JACOB S. ALTER, OF LEAVENWORTI-I, KANSAS.

Specification forming part of Letters Patent No. 117,716, dated August 8, 1871.

To all whom t may concern:

Be it known that I, J A0013 S. ALTER, of Leavenworth, in the county of Leavenworth and State of Kansas, have invented a new and Improved Combination Sewing-Machine Attachment 5 and I do hereby declare that the followingI is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this speciication.

My invention consists in an improvement upon the gauging and plaiting attachment patented to me May 3, 1870, and will be first hereinafter fully described in connection with all that is necessary to its full understanding and then clearly pointed out in the claim.

Figure lis aplan view of the gauge and plaiter with the extension of the gauge-plate. Fig. 2 is a transverse section of the same on the line w. x, showin g the adjustment of the goods when used as a cloth-guide and for sewing without basting the goods. Fig. 3 is a similar section, showing the adjustment of the goods for making threeply tucks. Fig. 4 is a similar section, showing the adjustment of the goods in making wide henis. Fig. 5 is a plan view, showing the adjustment of the goods for making the three-ply tucks, shown in section, Fig. 3. Fig. Gis a plan view, showing the adjustment for making two-ply tucks. Fig.

` 7 is a plan view, showing the application of a binder to the gauge and plaiter. Fig. .8 is a front elevation of Fig. 7. Fig. 9 is a section of Fig. 7 on the line y y. Fig. 10 is a plan view of the gauge and plaiter, showing the attachment of a ruflier to it 5 and Fig. ll is a front elevation of Fig. l0.

Similar letters of reference indicate corre sponding parts.

Ihe plate A, with slot B, cloth-guide G, studs E, and the screw F, and also the plate Gwith slot H, scale I, and the grooves J, are the same as represented in the aforesaid patent granted to me, and thus arranged afford an excellent attachment for guiding the goods to be stitched togcther, plaited, or tucked, and for many other kinds of work; but, for use onsome machines, and for many kinds of work, I found the said attachment to be greatly improved by the application of the extension K of the plate A beyond the cloth-guide C, under and beyond the projecting part of the plate G, said extension forming a continuous surface level with that of plate A l as far as the plate G is to extend, or beyond, over which surface the cloth to be sewed passes and is held up to the plate G so as to be much more subject to its action and that of the oblique guiding-ribs on the lower surface than it can be when lying on the table or plate of the machine, and in some machines the tables are so arranged that the plate G cannot be brought to the cloth at all. In such cases the attachment is useless without the said extension, but with it it is not only serviceable in such machines, but is made better for all others, and is highly useful for stitching shirtbosoms, making two-ply and three-ply tucks, boxplaiting, hemming, and preparing seams for felling; it is also very serviceable in stitching goods together without basting.

The sectional Fig. 2 represents the manner of using the instrument for sewing' without bastin g.

lhe lines a represent the two plies of cloth which are kept snugly against the guide C by the ribs b on the under side of the plate G. The action of these ribs may be varied bythe temper-screw F and nut thereon, and the spring I to keep the edges of the cloth more or less snugly against the guide C, as may be preferred. The sectional Fig. 3 and the plan Fig. 4 represent the manner of using the instrument for making three-ply tucks, for which it possesses the highest merit. In this case the plateAis adjusted as close to the presser and needle as it can be, for which the notch J is provided t0 let the presser enter in order that the seam may be as close to the fold d as possible. The plate G is then adjusted as far beyond the guide C as the width ofthe tuck is to be and the folded cloth is applied with the fold d against guide C; then the upper piece is folded back over the end of plate G, as shown at e, and stretched down to the fold d, as indicated by the line f. In this case the pressure of the oblique ribs b keeps the fold d against the guide C with great accu-l racy, and the end 'of plate G guides or regulates the fold e of the upper ply of the cloth. The plan view, Fig. 6, represents the manner of using the instrument for making the ordinary two-ply tucks. The guide C is placed as far away from the needle as the required width of the tucks g, and the end of plate G is adjusted as far beyond the needle as the required width of the spaces h between the tucks, and its end acts as a guide upon the cloth inside the seam of the last tuck formed, as shown at i, while the fold of the tuck being formed runs along the cloth-guide C.

The manner of making wide hems is indicated in the sectional view, Fig. 4. The edge of the cloth is turned over and placed against the guide C, as at 7c,- the plate G is projected as far as the required width of the hem and the cloth folded back over it at Z and stitched down upon the edge n the same manner as in making three-ply tucks.

Besides these, and other operations which may be performed by this improved attachment, it is made serviceable for binding and ruffiing by the application to it of certain other attachments, which I will now proceed to explain.

For binding, a plate, M, with a hook-shaped end, N, turned upward, is supported in front of the platesA and G, with the hooked end a little in advance (to the left) of the guide C and its upper surface on the level of the upper surface of the plate Afand its extension K being thus supported by a plate, O, to the under side of which it is confined by hooks or lugs P on it, so shaped as to embrace the edges of said plate and hold it so that it can be adjusted forward or backward parallel with the fronts of plates A and G,

and be held in any position by the friction ofthe parts or by a clamp or binding-screw. The plate O is secured to the plates A and G by being inserted between them and between the lugs E, at the front of plate A, passing beyond the clampscrew F, for which it has a long slot, Q,provided in the part entering between said plates, between which it is bound by the said screw and its nut. This binding attachment being so applied, the lower part of the folded binding is placed under the hook N, as shown at oni/,while the edge of the cloth is placed above the hook and the upper part of binding over said edge.

Thus arranged,the work can be done in the most satisfactory manner, requiring but verylittle attention of the operator in adjusting the binding on the edge of the cloth in advance of the instrument, which insures the exact adjustment of the binding by reason of the natural tendency of the feed to cause the lower part to work under the cloth and draw oif from the upper side, being counteracted by the bottom of the hook acting on the edge of the binding, keeping it in the position required.

This mode of attaching the binder is applicable for attaching rufiiing or other instruments also, and by it I may utilize the plates A and G for use in connection with various other instruments.

Figs. 10 and 11 show a ruiiling attachment, composed of the plates o and pand bindingscrew q, attached in the same way. Fig. 1l also shows the manner of adjusting the cloth for rufling.

For sewing-machines, in which the work has the side movement instead of the front, for which the attachments here shown are adapted, the said attachments will be arranged reversely.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The plate M having upward hook N, and the plate O having lugs P, combined with and applied to plates A, K, E, and G, as and for the purpose specified.

The above specification of my invention signed by me this 30th day of May, 1871.
