A MACHINE OR IMPROVED MODE, BY USE OF MACHINERY, FOR FORMING AND MANU- FACTURING TUBES OR RODS, AND FOR OTHER PURPOSES
Year: 1828

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
BREIDENBACHI, of Birmingham, in the County of Warwick, Merchant, send
greeting.
WHEREAS I, the said Thomas Breidenbach, did, by my Petition, humbly
represent unto His most Excellent Majesty King George the Fourth, that
I had, after much labor, study, and expence, found out and invented "A
MACHINE OR IMPROVED MODE, BY USE OF MACHINERY, FOR FORMING AND MANU-
FACTURING TUBES OR RODS, AND FOR OTHER PURPOSES," which Invention I
believed would be of much benefit and utility, that I was the first and true
inventor thereof, and that the same had never been made or used by any
other person or persons, to the best of my knowledge or belief; and I most
humbly prayed His Majesty would be graciously pleased to grant unto me,
my exors, admors, and assigns, His Royal Letters Patent under His Great
Seal of Great Britain, for the sole working, using, and exercising and selling
of my
said Invention, and for all other benefit and advantage thereof, within
England and Wales and the Town of Berwick-upon-Tweed, for the term of
fourteen year, according to the Statute in that case made and provided: and
His said Majesty being willing to give encouragement to all arts and inven-
tions that might be for the public good, was graciously pleased to condescend
to my request, and therefore by His Royal Letters Patent under the Great
Seal of Great Britain, bearing date at Westminster, the Twenty-sixth day of
April, in the ninth year of His reign, of His especial grace, certain know-
ledge and mere motion, did, for Himself, His heirs and successors, give and
grant unto me, the said Thomas Breidenbach, my exors, admors, and assigns,
His especial licence, full power, sole privilege and authority, that I, the said
Thomas Breidenbach, my exors, adiñiors, and assigns, and every of them, by

page_text: myself and themselves, or by mine and our deputy or deputies, servants or
agents, or such others as I, the said Thomas Breidenbach, my exors, adñiors,
or assigns, should at any time agree with, and no others, from time to time
and at all times hereafter during the term of years therein expressed, should
and lawfully might make, use, exercise, and vend my said Invention within
that part of His said Majesty's United Kingdom of Great Britain and
Ireland called England, His Dominion of Wales, and Town of Berwick-
upon-Tweed, in such manner as to me, the said Thomas Breidenbach, my
exors, adññors, and assigns, or any of us, should in mine or our discretion
scem meet; and that I, the said Thomas Breidenbach, my exors, adíñors,
and assigns, should and lawfully might have and enjoy the whole profit,
benefit, commodity, and advantage, from time to time coming, growing,
accruing, and arising, by reason of the said Invention, for and during the
term of years therein mentioned, to have, hold, exercise, and enjoy the said
licence, powers, privileges, and advantages therein-before granted or men-
tioned to be granted unto me, the said Thomas Breidenbach, my exors,
admors, and assigns, for and during and unto the full end and term of four-
teen years from the date of these said Presents next and immediately ensuing,
and fully to be complete and ended, according to the Statute in such case
made and provided; in which said Letters Patent is contained a proviso
that if I, the said Thomas Breidenbach, should not particularly describe
and ascertain the nature of my said Invention, and in what manner the
same is to be performed, by an instrument in writing under my hand and
seal, and cause the same to be enrolled in His said Majesty's High Court
of Chancery within four calendar months next and immediately after the
date of the said Letters Patent, that then the said Letters Patent, and all
liberties and advantages whatsoever thereby granted, should utterly cease,
determine, and become void, anything therein-before contained to the contrary
thereof in anywise notwithstanding, as in and by the said Letters Patent,
relation being thereunto had, may more fully and at large appear.
NOW KNOW YE, that I, the said Thomas Breidenbach, in compliance
with the said proviso, do hereby describe and declare that my said Inven-
tion of A Machine or Improved Mode, by Use of Machinery, for Forming
and Manufacturing Tubes or Rods, and for other Purposes, consists in using
what I call two blocks, made either of metal or metals, or of any other hard
substance, made to slide one upon the other, which mode or principle of
sliding I employ for making or forming taper tubes or rods, whether round or
of any other shape, form, or forms, and for other purposes, and which I now
describe by the Drawing or Plan above set forth.
Figure 1 represents the whole machine when closed. A is what I call

page_text: the undermost block, which is fastened and secured to a bench by screws, or
in any other way. B is what I call the uppermost or sliding block, which is
bevelled on the sides, as shewn by front, Figure 5, and slides under what I
call dovetailed bars, indicated by C, Figures 1 and 5, which bars are longi-
tudinally affixed to block A on its edges, and prevent block B moving in any
direction except in a straight line. And the way in which I proceed to
operate is this: In each of the blocks I groove, sink, or cut half of the
pattern or model of any intended article, so that when the blocks are brought
together, as at Figure 1, they form the whole; I then have what is called a
mandril to fit and correspond with the shape or form of my said pattern or
model. Thus, for instance, to make or form a taper tube I make a groove
of that shape, of half the diameter of such tube, in each of the blocks, see
Figure 2 of Drawing, which represents the undermost block with a groove
(D), as before stated. Upon this block I place a sheet of metal, shaped for
the purpose (see Figure 3), which I press or force into the groove by means
of the mandril, Figure 4, made either of metal or metals, or any other hard
substance, and drawing or sliding over this mandril the uppermost block from
point to point until both blocks do close, as at Figure 1; the tube is then
formed, and I afterwards finish it in the usual way as other tubes are. I
have, however, to remark, that I need not always groove, sink, or cut my
patterns or models into the blocks themselves, as I may equally use loose
tools or dies, according as may best suit my purpose, which I can affix upon
the aforesaid blocks, using these merely to accomplish the work by the
sliding, which principle is what I consider and call an improved mode by use
of machinery for forming and manufacturing tubes or rods, and for other
Durposes.as aforesaid.
