Improved Apparatus to be used in the Construction of Spider

Mechanic, RICHARD LOVETT READE of New Hail, Wythenshaw Road Sale, in the
County of Chester, Merchant and JOHN TAYLOR of 181 Northenden Road Sale in the
County of Chester Merchant do hereby declare the nature of this invention to be as
follows:-
"
.
"
The object of this invention is to construct a kind of "chuck or apparatus for
entering the hubs and rims of "spider" wheels, used for bicycles and other velocipedes
and also for perambulators bath chairs or other carriages so that the hub and rim are
kept perfectly concentric whilst the spokes are being screwed or fixed therein.
The apparatus consists principally of a boss or centre provided with four six or
other convenient number of radial arms the outer ends of which are by preference
connected together and steadied by a circular rim.
Each of these radial arms has a long slot in which is fitted a slide provided with a
short projecting arm having a notch on the outer side.
Through the centre of each radial arm passes a screw which is also tapped through
a hole in the slide so that the latter works thereon like a nut being prevented from
turning round by being fitted in the slot.
The outer end of each screw projects beyond the circular rim so that it can be
turned by a key.
The inner end of each screw revolves in a hole made in the central boss and each
one is fitted with bevil pinion and all these bevil pinions gear into a bevil wheel which
is mounted on a sleeve on the central boss, so that it will be evident that by turning
any one of these screws by means of a handle or key all the remaining screws will be
caused to turn in the same direction, and at the same speed and thus all the slides
..will be either drawn in towards the centre or moved outwards from the same at the
same time.
In the centre of the boss is a movable peg or pin which may be changed to suit the
bore of the 'hub of the wheel
In using the apparatus the hub is placed on the central pin and the rim is placed
round the short notched arms above named. The screws are then turned until all
the notched arms hold the rim firmly when it will be found that the rim is accurately
centered and the spokes can then be screwed or otherwise fixed therein.

Improved Apparatus to be used in the Construction of Spider
Wheels for Bicycles, Perambulators, and other Carriages.
We JOSEPH BRINDLE of 14 Field Street Failsworth in the County of Lancaster
Mechanic RICHARD LOVETT READE of New Hall Wythenshaw Road Sale in the
County of Chester Merchant, and JOHN TAYLOR of 181 Northenden Road Sale in the
County of Chester, Merchant 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 :-
The object of this invention is to construct a kind of "chuck" or apparatus for
centering the hubs and rims of "spider" wheels used for bicycles and other

page_text: velosipedes and also for perambulators, bath chairs or other carriages so that the
hub and rim are kept perfectly concentric whilst the spokes are being screwed or
fixed therein.
Our invention will be readily understood on reference to the annexed sheet of
drawings and the following explanation thereof.
Fig. 1 is a front elevation, and
Fig. 2 a side elevation in section of the apparatus which consists principally of
a boss or centre a provided with four six or other convenient number of radial
arins al the outer ends of which may if preferred be connected together, and
steadied by a circular rim, not shown on the drawings.
Each of these radial arms a¹ has a long slot in which is fitted a slide 6 pro-
vided with a short projecting arm c having a notch on the outer side. A notch
may also be cut on the inner side of the arms c (see Fig. 2) so that the slides
can clip the outside of the rim instead of the inside thereof.
Through the centre of each radial arm a¹ passes a screw d which is also tapped
through a hole in the slide 6 so that the latter works thereon like a nut being
prevented from turning round by being fitted in the slot.
The outer end of each screw d projects beyond the end of the arm a¹ (or the
circular rim) so that it can be turned by a key or other suitable means. The
inner end of each screw d revolves in a hole made in the inner end of the arm a¹
or in part of the central boss a and each one is fitted with bevil pinion e, and
all these bevil pinions e gear into a bevil wheel ƒ which is mounted on a sleeve
on the central boss a so that it will be evident that by turning any one of these
screws d by means of a handle or key all the remaining screws will be caused to
turn in the same direction and at the same speed and thus all the slides 6 will
be either drawn in towards the centre or moved outwards from the same at the
.same time.
In the centre of the boss a is a movable peg or pin g which may
to suit the bore of the hub of the wheel.
be changed
In using the apparatus the hub h is placed on the central pin g and the rim i
is placed round the short notched arms c above named. The screws d are then
turned until all the notched arms c hold the rim i firmly when it will be found
that the rim is accurately centered and the spokes can then be screwed or other-
wise fixed therein.
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 :-
:-
The improved chuck or apparatus for simultaneously centering the hubs and rims
of spider wheels whilst the spokes are being screwed or fixed therein, constructed and
operating substantially as hereinbefore described and illustrated by the drawings
annexed.
