Application filed March 24,. 192%, Serial No. 46,286. Renewed May 29, 1924.

This invention has reference to wire fence machines, and particularly: to fence machlnes for making farm or poultry fences compris- Ill ing longitudinal line or strand wires and vertical stay or picket wires, the latter pref erably including short sections of stays severed from stay-feed-wires, their meeting ends intertwisted or intercoiled about the intermediate line wires, whereas the upper and lower ends-of the top and bottom stay-sec tions are coiled or wrapped around the mar-' ginal or selvage line wires.

The invention has for one of its objects to provide sets or series of ,depressors for the. stay sections tomove the'same into position to. be coiled or wrapped by -the coiling or wrapping spindles on the line-wires, one

' 'setor series of depressors also acti'n as cutters for severing the stay-sections rom the stay-feed-wires.

The invention has for a further object to provide an improved feeding means for the stay-feed-wires, whereby shorter or longer lengths of wires may be fed from which the top and bottom sections of stays are provided, as the height of fence to be'made is changed, it being understood that different heights of fence are made onthe same machine and the top and bottom sections of stays re uire more wirefor the wraps on the margina or selvage wires, than isrequired on the intermediate line wires.

Other and various objects will more fully appear in the following description.

That the invention may be more fully un derstood, reference is had'to the accompanying drawings, forming a part of the description, illustrating a-preferred embodiment of the invention, in which Fig. 1 is a side elevatiomof the machine,

Fig. 18 is'an elevation of a section of a fence such as made on the machine, and Fig. 19 is an edge view 0 Fig. 18. Like characters of refere ce denote cor responding parts thruout the figures.

Referring to the drawings, what I term' the bed of the machine is designated 1, supportedon end standards 2 connectedby a base frame 3 and to rearwardly extended frames 4, from which, at suitable points rise the uprights 5.

Before entering into a description of the parts or elements constituting'the invention herein, reference will be made to parts or mechanisms common to machines of this character and which are essential in so far as they go to make up a complete machine.

The pull out and spacer for the line wires comprises the oscillatory bars or beams 6 pivotally connected at 7 to the uprights 5, and said bars or beams at their forward ends are connected by a roller 8 over which the completed fence or fabric is carried. To said bars or beams 6 are pivotally connected s re con tr t on a d and c mpha a up the fence.

large gear Wheel 15 meshing with a smaller gear wheel 15 on a shaft 16 carrying a roller 17. The completed fence or fabric passing over the roller 8 also passes around the roller 17 and around the clamp 14 and down and around any suitable wrapper on a shaft 18 to which is connected a large pulley wheel 19 driven by a belt 20 from a pulley wheel 21 on the shaft 16. The belt 20 is held taut by an idler or tightener pulley 22 journaled on a pivoted arm 23 adapt ed to be moved into operative and inoperative positions by the toggledever 24. In the position ofthe pulley 22 the belt 20 is taut and the wrapper is being, revolved to roll By swinging the pulley 22 out and away from the belt 20 the latter is inoperative although moving allowin the attendant to revolve the pulley 19 by hand to manipulate the wrapper and remove a roll of finished fence or fabric when necessary.

The driving shaft designated 25, extends lengthwise under the bed 1 and has secured thereto a plurality of preferably spiral gear wheels 26, spaced at suitable distances from each other, corresponding to the distances oft-he line wires A from each other, said wires beingcloser to each other at the bottom'of the fence and farther apart at the top of the fence, as is understood in the' practical manufacture of fencing. This shaft, when the machine is in operation rotates continuously. On one end of said shaft is secured a pulley wheel 27 driven by a belt 28 deriving its power from any suitable source. Also on said shaft is-carried a sprocket wheel 29 operating a sprocket chain 30for driving a sprocket wheel 31 and a timing shaft 32 to which it'is connected, and said timing shaft also carries another sprocket wheel 33 driving a sprocket chain 34 which actuates a sprocket wheel 35 connected to the shaft 16, previously referred to.

36 designates ceiling or wrapping spindles journaled in an upright position in the bed 1, one for each line wire A. Only five such spindles are shown in the drawing, the tWo outside receiving the marginal or selvage wires and the three intermediates receiving the intermediate line Wires. There may be as many such spindles as desired, as it is' understood fences are made in varying heights and the spindles need only be multiplied to give whatever height fence is desired. Such spindles are also spaced apart whatever distances may be desired. In practice the spindles are closer together for the bottom Wires of the fence than at the top of the fence and at graduated distances therebetween. Each spindle on its lower end has connected thereto a spiral gear wheel 37 meshing with a spiral gear wheel 2 on t e d i ng haf o that hen the latter is in operation the spindles are being continuously rotated. On the upper end of each spindle 36 is provided wire engaging elements 38 located on either side of an opening extending longitudinally thru the spindles for the passage of the line wires A. buch elements 38 may be rollers, pins or other devices suitable for wrapping the stay-sections around the line wires, when said stay-sections are depressed on to .the spindles between the elements 38 and the line wire A, as shown in Figs. 11 to 16, both inclusive. I'

Extending longitudinally of the bed 1 are rock- shafts 39 and 40 which are journaled in bearings 41 secured to the top of the bed at opposite ends thereof. These rock-shafts may be termed depressor shaft-s, and'the shaft 40 designated a depressor and cutter shaft, as it functions both as a depressor and as a cutter shaft. To one end of the said shafts 39 and 40 are secured intermeshing segment racks 42 and 43, the former having an arm 44 to which is pivotally connected a bar 45 also pivotally connected to a second bar 46 having a roller 47 riding on the periphery of a cam 48 carried on the timing shaft 32, and said bar 46 is pivotally connected at 49 to a part of the machine frame, see Fig. 10. To yieldingly hold the bar 46 with the roller 47 in contact with the cam 48 a spring.50 is shown connecting the arm 44 and said bar 46.

On the rock- shafts 39 and 40 are suitably carried bracket-arms 51 and 52, the former carrying depressor-bars 53 and the latter carrying combined depressor and cutter bars 54, each bar having a notched end 55 adapted to provide a seat for the stay-feed-wire B as the depressors are moved downwardly to'engage and press the severed stay-sections onto the spindles 36. The stay-feed-wires B are fed into the machine by a plurality of sets of feed rollers; each set including a grooved roller'56 secured on an operating shaft 57 and a comparatively smaller and superimposed coacting roller 58. These last mentioned rollers are each journaled in supports 59'suspended by rods 60 and 61 adjustably connected to the machine frame, said supports 59 being preferably pivotally connected to the rods 60 while springs 62 on the rods 61 tend to yieldingly hold the supports 59 with the rollers58 in coacting relation with the rollers 57 between which and the rollers 58 the stay-feed-wires are fed, see Fig. 4. The successive'i'ollers 56 are'each larger in diameter than the preceding roller.

see Fig. 3, which, as will be understood is to provide for feeding variable lengths of staysections, which as previously stated are shorter at the lower end of the fence or fabric, see Figs. 7 and 18, than they are at the top of the fence.

In Figs. 3 and 17 I have shown one of the grooved rpllers 56 with two annular grooves 56 and 56", thelatter of greater diameter than the former. The explanation for this is as follows :In machines provided with more than seven sets of feed rollers 56 and 58 provision is made for manufacturing differentheights of fence, by cutting out certain of the sets of feed rollers. When changing the'height of fence provision must be made to feed the 'extra length of stay sections for the top of the staysv or ipickets to be wrapped or coiled around thectbp selvage or marginal wire. The same provision could be made should it be found desirable to change the spacing between the line wires at the bottom of" the fence. Therefore, all the rollers 56 above the seventh" roller from. the

bottom of the fence are preferably double grooved rollers, as shown in Fig. 17 L Communicating with and leadingfrom each set.

. of rollers 56 and 58 are wire guiding tubes 63, all of which at theirdelivery ends' are supported in suitable elements 64 mounted on-the bed 1', see Figs. 7, 8 and 9. These elements are located between the spindles 36,

as shown, with one such element inj'front of the top spindle, see Fig. 7. Each element, with the exceptlon of the first one from the feed rollers isprovided with anoff-set 65 and together wltli a cap-plate66 provide a groove 67 thru which the stay-feed-wire B is fed, and said cap-plates secure in place the "preferably ball-clamps 68 yieldingly held 'in acting position by springs 69. At

the receiving ends of the elements 64 havin the clamps 68 the'groov'es 67 are provide with funnel shaped openings 70, see Figs. 11 to 16 to guide the wires into the grooves 67 after they leave the tubes 63 and cross the space between the elements 64 and over the top of the spindles-36, see Figs. 11 to 16 ,AS shown in Fig. 7 the front end of each stay-feed-wire B stops just short of an element 64 below the depressor 53 so that as the shafts 39 and 40 are rocked in their bear ings the depressors 53 engage with the for-' ward and free end of the feed-wire while the combined depressors' and cutters 54 pass down across the front face of the elements 64 and both sever the stay-sections from the,

feed-wire and depress the severed ends of said sections onto the coiling spindles. The alternate depressors acting to depress the forward and rear ends respectively of ad- -jace'nt stay'sections between the line wires and the coiling members 38, see Figs. 11 to 16, which-as the coilers arerevolved" inter wrap or inter-coil the ends of adjacent stay sectlons, as at C on the line wires, with the exception of the ends of the top and bottom sections which are coiled or wrapped singly about the top and bottom selvag'e or marginal wires of the fence. The ball clamps 68 hold the stay-feed-wireslin the grooves 67 during the coiling operations, but yield to -the upward movement ofthe fabric or fence when moved by thepull-out frame 6 which, as' 'understood, advances the fabric the distance it is desired to place the stays,

six, nine, twelve inches or other distances apart, depending on the spacing desired.

The pull-out is actuated from the timing shaft 32, the cams 13for actuating the levers bracket and at its upper. end in aguide, 76. .The upper partof thebar 74 is formed. or provided with a rack-bar 77 having ameshing relation with, a. gear wheel 78 loosely 63 1116d 011 the operating shaft 57. Secured to said shaft adjacent said gear wheel is a ratchet wheel 79, formed preferably withtwo teeth, see Fig. 5, andpivotally connected to the, side of the gear wheel 78 and -adapted to engage said teeth is a ratchet pawl 80 yieldingly held in contact with said.

ratchet wheel 'by a spring--81, ,in mannershownin Fig. It will" thus be, observed that as'the timin bar 74 will be moved u .7 and down. With each down stroke of sai bar the .gear wheel 78 is turned backwards moving the pawl 80 from-the position shown in Fig. 5 into a position to engage the disengaged ratchet shaft 32.. is rotated the tooth of the wheel 79, then on the up stroke 7 of said bar 74 and as the gear wheel 78 is turned forward, the pawl 80 will move the ratchet wheel79 and impart a partial rotation to the shaft 57 and the feed wheels 56, which, coac'ting with the feedwheels 58 will feed the stay-feed-wires B the distance required tofurnish or supply stock for the stay-sections D severad therefrom. v

The stay-feed-wires B are fed from reel-s or other carriers, not showmand the line w1res likewise arefed from reels, or other uidmg carriers,jnot shown, to and around rollers 100 located in the base oft e machine and up and thru thesspindles 36. With the present construction it is preferable to provide a pit E, see Fig. 2 for the bar 74 on its downstroke. a g

vIn the operation of the machine the driv v ing shaft 25 is'continuously rotated imparting a like'movement to the coiling spindles 36 thru the spiral gearing descrbed. To depress the stay-sections D onto the coilers between the coiling members. 38 and the line wires A. the de'pressors "must be timed in theirmovement relative to the coiling spin dles, likewise the feeding in of thestayfeed-wires B and the P11111011; forthe finished fence.
