WIRE OR ROD CUTTER.

Specification of Letters Patent.

Patented Oct. 1'7, 1905.

Application filed January 15, 1904. Serial No. 189,073.

To aZZ whom, it may. concern:

Be it known that I, THOMAS D. MILLEA, a citizen of the United States of America, residing at Springfield, in the county of Hampden and Commonwealth of Massachusetts,liave invented a new and useful Wire or Rod Cutter, (the same being an improvement on the implement set forth in United States Letters Patent No. 720,168, issued to me February 10, 1903,) of which the following isaspecification.

My invention relates to improvements in devices designed to cut wire and the like; and it consists of the kind of wrench described in the above-mentioned patent provided with a cutting member and having a suitably-positioned wire-receiving notch, all as hereinafter more fully explained; and the objects of my invention are, first, to provide such a wrench with a strong and durable wire-cutter; second, to afford convenient means for sharpening the wire-cutting plate or blade, and, third, to provide a tool of this character which is comparatively inexpensive, easy to operate, and compact and serviceable. I attain these objects by the means illustrated in the accompanying drawings, in which- Figure 1 is a side view of my combinationtool, showing the new features, a portion of the fixed jaw being broken away to illustrate the manner in which wire-stretching spurs may be attached thereto; Fig. 2, an edge view of the same, only one of the aforesaid spurs being seen; and Fig. 3 an opposite side view, the spurs being omitted.

Similar letters refer to similar parts throughout the several views. 7

In the drawings the jaws of the tool are shown closed; but it will be understood that they may be opened like any ordinary wrench of this kind.

I will first proceed to describe briefly the parts of the device which enter into the invention already patented, as noted above. A fixed or immovable jaw a is mounted on a fixed or immovable shank Z), the lower end of which latter forms a skeleton handle 7). A movable jaw c is mounted below the jaw a on the shank I) and has a movable shank olscrewthreaded at d'. The projecting ends of the jaw 0 or lateral projections from the shank d are thick enough to embrace the edges of the shank 7), upon which said jaw slides, and a an opening in the base of the handle I), re ceives the screw-threaded part d. The sleeve g is held against longitudinal movement by a flange it inside of the handle 6, which enters a groove 21 in said sleeve. A thumb-nut j on the outer end of the sleeve 9 facilitates rotating the latter. Projecting parts la and 79 on one side of the jaws a and-o, respectively, form a head-end wrench or hand-vise. A pipewrench is provided by serrating the lower edge of the jaw a at one end,'as shown at Z, and locating a serrated grip m on the corresponding upper edge of the jaw 0, such grip being held in place by a screw f, which may also assist the screwsf in securing the plate 6. A pipe-cutter n is suitably mounted in a recess in the jaw c and a pipe-hole 0 made in the shank b. The cutter n extends into the head-end-wrench notch in the jaw 0, and the hole 0 may open into the head-end-wrench notch in the jaw a.

By converting the plate 6 into a blade with a cutting edge and notching or perforating one edge of the shank b at some convenient point below said cutting edge when the plate 6 is in a position which will enable it to be actuated downward until the cutting edge is below the base of the notch or perforation I have produced a servicable wire-cutter. The aforesaid cutting edge is represented at e and a notch at p. The cutting edge eand the top and bottom edges of the notch 2 should be inclined out of the horizontal in order to produce the best results, since the wire is thus subjected to two sharp edges during the process of cuttingthat is, the edge of the plate 6 next to the shank 5 and the lower front edge of the notch pwhile the upper rear edge of said notch, which is also sharp, assists in holding said wire during such process.

The above-described wire-cutter forms a part of the invention set forth in British Patent No. 2,459 of February 2, 1903; French Patent No. 329,016, of February 2, 1903; Belgian Patent No. 168,211, also of February 2, 1903, and Canadian Patent No. 80,789, of May 5, 1903.

In operation the shank (Z is actuated upward through the medium of the thumb-nut y' until the cutting edge e of the plate or blade 6 is above the notch 19. Then the wire to be operated upon is placed in said notch and said thumb-nut turned in the opposite direction to actuate said blade downward until said cut, ting edge has severed the wire.

If the cutting edge 6 becomes dull, the blade 6 can be taken off by removing the screws f and f, when said cutting edge may be easily sharpened, after which said blade is replaced. This is an important advantage and one which is often absent from ordinary wire-cutters.

From the foregoing it will be observed that in the present construction the plate or blade 6 serves the double purpose of assisting in uniting the movable and immovable parts of the tool and uniting them in such a manner as to render them easily detachable and of constituting a cutter which is detachable.

A wire-stretcher which may be combined with the other features of the Wrench comprises a plurality of spurs projecting from the upper or outer longitudinal edge of the fixed jaw, such spurs being either integral with or permanently attached to said jaw or removably connected therewith, the latter arrangement being preferred. The edge portion of the fixed jaw, from which the spurs extend, should be rounded or curved longitudinally or be made up of different planes for reasons which will be obvious upon a full understanding of the operation of the stretcher. In the present instance I show three spurs q, screw-threaded at their bases and having their sides flattened, and I provide screw-threaded openings 1" in the upper edge of the jaw a to receive the screw-threaded portions of said spurs. By flattening the sides of the spurs q above the screw-threaded portions convenient means is afforded for applying a wrench to the same for the purpose of seating said spurs in the jaw or detaching them therefrom. By making the spurs detachable the tool is rendered more convenient when it is not desired to use the same for stretching wire, because they would then be more or less in the way if not removed. Although three spurs (1 have been shown, it is clear that more or less than that number may be employed. By preference each spur should be so arranged relative to the curve of the jaw a, which it intersects, that its longitudinal center will stand approximately at right angles to the cord of an arc of said curve and will be approximately in the center of said cord.

When the spurs q are in position as hereinbefore described, the tool may be used as a wire-stretcher by first engaging the wire between the jaws (t and c at either end or by inserting one end of the jaw a in a loop in the Wire and sticking the spur nearest the wire into something, preferably of wood-as a Wooden fence-post, for example-then while gripping the handle rock the implement until the next spur pierces the wood and still again, if necessary, until the third spur likewise enters the Wood. After the wire is sufficiently stretched and while being held tight by the implement it is fastened. This construction provides for a very powerful and positive wire-stretcher having sufiieient range of action for most practical purposes. As before intimated, it does not matter how the wire is attached to the jaw or jaws so long as the fastening is made secure.

What I claim as my invention, and desire to secure by Letters Patent, is

l. The combination, in a tool of the class designated, of an immovable shank havinga wirereceivingopeningtherein,aninternally-screw threaded sleeve held in said shank against longitudinal movement, a movable shank provided with a screw-threaded part in engagement with said sleeve, a wire-cutting plate or blade connected with said movable shank adjacent the wire-receiving opening in the immovable shank, and means to facilitate the rotation of the sleeve.

2. The combination, in a tool of the class designated, of an immovable shank havinga wirereceiving opening therein,an internally-screwth readed sleeve held in said shank against longitudinal movement, a movable shank provided with a screw-threaded part in engagement with said sleeve, a removable wire-cutting plate or blade connected with both sides of said movable shank adjacent the wire-receiving opening in the immovable shank and overlapping the latter, and means to facilitate the rotation of the sleeve.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

THOMAS D. MILLEA.
