page_text: LETTERS PATENT to Edward Hutchinson, of the Firm of Pease,
Hutchinson, and Company, of Darlington, in the County of
Durham, Iron Manufacturers, for the Invention of "IMPROVEMENTS
IN THE CONSTRUCTION OF PLANING MACHINES.
PROVISIONAL SPECIFICATION left by the said Edward Hutchinson
at the Office of the Commissioners of Patents, with his Petition,
on the 25th February 1868...
I, EDWARD HUTCHINSON, of the Firm of Pease, Hutchinson, 'and
Company, of Darlington, in the County of Durham, Iron Manu-
facturers, do; hereby declare the, nature of the said. Invention. for.
"IMPROVEMENTS: IN THE CONSTRUCTION OF PLANING, MACHINES," to be. as,
follows:-
-
In planing machines constructed according to my Invention I cause
the article or articles to be planed to move continuously in one direction,
and employ as the planing or cutting tool a revolving disc fitted with
cutters on its side or face.
The article or articles to be planed is or are passed between onc.or.
more pairs of rolls capable of being adjusted by set screws or other

page_text: mechanism to any desired distance apart so as to suit the article or
articles to be operated on. One or more of these rolls is by power
applied in any convenient manner made to rotate and draw or feed the
said article or articles through the machine at a speed equal to the
cutting power of the revolving tool. The shaft or spindle of the
revolving tool which rests in bearings supported in stationary frame-
work is caused to rotate by suitable motive power; when the article to
be operated on is heavy or of great length I rest it on small antifriction
wheel carriages adapted to run on longitudinal parallel rails or on a
flat stationary table.
In adapting one of my machines for planing wrought-iron plates for
girders and such like work, more especially the booms or flanges of girders
which are composed of a number of plates required to be of the same
width, and for this purpose my improvements are specially applicable,
I employ two revolving cutting tools preferably placed on the same
spindle and adjust them at the required distance apart, so that as the
plates are fed or drawn through by the rolls, two pairs of rolls geared by
worms and wheels being used, both sides thereof will be planed at the
same time.
My said planing machines can be used with great advantage in com-
bination with the multiple drilling machine for which Provisional
Protection is applied simultaneously with this.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Hutchinson in the Great Seal Patent
Office on the 25th August 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
HUTCHINSON, of the Firm of Pease, Hutchinson, and Company, of
Darlington, in the County of Durham, Iron Manufacturers, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her 3
Letters Patent, bearing date the Twenty-fifth day of February, in the
year of our Lord One thousand eight hundred and sixty-eight, in the
thirty-first year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Edward Hutchinson, Her special license
that I, the said Edward Hutchinson, my executors, administrators,

page_text: and assigns, or such others as I, the said Edward Hutchinson, my
executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN THE CONSTRUCTION OF PLANING MACHINES," upon the
condition (amongst others) that I, the said Edward Hutchinson, my
executors or administrators, by an instrument in writing under my, or
their, or one of their hands and scals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Edward Hutchinson, do hereby
declare the nature of my said Invention, and in what manner the
same is to be. performed, to be particularly described and ascertained
in and by the following statement thereof, reference being had to the
accompanying Sheet of Drawings, and to the figures and letters marked
thereon, that is to say :-
In planing machines constructed according to my Invention I cause
the article or articles to be planed to move continuously in one direction,
and employ as the planing or cutting tool a revolving disc fitted with
cutters on its side or face.
The article or articles to be planed is or are passed between one or
more pairs of rolls capable of being adjusted by set screws or other
mechanism to any desired distance apart so as to suit the article or
articles to be operated on.
One or more of these rolls is by power
applied in any convenient manner, made to rotate and draw or feed
the said article or articles through the machine at a speed equal to
the cutting power of the revolving tool. The shaft or spindle of the
revolving tool which rests in bearings supported in stationary framework
is caused to rotate by suitable motive power; when the article to be
operated on is heavy or of great length, I rest it on small antifriction
wheel carriages adapted to run on longitudinal parallel rails or on a
flat stationary table.
In adapting one of my machines for planing wrought-iron plates
for girders and such like work, more especially the booms or flanges

page_text: of girders, which are composed of a number of plates required to be of
the same width, and for this purpose my improvements are specially
applicable, I employ two revolving cutting tools preferably placed on
thic same spindle, and adjust them at the required distance apart, so that
as the plates are fed or drawn through by the rolls, two pairs of rolls
geared by worms and wheels being used, both sides thereof will be
planed at the same time.
My said planing machines can be used with great advantage in com-
bination with the multiple drilling machine for which Letters Patent
were granted to me on the 25th February, A.D. 1868, No. 622.
On the Sheet of illustrative Drawings appended hereto, Fig. 1 is a side
elevation; Fig. 2, a vertical transverse section at the line A, B, and
Fig. 3, a longitudinal vertical section at C, D, all of a machine for
operating on both sides of the article or material to be planed (a
number of flat plates are shewn), by means of two rotating cutting
tools. In these views like letters and figures denote the same parts.
a, denotes the first motion pinion and shaft; b, the driving wheel on
the second motion shaft c; d, pinion on second motion shaft; e, driving
spur wheel on the main shaft f; the said main shaft f is screwed for
the purpose of adjusting the rotating discs g at the required distance
apart, the said rotating discs g being securely fixed by the screwed key
glut piece sliding in a keyway in the main shaft f; j, the cutters
projecting from the face of g and secured cach by a screwed key j; k,
the frame of the machine; 1, plate gripping or binding and feeding rolls
preferably made of wrought iron; m, screws for binding or pressing the
plates between the rolls ; n, worm wheels on 7; o, worm shafts with
right and left-handed worms o¹ thereon; p, bevel wheels working the
worm shafts o and worm shafts o'; q, intermediate feed motion shaft; ",
worm wheel on intermediate shaft q driven by a worm on the end of
the second motion shaft c. The parts n, o, o³, p, q, and r, just referred
to are the feed mechanism; 8, clamp carriers securing the plates
together and carrying them forward to the machine, they are fitted
with wheels & which run on the gautress or guide rails t, and each
such carrier 8, 8¹, is removed as it approaches ; u, bearing shaft free
to rotate in its bearings, fitted with rolls u adjustable to the width
of the plates, these rolls serve to bear up the plates or articles and
receive the direct pressure exerted by the rotating cutting tools when at
work; v, bearing bar with width adjustable flange picces ¹ to deliver

page_text: C
the plates or articles evenly; 20, foundation stones; x, plates being
operated on. To adjust the machine for use it is necessary to set the
rotating cutting tools g, j, the rolls u', and the flanges v' at the required
distances apart to secure the plates & in the desired position over each
other within and by the clamp carriers 8, s³, and then run the said
plates forward through beneath the binding and feed rolls 1, which
rolls are by the set screws m set so as to bind the parts tightly together.
The above adjustment having been effected and the machine set in
motion, the action is as follows:-The rolls 7, they being made to rotate
as is indicated by the arrows in opposite directions by the worms o' on
the shaft o, the bevel wheels P, the intermediate shaft q, the wheel r, and
the worm on the end, of the second motion shaft c, feed or impel forward
the plates x, and the cutters j projecting from the face of g cut off
as they rotate the required thickness from the edges of the plates and
deliver them with both sides planed clean and true.
.
It will be obvious that when only one side of a plate or plates or
article or articles is to be planed, that only one rotating cutting tool
would be employed.
And when my said improvements with either one or two rotating
cutting tools are employed to act simultaneously on the same plates or
articles or length thereof with the improvements in multiple drilling
machines, for which Letters Patent bearing date the 25th February,
A.D. 1868, No. 622, were granted to me, then the said multiple drilling
machine can be placed so as to act on the plates or articles before they
enter between the feed and binding rolls, or preferably after they
leave the machine from between the flanges v¹, and in this latter
case clamp carriers similar to s, s¹, or other suitable clamps, can be
used to bind the plates together and carry them through the said drilling
machinery.
Having now described the nature of my said Invention and par-
ticularized the same by details which I have found to answer well
in practice, I would have it understood that I do not confine myself
to the detail of every part herein mentioned and delineated by the
Drawings, what I claim as of my Invention in the construction of
planing machines is,―
First. Causing the plates or articles to be planed to travel, and
employing rotating cutting tools to plane both edges or sides at the
same time as herein described and illustrated by the Drawings.

page_text: Second. The combination and arrangement of parts substantially as
herein described and illustrated by the Drawings, whereby whilst the
plates or articles are fed along or caused to travel a rotating cutting tool
carried in bearings resting in a stationary frame is made to plane one
side or surface true and clean.
Third. The combination in planing machines, in which the article to
be planed is made to travel, of the clamp carriers 8, 81, for the purpose
set forth as herein described and shown on the Drawings.
Fourth. The rotating cutting tools ġ, j, in combination with the
adjustable feed and binding screws for the purpose herein set forth, as
illustrated by the Drawings.
Fifth. Machines with any or all of the above improvements to act
simultaneously with my Patent multiple drilling machine herein-before
referred to on the same article or articles, substantially as described.
In witness whereof, I, the said Edward Hutchinson, have here- 1
unto set my hand and seal, this 22nd day of August, in the
year of our Lord One thousand eight hundred and sixty-eight.
