Specification of Letters Patent.

Patented Oct. 2'7, 1908.

Application filed February 6, 1902. Serial N 0. 92,883.

To all whom it may concern:

Be it known that I, GEORGE JOHN STE- VENS, a subject of the King of Great Britain and Ireland, formerly of Bradford, county of York, England, now residing at 25 East Lake road, Loughborough Junction, London, S.E., England, have invented a certain new and useful improvement in a combined presserfoot and guide for sewing-machines for producing blindstitching and fancy and ornamental stitching and the like, of which I declare the following to be a full, clear, and exact specification.

My invention relates to a combined presserfoot and guide for'sewing machines for producing blind-stitching, while at the same time not interfering with the use of the machine for plain stitching, the object of my invention being to produce a device that shall be of extreme simplicity in construction, and both easy and inexpensive to manufacture; easy to secure to and readily adjustable upon any ordinary sewing machine, and capable of use upon the same; that will perform the work of blind-stitching, hemmin and the like, with the usual and ordinary Iock-stitch of the machine, and that will perform this work upon substantially all kinds of material, however thick or thin they may be.

The novel construction, combination, and arrangement of parts constituting my invention will be hereinafter fully described, pointed out in the appended claims, and illustrated in the accompanying drawings, which form a part of this specification, and in which:-

Figure 1 is a perspective view showing my combined presser-foot and guide in place upon a sewing machine, with a piece of work folded and being stitched. Fig. 2, is a perspective view of the combined presser-foot and guide by itself, showing the presser-bar in dotted lines. Fig. 3 is a side elevation of the parts shown in Fig. 2, the inner foot being depressed somewhat to form the guide. Fig. 4 is a view showing the bottom of the presserfoot and guide. Fig. 5 is a front cross sectional view of the same, and Fig. 6 is a plan view of the same showing the parts slightly separated.

In carrying my invention into effect I provide a block A, which is so constructed as to be readily attached to the presser-bar B of the sewing machine by a suitable set-screw 7) instead of the ordinary presser-foot. Upon the outer side of this block A, which is provided with a rearwardly projecting extension A, I secure a presser-foot C, the inner side of which, that is to say the side next to the needle D, is cut away somewhat to form a recess 0, through which the needle D may pass.

cure another presser-foot E, provided with a recess 6, on its outer face next the needle D. I preferably construct the block A with the two vertical ribs a, a located opposite to each other upon the rearwardly projecting extension A and about midway of its length, and just back of the point of attachment to the resser-bar B, and construct the two pressereet O, E, with corresponding grooves or channels, 0 e permitting engagement with the ribs a, a just mentioned. The two presser feet O, E, may be attached to thelock A with set screws 0 6 or in any other desired way, that will permit of the necessary adjustment hereinafter mentioned.

I provide the two presser feet O, E, with vertical slots 0 6 through which the set screws 0 6 that secure the presser feet 0, E, to the block A may pass, permitting the presser feet 0, E, to be adjusted up and down upon the block A, and to be secured in any desired position thereon. Back of the set screws 0 6 that secure the presser feet O, E, to the block A, I provide adjusting screws F, G, which pass through screw threaded holes f, g, in the presser feet O, E, and have their bearing against the adjacent face of the rearwardly projecting extension A, of the block A.

- In carrying my invention into operation upon machines where the work is fed from the o erator toward the back of the machine, the 0 0th H to be blindstitched is folded as shown in Fig. '1, and placed under the outer presser foot O, the cloth I, to which the first piece H is to be blind-stitched, being beneath the folded piece and laid flat upon the machine; or the two pieces of cloth H, I, to be joined, may both be folded separately and laid the one'upon the other, both folds being placedunder the outer presser foot O. The set-screw 6 binding the inner presser-foot E to the block A is then loosened, and the inner presser-foot E allowed to drop to near the bed-plate K of the machine, in which position it is then secured to the block A, by

tightening the set-screw e.

To the opposite side of the block A, I se- The inner presser-foot E, in the construction above described, serves as a guide for the Work, which is fed against it, the outer face of this resser foot E, that is, the face next the needle D, being almost in line with the inner face of the needle D, that is to say, the face toward the arm of the machine, so that as the work is fed to the machine, and against the inner presser foot E, the needle D must pass more or less exactly through the center of the fold of the cloth H and not entirely through its entire thickness, from side to side of the cloth.

By simply turning the adjusting screw G, at the rear of the inner presser foot E, the one way or the other, the point of the presserfoot E may be moved more closely to, or away from the needle D, thus giving the adjustment necessary for sewing cloths of va rying thicknesses. It will be obvious that instead of making the inner presser foot E serve as the guide, that in cases where the work is fed from the back of the machine toward the operator, that the outer presserfoot 0 may be used as theguide, the work in this case being fed against it from the other side. The presser foot C in this case will be lowered to near the bed-plate K of the machine, in order to serve as the guide, and secured in this position by the set-screw 0 while the point of the foot 0 will be adjusted toward or away from the needle D, by turning the adjusting screw F the one way or the other. The work will then be folded and placed under the foot E, which will serve as the presser-foot. Or, if preferred, the sewing machine may be provided with two presser-bars side by side, and the two presserfeet C, E, may be attached thereto, instead of to the block A above described. As it is essential that the presser-foot that acts as the guide should lie so close to the needle D that the latter when making the stitch can not pass entirely through the thickness of the cloth operated upon, as otherwise the stitch would show upon both sides of the cloth, I construct the recesses c, e, in the faces of the presser-feet, just sufficiently large enough to take the bulge of the cloth as the needle passes through it. If either too large or too small, irregular stitching will be the result.

In order that the feed of the machine, Where an L shaped feed is used, may not rub against the presser foot E, and injure either the foot or the feed, or cause vibrations that might effect the regularity of the stitching, I form a small recess 6 in the bottom of this foot as is clearly shown in Fig 4.

Havin now fully described my invention, what I c aim as new and desire to secure by Letters Patent is 1. A blind stitching device for sewing maeach of said feet being vertically adjustable,

whereby either of said feet may act as a presser foot. v

2. In combination, two feet attached to a presser bar in different horizontal planes and one of them having a vertical recess in its edge to receive the bulge of the cloth and means for adjusting the said recessed foot towards and from the needle, the said presser feet maintaining a permanent relation to each other when adjusted substantially as described.

3. In combination, two feet attached to the presser bar, each being vertically and laterally adjustable independently of the other whereby each may be adjusted to a higher position in relation to the other and each may be adjusted towards the needle and each having a vertical recess in its edge near the needle, substantially as described.

4. A blind-stitching device for sewing machines, comprising a block adapted to receive and be secured to the presser-bar of the machine, a rearwardly projecting extension upon the said block, two feet secured to the extension of the block, and means for adjusting the said feet vertically upon the said extension said means serving to fix the said presser feet rigidly in position.

5. A blind-stitching device for sewing machines, comprising a block adapted to receive and be secured to the presser-bar of the machine, a rearwardly projecting extension upon the said block, two feet secured to the extension of the block, means for adjusting the said feet vertically upon the said extension, and means for adjusting the said feet nearer to or away from each other and the needle of the machine said means serving to fix the said presser feet rigidly in position.

6. A blind-stitching device for sewing machines, comprising a block adapted to receive and be secured to the presser-bar of the machine, a rearwardly projecting extension upon the said block, vertical ribs upon the said extension, and two feet adjustably secured to the said extension with means for fixing the presser feet rigidly in position, and having grooves or channels for engagement with the said ribs.

In witness whereof I have hereunto set my hand in presence of two witnesses.

GEORGE JOHN STEVENS.
