Milling vise

Claim 2

In a milling vise having base mounted guide means, a mounting surface on said base and opposed jaw members slideably mounted on said guide means, the improvement comprising; means interconnecting said jaw members and base for selectively effecting a collective adjustment of said jaw members in one direction along said guide means for vertical adjustment and in opposite directions along said guide means for effecting clamping adjustment whereby both jaw clamping and jaw adjusting movement take place along the same guide means.

Claim 3

The milling vise of claim 1 wherein said means include screw means; said screw means comprising a clamping screw threadedly engaged with said opposed jaw members and an adjusting screw threadedly engaged with said base and one of said jaw members.

Claim 4

A milling vise as defined in claim 2, wherein said clamping screw has threaded engagement with said jaw members with threading of opposite hand, respectively.

Claim 5

A milling vise as defined in claim 2, wherein said adjusting screw has threaded engagement with saw jaw memBer and base with threading of opposite hand, respectively.

Claim 6

A milling vise as defined in claim 2, wherein said base has a clearance hole disposed to receive the end of said clamping screw.

Claim 7

A milling vise as defined in claim 2, wherein said jaw members are disposed in a space defined by the periphery of said base projected perpendicularly thereto.

Claim 8

A milling vise as defined in claim 2, wherein said mounting surface normally engages the top of a supporting member, and said adjusting screw engages an overhanging portion of said base extending laterally beyond said supporting member for clearance of said adjusting screw.

Claim 9

A milling vise having a base with a mounting surface and provided with guide means, and also having opposite jaw members slideably mounted with respect to said guide means, wherein the improvement comprises: a clamping screw engaging said jaw members, exclusively, to generate clamping forces therebetween; and an adjusting screw having engagement with only one of said jaw members and with said base, said jaw members both being slideably mounted on the same guide means and wherein said guide means is in the form of at least two parallel rods, and said jaw members have gripping surfaces on the opposite side of said rods from said adjusting screw, and said device additionally includes nut means on said adjusting screw disposed to bear on the jaw member other than that in which said adjusting screw has threaded engagement in a direction to balance the moment induced by pressures of said gripping surfaces about the points of engagement of said clamping screw with said jaw members.

Claim 10

A milling vise having a base with a mounting surface and provided with guide means, and also having opposite jaw members slideably mounted with respect to said guide means, wherein the improvement comprises: a clamping screw engaging said jaw members, exclusively, to generate clamping forces therebetween; and an adjusting screw having engagement with only one of said jaw members and with said base, said jaw members both being slideably mounted on the same guide means and wherein said guide means is in the form of at least two parallel rods, and said jaw members have gripping surfaces on the opposite side of said rods from said adjusting screw, and said device additionally includes nut means on said adjusting screw disposed to bear on the jaw member other than that in which said adjusting screw has threaded engagement in a direction to balance the moment induced by pressures of said gripping surfaces about the points of engagement of said clamping screw with said jaw members.

Claim 11

The milling vise of claim 1 including an adapter including a block receivable between said jaws; and a holding bar adjustably secured to said block for adjustment in a direction parallel to the plane of separation of said jaws to establish a clamping action in a direction transverse to the clamping action of said jaws.

Claim 12

A milling vise including a pair of jaws moveably mounted on guideway means, and a clamping screw engaging said jaws, and also including positioning means for locating said jaws along said guideway means, wherein the improvement comprises: an adapter including a block receivable between said jaws, and a holding bar adjustably secured to said block for adjustment in a direction parallel to the plane of separation of said jaws to establish a clamping action in a direction transverse to the clamping action of said jaws and wherein said block and at least one of said jaws are normally interengaged with locking means separable in a direction parallel to said guideway means to fix said base against lateral displacement or rotation with respect to said jaws.

Claim 13

A milling vise including a pair of jaws moveably mounted on guideway means, and a clamping screw engaging said jaws, and also including positioning means for locating said jaws along said guideway means, wherein the improvement comprises: an adapter including a block receivable between said jaws, and a holding bar adjustably secured to said block for adjustment in a direction parallel to the plane of separation of said jaws to establish a clamping action in a direction transverse to the clamping action of said jaws and wherein said block and at least one of said jaws are normally interengaged with locking means separable in a direction parallel to said guideway means to fix said base against lateral displacement or rotation with respect to said jaws.
