Saxony.
I, WILLIAM LLOYD WISE, of Chandos Chambers, Adelphi, in the City
of Westminster, Patent Agent, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MANUFACTURING HORSE-SHOES, AND IN
APPARATUS FOR THE PURPOSE" (a communication to me from abroad by
Gustav Adolph Kästner, of Pieschen, near Dresden, in the Kingdom of
Saxony), to be as follows:-
:-
Many attempts have been made to accomplish the manufacture of
horse-shoes by machinery, most of the methods tried being based on the
principle of cutting the iron bar or horse-shoe bar into the necessary
lengths, heating the pieces so cut, and then during this heat completing
the horse-shoe by machinery by bending the iron piece, producing the
groove in the lower surface, and tapering the upper surface on one side
cither by pressure or otherwise. Most of these horse-shoe making
machines have failed to accomplish in a practicable manner the object

page_text: in view, partly on account of the machinery being too complicated for
such work, partly in consequence of several of the working parts of said
machinery being, as a matter of necessity, of such delicate forms or
dimensions that the cross section of the horse-shoe did not possess the
required accuracy, and further because the work turned out by said
machinery proved insufficient in regard to quantity.
Now according to this Invention horse-shoes are manufactured by
first producing bars of the requisite cross sectional form, then cutting
such bars into pieces cach of the proper length to make a horse-shoe,
and finally bending each piece into the form of a shoc. For these
purposes a rectangular bar of iron of proper size in cross section is
heated to a white heat, and while, so heated is caused to pass between
suitably formed rolls, thereby producing grooves at intervals in the side
of the bar intended to form the lower surfaces of the horse-shoes, and
tapering or bevilling a portion of the opposite side of the bar for its
entire length to form the tapered inner sides of the upper surfaces of
the shoes for establishing the outer borders upon which the hoofs rest.
The bar so prepared is then cut into lengths as already described, and
cach length is bent either by machinery or by hand into a properly
shaped horsc-shoe.
The apparatus employed for producing bars of the above-described
cross sectional form consists of a pair of rolls. The upper roll is made
of hard iron or steel, and has on its periphery suitable projections
arranged at proper distances apart to impress the grooves into the lower
surface of the bar, which surface faces the upper roll in passing through
the apparatus. The distances between the projections on the roll and
the lengths of said projections are such that two projections following
each other, in addition to one half of the distance before the first pro-
jection and one half of the distance beyond the second projection, will
correspond in their united dimensions with the length of the piece of
iron required for producing a shoe. The periphery of the lower roll is
formed to give to that side of the passing iron bar which faces it the
tapered or bevilled shape required to form the inner sides of the upper
surfaces of the shocs.
