Certain Improvements in C-spring Clips for Holding Papers and
for other like Uses.
We, MAURICE MYERS, of Charlotte Street, Birmingham, Warwickshire, Pen
Manufacturer, and JAMES LOWE, of Highfield Road, Saltley, Warwickshire, Works
Manager, do hereby declare the nature of this invention to be as follows:-
This invention has reference to those C-spring clips, for holding papers and for other
like uses, in which two clipping levers of sheet metal making an acute angle with each
other are, near their wider or meeting ends, directly acted upon and pressed together
by the extremities of a sheet steel spring which is C-shaped in cross-section. Two
narrow holes are pierced a short distance apart near the centre of the C-spring through
which the narrow or outer ends of the levers pass, that part of the C-spring which is
between the levers forming their fulcrum. The C-spring is in contact with the wider
part of the levers and thus prevented from moving nearer to their meeting ends but
the act of opening the clip by pressing together the outer ends of the two levers has a
tendency to displace the C-spring by causing it to move along the levers towards their
outer ends which defect it is the chief object of this invention to overcome.
According to this invention we form a projecting rib along each lever parallel with
and immediately within the extremities or jaws of the C-spring and between the said
jaws and the fulcrum of the levers. As when the clip is in use the extremities of the
C-spring cannot spring over these projecting ribs the C-spring is prevented from
moving out of position towards the outer or free ends of the levers.
We prefer to use on each lever a single rib as above described extending along the
lever from side to side as these ribs tend to strengthen the levers, but in place of a
continuous projecting rib two or more smaller projections may be formed on each of
the levers to prevent the C-spring moving as above described.
Instead of the ribs or projections being formed on the levers as above described
they may be made separate therefrom and fixed thereto by soldering or by other
means.

Certain Improvements in C-spring Clips for Holding Papers and
for other like Uses.
We, MAURICE MYERS, of Charlotte Street, Birmingham, Warwickshire, Pen
Manufacturer, and JAMES LOWE, of Highfield Road, Saltley, Warwickshiro, Works
Manager, 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 follow-
ing statement :—
This invention has reference to those C-spring clips, for holding papers and for
other like uses, in which two clipping levers of sheet metal making an acute angle
with each other are, near their wider or meeting ends, directly acted upon and pressed
together by the extremities of a sheet stool spring which is C-shaped in cross-section.
Two narrow holes are pierced a short distance apart near the centre of the C-spring
through which the narrow or outer ends of the levers pass, that part of the C-spring
which is between the levers forming their fulcrum. The C-spring is in contact with
the wider part of the levers and thus prevented from moving nearer to their meeting
ends but the act of opening the clip by pressing together the outer ends of the two
levers has a tendency to displace the C-spring by causing it to move along the levers
towards their outer ends which defect it is the chief object of this invention to
overcome.
According to this invention we form a projecting rib along each lever parallel with
and immediately within the extremities or jaws of the C-spring and between the
said jaws and the fulcrum of the levers. As when the clip is in use the extremities of
the C-spring cannot spring over these projecting ribs the C-spring is prevented from
moving out of position towards the outer or free ends of the levers.
We prefer to use on each lever a single rib as above described extending along the
lever from side to side as these ribs tend to strengthen the levers, but in place of a
continuous projecting rib two or more smaller projections may be formed on each of
the levers to prevent the C-spring moving as above described.
Instead of the ribs or projections being formed on the levers as above described
they may be made separate therefrom and fixed thereto by soldering or by other
means.
On the accompanying drawing Fig. 1 represents in front elevation and Fig. 2 in
side elevation a C-spring clip constructed according to this invention; Fig. 3 shews
one of the levers of the same separately and Fig. 4 represents a separate view of the
C-spring of the same; Figs. 5 and 6 represent in front sectional and in end elevation
respectively a modified form of the said clip; Fig. 7 shews one of the levers of a
further modification of the same and Figs. 8, 9 and 10 represent in front elevation,
cross section and sectional plan respectively a further modification of our invention.
The same letters of reference indicate corresponding parts in all the figures.
Referring firstly more particularly to Figs. 1, 2, 3 and 4, A¹ A' are the two levers
and B is the C-spring which presses together the wider ends of the levers A' A³.

page_text: 31 6² are the two slots in the C-spring B through which the narrow or outer ends of
the levers A¹ A pass, the part 6 between the slots 66 forming a fulcrum for the
levers. The act of opening the clip has a tendency to cause the C-spring B to ride
up towards the outer ends of the levers and this we prevent by providing the project-
ing rib a on each lever within and in contact with the extremities of the C-spring and
over which they cannot ride thus maintaining the C-spring in position and adding
strength to the jaws of the lever.
In this example of our invention the ribs are formed by being pressed out of the
body of the lever and they extend from side to side but it will be evident that many
other forms of ribs or projections might be used on the levers for the C-spring to
bear against without departing from the nature of this invention such for instance as
in the clip illustrated by Figs. 5 and 6 where three short projections c¹ are employed
on each lever instead of the continuous rib a; or as in Fig. 7 where the projections c¹
are in the form of tongues pressed and bent up out of the body of the levers A; or as
in the example illustrated by Figs. 8, 9 and 10 where a projecting part d is bent out
of the narrower part of one or both of the levers for the back of the C-spring to bear
against.
We would have it understood that we do not claim broadly the use of every means
for preventing the C-spring moving up the levers as we are aware that previous to
this invention the C-springs have been prevented from moving up the levers by
backwardly projecting tongues formed out of the sides of the C-springs engaging in
holes in the levers; but this arrangement weakens the C-spring whereas by our
invention as we merely require the two narrow holes 61 63 for the levers to pass through,
the strength of the C-spring is not impaired.
Having now particularly described and ascertained the nature of our said Inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is:
1st. In C-spring clips for holding papers and for other like uses forming the levers
that they will so engage with the extremities of the C-spring as to prevent the C-spring
moving out of position substantially as set forth.
2nd. In C-spring clips for holding papers and for other like uses forming the
C-springs with narrow holes for the levers to pass through as described and shewn,
in combination with levers having means substantially as set forth for maintaining the
C-spring in position.
3rd. C-spring clips for holding papers and for other like uses constructed as herein-
before described and illustrated by Figs. 1, 2, 3 and 4; by Figs. 5 and 6; by Fig. 7
and by Figs. 8, 9 and 10 of the accompanying drawing.
