Tri all whom L may concern: v

Be it known that I', HELEN A. BLANeHARma citizen of the United States, residingat Philadelphia, in'

the county of Philadelphia and State of Pennsylvdnia, have invented new and useful 'Improvementsin Hat- Sewing Machines, of which the following is a specification.A

My invention relates to certain new and useful improveniente in sewing machines making a common overedge' chain stitch with one thread a plurality of thread carriers; and it is designed primarily to sew sweat-bands into hats and onto astrap of linenor other material, hereinafter termed a reed, which hasI been i previously hzisted onthe inner edge of the h'at.

' toher 1901, ythe nischine'sewng reducing the cost oi i lthe finished hat and resulting in a betterl fastening of Hcretofrethe sweatbands in hats have been sewed onto the busted strip by hand, and by, machinery, as ior instance by the mechanismvshown, described sind claimed in my former patent No. dfdf'dated Octhe sweat-band to the basted strip of the hat. i The present invention-is an improvement on my aforesaid prior patent and it .omprehends means `for supporting the hatwith its' attached or hosted reed relative to the band and then'attaching the sweat hand 'or leather to the eedby a sewing 'thread and a.

locking filament or thread, v vhichisA automatically fedY with the band, and which is mbved alternately substentially across the pitth described by the lower sewing needle, and eoncatenating the sewing thread to form a series of interlocking loops certain of which are looped around the locking filament or thread and others ockefl outoi sight in the seperate thread and thereby removed iroln the edge of the reed'.

M y invention further comprehends certain improvements in' the means by which a lockingthreador fils.- rnent is movedlsubstantially into and out of the range oi action of one of the sewing needles; in the means for actuating an oscillat'ng thread carrier or looper; in

the arm of 'the machin having a jointed or hinged section Iand locking means therefor, and in certain other fer-.turcs which I'ywill hereinafter describe and claim.

In kthe accompanying drawing, l illustrate a machine o the type shown in my said former patent, having the present improvements eppliedy thereto.

Figure 1 isaside elevation oi the sewing machine, I

Fig. fi is a similar" section ou the linee-4 of Fig. l. lFighis s .wcijoss-sec'tion on', y the line otli'ig. 1. Fig.;6 is a plan view of the y i1/nf lbth platev andthe clevicegeT ltion' is given the lqoper through the medium ofalcsm derside o! the v one side of its pivotal connection.

thereon. Fig,Y 7 is a sectional view'oi the jointed end of the lnchine firm. Figs. 8--9-10 il and 'lZ nrc details tobe referred to.

Referring howto said drawing for a more complete explanation o my invention, A represents the machine arm, which is designed in beappropriately' supported on or secured to a table a. This rm is provided with two bearings a in which ismounted the main shaft B having fixedw it a pulley b in'themsual manner.

-'On s bracket, A depending from the main arm A is fixed the cloth plate e Io the machine and in line therewith, towards thelr left end, isp. movable support ai for the hat-rim and which supboyt iissuitbly held in place by a set screw e4 or equivloiit means, to the channeled guide or block a5 on the' curved -encl A of the' arm A, said curved end forming ahorn and being jointed or pivo'taily connected to tlieferm A at the point 2 whereby it may here' and lowered about its point 2 to facilitate the insertion antiremoval of the The stitch-forming mechanism includes; a i lower thread carrying sewingk needle n which is appropriately hat relative to the cloth plate, as I will hereinafter v more fully describe. 1. v

secured to an, oscillatinand curved needle arm N piv oted on a stud' fn? rojectiV from thev machine arm and which arm N receives oscillatory-motion about said stud from an eccentric n3 n the moin shit and :in eccentric strap n* connected 'to the arm h' at. a point at The lower needle n. has ah thread-'engaging eye-and A operates in conjunction with en upper needle u having a. thread engaging notch or barb. adapted-tengage and carry a thread through the goods'. ,-Thioupperneedle which I will hereinafter refer toas the barb needle, is

which receives its movement from the main shaft B through the medium-of an eccentric-pin disk U3 and connecting rod 1/3..A i t In addition to the foregoing the stitch-forming devices include e. thread loopei t which-:ts shown, is hinged to a rock shaft t, which extends to the right,

said looper'lbeing designed to have a combined oscilletory and ,a backward/and forward movement. This -suitablysecured to avertically'reciprhcal needle barge', i

looper il hinged at t to the rock shaft t', journaled in a bracket' t3 oi the machine arm, said rock shaft being` given a vibratory motion by means oi' a earn groove'ZX madenin, the tsgeof a'disk D fixed to the mairi'shsft B.

`it verticsl'mdtr shaft 'c ijoumaied ma 'bracket or hearing onthe machine' arm and carries at its upper .fend a roller which operates in the cam'groove ,cj the D, thelower end of'said rod being connected to l sind or arm '3 projecting from the rock shaft t whereby the shaft is rocked in itsbeering and a rocking move-1 ment yisimp'rtedto thelooper. The oscillatory is designed to Snap into engagement with a notch or undercut recess in the hinged part oi the arm and thereby hol the hinged portion of the arm ina locked 'posi ron. Tp release .the hinge part of the ami, the pin 3,3' is pushed down until its lower end comes in contact with the free end of the spring plate 80 and thereby forces f the catch of said plate out ofthe recess and allowsfthe "hinged-,end ofthe arm to be lifted to remove the hat.

The locking thread is shown as passing over a suitable4 [v tension device 36, through' the eye 9 of the arm S and acrossthe front of the cloth plate and back oi a tension 40, Fig. 2; and the sewing thread passes over a tension device 3.5v and through guides 37-3'S 39 and the eye of the lower sewing needle, To the iront under- 1'5 side o thebcloth plate is fixed a plate 4l having a yertical portion-42 with an opening in which a'portion oi the vfeed operates. Y

The inner portion of the plate ills provided with a vertical groove or channel Li4 which stands inline with the upper needleand'gudes and receives the point of thisneedle and thereby keeps the needle firm so that the lowerthreadled needle may pass through the loop in forming the-second stitch. The lower end oi the' groove or channel 44 is closed at opposite sides io form -a sheath and brace' i'or the point ottlie needle, as shown in Fig. l2.' The presser foot 46 is also k'provided' with some' suitable form of guide, as 47, for the leather band.' fTlie machine .will be mounted in any usual or well known manner and will bosupplied withsuch com- ,30 plernentary accessories as may be necessary for the Iwork to be performed. f "j Having thus described my invention what I claim as new and desire to secure by Letters Patent iszp 1.
