With this particular assembly of, the device the unwritten side of the paper strip I is exposed for writing purposes and the supply spindle becomes the take-up spindle .and the take-up spindle becomes the supply spindle. After the strip has been used on both sides or on one side alone the spindle onwhich the strip is wound may be removed'from the frame and sent to any desireddestination by enclosing it in a suitable container. Should the ends of the spindles fit but loosely in their reberswith two spaced apart pairs of axially aligned spective split jaw type bearings the bearings may be tightened by tightening the adjusting screws. By reason of the fact that the frame 1 includes the feet I9 theportions of the strip which extend between the spindles and the lower and upper cross members of the frameare spaced above the supporting surface on which the frame rests in connection with use of the device. By having such portionsof the strip disposed above the support ing surface (see Figure 4) any writing in ink on the strip is not brought into contact with the supporting surface in connection with feed of the strip across the top face of the board.

The herein described writing device is essentially simple in construction and design and hence may be manufactured at an extremely low and reasonable cost. It has many capabilities of use and is characterized by the fact that the particular bearing arrangement for the supply and takeup spindles permits the spindles tobe quickly and readily shifted into and out of place. The device I is further characterized by the fact that it is durable and rugged while at the same time it is light in weight and may be readily carried or transported. v

The invention is not to be understood as restricted to the details set forth since these may be modified within thescope of the appended claims without departing from the spirit and invention What I extending around, and dependingfrom, the edges v of the board, and embodying a pair of side memthe ends of the side members, arranged so that the fiat sides thereof are inwardly disposed, their rounded surfaces are outwardly disposed and their upper edges are flush with the top surface of the board, and forming with said board and side members a chamber that is'closed except for the bottom, and a pair of transversely extending rotary spindles disposed for the most part in said chamber journalled in the two pairs of bearings, respectively, and adapted to support a strip of flexible writing material for feed around the rounded surfaces of the cross members of the frame and across the top face of the board.
