I show, HlOngfthe line 5 5 of Fig. 2, and, for example, that the gripping ends of t-he Fig 6 is a sectional view partly in eleVaarms l2 and 14 are substantially flat griptOYl LlOIlg the HHG 6 6 0f Fig- 9- ping ends; while at the end of the arms 13 K In accomplishing the invention in general and 16 I 1p1-Ovide recesses 29 of suitable shape I QFOVG e Unir' 0f 21H11 members pivoted to facilitate gripping round or square obiiitermediate the ends, thus providing a pair jects such as small screws, pins, or other of on keach side of the pivot point. round or odd shaped articles. The arms Spring means is provided adapted to be dise .l2 and llibeing fiat are principally adapted posed immediately in line with the pivot for gripping relatively flat articles such as pair of arms and the tool can' be used su'bstantially in the Way that an ordinary pair of tweezers or similar tool is used. The spring assembly, however, may bemoved to either side of the pivot to apply tension to either pair of arms. In Fig. 1 the 'arms 12 f and 14 are under tension while in Fig. 2 the arms 13 and 16 are spring pressed. Looking at! Fig, if a small article is to be gripped by the formed ends of the arms 13 and 16, the other pair of arms is brought closer together by pressure, the article to be handled, for example, a small screw, is placed between the ends of the arms 13 and 16 and the hand pressm'e on the arms`12 and 14 is released. Thespring assembly will then'hold the arms 13 and 16 together, thus securely holding the screw o r other small part between the spring pressed' arms. r

The tool is of vconsiderable utility in handlingfrelatiyely small springs for example having loops on their ends which are'for eXample to be engaged over a pair of pins. Such al spring would be similar to the springs 26 and Q7 used herein as a part of the tool. In this case with the tool adjusted as shown in Fig. 2 the arms 12 and 14 would-be pressed together and the/ends of the arms 12 and 14 inserted through the loops at the end Vof the spring. Pressure on the arms by the iingers would then be released, and a small spring would be expanded and helden the ends of the arms. When the spring was to kbe placed overv a pair of pins then, for ex- "a'mple,1t would only be necessary to hold the arms 12 and 14 in alignment with the pins or posts for the small spring and then force the small spring off the ends of the arms on to the posts by a suitable tool.

I have disclosed a speciiic embodiment of my invention, but it is understood that I am not restricted to the specific form shown, the invention being limited onlyvby the scope of the appendedclaims.

What I claim is Ynew and desire to protect by United States Letters Patent is 1. In atool of the cliaiactel'desci'ibed a` pair of arm members, means for Vpivoting the .arm .members intermediate their ends, a

7 intermediate their ends, a pivot V disposed between the two projections to pivot the members intermediate their ends, a spring assembly disposed around both arm members, and means for supporting the spring assembly on the arm members either in alignment with the pivot or at either side thereof.

3. Ina tool ofthe character described, a pair of arm members, projections on the arm members intermediate the ends, means for pivoting the two arms together at said proj'ecticns,aspring assembly comprising a pair of pins connected together by a pair of springs, and means for supporting said spring assembly across the two members so that said pins are in alignment with the pivot or at either side thereof.

4. In a tool of thecharacter described, a pair of arm members, projections onthe arm members intermediate thek ends, means for pivoting the two arms together at'said projections, aspring assembly comprising a pair of pins connected together by a pair of springs, and means for supporting said spring assembly across the twoemembers so that said. pins are'in alignment with the pivot or .at either side thereof, said means comprising a plural-ity of indentations in alignment with each other on each of the arm members.

5; a tool of theV character described, a pairof arm members `eachhaving its ends shaped to permit cooperation between the arms at each end of the two members for, grasping a relatively small article, projections on each arm member intermedia-te the ends thereof, means for pivoting the arm members together at said projections, spring means for .pressing the arms together, and4 means for supporting the spring means in alignment with the pivotlor at either side thereof whereby spring pressure is applied to either pairof arms. f j

6. In a tool of the character described, a pair of arm members each having its ends shaped to facilitate grasping relatively small articles, a relatively thin projection on one of said arm members intermediate the ends thereof, arelatively thin projection on the other arm member positioned to lie along the projection of the first arm member and maintain the two varms in alignment, pivot means for.l the arm members comprising a member having an internally threaded shank extending through apertures in the two projections, a Washer `and a machine screw ex.- tending through the washer 'into said internally .threaded shank, v.spring means. for pressing thejtwo arm. members ntoward each other, and means for supporting said spring means either in alignment with said lpivot or at either side thereof. y y

7. In a tool of the character described, a pair of arm members each having its ends shaped to facilitate grasping relatively small articles, a relatively thin projection on one of said arm members intermediate the ends thereof, a relatively thin projection on the other arm member positioned to lie along the projection of the first arm member and maintain the two arms in alignment, pivot means for the arm members comprising a` member having an internally threaded shank extending through apertures in the two projections, a Washer and a machine screw extending through `the washer into said internally threaded shank, a spring assembly comprising a pair of pins, and a pair of springs engaging the ends of the pins, and means for supporting said spring assembly on the arm members so that the pins are in alignment either with the pivot or in alignment at either side of the pivot.

8.v In a tool of the character described, a pair of arm members each having its ends shaped to facilitate grasping relatively small articles, a relatively thin projection on one of said arm members intermediate the ends thereof, a relatively thin projection on the other arm member positioned to lie along the projection of the rst arm member and maintain the two arms in alignment, pivot means for the arm members Comprising a member having an internally threaded shank extending through apertures in the two projections, a washer and a machine screw extending through the Washer into said internally threaded shank, a spring assembly comprising a pair of pins, and a pair of springs engaging the ends of the pins, and means for supporting said spring assembly on the arm members so that the pins are in alignment either with the pivot or in alignment at either side of the pivot, said means comp-rising a plurality of recesses in the arm members.

In witness whereof, I hereunto subscribe my name this 2nd day of November, 1931. ALEX DE SCHEBEKO.
