t Fig..11 is 'a rear face View of a portion of a necktie bearing a label as attached thereto by 's PATENT "OFFICE Y the operation of the sewing machine of this invention. Y I I I Similar characters of reference are employed in the hereinabove described views, to indicate corresponding parts.

In saiddrawings, the reference character I indicates the main body of the sewing machine frameor base-from the top of which extends the arm 2 through which extends the head shaft 3 for operating any well known type'of mechanismfor actuating the vertically reciprocable needle'bar 4 andthe sewingneedle'ii carried by the latter.

Extending'from said frame or base body I is a tubular bearing arm 6 by which the work support of the machine is movably supported. Said work support comprises. a hollow or tubular mandrel 'lhavi'ng a tapered or conical free end portion, preferably in the form of a removable end cap 8; The rearward end of said mandrel Textends within the interior of said frame or base body Land is movably mounted on a tubular bearing hub 9 which is'suitably secured to said frame or base body. Saidmandrel I is aligned beneath the machine arm v2 in spaced relation to the sewing needle mechanism. Formed in the top wall portion of the mandrel l is a transverse slot or needleway l0 which, terminates at its respective ends .in rearwardly directed longitudinal extension slots or needleways ll. Arranged within the interior of said mandrel l, beneath the slots or needleways, is auxiliary sewing mechanism to cooperate with the reciprocating sewing needle!) in the stitch-forming operations of the machine. For the purposes of illustration, said auxiliary sewing mechanism is shown as of the well-known reciprocating shuttle. type l2, although it will be obvious that other types may be employed, such as the equally well-known timed'relation to the reciprocatory movements of the sewing needle 5, comprises a bell-crank lever l3 which is pivotally supported between the ends 'of laterally spaced bracket arms l4 projecting.

rearwardly from the butt of the machine arm 2. To the free end of the vertical arm I 5 of said bellcrank lever is pivotally connected the rearward "end of a reciprocable link l6 which extends forwardly through the interior of the mandrel l,

and with the free end portion of which is connected said shuttle l2, whereby the operative 'movementis transmitted to the latter. Afiixed on the rearward end of the head shaft 3 is a crank.

wheel H which is operatively connected with the horizontal arm I8 of said bell-crank lever by a connecting rod member l9.

'I'helmandrel l is provided with. means for clamping the work and a superposed label thereto subject to the machine stitching operations.

and around the mandrel 1. Pivotallyrconnect-ed with the upper section of said collar 20, by a cross-pin 2! carried by. the latter, is a carrier arm 22 to the free end of which is suitably affixedv Said label frame is 'of opena label frame 23. rectangular shape and transversely arcuate in form to conform to the circumferential curvature of the mandrel l, and'the same is so dimensioned as toextend exteriorly around the slots or needleways Ill-H of "the latter.

A second carrier arm 24 is provided, the same having a bifurcated rear end 25, thearms'zii of which straddle said'upper section of the "collar 20, being 'pivotally mounted upon the ends of the cross-pin 2| carried by the latter. The arms 26 terminate in downwardly and rearwardly inclined lever extensions 27. Pivotally connected, by 'clevis portions 28, with v the free ends of said lever extensions 21 are rods 29, the free end portions of which extend slid- -ingly'through knuckles 3B rotatably mountedin connection with the lower section of said collar 20. Compression springs 3! are disposed about said slide rods 29 between their'clevis portions 28 and said knuckles 3G. Afiixe'd to the free end of said second carrier arm .24, by a downwardly offsetting tail-piece 3 2 "is a label and work clamp plate 33 'of transversely arcuate shape adapted to conform to the circumferential curvature of the j mandrel 1.

When in clamping position, said clamp plate 33 will enter downwardly within the label frame 23 to'iregister within the area defined by the inner margins of the slots or 'needleways ill-I I, so as not to obstruct the passage of'the sewing needlei'through and along the latter during the sewing operations of the machine. If

desired, the second carrier arm z l may have suitably connected therewith a transverse finger piece 34 to facilitatemanipulation of the same.

Provided in connection with the machine arm "'2 is a laterally projecting'bearing arm 35which' overhangs the frame or base body I, and secured "to said frame or basebody I so as to be aligned with said bearing arm 35, in outwardly offset relation thereto, is a "bearing bracket 36. Journaled in said bearing arm 35 and bearing bracket 36 is atransverse'driveshaft 31. Said driveshaft 31 is adapted to drive the head shaft 3 through theagency of intermeshing gears efi'and 39 respectively' aifixed to these shafts. Aflixed upon "the outer end portion of said drive shaft 3! is a drive pulley lfl, and also mounted loosely on said 1 drive shaft 31, outwardly of said-drive pulley 40 is "a'loo'se or idler pulley M.

A drive belt42 cooperates with'said pulleys, and is adapted to be driven from anysuitablepower source. j

--Journaled in 'bearingportions '43, provided in connection with said frame or base body I, is a "transverse counter or jack shaft 44 which is positionedindownwardlyand rearwardly 'ofiset relation to'said :drive shaft- 31. Fixed on the forward end of said :jack shaft 44 is a cam wheel 45 for Ana illustrative form of clamping means suitable for the purpose comprises a split collar 2'i,the sections of which are suitably secured togetheru to controlling and timing the rotative movements i of said mandrel 1. Fixed on the rearward end of said jack shaft is a cam wheel 46 for controlling and timing the longitudinal or axial movements of said mandrel l. The means for driving said jack shaft 44 and the cam wheels 45 and 46 thereof, comprises an oscillator member: 4'! which risqpivotally mounted onv said jack shaft M as ayfulcrum- .Said drive v connected with said oscillator member 41 by a shaft 31 is provided with an eccentric 48 which is connecting rod 49. Fixed on said jack shaft 44,

adjacent-tosaid oscillator member 4?, is a ratchet wheel .50. .Bivotally mounted on said oscillator 3 member d l" isa springpressed pawl 51 adapted to cooperate withsaid ratchet wheel 50. The rotary movement of the drive shaft 31 is trans- 'mitt ed through the eccentric 48 and connectingv rod 491:0 the oscillator member 41. thereby producing operative oscillation of the latter so as to [cause .f the I pawl {5-1 1 to progressively rotate the ratchet wheel 1-50, and thus also driving the j ackshaft]! and-said'camwheel's. v v

The] means for transmitting rotary motion to the mandrel =1 comprises "a vertically: movable rack 52 slidably supported i'inslidewa'y members '53 within= the-interior o-f the' fram'e or base body I adjacent to the forward wall-thereof. Mounted to 'extendcadjacent to and across said rack 52, is a rock shaft-'54upon 'whichis fixed a gear 55 to operatively mesh with said rack. Also 1 fixed on operatively meshes with a gear 51 afilxed tothe rearward endportion of said mandrel l-. iii-fixed "tosaid rack 52-is a-laterally projecting stud'58 which projects outwardly through a slot 59 in the adjacent wall of' said frame or base body [and toward -sa'idr cam wheel 45, and mounted on'the' end of said 'stud is an anti-friction roller 60 which engages-in the race of said cam wheel45. The race of the cam 'wheel45 is formed to provide a rack lowering cam section 6| and a rack raising cam section 62 with intermediate neutral race sections 63 and-164. The rack lowering cam section 6! operates to slide downwardly the rack 52;thus transmitting an upswin'ging movement to the quadrant gear 561 which; operates, through the gear 51, to impart'clockwise rotaryniovement to the mandrel 1 (as viewed in Fig. 4). The cam -sections 6l ;'and '62 are of the sinuous form shown (see Fig." 6)., whereby the produced rotary move "within the interior of said frame or base body l, A

said' rock-shaft 54- is a quadrant gear which ment of the mandrel I is intermittent or step by 2 step in character and timed relative to the recipj rocationsof. the sewing-needle 5,.so that alslighthesitation'or dwell of the mandrel, andthe' work 1 borne thereby, occurs as said needle passes into and withdraws'from the work, while, at the same time, thestep by step progression is utilized to I l '60 V i movementof the'needle 5,..tothus determine the length of the stitches formed by the sewing feed or move the work relative to the path of operationof the sewing'mec'hanism of which said needlefi is a part; H V

"The means for transmitting longitudinal or carried by its lo'wer end is-an inwardly project ing anti-friction roller stud 68 to operatively en- Igage in the-. -annular channel 69 of a thrust collar ll! which is'i'ixed upon therearward end pori-tion offsa'idcmandrel 1; iMountedon the outer Q'slde of saidlever 65, intermediatethe ends thereof, isanj 'anti-friction roller stud H which en- "gages'in the race of saidcam' wheel 4 6. The

andis .yieldably urged toward the latter by spring.

racev of said cam wheel is formed to provide a mandrel advancing and retracting cam sections '12' and 13 with intermediate neutral race sections 14 and 15. are"of the sinuous form shown (see Fig. '7),

The cam sections 12 and 13 whereby the produced longitudinal or axial movements, in bothdire'ctions, is intermittent or step by step incharacter andtimed relative to the reciprocationsof the sewing needle 5,"so that a slight hesitationfor dwell of the mandrel, and

the work borne thereby, --occurs as said needle passes into and withdraws from the work, while,

- at' the same time, thestep bystepv progression is utilized to teed or move the work relative to the path tr movementof the needle 5,- to thus determine the length of the stitches'forme'd by the sewing operation of the sewing mechanism of which said needle v a vmm "I'he novel sewing machine is provided with means for manually starting its operation and thereafter automatically stopping suchopera [tion when the sewing on of :a label or thelike toagiven article is completed. This'means comprises a stop dog 16 pivoted at its lower end by alfulcrum knuckle 11 which projects from a bracket plate 18 mounted exteriorly on the frame or base body I. The free end of said stop dog 16 means 19 disposed intermediate the stop dog 19 andsaid bracket plate 18. Mounted in theiree end portion of said stop doglB is a spring projected stop bolt 80. Aflixed on the rearward face of said drive pulley .40 is a stop; collar filhaving an eccentric periphery terminating at its high side in-a radial stop shoulder 82,.contiguous to the bottom of which is atransverse check. groove Q 83 (see. Fig. 8). Affixed to the upper free end of said stop dog. 16 isa belt shifter 84," through i the loop of which passes a run ofthe drive belt 42. 'Pivotally .fulc'rumed between bracket ears 85, which project outwardly from said bracket plate 18 in straddling relation/to said stop 'dog 16, is a bell-crank lever, the inner vertical arm 860i which extends downwardly along the outer face of the stop dog 16,'while the. horizontal arm 8l1u0f-WhiCh projects outwardly'and maybe manipulated by hand, or, if desired, maybegzconnected-by' a pull-wire :88 with a foot pedal (not shown) soas tobe. actuatable by the ,machine operators foot. Cooperative with saidrstop dog ll; isv a detent member 89 which is :pivotally mounted ,byitshub Si! in connection with said ;br,acket plate 'Hlso asto swing inhor izontal ,plane toward and from a side of said stop dog.

' Said detent member 89 is provided with a latch nose 9 I; to -engage a chamfered latching lip 92 with which said stop dog is provided.

Saidreleasing means comprises -a worm-wheel 96, rotatably'mounted on a bracket bearing 9.! carried bysaid bracket plate l8; so as to turn" in horizontal} plane. Said worm wheel is driven by a'worm gear 98 whichisfixed onthe against the mandrel 1.

2,189,045 p i drive shaft 31. Carried by said, worm wheel 96,

in dependent relation to the'underslde thereof, is ,a trip stud 99,-,which is adapted at proper times to engage said trip nosingf95 of the detent trip arm 94. i 1 v In the use of the machine, thesame being in stopped condition, the operator raises'theclam'p' plate 33and the label frame 23 to open position shown inFig. 3, and, thereupon slides the work to be'labeled over the free endof the mandrel 1 and beneath the raised clamp plate and label frame. Illustrative of the work, the same may be a necktie T, across the lapped backfolds of which it is desired; to sew the label L. ,Insuch case, the necktie T is slid onto th'e mandrel with its rear face uppermost, and sothat the mandrel passes between the front -and backthere-' of in underlying relation to the latter. When the necktie T is inposition beneaththe raised sewing needle 5, the'label'ir'ame 23 is lowered,

and thereupon the label '1 is laid over the-rear face of the necktie within theilabel frame 23,by

which the margins of the label aredisposed'in register over the needleways lD--ll of said man- 'drel, whereuponthe clamp plate 33, is lowered to clamp andfirmly hold the tie and labelgripped With the" work positioned as described, the operator starts the machine. This is done by pulling down the horizontal arm 81 of thebell crank, thus swinging inward'the vertical arm 86 I thereof against the stop doglfi whereby thelatter is swung rearwardly to withdraw the stopbolt 80 from the path of the stop shoulder 82, while at the same time movinginwardly the belt" shifter 84, so that the continuously movingpower' belt 42 is shifted from the loose or idler "pulley,

4| .onto the drive pulley 4U. The stop dog is held res in the described released or retracted position by theengagement of its latching lip 92 by the latch nose 9| of the detent member 89;

As the drive beltfidZ engages the drive" pulley .40 operation oi the machine is inauguratedythe sewing needle 5 begins its'verticalreciprocation and cooperation 'withlthe other elements of the. stitch forming mechanism, and simultaneously thetmoverjnent of the cam wheels and Mibegins! Itis'preierable, although not essential, that the stitchingoperations start from the middle of the transverse needleway-Hl proceedin thence to onelongitudinal needleway I I. In

such case, the starting point of an operative cycle of movement of the. cam wheel this lo cated midway of the ends. of one of the rack actuating cam sections of its raceyas e. g; the

sequently a series of stitches along the longitudinalmargin "of the'label L is formed, until the end of the transverse needleway I0 is reached, by which;time the rack 52 isstopped at the limit of its downward movement and there caused to dwell'as its stud roller (illenters and rides through the neutral cam race section 63. Immediately such rotative movement of the mandrel; and-work ends, the cam wheel' lli, which j revolvesincompan'y with the-cam wheel 45, hasbrought-Queer its trace cam sec on a l ;nto .en aeementrwith the studrdler of h lever 65, whereby, as said; can; section moves relative to said stud'".roller,;saidwlever 65 is causedto swing forward and back, thus axi'a lly moving themand-rell, and work clamped thereto, step 'byqstep forward and back in the directions {of the arrow a in Fig. 2 and consequently stitch- :lng, along an: end margin of the label L is formed, until the -sewing needle ,5 is returned to; the juncture of .the operative :needleway ,II and said transvei' seqneedleway. J9, by which time the leveriilifiisgstoppedin initial position and there caused to} dwell as its=;stud roller entersand rides through the neutral cam race section 74 of the cam wheel 46.: Immediately such axial movement of the mandrel ceases, the rack raise ing cam section, 62 of cam wheel-45 becomes operative, thus causing a rotativemovement of the mandrel and work in the-direction of-the arrow y in Fig. 2 with stitchgforrning efiect, until the Opposite end of the transve'rseneedleway M .is reached, by which time the rack 52 is s opped at :the limit of its upward movement and there caused to dwell as its studroller 60 enters and rides through the neutral cam race section 64.

Immediately such rotative movement of the mandrel ;and work ends, the race cam section 13, 110i cam wheel 46 becomes-operative, thus caus-j ing a second axial movement of the mandrel and work-in the directions of the arrow bin Fig. 2', with stitch forming effect along the second needlewayjrl I, and until the juncture of the latter with the-transverse needleway Hlis again aligned with the sewing needle 5, whereupon the neutral race section15 of cam whe'elrfi becomes ef-. 'fective, and the cam race section i 6! of cam:

wheel 45 again becom-es efiective to rotate the mandrelyand work back to initial starting position. 1

'It will be observed that the cam wheels 45 and it-haveftheir operative and-neutral race sections in alternated ei'r'ective relation, thus timing the operations of the sewing mechanism to stitch along one-longitudinal margin and along the end margins of the label Is. As shown ;:and

above described, the arrangement and operation is such that a double line-of stitching is produced. It will'be obvious, that variations in the relative arrangements of the operative and neutral race-sections of 'thecooperating cam wheels can be made, so .as-to begin and end the stitch ing operations at'any'desired portion of the :label ,stopping the machine upon completion of the stitching operations is as follows:

Theoperation of the means for automatically When the stop dog -15 isv swung backas described'to shift the drive belt 32 onto the drive pulley d0, the detent member 89 will engage and hold said stop dog '36 in such out-of service position. Asthe machine proceeds to perform its cycle of operation, the worm gear 98 willcause the worm wheel 96 to revolve in such manner and timed relation to the machineoperation that,

upon completion of the stitching, the trip stud 9Q carried by said wormwheel as will be brought ,into passing engagement with thetrip nose of trip arm 54. Such engagement will swing said trip-arm 94 so as to transmit an outward swinging movement to said detent member189 (see Fig. 9) thus. releasing ,its restraint upon the stopdog 7B.

Such operation assuresa full stop ofthe driyepulley lflwithout risk of either back-lash or.;carr yv f. x over thereof under momentum, and ,consequent i ly alsoyassuring the full stopping of the sewing mechanism and work support in anaccurate nor mal initial position. The outward movement ofv the stop dog 1 16 to operative position as described, also movesoutwardly the belt shifter '64, "thus shifting the continuously running drive belt @2- onto-the loose or Iid-ler pulley i-l g j When the machine is 1 thus automatically stopped upon completion of agiyen label sewing ;-operation,-the :work and label'clamp'utt maybe released and the label frame ilfl' raised so that" 3 I the tie T may be removed from, the m'andreldft and another tie vT and label vap-plie'dto thelatter erations.
