FLARE TORCH Filed Sept. 8, 1934 M (r Jim Patented Oct. 4, 1938 PATENT OFFICE FLARE TORCH Rudolph Kovac, Chicago, Ill., assignor to American Automatic Devices 00., Chicago, 111., a cor- 1 notation of Illinois Application September 8, 1934, Serial No. 743,246

2 Claims.

My invention relates tofl are torches and has for its object the provision of a new and improved form and arrangement of parts by which a snuffing effect may be produced, by which a flag a staff may be held firmly in upright position above the body of the device for use as a signal when the torch has been snuffed, and by which a tight closure shall be provided about the wick for preventing the escape of the liquid fuel in case the device should be upset during the period when the flare is not lighted.

It is another object of my invention to improve devices of this type in sundry details hereinafter pointed out. The preferred means by which I have accomplished my several objects are illustrated in the drawing and are hereinafter specifically described. That which I believe to be new and desire to cover by Letters Patent is set forth in the claims.

In the drawing,-

Fig. l is a perspective View of the preferred form of my improved device with the snuifer in position thereon and with a flag mounted upon the snuffer;

Fig. 2 is a central vertical section through the device as shown in Fig. l;

3 is a top plan view of the receptacle proper with the wick and associated parts removed;

Fig. 4 is a fragmentary view showing a vertical section at line 4-4 of Fig. 3;

Fig. 5 is a central vertical section through the wick supporting means and the shielding means, substantially as shown in Fig. 2 but with the snuffing cap and the receptacle removed for clearness of illustration; and

Fig. 6 is a central vertical section through my improved snuffing cap removed from the remaining parts of the device.

As will be appreciated by those skilled in the art, devices of this general type have been wellknown for many years-see for example the torch shown. in Billingham U. S. Patent No. 181,030 of August 15, 1876, and the curling iron device as shown in Pitner Patent No. 536,839 of April 2, 1895.

As shown in the drawing, my device in its preferred form comprises a sheet metal receptacle H] having an opening at its upper end defined by an inwardly extending flange portion H and downwardly directed flange portions l2 and I3 at the inner edge of the flange portion II, the lower edges of the flanges l2 and i3 being obliquely disposedyas is best shown in Fig. 4, and having lugs it formed at their end portions adjacent to notches 5 at opposite sides of the device.

Means is provided upon the upper end of the receptacle for supporting a wick E8 in position, such means in the arrangement shown comprising a wick tube l'l having a plate iii in the form of a ring extending laterally at an intermediate point. A ring i9 is mounted about the wick tube I! immediately below the plate l8, such ring l9 having lugs 28 and 2| extending downwardly from the edge of the ring, with the lower end portions of the lugs turned outwardly. The arrangement is such that the lugs and 2i are capable of being entered through the notches l5 so as to bring the outwardly turned end portions of such lugs into engagement with the bottom faces of the downwardly directed flange portions l2 and i3. The arrangement is such that when the plate and tube are given a rotary movement in clockwise direction in Fig. 3 the plate l8 and gasket 22 carried thereby are drawn downwardly into tight engagement with the inwardly extending flange portion H of the receptacle it.

Upon the upper end portion of the wick tube I1, I have mounted a shield 23 in the form of a drum having its lower end partially closed by an inwardly extending flange portion 24 provided with a plurality .of air openings 25. Above the shield 23 I have provided a transverse plate 26 supported in position by a metal bow member 2? in spaced relation to the upper edge of the drum 23.

My improved snuffer device as shown in the drawingicomprises a cap 28 pressed out of sheet metal into the iorm'of a cup, with an outwardly offset portion 29 at the open end formed integrally with an intermediate outwardly extending flange portion 30. A gasket 3! of any approved type is mounted in the enlarged end portion of the cap in close proximity to the flange portion 30, being held in position in any suitable manner. At opposite side portions, the enlarged portion 29 of the cap is provided with notches 32 which extend longitudinally of the cap and then circumferentially thereof so as to provide lugs or arms 33, the upper faces of which are obliquely disposed. The arrangement is such that when the cap 28 is lowered into position about the upper end of the wick and its associated parts, the notches 32 engage lugs 34 pressed outwardly from a downwardly directed flange 35 on the plate It. Upon rotation of the cap in clockwise direction in Fig. 3, the lugs 34 by engagement with the upper faces of the lugs or arms 33 draw the cap downwardly for tightening the gasket 3i between the cap and the plate I8.

Means is provided upon the outer faces of the cap 28 for supporting a signal flag 36 in position. In the arrangement shown, this means comprises a strip of metal 31 bent into the form of a channel with the opposite side portions connected with the cap by means of flanges 38 or otherwise so as to provide an upright socket'at the side of the cap for receiving the staff 39 of the flag. In the arrangement shown, a cable 40 in the form of a chain is connected at one end with the lower end portion of the socket member 31 and is connected at its other end with a lug 4| mounted on the outer face of the receptacle l0.

With the parts in the arrangement as shown in Fig. 2, but with the cap 28 removed, a very eifective flare device is provided along the lines of the showing of the-prior art devices above referred to. An ample supply of air is admitted through the openings 25 for the production of a flame at the upper end of the wick, the flame being adapted to extend outwardly through the opening between the shield 23 and the plate 26 so as to beeifective as a signal device. The shield comprising the drum 23 protects the'flame from the wind at the critical point adjacent to the wick, and the transverse plate 26 protects the wick eifectively from the rain. As will be readily understood when the device is in use as a flare, the cap 28 willbe supported by the flexible cable 40 at the side of the receptacle 10;

When the workman desires to extinguish the flame, the cap 28 is dropped into position as shown in Fig. 2 serving quickly to snuff the flame and extinguish the fire; The cap can then be tightened intoposition as shown in Fig. 2 so as effectively to close the upper end of the device about the wick so that in case the device should be upset it will be impossible for any of the fuel to escape. With the cap 28 in position as shown in Figs. 1 and 2, a'flag 36 can be readily inserted in position, the receptacle l8 more or less completely filled with fuel serving as an eifective standard for supporting the flag in position.

While I prefer to employ the form of construe-- tion as shown in my drawing and as above described, it is to be understood that my invention is not limited to the formshown except so far as the claims may be so limited by the prior art.

I claim:- I I 1. In a device of the type described, the combination of a receptacle for liquid fuel having an opening at its top provided with an inwardly directed flange, a downwardly directed flange on said inwardly directed flange at each side of the receptacle having an obliquely disposed lower edge, awick tube, a plate mounted on said tube and extending outwardly therefrom, lugs extending outwardly from said plate in spaced relation thereabout, a cap having notches in its lower edge comprising obliquely disposed bearing face portions adapted by engagement with said lugs to lock said cap securely in position on said plate when the cap is given a rotary movement, a gasket interposed between said cap and said plate for providing a tight closure therebetween, a second gasket on the bottom face of said plate in position to engage said inwardly directed flange of the receptacle, and other lugs extending outwardly from said tube in downwardly spaced relation to said plate adapted by engagement with said downwardly directed flanges of the receptacle to lock said plate in closure position upon said opening.
