Complete Specification Left, 28th Mar., 1892-Accepted, 30th Apr., 1802
PROVISIONAL SPECIFICATION.
Improvements in Rotary Knife Cleaning and. Polishing Machines:
I, JOSEPH ATKINSON, of 11, Blackfriars, Street, Manchester, in the County
of Lancaster, Knife Cleaning and Polishing Machine Manufacturer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in rotary knife cleaning and polishing
machines and has for its object to provide a stay or rest which will more firmly
retain the knife in position when under operation and is more durable than
heretofore has been the case.
To this end my invention consists in providing the stay bracket fixed near the
aperture, through which the blade of the knife is inserted into the machine, with a
block having a groove formed therein.
The said block, I preferably form of vulcanized rubber fixed into the said stay
bracket by means of a pin or rivet or other means, which will permit of a ready
removal for the purpose of renewing the same, if necessary. The groove in the
rest block is adapted to receive the handle of the knife when the blade thereof is
in the machine or the blade when partly out of it and retain the knife laterally as
well as radially in position.

COMPLETE SPECIFICATION.
Improvements in Rotary Knife Cleaning and Polishing Machines.
I, JOSEPH ATKINSON of 11 Blackfriars Street, Manchester in the County
of Lancaster, Knife-cleaning and Polishing Machine Manufacturer, do hereby
declare the nature of this invention, and in what manner the same is to ne
performed, to be particularly described and ascertained in and by the following
statement :-
This invention relates to rotary knife-cleaning and polishing machines and has
for its object to provide a stay or rest which will more firmly retain the knife in
position when under operation and is more durable than heretofore has been
the case.
My invention consists in the improved construction or formation of the stay
brackets and will be more readily understood by referring first to the accompanying
sheet of drawings.
In the said drawings
Fig. 1 is a part sectional elevation of a rotary knife cleaning machine shewing
my improved stay bracket in position in section also.
Fig. 2, is a plan of a part of the said machine and my improved bracket. Figs. 3
and 4 are views of the parts composing the bracket.
In carrying out my invention I face that portion of the stay bracket which comes
in contact with the handle and blade of the knife with vulcanised indiarubber or its
equivalent as shown in Figs. 1 and 2, where A indicates the body of the bracket
and B the rubber block or face. The bracket A is preferably channelled as shewn
at a Figs. 1, 2, and 3, the block or face B is shewn secured in the channel a by a
pin e but it may be cemented or dovetailed in equally well. I form the block B
also with a channel or groove & Figs. 1, 2 and 4. The groove or channel b formed
in the face of the block B to receive and hold in position the handle of the knife

of a substance softer than the handle or blade of the knife retains it better in
position and preserves it from becoming scratched or damaged.

Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
"
In rotary knife cleaning and polishing machines the combination with a knife
stay-bracket of a fixed grooved block of indiarubber or its equivalent substantially
as described and indicated herein before and by the accompanying drawings.
