The said invention relates to a stop mechanism for knitting machines and it is an object of the same to provide a stop mechanismV vide a device of the character described whichV will be simple in `structure and inexpensive and which may be attached to existing ma- Y chines without `any particular difficulty or expense.
This application is a division ol applica- I tion No. 346,681, filed December 22, 1919, the
Patent No. 1,661,485, February 28, 1928.
In the drawings,
Figure 1 is a fragmentary perspective of the invention, and Y Figure 2 a plan of aportion thereof with parts broken away. f
Referring to th .drawingsreference charn acter 10 indicates a part of a knitting machine trame having slidably mounted therein a vertical rod 11 which is pressed downward by a spring 12 located between an abutment 13 on the rod and an outwardly extending flange of a bracket 14 secured to the frame 10. TheV bracket has two outwardly extending lianges having'openings in which the rod is slidably mounted, the lower flange having an opening to receive a spline 15 by whichrotation of the rod is prevented. Y
At its lower end the rod11 is adapted to rest on or strike against a member 16 of the stop mechanism which member in the machine is a part of the means for shifting the belt from a fast pulleyto a loose'one and vice` Y versa, but which may control' or operate a clutch-shifter, an electric circuit breaker, etc.,
according to the nature of the machine. At its upper end the rod is cut away cireumferentially to provide a shoulder adapted to engage over a trip lever 17 pivotedon a support 18. The free end of the lever 17 is ad- .jacent to the sinker cam ring 19 on the rotary head of the machine and is adapted to be moved in a direction torelease the rod 11 on being struck by a pin 20. AThe pin 20 extends Y upwardly from a lever 21 5CV pivoted at 22 on the sinker @am .rlllgy In the operation the devicethesinkers 2 5V are moved in and out in well known manstrike theV end of lever 17 and release the rodA 11, which yis forced downfby spring r12 andf bears against member 16 to stop the machine. A
While'the'invention is shownon a machine havinga stationary vneedle cylinder, it'rnay, evidently be used on al rotary'cylinder `,ma-i. chine. It is immaterial alsowhe'ther the ers haveV merely a yarn-sinking'unction'oriav web-holding function, or` both, It will be',v
obviousy to those'fskilled in Vthe art that va-` rious other lchanges and modifications 'ofthe device maybe made without departing from' the spirit 'of the inventiomI the true i scope ,of
which is 'shown in the appended clai 1lf1s.Vl
Having thus fully described the saidinvention, what is claimed as new and desired to be secured by Letters Patent, is:
1. In a-stop mechanism for knitting machines, aV rotary element, a` vlever pivoted thereon at one end, a pivoted trip on a stationary part of the machine, an abutmentat Vthe free end of the lever and aV cam surface between the ends of the lever for engagementV by an abnormally retracted sinker to move said abutment into position to strike said trip, substantially as set forth.` Y
2. In a stop mechanism for knitting "machines, a sinker cam ring, a lever of the third class pivotedv thereonv said lever having a cam between its pivot' and its free end positioned for engagement by an abnormally retracted sinker, and means at the freeA end of the lever operative on the'driving mechanismof the machine, substantially `as set forth.'
. 3. In a stopmechanism for knitting machines, a sinker cam ring, a lever of the third Vclass pivoted thereon said lever having a cam between its Pivot and its. traced, a trip on a stationary part of the machine, and means at the free end of the lever for actuating said trip, substantially as set forth.
4. In a circular knitting machine, a series of sinkers, a sinker cam ring controlling said sinkers, a vertically movable rod adapted when moved in one direction to stop the machine, and means for restraining the rod against such movement including an element pivoted on the sinker cam ring and moved by a displaced sinker in a direction to release said rod, substantially as set forth.
` 5. In a circular knitting machine, a series of sinkers, a sinker cam ring controlling said sinkers, a vertically movable rod adapted When moved in one direction to stop the machine, and means for restraining the rod against such movement including an element mounted on the cam ring in position toA be operated by abnormally retracted sinker to release said vertically movable rod, substantially as set forth` 6.@A stopmechanism for knitting machines, comprising a series of sinkers, a sinker cam ring, a cam lever pivoted thereon, a trip device mounted when released to stop the machine, means for restraining said trip device, and means for releasing said trip device including said cam lever which is positioned for engagement by an abnormally positioned sinker, whereby it is moved, said latch released and the machine mechanism stopped, substantially as set forth.
In Witness whereof, I have hereunto set my hand at Nashville, Tennessee, this 8 day of August, nineteen hundred and twentytwo.
