COMPLETE SPECIFICATION.
Improvements in Cycle Axle Bearings.
I, FREDERICK WILLIAM GOLBY, of 36 Chancery Lane, in the County of Middlesex,
Patent Agent, do hereby declare the nature of this invention and in what manner
the same is to be performed as communicated to me by Eugen van Devoorde, of
14 Brooksstrasse, Bremen, Germany, Engineer, to be particularly described and
ascertained in and by the following statement:-
This invention relates to cycle axle bearings having a double ball race.
The invention is illustrated in the accompanying drawings.
Figs. 1 and 2 are respectively side and end elevations of a cycle driving wheel
axle; and
Figs. 3 and 4 are respectively vertical and horizontal sections taken longitudinally
through the axle, and wheel hub.
In each hub flange b, fixed on the ends of the hub box a, is a ring a which is fitted
thereinto by means of a scrow thread of fine pitch. The ring c forms one half of the
race for the balls k, the other half is formed by the double coned collar g which also
forms half the race for the balls k'. This collar g is on an intermediate box f; at
one end the collar g is fixed, and at the other end it is screwed on the box so as
to be adjustable thereon. The closing rings for the outer races of the balls k¹ are
secured on a disc i which is employed for tightening up.
This disc i is provided with a circular flange internally threaded to which the
rings for the outer races of the balls are screwed. Said disc fits in a box recess
formed in the end cap 7 by bending the edges inwards as shewn in Fig. 3. The end
caps are soldered, rivetted or otherwise firmly secured to the end m of the cycle
frame and are fitted on the axle e by means of long slots as shewn in Figures 2 and 4.
On the end caps 7 are angle plates p having bolt holes through which are passed the
bolts n¹ having eye washer ends n encircling the ends of the axle e and tightened up
by means of nuts thus adjusting the axle and increasing the tension on the driving
chain. The end caps are tightened up by means of nuts on the ends of the axle e.
The space between the disc i and the hub flange b is enclosed by a cover plate 2,
the oil cup in which is closed by means of a cap r. A screws in a screwed
aperture a in the hub a serves to fix the intermediate box f when adjusting the
ball race.
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.
A cycle axle bearing having a double ball race distinguished by the arrangement of
the double ball race between the wheel hub and hub flange on an intermediate box,
and a plate fixed at the point of connection of the cycle frame in such a manner that
the axle, which can be displaced in its bearings to adjust the tension of the driving
chain, does not revolve, the ball race turning on the intermediate box for the purpose
of providing easy running, substantially as bereinbefore described and illustrated in
the accompanying drawings.
