Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
219 words
In a work bench for supporting a power tool in operative positions for performing a variety of operations on a workpiece, the improvement which comprises: a workpiece supporting surface, said supporting surface having a first elongated slot opening therethrough and a second elongated slot opening therethrough oriented with its lengthwise dimension at substantially right angles to the lengthwise dimension of said first slot; power tool support frame means formed by opposed side and end members of equal lengths to form a square opening over said support surface with certain of said members of said frame means being parallel to one slot and certain others of said members of said frame means being parallel to the other slot; means attaching said frame to said supporting surface in spaced relation therefrom and in position to encompass said first and second slots; power tool guide means; and means connecting said power tool guide means to said frame means in selective positions of alignment with said first and second slots to position the power tool to perform an operation on a workpiece positioned on said supporting surface adjacent the selected position of said power tool guide means, said means connecting said power tool guide means to said frame means being interchangeably supported by said side and end members adjacent one of said slots.

Claim 3
Dependent Claim
63 words
The work bench improvement set forth in claim 1, wherein said power tool support frame includes opposed side and end members of substantially equal lengths connected to form four corners, said attaching means being operatively disposed at each of said corners, and said means connecting said carriage means to said frame means includes mounting blocks selectively engageable with said side and end members.
Claim 4
Dependent Claim
57 words
The work bench improvement set forth in claim 1, wherein said power tool guide means includes spaced track elements supported by and between said mounting blocks in positions to straddle said slots; and means securing said track elements to said mounting blocks to permit selective spacing between said track element and straddle location relative to said slots.
Claim 5
Dependent Claim
126 words
The work bench improvement set forth in claim 1, wherein workpiece guide means is carried by said supporting surface, said workpiece guide means having elongated slots therein, said supporting surface having a pair of elongated secondary slots therein arranged substantially parallel to each other and to one of said first and second slots and being spaced apart to straddle the other of said first and second slots, and releasible securing means interconnects said workpiece guide means and supporting surface through said elongated slots in said workpiece guide means and said secondary slots to permit adjustments between said workpiece guide means and said first and second slots, whereby said workpiece guide means may be located at selected angular positions relative to said first and second slot openings.
Claim 6
Dependent Claim
187 words
In a work bench for supporting a power tool in operative position for performing a variety of operations on a workpiece, the improvement which comprises: a workpiece supporting surface, said supporting surface having a first elongated slot opening therethrough and a second elongated slot opening therethrough and oriented with its lengthwise dimension substantially at right angles to the lengthwise dimension of said first slot; power tool supporting frame means attached to said supporting surface in spaced relation thereover and positioned to encompass said first and second slots; power tool guide means; means connecting said power tool guide means to said supporting frame in selective positions of parallel alignment with respect to said first and second slots for positioning the power tool to perform an operation on a workpiece located on said supporting surface over at least one of said elongated slots; and workpiece guide means carried by said supporting surface and including a pair of fences adjustably secured to said supporting surface in spaced relation to straddle one of said elongated slots and to be movable along the length of the other one of said elongated slots.
