Manufactured by Est. Martin s.p.r.l. - Grand-Rechain Belgium

This truing fixture for bicycle wheels remains popular decades after its introduction in the mid-1960s. It seems that production has largely ceased although the original manufacturer remains in business. Original examples are prominently marked with the patent number ("672210") in multiple places. The truing gauge, with its pair of dials showing lateral and radial runout, allows the bicycle mechanic to adjust the wheel to round in just a few minutes. The original manufacturer was Ets. Martin s.p.r.l. The "Ets." part is short for "Établissements" and "s.p.r.l." is short for "Société Privée à Responsabilité Limitée". Together, they suggest that this was (and is) a small business organized as a limited liability corporation. The business is still active as of 2025 and although their website mentions the PreciRay there is no indication that it is still available.

Manufactured by Farrel Foundry & Machine Co. - Ansonia, New Haven County CT
Assigned to Farrel Foundry & Machine Co. - Ansonia, New Haven County CT

Abstract: My invention is applicable to two-roller mills, and has for its object to provide simple, strong, and durable means for raising the upper roller in use. It will be understood by those familiar with this class of machinery that owing to the enormous weight of the rollers there is great wear upon the lower journal-boxes of the upper roller and a constant tendency of the upper roller to settle o down upon the lower roller, so that the weight of the upper roller, instead of resting wholly upon its journal-boxes, rests partially and sometimes entirely upon the lower roller. Claim: In a cane-mill, the combination, with the lower roll, of the upper roll operating by its weight to crush material against the former, a supporting-frame having stationary bearings for the lower roll, horizontal recesses 14, and vertical recesses open at the top, movable bearings 8, engaging the edges of the latter recesses, cap-plates 9, wedges 12, situated in the recesses 14, screws 17 engaging said recesses and having collars 19, removable plates 13, situated between said collars, and means for securing said plates to the frame.
