LID REMOVER Filed Nov. 26, 1962 INVENTOR. Fran/v2 A I SCHMIDLECHNE Z ATTORNEY United States Patent 3,204,494 LID REMOVER Franz A. Schmidlechner, 1342 N. Laurel Ave., Los Angeles, Calif. Filed Nov. 26, 1962, Ser. No. 239,984 11) Claims. (Cl. til-3.44)

This invention relates to an improved device for removing a lid or cover from a jar or other container.

Though various types of devices have been proposed in the past for use in unscrewing jar lids, non of these have proven sufiiciently practical to have enjoyed large scale use and sale. The average home today does not have any such lid removing tool, and as a result most persons still find it necessary to open jars entirely by hand, without an adequate tool of any type.

The general object of the present invention is to provide a lid removing device which is capable of very rapidly and easily gripping the lid of a container, and then with maximum facility turning the lid relative to the container to unscrew it therefrom. The tool has sufficient leverage to assure tight retention of the engaged lid, and yet attains this leverage with an extremely simple structural arrangement. In addition, a tool embodying the invention may be designed to grip lids of any size within a very wide range of sizes, from very small bottle caps to the largest jar lids or covers which are conventionally encountered.

structurally, a lid remover embodying the invention includes twostructures which are mounted for movement relative to one another, and which preferably take the form of two handles adapted to be manually actuated together by a plier type action, with these two structures being connected together by a link which is pivoted at two spaced locations to the two structures respectively. This link then requires bodily shifting movement of one of the structures relative to the other, in a direction causing jaws associated with the structures to grip a jar lid, in response to movement of the two structures relatively toward or away from one another. Desirably, the two structures are interconnected by a second link, pivoted at two additional locations to the two structures respectively, and coacting with the first link and the two relatively movable structure to maximize the gripping effectiveness attained by the device.

To facilitate use of the tool on different sizes of lids, the movable parts may be provided with a plurality of different sets of gripping jaws, forming between the jaws lid receiving spaces of different sizes. Certain particular features of the invention reside in the desired positioning and construction of these various jaw elements or gripping jaw surfaces.

The above and other features and objects of the present invention will be better understood from the following detailed description of the typical embodiment illustrated in the accompanying drawing in which:

FIG. 1 is a perspective view of a lid removing tool constructed in accordance with the invention;

FIG. 2 is a perspective representation of the opposite side of the tool;

FIG. 3 is an elevational view of the tool in its open condition;

FIG. 4 is a transverse section taken on line 44 of FIG. 3; and

FIG. 5 is a fragmentary section taken on line 5-5 of FIG. 3.

The form of the invention illustrated in the figures at includes a first and main part 11 forming a handle at 12, a second handle element 13, and two interconnecting

links

14 and 15. The handle elements are yieldingly urged relatively apart by a spring 16.

ice

All four of the

elements

11, 13, 14 and 15 may be formed of rigid sheet metal, such as steel, deformed to the illustrated configuration. The main part 11 of the device has a primary planar portion 17 lying in the plane designated 18 in FIG. 4, and extending from and end edge 19 to the location of a pair of

gripping jaws

20 and 21 formed at the opposite end of the part. Near the end 19 of part 12, the sheet material forming this part is deformed laterally at 22 (FIG. 5), and then downwardly at 23 parallel to main planar portion 17, to the U-shaped cross-sectional configuration illustrated in FIG. 5. Thus, the

portions

17, 22 and 23 form together the first handle 12 of the device. The cross web 22 of the handle may terminate at 25, at seen in FIGS. 1, 2 and 3.

At the lid engaging end of the device, portion 17 of element 11 may be cut to the shape illustrated best in FIG. 3, to form two

arms

26 and 27. The extremities of these arms are turned to form the two

gripping jaws

20 and 21, extending perpendicular to plane 18 of portion 17, and turned to the same side of portion 17 as is the handle Web 22. As seen best in FIG. 3, the jaw 20 has a main portion 28 and a short inturned portion 29 for biting into and gripping an engaged jar lid. Similarly, jaw 21 has a main portion 30 and a short inturned portion 31 for biting into the lid. At the opposite side of portion 17 of element 11, the material forming this element may form a second pair of

gripping jaws

32 and 33, which are also perpendicular to plane 18, and which have

edges

34 and 35 for engaging and biting into a jar lid being removed.

Part 13 is formed of an elongated strip of rigid sheet metal having a portion 36 lying essentially in the plane designated 119 in FIG. 4, to be parallel to and closely adjacent to portion 17 of element 11. At its extremity, portion 36 of part 13 is turned to form a gripping jaw 37 extending perpendicular to plane 19 and having an edge 38 adapted to grip a lid. At the location designated 39 in the figures, the material of part 13 may be formed slightly laterally to form another portion 40 of element 13 lying in the plane designated 120 in FIG. 4, which plane corresponds to that of portion 23 of element 11. T he outer end of part 13 may be turned to form a handle portion 41 which may extend parallel to cross piece or web 22 of element 11, to facilitate gripping of the part 13 by a user. It is contemplated that a gripping cover of soft resinous plastic material, such as polyethylene or a vinyl plastic, may be provided at 42 on the handle end portion 41 of element 13.

Link 14 may lie in plane 119 of FIG. 4, to be receivable between

portions

17 and 23 of element 11 (see FIG. 5), and is connected by a pin 43 to part 11 for pivotal movement about an axis 44 extending perpendicular to all of the

planes

18, 119 and 120. The opposite end of link 14 is connected by a second pin 45 to portion 40 of element 13, for pivotal movement about a second axis 46 extending parallel to axis 44. The second link 15 is similarly connected at its opposite ends by

pins

47 and 48 to parts 11 and 13 respectively, for relative pivotal movement about two additional axes 49 and 50 (FIG. 4) extending parallel to

axes

44 and 46. To enable connection of line 15 to both of the parts 11 and 13, the link may be deformed slightly at 51, so that its upper portion may lie in plane 119, while its lower end may lie in plane 120. Also, it is noted that link 15 is preferably substantially shorter than link 14, in order to optimize the gripping eifectiveness of the device. Desirably, link 15 is not more than about one-half as long as link 14 (for best results approximately equal to one-half that length), with the links of course being measured between their respective

pivotal axes

44 and 46, and 49 and 50.

Spring 16 for yieldingly urging parts 11 and 13 relatively apart may be an essentially conventional type of spring, having a coil 52 disposed about an outwardly projecting portion of pin 48, and having an arm 53 bearing in a counterclockwise direction against link (as viewed in FIG. 3) and a second arm 54 hearing in a clockwise direction against part 13. The ends of the arms may of course be received in suitable notches formed in the engaged parts.

The inner surfaces of

parts

13 and 14 are pro /ided with serrated gripping irregularities or

teeth

55 and 56 for engaging a small size bottle cap, and adapted to coact in gripping relation with either of two similar sets of gripping

teeth

57 and 58 formed on

portions

17 and 23 respectively of part 11. As will be apparent from FIG. 3, portion 23 of element 11 is cut away relative to portion 17 sufficiently to enable teeth 58 to be recessed farther away from

teeth

55 and 56 than are teeth 57. The extremity of link 14 is turned beyond pivot pin 45 to form a gripping jaw 59, which extends perpendicular to

planes

18, 119 and 120, and has an edge 60 engageable with and adapted to grip a jar lid.

To now describe the manner of use of the device, assume that first of all it is desired to grip a jar lid of the size illustrated at 61 in FIG. 3, or somewhat smaller than this size. For this average size lid, the

jaws

2d, 21 and 37 are employed, with the lid being received between these jaws as shown in the figure. After such positioning of the lid, the user of the device manually actuates handles 41 and 24 relatively together, as to the broken line position of handle 41 represented at 41a in FIG. 3. This pliers-type actuation of the handles relatively toward one another acts through

links

14 and 15 to require or cause leftward bodily movement of element 13 relative to element 11. As a result, jaw 37 closes leftwardly toward jaws 2t) and 21, to tightly grip the lid so that it may be turned relative to the jar or other container by which it is carried. In most instances, jaws and 21 will grip the lid primarily through the gripping edges 63 and 64 of their

short lugs

29 and 31, and jaw 37 will grip the lid primarily through its edge 38. These

edges

38, 63 and 64, as well as the previously mentioned edges 34, and 6d of

jaws

32, 33 and 59, desirably all extend parallel to the

various axes

44, 46, etc. In some sizes of lids, the inner surfaces of

portions

28 and 30 of

jaws

20 and 21 may engage the lids, or a series of teeth 65 formed on jaw 37 may engage the lid at the location of that jaw. When the handles are relatively close together, jaw 37 may move to a minimum diameter condition such as that represented at 37a in FIG. 3.

For gripping larger lids, as represented at 66 in FIG. 2, I may utilize

jaws

32, 33 and 59, which are spaced considerably farther apart than are

jaws

20, 21 and 37. J aw 59 is actuated relatively toward

jaws

32 and 33 by the same type of handle closing movement discussed in connection with the first set of jaws.

For very small bottle caps and the like, as represented at 67 in FIG. 3, the gripping

surfaces

55, 56 and 57 are employed, which surfaces automatically close toward one another to grip a lid upon actuation of element 13 toward element 11. Slightly larger lids or caps, as represented at 68, may be gripped by

surfaces

55, 56 and 58.
