UNITED STATES JOSEPH SKOWYR-A, or PALMER, Massecnirsnr'rs, assrsnon or own-HALF ro JOSEPH SLOMIAK, or WARE, raassncrrnsnrrs,
AUTOMATIC STOP FUR- SPENNIHG MACHINES AND THE LIKE.
Application filed September To all whom it may concern.
Be it known that I, J osnrrr SKowYRA, a citizen of the Republic of Poland, residing at Palmer, in the county of l-lampden and State of Massachusetts, have invented new and useful Improvements in Automatic Stops for Spinning Machines and the like, of which the following is a specification.
This invention relates to improvements in automatic stops for spinning machines and the like and has as its special object the provision of means whereby should a strand of the yarn or thread break, while being operated upon, the driving mechanism for that particular strand will be disengaged preventing entanglement and loss of material. This and other like objects are attained by the novel construction and combination of parts, hereinafter described and shown in the accompanying drawings, forming a material part of this disclosure, and in which Fig. 1 is a fragmentary top plan. view showing a portion of a spinning machine made in accordance with the invention;
Fig. 2 is an enlarged top plan view of the same;
on line 83 of Fig. 1;
Fig. 4- is a similar transverse sectional view taken on line 4. 1 of Fig. 1; and
Fig. 5 is another transverse sectional view taken in a different plane on line 55 of Fig. 3.
Throughout the several drawings, the supporting frame is indicated by the numeral 10, here shown to consist of a substantially level and flat plate having along one of its side edges brackets 11, which are used for supporting the drive shaft 12, having on it a pulley 1 1, over which is trained a belt 15, from some source of power.
On one end of the shaft 12 is a bevel gear 18, meshing with a similar gear 19, secured upon a longitudinally disposed shaft 20, carried in a plurality of brackets 21, rigidly secured upon the plate along one of its longer edges at right angle to the shaft 12.
Also carried in these brackets, above and.
to the front of the shaft 20, is another shaft 22 on which are loosely journalled rollers 23, the periphery of which are in contact with other rollers 24, freely rotatable upon the shaft 20.
Atone end of the rollers 24, are formed clutch elements 25 and engageable therewith Fig. 3 is a transverse sectional viewtaken 4, 1924. Serial No. 735,945.

33, and lower horizontal parts 3%, parallel."
with the upper portion 32, the lower elements 34; being pivoted on screws 35 fixedltothe plate 10. I
These clutch elements are normally drawn? into operative engagement by the pull of ten 7' sion springs 36, one end of which is secured, to the plate 10, and the other to the levers in a manner'clearly apparent from Fig. 2. The clutch elements .are 'held "from engagement by means later to be described. I
Fixed upon the shaft. 12 is an eccentric hub 38, to which is fitted a strap or band 39, held thereon by flanges and a screw 40'. To the opposite or front side of the eccentric band is secured a boss 41 from which projects aconnecting rod 412 pivotally engaged. at its outer end with a reciprocating bar l-l, the said bar extending longitudinally of the apparatus parallel with the shaft 20 and is guided fora reciprocating.movement in a plurality of brackets 45 fixed to the table 10.
Fixed upon the side-of the bar 1 1, adjacent to the rollers 24: and spaced in accordance therewith, are projections 46 carrying pivoted arms l? having hook like extremities 48 adapted to overlie and to rest over the thread or yarn 50 being drawn through the rollers 23 and 2 1, so as to guide the same and cause it to be distributed uniformly between the said rollers 23 and 24.
I Also formed with the arms 48 are downturned projections 51 adapted to engage, I
when the arms are allowed to fall by a loose yarn, with extensions 53, formed with the vertical arms 33 of the lever 3A so as to press the same toward the shaft 12 which motion obviously disconnects the clutches and causes cessation of rotation of the pair of rollers 20 and 22 corresponding with the particular arms 47 which may be in contact.
The bar as is reciprocated back and forth by a rotation of the driving shaft 12 and eccentric 38 and the arms 4L7 are normally held in the position shown in Fig. 5 by the unbroken yarn 50, in which position of the arms the projections 51 thereof will not engage the extension 53 of the lever 34. Should the yarn 50 break. or become sulficiently loose, the arm at? Will drop so that the projection 51 Will engage the extension and move the lever 34 to disengage the clutch as aforesaid.
In order to hold the clutches disengaged, spring detents 55 secured to the plate 10 contact with the levers so as to hold the clutches in a disengaged position until the operator shall have mended the broken strand of yarnflvhich permitted the arm ll" to drop, raise the detent and manually press the clutches again into engagement.
From the foregoing it Will be readily understood-that any desired number of the rollers between which the threads are drawn are controlled in their operation by a single reciprocating bar as so that should'aiiy individual strand become b ro en the particular set of rollers Will become disengaged from further operation and until the mechanism has been reset by the operator and Without t attesting the reiiiaining strands, thereby preventing a Waste of yarn in an obvious I manner.
mounted thereabove the peripheries of each. pair being 111 intimate cont-act, clutch ole-j shaft, thread carriers engaged With said bar, and ineanscombined With said thread carriers adapted to disengage said clutches upon'the breaking off the thread leading to the rollers with which they are engaged, 111 a spinnii'ig machine, the combination with a horizontal shaft, one or more thread carrying rollers rotatable thereon, clutch elenients :forn'ied at one end of said rollers. other clutch elements slidably keyed to said s'halt, levers operatively engaged with said keye'dclutcli" elements, means for normally holding said levers in positionto maintain.
said clutch elements in engagen'ient, a bar mounted slidably parallel to said shaft, 'means for actuating said bar reciprocatively, thread carriers engaged with said bar, one for each of said rollers, an'd neans operative coincident upon the breaking of a thread adapted to make Contact with saidlevers, whereby said clutch elements are disengaged.
In testimony whereof I have affixed my signature.
