To all-whom it may concern.-

lio it known that I, lvl ciiann J. hKlcCrLoUn, a citizen of the United States, and a resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Siphonic Flushing Apparatus, of which the following is a specification.

My improvements relate to flushing apparatus of the siphon type used in connection with elevated tanks for effecting the temporary flooding and washing out of water closets etc.; and my object is to attain a simple, cheap, solderless structure of few parts, of direct action, and affording the least possible resistance thereto, while easily capable of regulation and control, all as hereinafter fully set forth; the invention consisting in the specific construction, arrangement and combination of parts described and claimed, and distinctive features being the form of the goose neck, the construction of the starter piston and its valve flaps; and of the tube and sleeve for controlling and limiting siphonic action.

In the accompanying drawings,

i b, is my siphonic flushing device, consid ered as a whole. Its stationary parts consist essentially of the discharge tubecl, the goose neck g, the starter cylinderc, and the siphon-break tube 6. The discharge tube cl, constitutes the stand pipe on which the other parts are supported. It is formed with external screw threads cl, (P, (Fig. 2 at base and top; the thread (V, at the bottom screwing into the female threaded upper endofthe coupling pipe a, which latter ex :tends through and Jrojects beyond the floor t, of the tank T.

"Ihe lowerportion of the coupling a, is externally screw threaded. for

engagement with a lock nut a, and the fe male threaded upper end of the flushing pipe 6, which latter extends to. the water closet basin or other article to be flushed.

The. lower end of the throat g, of the goose neck 9, is female threaded for engagement with the male thread (F, on the upper end of the stand pipe (Z, and the lower portion of the inverted trumpetshaped mouth of the goose neck g, is also female screw threaded for engagement with the external screw thread c, upper end of the starter cylinder 0. This inverted trumpet-shaped mouth 9 of the goose neck g, is a peculiar and novel feature of my construction and an rangement of parts, covering and inchiding, as it does, thewhole area of the upper end of the starter cylinder 0, and converging from thence gradually and uniformly into the cross area of the discharge passage 9, g, (Z, so as to present lines of least resistance to the outflow of water from the tank T, as hereinafter set forth.

In axial alinement with the center of the starter cylinder 0, the trumpet shaped mouth portion 9 0t thegoose neck g, is formed with the cylindrical bearing sleeve y, for

the lateral support-and control of the piston rod p, of the starter piston P.

In a simllar manner the inlet port g, for the air'break is positioned 1n the throat g, in approximate axial alinement with the center of the discharge pipe (Z, said inlet port 9, being formed in a nipple cast integral with the goose neck g. The outer extension of this nipple is female threaded for the reception of the externally threaded upper end of the siphonic break tube I), which is pendent therefrom, extending downward parallel to the discharge pipe (Z, to the same level as the open bottom of the starter cylin der 0, or approximately so,i. 6., to a level slightly above the bottom or floor t, of the tank T. j

The siphonic break pipe 6, is provided for the admission of air to the goose neck 9, to terminate siphonic suction therein when the water level in ,the tank T, is lowered to a prescribed level by the discharge of water therefrom. If the break pipe Z), were continuous without opening to tank except at its lower extremity it is obvious that the latter would prescribe the low water level of the tank T; butin order to afford means for regulating the height of this prescribed level, I form said siphonic break pipe Z), either with apertures 0, b If, at diiferent heights, or with one or more continuous longitudinal apertures 6*, (Figs. 5 and G) 'as may be 1ireferred'; and also provide the said break pipe I), with an adjustable regulator sleeve R, by means of which the level ot'air admission to the break pipe may be prescribed 'to meet the varying requirements and exigencies of use.

The regulator sleeve R, is a tube of slightly greater main diameter than the siphonic break tube Z), its upper extremity .being contracted to form a close-fitting .cylindr'ical'bearing portion r, which contacts with the exterior of the break tube snugly, and with suflicient frictional resistance to sustain the sleeve R, on the tube Z). That is to say,-the"regulator sleeve R, is slidable on the air break tube Z), but also suliiciently adherent thereto to admit of its being positioned as desired along the length thereof.

Either end of the regulator sleeve B, may be used to prescribe the low water level in the tank T. Thus in Figs. land 5, the lower end thereof is shown as uncovering the lower apertures I), in one case, and'the lower end of the continuous longitudinal slot 6*, in the other; while in Fig. 2, the upper extremity of the regulator sleeve R, is withdrawn below the upper apertures of the break"tube 'b,'the result being the same in either case in that the horizontal level at which airshall be admitted to the break tube as the water recedes from the tank is prescribed by said regulator sleeve, which thus also, in other words, determines the low Water level of the tank, and hence the volume of water-to be discharged therefrom by siphonie action through the flushing apparatus. 7

The advantage of'the continuous longitudinal slot 6", in the break tube 6, shown in Fig. 5, is that italtords greater scope and delicacy of adjustment of low water level as compared with the apertures b, 6 6 at different heights in said tube Z). I Otherwise: the function of. the regulator sleeve L R, isv essentially the same in either case.

' The upper end ofthe piston rod 79, is connected 'by a link Z, with'the usual actuating lever L. The lower extremity of: the piston rod 7), is screw threaded and engages with the female threaded boss 1), in the center of the cross bar 1) of the annular rim said rim 2), and cross bar 1) constituting the piston base upon the upper side of which are mounted the two flap valves r, These flap valves are die made duplicates, only reversed in position as related to each other. as will be understood by reference to Fig. 5), particularly,the knuckles 2:, 2;, interlocking and being coupled together by pintles g, as shown in Figs. 7 and 8. That is to say, two pintles Q, are used, positioned one on each side of the piston rod p. their inner ends being screw threaded and bent over to pass through holes formed for the purpose in the cross bar p and the protuberant ends of the pintles being then secured by clench nuts y, g.

This construction of flap valve piston is simple, cheap, and efl'ective, being well adapted to the requirements of continuous use in flushing apparatus of this character.

The operation of my improved llushing apparatus is substantially the same as of others of this class, the novelty in the present case consisting essentially in the specilic structure. Thus, the lifting of the piston l raises water into and beyond the goose neck g, thereby starting siphonic suction tor the withdrawal of the flushing water through the discharge pipe (Z,the flap valves r. 1'. of course opening automatically for the purpose when the piston has reached the limit of its up stroke, and remaining open during the descent of the piston to normal position. and as long as the siphonie flow of water is maintained through the starter cylinder c. goose neck and discharge pipe (1. When the water thus withdrawn from the tank lowers the alter level therein to the height of air admission to the break tube 6, prescribed by the regulator sleeve R, air ascends into the goose neck g, and siphonic action terminates; and this is accomplished without gurgling or sucking noise because the air break inlet g, injects the air into the throat g, of the goose neck 9, below the inner apex of the goose neck as shown in Figs. 1 and 2,-this being an important and distinctive feature of my construction of apparatus, and one which renders it practically noiseless in operation in that the cause is eliminated by the introduction of the siphonic air break directly into the downward flow of *ater below the turnin point 9*, as above stated.

It is to be noted that the several parts of my apparatus are assembled and united by screw threads entirely, obviating the use of solder, which is objectionable for obvious reasons; that the whole device is simple both in structure and operation; and that ample provision is made for economizing the use of water and limiting the quantity flushed to the actual needs and requirements of work to be accomplished.
