Abstract

A vise for clamping two works comprising a vise body having a groove of T-shaped section and first and second reference surfaces perpendicular to the groove; a pair of movable members fitted in said T-shaped groove between said first and second reference surfaces, having clamping surfaces opposed to said reference surfaces, respectively, and provided at the rear sides opposite to said clamping surfaces with inclined surfaces inclined to converge toward the T-shaped groove; a wedge fitted between said inclined surfaces; a block slidably and disengageably fitted in the T-shaped groove between said movable members; and a bolt connecting said wedge and the block for forcing the wedge toward the block. The second reference surface is disposed on a supporting member which carries an inclined third reference surface. By removing a movable member and reversing the supporting member, the third reference surface opposes the first reference surface for clamping a single work therebetween.

Claims

1. A vise which is transformable for selectively clamping one or more works, comprising:

a vise body having a groove of generally T-shaped cross-section extending longitudinally, said groove extending all the way to a first longitudinal end of said body to form a groove open end,

a first upstanding reference surface carried by said body adjacent a second longitudinal end of said body opposite said first longitudinal end, said first reference surface oriented perpendicularly relative to a longitudinal axis of said groove,

a supporting member slidably mounted in said groove adjacent said groove open end and including second and third upstanding reference surfaces spaced apart longitudinally, said second reference surface oriented parallel to said first reference surface, and said third reference surface being inclined so as to extend at an acute angle toward said groove in diverging relationship to said second reference surface,

fastener means for securing said supporting member against sliding movement in said vise body in longitudinally spaced relationship relative to said first reference surface to define a works-receiving space therebetween,

first and second movable clamping members relatively slidably mountable in said groove within said worksreceiving space, each of said clamping members including a clamping surface disposed parallel to said first and second reference surfaces, and a wedge surface inclined so as to extend at an acute angle toward said groove in diverging relationship to said clamping surface, said wedge surface acute angle being the same as said third reference surface acute angle, said clamping members being positionable such that said wedge surfaces oppose one another and said clamping surfaces oppose respective ones of said first and second reference surfaces,

a wedge positionable between said opposed clamping surfaces and including a pair of inclined surfaces diverging in a direction toward said groove and oriented complementarily to said wedge surfaces,

a bolt extending through said wedge and into said vise body for moving said wedge toward said groove to urge said clamping surfaces toward the respective first and second reference surfaces for clamping first and second works therebetween,

said fastener means being releasable to permit said supporting member and one of said clamping members to be removed from said groove through said groove open end, said supporting member being re-insertable into said groove after being reversed to position said third reference surface in opposing relationship to the remaining wedge surface to enable said wedge to be positioned therebetween to urge the remaining clamping surface toward said first reference surface for clamping a single work therebetween.

2. A vise according to claim 1, wherein said first and second reference surfaces are removably mounted on said vise body and said supporting member, respectively, so as to be replaceable with reference surfaces of different shape.

3. A vise according to claim 1 including a stop member releasably securable to said vise body for closing said groove open end.
