Arthur P. Jorgenson, Racine, Wis., assignor, by mesne asignments, to Landon P. Smith, Inc., Irvington, N. J., a corporation of New Jersey Application February 1, 1937, Serial No. 123,439 ‘ 3; Claims. (Cl. 259-108) This invention relates to devices for stirring, apparatus shown in Fig. 1, taken at the plane mixing, or blending paint or other liquids by di rect action upon such paint or liquid in a con tainer. 5 The invention resides in a form. of apparatus in which an electric motor, or other suitable source, of power, is provided with rigid bai?e sup portswhich bear opposing ba?les at their ends and in which the rotating shaft of said motor 10 or power source connects with a shaft disposed between the baiile supports, upon which shaft is carried an ‘impeller or impellers. - The motor drives the shaft inithe proper direction to throw a liquid which is to be treated against the faces 15 of the opposing battles. 'The whole is arranged for ready portability and, by reason of the fact that the reaction of the impeller is largely ab sorbed by the baiiies, may be provided with sim ple and eiiective clamping means for securing ‘20 the same to the side of a container, preferably in such manner that the baffles forming the lower most part of the apparatus may rest directly upon the bottom of the container. , Portable agitators forv the mixing of paint or 25 other ?uids have‘ been constructed in a‘ wide ‘variety of forms. In the forms heretofore pro posed or used, however,‘ the principal object sought apparently has .been to produce circula tion in the liquid undergoing treatment. For the 30 redispersion of badly caked or settled-out paint the object to be sought is not so much that of circulation of the liquid, but rather that of the grinding or disintegration of the solid aggregates which are loosened or washed away from the 35 cake by the circulating ?uid. Heretofore such an action has been obtained only in large stationary equipment and it has been the custom to return to the factory where such facilities are available paint which has become badly caked through 40 protracted storage. In the apparatus of this in vention, however, a simple and easily portable and easily cleaned apparatus is provided which produces, in addition to an active circulation of the fluid, an impact disintegration of aggregates 45 suspended therein. ' The apparatus of this invention is best de scribed by reference to the accompanying draw ings, wherein— Fig. 1 is a side view of an apparatus of this 50 invention, shown mounted in position in a typi cal container, portions of the latter being broken away; Fig. 2 is a. fragmentary end view of a part of the apparatus shown in Fig. 1; ‘55 Fig. 3 is a section, looking: upwardly,v of the Fig. 4 is a section taken downwardly of the apparatus shown in Fig. 1, taken at the plane 4-4; Fig. 5 is a sectional view, looking downwardly, 6 taken at the plane 5-—5 of Fig. 1, showing in de tail the construction of an auxiliary impeller; and Fig. 6 is a side View in detail of the impeller shown in Fig. 5. ‘ 10 Referring to Fig. 1, there is shown one form of apparatus embodying this invention. The ape paratus there shown comprises a motor I, for fur nishing power for operation thereof. The motor maybe of any suitable type, as, for example, a 15 one-fourth H. P. single phase induction motor, capable of operating upon ordinary commercially distributed electric power. Secured to the top of the motor I is a convenient grip handle 2 in which there is housed a suitable switch 3 for ,20 starting and stopping the motor. As shown more clearly in Fig. 2, the grip handle 2 is secured to the motor by means of bolts 4. A flexible cable 5 is provided through which the necessary ‘driv ing current is supp-lied. " 25 Rigidlytsecured to the bottom of the motor I is a‘ supporting frame 6, which is held in place by bolts 7, as shown more'clearly in Fig. 1. The frame 6 for all intents and purposes is a rigid portion of the housing of the motor I and may be 30 integrally formed therewith, if desired. Formed as a part of the frame 6 are sockets 8 in which are held the square baffle supports 9. The ba?le supports are elongated, square rods, the ends of which are diagonally slotted to receive obliquely 35 placed baffle plates 10, as shown in Fig. 1 and in greater detail in Fig. 4. Slidably mounted upon one of the ba?ie sup port rods 9 is the mounting clamp l I, which is provided With a suitable clamping screw 12 to 40 which there is attached a handle lit. The clamp is shown in Fig. l in position on the side of a typical container 15. To provide the sliding con nection with ba?ie support rod 9, the clamp is 45 provided with an integrally formed head l4 through which a square hole passes and in which the square rod 9 is slidably received, as is shown clearly on the right-hand side of Fig. 3. This arrangement, particularly in view of the peculiar 50 interior con?guration of the clamp H, as shown in Fig. 1, permits the apparatus to be clamped to the rim of a variety of’ heights, sizes, and forms, of, containers. The clamp ll insures re tention of the apparatus in a vertical position, 55 ‘ ‘2,115,956 2 . while the weight of the apparatus is borne di rectly by the bottom of the container upon which rests the lower ends of the baffles I0. The moving parts of the apparatus are at tached directly to the shaft of the motor I, al though supplementary bearings may be provided, if desired, and are composed of a coupling I6 and an elongated square impeller shaft II. The shaft I’! bears at its lower end an impeller I8, 10 which is mounted in a slot cut diagonally across the end of said shaft IT. The length of shaft I1 is so adjusted that the lower edge of the impeller I8 is slightly above the lower ends of the baffle plates I0, so that the rotating parts will clear the 15 surface upon which the apparatus rests. ‘ In addition to the impeller I8 there is posi tioned on the shaft I‘! an auxiliary impeller I9, which is composed of a pair of blades 20 and 2I secured to a tubular hub 22. Referringto Fig. 1, 20 it will be noted that the square shaft I1 is pro vided with a plurality of notches 23 disposed along its length. An inwardly projecting lug on the upper edge of the blade 20 is arranged to be received in the notches 23 when turned to the 25 position shown in Fig. 5. Due to the shape of the notches 23 and the direction of rotation of the shaft II, the lug on blade 20 is engaged in the notch 23, thus holding the auxiliary impeller I9 securely in place while the apparatus is in op eration. If it is desired to move ‘the auxiliary impeller to one of the other notches 23, this may be accomplished by turning the impeller I9 one eighth of a turn clockwise, as viewed in Fig. 5, whereupon the impeller I9 may be shifted ver tically to any of the other positions desired and again engaged in a notch 23. Adjustability of the auxiliary impeller I9 is desirable by reason of the variation in sizes of containers which may be employed to hold the paint or liquid under going treatment. Paint being treated in a one gallon container would call for'anappropriately lower position of the impeller than paint under going treatment in a ?ve gallon container ap proximating in dimensions the one shown in Fig. 1, while some containers may call for shifting the impeller I9 to the topmost notch where it is re moved entirely from contact with the liquid. In operation, the shaft IT and impellers at tached thereto rotate in the direction shown by to the arrow in Fig. 4. In so doing it will be noted that the impeller I8 sweeps in a direction which may be de?ned by pointing out that it ?rst crosses a line connecting the remote edges 24 of the ba?les I0 and then in passing onwardly in its path it crosses a line connecting the near edges '25 ‘of the baffles I0. The parts are arranged in relatively close proximity to one another and the impeller I8 is driven preferably at a speed of ap proximately 1000 to 2000 R. P. M. Under these conditions any lumps or fragments of caked or settled paint which come into the path of the impeller I8 are struck a blow of high intensity or are driven against the baf?es with great force, 65 sufficient to disintegrate and redisperse them. In accomplishing this action the ba?les appear to play an important part and, preferably, should be placed obliquely, as shown, since in an ap paratus not including such baffles very markedly 70 inferior results are obtained. The baffles further play an important part in absorbing a large part of the reaction of the impeller, thus relieving the support of the heavy torque which would other~ wise be imposed thereon and making possible the use of the simple sliding clamp II for support. In a typical instance of use of the apparatus of this invention, ?ve, gallons of paint, held in a container similar to the one shown in Fig. l and designated by the numeral I5 and which has been held in storage until badly settled, is opened. An almost solid layer of appreciable depth will be found in the bottom of the container. The ap paratus of this invention is thrust into the con tainer and the clamp II adjusted to the rim of the container and clamped in place by means 10 of the handle I3 on the clamping screw I2. The lower parts of the apparatus, including the baffles I0 and the impeller I8, will then be found to be resting upon, or partially penetrating, the solid layer held in the container. The apparatus is 15 then connected to a source of electric power and the switch 3 thrown to close the circuit. Shaft ' I1 and the impellers carried thereby are immedi ately placed in rotation and the apparatus, by reason of the sliding connection with the head 20 I4 of the clamp I I, immediately starts to descend, quickly'reaching a position in the lower part of the container, as shown in Fig. 1. Unless the paint is unusually obstinate, after operation for approximately two minutes the entire contents of 25 the container will be found to be uniformly dis persed. In particularly obstinate cases the han dle I3 may be loosened and the apparatus moved once or twice during the treatment. The apparatus of this invention, as will be ob served from the above description, in addition to being novel is‘ simple, convenient in use, and high ly effective. Its simple construction lends itself well to rapid and easy cleaning, an important _ feature in any device of this nature. While this invention has been described with the aid of drawings and description setting forth one speci?c embodiment thereof and the manner of its use, it is intended that the protection to be granted hereon be not unnecessarily limited thereby, but 40 that such protection extend to the full limits of ‘the advance disclosed and claimed herein.
