This invention relates to a letterholder construction for
signs and more particularly to a letterholder adaptable for
mounting upon fluorescent lighting tubes.

The present sign holder generally indicated at 15, is
adapted to be slidably mounted upon the pair of tubes 12,
a fluorescent tube.
The aperture 33 opens in the rear
wardly extending gate 34. The housing includes the re
spective top and bottom walls 35 which towards their
forward ends and in conjunction with the end walls 32
define the rectangular opening 36 in the front of the
Rearwardly thereof and of slightly increased dimension
is the rectangular opening 37 within which is positioned a
corresponding letterplate 43 with suitable indicia or letter
ing or numbers, or the like, 44, as above described.
The letterplate 43 at its rear is retained within the
rectangular opening 37 by the continuous ñange 38 which
extends inwardly from the top and bottom walls 35 and
side walls 32. Front portions of the letterplate 43 are
retained at their top and bottom by the inwardly tapered
pair of flanges 40 which additionally form a part of the
top and bottom walls 35.
It is contemplated as a part of the present invention
that the said letterplate may be manually projected with
a slight flexing of the top and bottom edges of the letter
plate into the Yslot 37 from the front of the casing. This
is provided for by the outer tapered top and bottom v
ñanges 40 being of smaller extent than the correspond
ing rear continuous flange 38.

mounting on the letterhousing, normally some means
should `be employed for retaining the said housing in the
upright position shown in FIG. 5.

and an opposite end secured to the wall, the end supports
each being arranged substantially horizontally and being
elongated in its horizontal direction and of a uniform
vertical height which is less than the diameter of the
tube, the end supports thus being radially arranged rela
tive to the tube axis and normally arranged relative to
the wall and holding the tube parallel to but spaced a
short distance from the wall; said letterplate mounting
device comprising a tbox-like housing having a vertically
arranged front wall, centrally apertured to form a pic
ture frame, top and bottom horizontal walls, identical
vertical end walls, and an open back, all of the walls
being rigid and immovably connected together; said end
walls each having a circular opening of a size to slidably
receive the ñuorescent tube, the openings being horizon«
tally aligned; each end wall having a notch horizontally
extending from its rear edge into its opening and axially
aligned with the center of its opening, the width of the
notches in the vertical direction being slightly greater than
the vertical height of the end supports, the circular edges
defining the openings being otherwise uninterrupted and
engaging the periphery of the tube in a circular line con
tact, whereby the housing is mounted upon the fluorescent
tube by sliding it endwise upon the supported fluorescent
tube with the end wall openings slidably receiving the
tube and the notches slidably passing the support for thus
holding the housing upon the tube; and means for mount~
