Improvements in Wood Sawing Machinery.
I, 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:-
The primary part of my invention refers to means by which the feed roller or
rollers may be moved out of the perpendicular to any angular position corre-
sponding or conforming to the position of the canting or bevilling fence and always
remain in the same relative position thereto whatever the diameter of the saw
employed may be.
In carrying out my invention I employ a hollow tube or sleeve which is passed
over the horizontal shaft by which motion is conveyed to the feed rollers, and
forms a bearing therefor. To the front end of said tube is coupled by a suitable
form of socket or like joint, a radial arm, or pedestal forming a radial arm, which
is recessed or provided with an opening to receive the bevil wheel on the end of
the driving shaft and the corresponding bevil wheel on the feed roller shaft, which
latter is journalled in and earried by the aforesaid radial arm.
The radial arm is secured to the end of the hollow sleeve or tube by a bolt
passed through a quadrant slot which admits of said arm being adjusted to any
angle to suit the position of the canting fence; a hand wheel and screw being
employed in conjunction with the radial arm for moving the latter when adjustment
is required, and a weight suspended from the end of a chain connected to the radial
arm serving to keep the feed roller or rollers in contact with the timber being
sawn. The whole of said parts are situated immediately under the table top, out
of sight and out of the way of the workmen, and are adapted to move or slide
with the table to any extent necessary to bring the feed rollers and fence up to the
periphery of the saw, whatever its diameter inay be, the same relative positions of
the parts, after adjustment, being maintained throughout.
On the front or other convenient portion of the radial arm I mount a small anti-
friction roller or pulley adapted to engage with and ride over a semicircular rail
when the position of the feed rollers is adjusted, said rail forming a support to the
radial arm and relieving the driving mechanism of the delivery end of the machine,
of the weight and strain which would otherwise be put thereon, whereby the parts
work more smoothly and truly and will last longer.
The gearing for actuating the feed rollers is driven by cone pulleys or drums,
but instead of the driven cone being journalled in fixed bearings, I mount it on a
stud secured to the end of a lever arm and couple said stud by a connecting rod to
the stud or shaft on which the driving cone is mounted this arrangement allowing
the aforesaid gearing to move end wise with the table without affecting the position
or distance of the centre of the driven cone pulley with respect to centre of the
driving cone pulley.
The radial arm may be arranged and constructed to allow of the feed rollers
being removed from the machine or other feed rollers, either vertical or horizontal,
substituted therefor.
When not required, the above parts may remain inoperative, and, being clear of
the table, will permit of the machine being used for ordinary sawing purposes.

page_text: J. 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:-
The primary part of my invertion refers to means by which the feed roller or
rollers may, by means of a radial arın situated underneath the saw table, be moved
towards or away from the canting fence to accomodate varying widths of timber
fed to the machine the means for actuating said feed rollers and for bevilling or
-setting them at any desired angle corresponding to or conforming with the position
of the canting fence being carried by said radial arm.
In carrying out my invention I'employ a hollow tube or sleeve which is centred
or pivoted on a vertical shaft from which the shaft for imparting motion to the
feed rollers is driven the last named shaft passing through and being supported in
and by the said hollow tube or sleeve. To the front or free end of the hollow
tube or radial arm is coupled or attached by a suitable form of socket or like
joint, a pedestal or bearing in which the feed roller shaft is journalled and which
is recessed internally or provided with an opening or openings to receive the bevil
wheels fixed respectively on the end of the driving shaft carried by the radial arm
and on the feed roller shaft. The said pedestal or bearing is secured to the end
of the hollow sleeve or radial arm by a bolt passed through a segmental slot which
admits of said bearing being adjusted to any angle to suit the position of the canting
fence as at present, a hand wheel and screw being employed in conjunction with
the radial arm for adjusting purposes, and a weight suspended from the end of a
chain connected to the radial arm serving to keep the feed rollers in contact with
the timber being sawn. The whole of said parts are situated immediately under
the saw table, out of sight and out of the way of the workman, and are adapted to
move or slide with the table to any extent necessary to bring the feed rollers and
fence up to the periphery of the saw, whatever its diameter may be, the position
- of the feed rollers being also adjustable radially to suit the width of timber being
sawn, the same relative positions of the parts, after adjustment, being maintained
throughout.
On the front or other convenient portion of the radial arm I mount a small
antifriction roller or pulley adapted to engage with and ride over a rail when the
position of the feed rollers is adjusted, said rail forming a support to the radial
, arm and relieving the driving mechanism at the delivery end of the machine, of
the weight and strain which would otherwise be put thereon whereby the parts
work more smoothly and truly and will last longer.
The gearing for actuating the feed rollers is driven by cone pulleys or drums,
but instead of the driven cone being journalled in fixed bearings 1 mount it on a
stud secured to the end of a lever arm and couple said stud by a connecting rod to
the stud or shaft on which the driving cone is mounted, this arrangement allowing
the atoresaid gearing to move end wise with the table without affecting the position
or distance of the centre of the driven cone pulley with respect to centre of the
driving cone pulley.
In order that ny said invention may be more fully understood reference is
hereinafter had to the annexed drawings, forming a part of this specification, in
which:-
Fig. 1 is side elevation of a circular saw bench having my improvements
incorporated therewith, and
Figs. 2 and 3 are respectively end elevation and plan of same.

page_text: Fig. 4 is enlarged longitudinal section of radial arm and parts C
therewith.
Fig. 5 is plan of same, and
Fig. 6 is enlarged end elevation taken on line a, a, of Fig. 4.
Referring to the drawings A represents the framing of the machine, B the
movable saw table, C the screw and hand wheel for actuating the saw table, D the
circular saw, E the canting fence, and F the feed rollers mounted on shaft F, all
said parts being common to these machines and forming no part of my invention,
which consists of a radial arm G situated underneath the saw table for supporting
and carrying the feed rollers F and the horizontal shaft H by which motion is
communicated to the feed roller shaft. The said radial arm G comprises a hollow
sleeve or tube one end of which is provided with a solid extension G and a
depending foot or bracket G both of which are bored to receive the vertical shaft
or epindle I which is jourualled in the footstep J on the bracket J' attached to or
male integral with the movable saw table B and forms the pivot or centre about
which the arm G is adapted to turn or radiate.
The foot or bracket G rests upon and is supported by the footstep J and on the
spindle I between said bracket and the extension G', are placed or mounted the
bevils K, L, the former gearing with a hevil K' on a short shaft K' journalled in
the bracket J and the latter with a bevil L' fast on the shaft H extending through
and supported in the radial arm G.
A slot or opening G is made in the pivoted end of the radial arm to accomodate
the bevil wheel L as shewn. On the opposite end of the shaft H is secured a
second bevil wheel M gearing with a bevil N mounted on the feel roller shaft F
both said bevils entering recesses or openings formed in the bearing or pedestal G
wherein the shaft F is journalled and which is coupled to the end of the hollow
tube or sleeve G by a socket or like joint G and secured thereto by a bolt G
passed through a segmental or quadrant slot G7 (shewn at Fig. 6) which admits of
the said bearing or pedestal being turned about the centre H to any extent within
the limits of the slot to bevil or adjust the feed rollers to any angle to suit the
position or angle of the canting fence E, whilst the adjustment of the arin G
radially moves the feed rollers bodily nearer to or further from the canting fence
to suit the various widths of timber fed to the machine.
The bearing G is preferably made in two portions or halves bolted together, so
that access can be had to the interior thereof whenever desired.
In the end of the bearing or pedestal G is secured a stud O on which is mounted
a pulley or friction bowl P resting on and adapted to ride over the rail P when
the arm G is radiated towards or away from the canting fence E said pulley
serving to support the free end of the radial arm and relieving the driving end of
the weight and strain which would otherwise be put thereon, whereby the parts
work more smoothly and truly, and will last longer. The screw and hand wheel Q
for adjusting the feed rollers, and the weight R suspended from the end of
chain R' passing over pulley R' and secured to the end of stud O, for keeping
the feed rollers in contact with the timber being sawn are employed as heretofore
but beyond acting in conjunction with the radial arm G, form no part of my
invention.
A slot B is formed in the saw table to admit of the full extent of radial
movement of the arm G, and also to allow for the full angular adjustment of the
pedestal or bearing G.
Motion for driving the feed rollers is transmitted by belt or strap from the coné
pulley S at the feeding end of the machine to the, cone pulley T'at the delivery
end of the machine and from thence through the medium of pinion and spur
wheel U, bevils K', K and L to the horizontal, shaft H which, by. means of
bevils M and N, drive the feed roller shaft, the whole of said parts, with the
exception of the driving cone pulley S, being carried by the saw table and movable
therewith.
In order, however, that the distance between the centres of the two cope

page_text: pulleys S and T may remain constant under any adjustment of the table, I journal
the stud T on which the cone pulley T is mounted, in a bearing or lever arm T
pivoted on the shaft K, and couple said stud T by a connecting rod V to the stud
or shaft on which the cone pulley S is mounted so that as the saw table is moved
end wise in either direction the lever arm T2 by means of said connecting rod will
turn about the centre K and the cone pulley T thus be maintained at the same
relative distance from the cone pulley S.
The feed rollers F are removable from the machine, and feed rollers other than
those shewn and either vertical or horizontal may be applied to the machine, the
horizontal feed rollers being driven off the feed roller shaft F by bevil wheels
somewhat in the ordinary manner.
When not required, the above parts may remain iuoperative, and being clear
of the saw table will admit of the machine being used for ordinary sawing
purposes.
Although I have described and shewn ny improvements as being applied to
circular saw benches having movable saw tables, it will be understood that the
same can be applied to circular saw benches having fixed saw tables, the radial
arm G and parts being arranged as shewn but separate from the table, and adapted
to be slided end wise in ways in the table or frame of the machine by a screw
actuated by hand wheel in manner similar to the adjustment of the sliding aw
table, the slot or opening B' in the saw table being made much wider to allow for
the extent of traverse of the radial arm in each direction, whilst the stud O is
made longer and the pulley P provided with flanges engaging the sides of the
rail P' so that it will remain on said rail and the stud slide end wise to and fro in
the said pulley when the radial arm is moved in either direction; the chain R
being, in this case, attached to the bearing G.
I am aware that radial arms, for adjusting or moving the feed rollers in circular
saw benches, towards or away from the canting fence, have heretofore been
employed, but they have been situated on, or over, the saw table, or arranged to
act above said table where they are in the way and possess disadvantages which
are avoided by arranging the radial arm underneath the saw table according to
my invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that, while
not confining myself to the precise details of construction of the radial arm G,
bearing or pedestal G secured thereto, and mechanism connected with said radial
arm, which may be varied somewhat from what is shewn and described, if desired,
without departing from the features of my invention, what I claim is :-
Firstly. In circular saw benches, a radial arm, such as G arranged underneath
the saw table, in the manner and for the purposes substantially as herein shewn
and described.
Secondly. In circular saw benches, the combination of a radial arm situated
underneath the saw table and carrying the shaft for imparting motion to the feed
roller shaft, said radial arm being adapted to move endwise either with or without
the saw table and a bevilting bearing or pedestal in which the feed roller shaft is
jourualled, secured on the end of said radial arm and adapted to be swivelled from
the vertical to any angular position within given limits, substantially in the manner
and for purposes herein shewn and described.
Thirdly. In circular saw benches, the general arrangement, construction and
combination of the radial arm G acting underneath the saw table parts connected
with said radial arm and mechanism for conveying motion to the feed rollers,
substantially as herein shewn and described.
Fourthly. In circular saw benches, the combination, with a radial arın such
as G arranged to act under the saw table and mechanism connected with said
radial arm for conveying motion from the driven cone pulley to the feed rollers
and movable with said radial arm in an end wise direction either with or without

page_text: the saw table, of a bearing or lever arm T' pivoted on the succeeding motion
shaft K' and carrying the shaft or stud on which the driven cone pulley T is
mounted and a rod V connecting said stud to the shaft on which the driving cone
pulley is mounted, in the manner and for the purposes substantially as herein shewn
and described.
