This invention relates to improvements in fountain combs or devices, used for treatingv the hair or scalp with oil, tonic or other liquids, which comprise a container for the liquid, and teeth adapted to be moved through the hair and provided with discharge ducts for delivering the liquid on the scalp or at the roots of the hair.
A principal object. of the invention is to provide an improved fountain comb or applicator of this character which is of novel` construction, whereby the scalp or the. roots of the hair can be efficiently treated and the delivery of theliquid theretonicely regulated as desired, and: clogging or stopping of the discharge orices of the teeth prevented.
Other. objects of the invention are to make` the device of a novel construction which adapts it to beused for massaging and'treating the .scalp without irritation and without clogging the liquid delivery orifices of the teeth with dandrui orother matter; in which the outery ends of the teeth and of their discharge passages are. covered by protecting caps provided with smooth,
imperforate, outer ends adaptingvthemfor use' in massaging the scalp without irritation; in which the several teeth are. provided on a single tooth block or piece which is removably secured to the liquid receptacle or comb'body so .as to adapt all of the.Y teeth with, their dischargev cony trolling valves ,to be readily attached andremoved as a unit, thereby facilitating the yassembly of the device and the quick easy cleaning of the liquid delivery ducts or orifices and other partsof the device.
Further objects and advantages ofthe invention will appear from the following specification of the preferred embodiment thereof,kshown in the accompanying drawing, and the novel features of the invention are set forth in thev appended claims.
In said drawing:

Fig. 4 is a transverse section thereof on vline .1 -4, Fig. 3.
Fig. 5 is a side elevation of the tooth block and teeth detached.
Fig. 6 is a sectional View of the air vent for the' liquid receptacle.
Tbecomb `comprises a hollow body l0 lwhich155 provides a. receptacle for the oil, tonic or other liquidandteethill which project from one side of .the Abody .andareprovided withducts orpassages vcommtuicating with the. receptacle for de- .liverillgthe Yliquid from .the receptacle through the;teeth. 1`freferably the. body l0 is. in the. form of va shape. .adapting the comb to be comfortably heldin the. hand whilemanipulating or .using it. As shown,..the handle1 is of tubularform and the-receptacle-.body l0 is secured thereto by. inserting one endpofthe body tubewith a tightflt inthe cavity of1 the handle. A circumferential col1ar.| 3,. which/is shown on the body IU, fits tightly against the end of the 'handle to prevent .any liquidwhich might be present on the exterior of the body from entering, .the cavity of the handle. Thebody receptacle l0..shown, hasa filling opening at its outerend, closed by ascrew plug l4, and the inner end vof the receptacle is also shown vas closed by ascrew plugv or; cap. l5.
The teeth Il, which ,are tubular or have longitudinal passages orducts I6. therein, arejoined to and vpreferably;made integral with a tooth .block Il, Awhich isremova-bly secured tothe. body Yits inner side with vtubular nipples 22, one in alinement 4ivithreach tooth, which are adapted to t snugly in sockets'formed in the boss I9. Yielding washersv23- may also be usedbetween the ends of the nipples 22 and the inner ends of the nipple sockets, if necessary, .to further insure against Aleakage of liquid from the receptacle Vonto the outer surfaces of the comb. Holes 25 .through the boss I9 or side of the receptacle establish communication between the interior thereof and the discharge ducts of the several teeth. The gasketll extends around all of the .tooth and theouter endof the longitudinal duct .thereof. `Thiscap `preferably surrounds .and is 2 f l 'n 2,259,931
slidable in and out on the outer 'nd of the tooth and is provided with a smooth and preferably rounded or semi-spherical, imperforate, outer end adapted to contact with and be moved against the scalp without irritating it. Each cap 5 may be screwed or otherwise suitably secured to the outer end of a stem 21 which extends into the passage l5 of the tooth and is formed with or connected to a valve 28 adapted to cooperate with a seat 29 in the tooth passage for control- 10 ling the discharge of liquid from vthe tooth. Preferably the valve and seat are of conical shape, and the valve is normally held closed or against the seat to prevent the discharge of liquid, by a coil spring 30 arranged in the tooth 15 pressing the cap 26 inwardly, as by gently press'- 20 Ying the cap against the scalp. The construction and mounting of the cap is such that it provides anV escape opening or orifice for the discharge of the liquid from the tooth, which opening is spaced back or upwardly from the outer end of '25 the cap so as to prevent the same from becoming clogged or stopped with dandrulf or foreign matter which may accumulate on the end of the cap in the use of the comb. For instance, the cap is provided with discharge orifices 3l in its side 30 walls at a substantial distance back or upwardly from the end of the cap. When the cap is pressed inwardly and the valve is thus unseated or opened, the liquid can discharge from the tooth through the discharge orices of the cap-T As shown, the length of the several teeth varies so that the outer ends of the caps inv their normal positions are disposed on an arc conforming to the contour of the scalp. Thus, the several teeth will normally contact-simultaneously with 40 the scalp in the use of the comb.
By the provision of the caps with the smooth or rounded, imperforate outer ends, they can be moved backand forth in contact with the scalp in the use of the comb so as to gently massage '5 the scalp without irritating it, and they prevent dandruff or other foreign matter from getting into and clogging or stopping the discharge ducts or orices of the teeth so as to interfere with the proper delivery of the liquid to the scalp or roots;
of the hair. Therefore, the treating liquid can be delivered, and its delivery controlled as desired, to the root ends of the hair or to the scalp only, without greasing or wetting the hair above its root end portions, and the comb can be used' 55 to gently massage the scalp without danger of clogging the discharge orifices of the teeth or injuring the scalp. By making the teeth integral with the tooth block l1 as shown, the latter and all of the teeth can be conveniently die-cast in 50 a single piece, and the whole group of teeth together with the valves and caps carried thereby can be removed by simply unscrewing the two screws. This makes it possible to very quickly and easily clean the parts and prevent themv,
from becoming clogged, fouled or gummed u with accumulating matter.
In order to enablethe use in the comb of oils or liquids which may be too heavy or thick to flow readily at normal temperatures, the device,`
as heretofore known, may be provided with an electric heating element 32 which, as shown, extends into the liquid receptacle through the plug I5V at the inner end of the receptacle. y This heat- .ing element may be of any known or any suit- '75 able construction and may be supplied with electric current by conductors 33 and 34, under the control of a suitable switch 35, which enables the operation of the heating element to heat the liquid as may be required. The liquid receptacle is also shown as provided with an air vent device 36 for admitting air to the receptacle when this is necessary, to insure proper delivery of the liquid from the teeth. In using the device with some liquida-a special air vent is not necessary and may not be desirable, while, with other liquids, it may be. The vent is therefore prefer-- ably constructed so that it can be opened or closed as required. The vent shown consists of a plug 3l screwed into a hole in the top or back of the liquid receptacle and equipped with a rotatable cap 38 having a hole 39 in one side of the cap adapted, by rotation of the cap, to be placed into or out of registration with an air passage 40 extending through the plug.
