A Homey Patented Oct. 27,193.1;l l d WILLIAM S. SINCLAIR 0F HOENIX, .ARIZONA HEAVY LIQUID Arrmca'ron.

Application led December 7, 1929. Serial No. 412,542.

This invention relates to applicators, and is particularly adapted to a p ying waving set solutions to hair that are eavy and sluggish li uids.

An o ject of the invention is to provide a relatively large casing or reservoir on the applicator that is capable of holding a considerable quantity of liquid without replenishing, and further to rovideA relatively e large Aorifices in the app icating lingers tov prevent clo ging thereof.

Another eature of the invention is to provide for applying pressure to the applicator to force the liquid therefrom as desired, and further to provide a relativel flat face on the tips of the applicati'ngl ngers to disn tribute the liquid with ease and dispatch. Further objects of the invention are to provide an applicator of the character referred to that is strong, compact and durable, veiiy simple in its method of assembly, highly e cient for its intended purpose, and comparatively inexpensive to manufacture and operate. I

With the foregoing and other objects in view, the invention consists of a novel construction, combination and arrangement of parts, as will be hereinafter more specifically described and illustrated in the accompanyso ing drawings, wherein is disclosed an embodiment offthe invention, but it is to be understood that changes, variations and modil cations ma be resorted to without departing from t e s irit and scope of the claim hereto appended.

In the drawings, wherein like refer ence characters denote corresponding parts throughout the several views Figure 1 is a side elevational view of the applicator in accordance with the present invention, partly broken away.

Fig. 2 1s a transverse, detailed section taken substantially on the line 2--2 of Fig. 1,

,Figa 3 is a section taken substantially on line 3-3 of Fig. 1,

Fig. 4 is a cross sectional view throu one of the applicating fingers taken sud)- stantially on line 4-4 of Fig. 1,

Figure 5 is a detail sectional view through the air intake portion of the collapsible bulb.

Referring to the drawings in detail, 5 indicates generally the hollow, rigid, elongated casing or reservoir that is formed of hard rubber or other non-corrosive materials. The hair wave set solution to be applied is laced in this casing 5. The casing 5 is closed3 at its outer end 6 and is open at its inner end as will beseen from the drawin The major portion 7 ogs the casing 5 is substantially ovate in cross section, as illustrated to advantage in Figure 2 of the drawings and the open end portion 8 'of the casin is of circular cross section, as best seen in igure 3 of the' drawings.

Formed integral with, and depending from the bottom of the substantially ovate portion of the casing is a series of spaced, rigid, longitudinally alined, applicating fingers 10 that are substantiall ovate in cross section'. The leading edge o each of the iin ers is rather sharp as indicated at 11. The ngers terminate in relatively blunt tips 12, the leading faces 13 of which are Hat and inclined.

A relatively large orifice 14 extends thru the axis of these ngers ofthe series 10, from a point intermediate the inclined leadin faces 13, which are spaced from the ends o the iin ers, and communicates at its inner end wit the hollow interior of the casing 5.

The portion 9 of the casin 5 is internally- 80 threaded as at 15 and threada ly seated therein is an annular removable plug 16. Only a portion 17 of the periphery of the plug, at the inner end thereof, is threaded and the balance of the periphery is formed to provide i a smooth, reduced portion 18 over which telescopes the neck 19 of the flexible, rubber bulb 20. A metal band 21 secures the neck 19 to thereduced portion 18 to prevent the escape 90 of air from the bulb at this point when pressure is applied to the casing 5.

Extending through the axis of the plug 16, is a circular passage 22 about the inner end of which is disposed a valve seat 23.v The passage 22 communicates with the bulb 20 and the interior of the casing 5. Aball valve 24 is urged outwardly againstV the valve seat 23 by the outer end of a helicali coil spring 25, the inner end of which is secured to a cross rod 26 and is anchored in the walls ofy the plug 16 about the passage 22.

The bulb 20 is provided with an air intake neck 27 which is formed integrally therewith and which extends outwardly therefrom. The air passage in the neck 27 is controlled by a flap check valve 28 which is mounted in the bulb and which is engageable over the inner end of the air intake passage in a manner illustrated to advantage in Figure 5 of the drawings. Obviously, when the bulb 20 is collapsed, the lap check valve 28 will prevent the esca e of air through the neck 27 but when the ulb 20 is returning to its normal shape the lap check valve will permit the passage of air thereinto.

It will be apparent that the valve 24 prevents liquid rom escaping from the casing 5 into the bulb 20. I

It is to be understood that by describing in detail herein any particular form, structure, or arrangement it is not intended to limit the invention beyond the terms of the claim, or the requirements of the prior art.

Having thus described my invention, what I claim as new is A heavy liquid applicator comprising an elongated hollow casing closed at one end and open at its other end, a plug threadably secured in said open end, an axial passageway in said plug, said passageway reduced in area toward one end to provide a valve seat, a spring pressed valve disposed within said passageway and normally abutting said seat, a ilexible bulb mounted on the plug and having an air intake passa e communicating therewith, and a check va ve controlling the air passage in a manner to pre? veililt the escape of air therethrough from the bu In testimony whereof I aflix my signature. i WILLIAM S. SINCLAIR.
