362,841. Tufting-machines. FAIRWEATHER, W., 65, Chancery Lane, London. - (Singer Manufacturing Co. ; Elizabeth, New Jersey, U.S.A.) Nov. 7, 1930, No. 28514/31. Divided on 362,615. [Class 112.] A guide 111, Fig. 10, is pivoted on the machine head 4 of a hook-needle tufting-machine to prevent the pile threads of a previously formed row passing under the needle foot. The guide is curved to recede gradually from the line of the loops and from the normal to the work support. The machine is similar to that described in Specification 362,615. Specification 362,616 is referred to. Needles, vibrating laterally; feed by needles; feed by devices engaging the upper surface of the work.- The needle-bar 9 is journalled for reciprocating in a vibrating frame 12 which also carries the feed-bar 26. The frame 12 is oscillated about a pivot 13 by a rock shaft which is operated from the main shaft by an eccentric. The work is fed by the needle and a foot 24 which engages the upper surface of the work and is carried by the reciprocating feed-bar 26. The feed foot, Fig. 9, is serrated on its lower surface and is slotted at 107 to clear the needle and at 108 to clear the thread. In front of the needle the feed foot is widened to provide a guide surface 110 for the loops. The presser foot 46 and feeding foot 24 are operated to engage the work alternately by a lever 53.
