I, WILLIAM Morgan-Brown, of the Firm of Brandon and Morgan-
Brown, Engineers and Patent Agents, of 38, Southampton Buildings,

FILT
This Invention has for its object improvements in machinery for the
› manufacture of horse-shoo nails.

page_text: In that process in the manufacture of horse-shoe nails in which the
blank passes down vertically between two pairs of rolls head down, the
upper pair of rolls first acting upon the shank, and the blank then
dropping through a conductor to the lower rolls, which in turn pass
upon the shank, some trouble is experienced from the fact that a blank 5
is sometimes obstructed in its passage through the conductor which
leads from the upper to the lower pair of rolls, the upper rolls continuing
to feed blanks down into the obstructed conductor until the walls of the
conductor break away or the machine is otherwise broken or injured.
The purpose of this Invention is to obviate such difficulty and the desired 1
result is accomplished as follows:-The two opposite side walls of the
conductor are formed flaring toward the front, and the front wall is
made as a gate secured by a latch, which latch holds the door closed so
long as the blanks pass by it one by one in regular succession; but
when the blanks collect in the conductor by reason of one becoming 1
detained from any cause so that the others cannot pass it, the pressure
of the other blanks tends to cause the blank to move outward toward the
gate, pressing against which they force it open.
By means of a connection between the opening door and some point
above the upper rolls, a stop is made to intercept the further delivery of 2
the blanks to the upper rolls, and thus all injury to the machine is
averted.
The Invention consists in forming the hopper or conductor with the
gate to be opened by the outward pressure of the nail blanks, and in
combining with this gate an interceptor which is thrown into position by au
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Morgan-Brown in the Great Seal Patent
Office on the 11th February 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM 30
MORGAN-BROWN, of the Firm of Brandon and Morgan-Brown, Engineers
and Patent Agents, of 38, Southampton Buildings, London, and 13,
Rue Gaillon, Paris, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of August in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said William Morgan-Brown, Her special
license that I, the said William Morgan-Brown, my executors, adminis-
trators, and assigns, or such others as I, the said William Morgan-
Brown, 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
"IMPROVEMENTS IN MACHINERY FOR THE MANUFACTURE OF HORSE-SHOE NAILS," "
communication to me from abroad by Thomas House Fuller, of Boston,
Massachusetts, United States of America, upon the condition (amongst
others) that I, the said William Morgan-Brown, my executors or
administrators, by an instrument in writing under my, or their, or one
of their hands and seals, should particularly describe and ascertain the
naturo of the said Invention, and in what manner the saine was to be
performed, and cause the same to be filed in the Great Scal Patent
Office within six calendar months next and immediately after the date of
the said Letters Patent.
NOW KNOW YE, that I, the said William Morgan-Brown, 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 following statement thereof, that is to say:--
In that process in the manufacture of horse-shoe nails in which the
blank passes down vertically between two pairs of rolls head down, the
upper pair of rolls first acting upon the shank and the blank then
dropping through a conductor to the lower rolls which in turn pass upon
the shank, some trouble is experienced from the fact that a blank is
sometimes obstructed in its passage through the conductor which leads
from the upper to the lower pair of rolls, the upper rolls continuing to
feed blanks down into the obstructed conductor until the walls of the
conductor break away or the machine is otherwise broken or injured.
The purpose of this Invention is to obviate such difficulty, and the
desired result is accomplished as follows:-The two opposite side walls
of the conductor are formed flaring toward the front, and the front wall

page_text: is made as a gate secured by a latch, which latch holds the door closed.
so long as the blanks pass by it one by one in regular succession; but
when the blanks collect in the conductor by reason of one becoming
detained from any cause so that the others cannot pass it the pressure of
the other blanks tends to cause the blank to move outward toward the 5
gate pressing against which they force it
open.
By means of a connection between the opening door and some point
above the upper rolls a stop is made to intercept the further delivery of
the blanks to the upper rolls and thus all injury to the machine is
averted.
The Invention consists in forming the hopper or conductor with the
gate to be opened by the outward pressure of the nail blanks, and in
combining with this gate an interceptor which is thrown into position by
the opening gate to stop further supply of blanks to the rolls. The
Drawing represents a hopper or conductor embodying the Invention.
A shews the conductor in front elevation; B is a plan of it; C is a
side view of it; D is a front view of it, the gate being open.
.
1
a, b, denote the two upper rolls to the action of which the blank is
first presented dropping through a guide tube c for said rolls to seize its
head and pass upon its shank. As the head of the nail blank passes 2
from these rolls it enters the conductor e, by which conductor it is
guided and directed to the action of the lower rolls f.g. 'This.con-
ductor e is a thick solid plate of metal fitting between the four rolls äs
seen at, 4, and having extending through it a vertical passage h, the
dimension of which is such at all points throughout its length that the 2
head of the blank cannot turn-around laterally, but-must-drop-through-
the conductor in the same position that it enters or is presented to the.
same, by which means the blank although moving with perfect freedom
must be properly presented in position for the lower rolls to scize it, the
passage gradually contracting so that at its lower end its size is but a
.slightly greater than the size of the nail head. The side and rear walls.
of the passage are formed by the solid plate, but its front wall is formed
by the gate. This gate swings-on-hinges-k, and is held firmly in closed
position by a spring latch that enters a notch min a pin n extending
from the plate e. The side walls o of the nail passage flare from the a
rear wall to the gate as seen at B. When a blank enters the passage it
drops down through to the rolls below, but if said rolls fail to take it, or
…
.
•

page_text: if from any other cause it is stopped in the nail passage the next blank
that comes down is forced into the passage, and becoming jammed in
with the other, neither will be taken by the lower rolls; but as others
follow the flaring sides of the passage cause them or the previous blanks
to press outward against the gate so that the latter is forced open, and
the nails discharged through the front of the opened passage, thus
relieving the conductor plate without injury to it or to any other part of
the machine. At the top of the gate is a projection p into a slot in
which enters a wire q extending from a hook ", the point of which
stands in front of an opening in the nail tube abovo the upper rolls.
The hook is pivoted on a pin s, and is held back by the shut gate; but
whenever the gate is forced open the hook is released, and its point
thrown forward by the stress of a spring t, the point of the hook then
entering the nail tube in front of it, and intercepting further descent
of the blanks.
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,-
1. The nail guiding plate formed with the flaring sides o, and having
the gate i arranged to bo opened by the forward pressure of accumulating
blanks, substantially as shewn and described.
2. In combination with the gate the hook or interceptor operating
substantially as shewn and described.
In witness whereof, I, the said William Morgan-Brown, have
hereunto set my hand and seal, this Eleventh day of February,
in the year of our Lord One thousand eight hundred and seventy-
three.
WILLIAM MORGAN-BROWN. (L.S.)
