JOHN PETRIE, junior, of Rochdale, in the County of Lancaster, Machine
Maker. ** IMPROVEMENTS IN MACHINERY FOR WASHING OR SCOURING WOOL AND
OTHER SUCH FIBROUS MATERIALS, PARTS OF WHICH ARE ALSO APPLICABLE
TO WASHING RAGS AND OTHER MATERIALS USED IN THE MANUFACTURE OF
PAPER."
My Invention refers firstly to an improvement upon that machine for which
Letters Patent were granted to me dated 3rd January 1874, No. 43, and to that
part thereof in which the lower squeezing roller is placed below the level of the
liquid in the trough or bowl, and consists in a method of restoring the liquid which
has been squeezed from the material to the said trough or bowl. To accomplish this
I cause the squeezed-out liquid to fall into a suitable receiver within which there is
a travelling bucket or buckets whereby the said liquid is elevated and turned into
another receiver situated at a higher level, and from whence it flows back to the
trough or bowl.
The bucket or buckets I propose to employ are mounted upon centres carried
by a rotatory drum or disc, and when at sufficient elevation toothed gearing
arrives in contact with a fixed toothed sector, and the bucket or buckets are turned
over. These buckets I provide with teeth for lifting any loose material from the
fluid.

page_text: Secondly. My Invention consists in arrangements whereby I am enabled to use a
series of troughs or bowls having a constant stream running through them, and
with intervening squeezing rollers for passing the material to be operated upon
from one to another through the series, and also to enable the liquid to return to
the trough or bowl from which it had been taken by absorption of the material, or
to be run off to waste, or employ a trough or bowl if desired.
To accomplish these objects I employ a series of troughs or bowls, say two, of any
usual construction, and provided with ordinary rakes for moving the material
towards any ordinary lifting apparatus which elevates the material to the grips of
squeezing rollers situate between the two troughs or bowls, and which rollers
deliver it to the second of the series, a stream of the required liquid being delivered
thereto. This liquid is intended to flow from the second into the first trough or
bowls, and to enable it to do this I form passages from the one to the other, whereby
the obstruction of the intervening squeezing rollers is avoided, and in like manner
the series may be extended as required
For the other objects of my Invention I apply a receiver beneath the lower roller
for taking the liquid therefrom, and to this receiver I connect a pipe, the lower part
of which is provided with a tap or valve, which accordingly as it is moved opens
ways" which admit the flow of liquid from different sources, and by means of
which therefore 1 can return the liquid to the trough or bowl from which it came,
run it off to waste, or draw off from the trough or bowl.

This second part of my Invention is specially applicable to washing or scouring
rags used in the manufacture of paper.

by the said John Petrie in the Great Seal Patent Office on the 5th June
1878.
JOHN PETRIE, junior, of Rochdale, in the County of Lancaster, Machine
Maker. "IMPROVEMENTS IN MACHINERY FOR WASHING OR SCOURING WOOL
AND OTHER SUCH FIBROUS MATERIALS, PARTS OF WHICH ARE ALSO APPLICABLE TO
WASHING RAGS AND OTHER FIBROUS MATERIALS USED IN THE MANUFACTURE OF
PAPER."
My Invention refers firstly to an improvement upon that machine for which
Letters Patent were granted to me, dated 3rd January 1874, No. 43, and to that
part thereof in which the lower squeezing roller is placed below the level of the
liquid in the trough or bowl, and consists in a method of restoring the liquid which
has been squeezed from the material to the said trough or bowl.
This improvement is shewn at Figs. 1, 2, 3, 4, which represent the delivery end
of a washing machine with my improvement adapted. At 1 is the ordinary trough
or bowl of the machine, and at 2, 3, the squeezing rollers, the lower of which, as
before stated, is below the level of the liquid. The said lower roller runs in a dish 4
which by means of a channel 5 communicates with a reservoir 6, and it is from this
At 7 is
that the liquid has to be raised and transferred to the trough or bowl 1
a disc mounted upon a shaft 8 which is carried by the framework and driven by
any convenient means Upon this disc are mounted buckets 9 so as to be capablo
of turning with centres 10, each of which is provided with a toothed pinion 11 in
gear with wheels 12, the shafts of which (carried by the disc 7) are furnished with
star-formed parts 14. Fast with the frame 15 and therefore stationary is a
cam 10 and toothed segment 17, and this being the construction of the parts the
operation is as follows:-The disc 7 being caused to revolve in the direction of the
arrow, by this motion the buckets 9 successively enter the reservoir 6 and lift the
liquid therefrom. That one shewn at A being therefore changed and being pre-
vented from turning over by reason of the hollow of the star 12 being in contact
with the dead run of the stationary cam 16. Proceeding in this position in the
direction of the arrow the toothed wheels 12 arrive in gear with the fixed segment 17,
and being thus turned will cause the pinion 11 and bucket also to turn, a hollow 20
in the cam 16 permitting a point of the star 14 to enter. By these means the con-
tents of the bucket are turned out and fall into a trough 21, by means of which
they are transferred to the main trough or bowl 1 through a passage 22. After a
bucket has thus been emptied at the position B, a continued revolution of the disc 7
carries it downward, and the hollow part of the star 14 arriving in contact with the
circular part of the cam 16 the whole is carried bodily forward, as seen at C, ready
to scoop up another quantity of fluid.
Figs. 5 and 6 shew the bucket detached for the purpose of explaining that the
edge 25 thereof is formed with teeth to enable it to take up fibrous material which
may pass into the reservoir, such fibrous material being subsequently discharged
with the fluid into the receiver 21.
Secondly. My Invention consists in arrangements whereby I am enabled to use a
series of troughs or bowls having a constant stream running through them, and
with intervening squeezing rollers for passing the material to be operated upon from
one to another trough of the series and also to enable the liquid to return to the
trough or bowl from which it has been taken by absorption of the material, or to be
run off to waste, or empty a trough or bowl if desired.
This part of my Invention is shewn at the general views Figs. 7 and 8, and
detached views Figs. 9 and 10. At 30, 31, are two main troughs or bowls pro-
vided with rakes 32 and a lifting apparatus 33, which will be recognized as of
ordinary construction, the latter being used for elevating the material to the grip of
the pair of squeezing rollers 34, which rollers in this case are situate between the

page_text: two troughs or bowls 30, 31, and are intended to deliver the material taken up
from the former into the latter, while at the same time cleaner scouring or other
fluid delivered into the trough or bowl 31 passes into that shewn at 30, although
the squeezing rollers 34 intervene and are extracting dirty liquor from the material,
which material is fed by the ordinary lattice 35.
The arrangement for effecting this is as follows :-'
-The two troughs or bowls are
connected together by a passage 36 which by itself would form a simple commu-
nication from the one to the other, but within this passage is a distinct chamber 37,
within which is situate the lower squeezing roller, and as such chamber 37 is not of
the whole width of the passage 36 it leaves a channel 38 on each side thereof, along
which the cleaner liquid flows, while that which is squeezed from the material falls
into the chamber 37; and it will then be seen that any liquid delivered to the trough
or bowl 31 may flow into that shewn at 30 without being mixed with the liquid
passing from the squeezing rollers. The liquid falling into the chamber 37 inay be
disposed of in any desired manner, but according to my Invention I adopt special
means for that purpose.
This arrangement is as follows:-At 39 is a pipe connected to the bottom of the
chamber 37 connected to a three-way cock 40, which may however be replaced by
a suitable valve, and from this also proceeds a pipe 41 leading to the trough or
bowl 30 and a third pipe 42. Suppose it is desired that the liquid from the
squeezing rollers is to run off to waste, then the cock 40 is turned to make a con-
nexion between the pipes 39, 42, but if it be desired that the said liquid shall pass
into the trough 30, then the cock 40 is turned so as to make a communication
between the pipes 39, 41, or if it be desired to empty the trough 30, then in similar
manner the pipes 41, 42, are placed in communication.
I have above referred to the use of two troughs or bowls only, but in like manner
a series of three or more may be used if desired, and this part of my Invention may
be used for washing any fibious materials, but is particularly applicable to washing
or scouring rags used in the manufacture of paper.
Having thus described and ascertained the nature of my said Invention, and the
manner in which the same is to be performed, I desire it to be understood that I
claim as secured to me under the above in part recited Letters Patent, and for the
purposes above set forth,—
Firstly. As an improvement upon my former Patent aforesaid the use of the
apparatus, substantially as described for transferring the liquid delivered by the
squeezing rollers.
Secondly. The method of establishing a communication from one trough or bowl
to another with intervening squeezing rollers; also the use of the three-way cock or
other such appliance, as at 40.
In witness whereof, I, the said John Petrie, junior, have hereunto set my
hand and seal, this Fourth day of June, in the year of our Lord One
thousand eight hundred and seventy-eight.
