PROVISIONAL SPECIFICATION:
Improvements in Machines for Cleaning or Polishing Knives or like
Articles:
I, JOSEPH MATTHEW SELLERS of the Fum of William Sellers and Sons
of Keighley in the County of York, Machine Makers, do hereby declare the nature
of this invention to be as follows, that is to say
-
It relates to the class of machines wherein rotary rollers usually of indiarubber
are employed for revolving in contact with the surfaces of the knife or other
article to be cleaned, and this said invention, consists of arranging and mounting
these rollers so that they may be adjusted to occupy such relative positions as the
article to be subjected to their actious may require.
To attain this object I mount one of the rollera in the usual form. of trough-
shaped bearings, which is made to be attached to any suitable support as a table or
the like either by screws or the well known form of clamping device.
The other roller is mounted on leser arms which are arranged, to bo operated, by
screw or other meaus so as to allow this roller to be moved further from or nearer
to the first named roller as may be desired to meet the requirements of a thicker or
thinner knife or article passing between them, by which means whether such article
is the thin blade of a knife or the thick handle of a spoon or fork, the rubbing
surfaces of the rollers may be regulated to press upon them in an equal degroc,
while the wheels for diving same are allowed to remain the same depth in gear
with each other at one time as at another, the movement of said roller when brought
further from the other roller taking its driving wheel over a course parallel with
the periphery of the main driving wheel.
The level upon which the roller is mounted is preferably of a bifurcated form,
the roller being carried by the bifurcated aim while the holding screw is carried by
the other atm which I arrange to operate in proximity with an appropriately
formed curved projection extending from the framework.
This projection is arranged to allow the adjusting or holding sorew passing
through the single aim of the bifurcated lever to press against it, and its form is
such that any force acting upon it by reason of any article passing between the
rolleis tending to force said rollers apart,,causes it to more firmly press against the
said projections.
In connection with this machine the usual biush or grooved roller for cleaning.
forks or like articles, may be employed, however I make such grooved roller,
which is of india-rubber, so that its body part aud. its ridges or projecting rinis are
integral.

I, JOSEPH MATTHEW SELLERS of the Fum of William Sellers and Sons
of Keighley in the County of York, Machine Makers, 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, that 19
to say
It relates to the class of machines wherein rotary rollers usually of indiarubber

rollers so that they may be adjusted to occupy such relative positions as the
articles to be subjected to their actions may requie
In the accompanying sheet of drawings,
Figs 1 and 2 are back and end elevations of mechanism made in accordance with
my invention, the wheel guard in cach view being shown in section in order that
the gearing wheele might be more clearly seen
Fig 3 is a sectional end elevation illustrating the wheel bearings.
Fig. 4 is a similar view to Fig 3 but shows the relative positions of the parts
when the rollers have been reduced in size by wear or otherwise.
To attain the object of my invention I mount the roller am the usual form of
trough-shaped bearings b, which are made to be attached to suitable framework c
on to any suitable support as a table or the like either by screws or the well known
form of clamping device.

The other roller d is mounted on lever aims ff which are arranged to be
operated if desired by any screw or other mechanism, or they may be formed so
that the arm 2 is common to them both, in which case an opening g is made
therem so that it, said arm, may take over a quadrant or curved projection
order that when it is moved to adjust the roller d this latter may be held in such
position by the set screw Z, thus whether the article pass.ng between the rollers a
and necessitates the adjustment of these latter at a greater or less distance apart,
as also when the rollers a and d are of less diameter as shown by Fig 4, the teeth
of the wheels m, which impart motion from the handle o to the roller a, remain
the same depth in gear with each other at one time as at another, since the path in
which the axis of the roller a is moved during its adjustment is concentric with the
pitch line of the teeth of the wheel m.
The curved surface of the projection is made so that the distance between it
and the centre of the wheel m increases as it approaches the benings b, by which
means any pressure on force which tends to move the roller d fiom contact with the
1olle a will cause the screw to press more firmly upon the projection thus the
position of the roller d is more thoroughly secured.
In connection with the mechanism above described the rollers and may be
made use of for the well known purposes, or a brush may be used in place of these
oller, or two mops may be used in place of these rollers and s
r
Instead of the grooved roller s being formed by a series of annular pieces of
different sizes being mounted upon then axial shaft, this grooved roller is preferably
formed in one piece or whole
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed declare that what I
claim 18,
1 In mechanisin for cleaning kuives of the like. the combination of a vair

relatively with the other substantially as herein specified.
2. The combination in mechanism for cleaning knives of a pan of rollers, lever
arms for supporting one of said rollers, screw or other mechanism for adjusting and
securing said lever aims and gearing wheels arranged to transmit motion to said
rolleis substantially as herem set forth.
