DISPENSING rrLIoA'roR.

Application filed March 17, 1924. Serial No. 699,852.

This invention relates to applicators for liquid material having means in conjunction therewith for dispensing predetermined quantities of liquid to the applicator portion of the device to be applied in a suitable manner.

An object of the invention resides in providing an applicator in the form of a brush which is adapted to be provided with a container or tank for holding liquid material, and adispensing and measuring chamber for receiving a charge of liquid from the tank to be dispensed through the applicator or brush, means being further provided for controlling the admission of charges from the tank to the dispensing and measuring chamber.

Another object of the invention is to provide an applicator inthe-form of a brush having the bristle mounted in a head and provided with outlet openings in the head mounting the bristles, a measuring and dispensing chamber being provided on the side of the head opposite to the bristles so that liquid delivered thereto will be slowly discharged through the openings to the brush, while a tank is provided adjacent thedispensing chamber with a substantially large outlet opening communicating with the dis- 0 pensing chamber and having manually controlled means operating a closure for the opening, so that a charge of liquid may be admitted to the measuring and dispensing chambe in an exceedingly short space of time and before or by the time it begins to flow through the outlet opening to the brush, so that the charge of liquid to be dis pensed can be predetermined in substantially accurate quantities.

The invention also comprehends other objects and improvements in the details of construction and arrangement of the parts which are more particularly pointed out in the following description and claims, di rected to a-preferred form of the invention, it being understood, however, that variations in the form and arrangement of these parts may be made without departing from the scope of the appended claim.

In the drawing forming a part of this application:

Figure l is a vertical sectional view through 'an applicator constructed in accordance with this invention.

Figure 2 is a detail view showing a seethe tion of the bristle mounting and the manner of applying the outlet tube thereto.

1 indicates an applicator having a handle 2 and an enlarged head 3 which is hollowed out to receive the metallic tank member 4 which i adapted to contain suitable liquid which is put in the tank through a fillingwith a plurality of openings 12 adapted to receive concentric tubes 13 around which are posit oned the bristles 14 which are secured in the openings 12' in any desirable manner,

such as by the binding ring 15, more clearly illustrated in Figure 2 of the drawings which binds the bristles onto the tube 13 and which in concentric relation thereto, are adapted for a driving fit in the openings 12 of the brush heads 11. The inner or upper wall of the brush head 11 is provided with the socket 16 adapted to mount the bell crank lever 17, to one end of which is connected an operating rod 18 extending to the lever 19 carried in the recess 20 of the handle beyond the tank 4, as may be clearly observed from Figure 1, so that the end of the bell crank lever may be depressed by the finger for operating the bell crank lever 17, the other leg of which is connected by a link 21 to raise the closure member 22. The closure member includes a disc of substantially larger size than the opening 8 in the wall 7 of the tank which is provided with an annular seating member 23 having an internal annular recess for receiving the circumferential edge of the disc 22, said seatmember being formed of rubber or other suitable material adapted to cooperate with the wall 7 beyond the opening 8 therein for closing the opening against the passage of liquid from the tank 4 into the measuring and dispensing chamber. A coil spring 24iarranged in frusto-conical or tapering form from one end to the other is inserted in on its pivot in the bracket 16 for raising the disc 22 from the wall 7 of the tank and permitting the immediate dlscharge or" a quantity of liquid from the tank nto the measuring and dispensing chamber. By reason of the large size of the opening 8, the chamber would be completely filled immediately after the opening of the valve or disc 22 and before the liquid has had sufiicient time to discharge to any appreciable extent from the tubes 13 of the brush, so that a predetermined amount of the liquid is measured in the measuring and dispensing chamber and the lever 19 released to permit the spring 2% to reseat the disc on the Wall 7 and prevent a further discharge of the liquid from the tank 4-. The brush may now be applied to a persons head in case that it is desired to apply hair tonic and the tonic will be disposed trom the measuring and'dispensing chamber 9 in a gradual and slow manner through the tubes 13 so that the applicator may be worked over the hair to which the tonic is to be applied for gradually applying it thereto and rubbing it into the hair, the amount of tonic contained in the dispensing chamber 9 being sufficient to provide a single application to the hair for which a barber charges a certain sum.

More economical use and application of the hair tonic will thus result by using the present invention, and the customer will al vays receive a full treatment.

It is to be understood, however, that while the above is given as an example of the use ot this invention, it may be used in any case where an applicator is used for applying a liquid substance, and particularly where it is advantageous and substantially necessary to dispense predetermined quantities of the liquid to be applied.

l fhat is claimed is v An applicator comprising a handle member provided at one end with an enlarged head, the head being provided, at one side, with a recess, a. tank housed within the recess and having a flange disposed beyond the bottom wall of the tank, a brush head having perforations therethrough disposed within the flange and spaced from the bottom wall of the tank, said bottom wall of the tank being provided with a. central opening, a spring pressed valve located within the tank and normally closing the opening, a bell crank lever ,t'ulerumed on the brush head adjacent the opening and having one of its arms operatively connected with the valve by a short link tending to maintain the valve centered in relation to the opening, a second bell crank lever fulcrumed upon the handle member, and a link operatively connecting said bell crank levers together.

In testimony whereof I atlix my signature.

LLOYD D. JONES.
