"
The nature of our invention is defined in the claims hereinafter presented.
In the drawings, A denotes the frame of the machine supported in bearings a a
in which is a shaft B, having fixed on one end of it a gear C, engaging with a
pinion D, secured on a driving-shaft E, sustained in bearings bb, fixed to the frame
of the machine, the said shaft E being provided with a fast pulley F and a loose
pulley G.
Keyed to the shaft B and arranged centrally thereon, between the sides of the
frame A, is a bed-plate F, the periphery of which, except where it is provided with
The
the curved bearings e c, (see Figs. 2 and 19,) is concentric with the shaft B.
said bearings c e, of which there may be two or more in number, are arranged at
regular intervals, the curved surface of each being the arc of a circle, and each
receives and supports a semi-circular rocker G, having flanges e e to keep it in

page_text: position in the bed-plate. Said rocker also has a notch f to receive a projection g
from a supporter H, to which is secured the shoe-forming die I, as shown. Projecting
from the supporter H are flanges h h, which rest against the sides of the rocker G
and keep it in its due relation therewith. Pins i i, secured in opposite sides of the
supporter H, serve as pivots for the outer ends of headed rods j, arranged within and
projecting from spring-cases k, secured to opposite, sides of the hed-plate F¹. The
springs in said cases encircle the rods j, and are compressed hetween the head of the
said rods and the head of the cases k, and serve to keep the faces of the supporter H
against the periphery of the circular auxiliary bed-plates U U, hereinafter referred
to, and the circular face of the rockers G against their bearings in the bed-plate.
(See Figs. 2, 3, and 19.)
Supported in bearings m m in the front portion of the frame A is an eccentric-
shaft J, having fixed to one end of it a gear K, engaging with the pinion D. Said
gear, owing to the fact that the bed-plate is shown as having but two shoe-forming
dies, is provided with half the number of teeth of the gear C. Encompassing the
eccontric portion of the shaft J is a sleeve forming part of a pitman M, its upper
end being pivoted at n to a slide N, carrying the swaging devices o o¹, which
operate with the abutments p p' to thicken the ends of the bar of iron to form the
shoe, and the pieces o and p also serve as shears to sever the said bar after being fed
the proper distance into the machine, or until it reaches a gage p¹, provided with
means for adjusting it and clamping it in position.
2.
A plate q is secured to the front of the machine and supports gibs, between it
and the slide N, and has scrows for adjusting the gibs against the slide to compensate
for the wear of said slide and its ways. Extending from said plate 9 and resting
against one side of the frame of the machine is a bracket O, pivoted to which and
so as to revolve in a horizontal plane is a series of rolls s, (see Figs. 1, 4, 17 and 18.)
one of said rolls being connected to a gear t, engaging with a gear u, fixed to an
arbor provided with a roll v and a crank-wheel w, supported by a slide, which can
ho adjusted horizontally with relation to the rolls s by a screw y, so as to cause the
roll to bear against a bar of iron when between it and the rolls s sufficiently to feed
the said bar through the passage and into the machine by turning the hand-
wheel w. (See Figs. 17 and 18.) The slide a is sustained in another slide z, which
can be adjusted horizontally by a screw in a direction at right angles to that in
which the slide can be moved, said slide æ having a guide b¹, arranged in front of
the rolls 8, as shown, to keep the bar in position against said rolls, and the said slide
is clamped in position in the bracket O by a screw c¹, arranged in a groove d'
therein.
Extending upward from the front portion of the frame is a yoke L, to which is
pivoted at e the levers P P, which carry the bonding-rolls f'f'. (See Figs. 2, 17, 21
and 22.) These rolls are supported so that they can freely turn on bolts, fixed
to the arms by nuts g³, and are slightly tapering, the ends of said rolls having the
larger diameter being next the levers P, and the upper ends of the said levers are
drawn toward each other by a spring g'. The object in tapering the rolls f¹ƒ³ is to
insure the forcing of the surface of the shoe, which, when it is completed, is the top
surface of it, so that said surface shall bear near its outer edge on the face of the
forming-die L. (See Figs. 23 and 24.) This will cause the bar to stand with relation
to the die essentially as shown in dotted lines in Fig. 23. This is done to prevent
the creases in the shoe from being narrowed or partially closed while the shoe is
being acted on by the hammer, it being so arranged that when the die is passing
under the hammer, the hammer shall barely touch the outer edges of the creases in
forcing the shoe against the face of the die to incline or concave its upper
surface.
Above the bed-plate F¹, and mounted in bearings in the frame A, is a shaft Q,
the part of it between the said bearings being eccentric to the journals of said shaft,
and on said eccentric is arranged a hammer R, applied to it so that it can revolve
thereon. The said shaft is provided with a driving-pulley S.
Pivoted to a rod h³, supported in bearings * in the upper part of the frame A, are

page_text: two gravitating arms T, which rest at their free ends (see Fig. 2) on the periphery of
auxiliary bed-plates U, supported on the hub of the bed F', so that they can turn
thereon. The peripheries of said auxiliary bed-plates furnish bearings for the faces s
of the supporters H, and, together with the bed-plate F sustain the die when the
blank is forced against it during the bending of it, and also while being acted upon
by the hammer R. Each of the arms T has an inwardly-projecting ledge, on which
rests a slide V, projections k¹ from said slide extending into slots in the arms T.
Supported on said projections k¹, and pivoted to pins m', projecting upward from the
slide V, are nippers W, the tails n' of which rest on the projections ¹ and extend
into the said slots in the arms T. Each nipper has a roll of pivoted to it, which enters
curved notches p² or p³ in the arms T when the slide V is at either extreme of its
range of movement in said arms. When the slide V is in its lowest or forward
position in said arms T, as shown in Fig. 2, the rolls o³ are moved into the notches/
by the tails n' of the nippers striking against the lower or forward ends of the slots
in said arms T. (See Fig. 13.) The slide V and its nippers when in this latter
position are ready to receive the shoe-forming die I with a shoe upon it, and supposing
the bed-plate F to be in revolution in the direction indicated by the arrow in Fig. 2.
when the advance end of the supporter H strikes the inclined portion s' of the arms T,
said arms will swing upward on their pivot into a horizontal position and bring up
against stops 2. fixed in a yoke A2, secured to the frame of the machine, and the
die I, with the shoe, will pass between the nippers W and on the advanced or toe-
portion of the said die striking the slide V at 1, the said slide will be carried forwar
with the die, and as the rolls are moved out of the notches p³ of the arms T the
nippers W will turn on the pivots m' and their jaws t' will grasp the shoe near it
ends and firmly hold said shoe to the die while the rolls move along against the straight
portion of the arms T.
The arms T so operate the die supporter H and the rocker G as to maintain the
die I with the shoe thereupon and held thereto as hereinbefore set forth, in a horizontal
position while passing under and being operated upon by the hammor, so that the
shoe when it leaves the hammer will be straight when viewed in edgo viow and not
curved as are the shoes heretofore made in machines having the forming dies
supported on a bed rotative on a horizontal axis.
The shoe having passed from under the hammer is released from the grip of the
nippers by the rolls o swinging into the notches p³ of the arms T and at the same
time the toe of the shoe will slip passed and be carried under the part of the slide V
and in its downward course will meet the clearers which are adjusted to pass
between the shoo and the die and disengage it therefrom and cause it to pass down the
chute X.
The chute X is supported on a shaft Y sustained in bearings fixed to the frame A
and has clamped to it an arm u provided with a set screw which passes through
said arm and bears on the frame. A spring secured to the free end of said arm
and to the frame keeps the set screw u² against the frame and allows the chute to
swing in its bearings when the die is moving in contact with the clearers. The said
clearers are secured in position by clamp screws and nuts as shown which admit of
their adjustment.
The bar B from which the shoes are to be is represented as creased and rolled
into the required shape and when introduced into the machine is to be heated to the
proper temperature to enable the forming of it to be carried on.
The operation of the machine may be thus described. The bar having been creased.
partially punched and rolled into the required shape as shown in Figs. 25, 26 and 27
is introduced in a heated state between the guide b¹ and rolls s (see Fig. 4) till it is
gripped by the roll v, when the attendant by revolving the crank wheel to advances
the bar through the passage ¹ a proper distance or till its forward end reaches the
gage p (see Fig. 17) the bar being represented in dotted lines. The machine being
in operation the slide N will now rise and advance the swaging dies o o' the portion of
the bar within the machine and between the gage p* and the cutting edge of of the
die o being severed from the bar by the edge of and the lower end p of the abutment p

page_text: which serve as shears. The severed portion of the bar or the shoeblank will next be
compressed between the swaging dies p p' and o o¹ to thicken its ends immediately
following which the forming die I will rise against the middle of the said blank and
the swaging dies oo' will simultaneously retreat from it. The said forming die I in
advancing will force the blank between and against the rolls fl and successively,
the former bending the toe portion of the blank and the latter the quarters and heel
portions. The spring g¹ resisting the spread of the upper arms of the levers PP
causes the rolls f to bear the inner edge of the blank firmly against the edge of the
die, and the taper of the said rolls f¹ and causes them to force the surface of the
blank near its outer edge which is the top surface of the shoe against the face ³ of
the die (see Figs. 23 and 24). It will be observed that when the die I bears the
blank against the rolls the rocker G will turn in its bearing in the bed plate so as
to bring the face of the said die into parallelism with the inner face of the levers B
which position it will hold till the ends of the shoe blank pass from contact with the
rolls when the rocker will assume its normal position. The dic continuing to
advance, when the forward end of the supporter H reaches and moves against the
incliness of the arms T, said arms will be raised against the stops and into a
horizontal position and the toe of the die I, meeting the part y of the slide V, will
carry said slide forward and cause the nippers W to grasp the shoe as hereinbefore
described and hold it firmly to the dic. The rocker G when the supporter passes
under the said arms, will turn in its bearing, so as to cause the surfaces of the
said supportor to bear fairly against the surface s of the arms T (see Fig. 19) and
this movement of the rocker in its bearing will maintain the dio I and its supporter
in a horizontal position while said surfaces are in contact, and the shoe is being
subjected to the action of the hammer R, after which the nippers will be caused to
release their hold on the shoe as hereinbefore set forth and the surfaco s³ of the
supporter being carried out of contact with the surfaces of the arms T the rocker
will again assume its normal position depress the toe of the die and carry it under
the part 9 of the slide V. The free ends of the arms T as soon as said surfaces s
and pass out of contact will drop onto the periphery of the auxiliary beds U,
the slide V will move forward into the position shown in Fig. 2. and the die I
with the shoe will pass onto the clearers 12 which will entor between the shoo and
die and release the said shoe from the die so that it will pass into the chute ✗
and be conducted from the machine.
From the foregoing it will be seen that by our improvements a horse shoe, when
it passes from the machine herein before described is much nearer completion than
are the shoes formed in the machines heretofore in use, provided with dies fixed
in the periphery of a rotary supporting-bed as the shoes formed in said machines
are curved as seen in edge view, and before they can be used must be subjected
to a straightening process in another machine adapted for the purpose, whereas the
shoes formed in our machine are straight in this particular when they leave the
machine, and do not require any such treatment.
Furthermore this machine admits of the making of a rolled or a hammered shoe,
and when it is desired to make the latter the shaft is revolved in its bearings by a
belt applied to the pulley S, which will impart to the hammer the proper motion but
when it is desired to make a rolled shoe the belt is removed from the pulley S and the
shaft Q is turned in its bearings till the sleeve R is brought into the desired or propor
position with relation to the die. Then said shaft is clamped in its bearings so that it
cannot revolve, in which case the sleeve will turn on the said shaft and roll the shue
against its die as it passes along underneath and in contact with the said sleeve.

tion and in what manner the same is to be performed we declare that what we
