signor to Cardinal Products, Inc., a corporation of New York Application June 28, 1933, Serial No. 677,987

13 Claims.

'I'his invention relates to lighters, of the class employing a catalytic element, such for example as platinum black, to co-act withthe vapor of a vaporizable uid, such as alcohol, in the presence of air, to render the catalytic element incandescent, so that it may serve to ignite a cigarette or the like applied thereto. y

In my earlier U. S. Patent No. 1,899,008, dated February 28, 1933, and in my patent application for Lighter, Serial No. 673,257, tiled May 27, 1933,

I have disclosed lighters of this general character, wherein the vaporizable fluid is contained by absorbent material that is held in a casing; but in the present development I provide a container for vaporizable uid in liquid form, providing said container vwith a small nozzle orice, from which a flow of fluid vapor can be had as by the application of a cigarette to the element, which is perforated, and drawing upon the cigarette to aiord the necessary suction effect, the provision also being made for a flow of air over the nozzle, for admixture in a mixing chamber with fuel which is drawn from said nozzle.

In some instances I may employ either a wick or a capillary tube, to communicate the fluid from the container to the nozzle orice.

A removable cap is provided to enclose the catalytic element and the mixing chamber.

Also, in order that fuel may not leave the nozzle while the catalytic element and the mixing chamber are enclosed by the removable cap, I provide closure means for the nozzle, spring urged to the nozzle open position when the cap is 01T, but operative to close said nozzle in the act of placing the cap on the casing to enclose the catalytic element and the mixing chamber.

Still further my improvement includes the provision of an additional catalytic element, contained in a socket member, for replacement purposes, and carried when not in use in the rear end of the casing.

Other features and advantages of my invention will hereinafter appear.

In the drawing: .o

Figure 1 is a vertical, sectional, view of my improved lighter, with the cap removed.

Fig. 2 is a similar view of the cap.A

Fig. 3 is a horizontal section, taker. on the line 3-3 of Fig. 4.

Fig. 4 is a partial view, similar to that of Fig. l, showing closure means for the nozzle in the released, open position.

Fig. 5 is a similar view to that of Fig. 4, but showing the cap applied, and the nozzle closure means thereby placed in the closed position.

Fig. 6 isa partial detail view of the plug, showing the use of a capillary tube to supply the fuel to the nozzle, and

Fig. 7 is a partial view showing a modied form of casing, open at its lower end and having a cap 5 removably tted therein, -said cap being hollow and having removably lodged therein a socket member that carries an auxiliary catalytic element, for use in case the element in use becomes broken. 10

In said views let I indicate a casing, which may or may not be provided with an outer covering 2, and let 3 indicate a container which is adapted to contain a suitable vaporizable fluid, said container having at its outer end an interl5 nally threaded annulus 4, which may be integral with or secured to said container. A plug or boss 5, having an inner, threaded portion 6, is adapted to be screwed thereby into union with the annulus 4,. said plug having a concentric, 20 knife-edged portion 1, opposed to the outer surface of annulus 4, and adapted, when the plug is screwed tightly into the annulus, to impinge upon said outer surface, to thereby create a iluid and vapor tight joint. 25

The outer, central portion of plug 5 is provided with a nozzle structure 8 which has an axial orifice 9 for the emission of vapor from the fluid in the container, and, as here shown, said orifice communicates with a concentric enlargement II) 30 through the inner portion 6, which enlargement may receive one end of 9, wick II that is immersed in the iluid in the container to supply fluid by capillary action to the nozzle orice. The wick is shown as lodged in the plug by means 35 of a transverse pin I2. In the modification of Fig. 6 I have shown a capillary tube A, which extends from the plug 5 to near the bottom `of container 3, and registers with the orice 9 to supply Iiuid thereto. 40

Also the plug, at its outer portion, is provided with a concentric wall I3, surrounding the nozzle structure 8 and creating an enclosure I4, said wall being pierced with air admission orices I5, whereby said enclosure I4 becomes a mixing 45 chamber for atmospheric air and vapor.

A hollow holder I 6, which supports the catalytic element I1 at one end, said element being perforated as at I8, is adapted at i-ts other end to t removably upon the casing I, the wall of 50 said holder, which is spaced from the wall I3, being provided with air admission orices I9.

The catalytic element is here shown as carried by a socket member whose wall 20, at its outer edge, is provided with a. radial ange 2| 55 that lies opposed to and abuis against an inturned flange 22 at the outer end of holder I6, means, here shown in the form of a split ring 2l, which engages the wall of the holder, serving to retain the socket in its set position. The catalytic element is held within the socket by means of an inturned flange 24 at the inner end of socket wall 20 and by the aforesaid holder ange 22.

In Figs. 3 to 5 I have illustrated an additional feature in the form of closure means for the nozzle orifice 9, said closure means as here represented including an arm 25, pivoted at one end to the wall |3,'as at 26, and extending across chamber I4, said arm bearing a sealingprotuberance V21 adapted to co-act with orifice 9, to close it, butsaid arm being urged, as by a spring 2l, which extends from plug 5, away from said orifice, to leave it open. Thus, when the cap,

hereindicated at 29, is removed from the casing, at which time it is desired 'to have vapor issue from'orliice 0 for co-action with the catalytic element, in the presence of air, then the device will be in operative condition and the catalytic .element will be rendered incandescent for ignlting 11111D0563- 4 But whenclosing the device by the application of cap 29, then it is desired to also close orifice 0, for which purpose the cap 29 is here shown as provided with an internal collar I0, and the length of arm 25 is extended so that its outer end, which projects through a slot 3l 4provided therefor in the wall of holder l0, willlie in the path of collar 30, which will thus press arm 25 inwardly in the closing acton of the cap, and thereby cause the protuberance 21 to become seated upon the nozzle l, to seal the orifice 9.

As means for breaking the vacuum in the fuel chamber 3 and thus permitting the fuel to fiow through orifice 9 I provide venting means as by the passageway 32 formed through plug 5.

AlsoI may provide an vextension 33 of the cylindrical wall of casing I and removably fit to said extension a cap Il. here shown as threaded and adapted to screw into said extension. Said cap, being hollow, is adapted to removably receive a supplemental socket 20 containing a catalytic element l1, so that in the event of breakage or a other damage to the catalytic element in use this supplemental socket and element can take^its place. The socket is here shown as having perforations 35 in its bottom instead of in itswall. Variations within the spirit and scope of my invention are equallycomprehended by the foregoing disclosure.
