2 Claims.

ing mechanism, whereby to provide what is be-` lieved to be a more efcient and superior brush construction.

More specifically, novelty is predicated upon a handle which is fashioned to provide a reservoir for the cream, there being provided therein a discharge orifice to feed the cream into contact With the bristles, and a slide rod being provided, one end of the rod fitting into the ori- L.

fice to function as a valve and the other end of the rod being provided with a convenient hand-grip to facilitate opening and closing the valve.

In addition to the above it is an objective, l

structurally speaking, to line the cream chamber of the handle with a cylinder which functions to accommodate the cream expressing plunger and houses the feed screw for said plunger, said feed screw being operatively connected with a hand knob and said knob being fashioned to provide fluid-tight operating connection with an adjacent end portion of the cylindrical liner.

Other and more explicit features and advantages will become more readily apparent from the following description and the accompanying illustrative drawings.

In the drawings, wherein like numerals are employed to designate like parts throughout the views:

Figure 1 is a view in elevation, with a portion broken away, showing a fountain or dispensing type shaving brush constructed in accordance with the principles of this invention. l

Figure 2 is a longitudinal sectional view, with parts in elevation, taken approximately on the A plane of the line 2-2 of Figure 1, looking in the direction of the arrows.

Figure 3 is a horizontal section on the line 3-3 of Figure 2, looking in the direction of the arrows.

Figure 4 is a fragmentary View in section and elevation based on Figure 2 and showing the valve in open position.

Figure 5 is an exaggerated fragmentary sectional view on the plane of the line 5--5 of Figure 2, looking in the direction of the arrows.

Referring to the drawings by distinguishing reference numerals and accompanying lead lines, the handle, as a unit, is denoted by the numeral l and is of appropriate dimensions, shape and material. It is here shown with a portion of appropriate external bulbous-like form as at 8 for convenient grasping by the users hand. The numeral` 9 denotes an appropriate shoulder. Since the handle is essentially hollow the hollowed portion I!) provides a socket, said socket being in communication with the discharge crice or passage ll by Way of a recess or well I2, said passage opening into the bristles I3. There is a metal lining, which may be described as a cylinder, the same being denoted by the numeral I4 and fitting into the essential portion of the stated socket and this cooperates with the socket I0 and the rest of the brush to provide a reservoir or container for the shaving cream (not shown). The cylinder is provided with diametrically opposite internal guide ribs I5 as shown in Figures 2 and 3.

I next call attention to the plunger, functioning as the expressingvmeans. This is characterized by a suitably shaped and marginally knurled knob I6, said knob having a reduced adapter I1 which defines an annular groove into which the constricted inbent end portion I8 of the cylinder is fitted to provide the desired swivel and duid-tight connection between the knob and cylinder as shown in Figure 2.

The numeral I9 denotes a tubular externally screw threaded feed screw having its upper end (Fig. 2) embedded and anchored as at 2|] in the central portion of the turnable knob. A disk-like cream expressing plunger or disk 2l is threaded on the feed screw and has diametrically opposite notches slidably keyed on the keying ribs I5. Thus, as the feed screw is turned through the motion of the knob, the plunger is worked back and forth in the reservoir or chamber in an obvious manner, the plunger sliding but not turning. The knob is provided with a passage, as at 22 and this serves to accommodate the coacting portion of a valve rod 23. The valve rod is slidable through the passage and the projecting end is provided with a finger grip, as: at 24 which is operable independently of the knob I6. The valve rod has its valving or tip end (see Figure 4) 25 arranged to operate through the well and to project into the discharge orifice or passage II. The adjacent portion of the valve rod has a slot 26 formed therein which slot serves ing the passage, allowing the feed screw and plunger to come into action to force cream from the reservoir into the brush bristlesffrin anob- Vious manner.

The hollow brush handle providesfa fmetal.. lined socket for the cream to-be dispensed and ,Y

one end of the cylinder is fashioned into a closure having swivel duid-tight connection with thecoz-J` acting adapter portion oi the knob. Thus, the

knob is freely rotatablein relation to the'handle to obtain .thefdesired feedfscrew and plunging or ejector. results:y The, valve is .an independent' element and is primarilykeyed inY place to-avoidv.

loss rather; than for. the purpose of pinningit to the feed screvvrfor. rotationin unison .with the latter.A

It is -necessaryto separably connect the lining with the'rhandle and therefore the liningradjacentr thezswivel connection isfprovidedY with screw threadsL at y-28 and these-are screwed ,into-internal.

screw .threads l 29 provided: in `-the vsocket portion of-,the handle; Thus,the two parts Amay besepaf, ratedwto` permit the. cylinder Ato -be Vchargedfvvith cream Yand then assembled inthebrush for suitable. .operational results A. careful consideration of the i' foregoing descriptionin.conjunction with`l` the `invention as Y illustrated -inthedrawings willenablethe reader to Vobtain a'clear understandingand impression of the alleged features of. merit ,andr novelty,` suf,-` cientto clarify the` constructionoith invention ashereinafter claimed.

as new is:

1. yA force-feed dispensingftype shaving brush of ftheclass shown and described4 .comprising/:av hollow handle closed at one end ,and provided in said end with a central .dischargepassage andanV accompanyinglwell in alignment with ,said .pas-

2. Afforcef-feed dispensing assembly forY insertion in the socket of a hollow shaving brush handle comprising an open-ended cylinder, one end., of the cylinder being constricted in diameter and providing a ange and the adjacent end p0rtion .beingscrew-threaded, a knob provided with a reduced adapter tted rotatably into the cylindenatheperipheral. edgeportion of said adapter beinggrooved and the iiange conforming in shape and size. to said. adapter and iitting into Vsaid groove and serving to swivelly join the knob to the. cylinder, saidknob being provided with a hollow Yfeedscrew mounted, concentrically for,`
