PROVISIONAL SI DUIFICATION.
An Improved Drilling Machine.
We JOSEPH BRINDLE of 14 Field Street Failsworth in the County of Lancaster
Mechanic, RICHARD LOVETT READE of New Hall Wythenshaw Road, and JOHN
TAYLOR of 181 Northenden Road, both of Sale in the County of Chester
Merchants, do hereby declare the nature of this invention to be as follows:-
This invention relates to the construction of a drilling machine adapted for the
purpose of drilling a number of holes simultaneously in the hub or in the felloe of
a wheel for the purpose of securing the spokes therein.
The machine is designed principally for drilling the hubs and felloes of the wheels
of perambulators and bicycles or other velocipedes, but it may also be used for
drilling other kinds of wheels, pulleys or drums or for other similar purposes where
it is required to drill a number of holes simultaneously in radial directions round a
circle.
Upon a suitable frame or plate of a circular form we mount in suitable bearings
the required number of drills arranging them in radial positions at equal distances
apart, the bearings being so arranged that the drills can revolve thereon and are
also capable of sliding to and from the centre of the plate.
Upon each drill there is mounted (on a long key or feather) a bevil pinion between
two bearings so that the pinion can drive the drill at the same time that the latter
can slide endwise through the boss of the pinion.
These pinions (and their respective drills) are all caused to revolve simultaneously
by means of a crown wheel in gear with all the pinions and driven by hand or power
in any convenient manner.
If the machine is for drilling the hubs of wheels the points of the drills will of
course be inwards and all converge towards the centre, and at or near the outer ends
of the drills we arrange a circular plate capable of revolving and provided with
inclined curved projections so formed that when this circular plate is revolved by
hand or otherwise the before named projections will force the drills all gradually
inwards.
In some cases when drilling the felloes of wheels pulleys or drums of large
diameter we propose to arrange the drills with their points radiating outwards, in
which case the inclined curved projections will of course have to be so arranged as
to force the drills in the opposite direction or outwards from the centre.

COMPLETE SPECIFICATION.
An Improved Drilling Machine.
We JOSEPH BRINDLE of 14 Field Street Failsworth in the County of Lancaster,
Mechanic, RICHARD LOVETT READE of New Hall Wythenshaw Road and JOHN
TAYLOR of 181 Northenden Road both of Sale in the County of Chester
Merchants, 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 relates to the construction of a drilling machine adapted for the
purpose of drilling a number of holes simultaneously in the hub or in the felloe of
a wheel for the purpose of securing the spokes therein.

page_text: The machine is designed principally for drilling the hubs and felloes of the wheels
of perambulators and bicycles or other velocipedes but it may also be used for
drilling other kinds of wheels pulleys or drums or for other similar purposes where
it is required to drill a number of holes simultaneously in radial directions round a
circle.
The nature of the said invention and the manner in which the same is to be
performed or carried into practical effect will be r. adily understood on reference to
the sheet of drawings hereunto annexed and the flowing explanation thereof.
Fig. 1 on the drawing is a vertical section of th improved drilling machine and
Fig. 2 is a partial plan view showing one of the frills and its adjuncts.
Upon a suitable frame a of a circular form we ount in suitable bearings 6 the
required number of drills c arranging them in rad' il positions at any angle required
and at equal distances apart, the bearings bein so arranged that the drills can
revolve therein and are also capable of sliding to and from the centre of the plate
or frame.
Il caused to revolve simultaneously
pinions d and driven by hand or
nient manner.
Upon each drill c there is mounted (on a lon: key or feather) a bevil pinion d
between two bearings so that the pinion d can crive the drill e at the same time
that the latter can slide endwise through the boss of the pinion d.
These pinions d (and their respective drills) are
by means of a crown wheel e in gear with all th
by power as shown on Fig. 1 or in any other con
If the machine is for drilling the hubs of wheels the points of the drills will of
course be inwards as shown on the drawing and all converge towards the centre,
and at or near the outer ends of the drills we a range a circular plate capable of
revolving and provided with inclined curved projections so formed that when this
circular plate f is revolved by the hand wheel i or otherwise the before named
projections acting in the forks / see Fig. 1 will force the drills c all gradually
inwards simultaneously.
In some cases when drilling the felloes of wheels, pulleys or drums of large
diameter we propose to arrange the drills with. their points radiating outwards, in
which case the inclined curved projections will of course have to be so constructed
or operated as to force the drills in the opposite direction or outwards from the
centre.
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 construction of improved multiple, radial, drilling machines substantially as
and for the purpose herein before particularly described.
