f. Camera bed. The camera bed includes two tubular guide rails (figure
1) with an end block at each end. Wirerope pulleys are secured to brackets
within the end blocks. Two connecting bars between the tubular guide rails
provide additional rigidity for the camera bed.
g. Easel. The easel (figures 1 and 3) is hingemounted on the front
end and includes a blasted glass secured within the easel frame. Five
interlocking photographic masks [(1) below] are supplied to holdcopy to the
glass frame. Both the glass frame and the masks use clips to secure copy,
or the next smaller mask, to the easel. A calibrated mounting plate [(2)
below], mounted on a sponge rubber padded mounting board, and two glass
plates are also part of the easel.
(1) Masks. Five standard size interlocking masks (figure 3), ranging
in masks size from 3 1/4" x 4" through 11" x 14", are used to exclude
extraneous light from the camera lens. The large mask can be used by itself
to frame an object on the easel. However, when a smaller mask is used, it
must be mounted within the next largest mask. Thus, when the smallest mask
(3 1/4" x 4") is used, the largest mask must be first mounted on the easel.
provide copy support on the easel. The mounting plate has a white imprinted
scale, calibrated in inches, and a border imprinted for 8 1/2" x 11" and 8
1/2" x 14" sheets.
