justed in the form of a screen at the point of the blaze; to provide a fire extinguisher having a hose connection of which the free end is provided with a coupling for connection with the valve of a pneumatic tire,

so that the air under pressure in that may be used as the ejecting medium for the contents of the extinguisher; to provide an extinguisher including a control means for 15 controlling the entrance of air into the container as well as the fluid outlet of the latter; and to provide a device of this nature which is of simple form and therefore susceptible of cheap manufacture.

With this object in view, the invention consists in a construction and combination of parts of which a preferred embodiment is illustrated in the accompanying drawings but to which embodiment the invention is 25 not to be restricted. The right is reserved to make such changes or alterations as practical use may dictate insofar as such changes or alterations may be comprehended in spirit by the annexed claim.

In the drawings:

Figure 1 is a perspective view of a motor vehicle, showing the invention applied in operative position.

Figure 2 is an elevational view of the 35 extinguisher per se.

Figure 3 is a sectional view on the plane indicated by the line 83 of Figure 2.

Figure 4c is an elevational view of the cover member for the container showing the valve in open position.

Figure 5 is an elevational view of the structure of Figure 4 looking from the direction 90 degrees from that in which said Figure at is viewed.

Figure 6 is a top plan View.

Figure 7 is a bottom plan view.

The invention comprises a container 10 provided with lower and upper heads 11 and 12, the former of which is depressed at the center to provide a filling opening which is closed byaremovable plug 1 which, when attached, is above the plane of the bottom of the head 11, so that the latter may set flat on a running board or any plane sur- 3 face. I

The head '12 is formed with a central upstanding Valve body 15. formed with an air intakeduct 16 and a discharge duct 17, the

latter having a lateral outlet passage 18. A I

valve plug19 is mounted on the valve body transversely of the latter, so that in one position, it obstructs both the ducts 16 and 17, whereas in another position at right angles tothe first, it disposes the openings 20 and '21' in registration with the ducts, so thatthere-may be the passage of air down through the duct 19 to' impose pressure on the liquid contents of the tank 10 and force the latter up through the tubular leg mem ber 22 hung from the head 12 in continuation of the duct 17. The leg terminates short of the filling opening in the head 11.

Angular or turning movement is imparted to the valve plug by means of a handle 28 formed from flat stock and so mounted on the plug that it is disposed at right angles to the axes of the holes of the openings 19.

and 20. Thus when the plug is turned to shut ofl' communication between the ducts 16.

and 17, the handle is disposed over the end of the outlet duct or opening 18.

The device is adapted for actuation by air under pressure derived from any acceptable source and to this end a hose 24 has one end coupled to the valve body 15 at the upper end of the duct 16, the other end of the hose being provided with a coupling member 25 designed for attachment to the valve of a vehicle tire, so that its trip pin 26 may unseat the valve in the tire to permit the diccharge of air therefrom which will then pass through the hose 24 and into the ducts 16, through which it will pass to the interior of the tank 10 above the fluid contents of the latter,.if the valve plug be in open position. The pressure of the air will result in forcing the fluid up through the leg 22 into the duct 17 and thence through the discharge outlet 18 by means of which it may be directedonto the fire.

While the hose 24 is provided with a coupling member primarily adapted for connection to a tire, the coupling may be of any conventional form, so that any source of air under pressure may be employed, such as the storage tank of an air pressure system,

'or any other source of pneumaticpressure. U 1. ,c

The invention having been described, what is claimed as new and useful is: v

' A fire extlnguisher comprising a tank having a head formed 'withia valve" casing thereon provided with parallel ducts, a valve plug mounted for angular movement-inthe i Valve casing to establish or out o fi' communi-v cation through said ducts, a'tubularclegde pending from the: head of the tank in con tinuation of one of the ducts an air hose connected to the valve casing at the outer V- end of the other duct, the outlet end of that -V v duct from which the tube extends being above the plane of the axis of the valve H plug and opening laterally on said head, and

an actuating handle securedto the,valve plug and extendingin a-direction at right i angles to the holes through the 'la'tterQthe head having a fiat face against which said handle bears, so that the handle is moved into duct closing position when it is actuated to shift the lug into a corresponding position with reierence to the two ducts.

In testimony whereof I aflix my signature.
