Improvements in Die Rolls for Making Side Weighted 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 be
particularly described and ascertained in and by the following statement :-
This invention relates to die rolls for making side weighted horse shoe blank
bars.
A characteristic feature in a die roll embodying my present invention is a
grooving tongue which projects from the working face of the roll, and is in
substance divided into working sections, each of which is as long as the horse shoe
blank desired, and which at one end is located nearer to the edge of said face than
the other end of said section, so that said tongue section can define or shape the
inner edge of horse shoe blanks which are wide at one end, and narrow at the other,
the same being adapted for use in the manufacture of side weighted horse shoes
substantially uniform in thickness, but having sides of unequal weight and area of
tread surface.
Die rolls provided with a grooving tongue as described may be organized to
produce blank bars containing one or more lines or rows of blanks as described in
an application of even date herewith.
In the manufacture of bars containing side weighted horse shoe blanks in double
lines, the bars are capable of being divided on longitudinal lines into single line
blank bars, and with one form of double line bar, the blanks in each single line bar,
are consecutively "rights" and "lefts" and in another form, the blanks in each
single line bar are either all "rights," or all "lefts," notwithstanding the fact that
in both forms of double line blank bars, each two blanks as they lie side by side in
the bar, constitute a true pair of blanks one being a "right" and the other a "left."
The die rolls devised by me for producing these two forms of double line blank bar,
are so far precisely alike that both rolls have a working face which on its curved
periphery (to an extent corresponding to the length of the desired blank) is
provided with a grooving tongue which is straight and for a part of its length is
located centrally on said face, and for another portion of its length is bifurcated,
or branched, or inclined in two directions, or toward the two outer edges of said
face, and a roll having such a tongue constitutes an important feature of my
invention.
The tongued roll co-operating with a guiding support, preferably a suitably,
grooved roll, in working upon a suitable stock bar of metal, forms by the action of
the central straight portion of the tongue, the inner edges of the wide portions of
a pair of blanks, side by side, and with its inclined portions it forms the inside edges
of the tapered portion of the same blanks, leaving certain intervening portions of
waste metal or scrap.
With two or more of said tongues consecutively repeated on the face of a roll,
and constituting a substantially continuous tongue, the best results accrue by forming
the tongue in alternately straight and alternately reversely inclined portions,
because then the double line bar will contain blanks which are in "right", and
"left" pairs, when the bar is divided laterally between the ends of the blanks, and
when divided longitudinally into single line bars the blanks will be successively
rights" and "lefts." My rolls are also provided with creases for forming nail
،،

page_text: bead scores, and usually with spurs, at or between the working sections of the
tongue, for indicating the end parting lines between the blanks.
If the die rolls are to be adapted to form single line blank bars, instead of the
double line bars, the working face of the roll is correspondingly lessened in width,
and the blanks are formed only at one side of the tongue.
In the accompanying drawings:
:-
Figure 1 in front view illustrates a pair of rolls, the upper one being a die roll,
embodying the special features of my invention in their best form.
Figure 2 illustrates the face of the die roll Figure 1, in plane projection.
Figure 3 in front view, illustrates a pair of rolls, the die roll of which is like
that in Figure 1 except as to the consecutive arrangement of those portions of the
tongue which correspond to the length of the blanks to be produced.
Figure 4 illustrates the face of the die roll of Figure 3, in plane projection.
It will be understood that some suitable guiding support for a metal stock bar
will be essential for co-operating with a die roll, and that a roll A with its groove a,
will afford the best results, whether the groove he formed in solid metal or located
between collars in a manner well known.
The die rolls Band B' will be first described, with respect of those features
which they possess in common. As shown in Figures 1 and 3 and in 2 and 4, ench
roll has a peripheral working face which appropriately corresponds with the width
of the groove d.
The said working face is provided with a projecting grooving
tongue which has its straight portion centrally located on said face, and is at 61
bifurcated, thus affording two other portions of the tongue as at 62 63 which are
respectively inclined toward the two edges of the face of the roll, each straight or
central portion, with its two branches or inclined portions, corresponding to or being
within the length of the blank desired, and constituting a complete working section
of the tongue. The top of said tongue is sharp and well defined, so that it will in
operation penetrate nearly to the thickness of the metal stock bar to be operated
upon. The cross sectional contour of the grooving tongue is varied in each case
according to the particular form of groove desired, this being varied with respect
of bevelling its sides, the latter being the inside edges of the blanks, which in some
cases are quite flatly bevelled, and in others only enough to secure good penetrating
effect by the tongue, as well as desirable strength thereof.
At the V space e between the inclined portions of the tongue 2 and 3, the
construction of the roll may be indefinitely varied, the principal thing to be
considered being the easiest possible working of the roll, coupled with leaving at
said ▼ portion as little bulk of waste metal as may be possible. As here shown the
sides of the tongue are quite flatly bevelled for producing blanks and shoes of a
desirable form.
"
With this symmetrical construction of the grooving tongue both rolls will
develop right and "left" pairs of blanks, side by side in the bar, and when
further extensions or prolongations of said tongue are provided on the face of a
roll it will depend upon their special arrangement, whether when a double blank
bar is longitudinally divided into single line blank bars, the blanks will either be
consecutively right and "left" or all of a kind in each bar.
::
When the face of the roll is provided with a continuous tongue which at intervals
is straight and located centrally on said face, and has its intervening portions
reversely inclined from and toward the centre of the face as shown in Figures 1
and 2, the inclined portions 623 of one part of the tongue, merge with succeeding
corresponding portions, and it follows that the blanks produced thereby will not
only be in pairs, side by side, but the blanks in cach line will be consecutively
rights" and "lefts." With this construction of the continuous groove, the
V spaces at ee are merged at their wide ends and the main portions of the waste
metal are therefore in narrow pieces tapered at both ends.
66

The two straight or central portions of the tongue bb, are in line, as shown, but
they are preferably enlarged. At their abutting ends by a flat faced spur d, which is
relied upon in part to define the wide ends of the blanks, but mainly to secure a

page_text: desirable shape to the inner sides of the wide portions of a blank corresponding with
the inner sides of the wide heels of "right" and "left" horse shoes formed from
said blanks.
"
Now on referring to Figures 3 and 4, it will be found that one end of the straight
central portion of the tongue is shown to be adjacent to the ends of the two
inclined portions 263 and consequently the blank bar formed by this die roll, will
have each of its longitudinal lines of blanks of one kind, or in other words, either
all "rights or all "lefts." In the matter of causing waste metal, there is little
difference between the working results of these two rolls, but inasmuch as blank
bars for sale in the open market will preferably be in single line thus leaving the
waste at the rolling mill, it is obviously desirable that the blanks in each bar should
be alternately. "rights" and "lefts." If however, special machines and tools be
used for forming the "right." blanks into shoes, and others for working the "left"
blanks, it will be generally desirable to have the roll like Figures 3 and 4 for
producing double line blank bars, which on being divided longitudinally into single
line bars will require no special assortment of the blanks when separated from
each other.
It is to be distinctly understood that a roll having on its face the straight and
furcated grooving tongue, constitutes the most important portion of my invention,
regardless of the form which may be given to those portions of the roll, which I
have called the V-space between the inclined or furcated portions of the tongue,
because it is the outerside of said straight and inclined portions of the tongue that
perform the prime service intended and the other portions of said tongue are relied
upon merely for restricting waste metal.
It will be seen, as hereinbefore indicated, that each central portion of the
grooving tongue with its appropriate inclined portion or portions constitutes a
complete working section of the tongue, and consequently it is obvious that if either
of the double line die rolls shown, should be divided on a line substantially parallel
with the centre of the portions b, the so reduced roll would be adapted to cooperate
with a roll having a correspondingly narrower groove in directly producing single
line blank bars, which as before indicated, could contain blanks, either consecutively
rights" and "lefts," or the blanks in each bar could be either all "lefts" or all
rights," according to the manner of arranging the ends of the complete working
sections with relation to each other, and such a single line roll, or any roll provided
with such tongue sections, would embody the main and characteristic feature of my
invention.

Blanks produced by the rolls as thus far described, may be subsequently provided
with the usual creases or scores for nail heads, but it is of course preferable to have
this operation performed by the die rolls, and therefore cach is provided with
appropriate nail scorers or creases which are here shown to be in different lengths,
as at e and e', the former having four nail head prints e³, and the latter but three,
thus providing for a shoe to be secured on a hoof with less nails at its narrow or
light side than at its wide or heavy side. It will be seen that these creasers or
scorers e and e¹ are in two rows, and that if they were continuous, as is sometimes
desired, it would in no matter affect the remainder of the roll, although of course,
the number and location of the nail head prints need not then be increased. For
defining the end lines of blanks, I further provide the rolls with spurs ƒ in
appropriate positions at or near both edges of the roll.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed as communicated to me by my
foreign correspondent, 1 declare that what I claim is :-
First. In a die roll for producing blanks for use in the manufacture of side
weighted horse shoes, a grooving tongue which projects from the working face of
the roll, and is in substance divided into working sections, each as long as the
blank desired, and having one end of each of said sections located nearer to the
edge of said face than the other end, substantially as described, for forming and

page_text: shaping the inner edges of horse shoe blanks, which are wider at one end than at
the other.
Second. A die roll, substantially as hereinbefore described for forming blank
bars containing two lines of side weighted horse shoe blanks, said roll having a
working face provided with a grooving tongue which within the length of a blank
is in part straight and centrally located on said face, and is in part bifurcated or
inclined from one end of said central portion toward both edges of said face.
Third. A die roll, substantially as hereinbefore described for forming blank bars
containing two lines of side weighted horse shoe blanks, said roll having a working
face provided with a continuous grooving tongue, which at intervals and for portions
of its length is located centrally in said face, and at one end of each central portion
is reversely inclined from and toward the centre of the face.
Fourth. A die roll, substantially as hereinbefore described for forming blank
bars containing two lines of side weighted horse shoe blanks, said roll having a
working face, provided with appropriate creasers and with a grooving tongue which
is in part straight and centrally located on said face and in part inclined outwardly
from one end of said central portion toward both edges of said face:
on
Fifth. The combination with a grooved roll, of a die roll having a working face
corresponding in width with the width of the groove in said roll, and having o
said face a projecting grooving tongue, which is divided into complete working
sections each as long as a horse shoe blank, and having one end of each section
located nearer the edge of said working face than is the other end of the section,
substantially as described.
