Abstract
Abstract Apparatus for producing work by vibrations having a particulate material-handling assembly vibrated by a driver which is mounted on said assembly by means of elastomeric bodies, the driver having a rotary eccentric mass which generates vibrations which are transmitted to the assembly along a predetermined line of attack axis. The work-producing vibrations are transmitted along the attack axis by compression of the elastomeric bodies while vibratory excursions other than in the direction of such attack axis are dissipated through flexure of the elastomeric bodies in shear.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
238 words
A vibratory material-handling apparatus comprising: a particulate material-handling assembly to be vibrated including a member to receive material and a driver-supporting frame attached to said member, means for resiliently supporting said assembly, a driver carried by said frame having motor means with a rotatable shaft coupled to drive an eccentric rotating mass to generate vibrations for exciting said member into work producing vibratory movement, resilient means providing the sole support for said driver on said frame for transmitting said vibrations to said member along a predetermined line of attack axis comprising a pair of elastomeric bodies disposed on opposite sides of said driver with said bodies generally aligned along said line of attack axis, each of said elastomeric bodies having oppositely facing end surfaces generally normal to said line of attack axis, one end surface of each body being secured to said frame and the other being secured to said driver with the axis of said motor means shaft disposed generally parallel to the planes of said end surfaces whereby said vibrations are transmitted to said member through compression of said elastomeric bodies, each of said bodies having exposed edge faces defining the boundaries of a shear plane disposed substantially perpendicular to said line of attack axis, said driver having no force-transmitting connection with said assembly other than said resilient means whereby vibrations other than along said attack axis are dissipated through shear flexure of said elastomeric bodies.
Claim 2
Dependent Claim
238 words
A vibratory material-handling apparatus comprising: a particulate material-handling assembly to be vibrated including a member to receive material and a driver-supporting frame attached to said member, means for resiliently supporting said assembly, a driver carried by said frame having motor means with a rotatable shaft coupled to drive an eccentric rotating mass to generate vibrations for exciting said member into work producing vibratory movement, resilient means providing the sole support for said driver on said frame for transmitting said vibrations to said member along a predetermined line of attack axis comprising a pair of elastomeric bodies disposed on opposite sides of said driver with said bodies generally aligned along said line of attack axis, each of said elastomeric bodies having oppositely facing end surfaces generally normal to said line of attack axis, one end surface of each body being secured to said frame and the other being secured to said driver with the axis of said motor means shaft disposed generally parallel to the planes of said end surfaces whereby said vibrations are transmitted to said member through compression of said elastomeric bodies, each of said bodies having exposed edge faces defining the boundaries of a shear plane disposed substantially perpendicular to said line of attack axis, said driver having no force-transmitting connection with said assembly other than said resilient means whereby vibrations other than along said attack axis are dissipated through shear flexure of said elastomeric bodies.
Claim 3
Dependent Claim
29 words
A vibratory material-handling apparatus as recited in claim 1 wherein said material receiving member consists of a trough along which particulate material is moved by said work-producing vibratory movement.
Claim 4
Dependent Claim
35 words
A vibratory material-handling apparatus as recited in claim 1 wherein said motor means includes an electric motor and said eccentric mass comprises at least one weight mounted eccentrically of the axis of the motor shaft.
Claim 5
Dependent Claim
36 words
A vibratory material-handling apparatus as recited in claim 3 wherein each elastomeric body is comprised of a plurality of spaced elastomeric units which units are aligned generally parallel to the axis of said motor means shaft.
Claim 6
Dependent Claim
31 words
A vibratory material handling apparatus as recited in claim 1 wherein each of said elastomeric bodies is comprised of at least two elastomer bloCks with a plate laminated between adjacent blocks.
Claim 7
Dependent Claim
23 words
A vibratory material-handling apparatus as recited in claim 5 wherein said plate is aluminum and projects beyond the exposed edges of the blocks.
Claim 8
Dependent Claim
230 words
A vibratory material-handling apparatus comprising a first mass including a material-handling assembly having a feed path for moving material in a given direction, means mounting said first mass for free vibratory movement, a second mass including a rotatable shaft having an eccentric weight attached thereto whereby rotation of said shaft creates a rotating force vector transmitted by said shaft to said second mass, means for continuously rotating said shaft, and a pair of elastomeric members disposed on opposite sides of said second mass for connecting said second mass to said first mass, said elastomeric members providing the sole support for said second mass, said elastomeric members being arranged in a plane which includes said feed path and having parallel opposite end surfaces for engaging said first and second masses with the axis of said shaft extending generally parallel to the planes of said end surfaces whereby generally linear vibratory movement is transmitted to said first mass in a driving direction normal to said end surfaces through the compression of said elastomeric members, said second mass having no force-transmitting connection with said first mass other than said elastomeric member and the relative dimensions of said elastomeric members being such that vibratory forces generated in said second mass other than in said driving direction are substantially dissipated through the flexure of said elastomeric bodies in a direction normal to said driving direction.

Dependent Claim
230 words
A vibratory material-handling apparatus comprising a first mass including a material-handling assembly having a feed path for moving material in a given direction, means mounting said first mass for free vibratory movement, a second mass including a rotatable shaft having an eccentric weight attached thereto whereby rotation of said shaft creates a rotating force vector transmitted by said shaft to said second mass, means for continuously rotating said shaft, and a pair of elastomeric members disposed on opposite sides of said second mass for connecting said second mass to said first mass, said elastomeric members providing the sole support for said second mass, said elastomeric members being arranged in a plane which includes said feed path and having parallel opposite end surfaces for engaging said first and second masses with the axis of said shaft extending generally parallel to the planes of said end surfaces whereby generally linear vibratory movement is transmitted to said first mass in a driving direction normal to said end surfaces through the compression of said elastomeric members, said second mass having no force-transmitting connection with said first mass other than said elastomeric member and the relative dimensions of said elastomeric members being such that vibratory forces generated in said second mass other than in said driving direction are substantially dissipated through the flexure of said elastomeric bodies in a direction normal to said driving direction.
Claim 10
Dependent Claim
50 words
A vibratory material-handling apparatus as set forth in claim 7 wherein each of said elastomeric members is comprised of a plurality of elastomeric blocks with a rigid but conducting plate being laminated between adjacent blocks, said plates extending in a direction parallel to said end surfaces of the elastomeric member.
Claim 11
Dependent Claim
35 words
A vibratory material-handling apparatus as set forth in claim 8 wherein said plates project laterally beyond the side faces of said blocks so as to provide exposed surfaces on said plates for improved heat dissipation.
