COMPLETE SPECIFICATION.
Improvements in the Hubs or Naves of Wheels, and in the
Manufacture of the same.
We, HENRY SCORER of Castleford Road, Sparkhill, Birmingham, in the County
of Warwick, Ironmonger and Cycle Accessories Dealer, and RANDOLPH TWIGG of
199 Cooksey Road, Small Heath, Birmingham aforesaid, Cycle Maker, do hereby
declare the nature of our said invention and in what manner the same is to he performed
to be particularly described and ascertained in and by the following statement :-
Our invention has for its object improvements in the hubs or naves of wheels and
in the manufacture of the same which is specially applicable to such light wheels as
those used for oycles where wire tonsion spokes are used. At present they are
generally forged and turned out of a solid block of steel but we make ours by the
combination of several parts in a simple, cheap and expeditious mannor.
In order that our invention may be clearly understood and more easily carried into
practical effect we have appended hereunto a double-sized sheet of drawings upon
which we have given several examples of their construction but it will be understood
that the formation or design may be varied to suit the particular purpose to which
they are applied.
Figure 1.shows such a piece of tubing A as is suitable to form the body or barrel
of one of our hubs.

Figure 2 shows the same piece of tube flanged and cupped at the ends a¹.

Figure 5 is a horizontal section of the hub or nave completed with the spokes
connected thereto.
Figure 6 shows the ball cup B with the external junction piece E made from a
short piece of tube and flanged at el ready to be entered and inclosed in the
ends of A.
Figure 7 shows an alternative mode of forming Eso that the part et embraces the
flange a' of A.
Figure 8 shows the ball cup B and casing E according to Figure 7 brought and
turned over al of A só as to enclose it which illustrates an alternative mode of
procedure in the manufacture of our new hubs.
Figure 9 is a side elevation or plan of the hub made and closed according to the
modification of Figs. 7 & 8.
In making our new hubs or naves we first cut off and flange a piece of tubing A at
each end and raise the flange a' therefrom so as to form a casing or enclosure for the
ball cups B Figure 3 which as seen at Figures 3 and 4 are stampings from steel which
is capable of bardening so as to form enduring bearings. The flange of the cup B
is then entered into the enclosure formed by a¹ of A as seen at Figure 24, when a¹ is
turned down by a suitable press or tools as seen in section at Figure 5. It will be
observed at this Figure 5 that the ends of the spokes S. enter and are secured in
holes which pass through the flange 6 of B and also through the flange a¹ of A and'
the turned part a² of A which gives the spokes a grip or 'hold upon three thicknesses

page_text: of metal A¹, and a' the two thicknesses a¹ and a being tough and unhardened and
the flange hardened with the cup 63 which is formed as usual with the bearing bb,
retaining flange b' and spindle.bole .
The remaining Figures 6 to 9 simply show one of the alternative modifications of
the mode of flanging and construction in which the cup B is enolosed in the short
tube E which is flanged at e¹ and then cupped as seen at Figure 7 so as to enclose
the flange a' of A as seen at Figure 8 in section and at Figure 9 in its finished
condition ready to receive the spokes. By this mode of construction much turning
and boring and workmanship is dispensed with and the advantage is obtained of the
spokes embracing three thickness of metal in the hub flanges as before set forth thus
securing the flanges against being torn out at the spoke holes and the cups B may be
by these means hardened without any interference with the barrel A.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is::-
First. The improvements in the hubs or naves of wheels and in the manufacture of
the same consisting of the centre portion made from tubing and flanged at the end to
enolose the separately stamped cups substantially as herein set forth by Figures 1.to 5
inclusive.
Second. In the manufacture of hubs as set forth in the first claim such like
modifications in the procedure as forming the enclosure flange on the cups to
embrace the centre or barrel portion substantially as herein set forth and illustrated
by Figures 6 to. inclusive.
