19 Claims. (lol. 22e- 153) invention relates to the art of dispensing devices and more particularly to a device for hispensingmeas'ured quantities of powdered soap, flour, sugar, coffee and other powdered or 'granular substances.

It is 'among the objects of this invention to provide a rugged and compact dispensing device of neat and pleasing appearance that will keep the contents clean and free from dust and dirt, that will not clog, that is simple to ll, yet once filled is substantially tamper-proof, that ,has few moving parts, is inexpensive and 'easy to vcon- 'structand Lservice and will dispense measured quantities of 'powderel or granular material without waste. W

A feature of the v'intention is the lmounting of the container-fin inverted position upon the shelf `of a supporting bracket carried by a wall plate, which bracket, fog-,purposes of charging or re'- charging `is rotatable about a horizontal 'axis perpendicular to the wall, so that the container is upright as the shelf reaches inverted position. The parts are so constructed that after charging,

tfhe turning of the bracket about its axis to ermal. position results preferably in three auto,- -f'matic operations-i. e., the Vlatch'ing of the bracket with respect to lthe wall plate, the locking of the container in its inverted position upon the bracket shelf, and thecovering by the bracket and therefore the concealment ofthe screws that mount the wall plate. The latch that holds the bracket in 'xed relation on the Wall plate is re' .leasa-ble only by the initiated, so that the device is tamper-proof and access lto the contents of the container is not possible except for discharge through a dispensingappurtenance that is inco'r'por'ated 'in the shelf structure of the bracket. I n a preferred construction, the pivot mount is formed by a hub in the bracket plate, which 'hub is lodged in alcorresponding opening in the ugual] plate, "the parts being assembled by a retaining ring secured to the rear face f the hub which overlaps at its rim an annular ledge about said opening. The retaining ring preferably controis the bracket-retaining latch, andto this end preferably has "a notch on its periphery, which, when the bracket is in normal operating position,

.r coactsA .with a spring-urged latch mounted in the wall plate. a ving ltherethrough adjacent its periphery for a Theretaining ring also has an openstructed as to allow the lock pin to be urged to unlocking position when the bracket is rotated to inverted position.

Referring now to the drawings, the dispenser includes a container II substantially cylindrical in shape, preferably having a slight outward taper fromithe rounded dome I2( thereof to the open rim I3 and a circular sight aperture I4 in the wall thereof. That aperture` has an annular depressed ledge I5 about its periphery, in which is seated a transparent window pane I6 of glass or plastic, thereby enabling the `contents of the container to be readily viewable.A` The window pane is retained on its seat I5 byfa name plate I'I which has a circular aperture I4' therein having a diameter slightly less than the diameter of the pane. The name plate is affixed to the container by lugs I9 which pass through slots I9 in the wall of the container.

Extending longitudinally of the container II from the rim thereof are a plurality of bayonet hooks 2I unequally spaced 4for the purpose set forth, each having a laterally extending finger 2|'. The hooks 2| extend laterally from a strap 2|' spot-welded to the container near the lower edge thereof. The container II is removably mounted on a base or shelf 22 which has a plurality of slots 23 therethrough correspondingly spaced about its circular platform 21 so as to receive bayonet hooks 2 I.

Base 22 is formed as the shelf part of an integral bracket 24 that includes a bracket plate 25 at right angles thereto and rising from said shelf at the rear thereof and by means of which the bracket 24 is aixed to a substantially rectangular wall plate 26, as will hereinafter be described.

The circular platform 21 has a bearing opening 28 therethrough at the axis thereof and a dispensing opening or inlet 29 therethrough near the periphery thereof. A hub 39 coaxial with opening 28 and unitary with the shelf 22 extends downward therefrom and has a conical bearing therein accommodating the substantially corneal rotatable hollow shaft 3| which has a threaded opening 3| at the upper end thereof and which mounts the valve assembly 32 and the agitator frame 33 and protrudes from the surface of platform 21.

The valve assembly comprises a substantially arcuate segment 34 unitary with shaft 3| and extending laterally therefrom at the lower end thereof. Segment 34 has a. radially and outwardly extending handle arm 35 unitary therewith at one edge thereof protruding beyond the downturned flange 36 of shelf 22. Idly mounted on the protruding end of shaft 3| is a washer 36 having a thickness slightly less than the distance from the surface of platform 21 to a square head 31 at the upper end of shaft 3|. The square head 31 is adapted to receive the corresponding square opening 39 near the inner end of a laterally extending arm 38. The free end of arm 38 has downwardly turned lugs 49 thereon which extend into slot 4| in a valve member 42 for operating the latter. The valve member 42 is angularly displaced from segment 34. The valve member 42 is dished to present a downturned rim 43 which rides on the upper surface of platform 21, as shown in Fig. 2.

Agitator frame 33 which comprises essentially a plurality of substantially sinusoidal arms 44 extending radially from the spokes of a hub 45 of the frame joined at their extremities by a rim 46 is afixed to shaft 3| at the threaded upper end thereof by means of a screw 41 which passes through an opening 48 in said hub. Desirably, the agitator is made from a unitary stamping of sheet metal comprising the hub 45, the rim 46 and sinusoidal radial arms or spokes 44, each of which arms or spokes is bent out of the plane of the stamping to extend at right angles thereto,

as shown. A lock washer 49 surrounding screw 41 serves securely to lock the latter. Thus, the single shaft 3| serves as the axle for the valve assembly 32 with its segment 34 below shelf 22 and its valve member 42 and agitator frame 33 above said shelf.

A hub 50 which has a downwardly and outwardly flaring frusto-conical cavity 5|, protrudes downwardly from dispensing outlet 29, is unitary with the shelf 22 and serves as a measuring chamber for the contents of the container. Extending outward from hub 50 and unitary with shelf 22 are arcuate guide rails 52 upon which segment 34 rides, each of the rails having a downwardly extending stop 53 at the end thereof to limit the lateral movement of segment 34.

The bracket plate 25 has a circular hub 54 on the rear thereof which is lodged in a circular opening 55 in wall plate 26 and plvotally retained therein so as to be rotatable in either a clockwise or counter-clockwise direction by a retaining ring 56 secured to the rear face of hub 54 by screws 51, the heads of which are countersunk in holes 58 in the retaining ring and the shanks of which are threaded into holes 59 in the hub. The rim of the retaining ring 56 overlaps an annular ledge 60 on the periphery of opening 55 in the wall plate and is slightly spaced therefrom, due to the fact that hub 54 is slightly thicker than ledge 60, thereby affording a horizontal pivotal mount of the bracket to the wall plate, whose pivot axis is at right angles to the wall and which is of a large diameter, of the order of the width of the wall plate,

Bracket plate 25 has a bore 6| therethrough which extends through a boss 62 unitary with and at the undersurface of shelf 22. Boss 62 has a bearing end 63 in juxtaposition to one of the slots 23 in shelf 22. A lock pin 64 having reduced portions 65 and 66 at the ends thereof forming shoulders 61 and 68, respectively, is slidably mounted in the bore and extends therefrom at both ends thereof. A coil spring 69 which surrounds reduced portion 66 reacts at one end against bearing end 63 and at the other against shoulder 6l, and thereby urges said shoulder against retaining ring 56, with end 65 of the pin protruding through aperture 10 in said ring, as shown in Fig. 6.

The lower end of wall plate 26 has a groove 1| on the inner side thereof extending longitudinally of the plate radially outward from annular ledge 60. A latch bar 13 is slidably mounted in said groove and biased toward retaining ring 56 by coil spring 14 seated in the groove. The retaining ring 56 has a notch 18 on the periphery thereof which is so positioned that latch bar 13 may enter therein only when the bracket 24 is in normal operating position. Latch bar 13 has a hole 15 therethrough aligned with slot 12 in the wall plate 26, into which a bent wire key 16 may be inserted through a notch 11 in the flange 36 for the purpose hereinafter described.

A cam plate 19 is affixed to the rear of the wall plate 26 at the lower end thereof by means of screws 83 which pass through holes 84 in the mounting portion of said cam plate and thus confines latch 13 and spring 14 within groove 1|. The cam plate serves to operate lock pin 64 and is preferably of relatively thin sheet metal comprising two curved arms 8| extending outward from mounting portion 89 forming a gap 82 between the free ends thereof. Each of the arms 8| is adjacent and substantially parallel to retaining ring 56 and has an outwardly turned camming surface 85 at the end thereof.

Wall plate 26 which has a rearwardly turned skirt 86 on the perimeter thereof has, on its inner side at the upper end thereof a substantially arcuf ate ledge 81 to which is affixed by screws 88 a corresponding segment or lock strip 89 by which it is hung on a mounting plate 92.

The mounting plate, preferably of sheet metal, is affixed to a wall or post by screws 98 extending through apertures 91. The mounting plate has a forwardly turned flange segment 9| on the upper edge thereof over which the lock strip 89 is passed in hanging the wall plate 26 therefrom. The mounting plate also has forwardly turned lugs 96 at the lower edge thereof, projecting outward from the plate to the same extent as segment 9|.

The wall plate 26 is mounted by hanging the same over the forwardly turned flange segment 3| which is thereby straddled between the lock 1l strip 89 and the wall plate proper, with the lower 5.. part of the wall plate in engagement with the free ends of lugs 96. The wall plate 26 is affixed to mounting plate 92 by means of screws 93 through holes 94 into threaded openings 95 in said mounting. plate.

The assembled device has the mounting plate alxed to the rear of the wall plate in the manner heretofore described so that the mounting plate straddles the cam plate and the rearwardly turned skirt 86 on the perimeter of the wall plate encompasses the mounting plate, thereby concealing the operating mechanism.

Installation and operation To install the device, mounting plate 92 is afilxed against a wall or post by means of screws 98, with flange segment 9| at the upper end thereof and lugs 96 at the lower end thereof extending outwardly from the wall.

With the bracket upside down, as shown in Fig. 1l, the wall plate 26 is placed firmly against the wall over mounting plate 92 so that lugs 96 on the lower end of the mounting plate abut against skirt 86 on the perimeter of the wall plate. The latter is then slid downward so that lock strip 89 on the underside of the wall plate slides behind flange segment 9| at the upper end of the mounting plate. Screws 93 are then inserted through holes 94 in the wall plate and threaded into openings 95 in the mounting plate, thereby holding the dispensing device rigidly to the wall.

Container filled with the powdered soap or other material to be dispensed, is placed against the inverted base or shelf 22 so that the bayonet hooks 2| enter slots 23 therein. By reason of the unequal spacing of bayonet hooks 2| and their slots 23, the container can be mounted only with its window I6 facing outwardly. The' container is then turned about its axis in a counterclockwise direction, as shown in Fig, 11, so that the laterally extending fingers 2| of the bayonet hooks 2| extend under one edge of each of the slots 23 respectively and holds the container to the shelf.

Bracket 24 with the retaining ring 56 and carrying the container thereon, is then turned on its pivot mount toward its normal position. As shown in Fig. 6, as the end 65 of lock pin 64 contacts a camming surface 85 of arm 8|. pin 64 will be forced inwardly, projecting end 66 thereof beyond bearing end 63 against the rear edge of bayonet hook 2 as shown in Fig. 7, thereby locking the same against movement fr-fm locked position and preventing removal of container .As bracket 24 in its movement about its pivot mount reaches normal position, as shown in Fig. 8, latch bar 'I3 will snap into notch 18 in retaining ring 56, and thus will latch the bracket in fixed position for normal use of the dispensing device.

The bracket plate 25 in .its position of use, covers and conceals mounting screws 93 and therefore renders the latter inaccessible, as shown in Fig. 1, but through notch '|l it renders accessible the lslot 12, for unlatching said plate 25.

To remove material from the dispensing device, arm 'is moved laterally as far as it can go, first in one direction and then in the other. as limited by stops 53. Each time arm 35 is moved, agitator frame 33 aflixed to shaft 3| will vagitate the material in the container, thereby Apreventing 'clogging of the same. Movement of arm 35 will alternately close the bottom end or outlet of the measuring chamber and open the mouth or inlet 29 thereof, thereby allowing the 75 chamber to ll and then close the mouth 29 while opening the bottom end thereof, thereby allowing a measured quantity of material to be dispensed therefrom. The cavity beneath the dished closure member 42 allows whatever powder that may creep under the closure member as it is moved back and forth to be pushed into the measuring chamber without packing or jamming which might result if the closure member were flat.

For service of the dispensing device, as for recharging the same, a bent wire key '|6 is inserted through slot '|2 into opening 'l5 in the 1atch bar 13 and then pulled down, drawing latch bar 13 out of notch 18 in retaining ring 56. The bracket is rotated slightly in either a clockwise or counter-clockwise direction from its normal position, which will place the latch bar 13 against the periphery of retaining ring 56, as shown in Fig. 9. Wire key 16 is then removed and bracket 24 is then rotated approximately degrees to the inverted position, shown in Fig. 11.

When bracket 24 is in said inverted position, lock pin 64 is clear of cam 8| and therefore is pressed outward by its spring 6| from the container locking position shown in Figs. 5 and 7 to the unlocked position clear of the bayonet hook 2|, as shown in Fig. 6.

The dispensing device herein described is thus compact and neat in appearance, being mounted on a wall in such a manner that all the mounting screws are concealed with the entire operating mechanism enclosed by the container and the wall plate, thereby keeping the parts free from dust or injury. Inasmuch as the closed container is locked to the base when the device is in use, the user cannot reach into the dispenser and wastefully remove its contents and cannot dele or moisten the otherwise dry powdered contents to the extent of caking it to the point of clogging the mechanism. As the container must be inverted in order to be removed from the base, it is simple for it to be relled and replaced without spilling any of the contents thereof. The wide open bottom of the container when removed from the base affords easy access to the inside, thereby rendering the same simple to clean.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope of the claims, it is intended that all matter contained in the above description or shown in the accompanying drawings, shall be interpreted as illustrative and not in a limiting sense.
