Improvements in Wood Sawing Machinery.
We, Jonx PICKLES and GEORGE PICKLES of the Firm of John Pickles
and Son, of Royd Iron Works, Hebden Bridge, Yorkshire, Machine Makers, do
hereby declare the nature of this invention to be as follows:-
This invention refers to wood sawing machines and consists of combining with
the moveable or sliding table, a horizontal feed roller or rollers driven by bevil or
suitable gearing from a convenient part of the machine and mounted or carried
in a bracket or pedestal secured to the top of the sliding table and adapted to allow
for sufficient lead being given to the feed roller, said horizontal feed being moveable
with the table and capable of advancement up to the periphery of the circular saw
by which means also the feed is adjusted to various diameters of saws which may be
employed. The horizontal feed with its bearing or pedestal are removeable from
the table and interchangeable with a vertical feed which can be mounted on the
same shaft or driven by the same gearing, the bracket supporting said shaft being
moveable on a stud or pivot so that the feed roller or rollers may be placed at any
angle and secured by bolts or studs passing through quadrant slots in the aforesaid
bracket or bearing. The vertical feed roller is moveable with the sliding table up
to the periphery of the circular saw as is the case with the horizontal feed roller,
and is also adjustable to any required angle either in conjunction with a bevilling
fence or not, the latter being adjustable also to any required angle by means of
worm or screw and toothed quadrant operated by hand, the said fence also sliding
with the table so that the feed roller or rollers and fence always maintain the same
relative positions to the circular saw or saws whatever may be their diameter.
Secured to the fence is a bracket or plate projecting from the fence at right
angles and level with the sliding table when said fence is in a vertical position, but
when inclined at any angle the said bracket or plate forms the support for the board
or plank being sawn or cut to an angle, and prevents same being thrust down and
jammed between the saw and the fence.
The vertical or angular feed roller kept in contact with the board or plank by
means of a weight suspended from the end of a chain, or by like devices.
The machine constructed as above is simplified, the parts are not in the way of
the attendant as heretofore, and a change can easily and quickly be made from a
horizontal to a vertical feed roller and the latter and the fence inclined to suit various
requirements.

COMPLETE SPECIFICATION.
Improvements in Wood Sawing Machinery.
We, JOHN PICKLES and GEORGE PICKLES, of the Firm of John Pickles
and Son, of Royd Iron Works, Hebden Bridge, Yorkshire, Machine Makers, 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:-
This invention refers to wood sawing machines, and consists of combining with
the moveable or sliding table, a horizontal feed roller or rollers driven by bevil or
suitable gearing from a convenient part of the machine and mounted or carried in a

page_text: bracket or pedestal secured to the top of the sliding table and adapted to allow for
sufficient lead being given to the feed roller, said horizontal feed being moveable
with the table and capable of advancement up to the periphery of the circular saw,
by which means also the feed is adjusted to various diameters of saws which may
be employed.
The horizontal feed with its bearing or pedestal are removeable from the table
and interchangeable with a vertical feed which can be mounted on the same shaft
or driven by the same gearing, the bracket supporting said shaft being moveable
on a stud or pivot so that the feed roller or rollers may be placed at any angle and
secured by bolts or studs passing through quadrant slots in the aforesaid bracket
or bearing. The vertical feed roller is moveable with the sliding table up to the
periphery of the circular saw as is the case with the horizontal feed roller, and is
also adjustable to any required angle either in conjunction with a bevilling fence or
not, the latter being adjustable also to any required angle by means of worm or screw
and toothed quadrant operated by hand, the said fence also sliding with the table
so that the feed roller or rollers and fence always maintain the same relative
positions to the circular saw or saws whatever may be their diameter.
Secured to the fence is a bracket or plate projecting from the fence at right
angles and level with the sliding table when said fence is in a vertical position, but
when inclined at any angle the said bracket or plate forms the support for the board
or plank being saw or cut to an angle, and prevents same being thrust down and
jammed between the saw and the fence.
The vertical or angular feed roller is kept in contact with the board or plank
by means of a weight suspended from the end of a chain, or by like devices.
In order that our invention may be more fully explained reference is herein
made to the accompanying drawings illustrative thereof, wherein :-
Fig. 1 is longitudinal section of a wood sawing machine constructed and arranged.
according to our invention.
Fig. 2 is transverse section of same, and
Fig. 3 is a similar section shewing the feed roller and fence arranged for bevel
or angular cutting.
Fig. 4 is a detail of the fence,
Fig. 5 is side elevation, and Fig. 6 end elevation of the horizontal feed roller for
horizontal cutting.
Referring to the drawings A represents the machine frame, B the table adapted
to be slided backwards and forwards in suitable ways on said frame by means of
hand wheel C and screw D working through a nut in the frame, and E is the
circular saw mounted on the shaft and driven in the ordinary and well known
manner. In Figs. 1, 2, and 3, we have shewn the vertical feed rollers G applied to
the machine these being interchangeable with the horizontal feed roller shewn at
Figs. 5 and 6, and hereafter referred to.
The vertical feed rollers G are mounted and secured on the vertical shaft HL
supported in a bearing or footstep.I formed in the bracket or casting J which is'
secured. by bolts a to a supporting plate K, adapted to slide in paths or ways to
or from the saw in order to adjust the feed rollers to different widths of timber to
be operated upon, this being effected by means of hand wheel c and screw d working
through a nute secured to the plate K. The vertical spindle or shaft H has
mounted thereon a bevil wheel L provided with a hollow tube or shaft which
extends through the bearing or footstep 1 and is secured by a nut f. Gearing
with the bevil wheel L is a bevil wheel M which is supported by the bracket.J
as shewn in Fig. 1.
A recess is formed in the end of the solid boss or neck of the wheel M into
which enters a corresponding piece on the end of the shaft N forming a nut or key
for driving the said wheel M.
The shaft N is driven from the shaft P through the medium of gearing. O, and
at Q the said shaft is supported by a ball bearing in order to allow for its angular
movement with the adjustment of the feed rollers.

page_text: is the fence carrying anti-friction pulleys g (see Fig. 2), between which and
the feed rollers the timber to be sawn is firmly held and guided or fed to the saw.
The said fence is hinged at h and is provided with a toothed quadrant i into which
gears the worm k mounted on the spindle carried by the plate or bracket to
5 which the fence is hinged. The said worm k is actuated as and when desired for
tilting the fence R by means of a key or a small hand wheel. A bolt is passed
through the plate or bracket and is screwed into a nut in the casting / which
is carried by the shaft m, which said shaft m is moved end wise in either direction
by the screw m' for sliding the fence towards or from the saw to adjust it to the
U timber to be sawn.
The parts described with reference to Figs. 1 and 2 shew the arrangement of
apparatus for vertical cutting secured to and carried by the table B, the fence R
and feed rollers G can therefore be adjusted or brought close up to the periphery
of the saw whatever may be its diameter, this being accomplished without
5 disturbing the relative positions of the said parts. By this means the timber is
steadied and fed to the saw right up to the end of its movement.
In order that the same parts may be used for angular or bevil cutting, the bolts a
are passed through quadrant slots a' in the bracket J and the latter is adapted to
be turned upon the stud or fulcrum p formed on or secured to the plate K, therefore
by loosening the nuts on the bolts a the bearing or bracket J and parts supported
thereby may be placed at any angle, up to say, 45° as will be understood by reference
to Fig. 3, and the fence R is likewise placed at a corresponding angle by meaus of
the worm and toothed quadrant i, thus holding and feeding the timber at the
angle at which the bevil is required to be cut.
For bevel cutting we may attach to the fence a shelf or support to carry the
timber as shewn at Fig. 4.
The feed roller or rollers are kept in contact with the timber by means of the
weight S suspended at the end of a chain attached to the bracket J or other suitable
part of the vertical feed. The vertical or angular feed roller or rollers can,
whenever required, be removed from the machine and the horizontal feed rollers
attached thereto, the vertical spindle H being supported in the bearing I and
driven by the bevil wheel M as previously described with reference to the vertical
feed rollers. A second bevil wheel T is however mounted on the vertical spindie or
shaft H (see Figs. 5 and 6) which gears with the bevil wheel U fast on the shaft of
the horizontal feed roller G¹ in order to give the requisite motion thereto to feed
the timber forward to the saw. A weighted lever V is employed to keep the said
roller G in contact with the timber.
The said horizontal feed roller is moveable with the table B up to the periphery
of the saw and is also moveable in a direction at right angles to the saw by means
of the screw d shewn in Figs. 1 and 2. The machine described is also provided
with the ordinary rope drag feed which can be brought into use whenever the
power of the feed is insufficient to traverse the timber to the saw.
The machine constructed as above is simplified, the parts are not in the way of
the attendant as heretofore, and a change can easily and quickly be made from a
horizontal to a vertical feed roller or vice versu and the latter and the fence inclined
to suit various requirements.
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 :-
Firstly. In wood-sawing machines, the combination with a moveable table of the
arts comprising the vertical or angular feed motion interchangeable with a
orizontal feed motion and adjustable fence adapted to be inclined to different
ngles and moveable with the table to or from the circular saw all arranged and
perating in the manner substantially as herein shewn and described.
Secondly. In wood-sawing machines, the combination with a moveable table
of parts forming the horizontal feed motion adjustable to or from the circular

page_text: saw and moveable with the table all arranged in the manner and for purposes set
forth.
