RANDALL T. VAN VALKENBURG, OF MUSKEGON, MICHIGAN, ASSIGNOR TO THE MUSKEGON CHEMICAL FIRE ENGINE COMPANY, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 413,837, dated October 29,1889.

Application filed June 5, 1889. Serial No. 313,221- (No model.)

To all whom it may concern.-

Be it known that I, RANDALL T. VAN VA KENBURG, a citizen of the United States, residing at Muskegon, in the county of Muskegon and State of Michigan, have invented certain new and useful Improvements in Chemical-Engin es, 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-engines, intended to form an improvement on Letters Patent No. 383,303, granted to me May 29, 1888 and the invention consists in the novel construction, arrangement, and combination of different parts, all as more fully hereinafter de scribed, and specifically set forth in the claims.

In the drawings which accompany this specification and form a part thereof, Figure 1 is a side elevation of my improved chemical-engine. Fig. 2 is a plan thereof with the hose-reel removed to show the parts below. Fig. 3 is a rear elevation. Fig. Ais a diagram plan of the mixer, generator, and connections thereof. Fig. 5 is a vertical longitudinal section on line X X in Figs. 2 and 4.. Fig. 6 is a horizontal section on line Y Yin Fig. 3. Fig. 7 is a vertical central section on line Z Z in Fig. 2. Fig. 8 is a horizontal section on line W W in Fig. 3. Fig. 9 is a detached perspectiveview of one of the perforated cups shown in Figs. 7 and 8.

All the operating parts of my chemical-engine are mounted upon" a light and strong frame mounted on two wheels A A on a curved axle B, and a small wheel C (see Fig. 1) in the center in front of the wheels A A serves as a front support. The frame is preferably constructed of the longitudinal bars D, rigidly connected near the front and rear by crossbars E, with the inner longitudinal bars extended in front and provided with a suitable draft appliance, such; as the handle-bar F and the rope-pulley G. The frame is supported on the axle by means of springs, such as the C-springs H under the side bars of the frame and the cross-spring I, which connects the rear ends of the side springs and supports the frame in thecenter of the rear crossbar of the frame. The frame thus constructed forms an opening in the center, in which the generator J is supported, and two openings on the sides, in which the boxes K K are secured, and which serve to carry the materials for charging the generator.

The generator forms a closed tank and is suitably constructed to withstand a high degree of pressure, and for this purpose it is preferably made of cylindrical shape with convex heads, as shown, and is supported upon the frame by means of the lugs a, secured to the sides of the generator. Near the rear end thisgenerator is provided with a dome L, which incloses the acidchamber, and the dome is provided with a removable head L, detachably secured thereto, preferably by means of a screw-thread engagement, suitable hand-holds L being formed on said head for conveniently screwing it on and ofi when required to charge the dome with the acid. Into this dome L is fitted a removable cylindrical vessel M, which is provided with one or more vertical ribs M, which engage into corresponding grooves on the inner face of the dome L, for the purpose of holding the' vessel Min a fixed relation within the dome L and prevent it from rotating therein. On the bottom of this vessel is formed a spider M", which may be formed integral with the ribs M, and which supports on a central step M the breaker-shaft M This breaker-shaft is provided at its lower end with the breakerarms M and passes through a stuffing-box M? in the headof the dome, and bears a handle MTfor rotating it in its bearings. To the walls of the inner vessel are secured the openended pockets N, adapted to securely hold the acid-containing bottles 0. The bottom of the vessel M is perforated or provided with the screen P. v

To the top of the generator are connected two discharge-pipes Q and Q, which are controlled by the valves Q and extend downwardly in front of the generator. They connect into the horizontal system of dischargepipes Q andQ which form two distinct outer circuits around theends and sides of the generator and terminate at the rear end near the center in the coupling members Q and'Q, to which the fire-hose is adapted to be secured. I preferably connect the two systems of discharge-pipes into onesingle structure, which IOC forms a four-sided pipe-frame, supported by brackets b on the four corners upon the cross or the side bars of the supporting-frame. At difierent places in these discharge-pipes, preferably at the corners, and in the center where the two systems are united, I place enlarged couplings S, S, and S The couplings S at the four corners of the frame are preferably cast integral with the brackets I) and are provided with an opening on top, which is closed by a screw-cap c, and in this opening is removably secured a cup T, made of perforated metal or wire screen. In the bottom of this coupling is an opening or drip, which is closed by a suitable drip-plug (Z. The couplings S S are similarly constructed to the couplings S, but are made twice as long and divided in the. center by a partition (2, so as to form a separate chamber for each system of discharge-pipes, and the coupling S is provided in the same manner as described for the couplings S with the screw-cap and perforated cup, and the drip at the bottom of the chamber with the screw-plug. The coupling members Q and Q are connected to or formed integral with the coupling S", as shown. The coupling S is similarly constructed with the coupling S, except that the openings on top of the coupling are connected to the discharge-pipes Q and Q, respectively.

Upon the forward part of the frame is supported the mixing tub or cylinder U. This contains an axial shaft journaled in suitable bearings in the head of the cylinder, and is provided upon one end with the crank U and within the cylinder with the stirringwings U. The top of the cylinder is provided with the opening or hopper U which is closed by a suitable cover U From the bottom of the cylinder a discharge-pipe V leads into the generator, and this pipe is controlled by a valve V, and its inlet-opening is covered by a screen V. This mixing tub or cylinder is secured above the level of the top of the generator, so that its contents may be drained into the generator by opening the valve V. It is preferably inclosed in an outer frame U, by means of which it is supported upon the forward portion of the frame.

A hose-reel IV is suitably supported upon the frame of the machine, and upon it are preferably secured two lines of hose, and from the central support of this hose-reel an arm f extends rearwardly and is provided at its free end with the hinged cap g, which is adapted to engage with the free end of the lever M A pressure-gage Y, Fig. 1, is attached to any suitable part of the generator, and to the under side of the generator is attached the blow-off pipe Z, which is controlled by the blew-off cook or valve Z.

In practice, the parts being constructed and arranged as shown and described, they are intended to operate as follows: A suitable quantity of the carbonate, together with the necessary amount of water for forming a solution, is introduced into the mixing-tub U, and by turning the crank U a quick solution is effected. From there, by opening the valve V, the contents are drained into the generator, after which the valve V is closed. The bottles containing the acid having been preiously secured in the pockets N of the acidcontaining vessel, the lever M of the breaking device is disengaged from the lockinglatch g. Then, by giving it a vigorous turn, the breaker-arms M at the lower end of the breaker-shaft will smash the bottles and allow the liquid to escape through the perforated bottom into the generator, all pieces of broken glass being retained in the vessel M. The generator having now become charged, a discharge may be effected by opening either one of the valves in the dischargepipes Q and Q or by opening both of the valves, as desired. Thus either one or two streams may be obtained from the engine. The discharge through the discharge-pipe Q follows the system of pipes Q to the outlet Q, and the discharge through the discharge-pipe Q follows the system of pipes Q to the outlet Q into the flexible hose connected thereto.

The object of the perforated cups T is to contain some dry carbonate for the purpose of neutralizing all the acid which may possibly be carried 01f from the generator unconsumed, and thereby it not alone increases the pressure, but also prevents the waste of acid and its injurious action in the dischargepassages and hose. If the material in these cups become spent, they may be readily refilled by unscrewing the cap 0.

.The special advantages of my construction consist in the economical disposition of the various parts, in the facility for controlling the generator and obtaining one or two streams, the formation of the circuitous system of discharge, whereby all the acid may be eliminated from the charge, in the peculiar construction of the system of discharge-pipes, which forms an element of strength in the construction, in the novel arrangement of the mixing-tub, whereby no time is wasted in preparing new charges, as a solution maybe readily prepared while the generator is discharging, and in the peculiar arrangement for per mitting the whole system to be drained and cleaned after use.

By bending the axle downwardly, as shown, the generator may be hung low, and thereby present great stability combined with light draft.
