Abstract
Abstract This clamping device includes a first angle bracket having a slotted outstanding vertical leg and a second angle bracket having a slotted outstanding horizontal leg. The second bracket is movably mounted to the outstanding leg of the first angle bracket and a C-clamp is mounted to the outstanding leg of each bracket. Each C-clamp includes a fixed, outwardly extending, threaded rod, which is received within the slot of the outstanding leg of its associated bracket for translational movement of the clamp along the length of the slot, and also perpendicularly of the slot, and rotational movement of the clamp about the axis of the rod.

Claim 1
Independent Claim
418 words
An adjustable clamping device for attachment to a base, the device comprising: a. a first angle bracket including an attachment leg for attachment to the base and a substantially perpendicular outstanding leg having an elongate slot therein, b. a second angle bracket including an attachment leg for attachment to the outstanding leg of the first angle bracket and a substantially perpendicular outstanding leg having an elongate slot therein, c. fastener means connecting the attachment leg of the second angle bracket to the outstanding leg of the first angle bracket, d. a first clamp including: 1. a substantially U-shaped body having opposed arms, 2. a threaded clamping member having a clamping axis extending between said arms, 3. an elongate, threadedly adjustable member having a longitudinal axis and having one end secured to the body and the other end received by the slot in the outstanding leg of the first angle bracket for selective translational and rotational movement of said adjustable member in said slot to move the first clamp for a relative coarse sliding adjustment toward and away from the outstanding leg of the second angle bracket and to rotate the clamping axis in a plane substantially perpendicular to the longitudinal axis of said adjustable member, and 4. means for selectively fixing the location of the adjustable member in said slot and for enabling movement of the adjustable member and first clamp for a relative fine threaded adjustment toward and away from the outstanding leg of the first bracket to which it is attached, and e. a second clamp including, 1. a substantially U-shaped body having opposed arms, 2. a threaded clamping member having a clamping axis extending between said arms, 3. an elongate threadedly adjustable member having a longitudinal axis and having one end secured to the body and the other end received by the slot in the outstanding leg of the second angle bracket for selective translational and rotational movement of said adjustable member in said slot to move the second clamp for a relative coarse sliding adjustment toward and away from the outstanding leg of the first angle bracket and to rotate the clamping axis in a plane substantially perpendicular to the longitudinal axis of said adjustable member, and 4. means for selectively fixing the location of the adjustable member in said slot and for enabling movement of the adjustable member and second clamp for a relative fine threaded adjustment toward and away from the outstanding leg of the second bracket to which it is attached.
