PROVISIONAL SPECIFICATION.
An Appliance to be used in connection with the Teaching of Cycle
Riding.
I, AARON SMITH CARTWRIGHT, of 75, Ford Street, Hockley, in the City of
Birmingham, Manufacturer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to an appliance to be used in connection with the teaching
of cycle riding, and consists essentially of an attachable arm or bar secured to the
upper end of the back forks or other convenient part of the machine, and which
stands out and is laid hold of by the person who is instructing and assisting the
learner to ride. By the employment of such an appliance the machine on which
the learner is mounted is kept balanced without any undue exertion or weight
being thrown upon the instructor.
In carrying out one form of my improvements, I take an arm, bar or equivalent,
which preferably has a handle at one end, and I secure to the other end, an attach-
ment which may consist of a fixed and a sliding or movable jaw, adapted to
embrace the back forks of a cycle frame, preferably near to the seat pillar lug,
and with the movable jaw, clip or the like capable of being adjusted by a rotating
screw, cross pin, set pin or by other locking or affixing means.
The handle may
stand out at a right angle or other angle from the machine, so that the instructor,
in holding up and balancing the bicycle, shall be out of the way of the back
wheel, but to this I do not limit myself, as the holding up arm may be disposed in
any convenient position, and if necessary, it may be jointed, so as to admit of the
shaft or handle part taking any angle relative to the machine and may be locked
in its adjusted position by a cross bolt or other means. When claw or like clips
are employed they may be faced inside with cork, felt, leather or other non-
scratching material,
Or the attachment end of the bar may be formed as a band-clip drawn around
the seat tube or seat pillar, or as clips drawn around the back stays or other suit-
able part of the machine framing.
Instead of a single handle I may have two handles mounted on a cross bar or
double bars which would be useful where two instructors are required, such as in
teaching heavy riders. In this case, the attachment part may be arranged to clip
and embrace the upper ends of the seat tube and back stays, so as to give a good
hold upon three members of the framing.
If required, the handle or handles may be arranged to fold up or down so as not
to be in the way of a learner who has become sufficiently proficient to be able to
ride without being supported by the teacher.

I, AARON SMITH CARTWRIGHT, of 75, Ford Street, Hockley, in the City of
Birmingham, Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
1
This invention relates to an appliance to be used in connection with the teach-
ing of cycle riding, and consists essentially of an attachable arm or bar secured
to the upper end of the back forks or other convenient part of the machine, and
provided with an outstanding handle or grip, and which is laid hold of by the
person who is instructing and assisting the learner to ride. By the employment of
such an appliance the machine on which the learner is mounted is kept balanced
without any undue exertion or weight being thrown upon the instructor.
Figure 1 of the accompany drawings represents a back end' elevation fitting
with my attachment for upholding, and facilitating the balancing of a bicycle by
an instructor teaching a person the art of cycle riding.
Figure 2 represents, upon an enlarged scale, the upper part of the back-stays of
a safety bicycle fitted with my said attachment.
Figure 3 is an elevation of the opposite side of the attachment to that shown in
Figure 2, showing the construction of the adjustable clip or clamp by which the
handle or holding part is secured to the frame.
Figure 4 is a side elevation of Figure 2.
Figure 5 is a transverse longitudinal section of Figure 3 upon the dotted line a.
Figure 6 represents an elevation and an edge view of the fixed plate or part of
the securing clamp which is provided with the upholding or steadying handle.
Figure 7 represents an elevation and an edge view of the sliding or adjustable
jaw of the clamp.
Figure 8 represents separate views of the screw pin, clamping nut and washer
by which the two parts of the clamp are secured together and to the machine.
The same letters of reference indicate corresponding parts in Figures 1 to 8 of
the drawings.
a is a flat plate or bar, which has a handle or grip b, at one end, whilst the other
end is formed into a slightly inclined and hook shaped jaw a¹, adapted to partly
embrace one member c', of the back stays c, of a safety bicycle. Mounted upon
the said plate is a sliding or movable and similar-sectioned jaw d¹, adapted to
partially embrace the other back stay member ², of a cycle frame, preferably a
little below the seat pillar lug . The movable jaw or clip carries a fixed pin e,
working in a longitudinal slot 2, made in the plate a, within which the said pin
is capable of being slid when the jaw d¹ is moved along, so as to adjust the grip
of the opposite jaws upon the back stays, after which they are secured or locked by
a washer f, and fly nut g, the latter screwing on the said pin e, or by other locking
or aflixing means. The handle is preferably set at a slight angle relative to the
attachment plate, so that the instructor, in holding up and balancing the bicycle,
shall be able to conveniently hold the same and be also out of the way of the
back wheel, but to this I do not limit myself, as the holding up arm may be
disposed in any convenient position, and if necessary, it may be jointed, so as to
admit of taking any angle relative to the machine as may be most convenient. In
this case the handle would preferably be locked in its adjusted position by a cross
bolt and nut or other means. The claw or like clips employed for gripping the

page_text: members of a machine are lined or faced inside with cork, felt, leather or other
non-scratching material as at a², d, to prevent damage of the enamel.
As a modification, the attachment end of the bar or plate may be provided with
a band-clip adapted to be drawn around the seat tube, seat pillar or other con-
venient member of the machine, or with double and separate clips capable of
respectively embracing the back stays or a like part of the framing.
Figure 9 represents an elevation of another form of my invention in which
instead of a single handle, the attachment is provided with a handle or grip on
each side, and applicable for use in cases where two instructors are required, such
as in teaching heavy riders.
Figure 10 represents the same partly in edge view and partly in transverse
longitudinal section.
In this arrangement the plate a of the attachment is provided with a handle b at
each end, (which handles come one on either side of the machine) and carries a
pair of oppositely directed and adjustable jaw plates a', d¹, which are capable of
sliding over the pins e, up to their gripping positions against the back stay
members c, of the bicycle framing and after which they are locked or made fast
by means of fly nuts g, which take upon the pins, and, when screwed up, tighten
the parts together.
This double-handled attachment may be provided with other forms of clip than
that described, so as to adapt the same for being secured to other parts of a cycle
framing than the back stays as shown in Figures 9 and 10. This attachment
part may be also provided with clamping jaws adapted to clip and embrace both
the upper end of the seat tube and the back stays so as to give a good hold upon
three members of the framing.
If required, the handle or handles may be arranged to fold up or down so as not
to be in the way of a learner who has become sufficiently proficient to be able to
ride without being supported by the teacher.
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:-
First: An upholding or supporting attachment or appliance adapted to be
secured to the framing of a bicycle and to be laid hold of by a person in instructing
or assisting a learner.
Secondly: An upholding or supporting attachment for bicycles, consisting of a
plate, bar or equivalent provided with a handle or grip adapted to be laid hold of
by a person instructing a learner, and having adjustable clamping jaws, clips or
like means for securing the said attachment to a bicycle.
Thirdly: An upholding or supporting attachment for bicycles comprising a
plate or bar fitted with relatively adjustable clamps or clips for securing the
appliance to a bicycle frame and provided with a suitably disposed fixed or
adjustable or hinged handle or grip at one end only or at each end, substantially
as and for the purpose described and set forth.
