page_text: LETTERS PATENT to Alfred Vincent Newton, of the Office for Patents,
66, Chancery Lane, in the County of Middlesex, Mechanical Draughts-
man, for the Invention of "IMPROVED MACHINERY FOR MAKING HORSE
SHOES." A communication.
-
Sealed the 21st May 1858, and dated the 13th March 1858.
PROVISIONAL SPECIFICATION left by the said Alfred Vincent Newton
at the Office of the Commissioners of Patents, with his Petition, on the
18th March 1858.
I, ALFRED VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane,
in the County of Middlesex, Mechanical Draughtsman, do hereby declare the
nature of the said Invention for "IMPROVED MACHINERY FOR MAKING HORSE
SHOES," to be as follows:-
This Invention relates to a novel arrangement of machinery whereby bar
iron is cut into lengths bent to a horse shoe form, and impressed between.dies
to complete the horse shoe in a rapid succession of operations.
The machine is provided with a fixed and moveable die, the former of which
is firmly secured to the framing while the moveable die is attached to the
front end of a plunger which slides through housings in the framing. The
moveable die is the swaging surface for forming the top of the shoe; it sur-
rounds a projection or former of wrought iron extending about two inches in
front of the die, and corresponding in shape to the interior of the shoe.

page_text: Immediately opposite to the front end of the plunger is fixed the swaging
face which forms the bottom of the shoe. Surrounding the fixed swaging face
is a box plunger, which slides through housings, and works clear of the swaging
face and of an abutment bar that supports it.
The fixed die corresponds precisely with the shape of the bottom of the shoe
except where the crease and nail holes occur; these are afterwards made by
suitable appliances attached to the interior of the hollow sliding box. The
bending of the red hot bar (from which a suitable length to form a horse shoe
is cut after every operation of the machine) is effected by levers which slide
up and down on a pair of vertical guides. At their lower extremities these
levers carry small friction rollers which press upon the piece of heated iron,
and as they descend lap it around the central former, the compressing motion
of the lower rollers being effected by a cam piece, against which a pair of
rollers carried by the upper ends of the levers press. When the bar is bent
into the proper shape, the moving die advances and presses it between the dies,
thus shaping it on the face and back.
The next operation is the creasing and punching, which is effected by the
advance of the box, which completes the manufacture; the moving parts now
retire, and the shoe is discharged from the machine.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alfred Vincent Newton in the Great Seal Patent Office on
the 13th September 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALPRED
VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane, in the County
of Middlesex, Mechanical Draughtsman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of March, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Alfred Vincent Newton, Her special license that I, the said Alfred
Vincent Newton, my executors, administrators, and assigns, or such others as
I, the said Alfred Vincent Newton, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and at all
times thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IMPROVED

page_text: MACHINERY FOR MAKING HORSE SHOES," being a communication from abroad,
upon the condition (amongst others) that I, the said Alfred Vincent Newton,
by an instrument in writing under my hand and seal, should particularly
describe and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said Alfred Vincent Newton, do hereby
declare the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the fol-
lowing statement, reference being had to the Drawing hereunto annexed, and
to the letters and figures marked thereon (that is to say):
This Invention as communicated to me by my foreign correspondent relates
to a novel arrangement of machinery whereby bar iron is cut into lengths bent
to a horse shoe form, and impressed between dies to complete the horse shoe
by a rapid succession of operations.
In the accompanying Drawing, Fig. 1 represents in perspective view the
improved machine; and Fig. 2 is a view of a hollow box plunger removed
from the machine; Fig. 3, the plunger which carries the former, and one
swaging plate; Fig. 4 represents the interior of the end of the moving hollow
die box; Fig. 5 represents the stationary swaging plate which swages the
bottom of the shoe; Fig. 6 represents in front elevation the moving hollow
die box, fitting around the bottom swaging plate; and Fig. 7 is an inside view
of the same.
The machine consists of two heavy pieces of frame work A and B, solidly
and securely attached to a heavy cast-iron bed plate; C, C', is a heavy plunger
made of cast iron, sliding through the housing A. At its front end C', it has
a steel face d, d', raised on it precisely the shape of the horse shoe required to
be made; this constitutes one swaging surface for forming the top of the shoc.
The steel face d, d', surrounds a projection or former e, e¹, of wrought iron,
which extends about two inches in front of the steel face piece d, d, and is of
the same shape as the interior of the shoe.
Immediately opposite to the front end C of the swaging face d, d', there is
fixed another swaging face fff", which forms the bottom of the shoe.
This swaging face is made of steel, and is permanently fixed against a trans-
verse abutment bar G, G' (shewn at Fig. 2); H, H', is a hollow box plunger,
sliding through the housing B; this hollow box plunger slides so as to clear
the swaging face f, f, f", and the abutment bar G, G', by means of a slot
made in the hollow box plunger. The interior of the end H of this box

page_text: plunger presents the appearance shewn in Fig. 4, and it fits to and slides over
the fixed swaging face f, f, f", in the manner shewn in Fig. 5.
The fixed steel piece f, f, f", corresponds precisely with the shape of the
bottom of the shoe, except in the portion h, h', where the crease and nail holes
are afterwards made by the parts h and h', attached to the interior of the
hollow sliding box H, H; I, I', are cutters similar to those heretofore
used; K, K, and K", K, are bending levers, which slide up and down on
a pair of vertical guides. At the lower extremity of each lever is a small
friction roller 7, 7. These lower friction rollers r, r¹, press upon the piece of
heated iron, and as they descend force it to bend around the central former
e, e¹, the compressing motion of the lower rollers r, r, being effected by a cam
piece S, Fig. 1, against which the upper rollers 1, press. The plunger C, C³,
is moved forward by a cam M on one of the main shafts N, N', and it is
returned by a spring or reverse cam. The hollow box plunger H, H¹, is
moved forward by a spring or reverse cam. The upright levers K, K', and
Ku, K, are elevated and depressed by a pair of bell-cranks T, T, T
working in connection with a yoke W and cam V. This cam V is constructed
of the peculiar shape shewn in the Drawing, the effect of which in combination
with the yoke W is, that while the cam shaft V, V, revolves in the same
direction, a backward and forward motion is given to the lower end of the
bell crank T, T, T", and thence communicates both an upward and downward
motion to the bending levers K, K, and K", K. This mode of operating
the vertical bending levers in connection with the central stationary guide
cam S, produces a great efficiency combined with simplicity in the movements.
The cutter I is moved forward by a cam at N, and returned by a spring.
The operation of the several parts is as follows:-A bar of iron properly
heated is slidden over the top of the former e, e¹, until it strikes a stop on the
opposite side of the machine. The bending levers K, K', K", K", descend,
and just as they press upon the iron bar the cutter I moves forward and cuts
off the proper length, and the levers K, K¹, K", K", continuing their descent
bend the iron around the former e, e, el. The levers K, K¹, K", K, then
ascend, and the plunger C, C¹, moves forward, carrying the bent iron into the
hollow die box on the end H of the plunger H, H. The iron is thus swaged
between the moving-steel swager d, d', and also on all the lower side of the
shoe, except where the crease and nail holes are to be made. The hollow
box plunger H, H', now moves forward, and punches and creases the shoe and
finishes it on the edge, and the bottom side in that part where the creasing
and punching was done. As the hollow box moves forward against the sides
or outer edge of the shoe it gives it a complete and square finish. The hollow"

page_text: box H, H, then recedes and leaves the shoe on the former e, e¹, e¹¹. The
former and plunger C, C', then recede, and a discharging instrument shewn
detached at Fig. 8 being projected forward, pushes the finished shoe from the
former.
The advantage of this improved machine is, that the moving die box
travelling on the outside of the shoe while held between the swages, finishes
the edge of the shoe more perfectly than has been done heretofore. The
perfecting of the shape and form of the shoe by the operation of creasing and
punching, after it has been partially formed by swaging instead of creasing
and punching the shoe after it had been perfectly formed as heretofore done,
produces a more perfect shoe than any heretofore made.
Having now set forth the nature of the Invention of "Improved Machinery
for Making Horse Shoes," as communicated to me by my foreign corre-
spondent, and explained the manner of carrying the same into effect, I wish it
to be understood that under the above in part recited Letters Patent I
claim,―
First, the arrangement of the bending levers K, K', K", K, and cam S,
substantially as above described.
Secondly, the mode of forming and swaging the shoe by forcing it, while on
the former e, e', between the moving swager d, d', and the fixed swager
fff", and while enclosed at the side within a hollow moving die box H, H',
substantially as above described.
Thirdly, the finishing of the outside edge of the shoe, and the creasing and
punching of it at the same time by means of the hollow moving die box,
substantially as above described.
In witness whereof, I, the said Alfred Vincent Newton, have hereunto
set my hand and seal, the Tenth day of September, in the year of
our Lord One thousand cight hundred and fifty-eight.
