Publication number: 20230064531Abstract: A concrete/cement resurfacing machine integrates a dust collection subsystem and an overlay mixing/distribution subsystem, enabling a single operator to steer the machine to a desired floor location and deposit mixed, cementitious overlay material. The combination of dust collection and overlay mixing saves considerable time and achieves improved results, eliminating the need for separate vacuum machines while reducing the risk that dust will be released as bags of dry ingredients are added to the mixing tank. A single propane engine powers a hydraulic pump, with fluid being routed to three separate hydraulic motors with associated control valves to provide for forward/reverse locomotion, bidirectional paddle mixing, and vacuum generation. The dust collection system is preferably a two-stage system including a vacuum collection tank and a HEPA filter.Type: ApplicationFiled: August 26, 2022Publication date: March 2, 2023Inventor: Donald A. Pope, Jr.

Publication number: 20230067358Abstract: A walk-behind, wet/dry grinder/polisher adapted for concrete floors does not use of pulleys, belts or chains. Maintenance is significantly enhanced, as such components are typically the first to wear out and cause replacement issues. A frame with forward and rear portions pivots about a single set of right and left wheels. A planetary grinding head, powered by a propane engine, is coupled to the forward portion of the frame. In contrast to all known designs, the engine is directly, mechanically coupled to the grinding head without the use of pulleys, belts or chains. The direct, mechanical coupling to the grinding head preferably uses a centrifugal clutch. A water tank and water feed line from the water tank to the grinding head facilitate wet floor grinding and polishing. The grinding head is also encased in a shroud coupled to a tube for dust collection associated with dry floor grinding and polishing.Type: ApplicationFiled: August 26, 2022Publication date: March 2, 2023Inventor: Donald A. Pope, JR.

Publication number: 20230032463Abstract: A walk-behind grinder/polisher receives removably attachable wet and dry debris collection modules. These modules are substantially rigidly attached to the frame of the grinder/polisher and suspended above a floor surface so as to travel with the grinder/polisher when coupled thereto. Each debris collection module removably attaches to a vacuum producer mounted on the frame of the grinder/polisher. An engine drives a first hydrostatic pump in fluid communication with a first hydraulic motor driving the grinding/polishing head in reversible fashion. The engine further drives a second hydrostatic pump in fluid communication with a second hydraulic motor driving the vacuum producer. The dust collection module has an inlet removably attachable to the dust collection port on the shroud, and an outlet coupled to a dust collection canister. The slurry collection module has an inlet removably attachable to a squeegee, and an outlet coupled to a slurry containment vessel.Type: ApplicationFiled: July 28, 2022Publication date: February 2, 2023Inventor: Donald A. Pope, Jr.

Publication number: 20230000296Abstract: A high-power slurry vacuum cart is well suited to collect and contain any slurry or wet residue produced through concrete and other surface processing operations. A multi-horsepower propane engine and propane tank are mounted on a mobile frame, along with a suction pump powered by the propane engine. A slurry containment vessel mounted on the frame has an input in communication with a squeegee and an output coupled to the suction pump. The squeegee may be adapted for floor contact to collect slurry for transfer to the slurry containment tank. The suction pump is directly coupled to the propane engine through a universal joint, thereby obviating the use of belts, chains or pulleys. The output of the pump may optionally be used as an air blower for surface drying, or the like, as well as use as an air blower to assist in emptying the slurry containment tank.Type: ApplicationFiled: May 20, 2022Publication date: January 5, 2023Inventor: Donald A. Pope, JR.

Publication number: 20220410433Abstract: A combination cart providing independent electrical power generation and dust extraction capabilities finds utility in concrete processing and other operations that create unwanted dust using hand tools for cutting, grinding, polishing, coring, drilling, sanding, and the like. A propane tank powers a propane engine, and the propane engine drives an electrical generator providing power to an electrical outlet panel mounted on the frame. The cart further includes a dust extraction and filtration system driven by an electric motor, also mounted on the frame.Type: ApplicationFiled: May 20, 2022Publication date: December 29, 2022Inventor: Donald A. Pope, JR.

Publication number: 20220403672Abstract: Lightweight, battery-operated, walk-behind joint- and crack-filling equipment has no belts or chains to wear out, and no inverters or other electrical power-conversion apparatus. A single brushless battery-operated DC motor, directly coupled to two pumps, simultaneously delivers the resin and hardener to a wand, such that a single user can push the cart and apply the mixture. The portable cart includes a frame with a handle and single set of right and left wheels accommodates two containers holding the hardening components. The containers may be pails or buckets or bag-in-box containers that may be compressed and collapsed after use to reduce waste requirements. The boxes and/or bags may also be biodegradable for a more environmentally friendly solution.Type: ApplicationFiled: March 7, 2022Publication date: December 22, 2022Inventor: Donald A. Pope, JR.

Patent number: 11389990Abstract: A concrete mixing machine for indoor preparation of fluid concrete for disposition as flooring. The concrete mixing machine includes a mixer tank capable of mixing of twenty-three bags of concrete concurrently. Mixing propellers inside of the mixer tank attach to a shaft, whereby a hydraulic propeller drive motor rotationally moves the shaft, and the mixing propellers mix the concrete. The concrete mixing machine produces a large batch of concrete, and the concrete mixing machine moves and deposits the concrete for application using a flow control mechanism with a flow control mixer attached to the mixer tank that regulates concrete flow through a valve and chute and synchronizes with a flow control drive-wheel. The concrete mixing machine is hydraulically operated and self-propelled. The concrete mixing machine does not emit gases harmful to indoor air quality and thus is environmentally friendly.Type: GrantFiled: April 13, 2020Date of Patent: July 19, 2022Inventor: Donald A.

Patent number: 7900420Abstract: A pressure joining method includes a hammer drill attachment device mountable within the chuck of a hand-held hammer drill. Using the hammer drill attachment, an operator installs flooring sheets onto a hook and loop flooring subfloor. The hammer drill attachment includes a shaft for mounting the attachment within the chuck. The hammer drill imparts vibration to the shaft when operated. An angled body member is attached to the shaft and extends downward toward a foot assembly having a foot pad means. The foot assembly vibrates when the hammer drill is actuated to cause the foot pad means to abut against the overlapping sheets of a flooring system and to press the sheets onto an underlying subfloor, thereby forming a seam between the edges of the floor sections.Type: GrantFiled: August 28, 2009Date of Patent: March 8, 2011Inventor: Donald A.
