专利汇可以提供Clamp for precision cutting tool专利检索，专利查询，专利分析的服务。并且Apparatus for precision cutting of sheet material (e.g. nonferrous metals such as aluminum, brass, asbestos board, or the like), comprising a work-support table, displacement-sensing means mounted along two adjacent sides of said support table and a novel quick-clamping means for holding a workpiece against said table. The quick-clamping means has an elongate clamp bar along each side of the cutting tool, these elongate bars comprising biased means therealong for compensating for differences in thickness along the length of said workpiece.，下面是Clamp for precision cutting tool专利的具体信息内容。

权利要求

1. A clamp for holding a workpiece firmly against a work table and thereby to enable the precision cutting of said workpiece, said clamp comprising A. two elongate clamp members defining a slot between said clamp members said slot adapted to form a travel path for a cutting tool; B. A plurality of downwardly extending biasing means arranged along the length of each said clamp member, said biasing means adapted to provide means for biasing said clamp and said workpiece to assure clamping contact of said workpiece against said work table; C. means to raise said clamp vertically from said work table to provide a variable clearance between said table and said clamp, and D. means to maintain substantially constant clamping pressure on said clamp at variable clearances from said table.

2. cam rollers positioned for rotation in said slots of said post, said cam rollers forming means to transmit force to said post members on actuation of said lever means.

2. cam rollers positioned for rotation in said slots of said post, said cam rollers, forming means to transmit force to said post members on actuation of said lever means.

2. Apparatus as defined in claim 1 wherein said biasing means exert a minimum of 600 psig.

3. A clamping apparatus as described in claim 1 comprising additionally a saw housing comprising two moveable side shields adapted to be moved freely up and down in response to the vertical movement of said clamp.

4. A clamp as defined in claim 1 wherein said means for raising and lowering said clamp members with respect to said table are actuated by force applied proximate to each end of said clamp members, and wherein said means for raising and lowering said clamp members comprise: a. post members connected to said clamp members proximate to each end thereof, each of said post members comprising a slot therein, b. ball bushings mounted on said table and forming means to receive, for slideable vertical movement therein, each of said post members, c. means to vertically move said post members thereby, adapting said clamp members to clamp and unclamp said object and wherein, i. said means to vertically move said post comprising

5. Apparatus as defined in claim 1 wherein said biasing means comprise a series of apertures, each having a spring connected within, each spring normally protruding from its associated aperture, thereby providing a biasing means which has no substantial effect when said springs are compressed into said apertures.

6. Apparatus as defined in claim 5, wherein said biasing means exert a minimum of 600 psig.

7. A clamp as defined in claim 5 wherein said means for raising and lowering said clamp members with respect to said table are actuated by force applied proximate to each end of said clamp members, and wherein said means for raising and lowering said clamp means comprise: a. post members connected to said clamp members proximate each end thereof, each of said post members comprising a slot therein, b. ball bushings mounted on said table and forming means to receive, for slideable vertical movement therein, each of said post members, c. means to vertically move said post members thereby, adapting said clamp members to clamp and unclamp said object and wherein, i. said means to vertically move said post comprising
