Improvements in Bicycles, Tricycles, and other Velocipedes.
We, WILLIAM ALLDAY, of Springfield, Moseley, in the County of Worcester,
Manufacturer, and ЕDMUND ALLDAY, of Spring Coppice, Knowle, in the County
of Warwick, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
Our invention has reference to those parts of bicycles, tricycles and other
velocipedes which have or may have ball bearings and consists of the improvements
hereinafter described in the cups or casings containing the balls and their races,
the object of our said improvements being to make the said cups practically dust
proof and at the same time oil retaining and thereby to prevent the injury to the
said balls and their races which occurs by the entrance of dust into the said cases
as ordinarily constructed.
We will describe our invention as applied to the hub and spindle of the steering
wheel of a safety bicycle. The hardened steel cup containing the balls is of the
ordinary kind but the hub and cone we employ differ from those ordinarily
employed in the following respects. The interior of the outer end of the hub we
make of somewhat larger diameter than that part of the interior of the hub in
which the cup containing the balls fits; so that when the said cup is fixed in its
place in the hub there is an annular groove at the mouth of the hub; the said
groove consists of the unoccupied space between the cup. and the mouth of the hub.
On the inner face of the flange or disc of the cone we make a projecting ring of a
size and shape suitable to enter and fill the annular groove in the mouth of the hub.
When the parts are put together, that is, when the cone is fixed in position. the
said projecting ring on the inner face of the cone so nearly fills the annular
groove in the hub that the access of air and consequently dust is practically
prevented.
The application of our improvements to the other parts of bicycles, tricycles
and other velocipedes differs in co essential respect from its application to the hub
and spindle of the steering wheel of a safety bicycle as herein before described.

Improvements in Bicycles, Tricycles, and other Velocipedes.
We WILLIAM ALLDAY, of Springfield, Moseley in the County of Worcester,
Manufacturer, and EDMUND ALLDAY, of Spring Coppice, Knowle, in the County
of Warwick Manufacturer, do hereby declare the nature of our 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 reference to those parts of bicycles, tricycles and other
Improvements in Bicycles, Tricycles, and other Velocipedes.
We WILLIAM ALLDAY, of Springfield, Moseley in the County of Worcester,
Manufacturer, and EDMUND ALLDAY, of Spring Coppice, Knowle, in the County
of Warwick Manufacturer, do hereby declare the nature of our 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 reference to those parts of bicycles, tricycles and other

page_text: velocipedes which have, or may have, ball bearings and consists of the improve-
ments hereinafter described in the cups or casings containing the balls and their
races, the object of our said improvements being to make the said cups practically
dust proof and at the same time oil retaining and thereby to prevent the injury to
the said balls and their races which occurs by the entrance of dust into the said
cases as ordinarily constructed.
We will describe our invention as applied to the hub and spindle of the steering
wheel of a safety bicycle.
The hardened steel cups containing the balls are of the ordinary kind but the
hub and cones we employ differ from those ordinarily employed in the following
respects. We make the interior of each end of the hub of somewhat larger
diameter than that part of the interior of the hub in which the cup containing the
balls fits so that when the said cup is fixed in its place in the hub there is an
annular groove at the end or mouth of the hub; the said groove consists of the
unoccupied space between the cup and the end or mouth of the hub. On the
inner face of the flange or disc of the cone we make a projecting ring of a size and
shape suitable to enter and practically fill the annular groove in the mouth of
the hub.
When the parts are put together, that is, when the cone is fixed in position, the
said projecting ring on the inner face of the cone so nearly fills the annular groove
in the hub that the access of air and consequently dust is practically prevented.
Figure 1 of the accompanying drawing represents in longitudinal section the hub
and spindle of the steering wheel of a safety bicycle containing our improvements.
Figure 2 is an end elevation of the said hub with the cone removed and Figures 3
and 4 represent the detached cone in vertical section and front elevation
respectively.
The same letters of reference indicate the same parts in the several figures of
the drawing.
a is the hub and a³, a² are the hardened steel bearing cups fitted in the ordinary
way in the ends of the said hub a. The ends or mouths of the hub a are for a
short distance of somewhat larger internal diameter than the cups a³ so that
when the said cups a' are fitted in the ends of the hub a, annular grooves b, b
are formed between the said cups and the ends of the hub. The cones c, c to be
used with the said hub a have attached to them, preferably by brazing, flanged
rings d, d², the inwardly projecting flanges d² of which are of such a size that when
the cones c, c are adjusted on the spindle e they fill or nearly fill the grooves
around the cups a². In this way the ends of the hubs are closed so effectually as
practically to exclude the entrance of dust into the bearings and at the same time
make the hub oil retaining.
b, b
Although we have represented and for convenience prefer to make the groove
filling ring d, d² on the cone c separate from the cone and attach it thereto by
brazing yet we wish it to be understood that the said ring may be formed in one
piece with the cone.
And although we have described and represented our improvements only in
connection with the hub of the steering wheel of a safety bicycle yet we wish it
to be understood that the said improvements are applicable to the hubs of
velocipedes generally as well as to the bearings of the bottom brackets and
pedals and other bearing parts of velocipedes.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed we declare that we
claim as our invention of "Improvements in bicycles, tricycles and other
velocipedes":
Providing the ends of the hubs and other bearing parts of bicycles, tricycles
and other velocipedes with annular grooves around the bearing cups and forming
on or attaching to the cones to be used with the said hubs and other bearing parts

page_text: inwardly projecting rings which when the cones are adjusted on the spindle fill or
nearly fill the said annular grooves for the purposes and substantially as
hereinbefore described and illustrated in the accompanying drawing.
