RANGE-BOILER SPUD.

SPECIFICATION forming part of Letters Patent No. 327,738, dated October 6, 1885.

Application filed October 15, 1884. Serial No. X45570. (No model.)

To all whom it may concern.-

Be it known that T, NICHOLAS STYNE, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Range-Boiler Valves, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of one of my improved range-boiler valves shown as attached to a boiler and connected with the water-back of a range and a sink, the water-back being shown in section. Fig. 2 is a sectional side elevation of the same, taken through the line or as, Fig. 1. Fig. 3 is an elevation of the outer end of the cap. Fig. 4 is a side elevation of the same and a part of the stuflingbox.

The object of this invention is to facilitate the washing out of range water-backs and their circulation-pipes, and to promote convenience in testing the circulation to see if the pipes or water-back are frozen or otherwise obstrueted.

The invention relates to a range-boiler valve constructed with a stock made in two parts, and provided with an end opening to connect with the boiler, two side openings to connect with the circulation-pipe and the waste-pipe, two valve -seats, and a valve and valve-stem, whereby the said circulation-pipe can be c011- nected with the boiler or with the waste-pipe. With the valve-stem and its supporting-box are connected a cap having side grooves and end inclines, and a hollow cyiindrical rotat ing handle having interior lugs, whereby the valve can be readily shifted, drawn tightly to either seat, and locked in place, as will he hereinafter fully described and claimed.

A represents an ordinary range-boiler. B is the cold-water-inlet pipe. 0 is the hot water-outlet pipe, and D is the pipe leading from the bottom of the boiler A to the Waterback E of a range, F.

The valve-pipe is made in two parts, G H, the inner part, G, of which is provided with an exterior screw-thread to screw into the boiler A, asshown in Fig. 2, or with an interior serew-thread to screw upon a coupling secured to the said boiler. The part G is also provided near its inner end with a valve-seat, I, and in its side with an opening, J, having a screw-collar, K, with which is connected by a coupling, L, a pipe, M, leadingto the upper part of the water-back E. The inner end of the outer part, H, of the pipe is screwed into or upon the outer end 01' the inner part, G, as

shown in Fig. 2.

At or near the inner end of the outer part, II, is formed a valve-seat, N, and in its side is formed an opening, 0, provided with a screw-collar, l, to which is secured by a coupling, Q, the end of a pipe, 1%, leading to a sink, S, or other waste-water receiver.

In the outer end of the outer part, H, of the pipe is formed an opening for the passage of the valvestem T, which opening is surrounded by a stufiingbox, U.

Upon the forward end of the valve-stem T is formed or to it is attached a circular valve, V, which is provided upon each side with a circular packing, W, secured in place by a collar, X, or other suitable means, said collar in practice being screwed upon said valvestem.

The valve-stein T passes through the cap Y, which is made with an annular groove in its inner end. The inner part of the cap Yscrews into the stuffingbox U, and serves as a gland to compressthe packing, while its outer part passes over the said stuffing-box as a cap, as shown in Fig. 2.

In the opposite sides of the cap Y are formed longitudinal grooves Z, and upon the ends of the said cap are formed inclines a, the lower ends of the said inclines being toward the grooves Z.

The handle Z) is made in the form of a hollow cylinder open at its inner end, and with an aperture in its outer end to receive the outer end of the valve-stein T. The handle b rests against a shoulder formed upon the valve-stem T, and is secured in place by a screw, 0, screwed into a screw-hole in the outer end of the said valve-stem. The handle 1) turns freely upon the stem T, and is made of such a size as to readily pass over the cap Y. Upon the inner surface and upon opposite sides of the inner end of the handle I) are formed two lugs, (l, of such a size as to enter and slide through the grooves, Z of the cap Y, and engage with the l l i i i l l inclines a upon the ends of the said cap Y1 With this construction when the handle b is pushed inward to bring the lugs d to the innci lugs d to the outer end of the said cap Y the valve \V V \V will be upon the outer valveseat, N. hen the valve \V V \V is upon either Seat, by tn rning the handle Z) slightly the said valve will be pressed tightly to its said seat by the action of the lugs and inclines (Z (r, and will be locked in place. .Vhen the valve is upon the seat I, the passage between the valve-chamber and boiler will be closed and the water from the pipe M will pass out through the pipe G H and pipe B into the sink S or other receiver, producing a strong current and washing out the rust and sediment collected in the water-back E and pipes D M. WVhen the valve is upon the seat N, the ordinary circulation between the boiler A and the water-back E is established.

Another advantage of this invention is that in winter, before starting a fire in the range, by moving the valve to the seat I it can be known Whether the pipes or waterbaclr are frozen or othewise clogged or are open, and an explosion of the water-back from the closing of the pipes thus guarded against.

"Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A range-boiler valve constructed of the pipe hay ing an one opening and two side openings, two valve seats or ports, one seat or port being disposed intermediately of said side openings, and the other at the opposite side of one of the side openings, and two valves on a common stem, said valves being placed between the valve-seats, whereby the movement of the valves may alternately open and close said ports, substantially as and for the purpose set forth.

2. In a range-boiler valve, the combination, with the pipe having valve-seats and connection with the boiler, the circulation and waste pi pcs, valve-stem T, and the water-back, of the stuffing-box U, the cap Y, having side grooves, Z, and end inclines, a, and the hollow cylindrical rotating handle I), having interior lugs, 01, substantially as herein shown and described, whereby the valve can be readily shifted, drawn tightly to either seat, and locked in place, as set forth.

NICHOLAS STYNE.
