Abstract:
A bar clamp extension apparatus for extending the working length of a bar clamp, the bar clamp including a primary bar and a fixed jaw that is releasably mounted on the distal end of the primary bar, wherein the fixed jaw is removed from the primary bar, the extension apparatus is attached to the distal end of the primary bar, and the fixed jaw is attached to the distal end of the extension apparatus, the extension apparatus comprising:a. an extension bar having a proximal end section and a distal end section; b. a pin projecting from either side of the distal end section of the extension bar for releasably attaching the fixed jaw of the bar clamp; c. a pin projecting from either side of the proximal end section of the extension bar; and d. a coupler associated with the proximal end section of the extension bar for releasably attaching the proximal end section of the extension bar to the distal end of the primary bar in longitudinal alignment therewith; the coupler comprising: i. a pair of plates positioned in contact engagement on either side of the proximal end of the extension bar and of the distal end of the longitudinally aligned primary bar; ii. recesses in said plates for capturing the pin projecting from either side of the proximal end of the extension bar; and iii. means interconnecting the pair of plates for applying clamping pressure to hold the pair of plates in contact engagement with the primary bar and the extension bar.
