The design improves Chadbourn's Band Cutter (patent no. 190,467) by adding a wire clamping spring and grooved slot on one jaw. Known examples have no visible markings. This structure would hold the cut wire so it could be safely discarded separately from the straw and grain. Early grain binders used wire bundle ties and contamination of grain and straw with bits of wire was a serious problem.

Manufactured by Stenz Wrench Co. - Ashland WI

Victor J. Evans - patent attorney This invention relates to a wrench of the quick-adjusting type, and more particularly to a wrench having a shank provided with serrations with which a cam-actuated clamping block is adapted to engage for holding the movable jaw in set position. The invention has for one of its objects to improve and simplify the construction and operation of devices of this character so as to be comparatively easy and inexpensive to manufacture, of durable and substantial design, and composed of few parts. Another object of the invention is the provision of a wrench having a serrated shank with which a serrated clamping block mounted on the movable jaw is adapted to engage for holding such jaw in fixed position, the block being operated by a pivoted cam that is held in locking position by a spring and is adapted to be retracted by a lever connected therewith when it is desired to adjust the movable jaw.

Manufactured by Wilcox Manufacturing Co. - Mechanicsburg PA

The patent is for a one- or two-piece forging forming the body of a screw-adjust nut wrench. Ken Cope's "American Wrench Makers 1830-1930" notes a 1905 Thomas Register entry which implies Wilcox was producing wrenches at Mechanicsburg, PA. Other directories list Wilcox as a manufacturer of drop forgings. A wrench identified as corresponding to this patent has no visible markings.

Manufactured by Tangye Brothers - Birmingham, county Warwick England

The innovation is a chain-and-pulley arrangement where the lifting force is inversely proportional to the difference in diameter of two pulleys, which are fixed to one another on the same shaft. Making the pulleys very close in size allows a very heavy load to be lifted by hand, and the friction in the mechanism is sufficient to prevent the load from falling under its own weight. A long loop of chain is wrapped around the two pulleys so that two loops of chain hang down. A third pulley is placed at the bottom of one of the loops and the load is attached to the body of that pulley. The remaining loop is used by the operator to raise or lower the load. The inventor exhibited an "Improved pulley block and lifting apparatus" at the 1862 International Exhibition in London. In 1864 he sold the patent rights to Tangye Brothers, who solved two key issues with Weston's invention: chain links were inconsistent in size and would not reliably wrap around a pulley designed to accept chain, and were also prone to getting wedged into the pulley block. Tangye Brothers developed a chain-link designed to easily disengage from the teeth of the pulley, and refined their production methods to produce links of consistent size. See also patent GB-186,502,931 for additional improvements.
