provide the piston, which operatesin the handle for expelling therefrom the material which is to be dispensed, with means for preventing the escape of any portion of the Said material between the saidV piston and the means for causing movementthereof longitudinally of thesaid handle.

OtherV objects and advantages of my invention will be pointed out particularly and referred to in the detailed description thereof which follows or will be apparent from said description. f

In order that my inventionmay be more readily comprehended and its commercial Vand practical uses more fully appreciated,

reference may be had to the accompanying drawing in which I have illust-rated one- Vform of aa convenient embodiment thereof.

Various changes may "bemade in the details of construction without 'departingvv from. the' 'principles of my invention.-

In the drawing: Figure 1 is a longitudinal sectionalvievv of a fountain shaving brush -in which the dispensing portion is constructed in accordance with my invention;

Fig. 2 is a transverse sectional view taken on the line 2 2 of Fig. 1; and

Fig. 3 is a sectionalA ew taken onthe lline 3:-3 of Fig. and showing a detail ofcony 'structioin p n Referring to the drawing, 1" designates V'la 'hollow handle which.v also constitutes the reservoir for holding the material tofbe disl pensed. The outer rear end portion ofthe said handle is enlarged as indicated at2 .for a purpose to be hereinafter indicated-andjis closed, as indicated atf-'the closure' in 'fthe' construction .shown 'being integralA with the body of the handle. vHoweverrthis need not ofa separate cap sealed or otherwise secured The inner end of the handle- 1 .is closedfby 4 having a Hange 5 whichV isscrew "The inner or rear ends of the hairs consti- Vend of which isbent and finished in the form v'f an annular Y.enlargement or head, as inbe the case, because the closure may consist l The head 8 is adapted to have detachable.

screw threaded connection with the screw threaded annular flange 9a of the member 10. The latter is secured at 11 to a shoulder formed at the inner rear end of a tubular member 12 the outer forward end of which is provided with an o ening 13 which opening is adapted to be c osed by the lower end 14 of a discharge tube leading from terior of the handle 1. The portion 15 of the said tube which extends into the tubular member 12 is relatively small as compared with the screw threaded ortion 16 of the said tube which is situate in the handle 1.

Theportions 15 and 16 may be constructed.

` which is situated in the annular space within the enlarged portion 20' surrounding the portion l5 of the discharge tube or passageway.

A gland 24 which has screw threaded connection with interior threads -upon the enlarged portion 20 is adapted to compress and hold the packing material 21 securely and tightly in place against a portion of the exterior surface of the part 15 of the discharge tube or passageway. It will be observed that the discharge tube is provided with openings at 25 for the discharge of the material 26 therefrom. After the discharge of the materi-al from these openings it escapes through the opening 13 to the brush 7 30 designates a member which is perma-A nently and ixedly or rigidly secured to the tubular passageway for conveying material `to he dispensed from the reservoir. The

member 30 is provided with an' enlarged for# wardly extending portion which is hollowed out -as indicated to form a chamber 32,-the hollowing out of the same, forming what may be described or defined as a skirt 33. The skirt 33 is provided with a laterally extending flange 34 as shown. The enlarged portion 20 together withthe gland 24 telescopically project into the chamber 32 within the skirt 33. j

35 designates an annular spacmg member reduced at its upper end -as shown to form a shoulder 36. The forward end ofthean'l nular member 35 rests against the member l() while the Arear inner end thereof rests against the inner surface of a. member 40, the

y latter being provided with a'lange 40L which has screw threaded connection with the innerrear end of an annular covering member The forward end of the annular member 41 is smooth and extends around and covers and is secured to the screw threaded flange 9a of the member 10.

The member 40 is provided with a central.

substantially square opening 42 in which the intermediate portion of the member 30 is the in-l -but cannot rotaie with respect thereto.

The closing cap member 4 is'provided with a central opening as indicated at 45 through which the rear end portion of the member 30 extends,V the said member being provided with a shoulder against which the forward side of said member 4 surrounding the opening 45p-is seated. The cap member 4 is rotatably secured in position upon the member 30 by a nut 46 which has screw threaded engagement with a reduced portion 47 of the member' 30.

The member 40- is provided at intervals with depressed inclined portions 50 which constitute cams for coperating with correspondingly shaped and formed cam projections 51 upon vthe forward side of the handle closing cap 4. It will be observed that in the present construction I have shown two cam surfaces 50 and also two vcoperating cam projections 51.` It will be understood, however, that a greater number of such cam acting parts may be provided if desired, depending upon the amount of material it is desired to discharge at intervals from-the interior of the handle.

It will be noted that 'I have provided a coil spring 56 which is situated in the annular space between thespacing member 35 and the skirt 33. The forward end of this spring is seated against the annular flange 34 while the rear end thereof is seated against vthe shoulder 36 formed at the rear upperv end portion vof the annular spacing member It will be observed that 'when once screwed in lpositionthe portions 10, 40 and 41 are fixed with respect to each other, that is to say, immovable longitudinally.

The screw threaded flange 40a ofthe member 40,Y as well as the screw threaded flange 5 of the cap 4 when the parts are in operative position with the cam projections 51 seated against the cam surfaces 50, is covered and protected by means of an annular covering and protecting member54. The said member 54 is provided with a short inturned flange 55 which is seated against the outer periphery of the member 41 at ay point just forward of the forward edge of the flange 40a'. Said member 54- also .provided with an annular inwardly extending proj ection- 56 which isvsituated just in rear of the .outer peripheral edge of the member 40. In this 62 which contact with and press against the said disk at its inner annular rear edge with an inwardly extending annular flange portion 64 which extends over the rear edge of the hub 63 and cont-acts vfirmly with .and against the screw' threaded portion 16 so as to prevent the escape -of any of the material 26 from the handle l between the screw threaded portion 16 and the hub 61.

Assuming that the handle is provided with a supply of liquid, semi-liquid or plastic material, such as soap, 26, as indicated in Fig. 1 of the drawing, the device will be operated to cause a discharge of the quantity of material .desired by holding in one hand the portion 41 which,togethr with the parts connected therewith, may be termedthe body portion of the brush-holding section, and taking hold of the handle 1 with the other hand and turning the saine together with the cap 4 secured to the inner forward end thereof to the right in the direction in which the hands of a watch turn. Such turning movement causes the cam projections 51 to slide upwardly upon the cam surfaces 50 so as to cause a longitudinal movement of `the handle 1, the cap 4 and the discharge tube consisting of the parts 15 and 16. Such movement lcauses disengagement of the inner forward end 14 of the part 15 from the edges of the opening 13 so that the latter is opened.;

By reason of the friction between the spring fin ers 62 and the disk y62 with the interior o the handle 1, it will be understood that, the piston which comprises the members and 62 rotates with the said handle and that in consequence thereof it moves longitudinally lin said, handle toward the rear thereof simultaneously with the rotatory' and longitudinal movement of the handle. Such rearward longitudinal movements of the handle 1 and the discharge tube and the part 30 secured thereto is in opposition tothe pressure exerted by the spring 56.

Consequently as soon as the handle 1` has been turned sufficiently to carry the cam projections 51 through a halfvrevolution they will again move into engagement with the cams 50 under the influence of the spring 56 which -at such time causes longitudinal forward movement of the part l, the discharge tube and the part 30 secured to the latter, so that the opening 13 is closed by the forward pointed end 14 of the said tube.

When the plastic material has been driven from the handle 1 by the rear longitudinal movement of the piston the elastic'disk62"1 will be found to occupy the space formed by the enlargement 2 of the handle 1. In plac ing or inserting the disk 62' in the forward open end of the part 1 b'efore lthe same is closed bythe closing cap 4, it is compressed, consequently when it is moved into the enlarged portion 2 of thehandle 1 it expands and cannot readily be removed therefrom.

The idea of providing a construction of handle having means to prevent the ready removal of the disk 62a after the material has been emptied is to prevent the handle from being used a second time.' It is the purpose that the material, such as soap, to be dispensed shall vbe placed in a handle such as the handle l'and the inner forward; end

thereof closed by means of a new elastic disk 62a which handle may then be used and substituted fora handle 1 from which all of the soap material has been discharged,"such used handle being thrown away. i
