COMPLETE SPECIFICATION.
Improvements in Spring Seats or Saddles for Cycles and other
Vehicles and Travelling Machines:
I, PAUL KÖHLER, of 45, Prenzlauer Allee 45, Berlin, in the Empire of Germany,
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 seat or saddle, springy in itself, for the
drivers of vehicles or travelling machines of any kind, and more particularly
for cyclists.
The invention consists essentially of a fixed frame of suitable form and a series
of flat springs supported by this frame, which are bent out above the frame
and then united to form a flat dome arching over the frame. This dome forms
the spring seat.
The frame is provided with a device for attaching it to the vehicle or machine.
The invention is shown in the accompanying drawings in which:-
Figure 1 is a plan view,
Figure 2 a view from beneath, and
Figure 3 a section on the line - of Figure 1 looked at in the direction
indicated by the arrow.
The frame serving as support for the series of flat springs consists of two
parts 1 and 2 covering one another, which receive between them the lower ends
of the flat springs and which are screwed or rivetted together and to the flat
springs.
The frame carries a plate 3, on which is fixed a clip or sleeve 4 having a screw 5
whereby it may be attached to any suitable part of a vehicle, machine or cycle.
The dome of flat springs consists on the one hand of a broad spring 6, and
on the other hand of narrow springs 7, 8, 9, 10, 11, 12, 13, 14, 15. In order to
allow the spring 6 to bend to correspond with the form of the frame 1, 2, this
saddle spring is divided into three flaps 18, 19, 20 by means of slits 16, 17 at the
end which is to be bent round. The broad flaps 18, 20 are preferably provided
with slits 21, 22 in order to obtain a better spring action. It is self evident that
instead of one broad spring 6, several narrow springs may be employed; however
it is preferable for the manufacture to employ a broad spring 6 as shown.
The spring 6 is connected with springs 7 to 15 by means of screws or rivets 23.
According to the thickness or kind of material employed for the springs, it may
be advisable to also arrange in addition to the springs 6 to 15, one or more sets
5 of inner springs as shown in Figures 2 and 3. Such a set of springs is indicated
by the numbers 24, 25, 26, 27, 28, 29, 30, 31, 32 and these springs lie under the
spring 6. In a similar manner, if necessary, inner springs may be arranged
under the springs 7 to 15, as represented in Figure 3, with respect to the
springs 7, 8, 9, 10, by the inner springs 33, 34, 35, 36. These springs are also
10 fixed at one end between the parts of the frame 1, 2, and connected at the other
end with one another by the screws or rivets 28.
Finally short stiffening springs, as shown in Figure 3 by the springs 37 and 38

page_text: may be inserted between the outer and the inner set of springs, in order if
necessary to stiffen the lower part of the set of springs, and to prevent a bulging
of the same to the outside beyond the frame 1. These springs 37 and 38 are
also fixed between the parts 1 and 2 of the frame.
The springs 37 and 38 may of course be employed without the inner springs 33,
34, 35, 36.
The invention is not limited to any special number of sets of springs, but it
is left to the expert to employ one or more sets of springs according to the object.
of the seat and the strength or kind of material employed.
The only essential point is the arrangement of one or more sets of flat springs
on a frame and the connection of the springs to form a flat dome bent over the
frame and projecting above the same.
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 is
A spring seat or saddle for vehicles or travelling machines and more particu-
larly for cycles, consisting of a frame with means for attaching it to the vehicle
and one or more sets of flat springs attached to said frame and so connected
together as to form a flat dome bulging out over and covering the frame sub-
stantially as herein before described."
