Claims
- 1. A workpiece supporting apparatus mountable upon the work surface of a power tool for translating a workpiece past the cutting member of the power tool to produce a straight precision cut in the workpiece, said apparatus comprising in combination:
- (a) an elongated keying member having an upper surface and a lower surface;
- (b) vertical slot means disposed in said keying member and extending intermediate the upper and lower surfaces thereof, said slot means including a laterally expanded portion having sidewalls and a shoulder;
- (c) first and second workpiece engaging means oriented upon said keying member in opposed relationship to one another for engaging opposed end surfaces of the workpiece, each of said first and second workpiece engaging means comprising:
- i. means for retaining an end surface of the workpiece;
- ii. a body for supporting said retaining means;
- iii. post means extending upwardly through said slot means for securing said body to said keying member, said post means being slidable along said slot means to accommodate different length workpieces and including head means for engaging said side walls to prevent rotation of said post means and for engaging said shoulder to limit upward travel of said post means; and
- iv. means for securing said body upon said post means and frictionally locking said head against said shoulder; and
- (d) means for slidably maintaining said keying member in parallel relationship to the cutting member, said maintaining means including a guide for receiving said keying member and means for fixedly appending said maintaining means to the work surface;
- whereby, said maintaining means guides the keying member supported workpiece past the cutting member.
- 2. A workpiece supporting apparatus mountable upon the work surface of a power tool for translating a workpiece past a cutting member of the power tool to produce a straight precision cut in the workpiece, said apparatus comprising in combination:
- (a) slotted elongated keying member for supporting the workpiece;
- (b) first and second workpiece engaging means attachable to and oriented upon said keying member in opposed relationship to one another for engaging opposed end surfaces of the workpiece, each of said workpiece engaging means comprising:
- i. means for penetratingly retaining an end surface of the workpiece at two points;
- ii. a body for supporting said retaining means;
- iii. post means slidable along a slot within said keying member of said keying means for supporting said body; and
- iv. means for securing said body to said post means and positionally locking said post means to a slot; and
- (c) means for slidably maintaining said keying member in parallel relationship to the cutting member, said maintaining means including a guide for receiving said keying member and means for fixedly appending said maintaining means to the work surface;
- whereby, said maintaining means guides the keying member supported workpiece past the cutting member.
- 3. A workpiece supporting apparatus mountable upon the work surface of a power tool for translating a workpiece past a cutting member of the power tool to produce a straight precision cut in the workpiece, said apparatus comprising in combination:
- (a) an elongated keying member for supporting the workpiece;
- (b) first and second means for rigidly attaching opposed end surfaces of the workpiece to said keying member, said first and second means being positionable along said keying member in conformance with the workpiece, each of said first and second means comprising:
- i. a body, said body including laterally extending members and spindles supported upon said laterally extending members for engaging the end surface of the workpiece;
- ii. post means for supporting said body; and
- iii. means for securing said body to said post means and positionally locking said post means with respect to said keying member;
- (c) means for slidably maintaining said keying member in parallel relationship to the cutting member, said maintaining means including a guide for receiving said keying member and means for fixedly appending said maintaining means to the work surface;
- whereby, said maintaining means guides the keying member supported workpiece past the cutting member.
- 4. The workpiece as set forth in claim 3 wherein said appending means comprises clamp means for clamping said keying member to the work surface.
- 5. The workpiece as set forth in claim 4 wherein said clamp means comprises a pair of clamps disposed at each end of said maintaining means.
- 6. The workpiece as set forth in claim 3 wherein said maintaining means comprises means for bolting said keying member to the work surface.
- 7. The workpiece as set forth in claim 3 wherein said guide comprises a groove recessed to fully receive said keying member and said maintaining means includes planar surfaces extending laterally from the top of said groove for supporting the workpiece secured by said keying member.
