Application filed March 29, 1899. Serial No. 710,977. (No model.)

To @ZZ whom, it may concern/.- v

Be it known that I, ELISHA HAYNE, a citizen of the United States, residing at Mount Pleasant, in the county of Jefferson and State of Ohio, have invented certain new and useful Improvements in Fruit-Jar Closures; and l do hereby 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 saine.

This invention relates to closures for fruitjars and analogous articles, the purpose being to secure and maintain a tight joint between the jar and the cap and to obviate the ordinary screw-thread connection provided between these parts, and which is objectionable chiefly because of the difficulty frequently experienced in removing the cap, not easily kept clean, and comparative expense of manufacture.

This invention provides a simple means for securing the cap to the jar and exerting a pressure thereon, so as to prevent loosening and allow for contraction and expansion.

The invention consists, primarily, of corresponding lugs at opposite sides of the jar and cap, said lugs being inclined at their outer edges and separable horizontally, and a yoke to span the cap and the sides of the upper portion of the jar and engage with the lower edges of the lugs.

The invention also consists of the details of construction, novel features, and combinations of the parts, which hereinafter will be more particularly set forth, illustrated, and finally claimed.

The drawings illustrate the preferred embodiment of the invention, yet it is to be understood that within the purview of the invention various changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages thereof.

In the drawings, Figure l is a perspective View of a jar, showing the application of the invention. Fig. 2 is a detail section of the upper portion of the jar. Fig. 3 is a view similar to Fig. 2 as seen from a point at right angles thereto. Fig. 4 is a detail perspective view ofthe cap. Fig. 5 is a detail view of a different form. Fig. 6 is a detail View in pere spective of the yoke-clamp.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The jar l and cap 2 may have any desired form and be constructed of glass, porcelain, or other material commonly employed in the manufacture of articles of this character. An outer flange 3 is provided near the top edge of the jar. A vertical rim 4 rises above the flange 3 and receives the pendent flange 5 of the cap 2. A gasket 6, of rubber, felt, paper, or like material, surrounds the vertical rim et and rests upon the top side of the flange 3 and comes between the latter and the pendent -I flange 5, so as to secure atight joint between the cap and jar after the parts have been properly positioned and secured. A central depression 7 is formed in the top side of the cap 2 and receives a crimp or bend S of the yoke-clamp and centralizes the latter and assists materially in preventing casual displacement of the yoke-clamp after the latter has been fitted upon the jar. The top side of the cap or closure is convex and slopes equally in all directions from a central point. A groove l0 extends diametrically across the top side of the cap and forms a seat for the horizontal member of the yoke-clamp.

The yoke-clamp comprises a horizontal member ll, vertical members l2, extending from the extremities of the horizontal meinber in the same direction and about in parallel relation, and bent ends 13, the latter making positive engagement with the jar when the parts are assembled. This yokeclamp is constructed, preferably, of springwire of any desired cross-sectional outline and of a gage corresponding to the size and required strength of the clamp. The end portions of the horizontal bar are deflected from a normal position when the clamp is operatively applied and normally tend to regain their relative primal position, and this deflection of the yoke-clamp creates a tension thereon which compensates for any contraction or expansion of the parts due to climatic changes or variations in temperature.

The jar is provided at diametrically oppo- IOO 'terminals 15.

site points with lugs 14, which incline outwardly and downwardly at their outer edges or faces. Theselugs extend from the top side of the cap to the bottom edge of the flange 3 and are wholly exterior thereto and are separated upon a line corresponding with the joint formed between the flange of the cap and the flange 3 of the jar. The yoke-clamp has the bent ends 13 at right angles to its plane and projecting in opposite directions therefrom and formed with upwardly-bent These bent ends 13 are adapted to ride upon the inclined edges of the lugs 14 and spring thereunder after clearing the lugs, the latter coming between the vertical members 12 and the upwardly-bent terminals 15.V This construction prevents accidental displacementof the yoke-clamp when positioned. The horizontal bar of the yoke-clam p is deflected by the application of direct pressure thereto, the bent ends 13 riding upon the inclined edges of the lugs 14 when pressing the yoke-clamp down upon the cap. The vertical members 12 yield outward as the yoke-clamp is pressed home, and after the bent ends 13 clear the lower ends of the lugs said membersspring inward and cause the bent ends 13 to engage with the under sides of the lugs and apply the fastening. The lugs 14 have vertical grooves 16 intermediate of their sides to provide seats for the vertical members 12 of the yoke-clamp when in position. The lower edges of the lugs 14 slope inwardly and upwardly to prevent displacement of the bent ends 13 of the yokeclamp when engaged therewith. Y

As shown in Fig. 5, the lugs are not very wide and the vertical members of the yokeeease'i' clamp lie at one side thereof, whereas in the form of lugs vertically grooved between their sides the vertical members 12 are seated in thesaid grooves and preclude any possible .turning of the cap after the parts are assemin alinement and interlock therewith, substantially as described.

2. The combination with a jar and cap having oppositely-disposed lugs inclined outwardly and downwardly at their outer edges and divided horizontally, part being formed with the jar and part with the cap, the said lugs having their inclined edges vertically grooved, of a spring yoke-clamp comprising ahorizontal and vertical members, the latter having their terminal portions bent to ride upon the combined inclined edges of the divided lugs when brought in alineinent and engage thereunder, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
