CHEMICAL HAND FIRE-EXTINGUISHER.

annorrroarrorr forming part or Letters Patent No. 317,152. dated May 5,1885.

Application filed March 9,1885. (No model.)

To aZZ whom it may concern..-

Be it known that I, EUGENE H. LEwrs, a

citizen of the United States, residing at Ohioago, county of Cook, and State of Illinois,

have invented certain new and useful Improve ments in'Hand Fire-Extinguishers, of which the following is a specification.

My invention, which is an improvement upon the one described in my patent of N ovemher 4, 1884, relates to hand fire-extinguishers with which a liquid charged with gases for extinguishing fire is employed.

My invention consists of a cylindrical tube or case, made of tin or other suitable material, provided near the end out of which the liquid is discharged with a partition,which has area sufficient to prevent the liquid from being spilled out of the .tube by any sudden movement in removing the stopper, but which has apertures enough to permit the liquid in sufficient quantities to be thrown upon a fire to extinguish it. The stopper is fastened or soldered firmly enough to the tube or case to sustain the weight thereof and its contents, but not so firmly but that a sudden pull or jerk will easily remove it. p A Wire loop is attached to the stopper, by which the tube and its contents are suspended from a staple or strong nail driven into the wall. The tube or case is preferably about twenty inches long and two inches in diameter. When required to be used, the lower portion of the tube is grasped by the hand, and is given a quick downward movement or jerk, when the stopper is readily removed.

In the accompanying drawings, Figure 1 is a perspective view of a hand fire-extinguisher embodying my improvements. Fig. 2 is a perspective view of the tube, showing the manner in which it is held suspended by a staple driven into the wall. Fig. 3 is a vertical section of the tube, showing the position of the partition, which is of polygonal shape, and the manner in which the wire loop is at- 5 tached to the stopper. Fig. dis a top view of the polygonal partition, showing the apertures around the same; and Fig. 5 is a perspective view of the stopper and wire loop, showing the preferable manner of its attachment to the 50 under side of the same.

Similar letters refer the drawings.

to similar parts in all A represents the tube, which I prefer to make of tin,and of the size hereinbefore stated.

D is the polygonal partition or diaphragm,

which serves to prevent the liquid from getting out of the tube-in too large quantities,and to distribute the contents of the tube over a much larger surface. The apertures a a at around the same permit the liquid in suitable quan 6o surface; but the loop may be fastened in any.

otherconvenient and sufficient manner. When required to be used, and the tube A is grasped by the hand and given a quick downward 7o movement, the apertures a a a cause it to give or wrinkle, thus breaking the solder around the stopper B and causing it to be easily removed.

The stopper B is made of tin, or any other suitable material which will prevent the es h cape of the liquid, and is secured tightly enough to the tube A by being soldered to support the weight of the tube and its contents, and, as above stated, it is provided with a wire loop, 0, by means of which the extinguisher is suspended from a staple, E, till required for use. When so required, the lower end of the extinguisher is grasped by the hand and by a quick movement or jerk is drawn from the stopper B, leaving it suspended from the staple E by the wire loop 0. The contents of the tube are sprinkled or showered on the fire, the action being kept up with vigor,

and any number of tubes used that may be re- 0 quired to entirely extinguish it.

This hand-extinguisher is designed for smaller or incipient fires. The liquid used is such that by its contact with a heat of about 150 Fahrenheit gases are generated which extinguish fire by absorbing the oxygen.

The essential feature of my invention is the making of a hand fire-extinguisher,with which a liquid charged with gases is employed, consisting of a tube closed at both ends and pro- Ico vided with a partition of polygonal shape ;v and it being apparent that such extinguisher maybe used without employing all the special features above mentioned-as, for instance,
