HUGH I-I. CRAIGIE, OF STAMFORD, CONNECTICUT.

PLUNGER WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 397,782, dated February 12, 1889. Application filed March 17, 1888. Serial No. 267,564. (No model.)

T0 whom i6 may concern:

Be it known that I, HUGH l-I. CRAIGIE, of Stamford, Fairfield county, Connecticut, have invented certain new and useful Improvements in Plunger ater-Closets, of which the following is a specification.

This invention relates to water-closets to which water is admitted directly from the service-pipe through the medium of a selfclosing valve of the type known to the trade as variable chamber-valves, or other suitable valve, which, when its stem is pressed, is opened, and which closes slowly of itself, thereby admitting the flow of flushing-water for a certain duration.

My invention is especially applicable to plunger-closets or other closets of analogous construction which are flushed through such a valve.

Plunger-closets have heretofore been made with a lever arranged to be vibrated by the lifting of the plunger and when so vibrated 1 to press in the stem of a self-closing flushingvalve in order to start the flow of water to flush the closet. According to my invention this valve-operating lever arranged wholly within the plunger-chambor, and is fulcrumed to the cover of said chamber, so that by the removal of the cover the lever is removed and the plunger maybe freely lifted out. My invention provides also a novel means of varying the length of the flush by an adjustment of the fulcrum of the valve-operating lever, and this adjustment may be made with great facility to any length of flush between the extreme limits. By one feature of my invention this adjustment is effected wholly from the exterior.

In the preferred embodiment of my invention I form the plunger chamber with a pocket or wing projecting to one sidepreferably to the front-and I connect the selfclosing or variable chamber-valve to the under side of this pocket with its stem projecting into the cavity thereof, and in the pocket I mount a pivoted dog or lever-arm with its free end resting on the end of the stem. The operating-lever is fulcrumed in a standard fastened to the under side of the cover of the plunger-chamber, and is arranged with its long arm normallyprojecting downward and resting on the plunger and Fig. 2 is a side elevation thereof.

With its short arm standing over the pivoted dog, so that When the plunger is lifted the consequent tilting of the lever causes its short arm to press down the dog, and consequently to press down the valve-stem, so that the valve is opened. The lever and dog are so constructed that by the adjustment of one or the other in longitudinal direction the duration of the flush may be altered at will.

The accompanying drawings show my invention as applied to a plunger watercloset of a wellknown type.

Figure 1 is a front elevation of the closet. Fig. is a fragmentary plan thereof, the cover of the plunger-chamber being removed. Fig. 4 is an inverted plan of the cover of the plungerchamber 011 the same scale as Fig. 3. Fig. 5

i is a vertical section, cut on the lines 5 5'in Figs. 3 and 4:, of the upper part of the plunger-chamber and the valve and its operating devices, the plunger being depressed; Fig. 6 is a fragmentary view of a portion of Fig. 5, showing the operating lever tilted by the elevation of the plunger and with the parts adjusted for a short wash. Fig. 7 is a similar view to Fig. 6, but showing the parts adjusted for a long wash. Fig. 8 is a rear elevation of the standard M, partly in section, showing the dog J turned into an upright position.

Referring to the drawings, let A designate the bowl of the closet; B, the plunger-chamber; O, the outlet or soil pipe; D, the plunger;

E, the rod or spindle thereof, and F the pull- H handle or knob. These parts are all in general of the usual construction, and, except in the particulars hereinafter referred to, will need no description.

G is a self-closing flushing-valve of a wellknown type, being of the kind known to plumbers as a variable chamber-valve. The service-pipe a is connected to this valve, and a pipe, 1), leads from the valve to the flushingconnection 0 of the bowl, which communicates with the flushing-rim thereof in the usual manner.

The plunger-chamber B is formed on one sidepreferably its front side-and at or close to its top with a lateral projection or pocket, B, the bottom of which is preferably level and the interior of which communicates freely with the interior of the plunger-chamber. The cover H of the plunger-chamber is formed with a corresponding extension 011 one side adapted to cover over and close this pocket.

Referring to Fig. 5, the variable chamber or self-closing valve (l is supported by screwing a threaded neck, (7, formed at the upper end of its shell 71, into a threaded hole formed in the flat bottom or floor of the pocket- B. The valve G is formed with two shells, h and h, screwed together, the lower shell having the cylinder in which works the usual cupleather piston e and the socket beneath for holding the closingspring f. The piston e is mounted at the lower end of the valvestem I, which passes up through the neck d, and the upper end of which projects into the pocket B. This stem carries the valve-disk g, which closes against the seat in the diaphragm crossing the shell 71, and which diaphragm separates the inlet-port beneath it, communicating with the service-pipe a, from the outlet-port above it, communicating with the flushing-pipe b, all usual in valves of this character. The operation of such valves is well known. \Vhen the stem I is pressed down, it carries down the valve-disk g with it, thereby opening the water-way, and also presses down the piston c, which allows the water to escape from the chamber beneath it by flowing past its collapsible leather packing. \Vhen the valve is released, the spring f, which has been compressed, presses upward. on the valve-stem I and tends to close the valve'disk g, its action being resisted by the suction of the piston which is held down by the atmospheric pressure and can rise only as fast as the water from the space above it can escape down through a minute orifice into the chamberbeneath it, so that the valve closes slowly to its seat, and the time consumed in reseating itself proportional to the extent to which the stem I was pressed down.

By the connection of the shell of the val ve,

G to the pocket 13 in the manner shown any leakage which may occur from the valve around the valve-stem. will escape into the pocket 13, and thence into the plunger-chamber, and will do no harm, so that it is unnec- -ssary to pack the neck (.Z through which the valve-stem passes. Within the pocket 15 is arranged a pivoted dog or a lever-arm, .l', the free end of which rests loosely on the head of the stem I, its upper side being beveled at j, as shown in Figs. 5 to 7.

K is the operating-lever,which fulcrumcd. to a standard, L, which is fastened to the under side of the cover H by means of a screw, Z, passing through a slot, in, in the cover, engaged by a nut, 12, on the top of the cover. The standard L, when the cover is applied, comes into the upper part of the pocket 13, and the short arm 7.; of the lever K stands directly over the inclined end j of the dog J. The long arm 1) of the lever K projects into the plunger-chamber B, and its outer portion is forked or slotted at 12', so that it passes on opposite sides of the plunger-rod E. When the plunger D is elevated. by pulling up the handle F, the lever K is tilted up, as shown in Figs. 6 and 7, thereby moving its short arm 70 downwardly against the dog J and pressing the latter down, and conseqilcnt'ly pressing down the stent I of the flushing-valve G. It. will be observed that when the lever K is thus tilted. the under side of its arm k stands at an incline, as shown in Figs. ti and 7. Itishence obvious that the extent to which the dog J shall be depressed by a given movement of the lever K depends upon relative positions of the lever and dog, so that the free end of the dog comes nearer to or farther from the fulcrum of the lever K. The nearer the part of the dog which is acted on by the lever comes to the end of the arm 7; the lower will it be depressed, and consequently the wider will the valve G be opened and the longer will. be the flush. Conversely, the closer this part of the dog is to the fulcrum of the arm 7.: the less distance it will be pressed down and the shorter will be the .flush. A. means is thus provided for readily determining the length of the flush by effecting a suitable adjustment of the lever K and dog J relatively to one another. This is accomplished in the construction shown by an adjustment; of the fillcrum of the lever K. This lever is shown in Fig. 5 in its intermediate position. This adjustment is effected by moving the standard IA farther forward or rearward in the slot m in the cover Il'.

Fig. b shows the lever adjusted to its extreme forwz'trd position, so that it gives the shortest possible flush. This adjustment is made entirely from the exterior, and without necessitatii'ig the removal of the cover if, simply by partially screwing the nut a, sliding the standard I. tin-ward or back as far as may be i'lecessary to give the desired result, and then retightening the nut 11.

In the constructitm shown it is the upper edge of the incline} on the dog .1 that isacted upon by the arm 7.'. It is obvious, however, that the arm I; may be made to act upon any part of the dog J to substantially the same effect by properly shapin the parts relatively to one another. The lower side or face, it, of the arm constitutes in effect a camsurface, and may be straight or curved, as preferred; or the inclined face j on the dog may be employed. as a cam-surface and the arm 7.: be made to make contact wit h it in its movement without in any way altering the operation or the dog J may be made adjustable, instead of the lever K, it being immaterial to my invention which of these parts is adjustable so long as the proper relative adjustment is obtained.

The lever K is provided with a butter, q, of soft india-rubber or other suitable material, the function of which. is to suppress noise in case the lever K should get into contact with the cover ill by the lifting of the plunger too high.

series The dog J is preferably constructed of U shape, as shown in Fig. 3, in order to admit the lever K between its legs when the lever is in the position shown in Fig. 5. The dog J is pivoted to a standard, M, which is fastened by a bolt or screw, r, to the floor of the pocket 13', and which also is of U shape, having vertical arms or standards projecting from its l; ase-plate and perforated to receive pivotal lugs s s, projecting outwardly from the legs of the dog. The dog and its standard M are pivotally connected by squeezing together the legs of the dog far enough to enable its lugs s .5- to be entered between the upright arms of the standard M, after which the legs of the dog are pried apart to their normal position, the lugs-being simultaneously entered into the bearing-holes in the standard. This makes a cheap and simple construction, which will endure indefinitely. The parts may be put togetherbefore the standard M is fastened in place, since the open form of dog enables ascrew-driver to be thrust between its legs for turnin the screw 7'.

Fig. 8 is a rear elevation of the standard M,

partly in section, showing the dog .I turned into an upright position.

The principle function of the dog J is to transmit the (.lownward pressure of the lever K to the valve-stem I, it being so arranged relatively to the valve-stem that its motion, which occurs, of course, in the are of a circle, is but slightly divergent from a vertical line, and consequently practically all tendency to tilt the stem I or thrust it sidewise is averted. The stem I might be acted upon directly by the lever-arm 7;, except for the disadvantage of the side thrust of this arm, which would tend to bend the stem sidewise. Such an arrangement would also render the adjustment of the leng'l h of the flush by shifting the f ulcrum of the lever practically difficult or impossible of accomplishment.

My invention is not necessarily confined in its application to plunger-closets, but maybe applied to any closet flushed by a valve of the self-closing order controlling the passage of water from the service-pipe, and which has a lifting handle or knob and its rod through which motion may be communicated to the lever K in the act of flushing the closet in analogous manner to the action of the plunger D.

I claim as my invention the following-deiined improvements in valve-flushed waterclosets, substantially as hereinbefore specified, viz:
