ABSTRACT:
The machine includes a stationary bridge frame having a sewing head mounted thereon, an upper carriage which carries the quilt, and a lower carriage. The lower carriage rides on track rails on the floor running in one direction, and the upper carriage rides on track rails on the lower carriage running in transverse direction. A drive unit is mounted on the upper carriage and has a drive wheel engaging the floor. The drive is produced by running the drive wheel, and rotating the drive unit about a vertical axis, to trace out a predesigned pattern. The drive wheel can be driven forward, stopped, and reversed. The drive wheel is driven a constant speed, and different kinds of elements of the pattern are produced by turning the drive unit a lesser or greater amount about its vertical axis. A computer unit is utilized, and instructions entered thereinto to turn the drive unit about is vertical axis at predetermined points. In that operation the drive wheel engages a flat surface board, without tracks, but it is also adaptable to use with tracks, alternatively, and in the latter case, the computer unit is de-energized. The construction and arrangement includes alternatively a complete quilting machine or an attachment that can be added in a pre-existing machine.
