PROVISIONAL SPECIFICATION.
An Improved Saddle for Velocipedes.
I LEONARD POILVACHE, of 27 Rue Nysten, Liége, in the Kingdom of Belgium,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved saddle for velocipedes and I hereinafter
describe under the name of saddle the metal part, skeleton, or frame upon which
rests the actual seat of the velocipedist. This seat is fixed upon the upper plate of
the saddle, and this latter is fitted, as usual, upon the tube of the velocipede by the
id of screw nuts.

Figure 4 a view of the washer serving to secure the outer spiral spring;
Figures 5 and 6 show the springs previous to their application to the saddle, that
is to Бау at rest.
My improved saddle for velocipedes is composed of two metal plates a and b of
suitable shape, united by three or more pairs of spiral springs, c and d. The last
spire c' of the springs c is straightened and sufficiently narrow not to permit the
head g of the connecting bolts h to pass through it.
Each pair of spiral springs c and d is composed of a traction spring c and a
compression spring d (Figures 5 and 6).
The two springs c and d, which compose each pair of springs have their spires
turned in inverse direction, and, for two pairs of springs placed facing each other or
side by side (like the two pairs of springs on the left Figure 1), the spires of the
springs of a same kind (thus the spires of the two springs and those of the two
springs d) are preferably turned in inverse direction (see Figure 2). These arrange-
ments of the spiral springs ensure to the saddle great stability against any displace-
ment or lateral oscillation.
The two springs c and d, are preferably arranged concentrically, and are each
fixed by their ends with the aid of the discs fand the heads g of the nut bolts h
which fix the springs to the metal plates a, and b, respectively. A disc f is introduced
into the last spire at each end of the springs d, and the bolts h, placed in the springs o
and the head of which is held by the last straightened spire of these springs, pass
through the discs fand the plates a, b, respectively, fix the two springs on the
plates a and b and thus connect these latter.
Each pair of springs being composed of a traction spring c and a compression
spring d, the result is that these springs exert upon each other a compression
respectively a traction determined by the respective power of the spring acting in
inverse direction.

Thus, the traction spring e is stretched by the effort exerted against it by the
compression spring d, whereas this latter is compressed by the action of the traction
spring c. Therefore the two plates a and b are submitted vertically to contrary
traction forces.
Any shock produced on the wheel or wheels of the velocipede, in meeting any
kind of obstacle, passes to the plates a and b and consequently on to the springs
and d. This shock in acting with equal force upon each of the springs c and d gives
them only alight oscillations which are at once abolished by the contrary action

shocks.
COMPLETE SPECIFICATION.
An Improved Saddle for Velocipedes.
I LÉONARD POILVACHE, of 27 Rue Nysten, Liége, in the Kingdom of Belgium,
Manufacturer, 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 relates to an improved saddle for velocipedes and I hereinafter
describe under the name of saddle the metal part, skeleton, or frame upon which
rests the actual seat of the velocipedist. This seat is fixed upon the upper plate of
the saddle, and this latter is fitted, as usual, upon the tube of the velocipede by the
aid of screw. nuts.
On the drawing left with the Provisional Specification :
Figure 1 is a top plan view of my saddle;
Figure 2 a side view ;
Figure 3 a longitudinal section at A B ;
--
Figure 4 a. view of the washer serving to secure the outer spiral spring į
Figures 5 and 6 show the springs previous to their application to the saddle, that
is to say at rest.
My improved saddle for velocipedes is composed of two metal plates, a and b, of
suitable shape, united by three or more pairs of spiral springs, c and d. The last
spire c¹ of the springs c is straightened and sufficiently narrow not to permit the
head g of the connecting bolts h to pass through it.
Each pair of spiral springs c and d is composed of a traction spring c and a
compression spring d (Figures 5 and 6).
The two springs c and d, which compose each pair of springs have their spires
turned in inverse direction, and, for two pairs of springs placed facing each other
or side by side (like the two pairs of springs on the left Figure 1) the spires of the
springs of a same kind (thus the spires of the two springs c and those of the two
springs d) are preferably turned in inverse direction (see Figure 2). These
arrangements of the spiral springs ensure to the saddle great stability against any
displacement or lateral oscillation.
-
The two springs c and d are preferably arranged concentrically, and are each
fixed by their ends with the aid of the discs and the heads g of the nut bolta h
which fix the springs to the metal plates a, and b, respectively. A disc is introduced
into the last spire at each end of the springs d, and the bolts h, placed in the
springs c and the head g of which is held by the last straightened spire of these
springs, pass through the discs fand the plates a, b, respectively, fix the two springs
on the plates a and b and thus connect these latter.
Each pair of springs being composed of a traction spring c and a compression
spring d, the result is that these springs exert upon each other a compression respec-
tively a traction determined by the respective power of the spring acting in inverse
direction.
Thus, the traction spring c is stretched by the effort exerted against it by the
compression spring d, whereas this latter is compressed by the action of the traction
spring c. Therefore the two plates a and b are submitted vertically to contrary
traction forces.

page_text: and d
Any shock produced on the wheel or wheels of the velocipede, in meeting any
kind of obstacle, passes to the plates a and b and consequently on to the springs c
and d. This shock in acting with equal force upon each of the springs
gives them only slight oscillations which are at once abolished by the contrary
action of these two springs. The result is that the velocipedist scarcely perceives
these shocks or jars.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what 1
claim is :-
A saddle for velocipedes the plates a and b of the frame of which are connected
by traction springs d and compression springs c arranged side by side or one above
the other, for the purpose of deadening shocks or jars.
