I WILLIAM ROBERT LAKE of the firm of Haseltine Lake & Co Patent Agents
Southampton Buildings in the County of Middlesex do hereby declare the nature
of my invention for "IMPROVEMENTS IN MACHINES FOR BENDING AND UP-SETTING
METALS OR OTHER MATERIALS" to be as follows:-
--
This invention relates to an improved machine for bending and upsetting or
jumping metals and other materials; either of the two operations can likewise be
performed at will with the said machine.
The machine, according to one modification consists chiefly of two parts one of
which is fixed and the other movable around a central point of articulation and
which I term the movable piece or jaw and the fixed piece or jaw. The movable
piece or jaw can be turned to the right or left so as to touch the fixed piece or jaw
on one side or on the other. Each of the said pieces or jaws has holes for receiving
articulated handles or levers having toothed or serrated ends forming jaws and in
the middle they have a triangular projection provided with toothed or serrated
steel plates. The movable piece or jaw is provided at its centre with a shoulder
which holds it upon the block which supports the fixed piece or jaw; but the
movable piece can turn around a central steel spindle which extends through its
entire height. This rotation of the said piece is effected through the medium of a
lever which can be inserted in apertures in the said piece. The block supporting
the fixed piece or jaw is firmly secured in such a manner that it is capable of being
adapted to serve as a vice.
When a bar of iron, for example, is to be bent, it is pressed between the said
toothed or serrated projections and the toothed or serrated ends of two of the
aforesaid handles or levers and the movable piece or jaw is turned by means of a
lever or handle. By the rotation of the movable piece or jaw the bar taken
between the jaws or projections and the aforesaid levers or handles is subjected to
a transverse strain which gives it a bent form.
.
According to another modification the machine is adapted for bending and
jumping or up-setting and is driven by a hand-wheel.
'

page_text: In this modification the two essential elements of the preceding machine viz:-
the fixed and movable pieces or jaws are likewise employed. The rotary or
movable piece is secured by hinges upon a frame in which its spindle or axis is
located. It is held by two flaps or wings of the said frame which extend towards
the centre of the apparatus.
At its lower portion the movable piece carries a foot extending beyond the round
portion of the said frame. This round portion has the form of a basin and in it is
placed a toothed bevel-wheel fixed on the spindle which serves as the axis of
rotation for the said movable piece. The said foot is provided with four holes, the
two outer of which serve for securing it to the frame by a bolt or pin which passes
through one of the said holes and through one of a series of holes in the round
portion or basin so as to fix the foot and with it the movable piece or jaw. By
reason of the multiplicity of the holes in the suid round portion or basin, the said
movable piece can be held in a great many different positions. When, on the
contrary, the requisite rotary movement is to be imparted to the said piece or jaw
in order to bend the metal, the said bolt or pin is removed and inserted in one of
an inner series of holes in the said foot. These holes correspond with a series of
holes in the aforesaid bevel gear-wheel in such a manner that the connection of the
¯said-foot-and of the movable piece with the said gear-wheel can be effected. Motion
can be transmitted to this gear-wheel by an inclined shaft, two bevel wheels, and a
fly-wheel or hand-wheel. The movable piece can thus be moved a quarter of a torn
or more in effecting the necessary rotation for bending the metal bar being operated-
upon.
The fixed piece or jaw is likewise supported by two flaps or wings of the frame
which pass-through mortises formed in the said fixed piece. This piece can slide
upon the said flaps or wings, in order-to-jump or up-set the metal. For this
purpose it is united on the one hand to a rocking-lever and on-the-other hand, to a
small lever, which are connected by slotted links. The two levers are so pivotted
upon the flaps or wings that-the-oscillatory motion of the rocking lever causes-that
of the small lever, and produces consequently the sliding-motion of the fixed piece
upon the said flaps or wings.
At its lower portion the said rocking-lever is connected with another lever by a
rod which serves to communicate to it its oscillatory movements. The last named
lever is pivotted upon the central spindle and can be moved by the aforesaid bevel
gear-wheel by uniting it therewith by means of a pin or bolt passing through a
hole in the said lever and one of the holes in the said wheel. The said lever can
moreover be fixed by removing the said pin or bolt and passing it through another
hole in the said lever and through one of the holes in the said round portion.or
basin.
The articulation of the connecting rod with the said lever can be varied by
removing a connecting pin or bolt from one of the holes and placing it in another
in such a manner that the oscillations of the said rocking lever can be rendered
more or less rapid according to the pressure which it is desired to bring to bear in
jumping or up-setting.
If the said lever is connected with the gear wheel by the pin or bolt, when this
wheel is made to turn in order to bend the metal, the rocking lever which moves in
the frame will actuate the upper portion of the fixed piece or jaw, whilst the small
lever will actuate the lower portion of the said piece, so as to cause it to slide upon
the flaps or wings and thus approach the rotating or movable pieco and thereby
effect the jumping or up-setting of the metal at the same time as the bending.
A lenticular shoulder is provided to facilitate the pushing of the fixed piece by
the upper part of the rocking lever.
All the parts of the machine are supported by the frame made in one piece with
the two flaps or wings which are provided with suitable incisions or slots for the
passage of the rocking levers which have their centres of oscillation there.
The driving of this machine, instead of being effected by gear wheels as above
described, can be effected in any other suitable manner, for instance by articulated

page_text: levers, or endless chains, placed at the upper or lower end; the fixed and movable
jaws or pieces can he made of any suitable form, and of any desired height.
It will be understood, that in order to hold the iron pieces under operation upon
the machine recourse is always had to levers or handles analogous to those first
herein described.
The fixed and movable jaws or pieces can be so arranged as to be adapted to bars
of various sections which it may be requisite to bend.
COMPLETE SPECIFICATION.
I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake and Co Patent
Agents, Southampton Buildings, in the County of Middlesex, do hereby declare
the nature of my invention for "IMPROVEMENTS IN MACHINES FOR BENDING AND
UP-SETTING METALS OR OTHER MATERIALS" 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 an improved machine for bending and jumping or
upsetting metals and other materials; either of the two operations can likewise be
performed at will with the said machine.
The construction and operation of the improved machine will be readily
understood from the following description reference being had to the accompanying
drawing in which
Figure 1 represents in elevation a machine for bending and jumping or upsetting
metals or the like and having a simple lever for operating it.
Figure 2 is a plan of the same, and
Figure 2 is a perspective view.
Figure 3 is an elevation partly in section of a machine which operates auto-
matically, and showing the driving gear.
Figure 4 is n side view partly in section and
Figure 5 a plan of the same.
Figures 6 and 7 are plan views below the lines X Y and Z Z respectively
Figure 3 the driving mechanism being supposed to be removed.
The machine constructed according to the modification represented in Figures 1
and 2 consists chiefly of two pieces A and B. one of which is fixed, and the other

page_text: movable around a central point of articulation. The movable piece A can be turned
to the right or left so as to touch the fixed piece on one side or on the other. Each
of the said pieces A and B has holes a a for receiving articulated handles or levers
CC having toothed or serrated ends forming gripers and in the middle the said
pieces have triangular projections or jaws 6 6 respectively, provided with toothed
or serrated steel plates. The movable piece A is provided with a shoulder c
concentric with its point of articulation which shoulder holds the said piece upon
the block & carrying the fixed piece B; but the movable piece A can turn around
a central steel spindle which extends through its entire height. This rotation of
the piece A is effected through the medium of a lever D which can be inserted into
apertures in the said pieco A. The jaw b' upon the fixed piece B is firmly secured
in such a manner that it is capable of being adapted to serve as part of a vice.
When a bar P say of iron is to be bent, it is placed between the said toothed or
serrated jaws b and b¹ and the toothed or serrated ends of two of the handles or
levers C C and the movable piece A is turned by means of the lever D or a handle.
By the rotation of the piece A, the bar P held between the jaws bb¹ and the
gripers on the handles CC is subjected to a transverse strain which gives it a bent
form as shown in Figures 2 and 2ª.
According to the modification shown in Figures 3 to 7 the machine is adapted
for bending and jumping or up-setting and is driven by a hand wheel.
In this modification the two essential elements of the-preceding machine viz.
the pieces A. B which carry jaws are likewise employed. The rotary, or movable-
piece A is secured by hinges upon a frame E in which its spindle or axis is located..
It is held by the two flaps or wings c c of the frame E which wings extend towards
the centre of-the-apparatus.
At its lower portion the piece A-has-a-foot M extending beyond the portion m
of the frame E. This portion has the form of a round basin-and-in-it.is_placed a
toothed bevel-wheel H fixed on the spindle which serves as the axis of rotation
for the movable piece A. The foot M is provided with four holes, (Figure 7), the
two outer of which serve for securing it to the frame-E-by a bolt or pin O which
passes through one of the said holes n n and through one of a series of holes nin
of the side of the basin so as to fix the foot and with it the moveable piece A. By
reason of the multiplicity of the holes in the said round portion or basin n¹ n¹ the
said moveable piece A can be fixed in a great many different positions. When on
the contrary the requisite rotary movement is to be imparted to the said piece A
in order to bend the metal, the said bolt or pin O is removed and inserted in one of
an inner series of holes oo in the said foot M. These bolts correspond with a series
of holes pp in the aforesaid bevel gear wheel H in such a manner that the
connection of the said foot M and of the movable piece A with the said gear wheel
can be effected. Motion can be transmitted to the gear wheel H by the inclined
shaft G the two bevel wheels g' g' and the flywheel or handwheel F. The movable
piece A can thus be moved a quarter of a turn more or less in effecting the
necessary rotation for bending the metal bar being operated upon.
The piece B is likewise supported by the two flaps or wings c c of the frame,
which wings pass through mortises formed in the said piece. This piece can be
caused to slide upon the said flaps or wings cc in order to jump or upset the metal.
For this purpose it is united to a rocking lever K and to a small lever L the
connecting pins working in slots as shown in Figure 3 of the drawing. The two
levers K and L are so pivoted upon the wings cc that the oscillatory motion of
the rocking lever K causes that of the lever L and produces consequently the
sliding motion of the piece B upon the wings c, c.
At its lower portion the rocking lever K is connected with another lever I by a
rod which serves to communicate to it its oscillatory movements. The lever I is
pivoted upon the central spindle and can be moved by the gear-wheel H by
uniting it therewith by means of a pin & passing through a hole r in the said lever I
and one of the holes p in the wheel H. The said lever I can moreover be fixed by

page_text: removing the said pin or bolt s, and passing another 8¹ through the hole r¹ in the
said lever I and through one of the holes n' in the basin m.
The articulation of the connecting rod J with the lever I can be varied by
removing the connecting pin or bolt t from one of the holes u, u, and placing it in'
another in such a manner that the oscillations of the rocking lever K can be
rendered more or less, long according to the pressure which it is desired to bring to
bear in jumping or up-setting.
If the lever I is connected with the gear wheel H by the pin or bolts when this
wheel H is made to turn in order to bend the metal, the rocking lever K which
moves in the frame 'E' will actuate the upper portion of the fixed piece B, whilst
the lever L will actuate the lower portion of the said piece, so as to cause it to
slide upon the flaps or wings cc and thus approach the rotating or movable piece A
and thereby effect the jumping or up-setting of the inetal at the same time as the
bending.
A shoulder N is provided to facilitate the pushing of the piece B by the upper
part of the rocking lever K.
All the parts of the machine are supported by the frame E made in one piece
with the two flaps or wings cc the latter being provided with suitable incisions or
slots for the passage of the levers K and L which have their centres of oscillation
therein.
The connection of the rocking-lever K with the piece B is shown in Figure 6,
and Figure 7 shows the connection between the gear-wheel H the foot M and the
lever I which produce respectively the rotating movement of the piece A and the
sliding movement of the piece B for jumping or upsetting.
The driving of this machine instead of being effected by gear wheels as above
described can be effected in any other suitable manner for instance by articulated
levers, or endless chains, placed at the upper or lower end. The jaws or gripers
carried by the fixed and movable pieces A and B can be made of any suitable
form and of any desired height.
It will be understood that in order to hold the iron pieces under operation upon
the machine represented in Figures 3 to 7 recourse is always had to levers or
handles C analogous to those herein described with reference to Figures 1 and 2.
The jaws carried by the pieces A and B can be so arranged as to be adapted to
bars of various sections which it may be requisite to bend.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed as communicated to
me by my foreign correspondent I declare that what I claim is
First-The machine for bending metals and other materials and characterized
essentially by the combination of two toothed or serrated jaws with gripers having
levers, between which jaws and gripers the metal to be bent is held, one of the
said jaws being fixed whilst the other is capable of receiving a movement around
a central pivot which movement can be communicated to it by hand, either by
means of a lever as shown in Figures 1 and 2 of the drawing, or by any other
suitablo mechanism.
Second: A machine for bending and jumping or upsetting metals and other
materials, consisting essentially of two toothed jaws combined with gripers for
holding the material being operated upon, the bending being effected by the
rotation of one of the jaws around a central pivot, the other jaw effecting simul.
taneously the jumping or upsetting of the material by a sliding motion which is
imparted to it by the piece to which the movable jaw is attached.
Third: The machine for bending and jumping or upsetting metals and other
materials, having the actuating mechanism, represented in Figures 3 to 7 of the
drawing, which mechanism can transmit rotary motion to the toothed movable
jaw for effecting bending, by connecting the said jaw, by a pin with a foot
connected with this jaw; and a sliding motion to the second jaw for effecting the

page_text: jumping or upsetting of the material by connecting the latter jaw with a lever
transmitting oscillating motion through a suitable connecting rod to two rocking-
levers united with the upper and lower parts of this jaw in such a manner as to
cause it to approach the rotary jaw in parallelism therewith.
Fourth-Effecting separately either of the two operations of bending or jumping.
or upsetting by rendering either the foot which is connected with the toothed
movable jaw, or the lever actuating the rocking levers imparting sliding motion to
the second jaw independent of the motion of the actuating mechanism of the
machine the said foot and actuating lever permitting of being connected at will by
means of pins with the fixed frame of the machine, as described with reference to
Figures 3 to 7 of the drawing.
