LANSING ONDERDONK. OF NEW YORK, N. Y., ASSIGNOB TO UNION SPECIAL MACHINE COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

SEWING-MACHINE.

Specification of Letters Patent.

Patented June 28, 1910.

Application filed July 26, 1904. Serial No. 218,192.

To all whom it may concern: 1

Be it known that I, LANSING ONDERDONK, a citizen of the United States, residing at New York, in the county of New York, State of New York, have invented certain new and useful Improvements in Sewing-Machines, of which the following is a description, reference being had to the accompanying drawing and to the letters and figures ot' reference marked thereon.

My invention relates to an improvement in sewing machines and particularly to sewing machines for oversea-ming or finishing the edges of garments, especially knit goods.

Machines for this purpose are not new in the art, many having been devised, but all of them are subject to various defects, some are so complicated as to require skill beyond that of the ordinary mechanic to run them properly; some, While less complicated, are only capable or running at too low speed to render them economical, and others are open to various other objections.

The object of the present invention is to provide an overseaming machine which shall be simple,durable and capable of running at the highest speed with minimum wear and liability to get out of order, which can be easily taken care of by the ordinary operator, which is simple as to the control of the thread and as to the eration of its parts.

Certain features 0 the invention relate more especially to that type of overseaming machine in which three implements are used cooperating to form overseaming stitches; which implements may be a reciprocating thread carrying eye pointed needle, a thread carrying looper cooperating with the needle above the work support, and a spreader eooperating with the needle beneath the work support and with said looper or in-place of said spreader, a thread carrying looper may be used.

Other features of the invention relate solely to that type of overseaming machine wherein two threaded loopers cooperate with the needle in making a three thread overseaming stitch.

In the use of the needle, looper and spreader or looper hook, the latter takes a loop of needle thread below the throat plate and carries it out beyond-the edge of the throat plate in such position that the looper may carry its thread through the needle loop in the spreader, into position to be engaged by the needle in its next descent, thus making a two thread overedge seam, suitable for an ornamental edging or for uniting the edges of superposed pieces of material. In case a second thread carrying looper is substituted for the spreader, said second thread carrying looper passes into the nee dle loop carrying its thread therein.

The present invention consists in the numerous details of construction and various arrangements, and combinations of parts which go to make up a high speed, durable machine, which can handle the thread quickly and effectively, without requiring too much skill on the part of the operator, and to provide on the whole a machine capable of most effective work.

The main features per se and in combination, will be hereinafter described and pointed out in the claims.

The invention is illustrated in the accompanying drawings in which Figure 1 is a front elevation of a sewing machine embodying my invention, the cloth plate being removed to show the operation of the stitch forming elements. Fig. 1 is'a similar view of the entire machine, showing a different style of frame, and various other features differing from those shown in Fig. 1, this Fig. 1 representing the preferred form of machine; Fig. 1 is a view similar to Fig. 1*, showing the cover turned down. Fig. 1 is a plan view of Fig. 1 with the cloth plate and upper part of the machine removed, part of the standard being shown in section.

Fig.29 is a sectional view through the cloth plate showing the means for adjusting the lower trimmer member laterally; F ig. 30 is a detail of the adjusting device; Fig. 31 is a detail of the pin support for the lower blade holder; Fig. 32 is a perspective view of the lower trimmer parts in detail; Fig. 33 is a detail perspective showing the cloth plate extension, throat plate and lower trimmer; Figs. 34 and 35 are detail views illustrating the three and two thread stitches respectively; Fig. 36 is a detail view of the loop retainer; Fig. 37 is a perspective of the cloth plate and diverting guide; Fig. 38 is a view taken from the front of the machine showing the inclination of the looper shaft relative to the cloth plate. Fig. 39 is a detail view showing the looper in section and its position relative to the needle when the needle is passing the same. Fig. 40 is a top plan view showing the fabric and the posi tion of the needle and thread carrying looper cooperating therewith above the work support, when said looper is moving backward and laying its thread over the stitch finger, and in dotted lines, the forward position of the looper.

The frame of the machine is adapted for high speed and to withstand vibration. From the base A rises the goose neck B, which forms at its base one bearing for the driving shaft B; C is a central bearing for said shaft and the usual front end bearing is provided.

The goose neck B about midway its overhanging arm is cut out formnig a recess D to receive. the upper end or head E, of the adjustable upright rod F which is connected within the recess to the ball stud G, attached to the needle lever H, which rod F at its lower end embraces the eccentric I on the main shaft adjacent the central bearing. This rod is adjustable as to length, and by such an adjustment the cooperative time of movement of the needle and the spreader 7) or looper 3) relative to the movement of the looper may be varied. This central bearing prevents any spring of the main shaft and takes the thrust of the needle lever connectionand the balance weight K on the shaft.

The rear portion of the overhanging arm of the gooseneck has an opening L through it into the recess D to permit the passage of a screw driver to loosen the screws in the top of theneed'le lever connection to allow the withdrawal of the needle lever connection ball from its socket or ball bearing in the top of the connection, to permit the removal of the needle lever from the machine. The needle lever is pivoted to the gooseneck on the usual needle lever stud and carries the vertically reciprocating eye pointed needle (1. The stitch forming mechanism of this machine comprises in case a two thread overseam stitch is to be made. a needle (1., a spreader, 7), and a looper 1:; but if a three thread overseam stitch is to be made, a. looper 7) is substituted for the spreader. In the formation of the two thread stitch, the loops of needle thread are taken from below the cloth plate by the spreader Z), op erating in a diagonal path across the line of feed to carry the needle loop to the edge of the material, where it is entered by the looper c, operating from a point below said needle loop, and carrying a loop of its thread, over the top surface of the material where the looper thread loop is entered by a loop of needle thread, thus making the stitch which is desirable for ornamenting cut edges. or for seaming superposed pieces of material. The three thread stitch is made in very much the same manner except that instead of the spreader 7) to carry the needle loop to the edge of the material the needle loop is entered by the thread carrying looper 7/, and a loop of thread of the latter is presented to the looper c to be entered by the latter on its way around the edge and over the top surface of the material to present its loop for the passage of the needle through it.

The looper c is substantially the same, whether a spreader Z) or a looper b is used. The looper c is carried by a frame 5, mounted on a shaft (3 which shaft is supported in suitable bearings 7, 7, (see Fig. 38), secured to the bed plate of the machine. The frame as shown in Figs. 1, 2, 3 and 38, comprises two projecting arms. One of said arms is formed with a socket to receive the looper (z, and the other arm projects laterally so as to lie substantially in a vertical plane passing through the axis of the main shaft B. This arm is provided with a hall stud, which engages one end of a link 3. The other end of the link 3 engages a ball stud on a crank pin 2. carried by a crank 1 fixed to the end of the main shaft B.

In order that the looper 0 may be moved in a direction so as to pass over the work support and position its loop for the entrance of the needle, I have extended the arm which is connected to the looper frame to a point which is substantially over the axis of the main shaft. The link 3 which connects the ball on the end of the crank pin, with the ball stud on the looper frame, is. therefore; substantially vertical, and the rotation of the crank pin will produce a vertical thrust in the link 3, which will oscillate the loo er frame about an axis which is substantial y horizontal, and thus carry the looper from a position below the work support to a position above the work support.

In Fig. 1 I have shown the looper frame 5 as made in two parts, 5* and S, separated from each other, but fixed to the shaft 6. By making these parts separate, I am able to adjust the part carrying the looper on the shaft 6, and thus change the working position of the looper 0 relative to the looper 7) and the needle 11. The spreader b and looper b may either be termed a thread-manipulating device or implement, as both of these elements in cotiperating with the needle and looper 0 manipulate a thread. This threadmanipulating device, as shown in Figs. 1, 2 and 3, has its shank fitting in a socket in the upper part of the frame 8. The frame 8 at its lower end is fixed to the shaft 9 journaled in lugs on the stand 10, adjustably secured to the bed plate of the machine. This spreader or looper supporting frame 8 has its journals diagonally arranged so as to give the spreader or looper a diagonal movement below the cloth plate to seize the loop of needle thread and carry it to one side to be engaged by the looper 0, or to carry its own thread to one side to be entered by the looper c. The said frame is provided with a ball stud 11, over which fits one end of the pitman 12 which atits opposite end is connected to the extension 13-of the needle lever H, through the crank 14 and link 15. By this arrangement a differential motion is im parted and thus at the proper-position in its movement a dwell is given to the spreader b or looper b to give time for the looper c to get intothe loop of thread on the spreader or looper b. This dwell is accomplished by reason of the position of the pivotal center 13' of the needle lever, the pivot connection 15' and ivot connection 15 These points are so disposed that when the spreader or looper is in its forward position, said points are substantially in line, so that little or no movement will be imparted to the rock arm or crank 14.

The preferred construction of stand for the looper b and spreader b is shown in Fig. 1 and 21 and 22. The base 17 is pivoted on the screw 16, and held in adjusted position by the set screw 18, this pivotal adustmentof the base of the stand is to adjust the spreader or looper b or b to the needle. Dovetailed into this base 17 as at 19 is the plate 20 adjustable by means of the set screws 21 in the slots 22. This plate 20 has the vertical lug 23 supporting the looper rocker stud 24 carrying the support 25 for the spreader b or looper b. This is oscillated back and forth by the pitman connection 12 to the needle lever extension in the manner described above. The 'cross adjustment of the plate 20 is for the same purpose as the cross adjustment of the stand 10 above described, namely to adjust the spreader b or looper b to the looper c.

The bearing lugs 7 7, supporting the shaft 6, carrying the looper c are so disposed that the shaft 6 is inclined to the line of feed and slightly inclined to the work support or cloth I and 38. This inclining of the looper shaft 0 contributes largely to the successful operation of the machine whether said looper cooperates with a looper Z) or a spreader b below the work support. The inclining of the looper shaft 6 from the rear toward the front of the machine relative togthe work support, will incline the 100 or body from .its upper edge to its lowere ge toward the path of the needle, as shown in Fig. 39 and this positioning of the looper body is a great advantage in enabling the needle to ass between the looper body and its thread. \Vhen the looper 0 moves to the forward end of its stroke, the thread running from the eyethereof to the previous enchaining of the threads is held taut, and in order to make the stitch, the needle must pass between the body of-the looper and this taut portion of the looper thread. The inclined face of the plate 33, as clearly shown in Figs. 2

looper body allows the needle to be set so that the point thereof runs very close to the lower edge of the looper body and therefore, the needle will with certainty pass between the looper thread and the looper body. If the needle should vibrate slightly under high speed, the inclined face of the loo er willserve as a means to deflect the nee le back into its proper ath and insure the needle passing on the right side of the body of the looper. Then again, where the axis of the looper shaft is inclined as above noted,- the looper when retracted will lay its thread well up on the stitch finger and toward the front of the machine as shown in Fi 40. This enables the laying of the threads 01'1'11- .ing the over-edge stitch so that the loops of the thread will be substantially at right angles to the edge of the material. The looper may be caused to move still farther toward the front of the machine as it is retracted by reason of the inclination of the looper shaft to the line of feed, as well as to the work support. This inclining of the looper shaft to the line of feed, also carries the point of the looper well behind the needle at the forward end of its stroke as shown in Fig. 40, and thus aids in carrying the looper thread between the eye of the looper and the previous interlocking of the threadswell to the rear, so that the needle will with certainty pass between the looper thread and the body of the looper.

The inclining of the looper shaft relative to the work support is of especial advantage when a looper b is used and a three thread overseaming stitch produced. When a threaded looper is used cooperating with the needle beneath the work support, there is little or nothing to aid the threaded looper in forming a projected loop when said looper is at the forward end of its stroke, and therefore, the looper 0 when it enters the loop of thread formed by the looper b must pass between the body of the looper a and its thread, which hugs quite closely to the body of the looper. By inclining the shaft of the looper c, I am able to cause said looper to move up across the side face of the looper b and thus enter with certainty between the body of the looper b and its thread. It is well understood that in making a three thread overseam, it is not only necessary that the looper 0 pass in rear of the looper b, but said looper 0 must also pass in front of the needle a above the work support. The inclining of the looper shaft will cause the looper'c to move not only across the rear face of the looper b and close thereto,'but also in front of the needle a and position the loop of thread formed by the looper c for the entrance of the needle.

In Figs. 4 to 7 and 11 to 13 inclusive, I have shown the various steps in the formation of a two thread overseam, while in Figs. 15, 16 and 17, I have shown the various steps in the formation of a three thread overseam. In this character of stitching mechanism, the needle loop is loose when the looper is being retracted therefrom, and sometimes said needle loop, instead of being shed from the looper, will be carried back with said looper, and the needle on its next descent will enter its own previously formed loop, thus forming imperfect stitches. In order that the needle loop may be shed with certainty from the looper, as .it is retracted, I have provided a wiper, which is so disposed relative to the looper as to engage the needle loop, and positively push or shed the same from the loo er. Said wiper, as shown in Figs. 16, 17 an in detail in Fig. 36, comprises an arm 26, which is secured by a set screw 27 to the bed casting, and carries at its upper end a piece of leather 28. The looper b moves back and forth in a single plane, and the leather end 28 of the wiper is so disposed that as the looper is retracted,

the needle thread which is then on said looper will be engaged by the leather wiper 28, and pushed from said looper, so that said needle loop could not by any possibility be carried back with the looper into the path of the descending needle.

The throat plate 29,, shown in Fig. 18, used in this machine is provided with the regular slots for the feed dog, a space 30 for the lower knife blade of the trimmer and a stitch finger 31, over which the stitches are formed and. which serves to support the edge of the fabric. The throat plate is also provided with a cut out. portion 32 for the passage of the stitched edge of the material, in order not to stretch or distort the edge. The presser foot does not bear on the work over the cut out portion of the throat-plate, but the delivery end of the tongue, carried by said presser foot sheds its thread directly above the cut out portion. The cloth plate 33 is attached to the bed casting of the machine in the usual manner, being held in position by screws. To its front end is pivoted by means of a screw 34 an extension 35 which projects to the right of the body portion and forms a rest 36 for the hand of the operator or to which a guide may be conveniently attached. This extension 35 is held in operative position by means of a spring 37 attached to the apron or downward extension of the cloth plate. When in operative position the extension is in the position shown in Fig. 1.

To provide convenient means to gain access to the looper and spreader for threading the looper and oiling-the parts, I have attached to this machine a hinged cover 38 attached to the bed casting of the machine along its bottom edge by screws 39, and held in place at the top by a spring pin 40 inserted in the top of the central bearing lug for the main shaft and registering with the hole 41 in cover 38. The cover 38 carries on its outer face a guide 42 for diverting the strip severed from the body fabric away from the feeding mechanism and parts of the stitch-forming mechanism located beneath the work support. This diverting guide is normally spring pressed forward by means of the spring 43 pressing against the bracket 44 screwed to the inner side of the cover 38 by means of the screws 45, which pass through slots 46 in said cover. The diverting guide is shown in two different forms, see Figs. 1, 26 and 27. The pre ferred form is shown in Figs. 26 and 27 and are made with a surface obliquely inclined toward the rear of the machine, which conforms to the direction of travel given the loop spreader, and allows the ready deflecting of the trimmed oflstrip away from the machine. The upright portion 47 of the diverting guide shown in the preferred form, Figs. 26 and 27 and in the modified form in Fi s. 1 and 24, is arranged in line with the back edge of the trimmer blades to allow the trimmer blades to completely sever the fabric-before the deflection of the cut off strip is commenced. I find this an essential feature, as the partially severed fabric refuses to be readily diverted causing improper feeding of the material. On the operative edge of the strip dlvertmg gulde is provided a verticall extending projection 48 which serves to c ose up the space between the inclined edge 49 of the guide and the parts of the trimmer and machine exposed, to prevent the trimmed ofi strip from passing into the working parts of the machine. It will be noted by reference to Fig. 37 that a space is provided between the cloth plate extension 35 and the diverting guide 42, for the passage of the strlp severed from the body fabric and diverted by the diverting guide 42. 0

The trimming device used in my machine is very nearly the same as that used in the Union Special interlock machine, shown in an application No. 81,772, filed November 9, 1901, by Russel G. Woodward and myself. To overcome the striking of the machine frame with the upper end of the movable knife, when it was thrown out of operative engagement with its operating means, I have provided a knife 50 formed on an arc of a circle and having its upper end extending away from the frame of the machine. This construction also admits of making-the upper knife of greater length, thus admitting of its longer use before being ground away so that it is no longer useful; The holder 51 is provided with a slot 52 conforming with the curvature of the edges of the knife to adjustably hold the knife in position. The stationary part of the trimmer is mounted on the under side of the cloth plate and capable of being adjusted laterally with respect to the line of feed, to vary the width of the seam and the distance from the. edge of the material to the line of needle punctures into the material.

The support for the lower stationary blade 54 has its front side adjustably secured in a slot 55, and secured against displacement by a screw 56 passing through a slotted hole 57 in the apron of the work plate and entering into the support 53. The support 53 is adjusted laterally by means of the screw 58 having its head 59 projecting outside of the work plate apron, and having a cut out portion 60 in engagement with a collar 61 secured by screws 62 to the apron of the cloth plate, and'its end 63 entering into the threaded hole 64 in the support. Turning the screw 58 from front to back adjusts the su port 53 to the right. This construction 0 trimmer and guide forms the subject matter of my divisional application filed Aug. 10, 1905', Serial No. 273,574. It

will be noted, that as the stationary member of the trimmer is moved laterally the guide for diverting the trimmed oft strip is also correspondingly moved, for the reason that the guide 42 is normally spring pressed forward by means of the spring 43 so as to hold the guide 42 against the stationary trimmer.

The feeding mechanism per se forms no part of the present invention and need not be particularly described. It embodies however the tilting feed dog feature of the Union Special single interlock machine as illustrated in the \Voodward Patent No. 802,789, granted October 24th, 1905, and has means for adjusting the said tilting feed dog so that a greater or less amount may come above the cloth plate.

The pull-oft and take up for the needle thread is shown in Fig. 1*. To the front end of a pin 65 passing through the upper right hand end 0 the goose neck is attached an adjustable pronged piece 66, having eyes in the projecting ends for the passage of the thread. An arm 67 adjustably secured to, and vibrating with the needle lever vibrates between the passage of the iece 66 and in this way draws ofl' thread from the spool, thus delivering the thread for the stitches to the tension, free from irregular strains which with the regular tension in the thread would cause unevenl laid stitches. The vibratory arm 67 is adjusted upon its pivot point by means of the slot and screw 69, 70 in its lower end. i

To the center of the gooseneck is attached the plate 71 carrying two thread eyes 72 between which a thread eyelet 73 attached to and vibrating with the needle lever acts. The eyelet in the needle lever has only a limited movement so the plate 71 is adj ustable" as shown in dotted lines in- Fig. 1.

These parts form the take-up for the needle thread. The take-up for the looper thread is shown in Figs. 1 and 1 The thread is led from the supply through the eyelet 91, and thence through the eyelet 93 to an eyelet 90 on the back side of the needle lever extension. The thread passes then to the tension 92. These parts form a pull-off for this looper thread. To the needle lever extension 13 is attached a' plate having a thread guiding eye 74, having take-up .pins 7 5, 75 acting in conjunction with pins 76 on the adjustable plate 77. Y The thread passes in front of the top, and middle, and back take it up. When the needle ever'again moves to the left, the thread is-givenup for the stitches. By adjusting the plate. carry- Y substantially in a vertical ing the three stationary pins the amount of thread taken up can be varied. The plate has a screw hole to give it the adjustability. To increase the take up action on the lower thread the stationary plate is moved to the left, while to decrease it the plate is moved to the right. When alooper b is substituted for the spreader b, the thread supplying the same is first passed through the eye 78, through the eye 7 9 on the'plate held b the tension post, then through the pull-o eye 74, over the top and around the lowest tension post 80, thence to the looper through guiding eye 81.

arious minor modifications and changes may be made without departing from the spirit of my invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
