1. A tool holder support assembly, comprising:
- a first support member having a dovetail projection protruding from a first support surface and extending lengthwise in a first direction, said dovetail projection including a pair of opposed sloped surfaces extended in said first direction and converging toward said first support surface to define, in part, a cross section of said dovetail projection;
a second support member having a second support surface with a dovetail slot formed in said second support surface, said dovetail projection of said first support member being slidably engageable in said dovetail slot with said second support surface adjacent to said first support surface, a lateral opening in said second support member extending transversely to and intersecting said dovetail slot to expose a portion of one of said sloped surfaces of said dovetail projection when said first and second support members are slidably engaged;
a wedge member inserted in said lateral opening and having a wedge surface movable translationally without rotation to make contact with said one exposed sloped surface of said dovetail projection, pressing said wedge surface against said one exposed sloped surface causing, by wedge action, said first support surface to press against said second support surface, whereby said first and second support members are releasibly fixed relative to each other; and
driving means for translating said wedge surface without rotation to press against said one exposed sloped surface of said dovetail projection.

Abstract
In a tool holder support assembly, a horizontal slide member connects to a machinery table with a T-slot connection, and a vertical support post connects to the slide member with a sliding dovetail joint. The slide member and post are fixed together by a wedge that extends from the post and presses transversely against a sloped surface of a dovetail protrusion on the sliding member, when a bolt is rotated. The slide member is fixed to the machining table by engaging a nut located in the T-slot with a bolt passed through the slide member. Alignment is provided between the machining table and slide member by abutting external surfaces.

8. A device for connecting to a dovetail protrusion extending from an object, comprising:
-
a body member having an elongated dovetail slot in a first surface thereof for mating with said dovetail protrusion, said dovetail slot extending in a first direction, and including a pair of opposed sloped surfaces extending in said first direction and diverging away from a second surface to define, in part, a cross section of said dovetail slot, an opening in said body member extending in a second direction transverse to and intersecting with one of said sloped surfaces of said dovetail slot, whereby said slot and said opening are joined; a wedge member inserted in said opening and having a wedge surface substantially parallel with said one intersected sloped surface of said dovetail slot, said wedge member being movable translationally without rotation in said opening in said transverse direction to extend said wedge surface beyond said opening and into said slot, driving means for translationally moving and extending said wedge surface without rotation into said slot, whereby said wedge surface may press against said dovetail protrusion located within said dovetail slot and fix said body member relative to said dovetail protrusion.
