Referring in detail to the drawings, in Fig. 1 a dispenser for liquid or powdered soap made in accordance I and inwardly corresponding to the taper of the dove-- 2,939,613 V Patented June 7, 196i) 28. The lower body section 26 includes a cylindrical body portion 30 formed with a central bore 32 and closed at its bottom .by awall 34. The'body is formed with a countersunk bore'36 at the top forming an inner annular shoulder 38 in the bed The top of the body portion 30 is open.

The upper body section 28, is cup-shaped forming a socket and includes a side wall 40 anda bottom wall 42 with a tubular extension 44 extending downwardly from the bottom wall and adapted to engage the side of the countersunk portion of the bore of the lower section 26 and to seat on the shoulder 38. The bottom wall 42 is slotted at its center to form a skeleton frame or spider having radial arms 46, with a central hub portion 48 and with slots '50 between the arms. An integral lug 52 depends from the hub portion 48 into the tubular extension 44. A cork washer 54 is'seated on the bottom wall 42 with itsopening communicating with the slots in said bottom wall.

A connecting arm 58 is formed integrally with the body portion 30 of the lower section 26 of the fitting and extends outwardly and upwardly therefrom in an inclined direction. The arm extends upwardly to a point level with the top of the upper body section 28 and terminates in-a verticallydisposed plate member 60 of dovetail cross-sectiomas shown in Figs. 4 and 8. The platemember 60 extends downwardly to a point substantially. level with the bottom :wall 34 of the lower body section 26 and its long side edges taper slightly downwardly and inwardly sothat .the top of the plate is slightly wider than the bottomthereof.

The extending arm 58 on the fitting permits ready mounting of the. dispenser on a vertical supporting surface such as -a wall or the like and for this purpose the invention contemplates the provision of the bracket 16 to be fastene'dto such a supporting surface. The bracket 16- comprises a plastic plate 62 enlarged along two opposed side edges thereof as indicated. at' 64. The enlargements are for-medjwith undercut dovetail slots 66 extendingtherealong, the slots tapering downwardly tailed side edgesf168 of the plate ,60 of the fitting 14. A pair of, countersunk aligned holes 70 are formed in the centergof plate 62 to receive fastening elements for fastening .the bracket to the supporting surface or-walL.

The valve mechanism for controlling the passageof the liquid'orpowdered soap through and outwardlyof the fitting 14 onto the hand for ;u se,includes a plastic plunger 72' comprising an elongated plastic rod 74 substantially cylindrical, extending through a tubulariextension 76 depending from the bottom wall 34 of the lower section 26 of the fitting. The central opening in the tubular extension communicates with a central opening 78 formed in the bottom wall 34. The rod- 74 is formed with spaced grooves or flutes 80 extending from and intersecting one end of the rod, the outer end as viewed in Fig. 3, to a point remote from the other end thereof. Three of such grooves 80 are shown, extending along the central opening in the extension 76 and the opening 78 in the bottom wall 34.

Adjacent its other or inner end as viewed in Fig. 3, the rod is formed with an annular flange and carried by the rod below the flange 90 and contacting therewith is a sealing plastic washer 92 adapted to seal the opening 78 in the bottom wall 34 of the lower section 26. A compression spring 94 is interposed between the rod 74 and the hub portion 48 of the bottom wall 42 of the upper section, one end of the spring being seated the opening 78 in the bottom wall 34 of the lower section 26 of the fitting. In this sealing position, the rod 74 protrudes outwardly of the extension 76 so that it can be readily pushed inwardly by the finger of the hand of the user. A downwardly depending lug 94 on the bottom end of the extension 76 is adapted to engage the finger to indicate that the desired limit of upward movement of the finger of the user has been reached in order to prevent displacement of the valve parts.

In use, the bracket 16 is fastened to a vertical supporting surface such as a wall or the like. The plate 611 is slid downwardly along the slots 66 in the bracket until the plate is locked in the position shown in Fig. 3. A bottle 13 filled with liquid or powdered soap is inverted and its neck 20 screwed onto the upper section 238 of the fitting 14 until its annular bead 24'seats on the upper edge of said upper section. In this position, the neck of the bottle will rest on and be sealed by the cork washer 54. When it is desired to dispense soap, the plunger rod 74 is pushed upwardly by the finger of the user against the action of the spring. 94 thereby carrying the sealing washer 92 oif its seat and away from the opening 78 in the bottom wall 34 of the lower section 26 of the fitting whereby communication is established between the bore 32 in' the fitting and the central opening 78 in the extension 76 on the lower section 26 and soap is permitted to fiow by gravity through the grooves or flutes 80 formed in the rod 74 through the central opening in the extension 76 and outwardly thereof onto the hands of the user or onto any other surface desired. When the finger of the user presses the rod 74' upwardly to open position, it engages the depending lug 94 on the extension 76 which serves as a stop to warn and prevent further upward travel of the finger.

In the modification of the invention shown in Figs. 9 and 10, the extending arm 58 may be fastened directly to the vertical supporting surface thereby eliminating the necessitvfor the plate 60 and bracket 16 used in the form of Fig. 1. For this purpose, the arm 58 is formed with an elongated slot 98 adjacent its free end, the slot being formed with a circular countersunk portion 100 to receive the head of the fastening element. The free end of the arm is also formed with a slightly beveled portion 102 slanting in one direction and with an opposed beveled portion 104 slanting in the opposite direction. The beveled portion 102 permits the arm to be positioned against a vertical supporting surface in such a condition that the fitting and supported bottle are disposed vertically; The fastening element will extend through the slot '98 at an angle to the horizontal and the beveled portion 104 permits the tool to drive the fastening element home.

In all other respects, the form of invention shown in Figs. 9 and 10 is similar to the form of Figs. 1-8 and 4 similar reference numerals are used to indicate similar parts throughout.
