A 2.' Claims. l
This invention' relates to shavlng'brushesY and more particularly to shaving 'brushes'of the type having handle: reservoirs' from which shavingV cream can be dispensed' into the bristles ofthe brush head for use in producing lather.
An important object of the present invention is to provide a `shaving brush having a reservoir handle and spring means for urging contained shaving cream into thebristles of the brush head when valvular means operated. V
Another .object of the invention is to provide a reservoir type shaving brush wherein spring dispensing means is. employedy for extruding vthe shaving cream into .the .bristles ofthe brush and wherein meansis providedfor holdingthesaid spring means in retracted'positionwhilethe reservoir is being recharged.
Still another object of the invention is* to provide a brush of this character wherein the various mechanical.expedienciesvare coordinated and arranged in a compact manner capable of posi.- tive actionv and `foolproof operation under substantially all conditions.
Other objects and advantages of the invention will becomeapparent to the reader of the following description.
In the drawings: y

Figure 2 is an enlarged longitudinal sectional view through the brush, showing the spring pressed follower released.
Figure 3 is a fragmentary longitudinal sectional View showing the follower held in retracted-position.
Figure 4 isa fragmentary longitudinal sectional viewoi the shell.
Figure 5 is a cross section taken on line 5-5 of Figure 2.
Figure 6 is atop planview .ofthe follower.
Figure 7 is a'fragmentary detailed sectional view taken on line 1-1 of Figure 2. n
'Referring' to v the ..drawing's',z numeral 5 yden'otes a cylindrical shell, having a bottom 6 inwardly of its lower end, this end portion of the shell defining a socket in which the inner ends of the brush bristles are suitably anchored.
The brush head which is made up of bristles 'I projects beyond the lower end of the shell 5, as in the manner shown in Figure 2, and depending into the anchored end portion of this brush head is a well-like formation 8, having an outlet opening 9 in its bottom, the upper portion of the well 8 being flared, 'as at I 0.
The upper end of the shell 5v is externally threaded and over this is* screwed an internally Thelfollower I4`has'a pair of upstanding lugs I6, I6 notched atl their upper ends, as at I'I, these notches serving to receive outstanding formations I3., i8 on spring-detents I9, t9 which atY v their inner and. lower ends are` anchored as at 2D to the rlower portion of the sleeve I2, the upper` portions thereof being bent outwardly and forming'arms 2l which passthrough guide bodies 22 either formed integral with or secured to the cap II.
The outwardly disposed portions. or arms 2I of the springs I9 not only project through open-A ings in. the bodies 22, but outwardly through openings 23at diametrically opposite points on the cap lI, these portions 2I of the springs I9 terminating in small finger engagealole heads 24.
Elongated compression springs 25, 25 are interposed between the bodies 22 and the follower I4,
it being preferable that the bodies 22 and ther follower I 4 be recessed to receive the end convolutions of said springs 25.
Numeral 26 denotes a hand knob having a centralY recess 2l at its under side, into which the upper end of the plunger I3 ts and Where it is.
secured to the .knob 26 as at28.
A coiledL compression spring 29 has its upper convolutions located within the recess 2l, theV` spring being` interposed between the top of the cap II and the knob 26'at the upper end of the recess 2l'.l
Detent means between the knob 26 and the cap I i is provided, inthe :form of a pair of hook members Stlon-thetop ofthe cap II andV a pair of complement'al eyesSI; depending from the bot-` torn sidezoithe knob 2B.
The inner end of the plunger I3 has a reduced valve dening portion 32 adapted to seat within the opening 9 of the well 8, when the eyes 3| and hooks 30 are engaged, and upon referring to Figure 2 it will be seen that the annular wall of the well 8 has guiding engagement with the lower portion of the plunger I3 and directs movement of the valve 32 into the opening 9.
Assuming that the supply of shaving cream A in a cartridge 33 has become exhausted, the cap I I is unscrewed from the shell 5 and as it is withdrawn from the shell the follower I4 and associated operating elements are removed from the shell, the plunger I3 also being drawn from the shell 5. The operator now pushes the follower I 4 towards the cap until the notched ends of the lugs I5 engage the outstanding lugs or teeth I8 of the springs I9, thus holding the follower I4 in retracted position. Further, the hooks 33 are engaged with the eyes 3l by turning movement of the knob 26, as is apparent in Figure 3.
The used cartridge 33 is now removed and a new cartridge of cream inserted.
The structure shown in Figure 3 is now brought to a position over the upper end of the shell 5 (see Figure 4) with the follower I4 fitting inside of the new cartridge wall and against the cream therein. The cap II is now forced downwardly, the valve structure 32 seating in the bottomof the well 8 and this is followed by rotating the cap lI to screw the cap properly on the shell 5.
The knobs 24 can now be pushed inwardly, releasing the outstanding formations I8, I8 from the notches Il of the lugs I6, thus releasing the follower I4 so that the springs 25 force the same against the cream A, thus maintaining the cream under spring force.
When it is desired to impregnate the bristles of the brush with the cream, the operator rotates the knob 26 slightly, so as to disengage the hooks 3D from the eyes 3l whereupon the plunger I3 will be lifted in response to the expansion of the spring 29, permitting the cream A under force to be dispensed through the opening 9 in the bottom of the well 8, to impregna-te the bristles 1, and to the end that by applying to the face, lather can be formed.
While the foregoing description sets forth the invention in specic terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to vwithout departing from the spirit and scope of the invention as claimed hereinafter.
