Improvements in the Saddle Pillar Tubes of Bicycles, Tricycles,
and other Velocipedes, and in Connecting Saddles to the same.
1, FREDERICK JOHN OSMOND, of Ravenswood, Chantry Road, Moseley, in the
County of Worcester, Works Manager do hereby declare the nature of this
uvention to be as follows:-
My invention has for its object to facilitate the connection of the saddles of
bicycles, tricycles and other velocipedes to the frames of the said bicycles, tricycles
and other velocipedes and to permit of the tilting of the saddles on the saddle pillar
tubes so as to make any desired angle therewith.
My improvements in the saddle pillar tubes consist in forming on the top of the
said tubes, in either of the ways hereinafter described, tubular heads the said
tubular heads crossing the saddle pillar tubes at right angles and giving to them a
form somewhat resembling the letter T. Through the tubular head the saddle
fixing screw bolt passes as hereinafter described.
I close each end of the tubular head of the saddle pillar tube by means of a
pair of discs or washers a portion of the inner washer of each pair being reduced
in diameter so as to enter the tubular head. The pair of washers on the one side
of the tubular head is connected to the pair of washers on the opposite side by
means of the fixing bolt herein before referred to, the said fixing bolt passing through
central holes in the washers and being provided with a screw nut at its screwed end
so as to clamp the washers to the tubular head. I make in the abutting faces of
the pairs of washers, grooves for receiving the wires or rods of the frame or
foundation of the saddle.
In fitting a saddle to the saddle pillar tube head hereinbefore described the bolt
and outer washers are removed and the frame or foundation of the saddle is applied
to the said head, the wires or rods of the said saddle frame or foundation taking
into the grooves in the outer faces of the inner washers; the outer washers are
applied to the said head aud the whole is bolted together the wire frame or
foundation being firmly held between the two washers on each side of the tubular
head. When it is desired to alter the inclination of the saddle it is only necessary
to relax the pressure of the screw bolt when the said washer can be turned in
the tubular head and the whole refixed in its changed position by tightening the
screw bolt.
When the saddle has a frame or foundation composed of two slotted bars, the
grooves in the washers are dispensed with the bolt passing through coincident slots
or perforations in the said frame bars and the said bars are bound firmly between
the pairs of washers on each side of the tubular head.
The outer washer on the bolt head side of the connection may be dispensed
with, the head of the bolt being made of large diameter and with crossing grooves
for taking upon the wires or rods of the saddle frame.
Or in place of the pairs of washers on either side the tubular head, one washer
at each side only may be employed. In this case I form on the inner side of each
washer a tubular flange for fitting within the tubular head. The tubular flange
described is cut away at opposite sides to receive the wires or bars of the saddle
frame.
I make the tubular head on the seat pillar tube in either of the following ways.
5 I split the top of the seat pillar longitudinally at opposite sides and flatten and
open out the two portions formed by the splitting of the said tube I place between

page_text: the fork of the opened out tube a cross tube and close and braze the opened out
and flattened portions of the seat tube upon the short cross tube.
Or I take a T shaped tube and braze the stem of the said T shaped tube in or
on the saddle pillar tube. The crossing or horizontal portion of the T shaped tube
may be angular instead of circular externally as may be desired.
.
Or instead of arranging the tubular head on the top of the saddle pillar tube it
may be arranged on the side of the said tube.
Or I form the said head by passing the seat pillar tube through the short crossing
tube and make a hole through the seat pillar tube concentric with the short crossing
tube, the said hole being of a size large enough to allow the fixing bolt to pass
through.

COMPLETE SPECIFICATION.
Improvements in the Saddle Pillar Tubes of Bicycles, Tricycles,
and other Velocipedes, and in Connecting Saddles to the same.
I, FREDERICK JOHN OSMOND, of Ravenswood, Chantry Road, Moseley in the
County of Worcester, Works Manager do hereby declare the nature of my inven-
tion and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement :-
My invention has for its object to facilitate the connection of the saddles of
bicycles tricycles and other velocipedes to the frames of the said bicycles, tricycles
and other velocipedes and to permit of the tilting of the saddles on the saddle pillar
tubes so as to make any desired angle therewith.
My improvements in the saddle pillar tubes consist in forming on the top of the
said tubes, in either of the ways hereinafter described, tubular heads the said
tubular heads crossing the saddle pillar tubes at right angles and giving to them
a form somewhat resembling the letter T. Through the tubular head, the saddle
fixing screw bolt passes as hereinafter described.
I close each end of the tubular head of the saddle pillar tube by means of a
pair of discs or washers a portion of the inner washer of each pair being reduced in
diameter so as to enter the tubular head. The pair of washers on the one side of
the tubular head is connected to the pair of washers on the opposite side by means
of the fixing bolt herein before referred to, the said fixing bolt passing through
central holes in the washers and being provided with a screw nut at its screwed end
so as to clamp the washers to the tubular head. I make in the abutting faces of
the pairs of washers, grooves for receiving the wires or rods of the frame or
foundation of the saddle.
In fitting a saddle to the saddle pillar tube head herein before described the bolt
and outer washers are removed and the frame or foundation of the saddle is
applied to the said head, the wires or rods of the said saddle frame or foundation
taking into the grooves in the outer faces of the inner washers; the outer washers
are applied to the said head and the whole is bolted together the wire frame or
foundation being firmly held between the two washers on each side of the tubular
head. When it is desired to alter the inclination of the saddle it is only necessary
to relax the pressure of the screw bolt when the said washer can be turned in the
tubular head and the whole refixed in its changed position by tightening the
screw bolt.
When the saddle has a frame or foundation composed of two slotted bars, the
grooves in the washers are dispensed with, the bolt passing through coincident slots
or perforations in the said frame bars and the said bars are bound firmly between
the pairs of washers on each side of the tubular head.

page_text: The outer washer on the bolt head side of the connection may be dispensed with,
the head of the bolt being made of large diameter and with crossing grooves for
taking upon the wires or rods of the saddle frame.
Or in place of the pairs of washers on either side the tubular head one washer at
each side only may be employed. In this case I form on the inner side of each
washer a tubular flange for fitting within the tubular head. The tubular flange
described is cut away at opposite sides to receive the wires or bars of the saddle
frame.
Figures 1, 2, 3 and 4 of the accompanying drawings represent a portion of the
saddle pillar tube of a velocipede constructed according to one of the arrangements
of my invention; Figure 1 represents the saddle pillar tube in side elevation and
Figure 2 represents the same in plan; Figures 3 and 4 are vertical sections taken
in planes at right angles to one another.
The same letters indicate the same parts in the several figures of the drawings.
b is the saddle pillar tube of a velocipede and 6 is the tubular head of the same.
The ends of the tubular head 62 are closed by means of the perforated discs or
washers d, d at each side of the tubular head 62, the diameter of the inner faces of
the said washers d, d being reduced so as to permit them to take into the tubular
head (see Figure 4).
In conjunction with the said closing washers d, d other washers c, c constituting
gripping washers are used.
The pair of washers C, d on the one side of the tubular head 62 are connected to
the pair of washers c, d on the other side, and the said washers are also connected
to the tubular head 2 by the screw bolt e and nut e². I make in the abutting or
opposed faces of the washers, grooves into which the wires t, t of the saddle frame
or foundation take when the saddle is connected to the velocipede.
In connecting the saddle to the saddle pillar tube the screw bolt e and outer
washers c, c. are removed and the wires t, t of the saddle frame are applied to the
tubular head of the saddle pillar tube the said wires t, t fitting in the grooves
in the outer faces of the inner washers d, d. The outer washers c, c and bolt e are
placed in position and the screw nut e³ is screwed tightly home so as to grip the
wires of the spring frame or wire foundation of the saddle between the pairs of
washers c, d and bind the said washers to the tubular head b².
"
When it is desired to alter the inclination or tilt of the saddle it is only necessary
to relax the pressure of the screw bolt and nut e, e² and turn the saddle into the
inclined position desired, the axis of the tubular head constituting the centre on
which the saddle turns. On the turning of the saddle the pairs of washers c, d
turn with respect to the tubular head 2. The parts are refixed by tightening the
screw nut e on the screw bolt e.
When it is desired to readjust the position of the saddle the pressure of the
screw bolt and nut is relaxed and the saddle is moved either forward or backward
into the position desired the wires of the frame moving longitudinally in the
grooves in the opposed faces of the relaxed washers c, d. The parts are refixed in
their changed position by tightening the screw nut e² on the screw bolt e.
Figure 5 represents in vertical section and side elevation a modified form of the
clip Figures 1, 2, 3 and 4. In this case the stem of the bolt is made in one piece
with one of the outer washers e the said stem being marked c. The action of this
arrangement is the same as that previously described and corresponding parts are
marked with the same letters of reference.
Figure 6 represents a modification in which the inner ends of the inner
washers d, d are conical (as will be best seen by reference to the detached washer
Figure 7) and the tubular head 62 has corresponding hollow conical faces or seats,
the conical ends of the washers d, d fitting against the conical seats of the tubular
head b. By this means on the tightening of the screw nut e³ on the screw bolt c³
the pairs of washers c, d are more firmly bound to the tubular head 6' than in the
arrangements previously described.
Figures 8 and 9 represent sections taken in planes at right angles to one another
•

page_text: of a modification in which only one washer at each side is employed the said
washers having projections c, c which fit within the tubular head 6. This
modification is principally applicable for use and is represented in connection
with a frame made of slotted bars g, g but the said modification may be used with
wire frames.
I make the tubular head 62 on the seat pillar tube 6 in either of the following
ways.
In making the arrangement represented in Figures 1 to 9 both inclusive I take
a tube of a slightly greater length than the seat pillar tube to be made. I split
one of the ends of the said tube at opposite sides as indicated in dotted lines in
Figure 1 and then plate out or flatten the split portions (which are marked 6*) as
indicated in dotted lines in Figure 3. I place between the fork formed by the
flattened ends 63, 63 a short tube a the axis of the said tube a crossing that of the
seat pillar tube b at right angles. The ends 63, 63 are closed upon and brazed to
the tube a and the tubular head 62 is thereby finished. When the tubular head 6*
is required to have hollow conical seats or ends as represented in Figure 6 the
tube a must have hollow conical ends or faces.
Or I form the tubular head 62 by taking a T shaped tube h and brazing the stem
on or in the seat pillar tube b as represented in Figures 10 and 11. The crossing
part of the T shaped tube h in Figure 11 has an angular figure externally.
In Figures 12 and 13 I have represented the crossing tube 63 on the side of the
saddle pillar tube instead of on the top of the said saddle pillar tube. By this
arrangement a greater range of motion is permitted in the adjustment of the saddle
as the saddle pillar tube may be turned through a semi-circle thereby bringing the
crossing tube to the back or front of the said saddle pillar tube.
In Figures 14 and 15 the tubular head 62 is made of a short crossing tube of
much larger diameter than the saddle pillar tube, the said saddle pillar tube passing
through holes at opposite sides of the said crossing tube. The saddle pillar tube b
has small holes 6, at opposite points for the bolt e to pass through, the axis of
the small holes 6, 6 being coincident with that of the short crossing tube 62 fitting
on the top of the saddle pillar tube b._
Having now particularly described and ascertained the nature of my inven
tion and in what manner the same is to be performed I declare that I claim as
my invention of "Improvements in the saddle pillar tubes of bicycles, tricycles
and other velocipedes and in connecting saddles to the same
"
:-
Forming on or attaching to the top of the seat pillar tube a short crossing tube
or tubular head and the combination with the said tubular head of washers and a
screw bolt and nut whereby the saddle frame is attached to the seat pillar tube so
as to be capable of adjustment and tilting, the several parts being constructed,
combined and acting substantially as herein before described and illustrated in the
accompanying drawings.
