PROVISIONAL SPECIFICATION.
Improvements in Cycle Saddle Springs.
I, RUDOLPH CHARLES WILLIAM DUERRE of No. 446 Kings Road, Chelsea,
in the County of Middlesex, Watch and Clock Maker, do hereby declare the
nature of this invention to be as follows:-
My invention relates to improvements in cycle saddle springs and consists in a
novel construction or type of elliptical spring adapted for interposition between the
stalk and the saddle.
In carrying the invention into effect, I prepare a duplex elliptical spring, or
instead of being duplicated from end to end, each spring may be bifurcated..
Both duplication and bifurcation have a common object, riz. :-to provide equal
resilience on each side of the stalk or central plane of the cycle, so as to keep the
saddle steady and to prevent it being pulled to one side when the cycle is turning a
corner.
The several members of the spring may have as many plates as may be necessary
or desirable. The lower half of the ellipse is provided with suitable holding
devices adapted to hold it to the stalk or saddle post, the latter being modified
accordingly if necessary. A combination of a screw threaded pin fast to the centre
of each bottom member of the spring, a plate or tabs fast to the stalk or saddle
post, holes therein through which the said pins can be passed, and holding nuts,
constitutes a stable device for the purpose.
The bifurcated or duplicated ends of the spring are held together by bolts passed
through eyes in the way usual with springs. Distance pieces or tubes are interposed
between them, for the purpose of preventing friction there.
The saddle itself is fixed to the top member or members of the spring in any
suitable way.

Improvements in Oycle Saddle Springs.
I, RUDOLPH CHARLES WILLIAM DUERRE of No. 466 Kings Road, Chelsea,
in the County of Middlesex, Watch and Clock 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:-
My invention relates to improvements in cycle saddle springs and consists in a
novel construction or type of elliptical spring for interposition between the stalk
and the saddle.
The object of it is to provide equal resilience on each side of the central plane
of the cycle so as to keep the saddle stendy and prevent it from being pulled to one
side when the cycle is turning a corner. This object is attained by putting one of
the points of connection of the saddle frame to the respective spring, the spring
itself and the point of connection of the latter to the usual lateral extension of the

page_text: top of the stalk, immediately above or below each other, the points of connection
on one side of the said central plane being at the same distance from it as the
corresponding points on the other side.
Referring to the accompanying drawings which are to be taken as part of this
Specification and read therewith :-
Figure 1 is a side elevation of a bifurcated spring made according to my
invention, a saddle, and the top of the saddle stalk.
Figure 2 is a plan of the spring.
Figure 3 is a rear elevation of the spring and top of the stalk.
Figure 4 is a side elevation of a modified form of spring.
Figure 5 is a plan corresponding therewith.
Referring to Figures 1 to 3, a is the saddle aud b, the saddle stalk.
c, d are the two bifurcations of the spring. They both start from the rear ends
of the front portions of the spring and extend backwards therefrom till they meet,
where they are joined together by the usual bolt f. The front portions e are joined
together by the usual bolt g.
Instead of using an elliptical spring bifurcated in the manner specified, I may
use a pair of elliptical springs, one spring on each side of the central plane of the
cycle just as the bifurcations illustrated have each one leg on each side of the said
plane. I prefer a bifurcated elliptical instead of a duplicated elliptical spring
because the front portions e of the former stand, the one above the other, and both
centrally under the pommel of the saddle and, for that reason, out of the way of
the rider's knickers.
The top and bottom bifurcations are shewn as double plated, but the number of
plates is a detail which does not belong to the present invention.
The saddle a 18 shewn as held to the bifurcation e by a clamp consisting of a
tranevorse bar fast to the saddle frame and adapted to rest upon the said
bifurcation, a nutted screw pin h' depending centrally from the bar h, and a second
transverse bar adapted to stand on the opposite side of the bifurcation and
opposite to the first mentioned bar. The two bars h, h³ grip the bifurcation c,
or the top halves of the two springs, as the case may be, between them, when
the nut is screwed home on the piu . Any other means of holding the saddle to
the bifurcation c may be made use of. The bifurcation d, or bottom halves of the
two springs, as the case may be, is made fast to the saddle stalk by being bolted
to the ends of a lateral extension of the stalk top, as illustrated in Figure 3. Any
other suitable means for holding this part of the invention to the stalk top may be
made use of
The modification illustrated in Figures 4 and 5 relates only to the ends of the
spring. Instead of being bolted duectly to each other by the bolts f, g, as illustrated
in the preceding figures, the ends of the top half are curved downwards and inwards
and connected to the respective ends of the bottom half by means of shackles and
bolts f', g'.
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 18:-
The herenbefore described combination with saddle frame and saddle stalk, of a
duplented
bifurcated elliptical spring.
