This invention relates to knitting machines and more especially to the web holding mechanism of such machines. v (01. 66--107) ' butts l8 of the web holder's l9 arranged in the grooves l5. ‘ A web holder ring 20 ?ts tightly into the upper end of the needle cylinder l0 and has an ex teriorly turned ?ange 20’ to rest upon the top ingly holding them in position for free recipro- ' edge of the needle cylinder. This ring 20 also has a substantial ?ange 2| extending outwardly In known web-holding mechanism, a web from an upper part thereof and providing a pair An object of this invention is new and novel means for lubricating the web holders and yield cation. ‘ . I of spaced parallel bearing surfaces 22 and 23. holder ring has radial slots in which are ar The bearing surface 22 is provided by the bottom 10 ranged the web holders for reciprocation by a . 1O rotated cam. Each web holder has a portion for surface of ?ange 2| and the surface 23 forms ‘engagement with the bottom of the web, holder ring to prevent vertical movement of the holders by the knitting needles. > ' Heretofore, it has been customary to lubricate the web holders and needles merely by pouring 15 oil on to the Web-holder ring which is very ob jectionable due to the fact that there is nothing to prevent the oil from running off with theresult v20 that the web holders and needles run dry and become hot, causing excessive wear and the formation of a black substance which, when the mechanism is again oiled, is wiped oif'on the fabric. The present invention obviates the con 25 ditions above described and, according to the invention, the web-holder ring is provided with an annular groove in which is arranged a felt wick which is engaged by the inner ends of the web holders. The felt wick is saturated with oil 30 and reciprocation of the holders causes applica tion of lubricant to the sides as well as the bot tom of the holders with transfer of some of the lubricant to the needles. The thorough lubrica tion of the holders and needles prevents them 00 Q1 from becoming hot and minimizes the wear. Other objects, novel features and advantages will become apparent from the'following speci? cation and accompanying drawing, wherein: Fig. 1 is a vertical section through a web 40 holding mechanism embodying the invention; Fig. 2 is a plan view of the web-holder ring; Fig. 3 is an enlarged ‘ fragmentary section _ through the web-holder ring showing a web holder in elevation, and 45 Fig. 4 is a fragmentary perspective view of the web holder ring. ' The needle cylinder I0 is provided with ex terior grooves II in which are arranged needles I2. A web holder bed I3 is tightly ?tted on a 5 O flange |4 formed on the needle cylinder l0. As is usual in the art, the bed I3 is radially grooved at |5, the last-named grooves being spaced be 55 tween the needle grooves “. On the bed In is rotatablymounted a- web-holder cam ring l6 having a ?ange H for engagement with the part of the top of the'ring 20. The body of the ?ange 2| has an upstanding portion 2|’ which is substantially triangular inv cross section, the _ hypotenuse of the triangle extending down wardly and inwardly, whereby a downwardly and inwardly inclined surface is provided. The part 2|’ is provided with a plurality of radial slots 24 to receive the web-holders and thebody por tion of ?ange 2| is provided with the slots 24" for the needles 25'. As is well understood, ring 20 supports a plu rality of web holders 25 for movement radially of said ring, and guides them during their move 20 ment in and out. These web holders are each provided with an upper arm 26 which passes through the slots 24 and rests upon the upper bearing surface 23, and a lower arm 21 which moves under the ?ange 2| with its upper surface engaging the under bearing surface 22. ‘This 30 arrangement of arms and bearing surfaces and slots insures proper movement of the web holders during operation. I provide an annular groove 28 in the upper surface of ring 20 and providea wick 29 of felt 35 or other suitable material in said groove. It is to be noted that the wick 29 is located near the inner ends of the radial slots 24 in the web hold ing ring 20 and near the bottom of the inclined surface 30 of the slotted portion of said ring. Any suitable lubricant is used to saturate the wick 29. The arm 26 of the web holder 25 en gages the wick 29 and as it reciprocates across the wick, it is lubricated. Some of the lubricant is carried by the web holders through the grooves iii 5 24 and supplied to the needles. Thus both the web holders and needles are thoroughly lubri cated thereby preventing them from becoming hot and minimizing wear. Also, the wick 29 serves to yieldingly hold the arm 26 in position tending to prevent canting of the web holder by pull exerted from the needles I2. The wick, therefore, not only serves to effect lubrication of the web holders and needles, but also minimizes 2 2,120,796 the possibility of binding of the arms 26 and 21 . against the surfaces of the ?ange 2|. The above-described arrangement provides 1 a highly e?lcient and inexpensive device- for ef fecting thorough and uniform lubrication of the web- holders and needles. The wick-retains suf.?cient lubricant for a long period of operation and reduces waste of lubricant to a minimum. ‘ ' ' - . having a slotted ?ange provided withvan'annu lar surface coplanar-with the bottoms of- said . slots, a. groove in said annular surface, a lubri eating wick in said groove and web holders in. said slots ‘engaging said wick. - - 6.‘ In a knitting mechanism,_ an‘ exterlorly grooved cylinder, needles in-the grooves, a ring carried by said cylinder and-‘having radial slots, » - It is one advantage of the arrangement that no: web holders in said slots, ‘each web holder be 10 additional mechanism is. required for the knit- ‘ ing arranged between two-needles,‘.and an annu 10 ting machine as it is necessary .only to provide -' m lubricating‘ wick supported by said ring for. . a groove in ‘the web ,holder'ringadjacent the inner ends of the-webholder grooves. simultaneous' engagement ‘by said web holders.
