PROVISIONAL SPECIFICATION.
Improvements in the Construction of Framework for Bicycles and
other Velocipedes or the like.
I, JOHN WILLIAM ASTLEY, trading as The Central Electrical Engineering Com-
pany, of 19, Fold Street, Bolton, in the County of Lancaster, Engineer, do hereby
declare the nature of this invention to be as follows, that is to say:-
.
It has reference to the production of framework for bicycles and other
velocipedes or the like, wherein metal tubes are employed and consists
in constructing the jointing parts where one tube is secured to another to form
the framework of the design or shape desired in such a manner that the said
resultant framework is as strong and firm at these joining places or joints as it
is in any other part, while the method of construction which I follow in the
production of said framework permits one part (such as one that may by any
means become damaged when the vehicle is in use) being detached from another
for repairs or to be displaced by a new and perfect part and that without in
any way damaging or weakening the other parts of said framework.
In carrying my invention into effect I employ tubing of the usual well know
kind the same being cut into lengths to meet the varied requirements for pro
ducing the shape or class of framework desired.
At those ends of these pieces of tubing which are to be secured to the jointing
pieces or other parts to form the framework, I form screwed threads so that they
may be screwed into said jointing pieces or other parts which have correspondingly
screwed threads to fit them, after which I pass a bolt, rivet or holding pin, (which
may be solid or hollow) crosswise or diametrically through both the jointing piece
and the tubing.

strengthening tube within the other to be strengthened and then squeeze or indent the
screwed thread into both of them by which means one is firmly secured to the
other, after which they are screwed into the jointing piece and further secured as
above described.
In the securing of the tubes to the jointing pieces I preferably use a bolt which
is made in two parts the one taking into the other within the tube by which
means when these are screwed or tightened up as desired and then their heads
squeezed or otherwise bent to conform to the convexity of the jointing piece
they are held from rotating and becoming loose.
Instead of using bolts, pins or the like for securing the tubes together and to
the jointing pieces, I may screw the parts together and then indent or impress
them in certain positions so that the unscrewing of any of them is entirely pre-

Improvements in the Construction of Framework for Bicycles and
other Velocipedes or the like."
I, JOHN WILLIAM ASTLEY, trading as The Central Electrical Engineering Com-
pany, of 19, Fold Street, Bolton, in the County of Lancaster, Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following state-
ment, that is to say:-
It has reference to the production of framework for bicycles and other
velocipedes or the like wherein metal tubes are employed and consists
in constructing the jointing parts where one tube is secured to another to form
the framework of the design or shape desired, in such a manner that the said
resultant framework is as strong and firm at these jointing places or joints as it
is in any other part, while the method of construction which I follow in the
production of said framework permits of one part (such as one that may by any
means become damaged when the vehicle is in use) being detached from another
for repairs or to be displaced by a new and perfect part and that without in
anyway damaging or weakening the other parts of said framework.
In the accompanying sheet of drawings:
Figs. 1 and 2 are sectional side and end views of sufficient portions of a tube
and bracket or part to which it is secured to illustrate my invention.
Figs. 3 and 4 are similar views to Figs. 1 and 2 but illustrate modifications
hereinafter explained.
Figs. 5 and 6 are also illustrative of modified forms of construction hereinafter
described.
In carrying my invention into effect I employ tubing of the usual well known
kind the same being cut into pieces of proper. length to meet the varied require-
ments for producing the shape or class of framework desired.
At those ends of the said pieces of tubing a which are to be secured to the joint-
ing pieces or other parts 6 to form the framework, I form screwed threads a¹
so that they may be screwed into said jointing pieces or other parts b which have
correspondingly screwed threads to fit them, after which I pass a bolt c (Figs. 1
and 2) or d (Figs. 3 and 4) or a rivet or pin ƒ (Figs. 5 and 6) crosswise or dia-
metrically through both the tube a and piece b.
When necessary, to strengthen the tubing a at and near the part where it enters
the part I insert another piece of tubing g shown in broken lines Figs. 1 and 2,
or this said piece may be placed over the tubing a as shown at g¹ by Figs. 5
and 6, or a metal ring or bush h shown by Figs. 3 and 4 may be used in place of
this part g by its being placed within.
The several parts, that is the tubes a the strengthening pieces g and h and the
parts b may be secured by soft solder which can be readily melted to allow the
detachment of any damaged pieces whenever desired provided it is thought
advisable to make use of this further means of attachment.
I preferably place the strengthening piece g within the piece a and then squeeze
or indent the screwed thread into both of them by which means one is firmly

page_text: secured to the other after which they are screwed into the piece b and then secured
by the bolts c d or the rivet f.
The bolt c is, in accordance with my invention formed in two parts 2 and 3,
the part 2 taking into the part 3 so that when they are firmly screwed together
within the tube a and parts b, and on their heads c c coming into contact with
the outer surface of the part b, by pressing and bending these heads so that they
will conform to the circular shape of the surface they are in contact with as shown
by Fig. 2, they will prevent the parts 2 and 3 from rotating or becoming loose,
although such bended form of these heads will not prevent the parts 2 and 3
from being rotated by the use of a powerful screw driver whenever they are
required to be detached.
Or the bolt c may be formed as shown by Figs. 3 and 4, its part 5 being made
taper to fill the tapering hole made to receive it in the several pieces a band h,
while a nut having a similar tapering part 8 and a flange k (which latter is
to be bent upon the part 6 as shown by Fig. 4 to prevent its becoming loose as
does the bending of the head c¹ that of the bolt c) may be used, and this affords
better facilities for detachment when necessary.
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. Framework for bicycles and other velocipedes or the like produced by the
joints or jointing parts being constructed substantially as herein specified.
