page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSIAH
PUMPHREY, of New Town Row, Birmingham, in the County of Warwick,
Brass Founder, send grecting..
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 Second day of November, in the fourth year of Her reign, did;
for Herself, Her heirs and successors, give and grant unto me, the said Josiah
Pumphrey, Her especial licence, full power, sole privilege and authority, that
I, the said Josiah Pumphrey, my exors, admors, and assigns, or such others as
I, the said Josiah Pumphrey, my exors, admors, or assigns, should at any
time agree with, and no others, from time to time and at all times thereafter
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
TO BE EMPLOYED IN THE MANUFACTURE OF WIRE HOOKS AND EYES;" in which said
Letters Patent is contained a proviso that I, the said Josiah Pumphrey,
shall cause a particular description of the nature of my said Invention, and
in what manner the same is to be performed, to be inrolled in Her said
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
annear

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Josiah Pumphrey, do hereby declare that the nature of my said Invention,
and the manner in which the same is to be performed, are fully described
and ascertained in and by the following statement thereof, and the Drawings
hereunto annexed, that is to say:-
Instead of the ordinary mode of flattening and polishing. (commonly called
planishing) wire hooks and eyes, I employ for those purposes the machinery
herein-after described, and as represented in the annexed Drawings. This
machinery consists of two dies, one of which is firmly imbedded in the
machine, and the other is fixed to a bolt or ram working in guides, and is
made alternately to approach and recede from the before-mentioned fixed
die by the revolution of an eccentric wheel or cam mounted on an hori-
zontal axis, which is actuated by steam or other adequate power. The
partially formed hooks and eyes or other articles are introduced upon the
lower or fixed die, and 'the descent of the upper die thereon effects
the flattening and planishing of the hook and eye or other article.
In
order.to
.
o render quite intelligible, the details; of my improved machinery,
I will now describe the same more particularly, with reference to the accom-
panying Drawings.
Figure 1 exhibits an external elevation of my improved machinery, and
Figure 2 a side view (partially in section) of the same. Ata.is the shaft,
carrying the fly wheel b. At c is an eccentric wheel, mounted, on the
shaft, surrounded with a clip d. e, e, are links connecting the eccentric ring
or clip with, the radius rod f. At g is a joint pin, on which the eccentric
clip vibrates, and, to which the radius rod is attached... This pin and radius
is shewn in a separate Figure 3. At h is a forked lever, connecting the
adjusting pin i of the ram or bolt j with the radius rod, which bolt works in
guides k, k. 7 is the upper die affixed to the bolt, and m, the lower die
attached to the bed o by the cotter p. At q is a bracket to support the radius
rod; and at r, r, is an adjusting screw and lock nut, by which the distance
between the two dies may be accurately adjusted. At s is the driving pulley;
t, the driving plate; u, the lever for throwing the pulley in and out of gear;
and 1, v, represents the framing of the apparatus.
Having now described the nature of my Invention, and the manner in
which I carry the same into effect, I desire it to be distinctly understood. that
I do not claim any of the parts described when used for any other purpose
than those herein-before mentioned. But I do claim as of my Invention the
application or employment of the machinery described in the flattening and
planishing of wire hooks and eyes and other articles.
