APPARATUS FOR SUPPLYING WATER FOR EXTINGUISHING F|RES.

SPECIFICATION forming part of Letters Patent No. 598,703, dated February 8, 1898 Application filed mile 12, 1897.

To all whom it may concern.-

Be it known that I, ALONZO STOCKBRIDGE GEAR, a citizen of the United States, and a resident of New York city, in the county and State of New York, have invented new and useful Improvements in Apparatus for Supplying Water for Extinguishing Fires, of which the following is a specification.

The present invention relates to an apparatus for receiving, controlling, directing, conveying, and discharging water and other fluids under pressure or by suction, principally for the purpose of extinguishing fire.

The object of the invention is to provide in such an apparatus a chamber or box or casing located beneath the street-surface and having a cover flush with the street-surface, within which chamber or box or casing are located one or more hydrants and water-pipes communicating with a source of water-sup ply, said hydrants extending above the streetsurface.

Theinvention also consists in providing valves for said pipes or hydrants in the box or casing and means for operating said valves, also located in the box or casingand operated from the street-surface without opening the cover of the box or chamber. Besides these objects are others incident to the apparatus, which will be more particularly described hereinafter and embodied in the claims at the end of the specification.

' of Fig. 2.

. tion, showing door thereon.

The invention is fully described in the following specification, of which the accompanying drawings forma part.

Figure 1 is a front elevation of my apparatus, partly in section, taken on line X X Fig. 2 is a side elevation showing the box in section. Fig. 3 is a plan View. Fig. 4- is a detached side view of the parti- Fig. 5 is a sectional view on line y y, Fig. 4. Fig. 6 is an elevation of the gate-valve, partly in section to show the dripping device of same.' Fig. 7 is a sectional View, enlarged, of the cover of the receptacle and jam, showing the position of the babbitting in same, the dotted lines in this figure showing the position of sectional View of the street-sprinkling pipe andcoupling and an end view, both showing the strainer thereon. Fig. 9 is a detached Serial No. 640,445. (No modeL) enlarged view of the buifer for the cover and the supporting-bracket secured to the top plate of the receptacle.

Similar letters refer to similar parts throughout the several views.

Letter A represents the receptacle or box made of any suitable material-of wood pre pared to prevent decay, of iron,concrete,brick, cement, or paper.' This box, as shown in the figures, is provided with a bottom and is so constructed that one portion, B, is placed under the sidewalk and the other portion, 0, placed under the street. The portion B is covered by a metallic plate I), and the portion 0 is covered by the material comprising the box proper. These two portions or compartments are divided 0% by a partition E,

fixed or removable, provided with a passage or opening a, closed by a door F, which can be held thereto by hinges and bolts or by any other suitable means. The jamb of this door is provided with a flexible gasket or may be babbitted, as hereinafter to be mentioned, for the cover, and is made sufficientlywide so that other than a tight-fitting door would close tightly and exclude the air, prevent freezing, and also allow for expansion and contraction, so that it can always be easily opened. The inner compartment Oof the box is internally supported by the posts a c, and the other compartment is also strengthened by the brace b. The pipes and valve within the compartment 0 are prevented from freezing by the 'partitiomand the door in the partition permits a person entering the compartment for repairs and inspection of valves, &c. The top plate of the box is provided with an opening (1 sufficiently large to permit of a man entering and descending by means of a ladder B into the compartment 13 of thebox for inspection or repairing of valves, Ate. This opening 61 from the top plate is closed by a locked by the device shown in my former application, or by any other suitable means, whereby the stem (1 of the locking device will extend through and above the top plate, so as to allow the lock to be manipulated from the outside of the box. The cover is automatically thrown open by the weight 61 To prevent the cover flying open too forcibly upon the hinges, so as to damage them, I use the buffer U, (see Figs. 1 and 9,) consisting of the flexible buffer a, supported on rod a passing through supporting-bracket v. secured to the under side of the top plate. The buffer to is placed on rod between washers and held in place by the nuts u The eye 10 on the rod has fastened to it the chain @0 which is also fastened to the cover. Now when the cover is thrown open by the weight it can only go back as far as the chain and buffer will'retain a sufficient quantity of Babbitt metal. This use of Babbitt metal is accompanied with many advantages over gaskets formerly used. It insures a tight fit of the cover on the jamb, it is less liable to wear and tear, and because of its nature effectually shields out the water from getting between the jamb and cover into the receptacle when closed. I am aware that by forming a groove in the jamb of the cover-and filling same with'Babbitt metal after the manner of the cover 'a similar result will be produced; but I prefer to babbitt the cover, as before described.

The receptacle is drained by the pipe A placed in the bottom and leading therefrom to a sewer or cistern. It is provided with a strainer a and with a check-valve a which prevents an overflow into the box. This drainage-pipe A can be carried horizontally through compartment 0, out through the siding thereof. In that case the check-valve on pipe A will be more easily accessible and repaired.

G represents the inlet or supply pipe, beingabranch from the main or reservoir. (Not shown.) This inlet-pipe enters the compartment 0 at g? or at any other convenient place at or near the bottom. To prevent ,dirt or water entering the hole through which branch pipe entered, I surround the pipe with a collar g placed on the outside of box. This inlet-pipe extends within the box to about the center of the same, at which point it separates into three branches G G G the center branch being the largest, although this order may be changed. This inlet-pipe'is provided with a gate-valve G and the three branches are each provided with gate-valves G all of which are provided with an automatic dripping device, which not only drip the stand-pipes, but also the valves. This dripping device consists of the orifice g leading into the space 9 under the gate G of the February l8, 1897.

valve, (see Fig. 6,) which space is connected to the outlet-tube Q with drip-valve seat, against which rests the upward-closing dripvalve Q32 with a stem 9 acted upon by the gate of the valve. The drip-valve is kept closed by the weighted lever G When the gate-valve is open, the drip-valve is closed by the weight; but when the gate is closed the said gate will force the stem of the drip-valve down and open'the drip-valve and allow the water to drain off. The weight 9 1s adj ustable on the lever, so that it can be set to the force of the water against it, and this weight makes it less liable to get out of order than if a spring were used. v

The three branches areextended from their valves upward on a curve line ('see Fig. 2 within compartment B to the top plate of the same, where they take a straight line up through said plate and through casing H on the top of said box and then above same, I

where they are curved again outward, as shown in Figs. 2 and 3, and each of these branches is provided with a nozzle-cap h of the construction shown in my former application, Serial No. 624,004, filed February 18, 1897, or any other suitable construction.

The stems I of the gate-valves of the three branch pipes extend up through the top plate of box, where they are provided with a suitable head e', made to fit a wrench used only by the fire department. Branching out from the main to which the hydrant stand-pipes G G are connected there are two pipes P R, which extend up through the box, (see Figs. 1, 2, and 3,) where they are provided with covers similar or such as shown and described in my former application, Serial No. 621L,O0t, filed These two pipes PR are respectively the street-sprinkling. pipe P and street-cleaning pipe R, and they are each provided with valves J or stop-cocks, with valvestem K extending likewise through top of box, where they are provided with suitable heads is, made to fit suitable wrenches. The wrenches used by the fire department will not open the valves of the sprinkling or cleaning pipes, or vice versa, each being provided with differentshaped stem-heads and wrenches. This prevents one department tampering with the other. The casing H surrounding the hydrant stand-pipes outside the box is made of iron and suitably ornamented.

The street-sprinkling pipe P is provided with the hose connection P and the streetcleaning pipe R with the gooseneck R, which latter is provided with a faucet or cook. These two supplemental attachments P R are detachable and when detached suitable coverings arev placed over the discharged end of the street cleaning and sprinkling pipes. The covers to these pipes outside the box may be hinged and can be babbitted to make them water-tight and more easily operated in frosty weather."

The object of the supplemental valve G on the inlet-pipe or main branch leading into IIO ' kling the receptacle is to shut off the Water from the main in case the valves or pipes in box need repairing. When the branch leading into the box outside the same has a valve,

which is sometimes the case, then the supplemental valve is dispensed with. The supple- S S are strainers placed over and within the discharge openings of the sprinkling and cleaning pipes P R, (see Fig. 8,) which prevents any hard substancesbeing dropped into the pipes'whene'ver the covers are left .open.. This omission to close the covers might: happen, and if such substances were dropped down the pipes it might do damage to the valves.

The covers to the street cleaning and sprinkling pipes and the stems to the valves and locking-stem protruding through top plate above the same present more or less obstructions on the top plate and in some cases might This is overcome by forming raised ridges t on the surface be considered objectionable.

of said toppla te, (see Figs. 1 to 3, which shield those obstructions, and the groove formed by these ridges will act as gutters to drain the water off the top. r

r The covers to the street cleaning and sprinpipes may be countersunk in the top plate to remove them from being obstructions thereon.

The curve of the stand-pipes can be changed from that shown, in order to throw the casin g H back, which may be desirable in order to use a wrenchof greater leverage for opening the" valves of the stand-pipes.

The door D is provided with handle c1 which is used to raise the cover, when necessary,by han d. G is a supporting-bracket for the stand-pipes to secure them rigidly to the box and hold them in place securely against jarring incident to the working of the fire-engine. The gooseneck R and the hose connection ,P on their respective pipes are joined thereon by threads,but they may be connected by bayonet-joint. f
