La roue libre HIRY’S à roulement annulaire

[Ebykr summary; the article’s text is not reproduced. The author states that in bicycle manufacture the ring bearing (roulement annulaire) now tends to supplant the cup bearing (roulement à cuvettes), as it did earlier in automobiles and motorcycles, a logical trend since the cycle could not fail to follow progress. The Hiry’s triple and quadruple freewheel with ring bearing is said to be the only one existing in the world. It is a somewhat revolutionary design that calls for the explanation below. It screws onto all hubs of current manufacture like an ordinary freewheel. For a small repair or a simple cleaning of its interior it comes apart instantly, without unscrewing the hub’s freewheel body (noix du moyeu). The procedure follows.]

1° A l’aide d’une clef à molette dévisser l’écrou portant la marque Hiry’s (le sens de dévissage est celui de la rotation des aiguilles d’une montre).

2° L’écrou enlevé, tirer à soi les pignons dentés. Ceux-ci et le roulement annulaire viennent alors dégageant complètement la noix porte-cliquets. Pour le remontage, faire les opérations inverses de celles ci-dessus après avoir pris soin, évidemment, de maintenir les cliquets et les ressorts au fond de leurs emplacements respectifs (on y arrive facilement en se servant d’une pince en forme de fer à cheval faite avec un vieux rayon).

Ensuite, bloquer fortement l’écrou.

Le dévissage de la roue libre du moyeu se fait en deux temps :
1° Oter les pignons dentés comme il est dit ci-dessus dans le cas d’une réparation ;
2° Prendre la noix porte-cliquets entre les mors d’un étau et la dévisser comme une noix de roue libre ordinaire.

[Ebykr summary, closing paragraph. The author warns that the nut bearing the Hiry’s mark must never be used to unscrew the freewheel directly from the hub. The freewheel is a specialty of the Maison Bourrin Frères of Saint-Etienne, a firm founded in 1902 that has always kept the favor of a numerous and faithful clientele, and the ring-bearing freewheel is a creation of high technical quality.]

[A single column of text with one illustration. The heading is set flush right in heavy bold roman type with HIRY’S in capitals. The opening paragraphs are justified italic roman type, with the name Hiry’s and the firm name Bourrin (small capitals) in upright roman type among the italic lines. Midway down, a square panel framed by a thin black rule holds a line engraving with fine hatching of a freewheel cluster seen obliquely from the left, a stack of toothed sprockets of decreasing size with rounded tooth cut-outs; the small ring face on the left carries engraved lettering that reads BREVETÉ, S.G.D.G. and HIRY’S with a word ending in MONTAGE across the top. The engraving carries no artist signature. The numbered steps resume below the panel and a small open black circle, the closing ornament of the article, is centered under the last line. At the very foot of the crop the heading of the next notice, Les carters JOURLAIT, begins and is clipped.]
