- Beit lmown that we, JOHN W. Renners andARrHUR' l?. lB imwsrnn, citizens of the United States, residing at Passaic, in the county of Passaic' and State of New Jersey,
have invented'certainfnew and useful Improver'nents in Stop Mechanisms" i'yrSew4 ing-Machines; 'and we do herebyy declare the following to be a ull,xclear, and exact description of the invention, .such as will enable others skilled 'in' 'the art towhich it -to lcause the machine appertams to malieand lus'ethe same, referbeing had to the accompanying drawings, and to figures of reference marked thereon, which forma part 01El this specification. l
This invention relates to a sewing-mawi-th a clutch,. and comprises a machine having means which means is operated by -the machine to stop when the thread 4breaks in tbe'machine, or when the 'i spool of thread is exhausted or when the i l 1 l thread. in the shuttle is exhausted.
The mechanism consists of an apparatus,
preferably operated from the needle bar,
' which apparatus disconnects the clutch when engaged thereby, but which engagement, under normal conditions, the tension of the thread in the machine so that while the thre d isunder a tension, said tension being -due to the thread not broken or not being exhausted, lthe .rupti'onp This mechanism is particularly adapted iorsuch lmachines as areused'in numbers 1nv a factory where one Ioperator. attends to a rial Abeing case of 1 number of machines,
4and where 'sometimes a machine' will still be running but. feeding material therethrou h without said matesewed, -suc as for instance in the emstitching machines, Where. one operator has a'number of machines, and even under careful supervision a machine will sometimes operate for al considerable length ottime without `thread, thereby damaging material that passes through-.1t and at the .same time .not being productive,
- device'.

"of 'clutch' can is prevented by 82' to.' the needle The inventions panying drawing,
Flglue in whichl 1s an side view of one end ratus. Fig. 2 is va showing the` head and part of the arm of the Specieten ofLtte-rs Patch# Patented0ct.29,19l12. Application iledDecemberw, 1911. Serial-No. 667,579.
` `ustrated in the accomend view of'a sewing-mia@4 chine equipped with our improved appa machine, and Fig. 3 is a section through a sleeve carrying a finger employed in the Any form oimachine 10 .can be used, and
we do not limit ourselvesV to any particular type of machine, which machine has 'an arm ll provided with a head l2thereon, wh1chl head 12 has a reciprocating needle bar 13 therein which is provided with fa needle 14:'
which reciprocates vwith the needle bar and passes in' the usual way througha 'recess'in a presser-f0ot 15. l
The .machine is -operated from a flyiwlieel 16 which is driven and fly-wheel are thrown intogand out of by a lbelt 17, which belt operative connection by means' of ajclutch 18 which is simply in Fig. 1 so as toindicate it, since any kind be employed, as willi be 'evil l So far as isnew." fi. v Our inyention resides in the means for operating the clutch from the needle bar,
vwhich invention is as follows: On the needle bar 'lwe arran e a trippmir arm 1 9 which- 4projects?throng .-a slot 25 in the head. Mounted'fon the' frame of the iachine isa sleeve 21 provided with a stud ..2 on which the sleeve is adapted to swing, the sleeve being limited in its movement by stops 23; being leld to the limit of its movement in one direction by aspring 25. Slidnbly arranged in the `sle`eve 21 is a finger 26 which is normally held yieldingly in its position by aspring 27. It will thus be'seen that the finger -is ca able of both a longitudinal movementv an Suitably arranged on the sleeve is athread guide 28. The thread is conducted from the 'spool 2 9 to a tension take-up Varm 31'and through the thread guide 28, and ltheirconducted-'over the guide vifiannd is4 fed through to a transverse movementshown in dotted outline described nonesof the .machine vdevice 30 over the --connect vvithtlie threadfrom thevshuttle 35,
which shuttle is simply shown in dotted outline and is not illustratedfindetail, sinceA any form of shnttle yc'a .n.-be -iised,rand itfwill be evident -tofanylone skilled in the art. ho\v -this 4shuttle operates andwhere it is located? The ithr'ead "from the shuttle 33. combines .'With the threadfrom .the spool after they have been knotted' together by-the operation of .the '.-machine, softhat abreaking of thethread orthe'exhausting of the tread from the spool or from the shuttle willvcause'the ithread to lose its tension, and the sleeve 21' is held by'` the. springj`25- inthe position shownfin F ig.- 1, and When-the vneedle bar comes dovvnl the-tripping. arm 19 engages *A .the'top end of the finger 2 6 andpushes it down so that thelowerendengag'es a' lever 40. which in turn releases the pin. 41 ofthe settin arm 42, and-this' in turn "permits the' pin- 3 of the clntch-oper'ating' .arm- 44 to .permit said clutch-operating arm'to be acted.
Qnby the spring45', the arm44 extending u arond andbeing shown ill-dotted lines adjacenttof the-clutch 18, the swinging not the arm 44 permitting said. clutch to' become disconnected `and thefmachine stops.. Wh-en the clutch is 'tobe reset,- the finger-piece 46 Y yon`the-rod 47 is pushed down, to which rod the setting arm 42. is attached. lThis arm pushes vthe pin43 t swing the arm 44 over to connectthe clutch 1S-'at the 'same time, the pin 41 of thefsetting arm42 engages a recess 48 in the tripping' arm, 3,9, and the tripping arm .in turn permits the lever 34to assume its normal position.j When the thread is 'rovided 'with its normal tension, however, operation does not take place, since the tension' on the thread,V when the .tripping arm" 19 is. descending with the needle bar,- isstrong 'enou to .move the ,sleeve 21 against the light spring 25 and the finger 26 1s moved from the path of the tripping arm 19 so .thaton reach descent-v of the needle 'bar,'the tripping arm 19 descends and-'rises'agai'n without engaging .the end of theinger26, lbut while the tripping arfn is above the'in er 26, thetension on the 'thread is`re1axe due to the take-up that previously took place while the thread was under' tension, and the sleeve-.isi thus being constantly'swung'into and out 'ogfthe path' of the tripping arm 19 according as the tension on thethread is increased and dil minished by the operator ofthefmachine,"
- The device is compact, easily installedl on.
any type of machine now in use, a'nd 'is positive in its operation. setting device for the clutch is thought to be new and provides a .means for setting the -clutch again "bythe operator from 'the part of the machine adjacent to'the needle, which makes'it handy to start the machine out tension enough to cause a stopping ot .the machine.
Having thus described ourinvention,what
we claim is:.-"
