- INVENTOR. WILLIAM PRINCE'SMITH BY MM ATTORNEY Patented June 29, 1937 SPINDLE FOR RING SPINNING AND LIKE MACHINES William Prince-Smith, Keighlcy, England Application October 29, 1936, Serial No. 108,290

In Great Britain April 17, 1936 3 Claims.

centering the spindles with respect to the rings whenever the spindles are replaced after having been removed from the spindle rail for the cleansing of the working parts from oil residue or dirt; another object of the invention being to avoid undue wear of the spindles and/or their bearings by the application of braking pressure.

In ring spinning machines in which the spindles are mounted in solid bolsters it is necessary to remove the spindles from the rail for cleansing purposes and when replacing the spindles in the rail it is a diiiicult matter for an overlooker to set them true with respect to the rings, as a consequence of which the cleansing is frequently neglected.

Again, the braking of the spindles, either by raising them axially by applying pressure against the lower sides of the bottom flanges of the whorl to force one or other flange of the whorl against a fixed abutment, or by applying lateral pressure to the bottom flange of the wharle, tends, in the one case, to lift the running point of a spindle from its seat and consequently to damage the spindle point, and, in the other case, to cause undue wear of the upper annular bearing of a spindle.

Both these disadvantages are overcome by the present invention, to which end a spindle unit for ring spinning and like machines is positioned and supported by accommodating the bolster freely in a centrically adjustable bush secured to the spindle rail, and means are provided whereby, when it is desired to apply braking pressure to the spindle,the spindle unit is moved bodily axially within said bush in order to bring a rotary part of the unit into contact with a fixed abutment. The construction and arrangement are such that the spindle unit can be withdrawn bodily from the aforesaid bush and replaced therein without disturbing the correct setting of the spindle.

One constructional embodiment of the invention is illustrated by way of examlpe in the accompanying drawings wherein, Figure 1 is a side 5 view partly in section, of a spindle unit, Figure 2 is a vertical section of the unit, Figure 3 is a detail view, in sectional plan, of part of the unit below the level of the bottom flange of the whorl, the spindle rail and the parts located below it 55 being omitted, and Figure 4 is a front elevation of the spindle unit, the spindle rail being shown in section.

I is the apertured spindle rail in which is carried a bush 2 having slight clearance (for the purpose of centering the bush with respect to the corresponding ring on the ring rail, not shewn), the lower end of the bush being screwthreaded to receive a nut 3 whereby the bush 2 is fixed or, clamped in position in the rail I.

About a reduced neck integral with the nut 3, a bracket 4 is secured by means of a set screw 5, to which bracket a. lever 6, is pivoted at 6A and is formed with a rounded nose GB.

I is the whorl whereof the lower flange is located below a leather pad 8 carried by an abutment member 9 formed with a knob Ill and carried slidably by a screwed stem ll taking into the head of the bush 2,-a tension spring I! being confined between a shoulder within the base or body of said slidable abutment member 9 and the head of the stem II, and the forward lower part of the body of the abutment member being formed integrally with a projection I3 fitting int a corresponding recess I4 in the head of the bush 2.

I5 is the bolster which fits with sufilcient clearance to enable it to slide axially within the bush 2.

I6 is the spindle blade, I1 the swivel inner sock and I8 the damping spring, all of which parts are of known construction.

I9 is a pin projection from the upper part of the bolster l5 and which is receivable in a slot formed in the upper edge of the bush 2 and which serves to locate the bolster in respect thereto.

It will be observed that by constructing the spindle unit so that the bolster I5 is slidable axially in relation to the fixed and centred bush 2 carried by the spindle rail I, primarily any spindle unit can easily be removed for cleaning purposes and re-inserted without disturbing its axial adjustment with respect to its corresponding ring, and secondly, the braking of the spindle can be effected without detriment to therunning point of the spindle and without applying lateral thrust to the spindle bearing.

The braking of the spindle is caused by the application of pressure from an operatives knee against the front of the pivoted lever B whereof the rounded head 63 thereupon forces the bolster l5 axially upwards within the'bush 2 carrying with it the entire spindle unit bodily until the lower flange of the whorl I is brought into contact with thelpad l on the abutment member 9 whereby the rotation of the spindle is arrested.

This abutment member 9 serves a dual purpose in that besides its braking function itvalso prevents a spindle being lifted out of position in the event of a tightly fitting bobbin being drawn of! a spindle.

When it is desired to withdraw a spindle unit for the purpose of cleansing, or the spindle blade for the purpose of adding lubricant, the knob in of the abutment member 9 is gripped by the operative and the member I is pulled outwardly against the pressure of the spring I! until the pad I is beyond the periphery of the lower flange ot the whorl 1, whereupon the entire spindle unit can be withdrawn bodily from the bush 2 and dealt with as required.

Conversely, to replace a spindle unit, the member is slid outwardly and the unit is dropped into the bush 2 in such a position that the pin i8 falls into the slot 20, after which the member 9 is released and is returned inwardly by the spring II, the projection IS on the base or body of the member 9 making sliding contact with the upper face of the recess I4 and taking any upward thrust during both the outward and inward sliding movement 0! the member 9 and thereby avoiding upward pressure on the screwed stem II when the brake is operated.

By the herelnbefore described construction of spindle mounting, a spindle may be lifted out of position without necessitating the manipulation of any nuts or screws, cleaned, and replaced without disturbing its correct setting.

What I claim is:-

1. In ring spinning and like machines including an apertured spindle rail and an apertured ring rail, a spindle, a flanged driving whorl on said spindle, a bolster wherein said spindle rotates, a bush secured in an aperture in said spindie, said bush being adjustable centrically with respect to the corresponding aperture in said ring rail, and said bolster being slidable axially within said bush, means hinged below said spindle rail to raise said bolster axially within said bush, and a spindle-braking device including a stationary abutment member, having a resilient brakepad located in the path of axial movement of said flanged driving whorl and serving to arrest rotation of said spindle when said bolster is raised.

2. The combination with ring spinning and like machines having a spindle rail, a bush mounted therein, a bolster removably supported in said bush and a spindle whorl rotatably supported upon said bolster, 01' a brake normally extending in the path of travel of said spindle whorl for preventing the removal of said bolster from said bush and adapted at times to exert a braking action upon said spindle whorl, a support for said brake detachably connected to said bush, means [or normally retaining said support in locking engagement with said bush, and manually operable means for moving said brake out of the path of travel of said spindle whorl whereby said bolster and said spindle whorl carried thereby may be removed from said'bush.

3. The combination with ring spinning and like machines having a spindle rail, a bush adjustably mounted within said spindle rail, a locking nut for said bush, a bolster removably supported in said bush, a spindle whorl rotatably supported upon said bolster, a bracket detachably connected to said locking nut, a lever pivotally connected to said bracket and at times having engagement with said bolster for moving the latter within said bush, a brake for said spindle whorl, a support for said brake, a set screw for detachably connecting said brake support with said bush, and resilient means for normally retaining said brake within the path of travel of said spindle whorl and retaining said brake support in looking engagement with said bush.

WILLIAM PRINCE-SMITH.
