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 tangency of the round members, centrifugal force is exerted angularly upward allowing the round members and compression spring to expand creating a relatively large resultant angular upward force acting on the screen bed and materials to be separated are thrust in an angular direction toward the discharge end.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
