' Application 10 Claims.
This invention concerns an improved spinning bucket construction adapted to facilitate the removal of cakes of yarn -or other filamentary material wound or spun therein and also a simple form of accessory adapted to cooperate with the improved spinning bucket to remove the cakes therefrom. 4
Heretofore, cakes have been' removed from spinning buckets by inverting the buckets or by the insertioninto the bucket interior of a hand tool with which a bottom plate carrying the cake was seized by means of suitable cooperating elements formed in or on the bottom plate. In ac cordance with this invention, a system-is provided which issimpler from the standpoint both of the character of accessory devices needed and of the manipulative technique needed to remove the cake from the spinning boxes.
In the drawing; illustrative of the invention, Figure 1 is an elevational cross-section view of a spinning bucket containing a cake about to be placed upon one form of accessory to removethe cake therefrom,
- Figure 2 is a view similar to Figure 1 but with the cake ejected. from the bucket,
Figure 3 is a perspective view of the bottom of a spinning bucket,
Figure 4 is an elevational cross-section view of a spinning bucket about to be placed upon another form of accessory,,
Figure 5 is a perspective showing a modified form of bucket hub,
Figure 6 is an elevation, partly in cross-sec-'.
tion showing the hub of Figure 5 cooperating with a complementary form of accessory similar to that of Figure 4, and
Figure 7 is an elevational-cross-section view showing the cake ejected from a spinning bucket l by a thirdform of accessory.
Referring particularly to Figures 1 and 2, the
invention is illustrated in the form of a spin ning bucket 2 having a hub 3 adapted to cooperate with and to be driven by the spindle of a motor (not shown) a groove 4 in the upper portion of the interior of the bucket adapted to receive. a cover, a second groove 5 adapted to receive cover-retaining ring, and a false bottom '8 adapted to support the cake, the bottom being readily removable. This bottom, plate'may be like any of the types of plates heretofore sugthe upper surface thereof by which it is adapted to be seized by the tools inserted into the bucket in accordance with prior methods. However, such auxiliary elements upon the plate are'enwell'be provided to slope into each of IQ 'gested which containelements formed in or upon.
tirely unnecessary and are preferably avoided. 'this invention, a simple round plate or disk having plane surfaces is en- For the purposes of tirely satisfactory and has the advantages of being free of projecting elements which offer irregular surfaces orrecesses'which tend to catch lint, salt crystals, or dirt and tend to interfere with uniform winding of. the fllamentary material being collected in the bucket. The walls and actual bottom of the spinning'bucket-may be provided with the conventional form of perforations to drain the liquids therthrough where the bucket is to be employed in collecting freshly spun filamentary material which is still wet. In
addition, the actual-bottom l of the bucket is provided with aplurality of openings 8 (four being shown though as few as two or any greater number than two may be used).
The form of device shown in Figures for removingthejcake C from the bucket comprises a cup-like 'shell 9 having a central opening ID at the bottom thereof adapted to. receive the hub 3 of the bucket-and provided with an annular group of upstanding pins II which are preferably though not necessarily slightly shorter in height than the inside wall of the cup 9 so that the bottom l of the bucket when partially inserted into the cup 8 will act to center the bucket therein. Then,- merely by the bucket within the upper .edge of the cup, the operator will cause the holes 8 in the bottom I ofthe bucket to register with the pins 1 l" in the cup 9 and thereupon the bucket 2, falling of its own weight or with the aid of a slight push, it necessary, will cause the plate 8 supporting the cake within the .bucket'zfto be naised by the pins ll until the position shown in Figure 2,. is-
reached. The operator can then remove the cake from the raised bottom plate 8. To facilitate the registering-of the' openings 8 in the 1 bottom of the bucket with the pins H, arcuate grooves I! having sloped bottoms l3 may be formed in the bottom I of the bucket adjoining the openings 8 as shown inFigure While the grooves I! are shown in Figure 3 as approaching the openings 8 from one direction, they may as the openings fronrboth directions.
It is apparent that an annular ring whose band width is sumcient to support the cake and to cover the openings 8 in' the bottom of the bucket 2 may be'substituted for the simple disk or plate 8 shown in- Figures 1. and 2. In such 1 event, the button having. a height substantially land 2 equal to the thickness of the ring should be provided in the center of the bottom of the bucket.
In Figure e, a modified form of accessory is shown in the form of a block l4 whose upper surface is provided with the upstanding pins 15 adapted to raise the bottom plate 6 with the cake in the spinning bucket 2. vided with a bore l6 adapted to receive a sort of piston I1 in the form of an inverted cup the internal bore of which receives one end of a. spring [8 which tends to force the piston upwardly. The'spring is guided by a stationary post I9 projecting upwardly within the bore H; of the block. The block is provided with two vertical slots 20 extending from the bore I6 to 'the exterior of the block I4. These slots 20 are adapted to receive two pins 2|v secured upon the piston I1 and serve to limit the upward motion 01 the piston to the position show in Figure 4. The top of the piston I1 is provided with a centering' pin 22 adapted to cooperate with the spinrile-receiving bore of the hub 3 of the spinning box. The spring Hl may be sufficiently stiff to support the weight of the loaded spinning box in the position shown in Figure 4 in which event .ejection of a cak is accomplished by manually depressing th spinning bucket upon the piston I! after registering the pins with the open- This block II is protion of the cake with respect to the bottom of the box may be obtained. For example, the arrangement may be so designed that the upper ,surface of the bottom plate supporting the cake is'adapted to be raised completely out above the upper rim of the bucket. In this case, it is preferred that the thickness of th plate be such that its bottom surface will not be raised to a level above the-cover receiving ledge don the inside of the bucket rim when the plate is lifted to its uppermost position by the ejector device. Preferably, the pinsare of a length comparable to the sum of the depth of the bucket and the thickness of the portion of its bottom through which the openings extend.
The cake-ejecting accessory (or a plurality thereof) may be fastened directly to the framework of the spinning or twisting machine or to a suitable separate support nearby where it will ings 8.- Preferably, the pins [5 areof such height that the lower surface of the bottom I of the spinning bucket will strike the top of the pins l5 after the hub 3 of the bucket-has been the piston in the uppermost position shown but insufiicient to support in addition the'weight of the spinning bucket carrying the cake in which event,.'after centering, the spinning bucket upon the center pin. 22 and turning it to register the openings 8 with the ejector pins IS, the bucket will fall of its own Weight, thus ejecting the cake.
' Figures 5 and 6 show a modified form of device for assisting registering of the ejector pins IS with the openings 8 in the bottom of the bucket. In this form, a pair of aligned slots 23 are. provided inthe base of the hub 3 while piston I! of Figure 4 is provided with a. complementary pair of upright projections 24 on opposite sides of the centering pin 22, the projections 24 being so arranged with respect to the ejector pins l5 that when the slots '23 in the hub 3 fall over the projections 24, the openings 8 in the bottom of the spinning bucket are in register with the 'pins 1 5 of the ejector device.
In Figure 7, a modified form. of the invention is disclosed in which the driving-spindle receiving bore of the spinning -box extends clear through -the,hub'3" and the' ejector device consists simply of an' upright pin 25 supported 'on a suitable base 25. .This pin 25, as well as the f --to the thickness of the cake-supporting ejector platewithin the bucketthat any desired eleva- On the other'hand, the
be convenient to the operator when dofiing. Alternatively. each doffers truck used for receiving the cakes defied may be provided with one of the cake-ejecting devices of this invention. The vertical disposition of the device, that is with the ejector pins arranged vertically, is ordinarily preferredthough under some circumstances, an inclined disposition may be more satisfactory.
