide tube for the valve opening into said valve.
2. In flushing apparatus, the combination of a hollow metallic float valve, a seat therefor, the periphery of said valve adjacent the seat being tapered, said seat being pitched at a different angle from the taper of the valve so that a line contact is produced between the valve and seat below the top of the seat.
3. In flushing apparatus, the combination of a hollow metallic valve having tapered sides, a tapered seat therefor tapered at a greater angle than the valve sides, and a guide tube communicating with the interior of said valve and attached to the bottom of said valve.
4. In flushing apparatus, the combination of a pipe, one end of which is shaped to provide a tapered valve seat, a hollow valve having tapered sides cooperating with said seat, said seat being tapered at a greater angle than the taper of the valve body, a tube attached to the bottom of said valve and communicating with the interior thereof, and guides for said tube extending transversely of said pipe.
5. In flushing apparatus, the combination of a metallic valve having a frusto-conical formation, a tapered seat therefor, the seat being tapered at a greater angle than the valve so as to provide a line contact between the valve and seat below the top of the seat.
6. In flushing apparatus, the combination of an inclined valve seat, a hollow metallic
