Improvements in Cycle, Perambulator, and other like Wheels.
FREDERICK WILLIAM MCGRAH, and FRANK EDWARD MCGRAH, Mail Cart
Makers, both of 40, Button Lane, Sheffield, in the County of York, do hereby
declare the nature of this invention to be as follows:-
Our invention has for its object the limitation in the friction and wear and
tear in cycle perambulator and other like wheels and to render the same less
noisy and easier of propulsion in order to obtain these results we employ bear-
ings made from horn ivory bone vulcanite or other similar materials of a size
and shape best adapted to fit on the axle or inside the hub of the said wheels
and so arranged that by mean of screw and lock nuts the said bearings may be
tightened up from time to time to compensate for any wear and so prevent any
side shake and noise consequent thereon.

Improvements in Cycle, Perambulator, and other like Wheels.
FREDERICK WILLIAM MCGRAH. and FRANK EDWARD MCGRAH, Mail Cart
Makers, both of 40, Button Lane, Sheffield, in the County of York, 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 has for its object the limitation in the friction and wear and
tear in cycle perambulator and other like wheels and to render the same less
noisy and easier of propulsion. In order to obtain these results we employ bear-
ings made from horn ivory bone vulcanite or other similar materials of a size
and shape best adapted to fit on the axle or inside the hub of the said wheels
and so arranged that by means of screw and lock nuts the said bearings may be
tightened up from time to time to compensate for any wear and so prevent any
side shake and noise consequent thereon. Having now stated the nature and
object of our invention we hereinto describe the particulars of how the same
is carried out. For this purpose the hole in the hub of the wheel may be made
to receive the axle in the ordinary way the axle however being turned down
smaller and the nonfrictional bearings which may be in the form of rings
fitted or screwed on each end of the bearing part of the axle, the hub of the
077

page_text: a
wheel being hollowed out at each end of a corresponding size and shape so as
to receive and fit the bearings, the outer axle end being provided with
lock nut to tighten up the bearings if needful. In order to further
explain our invention we furnish the enclosed drawing which is a section of hub
hollowed out at each end to receive the bearings. A is the hub, B the non-
frictional bearings, C the axle, and D the locknut to tighten bearings.
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:-
The use of horn, ivory, bone, vulcanite, or other similar noiseless and non-
frictional substances to be applied as bearings for cycle, perambulator, and other
like wheels in the manner herein described.
