Abstract
Abstract A machine vise has a base plate which rests directly on a grooved machine table and is rotatable about a bearing collar secured by a vertical screw to the machine table, being fastened in any desired position by paws which engage laterally-projecting rails on the edge of the base plate and are screwed to blocks fitted in the grooves of the machine table. A spring-loaded stop engaging a gear ring fixed to the bearing collar serves to locate the base plate in the desired angular position and the base plate can be further clamped in position by a screw ring on the bearing collar.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
249 words
A machine vise for mounting on a machine table having a plurality of grooves therein each having inwardly extending flanges adjacent the upper edge thereof, comprising: a base plate having laterally projecting edge rail means; vise means mounted on said base plate; a hollow cylindrical bearing collar adapted to support said base plate for rotation with respect to said machine table to a selected angular position, said bearing collar having means defining an external thread thereon; means defining an externally threaded holding screw received in the interior of said hollow cylindrical bearing collar and being freely accessible from above, and holding screw including holding block means threadedly engaged therewith, said holding block means being received in one of said grooves on said machine table to effect a securement of said bearing collar to said machine table, said holding block means including means for permitting a movement of said holding block means longitudinally of said groove when said holding screw is loosened and for preventing an upward movement out of said groove; an internally threaded nut threadedly engaged with said external thread on said bearing collar, said nut engaging the upper surface of said base plate so that said base plate will be clamped between said base plate and said machine table; and clamping means receivable in said grooves and including means for engaging said edge rail means so that said edge rail means of said base plate are clamped between said machine table and said edge rail engaging means.
Claim 2
Dependent Claim
249 words
A machine vise for mounting on a machine table having a plurality of grooves therein each having inwardly extending flanges adjacent the upper edge thereof, comprising: a base plate having laterally projecting edge rail means; vise means mounted on said base plate; a hollow cylindrical bearing collar adapted to support said base plate for rotation with respect to said machine table to a selected angular position, said bearing collar having means defining an external thread thereon; means defining an externally threaded holding screw received in the interior of said hollow cylindrical bearing collar and being freely accessible from above, and holding screw including holding block means threadedly engaged therewith, said holding block means being received in one of said grooves on said machine table to effect a securement of said bearing collar to said machine table, said holding block means including means for permitting a movement of said holding block means longitudinally of said groove when said holding screw is loosened and for preventing an upward movement out of said groove; an internally threaded nut threadedly engaged with said external thread on said bearing collar, said nut engaging the upper surface of said base plate so that said base plate will be clamped between said base plate and said machine table; and clamping means receivable in said grooves and including means for engaging said edge rail means so that said edge rail means of said base plate are clamped between said machine table and said edge rail engaging means.
Claim 3
Dependent Claim
59 words
A machine vise according to claim 1, including a gear ring having teeth thereon tightly fixed to said bearing collar, said gear ring having a lower side approximately flush with the lower surface of said base plate, and a movable stop member mounted in said base plate and being movable into and out of engagement with said gear ring.
Claim 4
Dependent Claim
41 words
A machine vise according to claim 2, wherein said lower side portion of said gear ring is recessed in its mid-region whereby only a narrow outer annular surface of said lower side of said gear ring rests on said machine table.
Claim 5
Dependent Claim
43 words
A machine vise according to claim 2, wherein said gear ring has a scale disc thereon and an angular scale on the periphery of said scale disc, and means defining sighting windows in said base plate with null marks for the angular scale.
Claim 6
Dependent Claim
66 words
A machine vise according to claim 2, wherein said stop member comprises a longitudinally movable, spring loaded stop pin having rack teeth thereon and said base plate includes means defining a spindle rotatably mounted thereon, said spindle extending at right angles to said stop pin and having pinion teeth engaging said rack teeth to enable withdrawal of said stop pin from engagement with said gear ring.
Claim 7
Dependent Claim
41 words
A machine vise according to claim 2 including a support ring received in means defining a recess of said base plate, said teeth of said gear ring overlapping said support ring whereby said gear ring is held within the base plate.
Claim 8
Dependent Claim
34 words
A machine vise according to claim 1, wherein said base plate has at each end longitudinal grooves in its under-side for the reception of groove blocks mounted in said grooves on said machine table.
Claim 9
Dependent Claim
38 words
A machine vise according to claim 7, wherein said base plate has at each end recesses for receiving clamping screws engageable with said groove blocks in said machine table to secure the base plate in its zero-angle position.
