I, WILLIAM DE COURTNEY, of the firm of Huelser & Co. of Temple Chambers,
London, International Patent and Trade Mark Offices, do hereby declare the
nature of this invention, a communication to me from abroad by Julius Preussger,
of Zittau, in Saxony, Empire of Germany, Manufacturer, to be as follows:-
This invention relates to the means of securing the ball bearings or axle bearings
to the fork ends of velocipede wheels, and more particularly to that kind of ball
bearings, where the balls run upon the conical or conoidal extremity or head of a
pin or stud secured to the fork end.
The object of the improvement is, to fix the said pivotal pin or stud to the
fork end without cutting a screw thread into the latter.
Said purpose may be accomplished in various manners, the principal of which
are hereinafter described with reference to the accompanying drawings, Figs. 1°
to 11.
In Fig. 1 the cone or conoidal bearing a has a projection or shoulder, and the
pin or stud of which it forms a part, is screw-threaded at its end, and introduced
into an aperture or open slot of the fork end, the fixing being effected by means of
a screw nut b with corresponding thread.

In Fig. 2 the cone pivot a has no shoulder, but carries a counter sunk nut c.
In Fig. 3, the pivot a has a flange on each side (d and e) and is inserted with its a
smooth central part into a slot of the fork end, in which it is held by a clamping
screw f.

In Fig. 4 the rear side of the pin has a partly counter sunk flange 9 secured to
the fork end by a screw h.
In Fig. 5. the pin of the cone a is inserted into the socket or bore of the fork end,
which has a boss i for increasing the length of said socket and is secured or held by
a clamping screw f.
In Fig. 6 the rear of the cone pivot has a partly counter sunk flange g, as above,
and is secured in the fork by means of a clamping screw-f.
:
In Fig. 7 the cone pivot a is screw-threaded and passes through a nut
which can be shifted up and down in a prismatic guide groove of the fork end.
The cone pin is clamped fast by means of a nut m mounted on the rear end of the
same.

Improvements in Cycles.
I, WILLIAM DE COURTNEY of the firm of Huelser & Co. of Temple Chambers;..
London, International Patent and Trade Mark Offices, do hereby declare the
nature of this invention, a communication to me from abroad by Julius Preussger
of Zittau, in Saxony, Empire of Germany, Manufacturer, and in what manner the
ame is to be performed to be particularly described and ascertained in and by
the following statement :—
This invention relates to the means of securing the ball bearings or axle
bearings to the fork ends of velocipede wheels, and more particularly to that
kind of ball bearings, where the balls run upon the conical or conoidal extremity

accompanying drawings.
The object of the improvement is to fix the said pivotal pin or stud to the fork
-end without cutting a screw thread into the latter.
Said purpose may be accomplished in various manners, the principal of which
are hereinafter described with reference to the accompanying drawings, Figs. 1
to 11.
In Fig. 1 the cone or conoidal bearing a has a projection or shoulder, and the
pin or stud, of which it forms a part, is screw-threaded at its end, and introduced
into an aperture or open slot of the fork end, the fixing being effected by means of
a screw nut b with corresponding thread.
In Fig. 2 the cone pivot a has no shoulder, but carries a counter sunk nut c.
In Fig. 3 the pivot a has a flange on each side (d and e) and is inserted with its
smooth central part into a slot of the fork end, in which it is held by a clamping
BCrew f.
In Fig. 4 the rear side of the pin has a partly counter sunk flange g secured to
the fork end by a screw h.
In Fig. 5 the pin of the cone a is inserted into the socket or bore of the fork end,
which has a boss i for increasing the length of said socket and is secured or held by
a clamping screw ƒ.
In Fig. 6 the rear of the cone pivot has a partly counter sunk flange g as above,
and is secured in the fork by means of a clamping screw f.
In Fig. 7 the cone pivot a is screw-threaded and passes through a nut k
which can be shifted up and down in a prismatic guide groove of the fork end.
The cone pin is clamped fast by means of a nut m mounted on the rear end of the
same.
In Fig. 8, the cone pin a is fixed to a separate carrier t, which in its turn is
secured to the fork end by means of a bolt h or other suitable means.
In the modifications represented by Figs. 9 and 10 the cone pin a is inserted into
a bushing n, which may be secured by means of a screw nut o screwed on to the
end of the said bushing. The cone pin may be easily taken out (and exchanged)
in Fig. 9 from the outside, and in Fig. 10 from the inside.
In Fig. 11 the cone pin a is screwed on to a central spindle or core p by
means of a strengthening sleever, which is held in place by a screw nuts.
In this case, it is essential, that the spindle p passes through the ball bearing or
cone without a screw thread.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is;--
1. A pivotal stud or cone pin adapted to form a conoidal ball bearing and fixed
to the fork end of a velocipede, either directly or by means of a carrier or bushing,
said fork end being free from screw threads, and provided with a smooth bore
or with a slot, substantially as described with reference to the drawings Figs. 1
to 10.
2. A velocipede ball bearing, having a cone pin and an axle which, on the side
where the friction balls are situated, passes through the cone without any screw
thread, substantially as described.
