JAR AND FASTENER THEREFOR.

SPECIFICATION forming part of Letters Patent No. 793,734, dated July 4, 1905.

Application filed January 12, I905. Serial No. 240,806.

To all whom, it may concern.-

Be it known that I, RoLLAND H. MoCoY, a citizen of the United States, residing at Monmouth, in the county of Warren and State of Illinois, have invented certain new and useful Improvements in Jars and Fasteners Therefor, of which the following is a specification.

My present invention relates more particularly to devices for securing the covers or lids of jars or bottles to the necks thereof, first by an inferior or minor degree of pressure and finally by a superior degree thereof, and to provide these means constitutes the principal object of the invention.

Another object is to provide a device of the kind in which the entire device rests when in use in a plane below that of the upper surface or rim of the lid, whereby convenience and facility in packing, shipping, and stor-.

ing the jars is attained.

A further object is to provide a strong, simple, and durable spring-fastener which may be readily, quickly, and easily applied to or detached from the jar without danger of injury to the operator and without the use of tools and which will effectually hermetically seal the jar.

A still further object is to provide a device whereby when the lever is thrown over into its final position it will be automatically secured in locked placement.

\Vith these and other ends and objects in view my invention consists in certain novel features of construction and combinations of parts, as will be hereinafter fully described, and pointed out in the claims.

Mechanism embodying the preferred constructive forms of and showing the mutual relationship and combinations of the parts forming the subject-matter of my improvements is illustrated in the accompanying drawings, which form a part of this specification, and in whicl Figure l is a sectional view of the cover, packing-ring, and a fragment of the jar, showing the fastening device in its first or released position; Fig. 2, a similar view showing the fastening device in its second position, the lever being turned to such degree that it exerts some, I may say a primary, degree of pressure on the lid or cover; Fig. 3, a similar view showing the fastening device in its final or locked position and as exerting a maximum degree of pressure on the lid or cover; Fig. 4, a top plan of the lid or cover, partly broken away; Fig. 5, a side elevation of the lever, and Fig. 6 a plan thereof seen from below.

The same reference-letter refers to the same part in the different figures of the drawings.

The fastening device comprises three parts viz., the lever A and the opposed transverse arms Band C, which arms when in position extend across the lid or cover D of the jar E and are turned downwardly at their distal ends 6 and 0, respectively, to fit snugly beneath a shoulder e, surrounding the neck of the jar at its upper portion. If preferred,

this shoulder may be dispensed with and the posed openings therein or secured in any desired or preferred manner thereto.

The lever A, which may be fabricated in any desired or preferred manner, consists of a power-arm A and a weight-arm A, slightly broader than the power-arm, which is cut away so that it may rest lower than that of the upper portion F of the lid D. At or near the outer extremity of the power-arm a clip d is turned over and downwardly therefrom and serves to prevent'the two centers from going too far past each other to prevent lateral movement of the lever and to prevent the outer end of the lever being depressed to an undesirable degree. Near the juncture of the arms of the lever is a transverse rib (Z', hav- -the end of the weight-arm and centrally laterally thereof, while the boss 0 is located at the imaginary point of juncture of the Weightarm and the power-arm and to one side thereof or eccentrically.

The arms B and O, which are in allrespects identical and which are preferably of spring-wire, are formed by turning their inner ends about the respective bosses e and e to form eyes Z) c, thence extending them outwardly to near the outer edges of the lid to form transverse members N, thence at O downwardly at an angle to a point P, thence downwardly to form substantially vertical arms Q, and thence inwardly at such an angle that they will form ends or lugs Z) c, which approximately parallel the upper outwardlyextended members N of said arms.

The jar may be of any ordinary construction having means of attachment or securement thereto of the ends or lugs b c of the arms of the fastener and having a seat 9 for any suitable packing-ring or gasket G, which latter may be of any desired form or configuration in its cross-section.

The lid D comprises a main or body portion D, depending into the mouth of the jar and having a plane surface, an upwardly-extended annular portion F, an inclined bearing-face H, and a peripheral flange J, having a face 7', and intersecting the portion F are oppositely-disposed defiles or valleys D".

To operate the device, the parts being in the relative positions shown at Fig. 1 and no pressure or force being exerted on the gasket and lid, the lever may be thrown up into the position shown at Fig. 2. The arm B being fulcrumed on the boss e and the arm 0 fulcrumed on the boss 0, (thus constituting a compound lever,) their ends formed by the eyes I) and 0 will be brought into closer relationship and the points K K of the arms brought into sliding contact with the inclined way or face H of the lid, and because of the strain exerted on the portions 6 0 of the transverse arms a pressure is exerted at right angles to the horizontal plane of the cover, thus exerting sufficient downward pressure to permit of the air being exhausted from the jar without any of the other contents being disturbed or withdrawn therefrom. In this position neither arm B or U will exert more force than the other to draw the free end of the lever in the direction of its trajectory, or, in other words, the lever will be held by said arms at a center while they are exerting an equal draft or pulling force, and by reason of the end of the Weight-arm contacting the surface of the lid it will be held in such position until forced therefrom by the operator. The lever being then thrust into its final or locked position, Fig. 3, the bosses or pintles will have been drawn past the center and past each other, the vertical members will have been drawn to contact a portion of the jar, (but not the lid,) the points K K will have been drawn higher on the inclined face H, the convex projection cof the lever A will be pressed against a substantially central portion of the lid, and an extreme downward force or force "ertically to the horizontal plane of the cover be exerted thereon, whereby the gasket will be compressed to its utmost limit and the jar be hermetically sealed. In other words, the length of the arms remains constant, (see Figs. 1 and 3,) as does the distance between their points I) and 0; but by drawing their inner ends to pass the dead-center and past tions they permit said arms, and thereby the power-arm, of the lever to lie in a horizontal plane not higher than that of the upper portion of the lid, so that the jars may be stored, packed, or shipped one on top of another without danger of breakage from falling or toppling over.

I have hereinbefore stated that the vertical members when the fastener is in its locked position contact a portion of the jar, but not the lid. Neither do the horizontal portions of the arms contact the lid at any point whatever, the only point of contact of said arms being that where the points K K rest and press on the inclined way orface H. Thus eon structed and combined there is no tendency of the outer ends to become disengaged from thejar, as would be if the way or face H were not inclined or if the horizontal or the vertieahportions of the arms contacted the upper and outer edge of the lid.

As shown at Fig. 3, the rib d of the levercontacts one of the arms of the fastener, which latter engages the locking-groove d and will be held thereby in its locked position until released by the operator.

It will be seen that because of the contactpoints of strain being past the center a tend ency to depress the outer end of the powerarm arises and that the clip d, contacting one of the transverse arms and its downward movement being limited thereby, will prevent said end of the lever being depressed farther than is desirable, while at the same time it will be automatically locked in position.

The advantages of the invention arise from integral power-arm and weight-arm, and eecentrically-arranged bosses on opposite sides of the latter arm.
