Abstract
Abstract A work table arrangement in which a C or U-shaped frame supports a work plate and two clamping plates. One of the clamping plates may be positioned in the frame at predetermined increments to provide coarse adjustment. The other clamping plate is supported by the frame through a threaded screw mechanism which allows the clamping plate to be forced under pressure against the cooperating plate. The screw mechanism provides for fine adjustment. The clamping plates may be supported by the frame so that they face each other and move toward each other or their movement is in opposite directions.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
175 words
A work table for clamping against planar surfaces comprising, in combination, a substantially open-loop-shaped frame member; a work plate on said frame member; two clamping plates arranged on said frame member with at least one clamping plate being movable with respect to the other plate, said frame member having two insertion openings for mounting one of said clamping plates in opposite directions, the other one of said clamping plates having a threaded spindle; two threaded screw means for receiving and mounting said spindle of said other clamping plate, each of said screw means corresponding to one respective insertion opening, each screw means and respective insertion opening being spaced directly across from each other, said clamping plates being movable toward each other for applying clamping forces directed toward each other when said clamping plates are in one respective insertion opening and threaded screw means, said clamping plates being movable away from each other for applying clamping forces directed away from each other when said clamping plates are in the other respective insertion opening and screw means.
Claim 2
Dependent Claim
175 words
A work table for clamping against planar surfaces comprising, in combination, a substantially open-loop-shaped frame member; a work plate on said frame member; two clamping plates arranged on said frame member with at least one clamping plate being movable with respect to the other plate, said frame member having two insertion openings for mounting one of said clamping plates in opposite directions, the other one of said clamping plates having a threaded spindle; two threaded screw means for receiving and mounting said spindle of said other clamping plate, each of said screw means corresponding to one respective insertion opening, each screw means and respective insertion opening being spaced directly across from each other, said clamping plates being movable toward each other for applying clamping forces directed toward each other when said clamping plates are in one respective insertion opening and threaded screw means, said clamping plates being movable away from each other for applying clamping forces directed away from each other when said clamping plates are in the other respective insertion opening and screw means.
Claim 3
Dependent Claim
15 words
The work table as defined in claim 1, wherein said frame member is substantially C-shaped.
Claim 4
Dependent Claim
15 words
The work table as defined in claim 1, wherein said frame member is substantially U-shaped.
Claim 5
Dependent Claim
124 words
The work table as defined in claim 1 including an extension member attached to one of said clamping plates, said frame member having a leg terminating in an opening for receiving said extension member of said clamping plate, said leg of said frame member being parallel to the core axis of said frame member, said frame member having a second leg with a threaded opening; a threaded shaft member attached to the other one of said clamping plates and rotatable within said threaded opening of said second leg, said second leg having an auxiliary threaded opening spaced from said first-mentioned threaded opening, and said leg for receiving said extension member having an auxiliary opening spaced from said first-mentioned opening for receiving said extensiOn member.
Claim 6
Dependent Claim
18 words
The work table as defined in claim 1, including elastic cap means for substantially enclosing said clamping plates.
Claim 7
Dependent Claim
19 words
The work table as defined in claim 1, including a plate member of wood-like material on said work plate.
Claim 8
Dependent Claim
17 words
The work table as defined in claim 1 including means for holding tools on said work plate.
Claim 9
Dependent Claim
21 words
The work table as defined in claim 1 including support means attached below said work plate and reaching towards the ground.
Claim 10
Dependent Claim
30 words
The work table as defined in claim 4 wherein said clamping plates have rectangular-shaped clamping surfaces, said extension member and said opening for receiving said extension member having rectangular-shaped cross-sections.
