TAPE-GUIDE FOR SEWING-MACHINES.

Specification of Letters Patent.

Patented Aug. 22, 1916.

' Application filed September 18, 1912. Serial No. 721,048.

To all whom it may concern:

Be it known that I, JOSEPH BERGER, J r., a citizen of the United States, residing at 40 Genesee street, Utica, in the county of Oneida, State of New York, have invented certain new and useful Improvements in Tape-Guides for Sewing-Machines, of which the following is a description, reference being had to the accompanying drawing and to the figures of reference marked thereon.

The invention relates to new and useful improvements in tape guides for sewing machines.

An object of the invention is to provide a tape guide which is so supported that it may be readily moved away from the stitch ing mechanism to facilitate the cutting of the tape, and which is further so constructed that it may be moved for feeding or placing the cut end of the tape underneath the presser foot, whereby said tape will be engaged and moved forward by the feeding mechanism without requiring any hand manipulation of the tape.

A further object of the invention is to provide a tape guide and support therefor with means for moving the tape guide to feed or place the tape underneath the presser foot, which means is actuated from a treadle or knee shift, so that the operators hands may be free to shift or manipulate the material being stitched.

A further object of the invention is to provide a tape guide and supporting mechanism of the above character which is so constructed that the tape guide will be automatically moved upon the raising of the presser foot to its extreme upper limit, so that the free end or cut end of the tape may be inserted or placed underneath the presser foot.

These and other objects will in part be obvious, and will in part be hereinafter more fully described. V

In the drawings, which show by way of illustration one embodiment .of the invention. Figure 1 is a rear view of. a sewing machine, having my improvement applied thereto; Fig. 2 is an enlarged perspective view showing a portion of the sewing head and my improved tape guide attached thereto; Fig. 3 is a view similar to Fig. 2,

- showing thetape guide raised to permit the cutting of the tape; Fig. 4 is a detail partly in section and partly in end view showing the support for the tape guide and its attachment to head of the machine. Fig. 5 is a detail in plan showing one of the purpospls for which my improved guide may be use 1 In the drawings I have shown my improved tape guide as applied to a sewing machine consisting of a work support 1, an overhanging arm 2, a needle bar 3, carrying spaced needles 4. Cooperating with the needles beneath the work support may be any suitable complemental stitch forming mechanism. The needle bar is reciprocated in the overhanging arm by the usual needle lever, which is operated from the main shaft 5 by an eccentric strap or link 6. Also mounted in the overhanging arm is a presser bar 7 carrying a presser foot 8, at its lower end. This presser bar 7 is provided with a collar 9, which carries a pin 10, and the leaf spring 11, resting on the pin normally holds the presser bar in yielding engagement with the work support. The presser foot is raised by a lever 12,-which is pivoted at 13 to the'overhanging arm. The rear end of the lever 12 is provided with a chain or other flexible member 14:, which is connected to a treadle or knee shift. This lever 12 is held depressed at its forward end by a spring 15. Upon depressing the treadle or moving the knee shift laterally, the lever 12 will be oscillated about its pivotal support and the free end of the lever will engage the pin 10'and raise the presser foot from the work support.

Mounted to reciprocate vertically in lugs carried by the overhanging arm is a guide bar 16. This guide bar is provided with a collar 17 and with a laterally projecting arm or pin 18 which extends through the presser bar 7. This guide bar 16 will, therefore, be raised and lowered-with the presser bar, and will prevent the presser bar from rotating in its bearings. Atthe lower end of the guide bar 16 is a laterally projecting block or bracket 19. Pivoted to this bracket 19 is an arm 20, a pin or screw 21 extends through the arm into the bracket 19 and serves as apivotal support for the arm. A flexible washer or tension plate 22 is carried by the pivot pin 21, and bears against the arm 20, so that said arm will be frictionally held against the supporting bracketyg along the stop and thus force the arm 19 therefor. This arm 20 projects forwardly and is bent laterally in front of the needle 1 movement of the arm 20 carries the tape bar, and the tape guide 23 is carried thereby. This tape guide, as herein shown, is rectangular in cross section, thus forming a front wall at and a rear'wall 25. A spring 26 is attached to the head of the tape guide bya screw 27. This spring projects up wardly and is curved so as to extend downwardly through the tape guide. The purpose of the spring is to put a slight tension on the tape, which may be changed by turning the screw 27. The sprlng 26 rests on the inner end of the screw 27, so that by turning thescrew 27 the spring may be forced toward the inner wall 24: of the tape guide. This causes the spring to press against the tape and put a tension thereon, so as to prevent the tape from being drawn back through the tape guide.

A pin 28 carried by the arm 20 engages i the bracket 19 and limits the downward movement of the arm 20. When the arm 20 is lowered so that the pin engages the bracket, the tape guide is so proportioned that the delivering end is below the upper face of the presser foot and adjacent the under surface of said presser foot, The presser foot 8, as shown in the drawings, 1s cut away, as at 29, to make room for the tape guide.

Mounted on the head of the mach ne 1s an adjustable stop 30. This stop is 1n the form of a laterally projecting lug, having a tapering face 31 on its lower edge. The arm 20 is formed with a V-shaped notch, which provides two

inclined walls

32 and 33. In the operation of my device the tape guide is positioned as shown in Flg, 2, and the tape T passing through the guide will be laid underneath the presser foot so that the edges of the tape will be stitched to the body material by the needles 4.4. WVhen it is desired to end the tape on a garment, the arm 20 is swung about its pivotal point and the stop 30 will engage the wall 32 on said arm 20 and limit the upward movement of the tape guide. In Fig. 3 of the drawings I have shown the tape guide swung to this position, and in dotted line I have shown the manner of the severing of the tape. By this moving of the tape guide away from the stitching mechanism, the tape may be severed so that the end thereof can be folded underneath for finishing 05 the tape. When the parts are in this position, shown in Fig. 3, the lower edge of the stop 30 is some distance above the wall 33, so that the presser foot may be raised sufficiently for removing the material, if desired, before the stop contacts with the wall 33. A further lifting of the presser foot, which carries with it the bracket supporting the tape guide, will cause the inclined wall 33 to slide .120 to its lower position where the stop 28 engages the bracket 19. This downward guide to its normal position relative to the presser foot, and the free or cut end of the tape projectingbeyond the end of the tape guide will be inserted or placed underneath the presser foot so that when the presser foot is lowered, and the machine started, the tape will be automatically engaged by the said feed and carried to the stitching mechanism without requiring any band manipulations of the tape. Inasmuch as the presser foot is raised and lowered by the treadle or knee shift connection, it will be apparent that the r example in Fig. 5. The'inserted material 3st is stitched to the body garment 35 and a tape 36 applied, so as to cover the cut edge of the inserted part 34. When the turning point is reached, thepresser foot may be raised without disturbing the relative position of the tape guide so that the goods may be readily manipulated for stitching the opposite side of the insertion. \Vhen the end of the seam is reached, the tape guide may be raised and the tape severed, as above noted, so that the end of the tape may be folded underneath for stitching.

l/Vhile my improved device is especially adapted for this particular class of work, it

is also equally adapted for other types of work, such as stitching labels on garments, where the label is printed on a strip of tape, and for any other class of work where the tape'or a strip of fabric is stitched to a garment.

While I have referred to my device as gulding a tape, it is to be understood that I do not limit myself to the guiding of a strip having a selvage edge, but said device may be equally used for guiding a cut strip of fabric.

It is obvious that minor changes in the details of construction and the arrangement of parts may be made without departing from the spirit of the invention as set forth in the appended claims.
