Improvements relating to Supports for Cycles.
I, LUCIEN STEPHEN CRANDALL, of 62 Moor Street, in the City of Birmingham,
Engineer, 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:-
This invention consists of improvements relating to cycles, my objects being to
provide in combination with a cycle support or rest, simple and effective means
whereby the said support or rest shall be brought into its service position when
necessary, by the act of back pedalling; and to affix such rest to an integral part
of the cycle framing in a secure and convenient manner without the use of
clamping or like fastening devices.
In order that my invention may be more readily understood, I append hereunto
two accompanying sheets of explanatory drawings to be hereinafter referred to:
Figure 1, on Sheet 1, is an elevation representing in outline a portion of a
bicycle having a brake and rest in conjunction with mechanism arranged in
accordance with my invention.
On Sheet 2, Figure 2 is an end elevation and Figure 3 a side elevation
representing my rest operating device to a larger scale.
The same reference letters in the different views indicate the same parts.
The brake A illustrated at Figure 1 is arranged for operation by back pedalling
preferably in the manner described in my Specification No. 14542 of 1897. Upon
the crank axle B I form or attach the cam collar or boss C, and on the rest or
support D, jointed to the lower end of the tube E, which is formed with or rigidly
attached to the bottom bracket E' of the cycle frame, I pivot the pawl link or
rod F whose upper end is maintained by a suitable spring in contact with the
periphery of the cam collar or boss C.
When the axle B revolves in the ordinary or forward direction, indicated by
the arrow in Figures 1 and 3, the cam or projection from the face of the collar or
boss C presses out the upper end of the pawl link or rod F at each revolution and
thus passes the same without imparting any movement to the rest or support D.
But when the rider back pedals" and so causes the axle B to revolve in the
reverse direction, the cam or projection of the collar or boss C will abut against
the upper extremity of the pawl link rod F, and on such abutment the further
movement of the cam will force the pivotted rest D from its out of service position,
indicated by dotted lines at Figures and 3, into the position, indicated by the
full lines for supporting the machine when not in motion, in its upright position.
The rest is maintained both in its service and out of service positions, and
prevented from accidental movement therefrom preferably by a double action
spring G disposed within the tube E in conjunction with an internal projection
from the rest D.
The collar or boss C is so disposed on the shaft B in conjunction with a similar
cam boss operating the brake A, that the rest D is only brought into its service
position simultaneously with the complete arrest of the motion of the machine
~ the notion of the brake

page_text: I employ my invention with both the brake operating and gear changing
mechanism described in my Specification No. 14542 of 1897 or with such brake
mechanism alone. I also adapt my bicycle rest operating device in conjunction
with brakes of types other than that hereinbefore referred fo.
:
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. In combination with a cycle support or rest, means whereby such support or
rest is brought into its service position by the act of back pedalling, substantially
as described.
2. The combination on a cycle of a brake and a support or rest with means
whereby the support or rest is brought into its service position simultaneously
with the complete arrest of the machine by the action of the brake substantially
as described.
3. The affixing of a cycle support or rest with an internal part of the cycle 1
framing substantially as described.
4. The improved general arrangement of parts in combination with a cycle
rest or support substantially as and for the purposes described and as illustrated.
