FRITZ CARL HERMANN KLARE of 16 Lärmberg, Wandsbek-Hamburg, Gormany,
Forwarding Merchant, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object a contrivance for retaining constant, irrespective
of the weight the distance between the saddle, and the pedals on such cycles as
have a spring arranged for carrying the saddle, as substitute for the pneumatic
tires.
On the drawing,
Fig. 1 shews a side view of the contrivance, partly, in section.
Fig. 2 a front view, partly in section.
The saddle a is fastened on the right angled rod b, by which it can be fixed at
any desired height in the tube c. The upper part of the tube c is inserted into the
frame d, and its lower part into the cross-piece e, by means of the rod bent
forwards below the latter. Around the tube c a strong spiral spring g is placed, the
lower end of which presses against the plate à resting on the cross-piece e, and the
upper end against the plate . The latter buts against the nut i, which can be
screwed up and down on the tube c, which is here provided with a thread, in order
This
to give the spring a tension in proportion to the weight on the saddle a.
spring g serves for taking up the jolting, and renders pneumatic tyres superfluous.
The forwardly bent angle-arm of the rod f, is, by means of a bolt & linked to
the like operating levers 1. The points of support of these levers are formed by
the bolts mm' of the arms n n fastened on the frame A, whilst the bolts oo lie in

forms at the same time the fulcrum for the treadle levers rr'. The ratio of the
free longer arm to the short arm of each of these treadlo levers is likewise

It is therefore obvious that with any weight operating on the saddle, in consequence

HIPPERLING of 44, Bargenstrasse, Wandsbek-Hamburg, Germany, Manufacturer and
FRITZ CARL HERMANN KLARB of 16, Lärmberg, Wandsbek-Hamburg, Germany,
Forwarding Merchant, 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 has for its object a contrivance for retaining constant irrespective
of the weight the distance between the saddle and the pedals on such cycles as
have a spring arranged for carrying the saddle as substitute for the pneumatic
tires.
On the drawing filed with the Provisional Specification, Fig. 1 shows a side view
of the contrivance. partly in section, Fig. 2 a front view, partly in section.
The saddle a is fastened on the right angled rod b by which it can be fixed at any
desired height in the tube c. The upper part of the tube c is inserted into the
frame d, and its lower part into the cross-piece e, by means of the rod bent
forwards below the latter. Around the tube c a strong spiral spring 9 is placed,
the lower end of which presses against the plate h resting on the cross-piece, and
the upper end against the plate. The lattor buts against the nut i, which can be
screwed up and down on the tube c, which is here provided with a thread, in order
to give the spring tension in proportion to the weight on the saddle a. This
spring g serves for taking up the jolting, and renders pneumatic tyres superfluous.

The forwardly bent angle-arm of the rod f is, by means of a bolt k linked to
the like operating levers 11. The points of support of these levers are formed by
the bolts m m of the arms n n fastened on the frame A, whilst the bolts 00 lie in
such manner between the bolts m m and the common bolt k, that mo -forms a proper
fraction; that is mo must be shorter than ok. The bolts o of the levers 11 are linked
with the common bolt y lying in the slots p in the guiding frame u. This bolt
forms at the same timo the fulcrum for the treadle levers rr. The ratio of the
free longer arm to the short arm of each of these treadle levers is likewise
ok
It is therefore obvious that with any weight operating on the saddle, in consequence
of the above described lever-transmission the distance between the saddle a and
pedal always remains the same. The shorter lever arm of the treadle lever r
(or) is connected in any known manner with the crank I, which is mounted on the
shaft w of the chain wheel v.
om
Having now particularly described and ascertained the nature of our inven
tion, and in what manner the same is to be performed, we declare that, what we
claim is :
1. In a contrivance for retaining constant the distance between the saddle and
the pedals of cycles the combination of the two levers linked to the saddle rod
with the bolt k, the spring 9, the stationary bolt m, on which the levers II are
turning, the bolts o, the connecting rods w, the bolt q, which on yielding of the
saddle a, yields as much as the bolts o, so that as the lever arms of the lever / have

page_text: the same proportion as the treadle lever arms, the pedal s always remains equidistant
from the saddle as described.
2. The combination of nut i, spring g, plate h' and tube cas set forth.
