说明书全文 | The present invention relates to methods and apparatus for use in the bailing of compressed recyclable articles, and, more particularly, to methods and apparatus for twisting wire used to contain such compressed articles in compact bails. In the past, various tools and apparatus have been utilized to twist together ends of lengths of wire in the bailing of objects and materials of various sizes and shapes. Such tools and apparatus have varied from relatively simple wrenches and pliers of different sizes and shapes to more elaborate combinations including screws, clamps, levers and gears. Prior simple tools have been inefficient in operation requiring the exertion of considerable physical energy. The more elaborate tools have been complex and expensive. The object of the present invention is to provide a simple inexpensive wire twisting tool that easily and efficiently twists the ends of wires into interconnecting loops ideally suited to the bailing of compressed recyclable articles. Basically, the present invention comprises a method and apparatus for twisting wire using an axially elongated hand-holdable one-piece tool having an outer axially extending slot and an inner axially extending hole in a forward end thereof. Basically, the method comprises the steps of (1) bending one end of a longitudinally extending length of wire to form a generally U-shaped end portion having a long leg comprising the length of wire and a relatively short bent leg portion, (2) axially securing the U-shaped end portion, (3) inserting an end of the bend portion of wire into the hole in the forward end of the tool and laying the long leg of wire in the open outer slot in the tool and (4) turning the tool on a longitudinal axis thereof while the tool moves axially rearward relative to the long leg of wire to form a loop in a forward end of the length of wire and to twist the bent leg portion over and rearward along and around the long leg of wire adjacent the loop. As depicted generally in the drawings, the present invention comprises a method and apparatus for twisting wire including the steps illustrated in As stated, the apparatus of the present invention comprises a tool 10 as represented in Basically, the tool 10 comprises an axially extending and elongated hand-holdable tool body 14 having an axially extending hole 16 in a forward end 18 thereof for receiving an end portion 20 of a length of wire 22. The tool body 14 may be formed of any suitable light-weight metallic material and may be of a hexagonal cross-section for easy gripping by the wrench included in the apparatus of the present invention. Also, the hole 16 preferably extends the length of the tool body 14 to allow the end portion 20 to initially extend beyond a rear end 30 of the tool body 14. In addition, the tool body 14 includes an axially extending open outer slot 24 for receiving a portion 26 of the length of wire 22 adjacent the end portion 20 extending into the hole 16 in the forward end 18 of the tool. Preferably, the slot 24 has inwardly extending upper edge portions 24a and 24b. The edge portions 24a and 24b vertically limit movement of the wire portion 26 within the slot 24 while opposing sides 24c and 24d of the slot below the edge portions limit lateral movement of the wire portion 26 within the slot during a turning the tool 10 on a longitudinal axis 28 thereof by hand reciprocation of the wrench included in the apparatus of the present invention. In these regards, the wrench preferably comprises the ratchet wrench 32 of conventional design. An annular ratchet head portion 34 of the wrench 32 is dimensioned to axially receive the tool body 14 while a radially extending open ended slot 36 in the head portion 34 is dimensioned to allow passage of the wire portion 26 into the annular head portion during the mounting of the wrench on the tool body. As stated, the method of the present invention using the apparatus of the present invention is depicted by the steps illustrated in While a particular embodiments of the method and apparatus of the present invention has been illustrated and described in detail above, it is appreciated the changes and modifications may be made in the illustrated embodiments without departing from the spirit of the invention. For example, the one-piece tool 10 is constructed such that if a forward end of the tool body 14 or forward ends of the axial hole or outer slot 24 should become worn with use of the tool 10, the tool 10 may be reversed so that the wire end portions 20 and 26 may be introduced into the original rear ends of the hole 16 and slot 24 without altering the steps comprising the method of the present invention. Accordingly, the scope of present invention is to be limited only by the terms of the following claims. |
