Specification of Letters Patent.

Patented July 29,1919

Application filed December 2, 1918. Serial No. 265,011.

To all whom it may concern:

Be it known that 1, JOHN CHRISTOPHER NIonoL, a subject of the King of Great Britain, residing at the town of Perth, in the county of Lanark, Province of Ontario, Canada, have invented new and useful Improvements in Closures for Jars or Recepta-cles, of which the following is a specifica tion.

The invention relates to improvements in jar closures or the like, described in the present specification and illustrated in the drawings that accompany the same.

The invention consists essentially of the novel arrangement and construction of parts whereby a Spring member, in combination with a container having a flange formed therearound and lugs formed beneath and on said flange, on the side thereof, is adapted to efficiently secure a suitable top or cover thereon, at the same time allowing of the releasing of said top when desired to remove the contents of the container.

The objects of the invention are to provide simple inexpensive and efficient means whereby the tops or covers of containers may be securely'held in place, quicklyand easily relieved with the fingers when desired.

In the drawings, like characters refer to corresponding parts throughout the several figures.

Referring to the drawings Figure 1 is an elevation view of a container showing a spring member in closed position.

Fig. 2 is an elevation view of a container showing the spring member in disengaged position for removing the top. V

Fig. 3 is a view of a modified form of the spring member without the hinged part.

Fig. 4 is a perspective view of the spring member showing details of the hinged part.

Fig. 5 is a top view of the cover showing the spring and lugs holding it in place.

My invention is here shown to apply to a glass jar, only, and it will be readily understood, however, that it may be applied to receptacles made of metal or any suitable substances.

1- is a container, here shown as glass. The said container has formed therearound the flange 2, said flange being at or near the top as desired. 3 are lugs formed on the side of the container, beneath the flange 2.

' purpose of which will be hereinafter described.

l is the customary top or cover which may be flat and may be provided with flanges to engage the inside of the container, as desired. The said top has centrally formed thereon the teatlike projection and four lugs 5 at or near the circumference thereof, two on each side of the spring to hold it in place.

The means I provide for securing the top or cover to the container, consist of a curved member 6 which forms a bridge piece across the top of the container, and presses on the projection 5, and held in place by the lugs 5.

This spring member is made of a length of steel or metal of any desired width, and is slightly curved upwardly, one end of which is bent downwardly at 7 and then up- Wardly on the under side of the said spring, at an acute angle or V shaped form, at 8, thus forming the gripping arms 9 and 10, the latter engaging the under side of flange 2 thereby holding the top or cover securely fastened to the container.

The other end of spring 6 is angularly bent at 11 to form the hinge 12.

The arm 9 of the spring is made longer than the arm 10, so as to provide, at 8, a good hold to disengage the latter from the flange 2.

The hinged ortion 12 of the spring is held in place y the lugs 3,one placed below the hinge, and one on each side of the hinged part of the spring on the flange 2.

Awire band 13 is placed around the container between the flange and the lugs 3,. said wire passing through the hinge 12 and serving as a pivot to said hinge, and also holding the hinged portion of the spring secured to the container.

This spring, on account of its curved shape, will exert a greater pressure than a. straight spring would. The pressure will be centrally distributed to all parts of the top or cover which will therefore be securely and firmly held to the container. If a metal container is used, the lugs 3 and the wire 13 can be dispensed with, and the hinged portion soldered or otherwise fastened to the container.

A modified shape of the spring may be used, if desired, as shown in Fig. 3, by making both clamping arms, 9 and 10, alike,

and dispensing with the hinged part 12 and; the Wire 13; both clamping arms, 9 and 10, Would then engage the underside of the flange, and could also be easily released with the fingers as mentioned above.

While I have shown and described substantially only one form of the invention, it is nevertheless to be understood that the design of the container as well as the cover or top, might be modified, and other changes be made without departing from the spirit and scope of the invention.

What Ielaim is:

In a jar closure or the like, in combina tion, a container having a flange formed,

amazes therearo'und, a plurality of lugs on the c0Ii-' tainer and flange, a top, a projection, a curved spring member hingedly secured between aforesaid flange and lugs, adapted to press on the said projection and held in place by lugs formed at or near the circumference of the top, clamping V shaped arms provided at its other end to engage the under side of said flange, a Wire band placed around the container, under the flange, serving as a pivot to the hinge, and holding spring member in position.

In testimony whereof I have affixed my signature. 7 JOHN CHRISTOPHER NICHOL.
