WIRE WORKING TOOL I Mason l oshee; KissimmeeQFl'a. Application September 23,- 1937, Serial No. 165.410 501m (or 146-417) This invention relates to improvements in wire be bent as indicated at 26, Fig. 2.

Thus two full rotations of designated it, of which the wire bending arm H, the tool will result in the formation of a coil of the hooking arm 12, and the tubular arm portion two convolutions.

other and to the sides or walls of the notch ii. A further operation permitted by the coiling In the operation of the tool as a bender; the tool arm of the tool is that of coiling a wire directly on is placed so that its notch 15 receives the wire to a male loop, such as indicated at 32. To eifect 55 this operation, the loop 32 is projected into the tubular shank 22, the inner diameter of the shank being such as to permit this insertion with suitable clearance. The lateral movement permitted the mandrel also aids in the insertion and compensates for any irregularities in the width of the loop. With the loop so inserted in the mandrel as indicated at 32, Fig. 3, and with the wire to be coiled thereabout properly seated in the offset notch 21, turning movement of the tool about the axis of shank 22 operates to coil the wire 30 directly on the loop 32.

Referring now to the tool arm l2, the outer end thereof is tapered and narrowed as at 35 to provide a pointed tang end. In operating the tool as a hooker or sealer, the tang end is projected through the end of a male fastener loop which has been threaded through or otherwise cooperated with the female loop or coil. Thereupon the pointed end of the tang is anchored against the adjacent surface of the front section of the container, and the arm 12 operated as a lever to cause the nose or projecting end of the male loop to be hooked over the related female fastener element. By exerting the proper degree of hooking or bending pressure on the arm, the bent-over end of the male loop may be brought into close proximity with the front face of the container.

The tool as described above may be constructed at a low cost and by actual experience has been found to perform in efficient manner the operations for which intended.

As many changes could be made in carrying out the above construction without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

I claim:

1. A wire-working tool including a cross portion and a tubular shank portion, a mandrel carried by the shank portion and extending beyond the end thereof, the end face of the shank portion being inclined and having an offset notch formed in the long side of the shank portion, the bottom of the notch being in substantial alignment with the opposite, short side of the shank portion, the notch being adapted to receive the wire for coiling on the mandrel.

2. A wire-working tool including a cross portion and a tubular shank portion, a mandrel loosely carried by the shank and extending beyond the end thereof, the end face of the shank portion being inclined and having an offset notch formed in the long side of the shank portion, the bottom of the notch being in substantial alignment with the opposite, short side of the shank portion, a defining side of the notch being extended to form a wire retaining hook, the notch being adapted to receive a wire for coiling on the mandrel.

3. A wire working tool including a tubular shank portion, a mandrel carried by the shank portion and extending beyond the working end thereof, the mandrel being of lesser diameter than the interior diameter of the shank portion, and means extending from the working end of the shank portionadapted to engage against the free end portion of a wire disposed transversely of the mandrel and bearing thereagainst, said means being operative upon rotation of the tool about its axis to coil progressively the free end of the wire on the mandrel.

4. A wire working tool including a handle porton, 2. depending tubular shank portion, and a mandrel operatively disposed within the shank portion and extending beyond the working end thereof, the interior diameter of the shank portion being sufiicient to receive a generally parallel-sided loop of wire, and the working end of the shank portion being provided with means adapted to engage a length of wire disposed transversely of the mandrel and bearing thereagainst, said means being operative upon rotation of the tool about its axis to coil progressively the length of wire on the mandrel and about a loop received within the tubular shank portion.

5. A wire working tool including a handle portion, a depending tubular shank portion, and a mandrel loosely carried by the shank portion and extending beyond the working end thereof, the interior diameter of the shank portion being sufficient to receive a generally parallel-sided loop of wire, and the diameter of the mandrel being substantially less than the inner diameter of the shank portion, and means extending from the working end of the shank portion adapted to engage against a length of wire disposed transversely of the mandrel and bearing thereagainst, said means being operative upon rotation of the tool about its axis to coil progressively the length of wire on the mandrel and about a loop received in the tubular shank portion.
