6402252, Jun 11, 2002

Filed:

Dec 10, 1999

Appl. No.:

09/459126

Inventors:

Wayne E. Dickson - Tecumseh OK

Assignee:

Dickson Industries, Inc. - Tecumseh OK

International Classification:

E01C 2316

US Classification:

299 396, 404 94

Abstract:

A road-cutting apparatus for creating grooves or impressions in a road surface. The apparatus comprises a tool carrier with a rotatable cutter positioned adjacent thereto. A positioning control arm is hydraulically actuated to place the cutter in an operating position just above the road surface, and an operating control arm is hydraulically actuated to move the cutter into and out of cutting engagement with the road surface. The cutting is automatically carried out in response to a signal generated as a result of the distance traveled along the road surface by the apparatus. The road-cutting apparatus also comprises a transport wheel which can be placed into engagement with the road surface such that the cutter is spaced therefrom for transport of the apparatus to a desired location for cutting the grooves or impressions and raised above the road surface for the cutting operation.

International Classification:

B24C 900

US Classification:

51424

Abstract:

A surface blasting apparatus for treating a surface with abrasive, cleaning dust and debris from abrasive rebounded from the treated surface so that the abrasive may be reused, and separating the debris from the air. Air and debris flow through abrasive rebounded from said surface and through a baffle system which prevents abrasive flow therethrough. A row of magnets is positioned adjacent the baffle system for receiving and arresting abrasive exiting an abrasive return chute. A mechanical conveying system lifts abrasive upwardly so that it falls toward an abrasive storage hopper. The abrasive falls in the form of a curtain through which air exiting the baffle system passes. The air and dust contained therein enter a prefilter in a first cleaning chamber and heavy dust falls downwardly therefrom. The air flows from the prefilter into a second cleaning chamber where it is filtered so that light dust is removed therefrom and falls downwardly. Large debris is also removed from the abrasive and discharged to the first cleaning chamber.

International Classification:

B24C 700
B24C 900

US Classification:

51424

Abstract:

An improved surface blasting apparatus for cleaning a surface to be treated by throwing abrasive against the surface at high velocity, then recovering and cleaning the abrasive for reuse. The abrasive rebounding from the treated surface is directed against a magnetic receiving member around which a quantity of the ferrous abrasive forms a protective envelope, with additional high speed abrasive striking said envelope and consequently losing kinetic energy. Means is provided for removing debris from the abrasive by entraining the debris in a flow of air through the apparatus. The debris is separated from the air stream by cyclonic rotation in a dust collector. An alternate embodiment includes a deflector plate to prevent the undesirable escape of abrasive forward of the apparatus. Another embodiment provides for a weighted roller with sharp spikes protruding radially outwardly therefrom to puncture surface coatings which are difficult to remove by normal blasting procedures. A further embodiment utilizes a belt conveyor to lift the abrasive and carry it back to an abrasive storage compartment for reuse rather than using a rebound directing device.

Wayne E. Dickson - Tecumseh OK

Dickson Industries, Inc. - Tecumseh OK

International Classification:

B60P 100

US Classification:

414537

Abstract:

A ramp assembly for trailers which includes a pair of elongated, parallel ramp plates reciprocably supported in tracks under the bed of a trailer. An arresting cam assembly is mounted on the rear of the trailer, and includes a control handle which is connected to, and rotates, a cam rod which carries, and is keyed to, a plurality of spaced cam plates. These cam plates are rotated with the cam rod to bring the lobes of the cam plates against the ramp plates, forcing them into a locked status against the underside of the bed of the trailer. In another rotational position of the cam plates, the ramp plates can be pulled horizontally outwardly from the trailer bed to an inclined loading position, but a cusp on each of the cam plates functions to engage the ramp plates and prevent them from being pulled completely free of the trailer bed.

US Classification:

Abstract:

A road surface treating apparatus including a wheel-supported framework having forwardly extending arms pivotally carried thereon. The arms have a transversely extending tool bar mounted to their forward ends. A tool-supporting frame is detachably and adjustably mounted on the tool bar. A cutter drum housing is pivotally mounted on the tool-supporting frame for floating pivotation about a horizontally extending, fore-and-aft axis to facilitate side-to-side rocking movement of the drum housing. A cutter drum is rotatably mounted in the housing and carries circumferentially spaced rows of cutter blades each mounted for rotation about a horizontal axis. A pair of horizontally spaced, shock absorber units is connected between the housing and tool-supporting frame to damp and smooth the side-to-side rocking movement of the housing and the cutter drum mounted therein.

International Classification:

B24C 900

US Classification:

51424

Abstract:

A surface blasting apparatus including a wheel mounted chassis carrying a detachably mounted blasting head assembly. The blasting head assembly includes a housing enclosing a blasting wheel mounted for rotation about an axis extending parallel to a surface to be cleaned. The housing further includes a return chute through which abrasive returns after impacting such surface. A baffle assembly and magnetic arresting assembly cooperate to clean the abrasive particles by air washing. The air is then directed through a gravitating curtain of abrasive particles at a second cleaning location for further cleaning. The dust and debris laden air is then passed through a cyclonic separator and filtering system to clean the air prior to atmospheric discharge. Variously sized blasting head assemblies can be interchangeably mounted on the chassis for accomplishing various types of blast cleaning operations.
