MACHINERY FOIR/VVELAVING METAL FABRIC.

To 62N- whom, it may concern.'

Be it known that. I, JAMES D. SMITH, a citizen of the United States, residing at Chicago, in'the countyof Cook and State` of Illinois, have invented new and useful Improvements in Machinery for `l/Veaving Metal Fabric, of which the following is aspecification. r

This invention relates to machinery for weaving metal fabric, particularly' metal fabric of thatA class comprising diagonal form quadcommonly known as dia- Metal fabric of this kind is made of wires or rods of largeor small diameter, and considerable diiiiculty is experienced in weaving theheavier grades rangular meshes,

of'fabric of this kind.

The object. of this invention isto provide a simple metal fabric weaving machine` whereby diamond mesh fabric 'of'continuous length may be woven from. short length wires or rods thus affording a great saving of time and labor.

To such ends4 this invention consists in a weaving mechanism obliquely disposed with respect to a line running longitudinally of the completed fabric, said mechanism being provided with slidable heddles for' guiding-certain of the wires or rods to the fabric .l inoblique lines, whereby .angularly disposed wires or rods of shortlength, may be interlaced t'o forni a'fabric of continuous length.

4The invention further consists in the novel features of construction, arrangement and combination of part-s hereinafter set forth and particularly defined in the claims i The invention is clearly illustrated in the drawings furnished herewith, of Which- Figure 1 is ay plan of a machine embodying my invention, with the supporting arms of the harness and hatten shown in horizontal sectiongfa section of the fabric, part of which is in the course of construction appears in the view, Figa 2 is a plan .of a fragment of the fabric made by the machine, Fig. 3 is side elevation of a fragment of ,one of the Vwires or rods. of the fabric, Fig. 4 is a side elevation of the machine looking in the direction of thearrow 4, in Fig. 1, Fig. -5 is a perspective view of a fragmentof a carrying bar of the harness, Fig. Gis a perspective view of a Vgroup of connected the width of the fabric.

In constructing t diamond mesh metal fabric of anyY given width. by hand, the wires or rods are first kinked and cut to lengths. The length of a wire or rod and its angular position. in the fabric, determine A number of wires are arranged parallel with each other and oblique-with respect to the length of the fabric, and other. wires arranged crosswise of the rst'set midway between their ends, and interlaced therewitl. Other wires are added and interlaced to complete the fabric.

In using this machine, double lengthwires' or wires whose length is any multiple of 'a single length wire` are employed in the construction of the fabric, one partof each -wire being placed in a diagonal line vin the fabric, and the other .parts of the wires being. cut ofi' during fabrication to provide wires for Y the other diagonal direction. For convenience I'will term the long wires or rods 'Y double length wires and the short or severed port-ions single length wires.

Referring to said drawings which illustrate a simple form of the invention. a. table or platform is represented at 13, said tableVv being mounted upon legs 14. and having its 95 end adjacent to the weaving mechanism of the machine, obliquely disposed. as seen at 15 (Fig. `1). The angle of the oblidue table end 15, is fixed as thatangle assumed by one set of the diagonal wires of the completed fabric, and the batten and harnessare arranged approximately parallel with said oblique end 15, as seen inFig. 1, On the ob- Y lique end-means are provided for holding the fabric position during the course of'f105 construction, oneform' of means comprising upwardly projecting pins 33. v Itis obvious that in place of providing lthe table itself may extend obliquely` with'frspet t0 then@ length of the fabric, deposited upon the table from the weaving mechanism, and. in that case the latter should extend approxi.- mately parallel with said holding means.

Beside the oblique holding means is the harness lil, for guiding the double length wires or rods, said harness acting to for'm a shed 7 through which the single length `lwires. are vinserted ybetweenv the double length wires. Said liarness-isshown :is having two sets of heddles 1G, 17, that are slidably mounted 'inA carrier .bars 1S, supported in any desirable manner, as for instance by arms 19, connected to the ends of oscillatory cross bars 20, tulcrumcd intermediate'their ends on suitably supported brackets 2l. In the formshown, the carrier bars of the heddles are arranged abovethe work and the arms extend upward therefrom to the bars 20, the brackets 2l, being supported from above, as for instance by bolting theinto a support above the bars 2C'. For convenience the lower ends of the 'arms may be guided by loops 22, sliding upon said arms and arranged toinaintain the two scctions of the harness in spaced relation to each other.

The heddles-of each section of thehar- -ness are. arranged to travel from one end of the carrier bar 18, to the other end in the operation of the machine, and for convenience the heddles are arranged in groups' v.connected together as byV a connecting bar 23, secured to their upperends (seen in Fig. 6). Each group of heddles is guided. to move along its carrier bar and as shown a `"convenient means for accomplishing this result comprises a horizontal 9 roove23EL in the carrier bar adapted to receive one flange of the heddle connecting bar 23.A The particular construction of said carrier bar isv immaterial to the invention, broadly speaking, and I have shown lit built up of'anglc irons (see Fig. 7) to formI the l. shaped groove for guiding theheddles iii their movement from one end of the carrier bar to the other. Each heddle .has an eye 24, at its lower end for receiving and guiding the double length wires. For' convenience,

an opening 25, is provided in the lieddle,y

intowhich may be hooked the end of a link 26, which extends upward from a trcadle 27. ln the form of machine illustrated there are four treadles, and the links are hooked into the openings 25, of the heddles at the end of the harness. Normally both sections of the harness would lie opposite each other, that is, in the same horizontal plane, but for the purpose of illustration, one section is shown as depressed and the other .raised to separate the wires to form the shed, it being understood that depression of lone of the treadles will draw down one sectionr ,ofthe harness swinging the bars 20, upon `their fulcrums, and raising the other section- `mesh and width of the harness. its is customary, the heddlcs of one section are offset or staggered with respect to theheddles of the other section, so that the alternate wires will be raised and lowered. in unison, in opposition to the intermediate wires.

The hatten l?, is located between the harness and oblique securing means," and is shown as carried by arms 28, extending down from levers 27, said levers being fulcrumed between their ends on brackets 29,

supported in any suitable manner, A cross bar 30,.cf,ninects the lower ends ofthe arnis 2S, and projecting' down from said bai 30,

are pin or prongs 3l, that ext-end down betweeii the double length wires vand enwith the single length wire to force it into place. A'hundle, preferably ,inthe forni of a bail B2, is employed for swinging ine hatten, said bail being loosely connected to the cross bar 30, as 'shown in Fig'. 11,

whereby it may have a limited amount of vertical. movement, and be capable of falling in front of the positioning" pins f th at project up from the end of the table 13. By swinging the hatten toward the harness (see full lines Fig. Ll) and dropping the handle in front of the pins the hatten is held in position, ready for the insertion of the single length wire. The b atten may be vided for lwithdrawingA the hatten V'from the 'work and as shown a simple form of means comprises a wire or other coiii'iect'ing device 34, extending each 'lever 2 7, andj having an eye, ar-

ranged to be hooked upona hook 36, secured` in the floor. By drawing down .both con;- nectinfa` devices, 34,- and hooking the eyes uponlthe hooks 36,1 the levers 27, are swung upon their fulcrums, the arms. 28 1aised and the battenlifted clear of the work.

The prongs' are shown as stationarily se-' but it is ob- -cured in the supporting bar, vious that they may beadjustable or movable as are the heddles 16, and likewise arranged in connected groups.

Beyond the harness are placed one or more supports 37 for-receiving and carrying the ends of the double length wires during the process of 'forming `the metal fabric. Any desirable form of support may of course be employed for this purpose.

.ln constructing metall fabric with this machine, kinke'd wires areused, each wire being twice tlielength of wire,required in a fabric of any given-width, or wires any desired multiple of that length are used, and the proper number (depending upon 4the ofthe fabric) threaded through the eyes of the hcddles, bring-ing one end of each wire to a line on the table coinciding with the far edge (as viewed in Fig. l) of the fabric to be constructed. The

down from the free end of.

.drawn forward. first disengaging the handle -from the pins lt/leans 'are proioo `taires',embraced inthe groups lettered A, B, :Cz comprise lthe ,number of double length .wires required to `tineke-.one diagonal secthe required number of single length Wires .oblique end 'its of single length l'Wires D, is then `and correspond tothe numbers in the group .JA y01' C.

The number of Wires in the groups A, 0,1), may be increased ordiminished, depending upon the space between the of the table and the hatten, caire being taken to not completely build up said space before advancing the finished fabric for making 'the next succeeding section. Either before or after the double length Wires have been placed, t-hose embraced in the groups A, B, are interlaced With short length Wires in that portion of their length lying on the table, this being done by hand in the usual Way, merely for the purpose of starting the fabric. This may le done by cutting oft the longest piece of wire lying on the'table, and interlacing it with the others, then cutting off the next longest one and interlacing it with the others and so on until a square, finished end is completed. Ob-- viously this is not necessary tothe @peration of the machine, but for the purpose or economy, the fabric may be thus started asx none of the material is Wasted.. A group for starting the manufacture of the fabric by the machine. The hatten isthen swung back' into the position shown in full lines in Fig. at, and the treadles of one harness section depressed vby the attendantsthere beingitivoin .the operation of the machine of the form shown. Depression of said treadle causes apde'pression of the harness section directly connected therewith, and a corresponding raising of the other harness secvtfiointhus forming a shed between the alternate and intermediateivires. Une attendant then inserts a single length Wire (indicated by dotted lines c) through the shed in front of the hatten prongs, after which the attendants raise the handle and draw the Wire between the alternate and intermediate double length Wires until it reaches the .proper position relative to the .next adjaceiit-,previously inserted single length Wire., The remaining Wires of the group D, are

inserted and .crowded to place, each-succeeding Wire of the group being inserted far enough to reach that. double length Wire next to the oneivhere the endofthe previoiisly inserted short 'length Wire stopped,

have been inserted and so that When` all of said -short length Wires crowded to place, their ends Will lie in lines coincident with the edges of .the completed fabric, as shown b v-vthe group of Wires indicated in dotted lines at D, lt is of Course underStOOd that prepared ,the .harness is yoperated to raise one series of the double length Wires and lowerf the other series for rone si iig-le length Wire and there- Vafter to lower the first series and raise the other series for the secnd single length Wire and so on to effect the interlacing with the single length Wires. The attendant on the near side of the machine then cuts olf the Wires of the finished fabric, draws them out ofvtliceyes -of the heddles which guided them, after which they are used to build up another diagoiial section of the fabric, The attendant unhooks the links 26, from the heddles and removes the two groups of lieddles at t-he end of the harness Where the groups of Wires A, extended, said groups sequentily other vside of the machine. The batteri .is then raised .out of the Work by pulling down group A, at the edge of theA of h'eddles being subg inserted in the carrier bars lat thev theconnecting devices 34, and securing it in group A, and the far Wires moving away.

double length Wires ioo from their original posit-ion, leaving a space' formerly occupied -by the group C. The

attendant on the opposite side of the niachine heddles into the carrier bars so as to occupy the space left by the advancement ofthe heddles therein, and tlien'inserts a group of wires C) through the eyes of said groups of heddles, bringing the ends of the Wires into alinernent with the far edge of t-he finished fabric. The former operation ofinsorting the single 'length Wires is then' repeated.

y F rom the above it is obvious thatl metal fabric having interlaced'diagonal strands may be made economically in continuous length from short Wires. or rods. to usedouble length Wireor rods for the sake of economy, as the severed portions of novvinserts the previously removed I prefer the Wires or rods areconveniently used in operated on by the machine ;t desire .tube
