Patent number: 5291955Abstract: The present invention is a self-contained hydraulic hammer which is mounted on a hydraulically mobile frame. The hydraulic hammer is capable of travelling in either forward or reverse directions and is provided with liftable weights to which a tool for digging or breaking up a surface is attached. The hydraulic hammer is equipped with time delay controls which: 1) momentarily stop the travel of the hydraulic hammer as the weights and the attached digging tool free fall from a raised position until the digging tool impacts the surface to be busted up, and 2) cause the hydraulic hammer to resume travel as the weights are again raised in preparation for another impact. The hydraulic hammer rapidly repeats these cycles of impact and travel to break up a surface. Adjustments are provided on the hydraulic hammer for regulating the force of the impact and the distance travelled between impacts in order to match the hydraulic hammer's impact and travel cycles to the break characteristics of the surface to be removed.Type: GrantFiled: March 15, 1993Date of Patent: March 8, 1994Inventor: Thomas P. Clark

Patent number: 5098165Abstract: A roofing materials removal device provides a guide system which secures the device and the operator in position on an inclined roof so that the roof can be traversed at various positions along different travel paths while supported. The removal device comprises a light-weight, durable, wheel supported frame, dual handles for leverage, an electric motor positioned low on the frame to give the device balance and stability. An angled blade reciprocating and riding on linear bearings is connected to spring-mounted tension bars. As the springs force the rear end of the tension bar upward, the forward end of the tension bars pivot downward causing the serrated, leading edge of the blade to slide between the roof covering material and the roof deck. The blade follows the contour of the roof deck dislodging roofing material including nails, roofing felt and shingles. The guide system is positioned on the opposite side of the roof ridge from the removal device.Type: GrantFiled: November 14, 1989Date of Patent: March 24, 1992Inventors: James L. Jacobs, Larry D. Rogers

Patent number: 4828047Abstract: This invention relates to a method and apparatus for collecting subsamples of soils to be tested for infestation and nutrient content. The apparatus includes a sampling tube which is mounted on a collecting wheel which is mounted on a frame. During operation, the apparatus is lifted off the ground. To take a sample, the apparatus is lowered such that the wheel makes contact with the ground. This causes the wheel to rotate, forcing the sampling probe into the ground. The sample empties into the interior of the wheel where it mixes. The mixed sample is later removed and boxed for testing.Type: GrantFiled: March 14, 1988Date of Patent: May 9, 1989Inventor: Charles M. Rogerson

Patent number: 4343513Abstract: The method and power transmission system of this invention for driving a road planar machine has the cutter unit in a positive mechanical drive with the drive shaft of a machine power unit through a hydraulically actuated clutch mechanism. The wheel traction units for the machine are continuously driven from the power unit by hydraulic motors operated by variable volume displacement pumps. A control system for retaining the power unit at a set rotational speed required for a predetermined cutting or planing load is responsive to a drop in the set rotational speed, resulting from the cutting unit encountering an overload, to actuate the variable displacement pumps to decrease the forward speed of the machine without appreciably reducing the rotational inertia force of the cutting unit. If the cutting unit overload is of a short duration or momentary the set rotational speed of the power unit is resumed.Type: GrantFiled: August 25, 1980Date of Patent: August 10, 1982Assignee: Gomaco, Inc.Inventor: Gary L. Godbersen

Patent number: 4284150Abstract: A soil sampling device adapted to be mounted on a motor vehicle. The soil sampling device includes a tubular probe which is operated by means of a hydraulic cylinder and piston. A mechanism linking the probe with the piston causes the probe to swing from a horizontal position to a vertical position and then to move vertically downward into the soil. Upon withdraw from the soil the probe is caused to move vertically upward until clear of the soil and then to swing to a horizontal position with the end of the probe adjacent a sample collecting container. A second hydraulic piston and cylinder serves to eject the soil sample from the probe and into the collecting container. The controls for operation of the device are adapted to mounted at the vehicle operator's station.Type: GrantFiled: July 6, 1979Date of Patent: August 18, 1981Inventor: D. Lynn Davis

Patent number: 4053958Abstract: This device consists primarily of a tool (blade, chisel, or sanding attachment) which is attached to a tool holder. The tool holder in turn is attached by a bearing to a shaft which passes thru a flywheel, the shaft is offset from the center of the flywheel thereby causing an eccentric rotation of the tool holder. The flywheel and tool holder "float" as an assembly on rubber couplings and impart to the tool components of these various motions slicing, chopping, scraping, and rubbing.Type: GrantFiled: December 22, 1975Date of Patent: October 18, 1977Inventor: Leland Z.

Patent number: 3970154Abstract: The ditcher is provided with two engines. The first engine powers the hydraulic system which rotates the digging wheel. The second engine powers the hydraulic system which actuates the wheel lifting cylinders, the conveyor system and the track driving means. The two hydraulic systems are selectively interconnected so that, in the event that the second engine fails, the first engine can be used to actuate the wheel lifting cylinders and track driving means. As a result, the ditcher's wheel can be lifted to the travelling position and the tracks driven to move the ditcher off the pipe line right-of-way and enable it to return to a base camp for repairs.Type: GrantFiled: August 23, 1974Date of Patent: July 20, 1976Assignee: Banister Pipelines, Ltd.Inventor: Fred Willie Bartels
