PETERS MIXING' APPARATUS Filed March 28, 1929 INVENTOR ATTORNEY .i July l, 1930 PATENT oFFi'cE UNITED STATES .um Pn'rnns, or nosLYN HEIGHTS, NEW Yonx, assrGNon 'ro THE Tonno-mixen conPoRArIoN, or NEW Yonx, N. Y., A conroarron or NEW Yonx mxme mamme application mea Ieren as, 192e. serial no. 350,491.

My invention relates to mixing apparatus, and especially to an arrangement or mechanism by which the mixer proper may easily be moved to and from operatlve position in a tank containing the materials to be mixed.

The apparatus is adapted for mixing a great variety of materials. A sufficient example of its utility is in the manufacture of paints, where the pigments, oil or other materials are measured into tanks and it is desired to position a tank at the mixer and readily lower the mixer into position, and remove it after mixing is completed.

The characteristics and advantages of the invention are further sufliciently explained in connection with the following detail description of the accompanying drawing, which shows one representative embodiment. After considering this example, skilled persons will understand that many variations may be made without departing from the principles disclosed, and I contemplate the employment of any structures that are properly within the scope of the appended claims.

In the drawings:

Fig. 1 is a side elevation of an apparatus embodying the invention in one form.

Fig. 2 is a top plan.l

The mechanism is supported on or about a frame or standard 1 which may, as shown, be of generally channel section in horizontal planes, although the trame structure may vary greatly. In one preferred form, as shown, the frame is a casing including la base 2, side walls 3 and a front wall 4.

The mixer proper may be of any suitable type.. As shown, the mixer is of what is known as the turbo7 type, including a rotor '5 surrounded by a generally annular deflector 6. Y The deflector is carried by upright struts 7 from an annular frame 8. 0n this frame are uprights 9 supporting the casing of an electric motor 10. A shaft 1l which may be the motor shaft, or connected thereto, carries the rotor The entire mixer structure, in-

cuding the 'proper *rame 8 and motor 1 1- if.

LU. stript/11%). teni .x4-i" purs L t arm.. .LL al iv are p11/orally mounted at 14. on side walls m the standard, and at their other ends are pivotally connected at 15 to the motor casing or a frame member supporting the casing. The lower arms 13 are also pivotally mounted at 16 on the side walls of the standard, and at their other ends are pivotally connected at 17 t frame 8. The pivot locations are such as t provide for parallel motion; that is, the mixer structure, and especially shaft 11, are maintamed 1n vertical position as they are moved up and down.

To facilitate movement of the mixer, counterbalancing means is provided, consisting of a counterweight 20 carried by a chain 21,

' running overa pulley or sprocket 22 and having its other end connected to a crossbar 23, this crossbar being connected to the two arms of either pair of arms-specifically, as shown, to the lower arms 13. The s rocket 22 is car ried on a shaft 24 mounte in bearin at the upper ends .of the side walls o the standard.

The counterweight may be adjustable, as by providing a plurality of separate weights 20", on the general plan of scale weights, so that an accurate counterbalance may be provided for mixing apparatus of any weight.

The mixing apparatus may be raised and lowered by moderate manual force supplied to any convenient point, such as frame 8.011

the materials A tank removed and another tank positioned for mixing, and so on. I claim:

1.Mixing apparatus comprising a stationa ary frame, a movable frame, a mixersu ported thereby including a rotor and a sul;- stantially vertical rotor shaft, a motor on the movable frame connected to the shaft, and a parallel linkage connecting the movtrame to the frame, whereby the 'y he 'moff-l in parallel alignment and from a tank containing mixable into materials, the mixer also including a generally annular deflector located about the rotor, and uprights connecting the deflector to the movable frame.

2. Mixing apparatus comprising a standard, parallel arms pivotally connected to the standard, a movable frame pivotally connected to said arms, a motor in an upward location on the movable frame, and a mixer Supported in a lower position by the movable frame, the mixer comprising a rotor and a vertical shaft connecting it to the motor,

and a deflector structure about the rotor and upright members connecting the deector to the movable frame.

3. Mixing apparatus comprising a stationary standard, upper and lower parallel arms pivotally connected to the standard, a movable frame pivotally connected to said arms, a motor in an upward location on the movable frame, and a mixer supported in a lower position by the movable frame, the mixer comprising a rotor and a vertical shaft connecting it to the motor, and a defiector structure about' the rotor and upright members connecting the deiiector to the movable frame. I

4. A mixing apparatus vfor general commercial mixing, comprising a column adapted for Hoor support, a movable frame, parallel arms pivotally connected to the column and movable frame to guide the latter in substantially vertical movement, a counterweight and a connection therefrom to support the weight olf the arms, movable frame and parts thereon, a motor mounted at an upper position on the movable frame, a shaft extending down from the motor, a rotary turbo-impeller at the lower end of the shaft, a stationary bladed ,deflector about the impeller, and arms extending downward from the movable frame and supporting the delector, the mixer comprising the impeller and deflector being adapted for practically vertical movement into and out of a mixing tank located on the floor adjacent the column.

In testimony whereof I aiix my signature.

JAMES PETERS.
