Class 17.

THE machines of Class 17 have balance wheel at right of operator; the oscillating shuttle mechanism is inclosed at the extreme outer end of a cylindrical bed 21 inches in diameter and 16 1/2 inches in length, the clear space from needle to base of arm being 10 1/2 inches.They may be used either as flat-bed or as cylinder-bed machines, being fitted with an adjustable cloth-plate for such classes of work as make its use desirable.

These machines are adapted for sewing either leather or textiles and for operation by either foot or mechanical power.

There are sixteen varieties in this class, described as follows:

Machine No. 71-1 has drop-feed across arm at left of needle and is used in Shoe manufacture for stitching the quarter over the vamp; in other leather work it is used in the manufacture of Pocketbooks, Portfolios, Hand-bags, etc.

Machine No. 17-2 has drop-feed across arm at right of needle and is used for closing the seams of Shot or other bags after they are filled, sewing buckram on Jean Pants, Pocketbook manufacture, etc.

Machine No. 17-3 is for leather only and has wheel-feed at right of needle and a roller-presser; it is used in Shoe manufacture for stitching the vamp over the quarter.

Machine No. 17-4, illustrated above, for stitching in the ends of Cylindrical Leather Boxes, for Collars, Cuffs, etc., has wheel-feed at right of needle and is provided with an adjustable work-holding attachment.

Machine No. 17-6 has drop-feed up the arm for the convenient stitching of long tubular or cylindrical articles such as Shirt Sleeves, etc. Machine No. 17-10 is precisely similar to No. 17-6 excepting that the feed is reversible, which enables tying the end or any other part of the seam. Machine No. 11-1, drop-feed across the arm, has 2 needles and 2 shuttles for making two exactly parallel rows of stitching at one operation; the gauge or distance between the rows is made as ordered and may be from 1/16 to 3/4 of an inch, as desired. This machine is used in Shirt manufacture, for sewing strips on Ladies' Shirt Waists and for similar two row stitching where the use of a right hand cylinder-bed is desirable.

Machine No. 17-8, drop-feed across arm, and Machine No. 17-9, wheel. feed across arm, are provided with the Alternating Presser. This device comprises two pressers, acting separately and alternately; the first moves forward with the feed, is then lifted and returned to its position; the other holds the material down while the first rises and until it descends upon the fabric, but is raised while the material is carried by the feed. Each presser, while resting upon the work, forms a fulcrum upon which the other is raised, consequently the height of their movement always corresponds to the thickness of the material, thus allowing the free passage of material which varies in thickness, without affecting the integrity of the stitch.

By the use of this device, two or more pieces of material are moved with perfect uniformity so that their edges are even at the completion of the stitching. These machines are used for binding slippers and for similar work requiring short. turns and binding into angles.

Machine No. 17-11, for leather stitching, has drop-feed across the arm and is provided with an adjustable attachment for neatly trimming the edge of the work; by setting out the knife, the line of its eut can be adjusted from 1/64 to 5/64 of an inch, as desired. The machines shown in the following illustrations are of the highest efficiency in the manufacture of Felt Shoes, Horse Boots, Musical Instrument Cases, Gun Cases and similar articles of irregular shape requiring very strong stitching.

Machine No. 17.5 has the usual form of drop-feed for leather; machine No. 17-12 has no under-feed, the movement of the material being effected by a special device, used in place of the ordinary presser-foot, which acts on the top surface and sets up the stitch, giving it a very superior finish and leaving the leather without mark on either side.

The work-supporting arm of these machines measures ?2 1/4 inches at its outer end and has 10 1/2 inches clear space from needle to inner end. The sewing mechanism is close to outer end, thus enabling the operator to stitch closely to edge of work.

The slight contact of the fabric with either the raised throat plate or the presser-foot enables the operator to work with facility into the centers or about the edges of concave or convex surfaces; the cylinder-bed is cut down below the line of the throat-plate so that work of irregular form can be readily passed over it.

Machine No. 17-13, illustrated above, is for stitching Cotton and Linen goods; it has left-hand feed for carrying the material up the arm, and the hem- mer is arranged for convenience of the operator in handling the work from left to right.

On Machine No. 17-14 the feed is arranged to carry the material off the arm and the position of the hemmer is reversed, each machine being most conveniently arranged for the different methods of operation. These machines are especially adapted for and extensively used in Shirt manufacture and the manufacture of Women's Undergarments; they are suitable for stitching all textile articles of a form rendering the use of a cylindrical bed desirable.

BOBBIN WINDING.

For use in winding bobbins, the balance wheel is fitted as ordered to run either tight or loose on shaft. There are two different forms of bobbin winders used with the tight balance wheel (Parts No. 5521 and No. 5523). For winding bobbins with loose balance wheel, which runs without operating machine, there are also two different forms of winder (Parts No. 5525 and No. 5527).

Machines No. 17-15 and No. 17-16 are for stitching leather and are especially useful for the manufacture of Pocketbooks, Portfolios, Belts, Hand-bags and similar articles requiring the strong, fine stitching of short seams.

These machines afford the greatest convenience for this class of work; the drop-feed is close to the outer edge of the raised throat-plate, which forms a flat. bed of most convenient size for handling the work, and a roller-presser and a roller-guide enable the utmost facility in the passage of the fabric.

Machine No. 17-16, illustrated above, has a very effective device, conveniently located under the overhanging arm, for reversing the feed and adjusting the length of stitch. By means of this combination perfect uniformity of stitch is obtained, whether feeding forward or back; the reverse feed enables tying a seam at any point desired.
