Improvements in Machinery or Apparatus for the Manufacture of
Certain kinds of Brushes or 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 the manufacture of certain kinds of brushes and brooms
and consists in arrangements of apparatus by means of which we are enabled to bore
or drill with greater facility and accuracy of position than heretofore the holes in the
boards or stocks for the reception of the tufts of bristles, fibre, bass or other material
of which the brush or broom is composed.
According to the first part of our invention we employ a templet secured to arms
which are capable of being moved longitudinally through sockets formed in a bar
hinged or jointed to a plate or slide-bar in which are formed holes in any one of which
a pin or stud may be placed. The arms before mentioned may be secured in any
desired position in the sockets through which they pass by means of set screws or
equivalents therefor. The plate or slide-bar above mentioned passes between fixed
plates or guides in each of which is formed a slot through which and through a hole
in the plate or slide bar before referred to passes the pin or stud above mentioned.
The plates aforesaid act as guides to prevent the plate or slide-bar from rotating and
leave such plate or slide-bar at liberty to be turned upon the pin or stud while the said
plate or slide-bar is being moved longitudinally between the fixed plates above
referred to. Secured to or formed upon the arms before mentioned are brackets
capable of revolving in and supported by which are shafts upon which are formed
right-hand screw-threads and left-hand screw-threads. The said right-hand screw-
threads and left-hand screw-threads by means of suitable jaws cause the brush-board
or stock to be secured or held while being operated upon. To the framework of the
machine between the place where the brush-board or stock is placed while being
operated upon and the templet above referred to we fix a head-stock in which is
mounted a rotating spindle which carries the drill employed to form the holes in the
brush-board or stock to be operated upon. Projecting from a bracket secured to the
framework of the machine and in front of the templet previously referred to is a pro-
jecting stud or pin. In the templet above mentioned we form boles corresponding in
position and arrangement to the holes to be formed in the brush-board or stock to be
operated upon. The brush-board or stock to be operated upon is secured to the arms
above mentioned by means of the screws and jaws above referred to.
The attendant then places one of the holes in the templet upon the projecting stud
or pin above mentioned and draws or slides the templet along such stud or pin. The
movement of the templet and parts connected thereto will cause the brush-board or
stock to be operated upon by the drill, the depth of the hole drilled being regulated by
a stop. The templet above mentioned may contain as many holes as are to be formed
or drilled in the brush-board or stock or the templet may only contain holes corre-
sponding in position and arrangement to a portion of the holes to be formed in the
brush-board or stock the remaining holes in the brush-board or stock being formed by
a subsequent operation.
In drilling or forming the holes in brush-boards or stocks of a rounded or curved
form we secure the brush-board or stock to be operated upon between jaws which
may be placed at an angle or rotated or we mount the brush-board or stock between
supports one or both of which may be placed at an angle or rotated. We cause the
amount of turning or rotation imparted to the brush-board or stock to be detirmined

page_text: by means of a dividing disc or plate provided with a suitable catch by means of which
the dividing disc or plate or brush-board or stock is prevented from being turned
except when required.
By the brush-board or stock being placed nearer to or farther from the templet or
by the pin above mentioned which slides in the slot above referred to being placed
nearer to or farther from the brush-board or stock the angle or divergence of the holes
may be made greater or less as may be desired.
According to another arrangement of our invention we employ a frame and templet
similar to that above mentioned which frame is provided with a cross-bar which is
capable of being moved upon a flat bar in which are formed a number of holes. The
bar and the flat bar above mentioned are secured together by means of a pin which
passes through a hole in the bar and one of the holes formed in the flat bar above
mentioned. The flat bar above mentioned is jointed or hinged to a bar or plate
capable of being slidden longitudinally between guides secured to the framework of
the machine.
A further portion of our invention consists in apparatus by means of which we are
enabled to bore or drill the brush-boards or stocks in which it is desired that the holes
bored or drilled in such brush-boards or stocks shall have a considerable amount of
angle or divergence.
In the frame or arm to which the templet previously referred to is secured we mount
a bar or shaft a portion of which is formed with a hollow or cavity in which the brush-
board or stock to be drilled or bored is placed and secured thereto by means of a
.screw and suitable clamps and jaws. Fast upon the bar or shaft is mounted a toothed
sector the teeth of which gear into the teeth of a toothed sector mounted fast upon
the slide or bar upon which turns the arm or frame to which is secured the templet
and the brush-board or stock to be operated upon.
When the arm or frame is moved into the position required when drilling the holes
along the sides of the brush-board or stock such moving of the arm or frame will
by means of the toothed sectors cause the shaft or bar to which the brush-board
or stock is secured to be turned a portion of a revolution thereby causing the holes
drilled or bored to have a considerable amount of angle or divergence. The angle
or divergence of the holes drilled or bored in the brush-board or stock may be
increased or diminished by employing toothed sectors of suitable radius. This
arrangement of our invention is particularly applicable for use in drilling or boring
holes in the brush-boards or stocks in which a considerable degree of angle or
divergence of the holes is required.
According to a further part of our invention we employ a frame provided with a
templet as above described. In one end of each of the arms of such frame are
formed holes which are passed upon a bar or rod or bars or rods formed upon or
secured to a plate or bar capable of being slidden longitudinally between guides
secured to the framework of the machine. The frame above mentioned is capable
of being turned upon the bar or rod or bars or rods before mentioned and may
also be slidden longitudinally upon the said bar or rod or bars or rods.
This arrangement of our invention is particularly applicable to brush-boards or
stocks in which the rows across the width have a slight amount of angle or divergence
and in which the rows lengthwise of the brush-boards or stocks are parallel.

Improvements in Machinery or Apparatus for the Manufacture of
Certain kinds of Brushes or 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

page_text: what manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
Our Invention relates to the manufacture of certain kinds of brushes and brooms
and consists in arrangements of apparatus by means of which we are enabled to bore
or drill with greater facility and accuracy of position than heretofore the holes in the
boards or stocks for the reception of the tufts of bristles, fibre, bass or other material
of which the brush or broom is composed.
According to the first part of our Invention we employ a templet secured to
arms which are capable of being moved longitudinally through sockets formed in a
bar hinged or jointed to a plate or slide-bar in which are formed holes in any one
of which a pin or stud may be placed. The arms before mentioned may be secured
in any desired position in the sockets through which they pass by means of set
screws or equivalents therefor. The plate or slide-bar above mentioned passes
between fixed plates or guides in each of which is formed a slot through which
and through a hole in the plate or slide-bar before referred to passes the pin or
stud above mentioned. The plates aforesaid act as guides to prevent the plate or
slide-bar from rotating and leave such plate or slide-bar at liberty to be turned
upon the pin or stud while the said plate or slide-bar is being moved longitudinally
between the fixed plates above referred to. Secured to or formed upon the arms
before mentioned are brackets capable of revolving in and supported by which are
shafts upon which are formed right hand screw-threads and left hand screw-threads.
The said right hand screw-threads and left hand screw-threads by means of suitable
jaws cause the brush-board or stock to be secured or held while being operated
upon. To the framework of the machine between the place where the brush-board
or stock is placed while being operated upon and the templet above referred to we
fix a head-stock in which is mounted a rotating spindle which carries the drill
employed to form the holes in the brush-board or stock to be operated upon.
Projecting from a bracket secured to the framework of the machine and in front
of the templet previously referred to is a projecting stud or pin. In the templet
above mentioned we form holes corresponding in position and arrangement to the
holes to be formed in the brush-board or stock to be operated upon. The brush-
board or stock to be operated upon is secured to the arms above mentioned by
means of the screws and jaws above referred to. The attendant then places one of
the holes in the templet upon the projecting stud or pin above mentioned and draws
or slides the templet along such stud or pin. The movement of the templet and
parts connected thereto will cause the brush-board or stock to be operated upon by
the drill the depth of the hole drilled being regulated by a stop. The templet
above mentioned may contain as many holes as are to be formed or drilled in the
brush-board or stock or the templet may only contain holes corresponding in position
and arrangement to a portion of the holes to be formed in the brush-board or
stock the remaining holes in the brush-board or stock being formed by a subsequent
operation.
The tufts of bristles, fibre, bass or other material of which the brush or broom is
composed we shall for convenience hereinafter refer to as the tufts of bristles.
Our invention is illustrated in the accompanying drawings in the various figures of
which we shall apply to corresponding parts the same letters of reference.
In the accompanying drawings Fig. 1 is a plan and Fig. 2 a side view of one of the
machines constructed according to our invention.
.
According to the first part of our invention we employ a templet a secured to
arms al which are capable of being moved longitudinally through sockets 61 formed in
a bar hinged or jointed by a rod c to a plate or slide-bar d in which are formed
holes in any one of which a pin or stud e may be placed. The arms a may be
secured in any desired position in the sockets &¹ by means of set-screws or equivalents
therefor. The plate or slide-bar d passes between fixed plates or guides f in each of
which is formed a slot f¹ through which and through one of the holes d' is passed the

page_text: pin or stud e.
The plates or guides fact as guides to prevent the plate or slide-
bar d from rotating and leave such plate or slide-bar d at liberty to be turned
horizontally upon the pin or stude while the plate or slide-bar d'is being moved
longitudinally between the plates or guides f.
The plates or guides are secured together by means of the screws f2 which
pass through washers or thimbles by which the plates or guides fare prevented
from binding upon the plate or slide-bar d. Secured to or formed upon the arms a¹
aro brackets a carried by which and capable of being revolved therein are shafts g
upon each of which are formed right-hand screw-threads g¹ and left hand screw-
threads g. Mounted upon the shafts 7 and acted upon by the screw-threads g', gª
are jaws which may vary in form and size according to the shape of the board
to be held by them. The shafts g are geared together by means of wheels 7³ so that
when one of the shafts g is turned by means of the handle g the other shaft g will
also be turned. The brush-board or stock to be operated upon is placed between the
jaws and the handle 9 being turned the screw-threads g¹² will cause the said
brush-board or stock to be firmly held between the jaws h. The right hand screw-
threads g and left hand screw-threads g* cause each brush-board or stock being
operated upon to be held midway between the arms at although the brush-boards or
stocks may not be of an uniform length. To the framework or bed j of the machine
and between the brush board or stock being operated upon and the templet a we fix a
head-stock in which is mounted a rotating spindle which carries the drill m
employed to form the holes in the brush-board or stock to be operated upon.
Projecting from a bracket n secured to the framework j of the machine and in front
of the templet a is a projecting pin or stud o. In the templet a we form holes A as
shown in Fig. 3 which is a front view. of the templet a. The holes A correspond in
position and arrangement to the holes to be formed or drilled in the brush-board or
stock to be operated upon. The brush-board or stock to be operated upon is secured
to the arms a¹ by means of the screws and jaws h. The projecting pin or stud o is
so adjusted by the nuts o¹ and screw-threads or by the bracket n being moved upon
the framework j that when one of the holes A formed through the templet a is placed
upon the projecting pin or stud o and slidden longitudinally thereon in the direction
indicated by the arrow B such pin or stud o will act as a guide and support for the
templet a.
•
m is a stop formed with a shank m² which passes through a hole formed in the
headstock and may be secured therein by means of a set-screw m³. The stop m¹ is
so adjusted relatively to the point of the drill m that when the surface of the brush-
board or stock arrives against the stop m² the hole drilled in such brush-board or
stock will be of the depth required.
The attendant places one of the holes A in the templet a upon the projecting pin
or stud o and draws or slides the templet a along the stud or pin o.
The movement of the templet a and the parts connected thereto will cause the
brush board or stock to be operated upon by the drill m the depth of the hole formed
in the brush-board or stock being regulated by the stop m¹. The attendant repeats
the above described operation until the desired number of holes has been drilled in the
brush-board or stock and then turning the handle g₁ releases the brush-board or stock
and replaces it by another to be operated upon.
The templet a may contain as many holes A as are to be formed or drilled in the brush-
board or stock or the templet a may only contain holes corresponding in position and
arrangement to a portion of the holes to be formed in the brush-board or stock, the
remaining holes in the brush-board or stock being formed by a subsequent operation.
The slots fallow the templet a and parts connected therewith to be moved in the
direction of the length of the machine.
The templet a arms a' and jaws h and the brush board or stock being operated
upon can be turned upon the rod c as indicated by the dotted lines in Fig. 2.
The movement of the arms a¹ upon the pin or stude and upon the rod c will cause
the holes drilled in the brush board or stock to be drilled at an angle in order that

page_text: the required spread” may be given to the bristles or other fibre or material subse-
quently inserted in the holes formed in the brush-board or stock. When the pin or
stud e is placed in a hole farther away from the templet a the holes drilled in the
brush-board or stock will be drilled more nearly parallel to each other than when the
pin or stude is placed in a hole d' nearer to the templet a.
By the set-screws & being slackened and the templet a and jaws h being adjusted
in position so as to be farther from the axis of the rod e the holes drilled in the brush-
board or stock will be drilled more nearly parallel to each other in planes at right-
angles to the rod e than when the templet a and jaws h are placed nearer to the axis
of the rod c. By the templet a and jaws h being adjusted in position so as to be
nearer to or farther from the axis of the rod c and the pin or stud e being placed in
one or other of the holes d', holes may be caused to be so drilled or formed in the
brush-board or stock as to give a greater or less amount of "spread" to the bristles,
bass or other fibre forming the brush or broom as may be desired. The machine
illustrated by Figs. 1 and 2 is intended to be employed for drilling brush-boards or
stocks in which the holes require to have only a small degree of "angle ог
divergence.
"
Figs. 11 and 1° show the form of brush-board or stock in the drilling of the
holes in which the machine shown in Figs. 1 and 2 is required.
In drilling or forming tlie holes in brush-boards or stocks of a rounded or curved
form we secure the brush-board or stock to be operated upon, between jaws which
may be placed at an angle or rotated or we mount the brush-board or stock between
supports one or both of which may be placed at an angle or rotated. We cause the
amount of turning or rotation imparted to the brush-board or stock to be determined
by means of a dividing disc or plate provided with a suitable catch by means of which
the dividing disc or plate or brush-board or stock is prevented from being turned
except when required.
By the brush-board or stock being placed nearer to or farther from the templet or
by the pin above mentioned which slides in the slot above referred to being placed
nearer to or farther from the brush-board or stock the "angle" or divergence of the
holes may be made greater or less as may be desired.
A machine arranged for performing this portion of our invention is illustrated by
Figs. 4 and 5 of the accompanying drawings. Fig. 4 being a side elevation and Fig. 5
a plan of that which is shown in Fig. 4.
As certain parts of the machine illustrated by Figs. 4 and 5 are similar in construc-
tion and operation to some of the parts shown in Figs. 1 and 2 we shall apply to such
parts the same letters of reference as are applied to the corresponding parts in Figs. 1
and 2. The machine illustrated in Figs. 4 and 5 is especially arranged for drilling
the holes to receive the bristles fibre bass or other material of which the brush or
broom is formed; in circular or cylindrical brushes or brooms in which the surface
in which the bristles, fibre, bass or other material are or is secured, is circular or of
a circular section. Secured to the plate or slide-bar d are brackets pop². Carried
by the bracket p¹ and capable of being rotated therein is a spindle r. Fast upon the
spindle is a cup having projecting from its surface pins or spikes.
7°
"
Fast upon the spindle is a toothed wheel. Secured to the bracket p¹ is a
stud p² and mounted upon such stud p² is a click or catch p³. The wheel and
click or catch p³ constitute a dividing apparatus." Fast upon the spindle is a
handle by which the spindle may be turned. Carried by and free to be turned
in the bracket p is a screwed spindles which is provided with a handle ¹ by means
of which the spindle s may be turned. The spindle is formed with a conical
point s².
The brush-board or stock to be operated upon is placed between the cup r¹ and the
point 8. The screwed spindles is then turned by means of the handles so that the
brush-board or stock will be firmly held between the points and the pins or spikes
with which the cup is provided. The cup assists in holding the brush-board or
stock in the "true" position for being operated upon. Through the templet a are
formed holes A corresponding in arrangement with the holes to be drilled in the brush

page_text: board or stock to be operated upon. After one row of holes extending in the direction
of the length of the brush-board or stock has been drilled, the click or catch p³ is
raised clear of the teeth of the wheel and the spindle and brush-board or stock
are turned by means of the handle 3 through the angular distance necessary to bring
the brush-board or stock into the required position for having another row of holes
formed therein. When the brush-board or stock has been turned to the desired
position it is retained therein by the click or catch p³. In those cases in which the
inachine is to be employed for drilling the holes in brush-boards or stocks of a semi-
circular section such as is shown in Fig. 6 the brush-boards or stocks may be secured
together back to back in pairs as shown in Fig. 7 so that two of such semi-circular
brush-boards or stocks may be drilled as one circular brush in which form they are
drilled more readily and cheaply than they would be separately.
According to another arrangement of our invention we employ a frame and templet
similar to that above mentioned which frame is provided with a cross-bar which is
capable of being moved upon a flat bar in which are formed a number of holes. The
bar and the flat bar above mentioned are secured together by means of a pin which
passes through a hole in the bar and one of the holes formed in the flat bar above
mentioned.
The flat bar above mentioned is jointed or hinged to a bar or plate capable of being
slidden longitudinally between guides secured to the framework of the machine.
A machine constructed according to this arrangement of our invention is shown in
Figs. 8 and 9 of the accompanying drawings. Fig. 8 is an elevation and Fig. 9 a plan
of a machine constructed according to our invention and particularly adapted for
drilling the "end holes" of certain brush-boards or stocks, which holes require to be
drilled at a considerable angle to the other holes drilled in the brush-board or stock
and also require to have a considerable amount of "angle" divergence or "spread."
Figs. SA SB SC serve to indicate the class of holes in the drilling of which the
machine shown in Figs. 8 and 9 is required. To such of the parts shown in Figs. 8
and 9 as correspond to parts shown in Figs. 1. 2. 4 and 5 we shall apply the same
letters of reference as are applied to the corresponding parts in Figs. 1. 2. 4
and 5.
The arms a carrying the templet a pass through sockets formed upon a bar or
frame capable of being turned horizontally upon a flat bar or plate d² to which the
bar or frame b is jointed by means of a pin 3 which is passed through one of a series
of holes d' formed in the flat bar or plate d
hinged by means of a rod c to a bar or plate d
between guides t secured to a bracket t'
machine.
The flat bar or plate is jointed or
capable of being slidden longitudinally
secured to the framework of the
Supported by the arms a' is a shaft upon which are formed right hand
screw-threads and left hand screw-threads 2 upon which are mounted jaws h.
Passing through the jaws is a bar upon which are formed collars ¹. The
ends of the bar v pass through curved slots formed in parts each formed on one of
the arms a¹.
ย
The bar is provided with nuts 3 by means of which its ends may be secured in
any desired position in the slots v².
ย
The nuts being slackened the jaws and bar are turned around the shaft u
until the jaws h are in the position for presenting the brush-board or stock to be
operated upon; in the required position to the drill m. The bar is then secured in
the slots by means of the nuts 3. The face of the templet a is placed at an angle
to the bar and parallel or nearly so to the portion of the brush-board or stock in
which holes are to be drilled. By mounting the jaws over or nearly over the pin ³
upon which the bar or frame 6 turns and placing the rod e by which the flat bar or
plate dis hinged or jointed to the bar or plate d near to the pin 3 we are enabled to
obtain the divergence or "spread" of the holes which is necessary to give the required
degree of divergence or "spread" to the tufts of bristles placed in the extremity or
extremities of certain kinds of brushes or brooms such for instance as stove-brushes,
scrubbing-brushes and brooms.

page_text: A further portion of our invention consists in apparatus by means of which we are
enabled to bore or drill the brush-boards or stocks in which it is desired that the holes
bored or drilled in such brush-boards or stocks shall have a considerable amount of
"angle" or divergence. In the frame or arm to which the templet previously referred
to is secured we mount a bar or shaft a portion of which is formed with a hollow or
cavity in which the brush-board or stock to be drilled or bored is placed and secured
thereto by means of a screw and suitable clamps and jaws. Fast upon the bar or
shaft is mounted a toothed sector the teeth of which gear into the teeth of a toothed
sector mounted fast upon the slide or bar upon which turns the arm or frame to
which is secured the templet and the brush-board or stock to be operated upon. When
the arm or frame is moved into the position required when drilling the holes along
the sides of the brush-board or stock such moving of the arm or frame will by means
of the toothed sectors cause the shaft or bar to which the brush board or stock is
secured to be turned through a portion of a revolution thereby causing the holes
drilled or bored to have a considerable amount of "angle" or divergence. The "angle"
or divergence of the holes drilled or bored in the brush-board or stock may be increased
or diminished by employing toothed sectors of suitable radius.
Figs. 10 and 11 show a machine constructed according to this portion of our
invention, Fig. 10 being an elevation and Fig. 11 a plan of that which is shown in
Fig. 10. Figs. 10A and 10 show the form of brush board or stock in the drilling of
the holes in which the machine shown in Figs. 10 and 11 is required. As parts of
the machine shown in Figs. 10 and 11 are similar in construction and operation to
parts of machines hereinbefore described, we shall apply to such parts the same letters
of reference as have been applied to the corresponding parts hereinbefore described
and shall not describe such parts further than may be necessary in describing the
construction and operation of the other parts used in conjunction therewith.
Upon the arms a to which is secured the templet a, are formed bosses w passing
through which and capable of being turned therein is a shaft upon which shaft are
formed or secured brackets x. Carried by the brackets and capable of being
rotated therein are shafts g upon which are formed right hand screw-threads g' and
left hand screw-threads g. Upon the screw-threads g¹ g² and acted upon thereby are
jaws or clamps h. Fast upon one end of each of the shafts g is a toothed wheel gå
which gears into a wheel g* mounted so as to be free to turn on the shaft x.
Fast upon one of the shafts g is a handle gt. By the said shaft g being turned by
means of the handle g' motion will by means of the wheels g³ g³× 93 be transmitted to
the other shaft g and the jaws or clamps h may be caused to approach towards or
recede from each other. Fast with the plate or slide-bar d are arms d³ mounted upon
which and free to turn thereon are steps d'. In the arms a' are formed slots a² in
which are situate the steps d' upon which the slots a² may at times be slidden by
means of screws a passing through the arms a'. Fast upon the arms d'are wheels
which gear into wheels fast upon the shaft a. When the templet a and arms a¹ are
turned upon the arms d³ the wheels, shaft a and brackets will be turned through
a portion of a revolution around the axis of the shaft so that the holes drilled in the
brush-board or stock will be caused to have a considerable "angle" or divergence.
The divergence of the holes drilled or bored in the brush-board or stock may be
increased or diminished by employing toothed wheels, y of suitable diameter the
arms being adjusted in relation to the shaft as may be necessitated by the
diameters of the wheels ², y placed upon the shaft æ and arms d³. For convenience
of construction we place toothed wheels such as a³, y upon the shaft and arms d³ the
operative portions of such wheels constituting toothed sectors but. if desired toothed
sectors may be employed in place of the toothed wheels a², y.
Fig. 12 is a plan and Fig. 13 an elevation of another arrangement of machine
constructed according to this portion of our invention. In Figs. 12 and 13 to parts
corresponding to those above described are applied the same letters of reference as
are applied to the corresponding parts above described.
d is a plate or slide-bar capable of being slidden between the fixed plates f
Edgewise through the plate or slide-bar d is formed a slot d³ situate in which and

page_text: capable of being turned horizontally therein is a plate or bar . Through the plate
or slide-bar d are formed holes in any one of which is placed a pin 1. capable of being
slidden in a slot f* formed in one of the fixed plates. Through the plate or bar =
are formed holes in any one of which a pin may be placed. Formed upon the
plate or bar are arms upon which are formed projecting parts through which are
screwed set-screws 2 the ends of which form pivots upon which the arms a¹ may be
turned. To the arms a¹ is secured the templet a. Carried by the arms a' and capable
of being turned therein are short spindles 3 in each of which is formed a box 4 into
which passes one end of a stud 5 projecting from a bracket 6. Carried by the
brackets 6 and capable of being turned therein are shafts upon cach of which are
formed right hand screw-threads g₁ and left hand screw-threads g². Mounted upon
and acted upon by the screw-threads g¹, g² are jaws h. Fast upon each of the
shafts g is a wheel g³ which gears into a wheel ** mounted loose upon one of the
studs 5. By means of the handle g* fast upon one of the shafts the shafts g may
be turned. Fast upon each of the spindles 3 is an arm 7 in which is formed a slot.
Upon the arms 23 are formed bosses S through each of which passes a rod 9. Upon
each of the rods 9 are formed screw-threads. The rods 9 are capable of being
adjusted longitudinally in the bosses 8 and after adjustment may be secured in
position by means of nuts 9". Each of the rods 9 is provided with a pivot 10 which
projects into the slot formed in one of the arms 7 fast upon one of the spindles 3.
When the arms a¹ and templet a are turned upwards or downwards upon the pivots
formed by the set-screws 2 the movement of the arms a¹ and templet a will cause
one side or the other of the slot in each of the arms 7 to arrive against the pivot 10
projecting into such slot and thereby cause the spindles 3 to be turned. By
adjusting the rods 9 by means of the nuts 9" so that the studs 10 are nearer to or
farther from the axes of the spindles 3 the spindles 3 may be caused to be turned
in a greater or less degree by a given movement of the arms a¹ and templet a and
the divergence of the holes drilled in the brush-board or stock, across the width of
the brush-board or stock may be made greater or less as may be desired. Fig. 14
is a view of certain parts illustrating the manner in which the position of the brush-
board or stock is changed by the templet a being depressed.
The arrangement of machine shown by Figs. 12 and 13 is particularly applicable
for drilling the holes in brush-boards or stocks having the form shown in the
detached view Fig. 15.
When the holes in the portion of the brush-beard or stock between the points B
and Care being drilled the arms are fixed to the plate or slide-bar d by the
pin and a pin passed through one of the holes in the plate or slide-bar d the
plate or slide-bar d being then free to move upon the pin 1 situate in the slot f* and
one of the holes formed in the plate or slide-bar d.
When the holes in the portion of the brush-board or stock between the points C
and Dare to be drilled another pin 1 is passed through the slot and into one of
the holes formed in the plate or slide-bar d so that the plate or slide bar d can only
be moved in the direction of its length and the plate or bar is secured to the plate
or slide-bar d by means of one pin passed through one of the holes in the
plate or slide-bar d and one of the holes in the plate or bar z, the pin being
removed.
By the arrangement of machine shown in Figs. 12 and 13 we are enabled to drill
the holes in a brush-board or stock so that the holes in one portion of the brush-
board or stock will have a greater or less degree of divergence than the holes in
another portion of the brush-board or stock.
Fig. 16 shows one method of holding in position while being drilled
brush-boards or stocks of a form such as that shown at E and of forms
similar thereto. To bars h which are caused. to approach towards or recede
from each other by the right hand screw-threads g' and left hand screw-
threads g we secure plates which plates in conjunction with the bars h form
angular recesses ² as shown in Fig. 17, which angular recesses when the bars h
are caused to approach each other retain the brush-board or stock to be operated upon

page_text: in position while being drilled. The plates are formed so that they will securely
hold the brush-board or stock to be operated upon while such brush-board or stock
is being drilled.
According to a further part of our invention we employ a frame provided with a
templet as above described. In one end of each of the arms of such frame are
formed holes which are passed upon a bar or rod or bars or rods formed upon or
secured to a plate or bar capable of being slidden longitudinally between guides
secured to the framework of the machine. The frame above mentioned is capable of
being turned upon the bar or rod or bars or rods before mentioned and may also be
slidden longitudinally upon the said bar or rod or bars or rods.
21
This arrangement of our invention is particularly applicable to brush-boards or
stocks in which the rows across the width have a slight amount of "angle" or
divergence and in which the rows lengthwise of the brush-boards or stocks are
parallel.
A machine constructed according to this part of our invention is illustrated by
Figs. 18 and 19 of the accompanying drawings Fig. 18 being an.elevation and Fig. 19
a plan of that which is shown in Fig. 18. Figs. 184 and 18B show the form of
brush-board or stock in the drilling of the holes in which the machine shewn in
Figs. 18 and 19 is required. As certain parts of the machine illustrated by Figs. 18
and 19 are similar in construction and operation to similar parts employed in the
machines previously referred to, we shall affix to such parts the same letters of
reference as we have applied to the corresponding parts above described.
Secured to the slide-bar or plate d is a rod 16. The arms a¹ are provided with
sockets 17 which are capable of being turned and slidden longitudinally upon the.
rod 16.
Secured to the arins a' is the templet a which in the machine now being described
is straight.
The brush-board or stock to be operated upon is fastened to brackets 18 secured to
or formed upon the arms a¹. As the movement of the templet a in the direction of
the axis of the rod 16 and the movement in the same direction of the brush-board or
stock being operated upon are equal the holes in each horizontal row of holes drilled
in the brush-board or stock will be the same distance apart as the corresponding
holes A in the templet a but the horizontal rows of holes drilled in the brush-board or
stock may be caused to be nearer together or farther apart according as the brush-
board or stock is placed farther from or nearer to the axis of the rod 16. The turning
of the arms a¹ upon the rod 16 will cause the rows of holes across the width of the
brush-board or stock to have a slight amount of "angle" or divergence. We bave
for convenience of illustration shown the arms a¹ and templet a as broken. The
templet a will require to be of sufficient length and breadth to contain as many
holes as are to be drilled or formed in the brush-board or stock to be operated upon.
The arms a will require to be of such length that the templet a and the brush-board
or stock may be placed at such a distance from the axis of the rod 16 that the holes
forming the vertical rows of holes drilled or formed in the brush-board or stock will
have only a small amount of "angle" or divergence in a direction at right angles
to the length of the brush-board or stock.
23
By means of our invention we are enabled to employ one templet in the
drilling of brush-boards or stocks of various sizes and in the drilling of holes of
various sizes.
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 a machine for drilling the holes in brush-boards or stocks the drill and
head-stock placed between the templet and the brush-board or stock to be drilled.
2. In a machine for drilling the holes in brush-boards or stocks a templet placed
separately from the brush-board or stock required to be drilled and ensuring the
required position and inclination of the holes in the brush-board or stock substantially
as hereinbefore described.

page_text: 3. In a machine for drilling the holes in brush-boards or stocks apparatus mounted
on the arms which carry the templet and enabling the brush-board or stock being
operated upon to be turned so that the holes may be caused to be drilled in the
desired positions substantially as hereinbefore described in reference to and indicated
in and by Figs. 4 and 5 of the accompanying drawings.
4. In a machine for drilling the holes in brush-boards or stocks apparatus mounted
on the arms which carry the templet and enabling the brush-board or stock being
operated upon to be turned so that the holes may be caused to be drilled in the desired
positions substantially as hereinbefore described in reference to and indicated in and
by Figs. 8 and 9 of the accompanying drawings.
5. In a machine for drilling the holes in brush-boards or stocks a toothed sector or
wheel such as is shown in and described in reference to Figs. 10 and 11 of the
accompanying drawings and mounted and causing when the arms which carry the
templet are moved the brush-board or stock to be turned so that each hole may be
drilled in the required position.
