@vitnuozo to provide clearance JOHN IRWIN, OF PITTSBURG, PENNSYLVANIA.
` PLIERs.
Specification of `Letters Patent.
Patented June 8, 1909.
Application filed January 14, 1909. Serial No. 472,205.
To all whom it may concern: l
Be it known that I, JOHN IRWIN, a citizen of the United States of America, residing at Pittsburg, in the county of Allegheny and' Another object of this invention is to provide simple and durable pliers for performing the above work, the pliers being made for use in connection with wire of six to twelve gage.
With the above and other objects in view which will more readily appear as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts to be presently described and then claimed.
In the drawings, Figure 1 is a side elevation of a pair of pliers constructed in accordance with my invention, Fig. 2 is a plan of the same, Fig. 3 is a cross sectional view taken on the line Y-Y of Fig. 1, and Fig. 4 is a similar view taken on the line W-W of Fig. 1.
In the accompanying drawings, 1 and 2 designate the gripping jaws having rearwardly extending handles 4 and 3 respectively. The handle 3 adjacentto the jaw 1 is cut away, as at 5, to rovide clearance for the handle 4, which is a so cut away as at 6, for the handle 3. The handles 3 and 4 at the cut away portions are pivotally connected together by a pin 10.
The jaw 1 has the opposite. side faces thereof provided with vertical grooves 13 and slidably mounted in said grooves are cutting members 14 having rounded and beveled cutting edges 15.` The members 14 are slotted, as at 16, to receive stud bolts 17, carried by the jaw 1, and screwed upon said bolts are nuts 18 for holding the members 14 in adjusted position in the grooves 13. The extreme end of the jaw 1 is provided with a transverse cutting ridge 19 and the rear side of said ridge adjoining the jaw is formed with scraper webs 20, which also reinforce the ridge 19.
The jaw 2 directly beneath the ridge 19 and also in the path of the cutting members 14 is provided with transverse grooves or sockets 21 and 22, to receive a piece of wire to be operated upon by the pliers. In manipulating the pliers, the piece of wire to be operated upon can be placed in either of the grooves 21 or 22, but it is preferable to start with the groove 22. After a piece of wire has been located in this groove, the jaws are closed whereby the cutting members 14 will engage the insulation of the piece of wire, and by either rotating the wire or the pliers, the insulation of the wire can be provided with two circumferential cuts spaced according to the width of the jaw 1. i fter the insulation has been cut in this manner the wire can be transferred to the groove 21, the jaw closed, whereby the ridge 19 will slit the insulation between the circumferential cuts and permit of the section of insulation being removed. After the insulation has been stripped from the section of wire, the scraper webs 20 can be employed for cleansing the wire of all material that might adhere thereto between the circumferential cuts.
To limit the movement of the jaw 1 relative to the jaw 2 a screw 23 is mounted in the handle 4 of the jaw 1, said screw extending into an opening 24 provided therefor in the handle 3. On the screw 23 is adjustably mounted a nut 25. The position of this nut determines how far the jaws can be closed, and the object of using the same is to prevent the pliers from cutting into the wire.
The pliers are made of strong and durable material, and while in the drawings forming a part of this application there is illustrated a preferred embodiment of my invention, I would have it understood that the details of construction can be varied or changed as to the shape, proportion and manner of assemblage without departing from the spirit of the invention.
Having now described my invention what I claim as new, is
A 1pair of pliers, comprising jaws, rearward y extending handles carried by said jaws,` a pin pivotally connecting said han- IOO ' jus/cable cutting members carried by the same Jaw, and means for limiting the closing movement of said Jaws.
In testimony whereof I aHix my signature 1n JLhe piesence of two w1 tncsses.
JOHN IRWIN.
