. Be. it known .that I,- .DAVID C. HEDLUND,

a1 citizen. of t the. United Estates, residing at l in i. the county, of Spokane, State v of -Washington, haveinvented new and useful Improvements in Combination-Tools, of which the following;'is,a specification:

' This invention-relates, to improvements in. combination tools and has to do morei particularly with. thatlvclass of; tool which is employedl'iniie tening a.Wrapping Wire about aIbu'ndle ;of"Wood,1 suchas' a bundle of box or bottoms, and then ..cutting the .wire;

The invention has to do moreparticularly with What is commonly, known as a hand tool,nin contra-distinction toHtha-tclass of tools which are mounted upona fixed sup.-

7 port.-

In the most improved embodimentfof my invention, the same involves .pivotally united levers having handle .ends; on one side of their pivot-a1.juneture, there being a Wiregripping qdevice and a, Wire severing device on the opposite side of "the pivotal uncture. One of the [special novelties consists mounting one element of the Wire gripping deviceupon one leven the other element of the gripping. device being. operatively con-. nected Withmhe remaining lever,,on that side of. the piyotal juncture, opposite, the side on which the severingdeyiceis mounted, or-in other Words, .on that side :of the pivotal,

juncture, Whichl will term the handlelend side. With thisconstr'uction,the coacting members or elementsof the wire gripping. device-are both. actuated, simultaneously, to.- Ward a grippingiposition,"When the handle. ends of the levers are actuated or. contractedfi I By means of thisv construction, gripping device-can be closed from a'Wide openmposi-t tion Witha very slight=movement or slight.

On the opposite side of the pivot 1, fromthe handle end side, is a supporting extension 12 on which is mounted the companion cutting edge member 13, of the severing device. Said member 13 is provided with a cutting edge 14, coacting with the cutting edge 10, said cutting member '13 being secured to the supporting extension 12 by means such as rivets or bolts 15. Thus it will be seen that one member of the cutting device is mounted upon one operative extension of one lever, while the other member is mounted on an operative extension of the other lever. hen the handle ends 2 and 3 are contracted, from the position shown in Fig. 1 to the position shown in Fig. 2, the cutting or severing members will be correspondingly moved to sever the wire.

'I will next describe my novel gripping device and the manner in which the same operates.

The operative end or extension 12 is provided with a bearing 16 which is shown to be of cylindrical form and which is also illustrated as having a cylindrical bore 17. It will be noted that the bearing 16 ,is in very close juxtaposition to the severing device, a point of advantage which will be presently developed in the following description. The end 18 of the bearing member 16, forms an operative part of the gripping device, the end 18 coacting with a companion gripping member which I will now describe in detail. The companion gripping member comprises a shank 19 which is of cylindrical cross-section so as to accurately fit and reciprocate in the bearing 16. On the operative end of the shank 19 is formed a hook 20 which is proportioned so as to contract into and within the bearing 16, as illustrated in Fig; 2. g

I will next describe an important feature of the invention which consists in the operative connection of the shank 19 with the end lever 2 at a point onthe opposite side of the pivotal juncture 1 with respect to that side upon which the severing and gripping de vices are located and operated. In the particular form shown, the leverage extension 4 is bifurcated to form pivotjaws 21. A pivot 22 is suitablyfixed insaid jaws. The shank 19is reduced, as indicated at 23, to fit between said jaws, and the reduced portion 23 is slottedat 24, On the pivot 22 is mounted an anti friction roller 25 which closely fits the slot 24. Theslot 2 1 is of sutficient length to permit of relative move ment of the roller 25 and the pivot 22 in the slot 241 whichis' made necessary by reason of the fact that the shank 19 moves lin early in the bearing 16 whereas the pivot 22 moves about the pivotal juncture 1, as a cen ter. By connecting, operatively, the shank 19 with the lever 2, on the lever end side of the pivot 1, I am able to close the gripping device against the wire and also close the nippers, by one contractive movement of the lever ends 2 and 3.

In operation, it is possible, after wrapping the wire around the bundle to dispose the excess lengths in the gripping device, in the manner as shown in Fig. 1. That length of the wire extending from the gripping device, may be disposed between the severing members 9 and 13, as shown in Fig. 1. Thus in one operation of the lever ends 2 and 3, contracting the same from the position shown in Fig. 1 to the position shown in Fig. 2, it is not only possible to sever the excess wire but also grip the same so that the operator, after completing this operation, will be free to bodily rotate the tool about its longitudinal axis in order to twist the gripped ends of the wire in such a manner-as to tighten and secure the wire about the bundle in firm manner. Wire of sufficient strength is used so that it is not necessary to actually knot the wire in order to securely tiethe bundle. If it is not desired to simultaneously grip and sever the wire, the wire may be gripped and twisted in order to'tie the bundle and then after the bundle is tied, the remainingor excess length of the wire may be severed. However, saving of time is an important factor and where it is possible to save one complete operation, it is desirable so to do, providing that the waste of wire is not too great. 7

Now it is an important feature of this invention to dispose the severing device in such close relation tothe gripping device that the wire may be gripped and severed in one contracting operation of the handle ends without a too great waste of wire. It will be understood that in twisting the ends of a tyingwire it is necessary to have some little excess length in order to form the twist. Now therefore I place the severingdevice sufficiently close to the gripping device to provide fOr this excess length and practically no more. p a I V It will be seen that the extension 12, not only. supports the severing member 13, but the bearing 16, which is one member of the gripping device. Nowthe interdependence between the severing device and the grip; ping device, patentably speaking, resides in such a disposition of these two devices with their, separate pairsof coacting members disposed in such a manner that both of these devices will be moved intoan operativeposition by contractionv of the, handle lever ends 2 and 3. r This is'efi'ected byhaving the severingdevices mounted upon thejle: vers, On oneside of thevpivotal juncture, and connecting the remaining member of the gripping device, operatively with one of said levers on the opposite side of the pivotal juncture of the latter.

It is believed that the novelty and utility of my invention will be clearly understood from the foregoing description and while I have herein shown and described one specific form of my invention, I do not Wish to be limited thereto except for such limitations as the claim may import.

I claim A wire twisting and cutting hand tool comprising in combination, pivotally united crossed nipper and bearing levers having handle ends on one side of their pivotal juncture and the nipper lever and bearing lever each having cutting edges on the re- Copies of this patent may be obtained for five cents each, by addressing the side of their pivotal juncture coactmainin Form mppers, said bearing lever having to ing a twister bearing on the nipper side of the pivotal juncture, a wire hook reciprocable in said bearing and co -acting with said bearing to form a wire gripper, and means connecting said hook and said nipper lever on the handle side of said pivotal juncture whereby movement of the handle ends to- Ward each other will simultaneously move both the bearing and hook into a gripping position and close said cutting or nipper edges, substantially as described.

In testimony that I claim the foregoing as my own, I hereby aflix my signature.
