To all whom t may concern.'

Be it known that I, LOUIS ROOVERS, engineer, of Brussels, in the Kingdom of Belgium, have invented new and useful Improvements in Valves, Stop-Cocks, and the Like, (for which no patent has been obtained in any country except in Belgium the 19th of December, 1885, No. 71,802; in Germany the Lith of February, 1886, No. 86,254, in France the 13th of l\Iay,1886,No.176,115; in Austria the 31st of October, 1886, No. 19,829, and in England the 19th of June, 1886, No. 8,l59,) of which the following is a specification.

My invention has for its object to provide a stop-cock or faucet which will be very efficient in checking the flow, and at the same time be easy of operation; and it consists in certain features of novelty hereinafter described with reference to the accompanying drawings, and particularly pointed out in the claim.

1n the said drawings,Figure 1 is a vertical longitudinal section of a faucet embodying my invention, and Fig. 2 is a sectional plan of the same.

The shell or casing` is represented at a, and the supplypipe at a. c represents a hollow reciprocating plug, whose outer end is closed and provided with an external flange f2,aud whose'side is provided with a number of obliquely-arranged perforations d, which permit of the escape 0f the uid from the said hollow plug. Held within the housing or neck b2 of the casing a by means of a packnut c2 is a suitable packing-ring h, through which the plug c passes, and surrounding the outer end of the plug is a spiral spring f3, which bears against the flange f2 and the end of the housing or inner wall of the casing a. Thus it will be seen that the said spring will have a normal tendency to draw the plug c out of the packing, thereby uncovering the perforations d and permitting the iiuid to escape through the hollow plug and its perforations into the casing a, from whence it runs by the spout. As a means for forcing the plug c back into the housing with its perforations covered by the packing-ring, I

provide a vertical stem or spindle g3,suitably stepped in the bottom of the casing, as shown in Fig. l, and journaled at its upper end in a suitable packing-box b', above which latter it is provided with any suitable operating lever or handle, and secured to this stem is a cam f, which bears in a groove in the outer end of the plug c, as shown in Fig. 1, and thus serves to support the said end of the plug when the latter is forced outward by the spring. The cam has the form shown in Fig. 2, and by which it will be seen that when the spindle or stem g3 is rotated in one direction the plug will be reciprocated bythe conjoint action of the spring and cani, the latter serving to force it in, while the spring serves to force it out. The cam should, however, be rotated in but one direction, and therefore I restrict the rotation of the spindie by means of a ratchet-disk g, secured to the spindlc,and a fixed pawl g,titted to slide vertically in a socket g2, which rests on the said ratchet in engagement with its teeth, and thus the stem is prevented from being rotated in the wrong direction; and, also, the possibility of the action of the spring upon the cam forcing the valve open accidentally is precluded. Supposing, now, the point of the cam f to be bearing against the end of the plug and holding the perforations under the packing, it will be seen that should the cam be further rotated in the direction of the arrow the plug would be suddenly released, whereupon the spring would instantly force it outward into the position shown in Fig. 2. This action would cause a sudden opening, modified slightly by reason of the perforations d being arranged obliquely.

Having thus fully described my invention and in what manner the same is to be performed, what I claim is- In a stop-cock, the combination, with the valve-housing, of a hollow plug open at one end and plugged at the other, iitted to rec-iprocate in said housing and having a number of perforations CZ, a packing-ring surrounding said plug, a fiange on the outer end of said plug, a spring-bearing between said liange and housing and adapted to draw the perfoand tted to slide vertically in said sooket, rated end of said plug out oir: said packing, substantially as set forth. a. vertical stem, a cam ou Said stem ttingli LOUIS ROOVERS.
