' To all 20 ho m it may concert hi Be it known that L JAMns D; MOORE, a

and State of North Carolina, have invented certain new and useful Improvements 1n Mechanical Movements, of which the following is .a full, clear, and exact specification. 'This invention relates to: a mechanical movement, and more particularly'to a me- 'chanical' movement forsimultaneously oscillating or agitating aplurality of operative elements. I

The invention has for. its objects toprovide amechanical movement which will uti-V operation, will automatically take up any Wear between the coacting elements, and also to provide a movement which will operate quietly and efficiently. l

The mechanical movementwhich will be particularly for agitating the sieves or grain separating elements on flour m lls, although it'should beidistin ctly understood that the invention 'is notflimited in any way to this particular adaptation.

jThe objects of the invention are can out infthe present instance by means of a membeij fixedbto the drive shaft and providedwith aneccentric groove. This mem= member disposed adjacent thereto and provided with a corresponding groove, the

. groove in the-second membenhowever, being concentric with respect to the inner and outerperipheries of .said member.

Referring now toFigs Q to l, inclusive,;' 7 I the d ailsjof'theconstruction of'the inr-v proved I mechanical movement be: de 1 f scribed- 1 z Thefmeans for changing the rotary motion 00 of the. shaft 20 to an oscillating motion come pr ses-.2 cqll rvm m er 2 1 which" is sec e by a s'etscr flt to theshaft' 20.1; Thisel v 'lar is provided withla 'g'roove-25'whichlfis formed ec en ric with: respect to the 5 center t of the shaft 20, the eocentri:

econd collar 26 is disposed adjacent theed ola f 23glthis collarheing provided wi m 7 meet: eleee rasin a-whe e ception of the shaft 20. The collar 26 is provided with oppositely extending flanges 28 and 29, the flange 29 overlapping an end portion of the collar 23. The main body portion of the collar 26 is provided with a circular groove 30 which is formed concentric to the inner and other peripheries of the collar 26, the diameter of this groove being the same as that of the eccentric groove 25 formed in .the collar 23. A plurality of balls 31 are mounted in the grooves 25 and 30, these balls being retained in the grooves and the collar 26 being maintained in a position adjacent the collar 23 by means of a coil spring 32 which is interposed between the collar 26 and the casing 12. The inner bearing 21 for the shaft 20 is provided with an outwardly projecting shoulder 33, upon which one end of the coil'spring 32 is positioned, the opposite end of this spring being positioned on the peripheral flange 28 which is formed on the collar 26. The oscillating movement of the collar 26 is communicated to the members to be oscillated thereby by means .of connecting links. The screen or sieve 15 is connected to the collar 26 by means of a link 34 which is pivoted at 35 to the collar 26, and atits opposite end passes through a rearwardly extending lug 36 carried by a pivoted member 37 which in turn is pivoted to a bracket 38'securedto the casing 12. The upper end of the member 37 is provided with an outwardly extending strap 39, preferably formed of resilient material, the rear end of the screen being secured to this strap. The bolter 17 is connected to the collar 26 by means of a link 40 which is pivoted at 4:1 to the bolter, and at 42 to the member 26.

Having described the construction of my improved mechanical movement, I will now briefly outline the operation of themovement.

As the shaft 20 is rotated by means of power communicated to the pulley 22, the collar 23 will also be rotated and will com municate oscillating movement in a plane perpendicular to the axis of collar 23 to the collar 26 by reason of the eccentric groove 25, balls 31 and groove 30. The spring 32 forces the collar 26constantly toward the collar 23, thereby retaining the balls in position between the grooves 25 and 30. The

oscillating movement of the collar 26 is communicated to the sieve or screen 15 by means of the link 34, pivoted member 37 and strap 39. This movement is also communicated to. the bolter by means of the link 40 (see Fig. 4:) whichis pivoted at one end .tothe bolter and at its opposite end to the collar 26." This movement reciprocates the link 40 whichin turnoscillates the bolter.

From the above description'it will be seen that the construction has been provided in whiclrany wear between the members 23 and '26 will be automatically taken up by means of the spring 32, and also a construction which, by reasonof the ball bearing driving connection, will utilize a minimum amount of power, and will communicate the movement from the shaft to the operative elements quietly and eliiciently.

It will be evident also from the description that the mechanical movement described and claimed in this specification is equally well adapted for other uses than that particularly shown in Fig. 1., or, in other words, that this movement is capable of general application.

vVhile I have in the above specification described one embodiment of my invention, it

should be understood that the invention is capable of modification, and that modifications and changes in the. construction and in the arrangement of the cooperating parts may be made Without departing from the spirit and scope of the invention, as expressed in the following claims.

1. In a mechanical movement, a rotatable driving member, having an eccentric groove therein, an. oscillatory driven member disposed adjacent said first-named member and having a groove formed therein of a diameter corresponding to the groove in the first named member, and means engaging said grooves for communicating the movement of said sfirst named member to said second,- named member.

2. In a mechanical movement, a rotatable driving member having an eccentric groove therein, an oscillatory driven member disposed in a position ad acent said first-named member and havinga groove therein ofa diameter corresponding to the diameter of the first-named groove, a plurality of balls disposed between said grooves and resilient means for retaining said second-named member in a position adjacent said first-named member. 1

3. In a mechanical movement, a rotatable driving member having an eccentric groove therein, an oscillatory driven member hav-' ing a groove correspondingin diameter to the groove of said; first-named member and having a peripheral flange overlapping said first-named member, a plurality of balls disposed in the said grooves, and resilient means for forcing one of said members in a direction toward the other member.

4. In combination, a driving member having an eccentric groove formed therein, a driven member having a ggroove formed therein corresponding in diameter to the groove of the first-named member, a plurality of balls disposed in the said groove, a plurality ofoperative elements, and means for communicating the oscillating move ment of the second-namedmember to said operative elements.

5. In a mechanical movement, a drive collar, a plurality of balls disposed between said grooves, and means for holding said second-named collar 111 a position whereby said balls will be retained in place between 1 0;

said grooves.

In testimony whereof I affix my signature. 7
