PROVISIONAL OF DI
Improvements in certain Machinery or Apparatus for Drilling
Holes in the Boards or Stocks of certain kinds of Brushes
and Brooms.
We, GEORGE SHAW and THOMAS SHAW, both of Warre Street, Ashton-
under-Lyne, in the County of Lancaster, Brush Manufacturers, and JOHN PETER
DITCHFIELD, of the same place, Manager, do hereby declare the nature of this
invention to be as follows:-
Our invention relates to machinery or apparatus of the kind described in the
Specification filed in respect of the application of the above named George Shaw,
Thomas Shaw and John Peter Ditchfield, for Letters Patent, No. 13639, dated
September 21st, 1888, for " Improvements in machinery or apparatus for the
manufacture of certain kinds of brushes and brooms" which machinery or apparatus
is employed for drilling holes in the boards or stocks of hrushes and broonis.
Our invention consists in improvements by which machines of the kind above
mentioned are rendered more efficient in operation.
Our invention consists firstly in means by which it is made possible to bore or
drill in one operation two or more boards or stocks simultaneously by distinct
drills while using one templet and to ensure that all the holes shall be bored or
drilled in the boards or stocks in the required positions and at the required
inclinations.
According to this part of our invention, we provide in constructing a machine,
a templet mounted upon or secured to arms and arranged to be moved backwards
and forwards or to and fro laterally or upwards and downwards or in any two
or more of such modes according to the form of the boards or stocks for the
drilling or boring of holes in which the machine is to be adapted. In conjunction
with the said templet we provide as many holders or sets of parts for holding
boards or stocks to be bored or drilled and so arrange such holders or sets of
parts for holding boards or stocks that when the said templet is moved the said
bolders or sets of parts shall all be moved in a similar manner so that all the
brush boards or stocks held thereby shall be similarly and simultaneously presented
to and withdrawn from the drills by means of which they are to be drilled or
bored. If the boards or stocks to be drilled are not required to be turned into
different positions the holders or sets of parts for holding such boards or stocks
may be mounted or formed upon a bar or frame or bars or frames sliding in guides
or connected by links or link-work to a bar or frame or bars or frames mounted in
a suitable position either in the stationary framework of the machine or in any of
the parts connected to or moved by the templet above mentioned. If the boards
or stocks to be drilled are required to be turned into different positions, the turning
of the holders or parts by which such boards or stocks are held while being drilled
may be accomplished, in cases in which a moderate amount of turning only is
required, by mounting or forming the said holders or sets of parts upon arms or
similar parts connected at each end to an arm or frame or arms or frames and
arranging the said arm or frame or arms or frames so that by one or both ends of
the arms or similar parts upon which the said holders or sets of parts are mounted

page_text: or formed being moved by the movements imparted to the templet employed, the
required, movements of turning and translation may be imparted to the brush
boards or stocks to be drilled. In cases in which a greater degree of turning
movement is required to be given to the boards or stocks to be drilled the holders
or sets of parts for holding the boards or stocks to be drilled may be mounted or
formed upon arms or parts mounted upon suitable pivots in the parts moved with
the templet employed and be arranged to be turned therein by being connected to
arms or other equivalent means by which their movement of translation in relation
to certain parts may be caused to bring about their turning, or the holders or sets
of parts for holding the boards or stocks to be drilled may be mounted or formed
upon arms or parts which may be connected in any suitable manner to toothed
wheels or equivalent devices arranged to be moved in relation to racks or equivalent
means or may be connected in any suitable manner to toothed wheels or equivalent
devices which are capable of being turned by means of the movement of translation
of racks or pinions or equivalent means engaging with them in relation to other
parts. In cases in which the boards or stocks to be bored or drilled require to
have the holes drilled or bored radially therein any suitable dividing apparatus
may be provided and racks or equivalent means acting in conjunction with toothed
wheels or equivalent devices upon the arms or parts upon which the holders or
sets of parts for holding the boards or stocks to be drilled are formed or mounted
may be provided in order that all such holders or sets of parts in the machine may
be turned simultaneously or the said holders or sets of parts may be turned into
the required positions from time to time by hand and secured in the required
positions by any suitable means. A machine constructed according to this part of
our invention is provided with a number of drills corresponding to the number of
boards or stocks to be simultaneously drilled and such drills may receive motion by
means of pulleys and straps or in any other suitable manner. In one arrangement
for imparting motion to the drills to be employed we cause each drill or each group
of any suitable number of drills to be driven by a separate strap and cause all the
straps employed to receive motion from one pulley and to be placed one above
another in their passage around the pulley from which they receive motion.
Our invention consists secondly in improvements in appliances for regulating the
depth of the holes drilled by means of machines of the kind above mentioned.
According to this part of our invention we provide the templet employed in the
machine to which this part of our invention is applied, with a plate of suitable
size connected in any suitable manner to the said templet and made and arranged
so that it can be adjusted and secured by means of a screw or uut or screws or
nuts or other devices in any suitable position in relation to such templet and provide
a stud or stop which may be adjusted and secured by a screw or nut or screws or
nuts or other devices in any suitable position in a stationary part of such machine
so that by the said plate or the said stud or stop or such plate and stud or stop
being adjusted into and secured in a suitable position or positions the extent to
which the templet above mentioned may be moved in one direction may be limited
as may be necessary. In conjunction with the said templet there is employed as
in machines of the kind described in the Specification hereinbefore mentioned a
pin or equivalent device upon or into engagement with which the templet employed
is placed from time to time in order that the drilling or boring of the holes in the
boards or stocks in the positions and at the inclinations desired may be ensured.
In some cases we may provide the templet employed in a machine to which this
part of our invention may be applied with a stud or stop connected thereto in any
suitable manner and made so that it can be adjusted and secured in position in
relation to such templet by means of a screw or nut or screws or nuts or any other
suitable means and provide upon any suitable stationary part of the said machine
a plate of suitable size made and arranged so that it can be adjusted and secured
by means of a screw or nut or screws or nuts or other suitable devices in relation
to such stationary part so that by the said stud or stop or plate or stud or stop and
plate being adjusted into and secured in any suitable position or positions the

page_text: movement of the templet herein before mentioned in one direction may be limited
as may be necessary.
Our invention further consists in a method and means by which machines of the
kind described in the Specification herein before mentioned and machines of the
kind hereinbefore described in reference to a former part of our present invention
may be arranged so that they may work wholly or in part automatically.
According to this part of our invention we provide gearing or mechanism by
which the templet employed in a machine to which this part of our invention is
applied may be caused to advance towards and recede from the pin or other part
into engagement with which it is required to pass from time to time in order to
ensure that the holes drilled in boards or stocks shall be bored or drilled therein in
the required positions and at the required inclinations. This movement of the said
templet towards and away from the said pin or other part may be conveniently
caused by gearing or mechanism so arranged that when the said templet or any
suitable part or parts connected thereto in any suitable manner arrives or arrive or
acts or act against or upon a suitable device or devices provided for the purpose
of effecting the reversal, the action of such gearing or mechanism or the effect of
the action thereof may be reversed. The vertical and lateral movements of the
said templet may also each be produced by means of gearing or mechanism the
action or the effect of the action of which is reversed whenever the said templet or
a part or parts connected thereto in any suitable manner arrives or arrive or acts
or act against or upon a suitable device or devices provided for the purpose of
effecting the reversal of such vertical or lateral movement. The gearing or
mechanism by which the vertical movements of the templet are caused, the gearing
or mechanism by which the lateral movements of the said templet are caused and
the gearing or mechanism by which the backward and forward movements of such
templet are caused may be combined to any suitable extent or two or more separate
sets of gearing or mechanism may be provided for effecting the said several
movements and each or any of such sets of gearing or mechanism may be caused
to control or regulate the action of one or more or all of the other sets of gearing
or mechanism or if the effect of the operation of the gearing or mechanism tending
to cause any particular movement of the templet hereinbefore mentioned be
communicated to such templet by means of springs or other suitable devices by
means of which each movement of the said templet is rendered more or less
independent of the others each of such movements may be imparted to the said
templet as opportunity of motion in any particular direction is afforded to such
templet. The extent of each movement of the templet aforesaid in a vertical or
lateral direction may be regulated by means of suitable stops or other devices
such as a rack and pawls or may be caused by means of a screw or rack or other
equivalent means intermittently revolved or moved in any suitable manner.
templet employed in a machine to which this part of our invention is applied may
be so made that it may act as a scroll or cam in order that it may to some extent
control its own movements. Instead of a machine constructed according to our
invention being arranged so that all the above described movements of the templet
employed in it may be caused to take place automatically a part or parts only of
such movements may be caused to take place automatically.
The
The placing of the boards or stocks to be bored or drilled in position in a machine
arranged according to this part of our invention and the removal therefrom of the
boards or stocks which have been bored or drilled may be effected by hand or may
be arranged to be accomplished by wholly or partially automatic devices.
In another method of arranging a machine according to this part of our invention,
we provide mechanism similar to that above described as being employed to effect
the movement or the part of the movement of the templet above mentioned which
it is desired shall be automatically accomplished but we dispense with the templet
and provide instead thereof, any other means by which the action of such mechanism
may be communicated to the boards or stocks to be drilled or bored and provide
racks and pawls or screws and racks or other devices intermittently rotated or

page_text: moved and suitable stops by means of which the various movements imparted to
the boards or stocks to be drilled or bored may be controlled in the manner
required.

Improvements in certain Machinery or Apparatus for Drilling
Holes in the Boards or Stocks of certain kinds of Brushes
and Brooms.
We, GEORGE SHAW and THOMAS SHAW both of Warre Street, Ashton-
under-Lyne, in the County of Lancaster, Brush Manufacturers and JOHN PETER
DITCHFIELD, of the same place, Manager, 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 machinery or apparatus of the kind described in the
Specification filed in respect of the application of the above named George Shaw,
Thomas Shaw, and John Peter Ditchfield, for Letters Patent, No. 13639, dated
September 21st, 1888 for "Improvements in machinery or apparatus for the
manufacture of certain kinds of brushes and brooms which machinery or
apparatus is employed for drilling holes in the boards or stocks of brushes and
brooms.
Our invention consists in improvements by which machines of the kind above
mentioned are rendered more efficient in operation.
Our invention consists firstly in means by which it is made possible to bore or
drill in one operation two or more boards or stocks simultaneously by distinct
drills while using one templet and to ensure that all the holes shall be bored or
drilled in the boards or stocks in the required positions and at the required
inclinations. This part of our invention also consists in means by which in certain
kinds of machines constructed according to our invention some of the necessary
movements of the brush-boards or stocks being operated upon in a machine may be
accomplished by means of gearing arranged in the machine instead of by the simple
application of manual power to the templet employed in such machine.
According to this part of our invention, we provide in constructing a machine, a
templet mounted upon or secured to arms and arranged to be moved backwards
and forwards or to and fro laterally or upwards and downwards or in any two or
more of such modes according to the form of the boards or stocks for the drilling
or boring of holes in which the machine is to be adapted. In conjunction with the
said templet we provide as many holders or sets of parts for holding boards or
stocks to be bored or drilled as it is desired to bore or drill by one operation in
the machine and so arrange such holders or sets of parts for holding boards or
stocks that when the said templet is moved the said holders or sets of parts shall
all be moved in a similar manner so that all the brush-boards or stocks held thereby
shall be similarly and simultaneously presented to and withdrawn from the drills
by means of which they are to be drilled or bored. The turning of the holders or
parts by which the boards or stocks are held while being drilled necessary to enable
the holes to be drilled at the required inclinations may be accomplished, in cases in
which a moderate amount of turning only is required, by mounting or forming the
said holders or sets of parts upon arms or similar parts connected at each end to
an arm or frame or arms or frames and arranging the said arm or frame or arms or
frames so that by one or both ends of the arms or similar parts upon which the

page_text: said holders or sets of parts are mounted or formed being moved by the movements
imparted to the templet employed, the required movements of turning and trans-
lation may be imparted to the brush-boards or stocks to be drilled. In cases in
which a greater degree of turning movement is required to be given to the boards
or stocks to be drilled the holders or sets of parts for holding the boards or stocks
to be drilled may be mounted or formed upon arms or parts mounted upon suitable
pivots in the parts moved with the templet employed and be arranged to be turned
therein by being connected to arms or other equivalent meaus by which their
movement of translation in relation to certain parts may be caused to bring about
their turning. A machine constructed according to this part of our invention is
provided with a number of drills corresponding to the number of boards or stocks
to be simultaneously drilled and such drills may receive motion by means of pulleys
and straps or in any other suitable manner. In one arrangement for imparting
motion to the drills to be employed we cause each drill to be driven by a separate
strap and cause all the straps employed to receive motion from one pulley and to
be placed one above another in their passage around the pulley from which they
receive motion.
One arrangement of machine constructed according to this part of our invention
is illustrated by Figs. 1, 1ª, 2, 3, 4, 5, 6, 7, 8, 9 and 10 of the accompanying
drawings.

In Fig. 6 which is a side elevation in which part is indicated in outline only and
in Fig. 7 which is an end elevation of a portion of the machine, certain parts which
are omitted from Figs. 1, 2, 3, 4, and 5 are shown.
Figs. 6 and 7 are drawn upon a larger scale than Figs. 1, 2, and 3.
Fig. 8 is a side elevation, Fig. 9 a front elevation and Fig. 10 a plan, in part
a section taken on the line X X of Fig. 6.
The same letters of reference are applied to corresponding parts in all the said
figures.
The machine illustrated in Figs. 1, 14, 2, 3, 4, 5, 6, 7, 8, 9 and 10 of the
accompanying drawings is adapted to give a certain amount of turning movement
to the brush-boards or stocks being operated upon so that a moderate amount of
spread will be given to the tufts of bristles subsequently inserted in the holes
drilled or bored in such brush-boards or stocks.
In the machine illustrated by Figs. 1, 1^, 2, 3, 4, 5, 6, 7, 8, 9 and 10 (a) is the
templet which is arranged so as to be capable of being moved upwards and down-
wards and sideways in relation to the machine between arms (6) and arms (¹).
The arms (b) of which there are two one at each side of the machine and the
arms () of which also there are two one at each side of the machine are secured
to projections formed upon a bracket (2) secured to a standard (c) mounted upon
the bed (d) which is supported by the legs (d¹). A stud (63) secured by means of
lock nuts to and in position in a projection formed upon a standard (e) mounted
upon the bed (d) of the machine is screwed into the bar (6) at one side of the
machine and passes through the bar (b) at the same side of the machine which is
secured in position upon such stud (3) by lock nuts so that such bars (b) (b¹) are
secured in position and at a suitable distance apart. Another stud (63) at the other
side of the machine in a similar manner secures the other bars (b) (61) in position
and at a suitable distance apart. At each end of the templet (a) is secured a
bracket (f) which is formed of two parts secured together and is provided with a
slot (1) capable of being turned and slidden in which is a stud (g). The studs (g)

page_text: while being capable of being slidden lengthwise of the slots (1) in which they are
respectively placed are prevented from being displaced therefrom by means of nuts
or collars caused to bear against the brackets (f) and secured in position upon the
studs (g) upon which they are respectively screwed by means of lock nuts. To
each of the studs (g) a rod (h) is connected by means of a pin (g) passing through
jaws formed on the stud (g) in conjunction with which such rod (h) is employed.
Each of the rods (h) is capable of being turned about the pin (g) which passes
through it. Each of the rods (h) passes through an eye formed in a stud (į)
capable of being oscillated in an arm formed upon a plate () capable of being
slidden between plates (k) (k¹) which are secured together by bolts (2) and kept
at a certain distance apart by means of distance pieces (43) and are mounted upon
a pedestal (*) which is formed in one with the lower of the said plates and is
mounted upon the bed (d) of the machine. The rods (4) may be secured in position
in the eyes through which they respectively pass by means of set screws screwed
into the said eyes and caused to bear against the said rods (h). In each of the
rods () is formed an eye (h) and a rod (1) entering at each end into one of the
eyes () is secured in such eyes by means of set screws screwed into the rods (h)
and bearing upon the rod (1). Upon the rod (1) are mounted two bars (m) each of
which is capable of being oscillated upon the rod (1) but is prevented from moving
lengthwise thereof by means of one of the rods (h) and a collar formed upon the
rod (). In each of the bars (m) are mounted six brackets (n). Each of the
brackets (n) is formed with a stud which passes through and is secured by a nut
and capable of being oscillated in a hole formed to receive it in the bar (m) in
which the said bracket (n) is mounted. Each of the brackets (n) mounted in one
of the bars (m) is opposite to a similar bracket (a) mounted in the other of such
bars (m). In each of the brackets (n) one end of each of two rods (n¹) is secured
by means of a nut screwed upon the end of the rod (n¹) to be secured by it and the
other end of each of the two rods (n') secured in each of the brackets (") mounted
in one of the bars (m) is secured in the bracket (n) opposite thereto mounted in
the other bar (m). Upon the two rods (n¹) extending between the two opposite
brackets (n) forming one pair of such brackets (n) are mounted two brackets (o)
each of which is capable of being secured in any desired position upon the said
rods (n) by means of set screws. Each bracket (o) is formed with slides upon
which are mounted clamps or jaws (o¹) which are capable of being moved upon
the said slides by means of right hand and left hand screw-threads formed upon an
axle (o) provided with a handle (03) and capable of being revolved in the said
bracket (o) but prevented from being moved endwise therein. Each of the
brackets (n) is formed with an arm (2) which passes through an eye formed in one
of a number of studs (p) each of which is secured by means of nuts but also
capable of being oscillated in one of the two arms (j') which are formed on the
plate () and are connected by rods (7) each of which is secured at each end to
one of such arms (j). Each arm (n²) is capable of being secured in position in
the eye through which it passes by means of a set screw screwed into the said
eye and caused to bear against the said arm (n²). The above described arrange-
ment of the bars (m), arms (12), studs (p), arms (¹) and rods (h) causes all the
brackets (n) to be moved in a similar manner when the templet (a) is moved
laterally or upwards or downwards. A rod or frame (f) which is secured at its
ends to the brackets (f) and templet (a) is connected to a cord which passes over
a suitable pulley or pulleys supported in any suitable manner and is connected
to a weight by which the weight of the templet (a) and the rods (h) and the parts
supported thereby is counterbalanced.
The plate () is provided with a dovetail projection (2) in engagement with
which is placed a plate (9) provided with a notch of a form corresponding with
that of the dovetail projection (2). The plate (g) is kept in position upon the
projection (2) by means of the plates (k) (k¹) between which the plate () and the
plate (g) may be slidden. The plate (j) is formed with a number of holes (3) in
any one of which a pin (r) may be placed and the plate (7) is also formed with a

page_text: number of holes (gl) in any one of which the pin (r) may be placed. Slots are
formed in the plates (k) (k¹) in order to allow the pin (r) to be placed in the
holes () (9) as may be desirable from time to time and to act as guides in which
such pin (7) may be slidden. In the plate (q) is formed a slot (2) which is
curved for a purpose to be hereinafter explained. Above the plate (k) and below
the plate (k) are plates (s) secured together by means of a block (s) through
which passes one end of a connecting rod (t). In the plates (s) holes (2) are
formed so that a pin (15) may be inserted into any one of the holes (s) in the
upper plate (s) and through the slot (92) in the plate (9) into one of the holes (s³)
in the lower plate (s). The pin (15) in being inserted into the holes (2) in the
plates (s) and passed through the slot (2) will also be passed through the slots in
the plates (k) (¹) which will act as guides for such pin (15). The rod (t) is
connected at one end to an arm (") mounted fast upon an axle (u') capable of being
cscillated in bearings formed in a standard (v) mounted upon the bed (d) of the
nachine. The rod (t) is provided with nuts (¹) (2) by which it is secured in
} osition in the block (s). Upon the axle (u') is also mounted an arm (²) to which
is connected one end of a connecting rod (w) the other end of which embraces a
stud (a) secured in a block capable of being secured in any suitable position
in a groove formed in a disc (y) mounted fast upon a transverse shaft (z) capable
of being revolved in bearings provided in a bracket (2) secured to the bed (d)
of the machine. Fast upon the transverse shaft (=) is mounted a worm wheel (3)
into which gears or engages a worm (4) mounted loose upon but prevented from
being moved lengthwise of a shaft (5) provided with a fast pulley (5*) and
a loose pulley (5) and capable of being revolved in bearings provided in
pedestals (6) supported in the legs (d') of the machine. Upon the worm (4) is
formed one part (7) of a friction clutch (7) the other part (7b) of which is
capable of being slidden lengthwise upon the shaft (5) and of receiving motion
therefrom. The part (7b) of the friction clutch (7) is formed with a groove in
which engage pins projecting from jaws formed on one arm of a lever (8) mounted
upon a stud (9) secured in a bracket (9) secured to one of the legs (d') of the
machine. To the other arm of the lever (8) is connected one end of a rod (10)
the other end of which is connected to an arm (11) mounted fast upon au axle (11*)
capable of being oscillated in a bracket (12) secured to the bed (d) of the machine.
Fast upon the axle (11") is also mounted an arm (11) to which is connected one
end of a rod (13) the other end of which is connected to a treadle (14) capable of
being oscillated upon an axle (14) passing through a bracket (14) secured to the
floor beneath the machine. When the treadle (14) is depressed the part (7b) of
the friction clutch (7) will be placed in engagement with the part (7) of such
friction clutch (7) so that if the shaft (5) be revolving the shaft () will also be
caused to revolve and by means of the stud (a), connecting rod (), arın (u²),
axle (u'), arm (u) and rod (t) cause the plates (s) to be moved backwards and
forwards and by means of the pin (15) cause the plates () () to be moved back-
wards and forwards. A spring (10ª) which is compressed to a suitable extent
between a collar (10) secured upon the rod (10) and a bracket (10°) secured to
the lower side of the bed (d) of the machine and serving as a guide to the rod (10)
serves to raise the treadle (14) when such treadle (14) is released by the attendant
and to disengage the part (7b) of the friction clutch (7) from the part (7") thereof
so as to arrest the backward and forward movements of the plates (s).
A bracket (7) secured to one of the legs (d) of the machine serves to prevent
the part (7) of the clutch (7) from moving along with the part (7") thereof when
the treadle (14) is released and so ensures that the disengagement of the part (7")
of the clutch (7) from the part (7") thereof and the cessation of the revolution of
the shaft (2) shall take place promptly when the treadle (14) is released.
In the standard (c) mounted upon the bed of the machine are mounted mandrels
or spindles (16) provided with pulleys (17) there being as many mandrels or
spindles (16) as there are pairs of brackets (n). Each pair of brackets (n) is so
placed that when the templet (a) is in its central position the centre of the space

page_text: groove
included between the two brackets (n) forming the pair and the rods (n¹) extending
between them shall be in line with the axis of one of the mandrels or spindles (16).
Each of the mandrels or spindles (16) is provided with a suitable drill or other
boring or drilling tool (18) mounted in a suitable chuck or holder preferably
screwed upon screw-threads formed on such mandrel or spindle (16). Fast upon
the shaft (5) is mounted a pulley (19). Belts (20) of which there is one for each
of the pulleys (17) are passed around the pulley (19) so as to impart motion to the
pulleys (17), the belt (20) used in imparting motion to the lowest pulley (17) being
placed in contact with the surface of the pulley (19) and the others passing outside
it around the pulley (19) in an order corresponding to that of the pulleys (17), the
belt (20) imparting motion to the uppermost pulley (17) being outermost in passing
around the pulley (19). The pulleys (17) are preferably made of different sizes
such that although each of the belts (20) moves at a speed different from that of
every other of such belts all the mandrels or spindles (16) shall revolve at approxi-
mately the same speed. When a brush board or stock to be drilled is clamped
between the jaws (o') carried by each pair of brackets (n) and the shaft (5) is
caused to revolve the drills or other boring or drilling tools (18) carried by the
mandrels or spindles (16) will be caused to revolve and when the treadle (14) is
depressed the brush boards or stocks carried by the jaws (o') will be caused to
advance towards and retire from the drills or other boring or drilling tools (18)
and the portions of the said brush boards or stocks which are presented to the
drills or other boring tools (18) will depend upon the position in which the
templet (a) is placed. The stud (a) must be secured in such position in the
in the disc (y) that the required amount of backward and forward motion may be
given to the said brush-boards or stocks. The templet (a) is provided with holes
arranged in accordance with the desired arrangement of the holes in the brush-
boards or stocks to be drilled and is moved by means which we will now proceed to
describe. In a bracket (21) secured to the standard (e) are mounted jaws (22) (23)
which are capable of being slidden upwards and downwards in or upon guides
formed or provided upon the said bracket (21). The construction of the
jaws (22) (23) is clearly illustrated by Figs. 8, 9 and 10 of the accompanying
drawings. The jaw (22) is provided with two parts (22) (22) formed upon a
block (22) each of which parts (22) (22b) is formed with a notch made somewhat
in the shape of a V. As the two notches in the jaw (22) act as one notch we shall
for convenience refer to them as the notch in the jaw (22). The jaw (23) is pro-
vided with a notch made somewhat in the shape of an inverted V and each of such
jaws (22) (23) is so formed as to be a counterpart of the other, the notched part of
the jaw (23) being adapted to pass between the notched parts (22ª) (22) of the
jaw (22). Each of the jaws (22) (23) is formed in two parts one of which is
adapted to bear upon one side of the bracket (21) while the other of such parts is
adapted to bear upon the other side of the bracket (21) and one of the two parts
of the said jaw is secured by set screws to a projection formed upon the other of
such parts and passing through the slot between the guides formed on the said
bracket (21). A connecting rod (24) is secured to the lower jaw (22) by means of
a part of such connecting rod which passes through a lug formed upon the said
jaw and is secured in position therein by means of nuts. The connecting rod (24)
is connected to an arm (25) mounted fast upon an axle (25) capable of being
oscillated in a bracket (26) secured upon the lower surface of the bed (d) of the
machine fast upon which axle (25") is mounted an arm (25) to which is connected
one end of a connecting rod (27) which at its other end is connected to an arm (28)
mounted fast upon an axle (28") capable of being oscillated in a bracket (29)
secured upon the lower surface of the bed (d) of the machine. Fast upon the
axle (28) is also mounted an arm (28) to which is connected one end of a con-
necting rod (30) the other end of which embraces a stud projecting from a
lever (31) capable of being oscillated upon a stud secured in the bracket (2).
The lever (31) is provided with a bowl (31) which is moved in one direction
by means of a cam (32) mounted fast upon the shaft (z), and in the other

page_text: Upon
direction by means of the tension of a spring (31") which is secured at one end
to the arm (28) and at the other end to a bracket (31°) which is secured to
one of the legs (d') of the machine. The bracket (31°) is provided with
a hole through which the connecting rod (30) passes. When the shaft (2) is
caused to revolve the revolution of the cam (31) and the tension of the spring (31)
will cause the axle (28) to be oscillated and cause the jaw (22) to be moved
upwards and downwards. To the connecting rod (24) is secured a bracket (243)
secured in which is a stud (24) which is embraced by one end of a lever (33)
capable of being oscillated on a stud (21) secured in the bracket (21).
A connecting rod (34) part of which passes through a lug formed on the upper
jaw (23) embraces a pin (33) secured in the lever (33). The upward and down-
ward movements of the connecting rod (24) causing the lever (33) to oscillate
cause the jaw (23) to be moved upwards and downwards, the downward movement
of the jaw (23) taking place simultaneously with the upward movement of the
rod (24) and jaw (22) and the upward movement of the jaw (23) taking
place simultaneously with the downward movement of the jaw (22).
the connecting rod (30) a collar (31d) is secured and upon such connecting
rod (30) between the collar (31) and the bracket (31°) are placed a washer
or collar (3) of leather and a washer or collar (31) of india-rubber.
The collar (31) is secured upon the connecting rod (30) in such position that
the washers (31) and (31') of leather and indiarabber will act as a buffer to
arrest the movement of the connecting rod (30) in one direction and prevent the
termination of the downward movement of the jaw (22) from being accompanied
by unnecessary shock. The movements of the jaws (22) (23) are so adjusted that
a pin (35) provided with a handle in order that it may be conveniently manipulated
by the attendant in charge of the machine may having been previously placed in
the space between the sides of the notch of the jaw (22) and the sides of the notch
of the jaw (23) be held between such jaws (22) (23) and in the apexes of the
notches of such jaws (22) (23). The pin (35) shown only in Fig. 6, is shown
removed from the space between the sides of the notches of the jaws (22) (23) for
convenience of illustration. The jaws (22) (23) are preferably secured in such
positions upon the connecting rods (24) (34) respectively that the pin (35) when
held by such jaws (22) (23) shall have its axis in the horizontal plane passing
through the centres of the plates (j) (q). It will be obvious that in whatever
part of the space enclosed between the sides of the notch of the jaw (22) and the
sides of the notch of the jaw (23) the pin (35) may be placed it will as such
jaws (22) (23) are brought together be brought to the apex of each of such
notches. The arrow (A) indicates the direction in which the shaft (5) is caused
to revolve when the machine illustrated in Figs. 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 of
the accompanying drawings, is in use, and the arrow (B) indicates the direction in
which the shaft (c) is caused to revolve by the revolution of the shaft (5) when
the part (7) of the clutch (7) is placed in engagement with the part (7ª) thereof.
The cain (32) is as is indicated in Figs. 1 and 14 so placed in relation to the
groove in the disc (y) that the jaws (22) (23) may have completed their approach
to one another at the time the plates (1) (1) commence to be moved towards the
drills or boring tools (18), and so that the jaws (22) (23) may continue to hold the
pin (35) until the brush-boards or stocks being operated on are withdrawn clear of
the drills or boring tools (18). In order that the templet (a) may be properly
guided by the arms (b) (¹) and in order that the wearing of the templet (a) and
arins (b) (b) may be prevented from interfering with the proper guiding of the
templet (a) by the arms (b) (61) we provide set screws (36) by means of which the
arms (b) may be pressed towards the arms (b') and set screws (37) by means of
which the arms (1) may be pressed towards the arms (b) so that the arms (b) (61)
may be caused to bear upon the templet (a) as closely as may be desirable. The
set screws (36) of which two are employed in conjunction with each arm (b) are
screwed in projecting parts formed on the bracket (21) and the set screws (37) of
which two are employed in conjunction with each arm (6) are secured in
B

page_text: brackets (38) secured to the standard (e). The brackets (38) are omitted from
Fig. 7 in order that confusion may be avoided.
When the machine illustrated in Figs. 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 of the
accompanying drawings is in use and a brush-board or stock to be drilled or bored
has been secured in the jaws or clamps (o¹) carried by each pair of brackets (n)
while the frame formed by the rods (h), arms (j'), bars (m), brackets (n), and
rods (n) is in such a position that the said brush-boards or stocks when secured in
the said jaws or clamps (o¹) are clear of the drills or boring tools and while the
stud (a) is in a position such that it will require to move through more than one
quarter of a revolution in the direction indicated by the arrow (B) before causing
the said brush-boards or stocks to move towards the drills or boring tools (18) and
a templet (a) having formed in it holes arranged in accordance with the desired
arrangement of the holes to be drilled or bored in the said brush-boards or stocks
has been secured to the brackets (ƒ) the pin (35) is inserted into the space enclosed
between the sides of the notches in the jaws (22) (23) when such jaws (22) (23)
are respectively in their lowest and highest positions through one of the several
boles in the templet (a) which may be opposite to the said space. Then the
treadle (14) being depressed the shaft (2) will be caused to revolve and the
jaws (22) (23) will be brought against the pin (35) in the manner above described
and if it be not in the position into which the movement of the jaws (22) (23) is
adapted to bring it will move such pin (35) and also the templet (a) into a position
such that the pin (35) may be held between the deepest parts of the notches in the
jaws (22) (23) in the manner above described. After the templet (a) if not
already in the said position has been moved into it and while the templet (a) is
held in such position the brush-boards or stocks supported by the brackets (n) will
be presented to the drills or boring tools (18) and each be drilled with a hole by
one of such drills or boring tools (18) and then withdrawn therefrom. When the
pin (35) is released by the jaws (22) (23) the attendant in charge of the machine
removing the pin (35) from the hole in the templet (a) in which it was first placed
passes it into the space enclosed between the sides of the notches in the
jaws (22) (23) when such jaws are respectively in their lowest and highest positions
through another hole in the templet (a) which may be opposite to the said space
so that when the jaws (22) (23) are again moved upwards and downwards
respectively into their highest and lowest positions the pin (35) and templet (a)
will be moved thereby so as to move the brackets (f) and cause the rodes (h)
carrying the arms (m) to be so guided that the brush-boards or stocks supporte:1
by the brackets (n) will each be drilled with another hole in the required position.
The attendant in charge of the machine passes the pin (35) into the space between
the sides of the notches of the jaws (22) (23) in the manner above described
through one hole in the templet (a) after another until a hole has been drilled in
each of the brush-boards or stocks being operated upon to correspond with each of
the holes in the templet (a) or with each of any desired number of such hole..
If at any time the attendant in charge of the machine should fail to move the
pin (35) from one hole in the templet (a) to another when the hole corresponding
to the first of such holes has been drilled in each of the brush-boards or stocks
supported by the brackets (n) the said brush-boards or stocks will be again
presented to the drills or boring tools (18) in the position in which they were
previously presented to such drills or boring tools which will thus be caused to
again enter the holes previously drilled or bored by them.
The lateral movement of the templet (a) in either direction from its central
position causes the plate (j) to be turned upon the pin (r) and the upward and
downward movements of the templet (a) from its central position cause the rods (4)
and studs (i) to be turned in relation to the plate (j) and cause the brackets (n) t、
be turned in the bars (m) and thus the holes drilled in the brush-boards or stocks
supported by the brackets (n) will differ in inclination thereto so that a certain
amount of what is termed "spread" will be given to the bristles afterwards inserted
in such brush-boards or stocks.

page_text: The turning of the plate (1) about the stud (r) caused by the templet (a) being
moved laterally from its central position causes the parts of the brush-boards or
stocks which are presented to the drills or boring tools (18) to be moved nearer to
the said drills or boring tools apart from any movement of the stud (15) and as it
is necessary that all the holes in the brush-boards or stocks supported by the
brackets (n) shall be of approximately the same diameter at the backs of such
brush-boards or stocks it is necessary that the distance between the stud (15) and
the portions of the said brush-boards or stocks to be presented to the drilling or
boring tools (18) shall be reduced by an amount corresponding to the distance by
which the portions of such brush-boards or stocks to be drilled or bored are caused
to advance towards the drills or boring tools (18) by the turning of the plate (j)
upon the stud (r). We therefore form the slot (92) in the plate (y) curved so that
as the plate (7) is turned about the stud (r) and turns the plate (g) the stud (15)
will be caused to occupy different positions in the slot (2) so that the distance
between such stud (15) and the stud (r) will be caused to vary according to the
position into which the plate (1) may be turned upon the stud (r). By plates (9)
provided with slots (92) of different forms suitable for use in different cases being
provided in substitution for the plate (9) the distance between the stud (15) and
the portions of the brush-boards or stocks carried by the brackets (n) may be
prevented from being materially varied by the turning of the plate (1) about the
stud (r) caused by the templet (a) used in any particular case being moved into
different positions laterally. The plate (j) is formed with the dovetail pro-
jection (2) in order that different plates (1) may be readily substituted for one
another as may be necessary or desirable from time to time.
Fig. 11 of the accompanying drawings is a side elevation and Fig. 12 a plau
illustrating another form of machine constructed according to this part of our
invention. Certain parts are omitted from Figs. 11 and 12 in order that confusion
may be avoided. The machine illustrated in Figs. 11 and 12 of the accompanying
drawings is adapted to give a greater amount of turning movement to the brush-
boards or stocks being operated upon so that a greater amount of spread will be
given to the tufts of bristles subsequently inserted in the holes drilled or bored in
such brush-boards or stocks. In so far as the parts of the machine illustrated
in Figs. 11 and 12 of the accompanying drawings are similar to the parts of the
machine illustrated in Figs. 1, 2, 3, 4 and 5 of the accompanying drawings we shall
apply to the parts shown in Figs. 11 and 12 the same letters of reference as are
applied to the corresponding parts in Figs. 1, 2, 3, 4 and 5. The machine illustrated
in Figs. 11 and 12 is arranged so that four brush-boards or stocks may be
simultaneously drilled or bored, and in such machine the brush-boards or stocks to be
operated upon are secured in clamps or jaws similar and mounted similarly to the
clamps or jaws (o¹) of the machine illustrated in Figs. 1, 2, 3, 4 and 5 and are
supported by rods (n¹). The two rods (¹) forming each pair of such rods are
cach secured at each end to one of the brackets (n) forming a pair of such
brackets (n). Each of the said brackets (n) is provided with a stud or projection
secured and capable of being oscillated in one of eight arms (45) of which there
are four at each side of the machine although only one side of the machine is shown
in Fig. 11. Each of the arms (45) is capable of being oscillated at one end about
a stud (45) secured by nuts in one of two bars (m) which are mounted and capable of
being oscillated upon studs (46) secured in rods (h) similar to the rods (4) of the
machine illustrated in Figs. 1, 2, 3, 4 and 5 except in so far that the rods (h) of the
machine illustrated in Figs. 11 and 12 are connected directly to the templet (a)
employed in such machine and are made capable of being adjusted in length by being
each formed in two parts secured together by a set screw. The weight of the tem-
plet (a) and rods (h) and the parts supported thereby is counterbalanced by means of
a weight connected to a cord which passes over suitable pulleys and is connected to a
frame (2) connected by set screws to the rods (4). Each of the rods (!) of the
machine illustrated in Figs. 11 and 12 is secured by means of a set screw in one of
two studs (i) each of which is secured and capable of being oscillated in one of two

page_text: arms (¹) projecting from a plate (1) capable of being slidden between plates (k) (k¹)
mounted upon a standard (*) formed in one with the plate (k) and supported by
the bed (d) of the machine. In the machine illustrated in Figs. 11 and 12 the
plate () is formed in two parts the part. (*) being made so as to be capable of
being slidden or oscillated between the plates (k) (¹) and the part (1) which is
capable of being slidden or oscillated horizontally in the part (³). Each of the
parts (j) () of the plate (j) is formed with a number of holes adapted to receive
a stud or studs (39) by which such parts may be connected together either so that
the part () may be turned in relation to the part (5) or so that both of such
parts () () will be caused to move together according to the movement which it
is desired to give to the brush-boards or stocks to be operated upon.
When one
stud (39) is employed to connect the parts (5) (1) of the plate () together as is
indicated in Figs. 11 and 12 the part (6) may be turned about such stud (39) in
relation to the part (j³) and when two studs (39) are employed to connect the
parts () () such parts will move together and act as one plate (j). In Figs. 11
and 12 two studs (r) are shown as being inserted in the part (5) of the plate (j)
and into the slots extending lengthwise of the plates (k) (k¹) which slots act as
guides for such studs (2) so that the part (j³) of the plate (j) can only be moved
backwards and forwards in a straight line, the necessary turning in a horizontal
plane of the brush-boards or stocks being provided for by the parts (j) (*) of the
plate () being only connected together by one stud (39). If only one stud (2) be
placed in the slots of the plates (k) (k) and in the part (") of the plate (j) and
the parts () (6) be connected together by two studs (39) the turning in a
horizontal plane of the brush-boards or stocks being operated upon will take place
about the axis of the stud (r) inserted in the slots of the plates (k) (¹) and the
part (5) of the plate (j). The axis about which the turning in a horizontal plane
of the brush-boards or stocks being operated upon shall take place may be thus
caused to be that of a stud (r) inserted in the slots of the plates (k) (¹) and in the
part () of the plate (j) or that of a stud (39) inserted into the two parts (³) (°) of
the plate (j) as may be desirable from time to time according to the form of the
brush-boards or stocks being operated upon. As in the machine illustrated in
Figs. 1, 2, 3, 4 and 5 the plates (k) (k) of the machine illustrated in Figs. 11
and 12 are secured together by bolts (2) and kept at a suitable distance apart by
<listance pieces (³) and are formed with slots extending lengthwise of the machine.
At its other end each of the arms (45) is capable of being oscillated about a
stud (45) secured in one of the arms (1) projecting from the plate (j). Each of
the brackets (n) is provided with an arm (n2) which being secured upon the stud
projecting from such bracket secures it in the arm (45) in which it is mounted. In
the arm (2) of each bracket (n) are formed guides between which may be slidden
a block capable of being oscillated upon a stud secured in one of a number of
rods (47) which are respectively capable of being_secured in various positions as
may be desirable from time to time in sockets (48) formed on the arms (j')
projecting from the plate (j). In each of the rods (4) is mounted a bracket (49*)
which is capable of being oscillated in the rod () in which it is mounted and
extending between the brackets (49") is a rod (1) which at its ends is connected to
blocks capable of being adjusted in position in the brackets (49") by means of
screws (49). The said rod (1) supports a stop plate (42) such as will be herein-
after described in reference to a further part of our invention. Each of the
brackets (49) is provided with an arm (49) in which are formed guides between
which may be slidden a block capable of being oscillated upon a stud projecting
from one of two rods (50) which are respectively capable of being secured in
various positions as may be desirable from time to time in sockets (51) formed in
the arms () projecting from the plate (j). By the rods (50) being adjusted into
proper position the brackets (49) may be caused to oscillate to the same extent
as the brackets (n) when the rods (h) are raised or lowered and by means of
the screws (49), and similar screws which are not shown in the accompanying
drawings each of which is mounted in a block provided in one of the brackets (n)

page_text: and capable of being turned to adjust one part of such bracket (») in position in
relation to the other parts thereof the distance of the stop plate (42) and the
brush-boards or stocks being operated on from the axes about which they are
respectively oscillated may be adjusted as may be necessary or desirable. When
the templet (a) is raised or lowered the rods (h) being turned about the axes of the
eyes () and the bars (m) being raised and lowered the arms (45) will be oscillated
about the axes of the studs (45) (45) and the oscillation of the arms (45) causing
the brackets (n) to be moved in relation to the rods (47) the blocks which are
capable of being oscillated upon the studs respectively projecting from such rods (47)
and engage with the guides formed in the arms (n²) of such brackets () will cause such
brackets (n) to be oscillated in relation to the arms (45) so that the turning of the
arms (45) brought about by the raising and lowering of the templet (a) will cause
the brackets (n) and the brush-boards or stocks supported thereby to be oscillated to
a greater extent than the arms (45). The extent of the oscillation of the
brackets (n) and the brush-boards or stocks supported thereby may be varied by
the rods (47) being adjusted longitudinally into different positions in relation to the
brackets (n). The templet (a) in the machine illustrated in Figs. 11 and 12 is
arranged to be moved by the attendant in charge of the machine and is provided
with holes arranged in a suitable manner which are placed or guided one after
another on to a pin or guide (52) carried by a standard (e) mounted upon the bed (d)
of the machine. The drills or boring tools (18) in the machine illustrated in
Figs. 11 and 12 are mounted and driven in the same manner as the drills or boring
tools (18) in the machine illustrated in Figs. 1, 2, 3, 4 and 5. The depth of the
holes bored or drilled in the brush-boards or stocks supported by the brackets (n)
or the extent to which the drills or boring tools (18) are caused to penetrate the
said brush-boards or stocks is regulated by the stop plate (42) supported by the
rod (1) which will be hereinafter further described and which is made of a form
corresponding to that of the brush-boards or stocks being operated upon and is
caused by the arms (49) and rods (50) to be turned in a manner corresponding to
that in which the said brush-boards or stocks are turned so that the position of the
said stop plate (42) will always correspond with that of the brush boards or stocks
being operated upon. The backward and forward movements of the rods (4) and
plate () necessary to present and withdraw the brush-boards or stocks being
operated upon to and from the drills or boring tools (18) in the machine illustrated
in Figs. 11 and 12 are arranged to be obtained by the templet (a) being moved
backwards and forwards by the attendant in charge of the machine as the turning
of the brush-boards or stocks being operated upon caused by the upward and
downward movements of the templet (a) renders it difficult to arrange for the
requisite backward and forward movements of the said brush-boards or stocks to be
produced mechanically.
We would have it understood that if it be considered preferable in any case the
machine illustrated in Figs. 1, 2, 3, 4 and may be provided with a templet
mounted and moved vertically and laterally by hand like the templet (a) illustrated
in Figs. 11 and 12 and that in such case if the stud (15) be removed from the
plates (s) and the plate (g) the backward and forward movements and the lateral
turning of the plate () and the brush-boards or stocks supported by the jaws (o')
may be all accomplished by the said templet being moved by hand.
When a machine of the kind illustrated in Figs. 1, 2, 3, 4, and 5 is provided
with a templet mounted and moved vertically and laterally by hand like the
templet (a) illustrated in Figs. 11 and 12, the backward and forward movements of
the brush-boards or stocks being operated upon may when accomplished by means
of the movements of the stud (r) be limited by the position in which such stud (a)
is secured in the disc (y) and in cases in which machines constructed according to
this part of our invention are provided with templets moved backwards and
forwards and laterally and vertically by hand as in the machine illustrated in
Figs. 11 and 12 the forward movement of the templet may be limited by means of
a stop surrounding the pin (52) as in the machines illustrated in the drawings

page_text: accompanying the Specification filed in respect of the application of the above
named George Shaw, Thomas Shaw and John Peter Ditchfield for Letters
Patent, No. 13639, dated September 21st, 1888 in which case the plate (42) above
mentioned and to be hereinafter further described may be dispensed with.
Our invention consists secondly in improvements in appliances for regulating the
depth of the holes drilled by means of machines of the kind above mentioned.
According to this part of our invention we provide the templet employed in
the machine to which this part of our invention is applied with a plate of
suitable size connected in any suitable manner to the said templet and made and
arranged so that it can be adjusted and secured by means of a screw or nut or
screws or nuts or other devices in any suitable position in relation to such templet
and provide a stud or stop which may be adjusted and secured by a screw or out or
screws or nuts or other devices in any suitable position in a stationary part of such
machine so that by the said plate or the said stud or stop or such plate and stud or
stop being adjusted into and secured in a suitable position or positions the extent to
which the templet above mentioned may be moved in one direction may be limited
as may be necessary. In conjunction with the said templet there is employed
as in machines of the kind described in the Specification hereinbefore mentioned
a pin or equivalent device upon or into engagement with which the templet
eniployed is placed from time to time in order that the drilling of the holes in
the boards or stocks in the positions and at the inclinations desired may be ensured.
This part of our invention is illustrated in Figs. 11 and 12 of the accompanying
drawings, in which (42) is the plate with which we provide the templet (a).
The plate (42) is secured by means of screws (43) provided with lock nuts to the
bar (1) above mentioned. The screws (43) and the lock nuts on the screws (43)
enable the plate (42) to be adjusted into and secured in position in relation to
the bar (1) and in relation to a stud (44) which being omitted from Figs. 11 and 12
in order that confusion may be avoided is indicated in Fig. 4 and is mounted so as
to be capable of being adjusted endwise in the standard (c) mounted upon the
bed (d) of the machine and is capable of being secured in position therein by
means of a lock nut. The plate (42) is mounted upon the bar (1) in such position
that when the rods () are in a horizontal position and at equal distances from the
vertical plane containing the axes of the drills or boring tools (18) the central
portion of the plate (42) shall be in line with the axis of the stud (44) which is in
the same vertical plane as the axes of the drills (18). The plate (42) is also
adjusted into and secured in such position that its front surface shall be in the same
vertical plane as or in a vertical plane at a suitable distance from the backs of the
brush-boards or stocks mounted in the jaws or clamps upon the rods (n¹) and the
drills or boring tools (18) are so made and mounted that their points shall all be in
one vertical plane. In consequence of being mounted and adjusted in position in
the said manner the plate (42) is moved similarly to and to the same extent as
the brush-boards or stocks supported upon the rods (n') and by arriving against the
stud (44) in the forward motion of the said brush-boards or stocks limits the
forward movement of the brush-boards or stocks and thus regulates the extent
to which the drills or boring tools (18) may be caused to enter the said brush-
boards or stocks. The plate (42) is made to correspond in form with the
brush-boards or stocks being operated upon and being moved similarly to such
brush-boards or stocks renders it possible to ensure that all the holes drilled or
bored in such brush-boards or stocks shall penetrate or pass through such brush-
boards or stocks to approximately the same extent although the brush-boards or
stocks may vary somewhat in thickness. In the machine illustrated in
Figs. 1, 2, 3, 4, 5 and 6 in which the employment of the plate (9) with the
curved slot (92) and the rigid connection of the connecting rod (1) with the
block (s) and the adjustment and securing of the stud (r) in proper position in
the disc (y) ensure that the requisite amount of motion shall be given to the
plates (g) () by the revolution of the stud (r) a plate (42) similar to the
plate (42) above described in reference to Figs. 11 and 12 is shown as being

page_text: employed and mounted upon the bar (1) of the machine illustrated in
Figs. 1, 2, 3, 4 and 5 and employed in conjunction with a stud (44) mounted and
capable of being adjusted in the standard (c) of such machine similarly to the
stud above described as being employed in conjunction with the plate (42) shown
in Figs. 11 and 12. The plate (42) in the machine illustrated by Figs. 1, 2, 3, 4 and 5
being adjusted in position similarly to the plate (42) above described in reference
to Figs. 11 and 12 will by tending to prevent the frame formed by the arms or
bars (m), arms (j'), rods (^), bar (1), brackets (n) and rods (n) from being
distorted by the drills or boring tools (18), if in the form of twist drills, screwing
themselves into the holes tend to prevent such drills or boring tools (18) from
unduly entering the brush-boards or stocks being bored or drilled.
Although illustrated in the accompanying drawings as applied to machines in
which several brush-boards or stocks are simultaneously subjected to the action of
distinct drills by the use of one templet the plate (42) and stud or stop (44) may
be applied to machines of the kind described in the Specification filed in respect of
the application of the above named George Shaw, Thomas Shaw and John Peter
Ditchfield No. 13639, dated September 21st, 1888 with the same advantage as to.
the machine illustrated in Figs. 11 and 12 of the accompanying drawings.
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:-
