Improvements in Machines for Carving and Engraving Wood and
other Materials.
We, THOMAS RYLAND, of Hope Cottage, Carlton Grove, Brixton, in the
County of Surrey, Mechanic, and EARLE BIRD, of 4 Carlton Grove aforesaid,
Builder, do hereby declare the nature of this invention to be as follows:-
The invention relates to a novel construction, combination and arrangement of
parts whereby a very simple, effective and easily driven carving or engraving
machine is produced.
In carrying the invention into effect we employ, as heretofore, a stationary table,
on which the pattern and the block or blocks to be carved or engraved are
fixed, in combination with a movable tracing pointer and one or more rotating
carving or engraving tools.
We mount the tracing pointer and the carving or engraving tool or tools on the
front member of a conveniently rectangular frame extending over the machine
bed or table. Near the rear end, this frame is provided with suitable guides
mounted on a bar parallel with the front member of the tool frame and preferably
of inverted V form, so as to enable said tool frame to be moved in a line parallel
with front of machine. This bar is mounted at its ends in bearings with capability
of rocking freely therein, so as to enable the said tool frame to be oscillated and
thereby cause the front member thereof to rise and fall, as may be required, from
and to the work and pattern, whereby the tracing pointer and cutter or cutters are
enabled to work as shallow or as deep as may be required.
The bearings for the oscillating cross bar carrying the tool frame are carried
at the ends of a cross bar or frame mounted in or on suitable guides fixed at right
angles to the front of the machine and also preferably of inverted V form, so as
to permit the said cross bar or frame with the tool frame to be moved in a direction
to and from the front and back of the machine bed or table.
The back member of the tool frame is in the form of a shaft, on which are
freely mounted one or more pairs of guide pulleys for the cutter driving band or
bands. In slots or guides at the lower parts of the machine standards, is mounted
a counter-shaft, on which are loosely mounted one or more pairs of guide pulleys,
and said countershaft is weighted or acted upon by springs to give it a normally
downward tendency. The countershaft may be otherwise mounted to produce the
same effect.
The machine frame is fitted with a driving shaft carrying a long drum, and said
driving shaft may be driven by a treadle or by power acting upon a driving pulley
fixed thereon.
A driving band for each cutter or carving or engraving tool is passed partly
around the drum, then partly around the several pairs of guide pulleys above
described and partly around the driving pulley of the carving or engraving tool.
The guide pulleys are capable of sliding along their carrying shafts and the cutter
driving band or bands is or are capable of travelling along the long drum. By
the above construction of parts the tracing point and the carving or engraving
cutter or cutters are capable of being moved in any direction over the pattern
and work without in any way affecting the driving of the cutter or cutters.
We also, in order to enable undercutting to be executed, so mount the cutter or
cutters as to enable it or them to be tilted either forward or backward, or to either
side, or to positions partaking of two of such directions, as may be required.

page_text: For this purpose each cutter may be conveniently mounted in a frame capable
of swivelling around a screwed stud or axis carried by the front member of the
tool frame and of being fixed by means of nuts, and we mount said front member
of the tool frame in bearings in the side members thereof, so as to be capable of
oscillating at right angles to the oscillating motion of the cutter frames.

COMPLETE SPECIFICATION.
Improvements in Machines for Carving and Engraving Wood and
other Materials.
We, THOMAS RYLAND, of Hope Cottage, Carlton Grove, Brixton, Surrey,
Mechanic, and EARLE BIRD of 4 Carlton Grove aforesaid, Builder, do hereby
declare the nature of this invention, and in what mauner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:—
The invention relates to a novel construction, combination and arrangement of
parts whereby a very simple, effective and easily driven carving or engraving
machine is produced.
In carrying the invention into effect we employ, as heretofore, a stationary
table, on which the pattern and the block or blocks to be carved or engraved are
fixed, in combination with a movable tracing pointer and one or more rotating
carving or engraving tools.
Our invention is illustrated in the accompanying drawings, in which :-
Fig. 1 is an end view, Fig. 2 a front view, Fig. 3 a back view and Fig. 4 a plan,
of the improved machine.
Fig. 5 is a front view and Fig. 6 a sectional end view of parts for carrying and
guiding the tracer and cutter frame in a direction parallel with the front of the
machine.
Fig. 7 is a side view and Fig. 8 a sectional front view of parts for carrying
and guiding the parts shown at Figs. 5 and 6 in a direction at right angles to the
front, and
Fig. 9 is a cross section showing one of the carving or engraving tools and the
parts for carrying and rotating the same.
a a are the end frames and 6 the top or bed of the machine; c is the driving or
crank spindle, which can be rotated by a treadle d and connecting rods d' or by
means of a strap acting on a pulley (not shown) fixed on such spindle. e is a
fly wheel.
g on
We mount the tracing pointer and the rotating carving or engraving tools
the front member of a frame extending over the machine bed b. Near the
rear end this frame h is provided with guides, preferably rollers h², mounted on a
bar i parallel with front of machine, so as to enable the tool frame to be moved
in a direction parallel with front of machine. This bar i is mounted at its ends in
bearings carried at the ends of a cross bar or frame j provided with wheels j²
mounted on guides b' fixed in the machine bed at right angles to the front of the
machine so as to permit the said cross bar or frame j to be moved towards and
from the front and back of the machine bed. The guides are preferably, as
shown, of form and the wheels are made to fit the same; the bar i, although
shown of circular section, may also be of A form, but if desired other descriptions
of guides may be employed for these parts.

page_text: By these means the tool frame is capable of being moved so as to bring the
tracer fover every part of the pattern, whilst the tool frame h can be oscillated on
the bar i, thereby enabling the front member thereof to be raised and lowered
as may be required from and to the work and pattern, whereby the tracing
pointer and cutter or cutters g are enabled to work as shallow or as deep as may
be required.
The back member h³ of the tool frame is in the form of a shaft, on which are
freely mounted one or more pairs of guide pulleys k for the cutter driving band
or bands l.
In guide slots m³ formed in adjustable brackets m at the lower parts of the
standards a, is mounted a counter-shaft n, on which are loosely mounted one or
more pairs of guide pulleys o, and said counter-shaft n is weighted or acted upon by
springs n' to give it a normally downward tendency, or it may be otherwise mounted
to produce a like effect.
The spindle c is fitted with a long drum c¹ ; a driving band 1 for each carving or
engraving tool 9 is passed partly around the drum c', theu partly around the guide
pulleys k, o, and partly around the driving pulley y' of the carving or engraving
tool. The guide pulleys ko are capable of sliding freely along their carrying
shafts h³n, and the cutter driving band or bands lis or are capable of travelling
along the drum c¹.
By the above construction and arrangement of parts, the tracing point fand the
carving or engraving cutter or cutters 9 are capable of being moved in any direction
over the pattern and work without in any way affecting the driving of the cutter
or cutters g.
Each cutter g is removably fixed in a chuck spindle g² on which the pulley g' is
fixed, and such spindle g2 is mounted in bearings g³ carried by a plate 9' which is
adjustably fixed to the front member h' of the cutter frame by a screwed stud g³
and fly nut 96.
By these means the cutter or cutters may be swivelled around the stud 9 and
fixed either in a vertical direction or in inclined directions with the cutting end.
pointing to either side as may be required for undercutting and if desired the cutter
carriers may be coupled together so that they shall move in unison around their
studs g.
The front member h¹ of the cutter frame is also provided with trunnions *
mounted in bearings in the front ends of the side members of the frame / to enable
the cutters to be placed in a vertical position or to be tilted either forward or
backward for undercutting, set screws h³ being employed to fix the said cutter
carriers in any required position.
The cutter frame h is balanced on the rod i by the tension of the cutter driving
bands but is otherwise entirely disconnected from the fixed parts of the machine;
it is therefore, and consequent upon the arrangements before described, capable of
being freely moved about in any direction and may be entirely removed from the
other parts of the machine as may be required.
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:-
1. In carving or engraving machines, the combination of a driving spindle, a
long drum on said spindle, a counter-shaft having a normally downward tendency,
band pulleys mounted freely on said counter-shaft, a cutter frame mounted on a
guide parallel with machine, front and carried by a frame mounted on guides at
right angles to machine front, band guiding pulleys mounted loosely on a shaft
forming part of cutter frame, a tracing pointer and rotary cutter or cutters mounted
on front of cutter frame, and cutter driving bands passing partly around the cutter
pulleys, guide pulleys on cutter frame, guide pulleys on counter-shaft and partly
around the long drum, substantially as herein shown and described.
2. In carving or engraving machines, the combination with suitable driving

page_text: means, of a cutter frame mounted on guides carried by the bed of the machine and
capable of freely moving in any direction over the said bed, and a fixed tracer
and rotary cutter or cutters carried by the cutter frame, substantially as herein
shown and described.
3. The peculiar construction, combination and arrangement of parts, substantially
as herein shown and described.
