Year: 1866

page_text: LETTERS PATENT to Elias Barlow, of Patricroft, in the County of Lancaster,
and William Nathan Dack, of the same Place, Engineers, for the Inven-
tion of "CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS POR PLANING
Sealed the 5th March 1867, and dated the 19th September 1866.
PROVISIONAL SPECIFICATION left by the said Elias Barlow and William
Nathan Dack at the Office of the Commissioners of Patents, with.
their Petition, on the 19th September 1866.
We, ELIAS BARLOW, of Patricroft, in the County of Lancaster, and WILLIAM
NATHAN DACK, of the same Place, Engineers, do hereby declare the nature of
the said Invention for "CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS
FOR PLANING METALS," to be as follows:-
The Invention relates to that portion of the machinery employed in planing
metals known as the tool and tool box, and consists, first, in the adaptation and
use of two tools or cutters to each down slide employed in the machine instead
of employing one tool as hitherto, the object being to effect the forward cut
with one tool and also to cut backwards on the return of the table with the
other; for this purpose the cutters are set or arranged in a separate tool box

page_text: side by side, or back to back, and are made adjustable both vertically and
laterally, either by mounting the boxes in slides to move both ways, or the
tool may be mounted in one vertical slide which is moved by a screw upwards
or downwards, the lateral movement or angle being controlled and determined
by two set screws, each separate tool being fitted with such compound adjust-
ment. We would here remark that the double tools are equally applicable
whether they be used stationary whilst the table and metal under operation is
moved, or the tools be traversed and the table be stationary.
A second part of the Invention relates to an improved arrangement of
gearing for effecting a variable traverse of the table or of the tools, and is
equally applicable either to the screw or rack and pinion motions, which are
well-known means of effecting the traverse of the table and tools. This novel
arrangement of gearing consists of a large bevel wheel, two bevel pinions,
and a pair of mitre wheels; the large bevel wheel and one mitre being secured
to the end of the screw shaft moving the table; into this large bevel wheel
the driving pinion gears, the other bevel pinion and the other mitre wheel
revolving on a cross shaft, the second bevel pinion being also in gear with the
large wheel, but these by means of clutch boxes may be thrown in and out of
gear; thus when the second pinion and large wheel axle are out of gear the
mitre wheels are in gear, and a more rapid revolution of the screw is effected.
By this means the motion, when cutting, may either be slow forward and
backwards when the double tools are used, in which case only the bevel
wheels come into gear, or if a single tool be employed the return motion when
not cutting may be made rapid by bringing the mitre wheels in gear. When
the rack is employed the interposition of a large toothed wheel and pinion is
necessary.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Elias Barlow and William Nathan Dack in the Great Seal
Patent Office on the 19th March 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ELIAS
BARLOW, of Patricroft, in the County of Lancaster, and WILLIAM NATHAN
DACK, of the same Place, Engineers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of September, in the year of our
Lord One thousand eight hundred and sixty-six, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,

page_text: the said Elias Barlow and William Nathan Dack, Her special license that
we, the said Elias Barlow and William Nathan Dack, our executors,
administrators, and assigns, or such others as we, the said Elias Barlow
and William Nathan Dack, our 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 "CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PLANING METALS,"
upon the condition (amongst others) that we, the said Elias Barlow and
William Nathan Dack, our executors or administrators, by an instrument in
writing under our, or one of our 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Elias Barlow, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement and accompanying Drawings (that is to say) :-
The Invention relates to that portion of the machinery employed in planing
metals known as the tool and tool box, and consists, first, in the adaptation
and use of two tools or cutters to each down slide employed in the machine
instead of employing one tool as hitherto, the object being to effect the forward
cut with one tool, and also to cut backwards on the return of the table with
the other; for this purpose the cutters are set or arranged in a separate tool
box side by side, or back to back, and are made adjustable both vertically and
laterally either by mounting the boxes or slides to move both ways, or the
tool may be mounted in one vertical slide which is moved upwards or downwards
by a screw, the lateral movement or angle being controlled and determined
by two set screws, each separate tool being fitted with such compound adjust-
ment. I would here remark that the double tools are equally applicable
whether they be used stationary whilst the table and metal under operation
is moved or the tools be traversed and the table be stationary.
A second part of the Invention relates to an improved arrangement of
gearing for effecting a variable traverse of the table or of the tools, and is
equally applicable either to the screw or rack and pinion motion, are well-
known means of effecting the traverse of the table and tools. This novel
arrangement of gearing consists of a large bevil wheel, two bevil pinions, and

page_text: gear
a pair of mitre wheels, the larger bevil wheel and one mitre being secured
to the end of the screw shaft moving the table; into the larger bevil wheel
the driving pinion gears, the other bevil pinion and the other mitre wheel
revolving on a cross shaft, the second bevil pinion being also in gear with the
large wheel, but these by means of clutch boxes may be thrown in and out of
gear; thus when the second pinion and larger wheel axle out of the mitre
wheels are in gear and a more rapid revolution of the screw is effected. By
this means the motion, when cutting, may either be slow forward and
backwards when the double tools are used, in which case only. the bevils
come into gear, or if a single tool be employed the return motion, when not

rack is employed the interposition of a large toothed wheel and pinion is
necessary.
In order that the Invention may be better understood and explained in
detail we have hereunto attached a Sheet of Drawings made upon a scale of
about three inches to the foot, similar letters of reference being marked upon
corresponding parts of the apparatus.
Fig. 1 represents a transverse section of the improved double tool box
which may be employed. for cutting, both with the forward and backward
traverse of the planing machine table, or the tools may be so arranged as to
give with the forward motion a rough cut, or they may be arranged so that
the leading or front tool will take a rough cut and the second or following
tool on returning a finishing cut, the planing machine table in the two latter
instances having a similar motion going and returning; Fig. 2 represents a plan
view of the same, shewn in section taken through the lines A, B, C, D.
Fig. 3 represents another arrangement or modification of the double tool
box in which a framework is employed for supporting the boxes, and in which
the front box is capable of being adjusted from the front; Fig. 4 represents
a plan view of the same, and Fig. 5 represents a back end view of the
planing machine, table, and bed having the improved arrangement of gearing
applied thereto for imparting a variable traverse to the table or to the uprights
and tools.
In Figs. 1, 2, 3, 4, and 5, a, a, is the cross bearing or slide supporting the
moveable bearings b, b¹, to which the tool boxes c, c³, are secured, being well-
known parts of the planing machine; the tool box c in Figs. 1 and 2 is
hinged or supported in the framing d secured to the vertical slide b¹, by
means of the centre or supporting studs 62, 63, the front of the box or framing d
being constructed in the form of a bed or slide upon which the frame of the
front tool box c' is supported and caused to slide for adjustment by means of

page_text: the screw e, the tools being firmly secured in their respective boxes by means
of the set screws f, f, the tools being placed back to back. The double tool
box, as seen in Figs. 3 and 4, in which the tools are arranged face to face is
supported in the framing g, secured to the vertical slide 6'; by this arrangement
the front tool box is adjusted from the front by means of the screw h, and the
tools are secured in their respective boxes by means of the inclined wedge
bars i and screws it, the lateral position of the front tool in the box c¹ being
adjusted by means of set screws placed one on each side of the tool. In
order that it can have a separate lateral adjustment independant from the
tool in the box c'. In Fig. 5, 1, 1, are the uprights; m, the table, and n
the bed of an ordinary planing machine, the driving bevil wheel o keyed on to
the end of the screw which drives the table m is supplied with two series of
teeth, one set o¹ forming a mitre bevil wheel of small diameter, and the outer
set o forming a bevil wheel of large size; these wheels are driven in the
ordinary manner by strap and pulley p through the medium of the following
arrangement of gearing:-The pulley p is keyed on to the cross driving shaft 9
which is also supplied with two bevil pinions r, r, and one mitre wheels,
which are governed by the clutch boxes t, t¹, through the medium of the
handle and connecting rod v, so as to drive the table m in the following
manner: If the cut to be made by the tool is required to be made both ways,
that is, with the forward and backward traverse of the table, the clutch t is
placed in gear, by which means it becomes the driver of the bevil pinion r
and r, which give the required to-and-fro traverse to the table through the
medium of the large bevil o keyed on the end of the driving screw or driven
through the medium of the carrier wheels w, w. If a quick return motion is
required the handle and connecting rod is acted upon so as to put the clutch t¹
into gear with the mitre wheels, and at the same time the clutch is placed
out of gear, by this means the mitre wheels becomes the driver, and as the
clutches are placed in or out of gear the quick or slow return motion of the
table are readily effected.
Having now described the nature of the said Invention, together with the
method of carrying the same into practical effect, we wish it to be distinctly
understood that we claim,-
The novel arrangement, construction, and application of double tool boxes
to be employed in apparatus for planing metals, wherein the cutting tools are
made capable of being separately and independantly adjusted, so that one tool
may effect the forward rough cut, and as the table returns the second tool
effects the finishing cut, or the tools may be arranged to perform a single or
double cut in any manner desired.

page_text: Secondly, we claim the employment and use of the variable or change
gearing in order to effect a quick or slow movement of the table required,
as herein-before described, set forth, and fully illustrated in the Drawings
attached.
In witness whereof, I, the said Elias Barlow, have hereunto set my
hand and seal, this Eighteenth day of March, in the year of our Lord
One thousand eight hundred and sixty-seven.
ELIAS BARLOW. (L.S.)
