Year: 1867

page_text: LETTERS PATENT to George Haseltine, of the "International Patent
Office," No. 8, Southampton Buildings, Chancery Lane, in the County
of Middlesex, Civil Engineer, for the Invention of "IMPROVEMENTS IN THE
MANUFACTURE OF PACKING FOR THE JOINTS OF STEAM ENGINES, PUMPS, AND
FOR OTHER PURPOSES."-A communication from abroad by Morris Botticher,
of Newark, New Jersey, United States of America.
Sealed the 24th April 1867, and dated the 5th March 1867.
COMPLETE SPECIFICATION filed by the said George Haseltine at the
Office of the Commissioners of Patents, with his Petition and Declaration,
on the 5th March 1867, pursuant to the 9th Section of the Patent
Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
II ASELTINE, of the "International Patent Office," No. 8, Southampton
Buildings, Chancery Lane, in the County of Middlesex, Civil Engineer, send
greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN THE
MANUFACTURE OF PACKING FOR THE JOINTS OF STEAM ENGINES, PUMPS, AND FOR OTHER
PURPOSES," and have petitioned Her Majesty to grant unto me, my executors,
administrators, and assigns, Her Royal Letters Patent for the same, and have
made solemn Declaration that it has been communicated to me from abroad
by Morris Botticher, of Newark, New Jersey, United States of America.

page_text: NOW KNOW YE, that I, the said George Haseltine, do hereby declare
that the following Complete Specification, under my hand and seal, fully
describes and ascertains the nature of the said Invention, and in what manner
the same is to be performed, in and by the following statement, reference
being had to the accompanying Sheet of Drawings making a part of this
Specification :-
Great difficulty has been experienced in keeping the stuffing boxes of steam
engines tight with the ordinary packing of cotton, hemp, and similar substances,
on account of its being so rapidly destroyed by the acton of the heat; two or
three days being sufficient to reduce it to powder where superheated steam is
used, the result being a waste of steam and considerable loss of time in
renewing the packing.
My Invention has for its object to overcome these objections, and consists
in a packing for stuffing boxes, expansion and other joints, composed of dry
powdered substances combined with fibrous material, which will withstand the
heat, and at the same time keep the boxes or joints perfectly tight, no oil or
other lubricating substance being required.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a longitudinal section through the centre of an ordinary stuffing
box, the piston rod being shewn in elevation; Figure 2 is a transverse section
Like letters refer to corresponding parts in each of the
through the same.
Figures.
:-
A represents an ordinary stuffing box; B, the piston or valve rod, and C
the chamber for containing the packing, which is made in the following
manner Dry pulverized soapstone and asbestos are first mixed together
in the proportion of about nine-tenths of the former to one-tenth of the latter,
and the compound thus produced is mixed with any suitable fibrous material,
such as cotton, hemp, or flax, the proportions of the soapstone and asbestos
may, however, be varied if desired. If a braided or plaited packing is to be
used the powder may be worked well into the fibrous material while it is being
manufactured into the required form, such as a "gasket" or rope; or the
fibrous material may be first plaited or braided and the dry powdered material
afterward worked into it. The stuffing box or joint is then filled tightly with
the packing above described, more of the powder being added, if found desirable,
when the box is being filled.
I do not confine myself to the use of soapstone and abestos as other dry
powdered substances may be used, such as plumbago or whiting, which will
be found to answer a good purpose.

page_text: The above-described packing possesses the following advantages:-
1st. Great durability, as it is not injured by heat or friction, and will retain
its flexibility, thus particularly adapting it for use where superheated steam is
used.
2nd. It requires no lubricating with oils, and will keep the boxes tight.
3rd. It can be furnished at a low cost.
The said improved packing, besides being applied to stuffing boxes, may be
used to advantage in axle or journal boxes, and a great saving in lubricating
material thereby effected.
Having thus fully described the said Invention, as communicated to me by
my foreign correspondent, and shown how the same may be conveniently and
advantageously carried into practise, I claim, a packing for stuffing boxes,
expansion and other joints, composed of dry powdered substances combined
with fibrous material, substantially as set forth.
In witness whereof, I, the said George Haseltine, have hereunto set my
hand and seal, this Fourth day of March, in the year of our Lord One
thousand eight hundred and sixty-seven.

communication from abroad by Morris Botticher, of Newark, New
Jersey, United States of America.
Dated the Fifth day of March, One thousand eight hundred and sixty-
seven (No. 613), the Complete Specification of which was filed by
the said George Haseltine at the Office of the Commissioners of
Patents, with his Petition and Declaration, on the said Fifth day of
March, pursuant to the 9th Section of the Patent Law Amendment
Act, 1852.
WHEREAS since the filing of the Complete Specification of the said Patent
ave discovered that the nature of my Invention is not ascertained and
cribed with sufficient precision, and that the claim is too broad and inde-
te, I am desirous of making and filing a Disclaimer and Memorandum of
eration herein-after contained.

page_text: NOW KNOW YE, THEREFORE, that I, the said George Haseltine, by
and with the leave of Her Majesty's Attorney-General, and for the reasons
aforesaid, do hereby disclaim, alter, and amend the said Specification by
striking out the word "If" commencing the sentence in line 29, page 2, of the
printed Specification, and the words "to be" after the word "is" in the same
line, and inserting the word twisted in said line after "braided," and the word
and after "used" in line 30 of the same page of the printed copy of the
Specification; and I amend and restrict the claim set forth in said Specifica-
tion by inserting the words braided, twisted, or plaited.before the word
"fibrous" in line 14, page 3, of the printed copy of said Specification.
And in order that the effect of the Disclaimer and Memorandum of Altera-
tion may be clearly understood I annex a copy of the Specification, as it will
appear after my said Disclaimer and Memorandum of Alteration have been
made.
