The level additionally includes an indicator support configured to support the orientation indicator, and a resilient member positioned between the orientation indicator and the indicator support. A compression the resilient member facilitates a calibration of the orientation indicator, while the indicator support supports the resilient member and engages opposite sides of the wall.

Abstract: The present disclosure relates to a laser level system. The laser level system includes a laser level, a quick connect tool mounting bracket, and/or other components. The laser level may be mounted to the quick connect tool mounting bracket in one or more different orientations via a quick connect adapter. The quick connect adapter may be removably coupled with the bracket and/or one or more quick connect mounts supported by one or more external surfaces a housing of the laser level. One or more laser beams generated by the laser level may be controlled via a controller to visually indicate whether the laser level is in a “manual” mode, whether the laser level is in a “self-leveling” mode, and/or whether the laser level is “out of level” while in the “self-leveling” mode. In some embodiments, the laser level system includes a self-leveling mechanism lock.

Abstract: Disclosed are various embodiments equipping a hand tool with an electronic identification device. The hand tool includes a handle having a cavity. A plug at least partially encapsulates the electronic device and inserts into the cavity in the handle. The plug may include one or more seals to prevent fluids or other debris from contacting the electronic identification device.

Abstract: The present disclosure relates to a retractable tape rule assembly locking system. The system comprises an elongated tape rule blade, a reel, a biasing spring, a stop assembly, a stop surface, a stop assembly locking device, a housing assembly, and/or other components. The stop assembly is configured to selectively engage the elongated tape rule blade to maintain the elongated tape rule blade in the extended position. The stop assembly is configured to be moveable between a default position and an open position by a user. While in the default position, the stop assembly engages the elongated tape rule blade to prevent retraction of the elongated tape rule blade. The stop surface is associated with the reel and configured to engage the stop assembly to prevent rotation of the reel to retract the elongated tape rule blade.

Abstract: A hanger configured to be mounted to a supporting surface includes a fastener receiving body configured to be positioned on the supporting surface. The hanger also includes a hook portion positioned adjacent to the fastener receiving body and configured to receive a retainable object therein. The hanger additionally includes a first datum surface associated with a first orientation direction of the fastener body. The hanger further includes a second datum surface associated with a second orientation direction of the fastener body. The relative positions of the first datum surface and the second datum surface are arranged such that when a fastener tool abuts the first datum surface and the second datum surface, a fastener applied by the fastener tool is positioned within a bounded area of the fastener receiving body.

Abstract: Embodiments generally relate to a clamp. In one embodiment, the clamp includes a bar, and a first jaw, movable along the bar and positioned on a first side of the bar. The clamp also includes a second jaw positioned on the bar on a second side of the bar, opposite the first side. The clamp also includes an actuator for moving the first jaw toward the second jaw for clamping one or more workpieces, and the actuator includes one or more drive plates operatively coupled to the bar when the first jaw is in a driving mode.

Abstract: Systems and methods are described for controlling a breakaway feature in a sliding door. The sliding door can be mounted in a doorway on a door hanger. The door is typically attached at one end using a hinge mechanism and maintained in planar alignment with the doorframe by a controllable mechanism such as an electromagnetic shear lock. An activation switch, such as a push-bar switch, initiates a delayed egress sequence that disengages the shear lock by controlling an energizing current in a magnet. When the shear lock is disengaged, the door can swing on the hinged mechanism. The delayed egress sequence can include one or more delays prior to disengaging the shear lock. Override signals can inhibit or force disengagement of the shear lock.

Abstract: A tool includes a first bit receiving socket, a second bit receiving socket, and an angled metal structure. The angled metal structure includes a first end connected with the first bit receiving socket and a second end connected with the second bit receiving socket.

Abstract: A combination manual tile cutter and a method of using the same. A manual tile cutter has an elongated cutting device mounted on a central support base and a pair of side supports pivotally connected on opposite sides of the central support base. The side supports are configured for pivotal movement between a first, open position to provide a generally planar support surface to support a work piece and a second, closed position disposed upwardly from the support base and configured to generally enclose the manual tile cutter in a polygonal (e.g., triangular) configuration. In the closed position, mutually adjacent portions of the side supports are configured to provide a hand grip to facilitate carrying of the manual tile cutter.

Abstract: A utility knife blade includes a portion made of a first material; and an elongated portion made of a second material, the second material being harder than the first material and coated on the first material by melting a powder of the second material on the first material, the elongated portion forming the tip of the blade, wherein the second material includes tungsten carbide particles embedded in a soft binder, and wherein the size of at least 90% of the tungsten carbide particles is lower than about 5 micrometers.

Abstract: A power tool includes a fluidically-driven prime mover controlled by a multi-stage, throttle-actuated dual-ported mechanism disposed in the power tool. When the first stage is actuated, pressurized fluid is admitted into the prime mover via a first delivery path in fluid communication with one of the ports. When the second stage is actuated, pressurized fluid is also admitted into the prime mover via a second delivery path in fluid communication with the other port to augment the volume of pressurized fluid admitted into the prime mover via the first delivery path. In one embodiment of the present invention, the prime mover includes a dual-chamber air motor. Upon detecting an imminent stall condition, an operator can axially advance a trigger stem to admit a boost of pressurized air into the motor via the second delivery path.

Abstract: A utility knife includes a handle, a blade holder assembly, and a clamp assembly. The blade holder assembly is constructed and arranged to hold a blade at a position of use at one end of the handle. The clamp assembly is constructed and arranged to move between a clamp position wherein the clamp assembly applies a clamp force to side surfaces the blade and a release position wherein the clamp assembly releases the clamping force.

Abstract: A tape rule includes a housing comprising a first material, a reel rotatable within the housing, an axle extending within the housing about which the reel is mounted, a measuring tape wound on the reel, and a reinforcement region comprising a portion of the housing.
