This invention relatesto the assembling of parts of line fences of that nature which consist of horizontal wires afiixed to fence posts, and vertical wires secured to thehorizontal wires at intervals, and which are apd j H j j I v ded. with a socketed block 4 to form a templied after the horizontal wires have been placed and stretched. V i

In thus securing the wires together, I

make use of wire staples of special form and.

9 so that no twisting of the fence wires themselves is necessary; and the ob ect of thls lll Vention is to provide an apparatus by means of which such staples may be tightly wound and clamped about the wires in such a man- 5 ner that the staples are placed under a considerable tension, and the wires are consequently held together and against slipplng with considerable pressure.

Fig. 8 is a perspective'view of the staple fill-fin its initial form. r d a j Referring now more particularly to the characters of reference on the drawings, the

fence to be assembled includes horizontal wires l and vertical wires 2, the former be- 5. ing secured to'the end fence-posts before the wires 2 aresecured thereto. To initially position the individual wires Qinplace and to also locateand support the tool in its proper position relative to the-several wires Q9 1, I'pi'oyide a frame which consists of a'pair cross section on theli of spaced and connected uprights 3 adapted when infuse tobe placed behind the wires nd to i ns the s me nd t be su ported by the ground. J

Adjacent its lower end the frame is pro porar'ysupport for the lower end of a wire 2mm sf u d pa he. ock t being d e.- posedcentrally between the uprights.

elow the position of the wires 1, blocks 5'are removably mounted in opposed pairs on the forward face ofthe uprights. Said l s h upstanding a es 6 distress d outwardly of the uprights so as to form locating means for the wires 1, as shown n F 1g. 1. Intlns manner. the w res 1 en eas t e pi r sd es of e b ock et e base of the flanges, and are thus definitely positioned relative to the blocks. Formed with th e blocks and projecting part way .acrossthe space between the uprights are lateral extensions formed on their back sides with downwardly facing and oppositely alined saddles 8, which are thus disposed .backlof W es a d 2, he et er. beifi in front of the wires 1. I d v The tool to be usedwith the locating and pport n -sw m ca puses pac d bars 9 having a depending bend 10 at their for-; ward ends which are provided adjacent the 0 bottom with outward projecting lugs 11 adapted to seat in the saddles 8. "The'spacing of the bars is such as to enable them to readily project between the block extensions 7 and the saddles 8 from in front of the same. The front faces of the bends l0 at theiradjacent sides or edges are provided with-recesses'or grooves 12 whichare shaped and curved to conform to the bent end portion;-1 3 of the securing staple whose legs 9 l thenproject forwardly in substantially parallel relation to the bars. The spacing of the legs and the bend is such that the staple may be easily engaged with and straddle one of the wires 1 and 2 in the manner spring shank 17 on the forward split end of which are jaws 18, while its rear solid end is threaded for a certain length as at 19. The outer faces of the jaws are tapered at the back and engage the similarly tapered bore of the cylinder, so that upon pulling back on the shank, the jaws will be contracted. The cylinder is disposed so that the space between the jaws when horizontally disposed, is substantially in line with the legs of a staple supported in the bar recesses in the manner previously described, 7

Turnably mounted on the outer end of the cylinder is a hub 20 having a crank handle arm 21 projecting radially therefrom. The cylinder is provided with ratchet teeth 22 thereabout which are engaged by the dog 23 in the hub, the arrangement being such that the cylinder will rotate with the handle only when the latter is rotated in a clockwise direction. Screwed on to the part 19 back of the hub is a hand nut 24 provided with a radial bar 25 to facilitate its turning. This nut always abuts against the rear end of the cylinder and is partially overlapped and engaged by the hub in a manner to prevent outward movement of the nut relative to the cylinder without interfering with its rotation. The porion of the nut overlapped by the hub is provided with ratchet teeth 26 thereabout, which are cut in the direction opposite to those on the hub. These teeth are engaged by a dog 27 mounted in the hub and arranged to be raised when necessary by a finger pad 28 connected thereto and extending to the exterior of the hub, preferably adjacent the handle arm.

In operation the locating frame is first disposed relative to the fence as shown and described, the wire 2 to be connected is placed in position, and the staple is then engaged with the wires. The tool is then mounted in connection with the frame and so that the bars 9 straddle the wire 2 by engaging the lugs 11 by a downward movement from above the staple with a co-operating pair of saddles. The bars 9 are disposed in front of the portions 10 and above the lugs 11. The tool is then swung down somewhat so that the staple is properly located in the groove 12. With this movement of the tool, a leverage action is imparted to the staple legs, causing the bent end of the staple to snugly engage the wires 1 and 2. lVith the jaws open and horizontally disposed, the cylinder is advanced so that the staple legs project between the jaws a considerable distance. The jaws are then clamped against the legs by holding the cylinder stationary, releasing the dog 27 from the nut 24, and turning the latter in a clockwise direction to pull the jaw shank in a jaw closing direction. hen the jaws are thus tightly engaged with the staple, the cylinder is turned by means of the handle and the staple legs become consequently twisted about each other until they have assumed the position shown in Fig. 3, at which time they are tightly engaged with both wires 1 and 2, and the jaws abut against shoulders 5 formed at the forward end of the grooves. During this operation the flanges 6 prevent the wire 1 from'being bent or deflected outwardly by the pulling action of the tool, since the only portion of this wire which is free to thus bendis the very short stretch between the adjacent flanges.

It will be noted that the jaws 18, at the back of their gripping faces, which are relatively shallow, are relieved or cut back as at A so that an opening of considerable size is formed from side to side of the jaws. This feature has been found to be very essential to the proper handlin of the staples. The presence of the opening eliminates all chance of the staple legs being gripped at their outer ends, and insures such grip as being had relatively close to the bend of the legs, where a grip is most efficient in the twisting of the staple.

The opening also leaves the ends or points of the staple free to roll or move about as the staple is being twisted, which eliminates all chance of the staple pulling from the jaws with the twisting operation.

The legs of the staple, being of spring steel, then snap off at the jaws, and the cylinder can be retracted. The opening of the jaws, to en age another staple, is done by turning back on the handle arm 21. With this movement the cylinder remains stationary because the dog 23 is then merely backed around the ratchets 22. The dog 27 however being oppositely disposed, is taking hold of the ratchets 26 and will impart a retractive movement to the nut 24. The tool is then removed from the saddles and applied in connection with another wire 1 and saddle unit to again tie the next staple in place. When the wire 2 has been secured at all intersecting points, the frame structure is removed from its position and shifted to where another wire 2 is to be placed. This is easily done by lifting up on the wires 1 sufiiciently to clear the flanges 6. The frame structure may then of course be moved along the fence for similar placement wherever desired.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to do not form a departure from the spirit of the invention, as defined by the appended claims.
