IMPROVED FIRE-EXTINGUISHER.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom. it 'nitty concern:

Be it known that I, Z. BREED, of Weare, in the county of Hillsborough, and State of New Hampshire, have invented a new and useful Improvement in Fire- Extinguishers; and 1 do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention consistsl First, in so constructing and arrangingV a. fire-extinguisher, charged with water and chemicals, that the charge may be ignited, or the chemicals set in chemical action, after the can or vessel has been closed.

Second, in the arrangement for igniting the charge or a fnze or fulxninateconnected therewith, by means of a dart, wire, or other equivalent means., passing through and worked from the outside of the can.

Third, in holding the charge above the water, and in a position to bev dropped into the basket, or upon the support for the charge, while undergoing .the conibnstion or chemical decomposition.

In the accompanying drawings- Figure l is avertical section ofthe cap of a fire-ex tinguisher, with my improved devices attached.

Figure 2 is a bottoni view of the same.

On` the bottom ofthe cap B is placed a charge-holder, A, of suitable size and form, to receive the end of the package containing the charge, and hold the same until it is desired to ignite the package.

A dart, D, passes through the top of the cap, as

seen in Afig. 2, and is provided witha point, d, for penetrating the paper, and igniting the fulminztte by friction. This dart is held in placevby a coiled spring, O. By a gentle pressure or stroke upon the knob ortop of the dart, the latter is thrust down in contact with the charge, rupturing the package, ig'niting the charge or'l'ulminate, and also dropping or pnshing'oif the charge.

lf desired, this dart may be packed, to make the joint with the'cap more secure. The cap itself has a rubber pecking, E.

I do not limit myself to the precise arrangement, as a wire may be pulled, or any other device may be employed for producing either friction or percussion.

Having thus fully described mypinvention,

I claiml. Igniting the charge in a tire-extinguisher after the can or vessel has been closed, substantially as set forth.

2. The dart D, or its equivalent, operated from the outside, yet acting upon the inside of the fire-extinguisher, for igniting the charge or fulminatc, substantially as described.

3. Supporting or holding` the charge by means of the elnngeliolder A, or its equivalent, and dropping the same after the can or vessel is closed, substantially as set forth.

- Z. BREED.
