:For indicating :the direction of vehicles zit has been proposed to use arrow shaped :images which are formed by an aperture inia- \wall or the likeand are provided with points in yboth directions. In such arrangements thearrow point which it is desired to show the direction to lbe taken is made .prominent either by means of-a fillingpiece ipushed behind the other-arrow point-or by :transparent illumination of the specific ;a-rrow point. According ltO :another mode arrows "are ;-assembled from mechanical elements. The first arira'ngement does :not insure the rapid and accurate:understanding of the given indication, especially by day-lighhwhen the-arrow point, which it is desired to make apparent differs onlyaslightlyifrom thezremainingone,

while the second construction :readily gives rise, after a certain wear has occurred, to

The presentiinvention :relates to direction indicating .devices, in which the..-arrow-like images appear 'in connection with an aperture when a .filling piece llS displaced -or rotated and consists in an' unfailing-although wsimple arrangement in which the arrow images are clearly and :rapidly recognizable. According to the invention the aperture has the shape=of a square, lozenge, hexagon or :the like having one of its :corners directed :to the left-and theiother zcornerito the right; .the ipointof :the arrow, which normally is invisible is formed :only after the ifilling piece has been displaced 'or turned, when thescontour OfZt-ll'lSfillllIg piece together with that of the aperture form the image of the arrow point.

In the accompanying drawings are represented in a schematic manner some of the many possible modifications of the invention in its substantial features, while the device which operates the apparatus is not shown. In these examples an element of the image is cut out in the casing of the apparatus or in another stationary part of the same, while the other element of this image is formed by a plate or the like movably mounted in this casing.

In the drawings the same reference characters indicate corresponding parts throughout and; Y

Figures 1 to 3 show front views of asquare casino; construction, the image element being shown in various positions,

gs. 4 to 6 are similar views showing a ilnodified image -.element construction, .and

Figs. 7 to .9 show front viewsiofv an ihexagonal casing -.construction, .'.the 1-image .ele- .ment being shown in .various positions.

Referring tirstto Figures 51 to 3 a square -.or'lozenge Z) is cutout in the front iwalliof the square or rhombic casing I an of the apparatus and formsnn-element of the image. Closely behind the front wall is mount-echa square MOI. lozenge c, which is displaceable sideways in bothidirections .andJforms the second image ,element. Under the influence .of an\eXternal-eifort, for example operable -.by the driver7s hand, the movable iElQHlQIlli' c .of the image isxdisplaced for .example .to the right .in such a manner "that a part-of its contour,.that:isythe left halfof thiscontour, forms with :a part of the stationary image element 6 an arrow ,1 Fig. 1. NVhen .the element 0 .is displaced to the left -.the lefthand effective lines of .the elements to .and'c forman arrow 2, Fig.3.- Thearrows :appear .for example whiteion a, darkwbasis -'or-, if an illumination from behind .is em- ,ployed, ethey appear .luminous .on via' dark field. When the image element-cis:adjusted ,in its inte-rmediate position nofinrageatall .is visible which .indicates :a.direction which is straight forward. i

In themodification. shown .in Figures =4 to .6 the movable image element isjforme d by .twosegmentsd and "c, which are pivot-ably imounted on axis mzand at 4311C]. cooperate in their common pivoting .movement. \Vhen .thesefsegments are rotated .to the right .an arrow 1 Fig. ,4, directed to theleftiappears and when they are rotated to the left an arrow 2, Fig. 6, directed to the rightappears, while in the intermediate position 0 the segments the image shown indicates a direction which is straight forward.

According to Figures 7 to 9 the stationary element of the image in the front wall of the casing a is formed'by a hexagon h and closely behind the same the movable parts f and g are arranged, which are provided with a horizontal central slot 3 and form together the movable hexagonal image element. According to the position of these parts f and 9 an arrow directed to the left 1 or the right 2 or a horizontal line 3 indicating a straight forward direction are formed similarly as in Figures 1 to 3.

These examples show that by a combination of different image elements as to their shape and number different constructive modifications of the principle of the invention may be carried out. When the inven tion is applied to a motor car an apparatus may be mounted on the front of the vehicle and another on its rear end without any changes in the construction of the car and both devices may be operated simultaneously by a single lever. i

In the above description the expressions left and right correspond to the figures in the drawing; it is evident that the direction of motion is different for apparatus mounted on the front or rear end of the vehicle. It should be understood that the square, lozenge or hexagonal shapes given as examples in the specification may be replaced by other equivalent shapes without deviation from the spirit of the invention.

Having now described my invention and in what manner the same is to be performed I declare that what I claim is:

1. A direction indicator for vehicles comprising a casing having a cut-out portion in the front wall thereof, said cut-out portion representing by the contour lines portions representing by the contour lines portions of arrows for right and left direction indications; and a movable image elen'ient in said casing adapted to co-operate with said outout portion, said element in a central position relative to the cut-out portion being unindicative of a right or left turn and when moved to the right or left in the casing the cutout portion and the image element forming a right or left arrow point by means of the contour lines of the cut-out portion of the casing and the image element to indicate a right or left turn.

2. A direction indicator for vehicles comprising a casing having a cut-out portion in the front wall thereof, said cut-out portion representing by the contour lines portions of arrows for right and left direction indica tions; and a plurality of image segments pivotally mounted in said casing cooperating 3. A direction indicator for vehicles coniprising a casing having a cut-out portion in the front wall thereof, said cut-out portion representing by the contour lines portions of arrows for right and left direction indica tions; anda pair of image segn'ients pivotally mounted in said casing cooperating with said cut-out portion, said segments in a central position relative to the cut-out portion being unindicative of a right or left turn and when rotated to the right or left in the casing the cut-out portion and the segments forming a right or left arrow point by means of the contour lines of the cut-out portion of the casing'and the segments to indicate a right or left turn.

1. A direction indicator for vehicles comprising a casing having a square cut-out portion in the front wall thereof, said cutout portion representing by the contour lines portions of arrows for right and left direction indications; and a pair of image segments pivotally mounted in said casing in opposite corners relative to the square cutout portion and cooperating with said cut-- out portion, said segments in a-central position relative to the cut-out portion being unindicative of a right or left turn and when rotated to the right or left: in the casing the cut-out portion and the segments forming a right or left arrow point by means of the contour lines of the cut-out portion of the casing and the segments to indicate a right or left turn.

In testimony whereof I afliX my signature.

AUGUSTIN MARSfK.
