STITCHING DEVICE 3 SheetsSheet 2 2? 1i. I 2 26 2 m INVENTOR. 599F455 J. Mad/.5
Patented July 3, 1951 UNITED STATES PATENT OFFICE 13 Claims.
My invention'relates to hand-operated stitching devices of the character embodied in my Patent No. 2,091,828, issued August 31, 1937, and it has for a purpose to structurally and functionally simplify such devices, so as to reduce the manufacturing cost thereof, and the number of manual manipulations necessary to form stitches thereby making it more practical in use than prior devices.
It is also a purpose of my invention to provide a stitching device which embodies a thread looper and which utilizes the conventional sewing machine needle formed along one side with a groove for receiving a length of thread from which the stitches are formed, and in such manner that a ength of the thread at the other side of the needle, is caused by the looper to produce a loop which can be grasp-ed by the finger of the operator to allow the needle to be extended therethrough and then through the cloth or other fabric in the formation of a loop or chain stitch as in basting, felling or the like.
I will describe only two forms of stitching devices each embodying my invention, and will then point out the novel features thereof in claims.
In the accompanying drawings:
Fig. 1 is a view showing in side elevation one form of stitching device embodying my invention.
Fig. 2 is a top plan view of the device.

Fig. 11 is a view similar to Fig. 10, showing with theneedle retracted from the cloth and ready for advancement to extend the needle throughthe thread loop.
Fig. 12 is a viewsimilar to Fig. 11, showing the needle extended through the thread loop and" through the cloth to complete one cycle of'operation in the formation of one stitch, and with the users digit again in position to start the formation of another stitch;
Fig. 13 is a'view'showing in side elevation and" partly in section, another form of stitching device embodying my invention and showing the thread looper thereof in advanced position.
Fig. 14 is a view similar to Fig. 13 showingthe' and a rear head I6 bridged by an upper strip I! and a lower strip 18, with the strips spanned at one side of the frameby a wall 20 curved toac commodate a spool 2| of thread 22 between the heads which is'insertabl intothe frame through the open side 23 thereof. The spool'is rotatable on a spindle 24 which is extended axially through the rear head l6 and into the front head I5 where it is removably secured by a frictional fit.
Projecting centrally forward from the head-l5 and preferably integral therewith; is an extension 25 for supporting a needle 26 and providing a mounting for a thread looper generally indicated at 27. The extension 25 may have a'downwardly inclined upper edge 28 to give a tapered form to the extension so that it can be readily held between the thumb and index finger of the user, and a recess 29 at its lower right hand corner to accommodate and permit movement of certain parts of the looper 21;
The needle 26 is of the conventional type used in sewing machines, in that it has a non-circular shank 30 at one end extending into a suitable socket 3| in the forward end of the extension'25, and secured therein by a set screw 32'threaded in the extension. The leading end of the needle is pointed as at 33, while adjacent the pointed end an eye 34 is formed'in the needle. As shown'best in Figures 2 and 3, the shaft of the needle along one side and leading rearwardly from theeye, is
formed with a groove 35 of sufficient depth to accommodatea portion of the thread 22, as will be more fully described hereinafter.
The thread looper 21 of my device broadly consists of a head 31 straddling the needle '26, and
movable in either direction therealong to occupy, at the leading end of the extension 25, an advanced position as shown in Fig. l or a retracted position as shown in Fig. 5; a supporting and guiding member 38 forthe head 37; and spring means 39 for urging the head to advanced position.
In the present instance, the forward upstanding end of a U-shaped yoke 40 is employed as the head 31, while the member 33 comprises a rod passing through the extension 25, across the recess 29 and into the front head I5 where it is secured by a frictional fit. The spring means 39 comprises a coiled expansible spring received in a pocket 4| in the forward end of the extension 25, surrounding the rod 38, and bearing against the head 37 to urge it to the advanced position to which it is definitely limited by the rear vertical portion 42 of the yoke. This yoke portion 4'2 is slidable on the rod 38 to abut the forward wall of the recess 29, and thus define the advanced position of the head 31, while the rear wall thereof defines the retracted position of the head.
The thread 22 on the spool is extended therefrom into a slot in the lower strip IS the forward and rearward ends of which are indicated at 43 and. 44, and forwardly along a groove 45 to and along a groove 45 (see Fig. 8). From the latter groove the thread extends along the grooved side of the needle and finally through the eye 34 to the other side of the needle. That the thread may follow the course described the grooves 45 and 46 must be of a depth corresponding to the level of the needle as held in the extension 25, and the bottom and end portions of the yoke must be slotted as at 41. The slotting of the head 31 accommodates the needle 26, and thus the head straddles the needle (see Fig.3).
In describing the operation of my device reference will be had to Figs. 9 to 12. With the frame F held in one hand of the user so that the thumb and forefinger can grasp opposite sides of the extension 25, the needle and thread are extended through the cloth K, as shown in Fig. 9, with the thumb or forefiinger of the other hand, depending upon whether the cloth is held in the other hand or laid fiat on a table, held on the cloth beneath the needle point to act as an abutment. Thus as the needle is passed through the cloth, and the thumb held against movement, the cloth is caused to fold upwardly as at KI, and against the head 31, and by continued forward movement of the needle the head is moved rearwardly along the needle to retracted position thereby compressing the spring 39. During such movement of the head 31, the length of thread 22a at the grooved side of the needle is drawn into the groove, while the length of thread 22b at the other side of the needle is drawn rearwardly through the fold and against the needle, and, in consequence, the thread is fed from the spool 2| through the needle eye.
The next step in the operation of the device is shown in Fig. '10, wherein the digit is lifted from the cloth relieving the head 31 of any rearward pressure, thus allowing the spring 35 to expand and thrust the head and the cloth fold Kl forwardly along the needle. Since the thread length 22a is within the groove 35 it will not I be drawn forwardly as the cloth is thrust forwardly, but will remain extended along the needle. However, the thread length 22b under the forward thrust of the cloth will be drawn forwardly to form a loop 220 between the cloth fold KI and the needle eye, and at the same side of the needle and flat against the cloth.
This operation is immediately followed by the user placing his digit on and holding the loop 220 against the cloth, while the needle is withdrawn from the cloth as shown in Fig. 11 to be extended through the loop and then through the cloth as shown in Fig. 12, thereby completing the formation of one loop stitch. Incident to this last operation, the digit is removed from the loop and replaced on the cloth in advance of the needle so as to cause the cloth to fold under forward movement of the needle and thus cause the latter to pass the thread through the cloth leaving the parts of the device in position for the formation of a second stitch.
From the foregoing mode of operation of my device, it is manifest that to form loop or chain stitches requires only simple manipulations of the device performable by even the layman, and thus rendering the device extremely practical for the skilled as well as the unskilled user.
Fig. 6 illustrates how the device may be used where the source of thread supply is not contained on the spool as carried in the frame, but at some point remote from the device. In this case the thread is extended from the supply source through an opening 48 in the rear head l6, whence it passes downwardly to the slot 43, and then to the needle in the same manner as from the spool.
Referring now to Figs. 13 to 15 I have here shown another form of stitching device embodying my invention which, while operable by the user in the same manner as described and illustrated in connection with the first form of my device, is structurally simplified to reduce its cost of manufacture and facilitate handling and manipulation.
The instant device comprises a frame Fl of triangular form and having finger receiving grooves 50 in its opposite sides so that in use it may be gripped at these points. The source of thread supply is not carried by the frame but is remote therefrom, the thread 22 being extended through an opening 5| in a lip 52 on the small end of the frame, and then laterally into a groove 53 in one side of the frame. From the groove the thread is extended again laterally into and along the groove of the needle 26 and finally through the eye 34.
The needle shank 35 is secured by a countersunk set screw 32a in a socket 3|a in the frame so that the needle proper projects from the forward or wide end of the frame at the lower corner thereof.
The thread looper indicated at 21a comprises an arm 55 having an ear 55 on its upper end positioned between a pair of ears 56 formed on the frame Fl by slotting its upper corner. Through all three ears extends a pin 5'! to form a pivot for the ear 55 and thus pivotally support the arm 54 on the frame.
A coiled expansible spring 58 is fitted in a recess 59 in the frame to bear against the inner side of the arm 54 and thus urge the latter to the extended position shown in Fig. 13, and which position is defined by the upper end 54a of the arm abutting the corner of the frame Fl.
As best shown in Fig. 15, the arm 54 is formed with an inclined slot 59 leading inwardly from one vertical edge of the arm and upwardly to the upper end of a vertical slot 56. The lower end of the slot 59 communicates with an opening 6| through which the needle extends, and this asaas'fs opening is vertically elongated to allow of movement of the arm 5 5 without striking the needle.
The slots 59 and as and the opening Si afford means by which the thread 22 from the groove 53 can be extended to and through the eye 3 of the needle, and held within the needle groove 35 during use of the device.
The use of my device can be readily understood from the description of the use of my first device, as it is apparent that the looper arm 54 is moved to occupy the retracted position shown in Fig. 14. as does the looper head 37 in the first device, when the needle 26 is advanced through the cloth with the thumb held in the position shown in Fig. 9. Conversely, when the cloth is released and the arm 54 relieved of rearward pressure, it will under the action of the spring 58, be advanced along the needle to form the thread loop 220 (Fig. 10).
Although I have herein shown and described only two forms of stitching devices each embodying my invention, it is to be understood that various changes and modifications may be made therein Without departing from the spirit of my invention and the spirit and scope of the appended claims.

A stitching device, including: a frame having an extension at one end thereof of substantially L.-form; means in said frame supporting a spool of thread therein for free rotation about an axis longitudinally of the frame; a needle fixed in and projecting from one end of said extension, said needle having an eye adjacent its pointed end, and a groove longitudinally in one side thereof; coacting means in said frame and. said extension for guiding the thread from said spool along said frame and extension to parallel the grooved side of said needle; a rod extending through and fixed in said extension; a pocket in said extension; a U-shaped yoke having the parallel portions thereof slideable on said rod at opposite sides of said extension so that one parallel portion is movable along said needle, said portion having an opening therein so that it straddles needle; and a spring in said pocket and around said rod to engage said yoke portion for urging the yoke forwardly on said needle.
8. A stitching device, including: a thread supporting frame; a needle fixed in said frame, said needle having a groove in one side thereof in which the thread from which the stitches are formed is adapted to be received, and an eye adjacent the point thereof through which the thread from said groove is extended to the other side of the needle; a thread looper pivotally mounted on said frame; and means for yieldably urging said looper to an advanced position in relation to said needle wherein it is intermediate the ends thereof, said looper being manually swingable on said support against the action of said urging means from the advanced position to a retracted position toward the proximal end of the needle as the latter is extended through the fabric being stitched, so as to pull the thread rearwardly on the needle and provide an extended thread length at that side of the needle opposite the grooved side, whereby upon releasing said looper said urging means will return it to advanced position causing the thread length to form a loop at one side of the needle.
9. A stitching device, including: a thread supporting frame; a needle fixed in said frame, said needle having a groove in one side thereof in which the thread from which the stitches are formed is adapted to be received, and an eye adjacent the point thereof through which the thread from said groove is extended to the other side of the needle; a thread looper including an arm pivoted on said frame and having a portion surrounding said needle; and a spring between said arm and said frame for urging the arm to a forward position on said needle.
10. A stitching device, including: a frame of substantially triangular form; means for holding a needle projecting from the wide end of said frame at one corner thereof; and a thread looper comprising an arm pivoted on said frame at a second corner of said frame, said arm having an opening in its free end through which the needle extends, and a spring for urging said arm outwardly from said frame so that the free end thereof occupies an advanced position along the needle.
11. A stitching device, including: a thread supporting body; a spool of thread mounted for free rotation in said body; a needle extended from said body, said needle having an eye adjacent the point thereof and a groove in one side extended from said point toward said body and adapted to receive a thread extended from said spool in said body to and through said eye, a thread looper movably mounted on said body for movement longitudinally of said needle and including a fabric-contacting head extended transversely of said needle and adjacent thereto, spring means yieldably urging said looper to a foremost advanced position in relation to said needle wherein said head is intermediate the ends thereof, said looper being manually movable on said support against the action of said spring means to move said head from the advanced position to a retracted position toward the end of said needle spaced from said eye as the latter is advanced through a fabric being stitched, said spring means being sufiiciently strong to return said looper to said advanced position, said looper head forcing the pierced fabric along said needle and toward said eye as said looper returns to said advanced position whereupon a thread length along said needle exterior of said needle groove will be formed into a loop forward of the fabric.
12. A stitching device, including: a frame having ahead, a rigid thread-guiding member projecting longitudinally from one side of the head, and an extension projecting from the other side of the head; a spindle fixed to the head at the same side thereof as the member and parallel to and spaced from the latter so that a, spool ofthread can be rotatably mounted thereon; meanson the extension for securing the butt end of" a sewing machine needle therein with the needle extending longitudinally of and from the free end of the extension; the member and the extension having grooves lengthwise therein through which the thread from a spool on the prising a head, a rigid thread-guiding memberprojecting longitudinally substantially at rightangles from one side of the head, and an exten-' sion projecting substantially at right angles from the other side of the head and having apart thereof longitudinally alined with the member; a spindle fixed at one end to the same side of the head from which the member projects and disposed substantially in parallelism with the member; a spool of thread rotatably mounted on the spindle to feed thread under a force exerted through the thread alone during the formation of the successive stitches; and a needle fixed in and projecting longitudinally from the free end of the extension, the needle having a groove longitudinally therein, and an eye adjacent the point thereof, the extension and the member having longitudinally alined grooves therein, and the member having a slot leading to the groove therein, whereby the thread from said spool can be extended through the slot, then in and along the member, extension and needle grooves, and finally through the needle eye and a looper movably supported by the extension.
