FLAME EXTINGUISHER Application filed March 1, 1933.

This invention relates to improvements in flame extinguishing devices, and while said device is capable for use in extending the flames of lamps, lanterns and the like, it is particularly adapted, as will be hereinafter pointed out, for extinguishing the flames of candles.

I am aware that it has heretofore been proposed to extinguish the flames of candles 0 and lamps by the directing of a blast of air thereon. \Vhile these devices are well adapted to the extinguishing of lamp flames, all such devices with which I am familiar, have disadvantages when employed to extinguish the flame of a candle.

Such devices with which I am familiar discharge but a single stream of air, which if not accurately directed, fails in its purpose, thus necessitating movement of the device until the stream of air is so directed as to impinge upon the flame.

Another disadvantage inherent in those devices which project but a single blast of air is, that when such devices are properly positioned to extinguish the flame, the projected blast of air causes a scattering and splattering of the hot grease which is always present in liquid formed at the base of a candle flame.

It is one object of the present invention to provide a device which employs air to extinguish the flame of a candle, which device will not have those disadvantages heretofore mentioned.

A feature of the invention resides in a novel construction whereby proper positioning of the device relative to a flame to be extinguished is assured.

A further feature of the invention resides in a novel construction whereby a plurality of streams of air are projected into contact with the flame from points circumferentially thereof.

Still a further feature of the invention resides in a novel arrangement of parts whereby the hot grease in its liquid form at the base of the flame will not be splattered by gie blasts of air employed to extinguish the ame.

Serial No. 659,131.

Other features of the invention will become readily apparent as the nature of the invention is better understood, for which purpose reference will be had to the drawing forming a part of this application, and to the following description thereof.

In the drawing, 1

Figure 1 is a perspective view, illustrating the manner of use of a device constructed in accordance with the present invention,

Figure 2 is a view in side elevation, partly broken away,

Figure 3 is a fragmentary top plan View of the flame encircling portiontof the device, Figure 4 is an enlarged fragmentary sectional view illustrating the manner in which the device functions to extinguish a flame,

and; 1

Figure 5 is an enlarged detail longitudinal sectional view. l

A device constructed in accordance with the present invention includes a main body portion 10, a flame encircling member 11, and a handle portion 12.

The main body. portion 10 is of tubular form and in actual practice is produced in different lengths to meet different require ments as to heights.

The flame encircling member 11 is preferably of circular form and is formed as an integral part of the main body portion 10. This flame encircling member is hollow, preferably of tubular form, and is provided in its inner wall with a plurality of air discharge openings 13.

By reference to Figure 4 of the drawing it will be readily apparent that these discharge openings are so arranged that when the flame encircling member is placed in flame encircling position in which it is shown in Figure 4, said openings incline slightly in such a manner that the blasts of air discharged therefrom will be directed upwardly as indicated at 15 in said Figure 4.

This construction has a particular advantags in that a greater latitude of position of the flame extinguishing device relative to the flame, with a certain extinguishing of the flame, is permitted. Furthermore, this construction will never permit of the blasts of air being projected directly upon the hot grease at the base of the flame and consequently the splattering of this grease can never result from an extinguishing operation.

The handle portion 12 is provided with a rubber bulb or similar device 17 through whichthev handle passes as illustrated in F igure 5. This handle portion is also tubular and its interior has communication with the interior of the rubber bulb 17 through openings 18 in the handle 12. The rear end of the handle 12 is closed by a plug or the like 19, preferably ornamental in form.

The device is operated in the following manner.

The rubber bulb of. the handle is grasped, and the .flame encircling member is positioned around the flame as illustrated in Figure (l. Compression of the bulb forces the air in the interior of the bulb through the openings 18 through the tubular body portion 10, and a discharge thereof from the openings 13, the blasts delivered from said openings, impinging upon same. Relaxing of pressure upon the bulb 17 causes inflation thereof, the air being drawn inwardly through the openings 13, and the device is ready for the next extinguishing operation.

By :reason of the fact that the blasts of air are directed upwardly, the hot grease at the base of, the flame will not be splattered or scattered, since ,the blasts of air are so directed that they are never directed upon this hot grease.

While the invention has beenherein described in ,its preferred form, it is to be understood that it is not to be limited to the specific construction herein shown and described, but may be practiced in such other forms as rightfully fall within the scope of the appended claims.

Having thus described the invention, what is claimed as new and What it is desired to secure by Letters Patent of the United States, is:

1. A flame extinguisher comprising a tubular member terminating at one end in a flame encircling member, a plurality of air discharge perforations in the inner wall of said flame encircling member and adapted to discharge a plurality of individual air streams radially inwardly of said flame encircling member, and means for forcing air through said tubular member and said discharge openings.

2. A flame extinguisher comprising a tubular member terminating at one end in a flame encircling member, a plurality of air discharge openings in the inner wall of said flame encircling member, said discharge openings being so arranged as to discharge individual streams of air in a direction inwardly of the flame encircling member in such a manner that the said blasts of air converge and meet at a point in a plane parallel with but spaced from the plane of the flame encircling member, and means for forcing air through said tubular mem- 4 her and said discharge opening.

3. In a flame extinguisher, a circular flame encircling member tubular in form, and a plurality of air discharge openings adapted to discharge air radially inwardly of said flame encircling member, said discharge openings bein so arranged as to concentrate their blasts of air at a point above the base of the flame to be extinguished.

4. In a flame extinguisher, a circular flame encircling member tubular in form, and a plurality of air discharge openings so constructed and arranged that when the device is in flame encircling position, blasts of air discharged therefrom will be projected upwardly away from the upper end of a candle, the flame ofwhich is to be extinguished.
