THE MECHANICAL SIDE.Novelties in Construction Seen at the Show...
Construction of Frames.
The frame usually consists of seven or eight pieces of tubing, brazed to either drop forged or sheet metal connection. After the bicycle frame is enameled it is extremely difficult to say what these connections are. Originally all bicycles were built with drop forged connections, or connections made from steel castings. During the past year or two sheet steel stampings have been largely used.
The Pope Manufacturing Company has always used steel forgings, and shows samples of their forgings in the rough which weigh fifteen and a half pounds to the set. This same set, when finished, weighs five pounds.
The Western Wheel Works, the makers of the Crescent, use stampings altogether, even going so far as to make their sprocket of a stamping.
The Gendron and Lyndhurst Companies use what is known as the lap-raising system, doing away with both forgings and stampings.
There exists also a great variety of fork crowns. The Pope Company uses a plain single crown. The Liberty Company shows a stamped double hollow crown. The Orient Company uses a double-truss crown.
Nearly all the makers are using reinforced joints, many of them using them on the exterior as well as the interior of the tube.
Among the novelties in rear forks is a bicycle exhibited by George Hendee, the old racing champion, having a four-and-a-half-inch tread, and which is accomplished by using one-and-an-eighth-inch D-shaped tubing. The United States Cycle Company also exhibits a D-shaped rear fork construction.
The Stearns Company builds its racing wheel and a special road wheel having ovoid-shaped rear forks, and thus dispenses with the usual offset on chain side. The Classic, built by Louis Rosenfeld & Co., also has ovoid tubing for its rear forks. The Peerless Manufacturing Company also shows a model having D-shaped rear forks.
The National Bicycle exhibits show what they call a rear fork stiffener, which consists of a double section of stampings brazed together, which are brazed into the crank hanger and carry the usual offset, so that the rear forks fit into the stampings and run straight from the stampings to the rear axle.
The Fox Machine Company uses what it calls increased tubing in the tube that runs from the crank axle bracket to the seat pillar. The tube is of a diagonal shape a the bottom, where it measures 1½ inches, and tapers to 1 1/8 inches at the top, where it is perfectly concentric.
The Premier Company builds its frame entirely of what is known as helical tubing. This differs from the cold-drawn tubing by being spirally drawn and twisted.
The frames of the Spalding bicycle are made of swaged tapered tubing, which is large in the centre, and tapers with increased thickness of gauge toward the ends, giving great strength at the joints.
The Keating frame has the diagonal stay curved just before it reaches the bottom bracket.
Ladies' wheels of the drop-frame pattern may be classed as being about in four styles. The Columbia, Liberty, and Wolf show them with the double-curved loop frame, many of the other makers showing them with both main tubes perfectly straight from the head to the crank bracket, and others varying these by making the lower tube straight and the upper tube curved.
The Aluminum Company shows a ladies' wheel having only one tube from head to bracket, cast entirely of aluminum.
The Eagle ladies' wheel carries two upper tubes side by side, in addition to the straight lower one.
In the Keating ladies' wheel the upper tube is so curved over the crank hanger that it makes the diagonal upper stay out of the same piece of tubing.
One of the most original frame constructions shown is the Owen pyramid, which is a realization of C. E. Duryea's idea. The frame is shaped like a triangle, the saddle being to the apex of it. It is mounted and steered like the regular pattern safety, but it looks as if it might be eccentric in its steering...
The makers of the Classic show an eccentric chain adjuster, which, instead of being operated at the rear axle, as usual, is operated at the crank hanger.
The frame of the men's Luminum bicycle is cast in one piece, and is said by experts to be the most remarkable casting of an aluminum alloy ever produced.
During the continuance of the show THE NEW YORK TIMES will publish daily detailed descriptions of the various parts that go to make up a complete bicycle...
