UNITED STATES PATENT OFFICE.
HAROLD H. STEVENS, OF LOS ANGELES, CALIFORNIA.
4JAR COVER 'AND FASTENER.
SPECIFICATION forming part of Letters Patent No. 696,1 13, dated March 25, 1902.
Application filed April 2, 1901. Serial No. 54,043. (No model.)
To all whom t may concern:
Be it known that I, HAROLD H. STEVENS, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Jar Coversand Fasteners, of which the following is a specification.
My invention relates to fruit-jars, covers, and fasteners, and its objects are lto provide a jar of improved construction and improved means for insuring an absolutely air-tight closure thereof.
The invention consists in a jar of novel construction which avoids the contraction of the mouth, thus facilitating filling and cleaning, in a cover o'f special form cooperating with the jar to afford a tight joint and a neat at-` tractive appearance, and in improved means kfor firmly clamping the cover in place upon the jar.
The characteristic features of the invention will be fully described hereinafter in connection with the accompanying drawings, which form a part of this specification, and the points of novelty will be dened in the appended claim.
In the drawings, Figure l is a side elevation, partly broken away and partly in section, of a fruit-jar, cover, and fastener embodying thev invention; and Fig. 2 is a top plan view of the same.
The reference-numeral l designates the body of the jar, which is cylindrical in form and of the same internal diameter throughout its length, thus avoiding the usual internal annular 'shoulder 'at the mouth and fa cilitating filling, emptying, and cleaning.
the upper end of the jar and slightly beveled on its undervsurface, as clearly shown in Fig. I, for a purpose hereinafter explained. From the upper surface of the lip 2 projects an annular ange 3, the upper surface of which is formed with a continuous depression 4.
The cover 5 is slightly dished or hollowed out on its upper side, and from its under surface depends an annular shoulder 6, which iits snugly within the upper end of the jar.
The periphery of the cover rests ilush with the peripheral edge of the lip 2 of the jar, thus presenting a neat and compact appearance.- I preferably also provide the under vside of the cover 5, outside of the shoulder 6,
with an annular bead 7, which registers with the depression 4 in the lip and coacts there- With to' firmly clamp a gasket 8. This gasket encompasses the outer side of the shoulder 6 and is applied thereto before the cover is placed in position upon the jar.
The cover-fastening consists of a clamp Y9, having its ends 10 turned inward to engage below the beveled surface of the lip 2, which latter permits the hooked ends of the clamp to set close to the outer surface of the jar, as shown, where strain will be more easily withstood. The clamp 9 is formed with a central internallythreaded bearing to receive a clamping-screw ll, formed at its upper end with a thumb-piece 12 and having riveted to its lower enda spring preferably made from a single piece of metal and consisting of a central portion 13, through which the securing-rivet k14 extends, and four radially-projecting spring-arms 15. The thumb-piece 12 of the screw is perforated t0 receive a wire bail 16, which is adapted to straddle the clamp 9 after the screw has been turned to secure the cover, thus locking the screw against movement, or if the jar is used commercially thev hole in the thumb-screw may receive a seal to insure purchasers of the genuineness of the jars contents. The flat sides of the screw may bear any suitable im press or advertising matter.
I preferably make my improved jar of ,zheavy' tough glass to permit special treat- 2 designates an annular lip projecting fromr ment of various fruits and vegetables after the jar is lled.
When the cover is clamped by means of the screw, the springarms distribute the pressure equally, thus reducing to the mini= mum the liability of fracturing the jar' or cover and at the same time affording the tension required to insure a tight joint. Any loss of tension in the spring-arms is compensated for by turning the screw. The concavity of the upper side of the cover affords a more direct resistance for the spring-arms locking-bail extending through said opening than if the top of the cover Were flat. and adapted to straddle the clamp. 1o
I claim- In testimony whereof I aixmy signature The combination with a. fruit-jar and its in presence of two Witnesses. 5 cover, of cover-securing means comprising a HAROLD H. STEVENS.
clamp spanning the cover and secured to the Witnesses: jar; a. thumb-screw extending through the WARREN B. MATHER,
