CORNELIUS K. OHAPIN, OF LANSING, MICHIGAN.

WIRE-FENCE MACHINE Specification of Letters Patent.

Patented May 26, 1908.

Application filed March 21, 1907. Serial No. 363,602.

To all whom it may concern:

Be it known that I, CORNELIUS K. CHAPIN, a citizen of the United States, residing at Lansing, in the county of Ingham and State of Michigan, have invented a new and useful Wire-Fence Machine, of which the following is a specification.

This invention relates to machines employed in the manufacture of wire fences.

The machine forming the subject of the present invention is designed to manufacture fences of that type in which the longitudinal strands or warps are each formed of a pair of wires, and the transverse or picket members are arranged at regular intervals, and are confined in place by the twisting of the wires between them, each pair of wires being twisted continuously in one direction until the insertion of a picket, and then twisted continuously in the opposite direction until the insertion of another icket, after which the twist is made in the irst direction.

One of the principal objects of the invention is to rovide a machine in which the twist may e made tighter at points immediately adjacent the opposite sides of the picket members, in order to firmly lock the pickets in'place, while the intermediate portion of the cables may be twisted more loosely, if necessary.

A further object of the invention is to pro vide amachine of the most simple construction by which the twisting operations may be carried on with uniformity, and stopped in such manner as to form sheds for the introduction of the pickets at regular intervals.

A still further object of the invention is to provide a fence machine having a variable take up for-the finished fabric, the take up being arranged to operate at different speeds during the twisting operation.

A still further object of the invention is to provide a take up or feed that is started into operation after the beginning of the twisting operation, and ceases to operate before the completion of each twisting operation.

With these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of con struction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form,

proportions, size and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings :Figure 1 is a side elevation of a wire fence machine constructed in accordance with the invention. Fig. 2 is a plan view of the same. Fig. 3 is a transverse sectional view of a portion of the machine on the line 3-3 of Fig. 2, showing the arrangement of the twisters and the beating up fingers.

Fig. 16 is a similar view of one of the disks or plates at the end of the winding roller. Figs. 17 and 18 illustrate a modified construction of the feeding mechanism. Fig. 19 is a detail view on an enlarged scale of a portion of the fence.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawin s.

Ihe working parts of the machine are supported on a suitable framework 10, having bearings for the sup ort of a main shaft 11,

the shaft 12 of the feed or take up, and the shaft 13 of the drum or roller on which the finished fabric is wound.

At one end of the machine is arranged a transversely disposed bar 15 having a vertical web 16, and a horizontal web 17 the vertical web being provided with openings 18 that are disposed in alinement with, and are arranged for the passage of twister heads 19, the number of twister heads employed being dependent on the character of the fence manufactured, nine of such twister heads being shown in the present instance. Each twister head is in the form of a disk 20 having a pair of diametrically opposed openings 21 for the passage of the longitudinal wires :0, of which each cable is formed. The disk is carried by a reduced neck 22 which projects from the forward end of a short shaft 24 mounted in a bearing in a standard 25,- the base of which is bolted to the web 17. Two of these shafts 24 are provided with small pinions 26, the teeth of which intermesh with the teeth of a gear wheel 27 that is mounted on a counter-shaft 28 supported in suitable bearings 29, and the shaft of these twisters receive motion in the same direction at the same speed.

The shafts of the-second, third, fourth, fifth, siXth, and seventh, twisters are provided with sprocket wheels 30 which are connected by a link belt 31, said belt being held in engagement with the sprocket wheels of idler rolls 32 that are journaled on studbolts 33 carried by the vertical web 16 at points between the several twister heads. The shafts of the seventh, eighth, andininth, twister headsare provided with gears 34 that intermesh in a continuous train, these twisters being arranged so closely together that better results are obtained from direct gear transmission, than by the employment of the sprocket wheels and belt.

All of the sprocket wheels, gear wheels, and the shafts which carry them are providedrwith passages 35 for the wires on, the wires being supplied from suitable reels, not shown.

Projecting from the forward face of the" vertical web 16 is a series of projections 36 arranged in the same horizontal plane, and spaced apart at the twister heads, these projections forming a practically continuous support on which the picket is placed, and on which it rests before the beating up operation.

At a point below, and in advance of the bar 15, is arranged a transversely disposed shaft 37, supported in hangers 38, and carrying at intervals anumber of beating up fingers 39, there being preferably a pair of fingers for each of the cables or longitudinal strands of the fence, and one finger of each pair being disposed on each side of the cable. At one side of the machine is a lever 40 that is secured to the shaft 37, and is arranged within convenient reach of the operator, and by moving the lever toward the right of Fig. 1, may force the picket from the supporting lugs 36 into the apex of the shed and hold the same tightly in place until the twisting operation behind the newly introduced picket has commenced, after which the fingers may be allowed to return to normal position in readiness to act upon a second picket.

On the shaft 11, previously referred to, is mounted a pair of

loose pulleys

43 and 44,

that are driven, respectively, by

belts

45 and 46, the belt 45 turning the pulley 43 in one direction, while the belt 46 turns the pulley 44 in the opposite direction. Keyed to the shaft is a pair of

clutches

47 and 48, said clutches being united by a centrally disposed sleeve 50 having an annular groove for the reception of the lower end of an operating lever 51 that is fulcrumed on a pin 52, and is provided with an operating handle 53 by which the pair of clutches may be moved in either direction, movement in one direction locking the pulley 43 to the shaft, and movement in the opposite direction releasing the pulley 43 and locking the pulley 44 to said shaft, so that the shaft may be rotated alternately in opposite directions.

The shaft 11 carries a pinion 55 that is in constant mesh with the gear 27, and in operation will rotate the latter first in one direction, and then in the opposite direction, so that all of the twisters will receive a corresponding movement, it being designed to twist the wires alternately in opposite directions between successive pickets. The gear 27 receives one complete rotation at each operation, and the movement is timed and governed by a disk 56 that is secured to the shaft 28, and is provided with a peripheral notch 57 that is arranged to receive a stop lug 58 carried by a slidable bar 59. The bar is mounted near one end in a guide 60 carried by the frame, and at its opposite end is pivotally connected to the operating lever 51. The bar is further guided by a hanger 62, and between the hanger and guide 60 the shaft is surrounded by two helical compression springs 63 and 64 that are se arated from each other by a collar 65 rigid fy secured to the shaft. When at rest, the s rings tend to maintain the bar 59 in a centra position with the lug 58 in the notch 57, and thus stop rotative movement of the disk 56, and the twister heads, and at the same time move the operating lever 51. to a vertical position where both 0 utches are inoperative, and the

pulleys

43 and 44 may be rotated idly. In the operation of this portion of the mechanism, the operator grasps the handle 53 and moves the latter to the right, pulling the rod 59 against the stress of the spring 64, and moving the lug 58 from the notch 57. At the same time the clutch 47 is moved into engagement with the clutch face 43, and the latter is locked to the shaft 11, whereupon movement is transferred to the shaft, and from thence through gear 55 to the gear 27 and all of the twister heads. The disk 56 rotates, and as soon as its movement commences, the operator will release the handle 53, and spring 64 will thereupon press the side of the lug 58 against the vertical side of the disk 56, and the partswill continue in this relation until. disk 56 has made one complete revolution, this revolution being su'l'li cient to revolve all of the twister heads and twist the cables between two pickets. When the notch 57 of the disk comes opposite the lug 58, the latter is forced into the'notch by spring 64, and the further movement of the disk is prevented. At the same time the clutch lever moves to the central position, and the pulley 43 is released, and allowed to rotate idly. A fresh picket is then placed in position on the projections 36, and the operating lever 40 is moved to engage the fingers 59 with said picket, the latter being forced in the apex of the shed. The operator then pulls the handle 53 of the shaft and moves the lug 58 out of the notch against the stress of the spring 63. This movement forces the clutch 48 into engagement with the clutch face of the pulley 44, and the shaft 11 is again rotated, but this time in the opposite direction, and movement is transferred, as before, to the twister heads, save that they turn in the opposite direction. As soon as the movement starts, the notch 57 passes beyond the lug 58, and the operator then releases the handle 53. As the disk 56 completes its rotation, the notch 57 again moves opposite the lug 58, and the latter is forced into the notch by the spring 63, thus again stopping the rotative movement, and again forcing the clutch operating lever to the vertical or central position, so that clutch 48 is moved from engagement with. the pulley 44, and the latter rotates idly.

The shaft 12, previously referred to, carries a take up or feed drum which may be formed of any material. stance awooden drum is employed, and in the face of the drum are secured the base plates 71 of feeding fingers 72. These feeding fingers are arranged in pairs, the space between each pair being designed to receive one of the longitudinal cables of the fence, and there are as many pairs of fingers as there are cables in the fence. The drum is shown as provided with four sets of fingers arranged at ninety degrees apart, each set extending completely across the drum in a direction para lel with the axis thereof. Secured to the end of the drum is a disk 74, carrying a series of lugs 75, there being four of such lugs in the present instance, and said lugs being spaced at ninety-degrees from each other. Through these lugs the feed or take up drum is intermittently rotated.

One end of the shaft 12 finds a bearing in a hollow shaft 76, that is in the form of a hub extending inward from the rear face of a bevel gear 77, and this hollow shaft or hub is mounted in a suitable bearing 78 carried by In the present ina bracket 79 that forms a part of, or is carried by the main frame.

To the side frame is bolted a bracket 80 having a bearing for one end of the main shaft 11, and being further provided with a bearing for the end of a shaft 81, the opposite end of which is mounted in a bearing in intermeshes with a gear on the shaft 81,

and rotates the latter first in one direction, and then in the opposite direction, the movement imparted to the bevel gear 77 being first to the extent of one hundred and eighty degrees in one direction, and then one hundred and eighty degrees in the same direction, as distinguished from the movement of the shaft 11 which rotates first in one direction, and then. in the o posite direction.

The hub of the beve pinion 82 is keyed to a clutch member 87, having clutch teeth engaging similar teeth formed in a clutch member 88 that is keyed to the shaft, and is held against the clutch 87 by aspring 89. The bevel pinion 83 is similarly mounted, and is arranged to be operated by a clutch member 90 held in clutching position by a spring 91. The ratchet teeth of the respective clutches, however, face in o posite directions, so that when the shaft 81 1s rotated in one direction, one clutch only will be operated, and one of the gears will rotate, while the other gear re mains idle and its clutch inoperative. When the shaft is rotated in the o posite direction, the first bevel gear and its 0 utch will remain inoperative, while the second bevel gear and its clutch are secured to the shaft and impart movement to the bevel gear 77.

To the inner end of the hollow shaft or hub 76 is rigidly secured an arm 93, that is provided at its outer end with a guiding box 94 for a stud 95, that is movable in the direction of its length, its inner end having a flat face for engagement with the lugs 75 of the feed or take up drum. The opposite end of the stud has an enlarged head 96, between which and the base of the pocket is arranged a helical compression spring 97, tending normally to force the stud 95 out of engagement with the lug 75, and to force the head of the stud into engagement with a stationary cam ring 98. The cam ring 98 has a central hub that is mounted on an extension of the bearing 78, and is revolubly'adjustable thereon, a flange 99 projecting from the hub being provided with arcuate slots 100 for the passage of securing bolts 101, by means of which the cam ring may be locked in adjusted position. The cam ring is provided with two shoulders 102 and 103, that are disposed at diametrically opposite points, and these shoulders are arranged substantially in 'alinement with two of the studs 75 of the feed or take up drum, the depth of the shoulders being such that when the head 96 of the stud passes over said shoulders, the inner end of the stud will move out of engagement with the lug 75 with which it has previously been engaged.

In the operation of this mechanism, the parts are so timed that the arm 93 carrying the stud 95, will stop at a point mid way between two of the lugs 75. At the beginning of a twisting operation, movement is transmitted to the bevel gear 77 through .the mechanism previously described, and the arm 93 is rotated to the extent of one-eighth of a revolution before it comes into engage ment with one of the studs 75, and during this eighth of a revolution the twisting operation is being carried on without any forward pull or feed of the cables, so that the latter will be tightly twisted behind the picket, which has been entered in the shed. After completing one-eighth of a revolution, the stud 95 will engage one of the lugs 75 and will continue in engagement therewith until ithas moved the stud 75 to an extent of ninety degrees, this distance being sufficient to take up a length of cable equal to the distance between two pickets, in the present instance twelve inches. The head 96 of the stud at this time moves over one of the shoulders 102 or 103 of the cam ring, and is moved outward by its spring 97 until the stud is free from the lug, thus stopping the feeding movement. The arm 93 continues to rotate to the extent of one-eighth of a revolution, again stopping at a point midway between two of the studs 75, and during this latter eighth part of a revolution, the twisting continues without any forward feed of the cables, so that the twisting in advance of a picket to be entered is tight, and is approximately the same as that at the beginning of the twisting operation, while between these two points, or during the interval of feeding the twisting is comparatively light. In this manner the twist is made very tight on both sides of each picket, and the latter will be firmly held in place, while at points between the pickets, the twist may be more open, so that there is no unnecessary strain on the wire, and a smaller quantity of wire may be employed in the manufacture of a fence of given length than where a tight twist is made throughout the whole length of the cables.

The winding drum 1 1 0 is mounted on a shaft 13, and said drum is held between two disks 1 11, both of which are bolted or otherwise secured to the drum. One end of the shaft passes through a bearing 113 having a cap member 114 that is hinged at one side to the lower 1 bearing block, the opposite side of the cap carrying a notched lug 115 which receives the upper end of a bolt 116 that is ivoted on a pin 117 carried by the lower earing block. The upper end of this bolt is threaded for the reception of a nut 118 which may be tightened in order to hold the shaft 13 by friction in any position to which'it is turned. The bearing is further of such nature that the cap member may be readily loosened and swung back to permit the removal of the shafts, the roll, and the completed fence wound thereon.

At that end of the winding drum opposite the bearing 113 is arranged a pair of bearings 120 for the reception of a short hollow shaft 121 on which is mounted a pulley 122 that is constantly driven by a belt from any suitable source of power, the pulley being so mounted as to slip on the shaft when sufficient frictional resistance is offered to rotation of said shaft. Extending through the hollow shaft 121 is a cylindrical pin 121 arranged in aline ment with the shaft 13 and this in extends into a central opening formed in t e adjacent disk 111 in order to form a support for the end of the drum. 1 The inner end of the hollow shaft 121 carries an arm 122 from which projects a lug 123 arrangedito enter a notch 124 formed in the adjacent disk 111, the lug serving as a means for transmitting movement to the winding drum, so that the winding drum is held tight at all times, and always takes up any of the complete fencing which may pass the feed or take up roll. The slip of the pulley 122, however, is so regulated that it cannot pull the complete fencing over the feed roller, and turn said feed roller, the latter being held and constituting the sole means of insuring the proper step by step feed of the cables during the twisting operation. The Winding drum, however, serves to take up the cable as fast as it is fed, and holds the winding drum from backward movement during the latter portion of the twisting operation, that is to say, after the stud 95 has moved from engagement with the winding drum lug 75.

With an apparatus constructed in accordance with this invention, a wire fence may be manufactured rapidly and economically, and the twisting o eration is such that the picket members will e firmly secured in place without waste of wire.

In Figs. 17 and 18 is illustrated a modified construction of feeding mechanism. In this case the feed drum has a smooth periphery and serves merely as a guiding roller. The shaft 12 carries a sprocket wheel 140 which is connected to a sprocket wheel 141 by a link belt 142. The sprocket wheel 141 is carried by a transversely disposed shaft 143 which receives intermittent rotative movement in the direction indicated by the arrow in Fig. 17. At the opposite ends of the shaft 143 are crank disks 144 having wrist pins 145 which are connected by links 146 to the opposite ends of a cross bar 147 that is supported on the side rails of the machine. To the lower face of the cross bar 147 are attached feeding fingers 148 that are arranged to engage with the transverse or weft wires at points on opposite sides of the longitudinal strands.

When the shaft 143 is rotated from the position shown in Fig. 17 and travels through an arc of 90 degrees, the twisters will be actuated, but the wires will not be fed. During this movement, the feeding fingers 148 will ride over the next adjacent picket or cross wire to the rear of the feed bar, and will be in position to engage said picket or cross wire during the time the shaft and crank disks make a further movement to the extent of one hundred and eighty degrees. During the final movement of ninety degrees, the wire is being twisted, so that during one half of the revolution of the crank disks the wires will be fed forward, and during the remaining half the feed bar will be retracted to engage another cross Wire, the twisting operation being accomplished during the backward movement of the feed bar.
