摘要： A cutting blade (58) is secured to the lower end of a flexible drive shaft (18). Drive shaft (18) extends from the blade (58) upwardly through a tubular handle (12).The upper end of the drive shaft (18) is connected to the output of a drive motor (14). The cutting blade (58) is within a housing (10) having a bottom opening (64) and three lower side openings (72, 74, 76). A cutting blade (58) includes a pair of section vanes (104) which when the cutting blade 58) is rotating serve to pull air into the housing (10) through the lower sidewall openings (72, 74, 76). The moving air picks up the cuttings and moves them rearwardly into a cuttings bag (92) which is connected to and supported from a rear portion of the housing (10).

摘要： A grout removal tool includes an adapter having a replaceable cutting blade mounted thereon. The adapter is configured to be installed within a common reciprocating saw. The adapter has a proximal attachment end for attachment to the saw, an elongated proximal leg extending from the proximal attachment end, and an elongated distal leg extending from the proximal leg at an angle to terminate in a distal end whereupon the cutting blade is attached. When the proximal attachment end of the adapter is installed within the reciprocating saw, the cutting blade reciprocates in a parallel plane beneath the plane in which the proximal leg reciprocates. When the cutting blade is reciprocated across a grouted work surface, it results in a high rate of grout removal with low dust dispersion.

摘要： A rotary cutter for a mower is provided wherein the cord delivering operation, which is necessary when the free end of the cord is worn, is carried out only when the rotary cutter is rotated at a low speed or is stopped. The rotary cutter includes a cord for cutting grass upon rotation thereof, a reel which holds the cord and allows delivering of the cord while the reel is intermittently rotated, a cover for a case which houses the reel, and a press body which protrudes downwardly from the case and is movable in an axial direction upon pressing so as to intermittently rotate the reel. A return spring for biasing the press body in a direction to protrude the press body from the case between the reel and the press body is also provided. The press body and the case engage each other such that the press body is slidable in an axial direction while preventing relative rotation with each other. By pressing the press body against the biasing return spring, a set of protrusions formed on the press body are detachably engaged with protrusions formed on the reel so as to intermittently rotate the reel.

摘要： The present invention 10 is an improved electric knife with several enhancements which make it uniquely suited for use in its intended watery environment. In case it is accidentally dropped in the water, it has several floatation chambers 54 in the handle 24 and the end cap 52 that will keep it afloat and nearly water and damage free for a reasonably long period, certainly time enough for any reasonably serious effort at retrieval to be effective. The end cap 52 is highly buoyant, having a sealed partial vacuum chamber 54. The housing has several sealed buoyant air chambers 54 in the. rearmost area to directly offset the weight of the battery pack 36. The motor housing unit also provides buoyancy and floatation by the presence of the water-resistant seal 63 at the juncture of the knife blades 42 and the handle housing 24. The critical areas around switches 44, 50 and access openings are also watertight for operating in wet or rainy conditions. Additionally, there is a light 48 in the top front area of the handle with its nearby water-sealed 56 switch 50 for illuminating the work area when operating under night or low light conditions. The present invention comes with a carrying case 18 and many additional components: a recharging unit 34 for recharging the power pac 36, a reenergizer 38 for charging the power pac 36 and operating under AC simultaneously, a spare power pac 36, 2 different sized interchangeable blade sets 26, a blade cover 28, DC 12 volt power cord 30, AC power cord 32 and the fillet knife housing unit.

摘要： Disclosed is an automatic metal printer which prints a camera-photographed and computer-processed image on a surface of a hard material, such as a metal sheet, through a dot matrix printing type method wherein brightness of the printed image is expressed in accordance with density of dots in the dot matrix formed on the surface of the hard material. The automatic metal printer includes a platform which reciprocates forward and rearward in a lower portion of a body by a motor-operated first ball screw. A saddle is installed at a position above the platform so as to reciprocate to the left and right in the body by a motor-operated second ball screw. A dotter is vertically installed on the saddle so as to dot the upper surface of the hard material seated on the platform to print a desired image.
