Description: |
| "Geared" rollers to form crimps in sheet metal pipe, etc. The rollers are advanced by ratchet action of a pawl, and the distance between the rollers can be adjusted.
Two forms of the tool are shown in period advertising; a stand-alone tool and a second form integrated with a snips or shears (viz. pat. no. 570,218). In early 1894, Peck, Stow & Wilcox was marketing the tool as "BLUMER'S HAND CRIMPER" with a cam lever to separate the rollers, and a fixed "gauge." The tool also appears in a 1917 hardware wholesale catalog among other tinsmith's tools. |
