AGITATING DEVICE Filed Feb. 25, 1955 SAMUEL .BRO/www BY Sal/42%( 14 TTOE NE Y United States Patent AGITATING DEVICE Samuel M. Broadwin, NewYvol-lt, N. Y. Application February 25, 1955i, Serial No. 490,560

3 Claims. (Cl. 259-72) This invention relates to an agitating device which 'is designed to agitate various liquids which are used in laboratory procedures such as the Kahn test, Wasserman test, and similar laboratory examinations.

In laboratory procedures of the character described it is necessary, at some stage of the method, to agitate the container containing the test material. Some procedures call for axially moving the container for Ia considerable period of time while others call `for arcuately moving the container. Some tests call for both types of movement. Y

The apparatus used for the above purposes has been costly. Furthermore no device has been heretofore manufactured which would produce either axial or 'arcuate movement at the selection of the operator.

The agitating of this device, as produced by the instant invention, is either axial or arcuate at the discretion of the operator. The device is relatively inexpensive to manufacture and gives substantially trouble-free operation.

Briefly stated the agitating device of this invention comprises, in combination, a supporting element and a supported element yieldably secured thereto. Means are provided to move the supported element reciprocatingly.

In the preferred modication of this invention the supported element may be selectively moved either axially or arcuately at the discretion of the operator of the device.

The invention will be further described by reference to the accompanying drawings.

Fig. 1 is a sectional view taken longitudinally through the agitating device of this invention.

Fig. 2 is a sectional View of the agitating device of Fig. l taken along lines 2 2 of Fig. l.

Fig. 3 is a plan view of the agitating device of Fig. l.

Fig. 4 is a perspective detail view of the actuating member and guide member of this invention.

Fig. S is a diagrammatic view of the means used to operate the agitating device of this invention.

Referring to the principal form of this invention `as shown in the drawings the 4agitating device 10 has a supporting element 11 and a supported element 12. A plu rality of yieldable supports 13, which are preferably metal springs covered with rubber or similar resilient material, join supporting element 11 to supported element 12. Supports 13 are located at the corner portions of element 11.

Motor 14 bears shaft 18 which has wheel 15 secured thereto. Shaft 16 is secured to Wheel 15 by pin 17.

Actuating member 20 is secured to shaft 16. Holding member 22 is secured to actuating member 20 and is held in place thereon by screw 21. Shaft 23 is integral with holding member 22 and tits into recess 23a in supported element 12. Support 24 bears against the lower side of recess 23a.

Shaft 23 is threaded at its upper end and bears screw 25 thereupon.

Guide 26 is provided with and arcuate.

slot 27 which is both axial Guide 26 is pivotally secured to support- `ICC ing element 11 by

pins

29 and 30. Pin 29 is permanently secured to supporting element 11 by nut v29a while'l pin 30 Ais removably secured thereto.y Handle 31 is providedto move pin 30 out ofengagementwith recess 31 ing,36 in element l12. Guide 26 is disposed over open# ing 36.

Element 11 is provided with a raised door portion 37 wherein opening 36 is provided while element 12 has a iloor 40 which serves as a container holding member. Slidable guide 38 may also be provided movable and secured to ears 39 upon element 12.

The speed of operation of the device may be controlled by conventional rheostat means and on-olf operation can be provided by use yof conventional switch means.

The operation of the device will now be explained.

When it is desired to produce axial movement of element 12 with respect to element 11 guide 26 is secured to element 12 by pin 30 resting in recess 31. With this arrangement the rotation of wheel 15 of motor 14 will reciprocatingly move `actuating member 20. The period of reciprocation of shaft 16 is such that actuating member 20 will not move past the horizontal point of slot 27 of guide 26. Since slot 27 is only axial at that point, and since actuating member 20 is partially disposed within slot 27 which limits the type of movement produced the movement of element 12 with reference to element 11 is only axial. Element 12 may move with respect to element 11 even though secured thereto because supports 13 are yieldable.

When arcuate movement is desired pin 30 is removed from recess 31 and guide 26 pivoted about pin 29 until pin 30 ts into recess 32. When this is accomplished actuating member 20 moves within the arcuate portion of slot 27 between

points

40 and 41. Thus arcuate movement of actuating member 20 is produced which is transmitted to element 12.

The foregoing specific embodiments of this invention as set forth in the specification and drawings herein are for iilustrative purposes and for purposes of example only.

Various changes and modifications may obviously be made within the spirit and scope of this invention V4and would occur to those skilled in this art.

I claim:

l. An agitating device comprising, in combination, a supporting element having a raised door portion provided with a longitudinal opening therein, a supported eieinent having a container holding member thereupon, a plurality of yieldable supports securing said supporting element to said supported element, a pivotally movable guide member secured to said supporting element above said longitudinal opening provided with a longitudinal slot, means for holding said guide member against pivotal movement, an actu-ating member secured to said supported element and disposed within said guide member, and means for reciprocatingly moving said actuating member.

2. An agitating device comprising, in combination, a supporting element having a raised door portion provided With a longitudinal opening therein, a supported element having a container holding member thereupon. a plurality of yieldable supports securing said supporting element to said supported element, a guide member secured to said supporting element above said longitudinal opening provided with an arcuate slot, means for pivotally positioning said guide member to said supporting element, an actuating member secured to said supported elementand partially disposed within said guide Patented Aug., 7,l 1956 r f f. f 2,757,908

member, and means for reciprocatingly moving said actuating member.

3. An -agitating device comprising, in combination, a supporting element having a raised floor portion provided with a longitudinal opening therein, a supported element having a container holding member thereupon, a plurality of yieldable supports securing said supporting element to said supported element, a pivotally movable guide member secured to said supporting element above said longitudinal opening and provided-with an axial and arcuate recess, means for rigidly positioning said guide member against pivotal movement upon said sup- 4 porting element, an actuating member secured to said supported element and partially disposed within said guide member, and means for reciprocatingly moving said actuating member so that said supported element may be selectively moved reciprocatingly with respect to said supported element.
