PROVISIONAL SPECIFICATION.
Improvements in or relating to Bicycles and similar Velocipedes.
I, George JosEPH BOWCOCK, of 127 Duke Street, Southport, in the County
of Lancaster, England, Gentleman, do hereby declare the nature of this invention
to be as follows:-
The object of my invention is to provide simple and reliable means, whereby the
steering rod or post and also the saddle bearer in bicycles, tricycles, and the like,
are firmly held, in order to prevent rotation, at the same time said parts may be
longitudinally adjusted.
My first improvement consists in forming upon the inside of the top lug or band
clip a suitable stud or projection to fit into a longitudinal slot, slit, aperture or
groove, extending a considerable length, in the steering rod or post. Said stud
also engages with a recess or slot formed in the upper portion of the fork stem.
A portion of this end of the stem is also cut away so as to provide a seat for a
corresponding part projected from beneath the flange of the top lug or band clip,
which is tightened upon the steering rod and fork stem, by means of a bolt and
nut in the ordinary way, and thus a rigid and reliable fastening is formed.
My second improvement relates to the saddle bearer, and consists in projecting
from the inside of said bearer, a stud, to fit into a longitudinal slot or groove made
in the saddle pillar, said bearer is also provided with the usual binding screw so
that it may be firmly held in position upon the pillar.
It may be here explained that the principle of my invention may be applied
with the same effect, to prevent the seat pillar from rotating in a similar manner
to that, for retaining the steering rod or post..

Improvements in or relating to Bicycles and similar Velocipedes.
1 GEORGE JOSEPH BOWCOCK of 127 Duke Street Southport in the County of
Lancaster, Gentleman 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 object of my invention is to provide simple & reliable means whereby the
steering rod or post of bicycles, tricycles or the like may be firmly held in place
in the fork stem in such manner as to prevent rotation therein & to afford ready
means for adjustment of same. The invention is also applicable to the saddle
bearer & seat pillar of cycles or the like.
Referring to the drawings
Fig. 1 is a vertical section of a steering rod, fork stem & band clip or lug
constructed according to my invention.

Fig. 4. section as on line A B Fig. 1.
Fig. 5 section as on line C D. Fig. 1.
Fig. 6 is an enlarged perspective view of the lug or band clip viewed from
beneath.
In these, a is the fork stem and 6 the steering post both shown as of tubular
metal as usual. c is the lug or band clip for adjustably retaining the relative
positions of the parts a & b. I form upon the inside of lug c a suitable stud or
projection d which in use fits into a longitudinal slot, slit, aperture or groove e in
the steering post & extending for a considerable length thereof. Said stud d
may also engage a slot in the upper edge of the fork stein a (see Fig. 5) and thus
tends when in place to prevent part from rotating relative to part a. To render
the fastening between lug c & fork stem a more secure, a portion of upper end of
the latter is cut away to form a recess f into which a corresponding shoulder g
projecting from beneath the flange of lug c fits. If thought preferable the stud d
need not be so long as to engage fork stem a, as sufficient safeguard against
rotation is provided by the shoulder g & recess f, but the stud is stronger when
made of full length as shown.
The lug c is tightened in place by means of bolt & nut h, so as to grip both
steering post & fork stem. The latter has a cut i to render it sufficiently yielding
to give a tight joint.
In the drawing I have shown the steering post as grooved to receive stud d &
reinforced inside with metal but if desired I may provide a simple slot ĉut right
through the metal instead.
The invention is also applicable to the adjustable saddle bearer, back tubular
pillar, or other adjustable portions of cycles when prevention of rotation is
desirable, in place of the usual band clip.
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 lug or band clip for use in cycles having a stud or projection adapted to
fit into slots or grooves made to receive it on two pieces adjustable longitudinally
one within the other, substantially as and for the purposes described.
2. The improved device for adjustably fastening two longitudinally movable
pieces in desired relative position in such manner as to prevent rotation of one
within the other comprising lug or band clip c & slots or grooves such as e, and
recess & projecting shoulder such as ƒ and g substantially as & for the purposes
set forth.
3. The improvements in bicycles & similar velocipedes substantially as described
& shown.
