BRAND IMULTANEO NG YARNS OR THREADS INT Filed Sept. 27, 1955 ET AL 2,028,644 USLY TWISTING AND O COPS W. T. APPARATUS FOR 5 WINDI Patented Jan. 21, 1936 PATENT OFFICE APPARATUS FOR SI MULTANEOUSLY TWIST- ING AND WINDING YARNS OR THREADS INTO COPS William Thomson Brand and Eric John Fairweather, Dundee, Angus, Scotland Application September 27, 1935, Serial No. 42,546 In Great Britain September 29, 1934- 4 Claims.
This invention relates to apparatus for simultaneously twisting together a plurality of yarns or threads and winding the same into a cop or the like.
Apparatus according to the invention comprises a rotary cup or cone or equivalent structure coaxial with an axially movable spindle, and rotating yarn guides, one carried by said structure and one deriving traversing movements from a cam whose axis lies on the axis of rotation of said structure, the assembly being such that a plurality of yarns or threads led through said guides to said spindle are simultaneously twisted together and built into a cop or the like.
The cam is suitably formed as a sleeve having an internal cam groove.
Fig. 1 of the accompanying drawing is a sectional elevation of apparatus according to the invention. Fig. 2 is a fragmentary elevation of the cone and reciprocating bar shown in Fig. 1. Fig. 3 is a fragmentary elevation, partly in section, of a modified form of cone and Fig. 4 is a plan view corresponding to Fig. 3.
As illustrated by Figs. 1 and 2, the yarns l (two or more) to be twisted together and wound into a cop are led from the customary final retaining or drawing roller or rollers over a tensioning device (not shown), to a guide 2 or the like attached, by means of an arm 3, to a revolving cone or cup 4 coaxial with the spindle 5 on which the cop 6 is to be formed.
Conveniently, the cone 4 is rotated by means of a spiral gear secured on a shaft 1' and meshing with a spiral gear 8 on a depending sleeve 9 forming an extension of the cone 3 and embracing the spindle 5. The spiral gear '5 also meshes with a spiral gear ll] mounted on a shaft 2| and meshing in turn with a spiral gear I! coaxial with the spindle 5 and unitary with a socket l5 within which is secured a sleeve i2 formed with an internal cam groove l3.
A bar l6 received in a groove is formed in the outer face of the cone 4 is provided with a follower which tracks the cam groove l3 whereby rotation of the sleeve l2 imparts endwise reciprocating movement to the bar l6.
!9 denotes a slot formed in the upper end of the grooved portion of the cone. 2!] denotes a yarn guide provided at the upper end of the bar 16.
In operation, the gear I drives the gear H and therefore the sleeve l2. The gear 1 drives the gear 8, the sleeve 9, and the cone 4. The cone 4 and sleeve I 2 rotate at different speeds. The cam groove [3 reciprocates vertically the bar l6 and therefore the yarn guide 2e. The yarns I pass through the guides 2 and 2t, and, having been twisted, are built on the spindle 5, the vertical movement of the bar it imparting traversing movements to the guide 20.
The spindle 5, which is not driven, is supported by a footstep bearing 22 carried by a lever (not shown) which may be actuated by the foot of the operator when it is desired to' move the spindle endwise.
During the operation of twisting the yarns and building the cop, the spindle 5 rises, the lever swinging on its fulcrum. The lever may be provided with arradjustable spring or counterweight, so that different sizes and/or qualities of yarns may be tightly wound into a cop.
Rotation of the spindle 5 is resisted by the action of a suitable drag device 23.
Preferably, the depending extension 9 of the cone 4 is mounted in ball bearings 24 located above and below the machine rail 25.
According to the embodiment of the invention illustrated by Figs. 3 and 4, there are substituted for the cone 4 three spaced conical rollers 26 which are mounted between a ring 21 and a sleeve 28 which corresponds to the lower part of the sleeve presenting the cup 4 of the embodiment shown by Figs. 1 and 2 and which is embraced by the sleeve l2. The ring 21 is supported by three spaced stay rods 29 and is provided with a yarn guide 2. The groove l8 in which reciprocates the bar I6 is formed in the outer surface of the sleeve 28. The yarns pass from the guide 2 to the guide 20 carried by the upper end of the bars l6 and are wound into a 30 cop on the spindle 5 which passes, centrally through the ring 21 and sleeve 28, the operation being similar to the operation described with reference to Figs. 1 and 2.
Any suitable stop motion device may be fitted. 3
What we claim is:-
1. Apparatus for simultaneously twisting together a plurality of yarns or threads and winding the same into acop or the like, comprising a rotary cop-receiving structure, an axially movable spindle coaxial with said structure, and rotating yarn guides, one carried by said structure, and a cam for imparting traversing movements to the other of said guides, the axis of said cam lying on the axis of rotation of said structure.
2. Apparatus as claimed in claim 1 in which the cam is formed as a sleeve having an internal cam groove.
3. Apparatus as claimed in claim 1 in which a spiral gear on a driving shaft drives a spiral gear secured to the cam, said shaft driving also a second shaft which drives the rotary structure through spiral gearing.
4. Apparatus as claimed in claim 1 in which the rotary structure is constituted by conical rollers assembled round the spindle at spaced intervals with their axes inclined to the spindle.
