FIRE-EXTENGUISHER.
SPECIFICATION forming part of Letters Patent No. 514,534, dated February 13, 1894.
Application filed August 19, 1893. Serial No. 483,497- (No model.)
To aZZ whom it may concern.-
Be it known that we, ORLANDO W. ALDRICH and SOLOMON M. HALL, citizens of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvementsin Fire- Extinguishers; and we do hereby declare the following to be afull, clear, and exact descrip- -tion of the invention, such as will enable othperienced with apparatus of this kind consists in the settling of large quantities of solids upon the bottom of the vessel which chokes the outlet to the pump and greatly interferes with or wholly obstructing the operation of that instrument. A feature of our invention, therefore, consists in the provision of means whereby the contents of the vessel (and especially such solids as may have settled at the bottom thereof) may be agitated and dis lodged, thereby permitting a free flow of the solution to the pump. When the substances employed in the extinguishing solution are of a corrosive nature, it is important that they be kept from contact with the parts of the pump as much as possible; and our invention includes the provision of devices whereby the pump may be readily and conveniently disconnected for cleaning the same after use without losing or exposing the contents of the reservoir.
The several features of our improvements are illustrated in the accompanying drawings in which- Figure 1 is a sectional view of an apparatus embodying our improvements having a single pump. Fig. 2 is a sectional view of a screw-threaded collar for connecting the upper end of the pump to the agitator pipe.
The vessel or reservoir 1 maybe of any form but the ordinary cylindrical or barrel form is preferred; and its upper end, instead of being provided with a large removable cover as usual, will be tightly closed except at the middle Where there is a small opening 2 through which water and the extinguishing compound may be supplied. This small opening will be closed by a screw cap 3 having asuitable air or gastight packing. The pump 4: which is placed on the outside of the vessel is screwthreaded at its lower end so as to turn into and be connected with the projecting end of the strainer pipe 7. The upper end of the pump has two short outlet pipes 5 and 6 to one of which is connected the hose pipe 9 while the other is connected, by means hereinatter described, to a pipe 10 that extends through the top to the bottom of the vessel. The means for connecting the pump with the pipe 10 consists of a screw-threaded collar 15, as shown, so that when said collar is turned up on the pipe 10 it is turned off the outlet pipe 6. The collar 15 will preferably contain a stop-cock 13. The strainer pipe 7 preferably extends entirely across the bottom of the vessel and is secured tightly in opposite sides thereof so as to afford a more firm support for the pump. The lower end of the pipe 10 terminates in a nozzle 11 which is so arranged as to throw a stream onto the strainer or onto the bottom of the vessel when liquid is forced down through said pipe and thus quickly and thoroughly dislodge and agitate substances that may have settled there.
A stop-cock 12 is provided in the hose pipe or in the short pipe 5 and when this is closed and the stop cook 13 opened the solution may be pumped out of the vessel and back again through the agitator pipe.
To remove the pump for the purpose of cleaning it of corrosive or obstructing substances it is only necessary to close the cook 14 on the outer projecting part of the strainer pipe, turn the collar 15 oft the pipe 6 and unscrew the lower end of the pump. The cook 14 should be kept closed except when it is desired to agitate the contents of the vessel or to use the apparatus in case of tire,
If two or more pumps are employed on one vessel they will preferably be connected with the same strainer and the agitator pipes may terminate in the-same nozzle or outlet.
hen the apparatus is large and designed for public or extensive use the vessel may be supported upon a wheeled carriage of any suitable construction.
To use the apparatus ata fireit is only necessary to close the cook 13, open the cocks l2 and 14c and take off the screw cap 3 when the pump or pumps may be worked as usual.
Among the numerous advantages of our apparatus are: first,it is simple and inexpensive in construction; second, it is very d urahle; third, no special knowledge or skill is required to operate it and keep it in readiness for use.
\Vhat we claim, and desire to secure by Letters Patent, is p 1. In combination with a vessel adapted to contain a fire extinguishing liquid, of apuinp arranged on the outside thereof havingits inlet end communicating with the interior of the vessel and having two outlets, one cornmunicating with the interior of the vessel near its bottom, and the other adapted to be connected with a hose, the said outlets being provided with stop cocks, substantially as described,
2. In combination with a vessel adapted to contain a tire extinguishing liquid, a projecting inlet for said vessel screw-threaded at its end, a stop cock 14 in said inlet, an agitator pipe projecting through and rigidly connected with the vessel and having its end screwthreaded, a stop cook 13 for said pipe, a pump cylinder screw-threaded at its lower end so as to be detachably connected with the screwthreaded outlet pipe and having a screw threaded outlet at its upper end, anda collar 15 threaded to engage the threads of the outlet at the upper end of the pump and those of the agitator pipe so that the said outlet and agitator pipe may be detachably joined, whereby the pump may be readily removed from the vessel without disturbing the agitator pipe, substantially as described.
In testimony whereof we affix our signatures in presence of two witnesses.
