.AG-ITATING- APPARATUS.

Application filed November 30, 1923. Serial No.l 677,766.

To all whom t may concern.'

Be it known that I, JAMES W. KENT, a citizen of the United States, and resident of Brooklyn, in the county of Kings and State 5 of New York, have invented certain new and useful Improvements in Agitating Apparatus, of which the following is a specification.

In the manufacture of ready mixed paints and other substances it is usual and desirable for purposes of economy and for other well established reasons to provide one mixing machine to stir and thereby mix the contents of a number of separate mixing tanks, the tanks with the proper ingredients therein being successively placed in operative rela* tion to the mixing machine, where their contents are stirred to desiredconsistency, and successively moved from the mixing machine to another location where 'cans and other receptacles are lled therefrom for supply to the trade. It is not always feasible, however, to empty the tanks of their contents immediately following movement of the tanks away from the mixing machine after completion of the mixing operation, and as the mixed contents of the tanks soon settle after agitation thereof ceases, the heavier portions of the contents sinking to the bottoms of the tanks and the lighter portions rising to the tops thereof, the result is that the cans or receptacles first filled from a tank that has been allowed to stand some time after the contents thereof have been mixed contains a thick, heavy mixture,

y while cans or receptacles that are last filled contain a much thinner and lighter mixture, which condition manifestly is extremely undesirable. Accordingly it is my purpose to providev means to maintain the mixed con tents of the tanks agitated during the dispensing operation, thereby to assure uniform consistency of the mixture supplied to each can or receptacle.

Tanks of the kind referred to in the foregoing are quite large, having an average capacity of from sixty to one hundred gallons, and it is usual to elevate them by suitable hoisting mechanism to dispose draw-ofi vcocks in their bottoms conveniently above the cans to be filled to facilitate the lling operation. As in the case of the mixing machine, it is desirable Afor purposes of economy and other'wellestablished reasons to provide a single hoisting mechanism yfor elevating thetanks, and accordingly itis my'further purpose to associate withy vsuch s; single hoisting mechanism meansfto facili.- tate attachment and detachment of the latter to and from thetanks and also to ymaintain the contents of the tanks; agitated while the tanks are suspended and whilethecontents .gg thereof are being drawn off. n n

With the foregoing and other purposes in view, my invention consists in the novel features of construction, combination and arrangement of parts, and inthe methods I :,5 employ to accomplish my purposes, as rwill be hereinafter more fully described, illustrated in the accompanying drawings and defined in the appendedfclaims.

In the drawings a Figure 1 isa view yin elevation illustrating a primary mixing station and a dispensing station, a tank in operative relation to a mixing machine being shown at the former stationand a suspended' tank and meansto maintain the, contents thereof agitated being shown aty the, latter station; l l j 1, ,f

In4 Figure 1 of the drawings I have villustrated-'a-mixing machine A of conventional 90 design and wit-hout novelty consisting essentially of a vertical shaft 10 that is rotatably driven and that is verticallyl slidable so that it may be raisedy to vpermit 'a tank to be moved int-o and out of operative relation with the machine, and lowered to dispose@ mixing blades. llf thereon withina tank that has moved intov operative relation with the machine toqmixfthe contents thereof. l;

.Arranged ata 'suitable dispensing location 100 remote from the mixing machine A is a hoisting mechanism B of any preferred type, the same being herein shown as a conventional block and tackle mechanism, also without novelty.

The tanks C, within which paint or other substances are adapted to be mixed by the machine A, and from which the paint or other substance when mixed is adapted to be dispensed when the tanks are elevated by the hoisting mechanism B, also are of conventional design and without novelty, and are provided as is usual with castor wheels 12 whereby they may readily be moved to desired locations. They are also provided with oppositely disposed straps 13 terminating at their upper ends in hooks 1-1 to facilitate `attachment of hoisting mechanism thereto, and with draw-off cocks 15 in their bottoms through which their mixed contents are delivered into cans and other receptacles for supply to the trade.

The process of producing ready mixed paints and other substances by means of the mixing machine A, hoisting mechanism B and tanks C is apparent and 'as follows; First, a tank C with the proper ingredients therein, such as pigment and oil, is moved into operative relation with the machine A and sha'ft 10 of the latter is lowered to submerge the mixing blades 11 'thereof within the tanks contents. Rotation then is imparted to the shaft 10 until the contents of the tank have been thoroughly mixed, when rotation of shaft 10 is stopped and said shaft elevated. An attendant then engages a handle member c with lugs on one of the 'castor brackets on the tank and moves the tank from the mixing machine to a point beneath the hoisting mechanism B, after which the hoisting mechanism is engaged with the tank and the `latter elevated, its contents then being dispensed through its draw-ofi cock 15 into cans and other recepta'cles for supply to the trade.

After lthe contents of a tank have been mixed -it is not always feasible to dispense them immediately, and unless this is done the cans or containers that are filled for supply to the trade do not, for the reasons previously mentioned, contain .a mixture of even consistency. Therefore, I have devised `mechanism to maintain the mixed contents of tanks C agitated while said tanks'are elevated and during the operation o'f dispensing their contents, thereby to overcome the difficulty just mentioned, and

"also vto `provide 'a ready means of attaching "the hoisting 'mechanism to and from lthe tanks.

4The 'mechanism D consists of a channel 'iroiisb'a'se plate luponwhicli is mounted an electric m'o't'o'i 17"carrying on its driveshaft 118 Va worm 19 meshing with a worm wheel 20 on a vert-ical shaft 21 that extends downwardly through said base plate and at its lower end carries suitable agitating blades 22. At its upper end said shaft has bearing in a suitable worm and worm wheel housing 23 that is bolted or otherwise rigidly secured to the base plate,

Rising from the base plate near each end thereof is a pair of supports 24. The supports of each pair being secured respectively to opposite sides of the base plate and being converged with respect to each other towards their upper ends where they are secured to a bar 25 that extends parallel to the base plate above the housing 23 and that has mounted thereon a link 26 with which the block and tackle mechanism B is adapted for detachable engagement. Clamp screws 27 extend through the base plate at the ends thereof whereby said base plate and the mechanism carried thereby may be detachably vsecured to the tanks C through the instrumentality of the hooks 14 thereon.

After the contents of a tank have been mixed by the machine A and the tank moved beneath the hoisting mechanism B the agitating mechanism D is secured to the tank by the clamp screws 27 and the hoisting mechanism engaged with link 26. The tank then is elevated to a convenient height for dispensing its contents into cans through the draw-off cock 15 in the bottom thereof, and while said tank is elevated the motor 17 is maintained in operation to rotate shaft 21 and thus cause the blades 22 to maintain the contents of the tank agitated whereby the mixture supplied to each can or receptacle is of the same consistency.

I claim 1. In apparatus of the class described, a suspended stirring mechanism, means for elevating and lowering said `mechanism in suspension, and means for detachably and operatively connecting the mechanism to a dispensing tank whereby the tank and mechanism may be elevated in operative union to facilitate dispensing and eect stirring of the tanks contents during dispensing.

2. In apparatus of the class described, a block and tackle suspended from a support, a stirring mechanism supported in suspension by said block and tackle whereby said stirring mechanism may `be supported at different elevations, and means for detachably land operatively connecting said stirring mechanism to adispensing tank whereby the tank and said mechanism may be elevated in operative union to facilitate dispensingand effect stirring 4of the tan s contents during dispensing.
