PROVISIONAL SPECIFICATION.
Improvements in or connected with the Hub Spindles of Velocipedes
and the like.
We, JAMES FITZGERALD, Artist, of 301, London Road, and HUGH SPROTT
CLEMENT, Manager of the British Patents Company, 121, West Regent Street, both
of Glasgow, Lanarkshire, North Britain, do hereby declare the nature of this inven-
tion to be as follows:-
Hub spindles of both steering and rear wheels of velocipedes presently in use
have been made solid.
According to my present invention I propose to construct these of hollow form,
that is to say, with a tubular passage formed centrally therethrough from end to
end. The two ends respectively would be screw threaded internally. The spindle
due to such arrangement would combine lightness with a minimum degree of
friction.
The extreme ends projecting through and beyond the hub, according to my
invention, would be formed check or stepwise for the reception of the fork ends.
By virtue of screw studs screwed into the tubular ends of the spindle afore-
mentioned, and by suitable screw nuts the fork ends would securely and rigidly be
held in position on the spindle. Or any other suitable means for securing the
said fork ends may be employed.
In lieu of the stepped or checked ends the spindle may conveniently be provided
with two segmental cuts at opposite points for receiving the fork ends which
would be provided with correspondingly shaped holes.

Improvements in or connected with the Hub Spindles of Velocipedes
and the like.
We, JAMES FITZGERALD, Artist, of 301, London Road, and HUGH SPROTT
CLEMENT, Manager of the British Patents Company, 121, West Regent Street, both
of Glasgow, Lanarkshire, North Britain, do hereby declare the nature of this inven-
tion, and in what manner the same is to be performed, to be particularly described
in and by the following statement:
Hub spindles of both steering and rear wheels of velocipedes presently in use

page_text: According to our present invention we propose to construct these of hollow form,
that is to say, with a tubular passage formed centrally therethrough from end to
end. The two ends respectively would be screw threaded internally. The spindle
due to such arrangement would combine lightness with a minimum degree of
friction.
The extreme ends projecting through and beyond the hub, according to our
invention, would be formed check or stepwise for the reception of the fork ends.
By virtue of screw studs screwed into the tubular ends of the spindle afore-
mentioned, and by suitable screw nuts, the fork ends would securely and rigidly be
held in position on the spindle. Or any other suitable means for securing the
said fork ends may be employed.
In lieu of the stepped or checked ends, the spindle may conveniently be provided
with two segmental cuts at opposite points for receiving the fork ends, which
would be provided with correspondingly shaped holes.
In order that our said invention may be properly understood, and readily carried
into effect, we will now proceed to describe the drawings hereunto annexed-
Figure 1 is a longitudinal section of a hub of a rear wheel of a velocipede to
which our improvements are applied.
Figure 2 is a similar view drawn to perspective in order to shew more clearly
certain special features, hereafter more fully referred to, of our said improvements.
Figure 3 is a view corresponding to Figure 1 of the steering or front wheel of the
velocipede made in accordance with, and constituting another feature, of our
invention and,
Figure 4 is a detached view of the end of the hub spindle also hereafter more
fully referred to.
The hub spindle marked is provided with a tubular passage 2, running through
it from end to end. The ends 3, 3, it will be observed, have two segmental cuts 4,
seen more particularly in Figure 2, so as to conveniently receive the rear fork ends,
which as usually constructed, have open elongated slots, not shewn on the
drawings.
A bolt 5 occupies the aforesaid tubular passage 2. The said bolt 5 has a screw
thread cut upon it at either end to receive the screw nuts 6, which clamp the fork
ends 7, 7, securely to the hub spindle, and prevent rotary motion of the said
spindle.
Referring to Figure 3, in lieu of one continuous bolt, as described with reference
to Figure 1, the tubular passage 2 is partially left open the greater part of its
length. The end portions have a female screw thread cut internally around them,
and into these ends short screw studs or bolts 8, 8, are inserted.
The ends 3, 3, of the tubular spindle 1, are stepped, as seen in Figure 4, in
order to receive the perforations or round holes of the fork ends 9, of the steering
wheel, which by virtue of the heads 10, 10 of the bolt or studs 8, 8, are rigidly held
to the spindle 1.
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. In hub spindles of velocipedes and the like; constructing these tubular,
and forming the ends thereof with stepped or segmental recesses, substantially as,
and for the purposes as described and shewn in the accompanying drawings.
Second. The general arrangement and combination of parts operating substan-
tially as, and for the purposes described and shewn in the drawings.
