摘要:
A vacuum attachment assembly for a scroll saw wherein the scroll saw includes a base, a table, a table bevel lock knob, a table bevel plate, an upper arm and a lower arm-blade. The vacuum attachment includes a bracket having first and second ends. The first end of the bracket has an opening for receiving the table bevel lock knob. The second end of the bracket has an opening of predetermined size and is oriented so that the opening is located under the scroll saw table near the lower arm-blade assembly. The vacuum attachment assembly also includes an elbow that is connected to the opening of the second end of the bracket. A hose is connected to the elbow and oriented to collect and divert saw dust away from the table of the scroll saw.

A motor housing for a variable speed scroll saw or other operating tool is disclosed. The motor housing includes a motor as well as a printed circuit board mounted in the motor housing adjacent the motor. A switch is attached to the printed circuit board and extends outside of the motor housing. The switch is also attached to the motor housing. A switch lock-out is operably associated with the housing for disabling the switch until the switch lock-out is disengaged. Preferably, the switch lock-out is a releasable locking mechanism such as a padlock.

A tool assembly for a vacuum appliance, such as a wet/dry vacuum cleaner, is described, wherein the tool assembly may include a frame, a mount configured to couple the frame to the appliance, a pivot, an actuator configured to support the frame in one or more positions, and a tool coupled to the frame. The assembly may also include a biasing device between the pivot and an end of the frame, and may be disposed in one or more positions relative to a vacuum surface. Also described is a vacuum appliance system that can include a debris collector, a power head assembly, a base, and a tool assembly. Such a vacuum appliance system can also include a main wheel assembly and a plurality of optional main wheel assembly mounting locations. The system may further include a quick-release filter cage coupled to the power head assembly.

A self-aligning quick pick-off rip fence for use in a table saw is disclosed. The rip fence holds a workpiece relative to a rotatable saw blade extending through an upper surface of the table saw for longitudinal or rip cutting along the length of the workpiece. The rip fence includes a fence head slidably mounted to a front rail that is attached to the table saw. A fence channel is mounted to the fence head at a first end and extends across the upper surface of the table saw in generally parallel alignment with a plane extending through a rotatable saw blade and terminates in a second end. A self-aligning bearing is attached to the second end of the fence channel and is slidably mounted relative to a rear rail attached to the table saw. A handle assembly is mounted to the first end of the fence channel and is interconnected to the self-aligning bearing for engaging and disengaging same in locked and unlocked relationship to the rear rail. When locked to the rear rail, the self-aligning bearing causes the fence channel to be aligned in substantially squared position relative to the front rail, and when unlocked from the rear rail, enables the entire fence head and channel to be removed from the table saw. The self-aligning quick pick-off rip fence further includes both parallel and incremental adjustment structure for adjusting the fence in parallel relationship to the plane extending through the saw blade as well as precise incremental adjustment of the fence channel relative to the saw blade.

In a method and apparatus for manufacturing a flechette load, a series of operative steps are carried out to produce a matrix-supported load of flechettes held in a desired array. First, a load of flechettes are mounted by a die end cap in a desired array in which at least the trailing end portions thereof are exposed and disposed in closely spaced side-by-side relation. Next, the die end cap is assembled to a die body such that at least the exposed trailing end portions of the flechettes are placed in the mold cavity of the assembled die. A mixture of expandable thermoplastic beads and, preferably, a bond weakening agent is also placed in the mold cavity with the mixture surrounding the exposed trailing end portions of the flechettes therein. Finally, the mixture is heated so as to produce in the mold cavity directly on and about the exposed trailing end portions of the flechettes a matrix in the form of a solid foam body of a thermoplastic foam material. The desired precise location and alignment of the flechettes relative to one another is thereby fixed by the solid matrix before placing the matrix-supported flechette load as a unit into a shell.
