ERNST W. GMELIN, OF EL PASO, TEXAS.
DIRECTION-INDICATOR.Specification of Letters Patent. Patented Mar. 16, 1920.
Application -led August 20, 1918. Serial No. 250,692.To all whom it may concern:
Be it known that I, ERNST WILuiELMi
GMELIN, a subject of the Emperor of Ger-
many, residing at El Paso, in the county of
5 El Paso and State of Texas, have invented
certain new and useful improvements in Di-
rection-Indicators; and I do hereby declare
the following to be a full, clear, and exact
description of the invention, such as will
10 enable others skilled in the art to which it
appertains to make and Pse the same.
This invention relates to improvements in-
direction indicators, and has for one of its
objects the provision of means whereby an
15 operator of an automobile may readily in-
dicate to traffic in front and rear thereof in
which direction a turn is to be made or if
a stop is contemplated.
Another object of this invention is the pro-
20 vision of signaling members slidably mount-
ed on the automobile and adapted to be slid
laterally thereof, so that traffic in front and
rear can readily see and determine the course
of the respective automobiles.
25 A further object of this invention is the
provision of means for automatically illu-
minating the signaling members when moved
into signaling position.
A still further object of this invention is
30 the provision of a direction indicator of
the above stated character, which will be
simple, durable and efficient, and which may
be manufactured and sold at a compara-
tively low cost.
35 With these and other objects in view, as
will become more apparent as the descrip-
tion proceeds, the invention consists in cer-
tain novel features of construction, combi-
nation and arrangement of parts as will be
40 hereinafter more fully described and claimed.
For a complete understanding of my in-
vention, reference will be had to the fol-
lowing description and accompanying draw-
ings, in which:
45 Figure 1 is a fragmentary side elevation,
partly in section of an automobile illus-
trating my invention applied thereto,
Fig. 2 is a vertical sectional view of a
direction indicator constructed in accordance
50 with my invention,
Fig. 3 is a transverse sectional view, illus-
trating the means of supporting the signal-
ing member,
Fig. 4 is a fragmentary view, illustrating
55 means for automatically illuminating the
signaling members,Fig. 5 is a fragmentary plan view of the
brackets,
Fig. 6 is a side elevation, partly in section,
of one of the signaling members, 60
Fig. 7 is a sectional view of the same,
Fig.8 is an end elevation of the device.
Referring in detail to the drawings, the
numeral 1 indicates as an entirety an auto-
mobile including a body 2, having an in- 65
strument board 3 and a windshield 4. The
foregoing description relates to a well known
construction of autormnobila and to which my
invention is applied.
Brackets 5, having downwardly inclined 70
arms 6, are secured to the instrument board,
as illustrated at 7. The brackets 5 are pro-
vided with a tubular portion 8, provided
with upstanding flanges 9, having their in-
ner faces at their upper ends cut away, as 75
illustrated at 10, to permit a bar 11 to slide
freely between the same. A bracket 5 is se-
cured to each end of the instrument board
3, and supports the ends of a tubular mem-
ber 12, which is provided with longitudinal so
slots 13 in the top face thereof, and which
slots extend from each end toward a point
intermediate the ends. The slots 13 termi-
nate in spaced relation to each other at the
intermediate portion of the tubular mem- 85
ber 12 to form a solid portion or stop 14.
The tubular member 12 is secured within
the tubular portion 8 of the brackets 5 by
means of set screws 15.
Guide members 10 are slidably mounted 90
within the tubular or supporting member 12
and have formed thereon upstanding arms
17, which connect with the ends of the bar
11. The bar 11 has secured to each end
signaling members 18 in the form of hands, 95
but may be of any other desired shape. The
signaling members 18 may be painted, or
otherwise coated, in any desired color, pref-
erably white, so that they can be readily ob-
served by approaching and following traffic 100
of the respective automobiles. The signal-
ing members 18 are provided with cutout
portions 19 in which are positioned electric
lamps 20. The electric lamps 20 are sup-
ported within the cutout portions 19 by 105
means of reflectors 21 secured to the signal-
ing members by arms 22, so that the rays of
light from the electric lamp will be directed
downwardly over the signaling members,
thus making them visible at night time. A 110
suitable handle 23 is secured to the bar 11,
and is normally positioned adjacent the1,333,973.
