PROVISIONAL SPECIFICATION.
. Improvements in and relating to Velocipedes.
We, CHARLES MONTAGUE LINLEY, of 16 Carmalt Gardens, Putney, in the
County of Surrey, and JOHN BIGGS, of 57 Lynette Avenue, Clapham Common,
Clapham, in the County of Surrey, both Engineers, do hereby declare the nature
of this invention to be as follows:-
Our invention relates to certain improvements in the construction of bearings
for the wheels and axles of velocipedes, and it has for its object lightness, simplicity
of construction, and reduction in the cost of manufacture.
We attain this end in the following manner;-We take a length of tube-
preferably weldless steel tube-and in each end thereof we insert a disc stamped
out of sheet steel, and having a semicircular or approximately semicircular, shaped
groove in it. These two discs are kept the proper distance apart by a distance
piece preferably taking the form of a length of tube placed inside the said tube.
The corresponding parts of the bearing races are formed of discs having similar
shaped grooves and adapted to be fixed to the axle in such a manner that they are
capable of lateral adjustment but having no rotative motion thereon. This may be
effected by forming a flat or its equivalent on the axle and forming the holes in the
discs of a D-shape, and by means of suitable lock nuts threaded on the said
axle.
When this bearing is used for wheels adapted to rotate on stud or fixed axles,
small stamped up flanges may be fixed to the tube to form and complete the hub of
the wheel, and when it is used for the pedal crank axle bracket the tube is provided
with suitable brackets or their equivalents to receive the tubular members of
the frame.

Improvements in and relating to Velocipedes.
We CHARLES MONTAGUE LINLEY of 16 Carmalt Gardens, Putney, in
the County of Surrey, and JOHN BIGGS of 57 Lynette Avenue, Clapham
Common, Clapham, in the County of Surrey, both Engineers, 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:-
Our invention relates to certain improvements in the construction of bearings for
the wheels and axles of velocipedes, and it has for its object, lightness, simplicity of
construction, and reduction in the cost of manufacture.
We attain this end in the following manner:-We take a length of tube-
preferably weldless steel tube-and in each end thereof we insert a disc stamped
out of sheet steel and having a semicircular or approximately semicircular shaped
groove in it. These two discs are kept the proper distance apart by a distance piece
preferably taking the form of a length of tube placed inside the tube. The

page_text: corresponding parts of the bearing races are formed of discs having similar shaped
grooves and adapted to be fixed to the axle in such a manner that they are capable
of lateral adjustment but have no rotative motion thereon. This may be effected
by forming a flat or its equivalent on the axle, and forming the holes in the
discs of a D-shape, and by means of suitable lock nuts threaded on the said
axle.
When this bearing is used for wheels, small stamped up flanges are fixed to
the tube to form the flanges of the hub of the wheel, and when it is used for a
pedal-crank axle bracket the tube is provided with suitable sockets or their
equivalents to receive the tubular members of the frame.

In order that our invention may be fully understood we will more particularly
describe it making reference to the accompanying drawing, in which
Figure 1 is a view in sectional elevation of our improved bearing as adapted for
the pedal-crank axle of velocipedes, and Figure 2 is a view in side elevation
thereof; and Figure 3 is a view in sectional elevation of a modification of our
improved bearing showing its adaption to the hub of a wheel.
Throughout these views similar parts are marked with like letters of reference.
Referring to the drawings, A designates the tube forming the barrel of the
bearing. B, B, designate the discs forming parts of the races for the balls.
C designates the distance piece in the tube A, up to which the discs B, B, are
forced. B¹ B' designate the other discs completing the races for the balls; these
discs B B are made adjustable on the axle D either by being screwed thereon and
fixed by lock nuts b, b, as shown by Figure 1, or they are formed with D-shaped
holes to slide on the axle D which has a flat or its equivalent formed thereon, the
discs B', B', in this case being adjusted by means of nuts b¹, b, and locked by the
lock nuts b, b, as shown by Figure 2. The discs B, B, and B¹, B¹, are shaped to
make suitable races for the balls E, E, either as shown by Figure 1, or as
shown by Figure 3, or they may be made of any other suitable shape for the
purpose.
When the bearing is intended for the pedal-crank axle of a velocipede the
barrel A has formed in it or attached to it the necessary sockets or their
equivalents for the attachment of the members of the frame, one of which is shown
by fine dotted lines in Figure 1, and when the bearing is intended for use in wheels
the barrel A forms the hub, and small flanges a, a, are formed thereon or fixed
thereto as shown by Figure 3, and for driving wheels the barrel A is extended to
receive a ring of teeth forming the driving chain wheel as shown in fine dotted
lines in Figure 3.
We wish it to be particularly understood that we do not limit ourselves to the
precise details of construction hereinbefore described, but that we hold ourselves at
liberty to make such changes and alterations as may fully fall within the spirit and
scope of our invention.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed we declare that what
we claim is :-
1. The improved construction of ball bearings, as hereinbefore described and
illustrated by the accompanying drawing.
2. The improved construction of ball bearings forming a complete pedal-crank
axle bracket, as hereinbefore described and illustrated by Figure 1 of the accom-
panying drawing.
3. The improved construction of ball bearings forming the hub of a wheel,
as hereinbefore described and illustrated by Figure 3 of the accompanying
drawing.
4. In a ball bearing the combination with the axle D, of the tubular barrel A, of
the distance piece C, fitting within the barrel A, of the discs B, B, forced in the
barrel A and bedding up against the ends of the distance piece C, of the discs B¹, B¹,

page_text: adjustably mounted on the axle D and locked thereto by suitable lock nuts, and of
the balls or spheres E, E, etc. all combined arranged and operating as and for the
purpose set forth.
