Be it known that I, JONATHAN HARRIS, a

citizen of the United States, and a resident of Cleveland, county of Ouyahoga, State of Ohio,.have invented certain new and useful Improvements in Automatic Fence-Making Machinery, of which I hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same. p

e The objects of the invention are to provide automatic mechanism for attaching wire 'staples'of the form described to the crossingpoints of the running and stay wires of a wire fence; and the invention consists in the mechanism for feeding the running-wiresspaced, to the desired height of the fence and feeding the stay-wires at regular intervals trans- 'versely across the running-wires 1n the-van ous guides for the running and stay wires, in

the forming-dies in which the clamps are tightly secured to the wire crossings, means for winding the extremities of the stay-wires about the outer 'running-wires, mechanism tions of the dies, means for crimping the run- Ding-wires as soon as the fence has been com pleted, and in the combinationand arran ement of the parts to operate automatica ly in unison with predetermined regular sequence and in the construction of various details, as hereinafter described, shown in the accompanying drawings, and specifically pointed out in the claims.

- Inthe accompanying drawings, Figurel is an elevation of the complete machine from the end into which the running-wires are fed,

is wound, and 11 the belt connectin them.

12 is abar upon which the lower ie-blocks 9o 13 are moun'ted. This barreciprocates ver; tically between'fthe frames 1 in guides G therein and is moved by means of thecam's 14 upon the main shaft,"which engage rollers 15 upon the bar. Upon this bar are mounted also the winders 16, which wrap the ends of the stay-wires upon the outer runningwires. Gears 17 upon these winders engage racks 18, which are elevated by the cams 19 on the main shaft by means of the,interven-' ing levers 20, pivoted at 21 on the bar 22,- connecting the side frames 1. provided with a stem, which is jointed at 23 to permit free movement.

The running-wires R are fedover pulleys 2.4 on a shaft at the base of the machine 1O isthe reel upon whichthe finished fence v I Each rack is tension to keep the Wires taut, and the crimping and feeding rollers are constructedas follows:

Each roll is provided with two heads 30, connecting which at regular intervals are placed the cylinders 31, which may be made of gas-pipe or steel tubing. The cylinders in one roll intermesh with the cylinders in the other roll and as the fence is pressed be tween them crimp the running-wires as well as exert a strong pull upon the fence.

When thecylinders are tubes, they can be secured in any suitable manner to the heads, as by means of the cast annular flanges 32 upon the heads, which are inserted in the tubes. (See Fig. 9.) Each head is provided with the spur-gear 33 upon its edge, which gears engage so that the rolls shall move in unison.

The rolls are rotated by means of the segment 34, mounted freely upon the shaft 35 of the lower roll and provided with the spring pressed pin 36, which engages the pin hole 37 when moved in one direction, but is permitted to slide and escape from the'hole when moved in the other direction by means of the incline 38. A pawl 39 and ratchet 40 upon the reel-shaft 41 prevent the fence from pulling back, whatever the tension may be.

The segment 34 is provided with a segmental gear 42 and is oscillated by means of the rack 43, which rests upon a roller 44 to support it in contact with the segment. The rack is pivotally connected at 45'with the rock-arm 46, mounted upon a shaft 47 in the side frames. A cam 48 upon the main shaft moves the rack forward to rotate the rolls, and a spring 49 returns thearm. The arm is slotted at 50 to give adjustment to the throw of the rack, so as to afford change of 'movement to accommodate the spacing of the stay-wires, and a nut 51 upon the pivotpin secures it where required.

The bearing of the lower roll is made adjustable by means of the set-screws 52, so that the bearing can be set up as closely as is necessary.

The stay-wire S is fed into the machine under the running-wires by means of the grooved rollers 53 and 54, having first passed through a set of straighteners 55.

The lower roller is seen in the drawings to be the driving-roller, and the rollers are geared together at 56, so as to move in exact unison. A miter-wheel 57 on the shaft 58 of the lower roll is driven by means of the mitergear 59 on a shaft 60 at right angles to the roller-shaft, and a spur-gear P on this shaft is engaged by the rack 61, which is vertically reciprocated by means of the cam 62 upon the main shaft and the arm 63, pivoted upon the frame. The rack is jointed at 64 to give freedom of movement and moves through a guide 65.

After entering the machine the stay-wire is fed across the dies under the running-wires, through grooves prepared for it in the upper surface of the dies, and through guides which insure its entering the dies correctly and is then cut off by means of the cutters 66 and 67, one upon the upper and one upon the lower die-bar. As soon as the wires are in position, as seen in Fig. 4, the staples are fed to the dies by me ans of grooved conduit-s 68, in which they slide and straddle over the running-wires. A slight rise 69 in the bottom of the conduit stops them until the vibrating fingers 70 engage them and carry them forward until their forward ends pass under the stay-wire, and an upward curve 71 in the lower die in continuation of the groove 72 in the top of the die elevates the free ends of the staple, so that they stand above the running-wire ready to be wrapped thereover. As the lower dies ascend the upper die 73 comes first into contact with loop 74 of the staple and rigidly holds it in )osition. A spring a permits this die to rise arther while still retaining hold upon the staple. At this point it is necessary that the vertically-elevated ends of the staple should be bent inward from either side over the running-wire. Thisoperation is accomplishedv by means of the horizontally-moving dies 75 and 76, which are secured to the bars 78 and 79, which move in grooves in the die-blocks and which pass one another, as seen in Fig. 5, the ends of the staples being bent on different planes, so that they can be bent over the running-wire without interfering. The bars 78 and 79 are reciprocated in opposite directions by means of the cam 80 upon the main shaft, which is wider at 81 than elsewhere, both sides being alike. The levers 82 and 83, pivoted at 84 upon the lower die-bar, engage the sliding bars 78 and 79 and crossing at a common pivotal part engage different sides of the cam 80, so that they move in opposite directions, while a slot 85 in the outer bar permits the pin 86, attached to the lever 83, to enter the inner bar. As soon as the ends of the staples have been bent horizontally over the running-wires it is necessary to further wrap them vertically downward. Hence as the lower dies rise the staple comes into contact with the upper stationary die 87, which completes the operation, and the staple is firmly attached to both wires, forming a oint, as seen in Fig. 13.

The guides G, afiixed to the lower bar, are seen to be provided with longitudinal openings 89, through which the stay-wire is fed, and as soon as the staples are attached to the .wire' crossings the lower die-bar drops, and the upper portions of the guides being hinged I at 90 they lift up and the wires .come out without difiiculty. Springs 91 return them.

The finger 70, which feeds the staples to the dies, is oscillated by'means of the slotted arm 100 upon the common shaft 101and a 1 pin 102 in an arm 103', attached to the upper bar 2.

It will be seen thatwhenthe lowerv bar 12' descends the slotted arm will be drawn upward at its outer end, thus moving the finger 70 forward and carrying the staplewith it,

on said bars between which the running and stay wires are located, dies in saidblocks adapted to compress said staples about the wire crossings, means for operating the lower die-bar and dies, and a feed and crimping device for the running-wires consisting of stay wires cross provided with. a groove havrolls between which the completed fence passes, each roll comprising a head at either end and ,spacedfcylinders, the cylinders of one roll engaging between the cylinders of the other roll, and means for operating the rolls, substantially as described.
