[. . . ] 15 INSTRUCTIONS FOR OPERATING THE MACHINE Raise the presser foot (2, Fig 3) by means of the presser bar lifter (3, Fig. 3) to prevent injury to the foot (2, Fig. FRONT VIEW OF THE MACHINE It is necessary to understand the stop motion (5, Fig, 3) by which the balance wheel (4, Fig. 3) can be released when required, thus enabling the operator to become proficient in the use of the treadle, and permitting the winding of bobbins without running the stitching mechanism. [. . . ] If sewing fine silk or flimsy material, lighten the pressure by turning the thumb screw (13, Fig. 5) on the top of the machine over to the left. To increase the pressure, turn this screw over to the right. The pressure should be only heavy enough to prevent the material from rising with the needle and to enable the feed to move the work along evenly; a heavier pressure will make the machine run hard. To Sew Flannel or Bias Seams Use a short stitch and as light a tension as possible on the needle thread so as to have the thread loose enough in the seam to allow the goods to stretch if necessary. A Stitch to Ravel Easily can be made if desired, by having the tension on the needle thread so light that the bobbin thread will not draw into the goods but lie straight, as shown in Fig. Table of Contents 14 Previous Page | Next Page Sewing Machine No. See that the belt is not too tight; it should always be tight enough to not slip. If too loose, remove the hook at one end, shorten the belt and rejoin. If the machine runs hard after standing idle for some time, use a little kerosene in the oiling places. run the machine rapidly, then wipe clean and oil. The places to be oiled are indicated in Fig. Stitch them together, using the hemmer as a presser foot, the front end of the hemmer forming a guide for the edges of both pieces, the upper piece being guided by the inside and the under piece by the outside of the projecting front of the foot hemmer (see Fig. 20 Table of Contents 20 Previous Page | Next Page Sewing Machine No. 15 Then open the work out flat, wrong side up, the edges standing up straight, and taking the edges near the beginning of the seam in the right hand and the ends of the threads in the left hand, draw the edges into the hemmer which will turn them as in hemming. Guide the second row of stitching by following the first row with the inside of the projecting front of the foot hemmer (see Fig. 21 Table of Contents 21 Previous Page | Next Page Sewing Machine No. 15 ADJUSTABLE HEMMER - Hemming Remove the presser foot and attach the adjustable hemmer in its place as shown in Fig. This hemmer will turn hems from 3/16 inch to 1 in. The adjustment is made by loosening the thumb screw on the hemmer and moving the slide to the right or left until the hem turned is of the desired width. Enter the edge of the cloth into the hemmer under the scale and draw it back and forth until the hem is formed, stopping with the end under the needle. Lower the presser bar and commence to sew being careful to so guide cloth as to keep hemmer full. [. . . ] The material for piping must measure about 1/4 inch wide when folded in the centre and is usually cut on the bias. Place the piping material in the ruffler, following the line 4, in Fig. 26, with the folded edge of the piping to the right. The material to which the piping and ruffling are to be sewn should be folded on the edge and inserted in the ruffler following the line 5, in Fig. [. . . ]
