of Lancaster, Machinery Agent, for an Invention of "IMPROVEMENTS IN
KNIFE-CLEANING MACHINES, PART OF WHICH IMPROVEMENTS ARE APPLICABLE
PROVISIONAL SPECIFICATION left by the said Edward Martin Knight
at the Office of the Commissioners of Patents on the 9th January 1882.
EDWARD MARTIN KNIGUT of Manchester in the County of Lancaster, Machinery
Agent. "IMPROVEMENTS IN KNIFE CLEANING MACHINES PART OF
IMPROVEMENTS ARE APPLICABLE TO WRINGING AND MANGLING MACHINES."
WHICH
This Invention relates to improvements in knife cleaning machines having rollers
of india rubber whereby the use of springs, weights or adjusting screws is rendered
unnecessary and dispensed with and in wringing machines having india rubber
rollers the springs and weights are unnecessary where the rollers of wringing or
mangling machines are composed of wood, the improvements herein referred to
prevent any straining of the axles, by means of the adjusting screws, springs or
weights, applied and used in connection therewith and to an improved construction
of roller and brush for sharpening the blades and cleaning the shoulders of knives
and the prongs of forks.
In the construction of knife cleaning machines according to this my said Inven-
tion I dispense with springs, weights or adjusting screws by the use of bearings, or
steps so constructed as to be rigid, the elasticity of the india rubber rollers being
sufficient to admit the blade, and exert the necessary grip or bite thereon.
In wringing machines having india rubber rollers the rigid bearings for the axles
as above described render the use of springs or weights unnecessary.
The roller for sharpening the blades of knives and for cleaning the shoulders
thereof and for cleaning the prongs of forks consist of a roller one portion of the
length of which is covered with emery another portion is covered with india rubber
and the remaining length consists of a cylindrical brush the axis of which is geared
with the wheels of one of the main rollers and receives thereby a high rate of
rotation.
Where wood rollers are used the bearings are so constructed, that the upper one
may be raised but cannot be depressed below a point at which the rollers will be
in contact, thereby preventing any undue strain being placed upon the axles of the
rollers by the use of the adjusting screws springs or weights.

EDWARD MARTIN KNIGHT of Manchester in the County of Lancaster, Machinery
Agent. IMPROVEMENTS IN KNIFE CLEANING MACHINES, PART OF
IMPROVEMENTS ARE APPLICABLE TO WRINGING AND MANGLING MACHINES."
WHICH
This Invention relates to improvements in knife cleaning machines (having
rollers of india rubber) whereby the use of springs, weights or adjusting screws is
rendered unnecessary and dispensed with. To an improvod construction of roller
and brush for sharpening the blades and cleaning the shoulders of knifes and the
prongs of forks. Where the rollers of wringing or mangling machines are composed
of wood the improvements first herein referred to prevent any straining of the
axles by means of the adjusting screws springs or weights applied and used in
connection therewith. In the construction of knife cleaning machines according to
this my said Invention I dispense with springs weights or adjusting screws by the
use of bearings or steps so constructed as to be rigid the elasticity of the india
rubber rollers, being sufficient to admit the blade and exert the necessary grip or
bite thereon. The roller and brush for sharpening the blades of knifes and for
cleaning the shoulders thereof and for cleaning the prongs of forks consist of a
roller one portion of the length of which is covered with emery another portion is
covered with india rubber and the remaining length consists of a cylindrical brush,
the axis of which is geared with the wheels of one of the main rollers and receives
thereby a high rate of rotation. In wringing machines having india rubber rollers
the rigid bearings for the axles as above described render the use of springs or
weights unnecessary.
Where for wringing and mangling machines wood or nonelastic rollers are used
the bearings of the top roller are so constructed as to rest upon the bearing or
frame of the bottom roller soon as the rollers are in actual contact, thereby to prevent
undue strain being put upon the axles or shafts of the rollers, by the improper use
of the adjusting screw springs or weights.
Such being the nature and object of this my said Invention I will now proceed
to describe the same in detail and in order that the Invention may be fully under-
stood I have hereunto annexed 2 Sheets of Drawings illustrative thereof and have
marked the same with figures and letters of reference like figures denoting like
parts.
DESCRIPTION OF THE DRAWINGS.
Fig 1 is an elevation of the framing and rollers bearing blocks being in section-
Fig 2 is a plan view with right hand cap of bearing removed-Fig: 3 is a left
band end elevation shewing bearing blocks and axles of rollers therein-Fig: 4 is
opposite end elevation shewing gearing-Figs. 5 & 6 are elevations and plan of
bearing block detached-Fig: 7 is a front elevation partly in section of improve-
ments applied to wringing and mangling machines-Fig: 8 is end elevation of Fig: 7.
Figs. 9 and 9a are elevations shewing wherein the shaft of bottom roller is passed
through framing of machine the bearing of top roller when both rollers are in
contact rests in the frame-The above Figures 1 to 95 inclusive relate to the first
part of the Invention-Figs. 10. 11 and 12 relate to the second part of the Inven-
tion Figs. 10 and 11 are elevation and plan of top polishing roller the emery wheel
and cleaning brush being in section the right hand bearing in section and the left
hand bearing in elevation-Fig: 12 is an end elevation shewing rest for blade
of knife when sharpening.

page_text: A is the framework of the machine, B the top polishing roller, C the bottom
polishing roller. D D are bearing blocks the axle of the top roller is passed through
the holes E, E, the axle of the bottom roller rests in the hollows F, F of the frame
and is held down by the concave part of the bearing D at G. G the bearing blocks
D. D are received between the upright parts H. H of the frame A over the wholo
is the cap J, J, having holding screws K. K, the cavity G and bottom of bearing
blocks aro filed until the top roller B touches and slightly bears on the lower roller
C the cap J securing the whole in position-In practice it is found, that elasticity
of the india rubber rollers is sufficient to compensate for variation in thickness of
knife blades, without screw adjustment, or springs applied to the bearing blocks-
At Figs. 7, 8 and 9 is shewn application of rigid or solid bearings D. D to a wringing
or mangling machine-At A is the frame-B the top roller-C the bottom roller-
D. D the bearing blocks-these at their lower ends partially encircle the axle of
the bottom roller C-and rest upon the lower bearing F' or upon the frame at A¹,
Bo that no sooner is the top roller in actual contact with the bottom roller than
the bearing blocks D. D. rest upon the lower bearings F¹ or upon the end frame A¹
thus giving the top roller an independent bearing and preventing any strain being
put upon its axle by the screw or weights when the rollers are not in actual use
and so obviate the principal cause of roller shafts being strained or broken-the
breakage of the gear wheels and damage and undue wear and tear of the wheels.
Referring now to Figs. 10. 11 and 12 which illustrate the second part of the
Invention B is the top india rubber polishing roller. L is the emery wheel mounted.
in cast iron pulley M on axle of roller B-at N. N are notches in cap J which
form a rest for the back of the blade when sharpening cutting edge on emery
wheel L-at P is the brush for cleaning grooves, or ornamental part of bolster or
shoulder of knife, the bristles of brush P are affixed in the circular wooden block
R and the latter driven tight or otherwise fixed on the axle of roller B.
Having thus fully described the nature and particulars of this my said Invention
together with the manner in which the same to be performed or carried
into practical effect I would have it understood that what I claim as my
Invention is.
Firstly. The construction and arrangement of bearings for axles or shafts of
machines herein referred to in manner described and for purposes set forth.
Secondly. The construction and use of india rubber roller B emery roller L
cleaning brush P combined and on one axis as illustrated and for the purposes
herein fully described.
In witness whereof I the said Edward Martin Knight havo hereunto set
my hand and seal this Sixth day of July in the year of our Lord One
thousand eight hundred and eighty two.
EDWARD MARTIN KNIGHT.
