Year: 1874

page_text: LETTERS PATENT to James Butler (of the Firm of Messieurs Dennis
and Butler), of Halifax, in the County of York, Machine Makers,
for the Invention of "IMPROVEMENTS IN MACHINERY FOR PLANING AND
SHAPING METALS."
Sealed the 9th March 1875, and dated the 10th September 1874.
PROVISIONAL SPECIFICATION left by the said James Butler at the
Office of the Commissioners of Patents, with his Petition, on the
10th September 1874.
I, JAMES BUTLER (of the Firm of Messieurs Dennis and Butler), of
Halifax, in the County of York, Machine Makers, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR
PLANING AND SHAPING METALS," to be as follows :-

page_text: planing and shaping metals) so as to accomplish an increased quantity
of work within a given time, the cutting tool or tools operating during
both the outward and return movements thereof or of the table carrying
the metal to be planed or shaped.
The table carrying the metal to be planed or shaped is moved by gear
or other mechanism at an uniform speed during the outward and return
movements, or the tool or tools may be traversed. A cutting tool some-
what of the form of the letter T inverted, and having two cutting edges
or faces is secured, as usual, to the "tool box," the tool holder being
capable of slight oscillation on a pin or bolt passed through about
midway its length, so as to admit of or to allow the cutting edge of the
tool not in operation to tilt slightly, and prevent its bearing and rubbing
on the metal being planed or shaped, or two single tools placed in the
tool box back to back may be employed, and these may be adjusted each
to cut or plane alike or one more than the other, that is to say, one may
be a roughing tool and the other a smoothing tool, and there is a double
"setting up when" employed.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Butler in the Great Seal Patent Office on the
10th March 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
BUTLER (of the Firm of Messieurs Dennis and Butler), of Halifax, in
the County of York, Machine Makers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of September, in the year
of our Lord One thousand eight hundred and seventy-four, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said James Butler, Her special licence
that I, the said James Butler, my executors, administrators, and
assigns, or such others as I, the said James Butler, 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

page_text: vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS.IN
MACHINERY FOR PLANING AND SHAPING METALS," upon the condition (amongst
others) that I, the said James Butler, my executors or administrators, by
an instrument in writing under my, or their, or one of their hands
and seals, 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 James Butler, 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, that is to say :-
This Invention has for its object the construction, application, and
use of a cutting tool or tools and apparatus therewith connected (for
planing and shaping metals) so as to accomplish an increased quantity
of work within a given time, the cutting tool or tools operating during
both the outward and return movement thereof or of the table carrying
the metal to be planed or shaped.
The table carrying the metal to be planed or shaped is moved by gear
or other mechanism at an uniform speed during the outward and return
movements, or the tool or tools may be traversed. A cutting tool some-
what of the form of the letter T inverted, and having two cutting edges
or faces, is secured, as usual, to the "tool box," the tool holder being
capable of alight oscillation on a pin or bolt passed through about
midway its length, so as to admit of or to allow the cutting edge of the
tool not in operation to tilt alightly, and prevent its bearing and
rubbing on the metal being planed or shaped, or two single tools placed
in the tool box back to back may be employed, and these may be adjusted
each to out or plane alike, or one more than the other, that is to say, one
may be a roughing tool and the other a smoothing tool, and there is a
double "setting up motion "employed.
Such being the nature and object of this Invention I will now proceed
to describe the same in detail, and in order that the same may be fully'
understood, I have hereunto annexed a Sheet of Drawings illustrative of

page_text: the same letter referring to the same part in the various views or
figures.
Fig. 1 is a side elevation partly in section; Fig. 2 is a plan view;
Fig. 3 is an elevation of detail or part of the apparatus.
A is a shaft extending across the "cross slide" of the machine, which
shaft receives partial rotary motion from bell-crank lever by the ordinary
feed motion; B is an arm on this cross shaft, which is connected by
pin C to the looped or eye D of the rod E, which passes through the
bosses of the ordinary setting down motion; the other end of the rod E
is connected by the link F (turning on the fulcrum G) with the pusher
and puller H connected with the tool holder J, in which are the
tools K, K, placed back to back, and secured by the set screws L, L,
the tool holder J being free to oscillate slightly on the fulcrum bolt M,
so as to admit of the tool when for the time being not in actual operation
tilting, that is to say, during the return stroke or traverse.
The action of the apparatus is as follows:-The tool K (see Fig. 1) is
in position for cutting, whilst the tool K¹ is tilted clear of the work on
the return stroke or traverse of the tools K¹ will be the active cutter, K
having tilted on its fulcrum M, as shewn by dotted lines, the tilting of
the tools being effected by means of the bell-crank lever, and the several
connections herein referred to and shewn in the Drawings.
It will be understood that when applying this Invention to the shaping
machine, on which there is no cross slide or setting down motion, the
link F will be connected by rod to the "ram or other going part of the
machine.
د,
Having thus described the nature and particulars of this my said Inven-
tion, together with the manner in which the same is to be performed or
carried into practical effect, I would remark that I lay no claim to any
of the parts herein referred to when considered separate from the special
adaptation and arrangement herein shewn and described, but what I do
claim is,―
Firstly. The tools K, K, combined and oscilating on the bolt M, as

page_text: Secondly. The combination and arrangement of parts or apparatus for
oscillating the box J and tools, as and for the purpose as herein described
and illustrated.
In witness whereof, I, the said James Butler, have hereunto set
my hand and seal, this Fifth day of March, in the year of our
Lord One thousand eight hundred and seventy-five.
Signed and sealed by the said
James Butler in the presence
of
GEO. BRIERLEY,
Solicitor,
Halifax.
