WALTER ALFRED BARLOW, of 6, St. Paul's Churchyard, London, Patent Agent
and Engineer. "IMPROVEMENTS IN APPARATUS FOR THE PRODUCTION OF BOOT-
HEEL AND OTHER IRONS OF HORSE SHOE' FORM." A communication from
abroad by Louis Bollman and Eduard Bartunck, of Vienna, and Oswald Machaneck,
of Olmütz, both in Austria.
This Invention relates to apparatus for the production of heel irons and consists
essentially as follows:-By a peculiar feed mechanism rolled or wire like drawn
iron of suitable cross section and of a certain length is introduced into the machine,
where it is bent round, punched, bent at right angles, cut off, and finally dropped
from the press as a finished heel iron.
For the reception of the moving parts of the apparatus there are provided
standards which are firmly connected together by screw bolts. The press is put in
motion by means of a pulley which is keyed on to a shaft journalled in the
standard. Besides pulley there is a pinion fastened upon the shaft, and by a spur
wheel transfers motion to a second shaft. Fastened in the middle of this second
shaft there is an eccentric upon which rests one end of a lever provided with a roller.
By a rotation of the eccentric this lever must follow the outline of the former, and
consequently be raised at the proper moment, while its lowering is effected by a
second eccentric as will be further explained.
A shaft forming the axis of the lever which is keyed thereon and therefore
imparts the oscillating or rocking motion given to it by the eccentric. Upon the
same shaft towards the side opposite the direction of the driving pulley is fastened
a lever, whose other end is provided with a roller and rests against the lower

page_text: outline of the second eccentric. The two eccentrics are of such shape that the one
at the proper moment will move forward a slide guided in the standard and con-
nected by link piece to the lever, whilst the other during the operation of pressing
draws this slide back again. On to the extension of driving shaft towards standard
is keyed a bevil gear wheel which gears with another wheel, and so drives a cross
shaft. By means of spur wheels this motion is transferred to a second cross shaft
which has its bearings in the standard. Here it must be remarked that the
proportions of wheels are so chosen as to obtain an equal number of revolutions of
both the second shafts. On the second cross shaft on the inner side of the standard
are fastened eccentric discs, which, like the before mentioned eccentrics, give an
up and downward motion to two levers provided with rolls and fastened to a
third shaft. The first lever of these two lovers terminates in a toothed segment
which gears into a rack sliding in guides in the upper part of standard, which rack
thus gets a reciprocating motion. A lug or nose fastened on to rack serves to carry
along a slide which is guided in the same direction between the two guides in the
standard. The stroke of the rack is constant, while the stroke of the slide is
adjustable by means of a screw, the distance between it and the stationary shoulder
may be lengthened and shortened, and so the stroke of the slide be diminished or
increased. On the side of standard opposite to spur-wheel on second cross shaft and
carried upon same shaft there is a disc provided with an eccentric groove. In this
groove runs the end of a lever provided with a roller, and swinging upon a third
cross shaft which is journalled in the standard. The other end of lever terminates
in a toothed segment which gears into a spur wheel fastened on a fourth cross shaft
which is journalled in the standard. On the opposite end of said shaft a cogwheel
is fastened which gears into a cog ring. The eccentric groove is so shaped as to turn,
by means of the described connection with lever, the said cog-ring either to the
right or left at the proper moment.
On the circumference of the eccentric groove disc a nose is fastened which
strikes against a roller of a lever fastened on to a shaft, and so at the proper time
moves this lever; towards standard is fastened a fork which moves ahead a shell
provided with pin, said pin is by means of screws adjustably fastened in the shell,
and acts upon a tool (to be further described) fastened on to the stamp and serving
to drop the finished irons. The shell is moved back by a spring fastened on
the inner side of standard. For straightening the iron introduced into the machine
there is fastened onto the standard a straightening apparatus, consisting of rolls,
two stationary rolls, and one adjustable roll, similar to nail machines.
The foeding
of the iron into the machine is effected by a slide in combination with the
mechanism now to be described.
.
In the top side of said slide is fitted an adjustable plate, upon which are fastened
two pins. Two jaws, somewhat resembling a pair of tongs, are mounted upon
these pins, and on their end that is turned towards the machine they widen wedge
like to the outside, while on their inner side they are provided with file cut steel
plates. On the slide are further fastened two pins fitted with rolls, which bear
against the wedge surfaces of jaws. By means of a spiral spring fastened to
feeding slide and plate the latter is pulled backwards, thereby gently jambing the
jaws with their wedge surfaces between the rolls, thus causing these jaws to close.
This apparatus is intended to hold the iron introduced between the jaws in continual
contact with the cut steel plates.
Now if by rack the feeding slide is moved ahead the plate movably inserted into
said slide resists this motion on account of the iron being jambed in upon the same.
The greater this resistance becomes the firmer the jaws are wedged in between rolls,
and so hold the iron between the steel plates, causing the iron thus held to be
moved ahead steadily. On the slide going back the rolls which bear against the
wedge surfaces of the jaws are moved backward by this retrograde motion of the
slide, and the steel plates slide back on the rod or bar of iron that has been
introduced between them. The iron introduced by the slide tangentially to the
stamp must now be bent into proper shape, which is effected by the motion of

page_text: the cog ring, that has already been described, in combination with the peculiarly
constructed stamp. A. foot screwed on to standard is so constructed as to serve in
the first place for the reception of the stamp, and besides it carries upon its outside
the cog-ring carried upon the stamp whereon it is free to turn. The cog ring is
kept from slipping off by a disc fastened on to the foot.
The stamp and cog ring have not a common centre. The cog ring has on its
front side a flange serving for the reception of the delivering template. This
template, which must follow the motion imparted to the cog-ring, is so adjusted to
to the latter that the iron introduced into the machine will touch its lower edge.
The end of the iron to be bent must be exactly under the lug or nose screwed on
to template, which prevents a shunting of the iron in any other direction while
being bent.
The stamp is constructed as follows:-In the centre upon the disc shaped stamp
body there is a core of hardened steel fastened, whose outline corresponds to the
inner contour of the heel irons to be produced. A knee piece screwed on close
towards the edge of the stamp body principally serves as a guide for the iron on
entering, and also to hold the same while being bent. Four sinall dies fitted into
the foot of the stamp serve to make the holes in the iron after it has been bent.
For cutting off and bending the iron at right angles angular cutters are fastened in
the stamp body.
For throwing off and dropping the finished irons there is provided a plate with
pins in combination with the moving mechanism of the shell. To prevent any
waste of iron at cutting off the stamp is so arranged that the iron is first bent down
by the cutter of the upper stamp, and then by a spring fastened to the foot of the
stamp brought into its original position again. The upper or top stamp is let into
the top piece which is screwed fast onto the head of slide. In this top stamp are
fastened with screws punches and cutters as well as the stamps, which latter serve
for marking the iron. A lubricating apparatus is fastened upon the standard so as
to oil the iron to be worked before entering the machine.
This machine can be used for producing heel irons of all sizes. For this purpose
it is sufficient to adjust the stroke of the slide correspondingly, and to insert into
the machine the stamp and delivering template corresponding to the desired size.
This machine may also, by making some slight modifications, be used for making
horse shoes.

"IMPROVEMENTS IN APPARATUS FOR THE PRODUCTION OF BOOT
HEEL AND OTHER IRONS OF HORSE SHOE FORM.' A communication from
abroad by Louis Bollman and Eduard Bartunck, of Vienna, and Oswald Machaneck,
of Olmütz, both in Austria.
This Invention relates to press apparatus for the production of heel irons, and
consists essentially as follows:- By a peculiar feed mechanism rolled or wire like
drawn iron of suitable cross section, and of a certain length, is introduced into the
machine, where it is bent round, punched, bent at right angles, cut off, and finally
dropped from the press as a finished heel iron.
In order that the Invention may be well understood there is annexed hereto
three Sheets of Drawings, wherein,―
Fig. 1 represents front elevation, partly in cross section, of the mechanism.
Fig. 2, a side elevation, seen from the driving pulley; Fig. III., a plan; and Figs. 4,
5, and 6, details of the stamp, delivering templates, and a finished hoel iron.
Like letters and marks refer in all Figures to like parts.
For the reception of the moving parts of the apparatus there are provided
standards A and B, which are firmly connected together by screw bolts. The press
is put in motion by means of a pulley C, which is keyed on to a shaft D journalled
in the standard A. Besides pulley C there is a pinion E fastened upon the shaft D,
and by a spur wheel F transfers motion to a second shaft G. Fastened in the
middle of the second shaft G there is an excentric H, upon which rests one end of
a lever K provided with a roller (Fig. 2). By a rotation of the excentric H this
lever K must follow the outline of the former, and consequently be raised at the
proper moment, while its lowering is effected by a second excentric I, as will be
further explained. A shaft J forming the axis of the lever K, which is keyed
thereon and therefore imparts the oscillating or rocking motion given to it by the
excentric H to this shaft. Upon the same shaft towards the side opposite the
direction of the driving pulley is fastened a lever L, whose other end is provided
with a roller and rests against the lower outline of the second excentric I fastened
upon shaft G. The two excentrics H and I are of such shape that the one at the
proper moment will move forward a slide N guided in the standard A, and con-
nected by link piece M to the lever K, whilst the other during the operation of
pressing draws this slide back again (Figs. 2 and 3). On to the extension of
driving shaft D towards standard B is keyed a bevel gear wheel O, which gears
with another wheel P and so drives a cross shaft Q (Figs. 1 and 3). By means of
spur wheels R and S this motion is transferred to a second cross shaft T which has
its bearings in the standard B. Here it must be remarked that the proportions of
wheels are so chosen as to obtain an equal number of revolutions of both the
second shafts G and T. On the second cross shaft T on the inner side of the
standard B are fastened excentric discs W and U, which like the before mentioned
excentrics H and I give an up and downward motion to two levers X and V,
provided with rolls and v and fastened to a third shaft V. The first lever A
terminates in a toothed segment which gears into a rack a sliding in guides in the
upper part of standard B which rack thus gets a reciprocating motion (Fig. 1). A lug
or nose a¹ fastened on to rack a¹ serves to carry along a slide b, which is guided in
the same direction between the two guides in the standard B. The stroke of the
rack is constant, while the stroke of the slide is adjustable by means of a screw 64,
the distance between it and the stationary shoulder b³ may be lengthened and

page_text: l
shortened, and so the stroke of the slide be diminished or increased (Figs. 1 and 3).
On the side of standard B opposite to spur wheel S on second cross shaft, and
carried upon shaft T, there is a disc Y, provided with an excentric groove. In
this groove runs the end of a lever Z, provided with a roller z and swinging upon a
third cross shaft z' which is journalled in the standard B. Now if a rotary motion is
imparted to diso Y the lever Z must move as guided by the excentric groove u.
The other end of lever Z terminates in a toothed segment which gears into a spur
wheel K fastened on a fourth cross shaft i, which is journalled in the standard A.
On the opposite end of said shaft i a cog wheel is fastened which gears into a
cog ring m.
The excentric groove u is so shaped as to turn by means of the
described connection with its lever h the said cog ring m either to the right or left
at the proper moment (Figs. 1, 2, and 3). On the circumference of the excentric
groove disc Y a nose y is fastened, which strikes against a roller 5 of à lever 6
fastened onto a shaft 7, and so at the proper time moves this lever towards
standard A. On the said shaft 7 and back of standard A is fastened a fork 8 which
moves ahead a shell 9 provided with pin 10, and pin 10 is by means of screws
adjustably fastened in the shell 9, and acts upon a tool (to be further described,
fastened on to the stamp and serving to drop the finished irons. The shell 9 is
moved back by a spring fastened on the inner side of standard A. (Figs. 1, 2, and 3).
For straightening the iron introduced into the machine there is fastened onto the
standard B straightening apparatus, consisting of rolls, two stationary rolls h'
and h, and one adjustable roll 3, similar to nail machines. The feeding of the iron
into the machine is effected by a slide b in combination with the mechanism now
to be described.
In the top side of said slide 6 is fitted an adjustable plate g, upon which are
fastened two pins f¹. Two jaws f, somewhat resembling a pair of tongs, are
mounted upon these pins and on their end, that is, turn towards the machine, they
widen wedgelike to the outside, while on their inner side they are provided with
file cut steel plates f³. On the slide bare further fastened two pins fitted with rolls
which bear against the wedge surfaces of jaws f (Fig. 3). By means of a spiral
spring fastened to feeding slide band plate g, the latter is pulled backwards, thereby
gently jamming the jaws f with their wedge surfaces between the rolls e, thus
causing these jaws to close. This apparatus is intended to hold the iron introduced
between the jaws in continual contact with the cut steel plates f³.
Now if by rack a the feeding slide b is moved ahead, the plate g movably inserted
into said slide b resists this motion on account of the iron being jammed in upon the
sane (g). The greater this resistance becomes, the firmer the jaws fare wedged in
between rolls e, and so hold the iron between the steel plates f2, causing the iron
thus held to be moved ahead steadily. On the slide going back, the rolls which
bear against the wedge surfaces of the jaws are moved backward by this retrogrado
motion of the slide, and the steel plates f' slide back on the rod or bar of iron that
has been introduced between them. The iron introduced by the slide tangentially
to the stamp, must now be bent into proper shape, which is effected by the motion
of the cog ring m that has already been described in combination with the peculiarly
constructed stamp. A foot o secured onto standard A is so constructed as to serve
in the first place for the reception of the stamp p (Figs. 1 and 4), and besides it
carries upon its outside the cog ring m carried upon the stamp, whereon it is free
to turn. The cog ring m is kept from slipping off by a disc o¹ fastened on to the
foot o (Figs. 1 and 2).
The stamp p and cog ring m have not a common centre, though that of the
former marked 1, and that of the latter marked 2, being displaced from each other
as required, in order to bend the iron brought into the machine into horseshoe shape
(Figs. 1 and 4). The cogring m has on its front side.a flange n serving for the
reception of the delivering template q. This template q which must follow the
motion imparted: to the cog ring m is so adjusted to the latter, that the .iron
introduced into the machine will touch its lower edge. The end of the iron to.be

page_text: bent must be exactly under the lug or nose q' screwed on to template q which
prevents a shunting of the iron in any other direction while being bent.
The stamp is constructed as follows:-In the centre upon the disc shaped stamp
body p, there is a core p¹ of hardened steel fastened, whose outline corresponds to
the inner contour of the heel irons to be produced. A knee piece * screwed on
close towards the edge of the stamp body, principally serves as a guide for the iron
on entering, and also to hold the same while being bent (Fig. 4). Four small dies
,,,, fitted into the foot of the stamp, serve to make the holes in the iron
after it has been bent. For cutting off and bending the iron at right angles, the
angular cutters and are fastened in the stamp body (Fig. 4).
For throwing off and dropping the finished irons, there is provided a plate a, a,
with the pins a², a³, a³, in combination with the moving mechanism of the shell 9
(Figs. 2 and 4). To prevent any waste of iron at cutting off, the stamp is so
arranged that the iron is first bent down by the cutter of the upper stamp, and
then by a spring fastened to the foot of the stamp, brought into its original position
again. The upper or top stamp is let into the top piece s which is screwed fast on
to the head of slide N. In this top stamp are fastened punches 1, 2, 3, 4, and
the cutters and 20, as well as the stamps p, p, which latter serve for marking the
iron. A lubricating apparatus 15 is fastened upon the standard A so as to oil the
iron to be worked before entering the machine (Figs. 1 and 3).
The proceeding to produce a heel iron with this machine is as follows:-The iron
to be worked up is placed upon a cross shaped reel led through the straightening
apparatus inserted between the jaws f, and introduced into the machine in
direction B, B, as far as cutter ", and then the machine is put in motion. By
excentric W in connection with the described mechanism the slide b is moved
ahead to the length it has been previously set to, and so the material required for
one heel iron is troduced. The iron to be worked at the same time passes the
lubricator, then the guide knee screwed on to the stamp, and with its end gets
underneath the lug or nose q* fastened onto the delivery template. This delivering
template moved by the mechanism acting upon cog ring m makes a rotary motion,
thus bending the iron around the core of the stamp. During this operation the
slide b remains in its advanced position; Fig. 4 shows in dotted lines the position
of the delivering template after it has bent the iron around the stamp core. Now
the top stamp is moved ahead by the press slide N, and so the iron punched,
marked, bent at right angles, and cut off. During this operation the iron is
retained around the core of the stamp by the delivering apparatus. In the
meantime slide b has been moved back by the action of the excentric U, whereby
the jaws slipped back along the iron held fast on its end by the stamp. Now
through the mechanism acting upon cog ring m and led by the excentric way of
groove u, the delivering template is moved back into its original position, and the
press slide by action of excentric I is also drawn back, thus liberating the finished
heel iron in the stamp. Then in consequence of nose y acting upon disc Y the
pins a are pushed ahead, so the finished iron lifted off the bottom stamp and
thrown upon the inclined plane 10 leaving the machine through an opening 17 in
the finished state, shown in Fig. 6. Now slide b introduces the material necessary
for the next iron into the machine, and the play of the operations just described
begins anew.
This machine can be used for producing heel irons of all sizes. For this purpose
it is sufficient to adjust the stroke of the slide correspondingly, and to insert
into the machine the stamp and delivering template corresponding to the desired
size. This machine may also, by making some slight modifications, be used for
making horse shoes.
Having now described the nature and particulars of the said Invention,
I claim,―
1. The herein described mechanism for feeding the iron into the machine in

page_text: 2. The method of bending the iron by means of the herein described delivery
template and mechanism.
3. The method of cutting off the heel iron after the bending of the same has
been completed, thereby avoiding all trimmings.
4. The herein described peculiar construction of the stamp.
5. The positive back and forward motion of the press and transporting slide in
combination with the described stamp arrangement, all for the purpose and
substantially as described in reference to and as illustrated by the accompanying
Drawings.
In witness whereof, I, the said Walter Alfred Barlow, have hereunto set my
hand and seal, this Twelfth day of November, in the year of our Lord
One thousand eight hundred and eighty.
