PROVISIONAL SPECIFICATION.
Improvement in Jar Lid Fasteners.
We, FRANZ GUILLEAUME, Manufacturer, and EWALD GOLTSTEIN, Engineer,
both of Bonn, in the Kingdom of Prussia, do hereby declare the nature of this
invention to be as follows:-
Our invention relates to the means for securing the lids of jars, such as are used
for keeping preserves.
The device which we employ for this purpose consists in a metallic clamp having
the form of a star with three or more radii or arms, which are bent downward at
their ends and then inward again so as to form hooks. Moreover the clamp is made
of such resiliency that two of the arms may be spread apart for allowing the clamp
to be slipped over the lid of the jar. Preferably the same is constructed of a single
wire bent to the required shape.
The jars to which these clamps are to be applied, must be provided below their
rim with a peripheral collar or shoulder with which the said hooks may engage.
After the lid has been placed on the jar together with an india-rubber tightening-
ring, the clamp is sprung over the lid and the top of the jar, so that the hooks
catch under the collar or shoulder of the latter. In order that the clamp may
exercise a resilient pressure on the lid, its central portion is bent downward in a
curve, or the lid is made convex or formed in the centre with a projection for the
clamp to bear on.
The jar is by preference molded with a conical rim forming at its bottom the
said shoulder, while the lid has a rim fitting over the conical rim of the jar with
some space, in which is placed the india-rubber tightening-ring.

Improvement in Jar Lid Fasteners.
We, FRANZ GUILLEAUME, Manufacturer, and EWALD GOLTSTEIN, Engineer,
both of Bonn, in the Kingdom of Prussia, do hereby declare the nature of said
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:—

Fig. 1 is an elevation of the upper portion of a jar provided with our
lid-fastener.
Fig. 2 is a vertical section through a portion of the jar and the lid.
Fig. 3 is a top view corresponding to Fig. 1 and Fig. 4 a view from the right
hand side of the jar relatively to Fig. 3.
Fig. 5 shows the clamp detached from the jar.
Fig. 6 represents to a larger scale the joint between the jar and the lid.

The jar is molded with the conical rim, forming at its bottom the shoulder 6ª
and provided with a groove in which is placed the india-rubber ring d, serving to
produce a tight joint between the jar and the lid a. The clamp e c is made of
wire bent to form a star with, three arms, whereof the arm c consists in a doubled
portion of the wire, while the arms c'e' consist each in a single part. The ends
of the arms are bent downward and then inward so as to form hooks adapted to
grasp over the lid a and to catch with their tips e under the shoulder 6*.
Towards the middle of the clamp the arms c c are curved downward to press on
the lid.
For applying the clamp, the lid is pressed well down upon the jar, so that the
hooks on arms c¹ are capable of engaging with the shoulder 6 when the arms bear
on the lid. The clamp is then pushed from the side, i.e. in the direction of arrow x,
over the lid, the arms c' bending apart and then springing together again, until
arme touches against the lid, whereupon a pressure in inclined direction puts the
hook on arm c also in engagement with the shoulder 6, the lid being then secured
through the pressure of the central portion of the clamp. For removing the clamp,
it only requires to be drawn off in the opposite direction.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :
The combination, with a jar having a peripheral shoulder and a lid to said jar,
of a lid-fastener consisting in a resilient clamp constructed of a single wire bent
into the shape of a star having three or more arms, the ends of which form hooks
adapted to grasp over the lid and to engage with the said shoulder, while
towards the middle of the clamp the arms are formed to press on the lid, substantially
as described.
