Application filed January 10,1907. seen No. 851,678. f

To all whom it may concern:

Be it known that I, LOUIS N. D. WILLIAMS, a citizen Scott and myself as assignees of David .C. Bellis, theobject of my present invention being to produce a backing web which is better adapted for the production of a fleece than is the backing web of the patented fabric.

In the accompanying drawings-Figure 1 is an exaggerated View of a piece of my improved fabric looking at the face side of the same; Fig. 2 is a view illustrating the appearance of the-exposed face of the back web of Figs. 3 and 4 are views illustrating the The fabric forming the subject of the'aforesaid Letters Patent No. 709,734, comprised two webs, one overlying the other and united at intervals by a loop of the yarn of one web engaging the other web, and the fabric forming the subject of my present invention is of a similar character, thus in Fig. l of the drawing, 1 represents the face web and 2 theback web, the stitches of the face web being shaded in order to more clearly distinguish them from the stitches of the back web, which .are unshaded. The two webs are connected at intervals, as shown at 3, by loops of yarn of the face web engaging with wales of the back web, although any of the other modifications of the tying structure, such as illustrated a in said Bellis patent, may be used, if desired. The distinction between the fabric forming the subject of mypresent invention and that of the Bellispatent is that in my improved'fabric the stitches of both webs are drawn in the same direction, whereas in the Bellis fabric the stitches of the face web were drawn tothe front face and the stitches of the back web were drawn to the back face of the fabric; The exposed face of-the gigging the yarn of which the said back web was composed, but when the stitches of the back web are drawn towards the front face of the fabric, in accordance with ,my invention, the exposed face of said back web presents a surface composed wholly of loops, as shown in combined with the usual cams for reciprocating the same for knitting purposes, and with one or more yarn feeds for each set of needles, the yarn feed for the needles 4 being represented at 4 in Fig. 4, and the yarn feed for the needles 5 being represented at 5* in 3.- Although my invention is applicable either to straight or to circular machines I will, for convenience, refer to the needle carrier 4 as a cylinder and to the needle carrier 5 as a dia Owing to the fact that both the cylinder and dial needles draw their stitches in the same direction the web produced by thedial needlesoverlies that pro duced upon the cylinder needles and it is necessary to cylinder needles may rise to receive the yarn from the yarn guide 4*. For this reason the dial needles are projected clear of the dial 5 and to a point beyond the cylinder needles 4 wherever one of the yarn feeds 4" occurs,

- the needles are of the character of those in the machine 1906, by use of a special cam for effecting abnormal proje'ction of the needles or if the needles are of the ordinary type having butts for the-action of the knitting cams. They may, by the action of suitable jacks, such as those shown in Patent No. 577,789, dated Feb. 23, 1897, be projected, before they reach each feed 4 into aspecial dial on the inside of the needlecarrier 4 and returned by another set of jacks after they have passed the yarn feeding device.

In order to effect the tying of two webs together se-. lected dial needles may be only partially projected as shown by dotted lines in Fig. 4 instead of being fully projected as shown by full'lines in said figure, whereby .said partially projected dial needles will receive the loops of said yarnwhich will be cast off from said special needles with their stitches at the next dial yarn feed 5. v

' I claim:-

the other and united at intervals by yarn 0! one web engaging the other web, bo'th webs having their stitches facing in the same direction.

fabric, said mode consisting in knitting two webs by two sets of needles, both of which draw'stitches inthe same direction, and displacing the overlying web when the needles are being operated to knit the other web.
