COMPLETE SPECIFICATION.
A Detachable Screwed Sleeve or Clip for the Front Fork Stems of
Cycles, suitable for Ball or Socket Steering.
We, JOHN MARSHALL STARLEY, of 4 Radford Street, Coventry, Cycle
Manufacturer, and THOMAS GROVES, of Psycho Villas, Starley Road, Coventry,
Foreman Cycle Manufacturer, 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 consists of a sleeve of metal with a projection at one end slit to
form a
clamp or clip, and screwed at the other end; to this screwed end we fix a
lock nut and cone; the sleeve is now ready for sliding on the fork stem, and can
be fixed in any position, the cone being afterwards adjusted into its position. The
stem of the fork has a slit coinciding with a slit in the clip; by this means when
the clip is tightened, the handle bar stem (which slides inside of the fork stem tube)
is held in position and fixed simultaneously with the sleeve. The clip or clamp is
tightened by screwing up a bolt or screw.
Referring to the accompanying sheet of drawings which illustrates the application
of our invention :-
Figures 1, 2 and 3 are respectively front and side elevations and plan of our
metal sleeve slit to form a clip.
Figure 5 is a lock nut for adjusting the cone.
Figures 4 and 6 are respectively plan and elevation of a spring washer with
projection intended to secure the alignment of the slits.
Figures 7 and 8 are front and side elevations of our invention as applied, and
holding together the fork stem and handle bar stem.
Figure 9 shows portion of the fork stem with the required slit while
Figure 10 illustrates the handle bar stein as arranged to slide within the fork
stem.
Figure 11 is a side elevation of the cone and Figure 12 is a plan.
Figure 13 shows the screw bolt used for tightening up the clip or clamp.
The metal sleeve A Figures 1. 2 and 3 has proiections C slit at B and bored

page_text: for the screwing up bolt G Figure 13. One end of the sleeve is screwed as shown
to take the cone F, Figures 11 and 12 and the lock nut E Figure 5. The stem of
the fork H Figure 9 is slit as shown at H' Figure 9, the slit H¹ corresponding
to B and having a recess H to allow the passage of the bolt G which bolt G is
cleared to keep the interior of H an unbroken circle so as to pass the handle
bar stem I..
.
The spring washer K Figure 4 has a projection K¹ to pass through the
slit B in the sleeve, and secure the alignment or coincidence of the slit H
with B.
The sleeve A with the cone F, nut E and washer K is slipped over the fork
stem H, the projection K'taking the slit H'; the bolt G is then inserted so that
a flat on the head engages a check indicated by the line C Figure 2. The handle
bar stem I, is then slipped into place, and on screwing up the bolt G the clip or
clamp fixes the fork stem H by collapsing it at the slit H and compressing it on
the handie bar stem I.
The handle bar stem I, is thus firmly held and fixed simultaneously with the
sleeve and the position of the handle bar may be rapidly and securely adjusted.
The device in operation holding together the fork stem and handle bar stem is
clearly shown in front and side elevation at Figures 7 and 8 where the same letters
indicate the same parts as are shown separately in the other figures..
The upper part of the sleeve A is turned over as shown in Figures 1, 2, 7 and 8
to cover the end of the fork stem tube H and produce a neat finish.
By our arrangement the bolt G securely holds the several parts, and the said
bolt is prevented from being taken out till the handle bar stem is withdrawn by
reason of the recess shown in Figure 13.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
A detachable screwed sleeve or clip for the front fork stems of cycles suitable
for ball or socket steering, substantially as hereiubefore described and illustrated
in the accompanying drawings.
