;9 claims.

In my prior patents,"1,-81 3,615 and 1,813,616, dated July 7, 1931, I have described and'broadly claimed a novel shaving brush whichenables one to heat the water passing to the bristles. In my present invention, I have'devised novel means to effect/the automatic ignition of the fuel,

and the automatic extinguishing of the-flame when the water has been heated to a predetermined temperature- Further objects of the invention are to simplify the construction so that the shaving'brush can be economically manufactured; to construct and coordinate the parts so thatthere will not be a fire hazard and the construction will fool-proof in use; and to provide forth'ehousing of the igniter unit to prevent accidents whenthe fuel is being poured into the fuel chamber? 7 With the above and other objects in view'as will hereinafter clearly appear, my invention 0 comprehends a'novel automatically ignited-and extinguished hot water shaving brush. 7

Other novel features of construction and advantage will hereinafter appear in the detailed description and the appended claims. 25 For the purpose of illustrating theinvention, I have shown in the accompanying drawing a typical embodiment of it, which in'practice ,-will give satisfactory and reliable resultsl Itis, lfiiowever, to be understood that the various instru- 30 mentalities of which my invention consists can be variously arranged and organized, and my inven tion is not limited to the exact arrangement and organization of these instrumentalities as herein set forth. i 35 Figure 1 is a side elevation partly broken'away of an automatically ignited and extinguished hot water shaving brush, embodying my invention.

which receives the container I.

Figure 2 is a side elevation, partly'brokenaway V Similar numerals indicate corresponding parts. I Referring to the drawing:

I designates a cup shaped container, closed at its bottom and open at its top and having withinit an'annulus of absorbent or wick'mate- 5 rial 2. 3 is an open ended tube secured in any desired manner within the container l, for example by spot welding at the bottom, and this tube forms a housing for an igniting unit 4 of well known construction and purchasable in the '1 open market. Beneath the unit is a spring 5 having its lower end preferably fixed, and this spring tends to move the igniting unit upwardly. The upper end of the igniting unit has fixed to it a novel flanged cover 6 closing the upper end '13 of the tube 3 when the parts are in closed position. A rod 1 fixed to the cover projects upwardly to contact with the concave bottom 8 of a water tank9. To prevent condensation in the tube 3 it is provided with an atmospheric port H opening through the bottom of a lower cap I l The outer periphery of this cap is preferably knurled and at its upper portion it is of reduced diameter and threaded as at l2.

The tank has depending from it a sleeve 13 in telescopic relationship with the container l and provided with rows of air ports [4, l5 and IS,

the ports in the different 'rows being preferably in staggered relation, and the two upper rows being smaller in diameter than the lowermost row. The bottom of the tank 9 is grooved near its ,outer periphery as at H to receive a sealing gasket I 8 of asbestos or other suitable material with which the upper end of the container I will contact when the parts are in closed position as will be understood from Figure 3.

The water tank 9 converges upwardly and terminates in a threaded enlargement I9 to receive the threaded apertured base 20 in'which the bristles 2| are 40 securely set. A valve 22 having a handle 23 may be employed if desired to control the communication between the tank 9 and the bristles 2|.

The tank 9 is preferably provided with an v annular recess 24 to receive the thermostatic members 25, any desired number of which may be employed, three of such members being shown. Each of these membersis of lei-metallic thermostaticmaterial having one end fixed to the wall of the tank and their outer ends free to move inwardly when the temperature of the water in the tank 9 has reached a predetermined degree to release their pressure against the inner wall of an outer sleeve 26 and permit it todrop sufl l v a:

ficiently to close the air ports l6, l and I4 and thus extinguish the flame. The lower end of the sleeve 26 is internally threaded to cooperate with the threads [2 or the cap ll.

The embodiment shown in Figure 5 is similar I to that shown in the other figures except that the V the spring 5 and screws it to the cap I'l.

' 21 engaging the thermostat will prevent the sleeve 26 is inwardly'curved to grasping portion for the user.

The operation will now be apparent to those skilled in this art and'is as follows:

provide a better base 26 is'unscrewed and the Water tank Alcohol 9 filled to a desired amount with water. or other ignitable fuel is'placed in the container I to saturate the Wick Zand the sleeves l3 and 26 are moved into the-position seen in Figure 3 with the outer sleeve 26 screwedto the cap H. The shaving brush is now ready for repeated operations. The user unscrews the sleeve 26and the spring 5 raises the igniting unit 4 and the inner sleeve i3 so that the openings l4, l5 and [6 are uncovered, and the sleeve 26 is raised into the position seen in Figure 2. The air entering the ports causes the igniting unit to glow and the alcohol is ignited, thus heating the water in the tank 9. The outer sleeve 26 is retained inits raised position bythe thermostatic members 25 contacting with its inner face until the water reaches a predetermined temperature, whereupon the members 25 will move inwardly to release the outer sleeve which will drop sufficiently toclose the ports I4, l5 and i6. This causes the burner to be extinguished as the flow of'air to the burner is cut off. The user then presses the outer sleeve downwardly against the pressure of The operator can now use-the shaving brush in the conventional manner, the hot water passing to the bristles. If the valve 22 is employed, such valve is of course opened. ,7 a

When the outer sleeve 26'is raised, the stop sleeve 26 being detached from the sleeve I3.

will slide over the thermostat.

The atmospheric vent l6 prevents condensation in the tube 3, so that the igniting unit' l will'ignite the fuel as soon as the sleeve i3 raises sufiiciently to uncover the air ports. The upper row of ports I 5 and I6 prevent the flame from the burner fiar-, ing outthrough such ports.

The bottom cap II has openings 28 to the atmosphere. trolled by a valve 29 of any desired character.

As shown, a rotary ported valve is mounted on the bettorn cap so that the valve may be turned to open or close the port ID as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patentis:--- j 1.
