Abstract
Abstract The invention relates to a metal clamp for circular tubing composed of a band formed exactly to the final diameter required. At the ends of the formed loop the band is formed to provide flanges and at one end a tongue that penetrates a slot in the opposed flange. The flanges are drawn together by means of a bolt passing through box sections butressing each flange.

Claim 1
Independent Claim
139 words
A pipe clamp comprising a length of flexible metal band, having a constant width throughout its length, bent into circular form, the ends of the band being bent into outwardly directed radial flanges, a bracing member abutting each flange and the outer surface of the band, a bolt passing through the bracing members and flanges, a tongue pressed out of the material of one flange to define a slot, one end of which passes over and bears on the bolt, a second slot in the other flange one end of which passes over and bears on the bolt and the other end of which extends into the circular portion of the band, the tongue passing through the second slot so that when the flanges abut, the circular portion of the band and the tongue form substantially a perfect circle.
