PROVISIONAL SPECIFICATION.
Improvements in Machinery for Cutting Wood and other
Substances.
THOMAS YOUNGER Packing Case Manufacturer Leeds in the County of York
do hereby declare the nature of this invention to be as follows:-
This invention relates principally to machines and engines combined used for
cutting wood and other materials.
My invention is to fix the cutter holder, (to which are fixed the cutters, or
cutter,) to any motive power engine piston rod, or cross head, by this arrangement
the engine is converted into a cutting machine.
The wood or other substances to be operated upon, after being cut into suitable
lengths, are placed in a trough and propelled forward under the cutter by suitable
mechanism.

Improvements in Machinery for Cutting Wood and other
Substances.
I, THOMAS YOUNGER of 24 Hope Street, Leeds, in the County of York, Box
Maker, 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 relates to improvements in machinery or apparatus for cutting
wood and other substances; and its object is to combine such machines with an
engine driven by steam, gas, hydraulic, pneumatic, or other pressure, whereby the
primary power may be employed for operating the cutters of such machines, and
the fly wheel of the engine utilized as a driving pulley for communicating motion to
other machines.
In the drawings hereunto annexed I have shown the invention applied to a
machine such as is employed for cutting or chopping firewood, but I distinctly wish
it to be understood that it may be applied to other machines in which a reciprocating
cutter may be actuated directly from the cylinder of the engine.
In the drawings:-
Fig. 1 is a side elevation and Fig. 2 an end elevation of a combined steam engine
and firewood cutting machine.
A is the bedplate on which are mounted the standards B. On the top of the
standards B is fixed a steam cylinder C provided with covers C* a valve chest C'
and inlet C and exhaust C'. In the cylinder C reciprocates a piston C' provided
with a piston rod C' which passes through the usual gland C. A valve not shown
in the drawings reciprocates in the valve chest and it is operated by an eccentric, and
strap D mounted on the fly wheel shaft E through rod D' and spindle D³. The fly
wheel shaft is carried in suitable bearings F provide on or fixed to the standards B.
On the shaft E is mounted the fly wheel G (which may also be used as a driving
pulley) and a disc H armed with a crank pin H' which is connected by a rod I with
Price 8d1

page_text: a pin or stud fixed to the block attached to the end of the piston rod C³ and
arranged to reciprocate in slides formed in the standards B.
All the above described parts together with the governors not shown in the
drawings may be of any ordinary and well known construction.
To the sliding block K is fixed the cutter L which may be in the form of the
ordinary and well known construction of V knife.
Below the cutter Lon suitable framework M, fixed to the bed plate A, is mounted
the feed trough N provided with a moveable side O which is intermittently opened
and closed by means of a lever O¹, mounted on a shaft O' carried in bearings m m
on the framework M and arranged to engage with a boss O³ formed on the
adjustable side O. On the shaft is a second lever O' longer than the lever O¹,
and which is arranged to engage with or to be actuated by the heel O' of a tappet
lever O, pivoted at O', to the standard B. The front end of the lever O, is
actuated by a cam P mounted on the shaft E whenever it is required to open and
close the side O. In front of and either separate from or forming part of the feed
trough N is a pair of feed rollers Q, Q', having fluted or rough peripheries. The
feed rollers are geared together by spur wheels R and so arranged so that the
bearings of the upper roller Q may slide in the framework Q². In order that
the upper feed roller Q¹ may automatically adjust itself to the varying thicknesses
of material operated upon whilst the machine is at work, through each of its
bearings are passed two bolts Q. The bolts in the bearings are connected together
by the fixings Q for supporting a weighted lever Q5 pivoted to one of the
standards B. The required intermittent rotary motion for feeding purposes is
imparted to the bottom feed roller Q from a ratchet wheel S mounted on the
shaft Q on which the roller Q is fixed, one end of which is carried by the
bearing Q' fixed to the standard B. On the same is also mounted loosely a lever T
carrying a pawl T', which engages with the ratchet wheel S and which is also
jointed to the end of a rod T operated by an eccentric U mounted on the
shaft E.
The material to be operated upon is cut into suitable lengths and placed with the
grain vertically within the feed trough N and between the feed rollers Q. Q', the
top roller being retained to its work by the weighted lever Q as described.
The side O is held in position by the levers O¹, O+ and O, and it is only released
and moved outwards by the cam P when it is required to feed the material forward.
The steam or other pressure, is admitted through inlet C to the valve chest C' and
from thence to the cylinder C which causes the piston C' to reciprocate therein for
operating the slide block K and cutter L for dividing the material into say ordinary
firewood. At the same time motion is conveyed from the slide block K through
connecting rod I to the disc H whereby a rotary motion is imparted to the shaft E
and eccentrics and cam mounted thereon for operating the valve and the feed
mechanism.
When desired the cylinder, cutter and other parts of the machine may be
arranged to work in a horizontal instead of the vertical position shown in the
drawings.
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 :-
1. A machine such as described for cutting wood and other substances said
machine baving a reciprocating cutter fixed to a sliding block mounted on the end
of the piston rod of a steam or other cylinder in combination with feed mechanism
substantially as and for the purposes described and illustrated in the accompanying
drawings.
2. In a machine such as described for cutting wood and other substances in which
the cutter is fixed directly to the piston rod of a steam or other cylinder the
combination of the said cylinder, piston, piston rod, valves, and cutter with the feed
trough N having a moveable side O. the feed rollers Q. Q' and the mechanism

page_text: described for operating the said side O. and the feed rollers substantially as
described and illustrated in the drawings.
3. The arrangement and combination of the parts forming the improvements in
machinery for cutting wood and other substances substantially as described and
illustrated in the accompanying drawings.
