Be it known that- I, JOHN QUINN, a

.citizenof the -United States, residing in the cityof 1Washingto'n, inthe District of Co lumbia, have invented certain new and useful Improvements in Automatic Discharg- 'ers1for Sewage, &c., of which the following 1s a specification, reference being had to the .basement of a building to the sewer level,

and has for' its object-to provide a device Aof this 'character which shallbe automatic in operation, its action being determined by theaccumulation of the fluid or semi-fluid mass in a receptacle -provided therefor, 'shall be certain and reliable, shall be prac# tically noiseless, shall besimple in construction, and shall mvolve no waste of power.

' In accordance with the invention there is provided. at i a suitable point a receptacle vinto which the Huid or semi-fluid mass to bedischargedis permitted to flow and from which it is ejected by the action of a piston driven by steam, water or air pressure from any suitable source or other powers, the movement of such piston as it rises with the accumulation of the sewage on other substance in the receptacle land as it falls under the application of the steam, water `or air pressure to a power piston directly connected therewith determining the operation of the valves which control the admission of the-steam, water or air to the power cylinder.

The invention will `be more fully explained hereinafter with reference to the accompanying drawings in which it is illustrated ina convenient and practical form of apparatus, and lin which,

Figure 1 is a view in vertical, central section of the improved apparatus; Fig. 2 1s a view in elevation, on a larger scale, of one of the controlling valves; Fig. 3 is a view in vertical, lcentral section of the vvalve shown in Fig. 2; Fig-4 is a view of the same partly in elevation iand partly 1n vertical,

central section on aplane at right angles to the plane of section of Fig. 3; Fig. 5 is a view in horlzontal section -on the plane indicated by the '1i-ne 5-5 of Fig. 3; Fig. 6

is a view similarto Fig. 5,-'but illustrating another valve;

Athe `embodiment of the inventionrep-l resented in the drawings, a tank or Areservoir or receptacle a, placed at -a suitable point to receive the sewage or other fluid-or semi-fluid substance to be ejected, is provided with an inlet 5, having an inwardly opening Hap valveb, and an outlet c havmg an outwardly opening flap valve c', the f latter being provided with la weighted ar-m c which serves to preventthe accidental opening of the valve or the o ening of the same except during the 4disch contents of the reservoir or receptacle-.as hereinafter. described.' The reservoir is preferably cylindrical in cross section, although it might be otherwise-formed if desired, and is provided near its top with an inarge of the wardly openmg check valve a and anouty l wardly opening check .valve a2, forthe purpose of venting the upper portion of the reservoir above the piston d. which is arranged to move in the reservoir and is suitably packed.

vIn line with the-reservoir a is :mounted a power cylinder e having a piston -f which is connected with the piston d bya rod g. The cylinder e is provided at its upper and lower endsrespectively with ports and connections c and-'c2 through which air or steam or other fluid' under pressure may be admitted to the cylinder and exhausted therefrom, the fluid under pressure beingsupplied from a `suitablesource through a common pipe h, while the exhaust from the cylinder c is discharged v i through a common exhaust pipe h int the inlet of the reservoir a. The admission of the motive fluid to the upper end of Athecyl- ,inder e for the purpose of driving it down andejecting the fluid from the reservoir, and the exhaust from said cylinder as the piston rises is controlled by a valve It'. It may not always i be necessary to provide means for controlling the admission of the motive fluid to the lower end of the cylinder e and its ex. haust therefrom, but there may bealso a valve m for this purpose. The valve le, and the val ve fm, also, if' it be employed, are operated by the movements of the piston rod g and for this purpose there is mounted upon l a suitable support al 4lever n, sufficiently weighted as ata', to counterbalance the weight of the rod g and pistons 7 and rlhe lever n has a pinjand slot or other suitable engagement with the'rod g, as at n2, and carries a. link 0 to impart movement to the valves 7c and m through arms 7c an'd "mf secured to the stems of. the valves 7,: and m respectively. To permit the valve 7c to re Amain closed during the upward movement of the piston d and to provide for the opening thereof as the piston approaches the upward limit of its stroke, thc link 0 may be slotted,

. as at o, to vengage a pin 7a2 in the arin 7u.

To permit proper movement of the valve m,

asv hereinafter described the arm m ma Aplug 707, secured to have a pivoted toe, as m2, to be operated by a projection o2 carried by the link '0. A

spring ma, if desired, may also be applied to the stem ot the valve m for the purpose of Imoving it ni one direction.

. tionl with the inlet 7&4 and .outlet 7c respectively. The valve m,/if employed, likewise consists. of a shell or casin m3* having in l the wall of its cylinder body an inlet port through its end, as at me,

the lower end' of the cylinder c.

, provided with 45` with the passage m6.

, that the chambered valve plug m7 is secured m4 and an outlet port m5 ,and' a connection with the port e2 in The rotatable,`chanibered valve plug m7 is likewise an inlet port mi and an out-4 let port mi", its open end communicating It will be understood to the stein mato which the arm m is ati Fig. l, with the len .being then similariy positioned.

In the position of the parts represented in pistons d and j at their lowest points, the accumulated contents of the receptacle a,

in communication with the exhaust 71,', the valve m 1 *51S tlf/ll@ sewage or other duid or seinieiiuid accumulates in the tank. u., below the' pist-ond, the latter ting the piston f, 'so that duri., Jrd movement both parts e. and" en to the" exhaust topermit ing pp e2 should o;

' the displacement of the, contents of the cylJ have been discharged. The valve 7a is then in such position as to place Athe upper end of the cylinder linder e.- The slot o in the link o and the pivoted toe m2 of the arm m therefore permit the upward movement of theklink o with the rod g, through the connection of of the valves, but asy the pistons. approach y the limit of their upward movement the flower end of the slot 0 engages the pin 702 mit steam or airor 'other fluid under pressure to the upper end of the cylinder e.

the motive iiuid, driving down with it the tank a through the valve c. The yposition of the valve. 7i: .during this inovement,or during the first part thereof, is clearly indicated in Fig. 5. At a suitable point in the downward movement of the link 0,' withthe pistons, the upper-end of the slot 0 engages the pin 7a2 in the arm 7a and shifts the valve 7c to place the port 701 in communication the "downward movement of the piston f, the valve m, if it be employed, maintains the cylinder e and the exhaust. But in case it should be desirable to cushion the down ward movement of the parts, the valve m 6, with the port ms in communication with the inlet m4, by the action of the projection o2 of the link o' on the toe m2 of the arm m',

is admitted to the lower end of the cylinder. The projection o2 slips byA the toe m2 as it continues its downward movement, permitting the valve to lbe returned by thespring m3 to exhaust position, in readiness for the upward movement of the piston. `As the its pivot and the valve is therefore not affected. Y

lt will now be understood that the improved device or apparatus is not only simple in construction but is certain and direct in operation, that it requires` practically no attention and that it will continue to operate automatically in proportion tothe a'cejected, so long as the necessary motive fluid is supplied. dit will also be obvious that various changes in details of construction and arrangement can be made'without departing vfrom the spirit of. the invention. It claim as my invention: A discharger for sewage, etc., comprising a receptacle having a valved inlet and a valved outlet, a discharge-piston movable in said receptacle, a power cylinder, a pis-l in the receptacle, a controlling valvel at the `upper end ofsaid cylinder, means operated- The piston f is therefore driven `down by' with the etha'ustport 705.
