Class 19

THE machines in Class 19 have a cylindrical bed 16 1/2 inches in length, with a clear space of 10 1/2 inches from needle to base of arm; the cloth-plate extending outward from the needle varies in length according to the work for which the machine is specially fitted.

The diameter of the work-supporting arm is 2 1/4 inches, excepting in two varieties hereafter specified: there are eleven varieties in the class, but all have drop-feed arranged to feed lengthwise the arm and all have a balance-wheel located on the side of machine convenient to operator's right hand.

The feed mechanism on all the machines of Class 19 is arranged for reverse motion, so that the fabric can be fed either forward or back and a seam can be double stitched at any point. They can be operated by foot or mechanical power, the machine illustrated above (No. 19-12) being mounted on stand for foot-power and having its feed and presser arranged for leather stitching.

These machines are used for stitching elastic gores, back straps and back seams in shoes, for felling, closing or tacking seams in shirts, trousers and knit goods, and are adapted for all work of a similar character in which it is necessary that the thread shall pass from and to the inner surface of hollow forms that can be more conveniently stitched when feeding lengthwise the work-supporting

All the machines of Class 19 have the Oscillating Shuttle mechanism; the varieties numbered 4, 5, 11 and 12 have the long-beak shuttle, and those numbered S, 9, 10, 13 and 14 have a solid shuttle which oscillates about a large central bobbin, other distinguishing features being as follows:

Machine No. 19-13 is for cloth and is used for felling and closing shirtsleeves, overalls and similar work.

No. 19-14 is for leather and is used in Shoe manufacture for inserting back straps and for closing whole vamps.

No. 19-0 has an arm which is only 113 inch in diameter, thus enabling the stitching of cylindrical objects having a small opening.

The above illustration shows Machine No. 19-15 fitted with hinged lapseam feller (No. 588 (the manual from which this text was taken has the 588 marked out and 592 hand-written) A. and A.) for closing seams on heavy goods in the manufacture of Overalls, Jumpers, etc.

This attachment is commonly known to the trade as "the St. Louis feller;" it is only used on Singer sewing-machines and is of the highest efficiency for its purpose because of its convenience and its automatic adjustability to any variation in thickness of fold or seam.

All parts are yielding and so arranged as to secure the greatest facility for quick handling of work in making straight and perfect seams.

The illustration shows the convenient form of knee-lifter (No. 271 P. T. F.) used on power tables with this class of machines, also the Singer Under Driver (Screw Pressure), the most effective device for its purpose.

The above illustration shows Machine No. 19-16 fitted with felling attachment for closing shirts, etc.

Through the use of this attachment, which is peculiar to Singer sewing-machines, perfect seams can be quickly made by any operator using ordinary care.

The seam is more easily started than by any other method and the work is always in sight. The presser is located directly over the seam, which is carried evenly, without puckering or creasing on either side. Owing to its convenience for handling the work much time is gained by the use of this device, thus securing a distinct increase of product as well as improved quality of work.

Machines No. 19-8 and No. 19-10 make the zig-zag stitch for overseaming; they only differ in the diameter of the arm, which is 2 1/4 inches on Machine No 19-8 and 1 13/16 inches on Machine No. 19-10; the latter is shown in the above illustration as sewing up a seam on knit goods, for which purpose it is especially adapted and extensively used. The stitch made by these machines produces a flat and elastic seam, uniting two raw edges in a manner that is superior to any other. A special form of combined guide and presser is used (Parts No. 7111); the edge of a separator blade or guide drops into a slot in the throatplate, the raw edges of the fabric are carried against each side of this guide, which is sufficiently far from the feed to prevent its catching the edges. The guide is adjustable and is raised with the presser-foot so that the work can readily be removed.

Machine No. 19-10 is also used for closing the seams of leather cylinders, the edges of which are strongly and squarely united by the ornamental zig-zag stitch; it is used in the manufacture of round leather boxes or other stitching of a similar character. The diameter of the cylinder permits the closing of a small aperture.
