Le bloque-patins CHOLAIN

[Ebykr summary; the article’s text is not reproduced. The Établissements Cholain of Paris are said to have specialized in a series of practical novelties worth the attention of dealers and users alike, and the article proposes to review the most interesting of them, the Cholain shoe-locking device being one. Every dealer knows how hard it is to fit and adjust a brake cable. This device locks the brake shoes against the rim at once, leaving both hands free to adjust the cable quickly and easily.]

[Ebykr summary, after the engraving. The device is described as quite simple: two jaws whose bases slide one upon the other to give the opening wanted and are brought back to the gripping position by a coil spring on which they are threaded. A ring, as the engraving shows, makes the tool very easy to handle. The whole is called robust, the jaws being case-hardened and tempered and the entire piece cadmium-plated.]

[Text article set in italic roman type under a title in roman type, the word CHOLAIN in heavy capitals, with one line engraving across the middle of the column. The engraving is drawn largely in dotted outline: it shows a brake fork with the caliper arms, a bolt and a cable clamp in dotted lines, and in solid shaded lines the locking device itself, two jaws with notched ends, a coil spring between them and a round ring at the right, with a second dotted ring beside it. No caption, signature or agency mark appears.]
