Improvements in Metallic-spoked Wheels for Perambulators, Bath-
chairs, Velocipedes, and other Vehicles.
I WILLIAM HENRY DUNKLEY of Jamaica Row Birmingham in the County of
Warwick Perambulator and Carriage Manufacturer, do hereby declare the nature
of this invention to be as follows
My invention has for its object to connect in a simple and efficient manner the
wire or metallic spokes to the hubs or barrels of the wheels of perambulators, bath
chairs velocipedes and other vehicles and at the same time to tighten the said spokes.
This I effect by constructing and combining the parts in the following manner.
I make the back spoke flange of the hub or barrel loose upon the said hub or
barrel so that the said hub or barrel can turn within the loose back spoke flange and
I make the front spoke flange of the hub or barrel screwed in its axis. I also make the
front end of the hub or barrel screwed externally to work in the screwed axis of the front
spoke flange. Each spoke flange is provided with a series of radial tapering holes or
slots the narrow ends of the said holes or slots being outwards and the inner end of
each wire spoke is hooked or turned at right angles and is provided with a head or
button for engaging it with the slot or hole in the spoke flange. The outer headed
ends of the several spokes having been seated in the seats or depressions in the
metallic rim of the wheel in the ordinary way their inner hooked and headed ends are
engaged with the slots or holes in the spoke flanges of the hub or barrel alternating
spokes being engaged with the back and front flanges. By turning the hub or
barrel by the application of a screw driver or tool at its screwed end the said hub or
barrel advances within the front screwed spoke flange which is incapable of rotation
so as to separate the said front spoke flange from the loose back spoke flange. The
alternating wire spokes of the wheel are thereby separated and expanded and
tightened and securely fixed in their flanges. The spokes having been thus expanded
and tightened and fixed a cap is screwed on the projecting end of the screwed hub
or barrel.

Improvements in Metallic-spoked Wheels for Perambulators, Bath-
chairs, Velocipedes, and other Vehicles.
I WILLIAM HENRY DUNKLEY of Jamaica Row, Birmingham in the County of
Warwick, Perambulator and Carriage Manufacturer do hereby declare the nature
of my invention and the manner in which the same is to be performed to be
particularly described and ascertained in and by the following statement :-
My invention has for its object to connect in a simple and efficient manner the
wire or metallic spokes to the hubs or barrels of the wheels of perambulators, bath
chairs, velocipedes and other vehicles, and at the same time to tighten the said
spokes. This I effect by constructing and combining the parts in the following
manner.
I make the back spoke flange of the hub or barrel loose upon the said hub or
barrel so that the said hub or barrel can turn within the loose back spoke flange, and
I make the front spoke flange of the hub or barrel screwed in its axis. I also make
the front end of the hub or barrel screwed externally to work in the screwed axis, of
the front spoke flange. Each spoke flange is provided with a series of radial tapering

holes or slots, the narrow ends of the said holes or slots being outwards and the
inner end of each wire spoke is booked or turned at. right angles and is provided
with a head or button for engaging it with the slot or hole in the spoke flange.
The outer headed ends of the several spokes having been seated in the seats or
depressions in the metallic rim of the wheel in the ordinary way, their inner hooked
and headed ends are engaged with the slots or holes in the spoke flanges of the hub
or barrel, alternating spokes being engaged with the back and front flanges. By
urning the hub or barrel by the application of a screw driver or tool at its screwed
end the said hub or barrel advances within the front screwed spoke flange, which is
incapable of rotation, so as to separate the said front spoke flange from the loose
back spoke flange. The alternating wire spokes of the wheel are thereby separated
and expanded and tightened and securely fixed in their flanges. The spokes having
been thus expanded and tightened and fixed, a cap is screwed on the projecting end
of the screwed hub or barrel.
I will now proceed to describe with reference to the accompanying drawings the
manner in which my invention is to be performed.
Figure 1 represents in front elevation or edge view, a metallic spoked wheel for
a perambulator or other vehicle constructed according to my invention, before the
metallic spokes have been expanded and tension put on them; and Figure 2
represents in side elevation and Figure 3 in front elevation or edge view,
the said wheel after the metallic spokes have been expanded and tightened and a
screw cap applied to the projecting end of the hub or barrel: Figure 4 represents in
en elevation and longitudinal section, the hub or barrel of the wheel drawn to a
larger scale, the front spoke flange being represented in the same position on the
barrel shown in Figure 1, and Figure 5 represents in end elevation and front elevation,
the said hub or barrel drawn to the same scale as Figure 4, with the front spoke flange
in.its fully expanded position or in the position represented in Figure 3; Figure 6
represents a portion of one of the metallic spokes drawn to a larger scale.
The same letters of reference indicate the same parts in the several figures of the
drawings.
a is the hub or barrel of the wheel is the back spoke flange and c is the front
spoke flange of the same; d, d are the wire or metallic spokes attached to the back
flange band.e are the wire. or inetallic spokes attached to the front flange c. The
back spoke flange b is loose upon the barrel a so that the said barrel can turn within
the said loose back flange. This is effected by turning back or expanding the end a²
of the barrel within the ring or tubular part of the said spoke flange b as seen in
the enlarged sectional view Figure 4. The ring or tubular part of the front spoke
flange c is screwed in its interior as shown in the enlarged sectional view Figure 4
and the front half of the barrel a is screwed externally at a³ to work in the screwed
ring or tubular part of the front spoke flange c.
It will be seen by an examination of Figures 4 and 5 that each of the spoke
flanges b and c is provided with a series of equi-distant radial tapering holes or
slots f,f, the narrow ends of the said holes or slots being outwards. The outer ends
of the several spokes d, e are headed in the usual way and are seated in seats or
depressions in the metallic rim g of the wheel and the inner ends of the said spokes
are turned at right angles and are headed.at (see the enlarged view Figure 6) for
engaging in the slots or holes f,f in the spoke flanges.
The screwed end of the barrel a is provided with cross notches a* for receiving
a screw driver or other tool for turning the hub or barrel and the projecting
screwed end of the barrel is covered after the wheel has been completed by the
screw cap i.
In connecting the wire or metallic spokes d, e to the hub or barrel a of the wheel
and tightening the said spokes according to my invention I proceed as follows;-The
front spoke flange c is first turned on the barrel a so as to cause it to approach the
back spoke flange b as represented in Figures 1 and 4. The outer ends of the several
wire or metallic spokes d, e having been seated in the seats or depressions in the
metallic rim 9, the inner hooked and headed ends h of alternating spokes are engaged

page_text: in the slots f, in the back and front spoke flanges b, c as illustrated in Figure 1.
By now turning the barrel a by the application of a screw driver or tool at the nicked
end at of the said barrel, the latter is made to advance within the front screwed spoke
flange c, which is incapable of rotating, the barrel a rotating within the loose back
spoke flange b, which is also incapable of rotating. By the rotation of the barrel a
the front spoke flange c is separated from the loose back spoke flange b and the
alternating wire spokes of the wheel are thereby separated and expanded and tightened
and securely fixed in the flanges b, c of the hub as illustrated in Figure 3. The pro-
jecting screwed end of the hub or barrel a is now covered with the screw cap i and
the wheel completed in the ordinary way.
In order to remove the tension from the spokes when it is required to separate the
parts for packing or transit or to replace a broken or injured spoke it only
necessary to remove the cap i and rotate the barrel a in the direction proper
to cause the spoke flanges to approach one another as represented in Figure 1, when
the broken or injured spoke may be removed and replaced by a new one and tension
again put on the spokes in the manner hereinbefore described..
Having now particularly described and ascertained the nature of my invention
and the manner in which the same is to be performed I wish it to be understood
that I claim as my invention
Constructing the hubs and parts of the hubs and spokes of metallic spoked wheels
for perambulators, bath chairs, velocipedes and other vehicles in the manner herein-
before described and illustrated in the accompanying drawings for the purpose of
expanding and tightening the said metallic spokes and securing them to the hubs;
that is to say, making the back spoke flange of the hub loose upon the end of the
barrel so that the said barrel is capable of rotation within the said loose back spoke
flange and making the front spoke flange screwed in its interior and a portion of the
barrel screwed on its exterior for the screwed front spoke flange to work upon for
the purpose of separating the two spoke flanges and thereby tightening and securing
the metallic spokes to the said flanges substantially as described and illustrated; also
connecting the inner ends of the metallic spokes to spoke flanges of the kind described
and illustrated by making the said inner ends of the spokes hooked and headed
and causing them to engage with radial tapering holes or slots in the said flanges
substantially as described and illustrated.
