6 Claims.

In close proximity to its bottom end, the cylindrical wall of the container is provided with a circular opening B in which is fitted and secured by soldering or other means the axial flange I4 of a cup-shaped sheet metal housing IS.

The front or transverse wall l6 of the housing is provided with a. central opening I! and with a front bearing 18 composed of a number of concavo-convex washers soldered together and to consistency such as mechanics paste soap for an 7 example, functions to break up solid masses of soap and promote a plastic condition thereof, as

well as feed the soap in the container to a zone thereof from which the *soapis dispensed, all in syn'chronism with, and operation by the dispensing mechanism of the dispenser, whereby to insure efficient and accurate dispensing of the contents from the container.

A further object of the invention is to provide a device embodying extremely simple means by' which a container can be. detachably secured to a support in various rotatively adjusted positions, all without the need for tools or for any extraneous fastening means.

With these and other objects in view, the invention resides in the combinations and arrange- Figure 3 is a plan sectional view taken on the line 3-3 of'Figure 1; Figure 4 is a-fragmentary longitudinal sectional view of the lower portionof the dispenser;

Figures 5 and 6 are sectional views taken, re-

spectively, on the lines 5-5 and '6--5 of Figure 4; 7

Figures '7 and 8 are fragmentary detail sectional views taken, respectively, on the lines |--'l and 88 of Figure 6.

Referring specifically to the drawings; the in vention, in its present embodiment, comprises a cylindrical container ID of sheet metal having a closed bottom end II and an open upper end adapted to be closed by a friction cover l2 (Figure 1).

said front wall in co-axial relation to the opening 11. A. rear bearing 19- in the form of a U-shaped strip of metal having an opening 20 in one branch, has itsother branch welded or otherwise secured to-the cylindrical wall of the container H1- at a location diametrically opposed to the opening ll. 7

A screw conveyor is composed of a shaft 26 journaled in the bearings l8. and I9 and having a crank handle 21 at its outerendby which the shaft can be rotated. The screw of the conveyor 25 comprises a number of sheet metal disks each of whichis provided with a central opening receiving the shaft 26 and is split radially and,

pulled. into. helical formas shown in Figures 3 and 4.. Adjacent disks are welded together at their split. edges to: form a continuous helix, and are reinforced so as to be rigid, by stiffening bars 28 which latter are welded to the disks and to the shaftzt. I

The front wall [6 of the housing i5 is provided eccentrically with an arcuate shaped discharge port 30 controlled by a cutoff or valve member 3 l in the form of a segmental plate having a central opening 32 formed by punching a pronged hub 33 laterally from the plane of the plate, which hub is welded to the shaft.

A regulator member 35 in the form of a sheet metal disk has a central opening freely receiving the shaft 26, to mount the disk snugly between the'front wall lb" of the housing l5 and the valve member 3| for rotational adjustment.

The regulator member 35- has an arcuate slot 36 adapted to register with and vary the effective size of the port 30 in response to rotational adjustment of the regulator member by means of a suitable sharp pointed instrument 3'! .(Figure 8) whichcan be inserted into a perforation 38 formed in the regulator member adjacent one end of the slot 36, by punching through the member to leave a burr of sufiicient'height on the outer side of the member to provide a stop 39. This stop limits rotational adjustment of the regulator member in one direction by engagement with the wall of theport Silas shown in Figure 8 the adjustment of the regulator member in the opposite direction being limited by engagement of the pointed end of the instrument with the edge of the port 30.

An arcuate series of radially arranged notches 40 is pressed into the front wall 16 from the inner side thereof for coaction with a radial projection 4| pressed into the regulator member 35 from the inner side thereof, in releasably retaining the regulator member in any one of several positions of rotational adjustment.

An agitator 45 for operating upon the contents of the material in the container 10 comprises a generally circular wire frame 46 of somewhat smaller diameter than the internal diameter of the container. Secured by welding or other means to the frame at diametrically opposed points are bearings 41 in the form of metal Washers receiving aXleor trunnion-forming pins 48 welded to the inside of the container to mount the agitator therein immediately above the conveyor 25 for oscillatory movement about an axis parallel to the axis of the conveyor.

The agitator 45 also includes longitudinal bars Q9 and a transverse bar 50, the former spanning segmental portions of the frame 46 at opposite sides of and in parallelism with the axis of the agitator. The transverse bar 50 connects the bars 59 at one end thereof and co-acts with the frame 45 in supporting a-yoke 5| in depending position and at a right angle relative to the axis of the agitator for engagement by a crank 52 bent out of the shaft 25, whereby upon rotation of the shaft, oscillatory motion will be imparted to the agitator.

The container H3 is adapted to be secured to a suitable vertical support by brackets 55 each constructed of a single length of wire to provide an open loop 56 adapted to embrace the container and terminating at one end in an attaching bar 5'1, the ends of which are provided with return bends 53 to define slots 59 adapted to receive screws 60 to secure the bracket to a support.

The free end of the loop 55 is laterally bent to provide a holding notch Bi and a latching notch 62 adapted to co-act with a keeper notch 53 formed on the bar 51, in respectively holding the loop 56 in an expanded position to freely receive the container and a constricted position to tightly embrace and rigidly support the container. In practice, two of the brackets 55 are employed and are spaced on a support to co-act with the container adjacent its ends as shown in Figure l.

The operation of the invention is as follows:

Let it be assumed that a quantity of a fluid substance such as paste soap has been supplied to the container, and that the regulator member 35 has been adjusted to a selected position. Upon rotating the handle 2'! in a clockwise direction as viewed in Figures 1, and 6, the feeding action of the conveyor 25 will force soap through the port 30 during the portion of a revolution of the shaft 26 in Which the valve member 3i opens the port.

As the agitator is being oscillated between the extreme positions shown in broken lines in Fi ure 5, during a single revolution of the shaft 26, the frame 46 and the bars 49 of the agitator 55 undercut the mass of soap so as to work the latter and tend to promote its plasticity in counteraction to the tendency of the soap to become more solid with an attending failure to gravitate in the container. The downward and inward direction of motion of the frame 46 and bars 49 urges the mass of soap into the operating zone of the conveyor so as to insure that the latter will be fully supplied with soap for dispensing in response to the feeding action of the conveyor upon the soap.
