page_text: LETTERS PATENT to Hazen Jay Batchelder, of the State of Massachusetts,
of the United States of America, for the Invention of "A NEW AND
USEFUL INVENTION HAVING REFERENCE TO THE MANUFACTURE OF HORSE-SHOES
OR VARIOUS OTHER ARTICLES."
COMPLETE SPECIFICATION filed by the said Hazen Jay Batchelder at
the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 2nd August 1866, pursuant to the 9th Section of the
Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, BE IT KNOWN
that I, HAZEN JAY BATCHELDER, of the State of Massachusetts, of the United
States of America, have made "A NEW AND USEFUL INVENTION HAVING
REFERENCE TO THE MANUFACTURE OF HORSE-SHOES OR VARIOUS OTHER ARTICLES,"
and do hereby declare the nature of the same, and the manner in which it is
to be performed to be fully described in the following Specification and
represented in the accompanying Drawings marked Plates 1 and 2.
Figure 1 is a front elevation, and Figure 2 a longitudinal and vertical

page_text: section of a machine for rolling metal or converting it into blanks for making
horse-shoes; Figure 3 is an end view of it; Figure 4 is a side view of one
of the circular dies E, to be herein-after explained.
In the said Drawings of Plate 1 A denotes the frame of the machine;
B, B, are two horizontal and parallel shafts whose journals a, a, b, b, are
sustained in vertical sliding boxes D, D. When in their positions the upper
pair of such boxes rest on cross rods c, c, extending through the standards of
the frame. Screws d, d, screwed down through the capse of the standards
serve to regulate the height of movement of the upper boxes, and of course
that of the rolls applied to the upper of the shafts.
Each roll is composed of a series of annular dies or rollers E, E, E, E, E, E,
each of which is made in two semicircular parts h, h, see Figure 4. These
parts have lips f, f, projecting from their opposite sides, and encompass
the shaft B or C on which they may be placed, such lips being to enter
corresponding recesses 9, 9, made in rings G, G, or H, H, which also go
around the shaft. Furthermore each of the shafts B, C, is provided with
a channel i, extending around it close to the end of the first ring G, such
channel serving to hold two clasps N, N, formed as shown in side view in
Figure 5. These clasps are connected by screws k, k, and they serve with
the channel i, and shoulders l, l, formed on the shaft to keep the roll sections
in their places. The object of making each circular die of each shaft B; C,
in two parts h, h, and providing it with lips as described and using rings G, G,
and a channel i, and its clasps N, N, to the shaft is to enable either of the
dies to be readily removed from its shaft without requiring the removal of
any or all of the others. As the dies may need repair or to be removed for
other purposes, my improvement enables them to be separated from the
shaft or fixed in place thereon with great ease and facility in comparison to
what would be required were all the dies like the rings between their whole
circles. I and K are the gears fixed on the shafts B, C, and for the purpose
of causing the upper of them, with its dies, to be revolved with and by the
other. The lower shaft has two cams L, L, fixed on its journals; these
cams rest on the peripheries of friction wheels M, M, supported on centre
pins m, m, the whole being arranged as shown in the Drawings. These
cams as the shaft C revolves raise it at times, or impart to it proper
vertical movements necessary to cause the dies to impart to the bar of iron
the requisite variation of thickness. One of the rings H of the lower shaft
is represented as having a die P formed on its side in manner as shown in
Figures 2 and 6; the latter Figure being an inner side view of the said ring

page_text: H:. This die is for varying the width of the toe blank as may be necessary
from the toe to the heel of the horse-shoe. O is what is termed the
"creasing" die which is made like the other circular dies except that it is
to project beyond the die R, sufficiently to make the nail hole creases of the
horse-shoe blanks. This die O, with its adjacent die R, are formed in sections
as shown in Figure 2, and in ends views as, exhibited in Figures 7 and 8.
By revolving the lower shaft C the dies of both shafts will be put in motion
simultaneously.
1
I claim the mode of constructing each of the rolls, viz. not only with each
of its dies made in sections and with lips to each as described, but with
rings to encompass the lips, the said sections and rings being held in place by
a shoulder and a channel i and clamps N, N, or their equivalents, the
whole being substantially as and for the purpose specified.
I also claim the separate creasing die O, made as described in combination
with two of the rings H, H, and a sectional die R arranged between them,
the whole being as set forth.
I also claim the combination of the lateral die P for obtaining variation
of width of the blank with the two ring dies H, H, the E, O, and R, and
the mechanism for moving the roll shaft C vertically for the purpose of
effecting the variation of thickness of the blank, as described.
.
I also claim the arrangement of the cams L, L, and their supporting
wheels M, M, with the die shafts C, B, and their reducing rolls composed of
roller dies as set forth.
And my Invention further consists in mechanism or a machine for bending
iron for its conversion into a horse-shoe, and particularly after such iron may
have been prepared by the machine or mechanism herein-before described.
Plate 2. of the accompanying Drawings exhibits the said machine for
bending the iron.
i Of such Drawings, Figure 1 is a top view, and Figure 2 a longitudinal
and vertical section of such machine.
In the said. Drawings A denotes a former which is arranged on a bed
plate G, and shaped to correspond with the interior edge of a horse-shop.
This former is made or affixed to a pitman or slide B provided with a toothed
rack or series of teeth C to engage with a gear D. Such gear is duly
supported by a shaft B (sustained on standards b, b,) and has a. lever F
by which it may be revolved so as to impart to the pitman or slide and the
former A their forward and backward movements.
In advance of the said former and on the bed plate G are two bending on

page_text: curved levers H, H, which when in use turn horizontally on fulcra a, a,
projecting upward from the said plate. These levers by co-operating with
the former A, serve to bend a horse-shoe blank or metal bar' around the
edge of the said former so as to impart to such bar the form of a horse-shoe.
The shorter arms of the levers when such levers are opened or in positions to
receive a blank rest against abutments or adjustable stops c, c, arranged as
represented. The longer arms d, d; of the levers are curved towards each
other so that while the blank is in the act of being forced against them by
the former A the levers may be made to turn on their fulcra in a manner to
cause their longer. arms to gradually approach one another in a manner to set
the horse-shoe blank in a. line at its quarters and at the heels, and cause it to
conform to the shape of the forming edge of the part A. There may
friction rollers e, e, in the arms of the bending, levers, and there may also be
a spring to each bending lever, the said spring being so applied to it and
the bed plate as to force open the levers or press them into their proper
positions for the reception of a blank, which prior to being bent is to be placed
against the extreme ends of the longer arms of the levers, and so that the
former A during. its advance may first touch the blank at its middle. For
this purpose one end of the blank may be pressed, against a stop g fixed to
the bed plate.
For separating the blank from the former AI employ two dischargers
h, h, which are stationary abutments, against which the heels of the blank are
drawn by the pitman or slide B while it is in the act of being retracted and
after the blank may have been drawn away from the levers. The abutments
spring the blank off the former A, the elasticity of the quarters afterward
serving to restore the blank to or about to its proper shape.
In order to prevent the blank from curling or being bent laterally or
upward or downward at its toe during the process of bending such blank there
are two jaws i, k, projecting. from the, front end of the former A. These jaws
embrace the blank at its middle and on opposite faces of it or in other words
the. blank enters. between the said: jaws and they prevent it from being bent
either-up or down.
I claim the benders H, H, made and arranged in. combination. with the
spring fin manner and so as to operate with the former A, substantially as
described.
I also claim the combination. and arrangement of the jaws i; k, with the
former A, combined and to operate with the spring bending levers H, H,
substantially in manner as described.

page_text: I also claim the combination as well as the arrangement of the dischargers
h, with the former A, and the bending levers H, H.
In witness whereof, I, the said Hazen Jay Batchelder, have hereunto set
my hand and seal, this 17th day of July, in the year of our Lord
1866.
