Improvements in Compound Machines for Planing, Cutting, or
Shaping Strips or Broad Pieces of Wood.
I, GEORGE PICKLES, of the Firm of John Pickles and Son, of Hanging Royd
Iron Works, Hebden Bridge, in the County of York, Saw Mill Engineers, do hereby
declare the nature of this invention to be as follows:-
My invention relates to compound machines for planing, moulding and cutting
either narrow or broad lengths of wood and in constructing a machine according
to my invention I employ four top and two bottom feeding rollers upon separate and
independent axles so that each top roller can be adjustable for different thicknesses
of wood and I combine with these four feed rollers, four rotary cutters placed upon
vertical spindles, one pair of cutters operating upon two sides of one length of
wood and the other pair of cutters also operating upon two sides of another length of
wood but I so arrange the said cutters in headstocks on two separate cross-
slides that each pair are either in line or preferably not lineable or opposite each
other but at an angle thereto so that the pressure of the cutters upon the wood
is divided. One or both of the two inner revolving cutters are fixed upon
detachable arbours so that they can be removed from the driving spindles in order
to permit the two outer cutters to operate upon two sides of a broad board.
The four top feed rollers (all of which are opposite each other) are at such a distance
apart from each other as to permit of them being removed and drawn off their
spindles so that feeding rollers of other shapes may be employed either bevel, round,
plain or other requisite shape.
In compound machines I employ two fences either both to right hand or both to
left hand when feeding for guiding the wood whereby I am permitted to operate upon
two diagonal lengths of wood without turning them over or upside down after leaving
the sawing machine which in long pieces of wood is very inconvenient.
In compound machines I employ a semicircular slot or other similar arrangement
in the top cutter headstock so as to be able to "cant" the said headstock and cutters
to suit irregular thicknesses of timbers.
In compound machines I provide means for regulating or adjusting the feeding
rollers, and this I effect by means of a hand wheel and screw for each pair of rollers
connected to one end of a chain passing over a pulley to a plate weight whilst the
said plate weight is also connected by vertical rods or suspenders to suitably shaped
arms which carry the feed rollers thus by operating the hand wheel in one direction
the feed rollers are lowered, and by operating the hand wheel in the opposite direction
the feed rollers are raised and made adjustable.

I, GEORGE PICKLES, of the Firm of John Pickles and Son, of Royd Iron Works,
Hebden Bridge, in the County of York, Saw Mill Engineers, 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 :-
My invention refers to machines for planing, moulding or cutting narrow or
broad pieces of wood and consists of the combination and arrangement of means for
compounding the machine in order that two narrow boards, each alike or differing
in size or shape, or one very wide board can be planed cut or moulded on all four
sides at one time, thus doubling the amount of work capable of being done on an
ordinary single machine, whilst less room is occupied and less power required than two
of such machines.
In order that my said invention may be fully understood reference is hereafter.
had to the annexed sheets of drawings forming a part of this specification, in
which
Fig. 1, is longitudinal elevation of so much of a compound or double moulding
and planing machine as is essential to shew the application of my improvements, a
portion being in section taken on line 1. 2. of Fig. 2.
Fig. 2 is plan of Fig. 1.
Figs. 3, 4, and 5 are details hereinafter referred to.
In constructing and arranging a double moulding and planing machine according
to my invention, I mount four top feeding rollers a, a, and a¹, a', and two bottom
feeding rollers b, b, upon separate and independent shafts or studs, those of the
former being journalled in bearings in the swings or links, c, hinged on central
studs d, d, carrying the intermediate pinions d', d', for giving rotary motion to the
top feed rollers, and those of the latter being journalled in bearings in the
framework e of the machine. The four top feed rollers are each adjustable to suit
varying thicknesses or inequalities of boards, or to enable two boards of unequal-
depth or thickness to be fed through the machine at the same time, the adjustment
of said rollers being effected by screws and hand wheels f, f', one for the right
and the other for the left hand pair of rollers, the screws being attached by
chains 9, , g², passing over pulleys h, h', to plate weights i, i, which are suspended by.
rods or suspenders j, j', secured to lugs on the ends of the swings c, c. By rotating
the. hand wheels in one or the other direction, the screws are caused to work
inward or outward and lower or raise the plate weights which, by means of the
connecting rods, lower or raise the two pairs of top feeding rollers corre-
spondingly, each said feed roller moving through the arc of a circle described from
the centres d, d, so that whatever adjustment may be made the gear wheels thereon
remain in mesh with the intermediate pinions d', d'.
Motion is communicated to the several feed rollers through the train of
gearing k.
The two pairs of top feed rollers a, a¹ are arranged opposite each other at a
distance apart slightly in excess of the length of the rollers so that said rollers can
be drawn off their spindles into the intervening space and removed from the machine
and other feed rollers either bevil or otherwise substituted therefor, the removal
_and_interchange causing little delay and no alteration or adjustment of parts
concerned.
In conjunction with the double or compound feed are four rotary side cutter or
chinner blooks and 11 11 pleand unan vastinul indlea
ll and having

page_text: cutters or chippers n of any appropriate form or design secured thereto. The said
.vertical spindles are journalled in bearings in headstocks o, o, o', o', which are
mounted respectively on two cross slides p, p', whereon the headstocks with their
spindles, can be slided to any position required and then secured by screws or like
means. In operating on two boards, the chipper or cutter spindles are preferably
arranged in pairs consisting of one front spindle m and one rear spindle m', as shewn
in the drawings, so that the cutters or chippers carried thereby will act upon the two
opposite sides of each board at two different points or in advance of each other
thus dividing the pressure of the side chippers on the wood. The same arrangement
also applies when a single wide board is passed through the machine. In this
case, however, only two cutter spindles-say, the two outer ones, are necessary, the
other two being slided to the extreme ends of the cross slides p, p, clear of the
work; or the cutter or chipper blocks not required can be removed entirely from
the machine they being secured on detachable arbors q (see Fig. 4) which are made
conical at their lower ends and are adapted to fit tightly in conical openings in
the ends of the cutter spindles into which they aro driven and can be easily
withdrawn when desired, a slight tap being all that is necessary to loosen them.
The boards are planed or moulded on both faces by cutters or chippers on the
bottom cutter spindler and the top cutter spindle s respectively, the latter being
journalled in bearings in the headstock t.
The said headstock is attached to a slide u adapted to be raised and lowered in
ways in the framework e by hand wheel and screw and is arranged to "cant" at an
angle to operate upon two boards of unequal thickness. For such purpose the
headstock is centred at t' to the slide u and secured at the opposite side by a nut
screwed on to a bolt or stud v which passes through a segmental slot v formed in
the slide shewn clearly at Fig. 3. By loosening the said nut the headstock will fall
or can be raised to any angle within the limits of the segmental slot to suit the
unequal thickness of the boards to be operated on.
In combination with the before described arrangement of side cutter spindles
and feed rollers I employ two fences w, wl, for determining the paths along which
the boards must traverse, these fences being arranged either both to right hand
or both to left band. In arranging said fences both to one hand, two diagonally
sawn lengths of wood can be fed to the machine without having first to turn
them over or upside down (after leaving the sawing machine) in order to get
them into the right position on the table of the planing or moulding machine as
will be understood by reference to Fig. 5, at the upper part of which is represented a
block of timber as it leaves the sawing machine having been sawn diagonally through
the line a, a, into two pieces y, y'. These two diagonally sawn lengths of wood can
be taken direct from the sawing machine and with very little movement laid straight
upon the table of the moulding machine and against the fences, as illustrated in
Fig. 5, this being an important advantage especially when long heavy boards are to be
operated upon.
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 what I
claim is :-
Firstly. In a moulding
or planing machine the combination, with four feed rollers
such as a, a, a, a', of four rotary side cutters or chippers on vertical spindles
substantially as shewn and described and for purposes set forth.
Secondly. In double moulding and planing machines the combination, with vertical
side cutter spindles, of two cross slides upon which the spindle headstocks are
mounted and can be adjusted laterally and the cutters arranged in pairs to act
opposite each other on two sides of the same board or in advance of each other,
anyone or two of said cutters being removable from the machine or clear of the
work when planing wide boards, substantially as herein shewn and described.
Thirdly. In double moulding and planing machines the combination, with four top
feed rollers mounted on separate and independent axles and arranged so as to be

page_text: easily interchangeable with other shaped feed rollers, of the means for adjusting said
rollers to suit different thicknesses of wood or feed forward two boards of the same or
unequal thickness substantially as herein shewn and described.
Fourthly. The combination with a double moulding and planing machine of the
centred or pivoted headstock carrying the top cutter spindle adapted to be canted to
any angle within the limits of a segmental slot in the manner and for purposes
substantially as shewn and described.
Fifthly. In a double moulding and planing machine the combination, with a double
feed and four rotary side cutters or chippers, of two side fences secured to the table
of the machine either both to right hand or both to left hand for purposes substantially
as described.
