To all fwwm 'it may concern.'

Be it known that I, FRANK Bussinnn, a citizen of the United States of America. re- -siding at Essexville, in the county of Bay 'and State of Michigan, have invented certaininew and useful Improvements in Sewing Machines, of which the following is a.

specification. i

This nivention relates to improvement-sin hand operated sewmg machines and the like.

One object of the invention is to provide y a hand operated sewing machine ofa size which can be conveniently carried in the pocket, or packed in a traveling bag.

`A further object is to design a sewing ma! chine forquickly mending rents in vclothing or the like when traveling, or in the field.

A still further object is to design a hand operated sewing machine by means of which tents, blankets or othenl articles requiring considerable sewing can vbe quickly sewed, eliminating the use of' the vhand operated needle and thread, and without bringing the material to the usual sewing machine generally used for such purposes.

With the above and other objects inview, the present. invention consistsl in the combination and arrangement of the diiierent parts, hereinafter more fully described, illustrated in the accompanying drawings,

and more particularly pointed out in the appended claims, it being understood that changes may be made inthe form, size, and proportion of the ydierent parts without rdeparting from the spirit ofsacriicing any of *the advantages of the invention.

Figure 13 is a detail showing the position parts of the thread in they needle when has .pierced the cloth. v

Figure 14 isa detail showing'the loopr y formed by theithread whenne'edleis intheposition shown in dottedlines in Fig, .12'.l

F1gure15 is an enlarged view illustratint'g"v the stitches on the underside or" the cl` oth,'thej needle being shown 'in section.y I Referring now' more particularly to drawings in vwhich Ihavedesignated `the outer casing of the machine by thev numeral f 1, the upper portion of which is adapted to f be closed means of a `cover 2,- hinge'd thereto in anyfsuitablewnianner izo-allowthe7 spool of thread'to be inserted in the ':as"e,tln`ev tending therethroughvin a `'rnann'erto be hereinafter more fully described. I i l ,7c :bottom of the case-is open, a pressurebareir- Secured tothe interior of the case member- 1 is a plate 3, this plate being=bcnt as shown in Figuresf and 6 to form `a closure l for the bottom of the case, itis further Vprovidedwith an opening 1,'th'rou'gh whichthe Y f pressure bary 5 is adaptedto extend, la smallf1A pinion member 6 being mounted on' la rshaft member 6a whichv is journaledlto the plate 3, Ia crank member 7 is also .rigidly seated on' this shaft 6 one end .thereof beingpivoted to the connecting link Skat the point 9; ther l Y .90

opposite-end of the link. being in turn piv-l oted to, across head 11 at the point 12,-5the. ,.crosshead being grooved as shown at 12,.in

Fig. 9,.to lit the edges :of the plate member 3,.

'which is formed to-receive saine, .'anfordi.- .naryeewing machmeneedle is Inserted. in the. f opening 1n the cross head 11, and is securedv 1n position bvmeans offza, small'setscrew f An operating handle 15' is pivoted theA plate 3 at the point A16, the forked. portion 15a extending beyond the case and is designed to fit the fingers of the operator. The inwardly extending,` ortion is formed with a plurality of teethl on the inner-.surl face thereof which are adapted to mesh with i. the pinion 6,v a coiled spring member 18 be.

ing secured to the handleand to the plate,

and it will be obvious that as .the operatingl handle vis forced to the position shown in dotted lines i'n Fig. 5, that the pinion 6 will be'rotated and the connecting rod and crank will assume the position shown in dotted lines, the spring will be stretched, and the`Y vshown at 2O and extends through the wallsv of the case to torm a thumb rest, the bar extends downwardly'being bent as shown at the point 21, and having a coiled rexpansion spring 22 interposed between the bar and the plate member, thence the, bar extends belw the bottom of the case, thence up and having 'a flat portion 23 over which the cloth or'material to be sewed is adapted to feed,.the ends of the said ilatted portion bein bent downwardly so that they will not caich i'n.l the clothor other material.

A pfin'ion member 24 is mounted on the shaft 25, one end being jou'rnaled in the wall of the plate, the opposite end being journaled in the upwardly bent lug 26, a suitthe face Vof the pressurebar.

able opening being provided in thledplate .3 through which said pinion is adapte to extend for forcing the cloth or materialacross 'i The pinion member 24 is adapted to ibe 'rotated by means of a spring tensioned ratchet arm 27', slidably secured to the plate 3 by means ofthe member 29, extendingthrough -the slotted opening28, the upper end of the said arm'extending inwardly and into the path vofthe cross head 11, a spring member 30 being anchored to the said ratchet armand to the plate member 3, and it will be obvious that as the .cross head os cillates upand down'it will strikethe inwardly extending'portion of the said arm 27 on its upward stroke, raising the said arm and rotating the pinion member 24:A for feeding the cloth or material across the face of the pressure barthe spring member 30 'drawing the ratchet' bar down for again en gaging the teeth'of the pinion. l' c The length of -stitch is regulated by Vmeans ofthe'cam lever 31' pivoted to the 'plate 3 at the point 32, the lower end of'said lever being bent outwardly and extends through a' suitable opening provided in the case 1, so that' the said lever can be readily operated, the upper end of this lever is cam shaped and by turning the; said lever it will be readily understood that the length of neonata travel of the said ratchet arm and consequently the travel of the material across the face of the pressure bar `can be accurately refulated.

Il wish to call particular attention to the fact that 'the ordinary sized s ool of thread can be employed theY spind en being indicated by the numeral 33, and clearly shown in Fig/4 of the drawings, and in the resent instance I have shown this spindle formed of one piece o'f material, theends 34 being pivoted in the walls of the case, Athe spindle being swung upwardly', and the spool placed ,in position, the spindle is then swung down to horizontal position, the end thereof entering a slot'in the end of the case, the thread extends through a slotted opening 35 beneath the lip of the cover, thence in'under the portions 36 formed on the case, and between the members 14, thence being threaded into the needle 37.-

The machine is desi ed for so called' single stitching, and in,I igures 1U to 14 I show the dilferent positions of the Ythread and they several parts,vFigure 10' illustrates the needle in lraised position, the ratchet having rotated thevpinion for moving the ,y

cloth or material 38 across the face of the pressure bar, Figure 11 illustrates the position of the needle when'the stroke is one half completed, with the ratchet in lower position for againl engaging the teethl of pinion 24, Figure 12 is a view showing in dotted lines the stroke three quarters completed 'and in solid lines, the position at the end of the stroke, and Figure 13 shows the position of the thread when the needle has pierced the cloth; Figure 14, illustrates the thread vlooped when the needle is' withf drawn, while Figure 15 is an enlarged view of the' stitches, and it will be obvious that the position of the cam lever determines the length of the stitches by regulating the movement of the ratchet member 27 which rotates the pinion forfe'eding thecloth over the face of the` pressure bar.

' I further wish to call vattention to the groove 38 .which is formed in the bottom. of the plate 3 directly in line with'the opening 39through which the kneedle travels,

and when the needle travels the ratchet member rotates lthe pinion 24 pulling the clothforward, the thread forming a loop as shown in Figure 14, and when the needle is in the position as shown in dotted lines in Figure 12, the loop is drawn Hat against the pressure bar in under the cloth, and the thread from the eye of the needle will bey drawn along the groove 38 and it will have no frictional resistance, but the upward pull of the spring 22 lon the pressure b'ar will maintain a frictional resistance on the loop below the cloth, so'that all slack inthe thread will be taken up in each succeeding stitch, the downward movementI of the needle passes through this loopV and oompletes thesingle stitch shown in Figure 15.

For placing the material to be sewed in proper position it is merely necessary for the operator to press downwardly on the portion 20 of the pressure bar thereby forcing the face of the pressure bar away from the pinion 24 a distance sufficient to allow the cloth to Ybe placed in position, the body of the case is then placed in position in the palm of the hand, and the fingers engage the handle 15 for operating the machine.

From the foregoing description it will be obvious that I have perfected a simple and economical sewing machine which can be conveniently carried in the pockets of the operators garments. t f
