This invention is applicable to the shaping or moulding of such objects from.
metallic or other materials which can be produced by a one sided pressure, the
stamping or moulding being produced by means of one or more rolls which is or
are moved past the piece to be moulded which piece is held in suitable tongs or
other holding appliances in such manner that the edge of the piece is by the
pressing operation moulded into the desired shape, the jaws of the tongs in some
cases being recessed for the metal or other material to flow into the recessed part of
the piece which thus acquires the desired formation there also. The roll or rolls
may be mounted between the forks on reciprocating slides or between oscillating or
revolving discs or levers and may act simultaneously or successively. They are
provided with suitable supports at the back for taking the pressure.
:
As applied to the formation of the toe part of a horse shoe or a great many
other objects which are to be formed with a turned up part or flange, a pressing
roll is mounted in bearings on a slide which by any suitable mechanism can be
moved up and down in guides on a frame. A table forming part of the framing is.
provided for the tongs which are to bold the piece to be moulded. The lower jaw
of the tongs is adjustably fixed to the table being for this purpose formed as a slide
which can be shifted in guides and adjusted by a screw ended wedge or otherwise
for getting in position the piece to be shaped relatively to the movement of the
pressing roll; when adjusted the slide jaw is fixed by a screw passing through an
oblong hole in the table. The front side of the slide jaw may be recessed as stated
for the metal of the piece to flow into. To this lower jaw is jointed the upper
lever shaped jaw having the jaw piece or jaw proper secured thereto by one or
more screw bolts, the distance between the two jaws can be yaried by interposed.

page_text: washers or pieces under the upper jaw piece. It is preferred to connect the upper
jaw by an eye bolt which by a pin through the eye is jointed to the lower jaw and
is provided with an angle or flange piece which with one leg of the angle passes
over the eyebolt and by the other leg can be adjusted so as to bring the upper jaw
piece more or less forward. This latter is accomplished by a wedge or set screw
between the said leg and a projection on the jaw. To bring the upper jaw down
on the piece to be held in place a knee lever is provided which with a friction roll
presses against the underside of the tail or lever end of the upper jaw, or the
objects to be shaped may be held in any other suitable holding appliance. They
may for instance be mounted in notches formed in the circumference of a disc,
and as the objects one by one are flanged by the pressing roll or rolls they are
when the disc is turned pushed out by coming in contact with adjustable arms or
stops.
In order to take the heavy pressure off the gudgeons or centres of the aforesaid
pressing and shaping roll the latter may be supported in various ways.
It may be supported by another roll at the back of it and fixed on an eccentric
axle having its bearings in the lower fork end of the slide, while the bearings of
the pressing or shaping roll are provided in a piece that is jointed to the slide and
can be adjusted relatively to the tongs by a set screw and by turning round the
aforesaid eccentric axle of the supporting roll. When using this means of adjust-
ment the above mentioned screw ended wedge for holding the piece to be shaped
may in many cases be dispensed with.
Or the pressing roll may have small bearings in a piece or plate that is fixed to
--the front of the slide while the supporting roll during the pressing operation
presses chiefly against a plate fixed behind the slide so that the supporting roll
is made to turn by the friction against the plate and the turning movement
transferred to the pressing roll by friction.
Or an upper and a lower supporting roll may be used in which case the gudgeons
or centres of the pressing roll may be omitted, a covering plate being provided to
keep the supporting rolls from dropping.
Or the supporting rolls may be entirely omitted in which case the pressing roll
is held against a backing or plate.
Or the pressing roll may be supported by two rolls the centres of the three rolls
forming the corners of a triangle.

I, PETER JENSEN of 33 Chancery Lane in the County of Middlesex do hereby
declare the nature of said Invention for "IMPROVEMENTS IN APPARATUS FOR
FORGING HORSE-SHOES AND OTHER ARTICLES HAVING PROJECTING FLANGES
(A Communication to me from abroad by "Kjöbenhavns Hesteskofabrik " of
Copenhagen Denmark Horseshoe Manufacturers) and in what manner the same is
to be performed to be particularly described and ascertained in and by the
following statement :-
This Invention is applicable to the shaping or moulding of such objects from
metallic or other materials which can be produced by a one sided pressure, the
stamping or moulding: being produced by means of one or more rolls which is or

page_text: are moved past the piece to be moulded which piece is held in suitable tongs or
other holding appliances in such manner that the edge of the piece is by the
pressing operation moulded into the desired shape, the jaws of the tongs in some
cases being recessed for the metal or other material to flow into the recessed part
and the piece thus acquires the desired formation there also. The roll or rolls may
be mounted between forks on reciprocating slides or between oscillating or revolving
discs or levers and may act simultaneously or successively. They are provided
with suitable supports at the back for taking the pressure.
As applied to the formation of the toe part of a horse shoe or a great many
other objects which are to be formed with a turned up part or flange; the apparatus
or machine may be constructed as shown in part section side elevation at Figure 1,
Figure 2 being plan of the tongs for holding the work to be operated upon.
The pressure roll a is mounted in bearings on a slide b which by any suitable
mechanism can be moved up and down in guides c on a frame h. A table g
forming part of the framing his provided for the tongs df which are to hold the
piece to be moulded. The lower jaw d of the tongs is adjustably fixed to the table
being for this purpose formed as a slide which can be shifted in guides g, and
adjusted by a screw ended wedge i or otherwise for getting in position the piece to
be shaped relatively to the movement of the pressing roll a; when adjusted the
slide jaw d is fixed by a screw l passing through an oblong hole in the table. The
front side of the slide jaw may be recessed as stated and as shown at x for the
metal of the piece to flow into. To this lower jaw d is jointed the upper lever
shaped jaw having the jaw piece for jaw proper secured thereto by one or more
screw bolts m; the distance between the two jaws d and f, p, can be varied by
interposed washers or pieces under the upper jaw piece f. It is preferred to connect
the upper jaw by an eye bolt m which by a pin n through the cye is jointed to the
lower jaw d and is provided with an angle or flange piece q which with one leg of
the angle passes over the eye bolt m and by the other leg can be adjusted so as to
bring the upper jaw piece f more or less forward. This latter is accomplished by
a wedge or set screw between the said leg and a projection on the jaw p. To
bring the upper jaw pf down on the piece to be held in place a knee levers is
provided which with a friction roll t presses against the underside of the tail or
lover end of the upper jaw p. Or the objects to be shaped may be held in any
other suitable holding appliance They may for instance be mounted in notches
formed in the circumference of a disc and as the objects one by one are flanged by
the pressing roll or rolls a they are when the disc is turned pushed out by coming
in contact with adjustable arms or stops.
In order to take the heavy pressure off the gudgeons or centres of the aforesaid
pressing and shaping roll, the latter may be supported in various ways.
It may thus be done as shown in the sectional side view Figure 3 and front view
Figure 4 where the pressing roll a is supported by another roll b, at the back of it
and fixed on an eccentric axle 63 having its bearings in the lower fork end of the
slide b while the bearings of the pressing or shaping roll a are provided in a
piece a that is jointed to the slide 6 by means of a pin a, and can be adjusted
relatively to the tongs by a set screw a, and by turning round the aforesaid
eccentric axle b, of the supporting roll b₂. When using this means of adjustment
the above mentioned screw ended wedge i Figure 2 for holding the piece to be
shaped may in many cases be dispensed with.
Or as shown in the sectional side view Figure 5 the pressing roll a may have
small bearings in a piece or plate a₂ that is fixed to the front of the slide b while
the supporting roll b, during the pressing operation presses chiefly against a plate
fixed behind the slide b so that the supporting roll be is made to turn by the friction
against the plate c₁ and the turning movement transferred to the pressing roll a by
friction.
Or as shown in the sectional side view Figure 6 an upper and a lower supporting
roll b₂ and b. respectively may be used in which case the gudgeons or centres of

page_text: the pressing roll a may be omitted, a covering plate a₂ being provided to keep the
supporting rolls b₂ b. from dropping out.
Or the supporting rolls may be entirely omitted in which case the pressing roll
is held against a backing or plate.
Or the pressing roll may as shown in the part sectional side view Figure 7 be
supported by two rolls b₂ b, the centres of the three rolls forming the corners of a
triangle. The objects as they are shaped will by the turning of the disc d be
pushed out of their notches q by the stop h.
Figure 8 is a side view showing four pressing rolls a mounted between two
revolving discs b (which take the place of the slide b and its guide c) and supported
behind by rolls by or plates as herein before described, The tongs for holding the
work to be operated on are brought forward or back relatively to the acting
pressing roll by means of a screw.
Having now particularly described and ascertained the nature of said Invention
and in what manner the same is to be performed I declare that what I claim as
the Invention communicated to me is:
First In machines for forming flanges on horseshoes and other articles the
application of a pressure roll a which is mounted in a reciprocating slide or
revolving or oscillating discs b and serves to forge or shape the article held in tongs
or clamp which is adjustable relatively to the roll a.
Second-Mounting the pressure roll a in a fork a, which turns on a pin a3, SO
that the roll may be adjusted relatively to the tongs, as described with reference to
Figures-3 and 4.
Third In combination with the roll a slide 6 and adjustable tongs the applica-
tion of rolls b, b, or fixed surfaces or both, for supporting the shaping roll a during
the work.
Fourth The application of suitable stationary frictional surfaces G₁, against
which the rolls b₂ b₁ roll during their motion with the pressing roll a
Fifth Mounting the rolls b₂ b. on eccentric spindles for the purpose of facilitating
the adjustment of the said rolls by turning the spindles.
Sixth-In machines for forming flanges on horse shoes and other articles the
application of a rotary disc d, having slots in the circumference for the receiving
the work to be operated on while the pressing roll a is mounted in an adjustable
and fixable support.
Seventh-In machines for forming flanges on horseshoes and other articles the
application of levers or stops h for automatically removing the shaped articles from
the disc a.
