t known that we, Josnrrr lVINKLsR, ianical engineer, and PAUL Rome, mexnical engineer, both citizens of Germany, 3 th residing at Ptornheim-Dillweissenstein, wernaany, have invented certain new and "nil Improvements in the Manufacture Annular Plait or Netting in the Form of 'iubes, of which the following is a specifi- Zlhe present invention relates to a machine for the manufacture of tubular link-mesh The object of the invention is a ne in which the wire rings or links c formed are immediately exposed view so that any defects in the work can 'ly observed. Furthermore the ma- 'ne so constructed that these detects e. g. )p ed meshes, can be easily made good. ier objectis to so arrange the feeding mechanism of the tubular fabric which is ted circuinfereni'ially and upward as the links and rows of links are the upward feed can easily be hand, as may be, for example, it the wire is not of absolutely thickness, which caus s the autoward Feed no longer to correspond the size of the links. The maalso easily adjustable to various ""of wire and sizes of links. .Adional improveu'ients will be apparent roin the following description.

For this object, the machine is provided with a vertically movable carrier for the tubular net to whichthe upper portion of tee tubular link-mesh fabric is attached. Tl ier has two motions: the one circircumferential and the other verti *1 or longitudinal following the completion of a row of links 1n order to raise the .50 1 can be regulated by Tier a carrier ring, to

which a line adjustment can be imparted vertically. and from which the net is suspended, so that by-shit'ting the carrier. ring compensation may. he obtained for inequalities in the wire, and'the machine easily adjusted various thicknesses of the wire. l urthermore the vertical feeding movement of the net carrier can easily be adjusted by means of a screw or similar device. The lower end of the tubular net is conducted between an inner guiding cylinder and an outer ring, and the tormationland connection of the individual links is effected below the lower edge of this ring, so -that the links, as they are termed, are plainly visible below this lower edge.

In the accompanying drawing, .Fig. 1 shows an elevation,;.F-ig. 2 the upper part of the same in section taken on line 2-201? Fig. 1, Fig.3 asec'tion taken on line-33 of Fig. 1, Fig. 4: aview of a dividing mechanism, Fig. 5 an underside plan of :Fig. 1; Fig. 6 is a partial horizontal section substantially on line 66.ot' Fig. 1, looking upward, and 7 is an enlarged elevation of a portiodol a link-mesh .tabric such as my invention is designed to produce.

l cylindrical block C mounted rigidly in the bed plate A. In the block C a tube 78 is rotatably mounted, incapable of vertical displacement. It carries at its upper end the spreading ringD and the guide column B, which is screwed into the'tube B by means of'ithe threaded stub 13 and presses the spreading ring D rigidly on to a shoulder B near the end of the tube.

(in the upper surface of the block 0' there rests the guideplate F for the tubular linkmesh fabric, said plate being provided with a projection or collar F extending .into a recess in the block (,3. This plate "is .conuected. by means of spin 7 with a feed rod 7' movable upwardly in the interior of the tube B when the lower end of said rod is engaged by the pin a carried by a feed lover a. f are two slots in the tube B which permit of the upward and downward motion of the pin f with relation tothe tube B 7 is a spring which bearsat its upper extremity against the spreading ring" D and presses f are two adjustable screw nuts the guide plate F downwards, as soon as the pin a is drawn back downwards.

The net-carrier consists of two feed rods EE, which are screwed into the guide plate F and pass through holes inthe spreading ring D, so that they rotate with the latter and with the guide column B.

The plate or ring G for holding the net N. is moved upward intermittently along the column B by means ofthe teed rods For this purpose two clamp couplings are provided which operate alternately. g are wedges which are arranged in thenet holding plate G, and against which two loose wedges g operate through the action of the rollers mounted. therein, the pressure of the weak springs bringing said wedges 9 into contact with the innersurfaces oi? the feed rods EE. On the upward movement of the feed rods EE the wedges g, will effect a clutch connection between them and the net retaining plate G, the later being carried upward with said rods. When the feed rods EE descend this clutch connection is loosened, so that these rods can descend alone. At the same time the plate G which holds the net is held firmly against column B by means of a second wedge connection, which prevents any motion downwards. This second device, shown best in Figs. 2 and 6 con sists of the wedges h on the plate G and the wedges 7L1, which come into contact with the column B under the pressure of the springs k rollers h being again arranged between the surfaces of the two wedges,

h is a ring loose on the column B and movable lengthwise thereon by hand for the purpose of releasing the two clutches in orderto enable the net holding plate 6 to be adjusted manually. If this ring fi is pressed downwards it will strike against the upper ends of the wedges g and in, thereby loosening the clutch. Instead of the wedge clutch there may be employed, of course any other approved form of friction clutch or connection.

The tubular net N is suspended from the" retaining plate G, (on which it is held by means ofa groove and a rubber rings.) above the spreading ring D. This ring D is rooved to correspond with the size of the links of the link-mesh fabric and is provided on its upper edge with a cone shaped chamtering or bevel d, and has a somewhat larger diameter than the ordinary suspended tubular net, so that it will somewhat open or spread such net and the link fabric suspended therefrom (see Fig. 1). When the link-mesh fabric is raised above the ring D, a row of links will thus lie on the chamfering or bevel d, which thus causes the links to be adjusted horizontally. Underneath the spreading ring D the tubular net N or the tubular link-mesh fabric again becomes narrower, so that at the under edge or the ring D the fabric again tends to contract and conforms to the grooved guide plate F. The latter is surrounded by a guide ring with an intervening space such as will allow the net just'to pass through comfortably. This ring ii is mounted loose on a ring support K, so that while held against vertical motion it can rotate freely and be carried round by means of the friction of the rotating net, or may be positively rotated by means of a feed mechanism which is not shown. This ring causes the individual links of the link-mesh fabric to fit exactly into the ribs of the guide plate F, so that every time the corresponding links of the last formed row of links can be brought correctly in front of the link shaping and connecting mechanisms in such manner as may be desired.

The rotation of the guide plate F with the column B and the rods EE is effected by means of a toothed wheel as. The pawl m engages with the latter, orcer, aftereach link has been formed, to cause the plate F to rotate further through a space equal to the distance between the links.

Since the links of adjacent rows are staggered, it will be obvious that on passing from one row of links to the next, the rotary feed must take place by an amount equal width of a tooth. During the "formation of one row of links, the feed pawl m is operative while the feed pawl m is held out of engagement with the ratchet wheelm by a pin on the slide m engaging behind the projection m on the pawl m At the completion of this row of links. the slide m moves forward (towards the left hand Fig. 5) and thus causes the feed pawl m to engage with the ratchet wheel or. same time, the feed pawl m is lifted oil the wheel on by a'pin m on the slide m This simultaneous movement oi the two slides is obtained by an oscillatory connecting lever m, which moves the two slides m m in opposite directions by means of the grooves m m and the pins m ,.m This mechanism is actuated by the ratchet wheel 71, provided with a series of pins a and on the completion of alternate rows of At the linlrs (for instance the odd-numbered rows) one of these pins n bears against the rlgld projection 92. on the slide and thereby moves the slide the necessary amount towards the ratchet wheel m. This wheel operated from the machine through any lso movable lengthwise of said axis, mechanism for turning sald holder about its 2.1 individual linlrs are formed, and means for moving the holder lengthwise of its axis the completion a circumferential row of links.
