DIRECTION SIGNAL.

Application filed November 1, 1921. Serial No. 512,001.

thus eliminating the possibility of the operators losing control of his car while attempting to glve a signal wlth his hand.

Other ob ects and advantages of my in vention reside in the novel construction and arrangement of parts as will be more fully described and claimed, reference being had to the accompanying drawings, in which,

Figure. 1 is a front view of the device shown applied to an automobile, the signal arm being visible,

Figure 2 is a similar vew of the device showing the signal arm hidden .from view, Figure 3 is a top view of the clamping means and operating lever, p

Figure 4c is a side view of the same, Figure 5 is a detail of the collar, Figure 6 is a detail of the signal arm, Figure 7 is a sectional view of the dash showing the device applied thereto,

Figure 8 is a detail of theadjusting I means, and

Figure 9 is a section on line 99 of Figure 1.

In the drawings, 1 represents the steering post of the usual type. A collar 2 is securely held to the post a sufficient distance below the steering'wheel 3 by any suitable means.

A sectional attaching band made up of sections 4: and 5 is provided to loosely fit the annular runway 6 in the collar 2. The sections 1 and 5 have apertured ears? and 8 on one end as shown, which are secured within the tubular casing 9 by a bolt 10. Section '5 of the band has its other end elongated to form an operating handle 11 having a knob 12. Another bolt and nut passes through apertures in the handle 11 and the ear 13 formed on section 4.

The tublar casing 9 is provided at the other end with a turned-down annular flange 14. which engages the enlarged head 15 on oneend of the plunger 16 operating within the casing. Thus the movement of the plunger is limited within the casing. The opposite end of the plunger 16 is provided with a ballshaped head .17 which is enclosed inv a cup socket 18 formed in the signal arm 19. The plunger operates within.

the slot S, as shown.

A casing 20 is provided so that the signal arm 19 may freely slide therein back and forth at the wish of the operator. I

Although the arm is shown as being operated from behind the dash-boardQl it is to be understood that the same may bereadily operated on the outer surface of the dash.

The ears? and 8 are so formed on the sections 4 and 5 respectively, that'they per- I mit. the casing 9 to swing within limits as shown. It will be seen that the ball and socket joint formed by the head-Hand socket 18 and thehinge joint at 10 provide a structurethat will permit a wider range.

of adjustment to various'makes of automobiles, and will also facilitate the operation 7 of the device.

An electric lamp L is rigidly connected to the casing 20 and projects within the hollow arm 19 thereby causing light rays to be emitted through the window W in the arm 19 when the lamp is lighted.

The slot S permits the arm to be moved backwardly and forwardly while the lamp L rojects therein.

n operation, when the operator of the automobile desires to make a turn to the left he grasps the handle 11 and by swinging the same around rotates the securing band about the collar 2. As the casing moves from inoperative position as in Figure 2 to operative positon as in Figure 1 the plunger moves backwardly and then forwardly to take theshorter radius during the swing. Since the head 17 is securely.

my invention, it is to be understood that various changes" and modifications may be made herein without departing fromthe spirit of the invention or the spirit and scgppe of the appended claims. claim l. A signal actuator comprising a lever rockable on a steering'post of an automo bile and having an adjustable arm whereby to conform the length'of the arinto the varying arc of rocking movement of the lever:

2. Ina signal actuator, a lever rockable on a steering post of an automobile, one of for the rocking. movement of the. lever, and an operating handle formed on the other.

arm.

4. A signal actuator adapted to be se= cured to the steering post of an automobile, comprising a collar rigidly secured to said steering post, a sectional'securing' band rotatably mounted on the collar, and having ears formed on each section, one section having an elongated portion forming an operating handle, a casing pivot/ally secured to the ears at one end of the securing band and a plunger limited to reciprocate within the casing. as the handle is operated,

said plunger being adapted for connection to .a signal device for operating the same.

5. A signal actuator comprising a casing,

a plunger adapted for connection with a signal device, said plunger being movable within the casing, a sectional securing. band pivotally connectedfwith the casing and having an elongation on one section forming'a hand grip, and a supporting collar having an annular groove for seating the'band and adapted to permit the band to oscillate about the collar.

6. A signal actuator comprising a'casing having an annular turned down flange at one end, a plunger having. a head adapted to engage a signal. device, said plungerbeing movable within the casing. and restricted in movement by the flange, a securing band having ears pro ect1ng-w1tl 11n the casing and pivotally connected with thesame,

a grip formed on the band, and a guide for the band for securing the same in operative position on a vehicle. said band being adapted to freely move over the guide when the handle is actuated.

7. A signal actuator comprising a hearing adapted for applicationto a steering post and a lever mounted between its ends on said bearing, being connected at its forward end with a signal and forming at its other end a handle whereby it may be operated. v
