GELLAR-PIPE FOR EXTINGUISHING FIRES.

SPECIFICATION forming part of Letters Patent No. 691,858, dated January 28, 1902. Application led December 15, 1900. Serial No. 40,025. (No model.)

To all whom it may concerny Be it known that I, MILTON H. HART, a citizen of the United States of America, residing in the borough of Brooklyn, city and State of New York, have invented certain new and useful Improvements in Cellar-Pipes for Extinguishing Fires, of which the following is a specification. f

My improvement relates to pipes which are let down into cellars from a door above to supply a current of water under control from the said oor for extinguishing aire.

I will describe a cellar-pipe embodying my improvement and then point out the novel features in the claims. l

Figure l is an elevation of a cellar-pipe embodying my improvement, and a sectional view of a door above the cellar is also included in this figure. Fig. 2 shows the cellar-pipe, on a smaller scale, folded for transportation. Fig. 3 is a vertical section of a portion ofthe cellar-pipe on a larger scale than the other igures. Fig. 4 is a vertical section on Vthe same scale as Fig. 3 and of the lower portion of the cellar-pipe.

Similar letters of reference designate corresponding parts'in all thel figures.

The cellar-pipecomprises two sections A" A2, which are connected, by. means of a hinge a', so-that they may be folded close together, as illustratedin Fig. 2, andl securedrin that relation by means of a strap-CL2. The hinge a is connected with an elbow A2 and with'a collar a2, surrounding the adjacent end of the section A. A catch CL4, connected bya hinge a5 to the elbow A2, enga-ges with a flange with which the collar a3 is provided at a point opposite the hinge at' to secure the section A' of the pipe in proper relation with the elbow A2 to conduct the water thereto.

The section A is provided with feet or rests a6, which may be of any suitable form to rest upon the floor B above the cellar. It has also affixed to its under side a ring a7 for recei ving a rod C,'u`p on whicha fireman may stand so as to hold the section A of the pipe in position upon the door B. -This rod C may be withdrawn `from the ring a7 and inserted at one end into a recess formed in that one of the feet a. which is near the outlet end of the section A' of the pipe and inserted at the other end in that one of the feet aG which is near the inlet end of said lsection A. To pervmit'of this, the first-mentioned foot 0.6 is provided internally with a helical spring c' and a disk c2.

A hose is con nected by any suitable coupling as with the sectionA of the pipe.

The elbow A3 extends into or through a hole b,made in the door B,and from it extends down int-'o the cellar the section A2 ofthe pipe. To provide for rotating the section A2, it is connected with the elbow by a roller-bearing. As here shown, the section A2 of the pipe has screwed intoits upper end aring a2, having shown, is madev conical opposite said flange ln the ring a2 are a number ofV holes cl2,

al. arranged in thev same horizontal plane, and opposite them inthe ring is formed a recess or chamber als. Water owing through the elbow A3 may to some extent escape and will be dedected outward by the flange al@ in a lm or spray. The ring a isprovided near i'tsupper end with a flange 0.14, which fits in arecess formed in' the lower portion of the elbow A3, suitable packing a being employed to make a tight joint. Above this flange the ring aurmay be provided with a rim am, and whenY this construction is adopted a bearing will be provided for it in the elbow A3. The lower end of the elbow A3 has a ring all screwed into it, and between this ring 0.17 and the flange am of the ring alla number ot' rollers inthe shape of balls are placed. Thus a roller-bearing is provided for facilitating the rotation oi" the section A2 of the pipe independently of the elbow A2.

A rod A4 extends through a stuffing-box als, I

formed in the elbow A2. It is capable of rotating and also of moving longitudinally. For the purpose of limiting its upward movement it is provided with a collar 0.12, which will coact with a shoulder d20, formed in the neck, which is furnished with the stuffingbox ctls t0 limit the upward movement of the rod A4. Below the collar al" the rOdA4 is made to interlock with the hub of a spider 121, (here shown as formed integral with the ring @11,)so that by rotating the rod the ring IOO a, and consequently the section A2 of the pipe, may be rotated. The lower end ot' the rod A4 is pivotally connected by a pin 0.22 with a rod A5, which extends downwardly through the section A2 of the pipe. At its lower end the section Azof the pipe is provided with a cap A, communicating with a nozzle A7. This nozzle is shown as circular in form and is provided with a central longitudinal diaphragm or partition w23. At its inner end it is screwed into a hollow cylindrical piece @24, that tits within a corresponding recess formed in the cap A6. Thus provision is afforded for tilting or rocking the nozzle up and down. The cylindrical piece L24 is provided with a spider c25, having a rod (L26 rigidly aiiixed to it. A pin or screw ai" pivotally connects the inner end of this rod (L26 with the inner end of the rod A5. The upper end of the rod A4 is provided with a handle t28 and has also combined with it a swing-arm a2, which is connected to it by a pivot e30, and provided with a clip cd1, which will embrace the rod A4 when the swing-arm is in its uppermost position.

By means of the combination of parts which I have described the section A2 of thepipe while extended into a cellar may be rotated from the fioor above by manipulating the handles (t28 and the swing-arm (L29. Additionally the nozzle A7 may be tilted or rocked upwardly and downwardly by pulling up or pushing down the rod Al. Thus great facility will be aorded for directinga stream of water into any portion of the cellar. The operator of this cellar-pipe will be protected by the film of water escaping over the iiange am at the upper end of the section A ot' the pipe.

What I claim as new, and desire to secure by Letters Patent, is-

l. In a cellar-pipe for extinguishing fires, the combination oi' two sections connected by means of a hinge and catch so that the two may occupy substantially parallel positions for transportation or positions at an angle for use.

2. In a cellar-pipe for extinguishing fires, the combination ol' feet or rests provided with sockets or seats for supporting the cellar-pipe, a foot-rod detachably connected to the cellarpipe and adapted to fit in said sockets or seats.

3. In a cellar-pipe for extinguishing fires the combination of feet or rests provided with sockets or seats for supporting the cellar-pipe, a foot-rod detachably connected to the cellarpipe and adapted to tit in said sockets or seats, one of said seats being provided with a spring-actuated disk or bearing.

4. In a cellar-pipe for extinguishing fires, the combination with a section adapted to extend into a cellar, of a discharge-nozzle at the end thereof and of means for discharging water close to the top 'of the said section.

5. In a cellar-pipe for extinguishing fires, the combination with a section Vadapted to extend into a cellar of means comprising a de- Iiecting-[iange such as al@ for discharging water close to the top of the said section.

6. In a cellar-pipe for extinguishing res, the combination ot' a rotatable section for extending into the cellar with a rod interlocked therewith and inside of the sam e, and extending upwardly wholly beyond the cellar-pipe so that it may be manipulated from above.

7. In a cellar-pipe for extinguishing fires, the combination ofa section adapted to extend into a cellar, a nozzle fitted thereto so as to be capable of swinging up and down, and a rod passing through the said section of the cellar-pipe and connected with the said nozzle, and passing out of the cellar-pipe where it may be moved longitudinally from above to swing the nozzle.

8. In a cellar-pipe for extinguishing fires, the combination of a section adapted to extend into a cellar and capable of being rotated in a complete circle, means for rotating it, a nozzle fitted to said section so as to be capable of swinging up and down, and a rod passing through the said section ot' the cellar-pipe and connected with said nozzle and passing out of the cellar-pipe where itmay be moved longitudinally from above to swing the nozzle.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

MILTON I-I. HART.
