摘要： A blade positioner for a scroll saw is disclosed which permits adjustment of the saw blade relative to the pivoting beams or arms of the scroll saw so that the plane movement of the blade is coincident with the blade direction, particularly in the event that the ends of the arms are somewhat misaligned with respect to the plane of travel of the arms due to inaccuracies of the arm pivot bearing locations. Also disclosed is an anti-rattle spring interposed between the work table and work table support so as to minimize rattle of the work table relative to the support in all directions.

摘要： An arc welder has a transformer comprising a pair of flat aligned primary coils of aluminum strip wound on opposite parallel legs of a rectangular open frame core and a pair of aligned secondary coils of the same strip material wound on the same opposite parallel core legs in lateral spaced relationship with the primary coils, a flexible strip encircles each pair of aligned coils tightly banding them against lateral distortion, a flux shunting core encapsulated in molded plastic material is slidably movable through the core between the pairs of aligned coils, and mechanism for slidably moving and locking the shunting core in adjusted positions is operated by a single handle. One secondary coil of the pair comprises two windings, one wound over the other to provide two output ranges. In a modification, the addition of an outboard choke coil of round wire provides a third output range.

摘要： A compound miter saw with an adjustable/bypassable bevel stop is disclosed. The compound miter saw includes a turntable rotatably mounted on a supporting frame. A power driven saw blade is pivotally mounted to the turntable and moves along a predetermined path from an upper raised to a lower operational position that includes a saw blade slot in the turntable. A bevel adjusting features selectively rotates the power driven saw blade relative to the turntable. The adjustable/bypassable bevel stop includes predetermined bevel stop settings at set angles, for example, such as 0.degree. and 45.degree., as well as an over-riding feature when angles either less than or greater than the predetermined bevel stop settings are desired. The over-riding feature does not require re-adjustment of the predetermined bevel stop settings.

摘要： An improved compound miter saw is disclosed as having a selectively rotatable turntable mounted on a supporting frame and a power driven saw blade pivotally mounted on the turntable between a lowered full cut position and a raised full retract position. The turntable is provided with a saw blade slot for receiving the power driven saw blade when lowered to its full cut position. A work supporting fence is mounted on the supporting frame and turntable and includes a pair of work engaging surfaces longitudinally aligned across the saw blade slot. The work supporting fence is constructed to provide simultaneous longitudinal and transverse movement relative to the power driven saw blade so as to maintain the work supporting fence in a predetermined relative position to the power driven saw blade as the turntable and included power driven saw blade are selectively rotated on the supporting frame to various desired miter positions. The compound miter saw is further constructed to provide selective releasable engagement of the turntable and included power driven saw blade with respect to the supporting frame at various pre-selected miter positions of the power driven saw blade relative to the work supporting fence. For this purpose, a leaf spring with self-locating ball detent mechanism is employed between the turntable and the supporting frame for selective releasable interengagement therebetween.
