Abstract
A vibratory vectored thrust shaker for separating solid materials from fluids has a base frame and a screen bed support frame carrying a mesh screen supported horizontally above the base frame by resilient supports. An eccentrically weighted vibratory shaft is rotatably mounted transversely between a pair of side rails secured at one end to the screen bed support frame near its discharge end which extend upward therefrom at an acute angle to horizontal. A first resilient round member is mounted at one end of the vibratory shaft. A drive motor mounted on a spring biased hinged mounting bracket connected to the base frame has a second resilient round member mounted on its drive shaft which is engaged in spring biased relation with the first round member. As the weighted portion of the vibratory shaft rotates to the point of tangency of the round members, centrifugal force is exerted angularly downward to compress them together and compress the hinged mounting bracket such that the angular downward force is substantially absorbed and relatively little movement is imparted to the screen bed. As the weighted portion of the vibratory shaft rotates to a point opposite the point of tangenc…
