KNITTING-MACHINLL Specification of Letters Patent.

Patented Nov. 3, 1914.

To alt w/wm ct may concern:

Be it-known that I LoUIs N. D. WIL- LIAMS, a citizen of the United States, residing in Ogontz, Pennsylvania, have invented certain Improvements in Knitting- Machines, of which the following is a specifi- ,of the latches of cation.

The objectof my invention is to prevent interference with the operation, or injury to the parts, of a knitting machine, due to contact of, the closing latches of the needles with other needles, web holders or other ele ments of the machine. This object I attain in the manner hereinafter set forth, reference being had to the accompanying drawing, in which Figure 1 is a View, partly in vertical sec tion and partly in elevation, of sullicicnt of the parts-of a rib knitting machine to illustrate my present invention, and Fig. 2 is a face .view of the same.

In the operation of an ordinary rib knit ting machine the latches of each set oi'zneedles are closed by contact with the stitches upon said needles, and, during the closing the needles of one set, the needles of the other set are projected be; tween the same, consequently, in the machines of the line gages which are now in use. there is liability of the latches of one set of needles'to contact with the needles oil xthe other set, or with web holders or other 'it'abric. In order to. overcome these stitches upon said elements of the machine, because of the side due to looseness of lit in the slots of the needles, or because of tho the needles in their grooves, the result being the injury or breakage of the latches or other elcnu-uts of; the machine, and consequentinterference with the proper operation of the machine. The same obyections apply, insome measure,

"tolkiiitting machines having but a, single nee le bed and intended .iiorlproducing iluin o 3E6" .tions Iprovide' for the-qlclosin'gof the latches of the needles before-they reacl'r the needles and consequently before they are in position"tocontaci: with web liol l i's or' chine, and, in they can other set.

By n-cierence, I combine the latch closer with the yarn guide of the macl1inc,jthe

a rib (hitting machine, before li e "elements-e1" the ma;

contact with the needles of thelatch closer thus located readily pcrliornr mg its intended function. In a rib knitting machine the latch closer preferably cooperates with those noodles which constitute the primary needles whether the some he of the cylinder or dial, thcsc primary needles of the machine shown in the drawing! being those of the cylinder.

The yarn guide 1 may be mounted and may feed the yarn a' to the needles in the usual way, but the rear portion of the yarn guide is cut away as shown at 2, so as to form a. slot, and preferably no opcnannlcd slot, in the guide, that member of the guide which is at the bottom of the HM having; combined therewith a latch closing linger 3, which may be either a ta wrcd and inwardly deflected. portion of said lower member of the guide or may be :1 separate piece secured thereto in any dcsircd manner.

The latch closing linger is so located that as the guide mores :lorward past the projcctcd needles said linger will pass behind the lower ends of the depending. latches and, as the needles are retracted, will tugage said latches and close the same, as shown in Fig. oi the drawing, the hitch being completely chisrnl, or the closing operation being" so for completed, before the butt end of the latch roaches the level of the projecting interposed noodles that there is no possibility olf contact ol the closing; latch with said interposed medics or with other and similarly localcd elements of the machine. lfluriug their old-di unn'cmcnt, the latches swing ihrou; h tho opmiingr 2 in the yarn guide, conscoiwutly the latter oll'crs no obstacle to said closing nmvcuuwul. ll not cssciiliul to oy-invcuti n, houcrcr, that the latch closer should be carried in or "on titutca part of tho yarn guid although such a construction i;-,' .ucl'crrml zis lhc most couvcuicut.
