Application filed February 9, 1917. Serial No. 147,593.

To all whom it may concern."

Be it Vknown that I, JOSEPH Il. STENGEL, a citizen of the -United States, residing at Cincinnati, in the county of Hamilton, State of Ohio, have invented certain new and useful Improvements in TapeGuides for Sewingdl/Iachines, 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, and more vparticularly to a tape guide which may be readily adjusted to guide tapes of different widths.

In certain classes of work, it is desirable to stitch simultaneously a plurality of tapes to a fabric, and these tapes are stitched on av multiple needle stitching machine. An object of the present invention is, therefore, to provide a tape guide for a multiple needle machine, which tape guide is capable of simultaneously guiding tapes and directing the same to the respective needles, and wherein said tape guide may be quickly adjusted so that all tape guiding sections may be simultaneously varied to the same extent-for a series of tapes of a different width.

A further object of the invention is to provide a tape guide for sewing machines, which tape guide includes a cylindrical member having a circumferential groove of varying width, together with means whereby a section of said groove is made operative for guiding a tape to the stitching mechanism, and wherein the cylindrical member may be adjusted about its axis to vary the width of the portion presented for guiding the tape. Y

These and other objects will in part be obvious and will in part be hereinafter more fully disclosed.

In the drawings, which show by way of illustration one embodiment of the invention Figure l is a front view of a portion of a sewing machine having my improved tape guide applied thereto;

Fig. 2 is an end view of the same;

Fig. 3 is a view, partly in section and partly in plan, showing a part of the work support and presser foot having my improved tape guide;

Fig. 4 is a vertical sectional View on the line 4--4 of Fig. 3;

Fig. 5 is a bottom plan view of the .presser foot with the tape guide carried'thereby;

Fig. 6 is a sectional viewthrough the presser foot centrally of the tape guiding member, showing the tape guiding member for guiding a series of tapes of a given width.

Fig. 7 is a similar view, but showing the tape guiding member adjusted for guiding a series of tapes of a different width;

Fig. 8 is a sectional view on the line 8-8 of Fig. 6, the tape and fabric being omitted; and

Fig. 9 is a perspective view of the tape guiding member.

In carrying out the invention, I have provided a tape guiding member which is pref erably cylindrical in form and which is provided with a series of circumferential grooves which extend into the surface of the cylindrical member sul'liciently to form tape guiding walls. Each of these circumferential grooves is constructed so that it varies in width, this variation being preferably uniform. The cylindrical member is mounted in the presser foot of the sewing machine in advance of the needles, and the presser foot is provided with means for directing a tape so that a section of the groove becomes effective for guiding the tape which is being stitched. The directing means on the presser foot is of sufficient capacity to take a tape of the Widest width that can be guided by the cylindrical tape guiding member so that this cylindrical member becomes the active means for guiding the series of tapes to the respective needles. It is often desirable to stitch a series of tapes of a different vvidth. This may be readily accomplished by adjusting this cylindrical member so as to present a tape guiding surface which is of proper width to guide the series of tapes which it is desired to stitch to the fabric. The cylindrical member is for this purpose adjustable about its axis, and means is provided for holding it in an adjusted position. Y

Referring more in detail to the drawings I have shown my invention applied to a sewing machine which is formed with a work support l, an overhanging arm 2 carrying a needle bar 3, in which is mounted a series of needles 5. As herein shown, there are ve needles. Cooperating with each neey dle beneath the Work support is a looper Eachneedle and coperating looper is entirely independent of the other needles and theircoperating loopcrs. Y

The material is fed across the wor-k support by a feed dog 7 which may be of the usual construction. The material is held on the Work support by a presser foot 8 carried 'by ay presser bar 9 mounted in the overhanging arm 2 in the usual manner. The presser foot is provided with a series of needle openings 10, one foreach needle. The presser foot is also formed with a slot 11 which extends across the presser foot and Which is located directly in front of the nee dle openings 10.

Mounted in the slot 11 is a cylindrical tape guiding member 12. The presser foot is formed With a raised portion 13 at one side thereof, and a supporting pivot screw 14 extends through this raised portion and is threaded centrally into the cylindrical member 12, as clearly shown in Figs. 6 and 7 of the drawings. The other end of the cylindrical member extends into a socket 15 formed 'in the raised portion 16 of the presser foot. A set-screw 17 carried by this raised portion 16 is adapted to clamp the cylindrical portion and hold it in an adjusted position. Saidcylindrical portion 12 is formed with a slot 18 for a screw-driver to facilitate the adjustment of the same.

This cylindrical member 12 is formed With circumferential grooves 19. There are five grooves, one for each tape. These grooves are of similar construction, and only one groove will, therefore, be described 1n de tail. The groove extends into the cylindri- .cal member so as to form side Walls 20 and 21. The groove varies in Width. Extending longitudinally of the member 12 is a groove 22, and the groove 19 extends into f this longitudinal groove 22. The maximum v and minimum Widths referred to.

Width of the groove 19 is at one side of the groove 22, While the minimum Width is at the other side thereof, and the groove varies uniformly in Width between the maximum The presser foot carries a plate 23, Which extends from end to end thereof in front of the cylindrical member 12, and this plate is formed with spaced guiding yrecesses 24, one for each groove 19, and the Width of each recess 24 is the maximum Width of the groove With Which it cooperates.

In Fig. 3 of the drawings, I have shown a series of tapes, indicated at T. Each tape is directed through a recess 24, and then which is substantially on the under face of the cylindrical member 12. The member 12 is turned until the section of the groove presented for guidingl the tape is of the Width of the tape, and the tapes led in through the recesses 2.4 will be properly directed by the grooves 19 so that the needles Will form a line of stitching centrally through the respective tapes.

, Vhen it is desired to change to a series of tapes of different widths, the member 12 is turned until the section of the groove is brought into tape guiding position which is of the Width of the tape desired to be stitched. It will be noted that all the grooves Will be simultaneously adjusted so that the operator may go quickly from a series of tapes of one size to a series of tapes of a different size. It will also be noted that the tape guide is mounted on the presser foot and is raised and lowered therewith, which greatly facilitates the insertion of the material miderneath the same and the removal of the material after the tapes are stitched thereto.

It is obvious that minor changes in the departs may be made, when desired, Without departing from the spirit of this invention, as set forth in the appended claims.

Having thus described the invention, what is claimed as new is 1. The combination with a multiple needle stitching mechanism, of a series of tape guides for independently guiding tapes to the stitching mechanism, and means for simultaneously varying the capacity of the several tape guides.

2. The combination of a multiple needle stitching mechanism, a presser foot, a series of tape guides mounted on the presser foot for independently guiding tapes to the stitching mechanism, and means for simultaneously varying the capacity of the several tape guides.

3. The combination With a multiple stitching mechanism, of a presser foot having tape guiding recesses, a series of tape guides for receiving the tape from said recesses and for directing the same to the needles of the stitching mechanism, and means for simultaneously varying the capacity of the several tape guides.

4. The combination with a multiple stitching mechanism, of a presser foot having a series of tape guiding recesses, a cylindrical member having a series of circumferential grooves adapted to receive the tapes from said recesses respectively and for guiding the tapes to the needles of the stitching mechanism, said grooves being of varying Width, and means for adjusting the cylindrical member for presenting different tape guiding sections of the groove into operative relation with said guiding recesses.

5. A tape guide comprising a cylindrical guiding member having a tape guiding groove extending circumferentially about the same, said groove being of varying Width, means coperating with said member whereby a portion of said groove may be utilized for guiding a tape, means for sup- "porting said member, and means whereby said member may be turned aboutits center axis for varying the Width of the portion presented for guiding the tape.

6. A tape guide comprising a cylindrical guiding member having a series of spaced tape guiding grooves extending circumferentiaily about the same, each of said Grooves being of similar construction and o? varying Width, means cooperating With said member whereby the same corresponding portion of each groove may be utilized to guide tapes of the same Width, means for supporting said member, and means Whereby said member may be turned about a central axis for adjusting the same to receive a series of tapes of diii'erent width.

In testimony whereof, I aflix my signature,

in the presence of two Witnesses.
