PROVISIONAL SPECIFICATION.
Improvements in or Additions to Cycle Saddles.
I, JOHN BOULTBEE BROOKS, of Great Charles Street, in the City of
Birmingham, Manufacturer, do hereby declare the nature of this invention to be
as follows:-
My invention relates to improvements in, or additions to cycle saddles.
My present invention has reference in the first part, to a pneumatic mounting for,
or means for supporting, the seats of cycle saddles; in the 'second part, 'to the
metallic rod or wire under supporting framings of cycle saddles; and in the third
part; to a means for connecting the tension device to the framing.
.:
In carrying out the first part of my invention; the seat of a saddle is slung
hammockwise between the end 'supports of a metallic framing, fitted with a tensioning
device and other necessary adjuncts. The said thetallic framing, with the seat,
is supported at points, or at the front and rear ends, by or upon pneumatic pillars
or supports, each fitted at top and bottom with metallic caps or pressure plates,
which connect the said supports to the framings. These pneumatic supports, which
are, in themselves, air chambers, are each in communication with a common
distensible relief chamber, whose elastic walls are. thinner than the walls of the
supports, so that as air is displaced from one or both of the said pneumatic supports,
it enters the reserve chamber, which then, by its elastic walls, expands propor-
tionally, and thus the redundant air from the supports, which would otherwise take
away their resiliency, is temporarily stored; until pressure has been relieved, when
the walls of the relief chamber contract and the air returns. to the supports,
which are carried by a base framing connected to the seat pillar or' L pin of a
machine.
Instead of the whole of the supports having a common relief chamber, each
support'may have its own 'relief:
:
By dispensing with metallic connections and mounting the seats in the way
described, they are resiliently supported, and tremor or vibration is neutralized.
In a modified form of this part of my, invention, I locate the elastic reserve
chamber between the pillar and the underside of the seat, whilst the connection
between the seat and the pneumatic pillar is made by upright screws or equivalents,
which form surrounding posts for connecting the metallic part of the seat and the
pneumatic pillar together.
In carrying out the second part of my invention, I make the rod or wire métallic
underframings, and their springs, and also the metallic supporting'springs of saddles,
from twisted T, +, H, square, triangular or star sectioned wire or metal.
By making the framings and springs from metal of the section described, great
strength, combined with lightness, is acquired.
In carrying out the third part of my invention, the inner end of the tensioning
screw pin, whose outer end is beaded, passes through a screw nut located at the
back of a rubber cushioning block, carried by a box bracket secured to the front
anderside of the saddle seat.
"
:
The front returned end of the supporting framing, passes. transversely through
the arched inner part of an inverted U or staple-shaped bracket connection or
coupling, threaded upon the stem of the tensioning pin, prior to its inner end
being passed through the nut.

page_text: Instead of the inner end of the tensioning screw passing through a rubber
block, it may pass through a screwed eye in a hanging bracket.
By mounting the ends in the way described, the parts to be turned for adjustment
are made more accessible.

Improvements in or Additions to Cycle Saddles.
I, JOHN BOULTBEE BROOKS of Great Charles Street, in the City of
Birmingham, 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 :-
My invention has reference, in the first part, to a pneumatic mounting for or
means for supporting, the seats of cycle saddles which is a development of the
invention described in the Specification of my Letters Patent dated 26th day of
October 1893 No. 20195; and in the second part, to the metallic rod or wire under
supporting framings of cycle saddles which part is an improvement upon the
invention described in the Specification of my Letters Patent dated October 5th
1892 No. 17737.
In carrying out the first part of my invention, the seat of a saddle is slung
hammockwise between the end supports of a metallic framing, fitted with a
tensioning device and other necessary adjuncts. The said metallic framing, with
the sent, is supported at points, or at the front and rear ends, by or upon
pneumatic pillars or supports, each fitted at top and bottom with metallic caps
or pressure plates, which connect the said supports to the framings. These
pueumatic supports; which are in themselves, air chambers, are each in com-
munication with a common distensible relief chamber, whose elastic walls are
thinner than the walls of the supports, so that as air is displaced from one or
both of the said pueumatic supports, it enters the reserve chamber, which then,
by its elastic walls, expands proportionally, and thus the redundant air from the
supports, which would otherwise take away their resiliency, is temporally stored,
until pressure has been relieved, when the walls of the relief chamber contract
and the air returns to the supports, which are carried by a base framing connected
to the seat pillar or L pin of a machine.
Instead of the whole of the supports having a common relief chamber, each
support may have its own relief.
By dispensing with metallic connections and mounting the seats in the way
described, they are resiliently supported, and tremor or vibration is neutralized.
Figure of the accompanying drawings represents partly in elevation and
partly in vertical section, a cycle saddle, whose seat, with its under framing, is
supported upon fore and aft pneumatic pillars or supports, properly restrained
from distension by canvas or other. plys, and with the said pneumatic supports
being connected together by, or in communication with an unrestrained elastic
relief chamber, into which redundant air from either or both of the pneumatic
supports enters on pressure being applied to the said supports.
Figure 2 represents a plan of the said saddle supports and relief chamber
separately, with the seat shown in dotted lines.
a and b are pneumatic supports or cushioning pillars, having air chambers a¹, b¹,
within them, and with the walls restrained by canvas or other plys, and with the
crowns and bases of the same connected respectively to the seat under-framing c and
base framing d, by plates or metallic caps e, which take upon the flanged ends of

page_text: the said supports. Coming between, and being in communication with the said
supports, is an unrestrained elastic relief chamber f, capable of expanding and
contracting proportionally in accordance with the pressure of the redundant air
forced into it. One of the chambers is provided with a flexible connection and
check valve for its inflation.
The fore part of the underframing c has its looped end c', connected to an
inverted U-shaped loop g, threaded upon a pin h, whose inner and screwed end h²,
passes through a rubber cushioning block i, and angular nut (incapable of
rotation) located at the back of a bracket k, secured to and depending from the
fore end of the saddle seat, which pin has a square head h at its end for its
rotation.
In carrying out the second part of my invention, I make the rod or wire metallic
underframings, and their springs, and also the metallic supporting springs of saddles
from T. cruciform H, square, triangular, or star sectioned wire or metal, either
straight or plain, or twisted.
By making the framings and springs from metal of the sections described, great
strength combined with lightness is acquired.
Figure 3 represents a length of straight or plain H or headed sectioned wire.
c is the length, c¹ the heads and
the web.
Figure 4 represents a length of straight triangular sectioned wire, with rounded
angles.
c is the length, having three rib members c¹.
Figure 5 represents a straight T sectioned length of wire with the corners
rounded off.
c is the length and c¹ the rib members.
Figure 6 represents a straight or plain cruciform sectioned length of wire, with
rounded angles.
c is the length and e' the globular sectioned ribs.
Figure 7 represents a similar section to Figure 3, but with the heads made
circular.
Figure 8 is another similar plain H section to Figure 3, but with a broader web
and flattened ends or heads.
Figure 9 is a like plain cruciform section as Figure 4, but with the branches
only rounded at the ends.
Figure 10 represents the plain section Figure 3, twisted.
Figure 11 represents the plain section Figure 4 twisted.
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:-
First. In cycle saddles, employing in connection with pneumatic pillars or
framing supports, an elastic relief chamber, substantially as and for the purpose as
described and set forth.
Secondly. Making the underframing and springs of cycle saddles from plain or
straight H, T, cruciform, dumb-bell, triangular or like sectioned wire or rod metal,
substantially as described and set forth.
Thirdly. Making the underframings and springs of cycle saddles from
twisted H, T, cruciform, dumb-bell, triangular or like sectioned wire or rod metal,
substantially as described and set forth. .
