TRAFFIC SIGNAL. i

" Application filed August 29, 1922. [Serial No. 585,010;

To all whom it may concern: v I I Be it known that I, THOMAS E. MoGLINoY, a citizen of the United States, residing at Swedesboro, in the county of Gloucester and Stateof New Jersey, have invented certain new and useful Improvements in a Traffic Signal; and I do hereby declare the following to be a full, clear, and exact description of the invention, such-as will enable others skilled in the art to which it appertains to make and use the same. p

This invention relates to a trafiicsignal. It is aimed to provide a construction whereby novel means in simulation of the movement of the hand may be provided to indicate to adjacent traific an intention to turn.

It is particularly desired to provide a novel construction which is compact, inexpensive and durable, which normally occupies a folded position against the car, does not detract from its appearance, and is adapted for use on closed as well as open cars and also when storm curtains are in place.

Specific objects and advantages will be pointed out and will become apparent in the following description of one operative embodiment taken in connection with accompanying drawings illustrating the same.

In said drawings Figure 1 is a view illustrating the invention in perspective and as applied to a windshield frame;

Figure 2 is a view ofthe invention principally in substantially longitudinally central section;

Figure 3 is a detail view electric switch employed;

Figure 4 is a detail viewof the connection betlween the operating arm; the signal arm, an

Figures 5 and 6 are detail perspective views of the clasp and clamp used in connection with the invention, and

Figure 7 is a sectional view of the switch, taken on the. plane indicated by the line 7-7 of Fi re 3.

Like reference characters designate like or similar parts in the diiferent views.

My improvements are adapted to be attached to the frameof the wind shield of an automobile. tionally shown at A having a frame B and particularly a post C to which the improveillustrating the ments may be connected. In the example A wind shield is conven illustrated, the signal is adapted ,to indicate a leftturn. "It-may be"used=however to in; dicate a right turn or oneof the' signals maybe-fused ateach side or end of the wind shield. I

The signal includes an armf10 which carries a semaphorel'h'which' may beshaped similar to thehuman 'ha'nd orotherwise'as preferred. A clamp is' employed at 1 2 which has arms or straps 13 in sections pivoted together at 14 and adapted to be fastened at the outermost sections to the arm 10 and clamped at the innermost sections as by separated arms at 17 intermediate which the arm 10 freely moves and by which arms 17 vthe'arm 10 is ada ted to be clasped and are preferably of ,re-

held. Said arms 1 silient metal and at their inner ends are rigidly clamped by a bolt or the like at 18 to the said post C.

tachably connected in any suitable manner to said post C. Rod 19 extends through an elongated slot 21 in the arm 10 and within the arm 10 a heador the like 22 is provided on rod19, thus providing a loose, pivotal or slip connection between arm 10 and rod 19.

As a result, it will be seen that the arm 19 may be raisedfrom the full line position of Figure 1, which is the signaling position and indicates a left hand turn, to the dotted line position in the same figure, which is its normal position. In the latter position, the arm 10 is upheld by the clasp engagement of member 17 therewith. Thus to apply the signal 10 the 'rod 19 is moved outwardly away from the operator and to restore it to normal position the rod 19 is pulled toward the operator.

The semaphore 11 may carry a suitable lamp at 23, which is preferablyan electric lamp and has wires or conductors 24 leading thereto and connected in circuit in any suitable manner with the'storage orother battery on the vehicle- Said arm 10 is hollow to accommodate wires 24 and the operating arm or rod 19 is also hollow and wires Any suitable means may be utilized in raisingand lowering the arm 10, For in- 24 are extended into the same and to an electric switch 25, of any suitable type, at the free end of the arm 19 and which switch is enlarged and adapted to engage the eyelet 20 and thus limit movement of the arm 10 to a horizontal or projected position.

The slip connection of the arm 19 at 21 is such as to enable the arm 19 to hang substantially vertically when the arm 10 is raised and in normal position. This is shown in dotted lines in Figure 1.

As merely one practical embodiment has been illustrated. and described, it is to be understood that changes in the details may be resorted to provided they fall within the spirit and scope of the invention.

I claim as my invention In signaling mechanism of the class described, a signal arm, means to pivotally mount said arm, illuminating means for said arm including a lamp thereon, an operating rod for said arm having slip connection therewith, a guide member through which said operating rod passes, said arm and op erating rod being hollow and having conductors to said lamp disposed therein, and a switch associated with said conductors at the operating end of said rod and engageable with the guide member to limit movementthereof and of the'arm.

In testimony whereof I affix my signature in presence of two witnesses.
