FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 409,312, dated August 20, 1889. Application tiled November l5, 1888. Serial No. 290,965. (No model.)

To @ZL whom it may concern:

Be it known that I, SAMUEL H. TIMMoNs, of Evansville, in the county of Vanderburgh and State of Indiana, have invented a new and useful Improvement in Fire-Extinguishers, which improvement is fully set forth in the following specification and accompanying drawings, in whichi Figure I is a perspective view of my portable fire-extinguisher, and Fig. II is a top view, enlarged, of the pumping apparatus.

The object of the present invention is to provide a portable fire-extinguisher, and it belongs to that class in which the liquid or fiuid is placed in a reservoir of suitable size to be readily conveyed bya person from place to place.

This invention consists in having a liquidreservoir of any desiredsize convenient to be strapped to the back of a person, having attached thereto, by means of a tube, apumpcylinder provided with suitable handles, by means of which handles the pump may be held in position and manipulated, and leading from the cylinder of the pump are two pipes, which join in a common nozzle. The pump thus constructed and arranged may be handled by the operator, so that the nozzle can readily be directed toward the fire, all of which will now be set forth in detail.

The chemical engines as usually constructed are iilled with a liquid or liquids which evolve carbonio gas, or produce great pressure within the reservoir during the period of use, so that the liquid is ejected owing to the great pressure. Other portable extinguishers are constructed with reservoirs which contain within them pumps for ejecting the fluid. It is obvious, however, that if the reservoir is large and designed to be strapped to the back of the user, a pump in the reservoir could not be used effectively by the operator. It is also apparent that if the reservoir having a pump therein is to be carried in the hand and.V used in that way to eject the fluid, the reservoir would have to be small, and therefore useless, except for incipient fires. In order, therefore, to provide for all these contingencies and construct an apparatus which will not only be convenient to transport from place toA place, but at the same time have sufficient capacity for any ordinary fire and capable of being easily handled, I have devised the herein-described invention.

In the drawings, A is the reservoir, of any suitable size, having in its head a removable cap Il, and on opposite sides straps or loops C C. At its base is attached a fiexible tube D, having a cock E. The pump or ejecting apparatus is composed ,of a cylinder F, having within a piston-head G and a piston-rod II, attached thereto, one end of which projects through one head of the cylinder.

I J represent forked or bifurcated ends of the tube D attached, respectively, to the opposite ends of the cylinder F. Each pipe I .I is provided with a valve K, which opens toward the cylinder F. On the opposite or forward side of the cylinder, at each end, is attached, respectively, the pipes L M, the outer ends of which imite at a common nozzle N. Both of these pipes are provided with valves O,which open from the cylinderF. The solid head or end of the cylinder I has centrally attached thereto an ear Q, and a bar or arm R is hinged to this ear. The rear end of this bar has a handle S, while its forward end is bent vat right angles toward the opposite side, where it is hinged to the forward end of the lever T, which is centrally hinged to the piston-rod H. The rear end of this lever T has also a handle U. The nozzle N rests on the right-angled projection of the bar R. It will thus be seen that as the operator grasps the handles S U and works them in the form of a bellows the lever T hinges on the forward In operation the outward movement of the lever T causes the liquid in the reservoir to be drawn intothe cylinder Ithrough the tube I, while the liquid within the cylinder is at the same time expelled through the tube M and nozzle N. At the same time the action of the piston-head G closes both the valves in the tubes J L. Then the piston-head returns, the liquid is drawn in through tubes J and expelled through tube L, and so on. I/Vhen IOO not in use, the cock E cuts off the fluid from the reservoir A. As it is essential to supply air to the reservoir A when the liquid is bei-ng` ejected, a cockV is placed in the head of the IQSGIVOIF.

I prefer a saline liquid in the reservoir, as that is found to be Very effectual for extinguishing lires, although any suitable liquid compound maybe used. Itis advisable, h owever7 to use such liquid as will retain its chemical form, so it may be always ready, and it should be of such a character as will not readily freeze or become granulated with age.

It is obvious that the pump herein shown may be inodiiied, and instead of having only a single cylinder two or more cylinders may be used, or, instead of a cylinder, bulbs can be employed to act as ejeetors. These and other modications and Changes can be utilized without departing from the spirit of my invention, the essential'features of which are to provide an ej eoting' apparatus so it can be held in the hand and manipulated and the stream or jet directed by the hand at t-he same time, and in eouplingor connecting this ejector with the reservoir by means of a flexible tube, so that its action is practically independent of the reservoir' while in use by the operator. Y

XV hat I claim as new is- In a fire-extinguisher, an ejector composed of a cylinder having a piston-head and a piston-rod proj ecting from one end, said cylinder bein g' hinged at one end to a handle-bar, and a lever centrally hinged to the pistonrod and its forward end hinged to the bar, and suitable flexible tubes from the reservoir having valves7 and the terminating-nozzle, substantially as herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand, this 3d day of October, 1888, in the presence -of witnesses.

SAMUEL II. TIMMONS.
