676701??- HA MSON BY y A TTORNE'Y Patented Sept. 11, 1934 DISPENSER SigvortHanson, Racine, whl, assignor to Racine Dispenser & Manufacturing Company, Racine,

Wis., a corporation Application December 26, 1933, Serial No. 703,889 7 Claims. (01. 221-108) My invention relates to improvements in dispensers designed to discharge powdered material, particularly malted milk, my object being to simfi plify the construction and operation of such dispensers so that the actuating parts thereof con-' tacting with the material may be readily removed, cleansed and reassembled, and a predetermined portion of material selected from the mass contained therein and discharged into a vessel, such as a glass, when so engaging the latter with means controlling a valve or cover to open the. discharge outlet of the dispenser and which outlet'will be automatically closed upon the removal of the vessel, as will hereinafter more 'fully appear.

In the accompanying drawings, forming par-t hereof, Figures 1 and 2 arefront and side elevations, respectively, of a dispenser embodying my improvements; Fig. 3, an elevation showing the dispens'er parts disassembled; Figs. 4, 5 and 6,'re-

spectively, are plan views of an agitator, a shield, and a measuring wheel, which I employ; Fig. '7, a detail as seen when looking upwardly from the arrows '7-"7 in Fig. 8; Fig. 8, a longitudinal vertical sectional view of the dispenser; Fig. 9, a detail as seen when looking in the direction of the arrows 9-9 in Fig. 8; and Fig. 10 is a detail sectional view taken on the dotted line 1010 in Fig. 8.

In said'drawings the portions marked 5 indicate the body of the dispenser, upon which is mounted a frame fi'supporting the actuating parts and the material container 'Z'made of glass or other suitable material, which body and frame are connected by bolts 8 to a base 9 having suitable footrests, as 10.

In the frame 6, having an outlet 6', a shaft 11 is mounted and upon which I position a measuring wheel 12 having blades 13 and a tapered hub vided for the shield 1: between the wheel and.

agitator so that the latter elements may freely rotate about the. stationary shield.

Beneath the measuring-wheel 12 and keyed or 14 detachably pinned to the shaft, at 15. Aboveotherwise secured to shaft 11 is a ratchet-wheel 27 positioned between ratchet-arm members 28, 28', carrying a pawl 29 controlled by a spring 30,

which ratchet engages wheel 2'7, as indicated in Fig. 7, the opposite end of the arm including a segmental rack 31 engaging a rack-bar 32 secured to' an arm 33 connected to a. valve opener 34 having a vessel support 35 pivotally connected,

' at 3,6, 'to the casing or body of the dispenser. At

the upper end of theopener is a valve 38, pivotally connectedat 39 to the opener 34, and which a valve 38, as shown in Fig. 8, normally closes the outlet 6' and excludes moisture therefrom.

When it is desired to charge a vessel with material from the container 7, the vessel, as A, is placed as shown by dotted lines in Fig. 2, upon the support 35, Fig. 8, and with the opener 34 tilted rearwardly within the dispenser body, which action causes the rack-bar 32, engaged with segmental rack 31, to move ratchet-arm 28 and simultaneously with ,such movement the ratchet-wheel 27 and the measuring-wheel '12 are rotated so that the space between the blades 13 registers with the discharge outlet 6, the pawl 29 on the ratchet-arm actuating the ratchetwheel to revolve the wheel as well as the agitator 23, the rotating measuring wheel 12 carrying a charge of material under shield member 19 to the discharge outlet 6' to be deposited in the vessel.

When the opener 34 is being tilted to the position indicated by dotted lines, Fig. 8, the valve 38 carried by said opener is gradually released from the outlet 6' until it assumes the vertical plane indicated so that, the entire charge in the outlet will be deposited in the vessel. When the valve is completely removed from the outlet further movement of the opener is. prevented by a suitable stop, as 40 for example, which at the limit of the inward movement of the opener contacts the base 9. After charging the vessel and as it is being removed it is returned to the dotted line position, Fig. 2, and the opener and parts associated therewithlikewise are returned to the full line position shown in-Fig. 8, and consequently the ratchet-arm 28 and associated parts are returned to normal'position for the next operation, which as will be understobd, may be repeatedly performed in the manner described.

,In the operation of depositinga charge of ma-. trial in a vessel it will be understood that the "measuring wheel .12 is so timed that a pair of its blades 13, carrying a predetermined portion of material between them. is moved by the action flowing from the container '7 above is filling the spaces between the remaining blades as it is being treated by the rotating agitator 23, the fingers 24 of which, passing closely over the knife edges 18 of the shield member 18, cooperate therewith in pulverizing the material before the same is moved by the wheel 12 around under the shield 19 to be d scharged into the vessel, and which shield prevents surplus material from entering the outlet until moved thereover, and in which manner each charge will be uniform, as the spaces between the wheel blades are of equal dimensions. In Fig. 3 it will be noted that the container is preferably an open-ended jar mounted inthe frame 6, Fig. 1, and having a cover 7' to enclose the material placed therein, which flows into the rotating parts to be agitated, pulverized, and ap-,

portioned by the measuring-wheel into uniform quantities to be discharged into and through the outlet 6 upon performing the operation described, the conical formation of hub 23 directing the material into the spaces of said wheel 12. The rotatable elements are pinned together in assembled condition about the shaft 11 in the simple manner shown and described, and, as will be understood by reference to Fig. 3, each may be detached and removed for cleansing and as readily inserted and assembled, and by reference to Fig. 8 it will be seen that when vthe pin 15 is withdrawn from shaft 11 said shaft and associated parts can be readily removed for inspection or repair.
