ll atented lli eem 'lltlt, "llltlil dm Iterial nu ttlh'ltltt pulley 9, are niorahle relatively to the sitter or hoot hut are carried by said her 3 through the hrachcts l2, 13. in this drive eonneetion the idlers may he adjusted to o leading on or oit' the pulley 18 at "ed angle Witlunit hating the Whole helt interfere With the uniform orhital trarel or gyration of ti sitter 8. ltotation at the pulley and through it of the ehaitt h 'Wmilril normally aeeorn h no eontrol or dririnp; action as to the at. er 3. However, mounted on the shaft 6 are a pair of gyrator derioee each inehidinp; a til-shaped the weight it) coactinpg with an opposing tlshaped holder 20 for fully embracing; the ehatt 6. Fast on the shaft 6 is a yoke 21 carrying a pair ot guides; 22, which yoke 21 and guides '22 form a third li -shaped derice. The guides eoaet "with the anti- ;trietion rollers 23 mounted. in the cages 23 in the tlyn eight device 19 permitting ready lial tra fl oi? this ilyweipght it) as to the u all: l. he til d riee carries the Weight 19, While the We. at it) carries the til device 20. The eent ltupnl action oi the flyweight i9 is resisted. hy the compression spring 24 acting hetween the ti devices 20, EZL'While the maximum throw of the fiyweight may he positively adjusted by the not 525 on the stop stern. 26 carried lay the tl-shaped holder 20.
This travel in an orhit oi the rotating shatt vdriving means for ley normally gyratable with the body, a belt,
6 carries with it the non-rotating sifter 3 giving the shaking action to effect the treatment of the stock. Accordingly, in the normal operation of the machine the pulley 9 is gyrating. However, the Whips of the reaches of the belt 10 are minimized in the modified movements of the guide pulleys 11 for the roller 15 travels to and fro instead of in an orbit like pulley 9. Thus there 1s distribution of the travel of the pulley 9 in its effect upon the belt 10 from the. driving source of the fixed pulley l8.
In the driving and control of the sifter there is no rigid connection between the sifter and its building or supporting structure, and the control lunges or vibrations of the sifter may not be transmitted as concussion to disturb the building, or react to modify the gyratory travels.
The maximum throw adjustment of the sifter may be readily modified by adjusting the stem 26 or the loading of the fiyweights 19, while a variation in the stock loading of the sifter 3 will be taken up in the machine travel itself. However, this variation in the load of the sifter need not modify the effec-.
tive action of the sifter with the controlling mass of the flyweights of suflicient momentum to maintain mastery up to the adjustment of the stop 26.
What is claimed and it is desired to secure by Letters Patent is:.
