Year: 1839

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
MASON, of Rochdale, in the County of Lancaster, Machine Maker, 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 Fifteenth day of August, in the third year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said John
Mason, Her especial license, full power, sole privilege and authority, that I,
the said John Mason, my executors, administrators, and assigns, and such
others as I, the said John Mason, my executors, administrators, and assigns,
should agree with, and no other, 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, Wales, and the Town of Berwick-upon-
Tweed, my Invention of " CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS
FOR BOBING AND TURNING METALS AND OTHER SUBSTANCES;" in which Letters
Patent is contained a proviso, that I, the said John Mason, shall cause
a particular description of the nature of my said Invention, and in what
manner the same is to be performed, to be enrolled 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
John Mason, do hereby declare that the nature of my said Invention, and the

page_text: manner in which the same is to be performed, is particularly described and
ascertained in and by the Drawings hereto annexed, and the following
explanation thereof, that is to say:
My improvements in machinery or apparatus for boring and turning metals
and other substances consist, firstly, in the application of a simple self-acting
apparatus to ordinary boring or turning lathes, or other boring or drilling
machinery, for the purpose of throwing the strap off the fast or driving pulley
on to the loose pulley in the ordinary driving apparatus at the exact period of
time when the drill-boring bar or cutting tool has completed its operation;
that is, when the hole is completely cut through any substance, material, or
article to be bored, without the assistance or direction of any attendant, and
thereby economizing the labour, time, and number of workmen, as one boy
will be sufficient to attend several of such machines, the cutting tool being
prevented from advancing. Secondly, in the application of suitably-contrived
driving gearing to any small portable hand-boring or drilling apparatus, in
order to effect the advance of the cutting tool simultaneously with its rotary
action. And, thirdly, in a simple addition to the holding nogs of the chuck or
face plate, used in ordinary turning lathes in order to prevent the cuttings of
metal falling into the body of the chuck, and choking or wearing the interior
working parts of the same. But in order that my improvements may be per-
fectly understood, and their application more fully explained, I have attached
to these Presents a Sheet of Drawings, and marked the same with figures and
letters of reference.
Figure 1 represents a front elevation, and Figure 2 a plan or horizontal
view of the fast headstock of an ordinary boring or turning lathe, to which
the first part of my improvements are shewn attached, being those parts
shaded with color. The common parts are drawn in outline only. The
headstock of the lathe is shewn at a, a; the speed or cone pulleys at b, b;
the spindle at c, c; and the chuck or face plate at d, d. The drill-boring bar
or cutting tool is represented at e, being made to advance to its work by by
means of the ordinary forcing apparatus in connection with the following
headstock or poppet head as usual. The piece of metal to be bored is repre-
sented by the dotted lines f. f, and it will be perceived that there is a small
horizontal rod g, g, extending through the centre of the lathe spindle; at the
reverse end of this rod g is a collar h screwed tightly upon it, and bearing
against the tail piece i, i. The end of this tail piece is provided with an
inclined plane upon which the foot of the upright rod k, k, bears. This
upright rod is supported and slides in a small pillar 1, 1, affixed to the bed of
the lathe, and the upper end of the rod k is to be connected by any suitable

page_text: leverage to the forked strap rod which is to shift the strap from the fast to
the loose pulley in the driving apparatus above. Now, it will be very readily
perceived that the instant the boring or drilling tool e has cut the hole entirely
through the piece f, the advancing point of the tool will bear against the end
of the rod g, and by shifting it horizontally about one quarter of an inch,
raise, by means of the inclined plane at the other end, the vertical strap rod k,
and thus immediately throw the driving strap from the fast or driving pulley
on to the loose pulley. It will of course be evident that when any hole or
aperture is not intended to be cut entirely through the article in the lathe,
then the pillar with its vertical strap rod must be fixed upon the poppet head
or following headstock, and the strap rod shifted by any adjustable stops
placed upon the advancing screw cylinder of the forcing apparatus. It will
also be evident to any practical mechanic that the same contrivance is equally
applicable to any vertical, horizontal, or other drilling or boring apparatus, as
I have only shewn its application to a lathe by way of illustration.
The second part of my improvements is represented in Figure 3, which is a
side elevation, and Figure 4, which is a plan view of a portable hand boring or
drilling apparatus. The improvement in this apparatus consists simply in the
application of a driving pinion a and two driving wheels b and c, the upper
wheel having one more tooth in its periphery than the lower one, and the
pinion gearing with both, the effect of which is, that by turning the winch
handle d, and thus driving the pinion a round the periphery of the spur
wheels, the wheel 6 having, say 70 teeth, and being fast upon the screw e, and
the wheel c having, say 69 teeth, and loose upon the screw, but held only by
the pin f, the quick rotary action of the cutter is obtained simultaneously
with the slow advancing motion of the screw with the cutting tool through its
work, by the single operation of turning the winch handle.
The third part of my improvement is shewn in Figure 5, which represents
a front view of a chuck or face plate of a lathe a, a, a, the three holding
nogs or dies b, b, b, sliding in the mortices c, c, c, by any well-known contri-
vance; my improvement being the elongation or tail piece d, d, d, of the
holding nogs, and increasing the number of holding points, so that the open
mortices for the slides shall always be covered, and consequently the cuttings
of metal, &c., prevented from entering or choking the interior working parts
of the chuck or face plate.
In witness whereof, I, the said John Mason, have hereunto set my hand
and seal, this Fourteenth day of February, in the year of our Lord One
thousand eight hundred and forty.
JOHN (L.S.) MASON.

page_text: AND BE IT REMEMBERED, that on the Fourteenth day of February, in
the third year of the reign of Her Majesty Queen Victoria, the said John
Mason came before our said Lady the Queen in Her Chancery, and acknow-
ledged the instrument aforesaid, and all and every thing therein contained and
specified, in form above written. And also the instrument aforesaid was
stamped according to the tenor of the Statute made in the fifty-fifth year of
the reign of His late Majesty King George the Third.
