Description
April 29, 1958 E. w. OLSON WIRE STRAIGHTENING PLIERS Filed Oct. 14, 1955 EEE o Ill-Isl MM INVENTOR. DGAR W. OLSON B is ar/fgg United statesmen.: o
WIRE STRAIGHTENING PLIERS Edgar W. Olson, Los Angeles, Calif. Application October 14, 1953, Serial No. 385,945` 4 Claims. (Cl. 81l15) This invention relates to a wire straightener and more particularly to a hand tool for straightening kinked and bent wire. s j
In certain'-industries, particularly' in the field of electronics, involved and elaborate wiring systems required straightening and forming of electrical conductors in order to provide a workmanlike appearance in the completed assembly and in order to conserve space within the wiring enclosure. It is common practice to secure small light weight electronic components by the electrical attachment of wire leads extending from and internally si connected to them. In straightening and forming these leads for attachment, care must be exercised to avoid damaging the internal connections.
The primary object of this invention is to facilitate the straightening of wire and electronic component wire leads without exerting excessive axial stress on a point of wire attachment.
Another object is to enable a service or repair man in the field to salvage a length of wire or to straighten it for forming for purposes of electrical connection or for the presentation of a workmanlike appearance.
The above and other objects may be attained by employing this invention which embodies among its features jaws mounted to move in arcuate paths toward a common axis, an anvil carried -by the jaws, and work supporting surfaces carried by the anvil and lying in the paths of movement of the jaws.
Other features inclu-de interleaved jaws, longitudinally spaced leaves carried by the anvil and extending outwardly therefrom in interleaved relation to the jaws, and work supporting surfaces on the leaves in the paths of movement of the jaws.
In the drawings:
Figure 1 is an end view of the tool with the jaws open,
Figure 2 is a view similar to Figure l showing the jaws closed about a wire,
Figure 3 is a side view partly in section of the tool shown in Figure l,
Figure 4 is a sectional view taken substantially on lthe line 4--4 of Figure l,
Figure 5 is a sectional view taken substantially on the line 5-5 of Figure 3,
Figure 6 is a view similar to Figure 5 showing the jaws closed about a wire, and
Figure 7 is a top plan view of the anvil.
Referring to the drawings in detail, `an anvil designated generally 10 comprises an elongated core 12 carrying longitudinally spaced outwardly and upwardly eX- tending leaves 14 and 16, which are provided with inwardly and downwardly curved anvil faces 18 and 20 respectively the edges of which intersect along a common axis to form a cradle in which the work W is received.
Extending through the leaves 14 on one side of the core 12 are aligned openings 22 and formed in the leaves 16 on the opposite side of the core 12 are aligned openings 24. The openings 22 receive a pivot pin 26 by means of which a jaw member designated generally 28 is pivotally connected to the anvil l0 and extending through the openings 24 in the leaves 16 is a pivot pin 30 by means of which the jaw member designated generally 32 is connected to the anvil 10.
The jaw member 28 is provided with `a handle 34 while the jaw member 32 is provided with a handle 36. AS will be readily understood upon reference to the drawing these handles 34 and 36 cross so that when they are advanced `toward one` another' their respective jaw mem bers will likewise advance toward work W lying in the cradle defined by the curved anvil faces 18 and 20. The jaw member 28 is composed of a row of longitudinally spaced leaves 38 which move in the spaces between the leaves 14 of the anvil 10 while the jaw member 32 is composed of a row of longitudinally spacedpleaves 40 which move in the spaces between `the leaves 16 of the anvil 10. The leaves 38 and the leaves 40 respectively are provided with curved surfaces 42 and 44 having radii corresponding to the radius of curvature of the anvil faces 18 and 20. By the interleaved structure above described, it will be evident that as the jaw member 28 is moved about its pivot 26 the curved surfaces 42 of the leaves 38 will move in arcuate paths which are intercepted by `the curved anvil surfaces 20 and as the jaw member 32 is moved about its pivot 30 the curved surfaces 44 will move in arcuate paths which are intercepted by the curved anvil surfaces 2t) `of the leaves 16 so that work W lying in the cradle defined by the curved anvil surfaces 18 and 20 will be squeezed between the jaw members 28 and the anvil surfaces 20 and the jaw member 32 and the anvil surfaces 18 when the jaw members are advanced `toward the anvil surfaces. Thus any bends or kinks in the work will be removed.
In the preferred for-m of the invention the jaw members 28 `and 32 are respectively provided with slots 46 and 48 respectively which intersect along an axis which lies die rectly below the core 12 of the anvil 10, and extending through said slots is a guide pin which is received adjacent its opposite ends in slots 52 `of stabilizing plates 54 which are held against opposite ends of the anvil 10 by the pivot pins 26 and 30. It will thus be seen that the cooperative relationship between the anvil 10 and the jaw members 28 and 32 will be preserved.
In use work W is placed in the cradle defined by the anvil surfaces 18 and 20 with the jaw members open substantially as shown in Figure 1. In this position of the parts, the stabilizing pin 50 will be at its highest position in the slots 52 in the stabilizing end plates 54. As the handles 34 and 36 are advanced toward one another, the jaw members 28 and 32 will move to advance the curved surfaces 42 and 44 toward the curved anvil faces 20 and 18 respectively so as to squeeze the work W between the jaw members and the anvil. kinks .and bends may be removed from the work.
While in the foregoing there has been shown and described the preferred embodiment of this invention it is to -be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.
