CAP-SPINNING DEVICE.

Application filed January 22. 1914. Serial No. 813,796.

To all to 7mm it may concern Be it known that I, Vicron Biimnenn, citizen of the United States, and resident of Marshfield, county of Plymouth, State of Massachusetts, have invented certain new and useful Improvements in Cap-Spinning Devices, of which the following is a specification.

This invention relates to the spinning or twisting of textile fiber and is in the nature of an improvement upon my invention set forth in United States Letters PatentNo. 1,020,179, dated March 12, 1912.

The present improvements are intended, first, to provide an efficient means for adequately controlling the tension or ballooning of the revolving yarn, during the spinning operation, and second to provide an arrangement by which disturbances in the relationship of the cap to its external bearing member may be prevented when the cap is used on very loose spindles having considerable freedom of movement in its foot-step bearing.

The characteristic and novel feature of the present invention consists in the use of a loose yarn-engaging member so arranged as to revolve a fewer number of turns than does the cap itself, so as to retard the yarn in its revolution around the spindle and reduce the ballooning thereof. The second feature of the invention consists in the provision made for mounting the support, which carries the external bearing wheel, in such a manner that it freely accommodates itself to the oscillations of the spindle, so that the bearing wheel follows the spindle as it leans away from the bearing wheel and yields to the movement of the spindle toward the bearing wheel. Another feature of the invention consists in the arrangement of a pair of internal bearing wheels in such a position as to sustain the pressure of the spindle when it is moved inwardly by the pull of the driving band, while at the same time preventing excessive lateral oscillation of the spindle member.

Tn the accon'ipanying drawings 1 have illustrated some of the modes of embodying the principles of this invention.

F 1g. 5 is a plan view of the yarn-retard- 1ng flier; and

Fig. 6 is a plan view showing the arrangement whereby bearing wheels are used to sustain the cap.

In the practice of the invention, as illustrated in Fig. 1, the spindle member a is of any suitable construction, such as is disclosed in my aforesaid patent, and on it is mounted the inverted cup or cap member 5 which, as shown in this case, is coupled to an internal bushing or sleeve Z), whose lower conical end is passed through a central opening 6 at the top of the cap, and is clamped therein by means of the clamping nut 5 a washer of felt or other non-vibratory material being interposed to lessen the transmission of vibration and prevent undue rigidity. The external bearing wheel 0 is of any suitable contruction but preferably comprises the supporting spindle c and the enlarged flanged head presenting an annular bearing face 0 of felt or other non-vibratory material, to afford a lateral support for the cap, the flange c acting to sustain the downward thrust or weight of the cap. A suitable bearing bolster (Z is provided to rotatably support the cap, and said bearing member is provided with a diagonally extended supporting arm d which is mounted on the traverse rail 6, and whose upper surface is inclined at an angle of say approximately forty-five degrees, so that the weight of the bolster and the hearing wheel tends to cause the bearing wheel to move toward the spindle member, while allowing the bearing wheel and its support to move in the opposite direction as the spindle sways toward the rear.

The traverse rail 6 is shown as mounted on wedge-shaped blocks 6', carried by the crosshead 6 mounted on the lifting or traverse rods 6 so that the traverse motion is imparted to the cap through the bearing wheel and the rail. The supporting arm (Z of the bolster is slotted in a forward and aft direction to receive a guide block (Z which is secured to the rail opposite each spindle, and a retaining screw (Z and washer (Z serve to keep the arm cl securely in position, while allowing it to slip to and fro. To exclude lint or foreign matter, a short metal hood or cap (Z is detachably secured over the arm d by means of the retaining screw (Z It will be seen that the bearing wheel, under the influence of gravity, automatically presses lightly toward the cap while being free to movebacl: as the cap moves rearwardly or inwardly, so that a vertical constant-pressure engagement is maintained between the cap member and its external bearing.

Since the cap is preferably rotated at the same speed as the spindle member, through the spline engagement with the spindle member, there is a tendency particularly on the coarser counts of yarn to excessive ballooning, which would necessitate the use of separator plates or else a wider spacing of the spindles. In the device shown in my former patent, I use a fixed serrated ring mounted on the rail inside the lower end of the cap to retard the yarn; but in this case I dispense entirely with said ring and emplo; in combination with the cap, a rotary tension member so constructed as to engage the yarn and rotate fewer revolutions than the cap, whereby the revolutions of the yarn, through the bobbin mei her, are retarded so as to produce an increased tension on the yarn and a reduction of the ballooning. In the present case 1 use two quite differently constructed yarn-engaging tension members one of which comprises a loose annular member f, which according to the form shown in Fig. 1, is made of a metallic ring lined with felt or equivalent material to form a good frictional engagement with the exterior of the cap and acting also to somewhat cushion the bearing engagement be tween the tension member and the cap. This loose ring rests upon a small external lip or flange 5 at the lower end of the cap, and is held in place by a removable keeper ring Z9 which is sprung into a shallow annular groove formed on the periphery of the cap, so that it may be removed in order to permit the removal and replacement of the tension member. As shown, the tension member f 7'" has an internal diameter somewhat greater than the external diameter of that portion of the cap which it surrounds, so that there will be produced a differential rotation of the tension member in relation to the cap. The tension member has practically a rolling engagement with the cap, being pressed against one side of the cap by the lateral face 0 of the bearing member; and obviously the greater the difference be tween the internal diameter of the tension member and the external diameter of the cap, the greater will be the difierence be tween the. number of revolutions of the cap and of the tension member. The yarnengaging surface of the ring 7 is smooth, so that the yarn may have a circumferential slip on the exterior of the rin 7 When spinning very'fine counts of yarn, the tension produced by the differential rotation of the yarn-engaging member 7 is 'quite sufficient for practical purposes. On

the medium and coarse counts of yarn, however, the tension produced by the differential revolutions of the member 7 does not, at high speed, sufficiently reduce the ballooning of the yarn and I therefore, supplement or increase the retarding action by the use of an additional yarn-engaging tension member, which is constructed on the principle of a propeller. This supplemental tension member is a sort of winged flier comprising a central hub or perforated portion 9, pro-V vided with outwardly extending arms 9 which engage the yarn and which may themselves be turned at a greater or less angle to the horizontal plane so that they form retarding vanes which act, through the resistance of the air, to hold back or retard the revolving yarn in relation to the cap, so as produce a still greater tension on the ballooning yarn. The degree of this retardation may be varied by varying the surface area or the angle of the vanes g.

In Fig. 6, I have shown the flanged bearing wheel 0 set to one side of the direct backward line from the axis of the spindle men her, and supplemented by a supplemental bearing wheel 0 arranged on the opposite side of the center, so that as the turning band pulls the spindle member rearwardly,

the cap is sustained laterally at two points a.

suflicient distance apart to prevent lateral oscillation. The two pivot wheels 0 0 may he supported in a common bolster (2 having an inclined rearward extension (Z resting on the rail 6, as in the case of the form illustrated in Figs. 1 and 2.

in spinning the coarse counts' of yarn, where there is a tendency to bigger ballooniig than in fine yarn and where greater tension is needed to afford the desired strength to the yarn, I may use in lieu of the flier member a notched retarding ring it which is interposed between a series of loose antifriction washers h of fiber or other suitable material, which are laterally engaged by the bearing wheel 0 which is grooved to receive the larger tension ring it, as illus- V iso 7 and reducing the ballooning. The contact between the ring it and the bearing wheel 0 is very slight but is sutlicient to keep the ring concentric, so as to produce a rolling contact between the ring and the cap. Ordinarily I use this form of yarn-control only for coarser counts of yarn, while I prefer to use the flier control 51 for the medium counts of yarn, although the latter may be used for the coarser counts as Well.

The use of the term inverted cup or cap as applied to the cop-building member is intended to indicate the fact that the open end of the cap is at the bottom, its lower edge forming a frictional engagement with the yarn, while allowing the yarn to slip circumferentially thereon. This inverted arrangement is one feature that vitally distinguishes cap spinning from that species of ring and traveler spinning in which a traveler ring, generally of tubular form, is mounted around the spindle with its open end upward to assist or modify the action of the traveler in which case the traveler is an absolutely essential element for holding the yarn down adjacent to the traveler ring,

whether said traveler ring or race-member rotates or remains at rest.

What I claim is:

1. In a cap-spinning device the combination with a rotary spindle member of a surrounding rotary inverted cop-building cap whose upper end is operatively connected with the spindle for the purpose of rotating the cap, and a loose yarn-engaging tension member rotating at a slower rate than does the cap, in order to reduce the ballooning and control the tension of the yarn, substantially as described.

2. The combination with a rotary inverted cap mounted on and driven by its central driving spindle, of a loose yarn-engaging ring supported by the cap and rotating at relatively fewer revolutions than does the cap, in order to retard the revolving yarn and increase the tension thereof.

3. The combination with the rotary cap and its external bearing wheel of a loose yarn-engaging member encircling the cap and interposed between the bearing wheel and the cap, whereby the cap and the yarnengaging member are rotated at different speeds in order to control the tension on the yarn.

4:. In a cap spinning device, the combination with a rotary spindle member and a cop-building cap mounted thereon, and driven thereby, a yarn-engaging and retarding member loosely mounted upon said cap and formed with air-resisting portions to retard its rotation relative to the rotation of the cap whereby said yarn-engaging member is caused to retard the revolving yarn and reduce its ballooning, substantially as described.

5. The combination of the rotary spindle member, a rotary cop-building cap and a revolving yarn-engaging member resting loosely on the cap and provided with vanes to retard its revolution with the cap, substantially as described.

6. The combination with the rotary spindle member of a cap mounted thereon and rotated thereby and means loosely supported on said cap to retard the revolution of the yarn, substantially as described.

7. The combination of the rotary spindle member and the rotary cap of loose yarnengaging tension members supported respectively at the top and bottom portions of the cap to engage the yarn and increase the tension thereof, substantially as described.

8. The combination of the rotary spindle member, the rotary cap mounted thereon, an external bearing wheel forming a lateral support for the cap and a bearing bolster for supporting said bearing wheel, said bolster being automatically movable toward and away from the axis of the cap, in order to accommodate itself to the swaying movement of the spindle, substantially as described.

9. The combination with the rotary spindle member and its rotary cap of an external bearing wheel forming an external support for said cap and a ravity-actuated movable bolster forming a bearing for said wheel, in order to permit the bearing wheel to accommodate itself to the lateral movements of the cap and of the spindle, substantially as described.

10. The combination of a rotary spindle, a yarn-engaging cap loosely mounted thereon and driven thereby, an external traverse member arranged to support the rotating cap in order to impart a cop-building traverse thereto, said traverse member bein reciprocated at a slight angle to the normal axis of the spindle to gradually lessen the distance between the spindle axis and the traverse member as the cap is raised to progressively higher levels in building the cop, substantially as described.

11. The combination of the rotary spindle, the rotary reciprocatory cap, an externalbearing member arranged to have supporting engagement with the cap in order to impart a cop-building traverse thereto, means for gradually advancing the bearing member nearer to the axis of the spindle while the cap is building the upper portions of the cop, substantially as described.
