Claim 4

A material stripping apparatus operable to get under one edge of a material secured to a support surface and to provide a blade member to move the material in an oscillating manner about both vertical and horizontal axes to remove same from the support surface, comprising: (a) a main support frame means having an apparatus drive means mounted thereon, said main support frame means having a frame member mounted on said apparatus drive means for movement of said main support frame means; (b) a material lift means mounted on said main support frame means and having a lift plate member moveable in a forward, rearward, up and down motion to lift the material from the support surface; (c) a lift actuator means connected to said material lift means so as to move said lift plate member in the oscillating manner as set forth above (d) an actuator drive means having a cam shaft mounted within a disc cam member connected to a pillow block which is secured to an undersurface of said lift plate member; (e) said lift plate member having a main support plate member with a plurality of forwardly protruding teeth members; (f) said teeth members insertable under the material so as to contact the material and move same upwardly and laterally; (g) a power means mounted on said main support frame means and operably connected to said apparatus drive means; (h) an apparatus control means having a means thereon to control operation of said power means which drives said apparatus drive means in order to drive the entire said material stripping apparatus at desired speed and horizontal direction; and (i) said apparatus control means having a control means connected to said actuator drive means to control speed and operation of said lift plate member during the material lifting and removing steps of this invention.

Claim 5

A material stripping apparatus operable to get under one edge of a material secured to a support surface and to provide a blade member to move the material in an oscillating manner about both vertical and horizontal axes to remove same from the support surface, comprising: (a) a main support frame means having a pair of spaced, parallel sidewall members with upper aligned surfaces thereon; (b) a power means and a material lift means mounted on said main support frame means; (c) a lift actuator means operably connected to the material lift means; (d) said material lift means having a lift plate member projecting forwardly from said main support frame means supported on said support surfaces and operable to move in a forward, rearward, and up and down motion to lift the material from the support surface; and (e) said material lift means includes a bracket member secured to said lift plate member, a pillow block secured to said main support frame, and a rod member having opposite ends thereof pivotally connected to said pillow block and said bracket member to maintain contact said lift plate member with said support surfaces of said sidewall members.

Claim 6

A material stripping apparatus operable to get under one edge of a material secured to a support surface and to provide a blade member to move the material in an oscillating manner about both vertical and horizontal axes to remove same from the support surface, comprising: (a) a main support frame means having a pair of spaced, parallel sidewall members with upper aligned surfaces thereon; (b) a power means and a material lift means mounted on said main support frame means; (c) a lift actuator means operably connected to the material lift means; (d) said material lift means having a lift plate member projecting forwardly from said main support frame means supported on said support surfaces and operable to move in a forward, rearward, and up and down motion to lift the material from the support surface; and (e) said material lift means includes a bracket member secured to said lift plate member, a pillow block secured to said main support frame, and a rod member having opposite ends thereof pivotally connected to said pillow block and said bracket member to maintain contact said lift plate member with said support surfaces of said sidewall members.

Claim 7

A material stripping apparatus as described in claim 3, wherein: (a) said lift actuator means includes a lift plate actuator assembly having a cam shaft rotatably mounted in bearing members secured to opposite ones of said sidewall members; (b) said lift actuator means further includes pillow members each having a cam member with an opening therein, said cam members having said cam shaft connected thereto and mounted said openings; and (c) said pillow members secured to said lift plate member; whereby rotation of said cam shaft and said cam members causes said lift plate member to reciprocate and oscillate to remove the material mounted on the support surface.

Claim 8

A material stripping apparatus as described in claim 4, includes: (a) said lift plate member having a rearwardly extended arcuate curved portion to receive the severed material thereon and to continuously move the subject severed material reawardly to said arcuate curved portion and laterally of said main support frame means.

Claim 9

A material stripping apparatus as described in claim 3, including: (a) said actuator drive means having a cam shaft mounted within a disc cam member connected to a pillow block which is secured to an undersurface of said lift plate member whereby said cam shaft is movable in a circular path so as to move said pillow block vertically and horizontal so as to move said lift plate member to achieve an oscillating movement thereof and the rotation of said cam shaft and the limitation of said rod member engagable with said lift plate member operates to achieve the reciprocating and oscillating motion of said left plate member.
