FABRIC CONNECTION.

Application filed June 8, 1911.

To all whom it may concern Be it known that 1, CHARLES A. HANSEN, a citizen of the United States, and a resident of Elizabeth, Union county, New Jersey, have invented a new, useful, and Improved Fabric Connection, of which the following is a specification.

My invention relates to the art of sewing fabrics and its object is to produce a new and improved connection for securing fabrics together.

One of the embodiments of my invention is illustrated in the accompanying drawings in which Figure 1 shows in plan view the clothplate of a sewing machine and one form of attachment by which the fabric connection of my invention may be produced. Fig. 2 is a vertical section of the cloth plate of Fig. 1 showing the needle and the presser foot of the machine as well as the attachment in side elevation. Fig. 3 is an end view of the device looking in the direction of the arrow at the right of Fig. 2. Fig. 4 is a section of the device on the line 4-4: of Fig. 2. Fig. 5

is a section of the device on the line 5-5 of Fig. 2. Fig. 6 is a longitudinal section of the device showing one of the folders thereof in side elevation. Fig. 7 is a plan view of two fabrics and my improved connection therefor, as they are disposed immediately after the sewing process. Fig. 8 is an enlarged cross-section of the fabrics as shown in Fig. 7. Fig. 9 is a plan view of the fabrics shown in Fig. 7 after they have been relatively moved into the same Plane and pulled apart- Fig. 10 is a section similar to that of Fig. 8, but with the fabrics moved into a common plane. Fig. 11 is a section similar to that of Fig. 10, with the fabrics pulled apart and showing the lower surfaces of the fabrics and the connection in perspective. Fig. 12 is a longitudinal section of the edge-portions of the fabrics disposed as shown in Figs. 7 and 8, showing the manner of stitching.

A form of attachment by the use of which my fabric connection may be made is illustrated by Figs. 1-6 inclusive.

The reference character 1 indicates the cloth plate of a sewing machine of any suitable type. For producing the particular fabric connection shown by Figs. 7-12 inclusive, I may use the VVilcoX & Gibbs automatic sewing machine adapted to make loose Specification of Letters Patent.

stitches of constant length. I do not wish to be limited, however, to this particular mach ine, but desire it to be understood that myinvention contemplates the use of any machine suitable for use in the production of a fabric connection set forth in the claims. The characters 2 and 3 in Fig. 2 indicate the needle and the presser foot respectively of the sewing machine. Adjustably secured to the cloth plate 1 and in position to discharge the fabric edge portions, properly folded, 1nto position to be pierced by the needle is the attachment previously referred to, said attachment comprising two folders 4: and 4t soldered or otherwise suitably secured to a base plate 5, which in turn is secured to a bracket 6, adjustably held on the cloth plate by the engagement with the walls of an elongated slot therein of a set screw 7, screwthreaded into the cloth plate. The base plate 5 is substantially triangular in shape and is set with one edge abutting the top of the cloth plate, the pointed end being near the needle. Secured along the converging edges of this plate are the folders 4 and 4-, the feed ends thereof being spaced apart to a greater extent than the discharge ends thereof and said discharge ends being close together and near the machine needle so that the folded fabric discharging from one folder will be above and in near relation to that discharging from the other folder and the folds will be pierced by the needle before their relative positions are disturbed. Each folder is similar in conformation to its associated folder except that the convolutions and surfaces of the one extend in directions opposite to those of the other. One may be said to be a right-handed folder while the other is left-handed. A description of the one, as will be readily understood, is applicable also to the other. Each folder is preferably formed from a sheet-metal plate by bending. Theplate is first bent in the region of the line 8, to form at the feed end two guide walls for the reception of the fabric to be operated upon, these walls being extended near said end to form wings 9. The walls are substantially parallel and near the base plate 5 they are bent or bulged outwardly to form an exterior convex surthe folder substantially into the forrn ofa. {the folded edge portion of one above the spiral of gradually decreasing diameter.

The inner wall of the two guide walls is cut away so as to present an edge 10, (Figs. 3, 5 and 6), this edge extending longitudinally toward the discharge end of the folder and cutting across the region 8 near the line H of Fig. 2, which region now continues its path toward said discharge-end inthe form of an edge l.v The base plate is curved, as will clearly be understood, t0v

conform to the variation'in diameter of the spiral portion, formed in the manner described. The region 8 at the feed end'of "the folderis in contact with the base plate" 5. At the linei5 5 of Fig.2, as will be seen by an inspection of Fig. 5, it is at a distance I Fig. 2,-it has merged'into the edge 10,

shown in Fig. l. 'lhe spiral conformation of the portions described serve partially to 7 turn over' upon the face of the fabric the fabric'edge-portion which is fed between the guide walls near the region 8'thereof.- The outer guide wall is'not cut away as was the;

- inner wall, but is provided with an extension 11 near the discharge end of the folder,

' which, is folded over, externally of the 'spirally-conformed portion previously de--- scribed, substantially into the form of a spiral of graduallydecreasing diameter, the direction ofthe last-mentioned spiral being opposite to that. of the first-mentioned spiral. The end of thelspiral, formed'by the 5 bending of the extension ll, nearest to the feed end of the folder-is marked by the substantially spiral edge 12 of saidextension;

which; edge as it approaches the discharge end gradually merges into the longitudinal edge 12. As the fabric is fed from the feed end toward-the discharge end of the folder,

while the edge portion thereof is being turned over by the portion 8 as previously set forth to formthe fold 13, a portion of therfabric at a distance from the edge, is

engaged by the spiral edge 12'and the spiral convolutions 'ofthe extension 11, which pro duce a fold 14 in the fabric and turn said fold 14 over and upon the oppositely turned fold 18,'thus forming a fold 15.- Upon dis- 1 charging from the device therefore the fabric has three superposed folds, the first due to theconvolution of theportion 8, the secthe spiral convolution of the extension 11, so.

as to turn the second fold over-anduponthe first fold. Two of these folds, as will be 0nd due to the engagement of the spiral edge 12 with the fabric, and the third due to seen, face in one direction While the third faces in the opposite direction. Since the device illustratedcomprises two folders, one being oppositely convoluted with respect to the other, when a fabric is fed into each folder, said fabrics are folded over in the manner described and" are discharged with oppositely folded edge portion of the other.

Thuspositioned,they are pierced by the needle and secured together as they move along, by a loose stitching, leaving the sewing machine secured together and disposed V as shown by Figs. 7 and 8. The fabrics are relatively rotated about the secured edge portions into a common plane as shown by Fig. 10. The folds are now loosely held and are not necessarily closely associated. Upon pulling the fabrics apart, the folds, as will be apparent,,are moved into close relationship, as shown in Figs. 9 andll. The upper surfaces of the fabrics, When thus operated single sewing threadwhich binds thefabrics together may easily be understood from an inspection of Fig. 12. This particular stitching is formed by the operation of a particular type of sewing machine. It is to be understoodhowever, that I do not wish to limit my invention to any particular kind of machine, and hence to any particular kind {of stitch, but my invention comprises the use of any machine and any form of stitch for securing the suitably folded edge portions of fabrics in spaced relation.

For instance, the two folders may be oppositely disposed in substantially the same plane, their discharge ends suitably separated to guide the fabric folds into the path of operation of the needle of a fagot machine; in this case the fabrics are'folded as previously described and secured in separated relation by a fagot stitch.

' My improved fabric connection is suitable for use many art in which it is desired to sew fabrics together With their edges separated. It is therefore useful in'the manufacture of umbrellas or parasols, especially such as have a border portion secured to the main central portion but slightly spaced therefrom. Heretofore it was necessary in the manufacture of such para'sols to fold over and stitcha hem'on each piece of fabric and thereafter to stitch the two hemmed edges together by a'loose stitch. It will be seen that my connection accomplishes the sameresult in one operation, necessitating the use of only one machine and one conproximately three times as much thread. The time consumed in making my fabric connection is also, as will be apparent, very considerably less than that needed formerly for connecting fabrics together in spaced relation. My connnection is furthermore, stronger and neater in appearance than former similar connections.

1. The combination of a plurality of fabrics, their edge-portions being substantially parallel to and spaced from each other and the edge-portion of at least one of said fabrics comprising a plurality of layers of fabric, and a single thread piercing said edge portions and constituting the means both to secure said fabrics together and to hold said layers in place, said thread passing through a single longitudinal series of needle perforations through the edge of each fabric.

2. The combination of a plurality of fabrics, their edge portions being substantially parallel to and spaced from each other and the edge portion of each comprising three folds, two of which face in one direction, the third facing in the opposite direction, and stitching piercing said edge portions and serving both to secure said fabrics together and to hold said folds in place.

3. The combination of a plurality of fabric portions, their contiguous marginal edges being spaced apart and inturned to form folds located on the under side of each fabric portion and a single thread holding said parallel and spaced from each other and the edge portion of each comprising three folds, two of which face in one direction, the third facing in the opposite direction and the edges of two of said folds forming the edge of each fabric and stitching piercing said edge portions and serving both to secure said fabrics together and to hold said folds in place.

5. The combination of a plurality of fabrics, their edge portions being substantially parallel to and spaced from each other and the edge portion of each being inturned to form folds located on one side of the fabric, the visible surfaces of the folds being the same as the surface of that side of the fabric on which said folds are located, and stitching piercing said edge portions and securing said fabrics together.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
