Application filed November 16, 1911. Serial No. 660,579.

ofwhich the following is a description, reference beinghad to the accompanying drawing and tothe letters and figures of reference markedthereon.

rEhe invention r lates to new and useful improvements in sewing machines, and has for an object to provide-a fabric-guiding devies. which may he movedaway from and toward` the stitching mechanism, together with devices for In.moving the fabric-guiding device, whichlevices include means for raising the presser foot.

A further object of the invention is to pro vide 'devices of the above character which also be operated to release the tension on the thread, so that the operator by the movement of a single lever may raise the presser foot, release the tension on the thread and withdraw the fabric-guiding device from the stitching mechanism.

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

1n the drawings which show by way of illustration one embodiment of the invention, Figure 1 is a front view of a machine having the invention applied thereto; Fig. 2v is a rear view of the same; Fig. 3 is a horizontal sectionalview through the standard, showing the work support in plan; Fig. 4 is a detail perspective view, showing the conibined mechanism for moving the guide, raising the presser `foot and releasing the ten sions; Fig. 5 is a sectional view through the binding guide;-F ig. 6 is a detail, showing the tensions and the releasing lever therefor;

Fig. 7 a detail in perspective, showing the lever for moving the binding guide; Fig. 8

is a detail in perspective of the arm for releasing the tensions; and Fig. 9 is a sectional view through the presser foot lifting lever, showing the connection for releasing the tensions.

The sewing machine to which the invention is applied, consists of the bed. plate 1 on which is supported an overhanging arm i2. At the forward end of the overhanging arm is a needle bar 3, which is reciprocated by a needle lever 4. The needle lever e is con: nected with the main shaft of the machine. Said needle bar is provided, as herein shown, with two needles 5, 5. Cooperating with the needles beneath the work support may be any desired forni of looper mechanism. Y

Mounted on the bed plate 1 is a work support/6 on which the fabric is supported and guided to the stitching mechanism. r1`he fabric is held in engagement with the feed dog of the machine by\a presser foot 7, which is carried by a presser bar 8. The presser bar 8 is formed with a projecting pin 9, on which rests a leaf spring 10, which yieldingly holds the presser foot against the fabric on'the work support. These parts are of the usual construction, and will not need further description.

ln order that the presser foot may be raised from the work support, for the purpose of manipulating the farbric, or for inserting or removing the same, a lever 11 is pivoted at 12 to the overhanging arm, and is provided with a forwardly projecting portion which is adapted to engage the pin 9, carried by the presser bar. This lever is held depressed at its forward end by a spring 13. The lever 11 at its rear end is connected to a chain 14. rlhe needle threads pass through suitable tensions 15 and 16, and `fthrough suitable guides of the usual construction, to the needles. ln order' that these tensions may be released when the presser foot is raised, a tension-releasing lever 17 is provided, which lever is pivoted at 18 to the overhanging arm. This lever carries an arm 19, which is formed with spaced fingers 2O 4and 21. The outer ends of the ngers 2O and 21 are wedge-shaped, and are so disposed-that when the lever 17 Vis swung about its fulcrum, the wedge-shaped ends of these fingers will enter respectively between the clamping' disks of the tensions 15 and 16. The other end of the lever 17 isformed with a projecting lug 22, which is located in the path of a bracket 23, adjustably attached to the presser foot raising lever 11. This lug 22 also extends over the lever 11, and will' be effectively housed between Athe upper bent end of the bracket and the `1lever proper, so-

that as the lever is moved up and down the lug Q2 will cause the tension-,releasing lever lo be vibrated.

Freni the above construction., it will ap.-

mit

parent that on the downward movement of the chain or flexible connection 14, the lever 11 will/be swung so as to bring the free end thereof intolengagement with the pin 9 for raising the presser bar, and said lever will also swing the tension-releasing lever 17 so as to carry the

fingers

20 and 21 between the 'clamping disks of the tensions 15 andk 16, andthereby release all tension on the needle threads.- This releasing of the tension on the needle threads at the same time that the presserfoot is. raised, allows the fabric to be readily removed from the machine.

As herein shown, the machine is provided with a guiding device 24, through which a strip of fabric may be guided and the edges thereof folded. This strip of fabric is preferably guided underneath the main body fabric, and will be stitched to the main body fabric by the stitching mechanism. In order that the main body fabric and the attached strip may be bound, I have provided a binder 25. This binder is mounted on a plate .26 which is free to slide transversely of the line of feed or the line of the seam. A stop 27 is attached to the plate and engages the throat plate of the machine to limitY the inward movement of the plate. The binder, as herein shown, is of the type described in the'patent to lV. E. Dickson, No. 891,605, granted June 23d, 1908. Said binder is formed with a U-shaped passage 28, and with an open receiving mouth 29. Said binder is 'also tapered at its delivery end so as to invert the binding strip. The construction and operation of this binder is fully set forth in said patent and will not lneed further description. In order to guide a binding strip to the binder, I have also provided a guiding member 30, which is attached-to av bracket 31. These parts are also shown in said patent, and will not need further description.

It #is .sometimes desirable to move the binder away from the stitching mechanism, as, for example, in turning a cog-ner, or upon the finishing of the garment, so that the binding strip may be cut between the binder and the stitching point, and the cut end of the binding properly turned in for thefinal finishingof the article. In order that this may be readily accomplished, I have provided a lever 32, which is pivoted at 33 to the upper face of the work support. The other end of the lever 32 is pivoted at 34 to the sliding plate 2G, on which the binder is mountedr To. aid in guiding the sliding plate, I have formed the same with an ex-.

tension 35, which carries a pin 36 extending through a slot 37 in the bed plate. I have also provided a stop screw 38, which eX-` ytends into the bed plate, and when the lever 32 is swung to move the plate 26, said plate strikes against the stop screw 38, and the outward movement of the plate and binder away from the stitching mechanism is theres by limited. The work support is also formed i with an arc-shaped slot 39. Rigidly connected to the lever 32 is a bracket 40, which projects downwardly through the arc-shaped slot 39, and is curved to conform to the same. A vspring 41 arranged beneath the work support is connected at one endto the bracket 40, and said spring at its other end is secured to a fixed, lug on the under face .of the work support? This spring normally l moves the lever 32 so as to hold the stop 27 in Contact with the throat 'plate of the machine and the binder, in normal position for guiding the binding strip to thelstitching mechanism. A chain or other iieXible connection 42 is attached to the other end of the bracket 40, and to a lever 43. This lever 43 is pivoted on apbracket 44 carried by the bed plate 1. Said lever is formed with an outwardly projecting arm 45, which is' gaged to lift the presserl foot. This lost motion between the lever 11 and the presser foot is taken advantage of infthe present construction, to provide-a movement of the This treadle or binder without raising the presser foot. In

other words, when the ,chain'is first pressed downwardly, the lever 45 is at once swung yabout its fulcrum, which will swing the 1ever 3 2, and at once withdraw the binder fromthe stitching mechanism. The binder through this movement of the lever 45 will be moved a considerable distance before the lever 11 engages the pin 9 to raise the presser foot.

The

fingers

20 and 21 of the tension-re leasing lever are spaced some distance from the tensions, so that the first movement of the tensioirreleasing lever is ineffective to release the tensions. Therefore, the binder may be moved a short distance away from the stitching mechanism and returned, if desired, without either the raising of the presser foot or theopening of the tensions. A further movement, however, of the treadle or knee shift, will move the binder still farther away from the stitching mechanism, raise the presser foot and release the ten` sions. It will be noted that this treadle or knee shift may be manipulated so as to move the binder away from the stitching mechanism during the stitching operation, for the amener first movement offrthe binder ydoes not raise :thepresserfoot lso astc render the iced away from the/stitching mechanism.
