This invention is concerned with improvements in or relating to the attachment of beadingor like strips to articles consisting of sheets of material arranged at an angle with relation to each other and secured together attheir edges to form a corner, and is particularly, but by no means exclusively, concerned with the attachment of beading or like strips to suitcases, hat bags or the like during the manufacture thereof.

During the manufacture of suitcases'or the like, a beading or fillet strip has heretofore sometimes been attached between the parts of the work where they are sewn together in such a manner that the bead of the strip projects outwardly beyond the junction of the parts and lies on the outside of the case or the like. It thus hides the line formed where the parts abut and provides an ornamental bead extending around the work, the beading strip being usually formed of material having a color different from that of the case. Such a heading strip is usually formed by folding a strip of thin material over a cord, which may be of twisted paper, and cementing the adjacent faces of the material together so that the cord lies along and within the folded edge of the strip to form a bead on the strip and the cemented-together portions of the strip provide a flange for attaching the beading strip to the case.

The beading strip has heretofore been attached to the bottom of a case or bag before the bottom and sides of the article are joined together, by sewing the flange of .the beading strip to the projecting margin of. a thin covering layer cemented to the bottom of the case. After this sewing operation the covering layer is bent around the edge of the bottom and cemented to the other face thereof adjacent the edge, the head portion lying just outside the edge of the bottom. 'The sides or ends and bottom of the case are then joined together to form the completed article by sewing them together in a curved hook needle lockstitch sewing machine, especially designed for the purpose, examples of such machines being disclosed in United States Patent No. 1,695,718 to Fred Ricks and Robert Gow. Reid, dated December 18, 1928, United States Patent No. 1,894,399 to George Hazelton dated January 17, 1933, United States Patent No, 2,029,099 to Joseph Gouldbourn, dated January 28, 1936, and United States application Serial No. 749,594 of Joseph Gouldbourn and Thomas Aubrey Kestelhfiled October 23, 1934, corresponding to British Letters Patent No. 430,984.

The principal object of the present invention is to provide a method and means adapted for use in a sewing machine of the type above referred to whereby a heading strip and the parts of a suitcase or like article may be sewn together at a single sewing operation by a single seam.

With thisand other objectsin view, there is provided in the various embodiments of the invention hereinafter described, guiding means adapted for use in sewing machines of the type .above referred to for guiding a beading strip to the sewing point along with and between adjacent edge portions of the work, whereby the flange of the beading strip is secured between the edges of the work by the same operation that secures the portions of the work together.

The several features of the present invention will be apparent to those skilled in the art from the following description taken in conjunction with the accompanying drawings in which Figure 1 is a perspective view of one of said illustrative embodiments; Figures 2 and 3 are respectively sectional views along the lines 2-2 and 3--3 of Figure 1; Figure 4 is a sectional view of a second illustrative embodiment of the invention; Figure 5 is a front elevation of a third illustrative embodiment of the present invention; Figure 6 is a partial sectional elevation of the same on an enlarged scale, taken along the line 6-6 of Figure 5; and Figure '7 is a plan view of the embodiment illustrated in Figures 5 and 6.

In the illustrative embodiment shown in Figures 1 to 3 an external Work support I, similar to the work support referred to as 49 in Serial No. 749,594 has two work-supporting faces 2 and 4 arranged at right angles to each other for supporting, in conjunction with a work-entering horn such as that referred to as 53 in the prior specification last mentioned, two pieces of a case or bag (e. g., a bottom and an end of a case) which are to be sewn together at right angles to each other. As will be understood from a consideration of Serial No. 749,594 the parts of the work to be sewn together are fed along the work support in a direction extending from right to left thereof to cause the stitching to proceed along the work and the machine is provided with a curved needle indicated at 6 and a curved awl (not shown) which rock in a vertical plane for the formation of each stitch, the needle and awl passing through openings 8 and ID in the work supporting faces 2 and 4 to penetrate the work. Some half an inch to the right of the right hand edges of the openings 8 and H), the work support is provided with a strip guide 3 for a strip of beading [8 (see Fig, 2) of the kind re ferred to, this guide being arranged to guide the strip to the sewing point of the machine between the two parts of the work being sewn together. The strip guide 3 is a comparatively small metal block arranged to project between the two parts of the work and having passing through it a strip guiding passageS. The strip guiding passage 5 in the strip guide has substantially the shape of a keyhole slot, i. e., the passage has at one end of it a rounded part 1 to guide the beaded edge of the strip and from this circular portion there extends a comparatively narrow part 9 which guides the remainder of the strip.

The slot lies normally substantially parallel to the lower work-supporting face 4 of the work support, which face is normally inclined downwardly and forwardly in the machine, and the end of the block which has in it the'rounded part I is received, beyond the part I of the slot, within an opening I3 in the wall of the work support which provides the work-supporting face 2, this wall normally extending upwardly and forwardly in the machine. The strip guide 3 is pivoted on a pin ll extending parallel to the line of work feed and secured in the said wall so that, for a purpose hereinafter described, the strip guide may be swung upwardly about the pin I! from its normal position in which it lies substantially parallel to the lower face 4 of the work support and slightly above the latter. The wall of the work support providing the face 2 has formed in it beneath the-opening 8 a groove I!) which is parallel to the" lower work supporting face 4 and is positioned in the wall 2 a little above the face 4. The groove l9 and the portion 1 of the slot in the strip guide are substantially coaxial and the groove l9 receives the beaded edge of the strip so that the two parts of the case or bag closely engage the strip and so that the beaded edge of the strip stands out from the corner formed between the parts as indicated in Figure 2. As also indicated in that figure, the presence of the beaded portion of the strip in the groove l9 will, unless the groove is sufliciently deep, prevent close contact between the two parts of the case before they are sewn together, but the parts will be drawn close together and caused to bind tightly against the beaded edge by the tension exerted on the needle and shuttle threads dur-- ing the formation and setting of the stitches. The flange portion of the strip is guided to lie,

. while parts are being sewn together, flat on the upper face of the case or bag part which is pressed being sewn together, the needle 6, which follows a curved path indicated at X in Figure 2, strikes flrst through the part of the work supported by the face 2, then through the flange portion of the strip and finally through the other part of the work thus sewing the strip and the two parts together at a single operation. To enable the strip guide 3. easily to pass between the two parts of the case or bag which are normally urged towards each'other as they are fed along the work support, the face 4 -of the latter has its right hand portion 2| inclined downwardly relatively to the plane of the face 4 so that the portion of the case or bag supported by the face 2| may be bent slightly downwardly away from the edge of the part which is pressed against the face 2 of the work support to allow the guide 3 the more easily. to project between the parts of the case or bag.

If the beginning and end of the seam joining the two parts of a case or bag together are to meet or overlap slightly when the seam is completed, as is the case for instance of a circular collar box in which the bottom is sewn to the side wall, it is necessary, as the first stitches made in the work approach closely to the sewing point once more near the end of the sewing of the seam, to withdraw the strip from the strip guide and to withdraw the strip guide 3 from between the parts of the case orbag to facilitate the completion of the seam, the strip being guided after the withdrawal of the guide by the groove l9 ing part of the work has been drawn forwardly away from over the guide, be satisfactory for sewing some kinds of work in which the ends of the seam are to overlap, a more suitable form of guide for use on this kind of work is illustrated in Figure 4. This guide is arranged to occupy a similar position on the work support to that occupied by the strip guide 3 but instead of consisting of a pivoted metal block, the guide shown in Figure 4 consists of a clip-like member 23 formed of resilient metal and detachably held on the work support. The member L23 presents, near its rear end, a shouldered passage 25 in line with the groove I!) to receive and guide the beaded edge of the strip and, in front of the passage, a narrow passage 21 to receive and guide the flange portion of the strip. The rear end portions of the member 23 are flared apart somewhat but their extreme rear ends are turned towards each other to provide ridges on the member which enter into grooves 29 provided in a cut-away portion of the work support. The resilience of the member 23 urges the said ridges into the grooves 29 and thus serves to retain the member in place on the work support in a similar position, considered both heightwise-and lengthwise of the support, to that occupied by the strip guide 3. At the forward end of the narrow passage 21 the member 23 provides a finger grip, it being extended well forwardly for this purpose, and by pressing the upper and lower portions of the member towards each other the operator may release the ridges on the member sufllciently from the grooves 23 to allow him tq withdraw the member forwardly and detach it from the work support, the strip Ill being left substantially in its correct position undisturbed by the withdrawal of the member for the completion of the seam.v The member 23 thereforev provides a readily detachable strip guide which may either be left permanently in operative position on the work support when work 'is being operated on in which the-ends of the .seam are not to overlap or may be ,quickly and easilyi removed to' allow of the overlapping of the ends of the seam when operating on work in which 'this, is desired.

Thestrip guide 3! shown in Figures 5, 6, and 7 is substantially similar to that shown in Figure 4, but is of a somewhat more robust construction. The strip guide 3| has a hooked end 33 g which may be grasped by the operator when it is desired to withdraw the guide from the work support 35 or to place it in position thereon. The guide 3| has a portion 31 which is held in an opening 39 in the work support 35 by a wire sprin ll secured by a screw 43 to a block 45 and engaging a groove 41 extending across the portion 31. The block 65 is secured in a recess 49 in a wall 5| of the work support and the lower face of the block forms the upper face of the 'opening 39. The bottom and side faces of the opening 39 are formed by a comparatively small recess in the wall 5| at the bottom of the recess 49. The strip guide 3! has formed in it a pasisage 53 for guiding the flange of a beaded strip and also has formed in it a rounded recess 55 which, in conjunction with a rounded recess 57 in the Wall 5|, forms a guide for the beaded edge of the strip. The work support 35 is substantial- =ly similar to the work support I, having a groove "59 similar to the groove l9 and a downwardly inclined portion 6| similar to the downwardly inclined portion 2i and for the same purposes. The strip as it'passes through the guide 3|, however, lies parallel to the face 6 in Figure 1. This arrangement of the strip guide 3! enables the strip guiding portion of the guide to lie comparatively close to the inclined portion and in a position such as to allow the lower edge of the part of the case or bag which is held against the, face 59 of the work support to pass over the guide. The strip guide 3| may be readily withdrawn when desired from between the two parts of a case or bag which are being sewn together by merely drawing it forwardly.
