- This invention relates to improvements in that class of sewing machines described and illustrated in my application filed May 31, 1902, Serial No. 109,756, in which a knife or cutting mechanism is combined with stitching mechanism in such a way that the fabric is cut and overstitched at one operation through the machine.
- the special purpose for which this machine is designed is what is known as neckin and to do this work it is necessary that tie machine be capable of feeding two or more layers of fabric, se )arating said layers, trimming one of the ayers prior to the stitchin operation and guiding or deflecting one of t fie severed edges so that it will not be sewed, and finally overstitching the undefiected severed edge to the layer or layers that have not been out.
- this machine is especially adapted for this necking it is manifest that it may be used for a number of other purposes.
- the objects of the present invention are to improve the machine shown in my hereinbefore mentioned application, to simplify the parts, to rovide a movable cutter which has none of t e complicated parts shown in my said a plication; to provide a simple form of fixed nife which may be easily detached and readily replaced; to provide means for yieldingly holding one of these knives in contact with the other; to rovide a device for making the cutting device ineffective; and finally to provide a presser foot especially adapted to coact with this special form of cutting mechanism.
- My invention therefore consists in a machine having its parts constructed and ar ranged to carry out the aforesaid objects and sue a machine is shown, in its preferred em bodiment, in the accompanying drawings and will now be hereinafter more fully de scribed and then definitely claimed.

- 1 designates the bed or cloth plate of a sewing machine which, in the form shown in my drawings, is the ordinary twin needle overstitching machine, and there fore provided with the usual twin needles 2 and 3 which, in operation work through the two needle openings in the presser foot 5 and through the two similar openings in the throat late 9; all of which parts, except as will be ereinafter noted, may be of the ordinary construction and therefore need no further descri tion. However, it may be well to state tfiat the machine shown in my union special sewing machines and 1s fully shown in my aforesaid a plication, Serial No. 109,766.
- the aforesai throat plate 9 is made of the general character shown in my hereinbefore mentioned application, but the fixed knife 11 is detachably secured to said throat plate as shown in Figs. 2 and 3.
- Fig. 2 there is a recess 12 for the reception of the fixed knife 11 and said knife is recessed at one end, forming two lugs 14 and 16 which, when in osition, straddle the Wall 17 forming one on of the recess 12.
- the fixed knife is cut away, forming a projecting portion 19, which, when the fixed knife is in osition abuts against a portion 20 forming t e o posite end wall of the recess 12, as indicate in Fig. 3.
- the fixed knife 11 has a cuttin edge 22 quite similar to that shown in my a oresaid application except that it terminates in a needle point 23 which will readily pierce the fabric when the fabric is fed a ainst it.
- the throat plate 9 is also provide with two recesses 24 and 25 and through these recesses project the toothed ortions 27 and 28 of the feed dog 29, this og being given the usual feed movements by means of a cam 30 on a shaft 31.
- a cam 30 on a shaft 31.
- An adjusting screw is employed which has a reduced end 35 adapted to roject through an opening 37 of the kni e.
- the said screw has a shoulder 35 which presses against the foot of the knife and which may be adjusted to press the knife into a slanting position such as shown in Fig. 9 so that the pressure on the fixed knife 1S almost entirely on the cutting edge.
- this knife is loosely sup orted between the toothed portions 27 an 28 of the feed dog and is capable of lateral movement on the screw 35, it is necessary that some means he provided to hold the cutting ortion of the movable knife 33 against the ed knife 11.
- a finger 39 shown clearly in Figs. 4 and 5 and screw 46 is secured to the end of the shaft for 7 the purpose of adjusting the spring.
- screw 46 is secured to the end of the shaft for 7 the purpose of adjusting the spring.
- This mechanism is shown in Figs. 3 and 4 and comprises a finger 48 which is normally in the position shown in Fig. 4 so that it is inactive.
- This finger 48 is provided at one end with a needle point 49 and at the other end with a bent end 50 and the latter rests between the forked ends 51 of a lever 52.
- This lever is pivoted on a right angled bracket 53, which latter is slotted as shown at 54 for the purpose of guiding the bent end 50 which also projects into said slot 54.
- the finger 48 may be used advantageously in ada ting the machine to cutting varying thicknesses of fabric, that is, in addition to forcing the fabric to such a plane that it will feed over the top of the fixed cutter, it may be operated to such an extent as to ada t fabrics of varying thicknesses to be proper y fed to the point of the cutter, so as to cut one layer only.
- this movable finger By arranging this movable finger to cooperate with the fixed cutter projecting from the throat plate, it will be seen that where the piercing point is on the fixed cutter the position of said piercing oint is established, and the device or movab e finger for rendering the cutting mechanism ineffective has only to be positioned properly relative to the fixed piercing point.
- the inner edge 62 acts as a guide for the edge which passes under the point 60 and when the upper thickness of the material is fed over the point 61 and along the guide 62, it is in just the proper position to be correctly stitched for forming a collarette or other edge of a garment.
- this presser foot may be made right or left, as desired as may also the trimming attachment.
- the operator feeds two or more thicknesses of material to the machine and if it is desired to form simple necking, the fold of the material is fed under the presser foot against the needle point 23 of the fixed knife 11.
- the material is fed by the feed dogs it is fed against the fixed knife so that one thickness is underneath said knife and the other thickness is over the knife and between the knife and the presser foot.
- the under thickness is severed by the lower movable knife being rapidly moved up and down and the material is thus fed to the needles; the fixed knife at the same time deflecting the left hand severed edge from the needles while the right hand severed edge is allowed to pass between the needles.
- the deflection of one of the cut edges of the lower layer is caused by the fact that the fixed knife 33 is substantially in line with one of the needle openings, and this fixed knife is of ust the width to separate the cut edges su ciently to permit one of the needles to pass between them.
- the material passes under the needles, the overstitching 1s performed in the usual manner.
- the upper layer or layers are fed over the end 61 while the lower layer or layers pass under the said end 61 and are pressed by said end so that the lower layer or thickness will be trimmed and one edge deflected before passing to the needles.
- the up er layer or thickness which has passed over the end 61 is now assed under the end 60 and is guided by t 1e edge 62 to the needles, and as the end 61 supports the upper layer while the lower layer is being trimmed, said upper layer is fed or guided by the upturned edge 60 to the needles at a point in the rear of the piercing point 23 of the knife 11, and therefore the upper layer is not out.

SEWING AND TRIMMING MACHINE.
Specification of Letters Patent.
Patented Oct. 27, 1908.
To all whom it may concern:
Be it known that I, Gnonen Soon, a citizen of the United States of America, and resident of Amsterdam, in the count of Montgomery and State of New York, ave invented certain new and useful Improvements in Sewing and Trimming Machines, of which the following is a specification.
This invention relates to improvements in that class of sewing machines described and illustrated in my application filed May 31, 1902, Serial No. 109,756, in which a knife or cutting mechanism is combined with stitching mechanism in such a way that the fabric is cut and overstitched at one operation through the machine. The special purpose for which this machine is designed is what is known as neckin and to do this work it is necessary that tie machine be capable of feeding two or more layers of fabric, se )arating said layers, trimming one of the ayers prior to the stitchin operation and guiding or deflecting one of t fie severed edges so that it will not be sewed, and finally overstitching the undefiected severed edge to the layer or layers that have not been out. And while this machine is especially adapted for this necking it is manifest that it may be used for a number of other purposes.
The objects of the present invention are to improve the machine shown in my hereinbefore mentioned application, to simplify the parts, to rovide a movable cutter which has none of t e complicated parts shown in my said a plication; to provide a simple form of fixed nife which may be easily detached and readily replaced; to provide means for yieldingly holding one of these knives in contact with the other; to rovide a device for making the cutting device ineffective; and finally to provide a presser foot especially adapted to coact with this special form of cutting mechanism.
My invention therefore consists in a machine having its parts constructed and ar ranged to carry out the aforesaid objects and sue a machine is shown, in its preferred em bodiment, in the accompanying drawings and will now be hereinafter more fully de scribed and then definitely claimed.
In the accompanyin drawings: Fi ure 1 is a perspective view 0 a twin need e' overstitching machine, with my invention em- Fig. 2 is a perspective view bodied therein.
of the throat plate and its fixed cutter or knife, the parts being shown detached and upside down in order to better illustrate their method of attachment. Fig. 3 is a longitudinal section of the same parts in position. Fig. 4 is a vertical transverse section taken at a point to one side of the fixed cutter or knife which latter therefore does not appear in this view. Fig. 5 is a section at right anles to that shown in Fig. 4, taken on the line I X. Fig. 6 is a tperspective view of the feed dog and the kni e carried thereby. Fig. 7 is a perspective view of a spring actuated fin or which co-acts with the movable knife to old it in its proper cutting positionwith respect to the fixed knife. Fig. 8 is a ers ective view of the movable knife detac ed. *ig. 9 is a detail, on an enlarged scale, of the feed dog and knives.
Referring now to the details of the drawings by numerals: 1 designates the bed or cloth plate of a sewing machine which, in the form shown in my drawings, is the ordinary twin needle overstitching machine, and there fore provided with the usual twin needles 2 and 3 which, in operation work through the two needle openings in the presser foot 5 and through the two similar openings in the throat late 9; all of which parts, except as will be ereinafter noted, may be of the ordinary construction and therefore need no further descri tion. However, it may be well to state tfiat the machine shown in my union special sewing machines and 1s fully shown in my aforesaid a plication, Serial No. 109,766. The aforesai throat plate 9 is made of the general character shown in my hereinbefore mentioned application, but the fixed knife 11 is detachably secured to said throat plate as shown in Figs. 2 and 3. As shown In Fig. 2 there is a recess 12 for the reception of the fixed knife 11 and said knife is recessed at one end, forming two lugs 14 and 16 which, when in osition, straddle the Wall 17 forming one on of the recess 12. At the opposite end the fixed knife is cut away, forming a projecting portion 19, which, when the fixed knife is in osition abuts against a portion 20 forming t e o posite end wall of the recess 12, as indicate in Fig. 3. It will thus be seen that when the fixed knife 11 is placed in position by inserting the two lugs 14 and 16 in the recess 12, so that said lugs drawings is one of the well known types of I are on opposite sides of the end wall, the projecting portion 19 then fits against the end wall 20 of the throat plate, and when said throat plate rests on the supporting bed plate 1, as indicated in Fig. 3, t e fixed knife is securely held in position. At the same time, whenever it becomes necessary to remove said fixed knife in order that it may be sharpened, or that a new one may be placed in position, it is merely necessary to remove the throat late 9 when the fixed knife can be taken out y the reverse recess of that just described. Of course, t e parts shown in Fig. 2 are shown with the throat plate turned upside down in order to give a better idea of the method of placing these parts together. The fixed knife 11 has a cuttin edge 22 quite similar to that shown in my a oresaid application except that it terminates in a needle point 23 which will readily pierce the fabric when the fabric is fed a ainst it. The throat plate 9 is also provide with two recesses 24 and 25 and through these recesses project the toothed ortions 27 and 28 of the feed dog 29, this og being given the usual feed movements by means of a cam 30 on a shaft 31. As these parts are old, it is not necessary to further describe them except to state that the shape of the cam is such that during the movement from right to left, as the parts are shown in Fig. 4, the toothed portions 27 and 28 of the feed dogs receive an upward as well as a forward movement. This double movement is the very movement necessary for a cutting edge, and I therefore make use of the feed dogs to support my movable knife 33 which, as indicated in Figs. 5 and 6, ro'ects up through the throat plate against t e ed knife 11. By an examination of Figs. 5 and 6 it will be seen that there is quite a large recess between the two feed dogs, and the movable knife 33 is situated between said dogs; the said knife having a foot 36 passin into a recess 28 in the web connecting t e feed dogs. This movable knife is shown detached in perspective view in Fig. 8 and when placed in position the foot 36 is placed down between the toothed ortions of the feed dogs 27 and 28. An adjusting screw is employed which has a reduced end 35 adapted to roject through an opening 37 of the kni e. The said screw has a shoulder 35 which presses against the foot of the knife and which may be adjusted to press the knife into a slanting position such as shown in Fig. 9 so that the pressure on the fixed knife 1S almost entirely on the cutting edge. Inasmuch as this knife is loosely sup orted between the toothed portions 27 an 28 of the feed dog and is capable of lateral movement on the screw 35, it is necessary that some means he provided to hold the cutting ortion of the movable knife 33 against the ed knife 11. To perform this service, I employ a finger 39, shown clearly in Figs. 4 and 5 and screw 46 is secured to the end of the shaft for 7 the purpose of adjusting the spring. By reference to the drawin s it will be seen that when the barrel 41 and its connected arts are in position, the finger 39 will be hefil by the spring 45 up against the movable knife 33 so as to hold the upper cutting edge of said knife in close contact with the fixed knife 11. Of course the spring is adjusted by the thumb screw 46 until its tension is just sufficient to hold the finger 39 against the movable knife 33 and yet permit said knife to move up and down between the fixed knife 11 and said finger 39.
It is sometimes necessary to sew a garment and trim one portion and not another portion; it is also sometimes desirable to sew a garment without making use of the trimming mechanism; and in order to permit either of these operations, I provide a device which is designed to make it possible to render the trimming mechanism ineffective. This mechanism is shown in Figs. 3 and 4 and comprises a finger 48 which is normally in the position shown in Fig. 4 so that it is inactive. This finger 48 is provided at one end with a needle point 49 and at the other end with a bent end 50 and the latter rests between the forked ends 51 of a lever 52. This lever is pivoted on a right angled bracket 53, which latter is slotted as shown at 54 for the purpose of guiding the bent end 50 which also projects into said slot 54. The construction of the parts is such that when the lever 52 is moved in the direction of the arrow in Fig. 4, the pointed end 49 of the finger 48 is projected u into the position shown in Fig. 3 so that t is point 49 is on the same lane with the ointed end 23 of the fixed ife 11. It wi 1 therefore be manifest that when the operator desires, the lever 52 may be moved so as to project the finger 48 in front of the fixed knife, and thus prevent the point 23 of the latter from penetrating the fabric. It will also be obvious that by reason of this construction, inasmuch as the finger 48 bears upon the under side of the fabric, it may be used advantageously in ada ting the machine to cutting varying thicknesses of fabric, that is, in addition to forcing the fabric to such a plane that it will feed over the top of the fixed cutter, it may be operated to such an extent as to ada t fabrics of varying thicknesses to be proper y fed to the point of the cutter, so as to cut one layer only. By arranging this movable finger to cooperate with the fixed cutter projecting from the throat plate, it will be seen that where the piercing point is on the fixed cutter the position of said piercing oint is established, and the device or movab e finger for rendering the cutting mechanism ineffective has only to be positioned properly relative to the fixed piercing point.
I do not herein claim broadly a work support, combined with a feeding mechanism, and a cutting mechanism with means operat ing upon the material for diverting the material with respect to the cutting mechanism, whereby varying thicknesses of goods may be cut, or the cutting action renderedineflective. I have also designed a special form of presser foot which is adapted for work with the particular cutting mechanism shown in my drawings; this presser foot being provided with two projecting ends 60 and 61 with an opening between them. One of these projecting ends 60 is bent upward as indicated in Fig. 1 and the construction is such that when two or more thicknesses of material are fed to the machine, one of themthe one that is to be trimmedis fed under the end 61, while the thickness not to be trimmed is passed over the end 61 and is caught under the upturned end 60 and thus fed to the needles at a point where it will be fed over the upper edge of the fixed knife 11 and will therefore not be cut. The inner edge 62 acts as a guide for the edge which passes under the point 60 and when the upper thickness of the material is fed over the point 61 and along the guide 62, it is in just the proper position to be correctly stitched for forming a collarette or other edge of a garment. Of course this presser foot may be made right or left, as desired as may also the trimming attachment.
In operation the operator feeds two or more thicknesses of material to the machine and if it is desired to form simple necking, the fold of the material is fed under the presser foot against the needle point 23 of the fixed knife 11. As the material is fed by the feed dogs it is fed against the fixed knife so that one thickness is underneath said knife and the other thickness is over the knife and between the knife and the presser foot. As the material continues to be fed, the under thickness is severed by the lower movable knife being rapidly moved up and down and the material is thus fed to the needles; the fixed knife at the same time deflecting the left hand severed edge from the needles while the right hand severed edge is allowed to pass between the needles. The deflection of one of the cut edges of the lower layer is caused by the fact that the fixed knife 33 is substantially in line with one of the needle openings, and this fixed knife is of ust the width to separate the cut edges su ciently to permit one of the needles to pass between them. As
the material passes under the needles, the overstitching 1s performed in the usual manner. When it is desired to attach collarettes or similar articles to garments, the upper layer or layers are fed over the end 61 while the lower layer or layers pass under the said end 61 and are pressed by said end so that the lower layer or thickness will be trimmed and one edge deflected before passing to the needles. The up er layer or thickness which has passed over the end 61 is now assed under the end 60 and is guided by t 1e edge 62 to the needles, and as the end 61 supports the upper layer while the lower layer is being trimmed, said upper layer is fed or guided by the upturned edge 60 to the needles at a point in the rear of the piercing point 23 of the knife 11, and therefore the upper layer is not out.
It is obvious that changes and modifications may be made in my invention without departing from the spirit thereof. As a mere example, it is obvious that my invention may be applied to a single needle machine or to a five thread machine, or in fact to any character of machine with which it will properly coact. It may also be noted that in some of my claims I refer to a movable cutter and to a fixed cutter; and these terms are used with relation to each other and I do not mean to imply that the fixed knife is necessarily inte rally secured to its support but is merely fixe relatively to the movements of the movable knife. Other modifications will be manifest, and I therefore refer to the following claims to set forth the scope of my invention.
