Improvements in Wheels for Perambulators and other Vehicles.
I, ALFRED ROBERTS, of 19 Ellen Street, in the City of Birmingham,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
}
This invention consists of improvements relating to wheels for perambulators and
other vehicles, my object being to provide simple and effective means for the
attachment of the spokes with the hub or boss of the wheel, and for the adjustment
of the bearing balls in the interior of the hub or boss.
In the application of my invention in one convenient manner I form the body of
the hub or boss from a short length of brass or other tubing cut to the desired
length. Within the tubular or hollow body I insert a ball bearing cup making it
to fit tight enough to prevent it from turning or revolving. I close each end of
the tube with a bush of cast iron or other material, and drill a number of holes
around the periphery of both the tube and bushes for the reception of the inner
ends of the wire spokes which I pass through the metal of the tube into the bush
beneath it. The bush at the inner end of the hub has a hole or aperture for the
admission of the axle, whilst the bush at the opposite or outer end is drilled and
tapped to receive the screw stud or adjusting pin hereinafter described.
In a suitable position upon the portion of the axle entering within the hub I cut
or form a cone or groove to provide, in conjunction with the cup, a seating or
bearing for the balls. The extremity of the axle I preferably taper down to a
point to enter within the conical recess or seating formed in the end of a screw
stud or adjusting pin screwed through the bush at the outer end of the hub.
To place the balls in position I remove the screw stud or adjusting pin and drop
the balls into the interior of the hub. I then allow the axle to project within the
hub beyond its normal or working position, until there is sufficient space between
the bottom of the ball groove on the axle and the end of the ball cup, to allow the
balls to drop through on to their seating. The cup and cone or ball groove are
then adjusted to the relative positions required in working by insertion of the stud
which I screw against the extremity of the axle, a slot being made at the outer
end of the stud to receive the point of a screw driver or other suitable tool, and a
lock nut provided for securing the stud in position after adjustment.
I do not limit the application of my invention to any particular type or pattern
of wheel but adapt the same with such modifications as may be required, in the
construction of wheels for various vehicles.
Dated this 26th day of November 1895.

I, ALFRED ROBERTS, of 19 Ellen Street, in the City of Birmingham,.
Manufacturer, 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 :-
This invention consists of improvements relating to wheels for perambulators and
other vehicles, my object being to provide simple and effective means for the
attachment of the spokes with the hub or boss of the wheel, and for the adjustment
of the bearing balls in the interior of the hub or boss.
In the accompanying sheet of explanatory drawings to be hereinafter referred
to :-
•
Figure 1 is a front or end elevation of a wheel hub constructed in accordance
with my invention, and Figure 2 a sectional side elevation of the same.
Figure 3 is a section and Figure 4 a side elevation representing the hub mounted
upon its axle.
The same reference letters in the different views indicate the same parts.
In the application of my invention in one convenient manner I form the body of
the hub or boss from a short length of brass or other tubing such as A cut to the
desired length. Within the tubular or hollow body I insert a ball bearing cup B
making it to fit tight enough to prevent it from turning or revolving.
I close each end of the tube A with a bush of cast iron or other material, and
drill a number of holes around the periphery of both the tube and bushes for the
reception of the inner ends of the wire spokes C which I pass through the metal of
the tube and screw into the bush beneath it. The bush D at the inner end of the
hub has a hole or aperture for the admission of the axle, whilst the bush E at the
opposite or outer end is drilled and tapped to receive the centre screw or adjusting
pin F.
In a suitable position upon the portion of the axle G entering within the hub I
cut or form a cone or groove to provide, in conjunction with the cup B, a seating
or race for the balls as illustrated at Figure 3. The extremity of the axle I taper
down to a point to enter within the conical recess or seating formed in the end of
the centre screw or adjusting pin F screwed through the bush E at the outer
end of the hub.
To place the balls in position I remove the centre screw or adjusting pin F and
drop the balls into the interior of the hub. I then allow the axle to project within
the hub beyond its normal or working position, until there is sufficient space
between the bottom of the ball groove on the axle and the end of the ball cup, to
allow the balls to drop through on to their seating. The cup and cone or ball
(groove are then adjusted to the relative positions required in working by insertion
of the stud F which I screw into or against the extremity of the axle to form a
support or bearing for the same. A slot is made at the outer end of the stud to
receive the point of a screw driver or other suitable tool, and a lock nut H is
provided for securing the stud in position after adjustment.
I do not limit the application of my invention to any particular type or pattern
of wheel but adapt the same with such modifications as may be required, in the
construction of wheels for various vehicles.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is;-
1. The improved method of mounting a perambulator or other vehicle wheel

page_text: upon its axle comprising the combination of a ball bearing with an adjustable
conical or centre bearing substantially as described.
2. The improved hub for perambulator and other vehicle wheels consisting of a
tube fitted with bushes at each end to which the wheel spokes are attached and
having a ball bearing cup fitted within the same to form in conjunction with a cone
or groove on the axle a suitable race for the bearing balls, the bush at the outer
end of the hub being fitted with a screw stud or pin forming a centre bearing for
the extremity of the axle and a means for adjusting the ball bearing, substantially
as described.
