A Riding-learner's Safety Attachment for Bicycles.
I, GEORGE TUCKER JONES, 18, Sherwood Place, Llwynypia, in the County of
Glamorgan, Mechanical Engineer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement: —
It consists in attaching to the bottom-bicycle-bracket or the framework pro-
jecting from same, a combination of adjustable tubes or bars, arranged so as to
carry a pair of small wheels in a suitable position to give, in conjunction with
the hind wheel, a triangular wheeling base, immediately-or nearly so, under
the sitting position of the rider.
Clips may be used for connecting this invention on to existing bicycles, and
new bicycles could be provided with convenient projections for receiving the
attachment of same.
This invention is designed chiefly for the use of would-be cyclists who wish to
learn without running any great risk of falling when practising to ride. By
using it they are freed from the necessity of being held up by anyone when learn-
ing to pedal, or balance, because the pair of small wheels are placed so that one
will be at each side of the bicycle in readiness to prevent the rider swaying very
far to the right or left, out of the proper riding position..

page_text: All the attaching clips are designed so that they will not interfere in any way
with the working of the bicycle.
The accompanying drawings show the invention constructed in a suitable
form for convenient application, by means of clips, to ladies' or gentlemen's
bicycles they also include a figure (Fig: 6) showing how bottom or crank brackets
can be provided with suitable extra tube or bar holding projections, which will
serve for carrying the wheel holding part of this invention without the aid of the
above mentioned clips.
The same "letters" refer to the same parts in all the figures; and when the
word "bicycle" occurs, it shall hereinafter be taken as referring to those used
by ladies or gentlemen.
Fig. 1, is a side elevation showing method of connection to what is sometimes
called the front bottom tube (F. B. T.) of a bicycle, being the tube that connects
the bottom or crank bracket with the bottom of the steering socket tube S. S. T.
Front bottom tubes are generally made, straight on gentlemen's bicycles; and
those of ladies' bicycles are 'sometimes made straight and sometimes curved:
In Fig. 1, the connection is shown on a straight tube. When it is necessary to
apply the invention to a curved front bottom tube (F. B. T.) the connecting
pieces such as the clips and their appertenances must be made with their bearing
surfaces curved to suit them.
The clips and are in pair's and are made in size and form to suit the
particular part of the tube to which they will be attached.
In Fig. 1, clips el are shown a little away or clear of the tube socket of the
bottom or crank bracket. that is, just off the tube socket: but they can, if required,
be provided with an enlarged recess in part of their width so as to fit over the
tube socket projection.
The clips c¹ and may be joined together or made independant of each other.
One long pair of liners may be provided for use with both pairs of clips e¹
and or a separate pair may be used with each: if one pair is used, it will,
under certain conditions, be found best to fasten clips c¹ on to them and make
clips so that, they can be secured at any desirable position along length of
same arrows point out both directions of adjustment.
Clips c¹ may be made in one with the liners by being pressed, 'stamped, or casted.
in one piece: Clips 2 can also be made in one with the liners when they are not
required as adjustable clips.
Fig. 2 is a section through liners and tube at A. A., Fig. 1, G. E. are the guid-
ing edges which serve to prevent the front clips from twisting: The liners
can be made with, or without the guiding edges G. E.; they can also be made
with or without the swelled ends which will sometimes be found necessary to
fit over the tube sockets of the bottom or crank brackets.
Liners and all other, fittings that are brought in direct contact with the bicycle
are provided with a suitable facing of leather, cloth, felt, or other suitable
material.
To prevent the combined connection described above, from twisting on the
tube or part of the bicycle to which it is attached, link plates (L. P.) are used
which are connected to the top ends of clips c; one link under the head and
one under the nut of the bolt used for fastening the top ends of the clips: by
thus fastening them, they can be pointed at any angle to suit the saddle tube (S. T.)
of a gentleman's bicycle, or the front top tube of a lady's bicycle so as to engage
or form connection with them by the intervention of pairs of glands or blocks:
These glands or blocks are made in pairs for use with the above link plates:
One or more bolts are used with the link plates in addition to the holt used at
the top of the clips so as to tighten them on to the above mentioned blocks or
glands.
The twist preventing link connection consists of two slot links with
separate holes at one end: or links with a series of holes throughout their length.
See plans of both kinds Fig's 3.

page_text: One pair will generally be found sufficient as shown in Fig. 1, but. two or more
pairs can be used with a lady's or gentleman's bicycle if required: They can
be attached to clips in the same way as they are attached to clips c¹: Stretchers
may also be introduced within the tubes forming the bicycle frame for effecting
the same purpose.
The top ends of the clips can be extended to do service in the same way as
the links when the conditions of connection are favourable.
When the front bottom tube (F. B. T.) are curbed as is sometimes the case
with ladies' bicycles, the liners and clips must be made with a curvature to
suit them.
T. S. S. Fig. 1, show the tee screw suspenders; they are formed of one or
more pieces, the T heads of which serve as bolts at the bottom or under-side ends
of the clips for the fastening of same on to the bicycle tubes:
These tee screw suspenders allow of the wheel holding frame being regulated
and adjusted to any desirable working height within their length limits," which
is determined by the scope or space available at the underside of the bicycle
frame and between its front and back wheel.
In Fig. 1, the tee screw suspender (T. S. S. ) is shown provided with double
glands (D. G.) for holding the twin tubes (T. T.) of the wheel holding frame;
the hole of the top half can be screwed to suit the T screw and that of the bottom.
half can be plain to fit freely on same: or both can be made to fit freely on the
T screw: these double glands can be secured by means of nuts to any convenient
position on the T screw and on the twin tubes. The T screw suspender (T. S. S.³)
is provided with a cross head, each end of which is bolted on to the ends of the
twin tubes.
A hole is put through the centre of the cross-head which is screwed to suit
the tee screw suspender (T. S.S.2) or made to allow same to pass through freely:
nuts are fitted to the screw to hold the cross-head (C. H.) in any position within
the length limits of the tee screw suspender.
The suspenders (T. S. S. and T. S. S.2) are made long enough to enable users
of the invention to lower the wheels (S. W.) down to the ground or to lift them
away from the ground within suitable working limits.
Fig. 4, gives plan of position of front wheel (F. W.) and back- or hind
wheel (B. W.) showing the position of the small wheels (S. W.) forming in
conjunction with the back or hind wheel, the triangular wheeling base (T. W. B.).
Fig. 5, shows the arrangement of a pair of twin clips (T.C.) something like
horseshoes in shape; they are made with eliptic curves, so that they may be
adapted to crank brackets of different sizes, the inner edges are turned over so
as to form a good bearing surface the back ends are held in position with a T
bolt (T. B.) and cross bar (C. B.) this cross bar is laid across the sockets of the
tubes forming the back fork of the bicycle: the top parts of the twin clips are
bolted between the saddle tube and the front bottom tube (see T. C. B.). They
may also be bolted at their ends when they are far enough between the saddle
tube and the front part of the back wheel these twin clips are for holding the
tee screw suspender No. 1 (T. S. S.) on bicycles that will not admit of the first
kind of clips being fitted.
Fig. 6. shows how the crank bracket can be made with an additional socket
or pair of sockets with a tube or tubes on same, so that the twin tubes (T. T.) of
the wheel holding frame can be made to telescope into them the object of the
telescopic arrangement is to obtain an easy adjustment of the wheels and also
that users may the more easily put same on and off.
The wheel axle can be made straight; or otherwise, according to the particular
shape best suited to the machine that is to be fitted: the joining of same to the
twin tubes, may be, by brazing, cramping, or by any other suitable method that
will ensure a reliable joint: a spring joint may also be used with those intended
for rough roads.

The wheels may be made of any suitable material and can be fitted with plain
or ball bearing; the tyres may be of rubber, solid, cushion, or otherwise.
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 combination of parts such as those described in the foregoing specifica-
tion; modified and varied in material, and in construction for suitable application
to any and every kind of bicycle that is of a construction or design which corre
sponds in general details with those commonly known as lady's and gentlemen's
safety bicycles.
