'MAGHINEFOR MAKING WIRE-NETTING.

To all whom it may concern: I

Be itv known that I,.HAnaY A. DEUEL, a citizen of the United States, residing at Pueblo-,1 in the county of Pueblo and State of Colorado, have invented new, and useful Improvements in Machines for Making Wire Net-ting, of which the following is a specification. I

This. invention relates to machines for the manufacture of wire mesh netting, and especially to a wire fabric machine in which the wires of the fabric are united to form, preferably, a polygonal mesh, such as is usually termed diamond mesh netting.

The-main object of my present invention is to provide a machine which will weave the netting continuously, forming two rows of knots simultaneously across the fabric, the knots of the different rows being in staggered relation and being formed as the fabric is continuously advanced. I am thus enabled to greatly increase the output of the machine over those in which a single line of knots-is formed at one time or in which the wire is advanced intermittently. The forward line of knots is constructed ously revolving drum or rotary weaving head, which is provided with a plurality of sets of coilers, brought successively into op erative position. The rear row of knots is formed by a bank of twisters carried by a stationary head. and are. operated simultaneously with the coilers. The twisters are staggered with relation to the coilers, and

, are rovided with hollow guiding fingers whic are so positioned that the wires issuing from one finger of each pairof adjacent twisters pass into the same coiler in advance. y p 1 The rear of-the two lines of meshes will be formed by the grooved coiler heads or coilers which engage the-bends or angles of adjacent meshes and coil them over and under one another to form lock twists. The

completed fabric will be formed of alternate transverse lines of ordinary twists and locking coils or knots, each of which styles of knots or twists furthermore alternate between right-hand twists and left-hand twists, with the result that the meshes will be prevented from slipping 1en""'tudinal1y with the consequent narrowing o the fabric when subjected to longitudinal strain. Other objects of invention will be apparent from the f owing description.

while the scope thereof will be pointed out in the claims.

In the accompanying drawings; Figure 1 is a side elevation of a complete machine embodying myinvention; Fig. 2 is a top plan View of the same; Fig. 3 is a vertical section on the line IIIIII of Fig. 1; Fig. 4 is an enlarged detail of the rack and driving gear to intermittently actuate the coiler rack-bar; Figs. 5 and 6 are side and end views of one of'the twisters; Fig. 7 is a longitudinal view, partly in section, of the rotary weaving head; Figs. 8 and 9 are vertical sections through the stationary cross-"head carrying the twisters; Fig. 10 is an enlarged longitudinal section of the friction drive or clutch connected with the shaft of the take-upor winding drum; Fig. 11 is a vertical section of the rotary weaving head or drum on the line XIXI of Fig; 7 Figs. 12, 13, and 14, are enlarged detail views showing the construction of the diamond guides on the weaving head and the manner in which the coilers are carried thereby, Fig. 13 being a vertical section on the line XIIIXIII of Fig. 12; Fig- 15 is a to plan view of my machine with another orm of driving mechanism: Fig. 16 is a vertical cross-section on the line XVIXVI of Fig. 15; Fig. 17 is an end elevation of the machine shown in Fig. 15; Figs. 18 and '19 show a modified form of coiler and the knot made thereby, and Fig. 20 shows a section of one form of wire fabric adapted "to be made on my machine.

The machine herein illustrated is carried by longitudinal channel bars 1, 2, supported upon end. frame members 5, 6, which rest upon a bed plate 7. A winding drum 9, journaled in bearings carried by the standards 10, carried by the bed plate, receives the finished fabric and is driven by means of a chain 12 and sprocket 13 from the main drive-shaft, 15. In order that the takeeup or winding .drum may maintain the proper pull or tension upon the fabric, at 1 e same time allowing for the differential due to the increasing size of the roll, the sprocket :13 is loosely journaled upon the shaft of the drum and fri'ctionally engages a clutch surface 16, carried by a boss 17 on the shaft, as shown in Fig. 10. The proper frictional engagement between the sprocket and clutch surface is maintained by the spring 18 which is adjustably held by the can 20.

The forward row of knots or looking coils is formed b the coilers 21 carried by the rotary weaving head or drum 22, journaled in bearings 23. I have shown four rows of coilers, but the drum may be provided with any desired number of rows evenly distributed aboutits periphery, depending upon the dimensions of the mesh. The hearings and housings for the coilers are formed within the diamond guides 24, which are preferably cast integral with the drum. Circular recesses 25 are bored upon opposite sides of the diamond guides, I cutting through the inside wall of the drum as from opposite sides in order;that-- the shell of the drum may not be'weakened along the line of the holes. Each'of these bored recesses forms a' housing and the bearings for a coiler 21, which is provided with-bearing surfaces 28*, .and 2,8", and a central hub having spur teeth 29 which project through an opening 25, to engage a rack which re'c1procates within the drum. The hub is pro- 5 vided with a deep longitudinal slot 30, hav ing a flaring mouth normally in alinement with the passage between the pair of diamond guides orming the housing. The open end of the coiler recess is closed by a 30 bushing 32, which is shaped externally to conform to the adjoining surfaces of the diamond guides and the drum and is held in position b screw bolts 33. The upper portionof this bushing is in the form of a yoke, the arms 32 of which arch over the.

coiler and bear against the hub thereof, while the intervening sp'ace between the arms conforms to the slot 30.

In Fig. 14, the slot in the coiler is narrow, so. that the mesh wires will rest one above'the other. 'In Fig. 18, I have shown a wider slot divided by a central pin30', which separates the wires and forms a knot of the form shown in Fig. 19. A cylindrical rack- 35, is mounted to reciprocate with the rotary weaving drum, the teeth of which" engage the spur teeth of all of the coilers of the several sets, and the travel of the rack is suificient to cause the coilers to make I two complete rotations for each stroke thereof. The twisters which operate simultaneousl with the coilers to formthe rear row of o-ts or twists! of the mesh, are of the body twister type and, as shown in Figs.

5 and J6,comprise a tubular body 38, carrying spur gear teeth 40, and having a reduced rear bearingortionvv 39, with forwardly extendin tu ular guiding fingers 42. The bank 0 twisters is mounted n a 6. stationary two-part cross-head 45, shownin I cross-sectionin Figs. Sand 9, having trans verse sleeved apertures" 46 to recelve the body portion of the twisters, and a longi-' tudin'ally extendiiig slot or'bore48, which 55 .servesfas a guide-way for the reciprocation shown at 25, adjacent recesses being cut 15 operating through gears '60 and 61, to

rotategthe weaving drum 22, and through gear63 to rotate the shaft 65. The latter carries gears 67 upon either end, which engage gears 69 upon the transverse shafts 70, carrying mutilated gears. 72 and 73,

which operate to reciprocate the racks 35 and 50, respectively, and thereby, periodically actuate the coilers and twisters. The gears 73 mesh with teeth on the lower sides of the ends of the rack-bars 50, while the,

gears 7 2 engage separate auxiliary racks 76, which are bolted to bars .78, shown in detail in -Fig. 4, fastened in the ends-of the cylindrical racks 35, the auxiliaryrackshav- 1 ing a longitudinal bor'e79 which slides over the ide bar 80. 'The mutilated gearszare 1 so proportioned that they move the racks '35 and 50, alternately four times during each revolution of the weaving drum, that is,

once for each row of, coilers, and, as previously stated, the coilers and twisters make two revolutionsfor each stroke of the rackbars. 7

The 0 erationof the machine inweaving' the fabr1c; will be understood from the fore- I going description of the parts. The wire strands coming from the reels-or spools, pass through. the bores of the 'twisters and through the tubular guide. fingers across the weaving drum 22, thewires from adjacent fingers of ad'acenttwisters passingin pairs" between the iamond guides 24; and into the narr ow slots 30 of thenppermost row of coilers, one wire overthe other, and frotn thence pass over the guide roller 82"to'-.the I ,takempo winding drum 9. At the instant" the succ vertical position, the racks 35 andgfiby'are ing rows of coilers reach-the;

i; shifted by their mutilated gears, thus-teas;

ing each coiler and each twister to make two complete revolutions, the coilers and twisters- 3 being alternately rotated in opposite diI'BC -f sons. The pairs of wires being firmly baa 1 in the slots of the coilers will be coiled over and under one another twice to form a row of locking 0011s or knots, and simultaneously 1 one wire from each the adjacent pairs will be carried hOdilyii-bver and under one another twice by the twisters toform a twist or knot in the rear row of knots which are in staggered relation with the front row,

two rows of knots in thefabric being thus tied simultaneously. Each twister brings together a pair of wires from adjacent coil- ,ers and twists them toget er about'a 'ljnond guide, thus forming: e diamond rn of the fabricr As the next guides moves upwardly, the "rgm a; y

set of diainnn directlon, as soon as the coilers reach the" The, weaving "drum. ro

vertical position. tates continuously, and two rows of" knots are tied four times during each revolution'of the drum. 7

In Figs. 15, 16, and 17, I have shown the rack- bars 35 and 50, which actuate the pinions on the coilers *and'twisters, con nected directly to pistons 90 and 92, which reciprocate in cylinders 93 and 94, and are 7 actuated by fluid pressure,preferably compressed air. Compressed air from any suitable source enters the valve chamber 95, through -the inlet pipe 96, and passes through pipes-97 98, to the delivery chambers 97, 98", and from thence to the cylinders. The valve chamber 95 may be provided with a three-Way piston valve of the usual locomotive type, actuated by an eccentric 100, mounted upon the main driveshaft. The strokes of the valve must be so timed that pistons attached to the rack-bars will make four strokes for one revolution of the weaving drum, each stroke occurring as the coilers reach the vertical position. The pipes 97 and 98 serve alternately as supply and exhaust channels, the exhaust passing out at 1Q2. Suitable recording mechanism 104, may be connected to a worm 105 on the drive shaft.

It is obvious that various changes may be made in the construction and arrangement of parts of my machine, and I do not wish to be confined to the details therein shown, as'the broad object which I have in view is to manufacture a wire fabric on a weaving head which is rotated continuously when the machine parts are in operation, for interlocking, inter-connecting, or twisting together a series of wires which are suitably fed to said moving weaving head or drum,

and which are suitably connected or twisted during the movement of the drum without stopping or starting the same after once be ing set in motion, and to have two rowsof twists or knots formed simultaneously, the knots of one row being staggered with rela tion to those of the other row to form diamond meshes.

In the following claims, I do not wish to be understood as limiting myself to the details of construction of the individual elements which go to make up the several parts or combinations of the machine herein illustrated and described, as I regard the invention as of a character to admit of variations of these details within considerable limits without departing from its spirit and scope.
