US Patent: 1,161,777 http://www.datamp.org/patents/displayPatent.php?id=40934&pn=1,161,777 Pipe Wrench Patentee: John La Rock - Chicago IL Granted:1915-11-23
Manufactured by Mechanical Specialties Company - Chicago IL
Assigned to Terence F. McKenna - Chicago IL

Compound leverage tongs type wrench; the advantage is ability to grip and turn pipe very close to walls, or other closed-in situations. The jaws are thin at the ends, and enclose slightly more than half the circumference of a pipe. The wrench fits a predetermined size, so a range of pipe sizes would require several wrenches. The specifications note the leverage is sufficient to have the jaws adapted to form hoof nippers. Contemporary advertising suggests the primary use for the wrench was in conjunction with electrical conduit. Known example marked LAROCK WRENCH 1 IN is approx. 16 1/2 inches long.
