The present invention relates to spinning buckets such as those used in the manufacture of rayon.
It is the present practice in the manufacture of rayon to remove the spinning bucket in which a cake of spun rayon has been formed entirely from the driving shaft on which it is mounted in order to remove the cake. To facilitate manufacturing,it is necessary that the buckets be so mounted on the shaft that they can be quickly and easily removed. The usual methods now employed are either to slide the bucket over the end of the shaft using only .a tight fit or to use a rubber ring between the bucket and the shaft. It has been found that there is considerable slippage between the buckets and the shafts, es-
' pecially when starting and stopping. This slipping tends to wear the connection as does the constant removal and replacement of the buckets. The wearing of the connecting parts between the bucket and the shaft is an accumulating evil as the more the parts wear, the greater is their tendency to wear. As the connection between the buckets and shaft becomes loose. vibration is set up in the shaft. This vibration is transmitted down the shaft to the driving means and there likewise causes a considerable wearing of parts. As the buckets are driven at a high speed, often around 9000 R. P. M., the necessity of a tight connection between the bucket and the shaft is of prime import-ance. It is therefore necessary to replace parts quite frequently and at considerable cost to the manufacturer.
The object of the present invention is to provide a means whereby the above referred to disadvantages are overcome.
In the drawing, Fig. 1 is a cross sectional view of van embodiment of the invention; Fig. 2 shows a portion of Fig. J. having an auxiliary part in place; Fig. 3 is a perspective view of .a modification, and Fig. 4 is a View of a further modification.
Referring to Fig. 1 of the drawing, 5 indicates a bucket made of acid resisting material, such as artificial resin. The bucket 5 is mounted on a driving shaft 6, which may be driven by ,an electric motor or other suitable means. The motive means for driving the shaft 6 is not shown.
A pin 'I is provided to positively connect the shaft 6 to the bucket 5. The pin I passes through an opening 8 in the bottom of the bucket 5 and screws into a threaded opening 9 in the top of the shaft. Formed integral with the pin I just above the threaded portion, is a nut of the bucket 5.

A false bottom I comprising a thin circular disk rests bucket 5.
with
made of the same material as the bucket on a shoulder I6 in the bottom of the To effect turning of the false bottom the bucket, the pin 'I extends upward through an elongated opening II in the false bottom until fiush with the top of the false bottom.
Two fingers I8a formed integral with the top of the pin extend outward from opposite sides of the pin and fit inthe opening I'I. cover I8 is provided for the bucket which modate the hook 24 of the lifting device 2l.
though one opening 25 is all that is needed, two radially opposite ones are provided to maintain the balance of the disk. The false bottom is pulle d upward with the lifting device 2l and the rayon cake I9 is thus removed from the bucket 5.
The that ease.
inside of the bucket is highly polished so the cake can be removed with comparative Two modifications of the lifting device are shown in Figs. 3 and 4. The lifting device 26 shown in Fig 3 comprises a handle 2'I, a shaft 28 and three arms 29 which extend outward 120 apart from the bottom of the shaft 28.
On the end of each arm is a right angle finger 30. In order to accommodate these ngers, the false bottom is provided with three right angle slots The fingers 30 are inserted in the slots 3| and then the whole lifting device is given a slight twist. This shifts the fingers so that they will bear against the under side of the false bottom when an upward force is exerted on the lifting device. In this modification an opening in disk I5 corresponding to opening I.'I in Figs. 1 and 2 -is omitted as the upper end of the pin which interlocks with the bottom I5 may be omitted if desired.
The modification of the lifting device shown in Fig. 4 comprises a handle 32,l a shaft 33 and a rubber suction cup 34. With this device no holes are necessary in the false bottom. 'I'he suction cup is pressed against vthe bottom until a suction is formed in the cup. 'Ihe handle is then moved upward, pulling the false bottom and silk cake with it.
When the bucket 5 is being installed, the shaft 5 is fitted in the opening of the sleeve I2. The pin I is insertedthrough the opening 8 in the bottom of the bucket 5 and screwed into the threaded opening 9 in the top of the shaft 5. As the end of the shaft 6 and the opening in the sleeve I2 are both beveled, the pin 'I is screwed down until the nut I0 pulls the bucket 5 down far enough to provide a tight fit between the shaft 6 and the sleeve I2. The bucket 5 and the shaft 6 are now positively connected and no slippage can take place. The false bottom is then placed in position resting on the shoulder I6 in the bottom of the bucket and the ngers i8a, in the elongated slot I'I. The cover i8 is placed in position and held there by the rubber ring 20.
The bucket 5 is now ready for use and a cake of rayon is spun in the busket between the false bottom and the cover. When the cake is completely spun to the required size, the machine is stopped and the cover is removed. The lifting device 2i is inserted in one of the slots 25 and is moved edgewise to bring hook shaped end 24 beneath the bottom, pins 24a resting on top of theV bottom. The false bottom I5 is then pulled upward, thus removing the rayon cake. A new false bottom is placed in the bottom of the bucket and the cover replaced. The bucket is new ready to be used again.
As can be seen from the above description, there is no need to remove the bucket from the shaft after it has been once installed. This eliminates all chances for the bucket to werk loose on the shaft and cause wearing or vibration. Also to remove just the cake is much less cumbersome than removing the bucket as is done at present.
'Ihe improved arrangement has several advantages over the old arrangements. Due to the positive connection begveen the shaft and 'the bucket, wear and vibration are eliminated and the number and cost replacement parts; is
greatly reduced. Since the bucket is fastened directly to the shaft and the same bucket is used repeatedly, the number of bucketsit is necessary to have on hand is greatly reduced, thus reducing the capital investment. 'I'he positiveconnection between the bucket and the shaft also permits the bucket to be driven at a higher speed than is permissible using the old method. This is particularly desirable to the manufacturers of rayon as a much finer silk is spun at higher speeds.
What I claim as new and desire to secure by Letters Patent of the United States is:
1. A spinning spindle comprising a driven shaft,
a spinning bucket, means for positively fastening the bucket tcthe shaft', and a removable false bottom adapted to t in said bucket for removing the cake which forms on the side walls of the bucket without disconnecting the bucket from the shaft.
