LID-OPENER.

Specification of Letters Patent.

Patented Sept. 29, 1914.

Application filed January 14, 1914. Serial No. 811,939.

To all whom it may concern:

Be it known that I, SAMUEL SCHMIDT, a citizen of the United States, residing at Farmersville, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Lid-Openers; 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, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to new and useful improvements in lid raisers or devices for raising the metallic lids from metallic boxes and glass jars or jars made of breakable or fragile material which employ metallic lids.

An object of the invention is to provide a lifter for metal covers or lids which may be employed either on the box or container or the lid.

A further object of the invention is to provide a lid raiser which is highly effective owing to its peculiar construction and require but the minimum of manipulation in performing its function as will hereinafter more fully appear from the following description in connection with'the accompanying drawings.

In the accompanying drawings, Figure 1 is a side elevation showing my improved lid raiser on a metal box such as is usually employed to contain shoe polish. In this position the lid raiser is shown ready to be manipulated to elevate the lid. Fig. 2 is a top view with part of the box lid broken away to show the device; Fig. 3 is a view similar to Fig. 1 showing the device in a position with the lid or cover elevated from the box; Fig. 4 is a sectional view of one side of the box and lid and through the axis of the lifter on the line a-a of Fig. 1; Fig. 5 is a sectional view through the lid on the line Z)b of Fig. 1; Fig. 6 is an elevation of a glass jar with metallic cover showing the lid raiser applied to said cover; Fig. 7 is an elevation of the upper portion of said glass jar with the lid raiser moved to a position to elevate the cover from said jar; Fig. 8 i a side elevation of the lid detached from the jar; Fig. 9 is a detached view of the lid raiser removed from the cover of the jar showing the inner side of said lid raiser or that side which lies adjacent to the cover;

and Fig. 10 is an enlarged sectional view on the line 0-0 of Fig. .6.

In a detail description of the invention,

similar reference characters indicate corresponding parts in the description and drawings.

The lid raiser is slightly modified in applying it to the lids or covers of glass jars though in the main the essential features of the device are substantially the same. What variations there are are due to applying the device in one case to the box directly and in the other case to the cover or lid directly.

In Fig. 1, 1 designates an ordinary round box made of tin, aluminum or other suitable material and provided with the conventional marginal bead 2. 3 designates the cover :of said box which is usually made of the samematerial and is provided with the marginal flange 4. Coming now to the device or. lid raiser itself, this consists of a substantially arc-shaped piece stamped froma suitable quality of metal and provided with the following essentials or peculiarities which adapt it to be attached to the box as shown in Fig. l. The device 5 is pivoted to the side of the box by an axial pivot pin 6. The upper edge thereof is straight as at 7 and this edge lies below and in engagement with the flange 4 of the lid. On each side of the straight edge 7, the device isuniformly curved as at 8 to serve as a cam when the device is turned upon its pivot and to engage the flange 4 to elevate the same. The center of the device is recessed as at 9 to cause the body thereof to lie out in a suitable position, for the edge 7 to lie below the flange 4 and for the body to be free from obstruction by the bead 2.

From Figs. 4 and 5, it will be seen that the device is curved or rounded both longitudinally and transversely. The longitudinal curvature, as shown in Fig. 6, causes it to conform to the contour of the side of the box, while the transverse curvature shown in Fig. 4, causes the straight edge 7 to always occupy the position, when the lid is closing the box as in Fig. 4, immediately below the flange 4. These features ofthe device are important for the reason that a proper engagement between the device and the flange of the cover is always insured. The inner side of the device is provided with a boss 10 shown in dotted lines in Figs. 1 and 3 and better shown in section in Fig. 4. This boss is formed by pressing in the metal at the center of the device to prov-ide the recess 9. The terminals 11.01: the boss form shoulders on each side of the pivot 6 which engage with the bead 2 of the box and prevent the device from being moved on its pivot in either direction any farther l enable the lid to be replaced. On each side of the device an outwardly extending ear 12 is provided for the engagement of the fingers in manipulating said device.

Having described the device and its utility in connection with metal boxes in which the flange is provided upon the lids, I will now describe said device as applied to the metallic lids of glass jars of the character which areused to contain preserves, jellies and other substances usually packed in glass or fragile jars. In Fig. 6 the lid 3 is of metal butthe bead or flange 4 is provided on the circumference of the jar 13. In applying the lifter 5 to the metallic lid, as shown in Fig. 6, the recess 9 is dispensed with but in order to cause the lifter or device to stand out in .a proper position to engage the head or flange at on the jar, a boss 14; is depressed outwardly from the side of the lid, as shown more clearly in Fig. 8. This boss 14 is straight as at 15 on its lower side and the pivot pin 6, which unites the device to the lid, passes through said boss 14. The boss 16, which in this case is instrumental in preventing the device from turning farther than is necessary in the operation of lifting the lid or cover, is provided upon the upper rounded margin of the said device. The terminals 11 of the boss 16 engage one or the other side of the boss 14- and limit the movement of the device in either direction when the lid is placed in position, thus causing said device to assume its normal position which is that shown in Fig. 6. In all other respects the device is substantially the same in both cases. As in the case where the 5 lifter is utilized on a metallic box the longitudinal and transverse curvatures thereof are essential when applied to the lid or cover.

I-Iaving described my invention, I claim.

The combination with a box having a circumferential bead and the lid thereof having' a circumferential marginal flange, of a lifter pivoted to said box, and having a central boss through which the pivot extends, said boss terminating in opposite shoulders on the lower edge of said lifter adapted to engage the head on said box to limit the movement of said lifter in either direction.

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

SAMUEL SCHMIDT.
