Improvements in Die Rolls for Making Horse Shoe Blank Bars.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents.
45, Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention, and in what manner the same is to be performed, to
he particularly described and ascertained in and by the following statement :-
This invention relates to die rolls for making horse shoe blank bars.
In an application for Letters Patent of even date herewith, I have described a
certain method or process of manufacturing blanks and blank bars, and among other
forms of mechanism therein disclosed are the die rolls which form the subject of
my present application.
The said blanks and blank bars have been devised by me with special reference
to their use in the manufacture of what are known as "toe weighted" shoes, and
die rolls embodying my present invention are employed for producing blanks and
blank bars, suited to the manufacture of two varieties of horse shoes of that class.
My improved die rolls, convert a plain straight edged bar of metal, into blank
bars which are readily divisible on diagonal lines, in such a manner that each blank
will have a wide toe portion, and two narrow ends or heel portions, and these
blanks lie in two parallel series in the bar.
The principal feature of novelty in a die roll embodying my present invention,
consists in providing the working face of the roll with two series of creasers so
disposed in pairs in each series that each pair will operate in forming the nail
creases or scores in each blank, but these pairs in either series, alternate in position
with the pairs of ercasers in the other series, as distinguished from having each
creaser in one series, exactly opposite another creaser in the other series as in all
prior die rolls for producing double horse shoe blank bars. By this novel
arrangement of the creaser, the blanks are properly scored although they so lie in
the bar, that the toe portion of any one blank lies laterally opposite two heel
portions of two other blanks, as distinguished from prior horse shoe blank bars of
the double form, in all of which, each two blanks lie side by side.
A second and equally important feature of novelty in my present rolls, consists
of a peculiar grooving tongue for forming a zig-zag groove between the lines or
series of blanks. This grooving tongue has an edge which is truly circular in its
peripheral outline, but its edge inclines in straight lines to and fro, each straight.
line being equal to one half of the length of any particular blank required for
forming a given size of shoe.
This tongue may be uniform in its cross section, as is desirable in making certain
varieties of blanks, but for producing a preferred form of blank used in making
fancy shoes, the tongue is varied in its form, so as to produce a wide flat
bevel at the toe portion of a blank, and narrow steep bevels at its two ends or heel
portions.
;
A further novel feature in my die roll consists in providing it with spurs for
marking the parting lines between the abutting heel portions of each two blanks
said spurs at one edge of the roll, alternating in position with the spurs at the
opposite edge, as distinguished from having such spurs in pairs exactly opposite
each other as heretofore.
All these features are employed by ine in one die roll but I also employ them
separately according to the particular form of my blank bars which may be

page_text: In the
ccompanying drawings,
Figure 1, in front view illustrates rolls embodying all of the features of my
present invention.
Figure 2, illustrates the working face of the die roll in plane projection.
For securing the best result, I employ two co-operative rolls, the die roll A, and
the roll B. The roll B is either grooved, or it is in substance, (as is common with
such rolls.) provided with a groove by means of collars adjustable or otherwise,
said groove being of proper width to correspond with the width of blank bars
desired, and said two rolls are geared together. The die roll A possesses several
novel features, and inasmuch as it may be employed with fairly good results with
a reciprocating grooved bed or table, my invention is not to be restricted to the
combination of said die roll with a co-operating roll.
My die roll is novel in that it has a zig-zag grooving tongue a, which inclines to
and fro with respect of the edges of the working face of the roll. In its best form
said tongue has a varied sectional contour, being broadly beveled, as at a² and
having a narrow bevel as at a and each two of its peripheral inclined portions
equals in length, the length of the horse shoe blank desired. The broad bevels
are located at the inner side of each two angles or lateral inclinations, thus
affording a broad bevel on the blank, at the inner side of its toe portion. The
narrow bevels are located at the outer side of each two angles for affording narrow
bevels on the heel portions or ends of each blank. In some cases the grooving
tongue is made quite thin and uniform in its sectional contour, this variation
constituting no departure from certain portions of my invention. This grooving
tongue also performs the function of so for dividing the blanks of one series in a
bar from those of the other, that a zig-zag slitting machine can readily cut through
the thin metal at the bottom of the groove. Even if this die roll should have on
its working face only a zig-zag grooving tongue, the roll would possess practical
value for the production of tapered blanks to be creased by hand or by separate
tools, as in a drop press.
My said die roll has also two series of nail scores which are arranged in a
novel manner in pairs, which in one serice alternate in position with the pairs of
creasers in the other series, as distinguished from having, as always heretofore, two
series with the creasers of each directly alongside of those in the other series.
This peculiar arrangement of the creasers in my roll causes them to properly
locate nail scores or creases in a bar wherein the blanks are tapered both ways
from the centre to the ends, and lie in the bar, with two heel portions, or ends of
two blanks, opposite the central or toe portion of a laterally adjacent blank.
Inasmuch as the variably beveled zig-zag grooving tongue is of special value in
forming blanks for high grade shoes, and as a grooving tongue need not be
employed at all for developing blanks for plain toe weighted shoes, it will be
obvious that a roll having only the peculiar creasers described, will possess practical
value.
My said die roll is further novel in connection with the arrangement of the heel
working spurs, which are in two series e and c', and instead of having as heretofore
the
spurs of one series exactly opposite those in the other series, they alternate in
position with each other, so as to define the lengths of blanks, in two lines, in a
bar wherein opposite each toe portion, there are two heel portions of two laterally
adjacent blanks. These heel marking spurs or studs may alone be relied upon for
forming the simplest form of blank bar containing metal so rolled and proportioned
that by means of suitable cutting or shearing tools, the bar may be readily
converted into separate plain tapered blanks, the heel marks in the bar, as made
by said studs or spurs, serving as reliable gauge marks during the angular cutting
operation.
For obtaining the most satisfactory results, however, in the production of blank
bars containing plain tapered blanks, a roll having the nail creasers and the heel
studs, should be employed. It will, however, be observed that inasmuch as the
location of the nail scores in a blank bar will always be uniform, each nail creaser

page_text: when provided with the usual nail head points d, will afford depressions in the blank
which can serve a good purpose for properly gauging each blank in a bar, with
relation to such blank cutting mechanism, as is required for developing plain tapered
horse shoe blanks.
It is sometimes deemed desirable to crease a blank throughout its length, and
such a variation in the character of the creasers would involve no departure from
certain portions of my invention, because the continuous nail creasers, as indicated
in dotted lines in Figure 2, would still have those portions thereof, for the reception
of nail heads arranged in pairs as described, even if the head points d were not
present, but if the latter were present, the embodiment of this portion of my
invention would only be still more apparent. The usual object of the crease in a
horse shoe is to properly house the nail heads, but in some varieties of shoe, a
continuous wide deep crease is provided, not only for housing the nail heads, but
also for affording a peculiar cutting or holding effect in contact with the ground, and
it is therefore to be understood that my die roll, may be widely varied with respect
of the character and arrangement of the nail creasers, without departing from certain
portions of my invention, in accordance with which the first die roll has been produced
which is capable of developing double blank bars containing tapered blanks for
making toe weighted shoes.
Having now particularly described and ascertained the nature of this invention,
and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is :-
First. A die roll for forming bars containing toe weighted horse shoe blanks, having
adjacent to each edge of its working face, a series of nail score creasers, arranged
in pairs, and with the pairs of creasers in either series, alternating in position with
the pairs in the other series.
Second. A die roll for forming tapered horse shoe blanks in bars having a zig-zag
grooving tongue, which at its periphery for a distance equal to the length of blank
desired, is inclined to and fro with respect of the edges of the working face of
the roll.
Third. In a die roll, a zig-zag grooving tongue which is variably beveled at its
sides, substantially as described, for variably beveling one edge of each horse shoe
blank, in a blank bar.
Fourth. In a die roll for forming tapered horse shoe blanks, two series of heel
making studs or spurs, located at the edges of the working face of the roll, and
having the spurs of either series, alternating in position with those of the other
series, the distance between the spurs in each series being equal to the length of
blank desired.
Fifth. A die roll for fonning bars containing the weighted horse shoe blanks
having the two series of nail creasers arranged in pairs, the pairs in one series
alternating in position with those of the other series, and also having a zig-zag
grooving tongue located between the two series of creasers.
Sixth. A die roll (for forming bars containing toe weighted horse shoe blanks)
having a zig-zag grooving tongue located between the edges of the working face of
the roll, and two series of heel making studs or spurs located at the edges of said
face, the studs in one series alternating in position with those in the other series
for defining the length of the blanks.
Seventh. A die roll, having between the edge of its working face, a zig-zag
grooving tongue, two series of nail creasers, and two series of heel making studs
or spurs.
Eighth. A die roll having a zig-zag grooving tongue which at its periphery
inclines to and fro once within the length of a horse shoe blank in combination with
a grooved co-operating roll.
Ninth. A die roll having a zig-zag grooving tongue, and two series of nail
creasers arranged in pairs, the pairs in one series alternating in position with those

page_text: in the other series, in combination with a grooved co-operating roll, substantially as
described.
Tenth. In combination with a grooved roll, a die roll co-operating therewith,
provided with a zig-zag grooving tongue, two series of nail creasers and two series
of heel making studs substantially as described.
