A shaker table and a separate bracket are supported, at respective longitudinally spaced points, on said rods for rectilinear reciprocation along the rods. The shaker table is arranged to have a carrier, for articles to be shaken, secured thereto, and a counterweight is secured to the bracket. A pair of timing belts extend around respective gears adjacent opposite ends of the support frame, and the shaker table is secured to the upper run of the belts, with the bracket and the counterweight being secured to the lower run of the timing belts. An adjustable stroke crank means, driven by a motor or the like, oscillates driving gears engaged with the timing belt so that the shaker table and the bracket with the counterweight are reciprocated longitudinally of the rods through equal amplitudes and in respective opposite directions. Thereby, during operation of the shaker, the counterweight substantially balances the shaker table.，下面是Reciprocatory shaker专利的具体信息内容。

权利要求

1. Shaker apparatus comprising, in combination, a support frame; rods carried by said support frame and extending in spaced parallel relation longitudinally of said support frame; a shaker table supported, at longitudinally spaced points, on said rods for rectilinear reciprocation along said rods; a counterweight supported, at longitudinally spaced points, on said rods beneath said shaker table for rectilinear reciprocation along said rods; and driving means interconnecting said shaker table and said counterweight and operable to reciprocate said table and said counterweight longitudinally along said rods in mutually opposite respective directions, whereby, during operation of said shaker apparatus, said counterweight substantially counterbalances the horizontal forces due to rectilinear reciprocation of said shaker table.

2. Shaker apparatus, as claimed in claim 1, in which said driving means comprises endless belt means extending longitudinally of said support frame; and means operable to oscillate said endless belt means through a predetermined amplitude of movement; said shaker table and said counterweight being secured to respective opposite runs of said endless belt means.

3. Shaker apparatus, as claimed in claim 2, in which said endless belt means comprises at least one timing belt trained over and meshing with gears adjacent respective opposite ends of said support frame; said driving means oscillating at least one of said gears through a predetermined arc of angular movement.

4. Shaker apparatus, as claimed in claim 2, in which said endless belt means comprises a pair of laterally spaced endless timing belts extending longitudinally of said frame; a pair of driving gears rotatably mounted adjacent one end of said support frame and meshing with said timing belts; and a pair of idler gears rotatably mounted adjacent the opposite end of said support frame and meshing with said pair of timing belts; said driving means oscillating said driving gears conjointly through a predetermined arc of angular movement.

5. Shaker apparatus, as claimed in claim 4, including means rotatably mounting said idler gears for adjustment toward and away from said driving gears to adjust the slack in said timing belts.

6. Shaker apparatus, as claimed in claim 4, in which said driving means comprises a crank arm secured to a shaft conjointly mounting said driving gears; a link pivotally connected at one end to the free end of said crank arm; a driving pulley; drive means operable to rotate said pulley; a crank plate secured to said pulley; and a pin on said crank plate eccentric to the axis of rotation of said pulley and connected to the opposite end of said link.

7. Shaker apparatus, as claimed in claim 6, including means mounting said crank plate for adjustment raDially of said pulley to adjust the stroke of said crank arm.

8. Shaker apparatus, as claimed in claim 7, including an indicator plate adjacent an edge of said crank plate and containing indicia cooperable with another edge of said crank plate to indicate the stroke of said crank arm.

9. Shaker apparatus, as claimed in claim 4, including an upper bracket having a substantially flat surface overlying the upper runs of said timing belt and a pair of legs depending between said timing belts and apertured to receive bushings engaging said rods; means securing said shaker table to the base of said upper bracket; a lower bracket having a substantially flat base and a pair of upwardly extending legs apertured to receive bushings engaging said rods; and means securing said counterweight to the base of said lower bracket and to the lower runs of said timing belts.

10. Shaker apparatus, as claimed in claim 9, in which said frame includes a pair of spaced upwardly extending side walls supporting bearings mounting shafts for said driving and idler gears; a pair of cross members extending between said side walls and connected thereto in longitudinally spaced relation to each other; said rods extending through said cross members; and means anchoring each rod to both cross members.
