摘要:
A two-stroke internal combustion engine (1) is provided with a fuel injector (24). The two-stroke internal combustion engine may have at least one transfer passage (30), an air channel (21), and a fuel injector (24). The transfer passage (30) is between a crankcase (3) and a combustion chamber (14) of the engine. The air channel (21) is in gaseous communication with a top portion of the transfer channel. The fuel injector (24) is in gaseous communication with the air channel (21) and injects fuel into the air channel (21). The two-stroke engine may be used on hand-held, lawn and garden equipment.

A portably log splitter is provided. The log splitter comprises a base (18) having a pair of one-piece side members (26,28), and a support member (16) to which the one-piece side members are attached. The support member and the one-piece side members form a seat that is adapted to receive a log. The log splitter also includes a splitting wedge (14) that is attached to the support member and a contact member (54) that is configured to translate in a reciprocal manner adjacent to the support member in order to move the log. The log splitter also includes a control assembly operated by a switch to actuate the contact member in the reciprocal manner.

A plug identity system includes a plug with a light source and an information indicator. The light source may be clear, white, or emit a color in the visible spectrum that would indicate to a user information about the device the plug is attached to. The information indicator may include translucent, transparent and opaque areas. The information indicator may be of a color to provide indicative information about the device the plug is attached to. The translucent, transparent and opaque areas may be configured to represent icons, logos, initials, names and the like to provide indicative information about the device the plug is attached to.

A wet/dry vacuum is disclosed. The wet/dry vacuum preferably includes a base (10), a handle (12) coupled with the base, a lid (14) coupled with the handle, and a container (16) that is removable from the base (10). In operation, the container is placed on the base. As the handle is rotated towards the rear of the base, the handle secures the container to the base by lowering the lid onto the container.

A surface planer (10) for planing a wooden board (12) comprising a motor (24) having a rotationally driven motor output member turning at a first rotational speed; a rotary cutter head (26) operatively connected to and rotationally driven by the motor output member; a pair of feed rollers (28,30) longitudinally spaced about the rotary cutter head; a frame (14) including at least two laterally spaced apart columns (18) on opposite lateral sides of the board to be planed which is adjustably positionable by the operator at a selected distance from the cutter head in order to achieve a selected board thickness; and a multi-stage transmission having an input connected to the motor (24) and an output drivably connected to at least one of the feed rollers, the multi-stage transmission including a dual speed stage provided with an operator actuated speed selected element (70) which when shifted by the operator, changes the final drive ratio and the resulting speed that the feed rollers move the wooden board relative to the cutter head.
摘要:
The present invention discloses a battery pack (20) having an elastic bumper (58) mounted externally to a plastic housing (44) of the battery pack. The plastic housing includes a floor (46), a circumferential wall (48) expanding upward from an outer peripheral edge of the floor and a cap (50). The floor, wall, and cap collectively define an enclosed internal cavity (52) wherein a plurality of battery cells (54) are mounted for providing power to the power tool (22). The elastic bumper serves as a cushion in the event of an impact load exerted on the battery pack or exerted on the battery pack and the associated power tool, if the battery pack or the assembled power tool and battery pack are dropped in an orientation in which the battery pack strikes a hard surface.
