1 Claim.
My invention relates to improvements in stripping implements for removing insulation from wire, the principal object in view being to provide an inexpensive, easily handled implement for stripping insulation from wires of different sizes within a wide range of gauges and without cutting the wire.
Another object is to provide a device of the character and for the purpose set forth which will bite into or cut the insulation substantially clear around the wire, through the insulation and will then yieldingly strip the wire so that the latter will not be cut into or otherwise weakened.
Other and subordinate objects are also comprehended by my invention, all of which, together with the precise nature of my improvements, will be readily understood when the succeeding description and claim are read with reference to the drawing accompanying and forming part of this specification.
In said drawing:
Figure 1 is a View in side elevation of my improved implement in its preferred embodiment,
Figure 2 is a view in front end elevation and drawn to an enlarged scale, and
Figure 3 is a view in longitudinal section taken on the line 33 of Figure 1 and drawn to an enlarged scale.
Reference being had to the drawing by numerals, my improved implement, in its preferred embodiment, has the form, with exceptions presently noted, of a pair of pliers, in that it embodies a pair of bowed hand grip bars I pivoted together, as at 2, in crossed relation for movement of the hand grip bars toward and from each other to correspondingly move a pair of flat sided, elongated jaws 3, 4, extending forwardly from said bars I, respectively, in front of the pivot 2 and in a common plane with said bars.
The jaw 3 is integral with one of the bars I and comprises a straight inner edge portion 5. In the rear of said edge portion 5, a longitudinally extending, straight edged, wire cutting lug 6 is suitably incorporated with the jaw 3 to project inwardly from said edge portion for a suitable distance.
The jaw 4 is provided with a bifurcated rear end forming a pair of laterally spaced ears I straddling a forwardly extending lug 8 on the other bar I, to which lug said ears are pivoted, as at 9, so that the jaw 4 is hinged to the lug for swinging thereon in the plane of the jaw 3. The lug 8 is provided with a wire cutting lug 6 similar to lug 6 and opposed to the latter for cooperation therewith under movement of the jaws 3 and 4 toward each other. The lug 8 coacts with the inner end of the furcation of the jaw 4 to limit swinging of said jaw inwardly.
A heavy bar-like spring I0 is secured, as by screws I I, to a flat outer face l2 on the lug 8 with its major portion extending along the outer edge of the jaw 4 and bearing against the same, whereby said jaw 4 is tensioned against outward swinging on its pivot 9 away from the jaw 3.
A pair of opposed male and female stripping teeth I 3, l4 extend inwardly from the ends of the jaws 4, 3, respectively, at right angles thereto. The male tooth I3 i provided with a triangular, flat, beveled end l5 inclined forwardly and outwardly to provide on the tooth a transversely straight rear cutting edge It, and with side edges converging toward said end l5 and beveled transversely to provide converging side cutting edges IE on the tooth. The female tooth I4 is provided with a center socket open at its front and rear and having side walls I8 converging rearwardly and also inwardly of the socket to provide rear side cutting edges l9 forming a V-shape cutting notch.
As will be understood, the male tooth I 3 is designed to be entered into the female tooth 14 under closing of the jaws 3, 4 with the cutting edge l6 interposed between the cutting edges l9 and the cutting edges l5 coacting with said cutting edges l9. In the described coacting relation of the cutting edges [6, l9 and I5, the insulation on a wire trained through the socket of the female tooth l4 will be cut substantially completely around the wire and the end l5 of the male tooth [3 together with the bottom of the socket of the female tooth M will flare outwardly to clear the wire in front thereof so as to facilitate effecting a clean cut. Preferably. the cutting edges I5 and 19 are formed on a degree angle although other angular arrangement may be resorted to. Because of the V shape of the cutting edges l9, various sizes of wires may be trained through the socket of the female tooth M. The spring I0 is designed to provide sufiicient tension against the jaw 4 for cutting by the teeth l3, I4 into and through insulation and to yield when the wire is contacted so that the wire will not be cut or nicked and thereby weakened.
The foregoing will, it is believed, suffice to impart a clear understanding of my invention without further explanation.
Manifestly, the invention, as described, is susceptible of modification without departing from the inventive concept, and right is herein reserved to such modifications as fall within the scope of the subjoined claim.
What I claim is:
An implement of the class described comprising a pair of hand grip bars pivoted together in crossed relation for opening and closing movement, and a pair of opposed forwardly extending jaws on said arms, respectively, operative toward and from each other under opening and closing of said bars, respectively, said jaws: embodying an intumed end tooth,.vrespectively, one of said teeth comprising a socket having open front and
