This invention has for its main object the prevention of the damage to the
wrapping of the top roller of a wool washing machine by the roughing of the
bottom or squeezing roller.
Hitherto the roughing of this roller in a wool washing machine has damaged
the wrapping of the top roller and in consequence the wool passing between the
rollers and necessitated the re-wrapping of the upper roller and the turning up of
the bottom or squeezing roller.
I accomplish my object by mounting a bar of iron parallel to the centres of the
rollers passing from side to side of the frame work of the machine and carried by
journals mounted on brackets secured to the frame work of the machine. To this
bar I secure by means of set screws a thin plate of iron of the length of the
bottom or squeezing roller sharpened at its lower. edge. The lower or sharpened
edge of this plate or blade is caused to press against the periphery of the bottom
roller by means of a lever or levers secured to the end or ends of the bar to this
lever or levers I suspend a weight capable of regulation in order to give the
required pressure of the blade against the periphery of the bottom roller.
The blade pressing against the surface of the roller maintains a smooth surface
and thus prevents damage alike to the wrapping of the top roller and the wool
passing between the rollers.
In order to prevent the water running off the ends of the rollers by the knife
pressing against the roller surface, I place at each end of the blade a vertical trough
which conducts the water down into the bowls of the wool washing machine.

IMPROVEMENTS IN WOOL WASHING MACHINES.
This invention has for its main object the prevention of the damage to the
wrapping of the top roller of a wool washing machine by the roughing of the
bottom or squeezing roller.
Hitherto the roughing of this roller in a wool washing machine has damaged
the wrapping of the top roller, and in consequence the wool passing between the
rollers is also damaged. The damage to the wrapping necessitates the re-wrapping
of the upper roller, and the frequent turning up of the bottom or squeezing roller.
In the accompanying drawings. Fig 1 represents the end elevation of the
squeezing rollers of a wool washing machine, one of the side frames being removed,
in order to better illustrate my invention which is applied to the bottom roller.
Fig 2 is a plan of the same shewing a portion of the roller and knife.
I accomplish my object by mounting a bar of iron A, parallel to the centres of
the squeezing rollers B, and B¹. passing from side to side of the framework C of
the machine, and carried by journals mounted on brackets D secured to the
framework C of the machine. To this bar A, I secure by means of set screws, a
thin plate or blade E of iron or steel of the length of the bottom or squeezing
roller B, sharpened at its lower edge. The lower or sharpened edge of this plate
or blade, is caused to press against the periphery of the bottom roller B by means
of a lever or levers F, secured to the end or ends of the bar A, and to this lever or
levers I suspend a weight W capable of regulation, in order to give the required
pressure of the blade E against the periphery of the bottom roller.
The blade pressing against the surface of the roller, maintains a smooth surface,
and thus prevents damage alike to the wrapping of the top roller B¹, and the wool
passing between the rollers, and also prevents any accumulation of the wool on
the bottom roller B, by which the liability of the rollers breaking is reduced.
In order to prevent the water splashing outwards by the knife or plate of iron
or steel E pressing against the roller surface as described, I place at each end of
the knife E, a vertical trough G, which conducts the water down into the bowls H
of the wool washing machine.
What I claim as my invention is:
The constant pressing of the edge of knife E against the periphery of the bottom
roller B, substantially for the purpose and in the manner described.
In witness whereof I the said John Campbell have hereunto set my hand and
seal this twenty eighth day of May in the year of our Lord One Thousand eight
hundred and eighty four.
