upper part of a sign assembly having a visual/audible warning assembly in accordance
with a second embodiment of Cameron's invention. Figure 7 depicts a hand-held
warning sign assembly in accordance with another embodiment of Cameron's invention.
Cameron teaches that the combination of a light and a horn in the assembly provides
strong visual and audible signals for drawing a person's attention to the written warning
which is displayed on the panel section of the sign.
The hazard warning sign assembly 10 shown in Figure 1A is made up of (1) a
display panel section 12, (2) a combined warning light and audible signal section 14,
(3) a power/control section 16, and (4) a telescoping pole section 18. The panel
assembly 12 includes a sign plate 20 having first and second display surfaces 22a, 22b
(22b being shown in Figure 1B) in which appropriate warnings may be painted or
otherwise displayed. For example, in the embodiment which is illustrated in Figures
1A-1B, which is adapted mainly for roadside traffic control use, the first side 22a
displays the word "STOP" while the opposite side 22b displays the word "SLOW." A
hollow support rod 26 extends vertically across sign plate 20, with the combination
warning light/audible warning assembly 14 being mounted on the upper end
of this and the power/control assembly being attached to its lower end. The hollow
support rod 26 provides a conduit for wire leads supplying power from the power/control
assembly 16 to the light/horn assembly 14.
