The invention relates to fountain-combs embodying means for holding and discharging liquids or semi-liquids used in the treatment of the scalp or the hair.

The main object of the invention is the provision of a comb which externally, as regards size, shape, weight and convenience of handling, is not unlike the ordinary comb; the interior however is channelled and provided with simple autol matic mechanism by means of which mechanism one can ll the reservoir and discharge its contents, in whole or in part regulated according to desire.

With these and other objects in view the invention presents a new and novel construction and combination of parts described and shown in the accompanying drawing forming a material part of this disclosure and in which,

Fig. l is a longitudinal section taken through my improved comb.

Fig. 6 is afragmentary elevational view showing an embodiment of my invention.

Referring now to Fig. 2, of the drawing, IIJ represents a channelled dispensing comb in'which II is the reservoir, the forward portion of which holds the liquid or semi-liquid (to be dispensed) and the rearward portion of which has automatic mechanism for filling the reservoir and/ or emptying it of its contents. In continuation with the forward part I2 of the reservoir there is a stud I3 (details of which are shown in Fig. 5), having its outer portion, towards the forward end of the comb, solid, and its inner portion adjacent to the reservoir channelled longitudinally at I34, forming a continuation of the reservoir. There are several apertures I3I, I32, 33 (Fig. 4), of variable size, in the wall of the channelled part of the stud. By turning the stud one way or another (the predetermined positions being marked on the exterior surface of the head of the stud) the apertures may bebroughtin or out of line with the connecting duct I I I, which leads to the distributing channel I9, thus regulating the rate of discharge. When said apertures I 3I, I32, |33, are turned out of registration with said duct I I I, it is naturally blocked so that no liquid may `ilcw I.l Il) therethru. The stud I3 is removable for the purpose of lling the reservoir, (by pouring the liquid into the reservoir or sucking it thereinto after the manner of a syringe) The distributing channel I9, is usually of much smaller diameter 5 than the reservoir, with which it communicates b-y way of the connecting duct III, and stud I3, as described above. Through a number of apertures ISI, in its wall, the distributing channel is also in communication with a series of discharge l channels 20|, which run through the combs teeth 2), and open at the termination of the teeth or at any desirable place along their surface.

The operating mechanism of the comb consists of a piston 01 plunger I4, preferably cylindrical in shape. The diameter ofthe piston corresponds withthe diameter of the reservoir Il, in which it moves longitudinally one way or another, in a manner similar to the plunger of a syringe. The forward end of a coiledextensible spring I5 is firmly attached to the piston as at MI, while the other end I5I rests against the bottom of the reservoir. At the juncture of the piston and spring Iil there is also attached one end of a pull chain or cord Il. The cord passages through the channel formed by the coils of the spring and emerges from the reservoir through asmall aperture I8, at the backward or handle part of the comb. `A few inches of length of this cord hangs outside the comb to provide a good grip for pulling it. When the cord is pulled it causes the spring to contract bringing the piston towards the bottom of the reservoir (in this position the reservoirl is filled; either by suction or by pouring the liquid in,having first removed the stud I3). When the cord is released it automatically releases the spring permitting it to expand and push the piston forwards toward the stud I3. The stud blocks the expulsion of the liquid from the reservoir if its apertures I3I, I32, |33 are out 40 of alignment with the connecting duct III of the distributing channel I9 or permits a faster or slower rate of discharge according to whether a larger or smaller apertures is brought in alignment.

The mechanism described above, because of its simple construction and operation also because itis composed of very few parts, so that barely anything can break down, is considered best suited -for general use. However there are special needs in beauty and vbarber establishments requiring the use of larger quantities of liquid than may practically be stored in the reservoir II. I have therefore designed modifications of my comb with the View of satisfying such requirements.

Fig. 1 discloses a dispensing comb having the same basic design as the one described above and shown in Fig. 2, except for modifications in the mechanism. The piston I4, instead of being attached directly to the spring I5, is joined to one end of a notched ratchet bar |42, the other end of the bar being attached to the spring |5. The bar is passed through a pawl shaped like a tennis racket frame 22, the handle of which 222, emerges on the outside of the comb. There is a spring coil 25 about the outside portion of the handle and a little overlapping button 223, at its terminus. The action of the spring 25, causes the pawl to normally engage the notched bar and prevent it from moving forward. If the button 223, is pressed the pawl disengages and permits the notched bar to move forward a desired known distance such as the distance between the faces of two or more ratchet teeth. Thus the volume of liquid which occupied the space through which the plunger regulatively moves may obviously be predetermined as may the whole quantity occupying the chamber, simultaneously permitting the pressure in the mechanism to be exerted upon the liquid.

Fig. 6 discloses a dispensing comb having no reservoir and no mechanism for the expulsion of the liquid. This comb dispenses liquid by way of gravity. A storage container 3|), is suspended from a stand, ceiling or wall at a point above the comb. A suitable length of pliable hose 3l, is attached, at one end, to the container, the other end slipped over the projecting nipple 32, of the comb. Regulating mechanism preferably in the form of a screw valve |36, or the like, intercepts the flow of liquid through the discharge channel. Turning the screw valve |36, one way or another regulates or stops the flow of liquid through the comb.

Whenever very fine distribution of the liquid used, is necessary, as for instance, in the case of hair coloring, I removably attach a fine toothed ordinary comb to my dispensing comb, one directly trailing the other. Said fine teeth aid the more minute distribution of the liquid.

As many apparently widely apparent embodiments of the invention could be devised without departing from the scope thereof it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.
