Abstract

Abstract A dirt compacting and asphalt compacting roller unit of sufficient weight for utilization in compacting fill dirt introduced into a ditch to fill the ditch, and for utilization in compacting hot asphalt subsequently applied over the previously compacted fill dirt. The roller unit comprises a smooth-surface circumference drum shape roller with concentrically positioned shaft protruding laterally on each side. The roller has two or more detachable dirt compacting plates having multiple exteriorly projecting protrusions which, when the plates are attached to the roller, become the exterior circumference of the roller and act to compact fill dirt when the roller with plates attached is repeatedly rolled over fill dirt within a ditch. When the plates are detached, the smooth-surface circumference of the roller acts to compact hot asphalt when the roller's smooth-surface circumference is repeatedly rolled over hot asphalt subsequently applied over the previously compacted fill dirt. The roller unit additionally comprises an open cube-shape housing frame holding the roller at each side of the roller by securement to the roller's protruding concentric shaft in a manner to permit the roller to rotate. The frame has attachment means attachable to a controllably moveable loading bucket of a self-propelled loader vehicle or optionally attachable to an extension frame means attachable to the loading bucket. The housing frame also houses a tank for water and a water transmission line therefrom to selectively permit the flow of water over the roller for cooling. The housing frame additionally houses one or more scraper brushes and one or more scraper blades, each positioned to be selectively pressured against the roller to remove unwanted matter adhering to the smooth-surface circumference of the roller when the detachable dirt compacting plates are removed and the roller is rotated.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 259 words
A dirt compacting and asphalt compacting roller unit of sufficient weight for utilization in compacting fill dirt introduced into a ditch to fill the ditch, and for utilization in compacting hot asphalt subsequently applied over the previously compacted dirt, the roller unit comprising: a. a smooth-surface circumference drum shape roller with concentrically positioned shaft protruding laterally on each side and rotatably attached at each shaft protrusion to a housing frame, with the roller having three attached detachable plates which are arc-shaped to fit against the smooth-surface circumference of the roller and which each cover one-third of said smooth-surface circumference, and with the plates having multiple exteriorly projecting dirt compacting protrusions; and b. a cube-shape housing frame rotatably holding at each side and from above the roller's laterally protruding shaft in a manner to permit essentially one-half of the roller to be outside the frame, with the frame having front attachment means comprising two spaced notches which accept the leading bottom edge of a controllably movable loading bucket of a self-propelled loader vehicle and rear attachment means comprising two spaced brackets each having a key-shape opening therein to receive and secure a respective chain secured atop the rear of the loading bucket, and with the frame also housing a tank for water and a water transmission line therefrom to manually selectively permit the flow of water from above over the roller along the roller's width, and with the frame additionally housing a scraper brush and blade assembly and a scraper blade assembly, each assembly manually spring pressurable against the roller.
Claim 2
Dependent Claim 259 words
A dirt compacting and asphalt compacting roller unit of sufficient weight for utilization in compacting fill dirt introduced into a ditch to fill the ditch, and for utilization in compacting hot asphalt subsequently applied over the previously compacted dirt, the roller unit comprising: a. a smooth-surface circumference drum shape roller with concentrically positioned shaft protruding laterally on each side and rotatably attached at each shaft protrusion to a housing frame, with the roller having three attached detachable plates which are arc-shaped to fit against the smooth-surface circumference of the roller and which each cover one-third of said smooth-surface circumference, and with the plates having multiple exteriorly projecting dirt compacting protrusions; and b. a cube-shape housing frame rotatably holding at each side and from above the roller's laterally protruding shaft in a manner to permit essentially one-half of the roller to be outside the frame, with the frame having front attachment means comprising two spaced notches which accept the leading bottom edge of a controllably movable loading bucket of a self-propelled loader vehicle and rear attachment means comprising two spaced brackets each having a key-shape opening therein to receive and secure a respective chain secured atop the rear of the loading bucket, and with the frame also housing a tank for water and a water transmission line therefrom to manually selectively permit the flow of water from above over the roller along the roller's width, and with the frame additionally housing a scraper brush and blade assembly and a scraper blade assembly, each assembly manually spring pressurable against the roller.
Claim 3
Dependent Claim 30 words
A dirt compacting and asphalt compacting roller unit as claimed in claim 1 wherein the projecting protrusions of the dirt compacting plates are disc shape and atop respective supporting shafts.
Claim 4
Dependent Claim 44 words
A dirt compacting and asphalt compacting roller unit as claimed in claim 1 wherein the housing frame and extension frame means are one-half inch thick angle iron and the dirt compacting plates and smooth-surface circumference of the roller are one-half inch thick plate steel.
