20140263535 | DIRECT CURRENT FASTENING DEVICE AND RELATED CONTROL METHODS - A direct current fastening device and related control methods. The fastening device is powered by a direct current power source and includes a variety of safety and control features that allow the fastening device to be safety operated without, for example, a mechanical safety linkage or assembly between a trigger and a fastener firing portion (e.g., a nose switch) that prohibits the operation of the fastening device. Rather, the fastening device described herein employs a controller, a variety of switches, and monitoring techniques to ensure the safe and reliable operation of the fastening device. The configuration of the controller, for example, replaces the mechanical linkages and assemblies between the trigger and the fastener firing portion (e.g., a nose switch) that are ubiquitous safety features for such fastening devices. | 09-18-2014 |
20140261367 | PORTABLE TILE SAW - A tile saw for cutting a workpiece includes a frame having a guide that extends from a first end to a second end.

A saw is coupled to the frame and is operable to rotate a cutting blade about an axis and a table is operable to support the workpiece. A pan is positioned to support the frame and contain a quantity of coolant. A fourth engagement member is coupled to the third engagement member and a first latch is selectively coupled to the first engagement member. A second latch is selectively coupled to the second engagement member. The first and second latch and the fourth engagement member cooperate to restrict movement of the frame with respect to the pan. | 09-18-2014 |
20140259704 | ACCESSORY FOR A RECIPROCATING SAW - An accessory for a reciprocating power tool includes an elongated post having a base member disposed at a distal end thereof. The base member includes an aperture. The accessory includes first and second members coupled on opposite sides of the base portion. Each of the first and second side members includes a surface having a toothed portion and a non-toothed portion. | 09-18-2014 |
20140166327 | MULTI-FUNCTION TOOL SYSTEM - A power tool head is removably connectable to a power tool handle. The power tool head has an output for performing an operation on a work piece, and a housing having an inner surface defining a main cavity for receiving an interface of the power tool handle. The housing has an outer surface generally opposite the inner surface. The power tool head also has a first opening for selectively receiving a drive shaft for transferring rotation of the drive shaft to the output, the opening defining a central axis. The power tool head also has a pin extending substantially parallel to the central axis for depressing a trigger lock button, and a second opening extending from the inner surface to the outer surface in a direction generally radial with respect to the central axis for receiving a release member. | 06-19-2014 |
20140158391 | HAND HELD POWER TOOL WITH LOCKING ROTATABLE HANDLE - In an angle-grinder with a rotating handle and a latch for fixing the handle in two different rotational positions, an interlock mechanism is provided for greater security against unwanted rotation of the handle when the tool is being used. The interlock mechanism is moved to a locking position by depressing the trigger to start the motor, and thus provides a safety lock backing up the latch, in case the latch is accidentally released during use. In its unlocking position the interlock mechanism may prevent actuation of the trigger when the handle is not properly aligned in one of its operating positions. | 06-12-2014 |
