page_text: I, WALTHER WEGMAN-BOSSERT, of 78, Albisriederstrasse, Zurich, Switzerland,
Mechanician, do hereby declare the nature of this invention to be as follows:
This invention relates to an arrangement, applicable to any bicycle, whereby
the latter can be supported or held in the vertical position, when at rest, so as to
facilitate the mounting and dismounting of the machine by the rider and also
to enable learners to master the bicycle more easily.
The arrangement comprises supporting arms which are operated, in their up
and down movements, by the simple manipulation of a pliable bar within a guide
tube, and, for the purpose of pressing the said supporting arms against the
ground, by the simple rotation of a screw.
At
The apparatus possesses two supporting arms which are jointed at their upper
ends to a double shield by means of screws which pass through the latter.
the upper end of this shield are secured the lower ends of two vertical supporting
tubes; these tubes are sectioned and jointed at a certain point in their length so
that they can be folded or bent over as hereinafter set forth.
These supporting tubes are guided, in their vertical movements, by a tubular
fork and by means of sockets, provided with catches, one of which is fixed to the
upper tube of the frame of the velocipede and the other, vertically below the
first, to the tube which connects the bottom bracket to the steering pillar tube
of the cycle.
-
A plate carrying a screwed socket or box-nut and having semi-circular and
downwardly curved ends is screwed to the upper socket aforesaid of the frame;
above this plate a curved plate is arranged to which the upper ends of the afore-
said supporting tubes are riveted. Passing freely through this latter plate, at
its centre, is a rod, with flattened sides, having screw threads cut on it and which
is capable of being screwed into the aforesaid screwed socket or box-nut. Above
the upper plate the screwed rod just mentioned has a lever keyed to it by means
of which it can be turned so as to give the screw a rotary motion.
Below the bottom bracket a frame is fitted having two grooves in it arranged
at an angle to one another. In these grooves two slides can glide which slides
are joined to crossed bars whose front ends are jointed to the supporting arms.
When the supporting tubes are lowered the inclined grooves of the bottom
bracket frame force the slides, during their descent of the grooves, a certain dis-
tance apart and as a result the supporting arms, which come to rest on the
ground, are also forced a distance apart so as to keep the velocipede in a state
of equilibrium. When the supporting arms are in the lowered position the afore-
said flat screw is introduced into the screwed socket of the plate affixed to the
upper tube of the frame of the velocipede and by giving the aforementioned
lever a quarter turn the flat screw is caused to engage the screw threads of the
socket thereby securely holding the tubes and the supporting arms in position
as to pron un the velocinede.

page_text: Whenever it is desired to raise the supporting arms, in order to continue the
ride, they are pulled up by means of the lever attached to the upper part of the
apparatus, and, at the same time, the arms, guided by the crossed rods and the
inclined grooves, are caused to move in close together. The upper parts of the
two supporting tubes, when raised up to the proper height, have their joints
just above the upper plate of the apparatus so that the said upper parts of the
tubes can be folded over or lowered down upon the top tube of the frame of the
bicycle..

I, WALTHER WEGMAN-BOSSERT, of 78, Albisriederstrasse, Zurich, Switzerland,
Mechanician, 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 an arrangement, applicable to any bicycle, whereby
the latter can be supported or held in the vertical position, when at rest, so as to
facilitate the mounting and dismounting of the machine by the rider and also
to enable learners to master the bicycle more easily. A further feature of the inven-
tion is that it permits of the rider remaining in the saddle and making free use
of his arms when the machine is stopped.
The arrangement comprises supporting arms which, in contradistinction to a
few improved apparatuses, are not worked by cords, levers with hinges, etc., but
are separated in their up and down movements, by the simple manipulation
of a pliable bar within a guide tube, and, for the purpose of pressing the said
supporting arms against the ground, by the simple rotation of a screw. By
giving the screw a quarter of a turn to the left or to the right the supporting
arms are either pressed on the ground or raised from it.
In order that my said invention may be properly understood I have hereunto
appended four explanatory sheets of drawings which show, by way of example,
one method of carrying the invention into effect or practice.
On the drawings:-
Fig. 1 is a side view of a safety bicycle with the improved apparatus fitted
thereto and shown in the lowered position.
Fig. 2 is a similar view showing the apparatus in the raised position.
Fig. 3 is a front view of the apparatus alone, shown in the lowered position.'
Fig. 4 is a similar view showing the apparatus in the raised position.
Fig. 5 is a plan view showing the supporting arms in the closed position and
also the crossed struts or bars in the closed position.
Fig. 6 is a front view of the supporting tubes.
Fig. 7 shows the tubular fork which acts as a guide to the supporting tubes.
Fig. 8 shows the guide for the struts.
Fig. 9 is a side view, to an enlarged scale, of the upper parts of the apparatus.
Fig. 10 is a front view of the parts shown at Fig. 9.
Fig. 11 shows in plan and side view, to an enlarged scale, the foot m of the
apparatus.
Fig. 12 shows in side view and sectional plan to an enlarged scale, the
bracket n.

page_text: Fig. 14 is a plan view of the curved plate g.
Fig. 15 shows the flat sided screw y.
On the drawings the same reference letters wherever repeated indicate the
same parts.
A A indicate the supporting arms which are suspended from the double shield
sch by means of screws z which pass through the latter. Two lengthened
toothed heads a lock into each other and are so arranged as to prevent the bicycle
swaying or rocking when the supporting arms are in operation. indicates the
supporting tubes to the lower ends of which the shields ch is attached. These
tubes which are in sections, b, c, are suitably jointed together in order to allow
of them being raised into the upper or raised position and folded as shown at
Fig. 2. The upper tubes work in the tubular fork d which serves as a guide for
same. Care sockets to which the fork d, d, is secured and which are provided
with two jaws e. f is a bridle carrying a box nut or screw socket f' and provided
with semi-circular edges bent downwards, and which is screwed to the sockets C..
g is a bent plate to which the supporting tubes b, c, are rivetted. h is a fixed
lever provided with a head, etc., and which is screwed on to the pear shaped
head . y is a flat sided screw whose upper end enters a tapped hole in the
head whilst it can freely turn in the plate g.
When it is intended to make use of the apparatus the folded down parts c
are raised into the vertical position and pushed down into the fork d, d. This
movement causes the screw y to enter the socket-nut f¹ of the bridle f and as the
thread of this screw is very coarse a quarter of a turn given to the lever h is
sufficient to force the arms A A down on to the ground. The arms are simul-
taneously separated by the action of the struts 1, 1, and guide as will be
hereinafter more fully set forth. By so forcing down the arms A the machine
can be very expediously stopped.
The headrests freely on the plate g.
k and are two rings with pivots, one of which is rivetted on the supporting
arms A a little higher up than the other. 1, are two struts, one end of each
of which turns on its pivot k whilst the opposite end is freely screwed to the
foot m, the toothed head of which enters automatically the rack attached to the
bracket n. When the arms A are brought together, the foot m disengages itself
from the rack n' (see Fig. 2). The bracket n is provided with the rack n³, a
bolt o and a bolt 9 and is screwed to the under side of the bottom bracket of the
cycle frame. is a triangular guide plate or frame secured to the bolt o and
provided with two slots at an angle to one another (see Figs. 3 and 8) in which
the struts or cross bars 1, 11, are guided. Owing to this triangular guide plate
the arms A can be automatically opened and closed simply by the raising and
lowering of the device as before mentioned. As will be seen when the arms A
are raised the struts 1, 11, are caused to move upwards in the inclined slots p
of the guide (see Fig. 8) with the result that they are brought close together;
likewise, when the arms A are forced down, the movement of the struts simul-
taneously forces them apart.
The bolt of the bracket n is surrounded by a spiral springs which acts upon
the foot m in such a manner as to force it into engagement with the rack n¹
when the device is lowered. t is a nut against which the spring
s bears.
u, w, are swivelling castors provided with rollers and secured to the lower
ends of the arms A. Each castor consists of an upper part (w) and a lower
part (u) and the upper part, which constitutes a box, is fixed to the arm A
whilst the lower part can turn within the upper part being held in position by
a bolt q¹ screwed into the end of the supporting arm A. The part u is provided
with a hollow socket or box a within which balls are arranged said balls being
held pressed against the bottom of the box by means of a spring s¹ wound round
the bolt q. The spring gives a cushioning action to the part u so as to com-
pensate for inequalities on the road over which the machine is driven.

page_text: The sockets C, C, of the fork d, d, can be secured to the top tube of the bicycle
by means of the jaws e which can be made to embrace the tube and be then
clamped in place by screws 2¹. Likewise the guide collars C, C', for the tubes b,
can be fastened to the lower frame tube (see Figs. 1 and 2) by means of jaws e¹
and screws z¹.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
consider novel and desire to claim is:-
A bicycle support capable of being raised and lowered and having curved
supporting arms which automatically open and close, characterized by castors
at the ends of the supporting arms said castors having a spring action in order
to counteract the inequalities of the road; by supporting arms freely suspended
from a double shield s ch appropriately fixed to parallel tubes b jointed to tubes c
and guided in a fork d, the tubes c being connected to a plate g
provided with a lever and screw y which latter can enter a screwed
socket on the bridle f; and by the arms being automatically opened
and closed by the action of struts 1, 1, (provided with a foot m acted on
by a springs and whose toothed end engages a rack on the bracket a) working
in a triangular guide attached to the bottom bracket, substantially as herein-
before described with reference to the drawings annexed.
