Abstract

A dual-spindle support for rolled paper is illustrated and is exemplified by two hinged-support flaps 10. The support flaps are pivotally mounted upon paper drawer 12 and connected to links 14. Links 14 extend toward each other and are pivotally attached to latch disk 16 at diagonally opposite positions. Latch disk 16 may be operated in a counterclockwise direction, as indicated, to pull links 14 toward each other and thus pivot flaps 10 inwardly to support a paper roll.

Dual Spindle Paper Drawer

A dual-spindle support for rolled paper is illustrated and is exemplified by two hinged-support flaps 10. The support flaps are pivotally mounted upon paper drawer 12 and connected to links 14. Links 14 extend toward each other and are pivotally attached to latch disk 16 at diagonally opposite positions. Latch disk 16 may be operated in a counterclockwise direction, as indicated, to pull links 14 toward each other and thus pivot flaps 10 inwardly to support a paper roll.

Flaps 10 carry spindle supports 18, so that the spindle supports will freely rotate and at the same time engage the end portions of the core of a paper supply roll. On spindle supports 18, a U-shaped member 20 is attached to the spindle support 18 to aid in the engagement of this spindle support into the end opening of a core having only a partial roll of paper thereon. The force of latching disk 16, transmitted through links 14 pull the spindle supports 18 together with the U-shaped member 20 acting to lift the core and center it on the spindle supports 18.

The length of links 14 is determined such that the latch disks 16 may be rotated until the pivot points connecting links 14 to disk 16 are in a horizontal plane, thereby allowing the latch to lock the links in their retracted position by overcenter detent. To release an empty paper core or to replace a partially used roll, latch 16 is rotated in a clockwise direction to disengage the spindle supports 18 from the ends...
