Improvements in Cycle Saddle Frames.
We, THOMAS MIDDLEMORE, trading as William Middlemore, of 101 Holloway
Head, in the City of Birmingham, Manufacturer, and WALTER ALBERT
DE LATTRE, of 70 Howard Street, Coventry, in the County of Warwick,
Commercial Traveller, do hereby declare the nature of this invention to be as
follows:-
Our invention relates to a special construction and arrangement of cycle saddle
tension bar and spring frame and its object is to permit of greater freedom of spring
action while securing the saddle firmly stretched by a tension bar.
In carrying the invention into effect we arrange a saddle with a cantle plate and
peak plate or eye. We stretch the saddle by means of a tension bar preferably of
round steel attached to the cantle plate by a stud and nut and passing through an
eye in the peak plate at the other end. The portion passing through the said eye
is screwed and carries a nut which nut serves to adjust the tension of the saddle
stretching it firmly on the tension bar. To the cantle plate we attach two springs
or wire frames one on each side of the tension bar each of which springs or wire
frames we preferably arrange with two coils. We attach each spring by a bolt or
stud and nut to the cantle plate and connect the front ends of the springs to a
sliding piece or shackle sliding upon the front part of the tension bar. The front
ends of the springs are preferably looped and pass over pins on the sliding piece,
on which pins they are secured by suitable washers and riveting or other convenient
device.
The back ends of the springs may also be attached by loops and studs to the
cantle plate.
By this arrangement we produce a saddle of which the leather may be stretched
to any desired degree of tightness and the springs or wire frames yet have free play
by means of the sliding block.
We thus combine a suitable degree of tension in the saddle with elasticity in the
spring supports.
The saddle boss or clip is attached to the springs in any usual manner and holds
the saddle firmly to the L pin.
We sometimes insert a spiral spring between the sliding piece and a bend or
collar on the tension bar, so arranging the said spiral spring as to aid the back
springs or wire frames.

Improvements in Cycle Saddle Frames.
We, THOMAS MIDDLEMORE, trading as William Middlemore, of 101 Holloway

DE LATTRE of 70 Howard Street, Coventry, in the County of Warwick,
Commercial Traveller, do hereby declare the nature of this invention and in what
Price R71

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
Our invention relates to a special construction and arrangement of cycle saddle
tension bar and spring frame, and its object is to permit of greater freedom of
spring action while securing the saddle firmly stretched by a tension bar.
Referring to the accompanying sheet of drawings
:-
Figure 1 is a longitudinal section of our improved saddle.
Figure 2 is an elevation.
Figure 3 is a reverse plan, and
Figure 4 is an end view on a larger scale of the sliding piece.
In carrying the invention into effect we arrange a saddle as A, with a cantle
plate B, and peak plate or eye C. We stretch the saddle A by means of a tension
bar D preferably of round steel, attached to the cantle plate B by a stud and nut
and passing through an eye in the peak plate C at the other end. The portion
passing through the said eye is screwed and carries a nut D', which nut serves to
adjust the tension of the saddle A, stretching it firmly on the tension bar D. To
the cantle plate B we attach two springs or wire frames E, one on each side of the
tension bar D, which springs or wire frames we preferably arrange each with two
coils as shown in Figures 1, 2 and 3. We attach each spring by a bolt or stud and
nut to the cantle plate, and connect the front ends of the springs E to a sliding
piece or shackle D' sliding upon the front part of the tension bar D. The front
ends of the springs are preferably looped and pass over pins D on the sliding
piece D³, on which pins they are secured by suitable washers D³, and riveting or
other convenient device. The back ends of the springs may also be attached by
loops and studs to the cantle plate.
.
By this arrangement we produce a saddle of which the leather A, may be
stretched to any desired degree of tightness and the springs or wire frames yet have
free play by means of the sliding block D'.
We thus combine a suitable degree of tension in the saddle with elasticity in the
spring supports.
The saddle boss or clip is attached to the springs in any usual manner and holds,
the saddle firmly to the L pin.
We sometimes insert a spiral spring between the sliding piece, and a bend.
or collar on the tension bar, so arranging the said spiral spring as to aid the back
springs or wire frames.
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. A cycle saddle frame in which the leather of the saddle may be strained to
any desired tension on a tension bar or like device, while the springs supporting the
saddle are attached at one end to a sliding block on the said tension bar or like
device, and at the other end to the cantle plate or other like part of the saddle, so
as to render the tension of the saddle independent of the elastic support, substantially
as herein before set forth.
2. The improved arrangement of tension bar and spring frame herein before
described, with reference to the accompanying sheet of drawings.
