"IMPROVEMENTS IN MACHINES FOR FINISHING NAILS FOR SHOEING HORSES AND
OTHER ANIMALS." A communication from abroad by John F. Haskins Engineer
of 1 Rue Laffitte Paris France.
The object of this Invention is to take punched nail blanks (which have been
preferably shaken in a drum with or without sawdust for the purpose of wearing
off the burrs and smoothing their edges) and by this machine cold roll draw and
elongate the shanks of the said blanks compress flatten and bevel their points, give
the proper curvature to the shank of the nail ultimately shearing the points by
means of any appropriate or well-adapted mechanism.
The improvements herein claimed consist,
Firstly In the use conjointly with two pairs of rolls having suitable die grooves
to draw and shape the nail blanks of a guide way located between the said two
pairs of rolls having within it a moveable side piece and externally a pivoted cover
plate combined with an intercepter released by the moveable side piece when it is
acted upon and moved by a nail blank which is improperly jammed into the guide
way or is crooked.
Secondly. In the combination with the rolls for operating upon the blank of bending
or setting mechanism to operate upon the side edges of the head of the blank and
cause it to move away from the rolls at such an inclination to the vertical lines

page_text: drawn through the axes of the rolls at each side af the guide way as will give to
the blank its proper curvature in the direction of the length of the blank this
bending mechanism giving a like curvature to each blank.
Thirdly. In a self-acting arrangement for liberating the component parts of the
said-bending-mechanism in case of any derangement and thereby arresting the
further feed of the blanks in the machine
=
Figure 1 represents in front elevation sufficient portions of a rolling machine to
illustrate the present improvements.
Figure 2 is a side elevation thereof the right-hand roll of the upper and lower
pairs of rolls being removed.
Figure 3 is a plan and front elevation of the guide way with its moveable side
piece and swinging cover located between the two sets of rolls the cover plate being
swung out of position, and
Figure 4 is a detailed plan of the bending or setting inechanism in operative
position the said mechanism being shown in Figure 1 as thrown open to more clearly
represent the construction of the parts.
The upper, set of rolls ³ ³ and the lower set of rolls ³ ³ are each provided at
their peripheries with suitable and usual die grooves the rollers a³ to act upon the
shank of the blank and draw and stiffen it without drawing or hardening the head
and the lower set 3 to flatten the small end of the blank and bevel it at its face so
that it may be subsequently sheared by a punch and die after passing through the
bending mechanism as heretofore practised.
In this machine a blank to be operated upon is dropped head first into the tube
or mouth-piece c³ from which it passes between and is acted upon by the rolls a
then the blank passes onward into and through the guide way ³ extended from
the set of rolls a³ to the set as shewn in the Drawings and from the said guide
way between the rolls b³.
One of the walls of the guide way is formed by a moveable side piece e³ swung
on a stationary pin a which enters a groove in the guide way block, see dotted
lines Figure 3 and the side piece is pressed into the guide way by a spring g³.
The guide way has a cover plate 3 pivotted to the guide way block at and is
provided at its outer face with a projecting pin. An intercepter ³ pivoted at 13
and provided with a tail piece m³ has a spring ³ to move the end of the intercepter
through a passage or opening at the side of the mouth-piece c³ as shown in dotted
lines.
When the machine is in operation the tail piece made as a spring is engaged with
a notch in the pin of the cover plate and the intercepter is held out as shown in
full lines Figure 2. Should the guide way become jammed or crowded with nail
blanks or be clogged with a crooked blank the side piece e³ will be moved laterally
against the spring and the pin 3 on the said side piece will then disengage the
tail piece from the pin and permit the spring ³ to throw the intercepter into the
mouth-piece and stop the further passage of blanks the tail piece then assuming the
position as in dotted lines after which the cover plate 3 may be swung round as in
Figure 3 and the accumulated or imperfect blanks removed.
Below the rolls is located the bending or setting mechanism which consists of
one or more, preferably two inclined sharp ribs or projections o³, 23, on blocks placed
immediately below the rolls ³ so that the side edges of the head of the blank as
the said head passes from the nip of the said rolls is acted upon by the said ribs the
cutting their way into the side edges of the head causing the head to be moved
laterally as the blank passes from between the said rolls which results in bending
or curving the said blank to the proper extent according to the length of the nail
and preventing the blank from being curved edgeways.
The degree of curvature of the blank depends upon the amount of inclination of
the ribs o³, p³.
The rib o³ is upon a block attached to the pivotted lever and a rib p³ on the
block attached to the stationary piece see Figure 4.
The lever is at one end hinged to the piece s³ and its other wedged-shaped end

page_text: is held in the closed position by a swinging piece 3 having a notch, which engages
with the wedged-shaped end of the lever A suitably placed spring ³ exerts
its force to keep the swinging piece 3 engaged with the end of the lever 3.
arm fixed on the lower end of the rod is held behind the end of the
lever 13.
An
away
If a blank shall become crooked below the rolls it will force the lever
from the portion s³, the spring u³ which holds the swinging piece t³ in the locking
position allowing for such motion. There, by the arm a, will be liberated and. the
rod *, which carries on its upper end, a second intercepter e will be partially turned
by a spiral spring surrounding the same, thus introducing the intercepter c
into the mouth-piece and stopping the passage of the nail blanks in the latter.
Having now described and particularly set forth the nature of the said Invention
and the manner of carrying the same into effect I would have it understood that
I am aware that it is not novel to employ in machines for finishing nails for shoeing
horses and other animals, two pairs of rolls having die grooves to draw and shape the
nail blanks, a guide way located between the said two pairs of rolls, such guide way
having within it a moveable side piece combined with an interceptor released by the
moreable side piece when the same is acted upon and moved by a nail blank which is
improperly jammed into the guide way, or is crooked; also that it is not novel to employ,
in connection with a guide way located between two pairs of drawing and shaping rolls, a
hinged gate opening outwards and combined with an interceptor released by the opening
outwards of such gate; likewise that it is not novel to employ a removeable front plate
and locking bar in connection with a guide way located between two pairs of drawing and
shaping rolls, and having within it a moveable side piece combined with and releasing an
interceptor, and I make no claim to any of such parts separately, or to any of the
combinations of such parts mentioned in this disclaiming clause, but that what I do
claim is
Firstly A guide way used conjointly with the two pairs of rolls, the latter having
suitable die grooves to draw and shape the nail blanks, the guide way being located
between the said two sets of rolls and having within it a moveable side piece and
externally a pivotted cover plate, combined with an intercepter, released by the
movable side piece to intercept the further passage of blanks to the rolls substantially
as set forth.
Secondly. The combination with one or more pair of rolls, of the bending or
setting mechanism, to operate upon the side edges of the head and direct the blank
positively as and for the purposes described.
Thirdly. The guide way used in connection with the two pairs of rolls which
draw and shape the nail blanks, in combination with a moveable side piece with an
intercepter released by the said side piece and with bending mechanism, such as
described to operate upon the nail head as and for the purposes set forth.
Fourthly. The combination with the bending mechanism of the auxiliary inter-
cepter and intermediate operating devices, to stop the passage of the blanks when
the bending mechanism is forced open.
In witness whereof I the said William Morgan-Brown have hereunto set
my hand and seal this Twenty-ninth day of October in the year of our Lord
One thousand eight hundred and seventy-eight.

COMPLETE SPECIFICATION filed by, the said William Morgan-Brown.at the
Office of the Commissioners of Patents on the 29th October 1878.
WILLIAM MORGAN-BROWN, of the Firin of Brandon and Morgan-Brown, Engineers
and Patent Agents, of 38, Southampton Buildings, London, and 1, Rue Laffitte, Paris.
"IMPROVEMENTS IN MACHINES FOR FINISHING NAILS FOR SHOEING HORSES AND
OTHER ANIMALS." A communication from abroad by John F. Haskins, Engineer,
of 1, Rue Laffitte, Paris, France.
The object of this Invention is to take punched nail blanks (which have been
preferably shaken in a drum with or without sawdust, for the purpose of wearing
off the burrs and smoothing their edges), and by this machine cold roll draw and
elongate the shanks of the said blanks, compress, Hatten, and bevel their points, give
the proper curvature to the shank of the nail, ultimately shearing the points by
means of any appropriate or well-adapted mechanism.
The improvements herein claimed consist,-
Firstly. In the use conjointly with two pairs of rolls, having suitable die grooves
to draw and shape the nail blanks of a guide way located between the said two
pairs of rolls, having within it a moveable side piece and externally a pivoted cover
plate, combined with an intercepter released by the moveable side piece when it is
acted upon and moved by a nail blank which is improperly jammed into the guide
way or is crooked.
Secondly. In the combination with the rolls for operating upon the blauk of bending
or setting mechanism to operate upon the side edges of the head of the blank, and
cause it to move away from the rolls at such an inclination to the vertical lines

page_text: drawn through the axes of the rolls at each side of the guide way as will give to
the blank its proper curvature in the direction of the length of the blank, this
bending mechanism giving a like curvature_to_each_blank..
-Thirdly. In a self-acting arrangement for liberating the component parts of the
said bending mechanism in case of any derangement, and thereby arresting the
further feed of the blanks in the machine.
Figure 1 represents in front elevation sufficient portions of a rolling machine to
illustrate the present improvements.
Figure 2 is a side-elevation-thereof; the right-hand roll of the upper and lower
pairs of rolls being removed.
Figure 3 is a plan and front elevation of the guide way, with its_moveable-side-
-piece-and-swinging cover located between the two sets of rolls, the cover plate being
swung out of position, and
Figure 4 is a detailed plan of the bending or setting mechanism in operative
position, the said mechanism being shown in Figure 1 as thrown open to more clearly
represent the construction of the parts.
The upper set of rolls a³, a³, and the lower set of rolls 63, 63, are each provided at
their peripheries with suitable and usual die grooves, the rollers as to act upon the
shank of the blank and draw and stiffen it without drawing or hardening the head,
and the lower set 63 to flatten the small end of the blank and bevel it at its face, so
that it may be subsequently sheared by a punch and die after passing through the
bending mechanism, as heretofore practised.
In this machine a blank to be operated upon is dropped head first into the tube
or mouth-piece c³, from which it passes between and is acted upon by the rolls a³,
then the blank passes onward into and through the guide way d³ extended from
the set of rolls a³ to the set b³, as shewn in the Drawings, and from the said guide
way between the rolls bs.
One of the walls of the guide way is formed by a moveable side piece e³ swung
on a stationary pin x, which enters a groove in the guide way block, see dotted
lines, Figure 3, and the side piece is pressed into the guide way by a spring g³.
The guide way has a cover plate h³ pivotted to the guide way block at 3, and is
provided at its outer face with a projecting pin 3. An intercepter 1, pivoted at 13
and provided with a tail piece m³, has a spring n³ to move the end of the intercepter
through a passage or opening at the side of the mouth-piece c³, as shown in dotted
lines.
When the machine is in operation the tail piece made as a spring is engaged with
a notch in the pin of the cover plate, and the intercepter is held out as shown in
full lines, Figure 2. Should the guide way become jammed or crowded with nail
blanks, or be clogged with a crooked blank, the side piece e³ will be moved laterally
against the spring g³, and the pin f3 on the said side piece will then disengage the
tail piece from the pin j³, and permit the spring ³ to throw the intercepter into the
mouth-piece and stop the further passage of blanks, the tail piece then assuming the
position as in dotted lines, after which the cover plate h³ may be swung round, as in
Figure 3, and the accumulated or imperfect blanks removed.
Below the rolls 63 is located the bending or setting mechanism, which consists of
one or more, preferably two, inclined sharp ribs or projections o³, 23, on blocks placed
immediately below the rolls b³, so that the side edges of the head of the blank as
the said head passes from the nip of the said rolls is acted upon by the said ribs, the
cutting their way into the side edges of the head causing the head to be moved
laterally as the blank passes from between the said rolls 63, which results in bending
or curving the said blank to the proper extent, according to the length of the nail,
and preventing the blank from being curved edgeways.
The degree of curvature of the blank depends upon the amount of inclination of
the ribs o³, p³.
The rib o is upon a block attached to the pivotted lever ³, and a rib 2³ on the
block attached to the stationary piece 83, see Figure 4.
The lever is at one end hinged to the piece 83, and its other wedged-shaped end

page_text: is held in the closed position by a swinging piece 3, having a notch which engages
with the wedged-shaped end of the lever 7 A suitably placed spring u³ exerts
its force to keep the swinging piece t³ engaged with the end of the lever; an
arm a fixed on the lower end of the rod b is held behind the end of the
lever 3.
If a blank shall become crooked below the rolls bs it will force the lever away
from the portion 3, the spring u³ which holds the swinging piece ³ in the locking
position allowing for such motion. Thereby the arm a will be liberated, and the
rod b, which carries on its upper end a second intercepter c, will be partially turned
by a spiral spring surrounding the same, thus introducing the intercepter c¹
into the month-piece and stopping the passage of the nail blanks in the latter.
Having now described and particularly set forth the nature of the said Invention
and the manner of carrying the same into effect, I would have it understood that
what I claim is,-
Firstly. A guide way used conjointly with the two pairs of rolls, the latter having
suitable die grooves to draw and shape the nail blanks, the guide way being located
between the said two sets of rolls and having within it a moveable side piece and
externally a pivotted cover plate, combined with an intercepter released by the
movable side piece to intercept the further passage of blanks to the rolls, substan-
tially as set forth.
Secondly. The combination with one or more pair of rolls of the bending or
setting mechanism to operate upon the side edges of the head and direct the blank
positively as and for the purposes described.
Thirdly. The guide way used in connection with the two pairs of rolls which
draw and shape the nail blanks in combination with a moveable side piece, with an
intercepter released by the said side piece, and with bending mechanism such as
described to operate upon the nail head as and for the purposes set forth.
Fourthly. The combination with the bending mechanism of the auxiliary inter-
cepter and intermediate operating devices to stop the passage of the blanks when
the bending mechanism is forced open.
In witness whereof, I, the said William Morgan-Brown, have hereunto set
my hand and seal, this Twenty-ninth day of October, in the year of our Lord
One thousand eight hundred and seventy-eight.
