the Manufacture of Animal Shoe Nails.
:
I, GEORGE MACAULAY-CRUIKSHANK of 135 Buchanan Street Glasgow in the
County of Lanark, Consulting Engineer, Fellow of the Institute of Patent Agents,
do hereby declare the nature of this invention, a communication to me from abroad
by Johan Oliver Johansson Kollén and August Bernhard Johansson Kollén of
Rådanefors, Frendefors, Sweden Engineers, to be as follows :——
1
This invention relates to improvements in apparatus for cutting or punching out
from a length of plate or rod blanks to be used in the manufacture of horse and
other animal shoe nails.
}
The invention relates to the feeding parts of such apparatus which as improved
consist of a reciprocating table actuated by a lever one end of which passes through
a slot in the table whilst its other end carries a roller actód on by a cam or eccentric
on the end of the shaft carrying the ordinary punch operating mechanism.
The feeding table carries in upwardly projecting brackets a grasper whose under
side is suitably formed to grip the upper surface of the nail plate the grasper being
centred at its rear end on a pin in the said brackets. The grasper is caused to take
hold of and release the nail plate at the proper times by a cam shaped lever centred
in links carried in brackets on the framing or fixed table of the machine. The cam
shaped lever is also connected by a link to an arın projecting from the reciprocating
punch block by which connection when the punch descends and grips the nail
plate the pressure on the grasper is released and it with the reciprocating table is
enabled to move backwards to take a fresh hold on the nail plate and feed it
forward when the punch again ascends.
The reciprocation of the table is regulated by stops or in other ordinary manner.
Between the cam lever and the grasper a spring is preferably placed to cushion
the pressure; and to diminish friction a roller is placed between the adjacent
surfaces of the lever and spring. To regulate the downward pressure of the cam
lever itself the pin on which it is centred is made with an eccentric enlargement
the cum being on the said enlargement.
A lever or handle is placed on the end of the pin and a series of holes is made
radially in the side of one link. By passing a pin through the said lever handlo
into one or other of the holes the adjustment of the cam lever is maintained.
Dated this Twenty-third day of December 1885.

the Manufacture of Animal Shoe Nails.
I, GEORGE MACAULAY-ĊRUIKSHANK of 62 Saint Vincent Street Glasgow, in the
County of Lanark, Consulting Engineer, Fellow of the Institute of Patent Agents,
do hereby declare the nature of this invention (a communication to me from abroad
by Johan Oliver Johansson Kollén and August Bernhard Johansson Kollén of
Rådanefors Frendefors, Sweden, Engineer, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:
This invention relates to improvements in apparatus for cutting or punching out
from a length of plate or rod blanks to be used in the manufacture of horse and
other animal shoe nails.
The invention is illustrated by the several figures on the accompanying
drawings, figure 1, being a side elevation; figure 2 an elevation at the end
marked X figure 1; figure 3, a cross section on the line a-a figure 1; figure 4,
a detailed view of certain of the parts drawn to an enlarged scale and figure 5, an
elevation at the end marked Y figure 4 and as shown by these figures the invention
relates to the feeding parts of such apparatus which as improved consist of the
usual reciprocating table b, actuated by a lever c, one end of which passes through
a slot in the table whilst its other end carries a roller d, acted on by a cam or
eccentric e, on the end of the shaft f, carrying the ordinary punch operating
mechanism.
The feeding table b, carries, in upwardly projecting brackets g, formed on or
secured thereto a grasper h, whose under side is serrated at the forward part to
grip the upper surface of the nail plate i, the grasper being contred at its rear end
on a pin in the said brackets 9. The grasper h, is caused to take hold of and
release the nail plate at the proper times by a cam shaped lever j, centred in
links k, carried in brackets l, formed on or secured to the framing or fixed table m,
of the machine. The cam shaped lever j, is also connected by a link or links n, to
an arm o, projecting from the reciprocating punch block p, by which connection
when the punch descends and grips the nail plate the pressure on the grasper is
released and it, with the reciprocating table b, is enabled to move backwards to
take a fresh hold on the nail plate and feed it forward when the punch again
ascends.
The reciprocation of the table is regulated by stops r, or in other ordinary
manner.
Between the cam lever j, and the grasper h, a spring 8, is preferably placed to
cushion the pressure; and to diminish friction a roller is or may be situated
between the adjacent surfaces of the lever and spring as indicated at t. To
regulate the downward pressure of the cam lever itself the pin u, on which it is
centred is made with an eccentric enlargement, as indicated in dotted lines at q,
figure 1, the cam being on the said enlargement.
A lever or handle v, is placed on the end of the pin u, and a series of holes พ, is .
made radially in the side of one link k. By passing pin through the handle v
a

page_text: into one or other of the holes w, the adjustment of the cam lever j is maintained to
give the pressure desired.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to
me I declare that what I claim is :-
1. In apparatus for cutting or punching blanks for animal shoe nails, feeding
mechanism arranged and combined substantially as herein before described with
reference to the drawings annexed.
2. In feeding mechanism for the class of machines referred to the combination
of the grasper h, and lever j, substantially as described with reference to the
appended drawings.
