WIRE FORMING IMPLEMENT Filed Oct. 12, 1965 FIG. 6 4g INVENTOR 1 7 EUGENE GAWURA ATTORNEY United States Patent 3,357,460 WIRE FORMING IMPLEMENT Eugene Gawura, 6927 Coleman, Dearborn, Mich. 48126 Filed Oct. 12, 1965, Ser. No. 495,282 2 Claims. (Cl. 140106) ABSTRACT OF THE DISCLOSURE A wire forming hand tool comprising a pair of pivoted jaw members carrying mating dies which shape a terminal offset in straight end sections of wire when the jaw members are squeezed together.
This invention relates to wire forming implements generally, and more particularly to a hand tool for placing a terminal off-set in a section of wire.
Wire forming operations are usually performed by machine dies, especially when heavier gauges of steel wire are involved. This method is generally less costly, much more accurate, and far better adapted for modern production techniques. However, in servicing many production items, such as power lawn mowers, it is sometimes necessary to replace components which are customarily not stocked by repair shops or parts depots. It is therefore necessary either to obtain parts from the manufacturer or attempt to duplicate the component by the use of shop tools and equipment which are customarily available.
The former practice is usually time consumming, and the latter alternative is generally somewhat involved and consequently quite expensive. Since neither practice represents a completely satisfactory solution to the problem, the applicants primary objective in the present invention is to provide a special purpose hand tool for use in mower repair shops to form the characteristic terminal offset required on most power mower throttle wires.
Another object of the invention is the provision of a hand tool of the type previously described, which is extremely effective, and very simple to use and operate.
A further object of the invention is to provide a hand tool of the type previously described, which is strongly constructed, and relatively inexpensive to produce.
Other features and advantages of the invention will become apparent after thorough consideration of a detailed description of the same composed with reference to the drawings constituting a part of this application, and in which:
FIGURE 1 is a side elevation view of the applicants hand tool, showing the pivoted jaw members in an open position, and the lateral slot in the upper die.
FIGURE 2 is an elevation view taken substantially on plane 22 in FIGURE 1, showing the cavity in the upper die, and the characteristic shape of the lower die or punch.
FIGURE 3 is an elevation view similar to FIGURE 2, showing the forming dies in a closed position on a section of wire.
FIGURE 4 is an elevation fragmentary view similar to FIGURE 1, disclosing a modification of the applicants invention, and showing the aligned lateral slots in the forming dies.
FIGURE 5 is a side elevation view similar to FIGURE 4, showing the forming dies in a closed position on a section of wire.
FIGURE 6 is an elevation view taken substantially on plane 6-6 in FIGURE 4, showing the depth of the aligned lateral slots in the forming dies.
FIGURE 7 is an elevation view showing a section of wire having a terminal offset formed by the applicants hand tool.
For a more detailed description of the invention reference is made to the drawings in which numerals 10 and 12 designate respectively upper and lower jaw members pivotally connected together by a rivet 14. A hollow gripping handle 16 is formed integral with the upper jaw member 10. A downwardly disposed gripping handle 18, having a U-shaped cross section, is pivotally connected to the lower jaw member 12 by a rivet 20.
A fulcrum bar 22 is pivotally connected on one end to the gripping handle 18 by a rivet 24, and slidably positioned in the other handle 16. A knurled head adjusting screw 26 is threadably engaged in the hollow handle 16, and turned into contact with the free end of the fulcrum bar 22. A coil spring 28 is connected at one end on a hook 30 in the hollow gripping handle 16, and at the other end to the lower jaw member 12 intermediate the two rivets 14 and 20.
A pair of dies 32 and 34 are fixed on the upper and lower jaw members 10 and 12 respectively. The die 32 or matrix has therein a cavity 36 with one of the defining side walls 38 outwardly disposed. A lateral slot 40, in the upper die 32, communicates with the cavity 36 therein provided. The lower die 34 or punch has a tapered side 42 the angle of which matches that on the outwardly disposed wall 38 in the upper die 32.
An upwardly faced concave seat 44 is provided in the lower jaw member 12 for reception of the upper die when the jaws are in the closed position shown by FIGURE 3.
The modification disclosed in FIGURES 4, 5 and 6 differs from the embodiment of FIGURES 1 through 3, in that the wire stock is fed into the jaw members 10 and 12 in a longitudinal rather than a transverse manner. In this modification, two dies 46 and 48 are mounted on the upper and lower jaw members 10 and 12 respectively, in an offset relationship. Laterally aligned longitudinal slots 50 and 52 are provided in the two dies 46 and 48 respectively.
This completes a description of the structural details of the invention herein disclosed; however, to insure a fuller comprehension of the subject matter, a discussion is immediately hereinafter directed to the manner in which the device is used to accomplish its intended function, and achieve the objectives set forth in the introductory portion of this specification. Since both embodiments of the applicants invention function in substantially the same manner, the discussion of use will be limited to the disclosure in FIGURES 1, 2 and 3.
In use, a section of wire 54 is inserted into the lateral slot 40 of the die 32, and positioned as shown in FIGURE 2 of the drawings. The handles 16 and 18 are then squeezed so as to close the jaw members 10 and 12, and bring the dies 32 and 34 into the mating position shown in FIGURE 3. In moving to this position, the die 34 forces the wire 54 into the cavity 36 of the die 32, thereby providing the terminal offset shown in FIGURES 3 and 7.
Based upon the foregoing discussion, the applicant is of the opinion that his invention has fulfilled a long-felt need in the field of hand tools, and that he has accordingly made a valuable contribution to the related art. However, while the invention was described with reference to the structural details of a limited number of embodiments, it will be appreciated by those familiar with the art, that the principles involved are susceptible of numerous other practical adaptations.
Therefore, I claim as new and desire to secure by Letters Patent:
1. A Wire forming implement comprising twopivoted jaw members having an open and a closed position, means for manipulating the jaw members, a die on one of the jaw members having therein a cavity one side wall of which is outwardly disposed, a transverse slot in the die for receiving and positioning an end section of wire across the cavity, and a die on the other jaw member shaped to fit into the cavity of the first mentioned die when the jaw members are moved to a closed position, such second mentioned die member forcing the end of the wire to slide along the outwardly disposed side Wall to the bottom of the cavity thereby forming a terminal offset in the wire.
2. A wire forming implement comprising two pivoted jaw members having an open and a closed position, means for manipulating the jaw members, a die on one of the jaw members having in one side a longitudinal slot therethrough for receiving an end section of wire, and a die on the other jaw member disposed laterally from the first mentioned die and having a slot in one side aligned with the slot in the first mentioned die when the jaws are in an open position, such slot in the second mentioned die receiving and positioning the wire so that when the jaw members are moved toa closed position a terminal offset is formed in the wire.
