Year: 1872

page_text: LETTERS PATENT to John M Naught and William McNaught, the
younger, of St. George's Foundry, Rochdale, in the County of
Lancaster, Engineers and Machinists, for the Invention of "Im-
PROVEMENTS IN MACHINERY FOR SCOURING AND WASHING WOOL OR OTHER
FIBROUS SUBSTANCES."
Scaled the 18th March 1873, and dated the 16th October 1872.
PROVISIONAL SPECIFICATION left by the said John McNaught and
William McNaught at the Office of the Commissioners of Patents,
with their Petition, on the 16th October 1872.
We, JOHN MCNAUGHT and WILLIAM MCNAUGHT, the younger, of St.
George's Foundry, Rochdale, in the County of Lancaster, Engineers and
Machinists, do hereby declare the nature of the said Invention for "Im-
PROVEMENTS IN MACHINERY FOR SCOURING AND WASHING WOOL OR OTHER FIBROUS
SUBSTANCES," to be as follows:-
:―
Firstly. Our Invention consists of a new arrangement of well known
scouring and washing machines so that they may be used in rooms

page_text: smaller than those required by machines of ordinary arrangement. The
trough of the machine is made, to any required angle to suit the form of
the room in which it is to be worked, and may when required be turned
back so that one part of the trough will be parallel to the other part.
The ordinary swing rakes are employed to agitate and pass on the wool,
but the one just before the angle or bend is arranged to deliver towards
the side of the succeeding rake to a greater or less extent according to
the amount of angle in the bend. When the trough is bent so that the
two sides are parallel then one or more rakes are arranged to work
between and at a right angle to the parallel portions of the trough.
Secondly. Our improvements relate to the plate in which the curved
retaining prongs net in wool washing machines. The holes in the plate
for the prongs have been hitherto made countersunk or parallel to give
space for the curve of the prongs.
Our improvements consist in making the holes in a curve so that they

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John MoNaught and William McNaught in the
Great Seal Patent Office on the 15th April 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
MCNAUGHT and WILLIAM MCNAUGHT, the younger, of St. George's
Foundry, Rochdale, in the County of Lancaster, Engineers and
Machinists, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixteenth day of October, in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said John McNaught and William M.Naught,
the younger, Her special license that we, the said John MºNaught
and William McNaught, the younger, our executors, administrators,
and assigns, or such others as we, the said John M Naught and
William McNaught, the younger, our 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

page_text: 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 FOR SCOURING AND
WASHING WOOL OR OTHER FIBROUS SUBSTANCES," upon the condition (amongst
others) that we, the said John M°Naught and William M°Naught, the
younger, by an instrument in writing under our hands and seals (or
under the hand and seal of one of us), should particularly describe
and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the samo to be filed in the
Great Seal Patent Office within six calendar months next and immo-
diately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said John McNaught and William
McNaught, the younger, do hereby declare the nature of our said
Invention, and in what manner the same is to be performed, to bo
particularly described and ascertained in and by the following statement
and accompanying Drawings, that is to say:-
Firstly. Our Invention consists of a new arrangement and combination
of well known scouring and washing machines so that they may be used
more conveniently or in rooms smaller in length than those required by
machines of ordinary arrangement. The trough or troughs of the
machines are made to any required angle to suit the form of the room
or place in which the machine is to be worked, and such troughs may
when required be turned back so that one part of the trough or troughs
will be parallel to the other part. The ordinary swing rakes are employed
to agitate and pass on the wool, but the one just before the angle or
bend is arranged to deliver towards the side of the succeeding rake to a
greater or less extent according to the amount of angle in the bend.
When the trough or troughs is bent or arranged so that the two sides
are parallel, then one or more rakes are arranged and combined to work
between and at a right angle to the parallel portions of the trough or
troughs.
Secondly. Our improvements relate to the plate in which the curved
retaining prongs act in wool washing machines, which retaining prongs
serve to hold the wool on the incline when delivered by the rake that
lifts it from the trough. The holes in the plate for the prongs have been
hitherto made countersunk or parallel and larger than the diameter of
the prongs to give space for the curve of the prongs.

page_text: Our improvements consist in making the holes in a curve so that they
will accurately fit the curve retaining prongs all through the plate.
Fig. 1 is a side elevation partly in section, and Fig. 2 is a plan
shewing parts of a machine according to our improved arrangement,
having one bend and adapted to two sides of a room.
Figs. 3 and 4 are views corresponding respectively to Figs. 1 and 2,
but showing parts of a machine according to our improved arrangement,
having two bends and adapted for three sides of a room.
The separate parts are ordinary and well known, and the Drawings
illustrate our Invention by showing our improved arrangement and
combination of the trough, swing rakes, gearing, and other parts.
In Figs. 1 and 2 a are squeezing rollers belonging to a preceding
trough 5, or this end may be that at which the wool is first fed to the
machine. c is the swing rake that submerges the wool and delivers it
to a second rake c², placed at right angles as shewn, which passes the
wool on to the other succeeding rakes in the ordinary manner, and from
this trough (6) to the next, and so on, if and as required. In Figs. 3 and 4
the first rake (c') passes the wool on to the second (c³), third (³), and
fourth (e), working at right angles to the first (c), the fourth rake (c')
delivering to the fifth (c), working at a right angle to the fourth (c')
and parallel to the first rake (c',) the sixth rake (c) lifting the wool from
the trough (b) to be discharged or passed on to the next trough as
required.
Fig. 5 illustrates the second part of our Invention. d is the plate
through which the retaining prongs (e) pass, which prongs are carried
by a bar or frame e' centred at e³, and are consequently curved to a
radius struck from that centre. The prongs are accurately curved and
formed to the radius, and the holes for them are made in the plate d to
accurately fit the prong through the entire thickness of the plate. The
curved holes for the prongs may be formed if desired in bushes inserted
in the plate for the retaining prongs.
We have now particularly described the nature of our Invention and
the modes of carrying it into effect, and claim as our Invention.
Firstly. The arrangement of the troughs of washing machines as
described, and also the arrangement and combination of the washing

page_text: troughs and swing rakes substantially as herein-before described and
illustrated by the accompanying Drawings.
Secondly. The forming of the holes in the plates for the retaining
prongs substantially as herein-before described.
In witness whereof, I, the said John MºNaught, on my own behalf
and on behalf of the said William McNaught, the younger,
have hereunto set my hand and seal, this Tenth day of April,
in the year of our Lord One thousand eight hundred and seventy-
three.
