cream, being of a soft consistency adapted 'A cylindrical reservoir ,10 is formed as the soap receptacle and constitutes .the grip or handle of the brush. The bristles 11V are gripped invzthe usual hard rubber base 12 which `is secured in the upper end of the reservoir 10 thereby eifectually closing "that end. f y

Vlminediately. underfthe base 12' is a disk 13 having a rigid nipple 11i extending upH1 Wardly therefrom, centrally through and terminating slightly above the base 12, within the bristles 11. A passage 15 extends continuously through thedisk and nipple 1e.

A cap 16 is'screuthreadedly engaged to the lower end of the reservoir 10 so as to close the lower end of the reservoir'10. A shaft 17 passes 16 and has a shoulder '18 bearing against the top side of the cap to prevent downward displacement of the .Y shaft 1T, The lower end of the shaft 17 is rigidly secured WithinY a, disk 19 bearing against the under side of the cap 16, and the disk 19 has a diameter slightly larger than the diameter ofthe cap 16, though it may be smaller if desired.

In Fig. 2, the shaft 17 carries a screwof the disk upper end, andthe only nozzle 23 after it is positioned on the nipplel Fig. 8, a vert-ical section of the 'saine modi` A to @mehr Sean' in theV state commonly known ras shaving y y cylinder 10 thereby kthe cylinder and the cal y rotatably through the cap.

A ries a leather facing 22 which'upon being inoistoned bythe soft soap above, swyells and contacts the Walls'of tlie'rese'rvoiry in .a manner to resist its'roti'itionv upon turning'of the shaft 20.

The nipple 1li nozzle il'slipped over its upper endto'eitend down over an enlargement on the .end of the nipple so that the` nozzle 23 maynot slip ofi the nipple 1l unless expressly pulled offby force. The nozzle 28 substantially a short piece of rubber tubingV c lo.sed, at.its @remue frente@ 14 is `through a puncture end which is normally 'closedV on accountof the elasticity of the rubber,

24 being exactly the same Aopening as would be niade in an automobile tire inner tube by running a needle intofit.

Byl properly turning the rdiskll.) .so @as ,to revolve' the shaft 20the piston 21lis carried soap, thereby lsubjectupxvardly against the ing the soap to pressure, and upon sufficientl pressure lbeing created, the soap Willflow' up the passage 15 through the nipple 14, into the nozzle 23 and stretch the rubber nozzle so that the puncture '24 is enlarged to permit the soapL to flow out onto the bristles 11 until the .pressure on the soap is reduced somewhat, when ythe elasticity/of the rubber nozzle 2e sufficiently to overcome pressure. Y

ln practice it requiresbut a slight turn of the handle control disk 19 to cause an 'ejection of just the proper amount of soap, rand the unique construction of the nozzle is such that it effectually shuts off the flow of thersoap sharply and prevents any furthe Vremaining 23 will close'the puncture f Y 10 and The refller vwith if ther discharge until the disk 19 is. further rot-ated. Also in practice, the soap may be furnished in convenient replacing fillers, cylindrical in form, to fit snugly into the reservoir to let the piston 21 work up through the replacing unit.

The structure above described, being that illustrated particularly in Fig. 2, is but one method of accomplishing the feeding of the soap, and many other modifications may be substituted vwithout departing from the spirit of the invention; Two of such modiiications are shown in Figs. 3, 6, 7, and 8.

Referring first to Figs. 3 and 6, the shaft 20in Fig. 2, is replaced by a shaft 25, square in cross-section, and a piston 26 is provided to. screw-threadedly en 'age the cylinder 27. The shaft 25 passes slid-ably through the piston 26 with theresult that upon suitable turning of the disk 19, the shaft 25 being revolved, the piston 26 will likewise be re volved, but being screw-threadedly engaged to the cylinder 27 will tra-vel up or down, axially of the cylinder 27. The cylinder 27 here shown is a refiller soap cylinder having threads 28 rolled into its wall and is snugly carried within the usual cylinder 10. cylinder 27 may be dispensed desired and the threads 28 formed ldirectly in the reservoir wall, as in Figs. 7 and 8. By suchstructure, the piston is positively made to travel axially'of the cylinder does' not depend upon its frictional engagement with the wall ofthe cylinder 10 as first described.

In Athe structure shown in both Figs. 2 and 3, the shafts 2() or 25, must project into the soap, and while this may not be objectionable, the structure shown in Figs. 7 and 8 overcomes this feature. In the structure there shown, the piston 26 edly engaged to the cylinder 10, and in place fof any shaft working through the piston, a

series of links 30 and 31, pivotally secured one to the other der side of the piston and to the shaft 17 respectively, is employed.

By rotating the disk 19, the link system .is l

is screw-thread-V and by the ends to the un` rot-ated to rotate the piston 26 and as the piston 26 travels up the cylinder 10, such links approach thev straight line aXis to follow the piston, and conversely, as the piston iS caused to travel downwardly, the links tend to fold side by side to assume substantially horizontal positions when the piston 26 is in its lowest position. The link system here shown iscomparable to a folding steel rule. lVhile the invention is here described in one particular form, it is obvious that vmany changes may be madein the structural form without departing from the spiritof the invention.

I claim: 1. A soap dispenser having a soap receptacle, screw-threads formed in the internal wall ofrthe receptacle, a piston screw-thread edly engaging said receptacle threads, a Vrotatable member positioned at one end of the receptacle, and a Vmember interconnecting the under side of the piston with the said rotatable member, said interconnecting member being reduced in effective length as said piston moves toward said rotatable member. Y

3. In a dispensing device, a receptacle adapted to hold soap and having internal screw-threads, a piston screw-threadedly engagedin the receptacle, a rotatable member positioned at the' bottom of the receptacle, and a plurality of links pivotally secured one to the other forming a foldable member attached Vby its ends to and between said piston and said rotatable member. 3. in a dispensing device, a receptacle adapted to hold soap and having internal screw-threads, a piston screw-threadedly lengaged in the receptacle, a rotatable member positioned atthe bottom of the'receptacle,
