Improvements in Roller Knife Cleaning Machines.
We, CHARLES DARRAII, of the Firm of Baxendale & Co., of Miller Street, Man-
chester, Merchant, and WILLIAM HERRIS WRIGHT, of 524, Ashton Road, Open-
shaw, Manchester, Engineer, do hereby declare the nature of our said invention
to be as follows:-'
It consists in mounting the axle of the intermediate gear wheel of a roller
knife-cleaning machine (which gives the reverse motions to the cleaning rollers)
in a curved slot or groove, formed in, or on the machine frame side, or an
extension thereof, and securing such axle therein at any desired part by nut,
collar, pin or other suitable device.
The curve of the slot is struck from the centre of the lower roller axle, so that
as the axle of the said intermediate wheel is moved along the slot its teeth
are always in complete mesh, or gear with the gear wheel of the lower roller,
and as the upper roller moves down the intermediate wheel is adapted to allow
of such movement without altering its degree of mesh with the gear wheel of the
said top roller, and thus whatever the condition of the rollers, from the full
diameter down to the bar stock or axle, the gear wheels of the rollers are always
in gear and the rollers capable of effective use until fully worn out.
The slot, instead of being set to a radius from the lower roller axle, may be
set to a radius from the upper roller axle, with the lower roller arranged to rise
against the upper roller.
As a further improvement in this class of knife-cleaning machines, we provide
the upper roller axle with an extension and fit thereon a fluted rubber or like
buff, adapted to rotate and serve for cleaning forks or shoulder parts of a knife
near the handle.

Improvements in Roller Knife Cleaning Machines.
We, CHARLES DARRAH, of the Firm of Baxendale & Co., of Miller Street, Man-
chester, Merchant, and WILLIAM HERRIS WRIGHT, of 524, Ashton Road, Open-
shaw, Engineer, do hereby declare the nature of this invention and in what

in and by the following statement:―
It consists in mounting the axle of the intermediate gear wheel of a roller
knife cleaning machine (which gives the reverse motions to the cleaning rollers)
in a curved slot or groove, formed in, or on the machine frame side, or an
extension thereof, and securing such axle therein at any desired part by nut,
collar, pin or other suitable device.
The curve of the slot is struck from the centre of the lower roller axle, so that
as the axle of the said intermediate wheel is moved along the slot its teeth
are always in complete mesh or gear with the gear wheel of the lower roller,
and as the upper roller moves down the intermediate wheel is adapted to allow
of such movement without altering its degree of mesh with the gear wheel of the
said top roller, and thus whatever the condition of the rollers, from the full
diameter down to the bar stock or axle, the gear wheels of the rollers are always
in gear and the rollers capable of effective use until fully worn out.
The slot, instead of being set to a radius from the lower roller axle, may be
set to a radius from the upper roller axle with the lower roller arranged to rise
against the upper roller.
As a further improvement in this class of knife-cleaning machine, we provide
the upper roller axle with an extension and fit thereon, a fluted rubber or like
buff, adapted to rotate and serve for cleaning forks or shoulder parts of a knife
near the handle.
On the accompanying sheet of drawings Fig. 1 illustrates an end view, and
Fig. 2 a part front view of a knife cleaning machine constructed in accordance
with our invention.
Fig. 3 illustrates a detail.
(A) designates the machine end or frame, and (B) (B*) the two cleaning
rollers. (() and ((**) the pitch lines of the two gear wheels which give motion to
the cleaning rollers, and (D) the pitch line of the intermediate gear wheel for
giving the reverse motion to the cleaning rollers.
(E) is the slot in which the stud or axle (F) on which the intermediate wheel
rotates is mounted and held by clamping nut or other suitable means at various
points in the length of the slot to suit the diameters of the cleaning rollers as
foresaid.
() is the rubber or flexible buff carried by an extension of the spindle of the
upper roller for cleaning the shoulders of knives and forks. The preferred cross-
section of the buff is shewn in Fig. 3.
l'or catching the dust from the buft we form the frame (A) with extension (A*)
formed as a well or tray.
Having thus particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:
1: In knife cleaning machines, a slot or groove in or about the side or end of
the frame in which the axle of the intermediate gear wheel may be adjustably
mounted, as and for the purposes set forth.
2: In knife cleaning machines, the combination of a flexible fluted buff
carried by an extension of the spindle of the upper roller, as and for the purposes
herein set forth.
