SAFETY GEAR CASE.
The [Cleveland case] is made of aluminum, patent leather and transparent celluloid, and while it is a very light and attractive gear case, it is a desireable one, and wholly dust and storm proof.
The St. Louis Aluminum Casting Company is now showing its models of the 1898 Lu-Mi-Num. The special feature, which is rendered practical by the company’s special process of frame manufacture is the fixed gear case. This is an integral part of the frame, being cast in one piece with it. The back wall of the gear case takes the place of the right hand rear fork, thereby adding very materially to the strength of the frame. The front of the case is composed of a celluloid plate, which is sprung into it and fastened securely by two screws. It can be removed from its place readily, and consists of only three pieces. The celluloid being transparent, the working of the chain and sprocket may be seen, and the chain may be oiled from the top of the case, immediately over the front sprocket.
On the Special [Racycle] the gear case weighs only a few ounces more than the same model without it. The case consists of a section of D tubing, three-quarters inch wide, brazed on, and made part of the frame in place of the right side rear fork, which is dispensed with. The right hand rear stay, however, is carried down at an angle below the line of the rear wheel axle to the bottom part of the gear case, thus forming a brace for the upper and lower part of the gear case, and the gear case as thus constructed adds greatly to the strength of the entire frame. The sides of the gear case are made of transparent sheets of tough, pliable celluloid. They are strong enough to withstand any ordinary accident, and being detachable can be renewed at any time at a small cost. The construction of this frame and gear case is certainly unique and original, and may be said to be one of the few novel features shown in 1898.
The Centliver gear case, which is detachable and can be fitted to any make of bicycle, is made by the L. A. Centliver Manufacturing Company of Fort Wayne, Ind. This case is made entirely of metal. No rubber or leather is used in its construction. Sheet aluminum is used, shaped under heavy drawing presses, by which operation the metal gains great strength and rigidity, besides being lighter than any other metal or material that could be used. Cases are furnished either nickel-plated or enamelled, as preferred. The simplicity of attachment is remarkable, as it does not require any mechanic to attach it. Any one familiar with handling a bicycle can do it in a few minutes in the following manner: Remove the chain, then place the two parts together over the sprockets, forming an interlocking union. Set the case in position and adjust clamps. Replace the chain, inserting the chain bolt at front end by springing the case slightly. Keep the band in original shape. Be sure to have it in its proper place before tightening. The bolt can then be set with a small wrench.
The 1897 Humber had a metal case which very much resembled the metal cases used in England. This same case is furnished in 1898 by the Humber Company, and is a very practical one. It was quite largely used last year in New York and Brooklyn.
