A TTORNEY5- Patented Feb. 8, 1938 UNITED STATES PATENT OFFICE FINE SPINNING FRAME v Etsuro Kato, Meguro-ku, Tokyo-shi, Japan Application August 19, 1936, Serial No. 96,884-
In Japan October 1 Claim.
This invention relates to certain improvements in fine spinning frame of the type in which a sliver moves vertically in the direction of the axis of a spindle disposed in a vertical position.
One object of the invention is to provide a simple and compact Another object of variation of tension spinning frame. the invention is to make the of winding yarn due to ballooning independent of the elapsed time after the dofiing of cop.
In the accompanying drawing:
Fig. 1 is a side view of a fine spinning frame embodying the invention.
Fig. 2 is a front view of the spinning frame partly broken away.
Fig. 3 is a diagram of operating characteristic curve illustrating the relation of revolving speedof spindle and elapsed time after dofling of cop in fine spinning fra Referring to Figs.
me embodying the invention. 1 and 2, I represents a gear case, 6 a poker arm which is movably mounted on a shaft 1. One end of said poker arm is operatively connected with a cam (not shown) in the gear case I by means of a connecting link 2. A
means of a connecting link 6 poker arm 4 and a number of the other poker arms 4' are arranged in a line nearly below the center line of the machine frame ll) supporting the driving electric motors 9 individual to the spindle and 4' is provided s 8. Each of the poker arms 4 n its free end with a roller 13 adapted to engage with the lower end of a vertical rod. M which exten machine frame ill. by the roller stand ds through the beams of the The vertical rod I4 is guided l1 and a lower tie beam l8 of the machine frame l0, through which said rod extends.
To the vertical rods M are secured the beams l for carrying ring rails l2, l2 and another beam I6 for carrying guide rails II, II,
' and consequently said vertical rods and these ring rails and guide rails will be moved as one unit when the poker arms 4 and 4 are moved.
From the foregoing, it will be seen that the arrangements are considerably simplified. Further, it is apparent that the guide rail H and the ring rail I! are between them, any relative made, and that the sliver is moved with a fixed distance motion not being moved vertically in the direction of the axis of the spindle disposed in vertical position,
and consequently yarn will be drafted in a vertical direction in the sliver and uide, so that a constant tension of yarn may be ensured irrespective of the motion of the guide moved with the ring rail. The fact that there is no relative motion between the guide rail ll 5 and ring rail I 2 upon their movement will result that variation of the tension of yarn due to ballooning is independent of the elapsed time after dofling of the cop.
In fine spinning frames heretofore in use, the guide and spindle are positioned in afixed relation, and the cop building is effected by up-and-down motion of the ring rail, and accordingly in the beginning of the cop building and distance between the guide and traveller is larger and the balloon- 15 ing will increase, whereby yarn will be caused to more frequently be broken, as yarn is more frequently caused to fo-ul the separator and other parts due to increase in the tension of the 'yarn.
In order to avoid this disadvantage, the revolving speed of the spindle must be lowered. On the contrary, toward the end'of the cop building the distance between the guide and traveller is smaller and the size of the balloon will decrease, so that yarn is likely to be broken by a small shock, and accordingly the revolving speed must also be lowered to avoid the said disadvantage. With fine spinning frames heretofore in use, therefore the .number of revolutions per minute of the spindle should be related to the elapsed time after the dofiing of the cop so that the control of operation of the spindles becomes more troublesome and the arrangement becomes more complicated. With the fine spinning frame embodying the invention, the guide and ring rail are related so as to be moved keeping a fixed distance between them, whereby the disadvantage of lowering revolving speed of spindle as mentioned above will be avoided, and the variation of tension of yarn due to ballooning is regular from the beginning to the end of winding of cop and independent of elapsed time after the dofling of cop as illustrated by a diagram in Fig. 3.
As Seen' from the foregoing description, with the arrangement according to the invention, the drafting tension of yarn is constant irrespective of up-and-down motion of the guide moving with the ring rail, as the direction of drafting yarn in sliver and guide is vertical due to sliver being moved vertically in the direction of the axis of and guide rail are securely mounted on the vertical rod which is moved up and down for cop building. Still further the size of the spinning frame may be made smaller, as the space between two sides of the machine frame may be decreased due to the vertical rod being disposed in an intermediate position between the spindles arranged on two sides oft-he machine frame, an asmooth operation of the vertical rod may be n'sured due to the guiding function provided by the tie beam forming part of themachine frame through which the vertical rod extends.
Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I claim: i
A fine spinning frame comprising, in combination, a frame, two parallel rows of vertical spindles arranged on opposite sides of the frame, two parallel rows of drafting apparatus arranged on opposite sides of the frame ,and comprising parallel rows of vertically arranged drafting rollers to draft slivers vertically in substantial c0- axial relation to said spindles, vertically slideable rods mounted in the frame and disposed intermediate the rows of spindles, ring rails and guide rails secured in spaced apart relation on said vertical rods, actuating means operably connected to said rods for simultaneously moving said rods vertically, and individual motor driving means for each of the spindles.
