IMPROVEMENTS IN APPARATUS FOR CUTTING OR PLANING WOOD
Year: 1884

page_text: I, PERCY RICHARDSON SHILL, of 6, Worlingham Road, East Dulwich in the
county of Surrey, Electrical Engineer, do hereby declare the nature of my inven-
tion for IMPROVEMENTS IN APPARATUS FOR CUTTING OR PLANING WOOD to be as
follows:-
The object of the invention is simplicity in construction, reduction of working
parts, and economy in use.
The improvements are particularly applicable to the planing of short lengths of
wood, but they are also applicable to plane any length or size.
In carrying out my improvements I use one or more endless Leather or Metallic
bands, or a suitable arrangement of links working on riggers or wheels at each end
of the main frame of machine.
One set of riggers or wheels I arrange in a movable or sliding frame, on a guide
or guides, attached or bolted to the main frame.
The object of the said movable or sliding frame, is to keep the endless band or
bands in tension, by means of an adjusting screw, spring, weight, or lever.
On the said band or bands, I arrange in a suitable manner by means of rivets,
bolts, screws, or clips, one or more metallic cross-bars or pickers.
When motion is given to the band or bands by hand, steam, or other power, the
cross-bars or pickers are carried round the riggers or wheels, and along the table or
top of machine, on which one or more pieces of wood rest, each cross-bar or picker
in its turn, pushes or forces the wood to be planed, forward against the knives or
cutters.

I PERCY RICHARDSON SHILL of 6 Worlingham Road, East Dulwich in the
County of Surrey, Electrical Engineer do hereby declare the nature of my said
Invention for " IMPROVEMENTS IN APPARATUS FOR CUTTING OR PLANING WOOD"
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
The object of this Invention is to reduce the number of working parts, and to
simplify the construction of that class of Machine used. for cutting or planing
wood.
In carrying this Invention into practice I arrange a framing of Cast Iron or
other suitable material, at one end of which is a bracket cast on the main frame to
support the main driving wheel or wheels for giving motion to the endless band or
bands. The said band or bands may be made of Leather, metal or a suitable
arrangement of links to receive the "pickers" or cross-bars hereinafter referred to.
The said band or bands are caused to run over riggers, pullies or wheels supported
in bearings on the aforesaid bracket or guides at either end of the said main frame.
On the back end of the machine or framing I arrange suitable guides for
receiving a yoke or frame to receive a corresponding wheel or wheels, the said yoke
or frame is arranged to slide on the guides to give tension to the endless band or
bands, the same being actuated by a screw or other suitable means.
"
و"
On the aforementioned bands which run parallel to each other, I fix at suitable
distances apart by means of rivets, bolts, screws or clips one or more inetallic
'cross-bars or pickers" which said "pickers as the bands rotate push or force
forward, against the edge of the knives or cutters, the wood to be planed.
At.the back end of the Machine I arrange a table of wood or iron bolted on the
main fraining, and which can be extended to any length required On either side
of the said table I arrange one or more uprights or walls of metal or other suitable
material to keep the pieces of wood in position, so that; as the endless band or
bands rotate or advance forward, the "pickers or cross-bars fixed thereto push
forward the under most piece of wood to be planed and allows the succeeding
pieces of wood to fall into position for the "pickers" or cross-bars to carry forward
in rapid succession to be planed. At the fore end of the table I. arrange an
adjustable shutter or slide bolted to one of the pressure frames or pillars (which
said pressure frames or pillars are hereinafter referred to) to suit the varying
thicknesses of wood, and preventing more than one piece (of wood) passing under-
neath its edge, to the cutters at the same time.
"
Within the aforesaid pressure pillars or frames I arrange a vertical slide for the
purpose of keeping the pieces of wood in contact with the knives or cutters as they
are carried forward, an even pressure being given through the said slide or slides
to the pieces of wood by means of a spring or springs or any other equivalent
One or more of the said pressure frames with a vertical slide or slides may
be used as found necessary.
means
.
The aforementioned knives or cutters are fixed or bolted in an angular position
to the main frame with their cutting edge pointing towards the advancing wood.

page_text: In order that my Invention may be more fully understood and explained in
detail I have hereunto annexed a Sheet of. Drawings on which letters of reference
are marked on corresponding parts on all the Figs. alike.
DESCRIPTION OF DRAWINGS.
Fig. 1. is a front elevation of the Machine arranged and constructed according to
my Improvements.
Fig. 2. is an end elevation of the same shewing the duplicate riggers, endless
bands, pickers or cross-bars, and the table supporting wood to be planed.
In these Figs. a is the framing of the Machine; b the knives or cutters fixed or
bolted thereto in an angular position, c and d are riggers around which travel the
endless band or bands the main rigger or wheel ƒ may be driven by hand or
steam power gare the guides at one end of the framing on which slides the yoke
or frame c, actuated by a screw and wheel h supporting rigger c. i are the side
walls of table supporting wood in position, j is the adjustable shutter or slide for
regulating the advance of each piece of wood to the cutters, k are the pressure
pillars or frames, and b.the vertical slide inside thereof, m are the springs for giving.
an equal pressure to the said vertical slide or slides l. n are the cross-bars or
'pickers" for pushing or forcing forward the wood to be planed.
"
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
First. The arrangement and use in a wood planing Machine of an endless band
or bands having fixed thereon at suitable distances apart detachable cross-bars or
pickers" in the manner and for the purpose as herein substantially described, set
forth and fully illustrated in the drawings.
"
Second. The arrangement, construction and use in a wood planing machine of
a pressure pillar or frame with a vertical slide, and spring for giving an uniform
pressure to the wood under operation as herein described set forth and illustrated.
Third. The use in a wood planing machine of a shutter or slide for regulating
the advance of the pieces of wood to be operated upon, as herein described set forth
and illustrated.
Fourth. The use in a wood planing machine of the yoke, or framing, sliding
telescopically on bars or guides (g) in the manner and for the purpose as herein
described and illustrated.
