Improvements in Spring Tension Saddles for Velocipedes.

Manufacturer do hereby declare the nature of this invention to be as follows:-
A. saddle constructed according to this invention has bottom frame with two or
more leaves or layers of metal.
The said leaves or layers are bracketed central. At a distance from middle
they divide. The inside leaf or layer is of the strongest proportion and may be
made of hue or other shape, and is curved at each end to stand about midway
between bottom frame and saddle trees. And is to form a butment for spring
tension. The spring may be made of rubber or steel. When of steel it may be a
spiral or a flat coiled spring.
The bottom leaves or layers of the said bottom frame are curved in a larger
circle and extend to the saddle trees, and may be fixed rigidly to said saddle trees
or connected by draught springs in a horizontal angle. The said draught springs
may be rubber or spiral springs. The said tension springs are fixed about midway
of the outside circle. By this arrangement I place the said rubber spiral or flat
coiled spring in an horizontal angle. The adjustment bolts or set pins may be
attached to the outside or inside said leaves or layers of metal. The said bolts or
set pins are to keep in a rigid position, and to give tension to the said rubber
spiral or flat coiled springs, which are fixed between said leaves or layers of metal
at each end of the saddle. By this arrangement 'I get the tension from the springs
which carry the rider. This arrangement of spring tension at each end of the
saddle is applied to spiral or rubber springs used in perpendicular as well as
horizontal angles. When applied to spiral or rubber springs in a perpendicular
angle, the said inside leaf or layer of metal extends in a line with saddle trees, and
is to form a butment for spiral or rubber draught springs. The said draught
springs are used to give tension to the saddle. In this case the said bottom leaf or
layer is not curved. The said saddle trees are connected by a light steel spring
which carries a rubber buffer which sustains and gives spring to the top of the
saddle.

Improvements in Spring Tension Saddles for Velocipedes.
1, JOHN AYLWARD, of 5 London Road, Coventry in the County of Warwick,
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
In order that my invention may be readily understood, I will describe it with
reference to the accompanying drawings, of which
=
Figure 1 is a longitudinal section through the centre of a velocipede saddle with
my improvements applied thereto;
Figure 2 is a view of the underside of the saddle;
Figure 3 is a vertical section on line of Figure 1
Figure 4 is a vertical section on line yy of Figure 1
Figure 5 is a section taken on line of Figure
and

page_text: Figure 6 is a detached front elevation of the bracket by which the saddle is
fixed to the L-pillar, and shews in section a portion of the frame passing
therethrough.
The leather portion, or seat proper, A is riveted to metal trees a and b as usual;
and according to my invention; these trees are supported by a frame consisting of
two leaves or layers kc. Each leaf or layer of the frame is formed in one piece of
metal bent over at k¹ c', respectively, to form it into a double-sided frame. Each
side of the frame k is bent down to form it into a spring; and each side of the
frame c has formed therein flat coils c² 3 and 4, to give it the necessary elasticity
or tension. The hinder ends of both the frames, that is to say, the hinder ends of
the compound frame, are fixed to the hinder tree b, by means of screw bolts i
passing through the tree and through eyes formed by bending round the
unconnected ends of the metal forming the frames, or in other convenient manner.
The heads of the bolts i lie in recesses dished down in the metal of the tree,
as shewn in sectional view Figure 5. The forward ends of the compound frame kc
are attached to the front tree a by means of a bolt which passes through loops
formed, respectively, by the bends k¹c, and through a loop or eye e formed of
bent sheet metal riveted into the hollow of the trec. A transverse section of this
loop, in position within the tree a, is shown by Figure 4. The bolt has a hexagon
head at the front end which is consequently easily accessible for use in tightening
up.the bolt by means of a spanner, and the bolt has a nut g at its inner end which
is shaped along its upper side to fit against the underside of a part h of the tree a
and thus prevent it being turned as the bolt is turned. The front ends of the
frames thus form an abutment for the spring tension; and the tension of the
frames is readily adjusted by turning the bolt d by means of the head fat
the front; and it will be observed that the tension end ways of the seat is derived
from the springs which carry the rider, that is to say from the spring frames e
and . The method of connection between the tree a and the forward ends of the
frames he allows the forward end of the seat to rock on an axis which is very-little
below it, that is to say, on the axis of the bolt d, which is found to be a great
convenience in riding. The bolt d, instead of having a nut g, may be screwed into
a block fixed to the tree a in place of the eye e, or into a block formed with a
wrought or cast metal tree; or the nut may, of course, be on the forward end of
the bolt. If the saddle is not needed for supporting a heavy man, the frame k may
be dispensed with; and this frame may at any time be readily removed by simply
unscrewing the bolt d and the nuts of the bolts i.
:
The bracket B is formed, as shewn, to clip both sides of the frame c. The
horizontal member of the L-pillar is passed also through the bracket and, to fix
the parts together, the set pin is tightened up and jams the L-pillars tightly
against the sides of the frame. The sides of the frame e slant downwards towards
the middle, as shewn by Figure 1, and thus, by moving the bracket along the
frame into the necessary position before fixing it to the L-pillar, any desired
inclination may be given to the saddle when fixed. In the mid-position in which
the bracket is shewn by Figure 1 the saddle will be fixed horizontally. A
transverse key, with a nut on the end, similar to the transverse keys used for fixing
cranks on the axles of velocipedes, or other suitable device, may be used in lieu of
the set-pin l.
.
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 I
claim is :-
1 The improved spring tension saddle for a velocipede, constructed substantially
as described.*
2. In a spring tension saddle for a velocipede, the compound frame kc, consisting
of the frames kc each formed in one piece of. metal, connected with. the front tree
substantially in the manner described and shewn.
3. In a spring tension saddle for a velocipede, the double-sided spring frame c

page_text: formed in one piece of metal, and connected with the front tree substantially in the
manner described and shewn.
4. In a spring tension saddle for a velocipede, the means of connection between
the front tree and the forward end of the supporting frame, whereby the forward
end of the seat or top of the saddle may rock on an axis very close below it,
substantially as described and shown.
5. In a spring tension saddle for a velocipede, the forward tree connected with
the forward end of the supporting frame by means of a bolt having a head on its
outer or forward end by which it may be turned by means of a spanner and a nut
or corresponding part on its inner end which is prevented, from turning, substan-
tially as described and shewn for the purpose set forth; and also the alternative
arrangement described in which the nut is on the forward end of the bolt.
6. In a spring tension saddle for a velocipede, in which the seat or top is
supported by a spring frame, a bracket B through which a portion of the frame
and also the horizontal member of the L-pillar passes, and means by which the
L-pillar is jammed against the frame, substantially as described for the purpose set
forth.
