Serial No. 296,65'7Q y n e i n relates t t i ger ac u t d latches for movable members, of a type particularly adapted for useina stop motion mechanism for braiding machines adapted to braid cord arounda pluralityof elastic cores.

Due to the'force of the v relatively heavy sprin 'l referabl employ to actuallyactue P Y provide a quick acting and sure stop motion mechanism for the machine if anything, quicker thanany type of electric stopmotion mechanisms.

A further obj ect of my invention is to provide stop motion mechanism of this type.

Which may be readily connected to a braiding machine Without in any respect modifying the constructionthereof. I merely insert the beam for the elastic-cores having the necessary parts of mystop motion mechanism at tached thereto underneath the braiding'machine'and attach a rod therefrom to the usual stop motion mechanism of'the braiding machine. V c

A further object of my invention is to provide a trigger actuated latch'for thisor any purpose WhlCl'l'lS releasable on .a relatively light force to permit a relatively heavier force to act and particularly Where a large fo ceisr q r te l sws or iQn l e c I carrier 1s PTOVIdGd' W1 anism or for any other desired purpose.

a In the drawings; Whereinlike characters of ably supported; by the reference indicate like parts throughout l0 generally'indicates a, braiding machine of v "the.fi airie 12 suitlegs ll'rnounted on a suitable table or stand 16. The

so braider car riers18 revolve-asusual in the sinuous cr0ssc tracks n'the top plate 20 and are driven as usualby the gearing 22 su tably revolved by the pulley 24 Between; the gearing 22 pulley i thereis interposedthe usual clutch 26. I

The frame 12 is provided with thesuitable holes 27through which theelastic cores 28 may them the usual cord. 1

be led tohav e braided around While my elastic core stop motion mechanism may actuate any desired type of stop it to motion mechanism I preferably soconnect' v the braiding .machine that'it may act upon thealready existing type of stop motion mechanism already built on most types of braiding machines to stop the machine 'When a thread or acid in one of the braider' reason, each braider carries breaks for any eight so slidwe" ably mounted on a post 32 thereof normally held up by the cord during the braiding op III oration and adapted toslide down the post 32 to move over the pivoted lever 34 to actuate the stop motionmechanism as the lowered weight comes adjacent to the lever 34 as the carrierwindsaround the sinuous with the functioning of crossing tracks after breaking of the cord.

36 represents the main drive shaft which has mounted thereon the driving pulley 24 and which has on its-ginner' end the. bevel" gear 37. Said bevel gear 37 is adapted to mesh as usual with the bevel gear 38 loosely mounted on a revolvable upright shaft 40. Said upright shaft 40 has keyed 'th'eretothe driving gear 42. lChe braiding machine is provided with the usual clutch 26 which preferably includes comprising a clutch fork 44 adapted on the upward movement of "the shipper handle to causethe driving gear 42' to revolve with the-continuouslv revolving v bevel gear 38. The braiding machine 13 norpivoted lever 34 to'release the clutch 26.

It isrthus apparent that the only modifications of a standard braiding machine necessary are to provide the holes 27 in the frame thereof and means forattaching the rod to the pivoted latch 46.7 j

V The elastic cores 52 are suitably mounted as usual on the beam 54in'ormalylocated un- V dern-eath the braiding machine; said beam 54 7 being provided; with the usual weight brake 56. The elastic cores 52 are suitably wound individually on different portions of the beam 54. Although my improved trigger actuated latch for the movable member may be actuated bv a single light moving strand, as

shownin the drawings or otherwise it is pref erably so constructed as to be actuated on the breaka e of any one of the elastic cores 52, of which there may be eight as shown in the drawings. l/Vhile any suitable type of latch means may be employed on a portion of the beam stand 58 underneath. the beam 54, I preferably suitably piv'otably mount the arm 60, Said arm 60 has the free outer endthere- V of connected to the rod 50 and an enlarged curved portion such as the disk 62 near the pivot point thereof having a notch 64 on'tlie upper portion of the periphery thereof. I

provide a relatively strong spring 66 con nected to the rod 50 to moveit downwards to actuate the stop motion mechanism having the opposite end thereof suitably connected to the beam frame 58, and suitable means to release said notch means to permit the spring to move said rod. In my preferred embodiment I provide gravity opera-tive pivotable triggermeans operative to release the latch means to permit, the spring 66 to move the rod 50. The trigger means includes the pivotable trigger shaft 68 normally biased against gravity by the relativelylight force of an elastic core and I- provide means such as a slidable weight 70 operative on breakage of saidcore to increase the gravity m0- ment of said trigger shaft sufficiently to release the latch means. While any suitable type of latch means may be GITIPIOYQdfI preferably employ thepawl 72 suitably pivotably mounted on the beam frame 58 to have'an end thereof re; oted arm 60. .t V

' In my preferred embodiment, the latch gister in'the not-ch on said pivmeans also includes the lever 74 suitably piv-' ot-ed at 7 6. to the beam frame 58 adjacent said pawllhaving the work arm 7 8 adapted to abut the free end 80 of the pawl 72. The power arm 82 ofsaidelever 74 normally projects upwardly." ln the embodiment shown, the pivot of the lever 7 4 comprisesthe pivot rod 76 ,extending underneath the beam 54and 7 parallel therewith. The trigger meansin- Ycludes a plurality of pivotedtrigger shafts 68- one for each coresuitably pivoted as at 84 to an extension of the frame 58. Each triggeri shaft has the spool 86 revolvably mountedon the normally raised end 88 of the power arm thereof adapted to receive the elastic core 52 to normally retainsaid power arm88 in raised position; Each trigger shaft is also provided with a suitableslideway comprising the rod 90 which extends from substantially the pivot point 3340f said'shaft'along the 1 I also provide "a 6 power arm 88 thereof. weight 70 having ahook 71 for mounting on said rod QOadapted in normal posit-ion, of each trigger shaft 68 during the operation of the machine to lie. as shown in Fig.4a relatively small distance from the pivot point 84' thereof. As also-shown diagrammatically in Fig. 4on breakage of the core 52, the power arm 88 of said trigger shaft 68 will drop and after itpasses the horizontal the weight 70 will slidevrdown the power arm of'said' shaft 68 to increase the force of the gravity moment thereof to increase the upward force of the work arm 89 'ofsaid trigger shaft striking the power arm 8910f the lever 7 4 su'liicient ly to knock the pawl 72 out 'of the notch 64 to permit the spring'66 to move the rod 50 to actuate the stop motion mechanism. It is thus obvious that the latch means-will release by the dropping' of anyind-ividual trigger shaft 68 on the breakage of the core.

In a light braiding niachi ne a single trigger actuatedlatch is'sufiicient to release the stop motion mechanism but particularly on and carrier or larger braiding machine in order to increase the force acting on the movable member-r rod 50 stuiiciently to release the stop motion mechanism, 1 preiierably connect two or more oi? my spring actuated latches in series as shown in Fig. 5 In Fig. 5 the lever 74 is released as usual by the trigger'shaft on breakage of a coreto knock: the

, pawl 72 out of the notch 6% in the pivoted "no-er 9E will also be depressed to knock the pawl arm which will permitfthe relatively light spring 66 to movefthe rod 92. TiZherod 92 however, is not connected directly to-the stop motion mechanism but a second 'sprmgac- 'tuated latch similar to the'spring actuated latch I normally employ isinterposed lee-yt-ween' said first spring actuated latch and the stop motion mechanism connection also suitably pivot the arm 94 to a portion of the beam frame 58and connect the free end thereof to the movable rod 92. I also pivotably mount a'second pawl 96 .on said beam frame 58 adapted to havethe free end thereof contacted by the pivoted 9 L- Said paw-196 is adapted to register in a notch 98 96 out of the notch-98in the pivoted rotatable member 100 to permit the relatively heavier spring 104 to depress the" movable rod 50a actuate with great force the: stop motionmechanism; If it isdesired tostill further increase theirforce it is obvious that additional spring actuated latches may be connected in series.

When the vtrigger actuated latch has func tioned to stopthe machine, it is obvious that it will be necessary :tore-set thepawl and trigger and suitablysupport the power arm oi the trigger by a new: elastic core. It is apparent that I have provided a very quick and sure stop motion mechanism of suffic ent strength to stop the machine and normally s held in raised position jbythe r'elatively lightfo'r'ce only of a moving strand;

l/Vhile I have shown my trigger actuated V latch attached to a braiding machin it is obvious that it may be employedin any case where it may be desired to move a member for any-purpose on breakage of a lightmoving strand, in otherwise-.
