CHEMICAL FIRE-ENGINE.

SPECIFICATION forming part of LetterslPatent No. 432,778, dated July 22, 1890.

Application filed April 1, 1890;

To all whom, it may concern.-

Be it known that I, RANDALL T. VAN VAL-j KENBURG, a citizen of the United States, re-, siding at Muskegon, in the county of Muske-f gon and State of Michigan, have invented cer-, tain new and useful Improvements in Chem-l ical Fire-Engines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to new and useful improvements in chemical fireengines; and the invention consists in the construction, arrangement, and operation of different parts, all as more fully hereinafter described and shown, and specifically pointed out in the claims.

In the accompanying drawings, which form a part of this specification, Figure 1 is a side elevation of a complete chemical fire-engine embodying the various improvements herein described. Fig. 2 is an enlarged rear elevatian of the same, partly in section. Fig. 3 is a detached plan of the half-globular bottles contained in the separate receptacle. Fig. t is a detached vertical section through the half'globular bottles, showing also the seal for closing the mouth thereof. Fig. 5 is a detached plan of the generators and their connections. Fig. 6 is a cross-section of one of the generators. Fig. 7 is a vertical central section through the dry-compound receptacle. Fig. 8 is a horizontal section of'Fig. 7.

The body of the carriage consists of a strong metal skeleton frame arched in the center to permit the front wheel to run under in turning. Its front end is pivotally sup ported on a spring platformgear upon the axle of the front wheels, and its rear end rests upon, side springs on the axle of the hind wheels. The rear axle is dropped between the wheels to form snfficient room for two generators AA,which are of cylindrical form, and are supported side by side above the rear axle by metal straps secured to the frame. Each generator is connected by a valve-controlled connection B with the bottom of the mixing tub or cylinder C, which is supported above the generator on curved bearings D, formed upon the sides of the frame. The mixingcylinder is provided with a fill-opening E in its top, and contains a stirring device (not Serial No. 346,231. (in; model.)

shown) actuated from the outside by the handle F. "In the mixing-cylinder the charges areprep'ared for the generatorsthat is, the solid chemicals are dissolved in a proper amount of waterall as described and shown in a former patent granted to me October, 188$), No. 413,837.

Each generator issurmounted by a globular receptacle b the upper half of which is detachably secured to the lower half, preferably by a hinge II and one or more connectin g-bolts I, which pass throughannular flanges I on the respective halves. The flanges I are adapted to form a tight joint when the receptacle is closed and contain bearings for the trunnions of a globular vessel containing the acid charge. This vessel is preferably composed of two half-globular bottles J,which are tied together by a band J, secured in an annular groove formed by two complementary half-circular grooves in the globular sides of the bottles. Two trunnions J are formed on or secured to the band J, and one of the trunnions projects through the bearing of said trunnion and is adapted to receive a handle J by means of which the vessel may be turned upside down to discharge its contents through the neck J into the generator.

Each of the half-globular bottles has a corresponding half circular mouth J which, when the bottles are banded together, complement each other to form a ring with two halfcircular apertures. A cap K, swiveled to the lower end of a screw L, which passes through the top of the globular receptacle, is adapted to seal the mouths of the bottles. A handle or wheel L on the upper end of the screw serves to turn the screw up or down, and a rubber gasket in the under side of the cap insures a tight joint when the cap is forced down by the screw.

WVithin each generator is secured a perforated shelf Y, so arranged as to receive upon it the contents of the bottles J when they are emptied and distribute it into the solution in the generator. This shelf is preferablytroughshaped in cross-section, and extends longitudinally from one end of the generator to the other, or nearly so, with a suitable incline to accelerate the distribution.

Each generator is provided with a valvebetween the generators and formsa support for the reel. The discharge-pipe M from the generators enters near its bottom and extends to near its top, where it discharges into the receptacle, and another discharge pipe P starts from near the bottom of the receptacle and passes out through the top thereof and connects with the three-way valve Q, by which the discharge may be directed to either one of the two reels 1%,01' to both simultaneously, if desired. These two reels are journaled in line with each other transversely to the frame above the generators, their shafts being supported on their outer ends in bracketsR, secured upon the side frames, and on their inner ends in stuffing-boxes R", which are coupled to the opposite sides of the three-way valve, which latter is supported by its connection with the receptacle l. Both reels communicate through hollow journals with the threeway valve, and the flexible pipes R wound on the reels, communicate with the hollow journals through hollow connections R to which the inner ends of the flexible pipes are permanently secured.

The generators are provided with suitable pressure-gages S and waste-cocks T, and the carriage is provided with a box-seat U, in which a supply of chemicals may be stored for recharging the generators. At the rear end of the carriage there are secured so-called torches V for use at night, and a foot-step W is provided for the convenience of the operator.

The generators being charged with the proper chemicals in the solution and with the acidcontaining bottles incloscd in the separate receptacles or domes provided therefor, the engine is ready for instant use. The charging of an alkaline saltinto the receptacle provided therefor in the discharge-pipe, while not absolutely necessary, has the advantage of preventing the discharge of any acid substance from the engine which may cause damage,

' and if a carbonate is used it will also help to sustain the pressure toward the end of the H liable to appear.

discharge, at which time the free acid is most This receptacle for dry chemicals also regulates the stream by reasonof its ample size and the manner in which the stream passes through.

To use the engine, the operator lifts the stopper off the bottles and pours the contents into the generator by inverting the bottles with the handle on the outside. The contents fall'first -on the shelf, which mixes and distributes them into the solution of the generator. The mixing of the contents of the two bottles is of importance Where the two bottles have different ingredients designed to act chemically upon each other-as, for instance, in using a sulphite for generating sulphurous acid by bringing it in contact with'sulphuric acid contained in one of the bottles. The valves in the discharge-pipes M control the discharge from either generator into the receptacle N and from there it maybe directed by the valve Q to either or both reels. The generators are thus adapted to work independently of each other or jointly, and the stream maybe discharged through either or both reels, as circumstances may require.

Byusing the mixing-tub to keep a-qu-autity of the solution in readiness for a new charge and working the generators alternately one generator may be charged while the other is discharged, and thus great efficiency of the engine is obtained.

The use of two bottles united together permits the use of different chemicals without additional complication in the. mechanism and in the work of charging, while the globular form presents at the same time the maxim unt contents in the most compact form. The time required for charging the generators is also much shortened by the construction and arrangement of the acid-receptacle and the devices forsealing and operating the bottles.

WVhat I claim as my invention is 1. In a chemical fireengine, the combination of two hose-reels journaled inline with each other and provided with hollow journals at their inner ends communicating with the hose upon the reels, a three-way valve cornmunicating with the generator or. generators and with either or both of the reels through bearings formed at opposite sides of said valve and into which the hollow journals of the reels engage, substantially as described.
