Application filed January 31, 1916, Serial No. 75,345. Renewed March 14, 1918. Serial No. 222,508.

T 0 aZZ whom it may concern:

Be it known that l, VVILLIAM SUMMER,

a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois. have invented new and useful Improvements in FVire-lWorkin Machines, of which the following is a speclficatlon.

This invention has reference to certain new and useful improvements in wire workmachine as l have reference to and for pur-.

poses of illustration and disclosure I'have incorporated into this application certain of the parts or devices shown in said patent.

()ne of the objects of the present invention is to improve the clutch-controlled mechanism included in the feeding means for the stay feed wire.

A. further object of the invention is to provide a stay wire feeding mechanism for feeding alternately a long stay wire and a comparatively short stay wire whereby, a fence fabric may be manufactured having alternately arranged long stay wires extendin;- from. one selvage or marginal wire to the other selvage or marginal wire, and comparatively shorter stay wires extending from one selvage or marginal wire to a. certain intermediate strand or line wire of the fence fabric. A fence so constructed combines a field and hog fence in. the one fabric.

The invention has for a further object to connect the intersections of the stays and longitudinal strand wires by means of suitable wire ties the mechanism for feeding the tie wire stock from which said wire ties are severed including means for feeding the tie wire stock to a predetermined number of the intersections of each succeeding long and short stay wires included in the fence fabric, and other means for feeding tie-wire stock to a predetermined number ofthe intersections of only the long stay wires included in the fence fabric. In other words, the mechanism for feeding tie-wire stock to the intersections of the short stay wires will opcrate with the placing of not only the short stay wires across the fence fabric, but also with the placing of the long stay wires across said fabric and in timed relation thereto, while the mechanism for feeding tie-wire stock to the intersections of the long stay wires with a predetermined number of the longitudinal strand wires will operate only at the intervals of placing said long stay wires across said fence fabric, and in timed relation thereto.

Like characters of reference denote corresponding parts throughout the figures.

In my former Patent No. 1,093,578, to.

which reference has been made, a feature of the inventive idea was the intermittent clutch controlled feeding means actuated by mechanism, which, when it acted upon the stay feed wire, started said stay feed wire at a slow speed, gradually increasing until the momentum of the wire reached its maximum speed, and gradually decreasing until the complete stay length had been fed, the highest speed of the wire being attained at the point when one-half of the desired length of stay had been fed. This feature of invention is included in the pres ent improvements, or rather, the present improvements in the mechanism for feeding alternately long and short stays is included in the means for feeding the stay wire in the manner just previously stated, and'associated with said stay wire feeding means, is an improved mechanism for feeding tiewire stock from which the wire ties are severed, used for connecting the intersections of the stay and the strand wires.

In the drawings, I have shown my improved stay feed wire mechanism and tiewire stock feeding means applied to that type of wire fabricating machine employing die mechanism for clenching wire ties around the intersections of the stay wires with the intermittent longitudinal running or strand wires, and coilers for wrapping or winding the ends of the stays around the marginal or selvage wires, with the exception that the upper ends of the short stay wires are connected to a certain intermediate strand wire by wire ties the same as is used for connecting the intermediate body portions of the long and short stay wires with intermediate strand wires.

The machine is illustrated in a general way for the purpose of showing the application of my invention thereto, and reference may be had to the Sommer Patent No. 1,078,702, dated Nov. 18, 1913, for detailed views of the die mechanisms and coiling means such as is used in the machine herein disclosed. These details form no part of the invention herein, but merely cooperate in forming a complete fabricating machine.

It will become apparent that my improvements, as herein described and claimed, may be applied to fabricating machines other than the kind herein illustrated, and I do not wish to be confined to the application of the invention to a machine such as shown.

The framework of the machine comprises in part the base members 1, the uprights 2 supporting the table 3; the standards 4-, 5, and 6, and the cross piece 7. The parts designated 1, 2, 5 and 6 are duplicated upon opposite sides of the machine and on the part 1 is supported the platform 8 on which an operator may stand.

9 designates a drive shaft and 10 a timing shaft, both of which are suitably journaled in hearings on the uprights 2. The driving shaft 9 is adapted to receive its power from some suitable source, such as a line shaft or direct drive from a motor, and it in turn is adapted to operate the timing shaft 10 through gear wheel 11 on the timing shaft (see Fig. 3), which will mesh with a gear wheel on the timing shaft, not shown.

14 designates a crank shaft suitably journaled in the frame and on said crank shaft is a sprocket wheel 15 engaged by a sprocket chain 16 which is driven by a sprocket wheel 17 on the timing shaft 10, said sprocket chain passing over an idler 18 carried by the upright 4-. It will be observed that the driving shaft '9, when in operation, transmits motion to the timing shaft 10 and it in turn drives the crank shaft 14 through the sprocket chain 16 and

sprocket wheels

17 and 15, respectively.

19 designates a wrapper shaft journaled in suitable bearings at the rear end of the machine, and said wrapper shaft 19 is driven from the crank shaft 14 by means of a nae/res? nism, and as stated, reference'may be had to the Sommer Patent,- No. 1,078,702 for details of the preferred form of structure. The mechanism for feeding the tie-wire stock to the wire connecting mechanism is material, forms a part of the present in vention, and will be hereinafter more particularly described.

24tdesignates the end coilers, one for each of the selvage or marginal wires of the fence fabric, and associated with each of said coilors is a. cutting and depressing mechanism 25, although the stay feed wire feeding mechanism when properly adjusted for the feeding of the stay wires is such that the cutting mechanism at the far side of the machine from the in-feed of the stay feed wire is not necessary, and only the cutter mechanism at the in-feed side ofthe machine is necessary, whereby a stay length my be severed from the stay feed wire. The details of this cutting and depressing mechanism are clearly shown in the Sommer Patent No. 1,078,702. In operation,the cutting mechanism will sever a stay length C from the stayfeed wire B, and the depressing mechanism will depress the ends of the stay Wire 0 down onto the coilers 24 in position to be engaged by the pins of the coilers for wrapping or coiling the ends of the long stay wires around the selvage or marginal wires, and one end of the short stay wires around one of said selvage or marginal wires.

The strand wires A, which are fed from reels, spools or other suitable means, not shown, pass preferably around a roller 27 on a spindle 28 and up through suitable openings in the table 3. The wires Awhich serve as the marginal or selvage wires pass up through the coilers 24:, and the wires A, sewing as the intermediate running or strand wires, pass through the die mechanism 23, as shown in Fig. 3.

The stay feed wire B which may be fed from a bundle, spool, or in any suitable man ner, passes through the straightening rollers, referred to generally as 30, and thence between the intermittently driven

friction feed wheels

31 and 32, and leaving said feed wheels, passes through suitable guides adjacent to the cutter and depressor 25 across the coiler or spindle 24: and through the die mechanisms, as shown in Figs. 1 and 3. The said feed wire 13, as shown, passes between the friction feeding wheels. 31 and 3:2, which engage the wire to feed it endwise across the machine. These feeding wheels may be grooved to receive the wire B, or not, as may be desired. The feed wheel 31 is the driving wheel of the feed, and the wheel 32 is the driven wheel. In other words, when power is applied to the wheel 31, it will impart movement to the wheel 32 through the engagement of such wheels with the wire B which is frictionally held be tween the same. The wheel 31 is carried on a shaft 33 which has a relatively fixed position with reference to the shaft 34 on which the wheel 32 is carried, and the shaft 34: is journaled in a frame 35 fulcrumed at 36,

and spring means 37 engaging the forward end of the frame 35 yieldingly holds the wheel 32 in frictional engagement with the wheel 31; the object of which is, to allow the wheel 32 to move relatively to the wheel 31 to accommodate the various sizes of said feed wires B which it. may be desired to use in the fabric.

@n the shaft 33 carrying the wheel 31 is also carried a gear wheel 37, said gear wheel 37 and feed wheel 31 being suitably connected so that when movement is imparted to one, such movement wil-lbe concurrently and simultaneously imparted to the other. The gear wheel 37 meshes with a much larger clutch controlled gear wheel 38. The gear wheel 38 is of that construction, best seen in Figs. 1 and 4c, wherein said wheel has the internal circumferential friction clutch-engaging face 39, and said gear is further provided with the enlarged depending hub 4:0, said hub being journaled on a bushing 41 carried on a vertically disposed tubular casing 42 suitably carried by the upright 2, shown in Figs. 2 and 4-.

4.3 designates a tubular shaft which has a bearing in the vertical casing 4.2, see Fig. i, said casing 42 having the lower and upper inner bushings 4 1 and 45 in which the tubular shaft 43 has a bearing; said tubular shaft 43 having the plugtG at its lower end and the similar plug 47 at its upper end, which serve as hearings in which is carried and through which movesthe vertically movable stem 48, which at its upper end and above the bearing 4L7is secured in the hub 19 of the wheel 50 having the peripheral friction face 51 adapted to have a friction engaging relation with the clutch-engaging face 39 of the gear wheel 38. The rim and the hub of the wheel 50 are connected by the arms or spiders 52, two or more of which are provided with the tubular bosses 53 in which are secured rods or stems 54, for purposes to be explained. On the upper end of the tubular shaft 43, and within the gear wheel 38 and below the body portion of the wheel 50,

is a plate or disk-like member 55; said 3 plate or'dislr-like member being secured to vided with two or more bosses 56 in which I the lower ends of the rods or stems 54 are carried and movable, so that when said plate or disk-like member 55 is rotated through and by means of the tubular shaft 43, such movement will in turn be imparted to the wheel 50 through the connections between said wheel and said plate or disk-like member, described. When the wheel 50 is raised through the movement of the vertical stem 48, which said movement is very slight, it will in turn elevate the rods or stems 54, without disengaging said rods or stems from said plate or disk-like member 55. From the foregoing description, it will be observed, that if the stem 48 is raised, it will in turn elevate the wheel 50, disengaging the friction gripping surface on the rim of the wheel 50 from the frictional clutch engaging surface 39 of the gear wheel 38, bringing about an inoperative relation between said wheel 50 and said gear wheel 38. Upon the stem 48 being lowered, the wheel 50 will in turn be. lowered, moving the friction gripping surface 51 of said wheel 50 into impinging relation with the clutch gripping surface 39 of the gear wheel 38, whereby if the tubular shaft 43 is rotated, such rotative movement will be imparted to said gear wheel 38 through the wheel 50 and the plate or disk-like member 55. The wheel 50 is moved from friction clutch-engaging relation with the gear wheel 38 to its disengaged position, by the upward movement of stem 48, as just described, and when said stem 48 is raise'd,it is moved against the tension of a spring 57 carried on the upper end of rod 58, (see Figs. 2 and 4,) and disposed between washers 59, the lower of which bears against the hub of the wheel 50, and the upper of which is held in position by means of the nuts 60 on the end of the rod 58. This rod extends down into the vertically movable stem 48' a suitable distance and is secured to a transversely disposed stem 61 passing through slots 62 in the wall of the stem 48, and the'opposite ends of the stem 61 secured in the walls of the tubular shaft 43. Thus it will be seen that as the stem 48 is raised, it will contract the spring 57 and as soon as the means for raising the stem 58 is released to allow the stem to return to its lower or norgear wheel 38. v

The means for rotating the tubular shaft 43, as will be described, is such that said tubular shaft is rotated alternately, first, in

one direction and then in an op osite direction. When said tubular sha t is rotated in one direction the plate or disk-like member 55, the wheel 50, gear wheel 38 and the feed wheel 31 will rotate concurrently and simultaneously through and by means of the connections described; but when the said tubular shaft 43 is rotated in an opposite direction, the gear wheel 38 and the feed wheel 31 with which it is geared, are inoperative by reason of the separation of the clutch engaging faces 51 of the wheel 50 and 39 of the wheel 38 resulting from the raising of the stem 48, in manner described.

On the lower end of the tubular shaft 43 and below the casing 42 (see Fig. 4) is carried a gear wheel 63 and said gear wheel is in mesh with and adapted to be driven alternately in opposite directions by the rackbar 64. Said rack-bar is movable in the guide 65, coincident with the gear wheel 63 and at its inner end said rack-bar 64 is sooured to a slidable head 66 having, preferably, a dovetailed connection with and movable on a bar 67, (see Fig. 2), said bar 67 supported by a bracket 68 at one end secured to the part 1, and at its opposite v end secured upon an arm 69 attached to the upright 4. It is obvious that any movement which is imparted 'to the rack-bar 64 will be in turn imparted to the gear wheel 63 and the shaft 43 to which said gear wheel is attached. When the rack-bar 64 is moved forward, or in the direction indicated by the arrow in Fig. 2, the stem 48 is in its lowermost position, being in that position shown in Fig. '4, and the clutch engaging face 51 of the wheel 50 is in clutch engaged relation with the clutch engaging face 39 of the gear wheel 38 and said gear wheel will rotate concurrently and simultaneously with the wheel 50, the tubular shaft 43 and the gear wheel 63. Such movement will also be imparted to the gear 37 and in turn to the

feed wheels

31 and 32 for the purpose of projecting the stay feed wire B across the machine preparatory to the operation of the cutter and depressor 25 for severing a stay length C. When the rack-bar 64 is moved in an opposite direction to that just described, mechanism will be brought into play for elevating the stem 48, which will in turn raise the wheel 50 and by such movement separate the clutch engaging surface 51 on the wheel 50 from the clutch engaging surface 39 on the wheel 38, and stop the rotation of said gear wheel 38. The alternate forward movement of the rack-bar 64 and the operation of the gear wheel 63 is such that only sufficient movement will be imparted to the gear wheel 38, to rotate the

feed wheels

31 and 32 to feed the stay feed wire a sufficient distance for delivering long and short stays C of the proper length, and that immediately upon the gear wheel 38 as es? being stopped in its rotation, the cutter 25 will be operated to sever a short or a long stay length C from the stay feed wire B. The rack-bar actuating mechanism includes adjusting means, as will be described, for regulating the stroke of the rack-bar to insure the feeding of long and short stays of proper length.

Pivotally connected at with the slidable head or blook 66 is a pitman bar or rod 71 and said bar or rod has a pivotal connec' tion at 72 with a plate 73 slidably carried on a casting 7 f keyed on the crank shaft 14. The plate 73 has a substantial dovetail connection with the casting 7 4.: (see Fig. 11), and such connection while permitting of a slidable relation between said plate and said casting, holds the plate true during its movement back andforth on said casting. To provide for the pivotal connection between said pitman bar or rod 71 and the plate 73, said plate has a stem 75 projecting there from, formed with two shoulders 7 6 and 7 7 On said stem between the shoulder 76 and the body of the plate 7 3, is carried a collar 78 having a threaded stem 79, and on said stem 75 between the shoulders 7 6 and 77 is carried the end of the pitman bar or rod 71, whereby a pivotal relation is produced between said pitlnan bar or rod 71 and said plate 73. That ortion of the stem 75 between the shoulder 7 and the extreme outer end 75 of said stem is threaded as at 80 to receive a nut 81 for holding the collar 7 S and the end of the pitman bar or red 71 in operative connection with said stem. The casting 7a is formed with a hub or hearing portion 82, about which encircles a segment gear 83, said gear being stationary while the casting 74: is rotatable. This segment gear 83 is in juxtaposition to a cam plate 8-l, and said cam plate and said segment gear wheel 83 are bolted or otherwise suitably secured to the

standards

5 and 6. On the rear end portion of the casting 7 at and located on the outside face thereof is rotatably carried a plate 85, said plate having a hub 86. Journaled in said casting, and having a bearing in said hub 86 of the plate is a hub 87 of a gear wheel 88, said gear wheel and said plate 85 being connected so as to rotate together by means of the'bolt 89 passing through said plate 85 and gear wheel 88 and with a nut 90 secured on the end of said bolt, the plate 85 and the gear wheel 88 being suitably recessed to receive the head of the bolt and also the nut as best seen in Fig. 13. Secured to the rear face of said gear wheel 88, by bolts or other suitable means, a plate 91 having the friction bearing surfaces 92, (see Fig. 16). The gear wheel 88 is so disposed on the rear face of the casting 74: that during each complete rotation of the casting 74: with the crank shaft 14, the gear wheel 88 will intermitsilt tently engage with the teeth of the segment gear 83 and rotate the plate 85 one-half revolution. The engagement of the teeth of the. gear wheel 88 with the teeth of the segment gear wheel 83 will take place during onehalf revolution of said casting 74, and during the remainder of the complete revolution of said casting 7d, the friction bearing surfaces 9:2 on one side of plate 91 will enand ride on the cam surface of the plate 84;, holding the plate 85 in the position just previously moved by the intermeshing of the teeth on the gear wheel 88 with the teeth of the segment gear wheel 83. The gear wheel .88 is provided with diametrically disposed master teeth 93 to impart the initial movement to said gear wheel 88 and the plate 85, when said master teeth move into engagement with the first tooth of the seg ment gear 83.

The pitman bar or rod 71 which actuates the gear wheel 63 through the rack-bar 6d, is rcciprocated through the rotary movement imparted to the casting 7% by the rotation of the crank shaft i l, and the length ofthe stay wire C is determined by the position of the plate 73 and its stem 7 5 (to which is pivotally connected the pitman bar or rod 71) with respect to the axis of the crank shaft i lby means of which the plate 73 is rotated. In other words, the closer to the axis of the crank shaft let is carried or positioned the stem 75, the shorter will be the stroke of the rack-bar 6d, and the farther from the axis of the said crank shaft 14 is carried or positioned the stem 75, the greater the stroke of the raclebar 64-. A short stroke of the rack-bar 64: will produce a short stay wire C and a long stroke of the rack-bar 64 will produce a long stay wire C.

Tn my former Patent, No. 1,093,578, the pitman bar or red, to which is connected the rack-bar, is shown connected with a crank arm through and by means of which the pitmanbar or red is reciprocated, and said pitman bar or rod has an adjustable connection with said crank so as to shorten or lengthen the stroke of the pitman bar or rod and with it the rack-bar. The adjustment includedin such driving mechanism, in my former patent, was only for the purpose of regulating the length of the stay wire with each difierent type of fence to which the machine was adjusted. That is to say, all stay wires were of the. same length, reaching from one selvage or marginal wire to the other selvage -or marginal wire, and the only necessity for adjusting the stroke of the rack-bar would be in the event of a change in the height of the fence. In the present machine the stroke of the rack-bar must be changed with every other stay and this change must be done antomatically so that with each alternate stroke of the rack-bar a longand a short stay will be fed into the fabric. I accomplish the alternate feeding of a long and a shortstay wire by automatically changing the position of the plate 73 with its stem 75 on the casting 74 during each revolution of the crank shaft 14. That is to say, as the casting 74 is rotated with the crank shaft 14 to impart a reciprocal movement to the pitman rod or bar 71, the gear wheel 88 will mesh with the intermittent gear wheel 83, imparting a one-half turn to the plate 85 and through connections between said plate 85 and the plate 73, which I shall now describe, the position of the plate 7 3 with its stem 75 may be moved closer to or farther from the axis of the crank shaft 14 whereby a short stroke of the rack-bar 64 may be made for the purpose of feeding a short stay wire C, or a long stroke of the rack-bar 64 may be made for the purpose of feeding a long stay wire C.

Having a dovetailed connection with and slidably adjustable on the plate 85 is a head 94, said head formed with an extension 95 to .which is suitably connected one end of a threaded stem 96, the opposite end of said stem passing through a bearing plate 97 secured to the end of the plate 85. The end or the threaded stem 96 is squared as at 98,

- whereby by means of a suitable tool the threaded stem may be operated to adjust the position of the head 94 on the plate 85. Suitably connected with the head 94 is a threaded stem 99; and said stem 99 and the similar stem 79, previously referred to, have a threaded relation in a tubular nut 100, and on said threaded stem 99 is carried a tubular nut 101 serving to lock the position of the threaded stem 99 in the nut 100, and on the threaded stem 79 is a tubular nut 10:2 serving to lock the position of said threaded stem 79 in the tubular nut 100. In each of said

nuts

100, 101 and 102 suitable openings or perforations are provided for the insertion of a suitable tool for adjusting the threaded stems 79 and 99 relatively to each other to regulate the position of the plate 73 on the casting 74, and the position of the head 94 on the plate 85, such adjustment increasing or decreasing the length of the stay wire C, when necessary to insure the long stay wire reaching from one selvage or marginal wire of the fence to the other, or from one selvage or marginal wire to a certain intermediate strand wire of the fabric.

I will now describe the means for elevating or lifting the stem 48 to separate the clutch, engaging surface 51 of the wheel 50 from the clutch engaging surface 39 of the gear wheel 38 when the rack-bar 64 is moved in a direction opposite to that indicated by the arrow on the rack-bar (Fig. 2). On the cam shaft 10 (see Fig. 2), there is carried a wheel 103 having the engaging

surfaces

104 and 105, the latter acting as a cam surface and leading and merging into the surface 104 at points 106 and 107. Adapted to engage and roll upon the

surfaces

104 and 105 of wheel 103, is a roller 108 carried by an arm 109, which said arm is fulcrumed at 110 on a bracket 111. The arm 109 is formed with a neck 112 carrying a stem 113, which said stem is normally in axial alinement with the stem 48 operatively carried in the tubular shaft 43, and said stems 113 and 48, re spectively, are connected by a loose joint 114, (see Figs. 2 and 4). The object of such loose joint is to provide for moving the stem 48 when the arm 109 is operated on its pivot 110, and also to allow the shaft and stem to rotate without disturbing the actuating means for said stem. When the roller 108 is engaging and traveling upon the surface 104 of the wheel 103, the arm 109 is in a position permitting the stem 48 to assume its lowermost position, being that position shown in Fig. 4, where the clutch engaging surface 51 of the wheel 50 is in clutch engaging relation with the clutch surface 39 of the gear wheel 38. When said roller 108 is engaging and traveling upon the surface 105 of the wheel 103, the lower end of the arm 109 has been swung outwardly on its pivot 113, elevating the neck 112, and raisin the stem 48 to cause the wheel 50 to be raiser separating the clutch surface 51 of said wheel from the clutch engaging surface 39 of the gear wheel 38 and stopping the rotation of said gear wheel. When the rack-bar 64 is moved in the direction indicated by the arrow on said bar in Fig. 2, the roller 108 is riding on the surface 104 of the wheel 103 and the clutch engaging surface 51 of the wheel 50 is in clutch engaging relation with the clutch surface 39 of the gear wheel 38; immediately upon the rack-bar 64 reaching the limit of its forward stroke, whether it be for a short or a long stay, the off-set portion 106, where the surface 105 of the wheel 103 merges into the surface 104 of said wheel, engages with the roller 108, operating the arm 109 to elevate the stem 48 which will cause the wheel 50 to be raised, separating the clutch engaging surface 51 of said wheel 50 from the clutch engaging surface 39 of the gear wheel 38, and the parts will be held in this position until the rack-bar 64 is moved backward the limit of its stroke and is again ready to be moved forwardly, when the roller 108 will ride off of the surface 105 at the point 107 onto the surface 104, the arm 109 being oscillated through such movement and through the expansion of the spring 57 which was contracted during the separation of the clutch engaging surfaces as aforesaid, causing the stem 48 to be moved downwardly carrying with it the wheel 50, through the connections previously described, causing the clutch engaging surface 51 of the wheel 50 to enter into clutch engaging relation with the clutch engaging eeann? surface 39 of the gear wheel 38, when said gear wheel may be rotated through the driving connection between the tubular shaft 4:3 and the plate or disk-like member 55 with said wheel 50, previously described.

The surface of the wheel 103 is pref? erably formed by the arch-shaped wings and 116, (see Figs. 5 and 6,) which are adjustably attached to the rear face the wheel 103, so that the peripheral face of said sections may be brought together or moved apart, while yet at the same time extending or retracting the surface 1G5 for the purpose of adjusting or regulating the move? ment of the arm 109, to conform to the stroke of the racl=:bar64:, or to conform to the movement of any other parts of the mechanismwith which the same has a timed relation. 1 r i It will be understood from the foregoing description, that the timing shaftlO has a one to one relation with the crank shaft 14; that is to say, the timing shaft 10 is geared to make one revolution with each revolution of :the crank shaft 1 1, and vice versa, so that with each. stroke of the pitman bar or red 71 and the rack-bar 64,

whether the mechanism is feeding a long stay wire Cor a short stay wire G,the wheel 103'on said timing shaft 10 will operate in timed relation thereto to actuate the mechanism for separating the clutch engaging surfaces between wheel 50 and the gear wheel'38, and permit such parts to reengage at proper intervals of time to actuate the feedingllltZCllHJllSl'l'l forprqeotmg either a long stay wire C or a short stay wire C across the fence fabric. It is obvious that through the mechanism described for operating the pitinan bar or rod 71 from the crank shaft 14, that durlng the movementof said pltman bar or rod 71 and said rack-bar 6 1 to feed a long stay wire C, such parts will move relatively faster than they Wlll move during the feeding of a short stay wire (I, and

-\vl1e!;lie1' operating to feed a long stay wire between the wheel 50 and the gear wheel 38.

will be actua-tedso as to insure the separation of such clutch engaging surfaces after the feeding of each long and short .stay

wire C. p i

The long and short stay wires C where they intersect with the intermediate strand wires A of the fence fabric are connected thereto by. means ofstaple-like tie-members D. 'li'hose tie-members are first severed from tie-wire stock E, said tie-wire stock being intermittently fed to each ofthe intersections of the long and short stay wires F or a more detailed denism, reference may be had to the Solnmer Patent No. 1,078,702. 'However, by reference to Figs. 17 to the feeding mechanism for the tie-wire stock may be seen,

such as usedon "that side of the machine for feeding the tie-w1re stock from which the staple-like tie-wire sections are made for the upper portions of the long stay wires C, where they cross the upper series of 1n- BGIIDSClltttG strand wires A, (see Figs. 3and 21) and. with slight modifications the mechanism shown in Figs. 17 to 20 is used on the other side of the machine for feedlng the tie-wire stock from which the staplelike sections are severed used for connecting the lower portions of the long stay wires nally and in opposite directions, (see Figs.

8 andQl), but this arrangement in no wise affects the symmetry of the fence or its practicability.

Having reference to the tie-wire stock feedingmechanism for both sides of the machine, 117 designateiis a driving shaft on which carried a plurality of friction driva ing wheels 118. This shaft 117 is intermittently operated by means of a pawl 119 pivotally connected between plates 120 loosely carried on said shaft 117, and to said plates pivotally connected a member 121 which in turn has pivotally connected thereto a pitman bar or rod 192, and said pitman bar or rod is r ably connected to one end of a lever 123 fulcrunaed-at on the bracket G8,'and said lever at its opposite end carries a roller 125 ridnig against and adapted to I be'o tierated by the cain wheel 1% carried on theouterendof tne time shaft 10. Thus, SJl'th each revolutlon of the timing shaft 10,

the pitman bar or rod 122 will be reciprocated,causin;,2; the pawl 119 to engage with a teeth of a ratchet wheel 127 keyed or otherwise suitably secured on the drivingshaft 11? between. the'plates 120, and rotate said shaft to feed in the tieavire stoclrE. The feeding of the tie-wire stock E is accomplished through the feeding wheels 118 and a ser s of feeding wheels 128 which coiiperatc therewith, said l '--mentioned feeding wheels carried ona driven shaft 129 and internally geared thereto through the internal gears geared together by means of the intermeslring gears 132 and 133, best seen in Fig. 2.

r The feeding wheels 128 are adapted to be yieldingly forced into cooperative relation with the feeding wheels 118 for the purpose of feeding the tie-wire stock E, or one or more'of said feeding wheels 128 may be released and allowed to run loose when it is desired to cut out the feeding of any one or more of the tic-wire stock wires E. This is accomplished by rotating each feeding wheel 128 in a friction bearing block 136k, and engaging each bearing block is, a bar 135" which may becaused to hear more or less against the bearing'block 134, by means of the adjusting screw 136. The mecha 'nism which'l have just described for feeding the tie-wire stock is substantially the same for bothsides of the machine.

It is necessary, however,v to operate the driving shaft 117 on thel'eft hand side of the machine, looking at Fig. 3, when each long and'short stay wire has been fed across the fence fabric, because the tie-wire stock E fed by means of the feeding

rollers

118 and 128 on this side of the machine, is used to supply the tie-wire stock for the formation and attaching of staple-like tie-wire members for that portion of the long stay wires attached to the corresponding intermediate strand wires A to which the short stay wires are attached; whereas, the tie-wire stock fed by. the. feeding

rollers

118 and 128 on the opposite or right-hand side of the machine, looking at Fig. 3, is only fed when a long stay wire C has been fed across the fence fabric, and such tie-wire stock is used for supplying the wire from which the staplelike tie-wire members are severedused for connecting the upper portions of the stay wires C to the intermediate strand wires A across; which the short stay wires C do not extend, In other words, the driving shaft 117 is partially rotated with each alternate movement ofthe corresponding shaft 117 on the other side of the machine, and with every other rotation of the timing shaft 10. I accomplish this through the provision of an additional ratchet toothed wheel 137. This wheel is loosely carried on the driving shaft 107, and preferably upon an extension ofthe'ratchet toothed wheel 127, (see Fig. 20). Theratchet toothed wheel 137 is much larger in diameter than the ratchet 7 other toothof the ratchet toothed wheel 127 and such engagementwill occur when the pawl 119 enters a deep tooth 138 on the wheel 137, but when said pawl enters a shallow tooth on said ratchet wheel 137, itwill be held from engagement with a tooth on the wheel 127, although the pawl 119 may move and with it will move the ratchet toothed wheel 137 as will be understood. The pawl 119 for this side of the machine is provided with an extension 139 to permit it to have engagement with the teeth of the ratchet toothed wheel 137 (see Fig. 18). It is obvious, therefore, that with each alternatemovement of the pawl 119 having the extension 139, or when the pawl 119 engaging with a shallow tooth on the ratchet wheel 137, said pawl will not engage with a tooth on the ratchet wheel 127, and that no movement will be imparted to the driving shaft 117, although the ratchet wheel 137 will rotate thereon, but that when said pawl. 119 enters a deep tooth 138 of the wheel 137, said pawl will engage with a tooth on the ratchet wheel 127 and impart a partial rotation to the driving shaft 117 for feeding in the tie-wire stock E.

The ratchet toothed wheel 137 is secured to or forms a part of a sleeve 140, which is carried on the sleeve extension of the ratchet toothed wheel 127, and for yieldingly and frictionally holding said sleeve 14:0 and ratchet toothed wheel 137 in operative positionrelativcly to the ratchet toothed wheel 127, a threaded stem 111 is secured into the end of the shaft 117 and on said stem is carried a bearing plate 1-l2 adapted to engage the end of said sleeve 140, and said bearing plate 1&2 is adjustably and yieldingly held in this position by means of a spring 143 coiled about the stem 142, said spring hearing against the plate 1&2 and against looking and adjusting nuts 1 14.

The tire-wire stock E is fed to the machine from suitable reels or spools over a roller 1 15 and through tubes 146, which said tubes for a portion of their length extend transversely across the machine and then diagonally to the wire connecting mechanisms 23, as best seen in Fig. 3.

In Fig. 22 is represented a piece of fence fabric comprising ten longitudinal wires, two of which form'the outside marginal or selvage wires and the remainder of which comprise the intermediate strand wires. .1 standard field fence with ten longitudinal wires would constitute a ten bar forty-seven inch fence. This fence with the long and short stays would combine, as previously stated, a hog and a field fence, that portion of the fence connected by the short stay wires including six longitudinal wires corresponding to a six bar twenty inch fence. The figure illustrates the progressive order in which the short and long stays are attached and the manner of attaching the bill same, and the feeding in of the tie-wire stock from the opposite sides of the machine, and as shown, one short stay has been attached, a long stay .is in the act of being applied, together with the tie-wire stock fed to theintersections of said long stay and intermediate strand wires, and indotted lines is shown the successive step in feedingia short stay wire, after the feeding of each long stay wire.

',l"he end coilers through which the outside i'narginal or selvage wires of the fence pass, are driven from the timing shaft 10 by means of the. bevel gear wheel 1%? interineshing with the bevel gear pinions 148 on the lower ends of said coilers.

On the opposite ends of the timing shaft 10 are carried cam wheels 14:8 and engaging and riding on the surfaces of said cam wheels are rollers 150 carried by levers 151,

' fulcrumed at 124: on bracket 68, and to tlfe rear end of each of said levers 151 are pivotally connected bars or rods 152 for oper ating a pullout mechanism, not shown. The pull-out mechanism to which the bars or rods 152 are connected is substantially such a mechanism as is shown and described in the Sommer Patent 1,078,702, the same being adapted when moved to intermit tently advance or feed the strand wires A through the machine, and. adjusted to move said strand wires the distance at which it is desired to place the stay wires from each other to provide the proper spacing between the stay wires on the fabric.

In my former Patent No. 1,093,578, there is shown, described and claimed a mechanism for operating the rack-bar which would feed the stay wire, starting at a slow speed and increasing to the maximum speed, and slowing down to a complete stop, whereby a predetermined and given length of stay wire is fed, without any waste, thus avoiding the severing of short pieces from the stay wire C after the wire is fed. This is accomplished by the use of theparticular mechanism shown in that patent for driving the rack-bar from the crank shaft. The mechanism heresubstituted for driving the rackbar from the crank shaft will not ony permit of the feeding of the stay wires in the manner just stated, but is also adapted, as described, to alternately feed a long and a short stay, embodying in such mechanism the feeding of the stay wire, starting at a slow speed and increasing to the maximum speed and slowing down to a complete stop.
