TOOL FOR WIRE.
Speeication lof Letters Patent.
Patented MaySO, 1911.
Application filed October 24, 1910. Serial No. 588,600.
To allwhom 'it may concern:
Be 1t known that we, CARL K. BERG and OLE K. BERG, citizens of the United States,
residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Tools for Wire, of which the following is a specification.
This invention relates more particularly to tools or devices for fastening the ends of Wire, taking up slack in a loose piece of wire, such for instance as a band, and for winding up the free end of a piece of wire around a pin or mandrel, which pin or mandrel is left in engagement with the wire to form a fastening for the end of the wire.
In attempting to manipulate wire, in order to take up the slack in a loose wire or to draw the ends of a wire tightly together, we have discovered that if the wire is drawn or twisted closely upon itself, it will break very easily and therefore cannot be drawn as tight as is frequently desirable. In order to overcome this difficulty, we have discovered that if the wire, instead of being bent upon itself or upon the end of the opl posite wire, when the joint is being made,
is bent around a separate pin or mandrel so as to form spirals around an open center instead of upon the wire itself, the wire may be drawn very tight without breaking and will remain tight even after the pin or mandrel is withdrawn, as the closely wound coils will retain their shape without allowing the wire to slacken. It will be noted that this result may be obtained by tools of slightly varying character but all having the same genera-l characteristics, and we have shown in the accompanying drawings several embodiments of our invention.
In these drawings-Fi re 1 is a side view of a tool used for ta :ing up the slack in a loose wire or band; Fig. 2 is a top plan view of the tool shown in Fig. 1, also indicating the method of twisting the wire;
Fig. 3 is a bottom plan view of the tool shown in Fig. 1; Fig. 4: is an end view of the same; Fig. 5 is a plan view of the loop and coil formed in the wire; Fig. 6 is a side view of the same; Fig. 7 is a side view of a modified form of tool in which the pin or mandrel is of a temporary or removable character; Fig. 8 is an end view of the same, showing the wire as it is started to be coiled; Fig. 9 is a detail view showing the wire coiled on the removable pin or mandrel;
Fig. l() is a side view of another form of tool used for fastening the free ends of a wire together; Fig. 11 is an end view of the same, showing the ends of the wire in position to be acted upon; and Fig. 12 is a detail showing the joint or connection made between thc ends of the wire.
As indicated in these drawings, 13 represents a tool or wire manipulating device having a shank 14 suitably shaped3 for engagement with an ordinary brace for turning the same. The head 15 of the tool is preferablyV flattened as indicated, and is provided at its end with a short projection 16 and a longer projection 17, forming therebetween a transverse groove 18 for receiving the wire 19 which is to be tightened. The inner faces of one or both of the projections 16 and 17 are preferably slightly undercut, as indicated at 20, so that when the tool is placed over the wire and turned until it binds the wire, the wire will fit in these grooves and will be held firmly in position and, if desired, may be pulled in a direction transversely to its length. The projection 17 is rounded to form a mandrel or pin around which the wire is to be bent to form a double coil. The outer surface of the projection 16 is somewhat slanted or tapered, as indicated at 21, and the outer edge of the head on the opposite side adjacent to the base of the projection 17 is also slanted or beveled as indicated at 22, this slanting or beveling being provided for the purpose of properly turning or directing the wire in order to start the coil formation.
The tool is operated by pressing the head against the wire until the wire is seated or pressed into engagement with the groove 18, and then turning the tool, as by means of a brace or other suitable means, in the direction Vindicated by the-arrow in Fig. 4. A portion of the wire on one side of the tool will be bent around the projection 16, thereby forming a loop, such as indicated at 23 in Figs. 5 and 6. The portion of the wire on the other side of the tool will be bent around the mandrel or projection 17, thereby starting the double coil 241, as indicated in Figs. 5 and 6. It will be noted that, as the projection 16 is comparatively short, that is about as long as the thickness of the wire, after the loop 23 has been formed around the same and the turning of the tool is continued, the end of the wire which has passed around this projection will be thrown into engagement with the projection 17, and as the turning of the tool is continued, both portions of the wire will continue to be drawn up and wound around this projection or mandrel, thereby forming a double coil. The mandrel is preferably somewhat tapered, so that it may be readily withdrawn after the wire is tightened, and may be made of any desired length, so that more or less slack may be taken up by forming longer or shorter coils. As above suggested, the forming of the double coil around the mandrel or projection enables the wire to be drawn exceedingly tight without danger of breaking the same, and then when the tool is removed, this coil will retain its shape and hold the wire in its tightened condition.
In the modified form of construction shown in Fig.7, the tool 25 is provided at one end with a hole or socket 26 for receiving a removable pin or mandrel 27. Adjacent to this socket is a projection 28, which is slightly curved or beveled on its outer side, as indicated at 29, for properly turning 4the wire onto `the pin for forming the coil. This tool may be turned in any desired manner, as is the case with the one above described, and for this purpose we have indicated a handle 30, which may be used instead of a brace. This particular form of tool is especially adapted for drawing up the free end of a wire and providing means for holding the free end after it has been tightened. An illustration of such use is in the making of boxes, where the end of the wire may be allowed to project through .the side of the boX, and when this end is tightened and provided with a pin 27, it will form a secure fastening for the wire. l/Vhen this tool isl to be used, the pin 27, which may be formed of a short piece of wire, is inserted in the hole 26 and then the end of the wire which is to be tightened is placed in the opening between the pin and the lug or projection 28, and the tool is then turned. This will start to bend the end of the wire, as indicated in Fig. 8, and when the tool passes around until the outer side of the projection 28 comes in contact with the wire, this curved or beveled side will direct the wire forwardly so that it will slip in position adjacent to the first turn around the pin, and a continued turning of the tool will cause the formation of a tight coil 31 around the Copies otvths patent may be obtained for ve cents each, by addressing the Commissioner of Patents.
A further modified form of our improved wire manipulating devices is shownl in Fig. 10, in which the tool 32 is provided with a head 33 having a central forwardly projecting pin or mandrel 34; and side projections 35 and 36, thereby forming grooves 37 at either side of the central pin. The projections 35 and 36 are beveled or tapered as shown so as to direct the wire to start the formation of a double coil 38, as indicated in Fig. l2. This tool is used for winding together the free ends of wires, as indicated at 39 and 40, and simultaneously tightening the wire, as in placing a band around a bOX or the like. These ends are placed inthe slots or grooves 37 and the tool turned in the direction indicated, which will cause the ends to be wound around the mandrel 34, thereby forming a tight double coil, asindicated at 38. When the coil is completed and the wire tightened, the tool is withdrawn, ready for t-he neXt operation.
Having thus described our invention, which we do not wish to limit to the particular forms of construction herein shown, eX-
cept as set forth in the appended claims, what we claim and desire to secure by Letters Patent is:
l. A tool of the character set forth, comprising a head having a forwardly projecting mandrel, and a relatively short projection or lug adjacent to said mandrel, forming a slot for receiving the wire, the sides of said slot being undercut, whereby the wire will be held more iirmly in the slot when the tool is turned.
2. In a device of the character set fort-h,
the combination of a head having a forwardly projecting mandrel around which the wire is to be coiled, and a rojection adjacent to said mandrel for coi ing the wire around the mandrel when the tool is turned, the sides of said tool adjacent to the projection and the base of the mandrel being beveled to give a forward pitch to the wire.
