Manufactured by John H. Ferguson - Dayton OH

Manufactured by Ball Bearing Wrench Co. - New York NY

The object of the patent is rapid adjustment. The ball bearings at one end of the adjusting worm, and the spring and conical end of the the adjusting worm, allow the movable jaw to be slid "closed" without manipulating the adjusting worm. These same features bind the movable jaw against back movement. Ken Cope's "American Wrench Makers 1830-1930" shows an 1896 IRON AGE announcement for the wrench. A known example from the BALL BEARING WRENCH CO. matches that 1896 piece with markings for three patent dates: Sept. 4, '94 (525,435); Nov. 5, '95 (549,221); Dec. 1, '96 (this patent). Aspects of the wrench anticipate Wenger's subsequent patents (nos. 743,360 and 837,254). Also the subject of John Gardiner's improvement patent (no. 618,859) and W.M. Norcross' improvement patent (no. 618,899). Wenger applied the same general concepts to a "center screw adjust pocket wrench" in parallel patent no. 572,186. Both styles are shown in German patent DE-98590, Canadian patent CA-54,773 and British patent GB-189627293.

Listed in A List of Patents Issued by the United States, from 1790 to 1847, pgs. 185 & 563. Abstract: In the center of the instrument is an ordinary globe (terrestrial) as represented in the drawing No. 1, which accompanies this specification. To this globe a universal meridian, having a figure a at the top representing a traveler, and a similar figure at the bottom (not shown or necessary in the drawing) representing the antipodes to a. To this meridian is attached a broad plate representing the horizon to such figure, and marked It, h, in the drawing No. 1. The outer circles of the sphere represent the great circles in the heavens, together with the Tropics, the Arctic and Antarctic Circles. The stand and exterior semicircle serve to support the sphere, and to adjust it, as the semicircle slides through the support, and is fastened by a screw at s, as the instrument or sphere can be supported in various ways the manner is not essential. Claim: I claim the application of this instrument as a planetarium, by the introduction of wires representing the orbits of the planets and showing their nodes and inclinations, as explained in the specification. The instrument may be made of various materials, and mounted in a variety of forms, without affecting its essential qualities.
