ALEXANDER FICKAY, OF DETROIT, MICHIGAN.
FLUSHlNG-VALVE FOR WATER-CLOSETS.
SPECIFICATION forming part of Letters Patent No. 414,158, dated October 29, 1889. Application filed May 18, 1889. Serial No. 311,321. (No model.)
To all whom, it may concern:
Be it known that I, ALEXANDER McKAY, a citizen of the United States, residing at Detroit, inthe county of Vayne and State of Michigan, have invented certain new and useful Improvements in Flushing-Valves for Tater-Closets; and I do declare the following to be a full, clear, and exact description of the invention, such as 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 letters and figu res of reference marked thereon, which form a part of this specification.
This invention relates to flushing-valves for water-closets and to that class of closets in which such valves are operated by a floatlever.
The invention consists in the combination of parts, as hereinafter set forth, and particularly defined in the claims.
In my invention the valve-stem is provided with an aperture or opening through its vertical portion, which communicates with an opening formed in its horizontal portion at the top. The lower end of the stem carries a plunger or piston-head, which works in a cup or cylinder supported in the valve-chamber by bridges, whereby, when the valve is depressed to admit a flow of water, the piston-head is forced into the cup or cylinder, displacing the air therein through the apertures in the stem,
and as the valve is closed by the reaction of the spring the plunger or piston-head in rising forms a vacuum in said cup or cylinder, which creates a suction through the apertures in the valvestem, causing air to fiow through into the cylinder from the cistern and thus retard the sudden return of the valve, but allowing it to gradually close with but little, if any, noise, as will be hereinafter more fully set forth, and the essential features of my device pointed out particularly in the claims.
In the accompanying drawings, forming a part of the specification, Figure 1 is a sectional elevation of a closet, showing my improved flushing-valve in connection and relation thereto. Fig. 2 is a front elevation of Fig. 1, partly broken away and in section on dotted line a; Fig. is a central vertical section of Fig. 1, taken on dotted line 3 11 Fig. is a central vertical section of the valvestem and coiled spring in normal position. Fig. 5 is a central vertical section of Fig. 3, taken at right angles, showing valve-stem and spring depressed. Fig. 6 is a plan in detail, which will be referred to.
In the letters of reference in the drawings, A represents the bowl, T the cistern or tank, D the discharge-pipe, S the seat-board, and P the operating-rod to the discharge-valve, all of which are common in Water-closets of this class, and will therefore need no special mention.
1) represents the flushing-valve containing my invention, the case to which consists of the two parts C E, the upper portion of the part E being screw-threaded at a to receive the lower screw-threaded portion a of the part C, on which part is also located a screwthreaded collar 0, as clearly shown in Fig. 3.
cl indicates the induct-port.
Suspended centrally within the chamber of the portion E of the case by means of the bridges r is a cup or cylinder Z,in which the plunger or piston-head l-I, attached to the lower end of the valvestem 1, works in operating the valve. Said piston-head is provided with a leather or flexible covering, as 6, (shown in Fig. 4,) to form an air-tight packing in the cup or cylinder, and is held in position on the piston-head by the washer 0.
Y shows a yoke or collar, which is supported on the upper edge of the cup or cylinder Z, and forms a support for the lower end of the coiled spring 3, and through said yoke and coiled spring the valve-stem passes, rising and falling as the valve closes and opens. The upper end of the spring 8 rests against the under face of the collar 10, which collar and the shoulder '7' of the valve-stem serve to secure the valve f in position upon the valvestem t. Passing vertically through said stem is an aperture 1', which communicateswith a right-angle aperture 7;, formed in the stem at the upper end, all of which are clearly shown in Figs. 3 and a. The valve when in its normal position is held closed against the valveseat Z by pressure of the coiled spring 8, as shown in Fig. 3.
The part 0 of the valve-case is provided
