I JOHN MUTER WILSON of Warwick Street, Lever Street, Manchester, in the
County of Lancaster, Timber Merchant, Saw Mill Proprietor and Wood Turner, do
hereby declare the nature of this Invention to be as follows:-
My Invention relates to apparatus for planing wood and refers more particularly to
the types of machine in which the wood is passed over a fixed blade which dresses the
surface of the wood. In an existing machine of this description the wood is passed
over the said fixed blade by means of a revolving roller or of revolving rollers formed
of or covered with india rubber, but the use of this means for traversing the wood is
attended with certain disadvantages and is costly to maintain. According to my
invention instead of having one or more isolated rollers of rubber to traverse the
wood, I obtain the required result by means of a belt carried on pullies, the traversing
portion of the belt extending for some distance parallel with the table of the machine,
thus presenting an extended gripping surface to the wood. The belt may be carried
on three pullies the upper pulley being the driving pulley of the series or it might be
carried on more than three pullies or on two pulleys only and be driven in any
convenient manner. The belt is or may be composed of leather or of textile or other
suitable flexible material and is preferably prepared on the side intended to come in
contact with the wood, with a coating of glue or other suitable adhesive substance
sprinkled while warm with ground cork, or any other renewable dressing may be
used which will give a comparatively elastic gripping surface to the belt without
causing it to mark or injure the planed surface of the wood. The pullies which press
the belt upon the wood are carried in bearings capable of up and down movement
and are or may be weighted with weights or pressed downward by a spring against
the wood, so that in using my improved apparatus pieces of wood varying in thickness
may successively be passed through the machine without necessitating corresponding
adjustments and without injury to the traversing belt or to the blade. When the
dressing on the gripping surface of the belt becomes worn by use it can easily be
renewed and the belt itself can also be replaced at a slight cost when worn. I render
the pullies adjustable toward and from each other so as to put any desired strain upon
the belt. The invention is applicable to machines having revolving cutters and fixed
blades in combination.

Improvements in Apparatus for Planing Wood.
1 JOHN MUTER WILSON of Warwick Street Lever Street Manchester in the
County of Lancaster Timber Merchant Saw Mill Proprietor and Wood Turner 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 and accompanying drawings:-
My Invention relates to apparatus for planing wood and refers more particularly to
the types of machine in which the wood is passed over a fixed blade which dresses
the surface of the wood. In an existing machine of this description the wood is
passed over the said fixed blade by means of a revolving roller or of revolving rollers
formed of or covered with india rubber. According to my invention instead of
having one or more isolated rollers of rubber to traverse the wood, I obtain the
required result by means of a belt carried on pullies, the traversing portion of the
belt extending for some distance parallel with the table of the machine thus
presenting an extended gripping surface to the wood. The pullies which press the
belt upon the wood are carried in bearings capable of up and down movement and are
or may be weighted with weights or pressed downward by a spring against the wood,
so that in using my improved apparatus pieces of wood varying in thickness may
successively be passed through the machine without necessitating corresponding
adjustments and without injury to the traversing belt or to the blade.
In order that my Invention may be fully understood I will now proceed more
particularly to describe the same with reference to the annexed drawing which is a
side elevation of my improved apparatus.
The machine is composed of a frame A which carries the mechanism. The table B
is planed and levelled so as to present a smooth and true surface. A plane-iron C
is fixed in the table B so as to act on the wood which is passed over the table in
the direction of the arrows. The improved arrangements for passing the wood over
the table and plane-iron are as follows:-At each end of the table are standards D to
which lever frames E are pivotted at F. Between the side members of the lever
frames E are pullies G of a breadth at least equal to that of the plane iron C. A
belt H passes under these pullies in the manner shewn and is driven by an overhead
pulley or by overhead pullies in the direction indicated by the arrows. To draw the
pullies G and the belt H toward the table so as to press on the wood being passed
through the machine I attach the ends of the lever frames E by means of links I to
weighted levers J the said levers J being pivotted at K to a bracket or projection
from the frame A and having weights L suspended at their outer ends. Stops M are
secured to the links I so as to prevent the belt from approaching the table and knife
too closely. The belt is or may be composed of leather or of textile or other suitable
flexible material and is preferably prepared on the side intended to come in contact
with the wood, with a coating of glue or other suitable adhesive substance sprinkled
while warm with ground cork, or any other suitable and easily renewable dressing

page_text: may be used which will give a comparatively elastic gripping surface to the belt
without allowing it to mark or injure the planed surface of the wood. If thought
desirable I might introduce several presser pullies to press upon the portion of the
belting extending above the table between the pullies G, or I might arrange revolving
rollers beneath the belt and about level with the table to assist in carrying forward
the work or instead of such lower rollers I might employ a belt upon which the wood
might be laid to be carried forward over the knife. When the machine is in use the
wood is introduced at the end of the machine marked X and is slipped beneath the
traversing belt which carries it forward with considerable velocity over the table and
over the knife or plane iron C. The portion of belting extending between the pullies G
presents a considerable extent of gripping surface to the plank and carries it easily
through. The planks might be fed by hand or they might be fed automatically by
means of a feed platform N. This platform slides up and down in ways and is drawn
upward toward the table by counterbalance weights O the suspending chains from
which pass over the carrier pullies P and are attached to the sides of the platform N.
The said weights might however be replaced by springs used either in compression or
in tension. The ends of a pile of wood to be dressed are laid on the platform. The
weights or springs lift the platform and the wood is successively brought in contact
with the traversing belt and successively drawn over the table and knife and shot into
a receptacle at the other end or removed by an attendant as desired. My invention is
also applicable to machines having revolving cutters and fixed blades used in
combination.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
(1) The general arrangement and combination of apparatus for planing wood
substantially as described and shewn.
(2) In wood planing apparatus of the indicated description the endless belt for
traversing the wood over the table and knife arranged and operating substantially as
hereinbefore described and shewn.
(3) In wood planing apparatus of the indicated description the sliding table raised
by weights or springs for feeding planks or boards to the apparatus automatically and
in succession substantially as hereinbefore described and shewn.
