IPI L ANDREW WILLIAM S'IOREY, OF MANCHESTER, ENGLAND.

MACHINE FOR WEAVING WIRE-NETTING.

To all 'whom it may concern:

Be it known that I, ANDREW WILLIAM STOREY, a subject of the King oit' Great Britain, residing at 45 Gaylor street, in the city of ltlanchester, England, have invented new and useful Improvements in Machines for vWeaving lWire-Netting, of which the following is a specification.

My invention relates to improvements in machines for weaving wire netting, and particularly to machines for weaving netting with a heXagon or diamond mesh.

My improvements consist of alterations in the construction and working of such inachines which will enable variations to be made in the pattern of the netting and the form of its meshes.

In carrying my improvements into eect I employ the usual or any known and suitable arrangement of weaving pinions mounted in halves in two sets of oppositely reciprocating slides or traverse bars and with reciprocating racks or equivalent means for rotating the pinions. In such arrangement each half pinion is threaded with wire throughout the entire series of pinions employed in forming the width of the fabric, and the traverse bars at each reciprocation move the two sets of wires and half pinions, one step, that is to say each wire and halt' pinion is moved opposite to the wire and half pinion next or nearest to it, before the nextrotation takes place. This obviously requires one additional wire and single halt pinion, over and above the number of pairs of wired half pinions employed, in order that the wires may intertwist when the pinions are rotated in pairs by the racks after the reciprocation of the traverse bars has taken place. I now arrange to have two or more additional single threaded or wired half pinions over an'd above the number of pairs of wired half pinions according to the number of wires to be crossed over at each step without intertwisting, and I also arrange that the traverse bars move the two sets of half pinions two or more steps so that each halt pinion passes over an intermediate wired half pinion or pinions before it intertwists. I also prefer to cause a dwell of the traverse bars at any desired meeting or crossing place of the pinions, and to give a halt` turn to the pinions during such dwell in order to cause the wires to interlace and further to interlock the selvage wires. The necessary Specification of Letters Patent.

change must obviously be made in the cams or equivalents which actuate the racks and traverse bars. The eiiect of these changes is to produce a wire netting of entirely novel design which may be varied according t0 the number of wired pinions passed over without intertwisting of the wires.

In the accompanying sheets of drawings, Figure l is a front elevation and Fig. 2 a plan view on the line AA, Fig. l, of my improved machine for weaving wire netting. Fig. 3 illustrates the improved wire netting when two intermediate wired pinions are passed over with interlacing movements. Fig. 4 illustrates the improved wire netting when three intermediate wired pinions are crossed over with interlacing movements but without intertwistinO. Fig. 5 illustrates a suitable form of cam for actuating the traverse bars when weaving the wire nett-ing shown in Fig. l, without interlacing. Fig. 6 shows the improved wire netting produced when one intermediate wire is passed over without rotation and consequent intertwisting of the wires, but with interlacing movements and interlocking at both selvages, and Fig. 7 is a view of a suitable form of cam for actuating the traverse bars when weaving the netting shown in Fig. 6.

In the drawings, a designates one series and a the other series of the ordinary twist ing pinions which are made in two parts as usual; b' the two traverse bars in which the two sets of half pinions are iitted and which are actuated by cams or equivalents in the usual way; c the tubes which contain one of the supplies of wire; 0l the wire shown in one tube only; CZ the other wire supply; f the racks which gear into and rotate the half pinions in the usual way; g a specimen of the wire netting which can be produced in my improved machine.

In the ordinary loom for weaving diamond or heXagon mesh wire netting there is, as already stated, always one eXtra wire and hall:l pinion over and above the pairs of wired halt pinions in one of the traverse bars I) to allow the wires to be intertwisted when the movement of the traverse bars has been effected; but for the purposes ot my invention it is necessary to have two or moreadditional wired half pinions over and above the number of pairs of wired half pinions, according to the number of wires and pinions to be passed or crossed over without inpinion in the traverse bar Z) farthest from the racks f and the other in the traverse bar next the racks, which means that only one intermediate pinion and wire is to be crossed over before the intertwisting takes place, in order to produce the novel design of wire netting g' as shown in Fig. 1.

Although .only one intermediate wired pinion is passed over in this design without intertwisting, I prefer to arrange the cams or equivalents, which actuate the traverse bars in such a manner as to .cause a dwell at every crossing or meeting place, while ,each pair of wired half pinions receives a half rotation by the racks f so as to cause the crossing wires to interlace, but without inter-twisting. The effect o f this nterlacing of the wires .at each crossing is to interlock the selvage wires at both edges of the netting and thus impart greater rigidity to the netting and a neater finish at each selvage.

It will also be readily understood that by crossing two or more intermediate wired half pinions, the design of the wire netting produced is correspondingly modified.

Although I arrange the extra wired half pinions., one in one traverse bar and the other in the other traverse bar as shown in Fig. 2, when a netting is required with fthe wires interlocled at both selvages as described and as shown in Fig. 1, it will be readily understood that when such finished selvages are not essential I may place both extra wired half pinions on either side of v.the ordinary wired pairs of pinions, and in the traverse bar farthest from the racks, and obtain a netting in all respects the same throughout its entire width except at the two selvages. Such a fabric would beuseful for reinforcing glass and for other purposes where a netting having the finished selvages shown in Fig. l was not essential. l When two vor more intermediate wired half pinions are crossed' over I also prefer to larrangethe cams or equivalents which actuate the traverse bars in such a manner as to cause a dwell, while the half pinions receivev a half rotation by the rack so as to cause thecrossing wires to interlace at every desired crossing or .meeting place, the necessary change being made in the vcam or equivalent so as to give the required length of slide according to the mesh and the number of intermediate wired half pinions to be VReferring to Fig. 5, Z2 designates the traverse bars containing the two series of half pinions a and a, respectively; z, the cam shaft'upon which is fixed the cam z'; 7'

a pair of links pivoted at j to the traverse bars b and at jz to the pair of rocking arms c which rock upon a fixed center m; n 12, a pair of anti-friction rollers carried at the extremities of the rocking arms and arranged to run upon the surfaces z" 2 respectively of the rotating cam z' which turns in the direction indicated by the arrow.

Thile the roller n is running on the surface z", intertwisting takes place until the roller a reaches the curved surface 3 which raises it on to the surface 2, thereby reversing the position of the traverse bars b and moving the half pinions one stage, passing over an intermediate pinion without interlacing, intertwisting then taking place so long as the roller n is running on the surface 2. When the surface i* reaches the anti-friction roller a, it reverses the position of the traverse bars and when the roller reaches the surface intertwisting is oontinued until the next change, as already described.

In Figs. 6 and 7, denotes the traverse bars containing the two series of half pinions, numbered l to 8 and lettered A to I, respectively. The links y' are in this case .Connected to a single rocking arm le on a fixed center m and with a single antifriction roller n which runs in a grooved cam o fixed on the rotating cam shaft z, in the direction indicated by the arrow.

In the position shown, the roller n is entering a curved portion o of the grooved cam, whereby the position of the traverse bars Z) is changed, then when the roller a liesl in the portion 02 of the groove, interlacing is effected by the movement of the ordinary rotating cams which actuate the racks and so give the pinions a half turn. IV hen the roller a reaches the position 03 in the groove the reverse movement is imparted to the reciprocating traverse bars and while it travels along the plain portion of the groove o4 the racks actuate the pinions and effect intertwisting of the wires.

Throughout my specification I have described imparting a half turn to the pinions when it is desired to simply interlace the wires without intertwisting them, but I wish it to be understood that under certain conditions it will be possible to impart a full turn without causing intcrtwisting of the wires, and I therefore desire to reserve the right of making either such full turn if required or a half turn as may be more convenient to cause the desired in* tirlacing of the wires without intertwisting t iem.

I am aware that it has previously been proposed in changing say for example from weaving wire netting with one-inch meshes to a weave with two-inch meshes to omit to thread wires through the alternate half pinions; but in such a case the wires are omitted from the half pinions which have to be crossed, whereas in my method all half pinions are threaded withwires without eX-cep-` tion from any desired pinion at or near one selvage to any desired pinion at or near the other selvage throughout the full width of the wire netting, and further the wires are preferably all interlaced where they cross. I am also aware that it has been proposed to produce a continuous web of wire work wherein all the meshes produced are of the same size but the wires forming the said meshes are crossed in part of the Width in such a manner as to cause the web to present smaller openings at this part than at the other part. In such proposed construction no alteration was to be made in existing machines, but a wire was to be threaded through every half pinion at that part of the machine where the small openings in the mesh were to be produced, and through every alternate half pinion on each pinion plate, where the large openings were to be formed. The pinion plates were to be moved through twice the distance between each pair of pinions and it was proposed to finish the edges in the ordinary way.

In the foregoing construction the object was to produce a mixed mesh wire netting suitable for poultry houses and the like inclosures, the smaller openings being placed next the ground to prevent smaller birds or animals from passing through; whereas in my method of weaving there is no mixed mesh, but there is one uniform weave of wire across the full width of the netting. Also in my method of weaving, as already stated, all half pinions are threaded with wires without exception from any desired pinion at or near one selvage to any desired pinion at or near the other selvage throughout the full width of the wire netting, and further the wires are preferably all interlaced where they cross. Again by increasing and varying the number of intertwisting coils I produce a novel ornamental efi'ect as illustrated in the examples shown on the drawing, my improved wire netting being particularly applicable for reinforcing plate and other glass, as well as for fencing and various other useful purposes.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed I declare that what I claim is l. In a machine for weaving wire netting, in combination, a pair of oppositely reciprocating sliding traverse bars, a plurality of pairs of wired half pinions mounted in said bars, a plurality of additional wired half pinions mounted in said bars, means for moving said bars to carry the half pinions associated with one of said bars over a plurality of half pinions associated with the otherof said bars, and a sliding rack operatively associated with said pinions to rotate the same to interlace or intertwist the wires.
