Year: 1867

page_text: LETTERS PATENT to Henry Allason Fletcher, of the Lowca Engine Works,
near Whitehaven, for the Invention of "IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR BORING AND PLANING METALS."
Sealed the 6th August 1867, and dated the 8th February 1867.
PROVISIONAL SPECIFICATION left by the said Henry Allason Fletcher'
at the Office of the Commissioners of Patents; with his Petition, on the
8th February 1867.
I, HENRY ALLASON FLETCHER, of the Lowca Engine Works, near White-
haven, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR BORING AND PLANING METALS," to be
as follows:
This Invention consists in combining a boring and a planing machine
together in such a manner that steam-engine cylinders and other similar.
objects can be both bored and planed simultaneously, and with one setting.or
adjustment on the machine, and may be adopted, firstly, to planing machines.
on which the work traverses to and fro during the operation of planing; and,,
secondly, to planing machines in which the work is fixed and the cutting.
tool or tools are traversed to and fro over the work.
According to one mode of carrying out this Invention, as applied to a
planing machine with traversing table and stationary cutter, it is proposed to
adopt an ordinary or other boring bar with head to the table of the planing.

page_text: machine, such boring bar working in suitable bearings contained in brackets
or pillow blocks bolted to the surface of the table, so as to travel along with
it. The boring bar is rotated by gearing from a driving shaft carried in fixed
bearings and provided with fast-and-loose pullies such driving shaft sliding
to and fro longitudinally through the driving pullies or through the pinion, so
as to follow the motion of the table.
In combining the boring apparatus with a planing machine having a fixed
table the boring apparatus will of course, not require the sliding driving shaft,
and all the boring gear will be attached to the table.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed 1
by the said Henry Allason Fletcher in the Great Seal Patent Office on
the 7th August 1867.
TO ALL TO WHOM THESE. PRESENTS SHALL COME, I, HENRY
ALLASON FLETCHER, of Lowca Engine Works, near Whitehaven, in the County
of Cumberland, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of February, in the year of our
Lord One thousand eight hundred and sixty-seven, in the thirtieth year
of Her reign, did, for Herself, Her Heirs and successors, give and grant
unto me, the said Henry Allason Fletcher, Her special license that I, the
said Henry Allason Fletcher, my executors, administrators, and assigns, or
such others as I, the said Henry Allason Fletcher, my executors, adminis-
trators, or 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 MACHINERY OR APPARATUS FOR BORING AND
PLANING METALS," upon the condition (amongst others) that I, the said Henry
Allason Fletcher, my executors or administrators, by an instrument in writing
under my hand and seal, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be per-
formed, 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 Henry Allason Fletcher, do hereby.
declare the nature of my said Invention, and in what manner the same

page_text: is to be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the accompanying Drawings,' and
to the letters and figures marked thereon, that is to say :-
My said Invention consists in combining a boring and a planing machine
together in such a manner that steam-engine cylinders and other similar
objects can be both bored and planed simultaneously, and with one setting or
adjustment on the machine, and may be adapted, firstly, to planing machines
in which the work traverses to and fro during the operation of planing; and,
secondly, to planing machines in which the work is fixed and the cutting
tool or tools are traversed to and fro over the work.
According to one mode of carrying out this Invention, as applied to a
planing machine with traversing table and stationary cutter, it is proposed to
adapt an ordinary or other boring bar to the table of the planing machine;
such boring bar working in suitable bearings contained in brackets or pillow
blocks bolted to the surface of the table, so as to travel, along with it. The
boring bar is rotated by gearing from a driving. shaft carried in fixed bearings,
and provided with fast-and-loose pullies, such driving shaft sliding to and fro
longitudinally through the driving pulleys or through the pinion, so as to
follow the motion of the table.
In combining the boring apparatus with a planing machine having a fixed
table the boring apparatus will, of course, not require the sliding driving shaft,
and all the boring gear. will be attached to the table.
And in order that my said Invention may be understood I shall now
proceed more particularly to describe the same, and for that purpose shall
refer to the several Figures on the annexed Sheets of Drawings, the same
letters of reference indicating corresponding parts in all the corresponding
Figures.
Figure 1 (Sheet 1) of my Drawings represents an elevation of a combined
boring and planing machine, wherein the table is fixed, and the cutting tool
for planing moves over the table and along the work operated upon; Figure 2
is a corresponding plan of the same, and Figure 3 (Sheet 2) is an end view
thereof.
In these views a, a, is the framing of the machine, and 6 is the fixed table,
upon which the work to be planed and bored is secured; this table carries
also the boring bar c; d, d, are the moving heads of the machine which carry
the cross slide e, similar to that of an ordinary planing machine, and mounted
with a tool box in the usual manner; these moving heads slide in V grooves,
and are each driven by means of a screw f, a flange underneath the heads
preventing them from rising.

page_text: In Figure 4 (Sheet 2) I have represented a plan of a combined planing
and boring machine, in which the work is traversed to and fro under the
cutting tool for planing during the operation of boring, the two operations of
planing and boring being carried on simultaneously; this machine consists of
an ordinary planing machine with traversing table having a boring apparatus
combined therewith. 9 is the traversing bed or table, to which the boring
bar with the principal portion of its driving apparatus is fixed, and which
is driven by means of the pulley or conej, through which the grooved driving
shaft passes and works to and fro with the reciprocating motion of the table
of the machine; k, k, are the fixed standards of the machine shown in cross
section for carrying the cross slide and tool box.
I may here observe that although the accompanying Drawings show only.
two modes or methods of carrying out my said Invention I do not confine or
restrict myself to the peculiar and special arrangements shown, so long as the
essential feature of my Invention be retained.
Having now described and particularly ascertained the nature of my said
Invention, and the manner in which the same is or may be used or carried
into effect, I would observe in conclusion that what I consider to be novel
and original and therefore claim as the Invention secured to me by the herein-.
before in part recited Letters Patent is, the construction and use of combined
machines capable of simultaneously boring and planing with one setting of
the work articles of metal requiring to be bored and planed, substantially as,
herein-before described.
In witness whereof, I, the said Henry Allason Fletcher, have to this:
my Specification set my hand and seal, the Fifth day of August, One
thousand eight hundred and sixty-seven.
HENRY ALLASON FLETCHER. (L.S.)
