8 Claims.

This invention relates to rotatable bins having removable dividers and has for its object t provide means biasing said dividers to a position in which each is held securely fastened to the bottom of a bin section.

Another object is to provide means for quickly and easily inserting or removing a divider whereby a bin section may be readily changed or adapted to the desired purpose.

1'0 Removable dividers have been suggested for bin sections but they have been diflicultly removable. One suggestion contemplated their being held in position by nuts yand bolts which took substantial time to apply and tighten or to re- '15 move. Another suggestion was for a pair of PIO- jection recess connections between the bin Section bottom and the lower flange on a removable divider, such connections being engaged on radially outward movement of said divider, and a snap type fastener was used for holding the divider in its engaged position. This last construction contemplated having to laterally bend or flex the top edge of the removable divider, which was not always easy, especially if a load precluded such lateral bending. Also if the load Was so arranged as to be in danger of flexing the divider unintentionally, the snap fastener may become disengaged and the divider Work loose. In order to avoid these difliculties the' present in- 30 vention has provided greater ease of operation.

VSpecifically this invention includes a rotatable bin section having a bottom portion secured to a sleeve which is mounted on a central supporting post about which the section and sleeve may ro- There are removable dividers radially arranged and provided with a flange contiguous the bin section bottom, there being fastening means between the divider ange and bin section bottom which is so constructed as to be engaged '40 and disengaged on radial movement of the divider with respect to the bin section bottom. In order to bias the divider radially in a direction to keep said fastening means engaged, there is provided a spring or other means cooperating with the divider and sleeve for pressing the divider into a position in which said fastening means are held in engagement. Y

able bins, there isprovided a central supporting y.post I0, .about which a sleeve or abutment I'I is 'mounted on ball bearings I2 for rotation, said ball bearings being supported by a pin I3 or other convenient means. Secured by welding to the- 5 rotatable sleeve II is the bin section bottom I4.

Each permanent divider I5 has an inner ange I6 welded to the sleeve II and a bottom iiange I'I spot welded to the bin section bottom I4.

A flange I8 is bent up around the periphery of 10 the binsection bottom. Between pairs of ypermanent dividers I5 are mounted the removable bin fronts I9 which are preferably secured to the permanent dividers and to the bin section bottom as described in my previous applicatiomm Serial Number 58,071 (Pat. No. 2,086,508) for Rotatablebin, led January 8, 1936'.

Between the permanent dividers may be mounted one or more removable dividers 2| each having a bottom iiangel 22 provided therein with0 recesses 23 adapted to receive the stamped up projections '24 on the-bin section bottom. Each movable divider is secured in positionv by inserting the recesses 23 over th'e projections 24 and vthen moving the divider radially outwardly .1 25 enough to maintain the projections engaged over the top of the bottom flange 22 as shown in Fig.

2. The front or outer edge ofeach removable divider may be cut away as at 25 to clear the up-turned iiange I8. 30

The top edge 26 of each permanent andremovable divider is reenforced by an attached bit yor by bending over some of the metal to form a stiffening ange. Such top edge is generally unsupported and out of contact with any super-1 35 posed bin section. 'I'he inner edge 26a of each removable divider is held by the guide means or divider locator 2l which is riveted or welded to the sleeve II and notched as indicated so that the upper inner edge portion of a removable divider is retained against lateral fiexure. Below theholding device 21 is a spring means or divider locator 28 for pressing the removable divider radiallyoutward to maintain the projection and recessY connecting

means

23 and 24 in engagea 45 vThis spring means includes a number of leaf springs 28 securely held` to an attaching piece 29 by astam'ped out strip 30 beneath which the several leaf springs are inserted, the strip 29 being welded or riveted to the sleeve II. Each leaf spring is curved upwardly and outwardly and its upper end portion notched at 3| as shown in Figs. 3 and 4 to receive one of the removable dividers. The radial movementv of a removable divider is not largeso the upper end. of the spring.;

28 engaging a removable divider is not required to be distorted to any substantial extent.

To engage or attach a removable divider the inner edge portion 26a. is inserted in the desired notch of the guide means 21 and in the desired notch of the appropriate spring finger 28. By slight inward pressure on the divider against the spring 28 the holes 23 are brought into engagement for the projections 24.

The spring 28 may be strong enough to push the movable -divider radially outward to the position shown in Fig. 2 or, if desired, such radially outward movement may be applied manually and the spring 28 only str-ong enough to maintain the divider in this position, but preferably the spring 28 is made strong enough to push the removable divider forward into its engaged position. In Fig. 1 the bin section bottom is shown as being provided with a number of projections 24, the number depending on the number of removable dividers which mightV be desired. Said projections 24 are relatively low and substantially rigid so they are not in danger of being out of shape or of offering any serious obstacle to the storage of whatever materials may be kept in the bin section above such projections 24 in case there is no removable divider engaging these projections.
