Improvements in or relating to Cycles.
I, JAMES RICHARD TRIGWELL of 146 Brixton Hill, in the County of Surrey,
Cycle Manufacturer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to the means for supporting the seats or saddles of cycles
and is intended as an improvement upon the Patent already granted to Count
Charles de Rosetti, No. 22938 of 1893.
In carrying out this invention I support the saddle entirely upon strained cables
carried in any convenient manner say for example around pulleys at the front and
back of the machine. I preferably employ two endless cables forming two
supports upon each side of the framework of the machine and I connect the saddle
to these by any convenient arrangement of clips or supporting devices adapted to
grip the cables.
One advantage of my invention is that I can apply it to existing machines
without any structural alteration of the framework. I will describe it as applied
to a safety bicycle, but it will be understood that with or without modifications it
may be applied to other forms of cycles. With the ordinary bicycle I take the
usual or a special L-pin or saddle support which may be carried in the ordinary
manner in the framing and through the horizontal limb of this I place a preferably
tubular arm which I fix in the L-pin by any convenient clamping arrangement, a
suitable way being to split the L-pin and by means of a clamp and bolt and nut
upon
tighten it up upon the tubular arm so that the position of the latter in the
L-pin can be adjusted at pleasure. The back pair of pulleys are carried upon this
tubular arm which may if desired be supported by a link pivotted to the arm and
also to a clamping device by which it may be connected with a suitable portion of
the frame of the machine. This link I prefer to be tubular with a short bolt or
adjustment screw screwing into its back end and suitably connected with the end of
the tubular arm so that if the latter be free in the L-pin by turning the adjustment
screw the position of the tubular arm and consequently the pulleys which it carries
can be altered so as to strain or tighten the saddle supporting cables. I am thus
enabled to tighten these cables as much as may be necessary and modify the
tightness or otherwise of the saddle support which is by this means exceedingly
free while the cables absorb vibration and as the saddle can be adjusted backwards
and forwards upon the cables and can be raised or lowered by altering the L-pin
in the usual manner and can also be tilted upon its own ordinary supports or upon
the special supports provided any suitable adjustment can be obtained.
The ordinary saddle springs may be employed if desired or may be dispensed
with.
Supports or guides may be provided for the cables if required though I have
obtained excellent results without these.
Simple wires or cables supported at each end may be employed instead of the
endless bands previously described suitable means of tightening them being
provided.

page_text: I, JAMES RICHard Trigwell of 146 Brixton Hill, in the County of Surrey,
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 relates to the means for supporting the seats or saddles of cycles
and is intended as an improvement upon the Patent already granted to Count
Charles de Rosetti, No. 22938 of 1893.
In carrying out this invention I support the saddle entirely upon strained cables
carried in any convenient manner say for example around pulleys at the front and

One advantage of my invention is that I can apply it to existing machines
without any structural alteration of the framework. I will describe it as applied
to a safety bicycle, but it will be understood that with or without modifications it
may be applied to other forms of cycles. With the ordinary bicycle I take the
usual or a special L-pin or saddle support which may be carried in the ordinary
manner in the framing and through the horizontal limb of this I place a preferably
tubular arm which I fix in the L-pin by any convenient clamping arrangement, a
suitable way being to split the L-pin and by means of a clamp and bolt and nut
upon it tighten it up upon the tubular arm so that the position of the latter in the

this tubular arm which may if desired be supported by a link pivotted to the arm
and also to a clamping device by which it may be connected with a suitable portion
of the frame of the machine. This link I prefer to be tubular with a short bolt
or adjustment screw screwing into its back end and suitably connected with the
end of the tubular arın so that if the latter be free in the L-pin by turning the
adjustment screw the position of the tubular arm and consequently the pulleys
which it carries can be altered so as to strain or tighten the saddle supporting
cables. I am thus enabled to tighten these cables as much as may be necessary
and modify the tightness or otherwise of the saddle support which is by this
means exceedingly free while the cables absorb vibration and as the saddle can

Like letters indicate like parts throughout the drawings.

page_text: The horizontal portion of the L-pin A is split and provided with a clamping
collar A¹ by means of which the tube rol or bracket B sliding within the L-pin A
may be securely fixed, this tube B projects at the rear of the machine and has a
cross piece formed at its free end upon which are suitably secured two pulleys C.
A collar D which may be clamped by means of a bolt and nut D' upon the down
tube E of the framing of the machine has guide pieces D2 formed on either side
of it and a lug D³ at the rear to this lug is pivotally secured a tube F to the
free end of which is attached, preferably by brazing an internally screw threaded
nut F, with which engages a screw threaded bolt or rod F2; this rod has a
hexagonal milled or other head F³ formel upon it by means of which it may
readily be turned, and also an extension F4 which engages with an opening in the
cross piece on the end of the tube B between the pulleys C, thus by loosening the
clamp A and turning the screw F2 the tube B is adjusted either forward or
backward. A collar G carrying attached to suitable lugs or projections on it the
pulleys H is securely fastened to the steering post J or other convenient part of
the machine. Over the pulleys C and H pass the two endless cables K.
The saddle L has securely attached to it supporting pieces M preferably of some
such shape as shown in Figure 1, these supporting pieces are conveniently two
in number though more than two or even a single broad piece may be employe l
if desired. The ends of these supporting pieces M are provided with clamps M¹
which embrace the upper and lower portions of the cables K and enable the
saddle to be securely attached to the latter. A guide piece N provided with a
nut N¹ by means of which it may be adjustably secured to the end of the tube B
which projects on the forward side of the L-pin, is arranged so that its lower
portions rest on the guide pieces D2 on the collar D; this guide piece N is so
adjusted relatively to the supporting pieces M that it may control the lateral
movement of the saddle. It will be seen that the tension of the cables K may be
regulated by means of the fore and aft adjustment of the tube B in the -pin A
together with the arrangement for altering the length of the tube F above
described.
The modification illustrated in Figure 3 is specially constructed with a view to
ladies' use.
In this arrangement the cables are doubled back so as to be fourfold
on either side.
A short tube A2 is clamped or otherwise secured in the L-pin A, the front end
of this tabe is split and carries a clamp A¹ by means of which the short tube B¹
is firmly held; the hinder end of the tube A2 has a screw threaded collar formed
upon it and an internal feather A, the tube or bracket B having a similar screw-
threaded collar B2 slides freely in the tube A2, the feather A engaging with a
keyway cut in the tube B. The screw threads on the collars A³ and B3 are right
and left handed, and a nut B having corresponding screw threads engages with
the collars A B in such a manner that by rotating this nut B the tube B¹
carrying the pulleys C may be moved so as to take up any slack in the cables K,
the feather A preventing the tube B and pulleys from slewing while being so
adjusted. If desired the forward end of the tube A¹ and the tube or bracket B¹
may have a similar adjustment; this tube B¹ together with the short rod O
attached to the collar D support the three pairs of pulleys H H and H2 which are
carried by two side plates P. The collar D clamped on the down tube E, besides
the rod O pivotally attached to its forward side, has formed on its hinder side a
rod D' which carries a pair of pulleys C2. The endless cables K on each side
pass as shown over the pulleys in the following order :-C, H, H³, C³, H', and
again over C. The supporting pieces M are attached by means of the clamps M¹
to the cables K in a manner similar to that described in reference to Figure 1.
In this modification it is not necessary to employ a guide piece such as N
(Figure 1) though a suitably shaped piece may be arranged if desired. It is
obvious that other means of adjusting the pulleys than those described above may
equally well be employed.
Though the parts B, B' and F have been described above as being made tubular

page_text: for the purpose of lightness, it must be understood that if desired they may be made
solid, being constructed of aluminium for example.
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 detachable strained cable saddle supporting device for cycles.
2. The combination with a cycle of a saddle supported upon strained cables
attached to the framing in the manner described.
3. In a saddle attachment for cycles the combination with supporting pieces such
as M of strained cables guide pieces N, collar such as D and pulleys such as C H
whereof two are adjustably connected with the framing for the purpose of
tightening the cables substantially as described and illustrated in Figure 1 of the
accompanying drawings.
4. In a saddle attachment for cycles the combination with supporting pieces
such as M of strained cables, collar D and pulleys C H H H adjustably connected
and pulley C² rigidly connected with the framing substantially as described and
illustrated in Figure 3 of the accompanying drawings.
5. In a saddle attachment for cycles the combination with strained cables of
pulleys C carried or supported by an adjustable bracket such as B and tube such
as substantially as described and illustrated in Figures 1 and 2 of the
accompanying drawings.
6. In a saddle attachment for cycles the combination with strained cables of
pulleys carried by a bracket such as B adjustable in a tube such as A'
substantially as described and illustrated in Figure 3 of the accompanying
drawings.
"
7. In a saddle attachment for cycles the combination with strained cables of
pulleys H, H, H2, carried by side plates such as P and adjustably connected to
the framing by a bracket such as B' and link O substantially as described and
illustrated in Figure 3 of the accompanying drawings.
8. The combination and arrangement of parts constituting the complete saddle
supporting device substantially as described and illustrated in Figures 1 and 2 or
in Figure 3 of the accompanying drawings.
