" 2 Application filed November 27.1903. Serial 110.182,?60. (No model.)

' To all whom 11!; may concern! Be itknown that I, TnouAs F. CRARY, a citizen of theUnited States, residing in Mid- -dleport, M.eigs county, State of .Ohio, have invented certain new and useful Improvements in Flushing Outfits for Closets; and I do declare the following to be a clear, full,

' and exact description thereof,attention being called to the accompanying drawings, with the reference characters markedthereon, which form also a part of this specification.

This invention relates to new and useful lmprovements- 1n flushing outfits for closets. It consists in general ofaconstruction and arrangement which is particulary well adapted for using water under pressure, such as is derlved from the service-pipes of a waterworks system, although-as to the valve in particular .it is also possible to use this latter in connection with flushing-tanksof customary construction and provided with the usual of the valve in particular and ofparts of the generaloutfit, as will be more fully set forth hereinafter.

In the following specification and particularly pointedout in the claim at the end thereof is found a full description of the invention,

together with its operation, parts, and construction, which latter is also illustrated in the accompanying drawings, in which Figure 1 shows inside view'a water-closet provided with the flushing outfit contemplated by my invention. Fig. 2 is a front view of Fig. 1. Fig. 3 is an enlarged sectional "view of the lower-part of the tank and shows the valve in its closed position. Fig. 4 in a simiv lar view shows the valve open. Fig. 5 18 a is stored in atank12,to which itis supplied by a pipe 13, which may be a branch from the service-pipe system. This water being under pressure requires a constructlon accordingly 7 prevent such.

' of the tank,'which latter is therefore made of sheet metal or boiler-iron, so as to be pressure-proof. By preference I construct it in two parts, a convex front part 12 and a flat vided to check positively the'flowfrom' pipe 13 into the tank. is let out into bowl. 10- for flushing the same The charge from the tank whenever a valve is open, which opening is by'a positive operation, while the closing is arranged to be automatic,thus' requiring no further attention and being secure against neglect by improper manipulation. This valve is a plain disk valve, as shown at 14, and seated on a seat 15, which may be formed on one side of a head 16, which closes the lower end of the tank and is held in place by being attached to a .flanged'neck 17 provided at such lower end. For flushing the bowl this valve is lifted, as shown in Fig. 4, manipulation being by a handle 18. To provide for a copious and quick discharge, the tank is vented at this time, air being admitted through a perforated plug 19 in its upper part. This vent is thereafter automatically closed by a floating valve 21, which when the tankfills again after flushing is lifted by the rising water and pressed from below against a seat 22 inside of the plug. This floating valve guided in its movements by wings 23, and to prevent it from dropping entirely outof the plug when the water recedes during flushing a guard 24 is provided to To guard against any possible leakage in case valve 21 should not close properly or refuse to act altogether, I connect a pipe 25 to plug 19', it being inserted into the vent-openingtherein. Any possible leakage is guided by it into a pipe 26 and conducted by this latter down into the bowl, thus obviating all difliculties arising from flooding. Air for vent purposes may readily enter at the enlarged upper end 27 of'pipe 26, as best shown in Fig. 6. .The flush-valve is caused to close automatically and by gravity, weight being added by water contained in a cup 28, provided above valve 14 and attached thereto in any suitable manneras,for instance,by being screwed onto a boss 29, formed above valve 14. To render the opening of this latter as convenient and prompt as possible, the connection of handle 18to said valve is such that immediately following the first touch of said handle water from above valve 14 is admitted to pass under it, whereby the same becomes at once balanced by the equalization of pressure on both its sides, and the further manipulation for finishing the operation of the lever requires barely an efiort. The details of the means whereby this part of the operation is attained are as follows: Carried by valve 14 and connected to its under side by a stem 31 there is a piston 32, fitted into a housing 33, depending from head 16. Stem 31 is hollow, so that communication between tank 12 and housing 33 is possible, which communication is controlled by an auxiliary valve 34 and normally closed. This valve is carried by a stem 35, fitted into the bore of stem 31 and arranged by grooves so as to present no obstruction to the passage of water through said stem. The lower end of it by means of a link 36 is connected to an arm 37, mounted on a rock-shaft 38, the outer end of which carries manipulating-handle 18. The operation of these means by size and arrangement is such that auxiliary valve 34, being small and presenting no resistance, will open readily as soon as handle 18 is touched to start the manipulation. (See dotted lines in Fig. W'ater will at once rush down through hollow stem 31, filling rapidly housing 33, and press against the underside of piston 32. In the continuation of the manipulation and as soon as the movement of auxiliary valve 34 is exhausted the action will also be against valve 14, which being practically balanced will promptly lift. The manipulation required to obtain the flushing operation is thus practically reduced to a mere touch, the mechanism being'vcry sensitive and responds almost instantl y.

The means whereby valve 14 is caused to follow the movement of valve 34 may consist of a projection or stop on stem 35, or lifting of valve 14 may be caused by the end of link 36 as soon as it comes in contact with piston 32. The end of the operation brings the manipulating-handle only very little over the center of motion, (see Fig. 4,) so that it by its weight presents very little resistance to the closing of the water-weighted valve. This closing takes place as soon as the level in tank 12 has sufliciently dropped and about as shown in Fig. 4, it being noted that the limited supply from the small pipe 13 is insufl icient to maintain the water-level in tank 12 against this rapid escape through the large flush-pipe. Disagreeable noises, checking, pounding, and water-hammer, due usually to rapid moving and closing of valves, are also obviated, since abrupt closing of valve 14 is prevented by the water below piston 32, which acts as a cushion and checks its dropping movement, limiting it to a ratio proportional to the escape oi said water through hollow stem 31 and out under auxiliary valve 34 into cup 28. This latter valve is also the last to close, it being the end of the operation, and follows the closing of valve 14, it being closed by the added weight of handle 18 while dropping to the other side. Valve 14 is guided in its movements by wings 39. Piston 32 may have grooves to receive packing, or merely the water filling these grooves may be relied upon to maintain a tight fit. As will be noted, rapid reclosiug of valve 14 is prevented by the presence oi water in housing 33 and below piston 32 therein, and said valve cannot close until this water is displaced, which displacing is retarded by the restricted passage through hollow valve-stem 31 and through which passage the coniiued water must first pass. A flushing of suliieient duration is thus provided for the closet. Any possible leakage in this part of the device could, however, have no serious results, since it would simply pass into the flush-pipe. A cap 41 is by preference provided to give access to housing 33 and also facilitate construc tion.

Head 16, housing 33, and the upper branch of the flush-pipe 11 may all be in one casting; but this arrangement is not essential. The arrangement and formation of this part of the flush-pipe would alsohavc to suit the style of closet-bowl on which it is to be used.

Having described my invention, 1 claim as new In a flushing outfit for water-closets, the combination of an air and pressure tight, automati call y-ven ted water-tan k, an outlet-val ve in the lower part thereof, a seatior it, aliousing below this seat, a piston fitted into this housing, a lateral outlet from this housing between this piston and the valve-seat, a stem connecting this piston with the valve, a passage t'ormed through this stem and by which the housing below the piston eon'nmmicates with the tank, an auxiliary valve to control this passage, a stem depending from this valve through this passage, a link at its lower end, an arm connected to this link, a rock-sha ft to actuate this arm, an upwardly-inclined leverhandle on the outer end of this rock-shaft, all these means serving to open the valves when said lever is thrown beyond its center so as to incline in opposite direction and a cup on the inner side of the tank-valve adapted to close this latter automatically as soon as the lever-handle is released and serving to return this latter to its normal position in which the same by its weight also closes the auxiliary valve.
