4 Claims.
This invention relates to a spinning' machine for the production of artificial fibers, particularly of the type in which the filaments are collected within a centrifugal bucket. The invention particularly relates to an improved traverse mechanism for reciprocating the funnels which serve to guide the. filaments and control the winding thereof within the buckets.
It is an object of. the present invention to provide a traverse mechanism which is of simple construction and requires a, minimum of space in the spinning machine. A further object is to provide the form of traverse mechanism which avoids transfer of power by means of torsion and utilizes instead a linkage system in which compressive and tensile stresses are utilized and developed. A further object of the invention is to arrange the mechanism in a housing extending longitudinally of the machine at the same level as the spinning buckets, between the rows of buckets disposed on opposite sides of the machine so that all of the mechanism except for a projecting portion of the supporting posts which actually carry thefunnel-supporting rails, is positioned below the upper level of the spinning bucket chambers. This arrangement provides compactness and facile rotection from corrosion.
The traverse mechanism of the presentinvention is capable of operation at high speeds with a minimum of shock and vibration, at the ends of the traverse stroke Where reversal of direction must occur. This characteristic is the direct result of the particular construction, especially because of the elimination of torsion and the virtual elimination of cam surfaces. Other advantages, objects and features of the invention will be apparent from the drawing and the description thereof hereinafter.
As shown in the drawing- Figure 1 is an end view in cross-section of the lower central portion of a spinning machine incorporating the present invention;
Figure 2 is a longitudinal cross-section in elevation; and
Figure 3 is a fragmentary view similar to Figure 2, showing a modification.
As shown in the drawing, the lower central portion of the spinning machine comprises an essentially symmetrical arrangement of two longitudinal spinning baths 2, two rows of spinning buckets 3 extending longitudinally of the machine and arranged to be driven by motors 4. The machine is divided into longitudinal sections and in Anni. Mi-in Hum is nrnviflnfl an intermediate brackets 6 for supporting the motors. Two ver-' tical sleeves 1 are secured to the top of each casing and extend a short distance into it, aswell as upwardly from it. Longitudinal angle irons 8 are provided above the casing and bear against a shoulder 9 on each of the sleeves to give additional support thereto. Longitudinal angle irons are provided on each side of the sleeves and support the'framework II which may be leaded and provided with cylindrical nestings I2, one for each spinning bucket within the spinning bucket chambers l3 which extend longitudinally of the machine. A' channel or duct l4 extends above the casings 5 the full length of the machine and has a cover l5 provided with upwardly extending pipes or tubes [6 concentric with the sleeves I. A blower I1 is provided to conduct fresh air or other inert gas through a suitable connection l8 into the duct M for reasons which will be hereinafter explained.
A cylindrical post I9 is reciprocably mounted within each sleeve 1 and carries a corrosionresistant cap or hood having a skirt 2| of a length approximately equal to the height of the piping l6 and approximately equal to the trafunnel brackets 23 which may be of conventional verse stroke which depends upon the depth of the spinning bucket. A rail 22 is supported on each side of the two caps 20 for carrying the construction for a given section of the machine. Funnel guides 24 are shown carried by the brackets 23. Means 25 may be provided for conducting oil to the upper regions of the bearings between cylinder l9 and sleeve 1. The lower end of each post I9 carries a yoke ZBhaving a transverse guideway 21 which receives a cooperating block 28 pivotally connected between the ends of one arm of a pair of parallel bell crank levers 29. A pin 30 extending across the casing acts as a fulcrum for the bell crank levers and a pin 3| connects the other ends thereof to a reciprocable rail comprising two parallel straps or rods 32 connected by transverse reinforcing ribs 33. The post [9 in each section of the machine is similarly connected through bell crank levers to the rail 32 except that in every other section the bell crank levers are connected to the rail on opposite sides of the post I9, so that the posts in half of the sections will be traveling upwardly, while those in the other half will be traveling downwardly, thereby balancing weights.
A reciprocating motion may be imparted to one of the posts l9 by means of a connecting rod 34, which may be reciprocated in any suitable mancally represented by means of the piston 35 connected to the rod 34 and operating within 9. cylinder 38 to the opposite ends of which the fluid medium (such as in any suitable liquid) may be alternately supplied by means of channels 31 and 38, respectively. If desired, the rod 34 may be provided with roller followers 39 at its foot for co-operation with a suitable cam 40. Instead of having the connecting rod 34 pushing up directly on one of the posts 19, it ma be arranged to push longitudinally on the rail comprising the rods 32. Regardless of how the driving force is imparted to any, one of the .bell crank levers, such as that at the extreme left of Figure 2, the same motion is applied to corresponding posts in alternate sections of the machine, the opposite direction of motion beingimparted to the posts in the intervening sections of the machine. This transfer of motion does not involve any torsion, being entirely transmitted by compressive and tensile stresses exerted upon the rail 32 as in the bell crank lever 29. c
The hoods 20 and the associated pipes I6 cooperate withthe forcing of air through the duct ll to preventthe admission of foul air such as acid fumes from .the vicinity of the spinning bath into the bearings for the reciprocable posts and into the other working parts housed below the upper level of the spinning compartments.
Thus, the invention provides a compact, simple corrosion-protected, substantially vibrationless, high speed traverse mechanism.
It is to be understood that changes and variations may be made without departing from the spirit and scope of the appended claims.
