Wool or other Fibrous Materials.
WO JOHN PETRIE of Broomfield Rochdale in the County of Lancaster Machinist
and FREDERICK WILLIAM PETRIE of 34 William Street Rochdale in the County of
Tancaster, Machinist do hereby declare the nature of this invention to be as
follows:-
:-
Our Improvements relate to that portion of Machinery for Washing or Cleansing
Wool or other fibrous material by which the said wool or other fibrous material is
transferred from the Trough in which it has been washed or cleansed, to the Squeezing
Rollers and are made and based upon the mechanism for Washing or Cleansing Wool
or other fibrous material described in the Specifications of Letters Patent 43. A.D.
1874. and 4261 A.D. 1880.
Part of our Improvements relate to the method of conveying Wool or other fibrous
material, from the Trough in which it has been washed or cleansed, to the squeezing
ollers; when the Squeezing Rollers placed in proximity to the Trough have the
bottom roller placed below or partially below the level of the water line in the Trough,
but not submerged therein.
Our Improvements further relate to Machinery for Washing or Cleansing wool or
other fibrous material, when the Squeezing Rollers are placed above, or proximately
above the level of the water line in the trough in which the Wool or other fibrous
material is being washed or cleansed, and where Slide Bars or other ordinary
travelling appliances are used for conveying the Wool or other fibrous material to the
Squeezing Rollers.
In the specification of Letters Patent numbered 43. A.D. 1874 a fixed grid or
strainer, carried at one end by a support (fig. 4) is placed above the level of the
Water line in the trough, upon which grid the material is deposited by an ordinary
Rake or other such apparatus, the said material being then transferred to the
Squeezing Rollers by a vibrating Rake or other conveying Apparatus, the bottom
squeezing roller being below or partially below the level of the Water line in the
Washing Trough."

page_text: Our Improvement dispenses with the fixed grid and its support, and also of the
vibrating Rake or other conveying apparatus as therein described-In place thereof
we use a vibrating frame with teeth or prongs, which by its action conveys the
Wool or other fibrous material direct to the squeezing rollers. In the Letters
Patent numbered 4261 A.D. 1880. where the squeezing rollers are placed above or
proximately above the Water line in the Washing Trough a double headed or
ordinary vibrating Rake (fig. 9) is shewn by which the wool or other fibrous
material is transferred on to the Slide Bars or other travelling appliances used for
conveying the Wool or other fibrous material from the washing Trough to the
squeezing rollers. By our Improvements we dispense with the double headed
vibrating Rake and substitute therefor a single adjustable vibrating rake held by
a jointed radial rod and having a check or stop motion at the point of delivery,
so that by its action, the wool or other fibrous material is more effectually delivered
on to the Slide Bars or other travelling appliance used for conveying the wool or
other fibrous material to the Squeezing Rollers.

Wool or other Fibrous Materials.
We JOHN PETRIE of Broomfield Rochdale in the County of Lancaster Machinist
and FREDERICK WILLIAM PETRIE of 34 William Street Rochdale in the County of
Lancaster Machinist do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement:—
Our Improvements relate to that portion of Machinery for Washing or Cleansing
Wool or other fibrous material by which the scoured wool or other fibrous interinl
is transferred from the trough in which it has been Washed or cleansed to the
squeezing rollers and are made and based upon the mechanism for washing and
cleansing wool or other fibrous material described in the specifications of Letters
Patent No. 43 A.D. 1874 and No. 4261 A.D. 1880.
l'art of our improvements relate to the method of conveying wool or other fibreus
material from the trough in which the wool has been conveyed from the feed end
to the delivery end thereof, by means of the ordinary swing or vibratory rakos
when the squeezing rollers placed in proximity to the trough, have the bottom
roller placed below or partially below the level of the water line in the trough, but not
subinerged theroin.
In the specification of Letters Patent No. 43. A.D. 1874 (figs. 4. 5. 6) a fixed
grid or strainer carried at one end by a support, is placed above the level of the
water line in the trough, and resting upon the top of the trough at the other end,
the material being deposited thereon by an ordinary rake or other such apparatus and
then transferred to the squeezing rollers by a vibrating rake or othor suitable
apparatus as described and shown.
By our Improvement wo dispense with the fixed grid and its support and also of
the upper vibrating rake as therein described.
In place thereof, in combination with the ordinary swing rakes and actuated by
similar mechanical appliances, we use a vibrating rako armed with one or more rows
of prongs by which wool or other fibrous material is conveyed to the fall plate and
thence to the squeezing rollers. Fig. 1. is a longitudinal section of a Wool Washing
machine showing the squeezing rollers with bottom roller placed below or partially
below the level of the water line in trough, and the Improved delivery rake, in
combination with the ordinary swing rakes and actuated by simular mechanical
appliances.
a. b. are the squeezing rollers placed below or partially below the level of the water
line c in the washing trough A, but not submerged therein; d. is a faller plate by
which the wool or other fibrous material is conducted to the nip of rollers a. b ;—
e. is the rake sten to which one or more rows of teeth, f, are attached-g. an
adjustable radial rod to which the rake stem, e, is jointed as shewn at h. the radial
rod, g, being held and supported by a stand i.-, is a cast rail carrying the crank
shaft and balance disc k,-, line shaft driving the rake e. f. by the wheels m. n.
The wool or other fibrous material is conveyed by the ordinary swing rakes to
the delivery end of the washing trough, A and thence by the rake e. f. on to the
falle plate, d, and thence to the nip of the rollers, a. b.-We do not claim as
novel the general construction of and mode of driving the rake, e. f. but that
which we believe to be new, is the combination with the ordinary swing rakes, of
•

page_text: a swing rake having one or more rows of teeth or prongs and actuated by similar
mechanical appliances, when the squeezing rollers are placed below or partially bolow
the level of the water line c in the washing trough A but not submerged therein, as
substantially described.
Our Improvements further relate to machinery for washing and cleansing wool or
other fibrous material where the squeezing rollers are placed above, or proximately
above the level of the water line in the trough in which the wool or other fibrous
material is being washed or cleansed and where Slide Bars or other ordinary
travelling appliances are used for conveying the wool or other fibrous matorial to the
squeezing rollers.
In the Letters Patent No. 4261. A.D. 1880 wherein the squeezing rollers are
placed above or proximately above the water line in the washing trough a double
headed ordinary vibrating rake is shown by which the wool or other fibrous material
is transferred on to the Slide Bars or other travelling appliances used for con-
veying the wool or other fibrous material from the washing trough to the squeozing
rollors.
By our Improvements we dispense with the double headed Rake and substitute
therofor, a single adjustable vibrating rake held by a jointed radial rod and having a
check or stop motion at the point of delivery, thereby more effectually delivering the
wool or other fibrous material on to the Slide Bars or other travelling appliances
used for conveying the same to the squeezing rollers.
This part of our Invention is shewn at Fig. 2.-m. m showing the squeezing rollers
placed above or approximately above the water line n in the scouring trough B. o are
Sliding Bars or other ordinary travelling apparatus conveying the wool or other
fibrous material from the trough B to the nip of the squeezing rollors m. in—p is a
rake with a single row of teeth or prongs; p¹, the stem (9.) of which is at, r, bent,
and jointed at, s, to an adjustable radial rod attached to the stand, t, by this arrange-
ment the throw or sweep of the rako can be readily adjusted as required, so as to
deliver the wool or other fibrous material on to the Slide Bars, o, or other travelling
apparatus.
This construction of the rake causes it to have a check or stop motion at the point
of delivery.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed, we declaro that what we
claim is :-
1st. The combination of the delivery rake with one or more rows of teeth or
prongs with the fall plate and squeezing rollers when the bottom roller is placod
below or partially below the level of the water line as substantially described and
illustrated by fig. 1.
2nd. The combination of the said delivery rako with the ordinary swing or vibrating
rake and actuated by similar mechanical arrangement substantially described and set
forth.
3rd. The substitution of a delivery rako with a single row of prongs, in place of a
rake with more than one row of prongs for delivering the wool or other fibrons
