9 Claims. '(01. 57.416)

`This invention relates to improved cover-locking means for spinning buckets such as are used in collecting artificial lamentary material. It is particularly concerned with a novel form of cover-locking means adapted to automatically lock' by virture of centrifugal force upon rotation of the bucketl land to be readily released by the fingers of an operator when he removes the cover from the box or equally as readily by a cake-removing device adapted to be inserted into the box when a form of box is employed which permits the removal of the cake therefrom by means of such a device.

In the drawing, illustrative of the invention,

Figure l is an elevational view in cross-section of the combination of a spinning bucket with the cover-locking means and a device adapted to remove the cake therefrom,

I Figure 2 is a plan view of the cover with its locking means, and

Figure 3 is a view showing a locking element enlarged.

Figure 4 is a vertical crossfsection of a spinning bucket inverted upon a cover releasing form, and

Figure 5 is a plan view of the cover releasing form.

The spinning bucket 2 is provided with a groove 3 in its upper internal periphery which is adapted to cooperatewith the bucket-engaging members 4 provided within the cover 5. Y These members 4 are shown in detail in Figure 3 and each comprises an elongated finger-like body portion having a longitudinal slot 6 therein. Thev body portion terminates in the bucket-engaging tip 'l shaped to conform with the groove of the bucket. The other end of the elongated body portion is provided with the upstanding portion 8 which is provided witha sloped surface 9 down to the body portion. These finger-like members are mounted slidably within radially extending slots I0 of rectangular cross-section within the cover and the overall length of these members preferably corresponds to the difference between the inner and outer radii of the annular cover which may be provided at its inner periphery with an upstanding annular portion II. A pin Illa may be provided in the cover to cooperate with each o slot 6 to limit its slidable motion. The annular portion I I as well as the upper face of the cover is cut away suitably as at I2 to permit a certain amount of radial motion of the finger-like member (with its upright end portion 8. This is preferably done in a manner to minimize air resistances and, as shown in Figures 1 and 2, an

surface of the cover which extends down to the recesses I0 within which the finger-like mem- -bers are set. Upon rotation of the spinning bucket after the cover has been put in place,

.f these finger-like members l are thrown outwardly into engagement with the groove 3 provided within the internal periphery of the bucket, thereby locking the cover inplace during the collecting operation. After the cake has been co1- lected and it is desired to doff, it is merely necessary for the operator vto place his lingers upon 4the several sloped surfaces 9 of the finger-like members 4 and press them inwardly, at th same time grasping the upstanding annular ring II upon the cover for simultaneous unlocking and removal by hand of the cover.

The operation just described refers to the simpl'e manual removal of the cover 'which may be followed by the removal of the cake by any suitable means, siich as the inversion of the bucket and removal by gravity with manual assistance. However, it is also within the contemplation of this invention to provide the spinning box with a removable element I4 for supporting the cake within the bucket' and to remove the cake with this supporting element by means of a device I5 which is adapted to release the cover-locking means upon insertion into the bucket.

Any suitable form of cake-supporting element t I4 and cake-removing device I5 may be employed. Figure 1 shows one preferred embodiment formed of a cylindrical member I6 having a diameter adapting the member to slidably fit within the internal periphery of the cover 5 and provided at its lower end with an inwardly flared portion I1 adapted for firm seating engagement with the complementarily shaped internal periphery of the cake-supporting element I4 and with the spring element I8 having hook-like portions I9 adapted to permit insertion of the lower end of the device into the internal periphery of the removable element I4 and to thereupon spring outwardly intoy the undercut portions 20 of the removable element and clamp it into firm seating engagement with the flared portion Il of the f with a flared portion 2l across which a handle in annular; groove I3 may be provided in the top 55 the form of a tube or rod 22 extends. The device is also provided at the upper end of the cylindrical member with an annular concentric depending sleeve 23 which engages the sloped surfaces 9 upon the finger-like members as the cake-removing device seats itself upon the. cakesupporting element I4 within the box, in this fashion disengaging the cover from the spinning in Figures 4 kand 5 comprises two upright guides.

24 and 25 and af'vertica1 tubular member 26 concentric therewith.

tion Il of the cover and to force the members d inwardly by contact with their slopedsurfaces 8 when a cake-filled bucket is inverted and deposited on the form while being directed by the

guides

24 and 25. Upon lifting the bucket, the cake is left upon its cover and may be readily grasped without seriously damaging it to remove it to any desired point of operation.

- Whiley preferred embodiments of the invention have been shown, it is to be understood that changes and variations may be made without departing from the spirit or scope of the invention as dened by the appended claims.

I claim:

1. A spinning bucket cover having a plurality -of radially slidable cover-locking members arranged to be thrown centrifugally into engagement with a spinning bucket upon rotation there- 'Ih'e tubular member is' f adapted to encircle the upstanding annular porspinning bucket upon rotation therewith and having sloped portions normally retracted within said member but movable outwardly with respect thereto upon movement of said means into bucket engaging position.

6. An annular spinning bucket cover having a plurality of cover-locking members recessed therein'radially movable inwardly to retracted position and outwardly into bucket engaging position, said members having inner portions having outward-facing sloped surfaces and an annular groove in the upper surface of said cover surrounding the sloped portions of said members for accommodating a device for embracing and retracting the sloped portions and thereby said members.

7. A spinning bucket having an annular cover, upstanding means on said cover affording manual gripping thereof, cover-locking means on said cover arranged to be thrown centrifugally into engagement with said bucket, said cover-locking means being provided with manual releasing with, said members having bucket engaging portions attheir outer ends and upwardly and inwardly sloped portions: arranged at their inner` ends and adapted to be embraced and to be moved inwardly by a common encircling device whereby release of said cover-locking means from said bucket is effected.

2. A spinning bucket cover releasing device comprising a tubular member and means associated therewith for guiding aspinning bucket concentrically with respect thereto. A

3. A spinning bucket cover releasing device comprising an upright tubular member and means arranged outside said member presenting a guideway extending in a direction parallel to the axis of said member.

4. A spinning bucket cover releasing device comprising an upright tubular member and guide means arranged concentrically about said member for guiding a spinning bucket having a cover locked therein into concentric axial relationship with the tubular member to release the cover.

5. An annular spinning bucket cover having an annular hand grip member adjacent its internal periphery, means in said-cover arranged to be thrown centrifugally into engagement with a means arranged in proximity to said manual gripping means for vsubstantially simultaneous manipulation therewith.

8. A spinning bucket having va cover, an upwardly extending annular hand grip member adjacent its' internal periphery, at least one radially movable cover-locking element having an youter bucket-engaging portion andan inner portion provided with an inwardly and upwardly sloped surface facing outwardly, said element being arranged to be thrown centrifugally with its outer portion into bucket-engaging position and with its sloped surface to a position externally adjacent to said. hand grip member whereby substantially simultaneous manipulation of said element by its sloped surface portion to release the cover from the bucket and manual gripping of said cover by said hand grip member may be effected.
