GEORGE W. HOGLEN, OF DAYTON, OHIO.

FIRE-EXTINCIUISHER.

SPECIFICATION forming part of Letters Patent No. 455,209, dated June 30, 1891. Application filed October 29, 1890. Serial No. 369,706. (No modelll To all whom, it may concern:

Be it known that I, GEORGE W. HOGLEN, a citizen of the United States, residing at Dayton, in the countyof Montgomery and State of Ohio, have invented certain new and usef ul Improvements in Fire-Extinguishers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable .others skilled in the art to which it appertains to make and use the same.

It is the object of my invention to provide ing separate and, when desired, for readily mingling the alkaline and acid elements ordinarily employed in chemical fire extinguishers.

My invention further relates to improved means for preventing the freezing of the liquid contents of the extinguisher.

With such objects in view my invention consists in the parts and combinations thereof hereinafter more particularly described and claimed, Without, however, intending to limit myself to the exact construction which, for the sake of illustration, I have set forth.

In order to make my invention more clearly understood, I have shown in the accompanying drawings means for carrying the same into practical effect.

In said drawings, Figure l is a vertical sectional view of a fire-extinguisher embodying my improvements. Fig. 2 is asectional view, on a larger scale, of the vessel or bottle for containing the acid and the means whereby it is supported, stoppered, and emptied. Fig. 3 is a bottom plan view of the cap or stopper of the extinguisher. Fig. 4 isa sectional view on line 4 4 of Fig. 1.

Referring to the drawings, A indicates a water and gas tight chamber of sufficient strength to bear the necessary pressuresay one hundred or one hundred and fifty pounds-provided at its lower end with a pipe 13, having a delivery-nozzleb and controllingcock I). At its upper end said chamber is provided with a neck A, riveted or soldered thereto, and having at its inner upper end a screw-thread.

0 indicates a correspondingly-screw-threaded cap or stopper having a horizontal flange 0 provided with V-shaped annular grooves b c and with handles 0, by which it may be tightly screwed intoplace.

flange c and the upper end of the neck A and adapted to be forced by the pressure of the cap into the grooves c, and thereby caused to effect a perfect closure of the chamber and also be prevented from being forced outward from beneath the flange. l

The chamber A is adapted to contain an alkaline solution of any usual or preferred character.

The vessel (preferably and ordinarily a bottle) for holding the acid is indicated at E. It is supported by a vertically-movable rod F, passing through the top of the chamber A or through the cap O, preferably the latter, and having at its upper end a handlef, by which it may be readily depressed. The rod 1s normally held in its highest position by a spring G, which bears against the top of the cap and under side of the handle f. Below the cap the rod F is provided with a flange or collar f and between said collar and the cap with a soft or compressible washer f which will be held tightly against the under surface of the cap by the pressure of the spring G, thereby perfectly closing the opening through which the rod passes.

H is a ring, preferably made in the form of a clasp and hinged at h to the lower end of the point where it is hinged to the rod; but in order to adapt it to bottles of slightly-varying size I prefer to divide it also at the side opposite the hinge, providing one end with an ear it, having a smooth bearing, and the other end with an ear k having a screw-threaded aperture. These ears are engaged and adapted to be forcedtogether to clasp firmly a bottle E by a screw h If preferred, the bottles may be provided near their lower ends with a shallowexternal groove adapted to receive the ring or clasp H.

On the under side of the cap 0 is cast 01' soldered anannular depending flange 0 within which is seated an elastic packing I, adapted to close the mouth of the bottle when the latter is held against it firmly by the pressure of the spring G. The outer layer or surface 71 of this packing is noncorrodible, and preferably D is a rubber ring situated between the the rod G. This ring may be divided only at of mineral wool, while I have found a thick soft woolen fabric suitable for the backing 2''. By these means the acid will be kept from spilling during all ordinary motions or shocks to which the extinguisher may be subjected as it is being carried or handled.

When it is desired to use the device, it is simply necessary to strike or to press the rod F by means of the handle f, whereupon the vessel E, being eccentrically supported by the pivot It, will swing downward and become inverted in the position indicated by dotted lines in Fig. 1, thereby discharging its acid contentsinto the alkaline solution. The usual reaction at once takes, place, and the extinguisher is ready for use and will deliver a stream of great force through the nozzle Z).

In order to prevent the freezing of the alkaline solution, I provide the extinguisherchamber A with a non-conducting covering, which will protect it from sudden changes of temperature. According to my i improvements the chamber A is surrounded by a casing J, between which and the chamber is left a considerable space. The outer surface of the chamber and the inner surface of said casing are covered, Fig. at, with alayer of corrugated tar board or paper K, and between these layers the space is filled with wool, felt, or other equivalent material L. The contents of the chamber A are thus most effectually protected, while any moisture or water of condensation forming upon the metal surface will be permitted to pass down the corrugations of the paper and prevented from dampening the felt and causing it to lose its con-conducting character. The bottom J of the casing may be removable, as illustrated, for the purpose of cansing access to the packing. Pinsj, fixed in the casing J, and slots j in the bottom, Fig. 1, serve to securely hold the latter in place. The cap C (shown in Fig. 2) is adapted for an extinguisher having a single Wall, (without a casing J and is consequently of less vertical dimension than that shown in Fig. 1. The

sudden downward impulse communicated to the bottle by striking the handle f will tend to cause the bottle to swing away from the rod F and around the pivot h; but I further insure the prompt inversion of the bottle by a spring M, attached to the rod and pressing against the bottle.

Having thus described my invention, whatI claim, and desire to secure by Letters Patent of the United States, is-

1. In a fire-extinguisher, the combination of a movable rod, a clasp or holder hinged thereto, a vesselsecured in said holder and situated with its center of gravity above the hinge, a stationary stopper for the vessel, and

means for supporting said rod to hold the vessel in place, substantially as set forth.

2. In a fire-extinguisher, the combination of a movable rod, a separable clasp or holder hinged thereto and adapted to receive bottles of varying sizes and provided with the clamping-screw h a vessel secured in said holder and situated with its center of gravity above the hinge, a stationary stopper for the vessel, and means for supporting said rod to hold the vessel in place, substantially as set forth.

3. In a fire-extinguisher, the combination, with the chamber, of one or more reciprocatory rods F, a clamp hinged thereto, a spring for tilting the bottle relative to said rods, and a stationary stopper for the bottle, substantially as set forth.

4. In a fire-extinguisher, the combination of a movable rod, a cap having a bearing therefor, a clasp or holder hinged to said rod and carrying a vessel or bottle, a spring G for supporting the rod, and a packing-valve or washer carried by the rod and adapted to be held by the spring tightly against the under surface of the cap, substantially as set forth.

In testimony whereof I affix my signature in the presence of two witnesses.
