- a plunger being slidably positioned in said bushing wherein said plunger is configured to be pushed upon by the user, said plunger extending toward said drive wheel when said plunger is urged to travel in a first direction, said plunger being biased to travel in a second direction, said plunger comprising:
- a shaft having first end and a second end and an outside surface extending between said first end of said shaft and said second end of said shaft, said shaft extending through said bushing having said outside surface slidably engaging an interior surface of said exterior wall of said bushing, said shaft being slidable in a primary direction in said bushing or a secondary direction in said bushing, said outside surface having a cut out portion extending from said second end of said shaft toward said first end of said shaft, said cut out portion having a first bounding surface lying on a plane being oriented perpendicular to said second end, said cut out portion having a second bounding surface being oriented perpendicular to said first bounding surface, said second bounding surface lying on a plane being oriented parallel to said second end;
- a knob having a front end and a back end and an exterior wall extending between said front end and said back end, said exterior wall of said knob having a receiver section and a gripping section, said receiver section having a diameter being less than a diameter of said gripping section, said knob having a shaft hole extending through said front end and said back end, said shaft extending through said shaft hole such that said knob is slidably positioned on said shaft having said back end being spaced from said primary end of said bushing, said exterior wall of said knob associated with said gripping section having a plurality of intersecting surfaces being oriented at an angle with each other such that said gripping section has a polygonal shape wherein said gripping section is configured to enhance a grip of a user when the user grips said gripping section;
- a knob set screw extending through said receiver section of said exterior wall of said knob and into said shaft hole, said knob set screw compressing against said outside surface of said shaft when said knob set screw is tightened for retaining said knob at a selected point along said shaft;
- a biasing member extending around said bushing, said biasing member extending between said lip on said sleeve and said back end of said knob, said biasing member biasing said knob to travel away from said sleeve, said biasing member being compressed when said knob is urged to travel toward said sleeve, said shaft traveling in said primary direction in said bushing when said knob is urged to travel toward said sleeve, said shaft travelling in said secondary direction in said bushing when said knob is biased to travel away from said sleeve;
- a locking collar having an outwardly facing surface extending between a forward surface and a rearward surface, said bushing extending through said locking collar having said forward surface resting against said second end of said sleeve, said forward surface of said locking collar abutting said second end of said sleeve when said biasing member biases said knob to travel away from said sleeve such that said locking collar limits a distance said shaft can travel in said secondary direction, said locking collar being positionable on said bushing such that said second end of said shaft is spaced a selected distance from said drive wheel of said bandsaw when said biasing member biases said knob to travel away from said sleeve;
- a collar set screw extending through said outwardly facing surface of said locking collar, said collar set screw compressing against said exterior wall of said bushing when said collar set screw is tightened for inhibiting said locking collar from sliding along said exterior wall of said bushing;
- and
- an annular gasket being positioned around said bushing, said annular gasket being positioned between said forward surface of said locking collar and said second end of said sleeve, said annular gasket being comprised of resiliently compressible material such that said annular gasket is compressed between said forward surface of said locking collar and said second end of said sleeve when said biasing member biases said knob to travel away from said sleeve wherein said annular gasket is configured to reduce noise produced by vibration of said bandsaw;
- a brake pad being removably attachable to said plunger, said brake pad pressing against said drive wheel when said plunger is urged to travel in said first direction having said brake pad frictionally engaging said drive wheel such that said brake pad stops rotation of said drive wheel wherein said brake pad is configured to stop rotation of said bandsaw when the user presses upon said plunger, said brake pad being spaced from said drive wheel when said plunger is biased to travel in said second direction such that said drive wheel can rotate freely, said brake pad having a forward end and a rear end and an outermost surface extending between said forward end and said rear end, said forward end having a first well extending toward said rear end, said first well having a rear bounding surface, said rear bounding surface having a second well extending toward said rear end, said second well has a first lateral bounding surface and a second lateral bounding surface, said first lateral bounding surface being oriented perpendicular to said rear bounding surface, said second lateral bounding surface being concavely arcuate with respect to said first lateral bounding surface such that said second well has a semicircular shape, said second well insertably receives said second end of said shaft having said first bounding surface of said cut out portion of said outside surface of said shaft conforming to said first lateral bounding surface of said second well such that said shaft is inhibited from rotating in said second well;
- a brake set screw extending through said outermost surface of said brake pad, said brake set screw compressing against said first bounding surface of said cut out portion of said outside surface of said shaft when said brake set screw is tightened for retaining said brake pad on said head;
- a friction pad having a coupled surface being coupled to said rear end of said brake pad having said coupled surface completely covering said rear end, an exposed surface of said friction pad pressing against a lateral surface of said drive wheel when said knob is urged toward said sleeve to produce friction between said lateral surface of said drive wheel and said exposed surface of said friction pad;
- and
- a cushion being applied to said forward end of said brake pad having said cushion extending around said first well, said cushion being comprised of a resiliently compressible material such that said cushion is compressed between said forward end of said brake pad and an inner face of said door when said biasing member biases said knob to travel away from said sleeve wherein said cushion is configured to reduce noise produced by vibration of said bandsaw.
