Improvements relating to Machines and Appliances for Drilling
and for Cycle and like Wheel Building.
We, EDWARD HURST and ARTHUR JOHN EDWARD JONES, trading as the Cycle
Speciality Company, of 58, Lawley Street, in the City of Birmingham, Manu-
acturers, do hereby declare the nature of this invention to be as follows:-
This invention consists of improvements relating to machines and appliances
for drilling and for cycle and like wheel building, such improvements being
especially applicable to machines of the type described in our Specification No.
20148 of 1897 on which Letters Patent have been granted to us.
The object of our present invention is to render the machines and appliances
more completely automatic and effective in action and thus to ensure the more
rapid and accurate drilling of wheel rims and other articles and the fixing of the
whole of the spokes of a cycle or like wheel by an unskilled attendant.
In the construction of our improved machines we arrange the wheel retaining
part at right angles to the spoke fixing spindle as with the machines described
in our aforesaid prior specification. The wheel retaining part consists of a pair
of clamping discs or rings connected by arms with their central bosses which
are mounted upon separate shafts. One of the said shafts is arranged in com-
bination with intermittent rotating mechanism to be hereinafter referred to,
whilst the other has flanges or circular projections formed upon it serving as a
rack to gear with a pinion operated by a hand wheel, by means of which the disc
can be reciprocated as required for the purpose of diminishing or increasing

the space between it and its fellow to suit the lengths of the wheel hubs to be
inserted between them. The outer extremity of the rack shaft

which the two rows of balls revolve; the outer extremity of the cone, which
remains stationary, abuts against a thrust screw carried in a pivotted bracket.
The intermittent rotating gear arranged in combination with the clamping
ring opposite to that mounted on the racked shaft hereinbefore described, com-
prises a pair of division wheels or discs.connected together but having the
circumferential division slots of different pitch to suit differently pitched spokes
of wheels to be built up on the machine. The notches or divisions in the discs
are engaged by a helical cam as described in our former specification, but the
rotation of the cam is effected by means of spur wheels connected by chain or
other gearing with the belt driven main or first motion shaft of the machine from
35 which the necessary power is also transmitted to the spoke tightening spindle
The intermittent rotating gear is put into action by means of a clutch controlled
by a foot lever, but the movement of the clamping discs is confined to the required
limit by the use of a wheel which has teeth formed around a portion only of it
circumference, and which gears with a pinion having the teeth removed from on
40 part which thus serves as a lock for the pinion until a tooth like projectio
formed at one of its sides is engaged by a similar lateral projection from th

page_text: wheel which brings the ordinary teeth of the wheel into gear with the teeth of the
pinion. The gearing can be put into connection with either the one or the other
of the division discs but the two cannot be in gear together.
Between the central boss of the clamping ring on the shaft connected with the
intermittent rotating gear, and the front bearing in which such shaft is supported,
we place loosely on the shaft a thrust collar containing a single row of balls to
receive the end thrust, which, on the opposite shaft, is received by the ball
bearings arranged at the outer end as hereinbefore described.
We mount the two part spoke fixing spindle in a rotatable framing such as
described in our prior specification, but to permit of the spindle being set at its
various positions by a rotation of the hand wheel in the one constant direction,
we employ additional gearing arranged between the hand wheel and the rotatable
frame. Such gearing consists of bevel wheels communicating the motion of the
hand wheel to a crank plate arranged at right angles thereto, the said crank plate
being connected by a connecting rod with a sector having teeth which gear with
a wheel or pinion on the rear end of the spindle carrier or framing. The notches
or divisions on the hand wheel, which are engaged by a spring stop, are so dis-
posed that the movement from the one division to the other will impart the neces-
sary movement to the framing of the spoke fixing spindle to bring the latter into
the required angular position.
When using the machine for drilling purposes we detach the clutch coupling
between the two parts of the spindle and connect the same by means of a rigid
coupling consisting preferably of a screwed sleeve, the adjacent inner ends of
the two part spindle being suitably screwed to enter the coupling. When
drilling rims or other articles in which a pair of holes of different diameters
are required in alignment with each other, or in which the holes are required
to be countersunk, we employ a drill having the form of an ordinary pin drill
but made in two parts, the smaller or pin part consisting of a twist drill fitting
within a central socket or aperture in the larger part in which it is secured by
means of a pointed extremity on the ordinary screw or stud by which the com-
plete drill is secured in the tool holder.
For the purpose of providing a parallel lateral adjustment for the complete
spindle with its rotatable frame, we make the supporting standard adjustable
upon the bed of the machine, the movement being preferably effected auto-
matically by gearing arranged to be operated from the intermittent rotating gear
herein before described.

We, EDWARD HURST and ARTHUR JOHN EDWARD JONES, of 53, Gladstone Road,
Sparkbrook, in the City of Birmingham, formerly trading as the Cycle Speciality
Company, of 58, Lawley Street, in the City of Birmingham, Manufacturers, 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 our present invention is to render the machines and appliances
re completely automatic and effective in action and thus to ensure the more
id and accurate drilling of wheel rims and other articles and the tensioning
the whole of the spokes of a cycle or like wheel by an unskilled attendant.
In the construction of our improved machine we arrange the wheel retaining
rt at right angles to the spoke fixing spindle carrier as with the machines described
our aforesaid prior specification. The wheel retaining part consists of a pair
clamping discs or rings, as A and B, connected by arms with their central
osses which are mounted upon separate shafts A B¹. One of the said shafts as A¹
arranged in combination with intermittent rotating mechanism to be herein-
fter referred to, whilst the other (13) has flanges or circular projections as b
formed upon it serving as a rack to gear with a pinion C operated by a wheel or
handle C, by means of which the disc B can be advanced towards the disc A,
for the purpose of rapidly clamping the wheel in position between the discs, or
withdrawn for the release of the wheel. The outer extremity of the rack shaft B¹
is provided with a detachable socket piece B2 having bearing balls arranged within
it to receive the thrust from the clamping disc B. The extremity B3 of the ball
bearing cone inserted within the socket, abuts against a thrust screw D carried

its pivot support and the thrust screw D is thus out of line with the centre of the
clamping disc B, which is shown drawn back to the full extent permissible.
Both shafts A and B are fitted with adjustable centres, after the manner of
the poppet head of a lathe; the special arrangement of the adjustable parts neces-
5 sary for the spindle B' is illustrated by the sectional view of such spindle shown
at Figure 14.
connected
together but having the circumferential division slots of different pitch to suit
40 differently pitched spokes of wheels to be built up on the machine. Each of the
notched or division wheels is engaged by a helical cam such as described in our
former specification, but the rotation of the two cams H and J of this machine
is effected by means of spur wheels hand j and K, L, M, and N, driven by the
chain 0, from the first motion shaft 0 of the machine from which the necessary
45 power is also transmitted to the spoke tightening spindle P. The intermitten
rotating gear is put into action by means of a clutch Q controlled by a foo
lever Q; the said clutch is shown in section in the detail view Figure 3, and als
at Figure 4, the latter view being an end section on the line y Figure 3. Ea
movement of the intermittently rotating clamping discs A and B is confined
50 the required limit by the use of the wheel M which has teeth formed around
portion only of its circumference as shown in the detail views at Figures 5 and
and which gears with the pinion L. But the said pinion has the teeth remov
from one part of it as 7 and thus when the said part is brought into cont
with or adjacent to the plain portion of the rim of the wheel M, no motion will
55 transmitted from M to L until, on the continued rotation of M, a tooth
projection m formed at one side of it engages a similar lateral projection f

The intermittent rotating gear arranged in combination with the clamping
disc or ring A, comprises a pair of division wheels or dises F and

page_text: of the pinion. The shaft or spindle on which the wheel K is mounted can be so
moved as to put the said wheel into gear with either the wheel hor j and thus
either the one or the other of the division discs F and G can be driven but not
the two together.
Between the central boss of the clamping ring A on the shaft A¹ connected
with the intermittent rotating gear herein before described, and the front bearing
in which such shaft is supported, we place loosely on the shaft a thrust collar R
containing a single row of balls to receive the end thrust, which, on the opposite
shaft, is received by the ball bearings arranged in the socket B2 herein before
referred to. The thrust collar R is shown in section in the detail view at
Figure 7.
We mount the two part spoke fixing spindle or tool operating spindle P in a
rotatable framing such as described in our prior specification, but to permit of the
spindle being set at its various positions by a rotation of the hand wheel S, (of
the rotatable framing carrying the spindle), in the one constant direction, we
employ additional gearing arranged between the hand wheel and the rotatable
frame. Such gearing consists of bevel wheels s s¹ communicating the motion of
the hand wheel S to a crank plate T arranged at right angles thereto, the said
crank plate being connected by a rod T¹ with a sector 1 having teeth which gear
with a wheel or pinion T on the rear end of the spindle carrier or framing. The
notches or divisions on the hand wheel, which are engaged by a suitable spring
stop, are so disposed that the movement from the one division to the other will
impart the necessary movement to the framing of the spoke fixing spindle to
bring the latter into the required angular position.
When using the machine for drilling purposes we detach the clutch coupling Pl
between the two parts of the spindle and connect the said parts by means of a rigid
coupling consisting preferably of a screwed sleeve, the adjacent inner ends of
the two part spindle being suitably screwed to enter the coupling. When
drilling, rims or other articles in which a pair of holes of different diameters
are required in alignment with each other, or in which the holes are required
to be countersunk, we preferably employ a drill having the form of an ordinary
pin drill but made in two parts, the smaller or pin part consisting of a twist drill
fitting within a central socket or aperture in the larger part, in which it is secured
by means of a pointed extremity on the ordinary screw or stud by which the com-
plete drill is secured in the tool holder.
To provide for adjustment of the centre of the tool operating spindle P to suit
wheel rims of varying width, we make the complete head stock movable upon its
bed on the operation of the screw V, or by other means.
In order that a rim which has been drilled in our machine may be subsequently
replaced therein in the exact position at which it was fixed for drilling, we employ
a position peg, such as U, Figure S, attached to the clamping disc A.
Having now particularly described and, ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. In machines and appliances for drilling and for cycle and like wheel
building, the arrangement and combination of parts for automatically effecting
the required rotary movement of the work, substantially as described and as
illustrated.
2.--In machines and appliances for drilling and for cycle and like wheel
