To all whom it may concern:

Be it known that I, Julius Heltzle, a citizen of theUnited States, residing at St. Louis, in the State of Missouri, have invented a new 5 and useful Improved Stop and Waste Cock, of which the following is a specification.

My invention relates to improvements iu .stop and waste cocks, which are placedin cellars of buildings, having the inlet-water pipe io connected at one end and water-supply for upper stories connected at the other end; and the object of my improvements is, first, to provide means for controlling the water-supply by automatic arrangement between my stop 15 and waste cock and draw-cock of sink in upper stories; also, to disconnect the same, as -will be explained hereinafter; second, to drain said supply-pipe of water to prevent freezing in cold weather,and, third, toprovide ready means 2c in upper stories, by means of which said supply-pipe can be’ drained of water, obviating the necessity of going to basement or cellar of a building, as usual in the old way. I attain these objects by the mechanism illustrated in 25 the accompanying drawings, in which—

Figure 1 is a front view of my improved stop and waste cock. Fig. 2 is a sectional view showing valve with valve stem as seated upon spring for stoppage of inflow of water and the 30 drainage of supply-pipe. Fig.3 is asimilarsectional view showing valve with valve-stem as depressed in itsseat upon spring, bringing orifice of valve on line of orifice of supply for inflow of water through supply-pipe. Fig. 4 is 35 a front view as applied in building, showing my automatic arrangement of rod and lever connected with stem of valve; also showing rod extended to upper story and placed beside draw-cock of sink, said rod having crook at 40 its end, by means of which it is raised by turning the handle of said draw-cock. Fig. 5 is a similar view showing handle of draw-cock turned and engaged with crook of rod at its end, having raised the same, and by means of 45 my automatic arrangement of rod and lever connected with stem of valve depressed the valve in its seat upon spring. Fig. 6 is a front view of valve with stem broken off at end. Fig. 7 is a plan view.

Similar letters refer tosimilar parts throughout the several views.

A is the box or housing.

B represents valve-body, cored out, as shown, having screw ends B² B³, the screw - cap C, coupling D,valve E,and stem F,fitted to oper- 55 ate through the cap audits packing,as shown. To said stem F, I connect rod G, having crook i at its end, through lever 7i, turning on fulcrum 7f,and extend same to upper story, placed beside draw-cock of sink j. The valve-stem F 60 carries the valve E, seated upon spring g,having circular orifice e and channel f (shown in dotted lines,Figs. 2 and 3.) arranged over each other, so that as valve E, through its stem F, is depressed upon spring g by the action of 65 draw-cock of sink j, raising rodG and operating upon lever k through fulcrum 7f, as seen in Figs. 3 and 5. Orifice e of said valve will range inline with orifice of supply-pipe, thereby allowing the inflow of wafer. Again, when, by 70 the action of spring g and the release of drawcock from crook i of rod G,operating upon lever 7i through fulcrum 7t' and stem F of valve E, said valve E is raised to its normal position, channel / presents its opening toward 75 supply-pipe to be drained of its water, and valve at the same time shuts off water from inlet-pipe, as seen in Figs. 2 and 4. The water drained passes out at channel f of valve E through opening cored out of valve-body B 80 for seat of spring g and small hole d, and may from theuce be drained off by pipe connected with sewer, as shown in Figs. 4 and 5.

Screw ends B³ are for connection of watersupply pipes. Their threaded ends receive 85 screw-caps C' and its packing and sleeves b, said sleeves b having tapered ends and flange or shoulder b'. To said sleeves b, I solder supply-pipes at both ends.

To disconnect my automatic arrangement 90 between stop and waste cock and draw-cock of sink, I depress the valve E through stem F in its seat upon spring g, so that its orifice e will be continuous with orifice of supply, as shown in Fig. 3, holding the same firmly iu 95 place by screwing down screw-cap C and coupling D, thereby allowing the continued inflow of water through supply-pipe to upper stories.

It is well known that the water-supply pipes of buildings are more orlessplaced in exposed 100 places, and that the water contained therein is liable to freeze in the fall and winter season,

389,652 causing damage by the bursting of the pipes. It is therefore especially desi rable, in ext reme cold weather, both day and night,: that said pipes should be drained at. all times and wa5 ter-supply thereto controlled. This I have achieved in times of fall and winter season by my automatic arrangement between stop and waste cock and draw-cock of sink, having, by means thereof, full control over water in sup10 ply-pipes, and also drainage of same; also that at other times in spring and summer of the year, when the control of water and drainage of supply-pi pcs becomes unnecessary, I can disconnect the same and render the same 15 inoperative.
