Improvements relating to Cycle Saddles.
I, WILLIAM FRASER, of Dovedale, School Road, Moseley, near the City of
Birmingham, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention consists of improvements relating to cycle saddles, my objects
being to arrange more convenient means for adjustment of the position and tilt
or inclination of the saddle and for effectually securing it with the seat pillar,
and to provide supplementary supporting springs in combination with the
attachment lug or clip, such springs being readily adjustable to suit the weight
of the rider.
In the application of my invention I employ a U shaped lug embracing piece,
the closed upper end of such piece forming a base or seating for the central part
of the ordinary under frame of the saddle. The opposite and open end of the said
Ushaped part embraces the clip or clamping lug secured to the seat pillar and
is pivotted upon the bolt by which such clip or lug is tightened upon the tube or
pillar. Extensions of the open end of the U shaped embracing pieco below the
bolt are provided with slots or elongated apertures through which pass position
screws for securing the embracing piece, with the saddle resting upon and con-
nected to its upper end, at the desired tilt or angle to which it may be adjusted
within the limits fixed by the slots or elongated apertures. The clip or clamping
lug has suitable extensions from its under side to receive the position screws,
but such extensions are so arranged as to offer no obstruction to the lowering of
the seat pillar within the ordinary range of adjustment.
To prevent accidental canting or tilting movement of the saddle after adjust-
ment to the required position; I sometimes press out snugs or small projections
from the inner sides of the embracing piece which enter corresponding recesses
in the adjacent surfaces of the clip or clamping lug.
Between the ordinary underframe of the cycle saddle and the lower portion of
the embracing piece herein before described, I dispose spiral springs which can
be very readily adjusted, by means of nuts on the screwed ends of such springs, to
suit the weight of the rider.
The central portion or body of the clamping bolt I make of a fluted or serrated
form to engage corresponding rack like teeth or serrations formed on the
adjacent exterior surface of the seat pillar. On slackening the bolt and imparting
a rotating movement to the same its teeth gear with the rack on the tube and
thus the saddle can be readily adjusted longitudinally. I preferably form the
rack like teeth on the tube by a pressing or like operation and thus avoid the
loss of metal that would be incurred by cutting the teeth, and in such operation
I employ a two part mandrel for fitting within the tube to serve as a support for
the same, the surface or a portion of the surface of one part being serrated as
required for the formation of the teeth on the tube. By employing a two part
or segmented supporting mandrel or anvil I am enabled to very readily remove
the same from the tube at the conclusion of the pressing or stamping operation
for the serration of the tube.
I prefer to employ a seat pillar having a fluted or corrugated external surface,
or of a ☐ shaped section, and made from one piece suitably bent to the required

page_text: shape, rather than a tube formed from two parts in the ordinary manner; and
I sometimes employ a fluted or serrated bolt with corresponding tube teeth for
the adjustment of the height of the seat pillar, or I may employ a screwed rod
connected at its upper end to the seat pillar and with its lower end engaging
with a nut fixed within the adjacent tubular part of the cycle frame.
I modify the shape and arrangement of the clip or lug embracing piece and
of the sadille parts with which it is to be connected to suit varying requirements.
Dated this 6th day of July 1800
I, WILLIAM FRASER, of Dovedale, School Road, Moseley, near the City of
Birmingham, Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-.
tained, in and by the following statement:---
This invention consists of improvements relating to cycle saddles, my objects
being to arrange more convenient means for the necessary movement of the parts
when an adjustment of the saddle is required, and to provide supplementary
supporting springs, in combination with the saddle attachment lug or clip, which
shall be readily adjustable to suit the weight of the rider.
On the accompanying sheet of explanatory drawings to be hereinafter
referred to;―
Figure 1 is a side elevation, Figure 2 an end elevation, and Figure 3 an
inverted plan, showing my adjustment device.
Figure 4 is a side elevation and Figure 5 an endi elevation showing a modified
form of adjustment device in combination with the supplementary supporting
springs.
The same reference letters in the different views indicate the same or similar
parts.
In the application of my invention I employ a U shaped lug or embracing
piece as A, the closed upper end of such piece (in the example shown at Figures 1,
2, and 3) forming a base or seating for the central part B of the ordinary under
frame of the saddle. The opposite and open end of the said U shaped part
embraces the clip or clamping lug C secured to the seat pillar D and is pivotted
upon' the bolt. E by which such clip or lug is tightened upon the tube or pillar.
In the example shown at Figures 4 and 5 extensions of the open end of the
Ushaped embracing piece below the bolt E are provided, with slots or elongated
apertures through which pass position screws or a position bolt F for securing
the embracing piece, with the saddle resting upon and connected to its upper end;
at the desired tilt or angle to which it may be adjusted within the limits fixed by
the slots or elongated apertures. The clip or clamping lug C has suitable exten-
sions from its under side to receive the position screws, or position bolt.
To prevent an accidental canting or tilting movement of the saddle after adjust-
ment to the required position and before tightening the bolt F, I sometimes press
out snugs or small projections as a from the inner sides of the embracing piece A
which enter corresponding recesses in the adjacent surfaces of the clip or clamping
lug C.
In the example shown at Figures 1, 2, and 3, extensions of the open end of the

page_text: embracing piece A below the bolt E are dispensed with, and position screws
as F, passing through slots or elongated apertures in the sides of the embracing
piece A, are provided above the bolt E. The lines 0 and 0% at Figure 1,
represent the range of tilt or inclination.
.
Between the lower portion of the embracing piece A shown at Figures 4
and 5 and the bridge piece G to which the ordinary underframe of the cycle
saddle is secured, I dispose spiral springs as H which can be very readily adjusted
by tightening or slackening the nuts of the bolts J, to suit the weight of the
rider.
The central portion or body of the clamping bolt I make of a fluted or
Berrated form to engage corresponding rack like teeth or serrations K formed
on the adjacent exterior surface of the seat pillar D. On slackening the bolt
and imparting a rotating movement to the same its teeth gear with the rack
on the tube and thus the saddle can be readily adjusted longitudinally. I pre-
ferably form the rack like teeth on the tube by pressing or like operations and
thus avoid the loss of metal that would be incurred by cutting the teeth, and
in such operation I employ a two part mandrel for fitting within the tube to
serve as a support for the same, the surface or a portion of the surface of one part
being serrated as required for the formation of the teeth on the tube. By
employing a two part or segmental supporting mandrel or anvil I am enabled to
very readily remove the same from the tube at the conclusion of the pressing or
stamping operation for the serration of the tube.
I prefer to employ a seat pillar of a D shaped section, and made from one piece
suitably bent to the required shape, rather than a tube formed from two parts in
the ordinary manner; I sometimes employ a fluted or serrated bolt with corre-
sponding teeth on the handle tube for the ready adjustment of the height of
such part to correspond with the adjustment of the saddle. I also adopt the same
means for regulating the height of the seat pillar, or I may employ a screwed
rod connected at its upper end to the seat pillar and with its lower end engaging
with a nut fixed within the adjacent tubular part of the cycle frame.
I modify the shape and arrangement of the clip or lug embracing piece and
of the saddle parts with which it is to be connected, to suit varying requirements.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is.
1. The improved means for effecting the necessary movement of parts when
adjustment of a cycle saddle is required, comprising the use of a fluted or serrated
rotatable bolt engaging corresponding teeth or serrations in an adjacent tubular
part of the cycle, substantially as described.
2. The combination with the clip or clamping lug as C and the central part B
of a cycle saddle, of the embracing piece A radially adjustable upon the bolt E,
substantially as described and as illustrated.
3.-The combination with the clip or clamping lug as C and the central part B
of a cycle saddle, of the embracing piece A radially adjustable upon the bolt E,
the bridge picce G, and supplementary supporting springs as H interposed
between the said parts A and G, substantially as described and as illustrated:
4.—The general arrangement and combination of parts substantially as and
for the purposes described and as illustrated.
