This invention-relates to a stop motion for circular knitting machines and more especially to the type of knitting machine known as the Scott & Williams ES or P & W variety.

In machines of this type, there is a rotating head having a plurality of radially movable wrap fingers which are adapted to move across the needle circle at predetermined times and wrap a thread around the needles for producing wrap stripes. This rotary head moves in timed relation to the needle circle and has means for mounting a plurality of packages of wrap yarn thereon, which wrap yarn extends from the packages of yarn upwardly through certain tensions and through certain spring tensioned take-up arms to the wrap fingers. These machines have heretofore been equipped with centrifugally operated means which normally project outwardly, and are held in elevated position by means of the tension in the unparted strands of yarn. There was a mechanism of this type associated with each wrap strand having a single tension means. In the event of a parting of the strand adjacent the needles or anywhere between the needles and the spring tension means, the spring tensioned arm was allowed to move upwardly, which in turn allowed a centrifugally operated member to swing outwardly and downwardly to horizontal position where it engaged a suitable member which operated the stop motion mechanism. However, there has been no means provided in a machine of this type for stopping the machine until a parted strand, which becomes parted immediately after leaving the yarn package, passes through the tension means to where the tension arm is allowed to move upwardly. This necessitates rethreading of the yarn after its ends have been tied together through the tension device and often times the yarn would pass off of the spring tension arm and down into the machine on its travel to the wrap fingers which required quite an amount or time to rethread the wrap yarn upwardly through the tube leading down to the wrap fingers and over the spring tensioned takeup arm and through the tension device and securing its end to the end of the yarn extending from the yarn package.

It is therefore an object of this invention to provide an additional centrifugally operated means associated with a modification of the first centrifugally operated means and normally held in elevated position by the tension of the strand between the two tension devices, and which upon a parting of the strand, as it is drawn from the wrap yarn package immediately after it passes through the first tension device, will relieve this second centrifugally operated means and allow it to swing downwardly and outwardly by centrifugal force into the path of one end of the conventional movable lever which will cause it to engage this lever and trip the stop motion mechanism long before the yarn has passed through the two tension devices and extended into the vertical tubes leading to the wrap fingers. This greatly facilitates the amount of time required to tie the broken strand together and resume operation of the machine.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds, when taken in connection with the accompanying drawings, in which Figure 1 is a top plan view partly in section and taken substantially along the line ll in Figure 2;

Referring more specifically to the drawings, numeral l0 indicates a portion of the super structure frame mounted on at Scott & Williams ES or P and W machine, this machine not being shown except for a portion of the needles I! disposed in the needle circle. This framework It has projecting upwardly therefrom a driven shaft [2 on which is mounted a bracket I3, said bracket having an inwardly projecting arm l4 on which is pivotally mounted as at l5 a lever 16. The shaft l2 drives, by means not shown, the cam shaft 39 andthe housing 3| to be later described. This lever It has a projection I! provided with a set screw 18 for limiting its swinging movement in a counter-clockwise direction in Figure 1 under tension oi a spring 20.

The lever I6 has secured thereto at one end thereof as at 2| a wire 22 which is encased within a coiled wire 23, the coiled wire 23 being clamped in position as at 24. Wire 22, as well as its encasing coiled wire 23, is broadly referred to as a Bowden wire and its other end of course has the coiled wire .23eclamped tottheirameiof the machine whereas thewire 22cis:connected -to a suitable latch which is conventional and which normally holds the belt shifting apparatus inea position to hold the belt on the tightpulley, but when unlatched by movement of thewire'22"'allows the belt shifting apparatus to moveathebelt to the loose pulley to thereby stopprthe machine as will be later explained.

Each-of-c-the tension andstop-motion devices comprises a laterally: projecting shoulder 60 extending from-v one side of the rbracket 45 which has three vertically disposed slots therein which are open at their upper ends, and these slots are defined by the three vertically disposed projections El, 62 and 53. These slots between the projections SI, 62 and 63 and the main top portion of the bracket 45 are penetrated by a pivot pin 55, on which is pivotally mounted a tension take-up arm I56 having a hook 61 in iitsl-freerinner end and'having a tension spring :GSJSecure'd intermediate .its ends asat 10, the other end of the tension spring being secured to the upper end of a spring perch H, which rises upwardly from the upper end of the bracketee'remotefrom the observer in Figure 5. This tension take-up arm 63 has an upwardly turned .ho'okedrpottion 72 on its outer end, providing a cavity i3 inwhich the horizontally projected "end "14 of an "uprising mm 15 normally rests due to compression spring 16 which presses against a tension disk Tl mounted for vertical sliding movement'on abolt 18confined by. a.-tension adjustingnutfw andia'. lock nut=8il.

L'Pivotallymounted -onthe pivot-pin between the projections 62 and 63 is a centrifugally perated member broadly designated by reference character I I5, This member has an outwardly projecting arm H6 and a downwardly projectin lip I I! which is adapted to arrest counter-clockwise movement of the member I I in Figure 4 when the leg H6 is moved by centrifugal action to horizontal position by reason of the fact that projection III will engage the lower end of the slots in the projecting shoulder 66. The member H5 has a shorter leg M8 to which is secured as by welding, the upper end of a wire I26 which projects downwardly and then outwardly and has a horizontally projecting portion I2I which projects toward the observer in Figure 4, this horizontal portion I 2| being adapted to pass through the slot 94 and to have the yarn 43 pass between the portion I 2I and the upper and lower legs of the plate 93. This will tend to hold the arm H6 in the upraised position as shown in Figure 4 as long as tension is present in the yarn 43 while passing between portion I2I and the plate 93.

Also pivotally mounted on pivot pin 65 and between upwardly projecting portions 6! and B2 is another'centrifugal responsive member broadly designated by reference character I25. This member I25 has an outwardly and upwardly projecting portion I26 which is normall held in elevated position as shown in Figure 5 when there is proper tension on the strand of yarn 43 while it is passing through the hook 6'! of the tension or take-up arm 66. This position is a result of the yarn tension arm 66 engaging the upper side of a pin I28 in the downwardly and inwardly projecting leg I29 of the member I 25.

The lever I6, when moved by one of the members I I5 or I25, moves the wire 22 to release a conventional latch to allow stoppage of the machine, such as by shifting the belt from the tight pulley to the loose pulley on a knitting machines main drive shaft, This wire 2i extends down to the framework of the machine and the coiled wire 23 is clamped in a fixed fitting I46, and the wire 22 is secured as at MI to one end of a bell crank lever I42 provided on the bed plate of the machine as at I43 and has a hook I44 on its other end for holding an arm I45 secured on the upper end of a shaft I 46, which is biased normally to move in a counter-clockwise manner in Figure 1 so that when arm I45 is released, the belt will be shifted from the tight pulley to the loose pulley by means such as shown in the patent to Ruth, No. 2,389,688 of November 27, 1945.

Method of operation During a knitting operation, as previously explained, the casing 3| along with the wrap fingers 33 are rotating at the same number of revolutions per minute as the needle circle. The wrap yarns which are engaged by certain selected needles pass upwardly through the eyes in the wrap fingers 33 and through the tubes 49 and over the hooks 61 and hold the take-up arms 66 in approximately the position shown in Figure 5. This causes the arm 66 to engage the pin I28 in leg I29 of centrifugal responsive member H5 and holds its leg H6 in elevated position as shown in Figure 4 so that as the table 44 rotates these legs I I6 will not engage the cam 26 of the stop motion lever I6. In the event the wrap yarn parts at any point between the needle circle and the tension disc 17, this will allow the tension take-up arm 66 to move upwardly to the position shown in Figure 4 and this will allow th member I25 to assume the position shown in Figure 4 so that its leg I26 will be in horizontal position as shown in Figure 4, and this will engage the cam 26 and operate the stop motion mechanism of the machine. Now the wrap yarns during operation are also passing between the portion I2I of arm I20 which is secured to the leg I I 8 of member I I5 and this holds the leg I I6 in elevated position, as shown in Figure 4. In case of a parting of the yarn anywhere between the wrap yarn supply 43 disposed on the cop 42 and the tension disc II, this will thus cause this yarn to pass from between the portion I2I and the plate 93 or slacken at this point and will allow centrifugal force to move the centrifugal member II5 to the position shown in Figure 5 and thus the leg II6 will be in horizontal position and when it moves around to the cam 26, will engage this cam and operate the stop motion mechanism.

It is therefore seen that there are two cooperating stop motions, one which operates to stop the machine in case of a failure of tension in the yarn between the upper tension disc I! and the needle circle and the other stop motion which will operate when ther is a lessening of the tension in the yarn of a predetermined amount anywhere between the tension disc I! and the tension disc IIII.

In the drawings and specification there has been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only, and not for purposes of limitation,,the scope of the invention being defined in the claims.
