FRANK M. KENNEDY, OF NEW HARTFORD, NEW YORK, ASSIGNOR TO KENNEDY NOVELTY COMPANY, OF NEW HARTFORD, NEW YORK.

CORD-GUIDING ATTACHMENT FOR BUTTONHOLE-SEWING MACHINES.

To all whom it may concern Be it known that I, FRANK M. KENNEDY, a citizen of the United States, residing at New Hartford, in'the county of Oneida and State of New York, have invented certain new and useful Improvements in Cord- Guiding Attachments for Buttonhole-Sewing Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to a cord feeding attachment for button-hole sewing machines, and I declare the following to be a full, clear, concise and exact description thereof sufiicient to enable any one skilled in the art to which it appertains to make and use the same reference being had to the accompanying drawings in which like reference characters refer to like parts throughout.

The object of the invention is to provide a guide adapted to deliver a stay cord relative to certain movements of the presser footand feed of a button-hole sewing machine, whereby said cord may be presented above the cloth and always in advance of the relative path of the needle.

Furthermore, the invention contemplates certain novel improvements over Letters Patent, No. 1,025,574, granted to me, May 7, 1912.

The device is adapted to be attached to any well known type of button-hole sewing machine having a presser foot, feed, and cloth plate which operate in unity to reciprocate the cloth longitudinally of the button-hole, as well as to move transversely thereof, whereby to effect the requisite movements necessary for creating the button-hole.

Other objects will be observed by reference to the drawings in which:

Referring more particularly to the drawings, the feed portion of presser-foot 1- is represented by 2, and the clot-h plate by 3 of a button-hole sewing machine. Presser foot 1 and feed portion 2 are formed with the usual aperture 4 having a width and length sufliciently adapted for permit? ting the access of needle 5 to the cloth disposed beneath presser foot 1, relative to the movements of feed portion 2 and cloth plate 3 of the machine. Postfi is mounted on plate 3 and is surrounded by a coiled spring 7 which creates a pressure on plate 8 formed with arms 9 and 10 extending to opposite sides of presser-foot 1., whereby to eXert a yielding downward pres- Presser foot 1, arms 9 and 10, and plate 8 are elevated in the well known manner by mechanism not herein shown in detail. Furthermore, clo-th plate 3 is shifted longitudinally and transversely by cam mechanism situated beneath the machine, whereby the cloth is moved relative to needle 5 for enabling the stitching by said needle 5 of the respective sides of the button-hole. Presser foot 1 and feed portion 2 are shifted simultaneously with cloth plate 3 for the aforesaid purpose. Needle 5 in addition to the regular reciprocation, is oscillated through an are equal to the length of the stitch at one side of the button-hole, or the distance represented from point 11 to point 12 in Fig. 15. r

The parts above. referred to are well known in the art and are mentioned merely for a better understanding of the attachment now to be described.

In Letters Patent granted to me May 7, 1912, No. 1,025,574, there is shown certain parts which are employed also here, namely filler block 13, depending plate or bracket 15, slotted for receiving retaining screws 16-16, whereby said bracket may be adjustably held to head 17. The lower end of bracket has a horizontal portion 18 bent outwardly, and a horizontal portion 19 bent inwardly. Said horizontal portion 19 supports in a depending manner a journal bearing block 20, by means of screw21. Block 20 is bifurcated, whereby to support therebetween sleeve 2-2 holding adjustable guide 23 by means of set screw 24 and mounted upon rock shaft 25 having its outward end bent upwardly as at 26 adapted to be engaged by a retractile spring 27 whose remote end is in engagement with rod 28 supported by its bearing in post 29 extending laterally from the side of the machine. The end of rod 28 is screw threaded for the corresponding mounting of caps or lock nuts 30-30, so that rod 28 may be moved longitudinally to adjust the tension of spring 25. Sleeve 22 is held to rock shaft 25 by set screw 31. The lower end of guide 23 is disposed adjacent needle 5, and is provided with a feeding aperture 33 through which is delivered a stay cord 34 from cord tension device 35, not disclosed in the former application.

In order to provide means, whereby guide 23 will register with opening 4 of presserfoot -1 and of feed portion 2, at the completion of a button'hole in the cloth, when presser-foot 1 is in its rearmost position, there is mounted on rock shaft 25, between sleeve 22 and the portion adjacent the upward bend, namely 26, a novel sleeve 36 holding a rod 37 by set screw 38. The outer end of rod 37 is connected by a wire 32 or other suitable means to post 39 of belt shifter 39 at the rear of the machine, so that the movement of belt shifter 39 will be transmitted through said rod or wire 32, rod 37 and sleeve 36, to rock shaft 25 and its connected parts sufiiciently to cause the lower end of guide 23 to move rearwardly whereby to register with aperture 4 of presser-foot 1-, and thereby permit the elevation of presser foot 1 to move the cloth underneath to the location of the next button-hole.

In the button-hole sewing machine of the foregoing type, the needle 5 remains stationary with reference to the movement, longitudinal and transverse of the buttonhole, so that it is necessary only to move guide 23 with reference to needle 5 to permit stay cord 34 to be delivered in advance of needle 5, throughout the button-hole. To

effect this purpose, there is provided further novel means for rocking shaft 25. Said means comprises a standard 40 secured to cloth plate 3 of the machine and having its upper end recessed at 41 for the reception of stop lever 42 pivoted at 43 to the outwardly extending portion 18 of bracket 15. To the forward portion of lever 42, in front of pivot 43, is laterally secured a guide flange 44 having a portion projecting laterally above its base to form a guide way for dog 45 provided with a corner recess 45 and a central recess 47 adapted to clear pivot 43. Dog 45 is constrained from leaving the upper surface of lever 42 in a lateral manner by plate 48 secured at one end to bracket 50 mounted on lever 42; The free end of plate 48 is supported by laminated spring 49 secured also at one end to stud 50. Dog 45 is connected to belt shifter 39 by an arm 51 having an adjustable joint at 52, whereby the movement of belt shifter 39 actuates or longitudinally reciprocates dog 45.

Located underneath lever 42 is a certain novel longitudinally adjustable bar 53 secured to lever 42 by set screws 5454 and having one side projecting a short distance outward from the corresponding side of lever 42.

The operation of the device is as follows: The cloth is disposed beneath presser foot 1 at the proper place for the location of a button-hole therein, whereupon the operator lowers the presser-foot and throws on the power, whereby belt shipper 39 is moved forwardly to ship the belt from idle pulley 56 to power pulley 57. This movement of the belt shipper 39 is suflicient to cause dog 45, connected thereto by rod 51, to abut against the upper portion 26 of lever 25, whereby to rock said lever and its connected parts including guide 23, so that said guide 23 is moved to the rear of needie 5 or to the position indicated in Fig. 1 in advance of the relative direction of travel of needle 5 along the first side of the button-hole. The parts maintain this relative position while the cloth is moving for wardly throughout the first side of the button-hole, as seen more particularly in Fig. 15. At the completion of the aforesaid side, cloth plate 3 and the correlated parts are shifted transversely, whereby needle 5 assumes a position above the opposite side of the button-hole. The transverse movement of cloth plate 3, causes a simultaneous movement of standard 40, which correspondingly moves lever 42 and its immediate parts upon pivot 43. To the rear end of said lever 42, there is attached a coiled spring 60 tending to normally draw the rear end of lever 42 inward, when standard 40 moves forward, as shown in dotted lines in Fig. 3. The opposite end of spring 60 is secured to any suitable part of the machine as to the forked end 62 of arm 63. The aforesaid movement of lever 42 causes recess 46 of dog 45 to register with portion 26 of rock shaft 25, whereby said arm is rocked or journaled to permit guide 23 to assume a. position in front of needle 5. The function of longitudinally adjustable bar 53, at this instance is employed to permit lever 42 to move to the position shown in dotted lines in Fig. 3, immediately the respective sides of recess 41 of standard 40 reach the forward end as at 65 of the pro jecting portion of longitudinally adjustable bar 53 and before presser plate 1 and connected parts are shifted completely transversely of the button-hole for causing the needle 5 to assume a position above the opposite side of the button-hole, so that guide 23 will be out of the way of needle 5, when barring the button-hole, as at 66. In this last mentioned position, the upper portion 26 of rock shaft 25 lies in recess 46 of dog 45.

The employment of longitudinally adjustable bar 53 will be found particularly useful in view of the fact that guide 23 would not otherwise move ahead until the presser-plate 1 and connected parts had shifted completely transversely of the button-hole for causing the needle 5 to assume a position above the opposite side of the said button-hole, as in the patent herein above referred to.

In Figs. 5, 6, 7, and 8, there is shown a modification of the means for causing guide 23 to move in a manner to precede needle 5, when stitching the sides of the button-hole. The modification embodies an arm pivotally secured to the bifurcated portion of bearing 71, which is fulcrumed upon bracket 72 secured to the head of the machine. whereby there is formed a universal joint. To the lower end of arm 7 0 there is detachably secured a lug 73 holding an adjustable guide 74 by means of set screw 75. Guide 74 has the same function as guide 13 of the former construction. A bracket 76 is secured to the head of the machine and pivotally supports at 77 a lever 78, whose outer end is connected by wire 79 or other means to post 39 of belt shipper 39 of the machine. Lever 73 is provided'with a curved recess 80, whereby the edge of said recess will e11- gage with arm 70 and, at the proper interval, force same outwardly and rearwardly. The mechanism for causing arm 70 toassume the position shown in dotted lines in Fig. 5, embodies a lever 81 having notches 82 and 83 and a tapering end portion 84. Lever 81 is pivotally connected to bell crank lever 85 fulcrumed at 86 to the upper portion 87 of bracket 88, having a lower portion 89, provided with slot 90, whereby said bracket 88 may be held in an adjustable manner by .position indicated in Fig.

set screws 9191. The portion 89 of the bracket 88 is secured to the base plate of the sewing machine, whereby the bracket 88 is held stationary, and independent of the movement of the presser plate 3. The end 92 of bell crank lever 85 is pivotally secured to link 93, pivotally mounted to the upper surface of post 94 by screw 95. Post 94 is mounted upon cloth plate 3, whereby its movements will be imparted to post 94 and its connected parts including lever 81. Lever 81 is held normally in the position shown in full lines in Fig. 7 by a spring 96 connecting end 97 of lever 81 and set screw 98 mounted to hell crank lever 85, and by adjustable member 99 mounted upon bell crank lever 85 by set screw 98, and having a reduced end 100 adapted to abut against a corresponding recess 101 formed in lever 81. In this position the free end of lever 81 will lie adjacent the inner surface of arm 70, held normally in toward the head by coil spring 102, connecting arm 7 O and any suitable portion of the head as screw 103 supporting bracket 76. Arm 70 is moved to the position shown in full lines in Fig. 5 by the edge of lever 7 S, which is journaled upon its pivot 77 to the position shown in full lines in Fig. 7 by wire 79 connecting the outer end of lever 78 with belt shipper 39, as said shipper moves rearwardly to throw the belt from power pulley 57 to idler 56. Guide 74 remains in this last named position, or in the rear or relative advance of needle 5, while same is stitchingthe first side of the buttonhole. At the conclusion of stitching of the button-hole, the automatic transverse shifting of cloth plate v3, presser-foot 1 and feed 2 causes a simul taneous movement of post 94, and its connected parts, namely link 93, bell crank lever 85, and lever 81 to the positionindicated in dotted lines in Fig. 7, so that lever 81 is drawn rearwardly a sufficient distance to permit notch 83 thereof to engage the edge of arm 7 O. The subsequent automatic transverse movement of plate 3, at the completion of the first side of the button-hole, whereby the cloth is shifted transversely to permit needle 5 to be disposed over the opposite side of the buttonhole, causes a forward movement of lever 81, which being in engagement at notch 82 with arm 70, will actuate said arm 70 forwardly to the posi tion shown in dotted lines in Fig. 5. In this last mentioned position of arm 70, guide 74 will be moved to the front of needle 5. Obviously, lever 78 will be in the position inclicated by dotted lines in Fig. 7, when this last named forward movement of arm 70 occurs, for when belt shipper 39 moves forwardly to throw the belt from idle pulley 56 to power pulley 57, the same will cause wire 79 to move lever 7 S to the dotted line 7. Arm 70 will remain in this second position, while needle 5 is stitching the second side of the buttonhole. At the conclusion of the second side of the button-hole, shipper 39 will automatically move rearwardly, and by means of wire 79, draw lever 78 again to the position indicated by full lines in Fig. 7, whereby guide '74 will be positioned for the next but ton-hole to be formed. The automatic transverse shifting of the cloth plate 3 and correlated parts at the conclusion of the formation of a button-hole, as stated, will move lever 81 to the position indicated in dotted lines in Fig. 7, whereby said lever 81 will be drawn rearwardly sufiiciently to permit notch 88 thereof to engage the edge of arm 70, so as to be ready to push arm forward or into the dotted line position indicated in Fig. 5, at the conclusion of forming the first side of the button-hole.

In the modified form ust above described, guide T l does not move under needle 5 in its passage from one side to the other of said needle, but oscillates around needle 5. The mechanism provided to elifect this oscilla tory movement, contemplates a roller 105, loosely mounted to a pivot 106, secured to bracket 70, against which abuts the end of a screw 107, threaded to arm 70, so as to regulate the degree of are described by the end of: guide M about needle 5. A depending member 108 is secured to one end of lever 78, whereby to provide a stop for lever 81, so that said lever will just clear arm 70, when said lever is in the full line position indicated in Fig. 7.

A still further modification of the cording attachment is shown in Figs. 11 and 12, in which. construction, arm 70 is moved rearwardly and forwardly to either side of needle 5 by link 110 pivotally connected at 111 to bell crank lever 1.12, fulcrumed at 113 to bracket 114, secured to the head of themachine. End 115 of lever 112 is pivotally connected to link 116 fulcrumed at 117 to post 118, mounted upon cloth plate 3 of the machine. The movement of cloth-plate 8 will cause a corresponding movement of post 118, link 116, bell crank lever 112, and link 110, whereby the movements of cloth-plate 3 will. be communicated to arm 70 to cause same to move guide 74 holding the cord relative to needle 5. Arm 70, as in the former modified construction, is oscillated about needle 5. To effect which movement, a roller 105 is employed and adapted to ride over a curved shaped projection 120 mounted in alineinent therewith on arm 70. Projection 120 of arm 70 is aided in passing roller 105 mounted to bracket 76 by the cam portion 1.21 of sliding member 122, provided with elongated slot 123 adapted for the passage of headed bolt 12%, secured to bracket 125, mounted upon. the head of the machine. Member 122 is connected by rod or arm 126, as shown at 51 in Fig. 1, to belt shipper 39, whereby cam portion 121 will be moved in unison with shipper 39, to force arm 70 outwardly against the tension of spring 130, at the time arm 70 is moved to the position shown in full lines in Fig. 5.

The modification illustrated in Figs. 5, 6 and 11 is particularly desirable in view or" the fact that guide 74 being shifted from one side of needle 5 to the other, by the action of cloth plate 3, permits the movements of guide 74: to be gradual, whereby the cord 8 1 is completely covered by the needle stitches in the fabric about the button-hole. Particularly is this so with reference to the ends of the buttondiole, where the transfer of guide 7st takes place, from one side of needle 5 to the other.
