Abstract
A blade holder and adapter for a scroll saw includes a slider within a slot in a scroll saw arm, with a retainer on the slider for receiving a scroll saw blade holder. An adjuster on the slider allows the slider to move within the slot and may be tightened to retain the slider in a fixed position. Moving the slider within the slot changes the angle of the blade relative to the table of the scroll saw.
Claims11
A blade holder adapter for a scroll saw, said saw having an upper arm and a lower arm, at least one of said arms comprising a slot for receiving said adapter, the other arm holding a first end of a blade in a fixed position, and a table for receiving a work piece to be cut, said adapter comprising:
- a slider adapted to be received in said slot, said slider having an aperture, wherein said slider comprises a main body and first and second elongated tabs extending rearwardly from said main body, wherein said first and second elongated tabs are substantially parallel to each other such that a gap is defined between said tabs;
- a retainer on said slider for receiving a blade holder, said blade holder adapted to secure a second end of said blade such that said blade is held at an angle relative to said table;
- an adjuster received in said aperture of said slider and engageable with said slotted arm to move said slider in said slot and retain said slider in a fixed position;
- whereby when said adjuster moves said slider, the angle of said blade relative to said work piece located on said table is changed.
A blade holder for a scroll saw, said saw having an upper arm and a lower arm, each of said arms having a blade holder adapter for receiving said blade holder, and a table for receiving a work piece to be cut, said holder comprising:
- a first piece having a concave top side,
- a second piece having a concave top side, a front side and a back side, a clamping aperture extending from said front side to said back side, a blade stop adjacent said clamping aperture extending outwardly from said front side, and an engaging projection extending outwardly from said blade stop,
- a clamping block adapted to be received within said clamping aperture, said clamping block being inserted in said clamping aperture adjacent said front side of said second piece,
- a clamping shaft adapted to be received in said clamping aperture, said clamping shaft received within said clamping aperture,
- wherein said first piece is removably coupled to said second piece to present a concave blade receptacle for receiving said blade, and wherein rotating said clamping shaft causes movement of said clamping block within said clamping aperture to engage and hold said blade.
