UNITED STATES EMANUEL ESOHELBAOHER, OF NEW YORK, N. Y.

SEWING-MACHINE ATTACHMENT.

Specification of Letters Patent.

Patented Oct. 1, 1907.

1 Application filed April 29, 1907- Serial No. 370,963.

To all whom it may concern:

Be it known that I, EMANUEL ESCHELBACHER, a citizen of the United States, residing in the city of New York, county and State of New York, have invented certain new and useful Improvements in Sewing-Machine Attachments, of which the following is a full, clear, and exact specification.

This invention relates to sewing machine attachments.

The object of the invention is to provide a strong, simple, durable, inexpensive and thoroughly efficient attachment adapted to produce either single or double plaits or tucks.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of the following claims without departing from the spirit of the invention.

In the accompanying drawing forming part of this specification, Figure 1 is a front elevation of a plaiting attachment constructed in accordance with the invention, a portion of the device being broken away. Fig. 2 isa section on the line 2-2 of Fig. 1, with the needle bar and presser-foot removed. Fig. 3 is a side elevation of the construction shown in Fig. 1. Fig. 4 is a plan view of the presser-foot. Fig. 5 is a plan view showing a slightly modified arrangement of plate and guide member. Fig. 6, is an end elevation of the construction shown in Fig. 5. Fig. 7, is a cross section through a piece of fabric formed with a double plait by means of the attachment of the present invention. Fig. 8, is a detail view of the plate and guide members shown in Fig. 1.

Like reference numerals indicate corresponding parts in the different figures of the drawing.

Referring to Fig. 1 of the drawings the reference numeral 1, indicates a plate which is suitably mounted in the sewing-machine-table above the bobbin-carriers. The plate 1, is preferably thickened as shown in Fig. 8, so that it will extend at its upper end above the upper surface of the sewing-machine-table which is indicated by the horizontal line extending across the lower end of Fig. 1. The plate 1 in the side edges thereof above the sewing-machine-table is formed with a pair of grooves 3, which are approximately U-shape in cross section and serve to produce an upper guide member 4 and a lower guide member 5. As shown in the draw ing, the pairs of upper and lower guide members 4 and 5 project in opposite directions. Extending into the space between each pair of upper and lower guide members 4 and 5 is a tongue 6, which, as shown particularly in Fig. 2, preferably is of approximately semicrescent shape. The pointed forward ends 7 of the two tongues 6 preferably extend outwardly in advance of the plate 1. As shown in Figs. 1 and 2, the two tongues 6 project in opposite directions, and the tongues and 'guide members 4 and 5 overlap each other as shown, so

that whena piece of fabric is fed in the usual direction, it passes under the two tongues 6, around through the grooves 3 and over the top of the plate 1, so as to produce double plaits as shown clearly in Fig. 7. The resser-foot and double needles hereinafter described, operate on the fabric in rear of the plate 1 and tongues 6 so as to stitch the plaits as they leave the grooves 3 of the plate 1. i

For the purpose of permitting the tongues 6 to be adjusted a greater or lesser distance into the grooves 3, so as to regulate the width of the plaits, each of the tongues 6 is bent upward at an intermedinte portion thereof as indicated at 10, and is provided with an extension 11 in which is formed a longitudinal slot as indicated at 12 in Fig. 2. The slotted extension 11 of each tongue 6 rests upon the horizontal portion 14 of what I shall-term a bracket A and is adjustably secured thereto by means such as the screws 15. By loosening the screws 15, the tongue 6 can be adjusted toward or from the plate 1. Integrally connected with the one edge of the horizontal portion 14 of each bracket A is a vertical extension 16 which is formed with a longitudinal slot 17, and is adjustably connected with an angular member 18 by means such as the screws 19. By loosening the screws 19, each bracket can be vertically adjusted upon the member 18 so as to cause the tongue 6 to project accurately into the center of the grooves 3 in the plate 1. Each of the angular members 18 is pivotally connected as indicated at 20 with a support 21, which, in the embodiment of the invention illustrated, consists of a portion of the ordinary sewing machine. When the two pivotal members 18 are raised as indicated by the dotted lines in Fig. 1, the fabric to be plaited or tucked can be placed over the plate 1, after which when the pivotal members 18 are moved down into the fullline position shown in Fig. 1, the plaits will be formed as previously described. For the purpose of limiting the downward movement of the two pivotal members 18, limiting pins 22, are screwed into the support 21 as shown in Figs. 1 and 3. In order to permit the parts of the attachment to be locked in the positions shown in Fig. 1, locking devices such as 25 are employed. Each of the locking devices 25 preferably is formed with an integral vertically extending ear 26 which is pivotally'mounted at 27 upon the piv otal member 18. Each of the locking devices 25 is also provided with an upwardly bent end 28 which is adapted to fit into a suitable groove or socket 29 formed in the support 21. A spring such as 30 is employed for holding each locking device in operative position. When the end of the locking device is pressed upwardly, the pivotal member 18 together with the tongues 6, can

be raised. The upward movement of the pivotal mem ber 18 is limited by the bent end 28 of the locking device engaging a shoulder 32 upon the support 21.

The presser-foot is indicated by the reference numeral 35 in Figs. 1 and 3, and is adjustably connected by means of screw 36 with a rod 37 which depends upon the support or head 21. The reference numeral 10 indicates the needle bar which is provided at its lower end with a head 41 carrying a pair of needles 42 which work through perforations 43 formed in the prcsser-foot 35 as shown in Fig. 4 in the usual manner.

In the modified construction illustrated in Figs. 5 and 6, the upper and lower guide members l and 5 which form between them, the grooves 3 are adjustably mounted upon the plate 1. These guide members 4 and 5 are provided with overlapping extensions 50, each of which extensions is iormed with a pair oi slots 51 through which extend screws 52 connected with the plate 1 By loosening the screws 52, the extensions may be adjusted away from each other so as to increase the distance between the two plaits 55 shown in Fig. 7. The arrangement 01' the other parts of the attachment including the tongues 6, is the same in Figs. 5 and 6 as that shown in Fig. 1.

It will be understood that it it be desired to produce only a single plait, instead of double plaits shown in Fig. 7, one of the tongues 6 will be removed or left out of operation.

The plaiting attachment of the present invention is strong, simple, durable and inexpensive in construction as well as thoroughly el'licient in operation.

What is claimed is:

1. A plaiting attachment including a support of a pair of oppositely extending pivotal members on said support,

a bracket adjustably connected with each pivotal member, a tongue adjustablv connected with each bracket, the two tongues extending in opposite directions, and a plate having a pair 01' oppositely extending guide members overlapping said tongue.

2. A plaiting attachment comprising upper and lower guide members, a tongue extending into the space between said guide members, said tongue being bent upward intermediate its ends and having a slotted extension, a bracket having a horizontal portion adjustably connected with said slotted extension of the tongue, said bracket: having a vertical slotted extension, and a pivotally mounted member adjustably connected with the slotted vertical extension of said bracket.

23. A plaiting attachment comprising upper and lower guide members, a. tongue projecting into the space between said upper and lower guide members, a bracket. :nljustablv connected with said tongue. and a pivotall mounted member adjustably connected with said bracket.

-l-. A plaiting attachment comprising upper and lower guide members, a tongue extending into the space between said guide members, a bracket. adjustably connected with said tongue, at pivotally mounted member on the sewing machine head adjustably connected with said bracket and a locking device on said pivotally mounted member for locking the tongue in place.
