I, FREDERICK BISMARK OAKES, of 3, Alexander Terrace, Slade Lane, Longsight,
Manchester, Manager, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is improvements in knife cleaners and is applicable
to those knife cleaners which are made with india rubber rollers or other such
rollers which are liable to wear. These rollers are mounted on shafts working
in bearings in a frame or stand being geared one with another by means of small
cog wheels on one side of the frame.
Hitherto when the cleaning surface of the rollers have worn away they have
been adjusted by means of set screws which have been screwed down upon the
bearings thus altering the relative positions of the axles and so causing the cog
wheels to bite into one another often being the means of them breaking or causing
the frame to break.
My invention obviates this in the following manner: -I arrange the centre of
the roller shafts at practically equal distances in a triangular shape the centre of
the top shaft being slightly to the one side over the centre of the bottom roller
shaft. I attach two eye bolts upon the top shaft and carry them down to any con-.
venient position on the stand or frame and by means of winged nuts which screw
upon these bolts can readily adjust the position of the rollers when worn the
action being so that although the rollers are thus adjusted the relative position
of the centre of each shaft practically remains the same thus obviating the diffi-
culty of the cogs upon the gear wheels biting or bearing so far into one another
and doing away with strain causing the breaking of the frame or stand as before
explained.

manner the same is to be performed, to be particularly described and ascertained in
and by the following statement:-

Hitherto when the cleaning surfaces of the rollers have worn away they have
been adjusted by means of set screws which have been screwed down upon the
bearings thus altering the relative positions of the axles and so causing the cog
wheels to bite into one another too far often being the means of them breaking or
causing the frame to break and the object of my invention, is to obviate this and
will be readily understood by reference to the accompanying drawings upon which
I have illustrated one way of carrying out the same.
Figure 1 is a front view
Figure 2 a sectional elevation on line 1, 2 but with out the cog wheels or rollers
these being represented by dotted lines.
A is the frame of the knife cleaner which has extensions (B) for carrying
bolts (C) in the lugs (C¹) these bolts have worms or screw threads cut upon them
and are actuated by thumb wheels (D) the cleaning rollers E & E¹ shown dotted
in Figure 2 are mounted on shafts F and F the top one (F) being supported in
moveable bearings (G) which have teeth in them one extremity engaging with
the worm or screw thread on the bolts (C) and moving on the curve or rounded
portions (J) of the frame or pivoted on a shaft or pivot (K) the lower roller
shaft (F) being mounted in the fixed bearings (H).
The action being as follows: --When the wearing surface of the rollers (E)
and (E) are worn all that is necessary to do is to turn the thumb wheels D
operating the worms, on the bolt (C) which engages with the teeth on the bear-
ings (G) thus bringing the top roller (E) and shaft (F) down until it meets the
surface of the bottom roller (E) thus allowing the driving cog wheels shown
dotted on shaft (F) to remain engaged in the same working position with the cog
wheel on K and obviating the danger of them biting or engaging too deeply with
each other and the strain which causes the frame to break as before explained.
Although I have described and shown one method of achieving the desired end
I do not confine myself to this, as the top bearing may be instead of having teeth,
terminate in a nut or lug which can travel on the bolts (B) and act in a similar
manner to the aforesaid teeth.

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: ;-
Improvements in knife cleaners consisting of adjustable bearings and rollers
made and operated substantially as and for the purpose herein set forth and shown
upon the accompanying drawings.
