Improvements relating to Bicycles.
I, LUCIEN STEPHEN CRANDALL, of the Village of Parish, County of Oswego,
and State of New York, Gentleman, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
My invention relates to a device for temporarily supporting a velocipede, such as
a safety bicycle, in position while mounting, and has for its object to provide an
effective arrangement which on the movement of the machine shall automatically
recede so as to offer no impediment to progress.
My invention is an improvement upon the arrangement described and claimed in
the Specification of Letters Patent granted to me No. 16915 of 1895, and is
illustrated in the accompanying sheet of explanatory drawings in which
Figure 1 is a front elevation of a machine to which my improved device is
applied, while
Figures 2, 3, 4, and 5 are respectively detail, front, back, and side elevation and
plan on a larger scale.
In carrying my invention into effect as illustrated in the accompanying drawing
I provide a carrying bracket A immediately beneath the axle carrying tube of the
machine, and this carrying bracket I secure in position by forming one end a to
pass around a cross bar or bridge piece transversely connecting the lower horizontal
members or tubes of the frame, and I connect the opposite side of the bracket by
means of a supplementary carrying strip B passing laterally around the axle
carrying tube and around the extremity of the diagonal member of the frame, the
ends of which strips being screwed to the main bracket A. by screws bas
illustrated.
The main plate of the carrying bracket A I turn in to carry a boss or flanges
for receiving the pivotting pin G upon which is mounted the foot lever or treadle C
to which in turn is pivotally secured the angle supports D. The obliquely disposed
side of the carrying bracket is provided with two cam slots E which at their lower
extremity are widely separated and are diverted slightly in an inward direction and
converge gradually to their upper extremity. The supporting angle bars D which
pivot upon the foot lever or treadle frame C as indicated are drawn together under
the action of a spring F which when the extremities of the supporting bars are not
fixed upon the ground in the slightly diverted extremity of the slots, is of sufficient
strength to draw the bars along the inclined slots to their extreme closed and
oblique position indicated in dotted lines in Figures 1 and 4. The inwardly
diverted lower extremity of the inclined slots secure the angle supporting bars in
their vertical position under the action of the spring F, and the bars only require
a slight movement of the machine to cause their withdrawal therefrom.
It will be seen that the treadle of the foot lever is laterally disposed upon the
left hand of the machine.
When it is desired to mount the machine the treadle of the foot lever is placed
into its horizontal position as indicated in Figure 1 and the angle bars D) are
thereby caused to extend and to stand vertically upon the ground and support the
machine. The left foot is placed upon the treadle C and the saddle mounted.
The pedal upou the right side is now operated and the left foot is withdrawn from
the treadle C whereupon the bars D under the action of their controlling springs
are brought to their inclined and closed position.

page_text: Having now particularly described and ascertained the nature, of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is-
1. The combination with a bicycle frame of a clip or bracket secured thereunder
having cam slots therein gradually converging towards their upper or hinder
extremities and having each of their opposite extremities somewhat slightly
diverted inwardly substantially as and for the purpose hereinbefore described.
2. The combination with a bicycle frame of the arrangement of parts
substantially as and for the purpose herein before described.
Dated this 19th day of September 1896.
