Certain of the deflector blades are formed as sleeves 34 for connection of the cross bars 15 by bolts 16, to support the deflector irrevolublyinproper relation to the impeller.
The weight of the mixer, head 12 and connected parts, is counter-balanced by an adjustable weight 35 sliding in the tubular column 2, and connected to head 12 by a chain 36 running over pulleys 37 and 38. The mixer is raised and lowered by a crank 39 on a shaft 40, mounted in bearings 41 in housing 8, and having a sprocket 42 engaging a' chain 43,,which also runs over an upper sprocket 14: and is connected at one point to head 12.
The head may be releasably locked in position by a clamp, or a set SC1eW l5 threaded into one of sleeves 13 and engaging the corresponding guide bar 11. The screw passes through a slot 46 in housing ,8, and has its head 47 exteriorly accessible to the operator.
While the apparatusis adapted for a great variety of mixing operations, its utility is sufiiciently explained in connection with paint mixing. measured into tanks or tubs such as 50, these being usually mounted on wheels 51, and two, three or more of thetubs are placed about column base 1, which preferably has side recesses to accommodate the tubs, and locate their centers at a radial distance from the column, correspondingpractically to the radial position of impeller shaft 23. With the mixer elevated above the level of the tub tops, frame 3 is swung around to align the shaft axis withthe center ofone of the tubs or tanks, and the mixer is then lowered, by
operation of crank 39, to a desired (adjustable) vertical position, either near the tank bottom, or at an intermediate or upward position therein, depending on the character of materials, or other considerations. The motor is energized to run the impeller at a desired speed, and the materials are quickly and thoroughly mixed; the mixer is then raised, swungover another tank, lowered, and V soon. 7 The tanks or tubs may be changed while mixing is going on in any one of them. Thus by relatively simple apparatus Iprovide for practically continuous mixing operations, exchange of tanks or tubs, etc., with obvious convenience and economy.
When it is necessary to cleanthe mixer, (as for example, when it is to be used in a different mixture or composition) this may easily be done by lowering it into a tankcontaining asuitable cleaning liquid. I prefer ably make the mixer in suchform that it is easily cleaned, and especially avoid sharp corners when material would accumulate and could not easily be dislodged by a brush or scraper. Thus, I provide fillets at where The colors, oils, etc., are
blades 20 join plates 19, and also at the lines of juncture of blades 32 and webs 33.
