Improvements in Machines for Sharpening Razors, and for like
purposes.
We, GEORGE NEWNES, of Wildcroft, Putney Heath, in the County of Surrey,
Member of Parliament, and WILLIAM ALLAN, of 19 Burdett Road, Bow,
London E. Fitter, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to the manner in which we construct and arrange
machines for sharpening razors, knives, and other like purposes, the object of the
invention being to produce a machine which shall sharpen both edges of the knife
or razor at once in a regular and uniform manner.
In carrying our invention into effect we construct a machine having a pair of
horizontal rollers revolving in bearings mounted or carried in the uprights or
standards of the frame of our machine, these rollers being arranged to run in
opposite directions and to have their motion communicated from one to the other by
means of gearing wheels carried on the end of the spindle of the rollers, one
spindle being arranged to receive a handle for setting the pair of rolls in motion.
We make one of the rolls to rise and fall by means of a screw carried upon the
frame or crosspiece which is mounted above the upper roll and which is connected
to the bearings or spindle of the machine so as to cause the whole roller with its
bearings to rise and fall in a regular manner when the screw is rotated by means of
a nut, thumb piece or wheel which we mount upon the outward end of the screw.
We tie the two standards or side frames of our machine together by means of a top
cross girder piece or stretcher bar which forms not only the junction piece for the
two side frames but serves as a nut for permitting the roller screw to pass through
the end wheel of manipulating end of the screw, being outside and above this top
stretcher plate or tie member.
We attach the plate to the two side frames by means of rivets, screws or pins,
or we make lugs upon the plate to enter recesses or channels formed in the side
frames such that when placed in position the whole is keyed together and secured
as one rigid piece.
We make the bearings of our machine for the shafts or spindles of the rollers
in any well known manner, providing suitable recesses or channels within the frames
for such blocks to fit into when so desired, or we may make the bottom bearing
for the lower spindle to be formed in the framework of the machine itself, while
the upper bearing alone is a movable one within the framework.
We place a table from one side to the other of our machine for receiving a clamp
plate into which the razor or implement which is to be ground can be placed and
then secured to this plate or table with its edge or cutting surface placed between
the two rollers. We make our clamp plate to be attached to the table or cross
plate of the machine by means of screws with thumb nuts or other fastenings
arranged in slots or channels formed in the table to permit of easy adjustment
being effected, and we make the clamp plate with a springing surface and of such a
form required to suit the razor which is to be introduced, or modified in shape to

receive the knife blade or other article which may be placed therein.
the table to attach to projections formed upon our side frame by means of screws,

page_text: keys or by rivets in any ordinary manner, or we make the ends of the table dove-
tail in form to fit into corresponding dovetails or recesses provided in the projecting
bearers or lugs upon the frame of the machine.
We conveniently mount the whole upon a base plate or slab which may be of
wood or other suitable material, and when so desired we place a cover over the
whole, and we make the handle adjustable or of a folding nature for convenience
in packing, and we modify the shape of the standards, stretcher bars, gearing and
the method of raising and lowering the roller to suit any particular requirement,
sometimes placing springs upon the upper bearings in order to keep the same in
tension and to permit of a yielding being possible.
The rollers we make with their outer surfaces of leather, india-rubber or other
suitable composition, the interior being of metal, wood or other suitable material,
carrying the shafts or axle through the centre or having end projecting spindles
only instead of a continuous shaft.
We place paste or other like composition upon the circular strops or sharpening
rollers, and we make apertures or openings in the frames to permit of the razor
being readily introduced from one side or the other of the uprights on to the
clamp table.
We modify the general arrangement of the machine to suit the article which is
to be sharpened.

improvements in Machines for Sharpening Razors, and for like
purposes.
We, GEORGE NEWNES, of Wildcroft, Putney Heath, in the County of Surrey,
Member of Parliament, and WILLIAM ALLAN, of 19 Burdett Road, Bow,
London E. Fitter, 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 :-
This invention has reference to the manner in which we construct and arrange
machines for sharpening razors, knives, and other like purposes, the object of the
invention being to produce a machine which shall sharpen both edges of the knife
or razor at once in a regular and uniform manner.
In the accompanying sheet of explanatory drawings to be bereinafter
referred to
Figure 1 is a front elevation and Figure 2 an end elevation of our improved
machine, the same reference letters in each view indicating the same parts.
In carrying our invention into effect we construct a machine having a pair of
horizontal rollers such as A A' revolving in bearings mounted or carried in the
uprights or side frames of our machine, these rollers being arranged to run in
opposite directions and to have their motion communicated from one to the other
by means of gearing wheels B B' carried on one end of the spindle of the rollers,
one spindle being arranged to receive a handle such as C for setting the pair of
rolls in motion. We make one of the rolls to rise and fall by means of a screw or
screws DD' carried upon the frame or crosspiece which is mounted above the
upper roll, and so connected to the bearings or roller spindle as to cause the whole
roller with its bearings to rise and fall in a regular manner when the screws are
rotated by means of a nut, thumb piece or wheel which we mount upon the outward

page_text: end of the screws. We tie the two side frames of our machine together by means
of a top cross girder piece or stretcher bar E which forms not only the junction piece
for the two side frames but serves as a nut for permitting the roller screws to pass
through, the end wheel or manipulating end of the screw, being outside and above
this top stretcher plate or tie member. When employing two screws as D D³ we
preferably arrange them in the position shown at Figure 1.
We attach the crosshead to one side frame by means of rivets, screws, or bolts,
or we make lugs upon the plate to enter recesses or channels formed in the side
frame such that when placed in position the two parts are keyed together and
secured as one rigid piece. We preferably cast or form the crosshead in one piece
with the side frame carrying the gearing wheels as illustrated at Figure 1.
We make the bearings of our machine for the shafts or spindles of the rollers
in any well known manner, providing suitable recesses or channels within the
frames for such blocks to fit into when so desired, or we may make the bottom
bearing for the lower spindle to be formed in the framework of the machine itself,
while the upper bearing alone is a movable one within the framework.
We sometimes place a table from one side to the other of our machine for
receiving a clamp plate into which the razor or implement which is to be ground
can be placed and then secured to this plate or table with its edge or cutting
surface placed between the two rollers. We make our clamp plate to be attached
to the table or cross plate of the machine by means of screws with thumb nuts or
other fastenings arranged in slots or channels formed in the table to permit of easy
adjustment being effected, and we make the clamp plate with a springing surface
and of such a form required to suit the razor which is to be introduced, or modified
in shape to receive the knife blade or other article which may be placed therein.
But instead of a cross table for securing the clamp, we preferably hinge or pivot
the clamp to a central arm or bracket F formed upon or attached to the standard
of the machine as illustrated, a handle or lever G being provided for readily
enabling the razor or other instrument to be pressed against or withdrawn from the
rolls. When employing a table, we make it attachable to projections formed upon
the side frames, by means of screws, keys, or by rivets, in any ordinary manner,
or we make the ends of the table dovetail in form to fit into corresponding
dovetails or recesses provided in the projecting bearers or legs upon the framing of
the machine.
We conveniently mount the whole upon a base plate or slab which may be of
wood or other suitable material, or we extend the foot of the standard as illustrated,
and when desired we place a cover over the whole, and we make the handle C
adjustable or of a folding nature for convenience in packing, and we modify the
shape of the standard, stretcher bar, gearing and the method of raising and lowering
the roller to suit any particular requirement, sometimes placing springs upon the
upper bearings in order to keep the same in tension and to permit of a yielding
being possible.
The rollers we make with their outer surfaces of leather, india-rubber or other
suitable composition, the interior being of metal, wood or other suitable material,
carrying the shafts or axle through the centre or having end projecting spindles
only instead of a continuous shaft.
We place paste or other like composition upon the circular strops or sharpening
rollers, and we make apertures or openings in the frames or preferably a gap such
as H to permit of the convenient introduction of the razor or other instrument
between the rolls.
We modify the general arrangement of the machine to suit the particular article
which is to be sharpened.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
