Improvements in Fruit Jars or Bottles.
1, JOSEPH LOUIS DE STRIGAR, residing at La Salle, in the County of La Salle, and
State of Illinois, U.S.A. Manufacturer, 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 improvements in fruit jars, and it has for its object to
improve the fasteners for the covers, so that said covers may be quickly and readily
appliod and as readily removed without any great care or exertion on the part of
the operator.
A further object of the invention is to provide a jar and cover which may be
easily constructed, and the parts adapted for easy application in applying the cover.
Other objects and advantages will appear from the following description and claims
when taken in conjunction with the accompanying drawing in which: "
Figure 1, is a perspective view of a frait jar constructed according to my
improvements.
Figure 2, is a vortical sectional view of the upper part of the jar and cover.
Figure 3, is a transverse sectional view taken in the plane indicated by the dotted
line x, x, of Figure 2. and:
Figure 4, is a perspective view of the metallic fastener.
Referring by letter to said drawings:
A, indicates the jar or bottle which may be made of glass or other suitable material.
This jar or bottle as the case may be is provided adjacent to its mouth with an
external annular flange a, which is preferably beveled as shown to receive a rubber
ring or gasket b, and form an under shoulder c, for the grasp or engagement of the
metallic fastener or bail C, as will be presently described.
B, indicates the cover, which may be also composed of glass or the like. This
cover comprises a horizontal top e, having a circumferential depending flange,
to bear upon the annular shoulder of the jar and the interposed gasket, and is
provided on its upper side at diametrically opposite points with two oppositely
directed curvilinear planes, or elevations g, which are so disposed as to leave between
then an interspace h. The cover is also provided with circumferential grooves or
corrugations i, so as to afford a conveniont means for grasping the cover to turn
it, in releasing the same from the fastener, and also securing the same on the jar
or bottle.
C, indicates the fastener, which is preferably composed of metal. This fastener is
of a form substantially as shown, and is composed of a single piece of material,
comprising a horizontal portion j, having its ends bent downwardly as at k, and thence
inwardly as at l. From these inward bends the material of one branch is carried
horizontal and curvilinearly in one direction as shown at.m, preserving the curvature
of the jar, and the opposite terminal is carried in a similar manner but in an opposite
direction as shown at n.
By this construction it will be seen that I form a very broad bearing for the
engagement of the fastener, which will insuré a firm engagement of the same with
the jar.
The fastener is preferably composed of square wire, the diameter between the
horizontal curved ends being a little smaller than the diameter of the jar under the
shoulder, so that in applying the fastener, the curved ends will spring into place and
fit annaly

page_text: In operation, after fruit (which is usually hot) has been placed in the jar, and the
gasket has been placed on the annular shoulder, the cover is placed in position,
the fastener is then placed straddling the cover between the inclined planes or
elevations thereon, with the curved terminals beneath the shoulder. The cover should
then be grasped and turned so that the metallic fastener will ride over the inclined
elevations, when the cover will be drawn tightly upon the shoulder with the gasket
interposed, and the result will be that the cover will be tightly or hermetically closed
upon the jar.
While I prefer to turn the cover as described, yet the fastener can be turned
'instead of the cover when a similar result will follow, but in opening the jar, if the
cover is very tight as is often the case, the fastener may easily be turned off the
inclined ridges or planes; besides one may know if the jar is properly sealed by
simply turning the fastener.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
The jar or bottle having the external annular flange a, at an intermediate, point in
the height of its neck, forming an upper and a lower shoulder; in combination with
the gasket surrounding the neck and arranged on the upper shoulder, the cover
adapted to embrace the mouth and baving the depending flange, to bear on the
gasket.on said upper shoulder, and also having the two oppositely directed' curvilinear
inclined elevations on the upper side, and the metallic fastener comprising the
horizontal portion j, and the two depending branches &, terminating in the lateral and
curvilinear branches turned in opposite directions to engage the lower shoulder of
said flange, 'substantially as specified.
