Improved Supports for Bicycles.
I CARL SIPMAN of 49 St. Mary Gate in the Town and County Town of
Nottingham, Silk Merchant do hereby declare the nature of this invention to be
as follows:-
The object of this invention is to provide bicycles with an attachment, working
automatically, which will enable the machine at a momentary stoppage or when not
in use to stand erect without support.
According to my invention I employ a plate to be attached to one of the bars or
tubular rods, forming the frame of a bicycle to which plate are fixed two legs by
binges so arranged that when the bicycle is in use the legs are raised up and lie parallel
to each other in front of the bar, but when released the legs, acted upon by a spring
and their own weight, they open out automatically at any angle arranged for and
touching the ground enable the bicycle when not in use to stand erect without
support.
When the bicycle is to be put in motion the legs are drawn up by a string and
assume their original position in front of the frame bar. By this invention the
rider of a bicycle is enabled to leave his machine at any moment without the
necessity of laying it on the ground or supporting it.

I CARL SIPMAN of 49 St. Mary Gate in the Town and County Town of
Nottingham, Silk Merchant, 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 :-
The object of this invention is to provide bicycles with an attachment with
moveable legs closing and opening automatically which will enable the bicycle
at a temporary stoppage or when not in use to stand erect without any further
support.
According to my invention I employ a plate or casting fixed by screws or a rim
to one of the bars or tubular rods forming the bicycle frame. The legs are hinged
to the plate or casting at an inverted angle as shown in Fig. I so arranged that
when the legs are not in use they point upwards and lie parallel and close to each
other below the frame bar, in which position they are retained by a catch or spring.
When the legs are let down they open out automatically and in their downward
position, resting against the slanting part of the casting afford a support, which
enables the bicycle to stand erect. Springs are fixed to the casting to keep the
legs in their respective positions.
As the legs between their upward and downward position form an angle of
135 degrees (more or less according to the shape of the bicycle frame) I hinge the

page_text: legs on a plane cut at two inverted angles as shown in the accompanying drawing
Fig. I, m. n. o. being the plane and o. m. o. and o. n. o. the two angles at which the
plane has been cut.
The accompanying drawings show how the invention is carried out, but I do not
confine myself to the precise details shown in the illustrations, as the details may
be varied to suit the different shapes of bicycle frames.
Fig. 1. shows in which way the planes m. n. o. to which the legs D. D. are
hinged, are cut at two inverted angles o. m. o. and o. n. o. so as to enable the
legs D. D. to lie parallel and close to each other below the bicycle bar when in
their upward position and to open out automatically when assuming their downward
position.
B. indicates the position of the rim by which the mechanism is fixed to the bicycle
frame.
C. is the centre part of the casting as shown in Fig. III.
D.D. are the legs hinged on the plane m. n. o, one leg is shown in its upward
and the other leg in its downward position.
Fig. I is a side view and Fig. I'll a front view of the mechanism fixed to the
bicycle frame by a rim B. But instead by a rim the mechanism may be screwed or
may in any other way he fixed to the bicycle frame.
Fig. II. A A is the frame bar to which the mechanism is fixed by
B. the rim.
C. is the lower part of the casting to which at an inverted angle as previously
described the legs are hinged.
D. D. are the legs, one of them shown in its upward position lieing under
the frame bar A and the other shown in its downward position supporting the
bicycle.
É is the spring, fastened to the back of the casting with its upper arm licing in a
groove cut inside the rim (as shown in Fig. III) keeping the leg in its respective
position.
Fig. III. B B is the rim, by which the mechanism is attached to the bicycle
bar.
C. is the lower part of the casting cut slanting with grooves into which the
legs fit.
D. D. are the legs shown in their downward position opened out and forming a
support to the bicycle.
E. are grooves cut inside the rim into which the springs, acting upon the
legs, fit.
F are the pins by which the legs are hinged at an inverted angle to the casting.
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. The attachment to the frame of a bicycle of a portable mechanism with
"moveable legs, closing and opening automatically.
2. The mode in which the legs are hinged to the casting at inverted angles so as
to lie parallel and close to each other below the bicycle frame bár and opening out
automatically afford in their downward position a support to the bicycle.
3. The employment of springs to hold the legs in their respective position.
