mrxme DEVICE.

Application medium 21,. 1923, Serial oughly commingle such products with the fluid which is in the mixing container. The rapidit with which this can be done is my main 0 ject. Other objects are hereinafter set fort I accomplish these results by means of the device hereinafter described and illustrated on the accompanying drawing, in which F igure 1 shows the agitator andan inside view' of the container. Figure 2 is a separate view of two sides of the container, showing the shape of the vanes therein. Figure 3 is a sectional view ofthe screw along the line 3 in Figure 1. Figure 4 shows a modified I jacent to the bottom, in an upward direction,

form of propeller. The device consists of an agitator constructed with a stem 4 having a screw thread 5 projecting from a portion of. said stem, and terminating at the bottom with an enlarged screw 6. A propeller 16 shown in Figure 4 can be substituted for the screw 6.

I have formed three channels equidistant apart across the thread 5, but a smaller or larger number of such channels can be used. 7 is a nut at the top of the stem to attach the bit, or agitator to a shaft 8 of a motor 18, or other source of power.

The container shown as 9 contains a pluralit of uniformlycurved vanes 10 on the insi e thereof. In the drawing I have shown the container shaped'like an inverted frustum of a rectangular pyramid. The vanes are shown as beginnin at the lower right hand corner of the si e of the contamer and' curving upwardly toward the right, the radius of the'curve decreasing to ward the upper end. One of these vanes should be on each of the four sides of the inside of the container. I do not want to be confined to a container having four sides only inasmuch as it is practical to use a container formed with a larger number, and with vanes formed on each of-the sides. Or the container can be the shape of an inverted frustum of a cone, or tubular, and a plurality of vanes can beplaced inside starting at the bottom andcurving upward to- No. 046,743. Renewed Ianuary 5, 1926.


ward the-left, The object of the vanes is to force the contents of the cup downward and to break or crush lumps and fruit which is in the mixture in the cup. -It is also noted that the relative diameter of the screws 5 and 6 are shown in the drawing and such relations should be adhered toapproximate- 1y: The screw 5 is approximately two-thirds the diameter of screw 6. The screw 6 should be proportionately short, to wit, approxi-. mately one-sixth of the length of screw 5. The threads of screw 5 are broad at the base and taper to a sharp edge along the circumference. The threads of screw 6- run opposite to the threads of screw 5, threads 5 being left handed. In using this device the agitator is attached to the shaft of a motor or source of power which will give it a rapid rotary motion in the direction of the travel of the hands of a watch. When thus rotating, the screw or propeller 16 tends to throw the contents of the cup, which is adand screw 5 tends to throw the contents of the on downward. The sharpedges and broad ase of screw 5 which is aided by the lateral channels 8 hereinbefore referred to, makes the screw 5 act as a cutter and the rapid rotation of the agitator will chop, mangle or break the fruits, ice, ice cream, malt, and similar ingredients into small particles and will assist in dissolving them. The channels 8 hereinbefore referred to serve to permit the fruit and other contents of the bottom of the cup to be raised upwards so the knives formed by the cutting portions of the screw 5 cancutsaid fruit.

In my experiment a mixer of this character will thoroughly mix ingredients in one-fifththe time necessary to perform the same degree of work by other mixers now in use, and the construction of the vanes and screws as described keeps the contents of thecontainer therein while being agitated.

I claim as new and ask for Letters Patent v 1. In a mixer, in combination with acontainer, an agitator adapted to be rotated within the container, the agitator consistin of a stem having a circular plate threade on its periphery attached to the bottom, said stem having an enlarged diameter above the bein approximately one-half to two-thirds the iameter of the slate, said stem being adapted to be rotate 2. In a mixer, in combination with a container an agitator consisting of a stem having an enlarged threaded head at the lower end, and a reverse threaded ortion adjacent to the head, said reverse t readed portion havin transverse channels thereon, said agitator ieing adapted to be rotated.

3. In a mixer, the combinationof a container having interior vanes extending upwardly and curving toward the left at the upper end thereof, and an agitator consisting of a stem terminating at the lower end with a right hand screw having an enlarged diameter, and having immediately above the said lower screw, a left threaded screw of lesser diameter than the lower screw, the left hand screw having channels cut transversely across the threads, and means for rotating the agitator clockwise, substantially as described.

4. In a mixer, the combination of a container having interior vanes, and an agitator adapted to be rotated vertically withinjthe container, the agitator having a screw propeller at the lower end, and a screw of less diameter and with reverse threads to the propeller immediately above said propeller, and channels'being formed transversely and to the depth of the threads, substantially as PETER G. HINES.
