Specification of Letters Patent.

Patented May 11, 1915.

Application filed December 10, 1908. Serial No. 466,861.

To all whom it may concern Be it known that I, LANSING ONDERDONK, a citizen of the United States, residing at New York city, in the county of New York, State of New York, have invented certain new and useful Improvements in Tucking- Guides for Sewing-Machines, (Case A,) of which the following is a description, reference being had to the accompanying drawing and to the letters and figures of refer-- ence marked thereon.

My invention relates to new and useful improvements in tucking guides for sewing machines, and has for an object to provide a tucking guide, whereby a plurality of tucks may be formed, certain of said tucks being formed after the others, and all of said tucks simultaneously stitched.

A further object of the invention is to provide a tucking guide for forming a plurality of tucks, which is so constructed that on the initial insertion of the fabric, a certain number of the tucks may be first formed in the fabric and then the remaining tucks subsequently formed in the fabric.

A further object of the invention is to provide a presser foot which is constructed for cooperation with my improved tucking guide, so as to aid in folding down and holding the tucks which have been formed, until they are stitched.

These and other objects of my invention,

will in part be obvious, and will in part be" hereinafter more fully described.

In the drawings which show by way of illustration one embodiment of the invention; Figure 1 is a front view of the forward end of a sewing machine, with my improved tucking guide attached thereto. Fig. 2 is a top plan View thereof. Fig. 3 is a plan view of the lower folding plate. Flg. l is a sectional view through the upper supporting member, and showing the relative position of the tuck forming plates. Flg. 5 is a detail view showing the upper tuck forming member in its raised position. Fig. 6 is a front view of the forward end of the machine, showing a modification of the invention, in that the upper tuck forming member is supported by the head of the machine. Fig. 7 is an end view of the machine showing the modified form of the invention, certain parts being in section. Fig. 8 is a top plan view of the same. Fig. 9 1s abottom view of my improved presser foot. Fig.

1( is a front View thereof. Fig. 11 is a side View of the presser foot. Fig. 12 shows a modified brake holding means.

My invention as herein illustrated, is shown as applied to a multiple needle sewing machine, which comprises a work support 1, an overhanging arm 2, in which reclprocates a needle bar 3, carrying a plurality of needles 4. The stitch forming mechanism may be of any desired construction, and will not need further description.

My improved tucking guide in the present embodiment of my invention, includes a lower tuck folding member 5, which is secured to the work support by suitable screws 6, 6, which pass through the openings 7, 7, in the base plate 8 of the lower member 5. Said openings 7, 7 may be of sufiicient size so that said base plate may be adjusted relative to the work support and the stitch forming mechanism. Said base plate 8, carries a plurality of folding guides 9. Each of the folding guides 9, is formed with an upright portion, which is bent laterally so as to fold over the fabric to form the tuck. The folding guides 9, are herein shown as formed integral with the base plate 8. It is evident however, that said folding guides, from certain aspects of the invention, may be of different shapes, and also may be secured to the base plate in any desired manner. As viewed in Fig. 3, the tucking guide 9, at the extreme right, is shorter than the tucking guide adjacent thereto. As a matter of fact, each of the tucking guides from the right to the left, is shown a little longer than the tucking guide adjacent thereto. The purpose of making the tucking guides one a little longer than the other, is so that the longest tucking guide will form its tuck in the fabric, before the fabric reaches the guide adjacent thereto, and this guide adjacent thereto, will form its tuck before the fabrio reaches the third tuck forming guide. That is to say, the first tuck forming guide draws the fabric laterally until sufiicient slack is secured for forming the first tuck, then the second tuck forming guide draws the fabric laterally, until its tuck is formed, and so on, forming one tuck after another. It will be readily seen that if the tuck forming guides were all of the same length, then all of the tucks would be formed at one time, and there must necessarily be a slipping of the fabric laterally over the tuck forming guides. By my improved tucking guide however, this lateral slipping of the fabric over the tucking guide, is avoided, and I am thereby enabled to form a plurality of tucks without unduly stretching the fabric.

Cooperating with the lower tuck form ing member is an uppertuck forming member 10, which as herein shown, includes a supporting bracket 11, pivoted at 12 to the depending flange of the work support, and extending up through a slot 13 in the work support. The supporting bracket 11, carries a projecting arm 14, adjustably supporting an arm 14 which carries a plurality of tuck forming fingers 15. Said supporting arm 14 also carries a smoothing plate 16. A second arm 17 is pivoted at 18 to the smoothing plate 16, and is arranged in line with the arm 14 The arm 17 also carries a plurality of tuck forming fingers 19. The tuck forming fingers 15 and 19 are similarly shaped and as herein shown are formed with a downwardly extending shank and a laterally inclined portion, which is substantially parallel with the inclined portion of the tuck forming guides, and said tuck forming fingers are arranged so as to lie between the respective tuck forming guides, as clearly shown in Figs. 1 and 4. The tuck forming fingers 15 and 19 vary in length to correspond with the length of the tuck forming guides as clearly shown in Fig. 2.

The upper tuck forming member is held on the fabric by a latch 20, which is adjust-- ably secured to the depending flange of the work support by a screw 21. An adjustable screw 22, engages the end of the arm of the bracket 11. A spring washer 23 surrounds the pivot 12 and serves to hold the arm 14 in its various positions. During the operation of the machine, the upper member of the tucking guide is held on the fabric in a position shown in Figs. 1, 2 and 4. The latch 20 is released and the arm 14 raised so that the fabric may be placed on top of the tuck forming guides. The arm 17 is allowed to swing freely about its pivot point 18, and the arm 14 is lowered so that the tucking fingers 15 will crowd the material down between the tuck forming guides, thus forming tucks in the material. In the formation of these tucks, there is of course, necessarily a lateral slipping of the fabric over the tuck forming guides, until sufiicient slack is obtained in the fabric to form the tuck. After the series of tucks have been formed by the tuck forming fingers 15, then the arm 17 is crowded down so that the tuck forming fingers 19 will crowd the fabric down between the tuck forming guides, with which they coiiperate, and thus the remaining tucks are formed. After the arm 17 has been swung down to its proper place, the slide 24, which is secured to the arm 17, by means of a screw 25, passing through a slot 26 in the slide, is moved laterally until its notched end engages a headed stud 27 carried by the arm 14". This locks the arm 17 in its lowered positio'n.

The forward end of the arm 14 is beveled as at 28 and the beveled end 29 of the arm 17 engages the same, which limits the downward movement of the arm 17. It will thus be seen by my improved tucking device, that when the fabric is inserted in the tucking guide, a certain number of tucks are first formed in the fabric and then the remaining number of tucks are formed. This manner of inserting the fabric in the tucking guide, avoids the strain which would necessarily be placed on the fabric, if a great number of tucks were simultaneously formed by the crowding down of the upper tuck forming member into the lower tuck forming member. It will also be seen that during the operation of the machine, first one tuck is formed, and then another, and so on, thus again, avoiding all unnecessary strain upon the fabric. The smoothing plate 16 holds the fabric down on the base plate 8' of the lower tuck forming member, and thus aids in the feeding of the material to the tucking guides and in the proper formation of the tucks. After the fabric leaves the tucking guides, the tucks are fed underneath the presser foot and are simultaneously stitched by the stitching mechanism.

In the modification of my invention, shown in Figs. 6, 7 and 8, I have shown the upper tuck forming member as carried by the head of the machine. This construction gives a wider range of operation of my tucking guides, as the width of the fabric being tucked is then only limited by the capacity of the sewing machine. In carrying out this part of my invention, I have provided the overhanging arm with a laterally extending bracket 30 which is carried by a split collar 31, secured to a boss on the lower end of the overhanging arm by means of a screw 32. provided with a projecting stud 33. A collar 34 is carried by said stud 33. Said collar 34 is provided with a downwardly and laterally projecting arm 35, which carries the smoothing plate 16. The smoothing plate 16 is provided with an adjustable arm 36, which carries a plurality of tuck forming fingers 37. The collar 34 is held on the stud 33, by a large headed screw 38. Mounted on the collar 34, is a second collar 39, which has a downwardly extending arm 40, carrying in turn, a second arm 41, which is provided with a plurality of tuck folding fingers 42. The arm 36 is secured to the arm 41 by a slide 43 which is similar in The bracket 30 is Y construction to the slide 24. The collar 34 is also provided. with an upwardly extending arm 44, which carries an adjustable stop screw 45, adapted to contact with a bar 46, and limit the downward movement of the smoothing plate and the tuck folding fingers carried thereby. A spring latch 47 engages the arm 44, and'holds the same against the bar 46. The collar 39 is provided with a similar arm 48 carrying an adjustable stop screw 49 and said arm is held so that the tuck forming fingers are in their lowered position by means of a spring latch 50.

The operation of my tucking guide as illustrated in Figs. 6, 7, and 8, is similar to that above described. The tuck forming fingers and also the tuck forming guides, are shown with the shortest tuck forming guide on the left, instead of on the right, as shown in Fig. 4. The operation however, of forming the tucks is precisely the same. Cotiperating with the tuck forming guides is a presser foot 51, which is provided with a plurality of needle slo s 52. The forward end of the presser foot 51 is turned up as shown in Fig. 11. The end face of the presser foot is provided with a plurality of notches 53, each of which has a straight side 54 (Fig. 10), and an inclined side 55. The purpose of the inclined side 55 of the tuck receiving notch is toturn down the tuck fiat upon the fabric, while the straight side 54 guides the edge of the tuck. The guiding notches in the presser foot receive the tucks as they leave the tuck forming guides and serve to hold the tucks in proper position and direct the same to the-needles of the stitch forming mechanism.

While I have shown in Fig. 2 the ends of the tuck folding members adjacent the forward end of the machine as in a line at an angle to the path of movement of the fabric to the tucking guide, it will be obvious that one or two of the tucking guides may have their ends arranged in a line at right angles to the path of movement of the fabric, through the tucking guide, as shown for example, in Fig. 8. In this instance, two of the tucks would be simultaneously folded, while the remaining tucks would be formed one after another.

It will be obvious that the ends of the tucking guides may be arranged in pairs as above noted. It will also be obvious that the center guide may be the longest guide, and the guides on each side thereof, successively shorter. The main purpose of the invention is to fold at least some of the tucks where a great number of tucks are being made, after other of the tucks, so as to avoid the strain incident to the simultaneous folding of a great many tucks.

In the construction shown in my modified form of the invention, the ends of the arms supporting the tuck folding fingers are formed in the arc of a circle, the center of which is the pivotal axis of the supporting arm. It will thus be seen that either of the sets of tuck folding fingers may be lifted from the fabric or lowered on to the fabric independently of the others. The lower position of the tuck folding fingers is determined by the adjustable stop screws.

The arm 14 may be readily adjusted on the arm 14, and by loosening the screws 6, the plate 5, carrying the formers 9, may be adjusted. By these adjustments, it will readily be seen that the size of the tucks and also the spacing of the, tucks may within certain limits, be varied.

By adjusting the arm 36 (Fig. 8), the po sition of the tuck forming fingers 37 relative to the formers on the base plate'may be set so as to differ from the position of the tuck forming fingers 37, relative to the formers on the base plate. By this adjustment it will be seen that I can make at one time, two clusters of tucks which are of different sizes or differently spaced. If clesired, the auxiliary tuck forming fingers 42, as shown in Fig. 8, or the tuck forming fingers 19, as shown in Fig. 2, may be rendered inoperative, and the tuck forming fingers 37' or 15 will operate to form a cluster of tucks. By throwing these auxiliary tuck forming fingers into and out of operation, I may if desired, make first a cluster of tucks having a certain number, and then another cluster of tucks having a different number. By the above adjustments, tucks close together or wideapart could be made as desired, without changing the position of the guiding fingers and formers relative to each other, except to throw the auxiliary tuck forming fingers into or out of operative position.

In Fig. 12, I have shown a. different form of mechanism for holding the bracket arm 11 with the tuck formers in operative position. In this figure, the bracket arm 11 is pivoted at 12 to the work support 1. Two links 60 and 61 are pivoted to each other at 62. The link 60 is pivoted at 63 to a suitable screw connected to the bracket arm 11. link 61 is pivoted at 64 to a bracket 65, which is rigidly but adjustab ly, secured to the work support 1. The bracket 65 is connected to the work support by a pivot screw 66 and a slot and screw connection 67, which serves as means for adjusting the brackets 65 on its pivot. The link 61 is provided with a stop 68, which serves to limit the further movement of the toggle links when the The the toggle is broken in the well known manner and the bracket arm 11 may be swung about its pivot 12. The location of the formers when in operative position, may be adjusted by adjusting the position of the bracket 65.
