SLOW-CLOSING COMPRESSION COCK.
Patented my 9,1876.

MINEORD s. CLARK, 0E NEW YORK, N. Y., AssiGNoR-fro oHA'RLEs-j EARRIsoN, oE SAME PLACE.
`IMPROVIVl-ENT IN SLOW-CLOSlNG COMPRESSlON-COCKS.
Specification forming part of Letters' Patent No.*l77,095, dated May 9, 1876-; application lled December 2, 1875.
. plugis raised by atmospheric pressure when the plunger is raised by its loperating-screw, and as' the fluid makes its way into the recess of the plunger, the `loose plug f'alls by its own weight until it engages the valve-seat, whereon it is held by the waterpressure.
In operating this class of' compression-cocks the stem .is first turned in one direction t0y force the main plunger down, so as to lcompletely envelop the loose plug, and is then turned the other way, to elevate the plunger and loose plug together.
My invention consists in the combination' f of' the plunger with an adjusting-screw, t'or regulating the operationof' the plunger by stopping it at prescribed points. My improvement makes the structure an adjustable sel'fclosing valve. The higher the plunger is elevated the longer it takes for the loose`plug to move down to the valve-seat, and of course the longer the water continues to flow through the valve. .v
In the accompanying drawings, Figure l represents-a vertical section of my improved compression-cock, through the center of thev valve-chamber, and the'induction and eduction passages. Fig. y2 is a similar vertical section of the valve-chamber, showing the plunger and. loose plug elevated. Fig. 3 is.
an elevation, partly in section, showing the screw-thread on the plunger.
Theinduction-passage a communicates with the bottom of' the valve-chamber b, which has the central outlet c provided with the raised vannular valve-seat d, through which liquid is discharged into the nozzle e of' the cock. The
plunger fis elevated and vdepressed by the` usual ways.
In the drawing the plunger is represented as havingztwo male screw-threads,f1 and f2, upon its periphery, which engage corresponding female th reads f3 and f4,formed in the walls'of'the valve-chamber. The plunger is provided with a cylindrical recess, h, which contains theloosefitting cylindrical plug, i, provided at its outer or lower end with the elastic washer i. rIhe upper end of' the plunger is provided with the square stem K, which is engaged by the corr-espondingly-shapedl recess K', inthe lower end of they valve-stem. low, for the purpose of containing the adjusting-screw l, the lower end of which engages the upper end of' a loose piri, ll, contained in the lower part otl the opening-in thevalve-stem. The lower end of' the pin l* is provided with the' annular washer l2, which engages the iuterior wall ofthe hollow valve-stem, and makes a tight joint, f'or the purpose of` preventing the escape of' fluid from the valve-chamber into and through the hollow valve-stem. The lower-end ot the pin l1 engages the upper end of the plunger-stem K, and acts as a stop,
whichdetermines the distance to which theV plunger' can be elevated,
rlhe operation of my compression-cock 1s as follows: The parts being in the position show n in Fig. l, the stem is turned from right to left, which depresses the plunger, so, that it completely in'closes the loose plug. The Y stem is then turnedback from lef't to right, which elevates thev plunger, and at the same time elevates the loose plug by atmospheric pressure, theparts thenk assuming the posi- Ation indicated in Fig. 2.k In this position the fiuid gradually makes its way around the periphery of' the loose plug into. the recess in The valve-stem is holthe amount of upward movement of the plum. tially as" described, in combination Witllhll d rger, andcconseqilently.of fthe `loose plugfisi `tdjl'lstbleistop"lforthemiupoeelof;regulating g perfectly controlled, and thereforeithe time the height to which then-plunger fri-iid Aloose` `required for the dropping` of'` the loose plug is` plugean be elevated, and thus `determining g.
