1 Claim.

The present invention relates to shears, particularly heavy type shears such as pinking shears and is a division of patent application Ser. No. 253,074, filed January 2'7, 1939, Patent 2,204,071, June 11, 1940.

Special objects of the invention are to construct a shear, particularly pinking shears and the like, which are largely intermittently used, so that when placed on a work table they will stand up in position to directly receive the fingers of the user and to accomplish this without adding to the bulk of the shears or in any way interfering with the free and proper use of the shears.

These and other desirable objects are attained by the novel features of construction, combination and relation of parts hereinafter described, illustrated in the accompanying drawing and broadly covered in the claim.

The drawing illustrates one practical commercial embodiment of the invention. Structure however may be modified and changed as regards this present disclosure, all within the true intent of the invention as expressed in the claim.

Fig. 1 is a side elevation of shears having the invention incorporated therein.

Fig. 2 is an enlarged vertical sectional view as on substantially the plane of line 2--2 of Fig. 1.

In the drawing, there is shown a shear of typical design having upper and lower handles 3, 4, and which in the closed position of the blades stand in the approached condition shown, ready to conveniently receive the thumb and fingers of the hand.

In order that the instrument will stand in this relation when placed upon a work table or the like, there is provided, under this invention, special supporting means in the form of lugs 5, 6, extended downward from the hub portions 1,8, of the two blades to line up in the closed position of the blades and thus to combine as a rest or support equivalent to the full width of the hub portions, Fig. 2. The hubs of pinking shears and the like are usually necessarily rather heavy and thick and hence lugs of the full thickness or depth of the hubs will provide a base of ample width to support the shears in the upright position shown.

The two supporting lugs and particularly the outer extremities of the same combine, with the bottom edge of the lower handle at 9, or with the lower edge of the shear blades at II), to form a substantial three point support or, in some instances, with the handle and blade edges 9, I 0, at the same level to form a four point support.

By making the support lugs of small dimensions such as indicated, they add no appreciable weight to the shears and by extending them only to substantially the lowest outline of the blade hubs, they add no appreciable bulk to the shears and do not hinder the use of the shears in cutting various materials or in sliding over a table or support on which the work is being cut,

These lugs lining up as they do, only when the shears are closed, provide a safety feature in that they remind the user to fully close the shears before putting them down, so that they will stand up in position to be quickly grasped for the next use.

Locating the supporting lugs on the hub portions also takes advantage of the greatest width of the shears, and avoids any increase in the overall thickness of the shears.

Adjustment of the shears for tension regulation and the like, does not impair the supporting effect, because any relative separation or approach of the hub portions in such tension adjustments merely increases or slightly reduces the width or lateral extent of the supporting base.

In the illustration, the tension adjustment is similar to that disclosed in the parent patent application above identified, involving coa-ctin-g nut and screw elements ll, l2, with the first slidingly keyed in the hub of one blade at l3 and rotatively engaged in the hub of the other blade at M, and the other screw element adjustablyheld in the same, first mentioned hub by a surrounding spring coil IB, non-rotatably secured to that hub at I 5.

What is claimed is:

Shears comprising blades having handles and provided with opposed hub portions, an adjustable screw fastening extending through said hub portions, said hub portions having annular rims surrounding the exposed ends of said screw connection and radial extensions on said annular rims forming rests for supporting said shears in upright position with the handles ready to receive the fingers of a hand, said radial extensions being in the form of lugs projecting down below the lower edges of the blades and registering in the closed position of the blades and extending substantially the full thickness of the assembled blades and thereby providing a broad supporting base capable of maintaining the shears in the upright hand-grasping position.
