Improvements in Drilling and Boring Machines.
We JOSHUA BUCKTON AND COMPANY LIMITED, of Well House Foundry in
the City of Leeds, Tool Makers and JOSEPH HARTLEY WICKSTEED of Well
House Foundry aforesaid, Engineer, do hereby declare the nature of this invention
to be as follows:-
Our invention relates to drilling or boring machinery, wherein an arm, cross.
slide or standard only as the case may be, carries upon itself two or more drill
spindle saddles capable of adjustment thereon; but for convenience of description
we shall hereinafter speak of two only.
The object of our improvement is to be able to drill or bore holes in pairs at the
same time and at any given angle with reference to each other and to the main
arm cross-slide or standard, as well as in different planes. Hitherto there has been
difficulty in drilling holes in pairs in the same line at right angles to the main arm
cross-slide or standard with either spindle indifferently placed beyond or within its
fellow in relation to the face of the main arm.
Our improvements consist partly in the arrangement on the main arm cross-
slide or standard as aforesaid of two separate secondary arms each capable of
independent adjustment thereon in a lengthwise direction, and each carrying upon
itself a drill spindle saddle capable of adjustinent along it in a direction at right
angles to the length of the main arm, the two drill spindle saddles being on the
adjacent sides of their respective arms.
By this arrangement of the drill spindles and by the use of our improved driving
gear hereinafter described the two drill spindles can be brought into line parallel
to the main arm, or into a line at right angles thereto and parallel to the secondary
arm or at any intermediate angle and either spindle indifferently may be the nearer
to or further from the face of the main arm, and each spindle can be made to
travel round the other within an angle of 180 degrees, that is to say within a
semicircle.
In addition the main arm, cross-slide or standard, or the secondary arms or the
drill spindles or all or any of them may be made to swivel or rotate and so to
operate in different planes.
Thus with our improved arrangement any pair of holes in a surface may be
drilled or bored simultaneously whatever their relative positions, provided always
that the pair aforesaid are situated within a figure whose length is not greater than
the maximum range of the secondary arms upon the main arm and whose breadth
is not greater than the maximum range of the drill spindle saddles on the secondary
arms, and provided always that the given pair of lioles are not pitched closer
together than the spindles can approach, whilst by swivelling the main arm or the
secondary arms or the drill spindles, or by traversing the main arm or the secondary
arms or the drill spindle saddles. thereon, or by swinging the main arm when made
radial, into successive positions, or by one or more of these motious, all the holes
in the surface over which the swivelling or traverse or swinging extends can be
drilled in pairs and if need be in different planes subject always to the limitations
hereinbefore mentioned.
Our improvements further consist in an arrangement of the driving gear whereby

page_text: the secondary arms and drill spindles can be made to approach each other, over an
arc of 180 degrees, more closely than was possible under other or previous
arrangements.
The driving shaft extending along the main arm may be driven in any well
known and convenient manner but in machines constructed according to our
improved method we transmit the motion from this shaft to the drill spindles
preferably by means of skew bevel gearing..
In one modification of machines constructed with our improvements the main
driving shaft drives two skew hevel socket pinions which are carried each in its
bearing attached to the base of its respective secundary arm one pinion being right
banded as to the skew or inclination of its teeth and the other left handed, that is
to say the opposite hand to the first one. Each of these pinions aforesaid gears
into and drives a skew bevel wheel attached to a shaft carried in and extending
along its respective secondary arın, behind the drill spin.lle, the skew bevel wheel
of one arm being made right handed and that of the other left handed and the
wheels are placed one in front of and the other at the back of the driving shaft in
the main arm, cross-slide, or standard, so that when the two secondary arms are
closely approached to one another these two skew bevel wheels overlap each other
and enable close proximity to be attained.
In the same manner the shaft extending along each secondary arm drives a skew
bevel socket pinion, that of one arm being right handed and that of the other
left handed, and these pinions in their turn gear into and drive skew bevel wheels
on the drill spindles, made right hauded and left handed respectively and so placed
that one wheel is situate and rotates in a plane above, and the other similarly below
the driving shaft in its secondary arm so that when the two drill spindles and the
two secondary arms are closely approached these skew bevel wheels overlap and
enable the drill spindles to be brought very closely together.
The two spindles may however be driven by spur and bevel gear and worm
gear or a combination thereof it being always so arranged that the spindles can
be brought into the relative positions hereinbefore mentioned.
One main arm, cross-slide, or standard may carry more than one pair of
secondary arms arranged as described and our improvements are applicable to
radial as well as to fixed arms.
"
Our improvements further consist of a power feed gear so arranged as to
stop or start the feed of both drill spindles simultaneously and be operated from
one convenient point common to both spindles, and the hand adjusting gear is
also so connected as to operate both spindles simultaneously from the same point
above mentioned. There is in addition a separate disengaging gear for each spindle
to enable its feed or adjustment to be stopped or started independently.

We JOSHUA BUCKTON AND COMPANY LIMITED of Well House Foundry in
the City of Leeds Tool Makers and JOSEPH HARTLEY WICKSTEED of Well
House Foundry aforesaid Engineer 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 :-
Our invention relates to drilling or boring machinery wherein an arm cross slide

page_text: or standard only, as the case may be, carries upon itself two or more drill spindle
saddles capable of adjustment thereon.
The object of our improvement is to be able to drill or bore holes in pairs at the
same time and at any given angle with reference to each other and to the main arm
cross slide or standard, as well as in different planes. Hitherto there has been
difficulty in drilling holes in pairs in the same line at right angles to the main arm
cross slide or standard with either spindle indifferently placed beyond or within its
fellow in relation to the face of the main arm.
Our improvements consist partly in the arrangement on the main arm, cross
slide, or standard, as aforesaid, of two or more separate secondary arms each
capable of independent adjustment thereon in a lengthwise direction, but for
convenience of description we shall hereafter speak of two only, that is to say of
one pair.
Each secondary arm carries upon itself a drill spindle saddle capable of
adjustment along it in a direction at right angles to the length of the main
arm, the two drill spindle saddles being on the adjacent sides of their respective
arms.
By this arrangement of the drill spindles and by the use of our improved
driving gear hereinafter described the two drill spindles can be brought into line
parallel to the main arm, or into a line at right angles thereto and parallel to the
secondary arms, or at any intermediate angle, and either spindle indifferently may
be the nearer to or further from the face of the main arm, and each spindle can
be made to travel round the other within an angle of 180 degrees that is to say
within a semicircle.
In addition, the main arm, cross slide, or standard, or the secondary arms, or all
or any of them may be made to swivel or rotate, and so to operate in different
planes. Thus with our improved arrangement any pair of holes in a surface may
be drilled or bored simultaneously provided always that the pair aforesaid are
situated within a figure whose length is not greater than the maximum range of
the secondary arms upon the main arm, and whose breadth is not greater than the
maximum range of the drill spindle saddles on the secondary arms; and provided
always that the given pair of holes are not pitched closer together than the spindles
can approach.
Whilst by swivelling the main arm, or the secondary arms, or by traversing the
the main arm or the secondary arms, or the drill spindle saddles thereon, or by
swinging the main arm when inade radial, into successive positions or by one or
more of these motions all the holes in the surface over which the swivelling or
traverse or swinging extends, can be drilled in pairs and if need be in different
planes subject always to the limitations herein before mentioned.
Our improvements further consist in an arrangement of the driving gear whereby
the secondary arms and drill spindles can be made to approach each other over
au are of 180 degrees more closely than was possible under other or previous
arrangements.
The driving shaft extending along the main arm may be driven in any well
known and convenient manner, but in machines constructed according to our
improved method we transmit the motion from this shaft to the drill spindles
preferably by means of skew bevel gearing.
In machines so constructed the main driving shaft drives two skew bevel
socket pinions which are carried each in its bearing attached to the base of its
respective secondary arm, one pinion being right handed as to the skew or
inclination of its teeth, and the other left handed, that, is to say the opposite hand
to the first one. Each of these pinions aforesaid gears into and drives a skew bevel
wheel attached to a shaft carried in and extending along its respective secondary arm,
behind the drill spindle, the skew bevel wheel of one arm being made right handed
and that of the other arm left handed and the wheels are placed one in front of
and the other at the back of the driving shaft in the main arm, cross slide or
standard, so that when the two secondary arms are closely approached to one

page_text: another, these two skew bevel wheels overlap each other and enable close proximity
to be attained.
In the same manner the shaft extending along each secondary arm drives a skew
bevel socket pinion, that of one arm being right handed and that of the other left
handed and these pinions in their turn gear into and drive skew bevel wheels on
the drill spindles made right handed and left handed respectively and so placed
that one wheel is situate and rotates in a plane above and the other similarly
below the driving shaft in its secondary arm, so that when the two drill spindles
and the two secondary arms are closely approached these skew bevel wheels
overlap and enable the drill spindles to be brought very closely together.
The two drill spindles may be however driven by spur and bevel gear, and worm
gear, or a combination thereof, it being always so arranged that the spindles can be
brought into the relative positions hereinbefore mentioned.
One main arm, cross slide or standard may carry more than one pair of secondary
arms arranged as described and our improvements are applicable to radial as well
as to fixed or moveable arms.
Our improvements further consist of a power feed gear so arranged as to stop
or start the feed of both drill spindles simultaneously and be operated from one
convenient point common to both spindles, and the band adjusting gear is also
so connected as to operate both spindles simultaneously from the point above
mentioned.
There is in addition a separate disengaging gear for each spindle to enable its
feed or adjustment to be stopped or started independently.
And in order that our invention may be clearly understood we will proceed to
describe it by reference to the accompanying drawings.
Fig. 1 Sheet 1 is an elevation and Fig. 2 Sheet 2 a plan of a machine
constructed according to our invention and in this case the arm is a radial arm.
Fig. 3 Sheet 3 and Fig. 4 Sheet 4 are elevations at right angles to one another,
and
Fig. 5 Sheet 5 a plan view, showing to an enlarged scale the secondary arms,
the plan view Fig. 5 Sheet 5 being shown partly in section.
The same letters or figures indicate throughout the same parts,
A is the main arm carrying on itself the two secondary arms B, C, which in
their turn carry on their adjacent sides the two drill spindle saddles E, F, with
their spindles G, H. Each of the arms B C, is independently adjustable along the
main arm A and each saddle E F is independently adjustable along its respective
arm B or C. The adjustments being effected by means of rack or screw motion
as may be convenient.
The shaft J extending along the main arm A drives the skew bevel socket
pinions K, L, each carried in its respective bearing at the base of the arms B, C.
The socket pinions K, L, drive in their turn the skew bevel wheels M, N,
which are attached to and drive the shafts O, P, extending along the armis B, C,
and these skew bevel wheels M, N, are situated one at the back and the other at
'the front of the driving shaft J which enables the arms B, C, to be closely
approached to one another without the wheels M, N, fouling one another.
The shafts O, P, drive skew bevel socket pinions Q, R carried in bearings S, T,
in their respective saddles E, F, and the pinions Q, R, in their turn drive the
skew bevel wheels V, W keyed to and driving the sockets of the spindles G, H.
The wheels V W being situated one above its driving shaft O and the other below
its driving shaft P in such a manner as to allow the spindles G H on the
arms B, C to be brought into close proximity.
The arrangement of gearing above described causes both the spindles to rotate
in the same direction.
The downward or feed motion of the two spindles is operated either by the hand
wheel 1, or self actingly by the belt cones 2, 3, and worm and worm wheel 4
actuating the bevel gearing 5 and the feed shaft 6 extending along the main
arm A, this shaft 6 drives by means of bevel wheels 7, 8, the feed shafts 9, 10

page_text: of arms B, C, and through the spur gearing 11, 12, actuates pinions gearing into
racks formed on or attached to the upper part of the spindles G, H.
The feed arrangements as above described operate both spindles simultaneously,
but by means of disengaging clutches 13 Fig. 5 Sheet 5 each spindle can by
withdrawing its clutch be disconnected at will and the spindles fed or adjusted
singly.
We do not however confine ourselves to the particular feeding arrangement
shown.
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 radial drilling or boring machines the use and arrangement on the radial
arm or jib, of one or more pairs of secondary arms, each arm of each pair being
made to carry on the side adjacent to its fellow a drill spindle saddle carrying a
drill spindle for the purpose and in manner hereinbefore described.
(2.) In radial drilling or boring machines and in combination with one or more
pairs of secondary arms mounted upon the radial arm or jib each arm of each pair
of secondary arms being made to carry on the side adjacent to its fellow a drill
spindle saddle with its drill spindle the use and arrangement of skew bevel gears
for the purpose herein before mentioned and as hereinbefore and in the drawings
described.
(3.) In drilling or boring machines and in combination with two or more
secondary arms mounted upon the main arm, cross slide or standard or on the
radial arm as the case may be for the purpose of each carrying a drill spindle
saddle with a drill spindle the use of skew bevel gears so arranged that any one
arm shall with respect to its neighbour be as one of a pair of arms for the purpose
of drilling two or more holes at the same time.
(4.) In drilling or boring machines and in combination with one or more pairs of
secondary arms mounted upon the main arm cross slide or standard each arm of
each pair of secondary arms being made to carry on the side adjacent to its fellow
a drill spindle saddle with its drill spindle the use and arrangement of skew bevel
gears for the purpose hereinbefore mentioned and as hereinbefore and in the
drawing with reference to a radial drilling or boring machine described.
(5.) The general arrangement and combination of parts to form a radial drilling
or boring machine as hereinbefore described and as shown in the drawings.
