Improvements in Wool Washing and Scouring Machines and the like,
Year: 1898

Improvements in Wool Washing and Scouring Machines and the like,
I, JOHN DAWSON, of Lower Lane Ironworks, Milnrow, near Rochdale, in
the County of Lancaster, Machine Maker, do hereby declare the nature of this
invention to be as follows:-
-
This invention relates to improvements in wool-washing and scouring machines
and the like, the object being to provide improved prongs for the rakes and
improved mechanism for operating the jib rake attached to the main rake
frame.
J.
My invention consists essentially in substituting for the prongs used at present,
tubular prongs fastened in their carrying rails by suitable plugs and in utilising
an arrangement of gear wheels, shaft and crank, or the like, for operating the
jib rake.
In carrying out my invention I make use of tubular prongs of any suitable
material but preferably of brass or copper. These are made of the requisite
length and shape and may be seamless or otherwise. The thin ends or points
are plugged with brass or similar plugs which may be secured in a suitable
manner such as by soldering, scaming, rivetting or the like. The upper end of
each tube is firmly secured in its carrying rail by drilling the latter to a
suitable size, inserting the tube, and then fixing the latter by expanding the
metal by a suitable expander, or by the insertion of a short wood, metal, com-
position or metallic ferrule or other suitable means for securely fixing the tubes
in the rails. The prongs may be circular, triangular or oval in cross-section or
of other suitable shape. Prongs constructed as described are both considerably
stronger and lighter than those at present in use.
Referring to the second part of my invention I dispense with the curved slotted
link, referred to in the Specification of my Letters Patent numbered 25,033 of
1894, and, instead thereof I adjustably attach the jib rod to a crank pin carried
by a crank or a crank disc the latter being driven from one of the usual motion
shafts through a suitable arrangement of gear wheels. The crank pin is adjust-
able and the new mechanism is so arranged that the jib rakes are given a motion
in a direction as near as possible concentric with the curved plate at the end
of the machine, the object of such motion being to effectively push the wool
forward from the washing bowl to the travelling lattice which conducts the wool
away from the machine.

page_text: I, Jonx Dawson, of Lower Lane Ironworks, Milnrow, near Rochdale, in
the County of Lancaster, Machine Maker, 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:-
―
This invention relates to improvements in wool-washing and scouring machines
and the like, the object being to provide improved prongs for the rakes and
improved mechanism for operating the jib rake attached to the main rake
frame.
My invention consists essentially in substituting for the prongs used at present,
tubular prongs fastened in their carrying rails by suitable plugs and in utilising
an arrangement of gear wheels, shaft and crank, or the like, for operating the
jib rake.
The invention will be fully described with reference to the accompanying
drawings in which
Fig. 1 shows part sectional elevation, plan and cross section of one form of
fork and connection in accordance with my invention and
Figs. 2, 3, and 4 similar views of other arrangements of forks.
Fig. 5 is an end elevation, partly in section, of the improved means for operating
the jib rake and,
Fig. 6 a side elevation of same partly in section.
In carrying out my invention and referring more particularly to Figs. 1 to 4
I make use of tubular prongs or forks A preferably somewhat conical in shape
and of about the same length as those ordinarily in use. These prongs may,
however, be made of cylindrical tube and may be bent forward at their lower
ends as is often the case with other forms of prongs used in wool washing and
drying machines. The tubes may also be made of seamless material or rolled to
the shape required and the joint soldered or brazed. In some cases the cross
section, taken on line a and b, is circular as in Fig. 1, triangular as in Fig. 2,
U-shaped but still tubular, as in Fig. 3 and oval as in Fig. 4 but I would have
it distinctly understood that the cross section may even be square or of other
suitable shape so long as the tubular section is adhered to and the section may
vary at different parts of the tube. The section shown in Fig. 3 whilst being
strong displaces but little of the liquor used in washing the wool. The lower
ends of the tubes or points may be left open or, stopped up with brass or copper
plugs B as in Fig. 4 or otherwise closed. Each tube or prong may be secured to
its carrying bar C in various ways and the bar itself may be of varying cross
section. In Fig. 1 the bar is formed from a section of angle iron, in Fig. 2 it
is a plain flat bar, in Fig. 3 it is somewhat semicircular in cross section whilst
in Fig. 4 it is provided with a number of projecting bosses c to lengthen the
bearing surfaces for the tubes. In each case the bar or rail C is provided with
a suitable number of holes which are drilled and rimered out conical in Figs. 1, 3
and 4 though in Fig. 2 each hole is tapped to receive a screwed ferrule 1) fixed
to or forming part of the tube. In all cases the upper ends of the tubes are
preferably secured to the bars C by driving into them a short wood, metal, or
composite plug E which expands the tube, through the latter may be expanded
by the use of a tube expander. As a further security I sometimes use metal
clips secured to the bar C by setscrews f which may pass through the clips
and bind against the tubes A. In Fig. 2 as before indicated I use screwed
ferrules D. The tubes may also be further secured by passing a pin or cotter
transversely through the bar C and the tube. Prongs constructed as described

page_text: are both considerably stronger and lighter than those at present in use and may
be employed in both wool washing and drying machines.
Referring to the second part of my invention I dispense with the curved slotted
link, referred to in the Specification of my Letters Patent No. 25,083 of 1894,
and instead thereof I adjustably attach the upper end of the jib rod G
to a crank pin g carried by a crank or a crank disc H, the latter being fixed on
shaft driven from one of the usual motion shafts through a suitable
arrangement of gear wheels consisting of a pinion J gearing into a wheel J.
kare the usual wheels for driving the cranks and fork frame. The crank pin g
is adjustable and the new mechanism is so arranged that the jib rake K is given
a motion in a direction as near as possible concentric with the curved plate L
at the end of the machine, the object of such motion being to effectively push
the wool forward from the washing bowl to the shute plate M which conducts
the wool away from the machine to the squeezing rollers.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
1. In machines for washing and drying wool the use of tubular forks or prongs
such as described.
2. In machines for washing and drying wool the use of tubular forks or prongs
constructed and arranged substantially as described with reference to either
Fig. 1, 2, 3, or 4.
3. In machines for washing and drying wool the combination with tubular
prongs such as A of the means for attaching or fixing such prongs to their
carrying bars, consisting of clips and setscrews such as F and f with or without
plugs E as in Fig. 1, screwed ferrules D and plugs E as in Fig. 2, or plugs E
only as in Figs. 3 and 4 substantially as described.
4. In machines for washing wool of the type described the combination with
the jib rake K of jib rod G, adjustable crank pin g, crank or crank disc H,
shaft and train of wheels J and J for driving the latter substantially as and
for the purposes described.
5. The improved forks and jib working mechanism for wool washing and drying
machines constructed and arranged substantially as described and as shown in
the accompanying drawings.
