Improvements in Cycle Saddle Securing Bosses.
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 detail improvements in the securing bosses of cycle
saddles, and has for one of its objects, an adjustable tilt and longitudinal adjustment
for saddles having straight framing wires or straight frames, and another of its
objects, a uniformly embracing body clip.
Thus the first part of my invention relates to the securing of the saddle to the
boss and giving tilt also thereto, whilst the second part relates to an all-round clip
body part, for securing the boss to the L-pin or pillar member.
In carrying out one form of my invention in connection with a split band clip
having lug free ends, the outer cheeks or faces of either side of the clip are pierced
with three excentrically disposed holes, and with a middle and preferably square
piercing, through which latter a square or other sectioned cross bolt passes. Each
of the outer washers or plates has upon its inner face, and near the circumference,
a pivot, which takes into one or other of the three holes in the cheek, whilst the
middle part of the washer has a quadrant-shaped slot, of a breadth equal to that of
the pin, and struck from the centre of the pivot.
The inside faces of the washers have keep grooves for a rod or the rods or frame
sides of the saddle to lie within.
Screw nuts take upon the outer ends of the cross pin, by means of which the
saddle frame is secured to the boss, and the boss to the L-pin or pillar member.
By swinging the keep-grooved washers from pivots located above them, the
placing of the pivot of each side in one or other of the holes determines the
position of the boss for taking upon either an Lpin or an upright pillar, and by
simply loosening a screw nut or nuts at an end or the ends of the cross pin, the
hung washers can be moved aside, fore or aft, and the tilt of the saddle adjusted
and its longitudinal position determined without interfering with the position of
the boss, and when adjusted the screwing up of the nuts affixes the parts in their
required positions.
Outer washers are preferably employed, with keep grooves on the outer sides
instead of the inner sides corresponding to the grooves in the inner washers.
Instead of the pivot pin being carried by the washers, they may be carried by the
cheeks of the clip.
In carrying out another form of my improvements, I provide the two opposite
sides of the cheek with quadrant shaped keep grooves, sinkings or lugs located at
distances apart, so as to comprehend quadrant-shaped areas, and I fit within the
said sinkings or areas, adjustable and sliding quadrant-shaped inner washers or
plates, quadrantly slotted in their middles, and through which latter slots, square
cross pins taking through square holes in the cheeks of the clip pass, and upon
their ends outer washers may be strung, with screw nuts coming at the back of
them.
By moving the quadrant-shaped washers or plates to either the right or the left,
tilt adiustment is effected

page_text: Keep grooves for the holding of the wires or sides of the saddle frame are made
within the opposed faces of the component parts between which they pass.
As a further form of my improvements, I mount the inner and quadrant-slotted
washer upon interual angular studs or lugs, standing from the opposite faces or
cheeks of the boss, with their top and bottom sides curved to the figure of the
quadrant slot and upon which the washers slide for adjustment. A square cross
pin passes through square eyes in the cheeks and through the quadrant slots in the
washers, and its ends may receive outside washers, and be screwed to take the
clamping nuts, whilst the opposed faces of the component parts have coincident
keep grooves in which the wires or sides of the frame lie, and are there secured by
the screwing up of the nut or the nuts on the end or ends of the bolt.
As a still further form, the opposite faces of the cheeks are annularly sunken,
and fitted with diametrically or chord divided washer sections, with the opposed
edges chamfered, so as to make channels or keep grooves for the wires or frame
sides to lie within.
The outside washers have ordinary keep grooves, so that when nuts at the ends
of the square bolt passing through square eyes in the cheeks, are screwed up, the
rods are driven between the splits, and force the section washers asunder, so that
their outer edges then bind against the periphery of the sinking, and their inner
faces against the opposed faces of the adjacent components, hence a tilt adjustment
and securing clip. Some of the inner washers may be toothed or serrated.
In carrying out the second part of my improvements, I make the clip band form
alike unto the turn of a helix, and with the free ends, which are terminated by
bolts or pins, crossing each other, and upon the pin or bolt ends a gapped body
part, having cheeks alike as those already described, is fitted and corresponding
quadrant-slotted or other washers are also provided, although the said clip part
may be used indifferently in connection with bosses of any body construction or
fitting.
By screwing up nuts on the pins or bolts, the said pins or bolts are separated or
drawn asunder, and the cross band is circumferentially tightened around the saddle
support, and on the pressure of the nuts being relaxed, the clip, being made of
steel, resumes its normal figure.

Improvements in Cycle Saddle Securing Bosses.
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 :-
--
This invention relates to detail improvements in the securing bosses of cycle
saddles, and pertains, in the one part, to means for imparting tilt to cycle saddles
having straight framing rods, and in a further part, to the clipping part of
attachment bosses.
Figure 1 of the acompanying drawings represents, in vertical section, a cycle
saddle attachment boss provided with self-contained means for imparting tilt to
straight-framed saddles. The said means consists of frame-gripping washers
moving in a quadrant path.
Figure 2 represents a side elevation of the same.
Figure 3 represents a topside plan of Figure 1.

page_text: Figure 4 represents the several detail washer and chip parts employed.
Figure 5 shows the screw-ended cross pin (upon which the loose parts of the boss
are threaded) in elevation.
Figure 6 represents the outside face of one of the inner and tilting washers.
Figure 7 is the inside view of the said washer Figure 6.
Figure 8 is an inner side view of one of the outer washers, and
Figure 9 is a side elevation of the clip body, showing the lugs comprehending
quadrant-shaped areas on the face thereof.
Figure 10 shows the boss in position and in conjunction with a straight-framed
saddle.
The same letters of reference indicate corresponding parts in Figures 1 to 10 of
the drawings.
a is a nearly all-round band clip, divided or split at a², and having thickened lug
ends a³, with square piercings a, within them, wherethrough the square screw
ended pin b, upon the ends of which the pairs of inner and outer washers c and d,
are threaded, passes. The cheeks or outer faces a³, of the said band clip a, have
lug projections a, the inside edges of which comprehend crossing quadrant-shaped
gaps a, a, (see Figure 9) wherein like-shaped lugs c', formed upon the inside faces
of the inner washers c, take respectively for taking upon an L pin or an upright
pillar support. Thus, when the boss takes upon the horizontal member of an L-pin,
the lugs c¹, take into the quadrant-shaped areas a', but when fitted to an upright
pillar support, then the lugs c', lie within the areas a8. The middles of the tilting
washers have quadrant shaped openings c², forming clearances for the ends b² of
the pin b, on the said washers moving in a quadrant path. The said washers c,
have also keep grooves c³, formed in their outer sides .coming coincident with the
opposed keep grooves d², on the inner sides of the outer washers d, which have
plain holes d', passing through their middles. Taking upon the screwed ends 62,
of the pin b, are nuts e, which when screwed home, bring the faces of the com-
ponent parts together, that is, the washers are brought together, with the straight
frame rods ff, of the saddle g, lying between them and within the keep grooves
formed therein, and with the raised quadrant shaped lugs c, lying within the
quadrant areas a' or a³, according to whether the saddle be secured to an upright
or pin, around which the body clip of the boss is simultaneously drawn and
contracted, hence the securing of the frame to the boss and the boss to the saddle
support.
Figure 11 represents an end elevation of the band clip part of the modified form
of saddle attachment boss shown in Figure 12, in elevation, and with the washers
removed from one end of the pin.
Figure 13 is a section of Figure 12 upon the dotted lines -.
Figure 14 represents an inside elevation and an edge view of the tilting washer
and
Figure 15 represents an inside elevation of the outer washer, and also edge and
end views of the same.
In Figures 11 to 15, a is the body part of the clip, a¹ the clip part, split at a²,
whilst a are the faces or cheeks, having formed within them quadrant-shaped and
crossing grooves or channels a', a', a³, as, wherein like-shaped ribs c', of tilt washers c,
having radial holes 2, through their middles, and keep grooves e³ formed along their
outer faces, seat themselves and traverse. d are outside washers, having keep
grooves d², sunken within them and pierced with long clearance slots d', through their
middles and having overhanging lips or stop ears d³, for coupling them with the tilt
washers. b is the cross pin, with screw ends b', upon which the nuts e, take.
To effect tilt adjustment in both the forms of boss herein described, loosen one or
both of the nuts e, when the component parts of the clamping device separate;
then by moving the tilt washers within their quadrant areas
or grooves, the
necessary tilt is given thereto; the re-screwing of the nuts clamps the boss to
the L-pin or pillar and the frame rods of the saddle to the boss in the adjusted
position.

page_text: Figure 16 represents a further form of boss fitted with means for tilting saddles
having straight framings.
Figure 17 is an end elevation of the same with the outer washer and nut
removed.
Figure 18 represents an end elevation of the clip, separately, showing the two
holes in the cheek, in one or other of which the pivot of the tilt washer takes,
according as to whether the boss is fitted to an L pin or to a pillar member.
Figure 19 represents an elevation and an edge view of the tilt washer separately,
and
Figure 20 is an elevation of the clamping washer.
In Figures 16 to 20, a is the band clip, divided at a² and having lug ends a³,
whose cheeks or outer faces are pierced with holes a³, a", wherein pivots c², of tilt
washers c, take and swing on adjustment. These said washers, which may be
serrated upon their inner faces have quadrant slots 2, made through their middles
and keep grooves c', upon their outer sides coming coincident with like keep
grooves d², of outer washers d, having piercings d', through their middles. is the
square or other sectioned and screw-ended pin, passing through holes a', in the
clip a, and having the component washer parts strung upon its ends and drawn
together by screw nuts e.
By the screwing up of these nuts e, after the tilting washers have been swung
either to the right or the left, the whole of the components of the boss are tightly
clamped together, with the clip firmly embracing the L-pin or pillar member and
the washers gripping and holding the frame sides between them.
It will be understood that in all the preceding arrangements, the frame rods form
a lock for preventing the independent rotation of the tilt washers after the screwing
up of the nuts on the ends of the pin.
Figure 21 represents a longitudinal section of a cycle saddle attachment boss
constructed according to another part of my invention.
Figure 22 represents an edge view of the clip.
Figure 23 represents a front elevation and Figure 24 an edge view of the
segmental inner washers.
a is the clip, split at a², and having lug terminations at a³, the outer faces or
checks of which have circular sinkings a, wherein the parts c¹, c², e³, of split
or sectional washers c, having their opposed edges c¹, chamfered or made wedge-
shape so as to to constitute keep-grooves, and having the outer edges of the top
and bottom sections serrated, lie. The frame rods, of the saddle seat are disposed
and lie between the said split parts and the opposed keep grooves d², of the outer
washers d, so that on the screwing up of the nuts e, on the ends b', of the cross pin b,
the washers are made to close upon each other, and the frame rods f, to wedge
themselves between the splits of the washer sections c', c², c³, thereby forcing the
outer sections up against the inside periphery of the recess a, and at the same
time the backs of the said sections are forced against the backs of the sinkings.
The frictional contact thus created rigidly clamps the whole of the component
parts of the boss in their adjusted positions.
Figure 25 represents an attachment boss band clip constructed according to one
of my improvements and consisting of a helically organized all-round band clip,
with the terminal ends crossing each other and formed into drawing up screw bolts,
over which an end serrated body part, having clamping washers at its ends, is
passed whilst outs take upon the said bolt ends for the drawing together of the
whole of the strung parts.
Figure 26 is a topside plan and Figure 27 an underside plan of the said boss.
a is an all-round and helically-formed clip, terminated by crossing bolt or screwed
stem ends a², upon which washers c and d, with keep grooves c', and ', formed upon
their opposed faces for receiving frame rods, take and are drawn together and
against the serrated ends of the interlocated body part a³, by nuts e, by the screwing
up of which the continuous helical band is drawn entirely around the L-pin or
pillar member and at the same time the clamping washers are closed upon the

page_text: frame rods, hence the boss is clamped to its support and the frame rods to
the boss.
I wish it to be understood that I do not limit myself to the particular forms of
clips herein described, as the tilting washers may be employed in conjunction
with various other type of bosses without departing from the nature of my
invention.
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 the attachment bosses of cycle saddles, constraining one of the washers
of each side to slide or move in a quadrant or semi-circular path, whereby tilt
adjustment of the boss with respect to the saddle support can be effected,
substantially as described and set forth.
Secondly. In tilt-adjustment attachment bosses for cycle saddles providing the
inner and tilt washers, which have middle clearances, with quadrant-shaped or
curved lugs, projections, or ribs, which take into and move within like-shaped
areas or channels formed in the outside faces or cheeks of the clip or body of the
boss, substantially as described and set forth in Figures 1 to 15 of the drawings.
Thirdly. In tilt-adjustment and attachment bosses for cycle saddles, mounting
the inner and tilt washers, which have middle clearances, upon pivots or turning
centres, which admit of the same being turned, and tilt given to the saddle seat,
substantially as described and set forth in Figures 16 to 19.
Fourthly. In the attachment bosses of cycle saddles, fitting within recesses
formed in the cheeks of the clips or body parts, split or sectional washers, with
the splits coming at the middles of the keep grooves for the reception of the
frame rod members, substantially as described and set forth in Figures 21 to 24.
Fifthly. In the band clips of attachment bosses for cycle saddles, making the
same in the form of a continuous band, with the ends formed into shanks, which
cross one another and are preferably screwed for receiving drawing-up screw
nuts, substantially as described and set forth in Figures 25 to 27.
