I, ALEXANDER HENRY REED, of Suffolk House, Laurence Pountney Hill, Cannon
Street, in the County of Middlesex, 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 :-
This invention relates to devices for fastening together sheets of paper, and it has
for its object to provide a novel paper fastener wherein diverging cutters serve to
sever the paper as the fastener is passed through the same.
The invention consists in the construction of paper fasteners hereinafter described
and claimed, reference being made to the accompanying drawing in which
Fig. 1 is a metal blank for the improved fastener.
Fig. 2 is an isometric view.
Fig. 3 is a front view of a fastener made from a blank of the form represented in
fig. L
Figs. 4, 5, and 6 show inodifications of the fastener.
Similar letters indicate corresponding paris.
The blank figure 1 is cut out from a sheet of metal to the required shape and is then
bent up in a suitable machine to the shape or condition shown in the other figures. The
central portion or hody A of the fastener blank is made of equal width as shown in the
Irawing, but it may be of unequal width, when it is desired to make the head of the
astener wider than the shanks or to vary the proportions of the body of the fastener
rom any cause. The ends of the blank are cut in such a manner as to produce at
ach end but on opposite sides a sharp extremity B B, the cut being either on a curved
onvex line, as shown in figures 1, 2, and 3, or on a straight line as in figures 4 and 6
r on a concave curve as at figure 5. In each case the points or extremities of the
wo shanks are to be on opposite edges, so that when the fastener is applied to sheets
f paper, the extremities B B of the two shanks will perforate the paper, and then as
he shanks are pushed further along the paper which is between the perforations will

construction facilitates the application of the fastener to the paper or to a body of
several sheets of paper, the resistance to the entrance of the fastener being more
easily overcome than when the points of the shank are central to the width of the
shanks.
In constructing the paper fastener, sufficient portions of the ends of the blank are
measured off to form the two shanks measuring equal lengths from the extremities B B
leaving enough in the intermediate part of the body A to form the head, which is
formed by bending the parts E E of the body over on the central part D of the blank
in such a manner as to bring the shanks FF against each other, and so as to make the
shanks project at right angles to the parts E. The parts D, E, E, form the head of
the fastener.
The forms here shown in respect to the forms of the ends of the shanks, or the
shape or extent of their cutting edges, are not claimed, as such ends and edges may be
made of various forms.
By constructing the fastener as above described the perforating points B B of the
shanks are on opposite sides of the middle or central line of the shanks, and con-
sequently each shank can be operated with ease and be readily seized by the fingers of
the operator and bent down after the shanks have been pushed through the paper.
This construction enables one to separate the shanks more readily than when the ends
of the shanks overlie each other as in the ordinary construction, because the prongs of
the shanks project from opposite edges of the shanks and the prongs do not overlie
each other. This arrangement of the prongs produces along and between their inner
edges from their inner ends to the point where they cross each other angular cutting
edges which will make a drawing cut as the points are pushed through the papers to
be fastened.
The points B can be made more or less sharp or can be made a little blunt it
desired.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, I declare that what I claim is :
1. A paper fastener comprising two parallel shanks resting against each other and
having the inner adjacent edges of their pointed extremities formed into divergin
cutters CC substantially as and for the purpose described.
2. As an improved article of manufacture a paper fastener consisting of a strip
metal having the folded head D E and the pointed folded shanks Flying parallel an
against each other, with their inner adjacent edges, at their pointed extremitie
formed into diverging cutters, CC; substantially as and for the purpose described.
