DISPENSER.

My invention relates to dispensers and has a number of objects and advantages in view.

The dispenser of my invention is of particular service in delivering measured quantities of malted milk in dry form, although it is not to be limited to such use.

A dispenser constructed in accordance with one embodiment lof my invention includes a container having a horizontal bottom wall formed with'an upright discharge 4opening therethrough, a horizontal closure plate for said opening located below and engaging the container bottom, a horizontal measuring wheel above and in close proximity to the closure bottom and having teeth deining a succession of pockets communicable. in sequence, with the interior of the container and the discharge opening, and mechanism coupling said measuring wheel and closure and having one portion connected with and serving to move the measuring wheel horizontally in a uniform direction and another portion connected with said closure and serving to move this closure horizontally in an opening direction as each lled pocket is moved into register with said discharge opening and to thereafter move the closure in a closing direction. A dispenser thus constructed has its delivering mechanism and the closure for its discharge opening very compactly arranged so that the length of travel of any measured quantity of its contents undergoing discharge is reduced to a minimum within the structure of the dispenser, a characteristic which is especially important in dispensing malted milk which so readily absorbs moisture from the external air.

In accordance with another feature of my invent-ion, a swinging arm is coupled with the plate to turn it to its opened and closed positions. This arm is upwardly springpressed against the plate and there is a connection between the plate and arm that is in register with the discharge opening when the plate is closed and which connection is formed to permit universal swinging movement of the plate with reference to the arm to enable the plate to have full engagement with the margin of the discharge opening so that the opening is thoroughly sealed against the admission of moisture when the plate is in closed position. To prevent any of the container contents from adhering to the bottom of the container in the region of V1926. `serial No 107,071.

with to effect one measurement of the mate-l rial being discharged and movable away from the plane of rotary movement of the teeth to effect another measurement.

I will explain my invention more fully by reference to the accompanying drawings in which Fig. l is a side view of a dispenser as I preferably construct it; Fig. 2 is a plan view of the base portion of the dispenser, the displaceable part of the container being removed; Fig. 3 is a sectional view on line 3--3 of Fig. 2, the lower part of the displaceable part of the container being also illust-rated in this figure; Fig. 4 is a sectional view on line 4-*4 of Fig. 5; Fig. 5 is a bottom view of the dispenser as it appears when removed from the supporting base that is shown in Fig. 1; Fig. 6 is a perspective view of a part of the structure; Fig. 7 is a perspective view of the closure plate for the discharge opening and a portion of the operating arm therefor; Fig. 8 is a sectional view on line 8 8 of Fig. 5; and Fig. 9 is a perspective view of a portion of the structure which supports the removable container.

The upright cylindrical container 1 has a discharge opening 2 in its bottom wall 3. This opening has a closure in the form of an arcuate horizontal spring plate 4 carried on the exterior of the container upon an arm 5 through the intermediation of a pin 6 desrably carried by the plate 4, the lower end of the pin being rounded, and there received in a. socket 7 formed in the top side of the arm. The plate has st-irrups 4 that embrace the arm whereby the arm may move the plate. The arm is pressed upwardly against the pin by means of a coiled spring 8 which presses upwardly against the arm.v This spring desirably surrounds the shaft 5 being bottomed upon a washer 52 that is held in place by a nut 53.

A flat horizontal measuring wheel 9 is journaled upon the shaft 5. This wheel is formed with teeth 10, preferably in the form of blades, which define a circular succession of pockets 11 adapted to be vsuccessively placed in register with the discharge opening. This wheel is within the container and turns upon the bottoml wall thereof, the teeth ends closely approaching the cylindrical wall of the container in order that the quantities in the pockets may be accurately measured in conjunction with a levelling arcuate plate 12 carried by and withinV the container above and in register with the discharge opening and pressing upon the top of the wheel. This plate constitutes a'closure for the receiving end ofk the particular pocket 11 that is placed in`\register with the discharge opening, and is of limited extent to permit communication between the remaining pockets and the interior of the container in order that they may be filled. The plate 12 also agitates the material within the container, a function which is supplemented by the agitator bar 13 mounted to turn with-the wheel.v This bar is desirably continued upon both sides of the shaft 5. 'j f The plate 12 is formed with a depending wing portion 12 attached thereto by means of a screw 122. This portion extends toward the teeth or blades 10 which are vertically spaced apart from the plate 12 itself, and serves to reduce the height of the measured quantity of material to the height of the blades. When the portion 12is removed, it

permits larger quantities of material to remain between the blades for discharge through the discharge opening 2. The plate 12 is positioned, at its inner end, by the shaft 5 whose upper end passes through a hole in an extension of the plate. There is also a lug 123 formed upon the plate, at its outer edge, which is received .in a notch 12'* in the shoulder 125 in the base portion of thecontainer. The cylindrical portion of container 1 that is above thewheel rests upon the shoulder 125 and holds the lug 123 in the notch.

In the preferred embodiment of the invention, the shaft 5 is turned .in a uniform direction and is connected with the wheel to turn it in a like direction. The shaft has a head 14.1ixed thereon and received in a recess in the bottom of the wheel. The

upper end of the shaft is polygonal and en- -measuring wheel step by step by means of the actuating spring pressed pawl 16 car- .20, the measurin against the force of a spring 2() which is sov connected with the hmember 5, 17. 18 as to resist manual movement thereof in a direction that operates the ratchet 15.l A lug 21 upon the bottom of the container defines the resting position of said member. A thumb rest 22l is provided'upon .the container to facilitate the operation of the aforesaid member. Whenever this member is suiiiclently turned against the force of the spring wheel is moved one intertooth space-to brmg another measured quantity of material into register with the discharge opening. The arm 5, atthe same time, moves the closure,v plate from beneath the discharge opening so that material may be discharged from the pocket newly positioned in register with the discharge opening. When the handle bar 19 is released, the spring 20 willretract the member 5, 17, 18 to bring the plate 4 into closed position but without causing a reverse movement of the wheel, the pawl 16 escaping this wheel during the closing' movement of the plate 4. The wheel is held from any backlash movement by means of a roller 23 which is spring pressed into an .inter-tooth space of the wheel preferably by means of the spring 20, in which case this 4spring functions through an arm 24 pivoted at one end and carrying the roller at the other end.

-Three sides of the discharge opening are margined by a wall which is downwardly tapered upon its outer side by which malted milk or other dry material is prevented from caking upon the bottom of the container and around said opening. When such a wall formation is employed, I desirably provide a levelling post 25 along side of the opening that is engaged by the plate 4 when in open position so that the plate cannot tilt out of its normal horizontal plane.

The projection 26, shown in Fig. 2, may

lol

consist of any means adapted to the support I upon the interior wall ofthe container and projecting into the path of the resilient blades 10.

The operation of my dispenser is as follows:

The thumb, having been placed upon the thumb piece 22, and the fingers engaging the handle 19, the lever18 may be actua-ted to the left in Fig. 1, the pawl 16 (Fig.- 5) engages one of the shoulders on the wheel 15 and rotates the wheel 15. The lever 24, with its friction roller 23, is resiliently held be-` tween pairs of shoulders on the wheel 15, and on actuation of the lever 18, the spring ten sion of the spring 20, extending between the lever 18 and the lever 24, is increased, but

the motion of the wheel 15 cams the roller llfl 23 from position between the shoulders to a position upon one of the projections of thel wheel 15, after which the spring 20 forces the roller 23 into thenext notch, on the wheel 15, causingsd wheel with the associated dischargehiechanism to move with a snap ,to its final position.

D uiun the motion of the hub 9 with the resilient lades 10, the blades 10 en age the projection 26 situated adjacent t e disL charge opening, and after being rearwardly sprung by the said -nojectin,`the bladesass over it, each bla e being placed in v1- ration before it reaches the discharge opening. In order to facilitate free vibration o f the blades 10, it will be noted that they are disposed in close proximity to the ,bottom of the container but out of contact therewith, `as wellI as being out of contact with the covering plate 12- Changes may be made without departing from theinvention.
