Abstract: A needle plate member for a multiple needle loop pile tufting machine including double needle bars supporting transverse rows of front and rear needles in which at least one row of needles has a narrow gauge. Finger members or needle plate fingers project rearward from the needle plate and extend rearward beyond the rear needles. The transverse spacing between each pair of needle plate fingers is equal to twice the needle gauge of the needles having the narrow gauge. The wider gauge or transverse spacing of the needle plate fingers permits the fingers to extend rearwardly through both front and rear transverse rows of needles to adequately support the base fabric moving through the machine and penetrated by both sets of needles, as well as guiding the front loops past the rear needles to minimize tagging.

Abstract: A knock-down cabinet including a rear wall having forward projecting side flanges, a top wall having downward projecting side flanges, and a pair of opposed side walls having inboard projecting connector flanges for receiving the respective side flanges of the rear and top walls in an assembled position. The cabinet also includes a front door frame assembly having special shoulder bolt and slot connectors for assembly upon the front edge portions of the side walls, and one or more shelves received within the cabinet. The entire assembly of the cabinet is conducted with a minimum number of press-fitted plugs for assembly without tools within a minimum of time by unskilled labor.

Abstract: An electronic computer control for a hydraulic actuator for shifting a needle bar to different transverse positions in a tufting machine. The computer control directs the hydraulic actuator to be driven in response to the predetermined stitch pattern information in the computer control circuit, which determines the amount of relative tansverse shifting of the needle bar for each stitch location, in such a manner that the needle bar is shifted transversely only a needle gauge, or a multiple needle gauge, at a time and only while the needles are out of the backing fabric. The computer control also controls the velocity of the transverse movement of the needle bar in a gradual manner to minimize any shock created by the transverse movement of the needle bar upon the tufting machine.

Abstract: A stringed musical instrument having a sound box including a resonator having a solid top wall and a resonator chamber opening through the bottom surface of the sound box, and a bridge bar in contact with both the top wall of the resonator and the strings of the instrument.

Abstract: A multiple needle tufting machine incorporating a pair of relatively transversely adjustable front and rear needle bars, each needle bar supporting corresponding front and rear needles in transverse rows for simultaneous penetration of a base fabric moving in a feeding direction through the machine. A looper apparatus is provided incorporating transversely adjustable front and rear loop pile hook bars supporting a plurality of corresponding front and rear loop pile hooks pointing in the direction of fabric feed. Both the front and rear needle bars and the front and rear hook bars are relatively transversely adjustable between positions in which the front and rear needles are in alignment with the direction of fabric feed and a staggered position in which the front and rear needles are transversely offset. Separate yarns of preferably different characteristics are fed to the front needles and to the rear needles preferably by pattern control mechanisms to produce loop pile fabric of various patterns.
