vand has for its object to provide a brush for the treatment of the scalp.
The brush according to my invention coniprises a body portion formed with one or "more reservoirs which contain liquid substances suitable for the treatment of the scalp, andteeth' having valve controlled channels leading from said reservoirs and through which `the liquids can be' at will -discharged onto the scalp during treatment. My invention lwill be more fully understood by reference to the accompanying drawing in which similar reference characters denote corresponding parts, and in which, Fig. l. isa sectional elevation of the brush; Fig. 2 a lon itudinal section on line 2-2 of Fig. 1, and' ig. 3 a cross section on line 3-3 of Fig. 1.
Referring to the drawing more in detail, 10 denotes the body portion oi the brush and 11 its handle. The body portion l0 is made hollow to form a tank or reservoir to contain suitable scalp treating liquid substances. The tank may be partitioned into separate receptacles, as at 12, each to contain a different substance.
In the present embodiment of my invention the tank is shown divided into two compartments 13. The top 14 of the body portion 10 is removably fixed to the latter by screws 15 or the like, and is provided with charge openings 16 normally closed by plugs or Stoppers 17. At its forward end, the top 13 is provided with air holes i8 for each compartment. Projecting from the bottom of the body portion 10 are tooth shaped members 19 the upper' ends of which are .tiXed in holes 10 made in the body 10. These teeth are provided with capillary bores, ducts or channels 20 extending centrally and longitudinally of said teeth with their inner ends 20 opening into the compartments or chambers and their outer ends 202 terminating a short distance above the lower ends of said teeth and' opening to the side of the latter. Slidably borne in grooves 102 made in the inner face of the bottom of y said compart lents are longitudinally eX- Y tendin Q strips 2i of metal or the like adapted to bear tightly over the parts of Athe bottom 1n which the'teeth 19 are lined.
,these strips are each provided with openings 21 which are spaced apart to contorni with the spacing of the teeth ot the correy .sr inding compartment and ot a size about l egual to the width oi the channels 20. ln normal position of said slides 21 the openings 21 are desplaced relative to the inner openings 20 of the channels 20 and said slides hold the said passages or channels 20 tightly closed. lfhen, however, the liquids are to be discharged from the compartments, the slides are shifted longitudinally until their pertorations 2l are brought to register with the inner ends 20 of the chanels 20. ySuitable packing means (not `-wn) may beprorided between the slides the botten closure. ri" 23. are bent upwardly and horizontally. r)The horizontal bends 212 are adapted through suitable packing means (not shown) to tightly bear against the inner tace of the top 11i and to extend over that portion of the top in which the air holes 18 are arranged. The horizontal portions 212 et 'said slides are provided each with anopening 213 which when the slide is displaced into open position will be brought in register with the corresponding air hole 18 to admit air into the compartments and thereby permit the liquids to flow from the latter into the pas` sages 20. The rear end 214 of each slide is also bent upwardly and bears against a spring fniounted in a groove 103 provided in the rear wall of each compartment. These springs 22 tend to shift the slides 2l fon wardly. and retain them in closing position. For the operationot the slides l provide bell crank lever 23 tor each slide. These bell crank leversare mounted in grooves 11 oi the handle 11 and 4are fulcrumed therein. The forward arm of each bell crank lever is slotted as at 23" to engage a pin 24 which projects troni the rear end 214 of each slide. rlhe rearward ends oi" said bell crank levers are bent laterally and extend outwardly through cross grooves 112 leading from the oic the tank to produce a he forward ends ot' the strips or slides" longitudinal grooves 11 and carry knobs 25" to close the upper' ends of the passages 2O and also the an' holes 18. When itis desired to discharge a liquid from one or another compartment or both, the corresponding slides are shifted by swinging the levers 23 whereby the openings 21 in the slides are brought Yto register with the inner ends of 'he teeth 19 and the opening 213 with the air holes 18. The liquids Will then flow through the channel passing outwardly through the sides of the' teeth 19. Owing to the arrangement of the lower openings 202 at the sides ofthe teeth, the same Will not be clogged While the latter bear on the scalp. rEhe Width of the channels 20 is made suniciently small so that the liquids will be discharged by capillary action in small drops.
Itis7 of course, understood that the construction may be modified in various Ways Without departing Yfrom the spirit of my invent-ion. l, therefore, do not Wish to restrict myselrn to the details described and shown.
/Vhat l claim and desire to secure by Letters vPatent is 1. In a brush, a body portion formed with a tank divided into compartments to contain different liquids, teeth fixed in the bottom of said brush and having channels leading from said tanks, slides in said compartments to control the flow of the liquid therefrom into the channels and means for operating said slides.
2. In a brush, a body portion formed with tank for'liquids and having a remova lev top, said top having air holes, channeled teeth lined in the bottomA of said tank and the channels ci Which communicate with the ylatter, a common valve to control the opening and closing of said channels and airholes and means for operating said valve..
In a brush, a body portion formed with a tank divided into compartmentsto contain diderent liquids,'teeth in said brush having channels leading from said compartments and independently loperable valves it'or controlling the flow of the liquids from said compartments through said channels.l
