Improvements in 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 that class of cycle saddles, described and represented in
several of my former Letters Patent in which rubber blocks, as fulcra or joints,
were interposed between parts, or at the junctions of the metallic framings, and
which constitute or are employed as springs, from or upon which the saddle
seats are resiliently suspended or mounted, and also to the fittings of the said
saddles.
My present invention consists primarily in a novel method of mounting the front
framings, or the back framings, or both the front and back framings of velocipede
saddles, and employing the said rubber blocks or cushioning expedients as the
medium of acquiring the desired resiliency.
In carrying out my invention in connection with the front of a hammock saddle,
I direct and incline upwardly and forwardly from or near the extreme end of the
top side of the fore part of the said framing a pillar or stem, with its extreme upper
end looped, and taking over or upon the hooked end of a tension pin, directed
through a hanging bracket located upon the underside fore part of the seat, and
with a screw pin rear of the said bracket for traversing the tension pin for bringing
taut or tensioning the seat.
The lower end of the said pillar, prop or inclined support has a portion of its
lower part rearwardly directed into an arm or cranked arm, with its end coming
upon the top side of a rubber block located between the underside of the end of the
said cranked arm, and the top side of the framing rods, at a short distance from the
fore end, and with a pin, connector or stay proceeding downwardly from the arm,
through the rubber interposed block, and between the rods of the framing.
The support with its arm, which constitutes a bell cranked lever, and with the
rubber block as the fulcrum, has upon its underside or has directed from its under-
side, a hanging pin or stalk, which passes downwards between the rods of the frame,
and through a rubber block located upon the underside fore part of the framing,
and with a nut or head at the extreme end of the hanging pin coming upon
the underside of the last named rubber block, and which head forms the pull
bearing.
These rubber blocks, which are pull and push blocks, located upon the under and
upper sides of the framing respectively, are disposed out of line with each other, so
that the under block comes forward of the upper block relative to the seating, and
as a weight comes upon the said seating, the bell-cranked lever rocks upon both.
blocks as fulcra, and at the same time compresses them, and turns, by such move-
ment, backwards, in manner as to make the back upper block the primary fulcrum,
whilst the under block is compressed to a corresponding degree by the action
of the bearing end of the stalk through it, and in consequence of the reserved
elasticity acquired by the said blocks consequent upon their compression, the
relieving of the pressure makes the bell cranked lever move forwardly, and stretch
the seat of the saddle out to its normal condition.
The compressing and expanding action of the said blocks at all times act in unison,
hence the imparting to the seat of a saddle, of resiliency with taut action.
The application of my invention to the rears of saddles differs in no essential
respect from its application to the front as described, other than in the dispositions
of the n

page_text: In connection with the said mountings, I may employ loop-coiled, pillar or other
auxiliary springs.
In the fittings part of my invention, to wit, the means of connecting the saddle to
a vertical pillar, or an upright carried by the framing of a machine, I proceed in
nanner following:-
I take a divided clip, or a clip made of two sectional parts, with the wings or
branched extensions upon one side of them pierced horizontally, and through which
a pivot pin passes. The wings at the other side have formed through them, radial
slots, struck from the centre of the before-named pivot pin, upon which the said clip
turns as a centre of motion.
་
Directed horizontally through the radial slots is a cross pin, alike unto the before
named pivot pin, and which said cross and pivot pins are slotted at their ends,
wherein concave faced bearing blocks take, and with the said concaves presented
outwards. Fitted within the ends of the slots are also closure or cottar washers
with concaved or other seats presented innermost.
Taking upon the extreme ends of the said cross and pivot pins come screw
nuts, and between the bearing blocks and the closure or cottar washers come the
framing rods, and by the screwing up of the nuts, the said framing rods, which
lie within the slots cut within the pins, and between the bearing blocks or washers,
are rigidly affixed in position, and at the same time, the sectional clamp is closed
around the upright pillar, and the saddle secured in its desired position, which
is adjustable vertically for tilting, by the cross pin taking through the radial
slots, whilst the whole is adjustable horizontally on the screwing-up parts being
loosened.
Thus, tilting and horizontal adjustments are made by adjusting and sliding the
parts into such positions as may be required upon the frame rods. This done, then
screw up the parts, when the necessary affixing of both saddle to its pillar, and
framing to the connection clip is performed.
When an pin is employed instead of a pillar, in connection with a pierced
framing, or framing composed of single or double sectional sides, I connect the sides
together, in the latter case, by a rigid cross-bridge, directed archwise over the
middle of the frame, and with a screw pin passing vertically through the said bridge,
and taking through a slot, or through holes made downwards through the horizontal
limb of the L pin.
Dated this 8th day of December 1892.

COMPLETE SPECIFICATION.
Improvements in 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 relates to cycle saddles of both the hammock and other types, as
hereinafter described of one part, and to their fittings or connection bosses of the
other part, and which invention is an improvement upon several former Letters
Patent granted to me and bearing date the 2nd day of October 1884 No. 13056;
the 20th day of April 1888 No. 5868; the 13th day of April 1891 No. 6283; the
2nd day of July 1892 No. 12310; and the 28th day of July 1892 No. 13733.
Figure 1 of the accompanying drawings represents, partly in vertical section and
partly in elevation, a hammock cycle saddle provided with improvements. made
according to my invention.
The fore part of the seat of the saddle is shown mounted upon a crank-shaped

page_text: lever, having resilient fulcra joints in the form of rubber blocks or cushioning
bearings, and the supporting framing fitted with a boss attachment for taking upon
a seat pillar.
Figure 2 represents an underside plan of the said saddle, with the attachment
boss or connection means removed.
Figure 3 represents an underside plan of the fore part of the said seat.
Figure 4 is a longitudinal vertical section of the said boss separately, with the
framing rod members broken off.
Figure 5 is a part horizontal section and upon the dotted lines A B Figure 4.
Figure 6 is a transverse vertical section upon the dotted lines C D Figure 5.
Figure 7 shows one of the pins and its adjuncts separately.
Figure 8 is a modification of the pillar connection means as aforesaid.
Figure 9 is a horizontal section of Figure 8 upon the dotted lines E F,
Figure 10 is a vertical section upon the dotted lines G H Figure 9.
whilst
a is the seat of the saddle, supported at front upon and by a lever or a bell
cranked lever b, having an upwardly directed fore part 2 with an upper hooked
end 6, engaging with the looped end c², of a tension screw c, whose inner end passes
through the plain hole d², of a hanging bracket d, rigidly connected to the front
underside of the seat of a saddle, and having at the back of it, a nut e³, which takes
on the back end of the screw c, and which nut, when rotated, causes the said screw
to be drawn in or paid out for tensioning or relaxing the tant of the seat or for the
disconnection of the parts. The lower end of the said lever b, has a rearwardly
directed arm or limb 66, which takes upon the topside of a rubber or other like
cushioning block and joint e, resting upon the topside of front part f³, of the
framing, and with a depending peg 3, passing through the middle of the said
block e, (which is supported by pressure plates e¹) and between the frame members
parts, of the frame members f, which are in double order and located under the
saddle seat from fore to aft.
The under side of the fore part of the lever b, which as aforesaid, is of the bell-
cranked order, has a hanging and pull stem b', with a head or nut 65, at its end, and
between which (or a washer adjacent to it) and the underside and looped part f' of
the framing,, a second rubber or other like interposed cushioning block and
joint g, comes, so that the said bell-cranked lever b, rocks as it were upon the
yielding fulcra and g, as centres; and as the cushion e, is compressed by the
change of position of the said lever, the cushioning block g, is also compressed to a
like extent, and vice versa, by which means resilient mounting and jointing and
automatic seat tension or stretching are obtained.
e,
The rear of the saddle may be also fitted with cushioning blocks and joints,
such as h, supported from pins ', which pass through loops f³, at the rear
connection ends of the framing rods f, whilst loop coiled springs f, may be
located at the rear of the said seat rods, and fabricated from the rod lengths
thereof.
I wish it to be understood that I do not confine myself to the particular form of
mounting the rear end of the saddle, as shown, as other resilient means of support
may be employed.
In the pillar boss Figures 4, 5, 6 and 7, i is a compound clip, consisting of two
sectional parts i, 2, with arms or extensions 3, 3,, ; the former, have
holes through them, wherethrough the body of a slotted-ended pin, passes,
having fitted within the slots ", bearing washers, 7, with bearings or horizontal
channels, made within the opposed faces of them, and between which channelled
bearing surfaces, the rod members f, of the supporting framing come and are there
clamped by nuts, taking upon the outside screwed ends of the said end-slotted
pins. When the compound clip is attached to framings having curved parts for
the purpose of giving tilt to the saddle, no quadrant slot is required.
The other side of the boss is fitted with a like end-slotted pin and cognate
parts as aforesaid, but with the body of the said pin taking through upright or

page_text: radient slots or holes, taking through the arms or extensions i, best seen in
Figures 1 and 4.
The compound clips 1, 2, have semi-circular inside bearing surfaces ¹³, which
embrace the pillar or seat post j, upon the outer side.
The slots, within the arms, of the said compound clip member admit of tilt
being given to the seat of the saddle, so that by screwing up the nuts, at both
sides of the clip, the saddle framing rods are clamped or fixed to the clip, and the
clip, with the seat in its adjusted position, to the piliar.
In the modified forms of clip comprehended under Figures 8, 9 and 10, is a
loop or ring body part, with opposite and screwed trunnion-like ends or pins 2°, and
with opposite and horizontal side gaps or middle clearances ", extending on both
sides from trunnion to trunnion or nearly so, and embraced by sectional or compound
and adjustable clip parts i',, taking upon the body part of the said ring clip 4,
and also having end clearances, wherethrough the trunnion ends and also the
adjacent portions of the loop ", extend, and through the gaps adjacent to the
said trunnious, frame rods f, pass, and lie within opposed bearings 7, 8, formed
within the sectional clip parts i, 2, and threaded washers 7, whilst the whole of
the parts are drawn together by the nuts, taking upon the screwed trunnion-like
ends, and by such drawing up, the sectional parts are closed, the frame rods f, are
clamped between the opposed clamping surfaces, hence the connection of the boss
or clip to the framing, and at the same time the sectional parts i¹, **, are drawn
upon the pillar j.
27
Instead of the cross pins ³, in Figures 4, 5, 6 and 7 being slotted at their ends,
the seat washers or clamping plates may be threaded upon the ends of the screws,
with channels or seatings formed upon their opposed faces for the gripping of the
frame rods f. The opposed seatings of the washers are sunken across the same
or extensions of the same, so as to come in positions suitable for receiving the said
rods f.
Instead of the cross seatings being upon the washers as described, they may be
sunken within bosses or parts of the clips i².
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 :-
First In a cycle saddle, locating between the connection parts of the under
framings, or the ends of the under framings, and the undersides of the saddle seat,
or metallic parts carried by the saddle seat, of pull and push rubber joints, which
both act as fulcra joints and cushioning expedients, substantially as described and
set forth.
Secondly-Supporting or mounting the hind or front parts of the seats of
saddles by, from or upon a lever, or from a lever or bell cranked arm (or levers or
bell cranked arms) whose lower end parts respectively pull and press upon rubber
cushioning block joints or supports, one of which is located upon the front under-
side of the supporting framing of the saddle seat, and the other upon the front of
the top side of the said framing, but rear or inwards of the first named rubber
block joint or resilient support, substantially as described and set forth.
:
Thirdly Supporting the hind or front parts of the seats of saddles by or
from a bell cranked lever b, b', 12, 13, 14, 1, with above and below cushioning
blocks e, g, which form resilient joints and bearings, substantially as described and
set forth.
:-
Fourthly In a saddle frame and seat pillar boss connection, consisting of
sectional and clip parts adapted to embrace the pillar, and to be drawn together by
cross pins, wherein or around which, the seatings of opposed clamping washers or
plates or their equivalents take or come and grip the frame rods, so that on the
screwing up of nuts or their equivalents upon the ends of the pins, the frame rods.
of the saddle are clamped to the connection, and at the same time the connection

page_text: or boss to the seat pillar or other support, substantially as described and set
forth.
Fifthly-In seat pillar bosses or like connections or clamping means, consisting
of an inner ring body part, having trunnion or screw pins at its two opposite sides,
embraced by
and internal clearances made through the ring, and which ring
section pillar clips, having frame rod seatings upon the two opposite sides and with
seating washers or rod clamping plates with opposed rod seatings, coming opposite
them, substantially as described and set forth."
Sixthly: The improvements in the general construction, arrangement and
combination of the parts of seat pillar bosses, substantially as described and set
forth in Figures 4, 5, 6 and 7.
Seventhly-The improvements in the general construction, arrangement and
combination of the parts of seat pillar bosses substantially as described and set forth
in Figures 8, 9 and 10.
