IMPROVEMENTS IN MACHINERY OR APPARATUS TO BE USED IN MANUFACTURING HORSE SHOES
Year: 1878

page_text: LETTERS PATENT to Henry Hunt, of Horsforth, in the County of York,
Smith, for the Invention of "IMPROVEMENTS IN MACHINERY OR APPARATUS
TO BE USED IN MANUFACTURING HORSE SHOES."
PROVISIONAL SPECIFICATION left by the said Henry Hunt at the Office of
the Commissioners of Patents on the 27th November 1878.
HENRY HUNT, of Horsforth, in the County of York, Smith.
"IMPROVEMENTS
IN MACHINERY OR APPARATUS TO BE USED IN MANUFACTURING HORSE SHOES."
This Invention relates to machinery or apparatus for bending a bar of suitable
section to the form required, such bar being previously cut to the proper length by
an ordinary shearing machine or otherwise.
The bar of iron of suitable length to form one shoe is whilst in a highly heated
state placed in the bending machine or apparatus, which consists of a circular
revolving table suitably driven by hand or power, and having attached thereto or
mounted thereon a "form" or "block" of the figure of the inside of the required
shoe.
The bar is placed on the table while the machine or apparatus is in a state of
rest.
On the machine or apparatus being set in motion the bar is by gripping apparatus
pressed and held securely against the "form" or "block." The gripping apparatus is
operated by a cam fixed beneath or behind the revolving table; this cam is so formed
as to hold the bar until the bending is completed, and to release the bar on completion
of the bending operation. During the process of bending the hot bar is pressed up to
and against the "form" or "block" by a roller applied to the outside of the bar
and actuated by a suitably arranged lever or levers.
On completion of the bending operation and release of the bent bar by the
gripping apparatus the roughly formed shoe is, whilst yet in a hot state, grooved,
punched, aud finished, it may be by hand in the usual way, or otherwise.

IN MACHINERY OR APPARATUS TO BE USED IN MANUFACTURING HORSE SHOES."
This Invention relates to machinery or apparatus for bending a bar of suitable

an ordinary shearing machine or otherwise. The bar of iron of suitable length to
form one shoe is, whilst in a highly heated state, placed in the bending machine or

set in motion the bar is by gripping apparatus

This cam is so formed as to hold the bar until the bending is completed, and to
release the bar on completion of the bending operation. During the process of
bending the hot bar is pressed up to and against the "form or "block" by a roller
applied to the outside of the bar and actuated by a suitably arranged lever or levers.
My improved machine is illustrated in the accompanying Drawings, where A, B, is
the principal framework, on which is mounted and fixed a cam C, above which, and
recessed into it, is the revolving table D; on this table is fixed the "form" or
"block" E of the same configuration as the inside of the required shoe. On said
revolving table D is a gripping apparatus or cramp F with its stud G, and runner
or bowl H, taking into and free to move in the recessed cam C, by which (on motion
being imparted to the table D) the said gripping apparatus F, G, H, is caused to
slide towards the "form or "block" E. The cam C, table D, "form" E, and
gripping apparatus F, G, H, are shewn to a larger scale in Figs. 4, 5, and 6.
is a section through the line Z, Z, of Figs. 4 and 6. The same letters are used to
describe the same parts as in Figs. 1, 2, and 3.
"
Fig. 5
The revolving table D is driven by suitably arranged gearing I, J, K, L, M, N;
with the fly wheel O and the handle P. When intended to be driven by power I
use in lieu of the handle P the fast and loose pulleys Q, R, (shown in dotted lines
in Figs. 1, 2, and 3) which receive a driving band from an ordinary motor in the
usual way. The heated bar S is placed in position on the table while the machine
or apparatus is at rest, with one end up against the adjustable gauge T. On the
machine being set in motion the action of the fixed cam C on the bowl or runner H
in connection with the gripping cramp F forces the said gripping cramp nearer the
centre of motion, so that it presses the heated bar S and holds it tightly against the
"form" E. During the revolution of the table D and the "form" E the bar S is
continually pressed against the said "form" E by the aforesaid gripper F and by
the handle or lever U and bowl V until the bending is completed, when the action
of the cam C at the point C¹ on the bowl or runner H releases the hold of the
cramp F and the roughly formed shoe is taken off and while yet in a hot state is
grooved or fullered, punched and finished either by hand in the usual way or
otherwise.
Having now particularly described the nature of my said Invention, and explained
the manner of carrying the same into practical effect, I wish it to be understood that
under the above in part recited Letters Patent I claim the constructing and

Drawings.

In witness whereof, I, the said Henry Hunt, have hereunto set my hand
and seal, this Twenty fourth day of May, in the year of our Lord One
thousand eight hundred and seventy nine.
