- MULTIPLE SOLUTION STIRRER Filed May 9, 1958 /Iu HH Ill' """ll INVENTOR. HARRY D blzowN BY n United StatesM Patent O This invention relates to a solution stirring device more particularly for use in chemical laboratories, and has for its principal object the provision of a simple and highly eiiicient multiple stirring device for simultaneously stir ring a plurality of solutions from a single power source, by means of which solution containers such as laboratory beakers can be quickly, easily and safely placed in or removed from stirring position while the stirrer is in operation. v
Another object of the invention is to provide means for detachably supportingV a conventional glass laboratory stirring rod at an angle to the axis of stirring rotation so as to provide a maximum stirring action without it being necessary to bend or deform the rod.
Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and efficiency, These will become more apparent from the following description.
In the following detailed description ofthe invention, Y
reference vis had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description.
In the drawing: f
Fig, l is a top View of the improved multiple stirring device; 4 f
Fig. 2 is a front view thereof;
Fig. 3 is a right side View thereof;
Fig. 4 is an enlarged, fragmentary, detail view illustrating a stirring rod clamp as employed in the improved multiple stirring devicegand i Fig. 5 is a top View of the rod clamp, taken on the line 5 5, Fig. 4. I
The improved multiple stirrer is' assembled in a supporting frame which, as illustrated, comprises two end frame members 16 and 11 which support an elongated top member 12. The end frame members 10 and 11 Y are maintained in vertical spaced-apart relation by means of an elongated table member 13 which extends between the side members at approximatelyv one third their vertical height. A hold-down strip 14 is secured to and extends longitudinally of the table member 13 and is spaced from the latter-by means of uniformly separated spacers A plurality of hat, elongated, beaker shelves 16 Vare arranged tto slide transversely of the table member 13 between the spacing members 15. The beaker shelves 16 are maintained in a horizontal plane by means of the hold-down strip 14, and each is preferably provided with Va linger button 17 to facilitate its being drawn forwardly or pushed back on the table member 13.
A horizontal (preferably square) bearing bar 18 ex-l tends between the side frame membersY 10 and 11 above and forwardly of the table-member 13. The bearing bar is secured at its extremities in the side frame members by means of suitable set screws Y19t. A plurality of vertical i' spaced-apart, tubular shaft bearings 20, corresponding ice V:in number to the number of shelves 16, extend thiough and arev supported bythe bearing bar `18. A relatively short stirring shaft '21 is rotatably mounted in each shaft bearing 20 in vertical alignment with the -longitudinal center line of each shelf. terminates at its upper extremity in a grooved belt pulley 22 and its lower extremity in `a rod clamp 23.
The rod clamps are formed from sheet metal bands which are folded in a U-shape about the stirring shafts, and secured thereto by means of key pins 24. Each of the folded'blanks extends radially from its stirring shaft to form two opposed clamping ears which may be clamped together by means of a suitable clamp bolt 26. An inclined, semi-cylindrical socket 25 isl formed in each clamping ear which cooperates to form a rod channel to receive a glass laboratory stirringrod 27. The axis of each of the rod channels is positioned at an acute angle to the axis of the adjacent stirring shaft so as to place the glass stirring ro'din an eccentric, inclined stirring position to Yobtain a maximum stirring effect from the conventional straight glass rod.
The stirring action is obtained from an electric motor 29 mounted on the top member 12. The motors shaft indicated at 36 extends downwardly from the motor to Vdrive a double grooved motor pulley/'31 from which endsimply supporting it on one hand while theshelf is pushed-back and then lowering it, from the stirring rod.
While aspecicform of the improvement'has been "i Y described and illustrated herein, itis to Abe understood that the same may bevaried within the scope of the ap- -pended claim, without departing from the spirit of the invention.
" Having thus described the invention, what is claimed and desired secured by Letters Patent is:
A multiple.jsolutionmixer comprising: two upstandi ing end members; an elongated bearing bar extending horizontally between and supported by said end members; a plurality of vertical spaced-apart shaft bearings mounted on said -bearingban a stirring shaft mounted i .'ber secured at its extremities to said end members and v extending between the latter below and rearwardly of said bearing bar; a plurality of spaced-apart flat shelves supported on and arranged to slide horizontally and transversely of ysaid table member so that they may be drawn forwardly to a position below said stirring elements; ahold-down strip slidably securing said shelves on A said table member rand means for simultaneously rotatingallof said shafts; said means for simultaneously rotating all of said shafts comprising: an elongated'top member secured on and extending between said endmembers above said bearing bar; avmotor supported on said top memberfa motor shaft driven by andv extending i (References on following page) Each stirring shaft 21 The.
