Additional nozzle structures may be included. Methods and apparatus for making and using tools including concrete cutting blades having improved damping characteristics may include inserts, plugs and other structures, including those made from materials softer or more ductile than the tool material. | 04-16-2015 |
20100139230 | POSITIVE GRASS COLLECTOR ATTACHMENT POSITIONING - A grass mower for cutting grass and collecting cut grass includes a main body, two handle brackets, a handle, a collector element, and two collector brackets. The main body is for cutting grass. The two handle brackets are oppositely mounted on lateral sides of the main body. The handle is coupled to the two handle brackets. The collector element is for collecting the cut grass. The collector element is defined by a frame, and the frame includes at least two limb elements located on substantially opposite sides of the collector element. The two collector brackets are respectively mounted to the two handle brackets and are configured to respectively accommodate the limb elements, wherein the collector element is mounted on the mower free from the handle. | 06-10-2010 |
20100102525 | WHEEL HEIGHT ADJUSTER FOR WALK-BEHIND MOWER - A mower is provided that includes a height-adjuster assembly that adjustably connects the ground engaging wheel to the housing of the mower at an adjustable height from the ground. The height-adjuster assembly includes a bracket fixed to the housing, an arm, a sleeve, a wheel mount, a pin, and a handle. The arm is rotatably mounted relative to the housing and the bracket about a pivot point. The sleeve is fixed to the arm for rotation with the arm relative to the housing and the bracket about the pivot point. A handle overlays the pin and the sleeve. The handle is configured to be grasped by a user for movement along a first direction to move the pin from a first position into a second position. Upon reaching the second position, the handle and the sleeve can be rotated to rotate the ground engaging wheel relative to the housing. | 04-29-2010 |
20090127799 | SEAL STRUCTURE FOR INTERNAL COMBUSTION ENGINE - A seal structure is provided for an internal combustion engine. The seal structure can include a main seal link, at least one fastener seal connected to the main seal link and adapted to surround at least a portion of a crankcase fastener hole, and an enlarged bearing seal operatively connected to the fastener seal and adapted to be in sealing abutment with at least a portion of an outer race of a bearing. The engine can include a crankcase formed of a first section and a second section retained together with the seal structure located therebetween for providing a seal for the crankcase. | 05-21-2009 |
20080295279 | TUBE COUPLER - A powered blower/vacuum unit includes a base portion having a housing and a power air-moving device within the base portion. A tube is provided that is formed by a first manufacturing operation, such as a blow molding process. The tube extends a relatively large distance away from the housing and air flows through the tube along a relatively large distance. A coupler is also included for coupling the tube to the housing. The coupler is separately formed by a second, different manufacturing operation, such as an injection molding process. The coupler includes a plurality of one-way snap-in features configured to engage a plurality of receiver features located on the tube to non-removably attach the coupler to the tube. The housing can also include at least one male component and the coupler can include at least one complementary female component for securing the coupler to the housing. | 12-04-2008 |
20080295274 | ACCORDION VACUUM TUBE RELIEF - A powered blower/vacuum unit includes a base portion having a housing and a power air-moving device for creating an air stream. A generally rigid, elongate tube is adapted to permit at least the air stream to flow through the tube. The tube includes a fluid inlet disposed at a first end, a fluid outlet disposed at a second end, and at least one accordion relief structure disposed generally between the first and second ends and adapted to act as a resilient shock absorber. In one example, the accordion relief structure includes at least one internal rib and at least one intermediate flexible section located adjacent to each internal rib. In another example, a coupler is adapted to be removably attached to the housing and non-removably attached to the tube. In another example, a portion of the accordion relief structure is adapted to act as a positive stop for the coupler. | 12-04-2008 |
20080292455 | CENTRIFUGAL AIR BLOWER - A centrifugal blower includes a main scroll portion and a scroll opening through which air is discharged. A transitional portion conducts air discharged through the scroll opening away from the blower. The transitional portion includes an internal passageway that provides for the smooth passage of air essentially without causing any abrupt changes in the direction of the flow of the air through the passageway. An impeller assembly can be mounted within the main scroll portion for rotation so as to circulate the air in a spiral path within the main scroll portion and force the air through the scroll opening and the passageway in the transitional portion. The impeller assembly can have a platen that has a perimeter and a plurality of impeller blades mounted at the platen for rotation with the platen. Each impeller blade can have a distal end that extends beyond the perimeter of the platen. | 11-27-2008 |
20080276416 | TUBE BARRIER - A powered unit for performing blower operations or vacuuming operations is provided. The powered unit includes a blower tube, a barrier for preventing unintentional contact with moving parts in the powered unit, and a retention feature. The retention feature is located within the blower tube and the retention feature is configured for securing the barrier within the blower tube. The retention feature is included of an annular groove in the blower tube. The barrier is secured in the blower tube by a snap engagement with the retention feature. The barrier can also be deformed as it is inserted into the blower tube. The barrier then returns to its non-deformed shape when the barrier is secured in the retention feature in the blower tube. | 11-13-2008 |
20080196376 | SEPARATOR PLATE FOR POWER TOOL - A gearbox for a handheld power tool is provided, including a housing, a main gear disposed within the housing and including a plurality of cams attached thereto. A drive gear is engaged with the main gear for driving the main gear. The gearbox also includes a plurality of cutting members configured to engage the plurality of cams. Rotation of the main gear causes rotation of the cams to thereby cause the cutting members to move in a reciprocal manner. The gearbox also includes a separator plate attached to the housing. A portion of the separator plate is disposed between the plurality of cutting members to inhibit contact between the cutting members. In one example, the separator plate includes a leg section configured to be secured to a portion of the power tool. | 08-21-2008 |
20080196375 | LUBRICATION RETENTION APPARATUS FOR POWER TOOL - A gearbox is provided for a handheld power tool. The gearbox includes a housing including a recess having a wall section, a main gear disposed within the recess and including a plurality of gear teeth, and a drive gear engaged with the main gear for driving the main gear. The gearbox also includes means for retaining lubricant within the housing for improved retention of the lubricant on the main gear. The means for retaining is configured to create a localized pressure reduction within the housing during operation of the power tool. In one example, a portion of the wall section curves towards the main gear, and a localized pressure reduction is formed proximate the minimum distance between the curving wall section and the main gear during operation of the power tool. | 08-21-2008 |
