Year: 1840

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, NATHANIEL
BATIO, of Manchester, in the County of Lancaster, Engineer, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Twenty-fifth day of November, One thousand eight hundred and
forty, in the fourth year of Her reign, did for Herself, Her heirs and succes-
sors, give and grant unto me, the said Nathaniel Batho, Her especial licence,
full power, sole privilege and authority, that I, the said Nathaniel Batho,
my executors, administrators, and assigns, and such others as I, the said
Nathaniel Batho, my executors, administrators, and assigns should at any time
agree with, and no others, from time to time and at all times during the term
of years therein expressed, should and lawfully might make, use, exercise, and
vend, within England and Wales, and the Town of Berwick-upon-Tweed,
my Invention of "CERTAIN IMPROVEMENTS IN MACHINERY, TOOLS, OR APPARATUS
FOR PLANING, TURNING, BORING, OR CUTTING METALS AND OTHER SUBSTANCES;"
in which Letters Patent is contained a proviso, that I, the said Nathaniel
Batho, shall cause a particular description of the nature of my Invention, and
in what manner the same is to be performed, to be inrolled in. Her Majesty's
High Court of Chancery within six calendar months next and immediately
after the date of the said in part recited Letters Patent, as in and by the same,
reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Nathaniel Batho, do hereby declare that the nature of the said Invention, and

page_text: view; Fig. 6 a front view; and Fig. 7 an end view upon the under side of
the tool carriage a, a, is fixed a box-b, b; with two ears, which contain the
mút c; working upon the screw d; the screw d has spur wheel e cast upon
it, which gears into another spur wheel ƒättäched to the counter shaft g, upon
which an 'askew spur wheel gears into a corresponding askew wheel i fixed
upon the cross handle shaft ; thus the hand motion may be obtained by turn-
ing the cross handle, or power may be communicated by any convenient means,
or a simple variation in this motion may be made by substituting ordinary
bevilled wheels in the place of the askew wheels h and i. A further improve-
ment in the lathe consists of providing two tool boxes or carriers with slide
mótion's at the back and front of the carriage, order to cut screws or slide
backwards and forwards. A further improvement in lathes, and by which I
am enabled to convert an ordinary slide lathe into a slotting or morticing
machine, is exhibited in Sheet 2 of the Drawings, Fig. 1 being a front view,
Fig. 2 an end view, and Fig. 3 a plan, of the apparatus to be attached to the
following. headstock for this purpose. The following headstock is shewn at a, a,
in connection with which is the bevil wheel b, b, fixed upon the end of a shaft
c; and working underneath the barrel of the headstock; there is a bevil pinion
d working in thei bevil wheel b, and attached to the end of a' shaft e, upon
which are fixed the pulleys f, f, and a spur pinion g taking into another
spur pinion' h, keyed upon the end of the screw i, inside the following
Headstock, which answers for a fly wheel when used for turning purposes;
and when the machine is required for slotting purposes a face plate k is to be
fixed the other end of the shaft e, the bevel wheel 6 acting also as a face
plate: upon the reverse end; these face plates are provided with a dove-tailed
groove and slide, in which crank-pins ; are fixed being adjustable in the
grooves; to these pins are attached the connecting rods m, m, which being
connected at their other extremities to the Hollow spindle or barn; will impart
to it; a horizontal: reciprocating: motion, and thus it will be perceived that if this
bar carries a cutting. tool at its extremity, all the ordinary work of a slotting or
morticing machine may be performed. It must also be observed that the
spindle of the fast headstock should also be hollow, to receive the end' of the
cutting barn when the tool has completed it's cut, all of which improvements'
in the lathe I claim as my Invention!.
upon
-Thirdly, the screwing machine: My improvements in the machinery
commonly used, for screwing: bolts; &c, consist of a certain' apparatus contrived'
for nioving the cutting: dies to and from the bolt or work to be screwed; and is
also! shewn in the Sheet 1 of the Drawings, Fig: 8 being front view of the
apparatus; Fig. 9 an end view, and Fig. 10 a detached end view, of the dies

page_text: and die plate. The common bearing or parralleled carrying rods for supporting
the die plate is shewn at a, a, the die plate b, b, and the screwing dies at c, c.
Each of these dies is furnished with a dovetailed or square piece at the back,
and slides in a corresponding groove in the die plate; to each of the dies is
attached a right and left handed screw d and e, turning in their nut f, g, fast
upon the die plate. Now, it will be seen that by turning the cross handle h
at the end of the shaft i, i, which carries the pinions k, k, that these pinions
gearing into the pinions 1, 2, upon the ends of the screws d, e, will cause the
screws to be turned, and thus to open or close the dies as occasion may
require, which improvement I claim also as my Invention.
Fourthly, the drilling and boring machine. My improvements in the
drilling and boring machine is the general arrangement and construction of the
apparatus as far as is novel in application and effect, and consist principally of
the motion exhibited in Sheet 3 of the Drawings, for raising and lowering the
spindle with the drill or boring bar; Fig. 1 being a front view, Fig. 2 a side
view, and Fig. 3 a plan or top view, of the same. It will be seen that Fig. 1
is fitted with a boring bar and Fig. 2 with a drilling tool. Upon the driving
shaft a, a, is keyed a worm wheel 6, taking into a worm c upon the foot of the
upright shaft d, d; upon the upper end of this shaft a similar worm e gears
into a worm wheelf upon the stud or shaft g, upon the other end of which is
a pinion working in the rack i, i, attached to the spindle k, k, which 'motion
may be thrown in and out of gear as required, by means of the bevilled wheel Z
and pinion m at the lower end of the shaft d, which improvement I also claim
as my Invention.
Fifthly, the nut squaring and grooving apparatus. My improvements in
this apparatus consists of a simple piece of mechanism to be applied to the
single or compound slide rest of a lathe, and to be used in the lathe, the cutting
tool for shaping &c., to be fixed to the lathe spindle, and is exhibited in Sheet 4
of the Drawings. Fig. 1 is an elevation of the apparatus for turning or
squaring nuts; Figs. 2 and 3 are end elevations of the same. a, a, represents
part of an ordinary slide rest, upon which are screwed two sockets or standards
b, b, supporting the adjustable carriers c, c, in which the spindles d, d, are
mounted, for the purpose of holding the row of nuts e, e, e, e, to be trimed or
squared by the rotation of the cutting tool f, which is fixed upon the lathe
spindle; 9, g, is a holding box or clutch; and h, h, a dividing plate for setting s
the nuts. Figure 4 is a view of a slightly varied apparatus, in which the
spindle e is provided with various diameters of screwed arbors i, k, l, for holding
nuts of a large size. It will be observed by the plan view, Fig. 5, that two
cutting tools f, f, may be employed in order to turn either one or two sides of

page_text: the nuts at the same time. Fig. 6 is a plan view of a similar apparatus, but
modified for the purpose of. grooving screw taps, cutting key beds, &c. The
same letters indicate the corresponding parts of the other mechanism, the
cutting tool m being suitably formed for grooving a screw tap under operation
s such at n. This improved apparatus I also claim as my Invention.
In witness whereof, I, the said Nathaniel Batho, have hereunto set my
hand and seal, this Twenty-fourth day of May, in the year of our
Lord One thousand eight hundred and forty-one.
