An Improved Means and Apparatus for Forming Calkings or
Roughings upon Shoes for Horses and other Beasts of Burden.
I, OTTO KNIEP, of Schönebeck on the Elbe, in the German Empire, 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:-
My invention relates to a machine or apparatus for forming calkings or rough-
ings upon the heels of the shoes of horses and other beasts of burden, such calk-
ings being usually provided in frosty weather as a means of roughing the surface
of the shoe for preventing the animal from slipping, but some horse-owners prefer
to have such calkings upon the heels of their horse-shoes always, but whether
such calkings be placed or formed upon the shoe durings its manufacture, or
subsequently for the purposes of roughing, the objects of my invention are the
same, viz, to effect the formation of such calkings or roughings more quickly
than hitherto, and without disintegrating the molecules of the metal of which the
shoe is made, as obtains when suck calkings or roughings are provided by hand.
In order that my said invention and the manner of its operation inay be fully under-
stood, I have hereunto appended a sheet of drawings, of which,
Figs. 1 and 2 are diagrams referring to the manner of forming the said calkings or
roughings by hand as hitherto, while Figs. 3 and 4 are similar diagrams referring to
the forming of such calkings by the means of my machine or apparatus, as here-
inafter explained.
Figs. 5 and 6 are front elevations of my improved machine or apparatus, in two
different positions, while Figs 7 and 8 are sections of same taken upon the line A B
and C D respectively of Fig. 1.
My invention consists of a metallic frame composed of a base A, and vertical
sides A¹, the latter of which form bearings for a horizontal shaft B, carrying a
toothed wheel C, in gear with a pinion D upon a shaft E, borne by A¹ A¹, and
receiving motion from hand or other suitable power, and by which motion is conveyed.
to the shaft B.
The shaft B carries two eccentrically mounted dises F and G, in frames a and b res-
pectively, the former of which said frames has a depending rod F¹, having connected
to its lower end a punch F2, while the latter has a depending rod G, having attached
to its lower end a punch G2. An elliptical disc H is also mounted eccentrically upon
the shaft B, the periphery of which is always in contact with a roller J, adapted to
rotate within the forked end c of a rod K, arranged to slide vertically in a guide L,
carried by one of the uprights A', the said rod having connected to its lower end an
adjustable block M, and surrounded by a spiral spring d between c and L, the tension
of which said spring serves to raise the rod K, when permitted by the retirement
of the periphery of the disc H.
The vertical members A¹ of the frame of the machine carry a cross piece N, to which
is connected a vertical block O, having in its inner face a slot or horizontal groove e,
and a block P adapted to be brought closer to or farther from the said cross piece N
by the means of set screws f and f¹ respectively, the said blocks O and P serving

page_text: collectively to form a guide for the vertical movements of the punch F2, the upper
surface of which 9 is chamfered or bevelled at one side g¹ for purposes hereinafter
explained.
The discs F, G and H are so mounted eccentrically upon the shaft B, that whilst
the rod F¹ and its punch F2 is rising, the rod G¹ and its punch G2 is lowering, and
during these movements of both F2 and G2 the rod K with its block M is kept
in its lowest position.
In forming calkings or roughings upon the shoes of horses and other beasts of
burden by hand as at present, it is usual to first turn up the calking or heel h of the
shoek substantially as at Fig. 1, the portion h being subsequently bent as at Fig. 2,
and eventually brought into an upright position, but during this operation the mole-
cules of the metal become ruptured or disintegrated, so that a flaw not infrequently
occurs in the said calking or calkings unseen, and not known of, until such calking
breaks off, and if not then noticed by the driver the fetlock joint of the animal may
become sprained and the animal lamed, but my invention is designed to obviate this,
and my machine or apparatus operates as follows.
The shoe k upon which the calkings are to be made would be first rendered red
hot in the forge in the usual way, when the sinith would place the under surface of
one of the sides or members of the shoe flatwise upon the block P, with the end h
of the said member within the groove or slot e in the block O, at which moment the
block M and the punches F2 and P would presumably be in the position shewn in
Fig. 5, motion would then be imparted to the shaft B and the eccentric discs
thereon, and the first movement of the one H, would commence to lower the rod K,
until the point m of the major axis of H was in contact with the roller J, at which
moment the block M would be in its lowest position, pressing down the member of
the shoe upon the block P, as shewn in Fig. 6, when the smith may release his
hold upon the shoe k leaving the apparatus to do the rest. The continued rotation
of the shaft B would cause the eccentric disc F, to raise the rod F¹ and the
punch F2, and the upper edge g of the latter, coming in contact with the member
of the shoe k, would force this in an upward direction, causing it to assume the
shape indicated by Fig. 4, by reason of its end h being within the groove or slot e in
the fixed block O, but the continued upward travel of F2 would ultimately so bend
the member k, in the direction named, as to draw its end h out of the slot or
groove e, and the continued movement of F2 would, after such withdrawal of h from e,
cause first the sloping surface g¹ and then the side g² of F2 to engage with the said
end h, the first producing the shape shown in Fig. 1, and the second that shewn in
Fig. 3 or thereabouts, and at the moment that the block F2 had performed all its
functions upon the said upturned end h of k, the eccentric G would have caused the
block G2 to have lowered upon the said upturned end h as shewn in Fig. 6, and the
downward pressure from this, and the fact that the said upturned portion h is still
held between F2 and P, would give to this the rectangular formation shewn in
Figs. 3 and 6.
During the movements of the eccentrics F and G, and the performance of their
punches F2 and G described, the periphery of the disc H from m to m', and
from m¹ to m² would have passed over the reel J, and at the moment that the
punch G2 had finished its work upon h, the portion m² of H would have passed the
roller J, when the latter, its rod K, and block. M, would be raised to their first or
initial positions (as shewn in Fig. 5) by the tension of the spring d, and by the time
the disc H had reached this position (shewn by Fig. 7) the eccentric discs F and G
would have lowered and raised their punches F2 and G2 respectively, into their first
or initial positions shewn in Fig. 5, the whole of which said operations upon the
member k being performed by one rotation of the shaft B. The member of the
shoek operated upon may now be removed and the other member treated in like
manner.
The block P being adjustable upon the crossbar N provides for the reception
and manipulation of shoes, the members of which may differ in size, the block M
being rendered interchangeable for similar reasons.

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

of horses and other beasts of burden, substantially as herein described and shewn.
2nd. In a machine or apparatus for forming calkings or roughings upon the shoes
