IMPROVEMENTS IN MACHINERY OR APPARATUS FOR WASHING WOOL AND OTHER FIBROUS MATERIALS
Year: 1863

page_text: LETTERS PATENT to John Petrie, of Rochdale, in the County of Lancaster,
Machine Maker, for the Invention of "IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR WASHING WOOL AND OTHER FIBROUS MATERIALS."
Sealed the 4th December 1863, and dated the 8th June 1863.
PROVISIONAL SPECIFICATION left by the said John Petrie at the
Office of the Commissioners of Patents, with his Petition, on the 8th
June 1863.
I, JOHN PETRIE, of Rochdale, in the County of Lancaster, Machine
Maker, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR WASHING WOOL AND OTHER FIBBOUS
MATERIALS," to be as follows:-
My Invention relates to that construction of machine for washing for
which Letters Patent were granted to John Petrie, junior, and Samuel
Taylor, bearing date 11th Jany. 1853, No. 75, and consists in a method of
driving the endless apron. For this purpose I provide the said apron with a
series of teeth or projections, in gear with which is a toothed roller situate
between the two end rollers, and these end rollers therefore I can use of a
smaller diameter than would be necessary if they were the drivers.
The above-mentioned toothed roller may be in gear with the apron on the
upper and lower sides thereof, or on one side only.

filed by the said John Petrie in the Great Seal Patent Office on the

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN PETRIE,
junior, of Rochdale, in the County of Lancaster, Ironmonger, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of June, One thousand eight hundred
and sixty-three, in the twenty-seventh year of Her reign, did, for Herself,
Her heirs and successors, give and grant unto me, the said John Petrie,
junior, Her special license that I, the said John Petrie, junior, my
executors, administrators, and assigns, or such others as I, the said John
Petrie, junior, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR WASHING WOOL AND OTHER
FIBROUS MATERIALS," upon the condition, amongst others, that I, the said
John Petrie, junior, by an instrument in writing under my hand and seal,
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same
to be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letter Patent.
NOW KNOW YE, that I, the said John Petrie, junior, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement and accompanying Drawings (that is to say) :-
My Invention relates to that construction of machine for washing for which
Letters Patent were granted to John Petrie, junior, and Samuel Taylor,
bearing date the Eleventh January One thousand eight hundred and fifty-three,
No. 75, and consists in a method of driving the endless apron. For this
purpose I provide the said apron with a series of teeth or projections, in gear
with which is a toothed roller situate between the two end rollers, and these
end rollers therefore I can use of a smaller diameter than would be necessary
if they were the drivers.
The above-mentioned toothed roller may be in gear with the apron on the
upper and lower sides thereof or on one side only. Figs. 1, 2, 3, 4, 5, exhibit
the improvement in several views. At Fig. 1 are o two rollers over which the

page_text: feed apron passes. The method adopted in constructing this feed apron is
shewn in plan and edge views at Figs. 2 and 3. It consists of a series of
bars p placed side by side and united together by links q. Upon the under
side of the bars p and at the middle thereof are attached a series of studs r
taking into recesses formed in a central roller s carried by a shaft t, which
shaft is also provided at each end with a roller u, serving as guides for keeping
the feed apron in its proper course, as shewn in the section Fig. 4; one of the
rollers o is shewn detached at Fig. 5, it is formed with a recess v, which recess
is for the purpose of allowing the studs r to pass. Motion is commenced
by any ordinary means to the rollers, which therefore drives the feed apron at
the central portion thereof, the object of which is as follows:-These feed
aprons are used for the purpose of delivering the material to rollers, and it is
therefore desirable to get the point x as near to those rollers as possible. Now
a certain diameter of the driving wheel is necessary in order to put the apron
in motion, but for the aforesaid reason the rollers o are required to be as small
as possible, this condition depriving them of their driving power, and for that
reason I give motion to the feed apron at some place between the end rollers
and where a roller of larger diameter may be employed.
Having thus described and ascertained the nature of my said Invention,
and the manner of carrying the same into effect, I desire it to be understood
that I claim, as secured to me under the above in part recited Letters Patent,
giving motion to the feed apron of such machines as aforesaid at a point
between the end rollers.
In witness whereof, I, the said John Petrie, junior, have hereunto set
my hand and seal, this Seventh day of December, in the year of our
Lord One thousand eight hundred and sixty-three.
JOHN PETRIE, Jr. (L.s.)
