Application filed March 221` 1918. Sera1No-225329.

To'u/l whom 'it may ron/ern Betit known that l` -Roni-arr Cain. kann, citizen of the llnited States, residing at vWvomissing. near Reading'. in the eounty of 5 Berks and State of lennsvlvania. have invent-ed certain new andy useful Improvements in Braiding-Carrier Dive l\l'eehanis.n, of which the following' isa specification.'

i My invention relates to braiding c'arrier 1.0 drivemeehanism comprising elutehyenlaged driving and driven members. as illustrated in my 'Patent No. 1,256,038 issned Feb. 12,.

1918; and it consists in the improved eonstruetion hereinafter folly deseribed In con- .neeti'on with the accompanying drawings and vthe? novel features of whieh are defined in the Suybjoined claims.

rllrel'general purpose of the present invention is to provide a self-eontained earrier 2,0drive mechanism applieable to the usual lbraiding maehine without speeial provision therefor; and the main novel featuresronf sist first iii-providing upon tlie fixed carrier postY a stop devlee adapted to retain the driven member against rotation when it is disengaged from the drivin;y member. and seeondin providing' axial eluteh operating` means in eonneetion with said post, as fully set forth in the following deseription of the embodiment illustrated.

Figure l is a sectional elevation of a lmechanism embodying' in v eomplele inven- E'Ation. shown in eonneetion with the lop and bottom plates of an ordinar)Y braider: one

of the duplieated eluteh pins being removed.

and a portion of the stop follar being' broker away to more elearljvv show the eoustruetion.

Fie'. 2 isa plan view of the same. with the carrier drive disk removed but indieaied in 40 dotted lines together with an :aljaeem portion of the tt p plate of the maelune.

Figs. 3 and -l a re detail views of detaehed parts..A

The drawingl iudieates the top plate 5 of a braiding niaehine formed as usual with inearl-ier terseetingg,` raee-eireles in whieh drive-disks 9 are rotated to operate engaging bobbin earriers; these. drive disks being intermittently rotated as in laee making braiders, by providing 'for Clutch-rontrolled engagementof im'lependently rotatable drivingr and driven members 1G and 11 respectively on each raeofeirole post 15 rising from the bottom plate of the machine.

ln the illustrated embodiment of my cornplete invention the raee-eircle post 15 earries` the entire eluteh-emitrolled carrier drive*mechanism. so as to enable its use in place of the ordinaryY braidingr drive mechanism without special provision .in the maehine for its attaehment.

The post as shown, is formed hollow. and Contains a central eluteh-operating device 16, to which pattern-eontrolled vertical movement is imparted; sueh movement beingrel'teeted through a-bel'l-e 'ank lever 17 pivotally attached to it belooft-he plate-secured base of the post andarranged to fulerum against a bracket lixecl beneath the plate as indicated` in eonneet-ion with an interior spring 1s.' The top of the post is provided with a stop eollar 1t). fixed thereto b vione or more screw kevpins 20 as shown, and provided with a Hotell-engaging rim recess il hereafter referred to. The top of-the eentral eluteh-fmerating member 1G is pro` vided with a eluteleengagriney tiange 22, by means of whieh the elnteh pin or pins earried by the driven earrier-disk member l1 are moved longitmlinally to engage or disengage the tooth projeetions 2G on the eonslantl)Iv rotated driving member 10.v

'l`he driven member 11, whieh comprises as shown a dependingl hub portion fixed to the rarrier drive disli S) by screws at Q'alldbearing' npon the driving member 10, carries the eluteh pins 25 in vertiealrgnide ways() as indieated: eaeh of said elnteh pins havingA a radial side slot 2551 in which the .oireular ttanyge 22 of the central clutch-.operatin;` deviee it is eonstanlv engaged so esto eause vertieal movement of the clutch pins with said operating' device while permitting remiv movement of the driven member HMH with its emitained clutch pins 25 on the non-rotatable ope 'ating device 15. As shown the latter is held against rotation by engagement therewith of the 'extended key pins 20 which tix the, stop collar .1h to the post.

`When the slidable clutch pin' or pins 25 are lowered to engage the driving member 1o, it if; be free to rotate with said member 1.0 upon the fixed postl and its central cinte-hpp eratinrY device to; but when said clutch pin is in t'lisengaged raised position as indicated in Fie. 1 said driven member should be reolnired that the driven member 11.
