PROVISIONAL SPECIFICATION.
An Adjustable Mount for Cycle Saddles.
i, WILLIAM HENRY MCLAUCHLAN, of Manor House, Cheylesmore, Coventry,
in the County of Warwick, Mechanical Engineer, do hereby declare the nature of
this invention to be as follows:-
The object of my invention is to provide means of adjusting the saddle of a
bicycle or other like machine in a backward or forward direction so as to place the
rider in the most advantageous position for pedaling on level ground or hills as
the case may be and to effect such adjustment with the utmost ease and quickness.
To the saddle bar I attach a parallel motion moveable in a longitudinal direction
and to this parallel motion I attach the saddle instead of directly to the saddle bar.
Various constructions of parallel motions may be used to carry my invention into
effect.
For example, one construction which I use is similar to the well known parallel
ruler having two parallel bars joined by link bars which are at right angles to the
parallel bars when the same are furthest apart. The upper of the two bars is
inoveable longitudinally and to this bar the saddle is fixed.
Or the upper and inoveable bar of the required parallel motion to which the
saddle is to be attached may slide upon roller or other bearings on the lower or
fixed bar.
In all cases the moveable bar carrying the saddle may be fixed in the required
backward or forward position by a cam, screw, wedge or other suitable fastening
to prevent movement of the saddle when adjusted.
By means of my invention a rider can move his saddle backwards or forwards
as required by the nature of the road without dismounting from his machine.

COMPLETE SPECIFICATION.
An Adjustable Mount for Cycle Saddles.
I, WILLIAM HENRY MCLAUCHLAN, of Manor House, Cheylesmore, Coventry,
in the County of Warwick, Mechanical Engineer, 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 means of adjusting the saddle of a
bicycle or other like machine in a backward or forward direction so as to place the
rider in the most advantageous position for pedaling on level ground or hills as
the case may be and to effect such adjustment with the utmost ease and quickness.
To the saddle bar or seat pillar I attach a parallel motion moveable in a longi-
tudinal direction and to this parallel motion attach the saddle instead of directly
to the saddle bar or seat pillar.
Various constructions of parallel motions may be used to carry my invention
into effect.
For example, one construction which I use is similar to the well known parallel
ruler having two parallel bars joined by link bars which are at right angles to the
parallel bars when the same are furthest apart. The upper of the two bars is
inoveable longitudinally and to this bar the saddle is fixed. Or the upper and
Prive 71

page_text: moveable bar of the required parallel motion to which the saddle is to be attached
may slide upon roller or other bearings on the lower or fixed bar.
In all cases the moveable bar carrying the saddle may be fixed in the required
backward or forward position by a cam, screw, wedge or other suitable fastening to
prevent movement of the saddle when adjusted.
By means of my invention a rider can move his saddle backwards or forwards
as required by the nature of the road without dismounting from his machine.
The accompanying drawings shew several forms of my invention.
Fig. I shews a parallel motion fitted to the horizontal part of the seat pillar a.
The saddle is carried by the bar b, which is moveable backwards and forwards by
the parallel motion provided for by the links c and d.
Fig. II shews a modification of Fig. 1. The parallel motion e, f, g, h is complete
in itself and adjustable on the seat pillar by means of the screw i.
Fig. III shews a form of solid link which may be used in place of two links
.at c d
g or h in Figs. I and II.
:
Fig. IV shews a catch to secure the parallel motion when it is in the required
backward or forward position. The catch o hinged on the seat spring p clips the
seat pillar a and thus prevents the seat rising. When it is required to alter the
seat the catch is released by taking hold of the comb q and pulling it in an outward
direction.
Figs. V and VI shew another form of my invention. On the seat pillar a the
sliding piece j can be moved as required to adjust the saddle backwards or forwards.
The rollers kk give freedom of motion and the cam / fixes the sliding piece when
j
adjusted. The stops m prevent the sliding piece from travelling too far. Fig. VI
shews an end section of this form.
Figs. VII and VIII shew a form of my invention which differs from Figs. V
and VI in having no rollers under the sliding piece n. A cam for tightening may
be used as in Figs. V and VI. Fig. VIII is an end view of this form.
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. The adjustable mount for cycle saddles shewn by Fig. I of the drawings.
2. The adjustable mount for cycle saddles shewn by Fig. II of the drawings.
3. The adjustable mount for cycle saddles shewn by Figs. V and VI of the
drawings.
4. The adjustable mount for cycle saddles shewn by Figs. VII and VIII of
the drawings.
5. Adjustable mounts for cycle saddles having a parallel adjustable motion
backwards and forwards, with or without cams or locking catches.
