Improvements in Machinery for Drilling, Cutting, or Indenting
Stencil or other Plates or Surfaces according to Patterns.
I, MICHAEL BARKER NAIRN, of Dysart House, Dysart, in the County of Fife,
North Britain, Floorcloth and Linoleum Manufacturer, do hereby declare the
nature of this invention to be as follows, that is to say;-
My said invention has for its object the construction of improved partly auto-
matic machinery for drilling, cutting, or indenting plates or surfaces according
to patterns, and capable of operating on plates of comparatively large size to form
stencil plates for use in the manufacture of patterned linoleum floorcloth or orna-
mental material for decorative purposes.
In a machine made according to my invention there is a horizontal bedplate
surfaced or covered with wood or other suitable material down on which is fixed
a plate or sheet of thin metal or other suitable material to be formed into a
stencil plate. At the sides of the bed plate there are horizontal longitudinal
guides on which rest the sides of a bottom saddle piece or frame extending across
over the bedplate; and on this bottom saddle frame there is movable transversely
on guides thereon an upper saddle frame. The two saddle frames are movable by
screw shafts, the bottom one longitudinally and the upper one transversely, the
screw shafts being suitably geared with other parts for effecting the desired move-
ments.
Upon the upper saddle frame there are one or more drills or other tools for
cutting the stencil plates; also mechanism for depressing the tool or tools into
action or raising it or them as required; also an adjustable seat for an operator
and which moves transversely with the saddle frame; and on the lower saddle
frame there are supports for carrying a copy pattern on design paper or other
suitable paper or material. The copy pattern which may comprise one or more
repeats on the same scale as the stencil plate, and extend quite across the stencil
plate, or so as to include one or a number of repeats only when there are more in
the width, is upon a roller which is turned step by step to bring the lines succes-
sively into position. There is also a pointer which indicates on the pattern the
part corresponding to the position of the tool or tools. The roller and pointer
are moved by connections with the bottom and upper saddles; and are also
capable of adjustment by hand. In positions convenient for the operator there are
handwheels, by which and suitable connecting gearing the operator can control the
transverse and longitudinal movements of the saddle frames and other parts; and
there is a hand lever by means of which the operator can raise and lower the tool
or tools as required by the pattern.
The operations are effected in successive transverse lines, the operator depressing
or raising the tools according to the pattern whilst the upper saddle moves from

page_text: side to side; and as each transverse movement is completed the upper saddle
frame is shifted for the next line either by the operator or by simple auto-
matic mechanism.

Improvements in Machinery for Drilling, Cutting, or Indenting
Stencil or other Plates or Surfaces according to Patterns.
I, MICHAEL BARKER NAIRN, of Dysart House, Dysart, in the County of Fife,
North Britain, Floorcloth and Linoleum Manufacturer, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement, that is
to say;
-
My said invention has for its object the construction of improved partly auto-
matic machinery for drilling, cutting, or indenting plates or surfaces according
to patterns, and capable of operating on plates of comparatively large size to form
stencil plates for use in the manufacture of patterned linoleum floorcloth or orna-
mental material for decorative purposes.
In my improved machinery the plate to be formed into a stencil plate is fixed
on a bed plate surfaced with wood, or other suitable material, the drill, or other
cutting or indenting tool or tools driven in any suitable way, and capable of being
raised or lowered by the operator, being mounted on frames, running in guides,
and capable of being moved transversely or longitudinally by screw shafts worked
by the operator, a roller carrying the copy pattern, and a pointer resting on the
pattern, being arranged to work in connection with the frames, and likewise to
be capable of adjustment by hand, the pointer indicating on the pattern the part
corresponding to the position of the drill or other cutting or indenting tool or
tools.
And in order that my said invention and the manner of performing the same
may be properly understood I hereunto append three sheets of explanatory draw-
ings to be hereinafter referred to in describing my improvements.
Figures, 1, 2, and 3, on Sheets, 1, 2, and 3, of the accompanying drawings are
respectively a plan, a side elevation, and an end elevation of a machine made
according to my invention. In these drawings the same reference letters and
numerals are used to mark the same or like parts wherever they are repeated.
In a machine made according to my invention there is a horizontal bedplate, A,
having on it a block, A 1, of wood or other suitable material down on which is
fixed by screw bolts, A2, a plate or sheet, A3, of thin metal or other suitable
material to be formed into a stencil plate. At the sides of the bedplate, A, there
are horizontal longitudinal guides, B, B1, on which rest the sides, B2, B3, of a
bottom saddle piece or frame, B4, extending across over the bedplate; and on this
bottom saddle frame there is movable transversely on guides, B5, formed thereon
an upper saddle frame, C. The bottom saddle frame, B4, is movable longitu-
dinally by screw shafts, D), D 1, fitted in the guide frames, B, B1, and working in
suitably screwed parts of the sides, B2, B3. Similarly the upper saddle frame, C,
is movable transversely by a screw shaft, E, fitted in the bottom saddle frame, B4,
and working in a suitably screwed part of the upper saddle frame. The screw
shafts, D, II, are operated by means of handled vertical shafts, F, F 1, worked by
the operator. These vertical shafts, F, F 1, transmit motion, by bevil gear, F2, F 3,

page_text: to longitudinal shafts, F4, F5, which through spur gear, F6, F7, give rotation to
the screw shafts, D, D 1. A cross shaft, FS, is provided gearing by bevil wheels, F 9,
with the longitudinal shafts, F4, F5, so that the screw shafts, D, D1, may be
operated from either side of the machine. The screw shaft, E, which moves the
upper saddle frame, C, is operated by a handled vertical shaft, G, worked by the
operator, this shaft transmitting motion, by bevil gear, G1, to a transverse
shaft, G2, which through spur gear, G3, gives rotation to the screw shaft, E.
Upon the upper saddle frame, C, there is in the example shown arranged a
drill, H, or it might be two or more drills or another tool or tools for cutting or
indenting the stencil plates. The drill, H, is driven by belt gearing, H 1, the
pulley shaft, H2, transmitting motion through bevil wheels, H3, to a transverse
shaft, H 4, which by similar means turns the drill spindle, H 5. Instead of the
drill being driven by belt gearing, it may be driven by an electric motor acting
directly on the drill spindle, or through gearing to give a suitable speed. The
drill, H, is depressed into action or raised by links, J, connected to the drill
spindle, H 5, and to a lever, J 1, fixed on a transverse shaft, J 2, turned by a
lever, J3, fixed thereon and to a vertical rack, J 4, receiving movement from a
pinion, J 5, fixed on an upper transverse shaft, J 6, turned by the operator by means
of a hand lever, J 7, fitted to a disk, J 8, which is keyed on the shaft, J 6. A balance
weight K, attached to a drum K1, on the shaft, J 6, is provided to return the
drill, H, to a raised position. When operating on plates or surfaces other than
stencil plates the depth of cut or indentation may be determined by applying an
adjustable stop to limit the downward movement of the tool (H).
An adjustable seat, L, for an operator is also provided which is mounted on a
bracket, L 1, on the upper saddle frame, C. On the lower saddle frame, B4, thero
are supports or brackets, M, M1, for carrying a copy pattern on design
paper or other suitable paper or material. The copy pattern (not shown) which
may comprise one or more repeats on the same scale as that of the pattern to be
reproduced on the stencil plate, A3, and extend quite across the stencil plate, or
so as to include one or a number of repeats only when there are more in the
width, is upon a roller, N, fitted to turn in bearings, M2, M3, on the
brackets, M, M 1, and which is turned step by step to bring the lines successively
into postion. There is also a pointer, N 1, fixed to a standard, N 2, on the upper
saddle frame, C, which indicates on the pattern the part corresponding to the
position of the drill or other tool or tools. The roller, N, receives its rotative
movement from one of the vertical shafts, F, a worm, P, on this shaft acting on
a worm wheel, P1, on a transverse shaft, P2, on which there is also fixed a spur
wheel, P3, gearing with an intermediate spur-wheel, P4, fitted in an adjustable
bracket, P5, and which gears with a spur-wheel, P6, fixed on the roller shaft, N 3.
The roller and pointer are also capable of adjustment by hand As has been
indicated there are in positions convenient for the operator handwheels, Q, Q1, Q 2,
by which the transverse and longitudinal movements of the saddle frames and
other parts can be controlled, and the hand lever, J 7, also enables the operator to
raise and lower the drill, H, or other tool or tools as required by the pattern.
The operations are effected in successive transverse lines, the operator depressing
or raising the tool according to the pattern whilst the upper saddle, C, moves from
side to side; and as each transverse movement is completed the upper saddle
frame is shifted for the next line either by the operator or by any simple auto-
matic mechanism.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
The combination and arrangement of parts constituting my improved
machinery for drilling, cutting, or indenting stencil or other plates or surfaces

page_text: according to patterns, all substantially as herein before described and shown in
the accompanying drawings.
