Improvements in Stands or Rests for Attachment to Bicycles.
We, THE AUTOMATIC CYCLE STAND LIMITED (a Joint Stock Company duly
incorporated under the laws of Great Britain and Ireland) of 5 Fell Street, Wood
Street, London, and JAMES JOHN SHEDLOCK also of 5, Fell Street aforesaid Engineer,
do hereby declare the nature of this-invention-to be as follows:-
This invention relates to stands or rests for attachment to bicycles such that while
said stand or rest will be carried on the bicycle clear of the ground it will be ready
and in convenient position for use immediately the rider stops and wants to leave the
machine standing alone or at any moment when it is desired to leave the machine
but retain it in an upright position independently of any separate stand or support
and the present invention consists of certain improvements or modifications on a
stand or rest for bicycles of the character for which T. F. and S. E. Spencer
obtained the grant of Letters Patent dated 28th June 1894 No. 12558.
The present invention is as follows:-
A suitable clip or clips or other suitable means for attaching the appliance to the
bicycle is or are cast or otherwise suitably formed or mounted to a curved plate or
hollow block or device advantageously in the form of a hollow sector covered in on
all sides or in any suitable manner so as to exclude dust and dirt from the interior
thereof as much as possible.
On this curved plate or device there may or may not be also provided two laterally
extending bent arms-the bent over ends of which are adapted to rest on or fit over
the back fork of the machine and being of suitable spring steel or other suitable
material will consequently readily fit on forks of different dimensions.
Within this curved plate or aforesaid device in or on the concave side thereof
two grooves or channels are formed or mounted in a direction other than parallel to
one another that is these said grooves or channels are at an inclination to one another
and the upper end of each of the two legs of the stand or rest are so mounted and
held as to operate in said channels or grooves which latter consequently control said
legs as hereinafter explained.
Each leg is formed either all in one piece or in two or more sections either of
metal or wood or both or other suitable material for instance the upper part of each
leg may be cast solid near the top part thereof and tubular for the remaining part
forming a socket in or to which a wooden or other suitable lower part may be
mounted or secured in any suitable manner.
This upper part of each leg has a pin or axle passed through same or same may
pass through the pin or axle on which it turns said pin or axle being journȧlled or
otherwise suitably mounted in the side cheeks of said curved plate in any suitable
manner but so that the requisite amount of lateral movement of said legs can take
place for instance a square pin or axle may be passed through a hole of corresponding
size in the upper part of each said leg each said hole however being sufficiently
enlarged in one direction to permit the lateral play aforesaid the upper part of said
legs being kept a sufficient distance apart in any suitable manner for instance by
a pin passing right through same and the axle to which they are thus pivoted or
joined.
Any suitable spring or springs is or are mounted in any suitable manner in
connection with said legs so as to normally keep said legs pressed firmly in one

page_text: direction and this is advantageously effected by a coiled spring one end of which is
fixed to the axle between the two legs and the other end of said spring fixed to
some part of the aforesaid curved plate or to the casing thereof; or instead of a
coiled spring a flat or curved spring may bear against a pin or projection on the
axle so that when the said legs are swung round through part of a circle and
thereby correspondingly rotate the aforesaid axle consequently the said spring will
be wound up or caused to exert pressure against such movement of the legs and
therefore immediately return said legs-when released-to their normal position.
The curve of the inside of the aforesaid curved plate or device is such that same is-
or is formed or mounted-otherwise than concentric to the centre of the pin or axle
on which the legs are respectively pivoted or mounted as aforesaid so that when the
said legs have been swung round into position for supporting the bicycle the top end
of each said leg will (at such point only) press or just touch against the inside of said
curved plate while said leg ends will pass clear of or without touching same at any
other point-thus affording direct support when the weight is on said legs and obviating
unnecessary friction while the legs are being swung or moved round as aforesaid.
The top end of each said leg nevertheless always remains in and controlled by
the aforesaid diverging grooves or channels during the whole of its movement in
either direction so that when said legs are swung downwards the side walls of said
grooves will cause the top ends of the legs to converge and consequently the lower
ends of said legs to diverge or expand and vice versa as the spring returns said legs
to their normal position when out of use.
Instead of constructing these stands separately from the bicycle and attaching
same to the machine by clips or other suitable means as aforesaid the aforesaid
curved plate and guide channels or grooves may be formed or mounted integrally with
or on or permanently mounted on any suitable part of the machine advantageously on
or near the bottom bracket or on the backbone or frame near same and the legs
suitably mounted so as to operate as herein before described but this last-named
construction would of course be more suitable when building new machines.

We, THE AUTOMATIC CYCLE STAND LIMITED (a Joint Stock Company duly
incorporated under the laws of Great Britain and Ireland) of 5, Fell Street, Wood
Street, London, and JAMES JOHN SHEDLOCK also of 5, Fell Street aforesaid, 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 relates to stands or rests for attachment to bicycles such that while
said stand or rest will be carried on the bicycle clear of the ground it will be ready
and in convenient position for use immediately the rider stops and wants to leave
the machine standing alone or at any moment when it is desired to leave the
machine but retain it in an upright position independently of any separate stand or
support and the present invention consists of certain improvements or modifications
on a stand or rest for bicycles of the character for which T. F. and S. E. Spencer
obtained the grant of Letters Patent dated 28th June, 1894, No. 12558.
And in order that the present invention may be fully understood and readily

page_text: carried into practice we will proceed to describe same with reference to the drawings
hereunto annexed.
Fig. 1 is a side elevation of our improved stand or rest attached to the bicycle
and in position supporting same.
Fig. 2 is the position it automatically assumes and retains directly the bicycle
is moved forward or the legs otherwise freed from the ground.
Fig. 3 is a vertical section showing the internal construction of the appliance-
removed from the bicycle.
Fig. 4 is plan of the underside of the device-i.e. looking in the direction of
the arrow y Fig. 3.
Fig. 5 is end view of the appliance-looking in the direction of the arrow
Fig. 4.
Fig. 6 is similar view to Fig. 4 with the legs and spring removed in order to
show details of construction.
Similar letters of reference indicate corresponding parts throughout.
a is the clip or attachment by which the appliance is secured on or to the part a¹
or any other suitable part of the bicycle-or any other suitable means for clamping
or attaching the appliance in position may be used if desired.
b is curved plate or device having side plates or cheeks thereon and also this
curved plate 6 on the underside has two converging guideways or channels forming
what we term "cam-ways" c see Figs. 3 to 6-the side walls c¹ of said cam-
ways e acting on the inner end d' of each pivoted leg d as cam surfaces to thus cause
the two said inner ends d¹ to converge or diverge as the case may be and consequently
expand the outer or free end of the legs d or contract same as the case may be-
as hereinafter explained.
The legs d d are pivoted at d* on a pin or axis e which latter is journalled or
securely mounted in or to the aforesaid side cheeks 6' 62 and the said pin or axis e
is securely attached to the inner end of a coiled spring while the other end f¹
of such spring is fixed to the curved plate or device b (or any other suitable spring
may be used and one end thereof attached to the axle and the other end to some fixed
part of or on the device b) in such manner that said spring will through the said
pin or axis e normally keep said legs d firmly pressed in the opposite direction to the
arrow (Fig. 3) the inner ends d' of said legs coming to rest against suitable
stops consequently when the legs d d are moved round (in the direction of the
arrow) into the position shown in dotted lines in Fig. 3 thereby the already
wound spring is further wound and exerts a strong tendency to force back said
legs d immediately same are released.
Thus it will be seen that when the legs d are forced from the position shown in
full lines to the position shown in dotted lines in Fig. 3 thereby the inner ends d' are
forced by the camway e to converge and consequently the outer end of the legs d
are forced apart to form a wide base for holding up the bicycle while on their release
the spring will instantly force said legs back into their normal position as before
explained.
The movement of the inner ends d' of said legs is limited by the said stops g at
each end of each camway c or other suitable stops may be used if desired.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. A stand or rest for attachment to bicycles having the legs pivoted to a pin or
axis and the latter journalled in the side cheeks of-and concentric with the curvature
of a curved plate or device provided with converging guideways or camways
on the concave face thereof in such manner that the inner ends of said legs are
respectively guided in said camways and thereby the outer ends of the latter are
caused to diverge when said legs are swung in one direction against the action of a
spring provided to return said legs to their normal position again when released and

page_text: thereby through the aforesaid camway cause the outer ends of the legs to again
converge substantially in the manner and for the purposes hereinbefore described.
2. A stand or rest for attachment to bicycles consisting of a curved plate or device
such as having converging guideways or camways such as c on the concave face
thereof and side cheeks or flanges such as 662 thereon, a pin or axis such as e
journalled in the latter concentric with the curvature of said device blogs pivoted
to said pin or axle e the inner end of which legs operate in said camways c, a spring
such as fixed at one end to said pin or axis e and at the other end to said device b
and means to limit the movement of the legs d by limiting the travel of the inner
ends thereof within said camways call substantially in the manner and for the
purposes hereinbefore described and illustrated in the drawings hereunto annexed.
3. A stand or rest to be carried on a bicycle arranged constructed combined and
, acting substantially in the manner and for the purposes hereinbefore described and
illustrated in the drawings hereunto annexed.
