QUCK-DETACHABLE VALVE.

Specification of Letters Patent.

Patented Dec. 25, 19t?.

Application filed March 31, 1917. Serial No. 158,830.

To all lwhom it may concern.'

Be it known that GOOD S. JOHNSON, a citizen of the United States, residing at Dixon, in the county of Solano and State of California, have invented new and useful Improvements in Quick-Detachable Valves, of which the following is a specification.

This invention relates to a quick detachable valve of the ball-cock type.

Float-actuated valves such as are generally employed in connection with flushing tanks and the like are as a rule constantly submerged in the water or other liquid contained in the tank, and as such are subject to corrosion and natural wear. Itl therefore often happens that these valves must be removed for repair or adjustment, and as they are generally screwed into the bottom ot deep and narrow tanks, it will readily be seen hat their removal is accomplished with considerable diiiiculty and loss of time, this being particularly true when itis necessary to disconnect and remove projecting float levers and the like before it is possible to turn or unscrew the valve proper. i

An object ot the present invention is to overcome this ditliculty by providing a simple, substantial, quickly detachable valve which can be readily removed without turning the valve or disconnecting the fioat le'ver or any other projecting part.- Further objects will hereinafter appear.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure 1 is a central, vertical section through the valve, showing it positioned in a flushing tank.

Fig. 2 is a cross section on the line 2-2 of Fig. 1.

Referring to the drawings in detail, A indicates in general a valve of the ball-cock type. The casing ot the valve is in this instance constructed of two separable sections, as indicated at 2.and B.- 'l`he lower or male section is provided with a valve seat 4 in the upper end and an exterior flange or shoulder 5 engageable with a. gasket placed in the bottom of a tank G. The lower end of the casing 3 its-extended and threaded, as at 7, to receive a packing gasket 8, a clamping nut 9, and a slip joint l() of standard construction to receive the pipe 11 through which water under pressure is admitted. The upper casing or female section 2 is provided with a cylinder extension l2, in which is slidably mounted a piston 13 Supporting a valve 1l. of the usual type which is engageahle with the seat el; the valve being:r normally held against the seat by means ot a float-actuated toggle lever 15.

Formed as an extension of the annular shoulder 5 is a hook-shaped lug 16 having its mouth horizontally arranged and facing the male section, and formed on the lower end of thc upper casing section is a lug 17 which is adapted to be received in and through the sides ot' the mouth of the hook-shaped lug 16. Formed on the annular shoulder 5, on the side opposite to the lug 16, is a pair of lugs 18, in which is pivotally mounted, as at 1E), a screw 20. Formed on the upper casing section, in alinementwith'the lower lugs 18, is a pair of lugs 2l, between which the screw is adapted to pass, and carried by the screw is a wing-nut 22 which cooperates with the lugs 16 and 17 to clamp or secure the casing sections together, a gasket 23 placed between the casing sections forming a waterproof `joint.

The majority of valves of the type here employed are generally provided with a single valve casing which is screwed into the,

bottom of the tank. This causes considerable trouble as it is often necessary to remove thevalve for repair, adjustment or the renewal of parts. In order to remove a valve that is screwed into the bottom of a tank, it is necessaryvto remove the float member; and as this cannot be removed without taking out one or more of the pivot pins in the toggle lever, it can readily be seen that considerable time is lost as the valve proper is constantly submerged in the Water contained in the tank, causing the pivot pins to corrode to such an extent that it is almost impossible to remove the same. rl`he necessity ot' removing the float lever is caused by the 'narrowness of the tanks vusually employed. 1n other words, it is impossible to unscrew the valve casing or remove it without removing the float member as it would Abe impossible to turn the valve casing to unscrewl the same.

The present invention entirely overcomes this difficulty as it is only necessary to partly unscrew the nut 22. This permits the screw 2() to be swung about its pivot 19 away from the lugs 21 and thereby permits the upper valve casing to be removed bodily without turning the saine or disconnecting any of the projecting parts or levers. rThe only parts subject to wear, such as the valve lll and piston 13, together with the float and toggle levers, can, therefore. he removed without further disconnections and practically without any loss ot' time as the screw 2O eniployed is so large and so easily reached that no difficulty `is encountered when this is released. The 4valve is olherwise operated in the usual manner; that is. the witlnlrawal ot' water from the tant: causes the float to drop andv tliereh permits the toggle lever to open valve le." .--fater from the pipe. ll will then pass throi gli the lower and zippercasingv section and wi l ihrongh 'i l men enter the laid;

a discharoc nozzle 25; the valve bei i@ antoinalicall'v closed when the float :H3 reaches a predetcrinined elevation or when lh'e desired water level obtained.

The. materials and finish of the several parts ot the device are sach as the experience and .indgn'icnt ot the manahn-larer may dictate.

l wish it understood that vai-ions changes in form, proportions and minor details of construction may he resorted to within the, scope ot the appended claim and that l do not wish to liniit myself to the sperilie dea sign and construction here shown.

Having thus described my invention, What l claim and desire to secure by Letters Patent is* In a quick detachable valve, a male section having a peripheral flange extending out there lrom and between its ends, said flange heine tornied so as to provide vertically alined gasket seats on its opposite side faces, gaskets engaged with said seats, a valve seat on one end of said section, a. valve-bearing l'emale. section received over said end of the male'seel'ion and seated on the adjacent gasket. seat, a hook connected to the flange periphery and extending upwardly and curved inwardlyy and having its mouth horizontally arranged and Vfacing the male section, a radial lng extending outwardly from the l'emah eer ion and having its end shaped to he received in anil through the sides of the hook meal h. and a screw connection between :he periphery` ol' said flange and the other sertion lo hohl the sections against moverment.

ln testimony whereof l have hereunto set my hand in lhe presence of two Subscribing witnesses. v
