PROVISIONAL SPECIFICATION.
An Improved Appliance for Adjusting an 1 Holding Articles whilst
being Drilled or Bored.
I, ARTHUR HATTON, of 176, Charles Henry Street, Birmingham, Warwick-
shire, Engineer and Cycle Manufacturer, do hereby declare the nature of this
invention to be as follows:-
This invention consists of the hereindescribed improved appliance for adjusting
and holding articles whilst being drilled or bored.
At the present time when several articles of the same shape and size, such for
instance as lugs or brackets for velocipedes, are required to be drilled or bored
exactly alike, a jig or holder is used to hold the said lug or other article whilst it
is being drilled or bored this jig or holder being formed with holes to guide the
drill into and corresponding with the holes which are required in the said lug or
other article. As different articles vary in shape and size it is customary to
employ a separate jig or holder with every different size of article. Now
according to my invention I so construct a jig or holding appliance as to be
universal, that is to say, by my invention any one of many different kinds or sizes
of lugs or brackets or other articles can be adjusted and held in the exact
positions required whilst the different holes are being drilled in the article so that
all the holes in the several articles of the same shape and size will correspond, and
a separate jig or holder for each shape and size of article will no longer be
necessary.
My invention is applicable for use with a drilling machine or with a lathe or
other drilling or boring tool. I will describe my invention in connection with
drilling by a drilling machine the holes in a bottom bracket for the crank axle of
a diamond frame safety bicycle such bottom bracket having a through hole for
the crank axle and two other holes in bosses making angles with the hole for the
crank axle.
The body of my said improved tool or appliance has a flat base to stand upon
the table of the drilling machine (or when used with a lathe this base would be
bolted to an 'angle plate) and rising from this base there is a vertical web having
a vertical face to which is bolted a head stock adapted to be moved in a vertical
plane through a certain angle around a horizontal centre pin which secures or
assists in securing the head to the vertical part of the body. The said head has
two outwardly projecting limbs one on each side of the centre pin at a certain
distance apart and through these limbs passes a spindle on which the bracket to be
drilled is threaded. The axis of this spindle is parallel with the vertical face of
the body and by moving the head around its centre as stated above the head with
the said spindle can be set, and by screws or bolts can be fixed, at any desired
angle to the horizontal. The head is made to take spindles of different sizes to
suit the particular size of article which is to be drilled and which is threaded
upon the spindle. At some little distance above the spindle there is a vertical
bush carried in a socket or boss formed with the body the vertical centre of this
bush and of the socket or boss coinciding with the point where the centre line of
the centre pin which connects the head to the body cuts the centre line of the
spindle carried by the head. The said bush forms a guide for the vertical drill of
the drilling machine, and bushes of vations sizes are supplied to suit different

page_text: drills, and the socket or boss in which the bush fits is made large enough in the
hole to take the largest sized bush which is by preference screwed therein the
bottom of the hole in the bush being coned or bellmouthed so as to fit down on to
the boss of the bracket or lug or other article which is to be drilled or hored and
which is threaded on the said spindle underneath. The coned or bellmouthed
shape of the bottom of the hole in the bush thus ensures the boss coming true
with the drill which is to drill the hole in it. The said head with its spindle has
to be set and fixed either horizontal or at the particular angle which the boss,
through which the spindle is threaded, makes with the boss which is to be drilled
and then after one boss has been drilled in the article which is threaded on the
spindle the latter is drawn end wise out of the head and the bracket removed from
the spindle and another bracket threaded thereon which when the coned bush has
been screwed down on to the boss will be in the exact position to be drilled.
In order to maintain the article which is being drilled in its exact position on
the spindle and prevent the bracket or other article turning thereon whilst
another hole is being drilled therein at an angle to the first hole, I provide a plug
or peg which fits in one hole in the bracket or lug when the bracket or lug has
been turned to its exact position for another hole to be drilled and this plug or peg is
carried by a cross bar in front of the head this cross bar being parallel with the
spindle and carried by two quadrant like brackets which are respectively bolted
to the vertical faces of the limbs of the head and arranged to turn round the
spindle as a centre and be fixed by screws or bolts to the said limbs so as to carry
the plug or peg at any desired angle to the drill. The said cross bar which
carries the plug or peg is adapted to be moved end wise in bearings in the ends of
the quadrant like brackets and fixed in any desired position by set screws or by
other means so that the plug or peg can be fixed at any desired position between
the limbs of the head so as to take into the hole which has been drilled in the
bracket or lug which is threaded on the spindle and thus bring the other boss in
position for drilling as aforesaid. The said plug or peg is made so that it can be
readily removed from or replaced in the hole in the cross bar in which it fits.
I provide or I may provide one or more collars on the sliding bar which by set
screws can be fixed in any desired position thereon so as to form stops to limit the
movement of the bar and bring the plug or peg to its desired position in either
direction. The edges of the head and of the vertical web carrying the same are
marked so as to indicate degrees and shew whether the spindle is horizontal or
what angle it makes with the horizontal and in the same way the quadrant like
brackets which carry the cross bar and the plug or peg are similarly marked to
indicate the angle which the plug or peg is making with the drill.
Dated this 6th day of March 1894.

COMPLETE SPECIFICATION.
An Improved Appliance for Adjusting and Holding Articles whilst
being Drilled or Bored.
I, ARTHUR HATTON, of Sherlock Street East, Birmingham, Warwickshire,
late of 176, Charles Henry Street, Birmingham, aforesaid, Engineer and Cycle
Manufacturer, 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 herein-described improved appliance for adjusting
and holding articles whilst being drilled or bored.

page_text: At the present time when several articles of the same shape and size, such for
instance as lugs or brackets for velocipedes, are required to be drilled or bored
exactly alike, a jig or holder is used to hold the said lug or other article whilst it is
being drilled or bored this jig or holder being formed with holes to guide the drill
into and corresponding with the holes which are required in the said lug or other
article. As different articles vary in shape and size it is customary to employ a
separate jig or holder with every different size of article. Now according to my
invention I so construct a jig or holding appliance as to be universal, that is to say,
by my invention any one of many different kinds or sizes of lugs or brackets or
other articles can be adjusted and held in the exact positions required whilst the
different holes are being drilled in the article so that all the holes in the several
articles of the same shape and size will correspond, and a separate jig or holder for
each shape and size of article will no longer be necessary.
My invention is applicable for use with a drilling machine or with a lathe or
other drilling or boring tool. I will describe my invention in connection with
drilling by a drilling machine the holes in a bottom bracket for the crank axle of a
diamond frame safety bicycle such bottom bracket having a through hole for the
crank axle and two other holes in bosses making angles with the hole for the crank
axle, and two smaller bosses for the tubular bottom stays.
On the accompanying drawing Fig. 1 is a general perspective view of my
improved appliance for adjusting and holding articles whilst being drilled or bored;
Fig. 2 is a side elevation; Fig. 3 is a front elevation and Fig. 4 is a plan of the
same; Fig. 5 is a sectional side elevation shewing the appliance in use holding one
of the bottom brackets of a safety bicycle whilst the same is being drilled or bored;
Fig. 6 is a plan of the said appliance shewing how it holds the said bottom bracket
whilst one of the small bosses of the same is being drilled or bored; Fig. 7 is a
sectional front elevation of the said appliance shewing how it holds one of the top
front lugs of a safety bicycle and Figs. 8, 9 and 10 shew details of the said appliance
separately.
The same letters of reference indicate the same or corresponding parts in all the
figures of the drawings.
The body A of my improved tool or appliance has a flat base a¹ to stand upon
the table of the drilling machine (or when used with a lathe this base would be
bolted to an angle plate) and rising from this base a¹ there is a vertical web a²
having a vertical face to which by the bolts 61 62 passing through the arc slots au
in the vertical web a' (and by the centre bolt C hereinafter referred to) is bolted
the head stock B adapted to be moved in a vertical plane through a certain angle
round the horizontal centre pin C which as aforesaid assists in securing the head B
to the vertical part a² of the body. The head B has two outwardly projecting
limbs marked respectively 63 64 one on each side of the centre pin C and at a
certain distance apart and through holes or bearings in these limbs there passes
when the appliance is in use a spindle such as D see Figs. 5, 6, 7 and 9 on which
the bracket or other article to be drilled is threaded. The axis of this spindle D
is parallel with the vertical face a² of the body A and by moving the head B about
its centre pin C as stated above the head B with the spindle D can be set and by
the screws or bolts 162 can be fixed at any desired angle to the horizontal. The
head B is made to take spindles of different sizes to suit the particular sized hole
of the article which is to be drilled and which is threaded upon the spindle. This
is done by making the spindle D fit in the small hole 6 in the arm 63 and by
making a large hole in the arm and supplying loose bushes such as E Fig. 9
each of which will fit in the hole and which are bored out inside to suit the
diameter of the particular spindle to which the bush belongs. At some little
distance above the spindle D there is a vertical bush F carried by a socket or
boss as formed with the body A the vertical centre of this bush F and of the
socket a³ coinciding (see Fig. 4) with the point where the centre line of the centre
pin C cuts the centre line of the spindle D carried by the head B. This bush F

page_text: as in other jigs forms a guide for the vertical drill of the drilling machine and
bushes of various sizes are supplied to suit different drills the socket or boss a³
being made large enough in the hole to take the largest sized bush. These
bushes F are by preference screwed in the socket or boss a³ and the bottom f2 of
the central hole f¹ in the bush F is as usual (see Figs. 5 and 10) made coned or
bellmouthed inside so as (see Fig. 5) to fit down on to the boss g¹ of the bracket or
lug G or other article which is to be drilled or bored and which is threaded on the
spindle D underneath. Thus the coned or bellmouth shape of the bottom of the
hole in the bush F ensures the hole in the boss g¹ being drilled or bored exactly
central with the outside of the boss. The head B with its spindle D has to be set
and fixed either horizontal (see Figs. 1, 2, 3, 4, 5 and 6) or at any particular angle
for instance as shewn by Fig. 7 which the boss of the article to be drilled and
through which the spindle D is threaded makes with the vertical boss which is to
be drilled and then after one boss has been drilled in the article, say for instance
the bottom bracket G, which is threaded on the spindle D the latter is drawn
endwise out of the holes be in the head B and the lug or bracket G is removed
from the spindle and another bracket threaded thereon which when the coned
bush F has been screwed down on to the boss g¹ will as shewn in Fig. 5 be in the
exact position to be drilled.
The edge of the vertical web a² is marked at a with degrees and there is a line 67
on the head B so as to facilitate setting the head B horizontal or at any particular
angle.
In order to maintain the bottom bracket G or other article which is being drilled
in its exact position on the spindle D and prevent the bracket G or other article
turning on the spindle D whilst another hole is being drilled therein at an angle
to the first hole I provide a plug or peg H shewn separately by Fig. 8 which fits
in one hole g² in the bracket or lug G when the bracket or lug has been turned to
its exact position for the other hole to be drilled in the boss g¹ and this plug or
peg H is carried in the boss i¹ of the crossbar 1 in front of the head B, this
crossbar I being parallel with the spindle D and carried by two quadrant like
brackets marked respectively J J2 which are respectively bolted by the
bolts 23 k to the vertical faces of the limbs of the head B and are
arranged to turn on a boss on each of the limbs 636 round the spindle D as
the centre and be fixed by the said screws or bolts to the limbs 636 so as to carry
the plug or peg H at any desired angle to the drill which is operating through the
bush F. The said crossbar I which carries the plug or peg H passes through and
is adapted to be moved end wise in bearings jij in the ends of the quadrant like
brackets J J and fixed in any desired position by the set screws or by other
means so that the plug or peg H can be fixed at any desired position between the
limbs B B of the head B so as to take into the hole which has been drilled in the
boss g in the bracket or lug (as shewn in Fig. 5) which is threaded on the spindle D
and thus bring the other boss g' in position for drilling as aforesaid. The said
plug or peg is made so that it can readily be removed from or replaced in the
hole in the crossbar I in which it fits. I provide, or I may provide, one or more
preferably two collars m² m² on the sliding bar I which by set screws can be fixed
in any desired position thereon so as to come into contact with the face of the
quadrant like brackets J¹ J2 and thus form stops to limit the movement of the
bar I and bring the plug or peg H to its desired position in either direction.
instance this is particularly useful when drilling the small bosses g³ g* of the
bottom bracket G as shewn by Fig. 6 where it will be seen that the collars m² m²
are so fixed on the crossbar I that when the crossbar and plug engaging in the
boss g² of the bottom bracket G are moved along in one direction the collar m
comes in contact with the bearing and thus brings one of the small bosses g³
into its exact position underneath the drill passing through the bush F and then
when this hole has been bored the other collar m' will give the exact position for
moving the crossbar I in the opposite direction to bring the other small boss g¹ in
For

page_text: position under the drill. One of the arms 6 of the head B is at n (see Fig. 4)
marked with degrees and there is an indicating finger marked o on the quadrant
like bracket J so as to indicate the angle which the centre line of the plug or
peg H is making with the vertical centre line of the drill operating through the
bush F.
In order to facilitate holding the bottom bracket G or lug or other article
whilst the first hole is being bored therein true to fit upon the spindle D an
ordinary jig or other means may be used or this may be done by holding the
article between the coned bottom end of the bush F and another bush P which as
shewn by dotted lines in Figs. 3 and 5 I sometimes provide in a boss Q cast on the
base a and bored out true with the centre of the bush F.
The bolts 2 and C which secure the head B to the vertical face a² are made
long enough as shewn to allow of a parallel block being inserted between the back
vertical face of the head B and the vertical face a² so as to throw the centre line
of the spindle D at any required distance in front of the centre of the bush F
so as to bore holes in the bottom bracket lug or other article which are out of
centre.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
1. The improved appliance for adjusting and holding articles whilst being
drilled or bored constructed and arranged substantially as herein before described
and illustrated by the accompanying drawings.
2. In an appliance for adjusting and holding articles whilst being drilled or
bored, the combination of a stand made with a vertical face, a head bolted to said
