Abstract
Abstract An apparatus for vibrating a material separator provides selective horizontal and vertical high frequency vibratory forces to the separator. The amplitude of the forces can be individually controlled while the machine is operating. The precise direction of the horizontal force can be set to obtain the desired pattern of material travel over the screen. Also disclosed is a manner in which the vibratory motion caused by the vertical component force can be utilized to prevent screen blinding.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
179 words
Apparatus for transmitting vibrations to a material separator having at least one substantially horizontal screening section including a screen spanning said screening section and an outlet at the periphery thereof comprising, at least one plate having a first branch and a second branch angular to said first branch, first vibrating means transmitting a vibratory force to said first branch, said second branch being connected to the material separator so that said first vibrating means transmits a selective horizontal and vertical force to the material separator, the angularity between said branches determining the amount of horizontal and vertical force, second vibrating means selectively transmitting a primarily vertical vibratory force to the material separator, first control means capable of regulating said first vibrating means while said first vibrating means is in operation, and second control means capable of regulating said second vibrating means while said second vibrating means is in operation so that the horizontal and vertical vibratory forces can be independently regulated while the material separator is operating to obtain the desired movement pattern of the material on the screen.
Claim 2
Dependent Claim
179 words
Apparatus for transmitting vibrations to a material separator having at least one substantially horizontal screening section including a screen spanning said screening section and an outlet at the periphery thereof comprising, at least one plate having a first branch and a second branch angular to said first branch, first vibrating means transmitting a vibratory force to said first branch, said second branch being connected to the material separator so that said first vibrating means transmits a selective horizontal and vertical force to the material separator, the angularity between said branches determining the amount of horizontal and vertical force, second vibrating means selectively transmitting a primarily vertical vibratory force to the material separator, first control means capable of regulating said first vibrating means while said first vibrating means is in operation, and second control means capable of regulating said second vibrating means while said second vibrating means is in operation so that the horizontal and vertical vibratory forces can be independently regulated while the material separator is operating to obtain the desired movement pattern of the material on the screen.
Claim 3
Dependent Claim
39 words
Apparatus for transmitting vibrations to a material separator according to claim 1 having orienting means to vary the direction of the horizontal vibrating force transmitted by said first vibrating means along the substantially horizontal plane of the screening section.
Claim 4
Dependent Claim
30 words
Apparatus for transmitting vibrations to a material separator according to claim 1 wherein first cushioning means are provided between said first vibrating means and said first branch of said plate.
Claim 5
Dependent Claim
25 words
Apparatus for transmitting vibrations to a material separator according to claim 3 wherein second cushioning means are provided between the floor and the material separator.
Claim 6
Dependent Claim
44 words
Apparatus for transmitting vibrations to a material separator according to claim 1 having a vibratory plate depending from approximately the center of a screEning section of the material separator, said second vibrating means selectively transmitting a primarily vertical vibratory force to said vibratory plate.
Claim 7
Dependent Claim
24 words
Apparatus for transmitting vibrations to a material separator according to claim 5 having cushioning means between said vibratory plate and said second vibrating means.
Claim 8
Dependent Claim
50 words
Apparatus for transmitting vibrations to a material separator according to claim 1 having a wiper means extending over a screen spanning said screening section and located proximate said peripheral chute to direct the material toward said chute when said vibrating means are adjusted to maintain the material on the screen.
Claim 9
Dependent Claim
44 words
Apparatus for transmitting vibrations to a material separator according to claim 7 wherein said wiper means is adjustably maintained on a post means, said post means extending upwardly through said screening sections and having threads thereon to effect the adjustment of said wiper means.
Claim 10
Dependent Claim
27 words
Apparatus for transmitting vibrations to a material separator according to claim 1 wherein the said angle between said branches is in the range of 40* to 80*.
