This invention relates to machines for the production of chains, mail, ring mesh fab-v ric and the like. It concerns more particularly machines of the type in-which open;

wire ringsor links carriedon a plurality of supports are taken off simultaneouslyfrom the lower ends of the saidnsupport-s,inserted inthe links previously? formed and then i closed. a c

1G il'cccircling to the method of operation of this type of machine for tlIG'PFOdLICtlOH of mesh fabric, links are taken ofl simultaneously from a number of supports correspondingzto the number of rings in the full width of the fabric. Inthismanner a whole row of openlinks may be suspended simultaneously in the r-ow of links previously formed, (cf. German Patent No. 291,245), w

The present invention has as its object certain improvements in this ,method of opera tion and in the devices for carrying it into constitutes a transferable support,is adapted ac tobe readily 'removedfrom the device forming the open links and associated, carrying the said links, with-magazine supports in the mesh making-machine in such a manner that the latter supports maybe filled with open linksfrom the former while the machine is in operation. Since the link-forming device can turn outopen links much faster than the mesh making machine can operate, one .or-a few of the former devices is sufficient to sup-.

' ply all the links for a mesh making machine I of-thekind mentioned with ab out fifty "link supports. V ,A further material improvement accord- 7 ing :tothis inventionis the employment of pairs of needle-like tools for holding the downwardly suspended fabric in a manner similar to that in whichthe. said tools have i already beenused'in the production, accord.- ing to the step by stepmethod of manufac- =ture,;rofirings and ring-formations (cf.

space which: 15321 11 important drawback obviated in the mesh making machine according to {the present invention inwhich there are only the tools for feeding and closing the completed links.

An advantage of the mesh-making machine according tothe present invention resides in the possibility of readily adapting it for the production of fabric with patterns in dilierent colours. {It-is not only possible to :pro-

duce differently coloured longitudinal strips simply by filling the different supports of a single row with different coloured links, but

also to produce anydesired patterns in the following manner I *Two' or mo e rows of link supports are arranged one behind-theother and the feed deviceffor supplying the links from the lower ends'of the supports to the points where said 7 links 'are= incorporatedfinflthe' "mesh is aranged t o-Qpera fi h h ends of the rows ofsupports.

The invention may also be readily modi-' 1 fied for the production of a row of chains side by side. g

This modification is arrived-at if-each link removed from the supports is suspended in a single completed chain link and notkin two. as inthe a e o th rmationqf inglmesh 1O fabric? The result'is a'numberof chains-mar:

The lower end of the support 3 adjoins a transfer support 8 having precisely the same crosssection as the former. Said transfer support is mounted at thebottom in a bearing9 which is pressed upwardly by a spring 4 Th r w of fin sh dl k r a c lar Figs.

in -t'he plane perpendicular to the recess 12,

Operation of" he machine results in filling the transfer'support 8 withopen links which rest freelythereon so that they are able to slide downwardly under their own weight and bear one on theotheri Furthermore the movement ,o'f the forked sliding member 7 also has'a positive effect on the movement and the arrangementclosely one on the other of the links, After the transfer support 8 has been 'filled, its'connection with-the support o isbroken by lowering the former against 10 until it can be removed from the machine.

*It is clear that the machinemay easily be constructed to produce simultaneously sevme driving means,

For the sake of simplicity twenty-one such magazines only are shown, but they may number 50 or' 60 depending on the maximum width of mesh fabric or mail to be produced. The supportss are arranged with their upper ends S free so that they can be'supare provided 011 each support S. Said pro jections are so narrow at their neck parts 8 that the gap in the links K can readily slide past the same; the thicker portions 8 thereof I of the wire of the links.

are let into suitable grooves in the cross beams C, C and are secured in addition by means of screws 8 to ensure exact positioning vertically (Figs. 10 and 11). At their upper ends S the supports S are formed precisely as the lower ends of the supports 3 so thatthe transfer supports 8 may be readily centered thereon by hand and may be mounted se curely with respect to two perpendicular axes. The links K are transferred by their own weight, if necessary with some slight assistance by hand, into their correct position on the supports 5. Vibration by means of hammer blows may also be employed to ensure free fall.

The lower ends 8 of the supports S eX- tend so far through openings (Z in an upper guide plate D in the machine frame that their lower end surfaces are at a distance from a lower guide plate I) equal to the thickness The openings (Z correspond to the exterior shape of the open links K so that the latter can slide freely through them into guide passages D Suspenslon slides E moving in the space between the guide plates D, D are secured similarly to the teeth of a comb on a slide carrier E which is guided in the machine frame and is given its movement by eccentrics E I on the shaft B. r

The manner in which the mesh is suspended on the obliquely guided comb of needles F is clear from Fig. 15. In the position illustrated in that figure an open link K has a movement laterally throughhalf the width of a ring in order to present, in the correct position, the next open linksfed forward'by I the suspension slides to the row of rings suspended on said comb. The feed movement and the lateral movement of the combs F,

F are derived from cams.

Referring to Figs. 19 and 20 which illustrate a modification of the machine for the production of mesh fabric in several colours, two rows of supports S are provided and a locking device for thelinks is furnished at the lowerjend of each support. *In the arrange} memillusu-ated inFig.120cm end it of a doubleflever H -(lft hand" side) engages against theedgefof'thelower end surface" of the support?
