IMPROVEMENTS IN MACHINERY FOR SAWING WOOD
Year: 1880

page_text: LETTERS PATENT to John Pickles and George Pickles, of Hebden Bridge, in
the County of York, Machine Makers, for an Invention of "IMPROVEMENTS IN
MACHINERY FOR SAWING WOOD."
PROVISIONAL SPECIFICATION left by the said John Pickles and George
Pickles at the Office of the Commissioners of Patents on the 28th May 1880.
JOHN PICKLES and GEORGE PICKLES, of Hebden Bridge, in the County of York,
Machine Makers. "IMPROVEMENTS IN MACHINERY FOR SAWING WOOD."
This Invention relates to machinery for sawing wood in which circular saws are
employed, and the object of the improvements is to keep the feed roller or rollers
and fence in the same relative positions to the circular saw or saws, whatever may
be their diameter. The improvements consist in having the table or top loose and
capable of sliding in suitable bearings, so that when the size or diameter of the saw
or saws is changed, the feed roller or rollers and fence which are connected to the
sliding table always maintain the same relative positions to the saw or saws. The
table or top is caused to move backward and forward by means of a screw, rack
and pinion, or other mechanical equivalent.
Instead of moving the table the shaft of the circular saw or saws may be
arranged to slide backward and forward in suitable bearings, the length of the
driving strap being regulated by means of an adjustable pulley or pullies.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Pickles and George Pickles in the Great Seal Patent Office on
the 27th November 1880.

top is caused to move backward and forward by means of a screw, rack and pinion,
or other mechanical equivalent.
In order that the Invention may be better understood, we herein give reference
to the accompanying Sheet of Drawings, wherein Fig. 1 is a front elevation of a
circular saw wood cutting machine with our improvements applied thereto; Fig. 2
is a plan view, and Fig. 3 an end elevation. A is the circular saw fixed upon the
shaft B working in stationary bearings C in the ordinary manner; D are the feed
rollers, and E the fence, both of which are attached to or connected with the table
top F, which is loose and capable of sliding backward and forward in V or other
suitably shaped bearings (shewn in end view Fig. 3). A boss or nut is provided
on the underside of the loose table and top of the frame work through which the
screw G passes, and by means of hand wheel H the table top is moved either
backward or forward, as and when required to suit the diameter of saw.
block supporting the feed roller D can be moved in and out towards the fence to
suit different thickness of timber, and this is accomplished by means of rope d
and weight e, or other suitable means. It will thus be seen that when the
diameter of the saw is changed that the feed rollers and fence which are attached
to the top of the table can be moved bodily without disturbing their relative
positions, nearer to or further from the centre of the saw, and this arrangement is
especially useful when cutting twisted or warped timber, owing to the pressure
against the said timber being brought close to the periphery of the saw, wheroby
the wood is cut parallel to the face of the fence.
The
Our Invention is equally applicable to machines where the rope feed and side
pressure lever is used in conjunction with the fence instead of the feed rollers; this
method is illustrated in Figs. 4 and 5, where I is the side pressure lever carrying a
friction roller J, all of which are attached to the top of the table and capable of
being moved nearer to or further from the saw, as previously explained.
Having now described the nature of our Invention, and the manner in which
the same is to be performed, we wish it to be understood that we do not limit
ourselves to the precise details herein before described and illustrated in the
accompanying Drawings, as the same may be varied without departing from the
nature of our Invention, but we claim as our Invention,-
The combination and arrangement of the parts herein shewn and described,
whereby feed rollers and fence can be moved nearer to or further from the saw
without their relative positions being disturbed.
In witness whereof, I, the said George Pickles, for and on behalf of the said
John Pickles, have hereunto set my hand and seal, this Twenty-fourth day
of November, in the year of our Lord One thousand eight hundred and
Witness,
CHARLES AINLEY.
GEORGE PICKLES. (L.S.)
