Precision machine vise
First Claim
1. A vise for use with a machining table having a flat upper surface and at least one elongated T-slot in said upper surface, comprisinga first vise jaw movable within said elongated T-slot to any desired position on said table,first clamping means within said T-slot for clamping said first jaw in a first stationary position on said table,a second vise jaw,a jaw support for supporting said second vise jaw,second clamping means within said T-slot for clamping said jaw support in a second stationary position on said table spaced from said first jaw,means for mounting said second jaw on said jaw support for movement relative to said first jaw in the direction of said T-slot, said mounting means on said second jaw horizontally surrounding said jaw support said jaw support and said second jaw having opposing surfaces extending transverse to said T-slot, at least one of said opposing surfaces being in a plane inclined to said upper surface of said table,a wedge member inserted between said opposing surfaces and having opposite sides conforming in inclination to, and pressing against said opposing surfaces, andmeans for adjusting the position of said wedge member in a direction perpendicular to said upper surface of said table, thereby to adjust the position of said second jaw relative to said first jaw, wherein said second jaw is biased toward said jaw support by a biasing means acting between said second support mounting means and said jaw support in the direction of the slot.

Abstract
A vise for use with a machining table having an elongated T-slot in its upper surface includes a stationary jaw and a jaw support transversely extending over the T-slot and clamped against the table in spaced relation to one another by a clamping device centrally extending through the jaw and jaw support into the T-slot. A movable jaw is mounted on the jaw support with its gripping surface facing the gripping surface of the stationary jaw and its opposite surface inclined to the table. A wedge member having an inclined surface conforming to the inclined surface of the movable jaw is located between the movable jaw and the jaw support. Adjustment of the vertical position of the wedge member relative to the table enforces a horizontal motion of the movable jaw to grip a work piece located between the jaws. An auxiliary base member with a T-slot in its upper surface is also provided upon which the vise may be alternatively mounted for portable free-standing use.

1. A vise for use with a machining table having a flat upper surface and at least one elongated T-slot in said upper surface, comprising
a first vise jaw movable within said elongated T-slot to any desired position on said table, first clamping means within said T-slot for clamping said first jaw in a first stationary position on said table, a second vise jaw, a jaw support for supporting said second vise jaw, second clamping means within said T-slot for clamping said jaw support in a second stationary position on said table spaced from said first jaw, means for mounting said second jaw on said jaw support for movement relative to said first jaw in the direction of said T-slot, said mounting means on said second jaw horizontally surrounding said jaw support said jaw support and said second jaw having opposing surfaces extending transverse to said T-slot, at least one of said opposing surfaces being in a plane inclined to said upper surface of said table, a wedge member inserted between said opposing surfaces and having opposite sides conforming in inclination to, and pressing against said opposing surfaces, and means for adjusting the position of said wedge member in a direction perpendicular to said upper surface of said table, thereby to adjust the position of said second jaw relative to said first jaw, wherein said second jaw is biased toward said jaw support by a biasing means acting between said second support mounting means and said jaw support in the direction of the slot.
