Patent no. 358849 granted on June 30, 1936.
The principal objects of this invention are to provide a bicycle of an unusual novel and attractive appearance which will have a distinct appeal to the eye in conformance with the line adopted in the streamlining of vehicles and further, to utilize the streamline effect of design to accomplish a very distinct improvement in the riding qualities of the bicycle to effect the absorbing of road shocks and further, to provide a very desirable form of bicycle having a distinctly novel appeal. The principal features of the invention consist in the novel construction of the main frame whereby the upper bar is curved to meet the rear ends of the lower fork and to form a continuous part therewith and the front forks are curved downwardly with their lower ends bent rearwardly to form a resilient front support corresponding in part with the resilient rear fork.
In the accompanying drawings, Figure 1 is the side elevational view of my improved streamlined resilient bicycle. Figure 2 is an enlarged sectional view through the fork head of the front fork. Figure 3 is a side elevational view of the frame connections at the juncture of the top bar and upper end of the rear fork. Figure 4 is a sectional front elevational view of the upper rear fork connection shown in Figure 3. Figure 5 is an enlarged side elevational detail of the rear wheel support.
Figure 6 is a longitudinal sectional view through the structure illustrated in Figure 5.
In the manufacture of bicycles, it has been the practice for many years to construct the frame in accordance with a "standard" pattern which in side elevation is substantially diamond-shape or of a rhomboid formation with the rear forks extending substantially horizontally from the crank bracket and mating the rear braces or upper forks at an acute angle where the axle of the wheel is mounted in slotted brackets and the front forks of said "standard" type of bicycles slope straight down from the head or front end of the frame having a slight curve forward for the castor effect. In the "standard" type of bicycle, the frame and forks are perfectly rigid and the shocks and vibrations of road travel are carried directly through the frame and transmitted to the rider. It is the dual purpose of this invention to devise a bicycle which will be easier to ride, its construction being such as to eliminate most of the minor vibrations and many of the major ones, or at least to greatly soften the transmission of such to the rider and further, to provide a bicycle which will appeal to the eye as conforming to present day standards of streamlining effects. In carrying these ideas into practice, I have constructed a bicycle as shown in the accompanying drawings.
