The invention relates to new and useful improvements in fabric guide supports for sewand more particularly to a fa ric guide support which is so constructed that the fabric guide may be moved away from the stitching point to inactive posit on in order to give access to the complemental stitch forming mechanism beneath the work ort.

A ix object of the invention is to provide a support for a fabric guide which is so constructed that when the fabric gfiiiide is moved laterally away from the stitc ng pomt, it is also simultaneously raised from the work support. 0

-A further object of the invention 15 to provide a fabric guide support of the above type with a yielding latching means for holding said gulde in normal or operative position. A still further object of the invention is to provide a fabric gulde support of the above type whereinthe fabric guide is so mounted on its support that it may be raised and lowered or adjusted bodily toward and from the stitching-line for properly setting the 'de relatively to the needle of the stitchmg mechanism.

A still further so mounted on the work support that it may be bodily adjusted toward and from the rear edge of the machine.

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

In the drawing;- Figure 1 is a cut view of a sewing machine having the improvements applied thereto;

Fig. 2 is a showing the fabric fabric guide in top p an guide m normal position relative to the needle;

Fi 3 is a view similar to Fig. 2, but showing t e'fabric guide as moved away from the needle;

mounted that object of the invention is to provide a fabric guide support of the aboveview, and with the Fi 5 is a sectional view showing a modiview of the parts be stitched to the stitching mechanism. There has been shown in the drawings, a fabric guide of a bindin strip passes through the guide, and this bin ing stripis inverted and properly positioned relatively to the body fabric for being stitched thereto.- This binding guide shown in the drawings, is mounted on a support pivoted to the cloth plate, so that the abric guide may be moved laterally away from the stitching point to give access to the The support for the guide is so when it is moved laterally, it gradually raises away from the work support. Several different forms are shown for the English binder type wherein accomplishing this result. One consists of a supporting bracket having1 the upper face thereof inclined, so that w en the support for the fabric guide slides along the inclined support, it will be gradually lifted away from the cloth plate. Another form of the invention consists in'the provision of a spiral groove in the supporting stud, and the utilizing of a pin carried by the support for the fabric guide for causing the fabric guide to be lifted as the pin travels along the spiral groove. The fabric guide is held in normal position close to the needle by a yielding latch. The guide properis mounted on its support in such a way that it may be adjusted vertically relative to the support, or

lengthwise of itself relatively to the support and the support for the guide is so mounted on the work support, that it may be adjusted toward and from the rear of the machine.

Referring more in detail to the drawings, a

sewing machine 12 is shown which is provided with a work support a. Mounted on the work support is a fabric guide a, which, as above noted, may be of any desired construction.

" tached to the holder 70.

tical portion p In the present illustrated embodiment of the invention, this fabric guide is in the form of an English binder, binding 0! led into the receiving end e of the guide, and the binding is folded intermediate its ed es and is reversed as it passes from the de ivering end 7 of the guide so that the binding may be stitched to a abric by a stitching mechanism which includes a needle 9. The'bodyfabric is preferably directed by an edge guide 0 which is attached to the work support in front of the stitching mechanism. In order that the fabric guide may be-moved away from the stitchin mechanism to give access to the looper, sai guide is mounted on a support It which is in turn mounted on a pivot z carred bya bracket is which in turn is secured to'the work support by screws k, is. These screws pass through suitable slots in the bracket is, and permit the bracket to be adjusted transversely of the cloth plate toward and from the rear edge of the cloth plate. The fabric guide 0 is atby means of an an le bracket plate 8. Said angle plate is provi ed with slots u, u and screws t, t passing through these slots secure the angle plate 8 to the holder. This angle plate 8 has a verprovided with vertical slots 1' through which screws 9 pass. I By loosening the screws g the guide may be raised and lowered vertically re ative to the holder. By loosening the screws t, t, the guide ma be shifted bodily in a direction of its lengt or toward and from the line of feed. These adjustments permit the guide to be properly mounted on the holder or support therefor. The bracket is as clearly shown in Fig. 4 of the drawings, has its upper face inclined, and the holder or support for the fabric guide is mounted on this upper inclined surface of the bracket. The parts are so shaped and positioned that when the fabric guide is in the position shown in Fig. 2, it is positioned relative to the work support so as to properl guide and direct the strip passing throug the guide beneath the presser foot and about the edge of the" body fabric. When it is desired to get close to the looper, the sup ort for the fabric guide is swung about its pivot i and as the guide moves laterally away from the needle, it will, on account of the inclined upper surface of the bracket is, be gradually raised away from the work support. Thus it is that the guide is lifted when it is moved laterally, and this gives a very free movement of the guide so that it is not in any way obstructed by any of the parts of the work sti port. By the arrangement-just described t5 guide or folder may be readily placed in the usual opening through the cloth plate whenby access is ad to the looper for threading the same. The guide may be placed in this pening with its longitudinal center plane ubstantially in the plane of the work supwhich receives a tape or.

, provided with an e as it is moved laterally port, that is, the upper surface of the work support. In cases where an English binder is used, as shown in the drawings, the 11 per half of the binder is above the plane 0 the work" support and the lower half of the binder is below the plane of the work support, lying in the opening directly over the looper and usually closed by a cover plate. This is the normal operative position ,of the guide. When it is desired to get access to the looper for threading, the guide is moved away from the stitching point and the supporting means is so constructed that as it moves away it also moves upward out of the opening and to a position above the work support. This completely uncovers the looper so that it may be readily threaded. The support for the fabric guide is yieldingly held in its normal operative position. This is accomplished by means of an pin '0 and a spring latch 3/ which is opening w adapted to engage the pin '0. This latch has a finger piece as whereby the latch may be readily raised to'release the latch from the pin. When the fabric guide is moved to normal-operative position, the pin will automatically lift the spring and engage the opening to so as to lock the guide in this position. The latch is raised by the finger piece a; so that the guide can be swung to inactive position.

In Figures 5 and 6, there is shown a modified means for mounting the support for the fabric guide so that it will be raised from the work support when moved laterally. In this form of the invention, the bracket is is done awaywith, and a post I substituted for the pivot pin z. This post is provided with a spiral groove m. The holder or support h or the fabric guide carries a pin n engaging the spiral groove. When the holder or support swings about the post I as indicated by the arrow B, then the pin n following the groove will raise the holder away from the cloth plate.

Other means may be provided than those illustrated for lifting the holder or support for the fabric guide away from the work sugport when it is movedlaterally away from t needle, and forreturning it to its proper position relative to the work support when it is moved back again into normal operative position.

While the binder guide has been shown in detail, it is understood, of course, that other forms of fabric guides may be used, suchas hemmers or the like, as the invention is more particularly in the support for the guide and the manner of raising and lowering the same ward the stitching point.

It is obvious that minor changes in the details of construction may be made without departing from the spirit of the invention as set forthin the appended claim.

Having thus described the invention, what away from and to- I claim as new and desire to secure by Letters Patent, is

In a sewing machine the combination of a. work support, a stitch formin mechanism, a fabric guide normally dispose adjacent said stitch forming mechanism in an opening in said work support and with its longitudinal center plane l yingin the plane of the work support, and supporting devices for said fabric guide including means whereby the fabric guide may be moved away from the stitching point in a direction obliquely to the plane of the work support whereby said guide is moved to an inoperative position above the plane of the work support for rendering the stitching element beneath the work support accessible for threading through said opening.

In testimony whereof, I aflix my signature.
