| 20120068525 | CONCRETE SAW HAVING MULTIPLE MOTORS - A device comprises an implement configured to be driven and a first motor and a second motor. Each motor includes a rotational output shaft and a transmission assembly connected to the output shaft. The output shafts of the first and second motors are coupled together by the transmission assemblies such that the output shafts turn at the same rate. The first and second motors contribute equally to the driving of the implement. | 03-22-2012 |
| 20110278907 | Concrete Profiler With Vacuum System - A concrete or asphalt profiling apparatus which operates without the use of a wetting agent includes a housing that encloses a plurality of diamond-tipped blades mounted to an arbor and adapted for high-speed rotation, and a suction device in communication with an area enclosed by the housing and configured to generate a suction force so to remove non-wetted dust generated during a profiling operation. During the profiling operation, a mixture of non-wetted dust and air can be drawn from the housing through a conduit and into a container by means of the suction device. An internally supported filter membrane extending into the container separates the concrete dust from the air in the mixture such that a portion of the concrete dust falls into a lower chamber and a portion of the concrete dust cakes on the filter membrane. The apparatus further includes a compressed air port that is adapted to selectively expel compressed air toward the filter membrane to dislodge concrete dust caked thereon. | 11-17-2011 |
| 20100251871 | Lockable Hinge For A Saw Blade Guard - A lockable hinge assembly for a blade guard includes a first hinge member secured to a first blade guard portion and a second hinge member secured to a second blade guard portion and rotatably secured to the first hinge member. A lock mechanism is provided so as to lock the second hinge member in a predetermined rotational orientation relative to the first hinge member. As such, the second hinge member and second blade guard portion can be locked in a predetermined position relative to the first hinge member and first blade guard portion, respectively. | 10-07-2010 |
| 20100043767 | Concrete Saw - A concrete saw having a geared assembly for rotating a cutting blade is described. The saw utilizes a longitudinally oriented engine for rotating the blade. Various additional features and improvements are described including a particular belt tensioner assembly, an indicator and control system for cutting blade depth, a handle adjustment and locking system, and provisions for control of blade water are described. | 02-25-2010 |
| 20100018515 | Green Concrete Saw - A green concrete saw that allows for precise adjustment of a height of a circular saw blade is provided. The saw provides for the circular saw blade to be secured to a front end of a mainframe mounted on an undercarriage. A major height adjustment is performed by adjusting the height of the mainframe relative to the undercarriage. Further, the undercarriage supports wheels for the saw, and a fine height adjustment is performed by adjusting the height of a front end of the undercarriage relative to the ground through the use of an eccentric front axle. | 01-28-2010 |
| 20090183722 | Mobile Road Or Floor Saw - A floor or road saw ( | 07-23-2009 |
| 20090044983 | Portable Concrete Boring Machine - A portable boring machine for cutting holes in a cutting surface is provided. The portable boring machine includes a vacuum system to secure a front end of the portable boring machine to a cutting surface, a hydraulic boring sub-assembly, which includes a hole saw to cut holes in the cutting surface, a water cooling/lubrication system to provide cooling and/or lubrication to the hole saw during the cutting process, and a control system to control the operation of the portable boring machine. The portable boring machine also includes multiple power-driven wheels. The wheels are attached to a bottom portion of a frame and are powered by an engine, which is mounted within the frame. | 02-19-2009 |
| 20080289470 | Bolt Lock For Saw Blades - A bolt lock is described for attachment to a blade collar of a concrete saw. The bolt lock stabilizes the position of a blade collar mounting bolt thereby preventing the bolt from loosening, which could otherwise result in the blade disengaging from the concrete saw. | 11-27-2008 |
| 20080252133 | Handle Assembly For A Concrete Saw - An adjustable handle assembly for a road surface cutting saw is provided that includes a back plate attached to the saw housing, an outer gear attached to the back plate, a bracket assembly including an inner gear, a tubular member slidably attached to the bracket assembly, and an adjustment lever having a threaded engagement end. The adjustment lever secures the bracket assembly to the saw such that the inner gear engages the outer gear. When the adjustment lever is loosened a bias spring biases the bracket assembly away from the saw such that the inner gear disengages from the outer gear to thereby allow rotation of the handle assembly to a desired operating position. | 10-16-2008 |
