T. E. OONNE'LLY.
CHEMICAL FIRE EXTINGUISHER.
No. 317,513. Patented May 12, 1885.
M ma 7% m UNITED STATES PATENT OFFIC THOMAS E. OONNELLY, ()F PITTSBURG, PENNSYLVANIA, ASSIGNOR OF ONE-HALF TO JOHN S. OONNELLY, OF SAME PLACE.
CHEMICAL FIREEXTINGUISHER.
SPECIFICATION forming part. of Letters Patent No. 317,513, dated May 12 1885.
Application filed September 3, 1883.
To all whom it may concern:
Be it known that I, THonAs E. (JoNNELLY, l
of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Chemical Engines; and I do hereby declare the following to be a full, clear, and exact description thereof.
My invention relates to an improvement in chemical engines or fireextinguishers; and it consists, mainly, in combining with a basket or cage having a cushion-spring for supporting and cushioning a frangible chemical receptacle, a plunger, also provided with a cushioning-spring, whereby the frangible chemical receptacle is effectually guarded against accidental fracture.
I will now describe my invention so that others skilled in the art may manufacture and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a side elevation of my improved chemical engine. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a .side elevation, partlyin section, of the basket detached. Fig. 4is an end view of the plunger-head, and Fig. 5 is a side elevation of the same.
Like letters of reference indicate like parts wherever they occur.
In the drawings, (t represents the body of the engine mounted on a suitable carriage, as shown in Fig. 1.
At thetop of the cylinder at is the mouth b, through which the chemicals are introduced. This month is closed by a removable head or screw-lid, 0, which screws inside of a screwthreaded collar, d.
Extending vertically through a suitable opening in the lid or cover 0 is a plunger or piston, e, at the lower end of which is a head or disk, from the edges of which V-shaped knife-edged lugs or arms cextend laterally.
This rod or plunger is adapted to be moved up and down in the packin g-box f Below the lid 0, inside of the extinguisher, is a removable basket or bucket, h, having a perforated bottom and sides, and a bail, h;
Around the upper edge of the basket h is a ring or collar, 2', which rests on ashoulder, 70, formed on the inner face of the ring or 001- (No model.)
} lar d, while the body of the basket extends down into the extinguisher.
Inside of the basket his a bottle,j, of glas or other frangible material, which contains the acid. This bottle is kept stationary in the basket by means of a spring, I, in the bottom of the basket, and a spring, on, on the face of disk j, which bear on the bottom and top of the neck of the bottle and prevent it from being accidentally broken.
The operation is as follows: The body of the extinguisher is charged in the usual manner; the basket h is then placed in position in the mouth of the extinguisher, the hermetically'sealed bottle j, containing the acid, is placed therein, and the cover 0 is screwed in the ring d. By striking a blow on the top of the plunger 0 the disk f descends and breaks the bottle, the lugs 9 serving to split the bottle longitudinally, so that the entire contents thereof shall escape into the basket, and thence, through the interstices or perforations, into the body of the extinguisher. Vhen the charge has been exhausted, the cover a is unscrewed, the basket-h is removed, and the broken glass is emptied therefrom. The extinguisher is then recharged, the basket is replaced, containing another bottle of acid.
The different parts of the engine may be constructed of any suitable materials. I prefer, however, to form the plunger 0 and basket It of brass, so as to resist the action of the acid.
The advantages of my invention are that the difl'erent parts of the apparatus are easily accessible, and may therefore be prevented from corroding.
The engine is easily charged rapidly without danger of injury to the apparatus or workman, and the bottle or acid-receptacle is protected by the springs from being accidentally broken.
My improved engine may be charged with niacal, nitrous, carbonic-acid, or other gases effective in smothering flames.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, isi any suitable chemicals for generating ammo- In it chemical engine or fire-extinguisher, In testimony whereof I have hereunto set the combination of a basket or perforated my hand this 29th day of August, A. D. 1883. cage having a cushioning-spring arranged in its bottom, a crushing-plunger having a cush- 5 ioning-spring at its lower end, and an inter- Witnesses:
posed frangible chemical receptacle, snbst-an- L tially as and for the purposes specified.
