Class 9
Adjustable Driven Feed-Rolls, for Mechanical Power.
MACHINE No. 9-1
FOR LARGE CANVAS BELTS, etc.
Bed, 18 feet long.
MACHINES OF CLASS 9.
The illustration on the preceding page represents the largest sewing machine ever constructed, especially designed for simultaneously making parallel rows of stitching on heavy Canvas or other Belting of unusual width, or for similar duty.
It will stitch any fabric, capable of needle puncture, from one eighth to one and one-half inches thick and of any width up to one hundred inches.
The bed is eighteen feet long and weighs over 5,000 pounds; it has power-driven feed-rolls and special guides adjustable for various widths material. The end of the frame, at the left hand, can be opened so that a wide and heavy belt can be not only stitched lengthwise, but the ends can also be lapped and stitched together before taking it from the machine.
This machine cannot be better described than by quoting the language of the award which it received, together with a medal, at the World's Columbian Exposition, as follows:
AWARD.
Machine No. 9-1: For Stitching two Parallel Rows on Canvas or Rubber
Belting:
POINTS OF EXCELLENCE.
1. Two needles and two oscillating shuttles for forming two parallel lock- stitch seams in heavy canvas and rubber belting up to 100 inches wide and one and one-half inches thick.
2. Powerful feed rolls sixteen feet long, capable of carrying material several tons' weight, having a bearing the entire width of the material, thus insuring uniformity and regularity in carrying forward the several thicknesses and giving elasticity to the stitching.
3. The mechanical arrangement for raising and lowering the upper feed roller by means of a horizontal shaft extending the entire length of the machine, connected with the hinged bearings of the roller by bevel gears at each end, and so operated as to be easily adjusted to any thick- ness of material.
4. Largest and strongest sewing-machine ever constructed, having a bed eighteen feet in length, with overhanging arm supported by and attached to both ends of the bed.
