TRAVELER FOR RING-SPINNING- MACHINES.
Specification of Letters Patent.
Patented June 8, 1909.
Application filed. September 27 1907. Serial No. 394,864..
To all whom it may concern:
Be it known that we, VIOTORIEN- DAoUsT, a subject of the Kingdom of. Belgium, residing in Brussels, Rue Bollineka 15, and NIooLAs DECK, a subject of the Kingdom of Belgium, residing in Brussels, Rue Veewyde 76, have invented certain new and useful Improvements in Travelers for Ring-Spinning Frames; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked therein, which form a part of this specification.
This invention relates to travelers of the needle or transverse wire type for ring spinning frames and consists in the hereinafter described improved formation of said travelers, the object of which is to keep the length of thread between the traveler and the cop or bobbin and the tension of the same practically uniform and small for the varying diameters of the cop; in order to allow very fine and soft yarns to be spun on ring frames.
On the drawings appended hereunto, Figures 1 and 2 represent in vertical section and plan a diagrammatic View of the improved needle traveler; Figs. 3 to 12 represent several forms of construction of travelers embodying the above arrangement.
The traveler forming the subject of this invention is diagrammatically represented and consists essentially of a straight part between the points A B Fig. 1 containing at the points G and at 0 two cranks or bends having the efiect of causing the thread to pass to and from the travelers ways at the same place, and of a curved part shown in full lines Fig. 2 at B R I in which the straight part terminates. The yarn delivered by the'front drawing roller passes first into the bend at the point 0, then into the bend at the point C and finally on to the bobbin.
The traveler works in the groove formed by the ring G and the cap F fixed thereon. As the bobbin drags the traveler around,
the centrifugal force of the heavier end forces it against the outer circumference of the groove and the point of contact of the three positions A B R 1 A B R 1 and A B B I corresponding with three thicknesses of yarn wound on to the bobbin or cop. For each of these positions the letters O O 0 represent the points at which the thread from the front roller arrives at the traveler, the letters C C C,
the points where the thread leaves the traveler, the letters J J J the points where it arrives at the bobbin; the letters K K K the points of contact of the traveler with the bobbin and the letters R R R the points of contact of the traveler with the ca F.
As will be seen from the drawing, the traveler in consequence of the curvature B R displaces itself laterally as the diameter of the cop increases so that with a suitable curvature the distances J G G and J 5 C remain practically constant, and the length of thread between the cop and trav eler remains the same and short, while the distances C K C K and C K', likewise remain practically constant so that the drag of the traveler on the length thread likewise remains uniform, thus allowing very soft and fine yarns to be spun from cotton wool or silk of short length of fiber.
Eccentrically weighted travelers have been proposed before but these were made with a projection on the same bearing against the inner edge of the cap F, in consequence they could not displace themselves laterally, and the above advantage was not obtained. 7
Several forms of construction of travelers embodying the above arrangement are represented on Figs. 3 to 12.
.yarn.
The wires forming the travelers as shown in Figs. 3 to 8 are bent inward at the points 5 and 7 and then bent outward as shown forming two cranks the corners 1 and 2 of which correspond to the points 0 and C of the diagram Figs. 1 and 2, the lower ends of the wire bearing against the beads 3 and f of the cap F. In order to localize the ten sion required for obtaining a firm and hard bobbin in the end of the thread between the point C or corner 2 and the point J where it is wound on to the bobbin the thread may be lapped in the known manner around the straight upper part of the traveler between the bends 1 and 2 to produce a braking action and confine the tension of the thread to the short end J G and reduce tension of the length of thread between the traveler and the front roller to a small amount. Preferably however the travelers are formed with a further bend or loop 6 through which the thread is passed to produce this braking action, this arrangement facilitating the threading of the traveler when piecing the In order to facilitate the sliding of the yarn along the bend of the traveler and to impart to it greater stability, it is advantageous not to have its cranks 5 and 7 in the same vertical plane.
The part A B to at) of the traveler may be curved in a horizontal plane in the known manner in order to reduce the space required for its free rotation between the ring and bobbin.
The form of execution shown in Figs. 9 to 12 has the following characteristics. The arrangement of bend at the point C by which the yarn starts toward the bobbin makes the playing of the yarn easier together with a greater friction of the thread on the traveler. The point 0 where the yarn arrives is remote from the center of the bobbin which increases the eccentricity of strains produced by the tension of yarn.
The Fig. 12 shows a modified form in which the rear projection A joins to the bend R I characterizing the invention. Said arrangement increases the result of eccentricity of the device, and the traveler so arranged is more rigid and less liable to be deformed.
Claims 1. The combination with a spindle and a ring surrounding the same having an annu lar recess; of a traveler mounted in the latter comprising a straight portion extending across the ring orifice and having a threadguide formed therein and an end portion extending into the groove in contact with the wallthcreof and adapted to rock on said end portion against the vertical wall of the ring as a fulcrum for the traveler.
2. The combination with a spindle and a ring surrounding the same having an annu lar recess; of a traveler mounted in the latter. comprising a. straight portion extending across the ring orifice and having a thread guide formed therein and a curved end portion extending around the groove in a direction opposite to the direction of rotation. whereby said traveler will rock on said curved end portion as a variable fulcrum against the wall. of the ring.
3. The combination with a. spindle and a ring surrounding the same having an annular recess; of a traveler mounted in the latter, extending across the ring orifice and having two thread guides formed therein in different longitudinal vertical planes, one end of the traveler having contact with the vertical wall of the ring.
4.. The combination with a spindle and a ring surrounding the same having an ammlar recess; of a traveler having a straight portion extending across the ring orifice and having two thread guides formed therein in different longitudinal vertical planes. and an end portion curving from the orifice in a direction opposite to the direction of rotation into contact with the wall of the recess. to form a variable fulcrum against the ring.
The combination with a spindl and a ring surrounding the same having a annular recess; of a traveler having a straight and a. curved end portion. and a straight portion extending across the ring orifice and having a running on and a running oil thread guide formed therein lying in different horizontal and vertical planes from saidendportions, and a bend in the traveler between the guides engaging the thread to increase the friction thereof on the traveler between said guides.
The combination with a spinning ring having an annular recess; of a traveler extending across the orifice of the ring and having at one end a comparatively long curved portion conforming to the curvature of the ring and a curved portion of less radius between the ends of the traveler and adjacent the aforementioned curved portion, the portion of greater radius capable of frictionally engaging a wall of the groove in the ring and the curvature of less radius acting as a variable fulcrum for the traveler.
T. The combination with a grooved spinning ring; of a traveler having a substantially straight portion having a thread guide and extending across the orifice of the ring and a curved. portion intermediate its ends acting as a variable or shifting fulcrum against a wall of the groove to shift the position of the traveler and guide.
8. The combination with a grooved spinning ring and a spindle; of a traveler ha ring a substantially straight portion and, thread guide, said straight portion extending across the orifice of the ring, and on one side of the spindle, a curved portion terminating oppoas our invention, We have signed our names site the straight portion on the opposite side in presence of two subscribing wltnesses. of the spindle, said curvedportion acting as VICTORIEN DAOUST. a variable or shifting fulcrum against the NICOLAS DECK. 5 Wall of the groove to shift the position of the traveler and guide.
In testimony that We claim the foregoing Witnesses:
