page_text: 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 THE MANUFACTURE OF
HORSE-SHOES to be as follows:-
"
This invention has for its object the construction of a machine adapted to form
horse-shoes from a plain bar of heated iron, at one operation, converting it into
completed horse-shoes; and it consists of the following members constructed
combined and connected together so as to operate in unison, viz:
First, a pair of rollers through or between which the heated bar of iron is passed,
having grooves in their peripheries so formed as to impart to the bar shapes
corresponding to the style of horse-shoes it is desired to make, thus converting the
bar into a series of blanks connected together end to end. The bearing frames of
these rollers are adjustable to permit of different size rollers being used in one
machine, and also to locate them in proper position in relation to the other
members of the machine; they are by means of suitable gearing caused to rotate
intermittently. These rollers in addition to the function performed by them of
shaping the bar of iron into shoe blanks, also act as feed rollers to the other
members of the machine to present the blanks thereto.
Secondly, a cutting off device composed of a vertically moving punch so shaped
as to properly form the contiguous ends of two blanks of the bar, when it separates
the end blank from the bar, is caused to act when the forming and feeding rollers
are stationary, leaving the severed blank in proper position to be acted upon by
the folding or bending device, which constitutes the third main member of the
machine. This cutting off device is adjustable to and from the forming and
feeding rollers, thereby enabling it to be set to properly sever blanks of different
lengths.
Thirdly, a folding or bending device comprising two rollers on vertical studs in
front of which the end blank on the bar is fed, and there left by the cutting-off
device; a horizontally moving plunger having a shape corresponding to the inside
of the horse-shoe, and which forces the blank between the rollers on the vertical

page_text: studs after it has been cut off by the cutting-off device; a pair of pivotted folders
into and between which the plunger forces the blank after it has been partly bent
around the plunger by being forced between the rollers; the pivotted folders
thereby completing the shoe by giving it the desired external form; a trap door
provided in the bed or table immediately below the pivotted folders, and a stripper
for knocking the shoe off the plunger and through the trap door, when the plunger
has moved back a short distance and the pivotted folders opened sufficiently to
permit the formed shoe being pushed clear of thein.
The main members with their several working parts or devices above indicated,
are connected together and actuated by suitable gearing, cams, &c, so as to operate
in unison and form a completed horse-shoe at cach full revolution of the main
shaft of the machine.

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 the 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 for its object the construction of a machine adapted to form
horseshoes from a plain har of heated iron at one operation converting the whole
into shoes; and it consists of a pair of feeding and blank forming rollers arranged
to feed the blank bar horizontally and form it into blanks, a vertically arranged
cutter for separating the blanks and forming their ends, during which operation,
the feeding rollers are at rest a plunger and folders for forming the blanks into
shoes as they are cut off from the bar by the cutter arranged to operate hori-
zontally at right angles to the direction of motion of the blank bar.fed by the
feeding and forming rollers, and a vertically operating stripper for forcing the
formed shoe off from the plunger.
The various parts of the machine are adjustable, and the bearing supports of the
feeding and forming rollers are so made as to adapt them to receive different sizes
and forms of rollers, so that all kinds and sizes of horseshoes can be made on the
one machine.
But to describe my invention more particularly I will now refer to the
accompanying drawings, in which:-
Fig. 1, sheet 1, is a general plan view of the machine;
Fig. 2, sheet 2, is a side elevation ;
Fig. 3, sheet 2, is a front elevation; .
Fig. 4, sheet 2, is a part rear elevation;
Fig. 5, sheet 1, is a central sectional elevation of the folding mechanism taken
on the line x, x, fig. 1;
Fig. 6, sheet 1, is a plan view of the same on an enlarged scale, showing the
folders open;
Fig. 7, sheet 1, is a similar view showing the folders closed;
Fig. 8, sheet 2, is a sectional elevation of the feeding and forming rollers, the
cutter and the folding device, taken on the line y, y, fig. 1; and
Fig. 9, sheet 2, is an enlarged transverse section of the folding device taken on
the line z, z, fig. 7.
All the parts of the machine are supported on the bed plate a, by means of
suitable standards and frames bolted thereto.
The driving shaft b, provided with the heavy fly wheel 6¹, rotates in bearings in
the standards a¹, a', and has secured to it the pinion b², meshing into the wheel c,
on the shaft c', supported in the standards a², u², which shaft actuates the feeding
and forming rollers and cutting-off punch. On the end of the shaft b, is secured
the bevel pinion b³, which meshes into the bevel wheel d, secured to the shaft d¹.
This shaft d', rotates in bearings in the standards a³, a³, and has also secured to it
the segmental or mutilated gear wheel d³, having teeth d³, on one half of its
periphery only, the other half of the wheel being a plain concentric surface d', of

page_text: t
.
smaller diameter than the toothed part. The teeth of this wheel mesh into the
pinion e, which has a large tooth or double horn shaped projection e¹, the outer
surface of which is concaved so as to fit on the plain concentric surface d*, of the
wheel d²; the pinion e, when in this position is held stationary during a half
revolution of the wheel d², but makes a full revolution when the teeth d³, pass
around so as to mesh into its teeth, the changes from rest to motion and vice versa
being insured by the horns on the projections e¹, passing into the undercut recesses
ds, ds, at the juncture of the toothed part d³, with the plain surface d².
The shaft of this pinion e, rotates in the bearing standards a, a, and has
secured to its end the cams &c which actuate the folding mechanism of the
machine.
The gearing above described constitutes the driving mechanism for the various
members of the machine, which I will now describe in the order of their operation.
The forming and feeding rollers f and f¹, have grooves formed in their
peripheries corresponding to the shape of the blanks into which it is desired to
convert the bar of iron, which bar is presented to these rollers in a heated con-
dition. Half boxes f³, f, fitted to slide in vertical guides on the standards a³, a³,
form the bearings for the rollers fand f¹, the top boxes f³, f³, being held down by
large screws fo, fo, passing through the tops of the standards, and the lower boxes
ff, being held up by the screws fo, fo, secured to them, and which fit into
tapped holes formed in the miter wheels f', f", said miter wheels having bearings
in bridge pieces formed across the lower ends of the guides in the standards a³, a³.
Gear wheels f8, 78, secured to the ends of the shafts of rollers f, f¹, connect these
rollers together.
In line with the axis of the lower roller f¹, is placed the shaft g, having an open
coupling g', on its end, into which fits the end of the shaft of roller f¹. This
shaft g, rotates in bearing boxes g*, gå, fitted to slide in guides in the standards
a, a; and these boxes g², g2, have secured in them the screws g³, g³, resting in
tapped holes in the miter wheels g, g*, which are fitted to rotate only in bridge
pieces formed in the standards a, . All of these miter wheel nuts f¹, ƒ³, gª, 9ª,
mesh into corresponding miter wheels 95, 98, secured to the shaft 96, having
bearings in the standards a, a, and provided on its end with a square, by means
of which, with a suitable wrench or handle it can be rotated, thereby raising or
lowering the roller f', and shaft g, simultaneously, and setting the upper surface
of the roller f¹, at the proper level to enable the blank as formed on the bar to be
fed to the other parts of the machine. This construction admits of the easy
vertical adjustment of different size rollers, which will vary with each size of shoe
made; and as such also requires nice adjustment as to position in relation to the
folding mechanism, which is fixed, all of the standards a, a, are fitted to slide on
the bed a, but securely held thereto by means of bolts passing through slotted
holes in their bases; and they are caused to move together by the screws h,
working in the ends of their bases, and having bearings in a flange projecting up
from the bed a, each screw being provided on its end with a bevel wheel ', in
.which meshes one of the bevel pinious h², secured to the shafts, also having
bearings in the bed a, and provided with a square end by which it may be rotated.
Intermittent rotary motion is imparted to the rollers f, and f', from a crank
pin i, projecting from a disc secured to the end of the shaft c', which crank pin is
connected by means of the rod i¹, to the end of the arm 2, rocking on the shaft g,
said arm being provided with a dog or pawl which catches into notches formed in
the periphery of the disc ³, rigidly secured to the shaft g. The connecting rod ¹,
is provided with a turnbuckle or other suitable device by which its length may
be adjusted to accommodate for the different positions in which the shaft g,
may be set.
The number of notches in the disk i, corresponds to the number of blanks the
rollers and f¹ will form while making a full revolution, which in this case is
shown to be three. And when the rollers are in a position of rest, as shown, the
end of the formed blank is located contrally between the two rollers f, and f¹. In

page_text: figure 4, the shaft c rotates as indicated by the arrow and the rollers are about to
move to form a blank and feed the preceding blank into the folding mechanism.
The cutting-off punch j, cuts a small piece out of the bar between two adjoining
blanks and is so shaped as to form the ends of these two blanks, k and k¹, as
shown at fig. 6; it is carried by the plunger j¹, fitted to slide in the frame 1,
projecting up from the frame a', which carries the folding mechanism; and in this
frame 2, is fitted the shaft l, provided with the tappet, arranged to operate the
plunger j, by projecting into an opening formed therein. On the end of the
shaft l, is secured an arm 12, having a roller on its end, against which works the
cam 13, secured to the shaft c¹. This end of the arm 12, is pulled down against
the action of the cam 1, and the plunger j¹ and punch ; raised, by means of the
spring 1.
In ways formed in the horizontal bed of the folding mechanism is secured the
die m, by means of the set screws m¹, ml; this die m, is adjustable in its ways to
and from the folding mechanism, as is also the punch j, adjustable on the plunger j¹,
so as to be properly set to cut off different lengths of blanks.
When the blank k, is fed on to the horizontal table n, it is immediately in front
of the folding rollers n¹, n', rotating on studs fixed in the table n, and the end of
the blank is in contact with the adjustable stop n². The plunger o, which is
shaped to conform to the inside of the finished shoe, is carried by the slide o¹,
fitted in guides in the frames a, a, and connected at its rear end to the crank
pin o², projecting from a disc secured to the shaft of pinion e, by means of the
connecting rod o³, which is made adjustable as to length to enable the plunger o to
be set in relation to the other parts of the folding or bending mechanism.
The plunger o, in coming forward, forces the blank k, between the rollers n¹, n¹,
thereby folding the blank on the plunger, which then carries it forward into the
folding dies p, p, pivoted on the table n, at p¹, p¹, and held open by the springs
p², p, against the adjustable stop screws p³, p³. When the blank ou the plunger o,
comes in contact with the bottoms of the folding dies p, p, said dies are forced
back, causing their sides to press the blank firmly around the plunger o, as shown
at fig. 7.
In the horizontal table n, is placed a trap door q, pivoted at q', and held up by
the roiler on the end of the lever r, which is pivoted at r, to a projection from
the frame a', the other end of the lever having a roller which bears on the cam r²,
secured to the shaft of the pinion e. The spring pulls down the inner end of
the lever r, to allow the trap door q, to fall, just as the plunger o, commences its
retrograde movement. Fig. 5 shows this trap door q partly open.
The shoe k, is knocked off the plunger o, as soon as the plunger has moved back
clear of the folding dies p, p, through the opening in the table, by means of the
stripper 8, which has three pius or lugs so as to strike the shoe on the sides and
front end; and it is carried on one end of the lever s¹, pivoted at s², to the frame a²,
the other end of said lever being provided with a roller and actuated by the can t,
secured to the shaft of the pinion e. The stripper 8, is raised up by the spring u,
when it has knocked the shoe off the plunger o.
The shoe on leaving the plunger, falls on the trap door q, and from thence on to
the shute v, which guides it clear of the machine.
A guide w, is provided to insure the blanks, as they are formed on the bar,
coming in proper position under the punch j.
The operation of the machine is as follows, the cams and operating mechanism of
the various members being adjusted and set as shown to cause all the parts to
work in unison. The end of the heated bar of iron is presented to the rollers f
and when they are at rest; one notion of the roller operating mechanism forms
a blank k, and feeds the bar forward so that its end is directly under the punch j,
which now operates while the rollers f and f' are at rest, aud forms the free end
of the blank k.
Upon a repetition of the movement of the rollers f and f', the next blank k' is
formed, the blank being fed into the folding or bending device, the adjoining ends

page_text: of the two blanks k and k¹ resting directly under the punch j. The punch ; now
works, separates the blank k from the bar, and forms the adjacent ends of the two
blanks, as shown at fig. 6. During this operation the plunger o commences to
move forward, and by the time the blank k has been severed from the bar, the
plunger is in position to force the blank between the folding rollers n¹, n¹, so that
said blank, when thus severed, is retained between the end of the plunger o and
rollers n¹, n¹, the stop n² forming an end guide for the same. The plunger o now
forces the blank through the rollers n¹, n¹, and into the pivoted folding dies p, p,
which are caused to firmly press the blank on to the plunger by the pressure
applied to them by the end of the plunger o, and the shoe carried thereby,
completing the bending operation, as shown at fig. 7.
Upon a retrograde movement of the plunger o, the folding dies p, p, are opened
out clear of the shoe on the plunger by their springs p², p², the trap door q, in the
horizontal table n, is lowered, and the stripper s operated to knock the shoe off
the plunger, through the opening in the table, the shute v guiding it clear of the
machine, as shown at w¹, fig. 3.
The plunger moves back into the position shown in the principal views of the
drawings and remains stationary while the rollers f and fi are forming another
blank on the bar and feeding the end blank forward into the folding or bending
device; then the bending operation is again repeated, and so on.
The shoes, as they leave the machine are still hot, as so little time is occupied in
their formation, the machine forming and bending a shoe at each full revolution of
the same, so if it is desired to submit any particular kind of a shoe to a further
operation which could not be conveniently done in this machine, or to form nail
holes therein, the shoes may be taken from the machine as soon as formed and
submitted to said further operation.
