STAND-PIPE svsrmr.
To altwhom'it may concern:
Be it known that I, WILLIAM F. CONRAN,
a citizen of the United States of America,
residing in -the borough of Brooklyn :of the city of New -York, in the county of Kings and State of New York, have invented. a certain new and useful Improvement in Stand-Pipe Systems, of which the following is a specification.
My invention relates 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; and my invention relates -more particularly to 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 27th, 1906, and embodies new features and details in construction as hereinafter morefully set forth.
In the "accompanying drawings which illustrate my invention as applied to a movable stand-pipeFiglure 1 is a diagrammatic .view representin t e front wall of a building and the'stan -pipe with its water supply connections Figf 2, an enlarged vertical sectional view of the hydraulic-lift; Fig. 3, a sectional view of the base or restfor the stand-pipe; Fig. 4, a vertical s ctional view of the control-box or fittin Fig. 5, a central cross'section of half 0 the control-box fitting; showing the covering .plate'for the handtrating the arrangement of control-valves; Fig.7, a central vertical section through the nozzle-valve and fitting; Fig. 7 an enlarged vertlcalsection .of the'expansion joint shown in Fig. 7; Fig. 8, a .horizontal section. on

chamber where the valve controls are located. The standipe 6 extends from the cellar to the roof 0 the building through guides or bearings 7 secured to the floors or front wall, or both.v At each floor and cellar, excepting the ound floor, are shown nozzles 8 mounted on nozzle-valves 9, which in turn are mounted on Y-fittings 10 of special form. Each of these fittings also has mounted thereon a hand-valve 11 to which is attached the ordinary hose line'12. In the section of the stand-pipe passin through the operating chamber is inserte the control-box or fitting 13 upon which a series of hand-valves 14 are mounted for controlling the flow of water through the control-pipes 15 extending to each nozzle-valve 9. Mounted on the stand-pipe above the 'control-fittin is a pointer 8 whose position as to heig 1t and direction corresponds to the position of the nozzles. These control-pipes are carried within the stand-pipe and project through the control-fitting for connection to valves Y as follows: first, the Siamese coupling and pipe 18 for fire-engine service, second, pipeline 19 for awater-tank service; third, pipeline 20 for connection to'a pum' in the buildto the regular street-water main or a highpressure service. These supply lines connect with ipe 22 which enters the hydraulic-lift cylinder at the bottom, and in each of these lines is placed acheck-valve 23 which per-- mits flow of water only in the direction leadin to the stand-pipe. From pipe 22 bxten s' a small supply pipe 24 which is connected to one port of a. 4-way valve '25 in the operating chamber and from two other ports of this valve 27 which lead, respectively, to the: bottom and top-of cylinder 17 for supplying pressure imder and above the piston in said cyl- "for raising and lowering the standpipe. The fourth port tqga'ny suitable point for discharge.: .The
I ud-pipe may berotated in either direction, and for this purpose I provide a lever or large spanner wrench 29 engaging pinext end pipes 26'and 'f 'valve25 has at- 28 which may l'ead 90 ingfand fourth, pipe-line 2 1 or connection holes in the flange of the control-fitting. In practicethe stand-pipe will enerally be located as shown near the wal of the building and in such case the nozzles need swing only through an arc of 180. The arrangement of supply pipes leading to pipe 22 as shown is on] diagrammatic, and it will be understood t at in practice they will be located in the most convenient manner and so as not to interfere with the operation of or obstruct the stand-pi e or nozzle in the cellar. The same remar apply to control- pipes 24, 26 and 27, and these will usua ly be placed against the wall of'the o crating chamber. The pipe leading from t e Siamese coupling 18 is provided with a drain valve 30 and supply line 19 is referably provided with a gate-valve 31. t will be understood that the positions of the nozzles, the nozzle-valves and fittings, relative to the floors or ceilings, as shown, are not the positions they will be in in actual practice; the positionsshown being only for convenience of illustration. In practice the nozzles will be located near the ceilings when the stand-pipe is in its extreme elevated position, and the extent ofivertical movement will be governed by the height from floorto ceiling of the lowestceiling of the building-and the downward movement will be limited by the stop-base 16 striking the top of cylinder. 17. This prevents the piston of the hydraulic-lift striking the bottom 'ofthe cylinder. Whenno water is under the piston, the stop 16 will rest on the top of cylinder 17 and all of the nozzles and fittings will be in their lowermost positions. Whenthe pipe is not in operation, the cyl inder may be filled with water under the piston to maintain the stand-pipe in its elevated position. The water for this purpose will be supplied from the house tank through control-valve 25 and 'ipe 26. If.
preferred-a mechanical stop not shown) may be provided in the operating chamber for locking-the pipe in the elevated position after. being raised by the lift, and then valve 25 may be turned to open the drain der by .a hand pump.
Beferrin to Figs. 2 and 3 of the drawings, it will be noted that cylinder 17 is of triple thickness, the inner shell or cylinder beingofbrass or other non-corrosive metal and between the innerand outercylinders is a lining of any suitable material, such for instance ascement. The outer cylinder is screw-threaded at both ends, and the lower end is screwed-into a flange on the base plate 32 and the upper end screws into a collar 33. The base plate has a central hole and flange. .34 into which is screwed anipple 35 and to which supply pipe 22 is connected within cylinder 17 is a pipe 36 also screwedinto flange B4 and extending height oi the ort and the water drawn out of the cyhii;
cylinder. The standipe 6 is screwed into the reduced flange 0 base 16 and screwed into a second thread is a pipe 37 of larger diameter than pipe 36. his pipe 37 extends downward as a continuation of the stand-pipe and surrounds the pipe 36. The lower end of pipe 37 carries piston 38. This piston slides on pipe 36 and in contact with the inner shell of cylinder-17. The piston 38, as shown, is provided with a softmetal inner sleeve 39, and a suitable packin and packing ring 40 for making a tight siding fit on pipe 36; and for a watertight slidin fit with cylinder 17, the piston is provide with upper and lower packings and pack-' ing' rings 41. At the top of the cylinder, pipe 37 slides in a similar soft metal sleeve 42 and packing and packing ring 43 within collar 33. This collar is provided with a flange 44 upon which the flange 45 of the base 16 rests. Supply pipe 26 enters the bottom of cylinder 17 through base 32 andsupply pi e 27 enters the top of the cylinder throug collar 33. The entire structure is supported upon a concrete foundation 46. From the foregoin description of the parts comprising the hy raulic-lift it will be ob-' served that the main water supply for the stand-pipe flows directly from the supply pipe 22 and 36 into the enlarged downward extension 37 ofthe standipe, and that the telescoping connection t as formed and combined with the lift permits free rotary and vertical movement of the stand-pipe, and without being hampered by the water supply connections. This arrangement also permits rotary movement (if thestand-pipc to any desired extent according to its location, or if located in the center of a building, the pipe may be given a continuous rotary movement and at the same time an inter mittent or contlnuous' vertical movement and thereby reach all parts of a floor withimthe' range of the water:
In Figs. 4, 5 an e the 0O11t Q1Tfitti1lg13 is shown in detail. This fittingmay be of any suitable shape, but as shown,'I- prefer to have-j the body .portion cylindrical 'in' form and taperin toward the ends; and rovided with steppe flanges 47 of large iarneter;
At tlietliicker part of these flanges I rovide bolt-holes 48 which register with be t-holes 50 which is covered'by plate 51' secured by bolts '52. In casting the fitting it is pro? vided with two semi-circular rows of bosses 53 on the side opposite the hand-hole; These bosses are set 'at an angleand extend'through the wall' of the fittingand are oval-sh jrjked in cross section at the exter or end. 'ey
have holes 54 (Fig. 6) drilled throu h to receive the control-pipes 15, the holes eing of larger diameter than the pipes to. aflord space for packing material and packing rings 55 and 56; the former being screwed into the boss from the inside, and the latter having anoval flange and forced against the packing material by screws 57. As shown 'the control-pipes (only one being shown in Fig. 4) pass downward through the upper bosses 53 and are connected to control-valves 14, it being understood that a control-pipe 15 and valve-14 are provided for each nozzlevalve to be controlled, and that each such pipe and valve is independent of the others. To the inlet side of each valve is attached a a short section of pipe 15". which passes through similar rings 55 and 56 and packing material in the lower boss 53 and to this spective nozzle-valve 9.
Details of construction of the nozzlevalve 9, Y-fitting 10, and the control-pipe supports are shown in Figs. 7 and 8. In my atent No. 816,152, the valve and fitting.
are combined in one structure, but that construction is not suitable for the arrangement having the control-pipes located within 1 the stand-pipe, and I also found that it was important to provide a nozzle-valve which would not obstruct the'flow of water to the-nozzle. To accomplish the latter object I designed the valve so that when opened the seat would present no obstruction to the flow and the valve disk would be withdrawn entirely from theepath of'the Water. In carrying out this construet'mn I- make the waterway '60, of, the valve in--v straight cylindrical form, screw-threaded at one end to screw into the Y-fitting 10 and the other end having1 a flange 61'. valve seat 63, valve i'sk 65 and its stem are setat an angle of 45 to the waterway and these parts are housed in a. cylindrical body 62 and 64 forming a Y with waterway 60. This body 62 and 64 is larger in diameter than waterway and part 62 forms 'an annular enlargement at art 60 in which the valve seat 63 is remova 1y secured; the depth of the enlargement being such that a the valve seat does not project into the. path of the water and actually presents an opening larger in diameter than the waterway 60. The inside diameter of. cylinder 64 is slightly larger than the -diameter of valve 13, the direction of pipes 15 and 15" The disk 65, and the cylinder terminates in a flange 66. .Mounted on cylinder 64 is the \piston cylinder 674 having a flan e 68, the two flanges 66 and 68 bein bolted with a packing materia between them. Cylinder 67 is closed at the inner endfby partition 69 havin a hole. for the valve stem 70. On the va ve side of the partition 69 is an annular extension 71 which forms .stufling-box to receive a packing material for the valve stem, and 72 is the" acking ring. In the piston cylinder is a piston 73 secured to the end of valve stem 70, and betweenthe piston and the closing cap 74 is a coiled spring 75. One urposeof this spring is to hold 'valve65 to its seat when'no water is in the standpipe and insure its being in the closed position when water stem with the valve-disk attached thereto is passed through the stufling box on partition 69, and the piston 73 is then attached to the stem; the packingmaterial and ring-72 are then placed in position; packing is then placed on the flange 66, and valve-disk is inserted in cylinder 64; flanges-66 and 68 are then bolted together, and finally spring 75 and cap 74 are placed in position. The area of plston 73 1S slightl p the area of valve-disk 65 so t at when water is admitted to cylinder 67 through cont-rolpipe 15, the pressure. thereon 'jWill exceed the Water pressure on disk 65 plus the pressure of spring 75 and open the valve. When the pressure on the underside of piston 73- is relievedby shutting off the water supply at its respective control-valve 14,-. and openg the drain port thereof, spring-'75 will start twelve-disk toward its. closed position-land the spring pressure plus the water pressure on the back of thevalv'e-di-sk will finally close .the valve and holdeit closed until pressure is again admitted to cylinder 67 through pipe 15.
7 In thepatentabove referred to, the nozzle is mounted directly upon the. nozzlevalve, but in the present arrangement I em.- ploy a flanged ofi-set fitting '7 9 upon which the nozzle is screwed and by means of which the nozzle is held at an angle. These fit greater than together tings in practice will be made with off-sets having varying angles to meet varying conditions.- The nozzle 8 may be of any'ap-,
proved form, but I provide it with an ex':
terior screw-thread 80 to take standard hose couplings. The object of this is to permit -quick attachment'of an extra hose line to the stand-pipe without the necessity of first removin the nozzle.
The -fitting for the nozzle-valve has a semi-cylindrical or U-shaped central section (see Fig. 8) presenting a. flat sidewhich is covered by a plate 81, secured b bolts, and the joint being leaded or packe The diameter of, the central section is greater'than the stand-pi e, and tapers at both ends. The ends 0? the fitting are screw-threaded to receive the screw-threaded ends ofpipes 6. The Y-branch 82 projects from. the U-shaped body portion of the fitting in a direction parallel with the flat side V fitting 10 at each floor for connection to a nozzle-valve, and as shown in Fig. 7, the fitting for this purpose has a. boss at the upper angle of the Y-branch 82 which is bored and packed in the manner described in connection with the fitting of Fig. 4. .As hereinbefore stated. the control-pipe for an'ozzle-valv'e in a cellar, or one located below the control-fitting 13, will extend downward and the connections at valve 14 will be the reverse of the connections shown in Fig. 4.
For leading pipe ,15 out through fitting 10 I .in the cellar the pipe. may have an upward bend and pass up through the stufling-box for connection to the piston chamber 67. I prefer, however, to provide a boss 10 through which pipe 15 (shown' in "dotted.
lines) will pass; the boss in such case being.
' inder 67 when necessary.
At the upper end of fitting 10 and above the entrance of the Y-branch are two rows of lugs 84 between which are held two from above the joint, and the lower extension forming one member of a union for attachin the control-pipe section enterin the joint from below. The union end '0 the expansion-joint includes a nipple 88 having its inner end ground conical or spherical to seat against the correspondingly ground end of the box extension, and this nipple has a flange which is en aged by cap 89 and whereby the nipple ishe d to its seat. The upper ends of the control-pipe sections are screwed into the nipples and thuseach section of control-pipe is supported or suspended by the union ends of the expansionjoints. By this means each section of control-pipe is free to contract or expand lengthwise without straining joints or bowing the pipes, and at the same time the expansion-jolnts and retaining plates support the control-pipes and hold them in position against the interior of the stand-pipe and prevent lateral displacement.
"covering plates 51 and. 81 are removed from fittings 13 and 10 to give access to the control-pipes and parts. while placing them in positionand making connections. The floor bearings are placed in position as the work proceeds, but are not secured until the entire pipe' is erected, the Y-fittings alined, and the pipe plumbed. In case repairs or replacements of control-pipes or their connections are necessary, this may readily be done by removing plates 51 and 81 when the ointsmay be disconnected and the controlpipcs removed and replaced. To test the;
control-pipes and connections, as well as the operation of the nozz1e-valves,'a water bored and packed as before explained, and
In Fi 9 and 10, -I have shown another form 0 holder for the control-pipes and which form may beemployed either with or without the expansion-joints of Fig. 7. In this form I provide a metal ring 91 having a flange 92 which rests on the end of the pipe section entering a fitting 10, the ring 91 fitting closely within the pipe. Secured to ring--91is looped nd 93,.into the loops of which controlgpipes 15 are placed. These loops are intended to hold the pipes in position but allow them, to slip v for balls 95.
masons lengthwise, and with this form of support ,an ordinary screw coupling will be emloyed to join the pipe sections. In this orm, which is suitable for, stand-pipes in buildings of ordinary height, the stuffingbox at boss 53 of control-fitting 13 will allow 'suflicient length-wise movement of the control-pipes due to expansion or contraction, but intall buildingswhere the control-pipes would be "much lon er, I
form of floor plate 'or bearing that may be employed. In these views, 6 is the standpipe and 94 is a metal ring having a race This ring is secured by bolts 96 to a floor plate made in two halves 9.7 and '98. The ball race is covered byplates 99 and 100,- and these plates are secured to ring 94 by screws 101.' The hearing will be secured to the floor by bolts 102, and in addition it may besecured to an angle plate 103 which is secured to plates 97 and 98 by bolts 10%, and which plate 103 is designed to be secured to the wall of the building. The ball bear-.
ing is intended mainly to reduce friction in rotating the pipe.
- In operating the stand-pipe after water supply is established fromeither one or more of the four sources of supply, the first step is to open control-valve '25 by moving the handle to position U, see Fig. 13; this will admit water under piston 38 in the hydraulic-lift and raise the stand-pipe to, or maintain it in, its elevated osition. To adjust the height of the nozz es from the ceilings or floors, as may be nece ary, valve is moved to position S at r moving the pipe up or down, closing all ports of the valveand holding the pipe stationary.
To move the pipe up or down, the handle of valve'25 is moved either to position U or D and when the desired height for the nozzle is reached, the handle is again moved to position S tobring the pipe to a stop. The height of the nozzles from the ceilings or floors. and the direction they are pointing in are indicated by pointer 8. The direction of. the nozzlesv is adjusted by. rotating the stand-pipe by means of'lever 29; the piston 38 acting as'a floating pivot for the pipe. The stand-pipe will begin to fill with water as soon as the supplylines are opened, and water may be discharged from any one or all nozzles by opening control-valves 14. When a control-valve 14 is opened by moving the handleto a vertical position, either up or down, water flows through strainer 58, pipe 15, valve 14, and pipe 15 to piston cylinder v67. The water pressure on the underside of the piston overbalances the pressure on valve disk and the pressure of spring75, and causes the piston to move upward and open the nozzle-valve. To hold prefer to arrange them in sections an provlde the expansion joints.
In Figs. 11 and 12 are shown in detail one' on piston 7 3 and allow valve-disk 65 to close the nozzle-valve, the handle of valve 14 is moved to the horizontal position, opening the drain-port and closing the inletT-port 15 (Fig. 14f. As the water starts to discharge from cylinder 67, spring 75 moves 7 its the piston downward, and as the valve-disk enters the path of the stream of water pass ing through waterway 60,the pressure on the back of the valve-disk drives and holds i i i a It'will be observed that while the movements following the operation of controlit to its seat.
not only strike a certain point with the stream of water, but also to wet or wash down the entire area within thearadius of the water pressure. Thus, for instance, the pipe may be lowered to bring the nozzles to the lowermost position, and then, assuming that any one or'more nozzle-valves are open, the pipe may be caused to rise and at the same time slowlyrotate with the result that the water would first strike near the pipe at 'one side of the floor area and then slowly sweep across the floor'to: the opposite side of the pipe; the pipe is now rotated in the opposite direction causing the stream to sweep back again at a greater distance from,
the pipe, and so on until the entire area is covered.
