PROVISIONAL SPECIFICATION.
Improvements in Cycle Seat-pillars, and in Means for Attaching the
Seat to the Pillar.
We, THE GARRISON CYCLE COMPANY, LIMITED, of Broadfield, Heywood, in the
County of Lancashire, Cycle Manufacturers, and JOHN BRENNAND, of the same
address, do hereby declare the nature of this invention to be as follows: —
The present invention has reference to the seat pillars of cycles and in the
means for attaching the seat to the pillars; its object is to avoid the twisting or
moving sideways of the seat which occurs when, with the ordinary round tube or
rod, the clamp or clip is not sufficiently tight.
In carrying our invention into practice, we make the top or horizontal member
of the seat pillar, to which the scat itself is clamped, of any regular geometrical
figure, preferably ☐ or segmental shape in cross-section, placed with its flat
surface uppermost and of course the convexity will be below. The top of the
other member of the pillar or tube into which the said horizontal member is fixed,
is also shaped to correspond with the latter, the two members being rigidly fixed
together forming practically, although not necessarily, one piece.
It will be obvious that this form of tube or bar affords the saddle attachment a flat
bearing surface and thus relieves the bolt or other fastening of such attachment
from all strain due to the tendency of the seat to twist or turn with the motion
and weight of the body.
The attachment of the seat to the horizontal member of the seat pillar is
effected by means of a divided clamp, the lower portion of which embraces the
horizontal member of the pillar, and the upper portion has two bevelled faces
or jaws and is bored through to receive the fixing bolt. Between the two jaws,
and correspondingly bevelled, is a triangular centre piece, or wedge, the base of
which rests upon the flat uppermost side of the horizontal bar of the seat pillar.
There is also provided on the inner surface of the clamp and the outer surface
of the said centre piece one or more tooth-like ridges or serrations, which, when
the clamping bolt is tightened up, engage with one another and thus effect a
better fit and consequently more rigid hold of the seat to the seat pillar as desired.

page_text: 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 present invention has reference to the seat pillars of cycles and in the
means for attaching the seat to the pillar; its object is to avoid the twisting or
moving sideways of the seat which occurs when, with the ordinary round tube or
rod, the clamp or clip is not sufficiently tight.
In carrying our invention into practice, we make the top or horizontal member
of the seat-pillar, to which the seat itself is clamped, of any regular geometrical
figure, either solid or hollow other than circular, preferably or segmental
shape, in cross-section, placed with its flat surface uppermost and of course the
convexity will be below. The top of the other member or stem of the pillar or
tube into which the said horizontal member is fixed, is also shaped to correspond
with the latter, the stem itself being cylindrical and either solid or hollow as
usual the two members being rigidly fixed together forming practically, although
not necessarily, one piece.
It will be obvious that this form of tube or bar affords the saddle attachment a flat
bearing surface and thus relieves the bolt or other fastening of such attachment
from all strain due to the tendency of the seat to twist or turn with the motion
and weight of the body.
The attachment of the seat to the horizontal member of the seat pillar is
effected by means of a divided clamp, the lower portion of which embraces the
horizontal member of the pillar, and the upper portion has two bevelled faces
or jaws and is bored through to receive the fixing bolt. Between the two jaws,
and correspondingly bevelled, is a triangular centre piece, or wedge, the base of
which rests upon the flat uppermost side of the horizontal bar of the seat pillar.
There is also provided on the inner surface of the clamp and the outer surface
of the said centre piece one or more tooth-like ridges or serrations, which, when
the clamping bolt is tightened up, engage with one another and thus effect a
better fit and consequently more rigid hold of the seat to the seat pillar, as desired.
In the accompanying illustrative drawings which are to be taken as part of this
specification and read therewith:-
Figure 1 represents in side elevation a cycle saddle, with support and clamp
constructed according to our invention.
Figure 2 is a transverse section of Figure 1 made on the line 2-2, and
Figure 3 illustrates various suitable sections other than round for the support-
ing bar and top lug of the seat-pillar.
Similar reference letters refer to different views of the same parts throughout
these drawings:
a is the saddle or seat which is rigidly fixed to the horizontal member 6 of the
seat-pillar c, by the specially constructed clamp, the lower portion e of which
embraces the member of the seat pillar and the upper bevelled portion f, form-
ing two jaws, the faces ¹ of which are formed to fit closely upon the central block,
is bored through to receive the fixing bolt g, which is tightened up by means of
the nuts m, m' and washers n, n¹. h is the triangular centre piece or wedge the flat
base of which rests upon the top j of the bar b. The inner surface of the clamp,
at k, and the outer surface of the centre piece or wedge h, at l, are provided as
shewn with tooth-like ridges or serrations which engage in one another when the
bolt g is tightened up, which affords the said parts a truer and consequently more
rigid fit, so that even the slightest lateral movement is impossible.
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:
1
1. A clamp for attaching the saddle or seat to the seat-pillar of a cycle, con-
sisting of a wedge-shaped central block the principal face of which is adapted

page_text: to rest closely upon the top bar of the seat-pillar; a metal strap adapted to fit
closely around the said top bar and central block, the sides of the block and inside
faces of the ends of the strap being provided with one or more longitudinal
ridges; a transverse hole through the strap ends and central block; a bolt adapted
to fit said hole, and washers and nuts; the whole being adapted to grip the seat
frame and seat-pillar, substantially as described and illustrated.
2. A pillar for supporting the saddle or seat of a cycle, consisting of a
cylindrical solid or tubular stem in the top end of which is fixed a solid or hollow
bar of other than circular transverse section.
