PROVISIONAL SPECIFICATION.
A New or Improved Bicycle Attachment or Construction for Use of
Learners.
I, WILLIAM ATTON of 4 Grosvenor Square, London, W., Valet do hereby
declare the nature of this invention to be as follows:-
The purpose of this invention is to provide an attachment to be fitted to or fixed
upon the frame of a
bicycle to serve for the supporting of the latter when ridden.
by a learner or other person unacquainted with the art of bicycle riding.
This attachment is made with two arms or frame bars connected together and
adapted to be fixed to a suitable part of the bicycle for instance at or near the
saddle pillar so that the said bars extend downwards towards the ground one on
each side at a suitable distance from the driving wheel. These two bars terminate
in suitable guides in which are vertically adjustable rods or the like carrying forks
in which are journalled small wheels. The aforesaid bars may be suitably stayed
for instance by two struts connecting them to the driving wheel forks of the rear
driven safety bicycle, or in any other appropriate manner for other types of
bicycle.
For beginners the wheels may be adjusted to touch the ground, and as the
learner progresses in the art they may be adjusted to clear the ground slightly
when the bicycle is balanced and moving in a straight line, they may then be
raised further as the learner becomes efficient.
Where the bicycle is employed solely for teaching purposes the above parts may
be made a fixture and part of the frame work, but for ordinary teaching they may
be made with suitable sockets to fit any bicycle.

A New or Improved Bicycle Attachment or Construction for Use of
Learners.
I, WILLIAM ATTON, of 4 Grosvenor Square, London, W., Valet, 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 purpose of this invention is to provide an attachment to be fitted to or fixed
upon the frame of a bicycle to serve for the supporting of the latter when ridden
by a learner or other person unacquainted with the art of bicycle riding.
This attachment is made with two arms or frame bars adapted to be connected
together and fixed to a suitable part of the bicycle for instance at or near the
saddle pillar so that the said bars extend downwards towards the ground one on
each side at a suitable distance from the driving wheel. These two bars terminate

page_text: in suitable guides in which are vertically adjustable bars or the like carrying forks
or hangers in which are journalled small wheels. The aforesaid bars may be
suitably stayed, for instance by two struts connecting them to the lower tubes of
the driving wheel forks of the rear-driven safety bicycle, or in any other appropriate
manner for other types of bicycle.
For beginners the wheels may be adjusted to touch the ground, and as the
learner progresses in the art they may be adjusted to clear the ground slightly
when the bicycle is balanced and moving in a straight line, they may then be
raised further as the learner becomes efficient.
Where the bicycle is employed solely for teaching purposes the above parts may
be made a fixture and part of the framework, but for ordinary teaching they may
be made with suitable sockets or attachments to fit any bicycle.
The annexed drawings show the attachment as affixed to a rear-driving safety
bicycle, the latter being indicated in dotted lines. Fig. 1 is a sule elevation;
Fig. 2 is a plan; Fig. 3 is an end elevation and Figs. 4 and 5 are detail views of
parts on a larger scale.
A, A, are two tubes secured in the sockets at the end of the bar B or otherwise
connected together. This bat B is made to fit over or to the two back tubes c, c,
of the frame of the bicycle and is secured by the bar D made to fit over or to the
seat pillar tube d of the frame; the bars B and D being secured together by
screw-bolts or the like E. F, F, are two brace frames which may be connected to
the tubes A, A, or to sockets thereon as to be capable of swinging in order that
they may be adjusted to the tubes f of the bicycle frame whatever may be the
angle of the tubes towards one another and towards the ground. The brace
frames F, F, are connected to the tubes f, f, by sockets formed each of two halves
connected by screws or bolts and nuts. The tubes A, A, terminate below in
vertical sockets G, G, each of which is formed of two flanged parts one of which
is rigid with the tube and the other part fixed to the rigid part by bolts and nuts
or by screws. In these sockets slide the bars H having at their lower ends
horizontally projecting studs J on which the wheels K revolve. The bars H are
vertically adjustable in the sockets G and may be fixed at the desired height by
set-screws L. It is preferable to line with felt or the like the sockets by which
this appliance is fitted to the bicycle frame so that the surface of the latter may
not be injured.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is ;-
The bicycle attachment constructed substantially as described and carrying two
wheels, one on each side of the bicycle, adapted to be adjusted and fixed in contact
with or at a suitable distance from the ground for the purpose specified.
Dated this 31st day of December 1895.
