PROVISIONAL SPECIFICATION.
Certain Improvements in and connected with Cycle Saddle Springs.
We, ALBERT EDWARD LOWENTHAL, of the Leatheries Limited, Nos. 1 and 2,
Cregoe Street, Holloway Head, in the City of Birmingham, Manufacturer, and
HENRY VINCENT, of Bath Street, Walsall, in the County of Stafford, Pattern
Maker, do hereby declare the nature of this invention to be as follows:-
This invention consists of the herein described improvements in and con-
nected with cycle saddle springs so as to make the said springs more resilient and
to facilitate the attachment of the said spring to the seat pillar or Ŀ piece and the
tilting and fixing of the saddle at any required angle.
Heretofore in cycle saddle springs those limbs or members of the spring which
are clamped to the central clip which fits on the seat pillar or L-piece, have been
made continuous and have passed between the parts of the clip which grip the
spring. In a cycle saddle spring constructed according to this invention the said
limbs of the spring which are attached to the clip are not continuous, that is to
say, the wire forming the spring is bent so as to form two pairs of spring side
arms which project inwardly towards each other from the ends of the spring and
at their said inner ends are formed as loops or eyes to turn on pins formed with
or connected to side plates or other parts to the said central clip so that the spring
arms can turn on these pins according to the weight on the saddle thus making
the spring more resilient than is the case when the said lower limbs of the spring
are made continuous as heretofore. The said pins are formed on two side plates
or bearers which are clamped to the clip and which can turn thereon and be fixed
at any required angle to suit the desired inclination of the seat. The end portions
of these plates or bearers are by preference continued outwardly beyond the two
pins on which the springs turn and these continuations are made with side pro-
jections forming stops for the spring arms to bear against when the spring is raised
to its highest position thus preventing the spring from lifting too high.
In order to secure the spring above described to the seat pillar or L-piece we
prefer to employ a clip which is constructed as follows and which clip forms one
part of this invention although it is to be understood that the improved spring
above described may be fitted to and used with clips of other kinds.
We provide a metal yoke which passes below the spring and is made with a
large central hole for the seat pillar to pass through. This yoke has two upwardly
projecting pins which are screw threaded and pass through holes in an upper
clamping plate which is made of somewhat similar shape to the yoke but without
the pins and has a large central hole for the seat pillar to pass through. Between
the said upper plate and the yoke there are two gripping blocks shaped to fit
against the seat pillar when the latter is threaded vertically through the holes in
the yoke and clamping plate and also made to fit against the said seat pillar
when passed between the clamping plate and yoke in a direction at right angles
to that above referred to. Each of these distance pieces is made with a side pro-
jection which is forked to fit against the upwardly turned pins of the yoke these

page_text: side projections forming pommels or trunnions on which are fitted the said side
plates or bearers to which the ends of the spring arms of the spring are jointed.
The upper surfaces of these two side plates or bearers are cross grooved and the
underside of the clamping plate is correspondingly cross grooved and shaped to
fit against the upper sides of the plates or bearers so that when the nuts on the
screwed pins of the yoke are screwed down tightly the yoke and clamping plate
will clamp the said plates or bearers of the spring tight on to the trunnions and also
force the distance blocks against the seat pillar thus fixing the clip to the seat
pillar and the spring to the clip. When it is desired to adjust the angle of the
saddle it is only necessary to slacken the two nuts on the ends of the pins of the
yoke when the seat and the spring and the side plates or bearers will all be free
to turn on the trunnions to adjust the saddle to the desired angle at which the
saddle can be fixed by tightening up the nuts on the pins of the yoke as above
described.
"The clip above described may be turned upside down and fixed in that position
to the spring if desired.

Certain Improvements in and connected with Cycle Saddle Springs.
We, ALBERT EDWARD LOWENTHAL, of the Leatheries Limited, Nos. 1 and 2,
Cregoe Street, Holloway Head, in the City of Birmingham, Manufacturer, and
HENRY VINCENT, of Bath Street, Walsall, in the County of Stafford, Pattern
Maker, 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 consists of the herein described improvements in and connected
with cycle saddle springs so as to make the said springs more resilient and to
facilitate the attachment of the said spring to the seat pillar or L-piece and the
tilting and fixing of the saddle at any required angle.
We will describe our invention by referring to the accompanying drawings on
which Fig. 1 is a side elevation of a cycle saddle spring and clip constructed
according to our invention; Fig. 2 is a plan of the same; Fig. 3 shews the spring
part separately; Fig. 4 is a cross section of the clip part on line X X of Figs. 1
and 2; Fig. 5 is a cross section of the spring and clip on line Y Y of Figs. 1 and 2;
Fig. shews the parts of the clip separately; Fig. 7 is a front elevation and
Fig. 8 is a side elevation of our said improved clip in use with an ordinary four-
wire spring frame of a cycle saddle; Fig. 9 shews the clip Figs. 7 and 8 with the
wires tilted; Fig. 10 is a front elevation and Fig. 11 is a side elevation of our
improved clip in use with another kind of cycle saddle underframe.
The same letters of reference indicate the same or corresponding parts in all
the figures of the drawings.
Heretofore in cycle saddle springs those limbs or members of the spring which
are clamped to the central clip which fits on the seat pillar or L-piece, have been
continuous and have passed between the parts of the clip which grip the spring.
In a cycle saddle spring constructed according to this invention the said limbs of
the spring which are attached to the clip are not continuous, that is to say, the
wire forming the spring is bent so as to form two pairs of spring side arms which
project inwardly towards each other from the ends of the spring and at their inner

page_text: ends are formed as loops or eyes to turn or pins formed with or connected to side
plates or other parts of the central clip so that the spring arms can turn on these
pins according to the weight of the saddle thus making the spring more resilient
than is the case when the said lower limbs of the spring are made continuous as
heretofore. By an examination of Figs. 1, 2 and 3 it will be seen that the ends
of the piece of wire A forming the back part of the saddle spring are formed as
eyes a¹² as usual to fix to the bolts of the curved back plate of the saddle and then
the wire after being coiled at a at is bent forward to form the lower wires a³ a
of the back pair of spring side arms and formed as eyes or loops a as to turn on
the pins of the two side plates 13 B2 of the central clip and then is bent
backwardly again to form the upper wires a 10 of the said back pair of side arms
the central part of the wire forming the cross bar a" crossing from the one spring
side arma to the other spring side arm a ao. The front pair of spring side
arms and the front part of the saddle spring are similarly formed of the piece of
wire the ends of which are fixed to the eye 1 through which passes the usual
adjusting screw at the peak of the saddle. The wire C then bends round and
forms the spring coil c¹² and then bends back to the clip forming the two
bottom wires c3 c4 of the front pair of spring side arms and then is bent round
and formed as eyes or loops 5c to turn on the other two pins 63 64 of the two side
plates B B of the central clip and then is bent forward again to form the upper
wires of the said front pair of spring side arms the central part of the wire
forming the cross bar crossing from the one spring side arm to the other
spring side arm 8. The two pins 61 63 are formed on the side plate or bearer B¹
and the other two pins 62 6 are formed on the other side plate or bearer B² which
plates B1 B2 are clamped to the clip as hereinafter described and can turn thereon
and be fixed at any required angle to suit the desired inclination of the seat.
The end portions of these plates or bearers 131 132 are by preference continued
outwardly beyond their two pins 662 and 63 on which the springs turn and
these continuations are made with side projections marked 65 66 67 68 forming stops
for the spring arms to bear against when the ends of the spring are by the tension
of the leather seat part of the saddle raised to their highest position thus preventing
the end parts of the spring from lifting too high.
In order to secure the spring above described to the seat pillar or L-piece we
prefer to employ a clip which is constructed as we will now describe and which
clip forms one part of this invention although it is to be understood that the
improved spring above described may be fitted to and used with clips of other
kinds. Our said improved clip is constructed as follows:-
We provide a metal yoke E which passes below the spring and is made with a
large central hole e' for the seat pillar to pass through. This yoke E has two
upwardly projecting pins e e³ which are screw threaded and pass through
holes ff in an upper clamping plate F which is made of somewhat similar shape
to the yoke E but without the pins and has a large central hole f for the seat
pillar to pass through. Between the upper plate F and the yoke E there are two
gripping blocks G¹ G² shaped at g₁ g² to fit against the seat pillar when the latter
is threaded vertically through the holes in the yoke E and clamping plate F and
also shaped at g³g to fit against the said seat pillar when passed between the
clamping plate F and yoke E in a direction at right angles to that above referred
to. Each of these distance pieces G1 G2 is made with a side projection g5 g which
is forked at g? 98 to fit against the upwardly turned pins e e³ of the yoke E these
side projections 95 g being rounded at the top and forming pommels or trunnions
on which are fitted the said side plates or bearers B1 B2 which are each made with
a rounded depression 610 underneath (see Fig. 10) to fit on the trunnions g³ gº.
The upper surfaces of these two side plates or bearers B₁ B3 are cross grooved and
the underside of the clamping plate F is correspondingly cross grooved at f* fo
and shaped to fit against the upper sides of the plates or bearers B1 B2 so that
when the nuts on the screwed pins ² of the yoke E are screwed down
tightly, the yoke E and clamping plate F will clamp the plate or bearers B¹ Bº of

page_text: the spring tight on to the trunnions g³g and also force the distance blocks G¹ G
against the seat pillar thus fixing the clip to the seat pillar and the spring to the
clip. When it is desired to adjust the angle of the saddle it is only necessary to
slacken the two nuts on the ends of the pins e² e³ of the yoke E when the
seat and the spring and the side plates or bearers B₁ B will all be free to turn on
the trunnions 95 go to adjust the saddle to the desired angle at which the saddle
can be fixed by tightening up the nuts h 2 on the pins e²e of the yoke E as
above described.
The clip above described may be turned upside down and fixed in that position
to the spring if desired.
When our
improved clip above described is used with an ordinary four wire
cycle saddle spring as shewn in Figs. 7, 8 and 9 the four wires marked i¹2 23 24
of the springs are located between the side plates or bearers 131 132 and the clamp-
ing blocks G G2, the said clamping plates being grooved at 6º to receive the wires.
When our improved clip above described is used with cycle springs of flat
section as in Figs. 10 and 11 the said flat section springs marked B³ B take the
place of the side plates or bearers BB2 and are each similarly made with a rounded
depression 610 to take on the trunnions gg and also made with a rounded notched
part to be gripped by the clamping plate F when the same is tightened up.
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 spring consisting of two wires which are bent to form the
back and front parts of the spring respectively and which have two pairs of spring
side arms projecting towards each other from the ends of the spring said arms
being formed as loops at their inner ends and connected together by side plates or
bearers adapted to be held by the central clip to the seat pillar, substantially as
herein before set forth.
2. The combination with a cycle saddle spring of the kind denoted under
Claim 1, of a stretched leather seat part secured to the back and front parts of
said spring so that the pressure of the rider on said seat causes the back and front
parts of the spring to turn on the pairs of side plates or bearers substantially as
described.
3. A cycle saddle spring consisting of the two wires A and C and the two side
plates or bearers B 12 said parts being formed and combined together in the
manner substantially as herein before described and illustrated by the accompany-
ing drawings and for the purposes set forth.
4. A cycle saddle spring clip consisting essentially of the combination of the
yoke E and end pins and nuts the two clamping blocks G1 G2 and the clamping
plate Fall constructed and arranged for use with the side plates or bearers BB
substantially as hereinbefore described and illustrated by Figs. 1 to 9 of the
accompanying drawings.
5. A cycle saddle spring clip consisting essentially of the combination of the
yoke E with end pins e²e and nuts the two clamping blocks G1 G2 and the
clamping plate F all constructed and arranged for use with the flat section saddle
spring sides B3 13 substantially as hereinbefore described and illustrated by
Figs. 10 and 11 of the accompanying drawings.
6. The improved combined cycle saddle spring and clip constructed and arranged
substantially as herein before described and illustrated by Figs. 1 to 6 of the
accompanying drawings.
