To all whom t may concern.' v Be it known that I, LUKE J. 'FAIRBANKS, a citizen ofthe United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Dispensers, of which the following -is a specification.

This invention relates to improvements in dispensers, and more particularly to that class of dispensers which are capable of expeditiously ldispensing a semi-liquid mass', such as peanut butter, jams, apple butter and kindred mobile or plastic substances, at the will of the operator. I

An important' object of this invention is to provide a simply constructed, readily accessible, comparatively small, inexpensive, compact, durable and highly efficient dispenser, which'is attractiveA and ornamental in appearance and efficient inoperati'on.

An object of the invention istoprovide for preventing a hardening or: settling of the heavy parts of .-any semi-liquid mass within the container. chamber of the dispenser, to which end I provide means for re-mixing the mass, thuskeeping the mass at all times in its original consistency. The invention. further consists in the particular combination, inter-relation, construction, association and ,relative arrangement of the several parts, elements and features of the dispenser, as illustrated in the drawing, described -in this specification and finally pointed out in the claims.

Other objects and advantages will appear during the course of the following description:

In the drawing:

Figure 7 isa perspective view partly sectioned of one'of theblade elements shown in Figure 3; and,

Figure 8 is a detail 'plan' view partly sectioned .of a handle meanSQandtaken on the line :csm8, Figure 2.

Corresponding parts inall the"figuresare designated by the same reference characters. Referrin particularly to the drawing, the dispenserincludes as one embodiment of the invention acontainer B having a dispensing outlet C, a combined plunger and` scraper D, an agitator or mixer E, both of which are arranged within the container;

handle means F and means G forv rigidly holding the device to'so'me fixed object.

More `particularly the A container B includes-a cover 1 which is provided`with downwardly directed edges 2' for gripping the rim of the container. A portion of the ledge 2 of the-cover is angularly slotted as at 3 to engage -an outwardly projecting lug 4 mounted on the container. Thus a slight turn of the cover 1 acts either to engage the slot 3 with the lug 4, or to disengage same, whereby the container may be locked to the cover orueasily removed therefrom, as desired. g Y

Concentrically disposed within the base'of the containerais an aperture 5 around the edges of which is a downwardly projecting flange or collar 6.

The dispensing outlet C shown in Figures 1 and 2 includes a mouth-piece of cylindrical tubing 7, having one end thickened as at 8 to form a flange 9. l r In order to secure the mouth-piece to the container 'B,the opposite end 10 of the cylindrical tubing 7 comprising same, is exteriorly threaded for a portion of its length, as at 11, to engage an interiorly threaded surface 12 of the fiange 6. 4 i. n.

A cut-off valve a comprising a disc 13 is pivotally fastened tot and held imposition over the thickenedend ofthe tubing 7 by 'means of a screw 14; T o prevent the disc when covering the opening of the mouthures 1 and 2.

The disc 13 has a depending extension or arm 18, which arm is for the purpose of allowingthe operator a purchase on same suliicient to facilitate easily reciprocating or closing the disc 13 over the end of the mouth-piece 7, when desired. l

A modification of the dispensing outlet C is shown in Figure 4 and is similar in all.

details to the outlet C of Figures 1 and 2, just described, with the vexception that a mouth-piece 19 is in the form of a hollow frustum of a cone or an inverted funnel. It should be particularly observed that while the inside surface of the hollow cone 19 is regular throughout, the outside peripheral surface near, the shorter diameters is thickened to form a parallel side or cylindrical surface 20. This surface is provided with threads 21, which threads engage the threads \12 of the flange- 6.

A further modification of the dispensing outlet C is shownA in Figure 5, in which 'a mouth-piece`22 is in allrespects similar to the mouth-piece 19.0f Figure 4, except that the lip 23 of same -is arcuated. The cut-ofi' valve a includes a disc 24, the surface of which is arcuated to correspond to the lip 23. Pivotally depending as at 25 from the liange 6 and at corresponding opposite sides thereof, -are arms 26, which arms are fastened to the edge portion of the disc 24. To operate the valve a, a handle 27 is. mounted on the outside surface .of the disc. To limit the reciprocating movement of the disc in one direction a check 28 is fastened to the mouthpiece 22 as at 29; this check has an arm 30 vextending over the lip 23 and is capable of engaging the edge of the disc.

Within the container B is the circular 'plunger or scraper D having an opening or aperture 31 at its median portion and around which is disposed 'al collar 32 integrally formed with the pl/unger. A sleeve shaft 33 has aportion of the peripheral" surface of v one end as at 34, flushly surrounded by the an aperture 36in thecover 1.

collar 32 and joined each to the other by means 35 passing through the collar 32and embedded in the shaft 33, which shaft 33 in turn passes upwardly for a distance through mentioned that the aperture 36 is in co-axial alignment with the aperture 5 in the base of the container B.

(3o-axiallyI disposed within the sleeve Ishaft`33 is an extended central shaft 37` which carries amixer or agitator E located within the containerB and below the plunger D.

It might be.

Referring to Fig/ure 7, each blade 38 is given a longitudiiial spiral set and pitched as shown by the transverse. vertical section 41. While the depth of the blade as shown at 42 is constant throughout its length, the surface 43, which in practice is the top surface of the blade, progressively varie-s in width from hub to tip, so that in contour it resembles a one-half crescent.

The handle F, provided with a ydetent 44 is slidably mounted upon the shaft 37. The detent includes two arms 45 and 46 integrally formed and at angles to each other. One of the arms 45 is pivotally mounted onl the handle hub 47 by means of a bracket 48, while the other arm 46 passes through an aperture in the hub 47 and normally engages, when desired, any one of a plurality of internal recesses 49 longitudinally arranged on and located in the shaft 37. ,A spring 50 isso mounted between the arm 45 and the handle F as to exert an outward pressure against the arm 45, thus ensuring that the arm 46 will not slip out of any one of the recesses 49 until such time as the operator exerts a downward preure against the arm greater than the outward erted by the s ring.

The means for'securing the dispenser A to some object, includes a bracket 51 provided near one end of same with fingers 52, which fingers in.v turn connect with the peripheral surface ofthe container B. The opposite end of the bracket is provided with adjustable clamping jaws 'b which include fixed and movable jaws 53 and 54 respectively. The fixed jaw 53 is placed under the object, and the movable jaw 54 which slides co-axially'upon ,the arm'51 4of the bracket G, is pressed downwardly on the opposite surface of the object and the lock bolts 55 i and 56 turned. 4

The operation, uses an(l'a. LlVantages of this dispenser are as follows:

`,To use a concrete example, suppose that the dispenser A is mounted upon a counter in a grocery store, and it, is desired that the container B be used for peanut butter.

At the present time peanut butter is seldom J handled in grocery stores owing to the dificulty of successfully dishing same from -any form of container. In my invention, the cover 1 1s first. removed from the con- 'tainer B, and, the agitator E and plunger D dispensing outlet 5. 0f the container B, the

masses y Naturally the grocer' would be desirous of ascertaining 'the cubic contents of the conv imately,

tainer B, andif possible the exact weight of the peanut butter to be dispensed through the dispenser'outlet C.

A scale 57 showing the cubic contents of the container B is marked longitudinally upon the sleeveshaft 33. There is likewise provided a scale 58 which designates thenumber of pounds that. might approximately be within the container B. I say approxbecause different plastic substances would. vary in weight. In practice, the sleeve shaft 33 is made of wood, and the interior surface is lined.

with metal cribbing toredu'ce any wear that the shaft v37 might incur.

Now, if a customer were to desiresay three pounds of peanut butter, the 'grocer would plat-e a small bucket beneath lthe dispensing outlet C and would press downwardly with one hand upon the sleeve shaft 33 and move .the disc or closure means 13 past the mouth`of the dispensing outlet C. The peanut butter would now flow outwardly and into the bucket due to the pressure exerted by the plunger D.. The grocer would at all times' watch the scale 58 and.

when the' plunger had moved downwardly fa sufficient distance, sayl to where it registered' approximately three pounds on the scale 58, he would immediately close the disc 13 over the dispenser outlet C. Thedisc 13 being thin wouldA act as a. cutting.

element and^ sever the contents discharged from the outlet C.

Figures 4 and-5 show a modified form of e the dispensing outlet C which has been As previously found more satisfactory than the 'dispensiiig outlet illustrated inv Figure 1 and 2. described it is made in the frustum of a `hollow cone because plastic substances adhere less rea ily to a sloping wallthan they do to a straight wall. f Furthermre, it ismuch easier to succefully clean-a dispensing outlet of the ltype shown in Figures 4 and 5 than that shown in Figures l and 2.

Let us suppose that the peanut butter within the container B becomes hardened; the oil-will r'ise to the surface and thehard substance will drop 'to the bottom. Naturally it would be impossible now to remove any of the peanut butter through the dispensing` outlet C, regardless .of any pressure that might be exerted by the operator upon the plunger D. To overcome this condition the agitator E lis so disposed within the container-B that it may be reciprocated orrotated in. accordance with movement ofthe shaft 37. By a.

plunger. both saidplunger and the plunger being combined 'rotation of the shaftv 37. aided bythe handle F and reciprocation, the peanut butter may be thoroughand returned to its original at which time it will be possible to again successfully dispense same. Furthermore, the blades 38 are given a spiral setvand a negativepitch in ordei-that the ly re-mixed consistency,

plastic substances within the container B may be moved to acommon center when the agitator E is rotated.

l'.JIt is obvious that'many changes and variations and modifications may .be made in departure from the particular description and showing of the accompanying drawing i nadapting the invention to varying conditions vand requirements of use and s ervice, without departing from the true spirit of the invention.
