Class 8

Adjustable Driven Feed-Rolls, for Mechanical Power.

MACHINES OF CLASS 8.

Bed four feet long, 28 inches from Needle to Base of Arm. Oscillating Shuttle Mechanism.

Corresponding in their general features to the machines in Class 5, previously described, the machines in Class 8 are designed for the same purpose, viz.: the strong stitching, in long lengths, of several plies of heavy fabric of any thickness not exceeding three-quarters of an inch.

The machines in this Class are capable of stitching to the centre of a belt 56 inches wide; they have a longer arm at an increased height from the bed, upon the face of which a clear space of twenty-eight inches is obtained from the needle to the base of the arm.

Machine No. 8-1 is provided with feed-rolls driven by ratchet, and has either a flat or a roller-presser, as desired. It has tight and loose pulleys, with conveniently arranged belt-shifter; its guides slide on a round rod.

Machine No. 8-2 is identical with No. 8-1, excepting in the fact that the guides are operated by a screw, thus obtaining an exact known movement of the guide for each revolution of the hand-wheel.

Machine No. 8-3 is of the twin-needle type for simultaneously making two parallel rows of stitching one inch apart, the machine being provided with two Cylinder-shuttles and a Needle-bar carrying two needles; otherwise it is the same as Machine No. 8-1.

Machine No. 8-4 also makes two parallel rows of stitching one inch apart; it has either Flat or Roller-presser, Screw Guide and tight and loose pulleys with belt shifter.

Machine No. 8-5 is single needle, and has drop-feed and vibrating presser. It is capable of a great variety of work, especially on thick, soft goods, such as Bed Comfortables, etc., for which it can be specially fitted with an auxiliary presser.

The Vibrating Presser, as constructed in regular course, has a lift of 14 inches from the bed. It moves forward at each stitch in conjunction with the feed, and is then automatically lifted and returned to its former position, thus preventing any pushing back of the upper portion of the material.

The Special Auxiliary Presser for soft or padded goods is attached to and works in conjunction with the needle-bar, pressing the soft material down seas to give free action to the vibrating presser, and fully protecting the needle from being caught or sprung out of place.
