IMPROVEMENTS IN HORSE SHOE MACHINES (A Communication to me from
"
Steen Möller and Anders Andersen both of Copenhagen)
This invention relates to machines for grooving and punching blanks for horse
shoes, and it is used in connection with machines for cutting, rolling and shaping
the blanks before and after punching and grooving them
The horse shoe blank is held in place on a carriage between a raised side of the
same and a removable strip or clamp by means of a roller. The carriage rolls on
and is guided by a large guide wheel and two smaller rollers and passes the blank
under a sector-shaped die, which is keyed on and rotated by a spindle. The sector-
shaped die has a sharpened edge which forms the groove in the blank and upon
the edge of which are the punches which punch the nail holes. The roller is
journalled on the one end of a lever and by moving the free end of lever forward
or backward the roller is made to press the blank between or release it from the
clamp and the edge of the carriage. After the horse shoe blank has been cut off
to its desired length and has passed through a rolling machine to bring it down
to its proper dimensions, it is placed on the carriage between its side and the strip
or clamp. By now pulling over the lever the roller will press upon the strip and
clamp the blank in position. Next the die spindle is thrown into gear when the
sector shaped die will turn with its edge against the blank and cut the groove and
form the nail-holes by its sharp edge and the punches while the carriage rolls
forward on the rollers. After passing through the grooving and punching machine
the blank passes through appropriate machines for bending and shaping it to its
required form.

"IMPROVEMENTS IN HORSE-SHOE MACHINES (A communication to me by Steen
Möller and Anders Anderson, both of Copenhagen)
This Invention relates to machines for grooving and punching blanks for horse-
shoes, and it is used in connection with machines for cutting, rolling, and shaping
the blanks before and after punching and grooving them; and it consists in the
improved construction, combination, and arrangement of parts thereof, as herein-
after more fully described and claimed.
In the accompanying drawings; Figure 1 is a side view of the improved machine
for grooving and punching blanks for horseshoes, and Figure 2 is an end view
of the same.
Similar letters of reference indicate corresponding parts in both the Figures.
The horseshoe-blank is represented by the letter A in position for being grooved
and punched. It is held in place on a carriage B, between a raised side b of the
same and a removable strip or clamp D by means of a roller C. The carriage rolls
on and is guided by a large guide wheel E, and two smaller rollers F and F, and
passes the blank A under a sector-shaped die H, which is keyed on and rotated by
a spindle I. The sector-shaped die H has a sharpened edge h, which forms the
groove in the blank, and upon the edge of which are the punches h¹, which punch
the nail-holes. The roller C is journaled on the one end of lever G, which has its
fulcrum and is pivoted on an upright K, and by moving the free end of the lever G
forward or backward, the roller is made to press the blank between or release it
from the clamp or cleat D and the edge of the carriage B. After the horseshoe
blank has been cut off to its desired length and has passed through a rolling
machine to bring it down to its proper dimensions, it is placed on the carriage B,
between its side and the strip or clamp D. By now pulling over the lever G the
roller C will press upon the strip D and clamp the blank in position. Next the
die spindle I is thrown into gear by means of lever L, when the sector-shaped
die H will turn with its edge against the blank and cut the groove and form the
nail-holes by its sharp edge h and the punches h', while the carriage rolls forwards
on the rollers E and F F. After passing through the grooving and punching
machine the blank passes through appropriate machines for bending and shaping it
to its required form.
Having now described the nature of the said Invention and in what manner
the same is to be performed I declare that I claim as the Invention communicated
to me.
The combination, in a machine for grooving and punching nail-holes in blanks
for horse-shoes, of the carriage B, supporting and guiding rollers E and F F,
movable clamping bar D, lever G, having roller C at its inner end, sector shaped
die H, having the cutting edge h and punches h¹ and means for operating said
die, all constructed and combined to operate substantially in the manner and for
the purpose herein shown and set forth.
In witness whereof I the said Frederik Wolff have hereunto set my hand
and seal this sixth day of July in the year of our Lord One thousand eight
hundred and eighty three.
