IMPROVEMENT IN CHEMICAL FIRE-EXTINGUISHERS.

Specification forming part of Letters Patent No. 152.850, dated July 7, 1874; application filed Marrh 14, 1874.

To all 'whom it may concern:

Be it known that we, WIELLINGTON LEE, of the city of New York, in the county and State of New York, and JOHN A. KLEY, of the city Ot' Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Chemical Fire-Extinguishers, of which the following is a full description, reference being had to the accompanying drawin gs, consisting` of four sheets, in which- Figure l is avertical section of the top portion of a cylinder or tank with the parts in position Fig. 2, a cross-section on line x rv of Fig. 1, showing a top view of an acidbottle and its supports; Fig. 3, a side elevation of such upper portion Fig. 4, a top view ot' the same; Fig. 5, a side elevation of the lockin nut; Fig. 6, a cross-section of the saine on linee c of Fig. 5; Fig. 7, a side elevation of the cover or lid detached Fig. 8, a plan view of the same; Fig. 9, a top or plan view ofthe capplate; Fig. l0, a cross-section or" the saine on line y y of Fig. il; Fig. 11, a detail of an acid-bottle, partly in section; Fig. 12, a vertical section ot' an acid-bottle, enlarged; and F ig. 13, a plan view of the same.

The object of our invention is to make the parts necessary for charging the cylinder or tank easily and quickly adjustable, and at the same time hold the parts securely in position, so that the tank can be readily recharged. Our improvements are mainly designed to be used in connection with large tanks mounted upon wheels to be used as tire-engines, but. they are applicable to all sizes oi' generators, cylinders, or tanks. The nature of our invention consists in so hinging and locking the top that it can readily be swung out of position, so as to expose the acid-botttle; in arranging the acid-bottle so that it can be rcmoved from and replaced in a revolving cup or receiver; and in the several devices and combinations hereinafter claimed.

In the drawings, A represents the cover or lid for closing the mouth of the cylinder; B, screw, provided with arms or levers for holding down the cover; C, screw-rod, running through the cover and its attachments, for operating the stopper; I), acid-bottle; E, shaft, carrying and supporting the acid-bottle; F,

crank for turning the bottle; G, arm or projection supporting the inner end of the shaft E; H, nut or locking device, through which the screw B passes, andpresses on the cover A; K, top plate ot the cylinder; L, hinged lid or ring for holding the acid-bottle in the receiver when inverted; M, hand-wheel or crank for operating the stopper-rod C; N, ange, provided with a screwthread, with which the screw-top I engages; O, opening for the supply-pipe; I, opening for the disclnrge-pipe; It, main tank or cylinder; S, lugs on the top plate K for hinging the lid or cap A; T, handle for moving the nut H; U, lugs or projections on the nut H; V, bottlestopper; WV, hole in the top plate; Z, bottlestopper; a, bottlecase or receiver; b, notchlugs in the top-plate K; c, stnfiing-box on the rod C; d, wheel or crank-handle for operating the rod C; e, outer bearing for the shaft E f, springpawl; g, crank-handle of the crank. F h, spring-notches for holding the bottle in the casca; fi, notch lugs or hooks on the top ofthe acid-bottle; j, arms of the stopper-holder; L, iiange on the plate K; Z, band on the stopperlholder for releasing the springnotches 7L,- m, handle of the stopper-holder. The tank It is constructed in any of the or dinaryT forms, and of the usual material. To the top ot' this tank the plate K is attached by solder or otherwise. This plate has a eentral opening, XV, made suiliciently large to permit the passage ot' the acid-bottle, and is provided with lugs b, which have recesses on their inner sides, into which the projections U of the nut H pass. It is also provided with small lugs or projections S, to which the plate A is hinged by means of the projections J, as shown at Fig. 4. The plate A is made to fit the hole YV ot' the plate K, and is provided with a suitable packing to prevent the escape ot' the gas at that point. It is also provided with a vertical tube, A', around which the nuts II and B are placed, and through which 'the rod C passes. This lid or cover is held in place by the nut H, which, when the lid is in pla-ee, is turned so that the projections U will enga-ge with the notches or recesses in the lugs b. Then in this position the screw-lever B is turned down so as to press with force the plate A with a screwthread.

upon the lid A. These parts are then in the position shown at Figs. l and 3. In order to release the lid,the screw-lever B is turned backward, by a half-turn or more, which releases the nut II, which nut can then be turned i'rom its engagement with the lugs b, when the entire cover can be turned back upon the hinge S J. IVe have provideda pin or handle, T, for operating this nut II, but when it is recessed or out out, as shown at Fig. (i, this handle may be omitted. l

When the acid or chemical bottle is placed in the case a, and the top part is turned into position and locked as described, the stopper V is placed in position by means of the screwrod G, which is provided at its junction with This operation closes the bottle, and also aids in keeping it in position. The rod C is provided with a bearing and stufting box at its upper end to prevent the escape of gas at that point. The bottle-case or receiver a is firmly attached to the shaft E, which shaft is provided with a bearing in the projection G at one end, and with a bearing in the tank-case at the other, which bearin g is also provided with a suitable stuffing-box. The outer end of this shat't E is provided with a crank, F g, and also with a spring pawl, f, which locks into the bearing e, and holds the shaft with the case a in a proper position for receiving the acid-bottle, as shown at Fig. l. By releasing the springpawl fthe case a, with its acid-bottle, can be inverted andthe contents of the bottle discharged into the tank It. Before inverting the bottle, however, the stopper V should be run up ont ot' the way by means of the crank M. The bottle shown in Figs. l and l1 is provided with a neck, to which a collar, N is at- When the bottle is placed in the receiver a the lid L is turned down and engages with the collarN ofthe bottle, and also with a spring-catch attached to the case a,

and holds the bottlelso that it will not fall out when the ease is inverted. This bottle 'D is arranged for storage or transportation independently ot' the tank or its receiver a. For this purpose, we make a screw-cap, I, which is provided with a handle, m, and stopper Z. This cap is screwed onto the collar N, as shown at Fig. 11, when the bottle is to be carried or kept ready i" or `nse outside ofthe tank. When it is placed in the tank, the screw-cap I is removed, as shown at Fig. l, when the stopper V takes the place ot' the stopper Z. The bottle D, shown at Fig.- l2, is without a neck. Vhen this form is used the lid L is dispensed with, and one or more additional springcatches, 71 are attached to the case a. The cap [is also changed, and made as shown at the stopper in this form the arms j are placed v under the hooks t', when the stopper Z is screwed down by the handle m, which holds` both the stopper and the cap iirmly in position. The cap l is used both in inserting and withdrawing the bottle from the receiver a.. In the position shown at Fie'. 12, the stopper Z is iirmly secured to the bottle. When it is placed in the cup the handle m is unscrewed, when the armsj will be disengaged, so that the cap can be withdrawn, and when withdrawn the rin-g or band lreleases the springs h which hold the bottle in the case. The cap A is placed in position after the bottle has been placed in the receiver a, and the stopper V is run down to take the place ot' the stopper Z. By this arrangement ot' the bottles a number' of them can be taken with the machine, and one can be readily changed for another; so that, with two tanks, a continuous stream can be maintained, and, by the use of these caps provided withseparate stoppers, the acid-bottles can be easily handled and'used without waste or injury to the clothing.

For large machines it will be advisable to connect the supply and discharge pipes O and F with the tank through the plate K, but for small tanks they may be otherwise located'as desired 5 or the supply-pipe O may be omitted entirely, and the water turned in through the opening \V.

The chemical operation of this apparatus is the saine as any other, and need not, there fore, be described.

NVhat we claim as new is as follows:

l. The hinged or removable cover A, in combination with the nut II and screw B, torsecurely-*covering the opening W, substantially as specilied.

2. The combination of the plate K provided with the lugs b, cap A, the nut II provided with the lugs U and screw B, with the rod G provided with the crank M and the bottlestopper V, substantially as described.

3. The locking-pawl f, bearing e, and shaft F, in combination with shaft E, case a., and locking-stopper V, substantially as and for the purpose set forth.

4. The holder I in combination with the stopper Z, substantially as and for the purposes specified.'
