PORTABLE SEWING DEVICE.

Specification of Letters Patent.

Patented Jan. 11, 1921.

Application filed May 28, 1920. Serial No. 384.839.-

T 0 all whom it may concern.

Be it known that I, PAUL KAN'roR, a citi- Z611 of Poland, residing at Sonman, in the county of Cambria and State of Pennsylvania, have invented certain new and useful Improvements in Portable Sewing Devices, of which the following is a specification.

The present invention relates to a portable sewing device in the form of a hand implement that is especially designed for sewing leather, such as shoe soles and has for its primary object toprovide a novel form of needle combined -'with a spool holder.

A further object of the invention is to provide in a leather sewing device adapted for the mendin of shoes an 1m rov'ed construction of sewing needle formed of relatively movable parts to facilitate the positioning of the sewing thread in the eye thereof.

With the above and other objects in view, the present invention consists in the novel form, combination and arrangement of parts hereinafter more fully described and shown in the accompanying drawing, wherein like reference characters indicate similar parts throughout the several views.

In the drawing,

Figure 1 is a side. elevational view of a hand sewing implement constructed in accordance with the present'invention,

Fig. 2 is a vertical sectional view taken through the needle holding part and the thread spool holding part, showing the manner of depressing the shiftable needle section and supporting thethread spool,

Fig. 3 is a vertical sectional view taken through the needle supporting casing showing the tensioned rod and handle for shifting the movable needle section,

Fig. 41 is a side elevational view, partly in section of the needle removed from the casing, and showing the movable section of the needle by dotted lines in shifted position,

Fig. 5 is a cross sectional view taken on line V-V of Fig. 4: showing the two needle sections, and

Figs. 6 and 7 are fragmentary sectional views of leather strips connected together by difierent forms of stitching with the present device.

Referring more in detail to the accompanying drawing, there is illustrated a hand leather sewing implement embodying a needle 1 carried by a casing 2 while thread upon a spool is rotatably supported within a casing 3 connected to the casing 2 by the arm 4-.

The needle 1 is shown in detail in Fig. 4 asembodying a head portion 5 formed with a mounting threaded plug 6 and carrying an integral needle section 7, the lower end 7 of which forms one wall of the needle eye, thewall 7 terminating as at '7" at a point spaced inwardly of the outer end of the needle eye. A shiftable needle section 8 is slidably associated with the rigid needle section 7 and embodies a stem 9 slidably projecting through a longitudinal opening in the needle head 5 as shown in Fig. at with'a head 10 upon the upper end of the stem that is engaged by one end of a spring 11 surrounding the stem and engaging at its other end'the head 5. The shoulder 12 at the base of the stem 9 engages the wall 5 of the needle head 5 to' limit the upward movement of the needle section 8 as influenced by the spring 11. The inner end of the needle section 8 is pointed as at 13 to provide the entering end of the needle while the wall 8 of the needle section 8 cooperates with the wall 7 to form the eyeopening of the needle.

The. construction of casing 2 is more clearly shown in Figs. 2 and 3 as embody ing an upper cylindrical portion 14; closed at its upper end by a screw cap 15 while the inner wall of the lower end thereof is cylindrically formed and screw threaded as at 17 for the reception of the screw threaded plug 6 of the needlehead 5. A partition wall 18 is transverselypositioned in the casing 1 1 at the point of connection with the lower tapered end 16 and carries a vertical tubular bearing 19 terminating at its upper end at a point spaced inwardly of the cap 15. A rod 20 is slidably positioned in the tubular bearing 19 and is provided with a head 21 upon the upper end thereof for engagement by one end of a coil spring 22 which surrounds the rod 20 and engages at its other end, the upper end of the tubular bearing 19. As shown more clearly in Figs. 1 and 3, the side wall of the casing 2 is slotted as at 23 for the passage of the operating handle 24 of the arm 25 that is connected to the head 21 upon the rod 20.

The thread holding casing 3 is of the form illustrated in Figs. 1 and 2 and is open at each end' thereof as shown in Fig. 2 while the upper end receives a disk carried by the resiliently mounted arm 26 swingingly mounted upon the casing 3. A thread spool and holder are mounted in the casing 3, the thread spool 27 being received in the open outer end of the tubular holder 28 and retained therein by the tensioned arm 26 engaging the outer end of the spool. The inner end of the holder 28 has one face thereof tapered as at 29 to provide a pointed end 30 while the lower end of the casing 3 is cut away as at 3 to provide a limiting engaging wall for the holder 28.

One Wall of the holder 28 is slotted as at 31 for the passage of the thread 32 delivered from the spool 27. The thread 82 may be passed through the eye in the needle 1 and the implement is then ready for a sewing operation. Two forms of stitching are shown in Figs. 6 and 7 that it is possible to produce with the present implement and the type of stitching shown in Fig. 6 will be first described. Separate leather strips or other material -a and b are united by the thread 32. A comparatively long strand of thread 32 is withdrawn from the spool 27 and the pointed end 30 of the spool carrier 28 is adapted for piercing the leather strips a and b and the needle 1 is then forced through the opening made thereby. With the eye of the needle projecting from the opposite side of the strips a-- and b, the handle 24 is shifted in the slot 23 to move the rod 20 against the tension of the spring 22 with the lower end of the rod engaging the head 10 of the needle stem 9 to move the end 13 and 8' of the needle section 8 relative to the needle section 7 and eye portion 7, thus to open the eye to facilitate the introduction of the thread therein. lVhen the thread is within the eye opening, pressure on the handle 2-1 is relieved and the springs 11 and 22 permit a closing movement of the eye sections, at which time the needle is withdrawn through the material and carries therewith the thread 32. The

free end of the thread is completely drawn through the material and the needle 1 is then inserted through the material from the opposite side thereof to have the thread introduced into the needle eye in a manner as above described and again withdrawn. This operation is continued until the desired length of stitching is completed and it is to be understood that the pointed end 30 ofthe spool carrier 28 may be employed in a manner as will be obvious for correctly spacing the stitches and also to facilitate the passage of the needle 1.

In the form of stitch shown in Fig. 7, the needle 1 is inserted through the leather strips a and b in the direction indicated by the arrow c-- and the thread 33 is passed through the loops 32 formed in the thread 32, the needle 1 having the thread continuously positioned in the eye portion thereof at all times and forming a loop portion 32' upon the side of the strip a.

From the above detailed description of the invention, it is believed that the construction and operation thereof will be apparent and while there is herein shown and described the preferred embodiment of the invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the same as hereinafter claimed.

WVhat is claimed as new is:

A sewing device of the character described comprising a casing, a needle embodying a threaded plug removably carried by the lower end of the casing, said needle being formed of movable and rigid parts, the movable part including a tensioned stem, a tensioned rod manually shiftable within the casing and in engagement with said stem for shifting the movable part of the needle against the tension thereof.

In testimony whereof I affix my signature.

PAUL KANTOR.
