Manufactured by Miller and Silverman - Syracuse NY

The ratchet wrench in this patent has an internal pawl as in Miller's previous ratchet patent (no. 845,716, dated Feb. 26, 1907). This patent has the body of the wrench made of two cast parts, and has a socket on the end of the handle to hold wrench sockets, screwdriver bits, etc. Each of the sockets and other tools that fit this ratchet head has a separate spring to grip the opening in the ratchet head. This form of Charles Miller's ratchet wrench is shown as part of the MILLER COMBINATION TOOL SET produced by Miller and partner Levi L. Silverman. It was the subject of a lawsuit filed by Silverman against Miller after Silverman bought out Miller's interest in September, 1905 (Silverman v. Miller 190 NY 504 )

A sliding pivot point and a set of notches with a corresponding spur form the adjusting means on this pliers type wrench. Used with Bradley's Sept. 22, 1874 patent (no. 155,139) for a malleable iron adjustable wrench. Some wrenches marked with this patent date include screw adjustment similar to 166,020 or 206,733. Some known examples with a marking that appears to read "PAT'D JUNE 24 72" match the drawing in pat no. 155,139, with an alignment tongue on the handle with the gripping tooth. Other known examples bear names of farm implement companies, etc. For the overall form, also compare patent nos. 166,020 and 206,733.

Manufactured by R W Ammons - Los Angeles CA

The wedge shaped "fixed" jaw has a central bore for passage of lubricant. The end with the "spreader" can be adjusted to compensate for different widths of springs by a clamping nut and wedge teeth that engage the base of the frame. The "spreader" is a circular piece eccentrically mounted on a shaft; the edge ranges from thin to thick. The shaft holding the spreader extends some distance beyond the frame base and the portion extending beyond the frame is hexagonal. An auxiliary wrench (fig. 4 in the drawings) operates the shaft with the "spreader" and also is used to loosen and tighten the clamping nut. An example of the auxiliary wrench is known, marked "T5 - R W AMMONS L.A. CAL / PAT PEND"
