page_text: Improvements in, or additions to, Parts of Cycles.
I, FREDERICK WILLIAM BRIGGS of 6 Matlock Villas, Chesterton Road, Sparkbrook,
near the City of Birmingham, Cycle Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to means for securing or making fast certain adjustable
parts of cycles, such for example as the cap ends of bottom brackets, seat-pillars
taking into the seat lugs, and handle stems or posts, also the adjustable cones of
hubs and the like.
In carrying out my invention in connection with a bottom bracket, I provide
one end of the same with the usual cap which constitutes an inside cup with ball
races for the ball bearings to roll within. This drum cap, which is outside screwed
at its back or outer end, and left plain at its inner part, is adapted to be adjustably
fitted within the screwed mouth or entrance to one side of the bracket, whilst the
other side of the bracket may have a fixed cap end or it may have an adjustable one
and be affixed in the same way as the first named cap, as hereinafter described.
A metallic band clip surrounds the outer periphery of the plain inner end of
the cap, with the outer or free ends of the same directed into one of the sockets
on the barrel or body of the bracket, and with the stem of a headed screw pin
or thumb screw passing through the walls in the socket and through a plain hole
and a screwed hole in the ends of the band clip respectively, so that by screwing
up e pin, the said band clip is drawn tightly around the cap end, which is thus
made fast or locked in its adjusted position.
One end of the band clip may be made fast to the inside of the bracket, and the
other end, which is formed into a thickened stem and wormed may pass through
the walls of the bracket and receive a nut on its outer end, which nut, when
screwed up, draws the band around the end of the cap, which is thus locked or
held in its adjusted position.
The application of my invention to the other adjustable parts of cycles as
enumerated, such as locking the post or stem of the handle bars to the inner tube
of a ball head, and for locking a seat pillar within a seat lug (which is solid or
plain instead of split as usual) differs in no essential respect from its application
to the locking of the caps of bottom brackets in position as described, but it is
understood that in ball head, the usual ring nut is dispensed with and that the
band clip surrounds the split and plain upper end of the inner tube, above the top
of the outer sleeve.

page_text: I, FREDERICK WILLIAM BRIGGS of 6 Matlock Villas, Chesterton Road, Sparkbrook,
near the City of Birmingham, Cycle Engineer, 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 means for securing or making fast certain adjustable
parts of cycles, such, for example as the bearing cups of bottom brackets, and the
adjustable cones of wheel hubs and the like.
Figure 1 of the accompanying drawing represents a safety bicycle bottom
bracket or crank-axle bearing in which the adjustable end bearing cups
are secured in their adjusted position by means arranged according to one form of
my invention.
Figure 2 is a transverse vertical section of the said bracket upon the dotted
line, Figure 1.
Figure 3 is a like section as Figure 1, but which the right hand bearing cup
removed to show more clearly the position and arrangement of the adjustable band
or encircling clip whereby the said cups are secured in place.
Figure 4 is a section of the bracket upon the dotted line a¹, Figure 2.
Figure 5 represents an end elevation, side elevation and a section of one of the
bearing cups separately, and
Figure 6 represents edge and end views of the securing band separately.
The same letters of reference indicate corresponding parts in the several figures
of the drawing.
Thus, the open mouthed and inside screwed ends a', of the bottom bracket a,
are provided with the usual bearing cups b, which constitute inside part ball races,
which together with the corresponding races d', on the cones de, of the spindle d,
constitute the runs for the ball bearings c, to roll within. These cups which are
outside screwed at their back or outer ends b, and are left plain at their inner
part 62 are adapted to be adjustably fitted within the screwed mouths or entrances
of the bracket.
A metallic band clip e, surrounds the outer periphery of the plain inner end 62,
of each of the cups b, and has the ends e', e, of the same directed into one of the
sockets on the barrel or body of the bracket, and with the stem of a screw
pin made fast to the one end e¹, and passing a hole e, in the other end
and also through the walls in the socket at a, and receiving a nut e, on the ex-
treme protruding end e, so that by screwing up the said nut, the said band clip
is contracted and drawn tightly around the plain end of the cup which is thus
nade fast or locked in its adjusted position.
As a modification, one end of the band clip may be made fast to the inside of
the bracket, and the other end, which may be formed into a thickened stem and
wormed, may pass through the walls of the bracket and receive a nut on its outer
end, which nut, when screwed up, draws the band around the end of, the cap,
which is thus locked or held in its adjusted position.
Instead of both the bearing cups being made adjustable and being secured in
their adjusted position by the means herein described, only one of them may be
adjustable whilst the other may be permanently secured in the mouth of the
bracket in any desired way.
Further, instead of drawing up the band by a nut taking upon a protruding
screwed end, the same may be contracted by a taper cotter pin driven through
a plain hole in the said end, or by other suitable means.

page_text: The application of my invention as a means for locking in their adjusted posi-
tions, the adjustable cones of wheel hubs differs in no essential particular from
its application to bottom brackets as herein described.
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:-
In bottom brackets or crank axle bearings and hubs for cycles, locking or
making fast in their adjusted positions, the adjustable bearing cups or cones of
the same by means of encircling metallic bands, located within the interior of the
body of the bracket or hub and drawn up tight or contracted around the said
cups or cones by nuts or equivalents taking upon or engaging with outwardly
protruding screwed or plain ends of the said bands, substantially as described
and set forth.
