UNITED STA T Es:

Applicationzfiled December 27, 1923, SeriarN Thisinvention. comprises certain improvements in or relating to machines for making wire netting, and-more particularly relates to machines of the type. involving superposed upper andlower pairs of longitudinal slides,

of semi-cylindrical segments intermediately d sposed at intervals with n seml-clrcular recesses in the contact faces of each pair of slides, each complementary pair of segmentsbeingadapted to be collectively re volved, by means of a sliding-rack'disposed within one of the longitudinal slides so as to gear. with a divided pinion, on the pair of segments, when the slides are in .certain relative positions, to therebytwist the pair of wires passing through the respective segments for formation of the netting, whilst intermittently the segments are adapted to I be'movedlongitudinally by the slides in known manner into new positions in which they again rotate in differently selected pairs, the arrangement being such that during the intermittent longitudinal movement of the segments by the slides, thesegments do not rotate.

The inventionh'as for itsipurpose the provision of means whereby, in case of the recesses of the longitudinal slides becoming worn out, the considerable expense of complete renewal of the slides may be avoided, and whereby the machine maybe adapted for the production of wire nettings of various meshes without the necessity for entire removal of the slides and replacement by slides having recesses of different size and pitch. 7 a

According to the present invention, the longitudinal slides embody interchangeable face plates in which are provided the semicircular recesses for the rotatable semi-cylindrical segments, said recesses being proportionate in pitch to the particular size of mesh to be produced, and being of a diameter adapted to accommodate the particular size of segment to be used. Advantageously the longitudinal slide is built up from separate metal bars, which may be of uniform or of diiferent qualities.

In order that this invention may be clearly understood and readily carried'into' practice, reference maybe had to the appended drawings, upon which:-

By this means the interchangeable face plates amay be fitted to existing longitudinal slides to replace plates having worn out recesses 0 therein, thereby avoiding the inconvenience and expense of complete renewal of the slides. In a similar manner the interoh'angeable'face plates a may be utilized to provide for different sizes of mesh, without the necessity for entire removal and replacement of the longitudinal slides. Thus a machine maybe adapted to produce, say, six different meshes of netting by the use of two extra sets of interchangeable plates a in conjunction with sets of segments d or by having two different ranges v of longitudinal movement of theslides and segments, meshes by changeable plates a and segments d.

part of the slide, and said body part may either be of solid form, or of a built-up conin Figures 1 to 3, the body part may comprise upper and lower web or flange bars 6 assembled in conjunction with a connecting base or intermediate bar f, the three bars having recessed joints 9 and being rigidly secured together by steel pins h riveted" therethrough, the bars being either of the same or of different qualities, for example,

thetwo web or flange bars 6 being of mild steel or cast iron, and the base or inter mediate bar being of cast steel to obtain greater rigidity;

z 1s the divided pinion on each pair of segments d, and j is the rackdisposed preferably within the rear slide for driving engagementwith the'series of pinions. 70 is the coil-holding tube supported by one of the lower pairs of segments (5, and from the interchangeable face plates a having the semi-circular recesses 0 are of rectangular cross-section, secured by bolts or studs 6 on opposite sides of a central web 7 "projecting inwardly from the body part c of the slide which may be of a plain channel formation.

What I claim as my invention, and desire to secure by Letters Patent is In a machine of the type referred to, for making wire netting, the combination of a facially opposed pair of slides arranged for a parallel reciprocating movement in opposite longitudinal directions, a pair of longitudinally extending bearing plates embodied detachably in the opposed faces of the respective slides, said plates having longitudinally spaced pluralities of semi-circular bearing recesses disposed inopposed pairs in the contact faces thereof, and sem icylindrical twisting segments disposed. in rotatable pairs within the respective pairs of recesses so as to take their bearings within said detachable plates; the spacing of the plurality of recesses in each plate being proportionate to the particular size of mesh to be produced, the recesses being of a diameter adapted to accommodate the particular size of segment to be used, and the plates being interchangeable in relation to the permanent'slid'es, to thereby provide for wear and avoid the expense of complete renewal of the slides, and to adapt the machine for the production of nettings of various meshes without the necessity for entire removal of the slides and replacement by slides having recesses of different size and pitch.

In witness whereof I have hereunto set i my hand.
