Improved Wcod-working Machine, the same being also Applicable for
Use in the Cutting and Shaping of Metal.
I, THOMAS SHURMER, of 306, Manchester Road, Bolton, in the County of Lan-
caster, Joiner and Builder, do hereby declare the nature of this invention
to be as follows, that is to say;-
It relates to an improved wood-working machine the same being also applicable
for use in the cutting and shaping of metals, and my said invention consists in
constructing and arranging the parts forming said machine in such a manner
that varied cutting operations either on wood or metal may be performed effi-
ciently by it.
In accordance with my invention I arrange a rotary cutter so that its operating
spindle may slide vertically upon its bearings to advance towards or recede from
its work, certain parts of its said bearings being made to slide upon the frame-
work and to be moved by either a hand or power operated screw device or said
screw may be only used as coupling means for enabling lever mechanism to
transmit motion to the spindle, thus this latter when desired to be fed quickly
to its work may be moved by said lever mechanism while when it has to be fed
thereto by the screw mechanism then appropriate locking devices are employed
for firmly screwing the lever operated parts.
Beneath the rotary cutter mounted above as described I mount a table which
I arrange to rotate upon the framework when desired or which when not required
to move may be secured rigidly by set screws or otherwise to said framework.
When this circular table has to rotate its motion may be effected manually by
the operative or appropriate screw and wheel or toothed gearing mechanism may
be employed with coupling devices for obtaining said rotary motion from any
motor part of the machine.
Upon the table mounted as above described I place another or additional table
which I arrange to slide, by having appropriate guiding surfaces, over the sur-
face of the table beneath. The sliding movements of this table may also be per-
formed manually or by a shaft extending centrally from and through the lower
table, worm and wheel mechanism or rack and pinion devices may be employed
to transmit motion thereto thus varied movements may be transmitted to this
additional table by which means articles that are secured to it may be subjected
in many ways to the actions of the rotary cutter.
It will be seen that by having the mehanical devices which transmit the sepa-
rate movements to the tables, so arranged that considerable variation, from a
comparatively slow to a very high speed, may be made therein as also means for
regulating in like manner the speed of the cutter, either articles of wood or those
of metal may be acted upon.
The cutter for use in connection with the spindle arranged as above described,
when articles of wood have to be acted upon, I so construct that as it diminishes
in size by wear, I can adjust it to perform its cutting operations through the

page_text: same path of motion or space that it traversed prior to being thus worn, suitable
slots with appropriate setscrews being employed for this purpose.
By having a cutter of an appropriate crescent shape in cross section and by
having slots formed in it or in its bearings or in both of them it will be seen
that the cutter may be adjusted to travel through a path of considerable magni-
tude and that it may be further adjusted to travel in a comparatively limited
path.
To enable the additional table to travel or move through yet another path in
addition to those above referred to, I pivotally mount it upon the sliding part
which operates upon the table beneath and I arrange said additional table when
thus mounted to be operated by worm and wheel or other devices as may be found
advantageous.

Improved Wood-working Machine, the same being also Applicable for
Use in the Cutting and Shaping of Metal.
I, THOMAS SHURMER, of 306, Manchester Road, Bolton, in the County of Lan-
caster, Joiner and Builder, 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:-
It relates to an improved wood-working machine the same being also applicable
for use in the cutting and shaping of metals, and my said invention consists in
constructing and arranging the parts forming said machine in such a manner
that varied cutting operations either on wood or metal may be performed effi-
ciently by it.
In the accompanying drawings, which are illustrative of my said invention:-

Fig. 2 is a front view of said machine.
Fig. 3 is a plan of the tables and parts of said machine.
Fig. 4 is a part sectional elevation of said tables.
Figs. 5, 6 and 7 are front and side elevation and sectional plan respectively of

the table shown by Fig. 10.
Figs. 15, 16 and 17 are elevation, plan and sectional view illustrating means
whereby the movements of the table are automatically performed.
Like letters and figures of reference indicate like parts throughout the several
views.
A indicates the framework of the machine.
In accordance with my invention I arrange a cutter so that its operating
spindle may slide vertically in bearings c c to advance towards or recede from
its work as hereinafter described, its rotary motion being derived from the prime

page_text: motor shaft & through the pulleys e e¹ ell and the belt f, the spindle 6 carrying
a feather or key-way b¹ so that although free to slide through the pulley e¹¹ it
may be rotated by it.
The spindle passes through the coupling piece 9 with which the screw h
meshes, in order that said screw may act as a connecting rod to couple the
lever to the spindle b. The lever is pivotted at ¹ to the arm m hinged at m¹
to the holding arm m so that the operative may move the cutter a vertically by
means of the handle m¹ the counterbalancing weight assisting him in his
operations, while the holding arm m¹ allows the guide pulleys e¹ to be carried by
their supporting arms ell (pivotted at 3) to any position that the tension of the
driving belt may necessitate, a screw fi securing same in position.
When the cutter a has to operate only to a given depth its descent may be
arrested by the adjustable arrester n secured to the framework A by the hand
screw n¹ (see also Figs. 8 and 9) the screw being to enable the adjustment of
the piece g relatively with the pivotal centres ¹ and k¹, while when the cutter a
has to operate in a fixed plane then the screw his locked in position by the hand
screw in which case the lever ceases to be used, and if desired, the part g
may be raised or lowered by turning the hand wheel fixed to the upper end
of the screw h.
Beneath the cutter a I mount a table o which I arrange so that it may be re-
volved upon the framework A when desired or which when not required to move
may be secured rigidly thereto by the screw o¹. When this table o has to rotate
its motion may be effected manually by the operative in which case its simple
bearings shown by Figs. 1 and 2 are employed, or motion may be transmitted to
it from the shaft d by the gearing wheels 4, 5, 6 and 7, sleeve 25 and shaft 8
as shown by Fig. 15.
Upon the table o I mount another table which I arrange by its dovetailed
strip p to slide over the table o by taking into a groove made in the table o to
receive same as well as to rotate upon said strip p about the pivotal pon 2. The
sliding movements of this table as well as its rotary motion may also be per-
formed manually by the operative in which case their simple mountings shown
by Figs. 1, 2, 3 and 4 may be made use of, or by arranging the shaft 9 (see
Figs. 15, 16 and 17) to extend centrally through the table o and carry a gear
wheel 10 meshing with a wheel 11 secured to a screwed shaft 12 pivotally mounted
to said table o, rotary motion may be transmitted from the shaft 8 through the
gears 13 and 14 to said shaft 12 from which rotary motion when desired may be
transmitted to the table p by the gears 15 and 16, however as the shaft 12 is a
screwed shaft (and the wheel 15 moves over it on a key way or feather when the
half nut 17 mounted upon the projection 18 secured to the table p is put into gear
with it, said screw 12 will transmit the sliding movement to said table ?) as
desired. Clutch coupling devices or ordinary set screws may be employed for
securing the wheels 6 and 16 to their respective motors or releasing same there-
from when one or the other is or is not desired to be employed.
From the foregoing it will be seen that when a piece of wood is secured to the
table p (by the clamping device 19 or by any other means) it may be subjected
to the actions of the cutter a and guided or moved in many and varied paths
relatively therewith to be treated as may be desired.
The cutter a is preferably made when for plain work of curved form shown
by the sectional drawing Fig. 7 and its attachment to the spindle 6 is preferably
by the slotted part 6 so that adjustment to compensate for wear through usage
may be effected as well as adjustment to enable the cutter a to be taken by its
said spindle through a greater path of motion.
For producing moulds or circular parts as well as straight pieces the form of
the cutter a is made of a corresponding shape as is well understood, while for
passing long articles to be treated by said cutter a over the top of the table >>
I may use a guide piece or fence 20 as shown by Figs. 13 and 14.
If desired a cutter 21 arranged to rotate in the vertical plane as shown in

page_text: broken lines Fig. 1 may be made use of when found desirable since its rotary
motion may be readily derived from the shaft d through the pulleys 22 and 23
and the shaft 24.
It will be seen that by having the mechanical devices which transmit the
separate movements to the tables so arranged that considerable variation, from
a comparatively slow to a very high speed, may be made therein as also means for
regulating in like manner the speed of the cutter, either articles of wood or those
of metal may be acted upon.
It will readily be understood that I may mount the tables o and p to operate
in connection with the cutters and spindles of other forms of machines that the
one herein specified, and in these cases they will also perform their functions in
the manner above described.
