PROVISIONAL SPECIFICATION.
Improvements in or applicable to Bicycle Stands.
I, JOSEPH JULIUS MÜLLER, of 5 Raadhusstraede, Copenhagen, in the Kingdom
of Denmark, Joiner, do hereby declare the nature of this invention to be us
follows:-
This invention relates to a bicycle stand which also serves to enable a bicycle to
be used as a home-trainer. When used simply as a stand to support the driving
wheel, it offers a considerable advantage in that the driving wheel may without
difficulty be cleaned and examined, since the wheels can be rotated freely. The
driving wheel is so supported at the crank bearings that both wheels are raised from
the ground. The frame is formed of two plates to which the form of feet is given
at their lower ends and which are held together by three cross bolts. On the side
of the upper part of each of the foot-plates a second plate is so arranged as to be
vertically adjustable and secured in place by a clamping nut, the screw bolt of
which is secured to the foot plate and passes through a vertical slot in the second
plate. The necessary guides for the movement of the second plate upon the foot
plate may be formed by turning the edges of the former over those of the latter.
The upper end of the second plate forms a V-shaped bearing for the bearing of
the pin of the crank axle.
The cross bolts are firmly secured to one of the foot plates whilst they are
connected to the other by means of a nut on either side of the latter. It is thereby
rendered possible to vary the distance between the foot plates according to the
length of the bearing of the pin of the crank axle. The arrangement by which the
second plate is made to slide upon the foot plate also renders it possible to vary
the height of the stand according to that of the bicycle.
The driving wheel is held fast by means of a hook which embraces the crank
bearing above. The hook is screwed into a slotted block which slides upon a plate
which is fastened to the uppermost of the cross bolts. This plate carries a bolt
which passes through the slot in the block which is clamped by means of a wing
nut. If the wing nut is screwed home, the block and with it the hook is drawn
downwards so that the driving wheel is firmly pressed against the support. If the
driving wheel is not to be used for home training the front wheel is supported by
an arm which is secured to one of the cross bolts and is made with a fork at its
upper end. The arm consists of two parts of which one is constructed as a tube
and embraces the other, so that the length of the arm may be varied. A screw
holds the two portions firmly in the proper position. If the driving wheel is to be
used for home training, the said arm is removed whilst the hind wheel or driving
wheel is made to rest upon the home trainer. The latter consists of two rollers
which revolve with a suitable amount of resistance. The surface of the rollers is
made concave, in order to afford a secure support to the tyre of the driving wheel.
The front wheel is placed in a wooden shoe and supported by spiral springs which
are booked round the axle bearing.

I, JOSEPH JULIUS MÜLLER, of 5, Raadhusstraede, Copenhagen, in the Kingdom
of Denmark, Joiner, 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 a bicycle stand which also serves to enable a bicycle to
be used as a home-trainer.
In the accompanying drawing;
Figure 1 is a perspective view shewing a bicycle stand constructed according to
my invention applied to a bicycle for simply supporting the same in an upright
position; and,
Figure 2 is a similar view shewing the stand as applied when requiring to use
the bicycle as a home-trainer.
When the stand is used simply to support the bicycle, as shewn in Figure 1, it
offers a considerable advantage in that the bicycle may without difficulty be cleaned
and examined, since the wheels can be rotated freely. The bicycle is so supported
at the crank bearings that both wheels are raised from the ground. The frame is
formed of two plates a to which the form of feet is given at their lower ends and
which are held together by three cross bolts b. On the side of the upper part of
each of the plates a a second plate c is so arranged as to be vertically adjustable
and secured in place by a clamping nut c', the screw-bolt of which is secured to the
plate a and passes through a vertical slot in the plate c. The necessary guides for
the movement of the plates c upon the plates a may be formed by turning the edges
of the former over those of the latter. The upper ends of the plates c form
V-shaped holders for receiving the bearings of the crank axle.
The cross bolts are firmly secured to one of the plates a whilst they are
connected to the other plate by means of a nut on either side of the latter. It is
thereby rendered possible to vary the distance between the plates a according to
the length of the bearings of the crank axle. The arrangement by which the
plates c are made to slide upon the plates a also renders it possible to vary the
height of the stand according to that of the bicycle.
The bicycle is held fast by means of a hook which embraces the crank bearing
above. The hook is screwed into a slotted block e which slides upon a plate f
which is fastened to the uppermost of the cross bolts b. The plate carries a bolt
which passes through the slot in the block e which is clamped by means of a wing
mut g.
If the wing nut g is screwed home, the block e, and with it the hook d, is
drawn downwards so that the bearing of the crank axle is firmly pressed against the
support. If the bicycle is not to be used for home training the front wheel is
supported by an arm which is secured to one of the cross bolts b and is made with a
fork at its upper end. The arm consists of two parts and 2 of which one is
constructed as a tube and embraces the other so that the length of the arm may be
varied. A screw i holds the two portions firmly in the proper position.
If the bicycle is to be used for home training, as illustrated in Figure 2 it is
lifted onto the stand in the usual manner, but the arm h', h which supports
the fore wheel is removed, supporting springs are screwed into the floor and
hooks thereon are passed on to the axle of the front wheel; the home-trainer is
then pushed in beneath the driving wheel, and the hook and nuts are secured in the
stand.
The home-trainer consists of two rollers m, m which revolve with a suitable
amount of resistance. The surface of the rollers is made concave in order to afford
a secure support to the tyre of the driving wheel. The front wheel is placed in a
wooden shoe n. It is not necessary to fasten the home-trainer to the floor.

page_text: The axle bearings for the rollers are covered with felt whereby a considerable
amount of friction is obtained dependent on the weight resting on the rollers. This
weight and therefore the resistance of the rollers can be varied by tightening or
loosening the spiral springs or by driving the wedge-shaped shoe n more or less
under the front wheel.
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. A bicycle stand consisting of two plates or feet which are connected by means
of screw-threaded cross-bolts which admit of the regulation of the distance between
the two plates, two vertically adjustable plates attached to the first named plates
and adapted to support the crank axle of the bicycle, a hook serving to keep
the bicycle in position, which hook by means of a slotted block sliding on a plate
and a wing nut can be pressed against the crank-axle; in combination with a home-
trainer consisting of two rollers rotating at suitable distances apart, substantially as
herein before described and illustrated in the accompanying drawing.
2. The improved bicycle stand bereinbefore described and illustrated in the
accompanying drawing.
