"AN IMPROVEMENT IN THE MANUFACTURE OF HORSE-SHOES BY MACHINERY."
A communication from abroad by James A. Burden, of the City of Troy, in the
County of Rensselaer, and State of New York, United States of America.
This Invention, communicated to me by Mr. Burden, relates to the manufacture of
horse-shoes by passing rolled bars of iron through machines which cut off portions
of said rolled bars of the proper length, and bend the same into the proper shape to
form horse-shoes.
It has been found by experience that to make a practical and successful horse-
shoe by the mode referred to the bars must be taken from the rolls and fed to the
cutting and bending machine before cooling and while in a highly heated state.
To make a good shoe the angles or corners of the bar must be sharp and well
defined. If a bar reduced by rolling to the proper size for a horse-shoc is allowed
to become cold and is then reheated, the angles of the bar will be melted or burned
off before the interior has become sufficiently heated to be submitted to tho
operation of the horse-shoe machine, so that as above stated the bar can only be
used before cooling and while still highly heated; but in using the bar in this
condition another difficulty is encountered which it is the object of this Invention
to obviate.
It has been found that in passing through the rolls which are kept constantly
chilled by water dropping on them the bar becomes unequally heated, that is to
say, the exterior which is in actual contact with the rolls becomes cooled or chilled,
so that it is much more solid than the interior of the same bar, the result is that
different parts of the bar oppose an unequal resistance to the bending force, and the
shoes so made are imperfect and defective. I obviate this difficulty by the use of
an intermediate furnace between the rolls and the horse-shoe machine after the bar
of iron has been reduced to the proper size and shape by passing through the rolls,

passing through this furnace the exterior of the bar is reheated, and the whole bar

"AN IMPROVEMENT IN THE MANUFACTURE OF HORSE-SHOES BY MACHINERY." (A.
communication from abroad by James A. Burden, of the City of Troy, in the County
of Rensselaer, and State of New York, United States of America.)
This Invention, communicated to me by Mr. Burden, relates to the manufacture of
horse-shoes by passing rolled bars of iron through machines which cut off portions
of said rolled bars of the proper length, and bend the same into the proper shape
to form horse-shoes.
It has been found by experience that to make a practical and successful horse-
shoe by the mode referred to the bars must be taken from the rolls and fed to the
cutting and bending machine before cooling and while in a highly heated state.
To make a good shoe the angles or corners of the bar must be sharp and well
defined. If a bar reduced by rolling to the proper size for a horse-shoe is allowed
to become cold and is then reheated the angles of the bar will be melted or burned
off before the interior has become sufficiently heated to be submitted to the operation
of the horse-shoe machine, so that, as above stated, the bar can only be used before
cooling and whilo still highly heated; but in using the bar in this condition another
difficulty is encountered which it is the object of this Invention to obviate.
It has been found that in passing through the rolls which are kept constantly
chilled by water dropping on them the bar becomes unequally heated, that is to
say, the exterior which is in actual contact with the rolls becomes cooled or chilled.
so that it is much more solid than the interior of the same bar; the result is that
different parts of the bar oppose an unequal resistance to the bending force, and the
shoes so made are imperfect and defective. I obviate this difficulty by the use of
an intermediate furnace between the rolls and the horse-shoe machine after the bar
of iron has been reduced to the proper size and shape by passing through the rolls,.
and while it is still highly heated I pass it slowly through such intermediate furnace,
and from the furnace directly into the cutting and bending machine. By passing,
through this furnace the exterior of the bar is reheated, and the whole bar brought,
to a uniform temperature, thus obviating the defects above mentioned.
I do not confine myself to a furnace of any particular shape or size, but it should,
be of such a length that the exterior of the bar will be sufficiently heated by passing
through the furnace at the ordinary rate of speed at which such bars can be fed to
the cutting and bending machine.
In the accompanying Drawings Figure 3 is a representation of the rolls through
which the bars of horse-shoe iron are passed to reduce them to the proper size and
shape; Figure 2 is a plan of machinery shewing one mode of applying the Invention ;.
and Figure 1 is a section of said machine through the lines G, G
In Figs. 1 and 2 C represents an elevated trough on which the bars are laid as
they come from the rolls D; B is the intermediate furnace; and A is the cutting
and bonding machine.

page_text: The operation of the Invention is as follows:-The bars of iron are rolled to the
proper size in the train D, they are then placed on the trough or guide C. A work-
man with a pair of tongs seizes the bar at H and pushes it along the trough into
the furnace B, another workman seizes the end of the bar at K and pushes it into
the cutting and bending machine A. The furnace B is fired at doors L, L.
It will be seen that as one bar follows another their rate of progression through
the furnace will be the same as that at which they can be fed into the cutting and
bending machine.
Having described the nature of the said Invention, and explained the manner of
carrying it into practical effect, as communicated to me as aforesaid, I hereby declare
that what I consider to be novel and original and therefore claim as the Invention
secured to me by the herein-before in part recited Letters Patent is, the above
described improvement in the manufacture of horse-shoes by machinery, consisting
in passing the horse-shoe bars after they have left the rolls and while they are still
highly heated through an intermediate furnace, and thence into the cutting and
bending machine, substantially as and for the purposes specified.
In witness whereof, I, the said William Lloyd Wise, have hereunto set my
hand and seal, this Twenty-first day of July, in the year of our Lord One
thousand eight hundred and seventy-seven.
