Vibrating screen apparatus
First Claim
1. A vibrating screen apparatus operated from a power source for separating material by size, said vibrating screen apparatus comprising:
- a frame having side walls and cross braces, said frame being at an incline;
vibrating screen between said side walls;
a tensioning device for stretching said vibrating screen between said side wall;
vibrating bars beneath and adjacent said vibrating screen, said vibrating bars being generally parallel to side walls;
vibrator attached to said vibrating bars to cause vibration thereoff upon activation from said power source; and
isolators mounted between said cross braces and said vibrating bar to allow said vibrating bar to vibrate and to help prevent noise from said vibration.

Abstract
A vibrating screen apparatus for sizing materials is shown that has a minimum of moving parts therein. A vibrating motor is mounted below longitudinal vibrating bars. The vibrating bars are set on air mounts, which air mounts are between the vibrating bars and cross braces connected to the frame. The vibrating bars press against the underside of a vibrating screen to form a crown therein when the air mounts are inflated. The vibrating screen is stretched between the sides of the frame by tensioning rails. A shroud over the top of the frame is secured in place. Multiple size materials can be produced by stacking multiple vibrating screen apparatuses.

10. A method of operation of a vibrating device for separation of materials into different sizes, said method including the following steps:
-
setting said vibrating device at an incline;
tensioning a vibrating screen between side walls of said vibrating device;
inflating air mounts below longitudinal vibrating bars to form a longitudinal crown in said vibrating screen;
causing said longitudinal vibrating bars to vibrate and hence said vibrating screen to vibrate;
feeding said materials onto an upper end of said vibrating screen;
collecting said material that flow through said vibrating screen, which materials are less than a predetermined size; and
discharging said materials out of a discharge end if said materials did not flow through said vibrating screen, which said materials are larger than a predetermined size. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
