' To (ML whom it may concern/:1

Be it known that I, GEORGE W. SoHocK, a citizen of the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented new and useful Improvements in Wire-Fence Machines, of which the following is a specification.

are in the form of clips which are cut and bent into the required shape reparatory to being placed into a suitable opper, from which they fall by gravity onto a feeding mechanism operated by a swinging delivery device,

. point which grasps the clip and carries'it to the intersection of the Wires of the fence,

where it is operated u on by suitable dies and cle'nched in place, a l as will be more fully described hereinafter, illustrated in the accompanying drawings, and finally pointedout in the appended claims.

In thedrawings, Figure 1 is a view, partly I in side elevation and partly in section, of the feeding means, the deliverydevice, and the die, embodying all the features of my invention and showing in dotted lines two positions of the delivery device with the clip carried thereby. Fig. 2 is a front elevation looking the clips 3.

in the direction of the arrows in Fig. 1 with the delivery device shown in its lowered posi-.

tion. Fig. 3 is a plan view of the ho per and its feeding means with the latter s own in dotted lines in one of its ositions. Fig. 4 is va side elevation of the eliyery device with the clip-applied to the fence-wires. Fig. 5 is a front elevationlooking in the direction of the arrows in Fig. 1 with the delivery device shown in its raised position, and Fig. 6 is a perspective view of the clip.

Making renewed reference to the drawings, wherein like characters of notation indicate corresponding parts appearing in the several illustrations, and references being had thereto, 1 designates a suitable face-board or frame of themachine, and 2 indicates a hopper for This ho .per preferably consists of a casing with a bacl; cured the angular end plate 5, and to the face- -board 4, to which is see,

board 1 and projecting toward the angular plate 5 is another plate 6, all of which form a vertical runway for the clips, the runway be ing slotted longitudinally at the front, so as to permit the end of the clips to project therefrorn,as shown. The clips havlng been previously out are bent into the required sha e. One of the clipsis-shown in Fig. 6 as consisting of a plate 7, which is provided with two longitudinal cuts, forming a tongue 7 upon each side and a central rojection 7 The tongues may be bent bac r upon the plate, as shown, and then the plate is provided with a central longitudinal rentrant portion 7 which is adapted to partially envelop the longitudinal wire of the fence, while the tongues engage the stay-wire, arranged at right angles to the longitudinal wires. When these tongues are bent up and clenched around the stay-wires, as will be described hereinafter, the wires are held against displacement.

The means for operating the die andthe means for operating the delivery device are not shown in the present drawings, and they form no part of the present invention, which consists of that portion of a wire-fence machine which feeds and delivers the tie to the die. 1

The feeding mechanism for the clipsis mounted beneath the hopper and consists of v 1 a longitudinally-movable rod 8, supported in spring 10, mounted thereon and which has I one end bearing against a collar 11. This collar has a tangential arm 12, from which extend clip-supporting {fingers 13, which are spaced apart. a sufiicient distance to permit the projecting end 7 b of the clip to pass therebetween when the fingers are'released from engagement with the plate or side portion of the clip, as shown in dotted lines in Fig. 3.

In order that the clips may have a progressive feed, it is necessary to support a row of clips in the hopper while the bottom one is being fed to the delivery device, and for this purpose the endwise-movable rod 8 is provided with a collar 14, made fast to the rod and having a tangential arm 15, from which extends a supporting-finger 16, that projects through an opening in the back-board 4 of the hopper and into the latter in the path of the clips, so that when the bar 8 is shifted against the tension of the spring 10 the fingers 13 are withdrawn from beneath the bottom clip and the latter is permitted to drop onto the delivery device. At the same time the finger 16 is projected into the hopper between the tongues of the bottom clips and in the path of the plate portion of the clip immediately above, asshown in dotted lines in Figs. 1 and 3, wherefore the entire row of clips is supported during the delivery of the bottom clip. WVhen the shaft 8 is released, the spring 10 will return the shaft to its normal position and project the fingers 18 into the path of the plate of the neXt clip, while the finger 16 will be retracted from the hopper, and the entire row of clips therein will drop upon the fingers 13. This feeding mechanism is operated by a vibrating or swinging delivery device by providing a lug 17 on the collar 11 and disposing it within the path of the free end of the swinging-clip deliverer or carrier. This delivery mechanism consists of a swinging anvil 20, rigidly. mounted upon a rock-shaft 21 and having at its free end a bifurcated jaw or claw 22 for engaging the ex tension 7 of the clip when the latter drops from the hopper. This swinging anvil is provided with a transverse slot 23, in which is pivoted an arm 24, having secured. thereto a flat spring 25,. which envelops the pivoted end of the arm and has its free end in engagement with the end of the slot, so as to normally hold the opposite end of the arm projected forwardly. To the other end of the arm 24 is pivoted a gripping member 26, the lower end of which has a socket member 27, in which is mounted a coil-spring 28, which bears against the face of the anvil, and thus normally holds the free or opposite ends of the gripping member toward the anvil. From this construction it will be seen that the gripping member 26 not only has a swing ing movement on its pivot, but also a movement longitudinally of the anvil, so that its free end may be normally held projected in the path of the clip but it is adapted to be retracted or'slid rearwardly when engaged with the wire of the fence.

When the machine is in operation, the upward movement of the swinging delivery member 20 will imp art an endwise movement to the feeding-bar 8 by striking the lug 17 on the collar 11, and thus permit one of the clips 7 to drop down upon said delivery member. Upon its forward movement the collar 11 is released and the spring 10 forces the bar 8 and supportingfingers l3 forwardly, so as to check the feeding or descent of the clips, while the claws 22 force the clip into engagement with the gripping member 26, and the clip in such position is carried down, as shown by dotted lines in Fig. 1. When the delivery member has reached the limit of its downward movement, the tongues 7 of the clip have straddled the stay-wire of the fence and the gripping member 26 has by contact with the wires been forced rearwardly or upwardly. With the parts in these positions a plunger or die 29 is operated by mechanism (not shown) to clench the tongues 7 of the clip around the stay-wire A of the fence, while the longitudinally-reentrant portion 7 of the clip partially incloses the longitudinal wire B of the fence, the delivery member 20 serving as an anvil and resisting the pressure of the die, all as shown by dotted lines in Fig. 1. Upon the reverse movement of the delivery member the gripping member 26 will by virtue of its loose pivoted connection with the delivery member slide rearwardly and clear the end of the clip, as shown in dotted lines in Fig. 4, and when free of all obstacles this gripping member will be again projected forwardly by the spring 25, so as to bring its free end within the path of a lug 30, depending from the bottom of the hopper, said lug serving to arrest the movement of the gripping member and hold it in released position until the next clip has been fed to the delivery device.
