i Murine APPARATUS.

Application filed. August 16, 1921. Serial No. 492,657.

To all whom t may concern:

Be it known that I, HOWARD A. VARFEL, a citizen of theUnited States, residing at Yorktown, in the county of Delaware and `@tate of Indiana, have invented certain new and useful Improvements in Mixing Apparatus, of which the following is a speciiication. i

This invention relates to apparatus for mixing food materials and beverages on the order of melted milk and the like.

Particular objects of the invention are to provide practical and efficient mechanism for mixing either one or a number'of drinks or other concoctions, as may be required, and further, to make the apparatus in convenient attractive form and quiet in operation.

The various novel features by which these objects are attained will become apparent from the following specilication which is to be read in conjunction with the drawings accompanying and forming part of the same and which disclose the invention embodied in but one of its possible commercial forms. Figure l in the drawings referred to is a side view of the mixing apparatus with the base portion of the device shown in section to illustrate the driving gearing and switch operating mechanism.

Figure 2 is a bottomplan view of the apparatus.

Figures 3 and 4 are broken enlarged sectional views showing one of the mixers in the up-raised, inactive and lowered, operative positions respectively. Y

Figure 5 is a detached perspective view of one of the glass holders.

Figure 6 is a broken side elevation of the latch release. y Figure 7 is a broken plan view of the same.

Figure 8 is a horizontal sectional view of this mechanism as taken on substantially the plane of line 8--8 of Figure 6. f

Figure 9 is a broken sectional view of the stationary section of one of the columns and the switch operating mechanism associated therewith.` 1

Figures l() and l1 are horizontal sectional views of the switch operating cam mechanism taken on substantially the plane of line 10-11 of Figure 9.

In the machine illustrated, there are four mixers, any one or all of which are operable at will from a single driving motor.

These mixers are shown in Figure l as mounted in a row on a suitable supporting base l5 which is hollow to form a housing for the gearing and switch mechanism, the motor 16 being supported on this base at one end of the row of mixers.

These mixers, as more clearly shown in Figures 3 and Ll consist in each instance of a tubular column 17 carried by a flanged bushing 18 having a squared hub 19 seated in a correspondingly shaped opening in the top of the base. said lixed column having an oversliding tubular extension 20 carrying the mixing element 21 and a disconnectable part of the gearing for `actuating the same.

The telescopic column section 2OA is shown as non-rotatablyguided on the fixed column section by having a part 22 slidingly fitting over an upstanding guide rod or post 23, which has a head 24 at its upper end to limit the retractive upward movement of the movable column section.

The mixing element is shown as carried by a spindle 25 having a screw-threaded connection at 26 with the vertical shaft section 27 journaled in the head 28 of the movable column section and connected by bevel gearing 29 with one end of a horizontal shaft 30, whose opposite end is connected by bevel gearing 3l with a vertical shaft section 32 journaled in a bearing 33 carried by the sliding column section.

The sliding column section is thrust upward by a spring 34 interposedbetween the shoulder provided by the bearing 33 at the top of the sliding column section and the shoulder provided by the bearing 35 in the upper end of the fixed column section. In this latter bearing there is journaled an upright shaft 36 of tubular construction to receive the lower end of the upper shaft section 32 which may be pointed as indicated at 37 to facilitate its entrance into the end ofthe tubular shaft and which carries clutch disc 38 slidingly keyed thereon at 39 and adapted to be coupled with a corresponding clutch element 40 on the upper end of the tubular shaft. The clutched engagement of these two shaft sections is illustrated in Figure 4, wherein it will be seen that the upper shaft section 32 telescopes into the lower tubular shaft section 36 and that the sliding clutch disc 38 engages with the clutch member 40 to afford a driving connectionV between these parts. The clutch disc 39may be actedL on byf a spring which will yielding-ly, holdy it engaged with the driving element 40, the end of the key way at 39 in the shaft forming a stop to limit the extent of sliding movement of the disc.

The drive shaft-s 36 in the illustration are provided with pulleys 41 at their lower ends, within the hollow base, over which runs a driving belt 42, said bolt also passing over tioilsintofposition tov be engaged and forced tact-springs. 58.

back by the. oversliding column sections, said cam members being affixed to the upper ends of upright. controlrods 51 within the columns and which carry at their lower ends arms52- inengagement with lugs 53 on the longitudinally shiftable switch actuating rod 54.

This latter rod is` shown in Figure 2 as normally forced to the left by a spring 55 andv as having an arm or extension 56 carrying-a contact-57 adapted to bridge the con- The switch thus provided isinterposed in the motor circuit and consequentlythe motor is` under the direct control of each and all of the mixingdevices.

Some means are preferably provided for retainingthe .mixing devices in their 'lowered'operative positions lf have shown for this purpose, a hook ordog 59 pivotally supported at 60 in eachy of the lined column sections and arranged` to project through an opening 61 into holding engagement in the opening` 62in the slidingcoluinn section, as shown. .in Figure 4. These holding dogs are shown Las thrust outwardly by sprin 63 so that-they will :automatically snap into holding engagement with the sliding column sections when the same are lowered to bring the mixers into operation.

Toreleasethe hold-down latches, I have showneach mixer head as provided with a handle164 having a stem 65 journaled in a bearing-66 at the sideof the head and carrying at yits lower end, an angularly extending arm 67 arranged in` the depressed position of the head to .overlie the point of the latchingdog. K

The glasses or other containers are located and held in position beneath the mixers by positioning devices .shown in the form of sprmg-,yokes 68 having4 curved arms to rece1-ve, and.;part1ally embrace the glasses, said yokesbeing set in slotsgtfxcuty in the upper ends of the posts 70 which having squared lower ends 7l seated in correspondingly shaped sockets in the@ top of the base and split as indicated at 72 to form springv tongues frictionally engaging in such seats. This construction causes the glass holders to be firmly held in place and yet enables their ready removal for cleaning or other purposes. This detachability is particularly important where it may be desired to operate on material which may be `withina bowl. or relatively large container.

In the ordinary yuse; of the invention, the glass or glasses containing the ingredients are slipped into place in the glass holders and the mixer heads are depressed to lower the mixing elements down intol the material in- 'the glasses. As the first mixer is depressed and the upper column sectionthereof rides over-the cam 49the switchwill be thrown and the motor started' in operation.

In the continued loweringrmovement and,

after the mixingA elementhas been lowered fully into the glass, the upper shaft section will enter the lower tubular shaft section and the two will become clutched together, resulting in the driving of the mixing element. It will be evidentl that the mixing` Hence the mixing element is in. an idle on non-rotating condition when it is lifted ont,`

of the glass. f y.

This prevents scattering the material as the miners are withdrawn. Tf onlyonemixing device is in operation, the vswitch restoring spring 55 will operateto cut out the motor as soon as the movable section of the celumn slides free of the, switch operating cam 49, but the motor will not be cut out of circuit untiil all the mixers have been withdrawn. i
