Specification of Letters Patent. v Patented Sept. 18, 1917.

Application filed July 10, 1914. Serial No. 850,080.

To all whom "it may concern:

-Be it known that 1, WILLIAM U. GRIF- r1rns, a citizenof the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new*and useful Improvements in Flushing Apparatus for ater- Closets, of which the following is a specification.

My invention relates to improvements in flushing apparatus for water closets and it has for one of its objects to provide an improved construction of means whereby when the valve for closing the port of the tank leading to the closet bowl is operated the valve for controlling the water supply is simultaneously opened.

A further object is to provide means for automatically cutting 0d the flow of water into the tank whenthe'water has reached a certain predetermined height therein.

Other objects .and advantages of my in-.

vention will be referred to in the detailed description thereof which follows or will be apparent therefrom. i

In order that my invention may be more readily and easily understood reference should be had to the accompanying draw ings forming a part of this specification and inwhich,""fl p Figure 1 is a front elevation of awater closet apparatus embodying my invention, the flush tank being shown,howev'er, in vertical section; V Fig. 2 is a side elevation of the same;

Fig. 3 is a longitudinal. vertical section on the line 3 -33 of Fig. 1;

F ig. 4 is a transverse vertical section. at right angles to the section shown in Fig. 3 and showing a detail of construction;

Fig. 5 is aview similar to that shown in Fig. 1 of the drawings but in which the construction is modified by the omission of the means for automatically cutting off the flow of water from the supply pipe into the flush tank; and

Fig. '6 is a longitudinal sectional view of the supply pipe and the valve mechanism associated therewith for controlling the flow of water therethrough into the flush tank such viewv beingtaken in aplane parallel to tlieview shown in Fig. 5.

' Before proceeding with a detailed description oft-he apparatus it maybe noted that the constructions illustrated in Figs. 1 to 6 inclusive are adapted for use in connection with water closets situated out of doors where the water if allowed to remain in the pipes would be frozen in cold winter weather. These constructions provide means whereby the water is allowed to drain out of those portions of the pipes which are situated above the freezing line of the earth.

Referring now to the drawings, 1 designates a closet bowl, 2 a closet seat having a rearwardly extending arm 3 of'any suitable known construction, and 4 a flush pipe leading from the flush tank to the bowl in the Y usual maimer. The flush tank is designated by the reference numeral 5. r

' The rearwardly extending arm 3 is adapted to contact with the lower end of the rod 6, which may be weighted as indicated at 7. This rod extends into the flush tank 5 and has connected therewith, by a pivot 10, a valve 11 which valve is adapted to open and close theport 12 communicating with the flush pipe 4-. hen the seat 2 is depressed the arm 3 is raised to contact with the lower end of the rod S to-lift the same to cause the valve 11 to close the port 12. When, however, the arm '3 returns to itslowermost position as indicated in Fig. 2 the rod 6 drops underneath a lever 16 provided at its outer free end with a weight 17. Any other suitable means than the rod 6 may be employed intermediate the arm 3 and the valve 11 whereby movement of said arm may effect the closing and opening of the valve.

In the form of construction shown in Figs. 1 to t inclusive the end of the lever 16 opposite the weight 17 is connected at 18 to the upper end of a link '19 having pivotal connection at 20 to a projection extending outwardly from the part 21 'which projects upwardly from the bottom of the flush tank 5 in alinement with and in continuation of the water supply pipe 22. The lever 16 is connected intermediate its ends at 23 to the upper end 2% of a rod 25 which extends downwardly in the water supply pipe 22 to a point below the frost line. The lower end of said rod is provided with a valve 26 the bottom of which is adapted to contact with the seat 27 formed in the said 'supply'pipe to close the same to prevent the bewithdrawn upwardly through the supply pipe 22 and the continuation thereof 21.

3 0 designates packing .material held in place by means of a gland 31 to prevent escape of water through the opening in 21' around. the portion '24 of the rod 25.

33 designates a projection extending laterally from the part 21 and having a passage-way 34 therein'in communication with the supply. pipe 22. The outer portion of the lateral projection 33 is provided with an upwardly extending portion 35v which is hollow and provided with a spout 36 through which the wateris discharged into the flushtank 5. The opening from the passage-way 34 in the part 33 to the spout 36 is adapted to be closed. by means of a cylindrical valve 37 which may beseated upon and-lifted from the seat 38 by the pressure of the water against the lower or inner end thereof. The valve 37 is protion 43 at right angles to the slot 42 therein vided at its upper end with a flange 39 against which any water which might pass upwardly around the valve would strike and thereby be prevented from prOJecting upwardlyover the top of the flush tank.

The upwardly projecting portion 35 is provided upon opposite sides with projections 40 in which apivot 41Iis supported which pivot extends'through a slot 42 in the portion 43 extending upwardly from the valve 37. The double cam member 45 is supported uponthepivot 41 and is situated in a slot 46 extending through the por- 48 designates an arm having connection with the double acting cam 45 and the outer end of which is providedwith a float 49.

In operation it will be understood that i when the rod 6 is raised the finger 15 thereon (shown in Fig. 1 in dotted lines) lifts the lever 16 to'lift the rod 25 and open the valve 26to permit water to flow upwardly through the said valve and through the supply pipe 22 into the passage-way 34 in the part 33 and out through the spout36 into the flush tank 5. The water continues to flow into the flush tank until the float 49 is raised to a height'suflicient .to cause the lower part 50 of the cam 45 to contact with the upper end of the valve 37 as illustrated in Figs. 1, 3 and 4 of the drawings to force the said valve 37 downwardly to close the opening fromthe passage-way 34. so that the flow of water into the flush tank is thereby out 01f. If by any chance the means for, effecting the cut-ofl or for closingthe valve 37 should not work and water in excess should flow into the tank 5 no harm would result beca'usesuchiexcess would flow .out through the over-flow pipe 51. When the rod 6 is permitted to drop the weighted lever 16 also drops toeflect closing of the ter may .be in the space surrounding the valve 37 to flow into the passage-way 34 and thence. into the supplypipe '22, downwardly therein and out through the waste pipe 39 intothe soil pipe 30.

Referring now to: Figs. 5 and 6 of the drawings, it may be noted that the construction in general is similar tothat'shown in Figs. 1 to 4 inclusive except for the omission of the means acting automatically to out off the flow of water into the flush tank. In said Figs. .5, and 6 the lever 16 is pivotally connected at to a bracket arm 61 sup ported upon the portion 62 projecting upwardly upon the inside of theflush tank and constituting a continuation of the water supply pipe 63. Thesaid lever 16 is slidably pivoted at 64 to .a member 65 having adjustable connection with the upper ensame construction and which operates in the same way as thevalve 26 .illustratedinFig.

3. The lower end of the member 65 iis:pro-. need with a flange. 68, for the same purpose and functionas the flange 39 inIFigQ 3. The portion 62, which, as stated; constitutes a continuationof the supply pipe 63,.is provided with an outlet 0 from which the water is discharged 'from' the supplyipipe. 63

7 into the flush tank 5. The flush tank in this construction. is also provided with anoverfiowpipe 51. g I t V In the construction shown in these Figs. 5 and 6 when the rod is lifted the 'flnger 15 raises the lever 16-to lift therod 66 and open the valve 67 to therebypermit'water to flow through; the supply pipe 63 into the flush tank 5. vNo means is providedrin this construction for automatically cutting off,

the water so that so long the-rod 6 is kept'inraised position the water continues to flow and if such flow continues-long enough will overflow the upper end of the pipe 51. 1 The valve 67 operates to close the opening in the waste pipe 71 in the same manner as described in. connection With the valve 26 and the waste pipe '29inrFig; 3. r

In Fig. 5 the parts are shown inposition with the lever 16 raised so thatthe valve: 67 is in open position while in Fig. 6 the parts are shown in position with such valve in closed position.
