PROVISIONAL SPECIFICATION.
Improvements in Machinery for Cutting Brads, Shoemakers' Bills
and Blanks for Cut Nails.
I, JOHN MOORE, of 31 Mansfield Street, South Stockton-on-Tees in the County of
Yorkshire, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in machinery for forming brads, shoemakers'
bills, and blanks for cut nails, and consists in an improved form of cutters whereby
I ani enabled to cut two, four, or more at each stroke of the said cutters, and to cut
the articles from a strip or bar of metal having its grain, if any, running longitudinally,
the strip of metal being fed in the direction of the length of the cutters and the
articles being cut from the sides instead of from the end of the said strip. My
invention also consists in suitable guides to be used in conjunction with the said
cutters for guiding the strip of metal to be cut.
My improved cutters are formed and arranged in pairs. One cutter is fixed by
being secured in any suitable manner to a stationary part of the machine, and the
other cutter is fixed to a part of the machine to which an ordinary shearing motion is
imparted so that the cutting edge of the movable cutter has a shearing motion against
the cutting edge of the fixed cutter.
The cutting edge of each cutter takes the form alternately of the outline of the
opposite sides of the articles to be cut, arranged end to end in the direction of the
length of the cutters. The number and arrangement of the said outline forms is such
as to cover the entire width of the strip of metal being cut, so that as the said strip is
fed through the cutters its entire width is utilized and cut up into the articles
required.
Over the fixed cutter is fixed a guide for one side or edge of the strip, the said
guide forming a groove between it and the cutter through which groove the strip of
metal is fed, the outline of the edge of the guide which is over the cutting edge of
the cutter corresponding with that of the said cutter. This guide prevents the strip
of metal from tilting when the moving cutter descends upon it and from lifting when
the movable cutter is raised. The guide for the other side or edge of the strip is
formed on or secured to the under side of the movable cutter.

guides for making brads.
Figure 2 is an end elevation of the same and section of strip being cut.
Figure 2A is a section on line of figure 1.
Figure 3 is a plan of my improved cutters and guides for cutting one form of cut
nail blanks.
Figure 4 is a plan of my improved cutters and guides for cutting shoemakers bills.
a is the moving cutter having a shearing motion, & is the fixed cutter or die, e is
the guide on the fixed cutter, d is the guide on the underside of the movable cutter,
e projects over the longitudinal line of the preceding part of the guided the same
distance as the corresponding part of the cutter, and also forms a stop or shoulder
on the guide d which prevents the strip being pushed too far; f is the strip of metal
being cut.
The operation of my improved cutters is as follows:-The strip of metal fis inserted
between the guides c and d and moved forward the length of one article, the
moving cutter a then descends and the portion a¹ of the said cutter cuts off one
article which leaves on the strip the outline form of one side of a second article. The
moving cutter a now rises and the strip is again advanced the length of another
article. This time the portion a¹ of the cutter a cuts an article off as before and the
portion a² also cuts off the article one side of which was formed by the previous cut.
The cutter a now rises again and the strip is advanced as before, the cutter a again
descends, the portions a¹ and a² act as before, and the portion a³ of the cutter a in
cutting the form of one brad or bill cuts right across the remaining width of the strip
and thus cuts off two brads or bills so that four brads or bills are cut at this and each
succeeding operation.
I have shown cutters for cutting one form of nail blanks but by modifying the
form of my improved cutters they can be used for cutting blanks for cut horse-shoe
nails or any other description of cut nails.
In figure 3 the cutter a has an additional portion a* required to cut off the last
nail blank.
The strip of metal ƒ can be cut all away as shown in the drawing or a wider strip
may be used than the range of the cutters will cover, the articles being cut from one
side or edge and the strip being merely reduced in width.
A double set of cutters or dies b may be used with a moving cutter a acting between
the said cutters b, the cutter a having a cutting edge on both sides forming a punch,
or the punch a can be fixed and motion imparted to the cutters b.
Any even number from two upwards can be cut at one stroke by multiplying the
cutters a and b and using a strip of a suitable width and arranging every additional
pair in advance of, or projecting over, the longitudinal line of the preceding pair by
the distance of the width of two articles placed heads to points as shown in the
relative positions of a² to a³.
The feeding of the strip of metal may be done either by hand or by any suitable
method.

page_text: Improvements in Machinery for Cutting Brads, Shoemakers' Bills
and Blanks for Cut Nails.
I, JOHN MOORE of 31 Mansfield Street, South Stockton-on-Tees, in the County of
Yorkshire, Engineer, 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, reference being had to the accompanying drawing
forming a part of this specification :-
My invention relates to improvements in machinery for forming brads, shoemakers'
bills, and blanks for cut nails, and consists in an improved form of cutters whereby
I am enabled to cut two, four or more of the said articles at each stroke of the said
cutters, and to cut the articles from a strip or bar of metal having its grain, if any,
running longitudinally, the strip of metal being fed in the direction of the length of
the cutters and the articles being cut from the sides instead of from the end of the said
strip My invention also consists in suitable guides to be used in conjunction with
the said cutters, for guiding the strip of metal to be cut.
My improved cutters are formed and arranged in pairs. One cutter is fixed by
being secured in any suitable manner to a stationary part of the machine, and the
other cutter is secured to a part of the machine to which an ordinary shearing motion
is imparted, so that the cutting edge of the movable cutter has a shearing motion
against the cutting edge of the fixed cutter.
The cutting edge of each cutter takes the form alternately, of the outline of the
opposite sides of the articles to be cut, arranged end to end in the direction of the
length of the cutters. The number and arrangement of the said outline forms may
be such as to cover the entire width of the strip of metal being cut, so that as the said
strip is fed through the cutters its entire width its utilized and cut up into the articles
required.
Or the moving cutter may have a projecting cutting edge of the form of the outline
of the head and one side of a single brad or other article, the fixed cutter or die being
formed to receive the said moving cutter. The strip of metal in this case is of the
width of the head of a single brad or other article, the edges of the said strip forming
one side of the brads or other articles cut therefrom, so that at each descent of the
moving cutter two brads or other articles are cut from the said strip.
Over the fixed cutter is fixed, on the stationary part of the machine, a guide for
one side or edge of the strip, the said guide forming a groove between it and the
cutter, through which groove the strip of metal is fed. The outline of the edge of
the said guide which is over the cutting edge of the cutter corresponds with that of

page_text: the said cutter. This guide prevents the strip of metal from tilting when the moving
cutter descends upon it, and from lifting when the movable cutter is raised. The
guide for the other side or edge of the strip is formed on, or secured to, the underside
of the movable cutter.
In order that my invention and the manner in which the same is to be performed
may be clearly understood I will now proceed to particularly describe the same with
reference to the accompanying drawing in which like parts are indicated by like
letters of reference.
Figure 1, of the said drawing, is a plan of my improved cutters and guides for
making brads, cutting four brads at each stroke of the moving cutter.
Figure 2 is an end elevation of the same and section of the strip of metal
being cut.
Figure 3 is a section on line aa of figure 1.
Figure 4 is a plan of my improved cutters and guides for cutting one form of cut
nail blanks, cutting four nail blanks at each stroke of the moving cutter.
Figure 5 is a plan of my improved cutters and guides for cutting shoemakers' bills,
also cutting four at one time.
Figures 6 and
a time.
are plans of my improved cutters for brads, cutting two brads at
A is the moving cutter which is fixed to a part of the machine to which a shearing
motion is imparted, a like motion being thus imparted to the said cutter. B is the
fixed cutter or die which is secured in any suitable manner to a stationary part of
the machine, in such a position that the cutting edge a¹ a² a³ of the moving cutter
has a shearing motion against the cutting edge of the said fixed cutier.
Referring to figure 1 which shows a pair of cutters for forming brads, it will be
seen that the portions a¹ of the cutting edges of the moving and fixed cutters
respectively, take the form of the outline of the head, the tapering side or edge, and
point of the brad. The head of the brad on the cutter a¹ is in the opposite direction
to that on the cutter and each cutter is formed with a recess a* 6* to receive the
form of the head of the brad on the other cutter. The said cutters thus represent
two brads, the point of each of which is against the lip of the head of the other brad.
The portion a³ of the cutter A is formed with a straight edge projecting in line with
the back or straight edge of the brad-form on the cutter and the portion 2 of the
cutter B is formed to correspond with the said portion a². The portions a³ ³ of the
moving and fixed cutters A and B are formed in like manner to the portions a¹¹ but
the form of the brad on the portion a³ projects beyond the line of the cutter a².
Thus the profiles or outlines of the cutting edges of the cutters A and B are such as to
permit of the cutting edge of the moving cutter A. having a shearing action against
the edge of the fixed cutter or die Bas the said cutter A descends, the outline of the
cutter A fitting within that of the cutter B as shown in the drawing, when the cutters
are on the same horizontal plane.
Over the fixed cutter B, is secured on the stationary part of the machine a guide c
the said guide forming a groove c' between it and the said cutter, through which
groove the strip of metal is fed to be cut. The outline of the edge of the said
guide which is over the cutting edge of the cutter B corresponds with the outline of
the portions 616263 of the said cutter. This guide c as previously mentioned, prevents
the strip of metal from tilting when the moving cutter comes down upon it and from
lifting when the moving cutter is raised. The guide d for the other side or edge of
the strip of metal is formed on or secured to the underside of the moving cutter A.
This guide takes the form shown by the dotted line d d in plan figure 1, an abutment
or shoulder e extending in line with the edge of the cutter a² being formed by the
projecting portion d' of the said guide. The said shoulder e prevents the strip of
metal from being pushed too for, and the edge of the projecting portion d' of the
guide serves as a guide to the strip when reduced in width by the cutters a¹ a².
The operation of my improved cutters is as follows: The strip of metal is inserted
between the guides c and d and moved forward the length of one brad, that is to say to

page_text: the farther end of the recess a* in the portion a¹ of the cutter A. The moving cutter A
then descends and the portion a' of the said cutter cuts off one brad (the edge of the
strip forming the straight edge of the brad) which leaves on the strip the outline
form of one side of a second brad. The moving cutter A now rises and the strip is
again advanced the length of another brad, that is to say, to the shoulder e. This
time the portion a' of the cutter A cuts a brad off as before and the portion a² also
cuts off the brad, one side of which was formed by the previous cut. The cutter A
now rises again and the strip is advanced as before, so that its reduced portion comes
to the farther end of the cutters a³ 63, the cutter A again descends, the portions a¹
and a act as before, and the portion a³ of the cutter A in cutting the form of one
brad cuts right across the remaining width of the strip and thus cuts off two brads so
that four brads are cut at this and each succeeding operation.
In figure 4 I have shown cutters for cutting one form of nail blanks, and in figure 5
I have shown cutters for cutting shoemakers' bills. In both cases the said cutters are
of similar construction and arrangement to those above described for cutting brads,
varying only in the outline of the cutters to adapt them to cut the articles desired,
and with the exception that in the cutters for cutting nail blanks shown in figure 4,
the moving cutter A is provided with an additional cutting portion a to cut off
the last nail blank. In both cases the action of the said cutters is precisely similar to
those shown in figures 1, 2 and 3.
I have shown cutters for cutting one form of nail blanks only, but the form of my
improved cutters may be varied so that they can be employed for cutting blanks for
cut horse-shoe nails. or any other description of cut nails.
In figures 6 and 7 I have shown cutters for forming brads and cutting two brads
at each stroke of the cutter A¹. In figure 6 the cutter A¹ has a projecting cutting
edge of the form of the outline of the head, tapering side and point of a single brad,
the edge of the fixed cutter or die B¹ being formed to correspond. In this case the
strip of metal is of the width of the head of one brad only and its edges form
the straight sides of the brads cut therefrom. The said strip is fed forward in
the direction of the length of the cutters so that its end projects beyond the point
of the cutter A¹ to the extent of the depth of the lip of a brad. The cutter A' then
descends and in cutting one brad out of the strip leaves another brad lying upon the
fixed cutter B. The strip is then advanced to the same extent as before and thus
pushes the brad off the fixed cutter B; the moving cutter A again descends and the
operations are repeated, two brads being cut at each stroke of the cutter A¹. In
figure 7 the cutters A B are of similar construction but the form of the outline of
the cutting edge of cutter A¹ is reversed, the head of the brad being in the opposite
direction. In this case the strip of metal being fed to the cutters, by the first stroke
of the cutter A a single brad only is cut off, leaving the form of another brad on the
strip. The strip is then fed into the position shown in the drawing, the cutter A¹
descends and at this and each succeeding stroke cuts two brads, one out of the side of
the strip and the other from the end of the strip, which was formed by the
previous cut.
The form of the cutting edges of the cutters A B shown in figures 6 and 7 may
be varied so as to adapt them for cutting nail blanks of various forins or shoemakers'
bills.
The cutters shown in figures 4, 5, 6 and 7 may be provided with the guides c and d
as above described.
The strip of metal can be cut all away as shown in the drawing or a wider strip
may be used than the range of the cutters will cover, the articles being cut from one
side or edge and the strip being merely reduced in width.
Any even number of brads, nail blanks or bills from two upwards can be cut at one
stroke by increasing the length of the cutters A and B and the number of outline
forms thereon using a strip of metal of a suitable width and constructing the cutting
edges of the said cutters so that every additional pair of outline forms, formed on the
said cutters is in advance of or projects over the longitudinal line of the preceding

page_text: pair by the distance of the width of two of the articles they are formed to cut, placed
heads to points, as shown in the relative positions of a² to a³.
The feeding of the strip of metal may be done either by hand or by any suitable
means.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is:-
FirstCutters for cutting brads, shoemakers' bills and blanks for cut nails,
constructed and arranged substantially as herein set forth and illustrated in the
accompanying drawing.
Second The combination with the said cutters of the guides c and d substantially
as shown and described.
