Application January .6, 1943, serial No. 471,457
3 Claims. (o1. Lio--smA
(Granted under the act of March 3, 1883, as
amended April 30, 1928; 37|) 0. G. ’757)
This invention relates to a data exhibitor and
has for an object to provide an improved data
exhibitor, wherein it is desired to have a great
deal of data readily accessible for selection of a
particular part of such data and for placing the
selected data in a readily visible position and
maintaining it in such readily visible position
without liability of being accidentally changed.
A further object of this invention is to provide
2
suitable apertures in one of the sides I'I or I8 of
the box body I I. The four spools on the two ends
of rods 20 and 22 are substantially identical and
each spool is formed in the shape of a hollow cyl
inder, as at:23, and terminates in an enlarged
bearing> 24 journalled in the aperture in the box
side I1. Beneath the bearing 24 the spool 23 be
comes an enlarged handle knob 25. These spools
23 are held on the rods 20 and 22 by having
a data exhibitor wherein a, great deal of data is
counterbored openings through the knob ends
placed' on scrolls", which scrolls are adapted to be
within which are placed a spring 26 vand a washer

of this invention, what is claimed is:

glass 42 thereabove. By selecting any one of the
knobs 25 the scrolls may be rolled in the appro
priate direction to make the desired data on the
scroll visible through the appropriate window
opening on the chart 3S. After the desired data
on the scroll has been brought into proper posi
tion, the spools 30 are rotated by means of their
knobs 25 until the spring 35 presses against the
through said Window chart, means for holding
said scroll against movement when the selected
scroll data is in appropriate position, said holding
