Abstract

A vise has a jaw connected to a jaw support has a recess formed in a rear surface. A biasing member in the recess applies a force to the recess having a downward component to secure a workpiece to the vise. The biasing member may be the end of a set screw, a ball bearing or cam. The recess may be provided with an inclined surface to allow a horizontal force to be converted into a force having a vertical component.

Claims

1. A vise, comprising:

a base

a first jaw support on said base,

a first jaw attached to said first jaw support, said first jaw having a front face and a rear face, a recess in said rear face,

a second jaw support on said base,

a second jaw attached to said second jaw support, said second jaw having a front face and a rear face, a second recess in said rear face,

a first biasing member in said first jaw recess, said first biasing member applying a downward force on said first jaw,

a second biasing member in said recess of said second jaw, said second biasing member applying a downward force on said second jaw,

wherein

said first jaw support is fixed to said base,

said second jaw support is attached to a support base, said support base movable along said base,

a latch attached to said support base,

a series of apertures in said base, said latch engaging one of said apertures to secure said support base to said base.

2. A vise, comprising:

a base

a first jaw support on said base,

a first jaw attached to said first jaw support, said first jaw having a front face and a rear face, a recess in said rear face,

a second jaw support on said base,

a second jaw attached to said second jaw support, said second jaw having a front face and a rear face, a second recess in said rear face,

a first biasing member in said first jaw recess, said first biasing member applying a downward force on said first jaw,

a second biasing member in said recess of said second jaw, said second biasing member applying a downward force on said second jaw,

further comprising;

a groove in said base,

a link slidable received in said groove, said link having at least one aperture at one end and a slot at the other end,

a cam pivotally retained in said slot, said cam having an arm extending in said first cam recess,

said second jaw support engaging said at least one aperture in said link so that movement of said second jaw support causes movement of said link, and

a block extending through said slot and secured to said base.

3. The vise of claim 2, wherein

said second jaw engages said at least one aperture by being attached to a support base,

a latch connected to said support base and having a projection engaging said at least one aperture.

4. The vise of claim 3, wherein

said latch is pivotally connected to said support base.

5. A vise, comprising:

a base

a first jaw support on said base,

a first jaw attached to said first jaw support, said first jaw having a front face and a rear face, a recess in said rear face,

a second jaw support on said base,

a second jaw attached to said second jaw support, said second jaw having a front face and a rear face, a second recess in said rear face,

a first biasing member in said first jaw recess, said first biasing member applying a downward force on said first jaw,

a second biasing member in said recess of said second jaw, said second biasing member applying a downward force on said second jaw,

further comprising;

a groove in said base,

a link slidably received in said groove, said link connected to said second jaw support,

a cam having an arm extending into said recess of said first jaw, wherein

movement of said second jaw support causes rotation of said cam through said link, rotation of said cam causing a downward force to be applied to said first jaw.

6. A vise, comprising:

a base

a first jaw support on said base,

a first jaw attached to said first jaw support, said first jaw having a front face and a rear face,

a second jaw support on said base,

a second jaw attached to said second jaw support, said second jaw having a front face and a rear face,

a first biasing member in said first jaw support, said first biasing member applying a downward force on said first jaw causing downward movement of said first jaw,

a second biasing member in said second jaw support, said second biasing member applying a downward force on said second jaw causing downward movement of said second jaw further comprising;

a first recess in said first jaw rear face,

said first recess having an inclined surface, wherein said first biasing member applies force against said inclined surface.

7. The vise of claim 6, wherein said first biasing member is a ball bearing or spring loaded ball plunger.
