4 Claims.

The present invention relates to new and useful improvements in ash trays and more particularly to cigarette extinguishing means associated with an ash tray.

An important object of the invention is to provide a cartridge containing a fire extinguishing fluid under pressure and attached to the ash tray and having means for supplying a controlled amount of fluid thereto for extinguishing cigarettes placed in the ash tray.

Another object is to provide means for easily and quickly clamping a replaceable cartridge in connected position with a feed tube leading to the ash tray and puncturing the cartridge ready for discharging its contents.

A further object is to provide a novel cut-off valve for the feed tube controlled by a lever equipped with a cigarette crushing pan.

A still further object is to provide a device of this character of simple and practical construction, which is efficient and reliable in operation, relatively inexpensixe to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a perspective view of the ash tray;

Figure 2 is a central sectional View taken on the line 22 in Fig. 3, in plan of the ash tray and cartridge chamber, the drawer pull being omitted.

Figure 3 is a transverse sectional view taken on a line 33 of Figure 2;

Figure 4 is anenlarged fragmentary central sectional view of the puncturing connector for the cartridge; and

Figure 5 is an enlarged fragmentary sectional view of the pressure equalizing chamber of the cigarette extinguishing means taken along the plane of section line 5-5 of Figure 2.

Referring now to the drawing in detail, Wherein for the purpose of illustration I have disclosed a preferred embodiment of my invention, the numeral 5 designates a substantially rectangular shaped ash tray which may be used as a sliding drawer mounted in the instrument panel 5 of an automobile, or which may be used as a portable ash tray and placed on any suitable article of furniture or other supporting structure.

A partition I is formed in the ash tray to define a chamber 8 having an open back and provided with a top 9. One end of chamber 8 is also provided with a partition I 0 to form a recess II at one corner of the ash tray.

A clamping screw I2 is threaded through partition I0 and has a knurled finger gripping head I3 at its outer end positioned in recess II and a concavo-convex clamping head I4 swivelly connected to the inner end of the screw by a ball and socket I5. Clamping head I4 engages the rear end of a replaceable fire extinguishing cartridge I6 placed in chamber 8 with its puncturable neck I! received with a liquid-tight fit in a cup-like connector I B at one end of a tube I9. The cartridge I6 may contain 00 or any other fluid suitable for use in the arrangement set forth as a fire extinguishing agent. A hollow prong 20 is centrally located in the connector I8 to puncture the end of neck I! of the cartridge and is formed with one or more openings 2| adjacent the pointed end of the prong and a port 22 at the lower side portion of the prong to admit fluid from the punctured cartridge into the prong and thence to the connector for passing through tube I9.

Tube I 9 leads to a pressure equalizing chamber 23 in the ash tray and in which an inlet valve 24 and an outlet valve 25 are mounted. Both valves are of the plunger type and include

valve operators

35 and 31 respectively having portions adapted to be reciprocated vertically in

cylinders

26 and 21, cylinder 26 being connected to tube I9 and provided with a port 28 opened and closed by valve 24 and cylinder 21 is formed with a transverse port 29 opened and closed by valve 25 and alined with a port 30 in one side of chamber 23 to discharge liquid therefrom into the ash tray.

The

valve operators

35 and 31 project upwardly from chamber 23 and are pivoted at their upper ends of a spring biased lever 3I pivoted to partition I by a spring hinge 32 and formed with a cigarette crushing pan 33 at its outer end swingably overlying the ash tray.

In the operation of the device, a cartridge I6 containing a suitable fire extinguishing fiuid under pressure is placed in chamber 8 and its neck inserted in connector I8 and punctured by prong 20. Inlet valve 24 remains closed and outlet valve 25 remains open when lever M is in its raised position. Downward pressure on the lever, as when crushing a cigarette in pan 33, opens valve 24 by aligning slot 28a of the valve operator 35 with conduit I9 and port 28 to admit a supply of liquid to pressure equalizing chamber 23 and closes valve 25. When lever 3| is released, spring hinge 32 raises the lever and closes valve 24 and opens valve 25 to discharge fluid from chamber 23 into the ash tray to extinguish the hot ashes and burning cigarette butts which may be placed therein.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

Although specifically described, the invention is drawn basically to the combination of an ash tray and fire extinguishing cartridge with means for activating the cartridge and since numerous modifications and changes will occur to those skilled in the art after a perusal of the foregoing description taken in conjunction with the accompanying drawings, it is not desired to limit the invention to the exact construction shown and described. But, all suitable modifications may be resorted to which fall within the scope of the appended claims.

Having described my invention, what is claimed as new is:

1. In an ash tray, an upwardly resiliently biased lever having a cigarette snuffing pan at one end and being hinged at the other end to one side of the ash tray and overlying the bottom thereof, a fire extinguishing cartridge containing a fluid under pressure supported by the ash tray, a pressure equalizing chamber mounted on the bottom of the ash tray and underlying said lever, said chamber having inlet and discharge ports therein, a conduit interconnecting said inlet port with said cartridge, inlet and discharge valves having reciprocable portions pivotally suspended from said lever at spaced points therealong and extending into said equalizing chamber for controlling the ingress and egress of fluid through said chamber, said inlet valve being adapted to normally close said inlet port and said discharge valve being adapted to normally open said discharge port, said inlet valve being adapted to open said inlet port upon depression of the pan whereby fluid issues from the discharge port and is directed toward the lighted end of a cigarette in the pan upon release of the pan.

2. In an ash tray, an upwardly resiliently biased lever having a cigarette snufling pan at the end thereof, said lever being swingably attached to and cantilevered over the ash tray, a pressurized fire extinguishing fluid containing cartridge supported by the ash tray, a pressure equalizing chamber mounted on the bottom of the ash tray and underlying said lever, said chamber having inlet and discharge ports therein, a conduit adapted to connect said inlet port with said cartridge, inlet and discharge valves having reciprocable portions pivotally suspended from said lever at spaced points therealong, said valves extending into said chamber adjacent the chamber ports for controlling the passage of fluid through said chamber, whereby depression of said pan closes said discharge port and opens said inlet port and whereby fluid issuing from the discharge port is directed toward the lighted end the lever, a fluid conduit interconnecting said chamber and said cartridge, inlet and discharge valves in said chamber for controlling the passage of fluid therethrough, the upper ends of said valves being disposed exteriorly of said chamber and pivotally secured to said lever at spaced points therealong, whereby depression of said lever opens said inlet valve and closes said -,outlet valve allowing fluid to collect in the chamber, and release of the lever closes said inlet valve and opens said discharge valve to emit a charge of fluid into the ash tray.
