UNITED STATES PATENT QFFICE.
HARRY JOHN ELEY, 0F SUTTON COLDFIELD, BIRMINGHAM, ENGLAND.
CENTRIFUGAL APPARATUS FOR SPINNING ARTIFICIAL SILK AND VISGOSE.
Application filed April 19, 1927, Serial No. 184,979, and in Great Britain March 15, 1926.
These improvements have more particularly to do with the method of mounting the spinning box and arranging the rotor.
According to this invention the spinning box or Centrifuge can be mounted directly on the end of the motor shaft (or a shaft driven from the motor) and driven at the required speeds without any appreciable or detrimental oscillation. v
The s inning box and the rotor shaft are arrange in such a manner that the spinning box itself is free to adjust itself so that there is no undue vibration even whilst coming up to speed or at the required speeds.
In addition, the spindle and spinning box are arranged so as to facilitate the withdrawal and replacement of the box under the abnormal conditions obtaining in practice.
The invention consists more particularly of an original design of spinning boxtogether with an original design of rotor spindle.
The spinning box is designed in such a manner that the centre of gravity is low to permit the box to sit freely on the end of the shaft. The drive. is taken from a pin across the top of a dome engaging in a slot on the domed end of the rotor shaft so that the box is free to" adjust itself and thus come up freely and rotate freely about the true axis of spin.
The rotor is free to oscillate in any direc tion and its shaft may be vertical or it may drive a vertical shaft in which case it may be at right angles to the shaft axis.-
I will now describe my invention with reference to the accompanying drawing, which shows a construction in which the spinning box is mounted on the vertical extension of a rotor spindle. The drawing is largely in section.
The base plate 1 supports the rotor 2 through the intermediary of a thrust ball bearing 3 and ring bearing 4 over which is a dust cover 5. The spindle 6 of the rotor isextended and carries a partly spherical head 7 on which the spinning cup 8 rests in ball and socket,fashion. A slot 9 is made across the head 7 and receives a pin 10 from the underside of the cup and by which rotation of the spindle is communicated to the cup Without impairing the ball and socket movement.
The spindle 6 passes through a floating bearing 11 carried on a cylindrical bracket 12 by. blade springs 13.
This bracket is shown with an opening through which the spindle, rotor, and its bearings can be lifted when the cover 14 is released. This permits easy replacement of parts.
The cup 8 has a low centre of gravity and can be simply lifted off and replacedasrequired. The connection between the spindle and the cup is such that the latter is free to incline in any direction but will rotate with the spindle and will vertically adjust itself even as the spindle comes up to speed; in addition to which vibrations in the spindle are largely damped out by the free relative, other than rotary, movements of the spindle and the cup.
What I claim is 1. In centrifugal apparatus'for, spinning artificial silk and viscose, a cup mounted on a spindle in ball and socket manner with a slot and pin for conveying the rotation of the shaft to the cup.
2. Centrifugal apparatus for spinning artificial silk and viscose according to claim 1, in which the spindle is an integral extension oflthat of a rotor the axis of which is vertica 3. Centrifugal apparatus for spinning artificial silk and viscose in which a cup is mounted on the 'ball or dome-shaped end of a vertical shaft and is rotatably connected thereto in pin and slot manner but has otherwise free relative movement.
4. Centrifugal apparatus for spinning artificial silk comprising in combination a cup,
having a rounded socket on its under side, a pin extending across the socket, a vertical spindle under the cup and furnished with a rounded end to enter the socket, saidrounded end having a slot to engage the pin in the socket.
5. Centrifugal apparatus for spinning artificial silk comprisinga base, a bearing in the base, an electric motor supported on its vertical spindle by the said bearing, an exrounded end, a cup above the rounded end tension of the said spindle above the motor, and having a rounded socket on its under a bearing enclosing the said extension, resilside and fitting overthe rounded end of the 1 ient means supporting this hearing in a spindle With a pin across the socket engag- 5 bracket, a further extension of the spindle ing in the slot.
above the bracket, a rounded upper end to In testimony whereof I aflix my signature. the said further extension, a slot across the HARRY JOHN ELEY.
