Abstract: A book marker insertion apparatus includes a cartridge assembly, a separator assembly, a gripper assembly, an elevator assembly and a page spreader assembly. The cartridge assembly holds a roll of marker material including a plurality of markers on a backing sheet and advances the material to the separator assembly. The separator assembly includes jaws and a peel bar for removing the endmost marker from the backing sheet. The gripper assembly includes rotatable arms which grip the separated end marker and position the separated end marker for insertion into the book. The elevator raises and lowers the gripper assembly from the position for gripping the separated end marker to the position for inserting into the book. The page spreader assembly includes a V-arm with a slot formed therein-for receiving the gripper arms and the separated end marker.

Abstract: A personal binding machine for assembling a preformed coil into a stack of prepunched sheets which includes a loading tube assembly that properly orients the coil to be driven into the stack of sheets, a drive assembly which drives the coil into the stack of sheets, and crimping assemblies for crimping the ends of the coil once inserted into the sheets. The drive assembly includes a three surface contact system having a coil guide substantially adjacent the edge of the stack of sheets, a drive roller and an idler roller. While the coil guide is stationary within the housing, the location of the drive and idler rollers may be adjusted via a camming system to accommodate various coil sizes. The crimping assemblies include a cradle and blade mechanism wherein the blade presses an end of the coil into a cradle to bend or crimp the end. The drive roller may alternately be directly accessed to manually drive the coil through a stack of sheets.

Abstract: A power tool with a two-part housing has a drive motor with a pinion gear on the motor shaft. A plastic cylindrical ring gear is fixed to the motor in coaxial surrounding relationship with the pinion gear and has attachment lugs which fit between the two parts of the tool housing and are fixedly secured to each. A plastic gear carrier frame is insert molded on a splined end of a metal output shaft and is receivable within the ring gear and has radial slots for respectively receiving pins which respectively rotatably mount three planet gears in meshing engagement with the pinion gear and the ring gear. The carrier frame has a hollow stub shaft portion which receives the pinion gear therethrough, the stub shaft portion having an elastomeric O-ring seated in a circumferential groove therein for press-fitting a ball bearing thereon, the ball bearing being in turn press-fitted in a seat in the ring gear to support the planet gear assembly.

Abstract: A cordless electric device has a main body portion extending along an axis and a handle portion extending at an obtuse angle with respect to the axis, the handle portion receiving therein along a second axis a battery pack. The device has a two-part housing, with the parts respectively defining the front and rear of the body and handle portions.
