I, WALTER RADERMACHER, of 200, Piccadilly, W., Company Manager, do here-
by declare the nature of this invention to be as follows:-
My invention relates to saddles for velocipedes, and has reference more particu-
larly although not exclusively to that class of cycle saddles that are longitudinally
divided along the centre; its objects being chiefly to support such saddles on a
cradle spring and afford means for adjusting or tightening each side of the saddle
independently of the other; and also, in the case of a divided saddle, to provide
means for adjusting or varying the distance of the two halves from each other.
According to my invention I attach the peak or point of the seat leather (or seat
leathers, in the case of a divided saddle) to a hook which engages with the loop
formed at the front end of a cradle spring in the ordinary manner. The back
or rear end of the leather (or leathers) is secured to a plate or plates, carrying
bosses to which the rear ends of the spring are secured. These ends are suitably
bent to pass through holes in said bosses, and terminate in a straight portion of
sufficient length to give the necessary adjustment. The ends fit the holes in the
bosses, and are screwthreaded, and the adjustment may be obtained by loose sleeves
and nuts on such screwed portions. The aforesaid bosses may be pivotally con-
nected to the aforesaid rear plates; but in the case of a divided saddle they are
firmly affixed to the rear plates or formed in a piece therewith, so as to enable
the said plates to be maintained in proper position through the rigidity of the
spring.
According to the second part of my invention I obtain adjustment of the width
of a divided saddle, or variation of the amount of separation of its halves by pro-
viding each of the back plates with a boss which is pivotally connected thereto,
and has a tapped hole therein, the hole in the boss on one side having a right hand
thread and that in the other a left hand thread. Into these holes is screwed a
right and left hand screw bolt, provided at its centre with a nut, or its equivalent,
by means of which it can be turned, and caused either to screw into the holes
in the pivoted bosses, thereby causing them to approach each other and decreasing
the width of the saddle; or to screw out of such bosses, thereby increasing the
width of the saddle, and therefore of the space between its halves.

page_text: I, WALTER RADERMACHER, formerly of 200, Piccadilly, but now of 86, New
Bond Street, in the County of London, Company Manager, do hereby declare the
nature of this invention and in what manner the same is to be performed, to he
particularly described and ascertained in and by the following statement:-
My invention relates to saddles for velocipedes, and has reference more particu-
larly although not exclusively to that class of cycle saddles that are longitudinally
divided along the centre; its objects being chiefly to afford means for adjusting
or tightening each side of the saddle independently of the other; and also, in the
case of a divided saddle, to provide means for adjusting or varying the distance
of the two halves from each other.
According to my invention, and when applying the same to a saddle supported
by a cradle spring, I attach the peak or point of the seat leathers to a hook which
engages with the loop formed at the front end of the cradle spring in the ordinary
manner. The back or rear ends of the leathers are secured to plates carrying
bosses to which the rear ends of the spring are secured. These ends are suitably
bent to pass through holes in said bosses and terminate in a straight portion of
sufficient length to give the necessary adjustment. The ends fit the holes in the
bosses, and are screw threaded, and the adjustment is obtained by nuts on such
screwed portions with or without loose sleeves between such nuts and the bosses.
The aforesaid bosses are firmly affixed to the rear plates, or formed in one piece
therewith, so as to enable the said plates to be maintained in proper position by
the rigidity of the spring.
I obtain the adjustment of the width of the saddle, or the variation of the amount
of separation of its halves, by providing a right and left hand screw threaded pin
or bolt which is connected with the aforesaid rear plates.
By turning the said screw threaded pin, the halves of the saddle are caused to
approach towards or recede from each other thereby regulating the width of the
saddle.
My invention is also applicable to a saddle supported on vertical spiral springs,
as will be hereinafter described.
In order that my invention may be clearly understood I will proceed to describe
the same more fully with reference to the accompanying drawings, in which:
Figures 1, 2, and 3 are, respectively, an underside view, a side elevation and a
rear elevation, of a saddle constructed according to my invention and provided
with a cradle spring or springs.
Figures 4, 5 and 6 are views similar to Figures 1, 2 and 3, of a saddle constructed
according to my invention and provided with vertical spiral springs
Figure 6 is a detail view hereinafter referred to.
In Figures 2 and 5 one half of the saddle is removed, and in Figure 4 a portion
of the under frame is removed, so as to more clearly show the arrangements of the
parts.
In all the figures like letters of reference indicate similar parts.
Referring first to Figures 1, 2 and 3, 6 is a cradle spring formed of a single
piece of steel wire suitably bent upon itself. On the limbs or members of this spring
is placed the clip d for securing the saddle to the saddle pin of the velocipede. A
hook a³, secured to the front end or peak of the saddle leathers a, engages with
the loop formed at the front end of the spring 6 in the ordinary manner.
Each of the saddle leathers a a is rivetted or otherwise secured at its rear end to
a separate segmental plate or crosspiece a¹, a¹. At or near the middle of each seg-
mental plate a¹ I provide a fixed boss a', preferably formed integrally with said

page_text: plate a¹. The rear ends of the spring b are bent over and pass through holes in
said bosses and terminate in a straight portion b¹ of sufficient length to give the
necessary adjustment. The ends of the spring fit the holes in the bosses a', and
are screw threaded, and provided with loose sleeves 62 and nuts by which the
independent adjustment of each half of the saddle is obtained. If desired however
I may dispense with the sleeves b².
Each of the plates a¹ also carries at or near its inner extremity a boss or block f
which is pivotally connected thereto and has a tapped hole therein. Into these
holes screws the right and left hand screw bolt f¹, so that by turning said bolt
I am enabled to adjust the width of the saddle or vary the distance between its
halves. The pivotal connection between the blocks f and the plates a¹ permits
the slight angular movement given to such plates when they are separated from
or approached toward each other, to take place without straining the bolt f¹.
In order to prevent the flaps a of the cover or scat leathers at the sides of the
peak from rising under the rider's weight and causing chafing, I provide a tie-
piece or connection, which may consist of a strip of metal or other suitable
material as, riveted or otherwise fastened at its extremities to said flaps.
b is
Referring now to Figures 4 to 6, each of the saddle leathers a, a, is secured
at its rear end to a separate segmental plate a¹, a', as described with reference to
Figures 1 to 3; but in this case each leather is at its front end also secured to a
separate plate a³, a³. 61, 61, are the rear spiral springs each of which is connected
to one or other of the plates a¹ by a bolt and nut or other convenient means.
the front spring and is similarly connected at its upper extremity to a block e.
At their lower extremities the springs b and b, bi are connected respectively to
the front and rear ends of a girder like under frame c, that may be formed of a
single piece or strip of flat steel, bent to the required shape and adapted to receive
the bolt d' of the clip d. A pair of suitably curved stretchers or frame wires a², 2*,
extend longitudinally slightly below and on each side of the opening between the
two seat leathers, and are secured, at their rear ends, one to each of the plates a¹, a'.
At their front ends these stretchers pass through closely fitting apertures in the
block e and are riveted one to each of the plates a³, a. These plates a³, q³ are
held in position between the jaws e* of the block e.
Each of the said longitudinal stretchers or frame wires is divided at a convenient
point in its length and the adjacent extremities are fitted in a sleeve g, g. The
extremity of the rear portion of the stretcher simply fits the rear portion of
the sleeve and abuts against an internal projection or stop gl provided therein. The
sleeve is therefore capable of revolving freely on the said extremity. The ex-
tremity of the front portion of the stretcher is screw threaded and engages an
internal thread in the front portion of the sleeve. Means are provided for enabling
the sleeve to be turned whereby the front portion of the stretcher may be screwed
into or out of the sleeve, and the tension of that half of the saddle corresponding
to such sleeve be thereby adjusted. Such means may consist for example in
forming a portion 2 of the sleeve of hexagonal shape so as to constitute a nut.
Instead of providing one portion only of the sleeve with a screw thread, I may
ferm a left hand thread in one portion and a right hand thread in the other, and
provide both the adjacent extremities of the longitudinal stretcher wire with corres-
ponding screw threads.
If however it be not required to adjust each half of the saddle independently of
the other I may dispense with the sleeves g, g*, and form each of the stretchers a³, a³¸
of a single length of wire. In such case both stretchers would be secured to the
block e, and both seat leathers would be riveted to a single plate a³ connected to
the block e by any well known tension device.
To the outer extremities of the plates al are secured stretchers or frame
wires a, a, arranged transversely of the saddle and with their ends overlapping
for a considerable distance. These ends pass through apertures in a pair of
blocks f, f, each of the ends passing through both blocks. Each of the longitud-
inal stretchers or frame wires a², a², also passes through one or the other of the

page_text: blocks f, f, in a direction at right angles to that of the frame wires a¹, a¹, as
shown.
In order that the blocks f, fx shall maintain a constant position upon the
wires a², a², and a, a, respectively, the longitudinal holes in the said blocks are
arranged to partially overlap or impinge upon the transverse holes so that à portion
of one or other of the wires of each pair must be cut away before both wires can
be passed through their respective block. The arrangement of these notches is
shown in Figure 6, which is an enlarged perspective view of that portion of the
four wires in and adjacent to the blocks. It will be seen that the wire a is notched
or has a portion cut away at a40* to receive the wire a whereby the block f* is
prevented from shifting upon the wire a**. The wire a is notched at a 20x to allow
the free ends of the wire a to slide over the same; whereby the block fis
prevented from shifting upon the wire a, but is free to slide to and fro on the said
end of wire a*. Similarly the wire a is notched at a to receive the wire a²,
and this wire a² is notched at a20 to receive the free end of wire at whereby a²
and at are fixed in position in the block ƒ while the said block is capable of sliding
to and fro on the wire a. An efficient connection between the frame wires is
thus obtained whereby the plates a¹ are maintained in their proper position for
supporting and stretching the seat leathers.
The double bolt fi engages the blocks f, f³, so that the width of the saddle, or
the distance between its halves, can be varied by turning said bolt and thereby
causing said blocks to move towards or away from each other, the overlapping ends
of the frame wires a, a serving as guides. To prevent such transverse lateral
adjustment unduly twisting the spiral springs 61, 61, these latter are arranged so
that when the parts are in their intermediate position the said springs are vertical.
As this transverse adjusting device projects somewhat below the cover or seat.
it might be liable to come in contact with the under frame when the springs
yield more than usual, and I therefore cause the parallel portions of this frame to
diverge before they come beneath said adjusting device, as clearly shown in
Figure 4. This construction enables the frame c to clear the adjusting device no
matter to what extent the springs may be compressed.
The arrangement of the piece or connection between the flaps a* is the same
as in the saddle described with reference to Figures 1, 2 and 3.
It will be readily seen that my improved tension devices, and means for pre-
venting the flaps a from rising, are applicable to saddles constructed without a
longitudinal opening; but in the case of such a saddle mounted on a cradle spring
I find it advisable in some cases to pivot the bosses a² to the back plate.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:-
1. A velocipede saddle provided with means for independently adjusting the
longitudinal tension of either half thereof, substantially as described.
2. A velocipede saddle provided with means for adjusting its width, substantially
as described.
3. A velocipede saddle constructed substantially as described with reference to
Figures 1 to 3, or Figures 4 to 64, of the accompanying drawings, and for the pur-
pose specified.
