This invention relates generally to de? vices for dispensing measured quantities of material such as coffee.
It is an object of this invention to generally improve and simplify the construc-, tion of dispensing devices whereby they may be cheaply manufactured in large quantities.
devise a dispensing device which will :incorporate a novel measuring means which may be constructed entirely of sheet metal. It is another object of this invention to devise a dispensing device provided with novel form of support bracket whereby it may be readily detached for refilllng.
Further objects of this invention will appear from the tollowing description in which we have set forth the preferred embodiment of our invention. It is tO be understood that the invention as defined by the appended claims is to be accorded a range of mechanical. equivalents consistent with the prior art Referring to the drawings: I Figure 1 is a cross sectional elevational view of a dispensing. device incorporating the features of this invention. Fig. 2 is a cross-sectional view taken along the line 2-2 of Fig. 1. I j V Fig. 3 is a cross sectionalview taken along the line 33 of Fig. 1.
4 is a detail view showing theflmeans for attaching the closure to the receptacle.
, 5 is a iragmentary detail showing the I method of mounting the agitator.
The invention comprises generally an inverted receptacle or jar having a cup-shaped closure detachably secured to the lower open end of the same the closure carrying means whereby measured quantities of material may be discharged. Thus referring to. the drawings there is shown a receptacle 1O preferably in the formot an inverted glass ar, to the lower open end of which is secured the closure member 11. This closure is preterably in the form of a cup constructed of pressed sheet metal and is provided with an upper rim 12 which is adapted to be detach ably secured to the rim 13 of the ar 10. The particular form of detachable connection shown comprises a plurality of projections 14 upon the outer periphery of the rim 13, these projections being preferably molded integral with the jar and being adapted to engage L-shaped slots in the rim 12. The re- It is a further object of this invention to silient metal tonguesv 16 formed bythe slots 15 are also notched as at 17 wherebywhen the rim is positioned uponthe jar and rota-t ed; the extensions 16 clip overthe projections 14. Preferably the projections 14 are spaced unevenly about the periphery of the rim 13' so that the closure can be only attached in one position with respect to the-jar.
Mounted within the closure 11 and in spaced parallel relationship with the bottom wall 19thereof, there is a metal disc 20 the. periphery of which is seated upon a shoulder 21 extending about the sidesof the closure. Additional means for retaining this disc in position upon the shoulder 21 has been shown in the form of tabs 22 formed integral. with the rim 12 and bent inwardly over the upper surface of the disc.
The disc 20, together with the bottom wall 19, form spaced; inner and outer wallsinclosing a chamber'23 within which is .dis-. v
posed the measuring means. This measuring means comprises a rotatable netal disc 24 of slightly smaller diameter than the stationary disc 20. For centering andfretaining the disc 24 in close contact with the lower surface of the disc 20 its edges are slidably seated upon a peripheral shoulder 26 provided as an integral part of the closure member 11 adjacent the peripheral shoulder 21. The edgesof the. disc 24 are also provided with a plurality of integral depending flanges 27 for engaging the innor surface of the closure'll. I
The rotary disc .24 is providedwith an aperture 29 ofiset from the center of the same. Secured to the underside of disc ,24
adjacent the edges of this aperture is a metal band 30 having an outwardly fiangedupper edge 31 which is secured to the dis'c 24 as by spot welding, and a. lower inwardly flanged edge 32. This band forms a pocket 33 rotatable with the disc .24for removing terial from the interior of the receptacle.
The bottom wall 19 is likewise provided with an aperture 37 With which the lower end of the pocket- 33 is adapted to register when the disc 24 is rotated through an angle of say 180 degrees by means of the lever 34.
Thus in one position of the disc 24 the pocket 33 will receive a measured quantity of material from the receptacle and when the disc is rotatedto bring the pocket into regisflan ed ed e 32 whereby the material bein D D D dispensed will not tend to escape into the chamber 23, or will not am between the stationary disc and the rotatable disc 24.
WVhen the material being dispensed tends to pack within the receptacle it is necessary to employ some sort of agitator movable upon movement of the lever 34. In this instance there is provided an agitator in the form of a 'wire 39 having its upper end extending into the interior of the receptacle and having its lower end extending through central apertures and 41 provided in discs 20 and 24 respectively. This lower end is then provided with an angular bend as at 42 and is extended through an aperture provided in the metal band 30, the inner terminal of the wire being bent over as at- 43. With such an arrangement the agitator is securely mounted tothe rotatable disc without the necessity of employing a. soldered or welded connection;
In order to detachably mount the receptacle 10 to suitable support there is provided a resilient metal band 46 which is adapted to encompass the periphery of the jar, the intermediate portion of this band being flattened as at 47 whereby it may be attached by screws to a suitable support. The free ends 48 of this band are preferably bent'to form grooves 49 which serve to re-' ceive integral ribs or projections 50 provided upon-the surface of the receptacle, thus preventing rotation of the receptacle with respect to the hand. To prevent'longitudinal displacement of the receptacle with respect to the band thereis provided a pair of spaced circumferential ribs 51 between which the band 46 is adapted to be disposed. Other ribs 52 may be provided upon the rear side of the jar to engage the bent portions v53 of the band, thus supplementing the effect of ribs 51. In order to detach the receptacle from the band it is only necessary to spring apart the band 46 and then slide the jar up or down.
It will be evident that a device of this kind may be cheaply manufactured since all of the parts, with the exceptionof the receptacle and agitator, are constructed of sheet metal. Refilling is readily accomplished by removing the jar from the bracket and detaching the closure 11.
To claim: I
1. In a dispensing device, a receptacle having an open lower end, a closure adapted to be detachably secured to said lower end, said closure having a chamber defined by spaced inner and outer walls, a rotatable disc of sheetmetalmounted within said chamber, said disc being apertured, and a metal band secured to said disc adjacent the edges of said aperture thereby forming a pocket rotatable with said disc, said inner wall being apertured to permit flow of material from the receptacle into the pocket, and the outer wall being apertured to permit discharge of material from the pocket secured to said lower end, said closure having a chamber defined by spaced inner and outer walls, a rotatable disc mountedwithin said chamber, said disc being apertured, a metal band secured to said disc adjacent the edges of the aperture thereby forming a pocket rotatable with the disc, said inner
