To all whom it may concern:

Be it known that I, WILLIAM F. CONRAN,

ber 157,558, and patented January 8, 1918,

Patent No. 1,253,005, the invention relating to fire extinguishing systems employing a main water supply line or pipe having a number of. outlets or branches at various points controlled by hydraulically operated valves which in turn are controlled from distant points or from. a common operating station by handoperated control valves; and relating more particularlyto a system of movable stand-pipes for buildings such as described in Letters Patent of the United States No. 816,152, granted to me March 27, 1906, but wherein the control pipes leading from the control valves to the hydraulically operated valves are carried within the main water supply pipe or movable stand-pipe, and the present invention relates to the stand-pipe fitting through which the con trol-pipesproject for connection to the hand operated control valves carried thereby, and which fitting is herein referred to asthe control-fitting. 7

As described in my said application and patent, the outlets from the water supply or stand-pipe are controlled from an operating station or chamber, and the controlfitting is placed in the pipe-line. at that point. This fitting may be ofvany suitable shape circumferentially, but I prefer to have the body portion cylindrical in form,-

t'apering toward the ends, and providedwith flanges oflarge diameter. Each-flange is provided with two sets of holes, one setfor the usual bolts for coupling pipe fianges, andthe second set for thepins of a span ner-wrench or turning bar. The body of the fitting is provided with bosses or pro entirely or partly around the bodyJ. Each boss of the upper row is in vertical alinement with a boss of thelower. row, the two alined bosses forming a pair for each control=pipe used in connection "with: the fit ting. Both sets of bosses preferably project through the wall of the fitting at an angle of 45, the upper row projecting upward on the inside and downward on the outside, and the lower row projecting in-the opposite direction. The external diameter of the bosses will be such as to permit them to be bored through and have an internal bore large enough to receive the controlpipes with a surrounding packing material and packing rings. At the central part of the body is a hand-hole with a suitable cap or cover-plate closed watertight with a packing material and bolts. The sizeo'f the fitting will vary, of course, according to the size of piping with which it is employed, and the diameter of the body will vary ac cording to the number of control-pipes employed, and consequently according to the number of outlet-bosses to be provided.

My invention is illustrated in the accompanying drawings, in which Figure 1 is an elevation of the fitting with attached controlvalves; Fig. 2 a central vertical section, and Fig. 3 a central horizontal section.

Referring to the drawings, 1. is the cylindrical body of the fitting tapering toward the ends and terminating in stepped flanges 2 of large diameter. The thicker parts of thesefianges are provided with boltholes 3 which register with bolt-holes in the usual pipe flanges shown in dotted lines, see Fig. 2. The part of flange 2 which projects beyond the pipe flange has a series of holes 4 stand-pipe. The body part of the fitting has a hand-hole 6 which is covered by plate 7 secured by bolts 8, a layer of packing or sealing material being in practice placed between the flange of the hand-hole and plate to make a watertight joint. In casting the fitting itis provided with two semicircular rows ofbosses .9 on the side opposite the hand-hole,"'although if desired, the bosses may extendfarther around the body or en- 'tirely around" it. These bosses are preferably, set at an angle of 45 and extend through the wallcof the fitting and are ovaljections arranged in two rows extending:

,shapedjin cross-section at the exterior end asshown in Fig. 3. Holes 10 are drilled through the bosses to receive control-pipes 11-, the holes being. of larger diameter than the pipes to afiord space for packing ma terial and packing. rings 1,2 and 13; the

former being screwed into the boss from the inside, and the latter havingan. oval flange and forced againstthe'pacliingInaterial by screws 14. As shown the controlpipes 11 (only one being shown in Figl'2) pass downward through the upper bosses 9and' are 'co'nneeted to control-valves 15.

To the inletside of each valve is attached a short section of pipe 11 whiclrpasses through similar packing rings 12 and 13 and fitting, but 'for a valve located below the fit ting-the direction'jof pipes 11 and ll will p'r vedgfiain 3 the control-pipes maybe readily "earned within the main water s'upbe reversed, that is, pipe 11 will" project downwardthrough lower boss 9 and pipe" 11 will "proj ect' upward through upper boss 9.

It'will be observed that with my imply or-standpipe, thus protecting them from 4 damage or disarrangement that the control-valves may be readlly' c'afrried by the litting, and that "the; supply pipe, "control- =pipes and valves may be readily rotated or "moved vertically as explained in my appli- "cation above referredto.
