I, HERMANN RUPRECHT from Goettingen, 21 Düstere Eichen at Goettingen,
Germany, Referendary out of service and Candidate of Theology, do hereby
declare that the nature of my invention, and in what manner the same is to be
performed, is exactly described and ascertained in the following statement::
In the accompanying drawings
Fig. 1 and 3 are side views of the saddle, Fig. 2 and 4 plan views of the
underframe and the springs. The saddle is exhibited as loaded with the springs
compressed by a middling pressure.
Fig. 5-14 are views on an enlarged scale comparatively to Fig. 1-4, of details
relating to the attachment of the springs to the saddle frames. Fig. 5-10, 12 and
13 are side views, Fig. 11 and 14 are plan views.
Like letters of reference indicate like parts throughout the several figures.
I describe my saddle with reference to the drawings as follows.
1. A line or leather strap or thin metal band or any flexible connection, E, leads
from the rear part or the midet part of the upper frame of the saddle to the front
part of the underframe or, if there is no underframe of usual form but a particular
underframe for the foresprings, to this particular underframe of the foresprings.
This connection prevents the spiral springs or other springs by means of which the
saddle mounted, from bending backward, a thing that must otherwise occur,
since the forward movement of the machine must be transferred by means of the
springs to the upperframe, the seat and the riders body. Upon the occurrence of
shocks the connection, because it is flexible, renders the saddle capable of sliding
to a slight extent forward with the rider. Since the connection swings in.the
vertical plane correspondingly to the upward and downward motion of the upper-
frame, its ends may be attached by means of movable links, or, if the connection
consists of a line or leather strap, it may as shown in the drawings bend and turn
round a pivot-pin P or round any convenient part of the frame, for example the
screw-knob P' in Fig. 1. It is advantageous to place the connection in that
manner that if the saddle is loaded and the springs are compressed by a middle
pressure, the connection stands perpendicular to the axes of the spiral springs as
shown in the drawings. Besides it must be placed in such manner that it does not
touch the seat or any other part of the saddle even though the springs are most
compressed. Therefore in the most cases it is impossible to fasten the connection
immediately to the front part of the underframe and to the rear part of the upper
frame, but there must be adjoined to the front end of the under frame an upward
or downwards extending rod, D, or the frame may be extended itself upwards or
downwards as shown in the drawings, and to the rear part of the upper frame must
be adjoined a downwards extending piece, D.
2. The upper frame and the underframe of my saddle are extended (A and B)
and spiral springs C placed between them. The frames may be extended
themselves, as in the drawings, or particular extending rods may be applied to
them. Instead of an extended underframe, there may be a particular underframe
for the foresprings. The leathern seat, F, may keep its usual length, as in the
drawings, or may also be extended in order to cover wholly or partially the
extending rod or extended upper frame. The hitherto usual place for spiral

springs under the front end of a seat of usual length allows only the employment
of springs of small diameter, with regard to the riders legs. Now such springs of
small diameter, to be sufficiently elastic, must be made of correspondingly small
wire and therefore they are not capable of resisting the lateral pressure, sometimes
considerable, which in the movement of the riders legs is exerted alternately to the
right and to the left against the seat and the foresprings. Since the position under
the front end of a seat of usual length does not permit placing the spring high
relatively to the seat, the greatest power of the lateral pressure is exerted on the
under end of the spring. Consequently the spring must break at its lower end, and
experience proves that it does so.
Therefore the frames of my new saddle are extended in order to place spiral
springs occupying large transversal space out of reach of the riders legs. The
frames may be extended not only forward but also upwards and the springs placed
high relatively to the seat, as in the drawings, in order to protect better the lower
end of the springs against the mechanical effect of the above-said lateral pressure
and in order to leave on the shortest way that is by the least extension of the
frames that region where the riders legs do not allow the employment of springs
occupying large transversal space. The Figs. 1 and 2 are views of a saddle
mounted in the manner referred to by means of one forespring, C, of great diameter,
made of correspondingly large wire.
To gain full security against the breaking of the foresprings under all circum-
stances and for any length of time, a further improvement is necessary.
There
must be employed instead of one forespring a number of foresprings, disposed on
the right and on the left of the middle line of the saddle and thereby adapted to
resist the above-said lateral pressure. Commonly there will be employed two
*prings, juxtaposed. The foresprings thus disposed may be made of medium or
small wire with windings of correspondingly medium or small diameter. Fig. 4
and 5 are views of a saddle mounted in this manner by two springs, C and C¹,
juxtaposed.

inclined position, as shown in the figures, C, C₁, C, so that the seat of the rider is
carried forward, if the springs are compressed in the direction of their axes.
construction is possible since by the flexible connection E the springs are protected
from bending backward, and it is advisible, in as much as every shock retards
the machine, while the body of the rider tends to preserve its former velocity.
4. The springs in Fig. 1-4 are fixed in position in the manner hitherto usual, by
pins and nuts; they may also be fixed as shown in Fig. 5-14, by letting one of
their ends, G, provided with a slot or groove, H, or with a slope, T, into an eye
bracket, K, fixed on the saddle under frame or upper frame, and then locking the
slotted or sloped end of the spring with a locking plate L, fixed in the eye bracket
by screws or rivets; or the eye in the bracket may be made of a taper or conical
form, N, and the correspondingly tapered end of the spring, M, seated therein.
I claim:
1. In a spring saddle for velocipedes, especially in a saddle mounted by means of
spiral springs the employment of a flexible connection leading from the middle or
rear part of the upper frame to the front part of the under frame or to a particular
under frame of the foresprings.
2. In a spring saddle for velocipedes, especially in a saddle mounted by means of
spiral springs the employment of a flexible connection as claimed in 1, placed in
such position as to stand perpendicular to the axes of the springs, if the seat and
the upper frame are pressed down by a middling pressure.
3. In a spring saddle for velocipedes, especially in a saddle mounted by means of
spiral springs the employment of a flexible connection as claimed in 1˚ placed in

frame.
5. In a spring saddle for velocipedes a forwards or forwards and upwards extended
upper frame and a correspondingly extended under frame and spiral springs fixed

6. In a spring saddle for velocipedes the employment of a number of spiral
foresprings disposed on the right and on the left of the middle line of the saddle,
especially the employment of two juxtaposed spiral foresprings.

an extended upper frame and a correspondingly extended under frame as claimed
