COMPLETE SPECIFICATION.
Improvements in Jars for Milk, Fruit, and the like.
I, JOHN HARTLEN FOWLER, Manufacturer, of Huntingdon, County of Hunt-
ingdon, State of Pennsylvania, in the United States of America, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:
This invention relates to improvements in jars for milk, fruit and the like,
and more particularly to the means for fastening the cover thereon, and the
novelty and many advantages will appear from the following description and
claims when taken in conjunction with the annexed drawings, in which:
Fig. 1 is a perspective view of a jar with my improvements applied.
Fig. 2 is a side view of the upper portion of the jar and cover partly in section.
Fig. 3 is a vertical, cross-sectional view of the same taken in a plane at right
angles to Fig. 2.
Referring by letter to said drawings;
A indicates a jar which in general outline and appearance may resemble that
of an ordinary fruit jar and may be formed from glass or other suitable material.
The mouth of the jar is made Haring as shown at a, and one side of this flaring
mouth is provided with a recess 6 which increases in width as it extends out-
wardly so as to afford a spout, as it were, to facilitate pouring off the contents.
At diametrically opposite points the jar is provided on its outer side and
slightly below its upper edge with a securing lug c. These lugs are of peculiar
form and construction, being of substantially key-stone shape in outline, and
start from a point corresponding with the neck of the jar or approximately so
and extend to near the upper edge of the jar, with a bevel on their outer sides.
Each lug is provided at a suitable altitude on its outer side with a transverse
groove for a purpose which will presently appear.
B indicates the cover which may be of substantially plano-convex form in
cross section, having its under or plain side formed with a tapered and circularly-
depending centre e to correspond with and fit snugly in the flaring mouth of the
jar as better shown in Fig. 3 of the drawings. The cover fits well over the
upper edge of the jar, and is provided with a depending, marginal flange f
which embraces said upper edge; a gasket being in some cases interposed between
the upper edge of the jar and the under side of the cover.
The cover is provided on its upper side at its margin and at opposite points
with spring fastening devices C. These fastening devices, which are composed
of spring wire, are of a peculiar and advantageous shape and are journaled on
the top B. To receive these fastening devices the jar cover should be provided
at the points indicated with two lug journals g which may be formed integral
with the cover and rise vertically therefrom.
In forming the fasteners, a piece of spring wire of suitable gauge and length
is bent about midway of its length to form a loop i of a shape corresponding to
that of the lugs c so as to receive said lugs and spring into the notches & thereof.

page_text: The wire is then carried back substantially parallel as shown at j, thence around
outwardly as at k and back so as to form the bends or loops, after which the
terminal ends are shaped to form eyes m which receive the lugs g.
Я
After thus
shaping the fasteners, the wire is bent at so that the upper portion p will
conform to and lie snugly on the top of the cover and the opposite or lower
portion bearing the loop will receive and lie snugly over the lugs c of the jar.
A jar as thus constructed will be found particularly desirable as a milk jar.
The cover can be quickly applied and removed, and there are no parts liable to
get out of order.
To remove the cover it is simply necessary to spring one of the loops of the
fastening devices out of engagement with its lugs when the-cover can be turned
off and out of engagement with the other lug. To place the cover, the fastening
wires are brought above the lugs and the cover forced down until it seats tightly
on the top of the jar when the wire fasteners will have sprung over the lugs and
into the grooves thereof.
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
1--The jar having the tapered and beveled lugs on its outer side at opposite
points in combination with the cover having the pairs of lug journals at opposite
points on its top, the fasteners, each formed of a single piece of spring wire and
respectively comprising an upper portion adapted to bear on the top of the
cover and terminating in portions pivotally connected to the pair of the lug
journals, and a depending loop adapted to engage one of the lugs on the jar,
substantially as specified.
2-The herein described jar having the flaring mouth with the spout recess
in its inner side and the securing lugs on its outer side; in combination with the
cover having the depending portion on its under side corresponding with the
flare of the mouth of the jar and the flange surrounding the edge of the jar and
also having the pairs of lug journals on its upper side, and the fasteners each
formed of a single piece of resilient wire and respectively comprising the upper
portion adapted to rest on the top of the cover and terminating in eyes mounted
on a pair of the lug journals, and a depending loop at the outer end of the upper
portion adapted to engage one of the securing lugs, substantially as specified.
Dated this 5th day of September 1899.
