4 Claims. (Cl. lee-s1) This invention relates to a fire extinguisher, or II can be opened or closed. Thetube I is the general object of the invention being to proopened-by its valve when the device is held in va vide means whereby the liquid from the tank vertical position with the conical end downward can be discharged between the walls of a buildwhile the tube II is opened by its valve who;

A cylinder it has a Another object or the invention is to provide nozzle forming tube It connected to one end the nozzle with a point with a part sliding on thereof and this tube It terminates in a point a tube leading from the tank so that the tank II with the bore it of the tube ll having a right can be used for forcing the pointed nozzle angular extending outlet end H which passes 10 through a wall. through a side wall oi the tube It adjacent the This invention also consists in certain other point i5. Apiston I8 is threaded on the threaded features or construction and in the combination part I of the tube 5 and is held in adjusted r and arrangement of the several parts to be hereposition by a nut IS, the conical end '8 projecting inaiter fully'described,- illustrated in the accomfrom the piston.

I 55 Having described the invention, what is claimed as new is:

1. A fire extinguisher oi the class described comprising a nozzle having a point at its outer end tor enabling the nozzle to be forced through a well, said nozzle having a discharge port adjacent the point, a cylinder connected with the rear end oi the nozzle, a closure member for the rear end of the cylinder having a hole therein, a piston in the cylinder, a tubular piston rod con nected with the piston and passing through the hole, a tank connected with the rear end of the piston rod and means including valve means for connecting the interior of the tank with the bore of the tubular piston rod, said bore opening out at the front of the piston.

A fire extinguisher oi the class described comprising a cylinder. n tubular nozzle connected to the iront end thereof, the nozzle ending in e point, the bore of the nozzle having an outlet end nee-sing through a side wall of the nozzle adiaeent its pointed end, a closure melnber in the rear end of the cylinder, 2:. piston slidably ar ranged in the cylinder, a tube connected with the piston and slldinglv passing through the closure member, said tube having a projecting part at the piston of conical shape and the nozzle end of the cylinder having a recess therein ior receiving the conical end of the tube, a tank having one and connected with the rear end of the tube and means for connecting the tank with the bore of the tube.

3. A fire extinguisher oi the class described comprising a cylinder, a tubular nozzle connected to the front end thereof, the nozzle ending in 8.

point, the bore of the nozzle having an outlet end passing through a side wall of the nozzle adjacent its pointed end, a closure member in the rear end the cylinder, 9. piston slidably arranged in the cylinder, 2. tube connected with the piston and slidingly passing through the closure member, said tube having a projecting part at the piston of conical shape and the nozzle end of the cylinder having a recess therein for receiving the conical end of the tube, a tank having one end connected with the rear end of the tube and means for connecting the tank with the bore or" the tube, said means including a tube having one end connected with the bore of the first-mentioned tube, branch tubes connecting the second tube with both ends of the tank, and a valve in each short tube.

4. A fire extinguisher of the class described comprising a cylinder, a tubular nozzle connected to the front end thereof, the nomle ending in a noint, the bore 01 the nozzle having an outlet end passing through a side wall of the nozzle adjacent its pointed end, a closure member in the rear end of the cylinder, a piston slidably arranged in the cylinder, a tube connected with the piston and slidingly passing through the closure member, said tube having a projecting part at the piston oi conical shape and the nozzle end or the cylinder having a recess therein for receiving the conical end of the tube, a tank having one end connected with the rear end 01 the tube,,means for connectingvthe tank with 'the boreoi the tube, and a pump-connected with the tank for forcing air into the tank.
