ApplicationJune 9; 1950,.Serial N 0. 167,003

; 2"Claims. (01,751 41) This: invention-v relates burli ng. tools; and: m e pa t cu r to; a handtool iorxpick ns :and' cutting excessive and; extraneous materialfrom wovenfabric,

, is amon -r the 110bJect cf.-the; invention. ,to-

p ov hur in .tcol in the for'mxo a" pair of. wee ersh tins o pos pu tin -blades th r n so, that the -slubs,;threads;-;thread1 ends,- knots: and other misplaced or extraneous material in a;

pieceofwoven fabric can be picked out and cut away to leave the fabric in a smooth and finished condition, which provides .theitwee'zers and the cutting blades or shearsin thesametoolso that it is not necessary to change tools foncuttingand picking operations which is so designed that the tweezer points'close before the cutting blades so that a-thread can be held byxthe tweezerswhile being cutoff; at the, surface. of ,the; fabric. .by -the cutting blades, in which the cutting blades .are so shaped and positioned that they will cut fibres at the surface of the fabric but cannot dig into the fabric to cause injury thereto, and which tool is simple, strong and durable in construction, economical to manufacture, easy and comfortable to use, and positive and effective in operation.

Other objects and advantages will become apparent from a consideration of the following description and the appended claims in conjunction with the accompanying drawing wherein:

Figure 1 is a side elevational view of a burling tool illustrative of the invention in operative position on a piece of fabric;

Figure 2 is a top plan view of the tool as illustrated in Figure 1;

Figure 3 is a, cross sectional view on an enlarged scale on the line 3-3 of Figure 1; and

Figure 4 is a perspective view of the tool showing the manner of using the tool for removing a loose thread from a piece of woven fabric.

With continued reference to the drawing, the tool comprises two elongated fiat legs II! and II having their end portions permanently welded together at one end of the tool, as indicated at I2, and extending in side by side relationship from such welded together portions. At their opposite ends both of the legs I and I I are symmetrically tapered along straight edges, as indicated at I3 and I4 in Figure l, and terminate in sharp points I5 and I6.

The legs III and I I are formed of specially heat treated spring steel to render them highly resilient and extremely hard and are bowed outwardly away fromeach other so that the points I5 and I6 are resiliently held apart, as particularly illustrated in Figure 2.

The tool is of a size to fit comfortably into the hand ofan operator and the points I5 and I6 can be squeezed together by thumb and finger pressure on the outer sides of the legs I0 and II to grasp a. thread. or;.--fibre;-mass; .on a, piece:-.of;-' woven fabric and mill-such thread or fibre mass outwardly from the-surface of the .fabric;- The, points may also .be used foryremoving extraneous;

.- material ,from the cloth, such asfragments :of's

burrs, stemsor other extraneous-material which may have been included in the fibre fromwhichethe fabric was woven.

Twocutting blade-formationsd I1 and- I 8 are provided, one on 1 each leg; and are. disposed; at. the same side of .thetooldn mutually opposed res-i lationship to each ,other. ,The L 1tting blade; fore mation' I 1 extends .-,long itudinallyof the leg; I IL intermediate the length of the tapering; straight;- edge I4 of this leg and, adjacent-thepoint15, while the blade formation" I8 is :provided on the}; corresponding tapering straight edge ,1 of the leg; I] and is substantially." coterminous with the: for'mationJfI. I f V While the, dimensions may be. varied w-ithin,

reasonable limits without in anyway exceeding the scope of the invention, it has been found that a total length of a tool of slightly over four inches and a displacement of the adjacent ends of the cutting blade formations from the corresponding points I5 and I6 of approximately one' half inch have been found to provide excellent results in use. a

As is particularly illustrated in Figure 3, each of the cutting blade formations I 'I and I8 is integral with the corresponding legs I0 and II and the cutting blade formations are of V cross sectional shape providing mutually opposed cutting edges at the inner sides of the legs. The outer edges of the blade formations are fiat and are in alignment with the corresponding straight edges of the legs I0 and II so that the tapering straight edges of the legs provide a guide or stop which precludes the blade formations from digging into the fabric and injuring the fabric or severing the threads of which the fabric is woven. The cutting edges of the blade formations, however, are flush with the flat outer surfaces of the formations so that the blades will cut at the surface of the fabric and completely remove any excretions or projections from the surface of the fabric leaving the fabric in a smooth condition.

In using the tool, large bunches or knots of material and extraneous material may be picked from the fabric by the tweezer points I5 and I5 and smaller bunches and knots of fabric and loose threads may be cut off at the surface of the fabric by the cutting blade formations I1 and I8. Because of the outwardly bowed shape-of the legs I0 and II, the points I5 and I6 close somewhat before the cutting edges of the blade formations I1 and I8 are brought together. With this arrangement, a loose thread may be grasped between the tweezer points-and stretched away use and resiliency of the legs of the tool is such that the cutting edges of the blade formations can be brought together to sever the excess fibres without such excessive manual pressure as will result in undue fatigue.

The invention may be embodied inroth'er specific forms without departing from the :spirit. or essential characteristics thereof. The present embodiment is, therefore, to be considered in all respects as illustrative and not -restrictive, the scope of the invention being'indicatedby the appended claims rather than by the foregoing description, and all changes which come 'within the meaning andrange of equivalency of 'the' claims are, therefore, intendedto be -embracedtherein. v What is claimed is: v f' 1. A bu'rling tool comprising a pair of fiat legs of resilient'material firmly secured together at: as

one end of said tool andha'ving' mutually opposed pointed endsat the other end of the tool, said legs being shaped to resiliently hold said pointed ends spaced apart, and cutting blade formations disposed onefon each leg adjacent S'O the pointed end thereof and extending along the corresponding edges of the-associated legs, said blade formations being disposed in mutually opposed relationship at the. same'side of the'tool and each havinga flat surfacein align- 35 4 ment with the corresponding edge of the associated leg, and said legs being longitudinally curved so that said pointed ends close before said blade formations. v

12. A burl-ing' tool comprising pair cif tweezers including a pair of coextensive legs of elongated rectangular cross sectional shape rigidly secured together at one end in face to face relationship "Sand pointed at the other end of the tool, and

a pair of mutually opposed and coextensive cutting blade formations provided one on each of said legs intermediate the length thereof and at the same side of said tool, each of said legs having a straight edgeportion at the location of the corresponding cutting blade formation, and each of said blade formations-having a fiat outer surface in alignment with the straight edge portion of the corresponding leg and a cutting edge along the edge of said flat surface proximate to the opposed blade formatiom said blades being located near the pointed ends-of s'aidl'egs, and said legs being longitudinally curved so that the pointed ends thereof closebefore'said blade formations.
