Year: 1828

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
SLATER, of Birmingham, in the County of Warwick, Manufacturer of Coach
Springs and Axletrees, send greeting.
WHEREAS I, the said John Slater, did by my petition humbly represent
unto His most Excellent Majesty King George the Fourth, that I had
invented "CERTAIN IMPROVEMENTS ON AXLETREES AND THE BOXES FOR CARRIAGE
WHEELS," that I was the first and true Inventor thereof, and that the same
had never been practised by any other person or persons whomsoever to my
knowledge or belief; and I most humbly prayed His Majesty that He would
be graciously pleased to grant unto me, my exors, admors, and assigns, His
Royal Letters Patent under His Great Seal of His United Kingdom for the
sole usc, benefit, and advantage of my said Invention within England, Wales,
and the Town of Berwick-upon-Tweed, for the term of fourteen years,
pursuant to the Statute in that case made and provided; His said Majesty
being willing to give encouragement to all arts and Inventions which might
be for the public good, was graciously pleased to condescend to my request,
and therefore His said Majesty, by His especial grace, certain knowledge,
and mere motion, by His Royal Letters Patent under the Great Seal of Great
Britain, bearing date at Westminster, the Fifteenth day of December, in the
ninth year of His reign, did, for Himself, His heirs and successors, give and
grant unto me, the said John Slater, my exors, admors, and assigns, His
especial licence, full power, sole privilege, that I, the said John Slater, my
exors, admors, and assigns, and every of them, by myself and themselves, and
by mine and our deputy or deputies, servants or agents, or. such others as I,
the said John Slater, my exors, adñors, or assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during

page_text: the term of years therein expressed, should and lawfully might make, use,
exercise, and vend my said Invention within that part of His 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
John Slater, my exors, adñiors, and assigns, or any of us, should in mine or
our discretions seem meet, and that the said John Slater, my exors, admors,
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 mentioned to be
granted unto me, the said John Slater, my exors, admors, and assigns, for and
during and until the full end and term of fourteen years from the date of the
said Letters Patent 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 John Slater,
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 six 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, will more fully and at
large appear.
NOW KNOW YE, that I, the said John Slater, in compliance with the
said proviso, do hereby declare that the nature of my said Invention, and the
manner in which the same is to be performed, is particularly described and
ascertained by the Drawing hereunto annexed, and by the following description
thereof, that is to say:-
The nature of my Invention and improvements in making axletrees and the
boxes for carriage wheels consists in making the axletrees in the usual forms
but in the following manner:-I make a large sized hole or hollow into the
end inside of the axletree arm, and at or near to the bottom or lower part of
the said hole I make a small hole or holes into the side or wearing part
of the axletree arm, which hole or holes are made to join and communicate
with the large end hole inside the said arm, and the small holes are made
opposite and fronting to the recess for the oil chambers in the boxes of the

page_text: axletree for introducing oil to the inside; and each box I first make in two
or more separate parts, the outside of wrought iron and the inside of brass
or any other metal or metals, with a recess or recesses, or oil chamber or
chambers inside or between the two metals. The outward part or covering
of the axletree boxes I make of wrought iron, which iron is fitted on the
outside of the brass or other metal box, and is sunk upon it while hot, and
both the outward and inward parts of the boxes are more secured together
with screws or rivets for making the boxes firm, which axletrees and boxes
I make with or without hole or holes in either of them or the oil chambers
or recesses. And for the convenience of supplying the axletrees and boxes with
oil, there are recesses or grooves inside the boxes; and for my convenience
I make the axletrees and boxes without any hole or holes, or oil reservoir to
either of them; and I make the inward parts of the boxes of brass or any
other metal or metals, and the outside of the boxes I make of wrought iron,
and secure the boxes to the axletrees in the usual manner either with short
screws or long screws, bolts, or screws only, as most convenient, the axletrees
and boxes being so contrived that any of the most approved principles may be
applied for holding and securing the boxes and wheels firm to the axletrees.
The Drawing herewith is made for better elucidating and explaining my
improved Invention of making the axletrees and boxes.
In witness whereof, I, the said John Slater, have hereunto set my hand
and seal, the Sixteenth day of May, in the tenth year of the reign of
His said most Excellent Majesty, and in the year of our Lord One
thousand oight hundred and twenty nine
AND BE IT REMEMBERED, that on the Sixteenth day of May, in the

all and every thing therein contained and specified, in form above written.
