HERBERT JOHN HADDAN, of Kensington, Middlesex, IMPROVEMENTS IN HORSE-
SHOE-BLANK ROLLS communicated to me from abroad by Samuel Thomas John
Coleman, John Norris Clarke and Edmund Bonaparte Reynolds, all of Cincinnati,
Hamilton County, State of Ohio, United States of America,
This invention comprises a special construction of rolls wherewith the peculiar
horseshoe blank-bar seen in fig 4, can be produced in the most uniform, rapid and
economical manner, said bar being capable of being subsequently cut into sections
and then bent, so as to afford two entirely distinct forms of horseshoes, as herein-
after more fully described.
In the annexed drawing:
Figs 1 and 2 are transverse sections showing approximate shapes of the bar that
is ordinarily used with the rolls. Fig 3 is an enlarged vertical section of said rolls,
a bar being shown in the act of traversing the "pass" of the same. Fig 4 is a
perspective view of the bar. Figs 5 and 6 are perspective views of two different
forms of blanks cut from said bar. Figs 7 and 8 are enlarged plans of shoes made
from said blanks. Fig 9 is a transverse section of a modified form of the bar.
Fig 10 is a section of a modification of the rolls.
The bar A which may be made either of iron, steel' or other suitable metal, is

page_text: first brought to substantially the shape seen in fig 1, and then to that seen in fig 2,
which shapes may be formed by running said bar through two passes of an
ordinary pair of rolls, or otherwise.
From these shaping rolls, the bar is taken to the finishing roll B, seen in fig 3,
reference to which illustration will show that said roll has two diametrically- 5
opposite dies C C³, extending some distance around the periphery thereof, which
dies produce the comparatively long marginal-projections F, of the bar, as seen in
fig 4, 5 and 6. Located at equal distances from the long die C, but on opposite
sides of the roll B, are two relatively-shorter dies D E, supplemented by a similar
pair D' E', which dies D D¹, E E', produce the smaller marginal-projections G G³, 1
of the bar A, it being understood that this finishing roll B, is arranged to form two
precisely similar blanks at each revolution. Said roll may, however, be of such
diameter as to turn out three or more blanks at every revolution.
Now, assuming that the bar is run through the roll in the direction indicated
by the arrow in fig 3, and that the die E, is the first to operate on said bar, it is
evident there is formed on the latter one of the shorter calks G.
Furthermore, it is apparent that the extended die C, will form on said bar one of
the long calks F, while the continued revolution of the roll will cause the other
dies D D¹, C'E', to act successively on the bar.
Hence, it follows that every complete revolution of roll B produces a bar having:
long projections F F, located at some distance from each other, and shorter
calks G G¹, G G₁, arranged in pairs comparatively close together, which disposition
of calks is repeated along the entire bar, the latter being rolled of any length
convenient for handling. Furthermore, the bar has rolled into it either at this
operation, or at a subsequent one, the creases H which extend from the base of
calks F to the base of calks G G. If the complete bar should now be cut so as to
include two of the long projections F F, and an intermediate pair of short
projections G G¹, as seen in fig 5, it is evident such a blank could be bent so as to
produce the shoe seen in fig 7, the long projections F F, forming the opposite
heel calks ff while the short projections G G', produce the toe calks g g¹,
respectively.
:
It is also apparent that the previously straight crease H, is now curved at h, and
is parallel with the outer margin of the shoe.
But by cutting of the bar so as to include one short projection at each end, and
an intermediate long projection, a blank will be formed similar to that represented
in fig 6.
This blank can then be re-heated and bent as seen in fig 8, the long projection F','
forming the single toe calk fl, while the shorter projections G₁ G, make the
opposite heel-calks g" g.
From this description it is evident that whichever form of shoe is made from
the bar, the toe and heel calks must be integral with the sole A, thereby avoiding
the labour and expense of welding on these pieces, and, at the same time, affording
a better and more durable article. The roll B, may be changed in its construction,
as seen in fig 10, where a somewhat shorter die O", is used instead of the die O¹.
Again the dies D", E", are not only shorter than the corresponding dies D¹E', seen
in fig 3, but are located comparatively near the die C", while the dies D, E, are
somewhat remote from the die C.
will
Consequently, that portion of the roll including the set of dies D¹¹, C"; E",
turn out a shorter blank than the dies D' C'E'. It, therefore, follows that every
complete revolution of the roll B, seen in fig 10, will produce one long blank, and
one shorter one.
As above described, the projections F G G³ of the bar are flat on their under or
bearing surfaces, but when it is desired to manufacture shoes having sharp calks,
said bar should be rolled with a ridge I, as seen in fig 9.
This blank will afford a shoe especially adapted for use when the streets are
covered with maw and inn

page_text: CLAIM:
The roll B for finishing horseshoe blanks or bars after they have been brought
to the proper form, said roll B, having a pair of long dies CC, between which, and
on opposite sides of the roll are situated two pairs of shorter dies D D', E E¹,
5 wherewith is produced the blank seen in fig 4.
In witness whereof I the said Herbert John Haddan have hereunto set my
hand and seal this 7th day of April A.D. 1883.
