COMPLETE SPECIFICATION filed by the said Raphael Hunter Brandon at
the Office of the Commissioners of Patents on the 24th October 1883.
Raphael Hunter BRANDON of N° 1 rue Laffitte, Paris, France Engineer and
Patent Agent IMPROVEMENTS IN MACHINES FOR MANUFACTURING BLANKS FOR
HORSE SHOE NAILS communicated to me by Frederick Myers, a citizen of the
United States of America
This invention has for its object the production of an organized machino for
presenting a plate of metal of suitable shape for the production of horse shoo nail
blanks to the action of dies which cut the said plate transversely and form blanks,
after which a header spreads and thickens the head of the blank. This invention
consists essentially in a machine for the production of horse shoe nail blanks, the
same including dies to cut and form said blanks from a metal plate, and a header
to spread and thicken the heads of the blanks, when the same are combined with
mechanism substantially as herein described to enable the said metal plate to bo
held and turned to correctly present its end to the action of the said dies and
header as will be described referring to the accompanying drawings. The present
invention also includes means for holding the nail plates and for turning the same
and feeding it forward at the proper times. Figure 1, is a plan view of a machine
containing my improvements. Figure 2 is a side elevation of the same. Figure 3
is a front elevation of the same. Figure 4 is a detail of mechanism and dies.
Figure 5 is a detail of mechanism and dies. Figures 6, 7, 8, 9, 10 and 11 are
details of dies to be referred to. Figure 12 is a horizontal section of the revolving
tube and nippers to control the said nail plate and feed it to the cutting dies.
Figure 13, is a detail of the carriage to support the rear end of the revolving tube.
Figure 14, is a sectional detail on line 2 of the tube and clamping mechanism to
move the feed rod. Figure 15, a cross section on line figure 12, of the revolving
tube and its cam-projection to raise the front end of the said tube as it is partially
•

page_text: rotated. Figure 16, shows tho delivering end of the tube 7. Figure 17, is a
sectional detail on the line xx fig: 1; and Figure 18 is a detached detail of the
holder w; its die x, and the stop g' and spring 10 to act against opposite sides of
the nail plate. The frame work a has plumber-blocks b to carry the shaft c
which is rotated by power. This shaft has cams d, e and f, and a disk g, having
a cam projection on the face of it. The cam d operates the lever i, connected
with the rock shaft k the latter having a second arm l, shown clearly in figs: 3, 4
& 5. Secured in the arm in any ordinary way, are the dies m & guido n.
The die has its upper end shaped to conform to the form it is desired to give to
the under side to the head of the blank, while the guide n is adjusted to the
required position to form a guide for the reciprocating header c¹.
At
These dies constitute the movable anvil. The came operates the lover o
connected with the rock shaft p, having projecting therefrom a bed for carrying
the die q, see figs: 1 & 6. The cam operates lever r connected with the rock
shaft & which is provided with a head t which carries the die u and gage v.
8
the front of the frame work a is placed a holder w which carries the bed dio or
stationary cutter x. The cam of the disk g operates the lever z pivoted at a¹
on a projection of the frame a. The lever operates as the header bar bin which
is secured the header c¹ for heading the blanks. The gage serves as a stop for
the nail plate f¹ by coming against it, as shown in fig: 11, the dotted lines
representing the line on which the die will next cut the said plate. g¹ is a gage
or stop to bring the nail plate into and regulate its position laterally, it being
attached to the rest w and shown only in figs: 1, 11, & 18. The die m is situnted
with regard to the die u and gage v, as shown in fig: 8, so that sufficient room is
left at one side of it for the end of the spring d¹ to intervene between the outer
side of the die m and the inner side of the gage v and as shown in fig.: 7, tho end
of the spring d when not depressed by the descent of the die u upon it comes to
the level of the upper edge of the die x so that when the die u descends upon the
nail plate inserted between the dies and a, the spring is depressed and
holds the blank a fig: 9 severed therefrom in the position it is in immediately
after the act of severing has been accomplished, the die u still descending until it
comes to the position shown in fig: 8, where the die m and guide n forming the
movable anvil (having moved into position immediately below it at the time the
end of the plate was being severed) form gripes for the nail blank a* fig: 9 on its
upper and lower sides, while tho dies and a form gripes at its edges. The die q,
advances to grip the nail blank at its side as the dio u descends to cut off the
blank from the plate, the die u also holding the blank at its top. The die z being
stationary resists the thrust of the die q, & the die m resists the pressure of the
die u. Fig 10 shows clearly a horizontal section of the die. The said die u
consists of two parallel surfaces 1 & 3 and two inclines 2 & 4. These correspond
and exactly agree with similar surfaces on the end of the die x see fig: 9. The dio
extends somewhat farther and has a parallel surface 5, agreeing with the parallel
surfaco 5, formed by the gage in fig: 10. The die 2 is provided with the
surfaces 1, 2, & 3, the surfaces being an incline, and the opposing die has
surfaces 1, 2, & 3, to correspond, see fig: 6. As soon as the dies u & q bear upon
and hold the nail blank between themselves and the dies m & x, a chamber is
formed for holding the blank, which chamber is of the exact size and configuration
it is desired that the body & head of the blank have when compressed, and the
head of the blank is upset by the header c¹ while the blank is guided or held on
its four sides by the guide n & dies u, q, & x. Fig. 8, represents the blank a²
held by the dies u & m, with the guide n & die u guiding the header c¹ which is
in the act of coming forward to upset or shape the end of the blank a. The
configuration of the cams d, e, & f, is such that they retain the dies operated by
them in the position required, holding the blank while the header passes in and
upsets the head in the chamber, the header retiring by the action of the
spring c. The dies q & u also retire, and as the latter rises above the level of the
inner extremity of the die x (the spring d' only rising to the level of the extremity

page_text: of the die x,) the blank is released and falls in front of the movable anvil or die m
which with the guide n has receded a sufficient distance for that purpose. The
levers i, o, &r are each provided with ordinary springs to keep their extremities
pressed down upon the surfaces of their respective cams, and the gage v, guide n &
dies m, u & are each provided with suitable set screws at their backs, whereby
they may be adjusted with great accuracy and maintained in their proper relative
positions. To obviate sticking of the nail blank in the dies zor q, a poker made
as a reciprocating rod operated by the main shaft or otherwise may be added to
the machine. Against the edge of the nail plate f', there acts a spring 10 see
figs: 1 & 18, to keep the opposite edge of the plate pressed against the gage or
stop g' when the blank is cut from the plate. To enable the end of the plate f¹ to
be presented automatically to the dies, I have provided a pair of nippers 2, attached
to a head 3, connected with a rod 5, placed within a small non-rotating but
reciprocating tube 6. The rear end 8, of the rod 5, is entered into a holo in an
axle 10 provided with wheels 12, which rest upon an inclined track 11. The axle-
tree 10 has connected with it a cord 13 which is extended to a drum 14 on which
the cord 13 is wound, when it is desired to draw the rod and nippers backward
out of the tube 7, to apply a new length of nail plate f¹. The drum 14 is on a
shaft having a suitable crank & handle 16. The nippers are closed upon the
plate by a set screw 4. The tube 7 has within it four guides 18, thus dividing
the interior into a cruciform space to receive the nippers, and four channels for
Jugs 19 projecting laterally from the nippers as shown in fig: 15, the edges of tho
nail plate also working in the said grooves. Tho forward end of the tube 7 is
provided with an eccentric 20, seen best in figs: 2 & 15, which rests by gravity
upon a suitable smouth bearing carried by the holder w. Rising from the
holder w is a yoke 21 which embraces the tube 7 and prevents it from being
moved laterally as the front end of the tube rises and falls, as it does at cach semi-
rotation, when turning the nail plate. The rear end of the tube 7 is supported
by a suitable swivelling yoke 22. The plate f, after each blank is cut from it,
must be drawn back for a short distance in order to remove the end of the plato
sufficiently back from the dies to permit the plate to be turned over before cutting
the next blank. To do this, I employ a clamping mechanism composed chiefly of
the blocks 23 pivoted on the bar 21, connected by pin 26 with the slide 25 fitted
into the guide 28, the said slide 25 being connected to rod 27 which at its rear end
has a head 29 provided with a roll 30 which is acted upon by the cam diskf sce
figs: 1 & 2. As the rod 27 is moved in the direction of the arrow fig: 1, the
blocks 23 will clamp the tube 6 and draw it backward, at which time the tubo 7
will be turned for half of a rotation by the belt 32 thereon extended over a pulley
attached to a toothed wheel 33 which is engaged and moved in first one, then in the
opposite direction by the toothed segment 34 projecting from the rock shaft 35,
having an arm 30, provided with a pin 37 which is engaged by the notched part of
a reciprocating rod 38, attached to the crank pin 39, of a gear 40, on shaft 41, the
said gear being engaged by the pinion 42, on shaft c. The tube 6, rod 5, and
plate f, are moved forward and held pressed forward by the weight 43, attached
to the cord 15, the said weight acting to feed the rod and plate f' forward when-
ever the rod 27 is drawn in the direction opposite the arrow on it in figure 1, tho
clamp being then released from tube 6. The weight 43, acts to project the end
of the nail plate against the stop v. I do not make claim broadly to the dies to
cut the blanks from the nail plate and head the same, but only to dies and a
header having cooperating with them means by which to hold and turn the metal
plate and permit it to be fed forward at the proper period.

page_text: 2. A machine to cut nail blanks from a plate, it containing the dies to cut out
the blank, the gago v, dies m, and 7, and guide n to encloso the blank at its sides
and edges, and the header to upset the head of the blank while held as described,
and a nail plate feeding mechanism to present the nail plate to the dies, substantially
as and for the purpose described.
3. Mechanisin substantially as described for holding the nail plate and turning
the same and feeding it forward at the proper times, substantially as set forth.
In Witness whereof, I the said Raphael Hunter Brandon, have hereunto set
my hand and seal this 20th day of October in the year of our Lord 1883.
