JAR-CLOSURE.

Specification of Letters Patent.

Application filed April 13, 1908. Serial No. 426,804.

Patented Jan. 11, 1910.

To all whom "it may concern:

Be it known that I, EDGAR C. HILL, a citizen of the United States, residing at Columbus,

in the county of Franklin and State of Ohio,

have invented certain new and useful Improvements in Jar-Closures; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved jar closure.

The object of the invention is to provide a simply constructed cheaply manufactured device for removably clamping an inclosure on a 'ar or other vessel and which may be quic y applied and removed and which is capable of being used indefinitely.

In the annexed drawing forming a part of the specification in which like reference characters refer to like parts throughout the several views and which are for illustrative purposes only and therefore not drawn to scale, Figure 1 ,is a side elevation of the upper end of a jar with the improved clamping device applied thereto and with parts of the jar mouth and lid broken away and the locking member in lowered position; Fig. 2 is a similar view with the locking member in raised position; and i 3 is a detailperspective view of the c amping device de- 1 tached.

.is to of the collar In the embodiment illustrated, this improved clamping device is shown ap lied to a jar A having a groove B forme in the edge of the mouth thereof and having a rubber gasket C disposed thereon over said groove. The lid D is shown provided with an annular rib E on its lower face adapted to fit in the groove B of the jar and to press said gasket C thereinto to form an air-tight closure. This jar is also provided with an annular collar or shoulder F made integral with the mouth thereof to form a laterally extending shoulder G for a purpose to be described.

This improved clamping device 1 is preferably composed of a spring metal strip of a length slig tly greater than the diameter of the jar mouth and lid and is ada ted to span the to of the jar or other vesse to which it be applied. The end 2 of this bar is bent approximately at right an les thereto and has its terminal bent inward y to form a hook 3 for eriigagement with the under side of the jar. The other end of the bar is bent in the same direction as the end 2 but is inclined inwardly and termi nates in a pair of laterally spaced approximately circular lugs 4 between which is pivoted a lug 4 formed at the outer edge of the inner straight portion 6 of the locking member 6. Said end of the locking member extends inwardly beyond the plane of the inner face of the end 4 and is adapted to engage the under side or shoulder formed by the collar or shoulderF of the jar at a point diametrically oppositeto the point engaged by the hooked end 3. This lever 5 is provided with an operating handle portion 7 which preferably extends outwardly with its inner face curved to fit the upper curved surface of the jar body. These bent ends 2 and 4 of the bar l'are formed of a length slightly greater than the combined height of the collar F, thegasket, and the lid. The straight portion 1 of the bar 1 which extends across the jar is curveddownwardly intermediate of its ends to adapt it to closely engage the lid of the jar when the lever is thrown into locking position and thereby firmly hold the lid in air-tight contact with the jar mouth. This bar 1 being composed of spring metal with its straight portion bent downwardly at the center thereof provides for the raising and lowering of the lever 5 and its inner end engagedwith the shoulder G of the jar 1 forms a fulcrum for the lever.

To only temporarily hold the lid or closure upon the ar, the clam ing member is applie in extreme raised position, when the clamping member proper assumes the position indicated in Fig. 2. The upward swingin movement of the locking member is limite by the outer edge 8 of its inner portion 6 engaging with the wall 9 formed at the inner ends of the lugs 4 The clamping member may be removed as a whole from a jar by sliding it transversely therefrom with the locking member in either raised or lowered position.

- I claim-as my invention:

A' clamping member for jar closures comprising a resilient flat metal member having its opposite ends bent in the same direction and the terminal of one of said ends bent inwardly to form a hook for engaging the jar flange, the other end being longer and being inclined inwardly and terminating in a pair of laterally spaced lugs a locking member pivoted between the lugs of said inlowered position, the clamping member being removable as a whole from the jar, with the locking member in either raised or lowered position bysliding it transversely therefrom. y

In testimony whereoi I have hereunto set my hand in presence of two subscribing witnesses.

EDGAR CAMPBELL HILL.
