1 Claim. (C1. 15-184) This inventionrelates to cosmetic implements in general and more especially to lip cosmetic brushes.

Among the objects of the present invention it is aimed tov provide an improved cosmetic brush for applying color- 'ing matter. to lips and the like which includes a casing within which the brush unit containing the coloring matter may be enclosed from contact with the person of the user when not in use and which brush unit may with facility be expelled or extended for use.

It is still another object of the present invention to provide an improved. cosmetic brush for applying coloring matter to lips and the like which can be readily placed in the purse or bag of. a user without danger of soiling the contents of the bag of user and which implement in turn may be actuated into operative use with facility requiring no contact with the brush unit by the user either when withdrawinglthe same into nonuse or extending or projecting the same into operative position.

These and other features, capabilities and advantagesof the invention will appear from the subjoined detailed description of one specific embodiment thereof illustrated in the accompanying drawings, in which- Fig. l is a side elevationof the implement with the brush unit withdrawn and a cap in place ready to be deposited into the purse or bag of a user. I

Fig. 2 is a side elevation of. the implement with the cap removed in position to have the brush unit eject or extend into operative position.

Fig. 3 is a longitudinal section of the implement illustrated in Fig. 2 in the withdrawn position of the brush unit. I

Fig. 4 is a longitudinal sectiongof the implement illustrated in Fig. 2 after the brush unit has been ejected or extended. h

Fig. 5 is a side elevationof the implement with the brush unit extended as shown in Fig. 4. i

Fig. 6 is an exploded view of the parts illustrated in Fig. 4 with the collet on the brush unit shown in position where the brush unit is projected or ejected as shown in Fig. 4. V

Fig. 7 is a side elevation of the brush unit as illustrated in Fig. 3 where the collet is in position to anchor the brush unit in withdrawn position.

The embodiment illustrated is provided with a main shell 1 preferably having a conical front end 2, a closure unit 3 and a plunger projection 4 at the end of the plunger 5 having the first collar 6 intermediate its ends to form an abutment for the coil spring 7 which is tensed between the collar 6 and the cylindrical unit 8 frictionally anchored inside of the main shell 1. The plunger 5 preferably is split as shown by the longitudinal division 9 to enable the plunger 5 to yield to but frictionally receive the rear end 10 of the collet 11 which is slidably mounted on the rod 12 of the brush unit having at its front end the extended ferrule 13 at the front end of which extended ferrule 13 there are secured the'bristles or hair unit 14. The rear end of the ferrule 13 acts as an abutment or stop for the forward movement of the collet 11 ice . or the rearward movement of the brush'unit 15 and to determine the innermost position of the brush unit 15 in retracted position as shown in Figs. 2 and 7. Adjacent the rear end of the rod 12, a second collar 16 is mounted which acts as a stop for the collet 11 in its rearmost position relative to the brush unit 15 and in turn determines the foremost position of the brush unit 15 when in ejected or extended position as shown in Figs. 4 and 6. From the foregoing it will thus appear that the plunger 5 and rod 1 act as an integral unit and that the collar 16 acts as a first stop member on the brush unit to cooperate with the rear end of the collet 11 as a second stop member, to determine the extreme ejected position of the brush unit as shown in Fig. 4. r

The collar 6 of the plunger 5 is preferably larger than the cylindrical opening 17 in the cylindrical unit 8 so that it will effectively act as an abutment to cooperate with the cylindrical unit 8 to capture the spring 7 within the main shell 1.

The closure 3 preferably has an outer cap formed enlargement 18 with a shoulder 19 intermediate the diminished portion 20 and the enlargement 18 to cooperate with the rear end of the main shell 1 when the closure 3 is forced into the rear end of the main shell 1 when the front end 21 of the closure 3 will serve as the limiting stop to cooperate with the collar 6 to capture the plunger 5 in operative relation with the spring 7 in the main collet from near the rear ends of the slits 22 flares out-' wardly to a point 23 adjacent the front end of the collet 11; From the point 23 the collettapers inwardly for a short distance to the front end 24 of the collet 11. The long outwardly flaring surface 25 to the rear of the point 23 of the collet 11 alone contributes to gripping the rod 12 by the collet 11.. The outer periphery of the collet 11 just rearwardly of the point 23, see Figs. 2 and 4, even when the jaw is compressed into intimate engagement with the rod 12, will not pass through the cylindrical opening 17 in the cylindrical unit 8 so that when the spring 7 expands under its own momentum when released it will anchor the collet 11 on the rod 12 wherever it may be situated. If the rod 12 is retracted as shown in Fig. 2 and the collet 11 is in engagement with the ferrule 13 and the plunger 5 is released, the collet will intimately engage the rod 12 adjacent to the ferrule 13 as shown in Fig. 2. If, however, the brush unit 15 is ejected or extended into operative position as shown in Fig. 4 and the plunger 5 is then released, the spring 7 will move the plunger 5 rearwardly and with it the rod 12 and collet 11 to cause an intimate engagement of the rod 12 by the collet 11 in the position shown. in Fig. 4 where the rear end of the collet 11 will be adjacent the collar 16. The action here achieved of course relies upon the fact that when the collet 11 as an instance is positioned on the rod 12 adjacent the ferrule 13 as shown in Fig. 2, and the plunger 5 is released, the action of the spring 7 when actuating the plunger 5 rearwardly will carry with it the collet 11 only until it is arrested by the cylindrical unit 8 engaging the enlarged portion of the collet 11 adjacent the point 23. Consequently, if the brush unit 15 is positioned relative to the collet 11 as shown in Fig. 2, that is with the rear end of its ferrule adjacent the front end of the collet 11 and the plunger 5 is then released, it will cause the rod 12 to be intimately engaged by the collet 11 and in turn anchor the brush unit 15 in retracted position inside of the main shell 1.

On the other hand, if the plunger 5 has been depressed v Patented Nov. 24, 1959,

to-cause the collet 11 to move forwardly a sufiicient distance to clear the cylindrical unit 8, then. when the implement is positioned so that the front end extends downwardly while the plunger is still being depressed, the brush unit 15' will drop down into the extended or ejected position shown in Fig. 4-. In turn, when it is desired to retract the brush. unit 15, it will only be necessary to position the implement'so that the front end extends upwardly, then depress the plunger button 4 and the brush unit 15 will drop down into retracted position.

When it is desired to store the implement in a purse or bag when not in use, the brush unit 15 will first be ret'racted into the position shown in Fig. 2 and then the cap 26 shown in Fig. 1 positioned on the front end of the main shell 1. In order frictionally to anchor the cap 26 on the shell 1, the shell 1 is preferably provided with the protrusions 27 which will snugly engage the inner face of the cap 26 and frictionally anchor the cap 26 in the position shown in Fig. 1.

From the foregoing it will be seen that in the extended position of the rod 12, see Fig. 4, the front edge of the conical end 2 will engage the exterior ofthe extended ferrule 13 to cooperate with the closure unit 3 in engagement with the plunger 4 and the gripping jaw 24 of the collet 11 in engagement with the rod 12 to anchor the ferrule 13 and therewith the bristles 14 in operative position.

- In the assembly of the device the cylindrical unit 8 is frictionally positioned in the casing or shell 1 at a position, see Fig. 2, where the enlarged portion of the collet 11 will be engaged by the front end of the cylindrical unit 8, the rear end of the ferrule 13 positioned adjacent to the front end of the collet 11 and the bristles 14 positioned clear of'the front end 28 of the casing or shell 1. The brush unit 15 with the ferrule 13 and the collet 11 and the collar 16 will' be inserted through the opening in the front end 28 ofthe casing 1 into a position where the collar 16 extends rearwardly of the cylindrical unit 8, the spring 7' then inserted through the opening in the rear end 29 of the casing 1 so that it rests on the cylindrical unit 8, thereupon the plunger inserted through the opening'in the rear end 29 of the casing so that its front end portion 30 constituting a gripping jaw frictionally grips the rear end of the collet 11 as shown in Figs. 2 and 4 and thereupon the closure 3 is forced through the opening in the rear end 29 frictionally to engage the inner periphery of the casing or shell 1 as shown in Figs. 3 and 4; Preferably the closure 3 as shown in Fig. 6 is roughened at 31 to provide an effective frictional face for engagement with the inner face of the shell or casing 1.

While a number of parts of the unit may be composed of a plastic material or metal without departing from the general spirit of the invention, itis noted that excellent results have been achieved when the cap 26 and main shell 1, collet 11, ferrule 13 and plunger 5 are composed ofa brass such as 85/15 Richlow brass or 70/30 cartridge brass and when units such as the cylindrical unit 8,

closure 3 and rod 12 are composed of zinc known as Zamak. No. 3, the spring 7 is composed of spring steel and the bristles 14 are composed of red sable.

It is obvious that various changes and modifications may be made of the details of construction without departing from the general spirit of the invention as set forth in the appended claim.

I claim:

A cosmetic lip brush having a casing having a front contracted open end and a rear open end, a cylindrical unit fixed in said casing spaced from said front open end andhaving an axially extending opening therein, a brush unit slidably mounted in said cylindrical unit and having a rod, an extended ferrule mounted on the front end of said rod, and a first stop member on said rod, a plunger having a chambered collet slidably mounted on said rod, said collet being disposed between said ferrule and said first stop member and having an enlarged gripping jaw at its front end in front of said cylindrical unit, said gripping jaw having a diameter larger than the opening through said cylindrical unit to cause said jaw to grip said rod when urged into engagement with said cylindrical unit,

said brush unit having bristles in the front end of said' ferrule, said plunger having a second stop member cooperating with said first stop member to determine the extended position of said bristles, said plunger having a collar, and a spring interposed between said cylindrical unit and said collar and a closure having a central opening through which the rear end portion of said plunger extends, said spring and collar cooperating with said cylindrical unit and said collet cooperating with the rear end of said ferrule to capture said plunger in said casing whereupon pressure upon the rear end of the plunger will compress the spring to release the collet from the rod and allow the brush unit to move either into retracted position where the bristles are completely enclosed within said casing or to move into an ejected position where said bristles protrude and the release of said plunger will enable the collet by engagement with said cylindrical unit to grip and anchor said'rod'in the ejected or retracted position, said contracted open end conforming to the outer periphery of said extended ferrule snugly to engage the same when said ferrule ispositioned in said contracted open end to cooperate with said gripping jaw in engagement with said rod firmly to anchor said ferrule and therewith said bristles in any one of a number of operative positions.
