COMPLETE SPECIFICATION.
An Improved Press or Apparatus for Simultaneously forming
Calkings and Clips upon the Toes of Shoes for Horses and other
Beasts of Burden.
I, OTTO KNIEP, of Schonebeck on the Elbe, in the German Empire, Manu-
facturing Blacksmith, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
In the making or manipulating of shoes for horses and other beasts of burden
for wear in frosty weather, it becomes necessary that such shoes have extensions or
projections called calkings, formed upon the toes as well as the heels, for the
purposes of forming bites for engaging with the ground in frosty weather, for
preventing the animal from slipping, and upon the sudden appearance of frosty
weather it frequently becomes necessary that shoes already upon the feet of the
animal, and partly worn, have to be removed to have the said calkings made or
put thereon, and hitherto this has been a lengthy and tedious process performed
by hand only, but my invention relates to a machine or apparatus or press by
means of which the said calkings and the usual clip, for embracing the toe of the
animal, may both be simultaneously formed and attached to the said shoe in about
half the time and at half the cost of such calkings when performed by hand.
According to my invention the shoe when made, or when removed from the
animals foot and heated, has formed in the toe thereof by the means of a punch
or other suitable tool, a preferably rectangular hole, into which is then placed
the heel or tenon of a heated metallic block, previously made by the before-
mentioned apparatus, when by reheating the toe of the said shoe and block
and placing both again in the machine, the said block is caused to form the
before mentioned toe clip and calking in one operation by the mere one rotation
of a shaft and toothed wheel.
In order that my invention and the manner of its operation may be fully.
understood I have hereunto appended two sheets of drawings, of which,
Fig. 1 Sheet 1 is a front elevation of my said machine or press, while Fig. 2
is a vertical section of same taken upon the line AB of Fig. 1.
Fig. 3 Sheet 2 is a section taken upon the line CD of Fig. 1.
Fig. 4 is a broken away portion of Fig. 1.
Fig. 5 is a section of Fig. 4 taken upon the line EF.
Fig. 6 is an enlarged detached view of a portion of Fig. 4.
Fig. 7 is a section of Fig. 6 taken upon the line GH, while Fig. 8 is a section
of Fig. 6 taken upon the line J K.
Fig. 9. is a section taken upon the line L M of Fig. 8.
Fig. 10 Sheet 1 is a plan and side view of an auxiliary tool used in the
manipulation of the machine, and hereinafter explained.

page_text: Fig. 11 Sheet 1 is an enlarged longitudinal section of a shoe about to be
operated upon by the machine. Fig. 12 is a like section of a shoe being operated
upon, while Fig. 13 is a like section of a shoe after being operated upon.
My invention consists of a suitably shaped frame A, carrying at its upper end
a transverse horizontal shaft B, and at its lower end a like shaft C, and an inter-
mediate like shaft D, the latter of which carries a spur wheel E, in gear with
a pinion E¹ upon the shaft C, the latter receiving motion by hand or any con-
venient available power for which purpose C may be provided with a suitable
handle, or a pulley a.
The shaft D carries eccentrically a pair of discs F, and between these a like
disc G, the frames 6 of the two I having extending jointed arms c, connected
by through bolts or pins with the joint of knee jointed levers H and H', the
upper members of which said levers are loosely mounted upon the shaft B,
while their lower members are each pivotally connected by bolts or pins to a
pair of lugs or ears dd', fixed upon or formed integrally with a cross bar J,
adapted to slide vertically upon guide rods e and el carried by the frame A.
The frame of the eccentric G has an extending jointed arm c¹, connected
in like manner with the joint of a knee jointed lever H2, the upper member of
which is also mounted upon the shaft B, while its lower member is pivotally
connected to the bifurcated upper end of a rod K, adapted to slide vertically
through a suitable hole made in the cross bar J.
From the foregoing and by reference to Figs. 1 and 2 it will be understood,
that the rotation of the shaft D would so operate the eccentrics and G that
these would impart a pull and push to their respective arms c and c¹ once to each
revolution of D, and that such pull and push on the part of the arms c of F
would raise and lower the cross bar J, while the arm c¹ of G would raise and
lower the rod K.
I have herein before mentioned that my invention operates by forming metallic
blocks having a heel or tenon adapted to engage with a rectangular hole formed
in the toe of the shoe upon which the said toe calking and hoof clip is to be
made, and the machine when not in use for making such calkings and clips upon
shoes may be employed for making the said blocks, which is performed in the
following manner.
The lower part of the frame A carries a table or block L, having upon its upper
face two or more (preferably four) pins or vertical studs f adapted to receive and
hold plates of varying, formation, according to their intended uses, which, for
the present purposes, may be of the shape shewn by M in Figs. 4 and 5: In the
under surface of the said plate are holes (not shewn) for the reception of the
studs so that M may rest upon the table L. In the under surface of the cross-
bar J is a vertical recess f¹ (shewn in dotted outline in Figs. 1 and 4) adapted to
receive the several punches or tools to be used by the machine, which for the
purposes at present under consideration consists of a block constructed substantially
as shewn by the enlarged detached views Figs. 6, 7, 8 and 9, and composed of a
preferably elliptical shaped plate g having a diagonally disposed slot g¹, in which
slides a block g³, adjustable within the said groove by the means of a threaded
rod g³, passing through the said block and carried in bearings g', provided by
the plate g.
The said plate g is formed upon its upper surface with a lug h
(Fig. 6) adapted to fit within the before mentioned recess f¹ in the cross bar J,
and having a hole ¹ coinciding with a like hole in J, that h may be retained in
fixed connection with J by the means of a bolt, screw, or pin j. The plate g
has upon its under surface a knife or chisel g, placed at the angle, or sub-
stantially so, shewn in Fig. 7, while the adjustable block g² carries upon its under
surface a finger-like-punch 96. The plate M has a lug j carrying a threaded
shaft, upon the end of which is a plate k¹ mounted at such an angle as to
correspond with that of the angle of the knife or chisel g³. The function of
the threaded shaft k is to regulate the distance between the guide plate and the
knife or chisel 95 for regulating the length of the block to be made, while the

page_text: threaded shaft g³ is for adjusting the position of the punch 96 for regulating the
position of the tenon or heel upon the said block, such adjustments being necessary
in the production of blocks of different sizes to suit large and small shoes.
The said blocks are cut from a length of heated iron rod of rectangular for-
mation in cross section, and a length of such a rod is shewn in position by 7 in
Figs. 4 and 5 resting upon the plate M the initial end of which said rod has been
previously cut to correspond in shape with the angle of the guide plate against
which the said end now rests, when, by imparting motion to the shaft I), the cross
bar J may be caused to lower, and the knife or chisel 95 to cut off a length from 1,
suitable for forming the said block 1, and at the same time the finger punch g
would press out so much of the side of the block being cut as to form thereon
a tenon or heel 12, the shape of the block when cut off being substantially that
shewn in Fig. 9, and such a block may be cut off at each downward movement of
the knife until the whole length of the bar is consumed, and the shoe to
which such a block is to be attached would, as before stated, be provided with
a rectangular hole at the toe through which the tenon or heel would be passed
from the upper side and burred over or clenched upon the under side, the shoe m
then appearing in cross section substantially as at Fig. 11.
The said burring over or clenching of the tenon 18 may be done by hand with
a suitable hammer when only one or a few shoes are to be done, but when many
are to be treated I employ the tongs Fig. 10. In such a case the block may be
placed in the groove n of the member n¹ of the said tongs and be therein gripped
by the closing of the member n³ suitable holes n³ being provided in the member n¹
for engaging with the studs f upon the table L, the shoe under such circumstances
being laid upon L, while a suitable flat faced punch connected to the lower end
of the member K of the knee lever H2, or such a block for this purpose may be
fixed in the recess f¹ of the cross-bar J the lowering of which said block may
effect the burring over or clenching of the tenon 12.
Assuming that a stock of the said blocks have been made and that one of
these has been connected to the toe of the shoe m as stated and as shewn in Fig. 11,
the formation of the toe calking and hoof clip is effected as follows.
The plate M must be removed from the table L and be replaced by a table N
(Figs. 3, 11 and 12) having holes p for engaging with the pins or studs f, and,
in its upper face a U shaped groover, of such size and configuration as to receive
the shoe m to be treated, (Fig. 3) the toe of which said shoe with its block /¹
has been previously heated. The groover is so formed that when the shoe m is
placed therein the toe portion of the said shoe slightly overhangs the edge of
the plate N as shewn in Fig. 11.
In the lower end of the rod K is fixed or formed integrally therewith a steel
block or punch P, having on either side a wheel or rollers to allow the said block
to pass freely the end of the plate N, the said plate end being curved at t as shewn
in Figs. 11 and 12. For the purposes of this part of my invention the recess fl
in the cross bar J receives a punch or die R, shaped substantially as at Figs. 11
and 12, and retained in f¹ by the tightening of the screw j.
The eccentrics F and G are so mounted upon the shaft D that the throw of the
ones F operating the movements of the cross-bar J are slightly in advance of the
one G operating the rod K, which provides, that if now the shaft D be rotated
the punch or die R would come down upon the block of the shoe m at the moment
that the punch P was in a position to form an abutment for the block as at
Fig. 11, so that the die R when forced down upon would press this into a shape
corresponding with that of the face of itself, and so form the calking w, and
immediately after this the punch P would be lowered and smear or spread the
overhanging end of the shoe m down the curved face t of the plate N, thus
forming the half clip x. This operation of P and R will be fully understood by
reference to Fig. 11 as preceding the operation, and Fig. 12 as after the operation
of forming w and x, while Fig. 13 will make clear the formation of the shoe m
when so finished.
