Abstract
Abstract The present invention relates to devices for connecting two bicycles in parallel side-by-side relation to permit simultaneous operation by the party seated on either of the bicycles, and comprises a plurality of elements ensuring simultaneous steering of the front wheels of both bicycles by the rider on only one bicycle, as well as means to render the handle bars of one of the bicycles immobile for the purpose of steering together with spacing connecting elements connecting the two bicycles at an intermediate point of their length and at the rear wheel axles. The intermediate and rear axle connecting elements are adjustable to permit tightening or loosening of the chains of the bicycles.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
120 words
Apparatus for connecting two bicycles for simultaneous operation in spaced side-by-side relation including: a spacing bar connected to the front ends of the frames of two bicycles, means associated with the handle bars of the bicycles to provide uniform steering of the bicycles by the rider of one of the bicycles, means carried by said bracing bar for rendering the handle bars of one of the bicycles immobile for steering operation whereby the two bicycles may be steered only by the rider of the bicycle whose handle bars are not immobilized, a rigid bracing element connecting the two bicycles intermediate their front and rear portions and a third rigid connecting and spacing element connecting the rear axles of the bicycles.
Claim 2
Dependent Claim
120 words
Apparatus for connecting two bicycles for simultaneous operation in spaced side-by-side relation including: a spacing bar connected to the front ends of the frames of two bicycles, means associated with the handle bars of the bicycles to provide uniform steering of the bicycles by the rider of one of the bicycles, means carried by said bracing bar for rendering the handle bars of one of the bicycles immobile for steering operation whereby the two bicycles may be steered only by the rider of the bicycle whose handle bars are not immobilized, a rigid bracing element connecting the two bicycles intermediate their front and rear portions and a third rigid connecting and spacing element connecting the rear axles of the bicycles.
Claim 3
Dependent Claim
79 words
Apparatus for connecting two bicycles as claimed in claim 1, including releasable means connecting the intermediate bracing element to the bicycles to permit limited rotary movement of the intermediate bracing element, means connecting the intermediate bracing element to the rear axle connecting and bracing element so that when the rear axle and bracing element is moved the intermediate bracing element will be slightly rotated to permit uniform adjustment of the chains of the two bicycles in exact unitary degree.
Claim 4
Dependent Claim
37 words
Apparatus for connecting two bicycles as claimed in claim 1, wherein said handle bar immobilizing means comprises a plate carried by said bracing bar and having one end engaging the handle bars of one of the bicycles.
Claim 5
Dependent Claim
94 words
Apparatus for connecting two bicycles as claimed in claim 1, wherein said means for providing uniform steering of the bicycles includes plates carried by and extending forwardly from the front wheel fork structures of the bicycles, a pair of adjusting screws carried by each plate to provide minute adjustment of the angles of the plates to the front forks of the bicycles, pins carried by the plates and a bar having its ends mounted on the pins and connecting the two plates to ensure uniform steering movement of the front wheels of the bicycles.
Claim 6
Dependent Claim
20 words
Apparatus for connecting two bicycles as claimed in claim 4, including means for simultaneously adjusting the chains of both bicycles.
Claim 7
Dependent Claim
21 words
Apparatus for connecting two bicycles as claimed in claim 1, and including means for simultaneously adjusting the chains of both bicycles.
