PROVISIONAL SPECIFICATION.
Improvements in, or an Addition to, the Spokes of Wire-spoked
Cycle and other Wheels.
We JOHN BLYTH and WILLIAM ARTHUR LLOYD, trading as W. A. Lloyd
and Company, of Lionel Street, in the City of Birmingham, Cycle Accessories
Manufacturers, do hereby declare the nature of this invention to be as follows:-
This invention has reference to an attachment to be employed in connection
with wire spoked wheels, either laced or otherwise, and has for its object, the
attachment or connection, or detachment or disconnection of the said spokes or
the ends of the spokes, without interfering with the tyre or outer circumference of
the wheel, such for example, as pneumatic, cushion or solid rubber tyres.
By the means employed, the said spokes are also pulled up, or their tension
adjusted as may be desired, as well as for the introduction of new spokes on the
withdrawal of old or broken ones.
In carrying out my invention in connection with a laced spoke, I connect the
outer screwed ends of the same, after the middle parts have been threaded as usual
through the hub, or the flange of the heads of the hub, in each case to a rotating
attachment, with its inner end, which is screwed, taking within the inside screwed
part of a nipple, directed inwardly through the metallic rim of a wheel from the
outside, and with the head at the summit of the said nipple resting upon the outside
periphery of the said rim.
Thus the end of the spoke, which is finely wormed, takes up a screwed hole in
the outer end, or inwardly disposed end of the attachment, which consists of an
inside and an outside screwed plug, stalk, or outside faceted and necked nut, whilst
the inner end of the said attachment, which is more coarsely wormed, takes up a
screwed hole in the shank of the nipple, so that when a spoke is in position, the
rotation of the said attachment or nut, pulls the same up, and firmly secures and
tensions the same in position, without interfering with the tyre, or the covering
thereof, as in the case of a pneumatic one.
The nipple is angular upon its outside, or upon a shoulder of it, and takes
through an angular or suitable shaped hole in the rim, so as to prevent the said
nipple, from rotating, and so also the spokes.
Assuming that a spoke of a wheel, be broken, and requires to be replaced, rotate
in a left hand direction the attachment or pulling up nut, when the broken end of
the spoke gradually becomes disconnected from the nipple. Then replace a fresh
spoke, and screw onto the fine screwed end, the pulling up attachment. Then
screw the coarse screwed end of the said attachment up the like screwed hole in the
nipple, and rotate the attachment in a right hand direction by the angular outside,
when the coarse screwed part traverses up the middle of the nipple, and draws the
spoke up tightly after it. The tightening is performed by virtue of the coarse
threaded part of the attachment travelling at a greater rate up the nipple, than the
fine inside screwed part of it is travelling over the screwed end of the spoke, with
the spoke and nipple having no rotatory motion imparted to them.
The pulling up or tensioning and affixing of the spoke may if necessary be
performed by left hand screwing the ends of the spokes, and the holes in the
attachments, and right hand screwing the inside of the nipple, and end of attachment
taking into it.
In thick spokes, the connection and screwing parts may be of the converse to
that described, so as to make the attachment if necessary screw on the end of the
nipple, and the spoke if butt ended and tapped, screw onto the adjacent end of the
attachment.

page_text: As a further form the attachment may be made to swivel as a nut upon the end
of the nipple.
The application of my invention to various other spokes, differs in no essential
respect to those herein described.

COMPLETE SPECIFICATION.
Improvements in, or an Addition to, the Spokes of Wire-spoked
Cycle and other Wheels.
We, JOHN BLYTH, and WILLIAM ARTHUR LLOYD, trading as W. A. Lloyd
and Company, of Lionel Street, in the City of Birmingham, Cycle Accessories
Manufacturers, 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 the nipples, or the means employed in connection with
.wire-spoked-wheels, for making the connection of, or drawing taut, or tensioning of,
the said spokes, and our said invention has for its object an attachment, or a
screwed attachment for the said nipples, whereby connection or disconnection of the
said spokes, or the ends of them, are made, without at all interfering with the tyre
or the wheel circumference.
Our said invention is applicable to all forms of wheels, and particularly those for
cycles, having pneumatic, cushion or solid rubber tyres, and consists in providing or
fitting each nipple, which comes at the outer end of each spoke, with an attachment
or an independent and separable part, capable of being attached to, and disconnected
from, an end of a spoke, and also adapted to be attached to and detached from, the
nipple, without interfering with the tyre, or the wheel circumference.
By our said attachment, broken spokes can be removed and new ones replaced
with the greatest possible facility.
In carrying out our invention in connection with a laced spoke, each of its outer
screwed ends take up the screwed middle part of an attachment or supplementary
nipple, provided or fitted with an outside screwed stalk or stem, which takes up the
inside screwed middle part of the nipple proper whose head is located within a
sinking, formed within the rim, so that by screwing the attachments full home
within the nipples and then introducing the screwed ends of the spokes into the
entrances to the attachments and then rotating the said nipples and attachments
bodily together the connections of the said spokes to the rim, and the bringing of
the same up taut is thereby accomplished.
Figure 1 of the accompanying drawings represents a portion of a laced wheel
fitted with nipples and attachments or two part nipples, constructed and arranged
according to our invention.
Figure 2 represents upon an enlarged scale, one of the said compound or two
part nipples, but with the attachment part and spoke shown in elevation, and also
the head of the nipple proper.
Figure 3 represents a complete vertical section of the said compound or two part
nipple.
Figure 4 represents the whole of the parts separated.
Figure 5 is a transverse section upon the dotted lines A B Figure 3.
Figure 6 represents the parts separated and with the broken end of a spoke
within the attachment or supplementary part of the nipple.
a is a spoke with the wormed end a³, taking up a like screwed and axial hole 6',
up the middle of an attachment b, consisting of a supplementary nipple, having a

page_text: up the
head or angular part 6', and a screwed stalk or stem 63, which latter takes
screwed hole or middle c, of a nipple c, having a faceted or angular outside part c¹,
and a head c, which latter takes within a seating d¹, of the rim d, of a wheel
circumference e.
To connect and draw up a spoke, first screw home the attachment or supplementary
nipple part into the primary nipple c, and with the shoulder of the said attach-
ment, coming up to the shoulder c of the nipple; this done, pass the tip of the
screwed end a of the spoke a, into the axial hole of the said attachment, and
then rotate the said nipple and attachment bodily together, when the connection of
the spoke to the rim is made and the said spoke pulled up taut or tensioned.
Now assuming that a spoke has been broken and a fresh one desired to be
replaced, first screw out the attachment part with the broken end of the spoke
within it; then remove the said broken end and screw back the attachment full
home into the nipple; then pass the screwed end of the new spoke up the screwed
middle of the attachment, when the same operation for connection and tensioning
is repeated.
As a modification of our invention, the said nipple part c, may be made a fixture,
or non rotatory, in which case, the spoke connections are made and the same pulled
up taut, by the simple screwing in of the attachments, supplementary nipples or
couplings b, after the same have been screwed upon the ends of the spokes.
Or instead of the attachment 6 having a screwed stalk or stem at one end, and
taking up the screwed middle of the nipple proper, it may be enlarged at the said
stalk end, and inside screwed, and take upon an outside screwed end of the said
nipple c.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
First. A two part nipple for the spokes of cycle and other wheels, consisting
of a screwed attachment or coupling of the one part, taking upon the end of a body
or barrel of the other part, substantially as set forth.
Secondly. A two-part nipple for the spokes of cycle and other wheels, consisting
of an outside and inside screwed attachment or coupling of the one part, taking
upon or up the screwed middle of a headed and turning body or barrel of the other
part, substantially as described and set forth.
Thirdly. The improvements in the construction of, or additions to, spoke
nipples for cycle and other wheels, whereby the said spokes are disconnected
connected, and tensioned, or drawn taut by the means, or in the ways, substantially
as described and set forth.
