Description

J. M. STCGKING. PORTABLE FIRE EXTINGUISHING APPARATUS.
APPLICATION FILED SEPT. s. 1912..
1,262,865. Patented Apr. 16, 1918.
IHVEI'I far AH-urr/ g JAMES M. STOCKING, OF SIMSBURY, CONNECTICUT.
PORTABLE FIBE-EXTINGUTSI-TING APPARATUS.
Application filed September 5, 1917.
To all whom it may concern Be it known that 1, JAMES M. STOCKING, a citizen of the United States, residing at Simsbury, in the county of Hartford and State of Connecticut, have invented a new and useful Improvement in Portable Fire- Extinguishing Apparatus, of which the following is a specification.
This invention relates to a fire extinguishing apparatus which is more especially designed for the use of fire wardens and forest rangers, although it is very serviceable for persons living in isolated localities not supplied with water pressure available for extinguishing fires.
The object of the invention is to provide a simple, light and cheap portable apparatus for extinguishing fires in isolated localities which is so constructed that the reservoir can be conveniently filled with water when necessary and the water can be forcibly ejected for service.
This apparatus has a small, light and convenient hand operated pump with a fourway cock and connections from the cock to the top and bottom of the pump, a connection from the cock to a flexible reservoir or bag made of water-proofed material and provided with suitable straps so that it can be quickly donned and easily carried on the back of a person, and a connection from the cock to a nozzle which can be utilized for directing the discharge of water or for the suction inlet of water. When the pump is operated and the cock is turned one way water may be sucked from a brook or pool through the nozzle and discharged into the bag for providing the supply of water, and when the cock is turned the other way this water can be forcibly discharged from the bag through the nozzle for service.
Figure 1 of the accompanying drawings shows a side view of the apparatus. Fig. 2 shows a transverse section through the cock. Fig. 3 shows a longitudinal section of the tip of the discharge nozzle. Fig. 4; shows a longitudinal section of the screened base of the nozzle. Fig. 5 is a section showing the valves at the bottom of the pump and lower end of the pump piston.
The pump shown is of a common type having a tubular piston chamber and a globular air chamber 2. The piston 3, which moves up and down in the piston chamber, is connected by a rod 4 with the Specification of Letters "Patent.
Patented Apr. 16, 1918.
Serial No. 189,878.
operating handle 5. In the lower end of the piston is the ball valve 6 and at the bottom of the pump is the ball valve 7.
The four-way cock 8 has a plug 9 that is turned by the handle 10. The upper end of the cock casing is connected by a pipe 11 with the upper end of the pump. The lower end of the cock casing is connected by the pipe 12 with the lower end of the pump. One side of the cock casing is connected by a flexible tube or hose 13 with a reservoir 1%. The reservoir is desirably made of water-proofed canvas or similar flexlble material, 51116118 of such a size as to hold the desired quantity of water; This bag is provided with shoulder straps 15' through which the arms can be quickly thrust so that the bag may be easily carried on the back of a person. The other side of the cock casing is connected by a flexible tube or hose 16 with a nozzle. The nozzle shown consists of a base 17, an intermediate sectionlS and a tip 19, the tip being screwed upon the intermediate section and the inter mediate section being screwed upon the base. The base is provided with a screen 20.
hen the plug of the cock is turned to one position, for instance, as shown in full lines in Fig. 2, and the pump is worked with the nozzle in a brook or pool, water will be sucked into the nozzle and forced by the pump into the bag. To facilitate the flow of water the tip of the nozzle is usually unscrewed so that the entrance opening will be larger. When the plug of the cock is turned to the other position as indicated by dotted lines and the pump is worked, water will be sucked from the bag and forced by the pump out of the nozzle. In this case the tip of the nozzle is in place so as to insure a small stream which can be easily directed for a considerable distance. The screen in the base of the nozzle prevents the entrance into the cock and pump of leaves and ,other debris, and if this screen should become clogged it can be readily cleaned after unscrewing the intermediate section of the nozzle. When the pump is being used the lower end is rested upon the ground and the foot of the user may be placed upon the lower end of the pipe connection to hold it firmly in place while the piston is being reoiprocated. This apparatus which can be carried on the back by any one, can be filled with water for initial use from any convenient brook or pool in the Woods or fields and the Water supply can be replenished when exhausted, the change from filling condition to discharging condition being effected by a mere turn of the cock, making the device particularly serviceable for fire Wardens and forest rangers patrolling for incipient fires.
The invention claimed is:
l. A portable fire extinguishing apparatus comprising a forcepump, a reservoir, a nozzle, a four-Way cook, a connection from the cock to the top of the pump, a connec tion from the cock to the bottom of the pump, a connection from the cock to the reservoir, and a connection from the cock to the nozzle.
2. A portable fire extinguishing apparatus comprising a force pump, a reservoir, a nozzle, a four-Way cock, a rigid connection from the cock to the top of the pump, a
rigid connection from the cock to the bottom of the pump, a flexible connection from the cock to the reservoir, and a flexible connection from the cock to the nozzle.
8. A portable fire extinguishing apparatus comprising a force pump, a Water carrying bag, a nozzle, a four-Way cock, and connections from the cock to the top and bottom of the pump and from the cock to the bag and the nozzle.
4. A portable fire extinguishing apparatus comprising a force pump, a reservoir, a sectional screened nozzle, a four-Way cock, and connections from the cock to the top and bottom of the pump and from the cock tothe reservoir and nozzle.
A portable fire extinguishing appara-- tus comprising a force pump, a pipe connecting the top and bottom of the pump on the exterior thereof, a four-Way cocka-rranged in said. pipe, a Water carrying bag connected Withthe cock, and a nozzle connected With the cock.
