To release the balance wheel (D, Fig. 3), turn the stop motion screw (E, Fig. 3) over toward Raise the presser foot (B, Fig. 3) by means of you. It will be necessary to hold the balance wheel while loosening the stop motion screw. the presser bar lifter (C, Fig 3) to prevent injury to the foot (B, Fig. 3) and feed (A, Fig. After releasing the balance wheel, place your 3). feet upon the treadle and with the right hand turn the balance wheel over toward you. This will start the band wheel, treadle and pitman, the sewing mechanism having been disconnected. Instructions for Operating the Machines Continue the motion thus begun by an alternate pressure of heel and toe, until a regular and easy movement is acquired, and the balance wheel kept in continuous rotation by use of the feet alone. When you are thoroughly familiar with the treadle movement and can restart the machine without turning the balance wheel in the wrong direction, tighten the stop motion screw to connect the balance wheel with the stitching mechanism. Place a piece of cloth under the presser foot, let the foot down upon it, and operate the machine in this way without being threaded, until you have become accustomed to guiding the material.
FIG 3. FRONT VIEW OF THE MACHINE
It is necessary to understand the stop motion (E, Fig. 3) by which the balance wheel (D, 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. It also allows the operator to wind bobbins without removing partially sewn work and without unthreading the machine.

To Ensure Perfect Action of the Machine The balance wheel must always turn over toward the operator. Do not run the machine with the presser foot resting on the feed without cloth under the presser foot. Do not run the machine when both shuttle and needle are threaded unless there is material under the presser foot. Do not try to help the machine by pulling the fabric lest you bend the needle. The machine feeds the work without assistance. Both slides over the shuttle should be kept closed when the machine is in operation. To Remove the Shuttle Draw toward you the front slide in the bed of the machine and turn the balance wheel over toward you until the shuttle comes full under the opening. Press the forefinger of the right hand upon the shuttle ejector as shown in Fig. 4, this will raise the shuttle so that it can be easily taken out. Turn the open end of the shuttle downward and the bobbin will drop out.

To Wind the Bobbin Release the balance wheel (D, Fig. 3) by turning the stop motion screw (E, Fig. 3) over toward you. Draw to the left the knob (A, Fig. 6, page 7) and place the bobbin between the cups (B and C, Fig. 6), then release the knob. Push the bobbin winder pulley (D, Fig. 6) against the hub of the balance wheel, and turn the balance wheel until the thread guide (4, Fig. 6) moves to the extreme right. Put the spool of thread on the spool pin (1, Fig. 5). Pass the end of the thread into the thread guide (2, Fig. 5) at the top of the face plate, then up into the lower eyelet (3, Fig. 6) of the bobbin winder thread guide, into the notch (4, Fig. 6). With the thumb and forefinger of the left hand press the bobbin lightly to the left and place the end of the thread between the bobbin and the cup (C, Fig. 6) at the right. Then operate the machine the same as for sewing. When the bobbin is filled, remove it from the bobbin winder, pull the bobbin winder away from the hub of the balance wheel and turn the stop motion screw over from you to connect the stitching mechanism.

To decrease the tension, turn the FIG. 13. PERFECT STITCH thumb nut over to the left. If the tension on the needle thread is too tight, or if that on the bobbin thread is too loose, the needle thread will lie straight along the upper surface of the material, thus: The tension on the bobbin thread is regulated by the small screw (1, Fig. 7) near the point of the shuttle. To increase the tension, turn the screw over to the right. To decrease the tension, turn the screw over to the left. When the tension on the bobbin thread has been once properly adjusted, it is seldom necessary to change it, as a correct stitch can usually be obtained by varying the tension on the needle thread.

To Turn a Corner Stop the machine with the needle at its lowest point. Raise the presser foot and turn the work as desired, using the needle as a pivot. To Regulate the Length of Stitch A Stitch to Ravel Easily The length of stitch is regulated by the large thumb screw (E, Fig. 6) on the front of the arm near the bobbin winder. To lengthen the stitch, turn this screw over to the right. To shorten the stitch, turn this screw over to the left. To Regulate the Pressure on the Material For ordinary family sewing it is seldom necessary to change the pressure on the material. If sewing fine silk or flimsy material, lighten the pressure by turning the thumb screw (A, FIG. 5) on the top of the machine over to the left. To increase the pressure, turn the 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. 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. 15. To Sew Flannel or Bias Seams Use a short stitch and as light a tension as possible on the needle thread so as to leave the thread loose enough in the seam to allow the goods to stretch if necessary.

HINTS The Belt See that the belt is not too tight; it should always be tight enough not to slip. If too loose remove the hook at one end, shorten the belt and rejoin. Machine Working Heavily. 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. Breaking of Needle Thread. If the needle thread breaks it may be caused by: Improper threading. Tension being too tight. The thread being too coarse for size of needle. The needle being bent, having a blunt point, or being set incorrectly.

To Oil the Machine To ensure easy running, the machine requires oiling and if used continuously it should be oiled each day. With moderate use all occasional oiling is sufficient. Oil should he applied at each of the places shown by arrows in Figs. 16 and 17. One drop of oil at each point is sufficient. Oil holes are provided in the machine for bearings which cannot be directly reached. To oil the mechanism under the slide, draw the front slide (see Fig. 16) toward you and after removing the lint and dust which may have accumulated, put a few drops of oil on the wick which is retained in the hole in the bed of the machine. The slide should then be closed. On the front of the machine at the left is a small plate or cover (see Fig. 16) fastened by a screw; loosen the screw, turn the plate upward and fasten by tightening the screw; turn the balance wheel slowly and oil the movable parts inside, then turn the cover down and fasten it as before.

To Oil the Machine continued. On the back of the arm is a round plate or cover, fastened by a thumb screw. Loosen the screw, turn the plate upward and fasten by tightening the screw; turn the balance wheel slowly and oil the moving parts inside, then turn the cover down and fasten it as before. To reach the parts underneath the bed, the kilt must be thrown off the band wheel on the machine stand. Or this purpose a belt shifter is placed at the front of tile band wheel. By pressing the belt shifter lever to the left and working the treadle meanwhile, the belt is released and the machine can then be turned back on its hinges. The places to be oiled are indicated in Fig. 17, by arrows pointing to the oil holes and bearings. To oil the stand, put a drop of oil the centres on which the band wheel and treadle work, and both ends of the pitman rod, which con-

INSTRUCTIONS FOR USING THE ATTACHMENTS FOOT HEMMER -- Hemming Raise the needle to its highest point. Remove the presser foot and attach the foot hemmer in its place (see Fig. 18). Clip off the right hand corner of the cloth, so that it will take the roll easily, turn up the edge about a quarter of an inch, insert it in the mouth of the hemmer and draw or push it along until under the needle. Then let down the presser bar and after taking two or three stitches, draw gently on the ends of the threads to help the work along till the feed catches it. In order to produce a smooth even hem, the mouth of the hemmer must be kept just full. Fig. 18 shows also what is known as a bag seam or fell, made by passing two pieces of fabric through the hemmer together and hemming them down. FOOT HEMMER Hemming and Sewing on Lace Start the hem as previously explained, and when it is well started, raise the needle to its highest point. Raise the hemmer to relieve its pressure on the hem, pass the end of the lace through the slot in the side of the hemmer, under the back of the hemmer and over the hem, as shown in Fig 19. Take care that the hem is not displaced in the hemmer and that the needle goes down through the lace and hem together. Then let down the presser bar and guide tile lace over the front of the hemmer, keeping it well into the slot.

FOOT HEMMER -- Felling The two pieces of cloth to be felled should be laid one over the other, right sides together, the edge of the under piece being a little farther to the right than the upper piece. 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). 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).

ADJUSTABLE HEMMER -- Hemming Remove the presser foot and attach the adjustable hemmer in its place as shown in Fig. 22. This hemmer will turn hems from 3/16 inch to 15/16 in. wide The adjustment is made by loosening the thumb screw on the hemmer and moving the scale to the right or left until the hem turned is of the desired width. Place the cloth under the hemmer and draw the edge toward the left under the scale, as shown in Fig. 22. Draw the edge of the cloth 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. ADJUSTABLE HEMMER -- Wide Hemming To make a hem more than 15/16 inch wide, loosen the thumb screw in the hemmer and move the scale to the right as far as it will go, then swing it toward you as shown in Fig. 23, and tighten the thumb screw. Fold and crease down a hem of the desired width; pass the fold under the extension at the right of the hemmer, and the edge into the folder as shown in Fig. 23, and proceed to stitch the hem.

BINDER -- Binding Remove the presser foot and attach the binder in its place. Pass the binding through the scroll of the binder and draw it back under the needle. Place the edge of the goods to be bound between the scrolls of the binder and draw it under the needle. Lower the presser bar and sew as usual. To make French folds proceed as directed for binding except that the fold is stitched on to the face of the material instead of on the edge (see Fig. 24). After loosening the binder set screw and adjusting the binder the line of stitching can he brought, nearer the centre, this being more effective when making French folds.

FIG. 24.

Table of Contents 19
TUCKER Remove the presser foot and attach the tucker in its place. The width of the tuck is determined by the scale of figures nearest the needle, which shows in eighths and sixteenths of an inch the distance of the edge of the fold from the line of stitching. The crease or mark for the second and following tucks is determined by the scale nearest the operator and this is set by the line in front of the needle hole in the presser foot. For blind tucks without spaces, adjust the scale nearest the operator so that the figure opposite the line on the presser foot will be the same as that at which the guide is located on the scale nearest the needle. To make spaces between the tucks, move the front scale farther to the left until the desired space is obtained. Having adjusted the scales for tuck and space as desired, fold the material and crease by hand; pass the folded edge between the spring and spur near you, then between the two blades of the second scale, and back under the presser foot; draw to tile right against the guide, lower the presser bar; see that the lever for the needle clamp to strike is in its backward position so as to form a crease for the next tuck, then proceed with the first tuck. For the second tuck, fold carefully at the crease made by the spur and place the edge of the first tuck underneath and against the spur at the left. The spur will serve as a guide and will also make a distinct crease for the next tuck. Always place the last tuck against the spur to ensure perfect work. When making the last tuck, the lever upon which the needle clamp strikes while tucking should be raised to its highest point; while the lever is in this position no crease for a succeeding tuck is made upon the goods.

Ruffler -- Principal Parts continued. H -- RUFFLING BLADE--the upper blue steel blade with the teeth at the end to push the material in plaits up to the needle. J -- SEPARATOR BLADE--the lower blue steel blade without teeth, which prevents the teeth of the ruffling blade coming into contact with the feed of the machine, or the material to which ruffling or plaiting is to be applied. To Adjust the Ruffler for Gathering The adjusting finger (F, Fig. 27) is not intended for gathering and should be moved forward or away from the needle, as shown in Fig. 27. Raise the adjusting lever (E, Fig. 27) and move it to the left so that the projection (D, Fig. 27) will enter the slot marked "1" in the adjusting lever (E) when the lever is released. The ruffling blade will then move forward and back once at every stitch. Insert the material to be ruffled between the two blue blades, following the line 2 in Fig. 26. Draw the material slightly back of the needle, lower the presser bar and commence to sew. To make fine gathering, shorten the stroke of the ruffling blade by turning the adjusting screw (C, Fig. 27) upwardly, also shorten the stitch. To make full gathering, lengthen the stroke of the ruffling blade by turning the adjusting screw (C) downwardly, also lengthen the stitch. By varying these adjustments, many pleasing varieties of work can be accomplished.
To Attach the Ruffler to the Machine Raise tile needle bar to its highest point and remove the presser foot. Attach the ruffler foot, (A, Fig. 26)) to the presser bar by means of the thumb screw, at the same time placing the fork arm (B, Fig. 26) astride the needle clamp as shown in Fig. 27.

Piping a Ruffle Insert the material to be ruffled between the two blue blades, following the line 2, in Fig. 26. This material must not be over 1 1/4 inches wide, as it is carried through the ruffler with the finished edge of the ruffle to the right of the attachment as shown In Fig. 30 To Adjust the Ruffler for Plaiting
Raise the adjusting lever (E, Fig. 31) and move it to the right so that the projection (D, Fig. 31) will enter the slot marked "6" in the adjusting lever when the lever is released. The ruffling blade will then move forward and back once at every six stitches. To adjust the ruffling blade to make a plait once at every twelve stitches, place the adjusting lever (E, The material for piping must measure about Fig. 31) so that the projection (D) enters the 1/4 inch wide when folded in the centre and slot marked "12" in the adjusting lever. Insert is usually cut on the bias. Place the piping the material to be plaited between the two material in the ruffler, following the line 4, in blue blades, following the line 2, (Fig. 26).

To Adjust the Ruffler for Group Plaiting and Gathering The ruffler can be adjusted for group plaiting by lifting the adjusting lever (E Fig. 32) and moving it to the right so that the top of the projection (D, Fig. 32) engages the small slot indicated by the star on the adjusting lever. This should be done at the points where you wish to make the space between the plaits. The ruffler will then stop and plain stitching will be made. When the desired space has been made, adjust the lever (E) so that the projection (D) enters either the slot marked "6" or the slot marked "12." By alternately making groups of plaits and plain spaces, as shown in Fig. 32, very attractive work can be produced. To Oil the Ruffler Occasionally apply a drop of oil to the working parts of the ruffler at each of the places indicated by arrows in Fig. 32. After oiling, operate the ruffler on a waste piece of material to prevent the oil soiling the work. If the ruffler does not plait evenly, a drop of oil may remedy the trouble.
