Improvements in and relating to Machines for Rolling Knife and
Fork Blanks.
I, JOSEPH NATHANIEL NUTT, of 3, Market Place, Derby, in the County of
Derby, Secretary to Charles Peach & Co., Limited, do hereby declare the nature
of this invention to be as follows:-
This invention relates to rolling machines and particularly to those adapted
for rolling knife blanks to form the blade thereof after the bolster has been
previously formed in another machine or machines.
Where knife and fork blanks are to be so shaped as to be suitable for grinding
or finishing in automatic machines, it is quite desirable and in fact almost
essential to the production of a high class of such articles to have the blanks as
uniform and as near the ultimate finished form and contour of the article as it
is possible to produce them. This is requisite, mainly from the fact that in
many instances the blank constitutes its own form, it being merely proportion-
ately reduced in its dimensions during the finishing steps. It follows that the
more accurately knife blanks are rolled and hence the less the grinding required
in the finishing thereof, the less will be the labour and expense of finishing
and the more uniform will be the article produced. Furthermore, the less the
amount of metal required to be removed by grinding the more superior will be
the product, for the reason that the metal of the blade is most refined (by the
rolling or forging) at or near the surface, gradually deteriorating in quality
towards the centre; hence the deeper into the metal it is necessary to grind to
bring the blade to its final form the poorer will be the quality of metal left to
constitute the same.
The object of my present invention is, therefore, to provide a machine for
rolling knife blades to proper form, that is to say, the back edge of the blade
tapering from the thickest part at the handle to the point and the cutting edge
being of substantially uniform thickness throughout-whereby the objects above
referred to may be more perfectly accomplished than in any machine now known
to me.
etc.
In a machine constructed in accordance with this invention, the blank is pre-
ferably passed successively between two or more sets of dies mounted on suit-
able rolls, the first set acting to effect a considerable flattening of the stock from
which the blade is to be formed, while the second set or finishing dies complete
the rolling and impart to the. blade its proper form-as to thickness, convexity
By thus employing a double instead of a single rolling, the blade is more
accurately formed, the metal thereof is left in a smoother and more refined
condition, and little, if any grinding is required in finishing the blade, the
whitening or glazing operations in many instances effecting all the reduction
necessary. Furthermore, by causing the first set of dies to effect the greatest
fattening of the stock and leaving the second and more accurately ground dies

page_text: the lighter work of shaping the blade, not only is wear generally greatly
reduced, but what wear there is, is mostly imposed upon the dies that are most
casily and cheaply ground.
Other important features of the machine are the holder and carrier for the
knife and the mechanism for imparting the necessary movements thereto
whereby the blank is presented to the dies in such position that they close against
the stock from which the blade is to be formed at a point adjacent to the bolster
and as the rolling proceeds the holder is advanced by the action of the dies or
by suitable mechanism for that purpose, or by both. After the first set of dies
have passed over and released the blank the holder is moved laterally far enough
to bring the blank in line with the second set of dies and then forwardly to
present the blank to said dies which act to complete the rolling of the blade.
After the second set of dies have released the blade, the holder is given a
return movement during which it is opened by a trip, allowing the blank to drop
out and finally coming to rest at its starting position with its jaws held partly
open to receive another blank.
Upon the forward movement of the holder the jaws are automatically closed by
the action of a suitable spring and the blank held tightly in the holder while
being presented to the action of the dies.
The mechanism for imparting the movements above referred to, to the holder,
is automatically arrested after one revolution and remains at rest until again
started by the attendant.
Other novel features of the construction, as well as those already referred to.
will be more particularly described hereinafter.
In carrying out my invention I provide rolls bearing in suitable standards
mounted on a base.
Said rolls are geared together at one end by pinions and power is communi-
cated thereto from any suitable source to an extended end of the shaft of the
lower roll.
Two sets of dies are set in pockets or recesses in the rolls and rest against wedge
shaped blocks in the bottom of said pockets. These blocks may be moved by
screws to adjust the dies, to take up wear, or to the required thickness of the
blade to be rolled. As another or secondary means for effecting adjustment of
the dies, a number of plates or liners may be interposed between the inner end
of one of the dies and the wedge block or the wedge block may be omitted and
liners only used.
For retaining the dies proper position in the pockets, I employ wedges driven
in tight or otherwise secured. Of the two sets of dies above referred to, the
acting surfaces of the first set are of such contour as to partially flatten the
stock of which the blade is to be formed, while the acting surfaces of the second
set are of such contour as to complete the rolling and shaping of the partially
flattened blade.
The devices for holding the knife and presenting the same to the action of the
rolls will next be explained.
A U-shaped carrier is arranged to slide in suitable ways on the sides of the
standards already mentioned when reciprocated by the means hereinafter
described, an auxiliary U-shaped carrier is adapted to slide in suitable openings
in the side-bars of the first named carrier when reciprocated by means hereafter
described. The knife holder is mounted on the auxiliary carrier and consists of
two sleeves, one of which (carrying two stationary jaws against which the blank
is gripped) being secured to the auxiliary carrier while the other (carrying two
movable jaws for gripping the blank) is free to rotate on the side bar of the
auxiliary carrier against the tension of a coiled spring; a cross bar formed
integral with the first mentioned sleeve rigidly connects the latter with the side-
bar or the opposite side of the auxiliary carrier. A projection at one side of the
cross-bar and an arm on the opposite end of the first mentioned sleeve from the
cross-bar, constitute the stationary or fixed jaws against which the handle is

page_text: gripped by two arms projecting from the other sleeve and constituting the
movable jaws.
A lug or projection extending upwardly and formed integral
with the sleeve last mentioned and one of the arms is adapted to make contact
(on the lateral return movement of the work-holder), first, with the extreme
point of a fixed projection on one of the standards and secondly, with a
shoulder or tooth on the said projection, against which it rests to hold the
movable jaws in a partially open position when the carrier is at its starting
position, as will be more fully hereinafter explained. The desired movements
are imparted to the carriers from the axle of the lower roll, through a small
gear and a large gear turning loosely on a stud or shaft rigidly secured to one of
the standards.
A drum is also loosely mounted on the said shaft and has a double cam secured
to one end adjacent to the large gear. The peripheral surface of the drum is
formed with a cam groove and with a straight groove in which engages a spring
actuated latch inclined at opposite edges, sliding in a bracket.
When the operative parts of the machine are in a state of rest the latch rests
in front of a shoulder on a spring actuated pin sliding in a suitable chamber in
the drum, thereby holding the said pin out of engagement with one of a series
of recesses in the inner face of the rotating gear. A treadle lever is connected
with the lower end of the latch by a link so that upon the depression of the said
lever the latch releases the pin which drops into one of the recesses of the
large gear and causes the drum to be carried around with said gear until it has
made a complete rotation, when the inclined edge of the latch engages behind a
shoulder on the pin, withdrawing the latter from engagement with the gear and
bringing the drum to rest, in which position it is retained until the treadle lever
is again operated. The latch being inclined on both edges acts to withdraw the
pins in which ever direction the drum is rotated.
For reciprocating the first named U-shaped carrier a rock-shaft bearing in
suitable ears on the base, carries at opposite ends two levers, pivoted to the side
bars of the carrier frame and one of the said levers having a roller thereon pro-
jecting into the cam groove of the drum whereby reciprocation in opposite
directions is imparted to said frame upon each complete rotation of the drum.
For reciprocating the auxiliary carrier another rock-shaft having levers at
opposite ends, one of which has a forked extension embracing the frame of the
carrier, the other lever carrying a friction roller against which a cam bears to
rock the last named lever and reciprocate the carrier in one direction, said
carrier being moved in the opposite direction by the action of the rolls drawing
the knife there between and by the tension of a spring, secured at one end to
one of the standards and at the other end connecting a pin on the said rock
shaft.
The operation of the machine is as follows:-
The cam operating through levers and rock-shaft having forced the auxiliary
carrier to the limit of its rearward movement the bite of the dies is closing
against the partially flattened part of the blank adjacent to the bolster. The
further movements of the parts cause one of the highest points of the cam to
pass the roller on one of the levers at which instant the dies close against and
begin their action on the knife blank, and of course, move the latter and auxiliary
carrier forward. After the blank is released from the bite of the rolls, the spring
acts to continue the advance of the carrier until the roller again comes into
contact with cam. One of the inclined parts of the cam groove now comes
into action to move the carrier to the left, so as to bring the partially rolled
blank into line with the second set of dies. The cam again comes into action
and returns the auxiliary carrier to the limit of its rearward movement, at which
instant the dies close against and complete the rolling and shaping of the blade.
After the blade is released from the bite of the second set of dies the spring
again comes into action to advance the auxiliary carrier to the limit of its for-
ward movement when the second incline in the cam groove acts to return the

page_text: carrier to its starting position by shifting it to the right, during which latter
movement a lug on the sleeve of the holder strikes the extreme point of the
fixed projection on one of the standards with which it is now in line, lowering
the movable jaws against the tension of the coiled spring and automatically dis-
charging the blank from the holder. As the carrier moves still further, the lug
slips off the extreme point of the projection and by action of the coiled spring is
brought into contact with the shoulder of the projection partially closing the
movable jaws, the stationary and movable jaws being in this position far enough
apart to permit of the introduction of a new blank there-between.
When the parts have arrived at the position last referred to, the pin is with-
drawn from engagement with the gear by the action of the inclined edge of the
latch as already described (the drum and cam having made a complete rotation)
A new blank is now
and the operation of the feeding mechanism is arrested.
introduced into the holder and the lever again actuated to start the operation of
the work-holder. As the auxiliary carrier moves rearwardly, the lug slips off the
shoulder and the jaws close tightly against the blank. The operation already
described is now repeated.
From the foregoing description it will be understood that the entire operation
of the machine, after the insertion of the blank and the manipulation of the
starting lever is automatic and requires the attention of an operator of but
ordinary skill and experience.
In rolling-blades for knives whereof the handle is made separate from the
blade, a double blank, may be employed adapted to be severed at the centre and
suitably formed for attachment of handles to the blades.
In rolling such a blank, one end offers a suitable part to be gripped by the
holder while the part at the other end is being rolled."
After one blade is rolled the blank may be reversed in the holder to roll the
other blade.
Modifications of and departures from the precise construction herein described
and illustrated may, of course, be made without departing from the principle of
my invention.
It will also be apparent that any desired number of sets of dies may be
employed, as for example, in rolling small knife blades one rolling is sometimes
sufficient in which case only one set of dies would be necessary, whereas, in other
instances it may be expedient and desirable to employ three or even more sets
of dies.

COMPLETE SPECIFICATION.
Improvements in and relating to Machines for Rolling Knife and
Fork Blanks.
I, JOSEPH NATHANIEL NUTT, of 3, Market Place, Derby, in the County of
Derby, Secretary to Charles Peach & Co., Ltd., 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 relates to rolling machines and particularly to those adapted
for rolling knife, fork and other blanks such as plane irons chisels and the like,
to form the blade thereof after the bolster has been previously formed in another
machine or machines.

page_text: Where knife fork and other blanks are to be so shaped as to be suitable for
grinding or finishing in automatic machines, it is quite desirable and in fact
almost essential to the production of a high class of such articles to have the

that in many instances the blank constitutes its own form, it being merely pro-
portionately reduced in its dimensions during the finishing steps. It follows
that the more accurately knife blanks are rolled and hence the less the grinding
required in the finishing thereof, the less will be the labour and expense of finish-
ing and the more uniform will be the article produced. Furthermore, the less
the amount of metal required to be removed by grinding the more superior will
be the product, for the reason that the metal of the blade is most refined (by the
rolling or forging) at or near the surface, gradually deteriorating in quality
towards the centre; hence the deeper into the metal it is necessary to grind to
bring the blade or blank to its final form the poorer will be the quality of metal
left to constitute the same.
The object of my present invention is, therefore, to provide a machine for
rolling knife fork and other blanks or blades to proper form-that is to say,
for example the back edge of the blade of a knife tapering from the thickest
part at the handle to the point, and the cutting edge being of substantially uni-
form thickness throughout-whereby the objects above referred to may be more
perfectly accomplished than in any machine now known to me.
In a machine constructed in accordance with this invention the blank is pre-
ferably passed, successively between two or more sets of dies mounted on suit-
able rolls the first set acting to effect a considerable flattening of the stock from
which the blade of a knife is to be formed, while the second set or finishing
dies complete the rolling and impart to the blade its proper form as to thick-
ness, convexity, etc. By thus employing a double instead of a single rolling the
blank is more accurately formed, the metal thereof is left in a smoother and
more refined condition, and little, if any, grinding is required in finishing the
blade, the whitening or glazing operations in many instances effecting all the
reduction necessary. Furthermore, by causing the first set of dies to effect the
greatest flattening of the stock and leaving to the second and more accurately
ground dies the lighter work of shaping the blade, not only is wear generally
greatly reduced, but what wear there is is mostly imposed upon the dies that are
most easily and cheaply ground.
Other important features of the machine are the holder and carrier for the
knife, and the mechanism for imparting the necessary movements thereto,
whereby the blank is presented to the dies in such position that they close against
the stock from which the blade is to be formed at a point adjacent to the
bolster, and as the rolling proceeds the holder is advanced by the
action of the dies, or by suitable mechanism for that purpose, or
by both.
After the first set of dies have passed over and released the
blank, the holder is moved laterally far enough to bring the blank in line
with the second set of dies, and then forwardly to present the blank to said dies
which act to complete the rolling of the blade. After the second set of dies have
released the blade, the holder is given a return movement during which it is
opened by a trip, allowing the blank to drop out, and finally, coming to rest
at its starting position with its jaws held partly open to receive another blank.
Upon the forward movement of the holder the jaws are automatically closed by
the action of a suitable spring, and the blank held tightly in the holder while
being presented to the action of the dies. The mechanism for imparting the
movements above referred to to the holder is automatically arrested after one
revolution and remains at rest until again started by the attendant.
Other novel features of the construction, as well as those already referred to,
will be more fully understood by reference to the accomplished drawings form-
ing part of this specification, wherein: -

page_text: Figure is a horizontal section taken between the rolls..
Figure 3 is a vertical sectional view on line 1-2; Figures 1 and 2.
Figure 4 is an elevation from the right of Fig. 2.
Figure 5 is a detail plan view of the holder for the knife-blank or stock
which is shewn in place therein.
Figure is a sectional view on line 6, Fig. 5, shewing also a stop or projection
which is fixed on the frame of the machine as shewn in other figures."
Figure 7 is a sectional view on line 7 of Fig. 5.
Figure 8 is a sectional view on line 8, Fig. 5, the knife blank being shewn in
elevation, and
Figure 9 is a detail view of a double blank such as may be used in rolling
blades for knives the handles of which are made separate from the blade.
Referring to the drawings, A A represent the rolls bearing in standards BB,
mounted on base C. Said rolls are geared together at one end by pinions a, a
and power is communicated thereto from any suitable source to the extended
end of the shaft of the lower roll. dd, d, are two sets of dies set in pockets
or recesses in rolls A A (see Fig. 3) and resting against wedge shaped blocks
in the bottom of said pockets. Blocks & may be moved by screws to adjust
the dies, to take up wear, or to the required thickness of the blade to be rolled.
As another or secondary means for effecting adjustment of the dies, a number of
plates or liners may be interposed between the inner end of one of the dies d' d
and the wedge block or the wedge block may be omitted and the liners only
used. For retaining the dies in proper position in the pockets I employ
wedges driven in tight or otherwise secured. Of the two sets of dies above
referred to, the acting surfaces of the first set are of such contour as to partially
Hatten the stock of which the blade is to be formed, while the acting surfaces
of the second set are of such contour as to complete the rolling and shaping of
the partially flattened blade.
The devices for holding the knife and presenting the same to the action of
the rolls will next be explained. Referring particularly to Figures 2 and 3,
E is a U-shaped carrier adapted to slide in suitable ways ce on the sides of
standards BB when reciprocated by means hereinafter described.
Fis an
auxiliary U-shaped carrier adapted to slide in suitable openings in the side-
bars of frame E when reciprocated by means hereafter described. The knife
holder is mounted on the auxiliary carrier F and consists of two sleeves gg',
sleeve (carrying two stationary jaws against which the blank is gripped) being
secured to the auxiliary carrier, while sleeve gl (carrying two movable jaws for
gripping the blank) is free to rotate on the side bar of auxiliary carrier Fagainst
the tension of a coiled spring h. Cross-bar ', formed integral with sleeve g,
rigidly connects the latter with the side-bar on the opposite side of the auxiliary
carrier. A projection 2 at one side of cross-bar h', and an arm i on the opposite
end of sleeve g from the cross-bar, constitute the stationary or fixed jaws against
which the handle is gripped by the arms projecting from sleeve gl and con-
stituting the movable jaws. A lug or projection 7 extending upwardly and
formed integral with sleeve g₁ and arm is adapted to make contact (on the
lateral return movements of. the work-holder), first, with the extreme point of a
fixed projection m (see Fig. 6) on one of the standards B (see Fig. 2), and
secondly, with a shoulder or tooth m¹ on said projection, against which it rests
to hold the movable jaws in a partially open position when the carrier is at its
starting position, as will be more fully hereinafter explained.
The desired movements are imparted to the carriers E and F from the axle of
the lower roll A through a small gear n, and a large gear N turning loosely on a
stud or shaft o rigidly secured to one of the standards B (see Fig. 1). A drum p
is also loosely mounted on shaft o and has secured to one end adjacent to gear N
a double cam g. The peripheral surface of drum P is formed with
cam groove p¹ and with a straight groove 23 in which engages
a

page_text: a spring actuated latch r inclined at opposite edges (see dotted lines
Fig. 2) and sliding in a bracket r When the operative parts of the
machine are in a state of rest the latch rests in front of a shoulder s¹ on a
spring actuated pins sliding in a suitable chamber in drum p, thereby holding
said pin out of engagement with one of a series of recesses n' in the inner face of
the rotating gear N. A treadle lever T (see Fig. 4) is connected with the lower
end of latch r by a link t, so that upon the depression of said lever the latch »
releases the pins which drops into one of the recesses n¹ of gear N and causes the
drum to be carried around with said gear until it has made a complete rotation,
when the inclined edge of latch r engages behind shoulder s on pin s, with-
drawing the latter from engagement with gear N and bringing the drum to rest
in the position shewn in Fig. 1, in which position it is retained until treadle
lever Tis again operated. The latch being inclined on both edges acts to
withdraw pin
s in whichever direction the drum is rotated.
For reciprocating carrier E a rock-shaft U bearing in suitable ears uu on
base C carries at opposite ends two levers ulu pivotted to the side bars of frame E
at ²² and one of said levers having a roller 3 thereon (sce dotted lines Fig. 4)
projecting into cam groove 1 of drum whereby reciprocation in opposite
directions is imparted to said frame upon each complete rotation of the drum.
For reciprocating carrier F, rock-shaft V is employed having levers vat
opposite ends, lever having a forked extension embracing frame F and lever v
carrying a friction roller against which the cam bears to rock lever and
reciprocate frame F in one direction, said frame being moved in the opposite
direction by the action of the rolls drawing the knife therebetween, and by
the tension of a spring W, secured at one end to one of the standards BB and
at the other end connecting to a pin won shaft V.
The operation of the machine is as follows:
As shewn in Figures 3 and 4 the cam operating through lever », shaft V,
and lever, has forced the auxiliary carrier F to the limit of its rearward move-
ment (assuming the front of the machine to be to the right in Figs. 3 and 4)
and the bite of the dies dd is closing against the partially flattened part of the
blank adiacent to the holster. The further movement of the parts from the
position shewn causes one of the highest points of cam g to pass the roller on
lever, at which instant the dies close against and begin their action on the
knife blank, and, of course, move the latter and auxiliary carrier F forward.
After the blank is released from the bite of the rolls the spring W acts to con-
tinue the advance of the carrier until roller again comes into contact with
cam . One of the inclined parts of the cam groove now comes into action to
move carrier E to the left, Figs. 1 and 2, so as to bring the partially rolled blank
into line with the second set of dies. The cam again comes into action
and returns the auxiliary carrier F to the limit of its rearward movement, at
which instant the dies close against and complete the rolling and shaping
of the blade. After the blade is released from the bite of the second set of dies
the spring W again comes into action to advance carrier F to the limit of its
forward movement, when the second incline in cam groove pl acts to return
carrier E to its starting position by shifting it to the right (Figs. 1 and 2),
during which latter movement lug 7 on sleeve a¹ of the holder strikes the extreme
point of the fixed projection m (sec particularly Fig. 6) with which it is now in
line, lowering the movable jaws against the tension of spring to the
position shewn by dotted lines in Fig. 6, and automatically discharging the
blank from the holder.
As the carrier E moves still further the lug slips off of the extreme point
of projection m and by the action of spring his brought into contact with
shoulder m of projection m, partially closing the movable jaws to the position
shewn by dotted lines y. Fig. 6. the stationary and movable jaws being in this
position far enough apart to permit of the introduction of a new blank there-
between. When the parts have arrived at the position last referred to, the

page_text: pins is withdrawn from engagement with gear N, by the action of the inclined
edge of latch r, as already described (the drum p and cam q having made a com-
plete rotation) and the operation of the feeding mechanism is arrested. A new
blank is now introduced into the holder and the lever T again actuated to start
the operation of the work-holder. As the auxiliary carrier moves rearwardly,
projection slips off of shoulder m³ (Fig. 6), and the jaws close tightly
against the blank, as shewn in full lines in Fig. 6. The operation already
described is now repeated.
From the foregoing description it will be understood that the entire operation
of the machine, after the insertion of the blank and the manipulation of the
starting lever T, is automatic, and requires the attention of an operator of but
ordinary skill and experience.
In rolling blades for knives whereof the handle is made separate from the
blade, a double blank such as that shewn in Fig. 9 may be employed, whereof 3, 3
are the parts to be rolled into blades, 4, 4 are bolsters connected by the parts 5, 5,
which latter are adapted to be severed at 6 and suitably formed for attachment of
handles to the blades. In rolling such a blank one end offers a suitable part to
be gripped by the holder while the part 3 at the other end is being rolled.
After one blade is rolled the blank may be reversed in the holder to roll the other
blade.
Modifications of and departures from the precise construction herein described
and illustrated may, of course, be made without departing from the principle of
my invention and although the said invention is more particularly herein
described as relating to knife blanks it is evident that by employing different
dies the invention may be used for rolling fork and other blanks, such as plane
irons chisels and the like.
It will also be apparent that any desired number of sets of dies may be
employed, as for example, in rolling small knife blades one rolling is sometimes
sufficient in which case only one set of dies would be necessary, whereas in other
instances it may be expedient and desirable to employ three or even more sets
of dies.
