FLUSHING-VALVE FOR WATER-CLOSETS.

Specification of Letters Patent.

Patented Dec. 15, 1914.

Application filed December a, 1913. Serial macaw.

To all whom it may concern:

Beit known that I, Fnnncrs G. MERE- wn'rnnn, a citizen of the United States, residing at East Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Flushing-Valves for Water-Closets, of which the following is a specification.

My invention relates to flushing valves for water-closets.

In valves of this character difiiculty has been experienced in preventing leakin A valve consisting of a hollow rubber ba 1, cooperating with a valve seat on the flush pipe, has been found after use to become misshapen, and liable to non-registration in its seat when the latter has become rougher covered with a foreign substance, or when the surface of the rubber was somewhat rough, or the material somewhat non-yielding. Gravity valves of solid rubber have also been tried, as well as feather-edged valves consisting of a flexible annular flap, but neither of these have finished a continuously operative and successful seal or closure.

It is the essential object of my invention to overcome the above enumerated. defects, and to provide a flushing valve that will under no circumstances permit leaking; that shall be certain and simple in operation;

and that shall be inexpensive to' construct and maintain.

A further object is to insure the sealing material against waste and escape. v

To the above ends primarily my invention consists in such parts and in such combinations of parts as fall within the scope of the appended claims. I

In the accompanying drawings which form a part of this specification, Figure 1 is a side elevation of my flushing valve, showing the adjacent portions of the tank in vertical section, Fig. 2 a section on line a: w of Fig. 1 and, Fig. 3 a section of the valve and adjacent portion of the tank taken on a.

line corresponding with line y y in Fig. 2.

Like reference characters indicate like parts throughout the views.

In the drawings A represents the usual tank, in which is mounted the lower section B of the delivery pipe of which B is the upper section. It will be understood, however, that the sections B and B may if preferred constitute a single pipe. In the present instance the pipe section B is provided in its upper portion with an annular hollow extension b, in which is .mounted the vertical discharge pipe C. p In the present instance the lower end of the section B? has a threaded connection with the portion 72 of the lower pipe section as at b. Upon the exterior of the upper section, near the bottom thereof is a vertically disposed receptacle D, comprising an annular horizontal flange portion d, upon whose outer margin is a vertical flange or Wall d; the wall, flange, and adjacent portion of the section B constituting a receptacle. Upon the upper end of the last mentioned section is an annular flange d preferably downwardly inclined toward its margin. In the annular receptacle D, is a mass of quicksilver E'. A valve member F has a cylindrical body or side wall 7 and a top wall F,

the whole constituting a cylinder open at one end, like an inverted tumbler. This valve member is adapted to move or reciprocate vertically, and when in closed position it surrounds the major portion of the section B and has its lower extremity immersed in the quick silver resting upon the bottom portion 03 of the receptacle D, which portion all forms the valve seat. The flange 03 which is contiguous to or in contact with the inner face of the valve member F, incidentally serves to some extent as a guide to the vertical movement of the member F, but this flange is essentially purposed to prevent the escape of the quicksilver E over and through the top of the pipe section after the valve has been lifted and the water in the tank has begun to flow through the pipe sect1ons.

It is convenient but not essential that a special guiding means be employed for controlling the valve member F in its vertical travel. One convenient means for this purpose comprises two brackets Gone above the other, comprising loops 9 which embrace the pipe C, and loops 9 in the same plane and connected with the loops 9. The larger loops gr being connected by spaced vertical rods g Since the loops 9 are of slightly greater diameter than the diameter of the valve member F, the guide rods 9 serve to loosely confine the valve member in a vertical path. It will be understood that the described guiding means is not exclusive but that the valve may be guided in any usual well-known manner.

The valve may be raised or lowered with relation to its seat by any of the customary means. In the present instance the means employed comprises a two-arm lever H, having a horizontal portion 7:. and a vertical portion 72.; the latter being mounted on a pivot pin 2' in ears I upon the plate J fixed to the upper portion of the tank a.

A rod K with an operating handle lc is slidably mounted in the tank A with its end in contact with the depending portion h of the lever H, and operates in the usual well-known way to elevate the valve member F through a member L which connects the outer end of the portion h of the lever H with a ring Z attached to a stud Z, whose threaded shank Z engages the member F with the assistance of a nut Z. The member L in the present instance is a flexible member or chain, but may if preferred consist of a rod. The method of connecting the end of the member L with the valve member is not of essence to the invention, but when the latter member is composed of glass, as is preferred, the described means of connection is highly advantageous. Not only is the valve member F made of glass, but the pipe section B, and the receptacle D is in the present instance also of glass, since that material has been found to be more durable, not subject to corrosion, nor other influences which have heretofore interfered with the perfect operation of the valve and lessened the period of its use.

The described valve, valve seat or receptacle, and sealing agent, are so correlated that a perfect seal is assured, regardless of whether the valve approaches its seat uniformly at the same point or at varying points, and in any event the quick silver performs the sealing functions efficiently.

What I claim is,

1. In a flushing apparatus for water closets, the combination with the tank, of a delivery pipe mounted in the tank, a receptacle upon an intermediate portion of the pipe comprising a horizontal flange, and a vertical flange upon the last mentioned flange, a mass of quicksilver upon the horizontal flange intermediate the pipe and the vertical flange, a downwardly incllned guard flange upon the end of the pipe extending above the horizontal flange, and a hollow valve member surrounding the pipe and guard flange and seated in the mass of quicksilver.

2. In a flushing apparatus for water closets, the combination with the tank of a delivery pipe comprising two vertical sections, one of said sections being fixed in the tank, the second section being detachably engaged to the first section withinthe tank and composed of glass, an upwardly directed receptacle integral with the lower portion of the second section, a mass of quicksilver in the receptacle, a guard flange upon the upper open end of the second section, and a cup shaped valve member inclosing the second section and resting upon the receptacle within the quicksilver.

Y 3. In a flushing apparatus for water closets, the combination with the tank, of a delivery pipe mounted in the tank, a branch delivery pipe upon the first pipe and parallel therewith, a receptacle upon the delivery pipe, a mass of quicksilver in the receptacle, a guard flangeupon the delivery pipe .overhanging the receptacle, a vertical guideframe upon the branch pipe whose lower portion incloses the delivery pipe above the receptacle a cup shaped reciprocating valve in the frame movable into and away from the mass of quicksilver, a vibratory lever pivotally mounted on the tank above the valve member, a member connecting the lever and valve member, and means on the tank for vibrating the lever.

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

FRANCIS G. MEREWETHER.
