POWDER-DISPENSING DEVICE Application filed December 26, 1930. Serial ITO/504,789. I

My invention relates to powder-dispensing devices intended for general use but especially well adapted for dispensing powdered soap and has for its object the provision of such a device that is simple in construction, easy to operate, positive in its action, and when closed, protects the contents of the container from dust, dirt and moisture and prevents waste of the powder during the dispensing thereof. Moisture in the container often causes the powder to become lumpy and thus interferes with the operation of the device. I

To the above end, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawing, which illustrates the invention, like characters indicate like parts throughout the several views.

Referring to the drawing:

Fig. 1 isa view partly in side elevation and partly in central vertical section; and

Fig. 2 is a View in transverse section taken on the line 2-2 of Fig. 1.

The numeral 0 indicates a powder-dispensing cylindrical container having a dis placeable cover 1 and a bottom 5 in the form of an inverted truncated cone with a gravity feed discharge opening 6 at its apex.

Within the container 3 is a frame 7 formed from a single metal strap bent to form a pair of diametrically opposite side members, which bear against the sides of said container, and upper and lower cross-tie members. This frame 7 is detachably but rigidly secured to the container 3 by screws 8. The lower end portions of the side members of the frame 7 are in converging relation and rest on the bottom of the container 3 with the lower cross-tie member within the bottom of the container.

The passageway 6 is normally closed by a valve 9 which is below the apex of the bottom of the container 3 and arranged to seat thereon when closed. This valve 9 has at its axis an upwardly projecting square stem10 .which extends axiallyinto the container 3 through the passageway 6 andapertures' in the upper and lower members of the frame I? :5 with freedom for compound endwise and rotary. movement. A coiled spring ,11 encircling the valve stem 10,between the crosstie members of the frame/7, is anchored at its lower end of the lowermost of said members @155 and attached at its upper end tothe stem 10. This stem 10 also extends axially through a relatively. fixed depending sleeve '12 on the upper cross-tie member ofthe frame'7 with freedom for endwise andturning move- 3 ments Formed in the sleeve ,12 is a-spiral groove or channel 13 and cooperating therewith is a fixed cam stud 14 on the stem 10. The valve 9 is constructed'andarranged to open and close by a compound-endwise and 1,65

rotary movement imparted thereto by the cam device 13-14. The spring'llnormallyholds the valve 9 closed and which valve is pro vided at its lower'end with a radially projecting handle 15 by which it may be turned 10 .to cause the cam= device1314 to vmove the valve 9 axially downward to open the same. A depending spout 16 is secured to the bot- .tom of the container 3 in axial alignmentwith .the passageway 6 and radially spacedtherefrom and the valve 9. This spout 16 terminates above the handle 15 so as to not inter- 'ferevwith the action thereof. The top of the valve 9, which closes the passageway 6, is

spherical and facilitates the escape of the F powder-from the'container 3 through the discharge passageway 6 when-said valve is open.

A second valve 17 on thevalve stem 10 and 1 in the form of a disk is vertically spaced above; the main valve This valve 17 isconstructed 3 and arranged to open and close in reverse 7 y comprisingtwo pairs of circumferentially spaced rods that project upward parallel to the walls of the bottom of the'container 3 and spaced therefrom. The two' pairs of agitator rods 18 are secured at their lower ends to the valve-stem at vertically spaced points and the valve 17 is held thereby against axial movement on said stem. Formed in the pe riphery of the valve 17 are V-shaped notches 19 through which the agitator rods 18 of the lower pair extend.

Any suitable separable fastener may be provided formounting the container on a Wall 4 or other relatively fixed support.

ieau'se-the c'am device'1314to close the valve From the above description it is evident that by means of the handle'15 the valve9, and hence its stem 10, may be turned iniafdi-n rection to cause the cam device 1314"to" positively move the valve 9,-down-ward'iand open the same to allow the powder between wise and turning movements, a cam pin on the valve stem extending into the cam slot,

the valves 9 and 17 to flow through 'the 'passageway 6 and be directed by the spou'tdownw'ard into a handheldjthereunden At the completion of the opening move- -ment of the valve '9 the valve 17 will close' and prevent further flow of powder from thereabove. I Upon releasing the handle 1'5 the spring 11, which was-tensioned by the openingof the valve 9, will lift said valve and i'a't'the same time turn the same and thereby 9zan'd open the valve I During the rotation of-the valve '9 the agiita'tor rods .18 are turned about the axis ofthe stem 10 and "thereby keep the powder Iloose ;so that the same will. freely flow between the bottdmofythe container 3fand the valve 117 and over the valve 9 and through the dis-V charge passagewayfi.
