Abstract: A pin with threads that extend along a portion of a stem of the pin interact with framing members as the pin pierces and is axially driven through the framing members. The interaction of the threads with the framing members cause the pin to rotate as the threads pass through the framing members and fastens the framing members together.

Abstract: A power tool is provided with a hanger having multiple discrete width positions to engage materials of different thicknesses. The power cord is installed in the tool housing with an extra length of cable between the cord clamp and the portion of the tool housing that secures the cord protector. A crimp-on device is installed on the power cord cable next to the cord protector. When the cord is subjected to jerking, the cable moves axially relative to the cord protector. As the cable moves, the crimp-on device compresses the extended end of the cord protector absorbing energy and reducing the forces transmitted to the cord set conductors. A rip guide includes a long guide edge and two attachment points to the shoe/base of the saw. The rip guide is attached to the base/shoe via a pair of L-shaped openings that accept L-shaped support arms of the rip guide.

Abstract: A clamping assembly is provided for retaining an accessory on the spindle of a power tool. The clamp assembly preferably includes a planetary gear system for transmitting torque applied to the clamp assembly to the accessory, wherein the planetary gear system multiplies the torque transmitted to the accessory so that the torque transmitted to the accessory is greater than the torque applied to the clamp assembly. An extendable lever or a handle may also be included for increasing the amount of torque applied to the clamp assembly by the user.

Abstract: A pin with threads that extend along a portion of a stem of the pin interact with framing members as the pin is driven through the framing members.

Abstract: A reciprocating saw 11 comprises an output shaft 21 mounted for reciprocal motion in a housing 13. A counterweight 27 is mounted in the housing for reciprocal movement relative to the output shaft. A first drive 37 is connected between a motor and the output shaft for reciprocally driving the output shaft. A second drive 39 is connected between the motor 19 and the counterweight for reciprocally driving the counterweight. The second drive 39 preferably comprises a pivot arm 41 pivotally mounted about an axis transverse to the output shaft for receiving at a first location a reciprocating input in a first direction 40 and for producing at a second location a reciprocating output in a second direction 42 different from the first direction. The first and second drives provide a compact, low vibration, relatively simple, counterbalanced drive train for the saw.

Abstract: The present invention provides a circular saw including a housing, a motor within the housing, a circular saw blade rotatably driven by the motor, a base and a bevel angle adjustment mechanism. The bevel angle adjustment mechanism pivotally interconnects the base to the housing such that the circular saw blade is adjustable relative to the base through a range of bevel angles. The bevel angle adjustment mechanism includes a first member carrying a detent and a second member defining a cooperating recess. The detent and the cooperating recess positively define at least one predetermined bevel angle setting.

Abstract: A power tool includes a motor having a first shaft, a transmission mechanism operatively connected to the first shaft, a second shaft operatively connected to the transmission mechanism, a housing enclosing the transmission mechanism and adapted to contain a quantity of lubricating grease, and an auger rotatably disposed within the housing on at least one of the first and second shafts for circulating the grease within the housing. A blade may be operatively connected to the second shaft. The transmission mechanism includes a first gear operatively connected to the first shaft, and a second gear operatively connected to the second shaft, where the second gear operatively meshes with the first gear. It may be advantageous to dispose the first and second gears in such a manner so that distance between the blade and the second gear is larger than the distance between the blade and the first gear.

Abstract: A hand-held orbital polisher includes a housing, an electric motor and hand-operated motor control device mounted in the housing, and a pair of handles closely coupled to a housing to position an operator's thumbs adjacent the control device. The control device includes an electrical switch having a slidable actuator and a pair of thumb-actuated levers to selectively move the actuator into either of two on positions or into an off position. The levers are pivotably mounted to the housing, have a collar drivingly connected to the actuator, and a thumb pad at one end. The pivots can be defined at the other end of the levers and the collar at the center, or at the center of the lever and the collar at the other end of the lever. One or both of the user's thumbs can be used to apply a force with a force on one lever being transmitted simultaneously to the actuator and thereby against the other beam whereby to force the two levers in one or the other position, the operator's hand never having to leave the handles.

Abstract: Tickets with customer markable areas are insertable into an input slot facing the agent side of the processor, an input slot facing the customer side of the processor, or by either the agent or the customer into an input slot located on the top of the processor. The slots feed different points along an arcuate channel. The end of the channel is located at the beginning of a straight line transport path passing through a ticket reader and a ticket printer to an output slot facing the agent side of the processor. A single drive motor, actuated by a ticket sensor at the end of the channel, provides power to all of the drive rollers. A lock-out mechanism located in the channel prevents tickets from being inserted from the agent side or the top surface if a ticket has been received from the customer side, and prevents tickets from being inserted from the customer side if a ticket has been received from the agent side.

Abstract: A print head for use in a dot matrix printer or the like which comprises a plurality of non-magnetic frames which carry aligned magnets, the frames being arranged in a stack with spaces formed by projecting parts on the frames between the magnets carried thereby, the printer hammers being movably located in those spaces and extending out between the frames to the printing station. A head comprising a desired number of hammers is built up by stacking the appropriate numbers of alternating frames and hammers.

Abstract: The stack of sheets is urged towards a rotatable removal roller located at the top of the magazine. The roller is mounted on a frame which is pivoted relative to the magazine to provide access to the stack for reloading. Pivoting of the frame automatically actuates a spring-loaded rachet-type mechanism which prevents movement of the stack towards the open top end of the magazine, without interfering with the placement of additional sheets onto the stack.
