Improvements in Machines for the Manufacture of Horse-shoe and
other Nails.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Pateni Agonts,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature of
this invention to be as follows:-
This invention relates to machines for the manufacture of horse-shoe and other
nails.
In the machine which forms the subject of the present invention the blanks of the
nails, after having undergone the preliminary cutting and stamping operations, are
inserted into notches in a ring revolving upon a stationary plate and provided with
ratchet teeth at its outer edge. This ring receives at certain intervals a partial
circular motion, from a lower shaft, through the medium of an excentric and lever
and pawl arrangement so that each time it moves a sufficient distance for a fresh
blank to be exposed to the action of the various devices from which it is to receive
its final shape. The said lower shaft is driven from the main shaft by means of spur
wheels.
As soon as a blank is brought under the flattening die it is seized by a pair of
jaws or tongs connected with a pivoted lever and operated from the main shaft by a
cam; these jaws being caused to open precisely at the moment when the blank is
moved up to tliem, by another cam, whereupon they immediately close under the action
of the same cam. In being thus seized by the jaws the blank is at the same time
lifted in position to be locked between lateral and longitudinal cheeks. The first two
cheeks are stationary while the two others are fitted in movable carriages and are so
shifted in relation to either of the first two cheeks by the joint action of a cam and
lever on one hand, and that of the projecting portion of another cam aud lever on the
other hand that the blank as it is raised in position is locked in, between them and the
corresponding fixed cheeks.
The die which is moved by a conveniently arranged carriage towards the blank is
operated by a lever through the medium of a slide which holds the edge of a heart
cam engaged between running sheaves and is thereby caused to advance or recede the
required distance.
The movable cheeks recede at the same time as the die moves back to its original
position, so that the blank with its head stamped into shape is released and being once
more grasped by the jaws is reinserted into the catching again by which it is
carried forward a sufficient distance to enable it to take up its position between a
fixed side cheek and a small roller where it is stretched or drawn out towards its
point. For this purpose the said cheek which is fitted in one arm of a pivoted lever
is cause to advance towards the blank under the influence of a cam while on the
other hand a rod which carries the aforesaid small roller, is drawn downward by an
excentric so that the small roller which is mounted beside a second roller is carried
along an incline on the frame of the machine. The consequence is that the first
roller as it descends on the incline presses against the blank with a gradually
increasing force and thereby draws the same into shape towards its point.
When the pair of rollers have reached the end of the incline, they are made to
roll up again while at the same time the lever arm carrying the side cheek swings
back, together with the said cheek, thus once more releasing the blank. This is then
;

the proper intervals by a cam mounted on the main shaft and acting upon runners, and thus
alternately approaches, or recedes from, the blank. In this carriage are arranged both the
intermediate die and the cutter, at a distance corresponding to the intervals between
the notches in ring; so that the said die is enabled to sharpen one side of the point
of the blank; and slightly to bend the same, while at the same time the cutters cuis
into shape both sides of the blank, which has just undergone the action of intermediate
die, and finally provides it with a sharp point. The nail thus completed is, by a
further partial turning of the ring caused to meet a bracket fixed in an inclined
position in the stationary plate whereby it is expelled laterally from the notches
and drops out of the machine through a slot provided for the purpose in said
plate.

1, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
My invention relates to machines for the manufacture of horse-shoe and other nails
and it consists in the construction and arrangement of mechanism for successively
effecting the forming of the head, the stretching or rolling out and finally the
pointing and clipping of the shank.of the previously cut or punched nail-blanks.
In the accompanying drawings,
Figure 1 is a vertical longitudinal section of the entire machine.
Figure 2 is a vertical cross section thereof.
Figure 3 is a top view of the entire machine partly in horizontal section.
Figure 4 is a vertical section of a part of the machine showing the device for
stretching or rolling out the shaft of the nail blank and
Figures 5, 6 and 7 show the dies and knives in connection with the actuating
parts for effecting the pointing, shaping and clipping of the shank of the nail-
blanks.
Similar letters refer to similar parts throughout the several views.
The nail-blanks after having undergone the preliminary cutting or punching
operations, are inserted into notches a in a ring a revolving upon the annular
projection a¹ of the stationary bed-plate A and provided with ratchet teeth at its
outer edge. This ring a receives at certain intervals a partial circular motion, from a
lower shaft w, through the medium of an eccentric, rod 3, lever bb and pawl
arrangement b so that each time it moves a sufficient distance for a fresh blank to be
exposed to the action of the various devices from which it is to receive its final shape.
The said lower shaft to' is driven from the main shaft w by means of the spur
wheels c c¹.
As soon as a blank is brought in line with the forming die it is seized by a pair
of jaws or tongues connected with a pivoted lever and operated from the
main shaft w by a cam fand spring f these jaws being caused to open precisely
at the moment when the blank is moved up to them, by another cam f, acting
upon the arm of the tongue whereupon they immediately close under the action
of a spring (Figure 1).
In being thus seized by the jaws the blank is at the same time lified in position

to be locked between lateral and longitudinal jaws or cheeks d d¹ d² d³.
two checks d d' are stationary while the two others d d³ are fitted in movable
carriages d d and are so shifted in relation to either of the first two cheeks by the
joint action of a cami d and lever (Figure 1) on one hand, and that of the circum-
ferential projecting portion d' of the above mentioned cam operating the tongue f
and a lever (Figure 2) on the other hand, that the blank, as it is raised, in
position, is locked in, between them and the corresponding fixed cheeks d d¹.
The die. which is moved by a conveniently arranged carriage g towards the blank,
is operated by a lever g g through the medium of a slide which holds the edge g
of a heart cam g engaged between running sheaves and is thereby caused to
advance or recede the required distance.
The movable cheeks dd recede at the same time as the dio g moves back to its
original position, so that the blank with its head stamped into shape is released and
being once more grasped by the jaws is reinserted into the catch ring a, by which
it is carried forward a sufficient distance to enable it to take up its position between
a side cheekh and a small roller where the nail shaft is stretched or rolled out
towards its point to the length desired. For this purpose the said cheek h, which
is fitted in one arm i of a pivoted lever is caused to advance towards the blank,
under the influence of a cam mounted on the shaft we', while on the other hand a
rod which carries the aforesaid small roller is drawn downward by an eccentric k
(Figure 4) on the same shaft, so that the small roller which is mounted beside the
said roller at the end of the rod is carried along an incline on the frame of the
machine. The consequence is that the roller has it descends presses against the shaft
of the nail with a gradually increasing force and thereby stretches the same to the
length desired and into shape towards its point.
When the pair of rollers h h have reached the end of the incline 1, they are made
to roll up again, while at the same time the lever arm carrying the side check h
swings back together with the said cheek and under the action of a spring thus
releasing the blank. This is then further carried on by the ring a towards a carriage m
which is moved backwards and forwards at the proper intervals by a cam 7 mounted
on the main shaft and acting upon runners m¹ m², and thus alternately approaches,
or recedes from the blank.
In this carriage m are arranged both the intermediate die n and the cutters o p
at a distance corresponding to the intervals between the notches a in the ring a; so
that the said die n is enabled to sharpen one side of the point of the blank, and slightly
to bind the same, while at the same time the cutters op clip away the waste and cut
into shape both sides of the blank, which has just before undergone the action of the
intermediate die n, and finally provides it with a sharp point. The nail thus completed
is, by a further partial turning of the ring a caused to meet a bracket fixed in an
inclined position in the stationary plate a whereby it is expelled laterally from the
notches a and drops out of the machine through a slots provided for the purpose in
said plate a!.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is:-
First. In a machine for the manufacture of horse-shoe and other nails, the com-
bination of the revolving ring a, the cheeks d d d² d³ the jaws f for seizing and
lifting the nail blank between said cheeks and the die g for jumping the head on the
nail, substantially as hereinbefore described.
Second. In a machine for the manufacture of horse-shoe and other nails the com-
bination of the ring a having notches a² and revolving upon a stationary plate or
frame a with the cheeks dd' d' d², the jaws f for lifting the nail-blank between said
cheeks, the stamping die y, the cheek , the rod k carrying rollers
