UNITED STATES RAYMOND A. WILLIAMS, OF PITTSFIELD, MASSACHUSETTS.
INSULATED-VIRE STRIPPING AND SCRAPING DEVICE.
AppIication led December 11, 1924.
To all whom t may conce/rfa.-
Be it known that I, RAYMOND A. WILLIAMS, a citizen of the United States, residing at Pittsfield, in the county of Berk- ,5 shire and the State of Massachusetts, have invented a certain new and useful Improvement in an Insulated-1N ire Stripping and Scraping Device, of which the following is a specification.
My invention relates to improvements in that class of devices adapted for stripping insulation from insulated wire, and also for scraping the wire after the insulation has been removed.
Another object of my device is to provide means whereby the length of the wire to be stripped may be regulated to any desired length. This obj ect I accomplish by providing a tubular device with an internal regu- '2G lating guide.
Referring to 'the accompanying drawing, in which like numerals indicate like parts, Figure 1 is a plan view showing the combined stripping aws and the wire scraper. Figure 2 is a front elevation view in partsection showing the details of construction more clearly in accordance with my invention. Figure 3 is a side elevation view of the device.
In the drawing, the numerals 1 and 2 designate the pivoted members of the tool which are connected by means of the pivot pin 16. The upper part of the tool is provided with stripping jaws 3 and 4, and the jaws are secured to the pivoted members by means of screws 5. is
The stripping jaw a serrated on the outer end and operates in conjunction with the wire scraper 18.
A U-shaped wire scraper 18 is pivoted to one of the pivoted members of the tool by means of a pin 19, and is held in contact with the serrated stripping jaw 3 by means of springs 21, which are secured to one of the pivoted members of the tool and tothe wire scraper by means of-the pins 20. It will be seen by referring to the drawing that the wire scraper is serrated, and by means of the springs 21 the opening 22 between the serrated edges of the stripping jaw 3 and tha wire scraper 18 may be regulated to take various sizes of wire.
A tubular member 6 passes thru the pivot pin 16 and is secured thereto, and the said tubular member is provided with notches 7 on one side. A tubular member 23 is placed over the tubular member 7 and the said Serial No. 755,300.
tubular member 23 is provided with a recess 24 on the side adjacent to the notched tubular member 6. A spring clip 12 is attached to the tubular member 23, and the lower end of the spring clip passes thru the recess 24 and is held in contact with the vnotched tubular member 7 as indicated at 13, by means of the resiliency of the clip. The tubular member 23 is free to slide up and down over the tubular member 6. The tubular member 6 is provided with a recess 9, to provide means for regulating the guide 8 to pass up and down within the tube. The guide 8 is provided with an extension rod 10 which rod is held in contact with the tubular member 23 by means of a pin 11.
The insulated wire 17 is placed between the stripping jaws 3 and 4 and into the tubular member 6 and lin contact with the guide 8. By operating the guide 8, by means of the vtubular member 23v and the spring clip 12, which clip engages in the notches 7, any desired length of insulated wire may be stripped by regulating the guide 8 within the tubular member 6 to the desired length required. By means of the springs 21 the serrated edges of the stripping jaw and the wire scraper are held in close contact, thereby assuring the proper tension between the serrated edges of the stripping jaw and the wire scraper, to regulate the opening 22 to conform to various sizes of wire to be scraped.
The lower end of one of the pivoted members of the tool is provided with an eccentric disk 14, which disk is pivoted to the tool member 1 by means of a pin 15. The eccentric disk is so designed, that by placing one of the fiat surfaces of the disk lon the tool member adjacent, the stripping jaws are regulated to cut thru the insulation on the wire without injuring the wire. Various sizes of wire may be stripped by regulating the fiat surfaces on the eccentric disk in an eccentrical manner from the pivot pin 15.
It is obvious that changes might be made in various more or less substantially different forms without departure from the spiritof my invention, therefore I do not wish to limit myself to the exact construction.
I-Iaving thus described my invention, what I claim is l 1. The combination with a pivoted tool member of the class described having operating handles and comprising stripping jaws, means to secure said jaws to the tool membersj a tubular member :tor regulating the length of the cable to be stripped, i stop within seid tubular member, and en extension rod affixed to said Stop, said tubular 'member provided with :i plurality of notches on the outer side, a spring clip slidably ifixed to the said tubular member and cooper'- ating with the notches; thereon, and im eccentric cam rotatably connected to the tool member to provide means to regulate the Size of the `wire to he stripped.
2. The coiiibinzition with e pi'voted tool member 'of 'the class deseriiied comprising` stripping jaws, means to secure said jaws to the tool members, a tubular memiiier for regulating the length of cable to be stripijicd, said tubular member provided with a longitudinal slot9 and the outer side of Seid tubular member provided with a plurality oi notches, n stop YWithin said 'tubular member, an extension rod eilixed to seid stop, means to operate seid stop7 a tui'iiilar n'iember provided 'with u spring clip, said clip to eooperate with the notched tubular member, and an eccentric cam rotatably connected to the tool member ro provide means to regie hiie the size voit' the wire te be stripped.
In testimon)Y whereof l set my hated und Signature. p
