PROVISIONAL SPECIFICATION.
Improvements in Wool-washing or Carbonizing Machines.
I, WALTER BRIERLEY, of Penny Bank Chambers, Halifax, in the County of
York, Patent Agent, do hereby declare the nature of this invention which has
been communicated to me by Luther Andrew Peckham, of Oswego Falls, in the
County of Oswego, in the State of New York, U.S.A., to be as follows:-
This invention consists in an improved organization of a machine designed for
either washing or carbonizing wool and other loose fibres, which machine possesses
superior efficiency in its operation combined with increased economy in the
consumption of time in washing or treating the fibres, and prokluces greatly
improved results.
According to this invention, above the main washing bowl is placed another
bowl which is separate and distinct from the lower bowl, and constitutes the
receptacle in which the fibres are either washed or carbonized. Inasmuch as the
machine is chiefly designed for washing wool, I will refer to said parts respectively
as the "liquid bowl" and the "washing bowl" in my further description of the
machine. Said upper or washing bowl is securely mounted on the lower bowl by
standards, and receives the suds or liquid from the lower bowl by means of a force
pump having its suction pipe connected to the lower bowl at the fibre discharge
end of the machine, and the discharge pipe extending along the side of the said
bowl, and up at the opposite end of the bowl in the manner hereinafter described.
There is the usual feed apron by which the fibres are delivered to the upper or
washing bowl. In order to cause the fibres to be effectually delivered from said
apron and deposited in the adjacent end of the bowl, there is placed across the
upper bowl in front of the delivery end of the apron, a vertically disposed breast,
and a pipe parallel between said breast and feed apron, and above the latter. Said
pipe is connected to the discharge pipe of the pump to receive the liquid therefrom,
and is provided with a downwardly directing discharge slot extending preferably
throughout the entire width of the latter, and having a flaring mouth
to throw a downward stream of liquid between the breast and apron,
and against said breast and apron, and thereby wash the fibres froni
the discharge and of said apron, and throw said fibres down into the
bowl. There is also connected to the discharge pipe of the aforesaid pump,
another pipe which extends across the exterior of the end of the upper bowl
beneath the return bottom portion of the apron, and provided with a discharge
spout extending lengthwise of the pipe and in an upward and inward direction
into the bowl between the top of the latter and bottom of the apron, by means of
which spout a stream of liquid is thrown against the bottom of the apron to cleanse
the same from the fibres and throw them into the bowl. To prevent the fibres
from adhering to the said end of the bowl, there is provided for the bottom of the
spout, downwardly directed porforations adjacent to the end of the inner side of
the end wall of the bowl, so that the spray of liquid issuing from said perforations
will cleanse said wall.
The washbowl is provided with one or more depending sand traps, separated

page_text: from the lower bowl, each of said traps being covered by a perforated plate or
strainer which allows the sand and grit to pass through it and into the trap,
wherein said substances are collected and thus retained separated from the liquid
in the lower bowl. To allow said traps to be cleaned simultaneously with the
cleaning of the lower bowl, I connect to the pump discharge pipe, branch pipes
which extend into the said traps, and have their inclosed portions perforated to
throw sprays of liquid into the traps. Each trap has connected to it a discharge
pipe which is provided with a gate or valve which is closed during the washing
process. A valvo in the connection of the branch pipes with the pump discharge
pipe is also to be closed during said process.
To allow the liquid from the pump discharge pipe to be conducted into the
branch pipes when desired, I provido said discharge pipe with a valve or stop cock
beyond the connection of said branch pipes with the pump discharge pipe.
In cleaning out the machine, the stop-cock of the usual outlet in the bottom of
the bowl is opened, and after closing the stop-cock, the valves are opened. The
pump being in operation causes the liquid to be forced into the branch pipes, from
whence it enters the traps and washes out the sand and grit which is allowed to
escape through the discharge pipes into the lower bowl.
If desired, a single sand-trap may be employed, which trap extends nearly or
quite the entire length of the upper bowl and has two branch pipes extending into
opposite ends thereof, the bottom of the trap being inclined from the ends to the
centre where the discharge pipe is attached.
I employ devices for intermittently squeezing the wool upon the bottom of the
bowl, so as to press the suds or liquid out of the wool and carry out with it the
sand, grit, dirt, and grease. Said means of washing the wool may be constructed
in various ways without departing from the spirit of my invention. The squeezers
may be either of the form of rollers extending across the bowl, or consist of boxes
placed inverted over the bottom of the bowl, and provided with outwardly opening
Salves for the escape of the air displaced in the boxes during the operation of sub-
merging them in the liquids, or said boxes may be permanently closed, and
furthermore, the squeezer may extend the entiro length of the bowl. Tho
squeezing may be effected either by causing the aforesaid squeezers to move toward
and from the bottom of the bowl, or by causing the washing bowl to rock
vertically. The latter motion may be produced by an eccentric attached to a
rotary shaft, aud carrying upon its periphery one end of the bowl, which is hinged
at its opposite end; but inasmuch as it requires considerable power to impart said
motion to the bowl, I prefer to secure the samo permanently in a horizontal or
nearly horizontal position, and employ suitable ineans for moving the before
described squeezers towards and from the bottom of the bowl. This may be
accomplished either by oscillatory levors at opposite sides of the bowl, and having
two arms fulcrumed on the axes of a pair of the squeezers, or when the squeezer
extends nearly the entire length of the bowl, said squeezer may be caused to receive
its vertical motion by hanging it on eccentrics fastened to rotary shafts over
opposite ends of the squeezor. I prefer, however, to employ the oscillatory levers,
which are each provided with an upwardly extending arm, and two arms extend-
ing laterally in opposite directions from the lower end of the upwardly extending
arm, and preferably fulcrum of said lever is on the axes of two rollers which are
pivoted to the ends of said arms. By oscillating said levers in planes at right
angles to the axes of the rollers, one of said rollers is lifted by one arm of each
lever, while the other arm presses down the other roller, and is fulcrumed thereon,
and said motion of the rollers is reversed during each stroke of the levers. The
levers of each pair of rollers are united by a cross-bar to compel the two levers to
move in unison.
I prefer to employ a plurality of squeezing rollers arranged in nairs, each of
which pairs is connected to a pair of levers united as aforesaid, and in order to
operate all of said rollers in unison, I couple together the cross-bars by longi-
tudinal rods. One of the lovers has its third or upwardly projecting arm provided

page_text: with an extension, which by a pitman is connected to a wrist-pin on a rotary
wheel, which when in motion imparts a rocking motion to the levers by means of
the pitman.
In order to guard against undue strain on the levers and their connections,
incident to an uneven distribution of the wool in the bowl, I form the pitman with
a longitudinally yielding joint obtained by forming the pitman of two sections
connected end to end by a spiral spring in a sleevo, inclosing the adjacent ends of
the pitman sections and bearing against collars on the ends of said sections. I
also provide means for varying the degree of the lifting of the rollers by providing
a wheel with a diametric slot for the reception of the bolt by which to clamp on
said wheel a block which has attached to it the wrist-pin to which the pitman is
connected. Said slot allows the wrist-pin to be set either in the centre of the
wheel or any desired distance therefrom.
In order to impart to the rollers a rotary motion so as to cause the wool to be
moved towards the discharge end of the bowl, I attach to the axes of said rollers
at one side of the bowl, gear wheels, and fasten to the same side of the bowl,
gudgeons, upon which are mounted intermediate pinious meshing with the gear
wheels of a pair of rollers. To the same gudgeons are fastened beveled gears
meshing with beveled pinion attached to a rotary shaft which extends along the
side of the bowl. The means for transmitting motion to the shaft may be varied
in numerous ways, and I therefore do not limit myself in this respect.
There are squeeze-rolls, which extend across the discharge end of the bowl, to
express the liquid from the washed wool. These rolls I prefer to arrange with
their bite nearly or quite in line with the bottom of the interior of the bowl.
For delivering the washed wool to the rolls, I have devised oscillatory forks,
which are pivoted one in rear of the other, but operate through parallel paths,
and each delivers the washed fibres to the rolls without assistance from the other,
instead of employing two or more rakes or forks delivering the washed fibre one
to another as heretofore proposed. Each of these forks extends across the bowl
and consists of a frame pivoted in suitable bearings secured to the sides of the
bowl. Said frame is thus allowed to swing in an arc towards and from the squeeze
rolls or discharge end of the bowl. To a horizontal cross-bar on the lower end of
the frame, are pivoted the tines which are of such length as to cause them to be
inclined towards the rolls, by the free ends of the tines sliding on a metal plate
heroinafter described. It will be observed that each fork travels up to the delivery
end of the bowl, and thereby delivers the washed fibre to the squeezo rolls without
assistance from the other forks. I preferably form said tines with auxiliary
teeth projecting from the bottom of the tines, and also hingo to the rear portion
of the main tine, a supplemental tine.
That portion of the bottom of the bowl which is under the aforesaid forks is
formed of a metal plate which extends to the squeeze rolls, and adjacent to said
rolls is another plate which is countersunk in the top of the first mentioned plate.
The back of the plato is perforated, and forms the sole outlet of the suds or liquid
from the washing bowl to the lower bowl or reservoir.
To properly guide the free ends of the tines, and to enable them to obtain
effective hold upon the wool, I provide the top of the plate with longitudina!
grooves in which the tines slide, and also provide said plate with rows of teeth
between the grooves, which teeth stand with their free ends pointing towards the
bite of the squeeze rolls.
The tines of each fork are arranged intermediate with those of the other, and
the two forks are oscillated so as to cause one fork to recede from the rolls, while
the other fork pushes the washed fibre towards the said rolls. The teeth on the
metal plate prevent the fibre from being drawn back by the receding fork.
The aforesaid motion of the forks is derived from a pitman connected to two
cranks which extend in opposite directions from their axes, and are preferably on
the same shaft, which receives rotary motion from the driving shaft by inter-
meshing gears, I do not, however, limit myself to this particular mechanism for

page_text: actuating the aforesaid crank-shaft, as the same may be effected by other suitable
means.
In order to guard against undue strain on the forks and their connections,
incident to the tines of said forks engaging an excessive amount of fibre, I provide
a pitman with suitable spring couplings, which allow the said pitman to yield
longitudinally when subjected to excessive strain. One form of said spring
couplings consists of a sleevo forming one end portion of the pitman, and receiving
in it a portion of a rod which constitutes the other end portion of the pitman.
Said rod passes through a cap secured to the end of the sleeve, and the inner end
of the rod has affixed to it a head, between which and the cap is a compressed
spiral spring surrounding the rod.
Another salient feature of the invention is a screen or strainer in the end of the
lower bowl directly under the plate, which is provided with the sole outlet for
the liquid from the upper bowl to the lower bowl. This strainer extends across
the bowl, and to the top thereof and under the lower squeeze roll. This strainer
serves to collect all the fine fibres which may escape from the upper bowl. To
carry these fine fibres back to the upper bowl, I connect the suction pipe of the
pump to the lower bowl at a point to communicate with the interior of the afore-
said strainer or screen, preferably near the base thereof, and thus convey the fibres
with the liquid to the bowl. By this means is effectually provented the waste of
said fibres.
One of the means of imparting rotary motion to the rollers cousists of pawls or
dogs mounted on the bowl and engaging with ratchets on the ends of the rolls
during the descent of the latter.

I. WALTER BRIERLEY, of Penny Bank Chambers, Halifax, in the County of
York, Patent Agent, do hereby declare the nature of this invention which has
heen communicated to me from abroad by Luther Andrew Peckham, of Oswego
Falls, in the County of Oswego, in the State of New York, U.S.A., and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This invention relates to improvements in machines for washing or carbonizing
wool and other fibres and is designed as to possess a superior efficiency in its
operation, together with greater economy in the time occupied in washing or
treating the wool or fibres, also producing better final results than heretofore.
Such being the nature and object of the said invention, the following is a
complete description of same, reference being had to the accompanying drawings
in which like letters of reference refer to similar parts throughout.

Fig. 20 is a longitudinal sectional view of one of the spring-coupled links, and
Fig. 21 illustrates a modification of the mechanisms for imparting rotary motion
to the rollers employed for squeezing the wool or fibre in the suds or other liquid
within the bowl.
According to this invention A represents the bowl, which constitutes the
reservoir for the liquid in which the wood or other fibre is to be treated. Above
this bowl I place another bowl A', which is separate and distinct from the lower
bowl and constitutes the receptacle in which the fibres are either washed or
carbonized.
As the machine is chiefly designed for washing wool I will refer to said parta,
respectively, as the "liquid-bowl" and the washing-bowl" in my further
description of the machine. Said upper or washing bowl is securely mounted on
the lower bowl by standards A" A" and receives the suds or liquid from the lower
bowl by means of a force-pump B, having its suction-pipe B connected to the
lower bowl at the fibre-discharge end of the machine, and the discharge-pipe B
extending along the side of said bowl and up at the opposite end of the bowl in
the manner hereinafter described, A is the usual feed-apron by which the fibres
are delivered to the upper or washing bowl A'.
In order to cause the fibres to be effectually delivered from said apron and
deposited in the adjacent end of the bowl, I place across the upper bowl in front
of the delivery end of the apron C a vertically-disposed breast C, and place a
pipe D parallel between said breast and feed-apron and above the latter, as shown
more fully in Fig. 7 of the drawings. Said pipe is connected to the discharge-
pipe B of the pump to receive the liquid therefrom and is provided with a
downwardly-directed discharge-slot D', extending, preferably, throughout the
entire width of the latter and having a flaring or trumpet mouth to throw a
downward stream of liquid between the breast C and apron C and against said
breast and apron and thereby wash the fibres from the discharge end of said and
throw said fibres down into bowl, as indicated by arrows in Fig. 7 of the drawings.
Thero is also connected to the discharge-pipe of the aforesaid pump another pipe E,
which extends across the exterior of the end of the upper bowl beneath the return
bottom portion of the apron C and is provided with a discharge-spout E', extend-
ing lengthwise of the pipe E and in an upward and inward direction into the
bowl between the top of the latter and bottom of the apron, by means of which
spout E a stream of liquid is thrown against the bottom of the apron to cleanse
the same from the fibres and throw them into the bowl. To prevent the fibres from
adhering to the end of the bowl, I provide the bottom of the spout E' with down-
wardly-directed perforations c, adjacent to the end of the inner side of the end

page_text: wall of the bowl, so that the spray of liquid issuing from said perforations will
cleanse said wall.
The washbowl A' is provided with one or more depending sand-traps F,
separated from the lower bowl, each of such traps being covered by a perforated
plate or strainer R, which allows the sand and grit to pass through it and into the
trap wherein such substances are collected and retained separated from the liquid
in the lower bowl. To allow the traps to be cleaned simultaneously with the
cleaning of the lower bowl A, I connect to the pump-discharge pipe B branch
pipes, which extend into the said traps and have their inclosed portions per-
forated to throw sprays of liquid into the traps, as clearly shown in Fig. 11 of the
drawings. Each trap has conneoted to it a discharge-pipe F, which is provided
with a gate or valve G, closed during the washing process. A valve H in the
connection of the brauch pipes with the pipe B is also to be closed during said
process.
To allow the liquid from the pump-discharge pipe B to be conducted into the
branch pipes F when desired, I provide said discharge-pipe B with a valve or
stop-cock II beyond the connection of said branch pipes with the pipe B", as
shown in Fig. 2 of the drawings.
In cleaning out the machine the stop-cock of the usual outlet Fun in the bottom
of the bowl A is opened, and after closing the stop-cock H the valves H and G
are opened. The pump B being in operation causes the liquid to be forced into the
branch pipes F, from whence it enters the traps and washes out the sand and grit
which is allowed to escape through the discharge-pipes F" into the lower bowl A.
If desired, a single sand-trap may be employed, as represented at Fin
Figs. 14, 15, and 16 of the drawings, which trap extends nearly or quite the entire
length of the upper bowl and has two branch pipes F1, extending into opposite
ends thereof, the bottom of the trap being inclined from the ends to the centre,
where the discharge-pipe I is attached.
I employ devices for intermittently squeezing the wool upon the bottom of the
bowl, so as to press the suds or liquid out of the wool and carry out with it the
Band, grit, dirt, and grease. The squeezers may be either of the form of rollers
extending across the bowl A', as represented at I, or consist of boxes I placed
inverted over the bottom of the bowl and provided with outwardly-opening
valves a for the escape of the air displaced in the boxes during the operation of
submerging them in the liquids, or said boxes may be permanently closed, as
shown at I, or the squeezer may extend the entire length of the bowl, as shown
at I in Fig. 19 of the drawings. The squeezing may be effected either by
causing the aforesaid squeezers to move toward and from the bottom of the bowl,
as shown in the majority of the figures in the drawings, or by causing the washing-
bowl to rock vertically, the latter construction being represented in Fig. 18, in
which the bowl is designated A. The latter motion may be produced by an
eccentric K, attached to a rotary shaft K and carrying upon its periphery one end
of the bowl which is hinged at its opposite end, as shown at K"; but inasmuch
as it requires considerable power to impart said motion to the bowl I prefer to
secure the same permanently in a horizontal or nearly horizontal position and
employ suitable means for moving the before-described squeezers toward and from
the bottom of the bowl. This may be accomplished either by oscillatory
levers L L at opposite sides of the bowl and having two arms L' L', fulerumed on
the axos of pair of the squeezers, or, when the squeezer extends nearly the
entire length of the bowl, said squeezer may be caused to receive its vertical motion
by hanging it on eccentrics M, fastened to rotary shafts Mover opposite ends of
the squeezer, as represented in Fig. 19 of the drawings. I prefer, however, to
employ the levers L L, which are each provided with an upwardly-extending
arm L and two arms L L, extending laterally in opposite directions from the
lower end of the arm L, and preferably fulcrum said lever on the axes of two
rollers II, which are pivoted to the ends of said aruis. By oscillating said levers
in planes at right angles to the axes of the rollers one of said rollers is lifted by

page_text: one arm of each lever, while the other arm presses down the other roller and is
fulcrumed thereon, and said motion of the rollers is reversed during each stroke
of the levers. The lovers of each pair of rollers are united by a cross-bar N to
compel the two levers to move in unison.
I prefer to employ a plurality of squeezing-rollers I I, arranged in pairs, each
of which pairs is connected to a pair of levers L, united as aforesaid, and in order
to operate all of said rollers in unison I couple together the cross-bars N N by
longitudinal rods N. One of the levers L has its third or upwardly-projecting
arm L provided with an extension L, which, by a link O, is connected to a
wrist-pin P on a rotary wheel Q, which when in motion imparts a rocking motion
to the levers L by means of the link.
In order to guard against undue strain on the lovers and their connections,
owing to uneven distribution of the wool in the bowl, I form the link with a
longitudinally-yielding joint obtained by forming such link of two sections con-
nected end to end by spiral spring bin a sleeve b¹, inclosing the adjacent ends of
the link-sections and bearing against collara 6 on the ends of said sections, as
illustrated in Fig. 13 of the drawings. I also provide means for varying the
degree of the lifting of the rollers II by providing the wheel Q with a diametric
slot d for the reception of the bolt by which to clamp on said wheel a block
which has attached to it the wrist-pin to which the link 0 is connected. Said
slot allows the wrist-pin to be set either in the centre of the wheel or any desired
distance therefrom.
In order to impart to the rollers II a rotary motion so as to cause the wool to
be moved toward the discharge end of the bowl, I attach to the axes of said rollers,
at one side of the bowl, gear-wheels ce and fasten to the same side of the bowl
gudgeons upon which are mounted intermediate pinions e', meshing with the
gear-wheels of a pair of rollers I I. To the same gudgeons are fastened beveled
gears, meshing with beveled pinion f attach to a rotary shaft g, which extends
along the side of the bowl, as more clearly shown in Fig. 3 of the drawings. The
meaus for transmitting motion to the shaft g may be varied in numerous ways.
SS represent the squeeze-rolls, which extend across the discharge end of the
bowl to express the liquid from the washed wool. These rolls I prefer to arrange
with their bite nearly or quite in line with the bottom of the interior of the
bowl A', as shown in Figa. 6 and 10 of the drawings.
For delivering the washed wool to the rolls S S, I have devised oscillatory forks,
which are pivoted one in rear of the other but oporate through parallel paths, and
each delivers the washed fibres to the rolls without assistance from the other,
instead of employing two or more rakes or forks delivering the washed fibre one
to another, as heretofore proposed. Ench of these forks extend across the bowl
and consists of a frame T, pivoted in suitable bearings hh, secured to the sides of
the bowl. Said frame is thus allowed to swing in an arc toward and from the
squeeze-rolls S S or discharge end of the bowl. To a horizontal cross-bar T¹ on
the lower cud of the frame T are pivoted the tines tt, which are of such length as
to cause them to be inclined toward the roll S S by the free ends of the tines
sliding on a metal plate hereinafter described. It will be observed that each fork
travels up to the delivery end of the bowl and thereby delivers the washed fibre
to the squeeze-rolls S S without assistance from the other forks. I preferably
form said tines with auxiliary teeth, projecting from the bottom of the tines,
and also hinge to the rear portion of the main tine a supplemental tine (".
That portion of the bottom of the bowl which is under the aforesaid forks is
formed of a metal plate U, which extends to the squeeze-rolls S S, and adjacent
to said rolls is another plate U, which is countersunk in the top of the plate U.
At the back of the plate U the plate U is perforated and forms the sole outlet of
the suds or liquid from the washing-bowl A to the lower bowl or reservoir A.
To properly guide the free ends of the tines and to enable them to obtain
effective hold upon the wool, I provide the top of the plate U with longitudinal
grooves ii, in which the tines slide, as more clearly seen in Fig. 8 of the drawings,

page_text: and also provide said plate with rows of teeth botween the grooves, which teeth
stand with their free ends pointing toward the bite of the squeeze rolls S S.
The tines of each fork aro arranged intermediate those of the other, and the two
forks are oscillated so as to cause one fork, to recede from the rolls S S while the
other fork pushes the washed' fibre toward said rolls.
The teeth on the plate U prevent the fibre fipm being drawn back by the
receding fork.
The aforesaid motion of the forks is derived from links V V, connected to two
crunks jj, which extend in opposite directions from their axes and are preferably
on the same shaft which receives rotary motion from the driving-shaft o by
interineshing gears of ol
In order to guard against undue strain on the forks and their connections
incident to the tines of said forks engaging an excessive amount of fibre, I provide
the links VV with suitable spriug-couplings, which allow said links to yield
longitudinally when subjected to excessive strain. One form of said spring-
couplings is illustrated in Fig. 20 of the drawings, and consists of the sleeve m,
forming one end portion of the link and receiving it in a portion of a rod m³, which
constitutes the other end portion of the link. Said rod passes through a cap n,
secured to the end of the sleeve, and the inuer end of the rod has affixed to it a
head n', between which and the cap n is a compressed spiral spring n", surrounding
the rod m¹.
Another feature of my invention lies in the screen or strainer J in the end of
the lower bowl A, directly under the plate U, which is provided with the solo
outlet for the liquid from the upper bowl to the lower bowl. This strainer extends
across the bowl and to the top thereof and under the lower squeeze-roll S, as shown
in Fig. 6 of the drawings. This strainer serves to collect all the fine fibres which
may escape from the upper bowl. To carry these fine fibres back to the upper
bowl A', I connect the suction-pipe B' of the pump B to the lower bowl A at a
point to communicate with the interior of the aforesaid strainer J, preferably near
the bass thereof, and thus convey said fibres with the liquid to the bowl A¹. By
this means I effectually prevent the waste of said fibres.
One of the means of imparting rotary motion to the rollers II is shown in
Fig. 21 of the drawings, and consists of pawls or dogs r, mounted on the bowl A¹
and engaging ratchets on the ends of the rolls II during the descent of the
latter.
