SIGNALING DEVICE.

Application filed August 12, 1919.

To all whom it may concern.

Be it known that I, RAYMOND G. SMITH, a citizen of the United States, and resident of Moss Beach, county of San Mateo, and State ofCalifornia, have invented a new and useful Signaling Device, of which the following is a specification.

My invention relates to direction and stop signals for automobiles.

An object of the invention is to provide a signal for'indicating to an observer either ahead or behind the automobile, the intention of the driver as to turning or stopping.

Another object of the invention is to provide a signal which is automatically cleared as soon as the turn is begun.

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of my invention which is illustrated in the drawings accompanying and forming part of the specification. It is to be understood that I do not limit myself to the showing made by the said drawings and description,

asI may adopt variations of the preferred form within the scope of my invention as set forth in the claims.

Referring to the drawings:

Figure 1 is a side elevation of the signaling device as applied to an automobile, of

which only such parts are shown as are needed to make the application of the device clear. Figure 2 is a side elevation of a portion of the apparatus shown in Figure 1, but on a larger scale. 7 Figure 3 is a plan view of the mechanism shown in Figure 2. Figure 4 is a front elevation of the signal frame, showing the movable signals exposed to indicate stop or slow down. Figure 5 is a rear elevation of the signal frame, showing a rear' signal exposed to indicate a turn to the left. Figure 6 is an 'end eleva- 'tion of the structure shown in Figure 5.

Figure 7 is a plan view partly in diagrammatic form showing the electric control switch of the signal lamps. Figure 8 is a diagram of the electric circuits in my signaling device.

Referring first to Figures 4:, 5 and 6, which show the construction ofthe signaling means. Suitably secured on the rear end of the car is a plate 2'upon which lain 3S 3 Specification of Letters Patent.

and 4t and movable signals 6 and 7 are arranged. Preferably also a tail lamp 8 and license nu r nber plate 9 are disposed on the plate 2. each signal 6 and 7 is preferably formed as an arrow and preferably is colcred. For instance, signal 6 may be yellow wlth a black center, and signal 7 may be green with a white center as indicated in Figure 4. Similarly the lamps 3 and 4 are colored yellow and green respectively, since signal 6 and lamp 3 act together, both conveying to the observer the same information.

7 signal 7 and lamp 4 are coordinated. Each movable signal 6 and 7 is mounted on parallel arms 11 and 12 which are pivotally mounted on the studs 13 arranged on the plate 2. A bar 14: connects all the studs and retains the arms 11 and 12 thereon. A coil spring 16 is interposed between each arm 12 and its stud and these springs are placed in tension when the signal 1s exposed. One end of each of the springs 16 is preferably engaged in one of the series of apertures 17 formed in the enlarged circular end 18 of each arm 12, and ad ustment ofthe tension is convenientlv secured by shifting the spring to enga e 1n the deslred aperture. The signals 6 arid 7 and their supporting arms are arran ed 111 different planes so that either signal or both together may be exposed or concealed without interference. A stop 19 -li1nits the exposing movement of the signals.

eans are provided for operating each signal 6 and 7 separately or together. lVhen separately exposed, they indicate a turn in the direction of the arrow. Together they indicate slow down or stop, or an intention to back up. Attached to the head 18 of the arm 12 of the signal 6 is a cable 21 which passes through the conduit 22 conveniently disposed in the frame of the automobile. Pivotally mounted on the shaft 28 secured in the bracket 2 which is suitably fixed on a convenient portion of the car, is a lever 26. The cable 21 is connected to the lever by the U-form link 27, so that when the lever is turnedto expose or raise the signal 6, the point of pivotal connectionwith the linkpasses the dead center, the parts being then retained in position, the signal 6 exposed, by the tension of the spring 16. 1V hen the lever is moved in the opposite direction off the dead center, the spring 16 insures the movement of the signal to concealed position behind the plate 2.

At the front end of the car is referably arranged a signal apparatus simi ar to that at the rear end and the corresponding movable signals 6 and 7 are similarly connected to lever 26 by cable 21' and link'27, the cable passing through the conduit 22. Thus when-the lever isturned to expose the nals, it rotates past its dead center in respect of both links 27 and 27. The movable signal at. the rear of the car which when exposedalone indicates a turn to the right, andthe corresponding-signal at the front of. the car, are similarly connected to a lever 28,F igure 3, mounted on the shaft23 and similar to and spaced a short distance from thelever 26. There are thus two setsof signals, one'at each end of: the car, and cor- "responding signals of the two sets are connected for unitary operationso that: the intention of the driver as to turning or stopping maybe shown at both front and rear ends of the car.

"Means are provided for manually control ling or actuating the levers 26 and 28, and this means also is in duplicate so that each lever may be actuated separately. A lever '31 provided with a handle 32 convenient to "the hand of the driver is, pivotally fixed on the steering post33 of the automobile, and

is connected by link' 34 with lever 26 in such manner that when the lever 31 is pulled upwardly the lever 26 is rotated toexpose the signals 6-and 6. A similar lever and handle isprovided for the movement of lever 28 andis connected to that lever by the link 36,

37. The lever arms are connected by a pin 38 which extends outwardly below the edges ofithe levers 26 and 28 andalso acts as a pivot pin connecting the two levers 37 with a link 39 attached at its other end tothe brakevpedal lever 41. Movement of the brake pedal to-apply the brakes thus swings the levers 37, engaging the pin 38 with both levers 26 and 28 and turning them to eifect the exposure of the front and rear signals of both pairs, thus indicating a stopping or slowing down of the car. 'Release of the brake pedal permits the signals to return to concealed position.

'Mtaains are provided for automatically -"clearing the signal after the evolution indicated has been performed, although of visible.

course the signal may also be cleared by movement of the handles 32 back to first position. This automatic clearing preferably depends on the movement of the steering wheel, so that the mere act of turning the steering wheel is accomp anied automatically by a clearing of the signal. Fixed on the horizontal shaft 42 which is mediately connected to the steering wheel by the usual worm wheel, worm, and steering rod, and which is also mediately connected to the steering knuckles of the front wheels by the usual steering lever43 and link 44, is alever arm 46 connected by link 47 with a; pair of levers 48. The levers 48:are pivoted on pins 49, one on each side of the bracket 24 and each lever48 is provided with pins 5l-spaced on each side of the: pivotpini49. The position of the levers 48 is such: that the pins51 underlie the-upper ends of the levers 26and 28, so that when those levers are .turned .down to expose the signals, theupper: ends thereof engage the two pins 51 oneach lever.

Normally the levers 48 are in horizontaL po sition and when eitheror both levers 26 and 28 are turned down they pass the dead center before engaging the.pins 51. F-rom the above it will be seen that movementoii the steering wheel in either direction will tip the levers 48 and moveeither one or the other of the pins 51 upwardly, thus throwing the engaged lever 26 or 28 upwardlywand off dead center so that thelever returns to normal positionand'the signal: to concealed position.

Means are provided for operating the lamps 3 and 4 of each-signaling device in conjunction with the movable signals when it is desired to do so. These lamps not only convey information similar to that of the signals but also helpto illumine the .movable signals, so that at'such times bothiare The lamp 3 at the rear ofthe car and lamp 3' at the front are connectedin parallel by the conductor 52, the circuit being grounded at 53. A sprin switch 54 closed by pressure on the button'56 provides connection between the conductor 52 and the conductor 57 connected through switch 58 to the battery 59 which is also grounded at 53. Similar connections including'the switch 60 operatedby thebutton 161: are vI provided for the lamps .4 and4= in the rear and front signals respectively. Thetail lamp 8 is also connected in. parallel with the other lamps by conductors 62, this circuit being also grounded.

The two switches 54and 60 are-enclosed in a box 63 arranged'on. thestecring column so that the buttons: 56 and '61 which are beveled are engaged and pressed inwardly by thesignal control levers whenrthe. latter are raised to operate the movable signals. I-Thus, when lever 31 is pulled upwardly,not

only are the movable signals 6 and 6'- ex posed but the button 56 is pressed inwardly, closing the switch 54 and if the control switch 58 be closed, lighting the lamps 3 and 3. The several circuits are connected into a suitable fuse box 64 set on the back of the instrument board 66, and pilot lights 67 are preferably disposed in each circuit.

In order that lights and signals of the same color may point always in the same direction relative to the observer Whether he is behind or in front of the car, the front left signal and lamp and the rear right signal and lamp are of the same color, in the present instance green. Similarly the front right signals and the rear left signals are of the same color.
