This lower bar is preferably located a substantial distance above the lower end of said of the mass". A further object of the invention is to provide a simple device of the character described wherein the means for ribbonizing the commodities is spout. A ribbonizer 2B is loosely journaled on the shaft 23 between the bars so as to freely rotate and in motivated by a ?owing mass, thus requiring no 20 cludes an elongate axial sleeve 29, surrounding the shaft and a, helical vane 39.

The vane is made just long enough In the drawing, the numeral l0 designates a to intermingle the commodities only sufficiently generally rectangular hopper having an out wardly directed marginal flange H at its top.

It is preferable to terminate the vane below complementary cap plate [2 rests upon the ?ange and formed integral therewith, is provided with 40 the bottom of the hopper so as to give the com an upstanding transverse boss l3. modities an opportunity to enter’ the spout be The boss is provided on its front and rear sides with reduced ears l4 registering with ears l5 projecting from the ?ange ll.

The sleeve extends below the vane through the ears I4 and I5, removably fasten the 45 so as to rotate on the lower bar 21 and provide hopper to the plate. The boss is provided with ample clearance between said vane and the bar spaced internally screw-threaded openings or to prevent choking. inlets Ii’, into which feed pipes 18 and i9, re In describing the operation it will be assumed, spectively, are screwed. These pipes may lead for the purpose‘ of illustration, that chocolate ice from ice cream making machines or other sources 50 cream from a packaging (batch) or a continu ous freezing machine is fed through the pipe MS to feed creams of different flavors and different colors into the hopper Ill. and that vanilla ice cream is supplied from an other similar machine through the pipe [9 into the hopper l0. Since the pipes are cylindrical The spout may» have a 55 and are spaced so as to deliver their streams The hopper is in the form of a transition in that it is merged at its lower end into a vertical cylindrical spout 20. 2,409,339 3 at opposite sides of the rectangular upper end of the hopper l0, and since such sides are in clined'and substantially ?at, the streams will slide down the same to the spout 20. Owing to the fact that substantially no agitation occurs in the hopper, little or no intermixing of the commodities occurs in the passage down through the hopper. Upon entering the upper end of the spout the ‘ 4 wardly. This will permit the sleeve 29 to be tilted to one side of the upper bar 22 and by pulling said sleeve upwardly and turning it in a clock wise direction, the vane will be screwed out of the hopper. The separated parts may then be thoroughly cleansed. The foregoing description of the invention is explanatory thereof and various changes in the size, shape and materials, as well as in the details commodities will come into intimate contact and 10 of the illustrated construction may be made, with will unite in a single stream, but will not inter in the scope of the appended claims, without de mix. This stream will flow down onto the upper parting from the spirit of the invention. portion of the vane 30 of the ribbonizer 28 and What I claim and desire to secure by Letters substantially ?ll the cross-sectional area of the Patent is: spout. The ribbonizer offering negative resist 15 1. A device for producing a single variegated ance will thus be rotated by the downwardly frozen commodity from at least two moving dif ?owing stream and the two commodities, thus ferent frozen commodities from separate sources intermingled or ?guratively, twisted, so as to pro of supply including, a single conduit having a duce 'a variegated or ribbonized mass as the stream plurality of spaced inlets at one end thereof and passes along said vane. The stream after leav 20 for conducting the said differentiated frozen com ing the vane will ?ow down the spout and dis modities in a moving differentiated frozen mass, charge therefrom. ' said conduit having an outlet at its opposite end, Due to the thick consistency of ice cream and and rotatable means having an axis coincident the like, the chocolate and vanilla creams will with the longitudinal axis of the conduit be to a large extent remain segregated, but the mass 25 tween said inlets and outlet actuated solely by will exhibit a variegated or ribbonized effect which the movement of the frozen mass for inter will be preserved in the dispensing of said mass. twining said di?erentiated commodities without As the ribbonizer 28 offers little or no resistance intermixing the same, said rotatable means ex to the ?ow of the stream, but freely rotates, such tending to either side of said coincident axes. ?ow will not be appreciably impeded. 2. A device in accordance with claim 1, where The device is readily cleaned. By removing in the rotatable means is formed with a single the bolts IS, the hopper l0 and spout 20 may be easily detached. The shaft 23 may be removed simply by grasping the head 25 and pulling up complete spiral blade. J. D. BALLARD.
