Manufactured by Novelty Rack Company - London England

Wrench opening size adjusted by sliding "plates or strips." Ron Geesin's THE ADJUSTABLE SPANNER shows a couple of variant markings on examples of this wrench produced as THE AUTOMATIC by Funt's Novelty Rack Company. Corresponding German patent DE-92949 was granted with effective date June 25, 1896. Compare U.S. patent 562,709. Note: Early British patents (pre 1916) were numbered by the year and started at patent #1 at the start of each year in January. The patent # used in DATAMP represents the year of registration and the patent # (with "leading zeros" interposed to make the number nine digits). This patent is #12331 of the year 1896.

Abstract: The object of my invention is to produce a machine-tool for upsetting the saw- teeth, which will operate rapidly and more regularly than the work can be done by hand-hammering. The machine consists, essentially, of a frame, a vertical reciprocating shaft, on the lower end of which the upset is formed, and clamping-dies held within the frame and adapted to clamp and hold the saw and support the tooth during the operation of the upset-tool. The clamping-dies may be adjusted by hand, so as to clamp the saw and support the tooth each time a tooth is operated upon, or the clamping-dies may be operated by means of the automatic attachment set forth, so as to automatically clamp the jaws each time the upset operates. The power required is given the upset by means of an eccentric cam at the end of a lever. Claim: In a saw-tooth-upsetting machine, the combination of a sawtooth upset having the operating-surfaces inclined to correspond with the front and back surfaces of the saw-tooth, an extension or holder sliding in guide-bearings in the frame and guided in a right line therein reciprocally toward the cutting-edge of the saw-tooth, the said guide-bearings, the said frame, and sawtooth dies having parallel and smooth or rough blade-clamping surfaces and inclined diverging surfaces adjacent the sides of the tooth-point, the said frame serving to support or hold all of the parts of the device.

Assigned to Detroit Machine Screw Works - Detroit, Wayne County MI

Abstract: My invention relates to screw-cutting machinery, and has for its object a novel machine for cutting a continuous thread upon conical tubular articles and it consists, essentially, of suitable mechanism for cutting the threads and for feeding the work to and from the cutter, and for rotating the work in connection therewith. Claim: In a machine for screw-threading tapering bushings, the combination, with a rotating multiple cutter, of a rotating chuck carrying the bushing, said cutter and chuck being set at an angle to each other, so that the tapering bushing at the point of contact with the cutter will be in the same plane therewith.
