CERTAIN IMPROVEMENTS IN MACHINERY, TOOLS, OR APPARATUS POR TURNING, BORING, AND CUTTING METALS AND OTHER SUBSTANCES
Year: 1844

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
FULLER (of the firm of William Collier and Company), 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, and sealed at West-
minster, the Twenty-ninth day of October, in the eighth year of the reign
of Her said Majesty, did, for Herself and successors, give and grant unto
me, the said Thomas Fuller, Her especial licence, that I, the said Thomas
Fuller, my executors, administrators, and assigns, or such others as I, the
said Thomas Fuller, my executors, administrators, and assigns, should at any
time 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 and Wales and the Town of Berwick-upon-Tweed,
my Invention of "CERTAIN IMPROVEMENTS IN MACHINERY, TOOLS, OR APPARATUS
POR TURNING, BORING, AND CUTTING METALS AND OTHER SUBSTANCES;" in which
said Letters Patent is contained a proviso that I, the said Thomas Fuller,
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
Thomas Fuller, do hereby declare that the nature of my said Invention, and

page_text: the manner in which the same is to be performed, is particularly described and
ascertained in and by the Drawings hereunto annexed, and the following
explanation thereof, that is to say:-
My Improvements in Machinery, Tools, or Apparatus for Turning, Boring,
and Cutting Metals and other Substances, consist in the novel and peculiar
arrangement or construction of mechanism designed to perform the several
operations of turning, boring, sliding, screw-cutting, and wheel-cutting (as
required), in one engine, tool, or machine. Such being the nature and object
of my said. Invention, I shall proceed to shew the manner in which the same
is to be performed; and as the principal claim to novelty or improvement
consists in the entire arrangement and combination of the machinery rather
than in any of its details, I have attached to these Presents a Drawing suffi-
cient to illustrate my Invention, and to render the same perfectly intelligible
to the practical engineer, being drawn upon a scale of about one inch and a
half to the foot.
Figure 1 is an end elevation of the machine, exhibiting the general
arrangement of the tool for turning, boring, sliding, screw-cutting, and wheel-
cutting. Figure 2 is a side elevation of the machine; and Figure 3 is a plan
or horizontal view of the same, as seen from above, and which Figure most
perfectly illustrates the entire arrangement of the machine. A is the head
for wheel-cutting; B, the spindle or turning headstock; C, the lathe bed with
its carriage and loose headstock; D, the driving connection between the
spindle and regulator screw; E, the connection between the handle shaft and
the regulator wheel F, for dividing when cutting the teeth of wheels; and G
is the cutter for metal, which may be driven in any convenient manner.
Figures 7 and 8 are two detached views of the spindle and cutter for cutting
wood, wheel-patterns, or cogs, and when used are to be put in the place of the
cutter and spindle G. Figures 4, 5, and 6, represent in three different views
a particular arrangement of mechanism for moving the tool carriage by
means of a screw, when used for screw-cutting and sliding and turning trans-
verse surfaces, but in the latter cases using the screw simply in the character
of a shaft, and in such a way that the threads of the screw are preserved in
perfect condition to be used exclusively for screw-cutting. a is the regulator
screw, with a groove 6 extending the whole length of its thread. c is a worm,
with its key fitting and sliding in the groove b, the worm over-riding the
the threads of the screw and working in the wheel d, which drives the mitre
wheels e, e; they again, through the shaft f, driving the spur wheels g and the
pinion h, which working in the rack i moves the carriage for "sliding." When
employed for "surfacing," the worm c gives motion (same as just described)
b

page_text: to the mitre wheels e, e, but the shaft f is pushed endways; and while the
spur pinion g is thus put out of gear, the spur wheel j is brought into gear
with the pinion k. This pinion is on the end of the screw l, which moves the
slide for tranverse surfacing. When used for "screw-cutting," the spur
wheel and the mitre wheel e are brought out of gear, and the clasp nut n
closed. The spur pinion g remains in gear so as to be ready for use in
running back the carriage by means of a handle on the end of the shaft f, which
acts upon the rack through the medium of the wheels g, g, h. The advantage
of the worm c resting upon the lugs m, m, is, that it forms a support or
bearing to the screw without coming in contact with or any way injuring its
threads, and keeping the screw at the same time always parallel with the
line of centres and central with the clasp nut n, n.
Having now described the nature of my said Invention, and the manner in
which the same is to be performed, I desire it to be understood that I claim
as my Invention the novel and particular arrangement, combination, or con-
struction of mechanism or apparatus designed for the purposes of turning,
boring, sliding, screw-cutting, and wheel-cutting, in one engine, machine, or
tool, as exhibited in Figures 1, 2, and 3, in the Drawing, and particularly the
detailed arrangement shewn in Figures 4, 5, and 6, of the worm cover-
riding the regulator screw a, in the manner and for the purpose above de-
scribed, whether in connection with the wheel-cutting apparatus or otherwise.
In witness whereof, I, the said Thomas Fuller, have hereunto set my
hand and, this Twenty-eighth day of April, in the year of our Lord
One thousand eight hundred and forty-five.
