TELESCOPIC STAND-PIPE FOR EXTINGUISHING FI RES.

SPECIFICATION forming part of Letters Patent No. 423,663, dated March 18, 1890.

Application filed October 25, 1884. Serial No. 146,482. (No model.)

.To aZZ whom it may concern.-

Be it known that we, FREDERIC W. BROWN, of Troy, Rensselaer county, New York, and THOMAS S. ILES, of Albany, in the county of Albany and State of New York, citizens of the United States, have invented certain,

new and useful Improvements in Telescopic Stand-Pipes for Extinguishing Fires, of which the following is a specification, reference being had therein to the accompanying draw-- lugs.

This invention has relation to certain improvements in telescopic stand-pipes which are employed in connection with any suitable water-supply for the purpose of extinguishing fires; and the invention has among its objects the provision of improved devices for supporting the stand-pipe when in use and for delivering water therefrom in desired directions and at desired angles. o

Other objects and advantages of the invention will appear in the following description, and the novel features thereof will be specifically set forth in the claims.

Referring to the drawings, Figure 1 is a perspective of a stand-pipe constructed in accordance with our invention as it appears when in position for use in the extinguish ment of a fire in a building. Figs. 2 to 5, inclusive, are enlarged details of the lower section and the adjacent parts of the stand-pipe.

Figs. 6 to 8, inclusive, areenlarged details of the discharge pipe and nozzle and devices for directing and controlling the same; and Figs. 9 and 10 are a side and edge view, respectively, of one of the legs of the tripod employed. Figs. 11, 12, and 13 are details and modifications hereinafter described.

Like letters indicate like parts in all the figures.

In this class of inventions the stand-pipe proper consists of a main or lower section A, intermediate sections B, and an upper or terminal section 0, connected together telescopically, so that when water under sufficient head or pressure is introduced into the lower section the upper and intermediate sections are successively carried up by the pressure of the water, so that the stand-pipe can be elongated or elevated at will to any desired height, the upper section being provided with V a discharge-nozzle D, from which the water is discharged onto or into a burning-building to extinguish a fire.

In our invention each of the sections of the stand-pipe consists of a pipe fitted within the 'next lowersection and provided with a pack ing, as B", Fig. 2, which is clamped againsta flange B by means of a packing-ring B which is screw-threaded to the lower end of 6c the pipe. The flange B and packing serve to provide a water-tight joint between two of the sections.

Co-operating with the packing and flange just described is a short cylinderBt screwthreaded into the upper end of the adjacent section, (B or A, as the case may be.) Riveted or bolted to the short section B are three or more straps E, the upper ends of which are angular and project inwardly, as shown at E Between these straps and the section B is arranged a hoop F, the ends of which are projected parallel with each other, as shown at F, Fig. 3, and are embraced by the arms of a bifurcated handle G, said arms being cam or wedge shaped, as shown at G, so that when said handle is vertical, as shown at Fig 2, the projected ends F* of the hoop are separated from each other and the hoop loosely encircles the section, and when said handle is hori- 8o zontal the said ends are compressed toward or against each other and the hoop snugly embraces the section which it encircles and prevents its longitudinal movement in the adjacent section. The function of the handle and hoop is to secure the sections in an elevated position just before they and the next lower section are raised by the pressure of the water, as before described. The handle of each section is forced to a horizontal posi- 'tion, and as each ring and handle reaches the lower section during the process of lowering the stand-pipe its handle is turned to a vertical position, in order that the next section above may be lowered into its adjacent sec-' tion below, so that when the apparatus is completely lowered and ready for transportation the length thereof is that of the lower sectioni-n addition to the lengths of the successive straps of the additional sections. We do not herein claim theseclamping-rings and their adjacent devices, as they, in connection with other features herein, are ,made the subject-matter of a previous patent, No, 306,575, grantedOetober 14, 1884, to one of us;

In this instance we have devised novel features of construction in the device by which the stand-pipe is supported and adjusted, as

well as novelfeatures of construction in the discharge-pipe, and in the devices for controlling the same and novel improvements in e cylindrical portion of which is flared outwardly from the cylinder, and the flanged portion 1 ofwhich is concave at its upper surface to agree with or fit the convexity of thecasting H. The casting I is provided with lugs 1 transversely perforated for the pivotal connection of the tripod-legs J, as

hereinafter described. Now, it will be noticed that the upper casting, being fixed to the lower section and resting within the concavity of the lower casting, said section, together with those contained therein, when supported on the tripod, as shown in Fig. 1, is suspended and is capable at its lower end of swinging in all directions, whereby it may be positively inclined, so as to project-the upper sections in any desired direction; or it may be (when said sections are inclosed within the main section) allowed, by the action of gravity alone, to assume a truly vertical position, and this notwithstanding the contour of the ground upon which the tripod stands and notwithstanding thearrangement of the legs of the tripod. .l'Ve consider-this means of supporting a stand-pipe as one of the important novel features of our inventiomand we consider the two castings above described,

1 which serve to' support the stand-pipe, as and define the same to be a bowl-joint, being after the nature of a ball-and-socket joint.

Referring to Figs. 8 and 9, although each of the legs of the tripod may be of any usual construction and in any manner adapted for connection with the casting I, in this instance for strength and cheapness We employ a main portion J of wood, havingacasting J, adapted to embrace the wood at its upper end, provided'with an eye J and adapted to enter between the lugs 1 when abolt, rod, or pivot is passed transversely through all, so as to form a hinge-joint. A ferrule or casting J provided with a spike or point J is secured in any suitable mannerto the lower end of the main portion of the leg. Near the lower end of the wooden portion there is formed a slot J passing therethrongh, in which is an eccentric button J which serves to securely said position by means of the guys.

hold a guy rope or cord J which passes through said slot and is suitably connected to the lower end of the main section. There being a cord J 7 for each of the legs, it will be,

seen that when the section has been adjusted to a desired position it may be retained in the button J and at the side of the main portion of the leg, is secured another eccentric button J which operates in connection with a bracket J to securely hold a guy J, (of which there are three,) that extends from the leg to near the upper end of the upper sec tion, or it may be to an adjacent part of the discharge-pipe, so that by the use of the guys J the stability and firmness of the standpipe when extended are assured. The lower end of .the main section A is provided witha series of valves A, having communication through suitable ports or openings A with the interior of the section. The said valves are screw-threaded, as at A for the reception of the ordinary coupling used upon hose, so that water maybe supplied through said hose either from a hydrant or a steam-pump or fire-engine, or other source of supply.

Above Eyes A are provided for securing the guys J to the lower portion of the main section.

Referring to Figs. 6, 7, and 8,it will be seen that the upper section 0 terminates or is provided with a casting 0, having an annular 'flange or shoulder C -and a cylindrical extencasting, and yet a joint which enablesthe rotation of the cylinder (and of the parts mounted'thereon) within the extension 0 Furthermore, this construction facilitates the assemblage of parts in operative position, as shown, and the separation thereof. Embracing the upper portion of the cylinder K is a horizontal beveled gear L, which is secured rigidly to the cylinderby aset-screw L, or it may be by any other well-known equivalent device. The cylinder K projects slightly above the gear L, and is screw-threaded for the reception of an interiorly screw-threaded cap-piece M. The cap-piece is centrally and longitudinally bored to agree with the internal bore of the cylinder K, and is transversely bored, as at M, in tapering form, to receive the discharge- Over this ICC pipe N, which is finished exteriorly to fit the tion of the discharge-pipe, after "passing through the cap-piece, has a quarter-bend,

and to its end is secured in any suitable man-' ner the discharge-nozzle D. The opposite end of the discharge-pipe is provided with a rigidly mounted' belt or rope pulley O, to which is attached a counter-weight O, the function of which is to counterbalance the weight of the discharge-nozzle. The port N is arranged with relation to the quarter-bend of the discharge-pipe, so that when said bend points in a direction opposite that shown in Fig. 8 said port comes in contact with a solid portion M of the cap-piece and the escape of water therefrom is prevented; but when the dischargepipe and nozzle are rotated so as to be in other positions than that mentioned a free passage of water is had through .the port. By con trolling the position of the discharge-nozzle by means of a hand-rope P, passing over the pulley O tot-he ground, the dischargeiof water may be interrupted at will without manipulating the valves A at the base of the stand-pipe, and by the same means-that is,

by the rope P-any desired inclination of the discharge-nozzle can be secured. By the use of a similar rope Q, passing over the pulley O and to the ground, .the gear 0 meshing with the gear L, may be rotated, so as 'to rotate thecap-piece, the discharge-pipe, and'the nozzle, so that said nozzle may be directed to any point in a horizontal plane, and therefore by means of both ropes a stream of water delivered from the discharge-nozzle may be directed to any desired point. e

We do not wishto be understood as limiting our invention to the exact details of con struction herein shown and described, but reserve the right to alter the same in any manner and to any extent within the skill'of persons conversant in the construction of similar apparatuses.

If desired, an additional guy J may be secured to the discharge pipe or nozzle or to the cap-piece or to the upper end of the upper section in such a position as to resist the 're-' action of the outgoing stream of water, and, as before stated, one of the guys J may be arranged in a position to perform this 'function.

By reference to Figs. 1 and 11, an additional device for holding the main section steady and firm will be seennamely, the steadying pin or stake R, which is fitted in the plug or .ton-head.

head of the section, so as to be capable of longitudinal movement after the manner of a piston-rod and is provided with a head R I serving the function of and similar to a pic'- Between the head R and the plug and encircling the stake is a coiled spring R which serves to normally hold the stake with its point or outer end in close WVhen the lower section has, by gravity or otherwise, been brought to a desired position, the admission of water therein acts by pressure upon the head R to forcethe pin outwardly against the tension of the spring until its point come's in contact with 'orpenetrates the ground and is held inthat position so long as asupply of water. is maintained in'the pipe.

As heretofore stated, we do not claim in this application the specific construction of the clamping-rings F; but we illustrate a difsection is screw-threaded or in" some "other well-known manner connected with the casting, said casting being provided with lugs S, arranged diametrically opposite each other. The. clamping-ring F is formed in two sections, each semicircular and provided with projectingendsjadapted to be clamped and bound by the hand-lever G, the pin or bolt S being passed through the bifurcated arms of the handle, through the ends of the semicirculair straps, and through the lugs S, to bind the parts together, when by manipulatingthe handle, as before described, the semicircular straps are 'made to bind upon a section working telescopically in the casting S and the section to which it is attached.
