PROVISIONAL SPECIFICATION.
Improved Appliance for Adjusting the Discs of Knife Cleaning
Machines.
I, JAMES OSBORN SPONG, of 226, High Holborn, London, Domestic Appliances
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention has for object, certain appliances connected with the spindle
of the discs of knife cleaning machines for ready and reliable adjustment of
the discs by the simple turning of a ferrule from outside the casing.
The invention consists of a ferrule or collar with cam like ends to ride
against lugs, one of which is on a key free to slide in a keyway of the discs
spindle and in contact with the outer face of one of the discs or a collar or
shield thereon, the other cam bearing against the outer face of the other disc,
so that when the ferrule is turned by a spanner or like tool, the two discs can
be drawn closer together and adjusted to allow for wear of the cleaning leathers
or other media, the action of the ferrule being to push one disc and to draw the
other and so maintain the centralization with the knife insertion openings of
the casing.
A set screw may be employed to fix the ferrule after adjustment if required.

Improved Appliance for Adjusting the Discs of Knife Cleaning
Machines.
I, JAMES OSBORN SPONG, of 220, High Holborn, London, Domestic Appliances
Manufacturer, 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 has for object, certain appliances connected with the spindle
of the discs of knife cleaning machines for ready and reliable adjustment of
the discs by the simple turning of a ferrule from outside the casing.
For the purpose of my invention I make the ferrule or collar with cam like
ends to ride against lugs one of which is on a key free to slide in a key way
of the discs spindle and in contact with the outer face of one of the discs or
a collar or shield thercon the other cam bearing against the outer face of the

page_text: other disc so that when the ferrule is turned by a spanner or like tool the two
discs can be drawn closer together and adjusted to allow for wear of the cleaning
leathers or other media the action of the ferrule being to push one disc and
to draw the other and so maintain the centralization with the knife insertion
openings of the casing.
A set screw may be employed to fix the ferrule after adjustment if required.
My invention will be understood by reference to the annexed drawings.
Figure 1 elevation of my spindle appliances with the disc's collars set wide
apart as for a new knife cleaning machine.
Figure 2 similar elevation of the same with the disc's collars closed inwardly
and equally towards the central line and true to the openings into which the
knives are inserted into the casing.
Figure 3 part sectional elevation of my disc's adjustable appliances operable
from and connected to the spindle of a knife cleaning machine.
A, spindle. B key way of same. C key slidable thereon. D, D¹, heads of
key, E double cam faced ferrule revolvable on spindle A and having the
reverse thread or operable faces of cams F, G, abutting against the head D
of key C and of stud H of collar I respectively to push the disc J inwardly
and simultaneously with the head D to draw the other collar K of the disc L
inwardly and to the same extent as the disc J. M tip of spindle for engagement
in journal of outer supporting frame; N part of the spindle A held in journal
of near supporting frame; P square of spindle for reception of crank handle.
These latter parts are of the usual kind and form no portion of my invention.
therefore I do not show a view of the machine.
The ferrule by its rim Q is easily adjustable by hand but if desired a spanner
may be used for adjusting the discs J, L, the set screw R serving to fix the
parts when so adjusted, and to enable the adjustment to be perfectly reliable
when decided upon, I make an annular groove S around the spindle A for the
fixture of the set screw R and the rigid fixation of the ferrule E until a fresh
adjustment of the discs J, L, becomes necessary for which the set screw R is
slackened and the ferrule E gently turned to the required extent and the set
screw again fixed without removing any part from the machine.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed I declare that what
I claim is:
1. As disc's adjustable appliances in or to a knife cleaning machine a double
headed key C in spindle A, said heads being operable by a reverse cam ferrule E
carried by the spindle A and acting against head D for one disc and against
stud H of the other disc for simultaneous adjustment of the two discs as and
for the purpose specified and substantially as represented.
2. The double or reverse faced ferrule E loosely mounted on axle A of knife
cleaning machine for simultaneously adjusting the cleaning discs J, L, substan-
tially as described and preferably by the double headed sliding key C and
stud H as represented.
