To all whom it may. concern: Y

Beit known that I, J OI-IN L. CLAUDIN, a; citizen of the United States, residing ati Mortomin the county of Tazewell and State: of Illinois, have invented, certain; new and} useful Improvements in Wire-Fence Ma chines; and I do hereby declare that the following is. a: full, clear, and exact description of the invention, which will enable others; skilled in thefart to which it appertains to make, and use the same.

This invention has reference to machines for the making of wire fence fabric and has; for its object a machine for the continuous manufacture of such fabric, as compared/to machines which have an intermittent movement,ithat is, where-a certain amount of fabnic is intertwisted and the: twisting devices; stopped, during the pulling out of the fabric,

The machine is applicable for the manufacture of wire fencing substantially similar; to. that shown in. my application for patent which maybe manufactured are many andi by reference to the above, application, I do not intend to limit myself to, that particular form, but cite it to show one of the styles which may be made by the machine.

The invention has for its further object, a revoluble frame or drum, consisting of a shaft on which. is mounted a series of disks the. peripheries of which are providedwith a seriesof flat faces. The disks are secured: on the shaft through a spline and groove connection to, adapt the said, disks to be laterally adjustable, and on the flat faces thereof are, detachahly secured. twister sections.

A; further object of the inwention is a revolfuble. frame comprising. a shaft and a series of disks supporting a series of'twister sections mounted in detachablejournals which are secured to fiat faces forming the periphery of the disks, and in, the provision of reciprocally disposed rack-bars movable longitudinally across the peripheral faces of the disks and adapted to. intermesh with the twister sections; and the provision of means for intermittingly reciprocating such rack-bars for the purpose of rotating the twisting devices intermittingly during the continued. rotation: of the shaft,

A further object ofthe invention is in contwisting devices, The adjustment of such disks 1s for the purpose of graduating the distance between, themeshes to facilitate in using one machine. for making fences of varying widths or helghts. The construction of a machine whereln: are provided two "sets of disks, carrying twisters, is designed to manufacture two rolls of fence at one operation of the machine, and with the disks being adjustable there may be manufactured I at oneoperation of the machine, two rolls of fence which may vary lIl helght, the means for operating the twisting devices carried by one series of CllSkS servmg the purpose to actuate the twisting devices of the second series and simultaneous with the actuation bearing Serial Number 202,164, dated Apr. 8, 1994.. However, the styles of fencing of the first mentioned series.

The mventlon has for lts further-object a rotating frame comprising a shaft on which ed; to bereciprocated and intermeshing with the twister sections upon each succeeding head, andv also in the provision of a series of longitudinally movable rack-bars, one for ieach of the rows of twisters and engaging the twisters of each row. Also in; the provision of means attached to each of said bars, adapted during the continued rotation oftheframe to engage and follow the face of a 0am, to facilitate in reciprocating the rack-bars in opposite directions and there by impart movement to the twisters.

The invention has for its further object a revoluble support, twisting devices mounted in circumferential and longitudinal rows on said support; a series of pivoted shifting members, and means for osclllatlng all of the members simultaneously; a revoluble frame supporting a series of reciprocally disposed devlces havlng a predetermlned movement and adapted to cooperate with the shifting members to facilitate in guiding and holding strand wires after the same have been shifted and for the purpose of retaining them in position to be engaged by the twisting devices as they move into posltion and to permit the shifting devices to be moved in an opposite direction and in.ad- Vance of the guiding means on the revolving frame. And the invention consists of means for oscillating the shifting members and in the provision of suitable devices for actuating the guides of the revoluble frame.

The invention comprises in addition, certain details of construction to be hereinafter more fully described, and illustrated in the accompanying drawings which form a part of this specification, in which:

Figure 1 is a greatly reduced front elevation of a machine embodying my improvements; Fig. 2 is an elevation from one side of the machine as shown in'Fig. 1 and somewhat enlarged over said figure; Fig. 3 is a longitudinal section, of about the same scale as that shown in Fig. 2, of the revoluble heads,-the means for reciprocating the rackbars to actuate the twisters and illustrating the guiding devicesand shifters. The gearing for actuating the shaft supporting the heads and the devices for actuating the guides and shifters have been omitted; Fig. 4 is a cross section through the revoluble frame and is taken at one end of a casing or cylindrical member in which is arranged the helical cam by means of which the rack-bars are reciprocated; Fig. 5 is a cross section through the revoluble frame supporting the reciprocating wire guides, also showing its relative position in side elevation with reference to the twisters on the revoluble frame, and the wire shifting members; Fig. dis a side elevation of a portion of the revoluble frame supporting the reciprocating wire guides, one of said guides being shown; Fig. 7 shows an enlarged side elevation of a head or disk and the arrangement of the fiat faces in its periphery, and showing the man ner of supporting the twisting devices in the detachable journals. For the purpose of illustration, only two sets of twisting devices have been shown; Fig. 8 is a cross section on the line mw of Fig. 7 Fig. 9 is a cross section on an enlarged scale, showing the journals which support the twisters,

also showing a twister in cross section and guard plates attached to the journals to retain the wires to their centers; Fig. 10 is an elevation looking at one of the faces of the.

journals shown in Fig. 9; Fig. 11 is a detail in cross section and enlarged, showing means which engages the helical cam and causes the reciprocating of the rack-bars, also showing the manner of connecting this means to the rack-bars.

The machine consists of a shaft 1, disposed horizontally and journaled at its opposite ends in substantially duplicate frame parts 2, the frame parts being connected and braced by the braces 3, which also serve a further purpose.

On the shaft 1, which is one of the essential elements of a revoluble frame or drum, is carried a series of heads or disks 4, arranged as shown in Figs. 1 and 3 in two sets. There is. no limitation placed upon this arrangement, as the heads may be disposed in one or more sets, and there may be as many in a set as is desired. The two sets of heads are for the purpose of utilizing the operative parts of one machine to actuate the two sets of heads for the manufacture of two distinct rolls of fence, which may or may not be of the same height, as will become apparent. The heads are locked relative to the rotation of the shaft by means of a spline and groove connection, and adjacent heads or disks 4 are positioned on the shaft 1, relative to each other and retained in such a position or adjusted by means of two or more longitudinally disposed thread bars 5, which pass through the entire series of heads or disks 4, and openings 6 in the bodies thereof. .Upon the thread bars 5- and disposed adjacent to the opposite faces of each head are the adjusting and lock nuts 7. Thus it will be seen, that the position of a head or disk 4 or aseries of heads may be adjusted longitudinally or laterally on the shaft 1, by adjusting the position of the nuts 7, thereby changing the position of any one or all of the heads, and retaining them in such adjusted position or positions. The same arrangement for adjusting the heads may apply, to one head, a series of heads, or

a series arranged in two sets, as shown in the drawings.

The peripheries of the heads or disks 4, are arranged with a series of flat faces 8, and may be in number to suit the need of the machine. Detachably attached to each of the flat faces 8 of the heads 4 are a pair of brackets 9, which by the machine bolts 10 are secured to the heads, and adapt the same to be quickly and easily removed. Each bracket 9 forms a bearing for opposite hub portions of a twister 12 which is journaled in the brackets 9. The twisters, each comprise the half sections 13 having toothed peripheries and slotted body and hub portions, and the brackets 9 having the wire grooves or slotted portions 14, extending down into their bodies to a point approximately the center of the twisters; and the sections 18 are connected by inserting the slotted plate or disk 15 between them, the slotin the plate 15 being of such a contour as to form a wedge to clamp a wire or wires inserted into the slots. To the outside faces of each of the brackets is attached a guard plate. To the front bracket is attached a subs-enem angular plate 16, Tetalnetl inposition by the machine bolt 10, and'that portion of "the plate adjacent to the slot 14 of the bracket is slotted as at 17 to correspond thereto.

front and removed a short distance from the slot in the bracket and twister. The stud ers. The rack-bars are in number to correspond to the number of twisters on a head l, and reciprocate across the flat faces 8 there-' of. The disposition of the brackets 9 and the twisters'journaled therein is such as to form a groove or channel for the carry ing of the rack-bars and guide the same in their movement as they intermesh with the toothed portions of said twisters (see Figs:

3, 8 and 9). During the rotation of the shaft 1 and the heads at and at a given point in the movement thereof, the rack-bars are successively actuated or reciprocated which is for the purpose-of imparting an intermittent rotation to the twister-s. By reference to Figs. 1 and 3, itwill be noted that the movement of the bars 21 is from right to' left, and during this movement it is adapted to intertwist any wires which may be in the twisters; and when a twist has been formed or a sufficient number of turns imparted to the twisters, the bars have a reverse move} ment imparted to them which returns the twisters to their original positions. During the rotation of the frame, the twisters in each succeeding row are brought into a position with their slots uppermost to receive wires which are intended to be intertwisted, and upon the depositing of the wires, devices which will be described are brought into play to reciprocate the rack-bars and rotate the twisters. At the finish of the twist, the twisters are in position with their slots pointing downwardly and this permits the removal of the twisted fabric, when the rack-bars are reversed to return the twisters to their receiving positions.

Disposed between each set of heads or disks 4, or at the end of one set of heads if making a single roll of fencing, is shown a drum or cylindrical member 22, which is supported on the beams 3, and retained in a fixed position on said beams by means of the straps 23 and the bolts 24, which pass through the straps and are screwed intothe wall of the drum, see Figs. 3 and 4. 1

Attached to the inner face ofthe drum 22 The guard plate which is attached to the rear bracket is indicated as 18 and has an extension 19 which is provided with a shortpin or stud 20 extending up in and disposed circumferenti ally is a "helically disposed cam ring formed in two sections and 26, and the ends thereof overlapping. The upper end of the section 25 is placed on the inner face-ofthe drum, upon the right hand side thereof, looking at the drum from the front, approximately above the shaft 1,

andcarried forwardly and around the inner face of the drum, terminates at the lower left hand side of said drum. The section 26 begins short of the terminus of the lower section 25, and together "therewith forms a short channel '27.

On the rack-bars 21 is secured the sleeve 29. The manner of securing is by means of the toothed plate 30 having portions engaging the sleeve 29, and teeth which engage the teeth-of the rack-bars; there is also provided'the filling plate 31 between the lower "face of the rack-bar and the sleeve, and a bolt 32 is passed through the lower portion of the sleeve andengages the plate 31, and by this means secures the sleeve in a "fixed position on the bar 21. To the upper face of the sleeve 29 is journaled a roller 33;

these rollers are adapted to enter the channel 27 formed by the sect- ions 25 and 26, and

during the rotation of the shaft and heads the rollers willbe caused'to follow adjacentto the left face ofthe section 25 and draw the rack-bars to the left and at the lower end of the section 25 the rollers will enter the channel 28 and engaging the right wall of the section 26, will follow adjacent thereto and reverse the movement of the rack-bars until the said rollers again enter the channel 27.

It is intended that the curve of the section 25 at the start shall be abrupt to insure guide and brace for the sleeve 29 during the reciprocation thereof. The disks are also provided with openings 37 through which pass the-thread bars 5.

The power device for actuating the shaft 1, is through the shaft 38 which receives its movement through a belt and pulley connected to some suitable source of power. On one end of the shaft 38 is carried the pinion 39 intermeshing with a gear 40 on a counter shaft 4:1. Power is imparted fromuse a pinion 42 on the shaft 41 to a gear wheel 43 on the shaft 1.

As intimated in the preamble of this speci fication, there are provided shifting and guiding devices for controlling the feeding in of wires to the revolving frame and the twisters thereof. One of such devices shift-s the mesh wire to adjacent horizontal strands as they appear on Fig. 1, and in the application for fence patent referred to, and the other device acts as a guide and retainer to hold the wires in position preparatory to the twisting and during the interval when the mesh wires are being shifted to adjacent longitudinal strands. 44 denotes a longitudinally disposed shaft, its opposite ends journaled in standards 45, supported by the frame 2. On said shaft 44, are carried two pairs of disks, or four heads 46, which comprise the opposite end supports of a revoluble frame. The frame further comprises a series of plates 47 their opposite ends secured to the heads 46. The plates 47 have the flanged walls 48 forming an opening channel-way 49. And the position of each of the revoluble guides is above each of the sets of heads 4, and in their rotation they are so timed as to have the channel faces of the plates 47 coincide with the succeeding rows of twister-s as they are moved into position, for example see Fig. 5. Reciprocally carried by the flanged walls 48, is a bar 50, whose opposite ends are slotted and a bolt 51 passed therethrough and secured in the walls 48. Alternate sets of bars are adapted to be moved in opposite directions and returned. The method of moving the bars 50 is by means of rods 52 which pass through the heads 46, and to the rods 52 are attached the arms 53 whose opposite ends pass up upon the outside of the plates 47 and are secured to the bars 50. On opposite ends of the shaft 44 are carried cams 54 and 55. The opposite cams are adapted to actuate alternate rods 52, the alternate rods being of length and protruding beyond the end of their respective frames sufficient to engage and travel over the surface of said cams as their frames are revolved. To each of the arms 53 is connected one end of a retaining spring 56, whose opposite ends are attached to a head 46. The arrangement of alternate springs is to hold the end of their respective rods 52 against its cam and when said rod has moved off of the irregular face of the cam the spring returns the same to its position; in this way, as the guiding frames are revolved through the actuation of the shaft 44. as the channel faces 49 of the plates come coincident with a row of twisters, the rod 52 controlling the movement of the bars 50 will be shifted by the cam. On each bar 50 is a series of fingers 57, which protrude beyond the end of the bar, the bar being slotted as at 58, and bolts 59 for retaining they will act synchronously with the oleposit of the wire or wires by the shifter and be in position and doing their work when the shifter moves again to adjacent wires. The fingers 57 are adjustable on their sup ports to place them in position to receive the wires and to account for wear.

The shifting devices referred to comprise a cam wheel 60 carried on one end of the shaft 44, which is provided with the sinuous formed cam-race 61. suitable length, its lower end pivoted at 63 to a frame part 3 and to its upper free end is adjustably attached the end of a shifting bar or rod 64; to adapt the lever 62 to have an adjustable connection with the bar 64, the lever is provided with a series of bolt holes 65, and a bolt 66 serves to attach the lever and bar, as is apparent. To the body of the lever is attached a roller 67 which is adapted to travel in the cam-race 61 of the wheel 60. Thus it Will be seen, during the rotation of the shaft 44, the sinuous portion of the cam-race 61 will cause the lever to be alternately shifted in opposite directions, imparting a corresponding movement to the bar 64.

68 denote a series of oscillatory arms or fingers, arranged in two sets, one set for each set of twister carrying heads and the same are pivoted at 69 to a cross-head or frame support 70, the opposite ends of which support are attached to the frames 45. The upper ends of the arms are pivotally attached to the bar or rod 64, and the lower ends have pivoted or swiveled thereto, short studs or wire guides 71, through which mesh wires are passed as they are fed to the twisters.

The horizontal strand wires may be fed to the twister heads on a line with the axial centers of said twist-ers when in their receiving positions; however, the selvage strands in this instance are fed from above. The mesh wires, or the wires which are intertwisted with and shifted to adjacent strands, are passed down through the guides 71 of the arms 68, and around the rotary guiding and retaining frame, as seen in Figs. 1 and 5, and from thence into the twisters and following the contour of the twisting frame, being directed as a finished fabric to some suitable wrapping device, disposed either in front or in the rear of the twisting frame. The manner of feeding 62 denotes a lever of in the mesh wires and by giving to the same,

the reversebends as appear in the figures,

gives suflicient elasticity to the wires to,

permit the same to be interwoven without taking up all the spring in such wires, necesa sary toadmit of the fabric having the expanding and contractmg qualities due a woven fabric.

The shifting and guiding devices are so- The manner of driving the shaft 44, upon,

which is carried the revoluble guide frame, is by means of the gear wheel 72 on one end of shaft 44, intermeshing with an idler gear 73i on the stud 74;; which in turn intermeshes with a; pinion 75 on, the shaft 41 this latter shaft receiving its power in the manner heretofore state made and modifications andQequivalentsresorted to. without departing; from the spirit and scope of the invention herein.
