Sa grandeur est une possibilité de cotiller tout en gardant la puissance de freinage activée, et une autre isla non-responsabilité d'appliquer le frein en pédalant sans soin, alors que l'absence de tout tremplin bien sûr une grande avancée.

The Wheel and cycling trade review . rsal. Its greatmerit is a possibility of coasting while stillkeeping the brake power on, and another isthe non-liability to apply the brake by care-less pedaling, while the absence of all springsis of course a great advance. Last year, in my description of the variousnovelties to be seen at the National Show, Ialluded to a couple of hydraulic brakes whichthe Osmond people and Mr. Terrill, Q. C.—since so well known in connection with hisconduct of tire patent actions—intendedto market. None of these, however, came toanything, and the idea seemed to havedropped quite out. On the stand of Messrs.Cogswell & Harrison, a noted arms manufac-turing concern who have recently gone intothe cycle building business, at the recent Na-tional Show, was found a really efficientbrake of this description, which I illustrate.As will be seen, it is operated on by the usualbrake lever acting on the piston plunger of asmall cylinder, A. This similarly reflectsalong a minute copper connecting tube on. the cylinder B, depressing C, which is a longpiece of patent leather forming a sectionalpart of the ordinary mudguard, on to thedriving tire from the hinge D. The wholeaffair was neat-looking, instantaneous in ac-tion and very powerful because of the largebraking surface secured. Another point of novelty I found on thesame stand was a new method of fixing disc-adjusting bearings in hub and crank-hanger, which is illustrated herewith. It is merely asmall pin attached to a flat steel spring whichis screwed fixed to the hub or hanger asshown. This small pin engages in slots or grooves cut out of the outer circumference ofthe adjusting discs as shown in fig. 3. Ofcourse the method is very simple, is what youwould call foot-proof, but as no circumferen-tial support is given the discs beyond thatwhich they get from the engagement betweenthe male and female threads, it will be foundthat after some months of use the discs rock
