Wheels.
GEORGE EDWIN TOVEY, The Laurels Moor End Lane, Erdington near
Birmingham, Carpenter, and STEPHEN THOMAS TOVEY, The Laurels Moor End
Lane, Erdington near Birmingham Toolmaker do hereby declare the nature of this
invention to be as follows:-
This invention consists of a hub, the barrel of which has a screw cut on it, its
full length; and two flanges with holes for the reception of the ends of spokes.
One flange is a fixture, the other movable. Also two screwed collars for the
purpose of holding the spokes in their respective positions, and pulling the whole of
them tight at one operation. The loose flange is then fixed in its place by a screw
or pin.

A New or Improved Screwed Hub for Bicycle and Various other
Wheels.
We, GEORGE EDWIN TOVEY, of The Laurels, Moor End Lane, Erdington,
near Birmingham, Carpenter, and STEPHEN THOMAS TOVEY, of The Laurels,
Moor End Lane, Erdington, aforesaid, Toolmaker, 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 the hereindescribed new or improved screwed hub for
bicycle and various other wheels. The construction of our said hub enables all the
spokes to be tightened simultaneously and facilitates the fixing or removal of the
spokes so that a broken spoke can by an inexperienced person be readily removed
and replaced by a new one.
Our invention is illustrated by the accompanying drawing on which Fig. 1 is a
side elevation partly in section of a bicycle or other wheel hub constructed
according to this invention and also shewing parts of the wheel spokes; Fig. 2
shews an end view of the same; Figs. 3 and 4 shew parts of the said hub
separately.
The same letters of reference indicate the same parts in all the figures.
In carrying out this invention the barrel part A of the wheel hub has a screw
thread cut upon it from end to end and is provided with two flanges B and C of
which the flange B is fixed to the barrel A and the other flange Cis movable along
the barrel A. Both of the flanges B and C are made with transverse holes (marked
respectively baud c) for the reception of the ends of the spokes & which as shewn are
bent at about right angles to take into the holes b and c, where the spokes are held
by the two screwed collars E and F which are screw threaded on the barrel A so

page_text: as to move along the same. The collar E has a flange e¹ which bears against
one half of the spokes d and keeps them in place in the holes b in the flange B, and
the other collar F has a flange f which bears against the other half of the spokes d
and keeps them in place in the holes c in the flange C.
In building up the wheel on the hub above described the movable flange C
with its collar F is first moved along the barrel A towards the fixed flange B
and the collars E and F are separated from their respective flanges B and C so
as to permit of the bent ends of the spokes d being introduced into the holes b and c
as shewn in Figs. 1 and 2. The collar E is then screwed up to the flange B so as
to secure the spokes d between the flange e' of the collar E and the flange Bas
shewn in Fig. 1. The collar F is now screwed along the barrel A away from the
collar E thus gripping the spokes d between the flange C and the flange f¹ of the
collar and pulling the whole of the spokes tight at one operation The loose
flange C is then fixed in place by any convenient means as by the split clamping
collar G which is screw threaded on to the boss f' of the collar F and can be
tightened up against the flange C so as to lock the same, and then this collar G is
fixed by tightening up the binding screw g¹ of the collar G. The boss f of the
collar is by preference split at f³ as shewn so that the tightening up of the
collar G on the boss f of the collar F as aforesaid will also tighten and fix
the collar F on the hub barrel A. The collars F and C may be further secured
to their respective flanges by small screws passing therethrough in the holes & see
Figs. 3 and 4.
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 :-
In a hub for bicycle and other wheels the combination of a hub barrel screw
threaded on the outside, a flange fixed thereto and made with holes with which
the spoke ends engage, a collar screwed on said hub and clamping the spokes in the
holes of said flange, a second flange movable along said barrel and made with holes
to receive the spokes and also provided with a collar screwed on said hub to fix the
spokes in said flange, means for locking said movable flange and collar on said
barrel the said parts being so arranged that as the movable flange and collar are
screwed along the hub barrel away from the fixed flange the spokes are tightened
up and as the movable collar and flange are screwed towards the fixed flange and
collar the spokes are slackened, all substantially as hereindescribed and illustrated
by the accompanying drawing.
