PROVISIONAL SPECIFICATION.
Improvements in Clips for Sliding or Telescopic Joints.
I, GEORGE JOHN STEVENS, of No. 95, Falmouth Road, in the County of
London, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in clips for sliding or telescopic joints
such as the seat pins or tubes of cycles, cycle handle bar stems and saddles,
lamp holders, break levers, and other sliding or telescopic joints.
For the purpose of example I will describe my invention as applied to the seat
pin or tube of a cycle.
Through the crutch piece of the frame I make a hole transversely to the axis
of the socket in which the seat pin slides, such hole partly opening into the said
socket. In the said hole at each end thereof I fit a gripping block the inner
surface of which is shaped so as to fit against the sent pin; through the said
gripping blocks is a hole through which passes a bolt by screwing up which, the
blocks are brought towards one another thereby firmly gripping the seat pin in
the position to which it has been adjusted.
By the use of my improved clip I avoid the necessity of cutting or splitting
the frame, and provide a clip which allows of the seat pin being adjusted and
fixed in position with much greater speed and facility than by the method of
clipping hitherto in use.

Improvements in Clips for Sliding or Telescopic Joints.
I, GEORGE JOHN STEVENS, of No. 95, Falmouth Road, in the County of
London, Engineer, 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 improvements in clips for sliding or telescopic joints
such as the seat pins or tubes of cycles, cycle handle bar stems and saddles, lamp
holders, brake levers, and other sliding or telescopic joints.
In applying my invention to the seat pin or tube of a cycle, I form through the
crutch piece of the frame a hole transversely to the axis of the socket in which the
seat pin slides, such bole partly opening into the said socket. In the said hole at
each end thereof 1 fit a gripping block the inner surface of which is shaped so as
to fit against the seat pin; through the said gripping blocks is a hole through
which passes a holt by screwing up which the blocks are brought towards one

page_text: another thereby firmly gripping the seat pin in the position to which it has been
adjusted.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawings, in which :-
Figure 1 is an elevation of the portion of a bicycle frame carrying the seat pin
and shewing my clip applied:
Figure 2 is a sectional plan of the same the section being on the line 2-2
Figure 1; and,
Figure 3 is a plan of the clip detached:
Figure 4 is a side elevation shewing my clip applied for clamping the handle bar
of a cycle:
Figure 5 is a section on the line 5-5 Figure 4:
Figure 6 is a sectional elevation shewing the arrangement of the clip for an
alternative form of handle bar.
a indicates the tube to be clamped or held in position and 6 is the tube or socket
in which the said tube a slides.
c, c are my gripping blocks and d is the screw or bolt for tightening the clip by
screwing the blocks towards each other. The blocks c, c are fitted into holes
formed through the sides of the socket b in a manner which will be readily
understood by reference to Figure 2 so that when the screw d, which passes freely
through one block and is screw-threaded into the other block, is in position and
tightened up, the blocks c, e will be clamped firmly against the tube a.
By the use of my improved clip in connection with the socket in which the seat
pin slides, as shewn in Figures 1 and 2, 1 avoid the necessity for cutting or splitting
the said socket whereby the frame which is made as shewn in Figure 2 is
stronger than heretofore.
In the arrangement of my invention shewn in Figures 4 and 5 the clip is applied
to the usual tubular socket b in which the stem a of the handle bar slides. The
arrangement of the clip, which is clearly shewn in Figure 5, is precisely the same
as that shewn in Figures 1 and 2.
The arrangement of my invention shewn in Figure 6 illustrates the application
of my clip to a handle bar which is adapted to be adjusted by rotating it upon its
axis. In this case the socket which in the arrangement shewn in Figure 4 served
to receive the stem of the handle bar, now serves to receive the clipping blocks c, c
and the screw d.
The great advantage of my improved clip is that whilst affording great security
it allows of the parts being adjusted and fixed with much greater speed and facility
than by the methods of clipping hitherto in use.
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. A clip for preventing the movement of two tubes relatively with one another
comprising two blocks carried in one of the said tubes the said blocks having
curved faces adapted to fit against the tube and being designed to be moved
towards each other by a screw, substantially as described.
2. A clip for joints constructed, arranged and operating substantially in the
manner hereinbefore described and illustrated in the accompanying drawings.
