ROBERT W. HALLIDAY, OF CLEVELAND, OHIO.

FENCE-MAKING MACHINE.

Application led June 24, 1907, Serial No. 380,381.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, ROBERT WV. HALLI- DAY, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Fence-l\/[aking Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to an apparatus for making wire fencing and particularly fencing consisting of a number of longitudinal cables formed by twisting together two or more wires, with vertical pickets or cross wires inserted at delinite intervals of the length of said cables and retained by twisting the strands or wires of the cables into gripping engagement with said pickets.

The objects of my invention are to provide an apparatus of this character that may be operated continuously without the necessity for working upon a table or delaying the progress of the work when once begun, and one which, while automatic in its operation as to certain features of construction, will be completely under the control of the operator at all times.

Generally speaking, the invention may be defined as consistingvof the combinations of elements embodied in the claims hereto annexed and illustrated in the drawings, wherein- Figure 1 represents a plan view of a machine constructed in accordance with my invention, Fig. 2 represents a side elevation of said machine, Fig. 3 represents an enlarged sectional view taken on the line 33 of Fig. 1. Fig. 4 represents a sectional view on the line 4 1 of Fig. 3, Fig. 5 represents an enlarged sectional detail on the line 5-5 of Fig. 4L, illustrating the manner in which the strands of wire are twisted to form a cable and the manner in which the pickets are inserted in place. Fig. 6 represents an enlarged sectional detail on the line 6 6 of Fig. +L, and Fig. 7 shows a portion of a fence as woven by my machine.

The apparatus comprises generally wire supplying mechanism, wire twisting mechanism, mechanism for feeding the wire through the twisting mechanism, a drum on which the fence is wound, and means for driving the differentmechanisms.

1 denotes the wire supplying mechanism,

2 the wire twisting mechanism, 8 the wire feeding mechanism, and t the drum on t which the completed fence is wound. These mechanisms are driven by means of belts 6 and 7 and suitable pulleys and shaft ing.

Wire supplying mechanism/. The wire supplying mechanism comprises a suitable number of spools supported by a pair of frames S and 9, each frame comprising a pair of longitudinal members 10 connected by cross members 11. Each of the members 10 is provided, substantially throughout its entire longitudinal extent, with rollers 12, washers 13 being provided adjacent to the ends of the longitudinal members and spacers 12a being provided between the rollers. Each roller receives the side flanges of adjacent spools 14 on which the wire is wound, the width of the frames being suicient to enable the spools to project below the cross members and obtain a firm seat on the rollers 12.

15 denotes a. central frame which is provided between the side frames 8 and 9, preferably by upright members 1G extending therefrom and supporting cross bars 17.

1S denotes a longitudinal shaft supported at one side of the top of the frame 15 and carrying bearings 19 for rollers 20.

21 denotes a pair of longitudinal bars or members extending across the top of the vertical frame 15 at the other side thereof. Bars 21 carry a suitable number of tension devices 22. These tension devices comprise each a frame having at the lower end thereof a roller 23 journaled in the frame and a roller 2st journaled in a vertically adjustable journal box, a pad 25 of rubber or similar yielding material being interposed between the top of 24 and the cross bar 26, there being an adjusting screwl 27 extending through said cross bar and bearing against each of the rubber blocks 25 through plate 25, A pair of wires 28 from the oppositely arranged spools extends over one of the rollers 2O and between the adjacent rollers 23 and 24 of the tension device, whence the pair of wires is led to the twisting mechanism.

)i tension-adjusting device or brake is provided to engage the rims of each of the spools 11i, each of said devices consisting of a iat plate 280 having on its under surface a block 281 of a length to rest on top of the said rims at a point between the axes of the spools and the central frame. The outer end of the plate 280 is given a quarter turn and is provided with a weight which is adjustable thereon to vary the tension exerted on the rims of the spools.

ll'v're tiefst/'ng mec/umism/. The wiretwisting mechanism comprises a plurality of individual twisters 29, with a common operating shaft 30 therefor, and means for operating said shaft. The opposite ends of j y belt which is on the driving pulley 37 onto shaft Btl are carried by journal boxes 3l and Pf3 provided respectively at one side of the main frame, and near the opposite side thereof. 'The shaft 30 is a worm shaft and has one end extended beyond journal box 232 and is provided with a gear R3 meshing with a reduction gear 2H ou the shaft the latter shaft being provided with a pair of idle pulleys 36 and an intermediate lixed pulley 3T whereby the shaft 35 is driven by belts 5 and The shaft 35 is mounted in journal boxes 38 carried by the main frame.

Each twisting` device of the twisting mechanism comprises a worm gear 39 (see Fig. 5) which is provided with a hollow shaft et() rotatably mounted within a journal box 4l carried by a cross bar l2. The rear end of the hollow shaft 40 will be flanged outwardly to retain the shaft in place within the journal box. )rt its inner end and preferably corresponding to the body of the worm gear proper, each gear is provided with a pair of apertures et?, extending therethrough.

It will be apparent that, by the rotation of the worin shaft 30, the worm gears 39 will be rotated and each will twist the pair of wires extending therethrough in the manner illustrated in Fig. 5. The apparatus is so constructed that, when the wires are twisted to form a desired length of cable elet, the operation of the twisting mechanism will be automatically stopped to permit the insertion of the picket in place. This suspension of operation is particularly desirablewhere the picket is of twisted wire, as shown at 45 in Fig. T, the operation of inserting the picket requiring some measurable interval of time. l therefore provide mechanism for automatically stopping the operation of the twisting' mechanism when a certain length of cable has been formed by twisting the individual strands thereof together. A convenient distance between' pickets in fences of this kind is about two or three inches. To cause this automatic cessation of the twisting mechanism, I provide the end of the' g nected with the belt shifter 53.

` one or the other of the loose pulleys 3G.

'282 l with a lever 5l, which is pivoted at one end to a bracket 52 and has its other end con- By adjusting the stops 50 a suitable distance apart, when the head et? has been moved a predetermiued distance in either direction by the rotation of shaft 30, the eye-bolt #LS engages an appropriate stop and quickly shifts theI It will be observed that

belts

5 and 6 are so are ranged that whichever one may be thrown upon the fixed pulley 37 will reverse the direction of rotation of shaft with respect to the direction in which it was previously rotated by the other belt. By suitably adjusting the stops 50, the action of the twisting mechanism will be suspended when any predetermined length of cable 4A has been formed. As soon as the twisting operation is stopped, the operator inserts a picket 45 into the V-shaped shed between the strands adjacent to the worm gear 39 (see Fig. 5) and then, by means of the pivoted batten 54, forces the picket into the apex of the V. It will be observed. from Figs. 4t and 5, that this batten is provided with recesses 55 which enable it to straddle the longitudinal wires with the body portion of the batten in engagement with the picket. The operator grasps the handle 56 and by swinging the batten on its pivot, forces the picket in position. For the purpose of forming an ornamental top for the fence, the ends of the pickets are bent in the manner shown in T, preferably on a former which is used by the operator at his side of the machine, and the end 57 of said picket is placed on the apex of the V formed between the strands j ust previously to the insertion of the body of the second succeeding picket into such apex. Then, when the pickets are properly adjusted, the operator, by means of the belt shifter moves the appropriate belt onto the lixed pulley 3T to cause the worm shaft. 30 to be operated in a direction the reverse to that formerly given to said shaft. It will thus be seen that provision is made for automatically stopping the operation of the mechanism to permit the insertion of pickets. and, as the time consumed for such insertion may vary considerably with different pickets, the starting of the mechanism is entirely under the control of the operator.

lVz/e feeding mcdi@msm-This meehanism comprises a drum on which the completed fence received and by the rotation of which tension is exert-ed on the wires to feed the same from the spools let to the twisting mechanism, together with means the fence and thus draw or feed the wires through the twisting mechanism. The shaft 58 is suitablyjournaled in boxes 6l, 62 and 63 carried by the main frame. The portion of the shaft between boxes 62 and 63 is provided with a pair of ratchet wheels 64 slidably keyed thereto. These ratchet wheels are provided each with teeth 65 adapted to be engaged and operated by pawl mechanism, which will now be described. This pawl mechanism comprises a frame 66 keyed to a rock shaft 67 which may be supported in any suitable manner in the frame.

68 denotes an arm, the lower end of which is rigidly connected to rock shaft 67 and the upper portion of which is provided with a slot 69 which is connected to the head 47 by means of a bolt 70, whereby the movement of the head in traversing the threaded portion 46 of the shaft which operates the twisting mechanism will rock the shaft 67 and the frame 66 thereon.

The frame 66 has toward each end thereof a pair of rounded seats 7l for the reception of the correspondingly rounded lower end of a link 72, the upper end of which engages a corresponding recess 73 in the bottom of a pawl 74. (See Figs. 4 and 6.) pawl is provided at each opposite edge thereof with a metallic plate 75. The frame 66 is provided with a plate 76 projecting rearwardly from the bottom thereof through which plate extends a bolt 77, the upper end of which is connected to a bail 78, the opposite branches of which are in turn pivotally connected to the plates 75. A spring 79 interposed between the plate 76 and a washer 80 on the bolt serves to retain the pawl 74 in engagement with the link 72. The plates are so spaced as to bear against opposite sides of a wheel 64, and by means of the flexible connection between the same and the frame 66 and a retaining plate 81 at the front thereof, each of said pawls is retained in proper operative relation to its ratchet wheel and at the same time there is secured for the pawls such flexibility or adaptability of operation as to enable them to engage the ratchet wheels, notwithstanding the oscillation of frame 66 by the shaft 67. By means of the two sets of recesses 7l and 7 8 and the elongated slot 69, the pawls may be so adjusted as to vary the throw thereof and the amount of rotation of the shaft 58, the ratchet wheels 64 being longitudinally adjustable on the shaft to permit their engagement by the pawls when so shifted. By suitably adjusting the stops 50, the length of the cable twisted before throwing the twisting mechanism out of operation can be adjusted in accordance with the throw of the pawls 74. Shaft 58 is extended beyond the side of the frame and is there providedl 7 with a pulley 82, by means of which the This drum for reeling up the completed fence is operated.

lfvz'ndz'ag drum-The winding drum 83 is carried by a shaft 84 which extends through journals carried by brackets 85. Three such brackets are shown, the drum proper extending between two of the brackets, and the third bracket forming a support for the end of the shaft, which carries a pulley 86 by means of which the shaft is rotated from shaft 58. The drum is preferably a split drum, the ends of the sections being secured together by means of U-shaped shells 87 each having a wedge pin 88 driven through the ends thereof. The end of the fence is inserted between the halves of the drum sections and the fence is wound upon the drum. As will appear from Figs. l and 2, pulley 82 is sufficiently larger than pulley 86 to enable the drum 83 when first started to wind up the fence as fast as it is fed by means of the shaft 58. As the diameter of the drum with the fence thereon increases, the belt 7, being a slack belt provided with a tightener 89, may slip on pulley 86, until such time as the decreased resistance of drum 83 permits the said pulley to be rotated.

From the above description, the operation will be readily understood. The wheels 59, through their engagement with the completed fence, feed the wires from the spools through the twisting mechanism. As soon as the twisting mechanism has formed the wires into cables of the desired length, the head 47, through the rod 49 and lever 5l, shifts one of the driving

belts

5 or 6 onto a loose pulley and the operation of the apparatus is suspended to permit the operator to insert a picket in place. The operator then moves the belt shifter 53 in a proper direction to throw onto the fixed pulley the belt which at the previous operation was running idly. This reverses the direction of movement of the twisting mechanism. After the twisting mechanism has operated a sufficient distance in its new direction, the operation is again automatically stopped by the action of the head 47, the operator inserts the next picket and starts the twisting mechanism in a. direction the reverse of the previous direction by means of the shifter 53. Meanwhile, through the connection of the head 47 with the rock shaft 67, the pawls 7 5 are operated to rotate the feeding drum a distance corresponding to the length of the cables which have been twisted. The rotation of the shaft 58 operates t-he drum 88 in the manner hereinbefore described to reel up the finished fence.
