11 Claims.

.. This invention relates to tools for twisting staplesand clamping the same about intersecting fence wires tobind such wires together, and

particularly represents improvements over the tool and apparatus used in connection therewith shownin. my Patent No. 1,903,830, dated April 18, 1933. v The principal objects of the present invention are to provide a tool whose construction and. operation is simplified over the previous structure; and to provide a unit for supporting and locating the tool and fencewires in cooperative relation with each other and'with the staple to be tied, which is simpler, lighter and easier to manipulate than the unit previously used for this purpose.

.These'objects I accomplish by means of such structure and relative arrangement of parts as will. fully appear by a perusalof the following specification and claims.

In the drawings similar characters of reference indicate corresponding partsin the several views:

. Figure 1 is a side view of the tool and supporting unit as in operation.

Figure 2 is a view partly in section of the jaw unit of the tool detached.

' .Figure 3 is a fragmentary transverse section of the tool on; the line 33 of Figure 1..

Figure/l is an end view of the jaws.

Figure is a fragmentary side View of the tool as initially engaged with the supporting unit and staple, the unit being shown in section. Figure 6' is a plan view of the supporting unit arid tool as on the line 6 6 of Figure 5 showing the fence wires and the staple engaged therewith in position to be twisted or tied.

Figure '7 isa view similar to Figure 5 showing the tool arms as swung down to bend the staple legs to position and with the staple as initially engaged with the jaws. J

Referring now more particularly to the characters of reference on the drawings, the tool comprises a pair of spaced bars I which at and for a certain distance from the. rear end are countersunk in and rigidly secured in a block 2 extending lengthwise of and depending from said .bars. At their forward end the bars are bent down somewhat sharply as shown at 3, the bottom of the bends beingformed as hooks 4 facing upwardly. and rearwardly at an angle to the straight portion of the bars; the tips of the hook portions being rounded. The rear or under faces of the bends 3 above the hook portion are formed with concave saddles 5 for locating engagement with the horizontal fence wire6 when the tool is inbperation, and which wire is then directly above the tip of the hooksd. Said faces. of the -bends"on their adjacent sides or edges are also formed with-recesses orgrooves l which are concavely curved with the saddle 5 to engage the bent rearwardly of the crank handle I I.

end or hook portion 8 of a staple, and extending rearwardly therefrom to also engage the adjacent straight portions of the legs 9 .of the staple, as clearly shown in Figure 7.

Turnably and slidably mounted in the block 2 parallel andcentrally between the bars I is a barrel I0 whose rear end is provided with a crank handle by means of which it may be manipulated. Slidably fitted in the barrel is a split spring shank l2 held against rotation by a cross pin l3 mountedin the barrel and projecting between the split sections of the shank. Opposed jaws M are formed at the forward end of the shank and project outwardly from the adjacent end of the barrel. The outer faces of the jaws at the back are tapered as at 15 to engage the correspondingly tapered jaws of the forward relation partway across the jaw gap or slot, the spacing between the lugs lengthwise of the jaw face being approximately equal to the outside dimensions between the legs of a staple. The purpose of this will be seen later.

The rear end of the shank is formed as a reduced threaded stem ll, engaged by the tapped hub I8 ofa hand wheel l9 disposed adjacent but The exterior of the hub is also threaded as at 20 and engages the adjacent tapped portion of the barrel Ill. The sets of threads are cut in the same direction (right hand) but the pitch of the threads of the stem 11 is greater than that of the threads 20. Bythis arrangement, when the hand wheel is turned to the right it will advance into the barrel but at the same time the stem I! will be drawn outwardly through the hub a greater distance due to the increase in pitch of the threads of the member I! relative to the threads 28.. This will cause the jaws to be retracted into the barrel and drawn together to firmly grip the legs of a staple therebetween.

. By making the difiference in pitch of the two threadsrelatively small a very great leverage or clamping pressure may be had without using a large hand wheel, and a very firm grip on the tapped bore of the hub l8. a Y

From one end only of the grip- The unit associated with a fence to support the 3. A gripping tool comprising a barrel, a split spring shank slidable in the barrel, jaws on the split end of the shank projecting from one end of the barrel, means between the shank and barrel whereby the jaws will be contracted with the longitudinal movement of the shank toward the opposite end of the barrel, a rotary hand member mounted axially of and on said opposite end of the barrel for movement lengthwise thereof, and means between said member and the adjacent end of the shank for moving the latter lengthwise of the barrel with the rotation and longitudinal movement of the member but a lesser distance than that of said member.

4. A gripping tool comprising a barrel, a split spring shank slidable in the barrel, jaws on the split end of the shank projecting from one end of the barrel, means between the shank and barrel whereby the jaws will be contracted with the longitudinal movement of the shank toward the opposite end of the barrel, a rotary hand member mounted axially of and on said opposite end of the barrel for movement lengthwise thereof, and means between said member and the adjacent end of the shank for moving the latter lengthwise of the barrel a certain distance in one direction with the rotation and longitudinal movement of the member a greater distance in the opposite direction.

5. In an apparatus for tying fence wires together by means of staples at the points of intersection of the horizontal and vertical wires of the fence, said apparatus including a tool to twist a staple engaged with the crossed wires; an upright adapted to be disposed behind the fence, a single block slidably mounted on and projecting forwardly from the upright, separate cradles on the block to locate a horizontal wire and the adjacent portion of a vertical wire, means on the block to support and locate a staple in predetermined relation to the located wires, and means on the block to removably locate the tool in position to engage and twist a supported staple.

6. In an apparatus for tying fence wires together by means of staples at the points of intersection of the horizontal and vertical wires of the fence, said apparatus including a tool to twist a staple engaged with the crossed wires; an upright adapted to be disposed behind the fence, a slide block adjustably mounted on and projecting forwardly from the upright, horizontally spaced cradles on the block to support a horizontal wire, a vertical cradle on the block in front .of and below said first cradles and centrally therebetween to locate the adjacent portion of a vertical wire, a horizontal web on the block between and below the horizontal cradles and back of the vertical cradle to support a staple in straddling relation to the located wires, and means on said block to engage and locate the tool in operating position relative to the crossed wires and staple.

'7. In an apparatus for tying fence wires together by means of staples at the points of intersection of the horizontal and vertical wires of the fence, said apparatus including a tool to twist a staple engaged with the crossed wires; an upright adapted to be disposed behind the fence, a slide block adjustably mounted on and projecting forwardly from the upright, horizontally spaced cradles on the block to support a horizontal wire, a vertical cradle on the block in front of and below said first cradles and centrally therebetween to locate the adjacent portion of a vertical wire, a horizontal web on the block between and below the horizontal cradles and back of the vertical cradle to support a staple in straddling relation to the located wires, the tool including horizontally spaced bars to straddle the vertical wire and formed with hook portions at their outer ends, and means on the block to releasably engage said elements and locate the tool in an operative position relative to the crossed wires and staple.
