Referring now more'particularly to the drawings, wherein the samereference characters are applied to the same parts .through out,the numeral 1 indicates a frame which carriedon legs 2. The frame comprises side "members .3 providing bearings for the shafts 4 carrying fi'veend and intermediate sprockets 5. The forward shaft 4' receives power from a suitable source (not shown) andv drives a shaft 6 through the medium of a chain drive 6. The shaft 6 carries power transmitting mechanism ofany suitable description such as gears 7 and 8, thegear 8 meshing with another gear (not shown); on the shaft 9 carr 'ing ,the finishin -reel 10 on which the fa ric is wound. bar 11 carries guide elements (not shown) for the selvages of the fabric to be wound on the finishing reel 10.1 A transverse frame member 13 intermediate the cross shafts-4c and arcar cross frame member 14 serve to connect and brace the'fsideframe parts 3.

V 7

Twisting meckanz'sm.-The sprocket chain consists of five sections cooperating with the five. sprockets 5 on each shaft 4. Each of a the outside sections comprises identical outer members 19 and inner members 20, pivoted to .one another by means'of-pins or rivets 20?,j'the inner elements 20 having projecting arms or lugs 21 to whichguide bars 22 are secured transversely of the'machine; Each intermediate chain section, of which there are three consists of adjacent staggered link elements-19 and 20, 'alsoconnected for relative pivotal movement by suitable rivets or pivot pins 20*, the outer of theelements 20 and 19 straddling the other or remaining inner elements 20. The right intermediate section of the chain has its inner link elements 20 rigidly secured by bolts 20 or the like to one series of guide bars'22, and the inner elements 20 of the left intermediate chain section are secured like-wise to the other and 'alternatefseries of guide bars 22. All of the eIementsQQfof.the-central section (not, shown) of the chain 15 are secured in like manner to the central portions of all of the guide bars 22. l

Twister holding plates 23 are secured on opposite sides of each guide bar 22, the plates 23 extending across the central portion of the machine and being substantially coextensive with the maximum width of.

fence or fabric to be manufactured. The plates 23 have registering vertical slots24: affording entry of the line or warp wires 25 and mesh or woof wires 26 of the fabric.-

Twisting wheels or twisters 27 are rotatably tively, for a urpose to appear later in the description. ach twist gear 27 meshes with and is rotatedby a rack 29 which extends transversely'fof the' machine and between the plates 23 and slides In a longitudinal groove 30in the upper part of each guide bar 22. The front plate 23 of each 16 twisting mechanism T is'provided wlth an opening 23" adapted to communicate with the slot 28 of the gear 27 at certain times during the operation of the twisting mechanism, to thereby afford a means through which chips and the like resulting from the twisting of the wires may escape. With this construction, jamming of the parts due to the presence of foreign matter is avoided.

Each rack 29 is actuated by a U-shaped member 31 which is slidably mounted on a guide bar 22 and which is secured to the rack 29 by suitable rivets or the like (not shown). A roller 32 is loosley mounted on each U-shaped member 31 and projects into one of the guideways 33, 34. One of these guideways is located near each side of the machine, as clearly seen in Figure 3, and each is formed by a pair of oppositely disosed bars which are secured to the top, ttom and curved end plates 16, 17 and 18 respectively. I

The guideways 33 and 34 reci rocate alternate racks simultaneously an in opposite directions, the right guideway 33 actuating the left set of racks 29 and the left guideway 34 operating the right set of racks 29. The inclined portions 36 and 37 of the guideways 33 and 34, respectively, are inclined in opposite directions. The guideways 33 and 34 are endless and it will be understood that the inclined portions 36 and 37 arranged beneath those shown in Figure 3 actuate the rollers 32 in a reverse direction to that just described and thus serve to bring the racks 29 back to their starting points and keep them thus until after the twisting wheels 27 receive the Wire at the rear of the machine for fabricating the netting. The continued travel of the chain 15 causes the racks 29 to be properly actuated by the guideways 33 and 34, a more detailed description of the twisting operation appearing later herein.

tion, arrangement is made for the formation of a fence or wire fabric of hexagon mesh, with or without the use of line wires. I shall first describe the invention when used in .65 connection with line wires and later in conregistering with the slots 24.

44 moshing with and driven F or the purpose of the present illustrain the opposite direction by .any suitable instrumentalities as gearing 50 nection with a fabric which does not include linewires. v v a In accordance with the illustrated arrangement,,the twisters 27 are spaced apart in accordance-with the size of mesh of the fabric to. bemade, the number of twisters 27 corresponding with the greatest desired number of meshes to be made. The line wires 25 are received from .a suitable source (not shown) -atflftheg'rearofthe machine as;

viewed ' in'Flgures 1, 3 and 14 and, after leaving various tensionin and guide rolls, pass through openings 38 in a guide bar 39 carried by the reinforcing frame member 14 adjacent the rear of the machine, the openings 38 beingarranged in the planes containing the twisters. r The line wires25 continue forward without change in direction, resting in and carried by the bottoms of the slots 24 and 28 of the twisting mechanisms T, and are then drawn up into the grooves 40 aligned therewith in the removing or pick-up roll 41, along with the mesh wires 26 when the netting is fabricated. The roll 41 is carried by a shaft 42 journalled in the brackets 43 of the machine. The shaft 42 carries a gear by the gear 7 on the power transmitting shaft 6.

Transfer of the mesh waver-The mesh wires 26 lead from a suitable source (not shown) at the rear of the machine as seen in Figures 1, 3 and 4, pass thru openings 45 which are spaced apart substantially as in the case of the openings 38 for the-line wires 25, but staggered with respect thereto as seen in Figures 3 and 14. The openings 45 are provided in a guide bar 46 extending transversely of the machine and pivotally adjustable to various elevations by means of bolts 47 or the like. The adjacent openings 45 are spaced apart, substantially half the distance between adjacent twisting gears or twisters 27, that is, substantially one half the width of mesh to be fabricated, and in the event line wires are used, these will be spaced apart the same distance. The clearance slots 24 for the line wires 25 in the twisting mechanisms T are spaced from the slots 24 the same distance, and it will be clear from the foregoing that the openings 45 are staggered relative to said slots 24 and 24. The adjustment of the guide bar 46 is provided in order that the guide barmay be properly positioned to insure proper engagement and distribution or shifting of the mesh wires by the cams preceding entry of these wires into the slots of the twisting mechanisms.

Mounted on a shaft 48 aboveand preferably somewhat to the rear of the rear sprocket shaft 4 of the machine, and driven the latter by is a distributor head or roll 49. The ends of the shaft 48 are journalled in bearing brackets 51 carried by the side frame members3.:

' The" illustrated embodiment "of distribu discs. 52 secured to the shaft 48 -and provided with' series of alined circumferentially equally spaced grooves 53in which distributor bars 54 are received,*these' bars being bolted as at 56 or otherwise suitably secured tothe discs 52.

The outer. longitudinal portion of each distributor .bar 54 is formed in saw-tooth.

- fashion, the teeth 55 of the two bars on oppositesides thereof being staggered relative thereto. in ali ment. The bars are; spaced apart 1n 'accor ance with the spacing apart of the twisting mechanisms T as the latter ap preach andmove beyond the line of centers of the, rear sprocket shaft 4 and the' distributor head shaft 48, each bar being capable of passing freely down between successive ing upwardly out of the path of movement of the twistin mechanisms. rThe'parts are therefore so imensioned that the twisting mechanisms mesh with v the distributor headbars similar to the mannerof gears.

of the driving relationship .bE-Q

' By virtuev tween the rear sprocket shaft 4' and the d s tributor head shaft 48, it will be understoodthat the cooperating twisting mechanisms-i and the distributor head bars constantly move in the same direction toward the front of the machine. v a

The toothed portion of each bar has its opposite sides bevele 4 grooves 58 between adjacent teeth 55 are the side 57 toward th'eside 56, as indicated at 59 and 60 respectively. Because of the flaring of the walls of the grooves,it will be appreciated that each tooth is larger or wider on the side 57 than on'theside 56. Each tooth is therefore in effect a cam whose operation will appear more fully as the description proceeds.

The ad acent grooves 58 in each bar 54 are spaced apart a distance equal to-the distance between twisters 27 and are arranged to move in the planesjof movement of the twisters longitudinally of the machine. Thus the radial planes containingor passing through the centers of the cams on the various bars of the distributor head are arranged in spaced: relation to the various twisters 27 'in' the twisting mechanisms T.

The outer'most portion 59' of the bottom of each groove '58 is so located that when it is disposed substantially on the line of centers of the rear sprocket shaft 4 and distributor head shaft'48, it'is spaced from the bottoms of the succeeding twisting mecha- 65 nisms, in a direction substantially parallel tor'head or roll 49 comprises a plurality of The teeth of the alternate bars are I twisting mechanisms and subsequently pass-,

(1 at 56 and57, and the deepened and their side walls flared fromc to said line of centers, a'distance substan tiall equal to twice the diameter of the wire em oyed in making the fabric (see Fig. 1). If no wires are omitted, the portions 59' will still effectively deposit the mesh wires 26 in the twister slots. In the event the wires 25 and 26 are of different diameters, the distance referred to will be substantially equal to the sum of'the diameters of the wires. This will insure pro er positioning of the-meshwire 26 n t e correspondinglslots of the said succeedin twistingmec anism without kinking t e wire and will also provide adequate clearance for alternate line wires 25.

Slots 61 arrangedcentrally of and extending transversely through the cams or teeth 55 are provided to accommodate alternatelinewires 25, sothat said wires'may pass freely, without interference from the ms 54, from twisting mechanism to twisting mechanism as clearly seen in Figure 1. Thebottom offeach slot 61 is preferably spaced from the bottoms of the coo erating twisting" mechanism slots, in a irection substantially parallel. to the line'of centers of the rear sprocketshaft 4 and-1 the distributor head shaft 48," a distance substantiall equal to or greaterv than the-diameter of t e hne'wire 25,- in ,orderthat adequate clearance may' be'vprovided for said wire. The actual shifting of the various mesh wlres alternately into'stagg'ered twisters 27 .of the successive twisting mechanism will .beunderstood more fully upon reference to 1 the diagrammatic showin in Fig. 14, wherein certain of the twistmg mechanisms areviewed from above and the cooperating distributor bars up from'below, as a glance at Fig. 1 will serve to show. For the purpose'ofthe ensuing description, three successive .line wires are designated in Figure 14 respectively X, Y and Z, and the two mtermediate mesh'wires are designated respectively V and W, the mesh wires issu- 1 .mg as above pointed out from the openings 45 in the guide bar 46. In addition, the two distributor bars shown in'Fig. 14 are designated 54 and 54", respectively, and these same designations are applied in Fig. 1 to the same two adjacent'bars. It will be noted that the bar 54 in Fig. 1 has just moved into co operative relationwith the mesh wires, and this relationship is clearly shown in Fig. 14, certain of the ,mesh wires being designated V and W as explained above. At this point in the'operation of the machine, the mesh wires extend in substantially straight lines from the grooves 58 in the precedingdistributor bar 54' rearwardly to the uide bar 46. With the continued forwar movement of thedistributor bar 54, the latter proceeds in its descent, and since the mesh .wires are constrained by the guide bar 46 and the forward twisting mechanism opemngs' 23"1will of course-also be provided in roper relation to the slots and gears.

e rounding or'flaring portions 27" of the slots 28fserve to guide the wires 6 thereinto, even tho "the slots 28 may for some reason or other be'somewhat out/ of register withthe corresponding slots 24 inthe twister holding late's. i I n I am aware t at many changesflmay be made and numerous details of construction may be varied through a wide range without departin from the principles ofthls inventionan I therefore do not pur ose I the patent ranted hereon ot erwise than necessitate by the prior art.
