PROVISIONAL SPECIFICATION.
Improvements in Fixed Knife Planing Machines.
I, BOOTH SUTCLIFFE, of Range Bank, Halifax, in the County of York, Wood
Working Machine Maker, do hereby declare the nature of this invention to be as
follows:-
Upon a suitable frame are spring or other bearings carrying a shaft upon which
is a roller revolving above the table upon which the laths or pieces of wood are
fed to the stationary knife which is placed at an angle immediately under the feed
roller.
The lags or woods are fed to the knife by means of endless chains and chain
wheels, the chains carrying cross bars at sufficient distances apart to suit the lengths
of wood being planed.
The woods are piled upon the table and a large enough hole is left in front of
the feed roller to allow the woods or lags, (one at a time) to be brought through
by the bars to the knife, they are then dropped at the other side, the table is
raised and lowered as in the ordinary planing machine by screwed shafts and
bevel wheels, the chain wheels are driven by belt which passes over a taking up
pulley carried in the slot of a bracket, so that the strap can be kept tight and
adjusted by screw as and when required.
The feed roller revolves the same way as the wood is fed, and assists it.

COMPLETE SPECIFICATION.
Improvements in Fixed Knife Planing Machines.
I BOOTH SUTCLIFFE of Range Bank Halifax in the County of York, Wood-
working Machine 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 :-
DESCRIPTION OF DRAWINGS.
Fig. 1 is a side elevation of my improved fixed knife planing machine.
Fig. 2 is a plan of Fig. 1.
Upon a suitable frame A are spring or other bearings B, carrying a shaft C,
upon which is a roller D revolving above the table E, upon this table are placed
the laths or other pieces of wood to be planed, after which they are fed to the
stationary knife F, which is placed at an angle immediately under the feed
roller D.
The lags or other wood are fed to the knife by means of endless chains G, and
chain wheels H, the chains carry cross bars J, at sufficient distances apart to suit
the length of the wood being planed.
The lags or other wood are piled upon the table E, and the table adjusted to
the rectangular frame K of the machine, leaving sufficient space for one lag at a
time to pass to the knife. As the cross bars J upon the chains G, revolve, they come
in contact with the bottom lag, lath, or board of the pile carrying same to the feed
roller D, which presses it upon the knife, thereby taking off a nice shaving from
that side of the board, after the lag, lath, or board has been planed it is carried

page_text: forward and dropped at the end of the machine; this is continued until the whole
pile of boards have been planed.
The table is raised and lowered as in the ordinary planing_machine, by screwed
shafts and bevel wheels, the chain wheels are driven by belt L, which passes over
a taking up pulley M, carried in a slot N, of the bracket P, so that the driving
belt may be kept tight, and adjusted by screw R and hand wheel S as and when
required.
The feed roller revolves the same way as the wood is fed, thereby assisting it
forwards to the knife.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. Feeding numbers of lags, laths, or boards to fixed knife planing machines for
the purpose such as shown and described.
2. In fixed knife planing machines the use and employment of feed roller D
mounted in spring bearings B, endless chains G, chain wheels H, and cross bars J,
operated in the manner and for the purposes such as shown and described.
3. In fixed knife planing machines the use and employment of a taking up or
tension pulley M, adjusted in the manner and for the purposes such as shown and
described.
Dated this Twenty-first day of July 1891.
