' DIRECTIONAL SIGNAL FOR AUTOMOBILES Filed May 2l, 1955 5MM@ ESM@ INVENTOR wlrNEss ATTORNEY Patented Aug. 11, 1936 HT E S TAT S 1 Claim.
This invention relates to directional signals for .use on automobiles and has for an object to provide a signal light in which the turn signal is given both to .the front and to the rear of the automobile.
A further object is to provide a novel form of signal light in which the characters indicating corresponding turns intended to be made, are disposed in separate compartments in the lightandv are selectively illuminated by incandescent bulbs controlled by a switch within convenient reach of the driver.
A further object is to provide a safety turn light which may be readily attached to the side of'an'automobile without alterations to or `mu tilation of the -front post of the body of the automobile.
A further object is to provide a directional signal llight which will be formed of a few,
simple, strong and durable parts, which will be inexpensive to manufacture and which will not easily vget out of order.
With the above and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood .that various lmodifications Vmay be resorted to `within the scope of the appended claim without departing from the spirit or sacrificing any 3 ofthe advantages of the invention.
Figure 1 is a rear elevation of a directional signal light constructed in accordance with the invention, in applied position on an automobile.
Figure 2 is a longitudinal sectional view taken on the line 2-2 of Figure l.
Figure 3 is a longitudinal sectional view taken on the line 3-3 of Figure 2.
Referring now to the drawing in which like characters of reference designate similar parts in the various views, ID designates the cylindrical wall, and II and I2 designate the front and rear walls of the signal light casing, these walls 45 all preferably being formed of opaque material such as metal or the like. The front and rear Walls are provided with rim anges i3 which .overlap the cylindrical Wall Il! and form means for removably securing the front and rear walls in place. The cylindrical wall is provided with elongated openings I4 in the form of arrows preferably and over these openings transparent closures I 5 such as Celluloid or the like are placed on the inner surface of the cylindrical wall. These openings permit light rays being projected upwardly or downwardly when corre- In the accompanying drawing forming part spending signal characters are illuminated as will presently be described, to enhance the visibility of the signal lamp to an approaching driver or a followingldriver.
The circular front and rear walls lI l and I2 "5 areiprovided with'characters It and Il disposed in superposed relationship and formed by cutting away the material of thewalls, the upper character preferably being an arrow having its shank directed downwardly `irriidway "of the ien'ds 10y to indicate a left turn. The lower character is similarly v'forrneol by cutting away the material of the walls and is U-shaped in outline to indicate that/aU -turnis intended Lto be made. Both characters are located in a respective quadrant 15 of the wall on the same side of the vertical diameter of the wall.
Transparent closures i8 of Celluloid Ior like material are engaged over the characters and are secured to the inner Vfaces ofgthe front and rear walls in any preferred manner. 'I'hese closuresprevent access'of dust and foreign matter tothe interior of v:the casing 'but'do lnot interfere with the eiicient projection of light ray through the turn indicating characters.
A transverse partition I9 is disposed in the casing, the ends of the partition being provided with flanges which ar-e secured to the cylindrical wall of the casing by rivets 20 or other suitable connectors. The partition divides the casing into an upper compartment and a lower compartment which .rare entirely separate from each other. The upper compartment houses the characters I6 which indicate left turns on the front and real walls of the casing, and the lower compartment houses the characters Il which indicate U turns on the front and rear walls of the casing. It may thus be seen that when either compartment is illuminated the corresponding turn indicating characters will be illuminated to indicate the intended turn to be made.
A longitudinal partition 2l is secured in each compartment midway between and parallel to the front and rear walls of the casing. The partition may be formed of sheet metal and may be secured in position by means of a ange 22 which is riveted as shown at 23 or otherwise secured to the partition i9. Each partition 2l is of greater extent than a quadrant of the circular walls of the casing so that when the arcuate edge of the partition is disposed to co- 50 incide with the arcuate inner face of the cylin-v drical wall I 0 of the casing, the end edge 2li of the partition is disposed beyond the axis of the cylindrical casing as best shown in Figure 3.
construction permits of suflicient space being left beyond the edge of the partition to permit of an incandescent bulb 25 being so located in the casing that its rays will illuminate the particular compartment in which it is situated. The partition will also be illuminated and form a bright background for the transparent signal character associated therewith.
The incandescent bulbs 25 are of conventional type and are mounted in sockets 26 of the conventional type having bayonet slots 21 which receive pins 28 projecting from the bases of the bulbs. A yoke 29 is provided with arcuate ends 3i] which are secured as shown at 3| to the cylindrical wall of the casing. The yoke is provided with openings which receive the sockets 26, and each socket is confined in the corresponding opening by a stop collar 3Q and a nut 3i' bearing against oppositesides of the yoke.
The conductor wires 32 from the battery 33 are secured to the sockets in the conventional manner, that is the bared end of each Wire is secured to the corresponding socket by a set screw 34 and a knurled nut housing 35 is screwed onto the end of the socket over the set screw as best shown in Figure 2.
For attaching the signal light to the left post 35 of the automobile a pipe 31 is inserted at one end through a suitable opening 38 formed in the post. Securing plates 39 are mounted on the inner and outer faces of the post, these plates being provided with bosses 40 which receive the pipe. Screw bolts 4l are passed through the plates and through suitable openings 42 formed in the post. A nut 43 is screwed onto the end of the pipe 38 inside the automobile and is turned up tight against the boss on the inner attaching plate to adjustably secure the pipe in position.
A yoke 44 is secured at the bight to the pipe 31 and preferably an insulating strip 45 is secured to the inner face of the bight and over this strip the end of the pipe is flared as shown at 46 to form a stop. A nut 41 is screwed onto the pipe and engages the outer face of the bight of the yoke to tightly secure the yoke to the pipe. The branches of the yoke are secured to the branches of the socket carrying yoke 29 by means of rivets 48. The yoke 44 it will be seen thus houses the knurled nuts 35 but permit backing 01T of the nuts to facilitate repairsl without dismantling any part of the light.
A switch 49 may be secured to the steering post 5G of the automobile by means! of a ring strap bracket 5| having the legs 52 secured in any preferred manner to an insulating plate 53 which carries two switch contacts 54 to which the conductor wires 32 are secured and also a switch contact 55 to which the conductor wire 55 from the battery 33 is connected in the usual manner. A T-shaped switch 51 is pivoted on the switch Contact 55 as shown at 53. When the switch is swung in one direction the lateral branch oil the T-shaped switch will make contact with one of the switch contacts 54 and when the switch is swung in the other direction the opposite lateral branch will make contact with the opposite switch contact as will be understood.
In operation when the driver throws the switch 51 in one direction the corresponding incandescent bulb in the casing will be energized and the associated signal character in both the front and rear walls of the casing will be illuminated. For example when the switch is swung to the right the left turn characters I6 will be illuminated and when the switch is swung to the left the U turn characters will be illuminatedjthus indicating to an approaching or following driverrthe. turn that is intended to be made.
From the above description it is thought that the construction and operation of my invention will be fully understood without further explanation. Y
What is claimed is:
In an automobile signal device, a cylindrical signal casing, front and rear walls for the casing bearing signal indicia, a yoke on the cylindrical wall of the casing outside of the casing, an incandescent bulb socket carried by the cross member of the yoke and extending through the cylindrical wall of the casing, said yoke permitting -access to the socket, an incandescent bulb within the casing in said socket, a second yoke having its legs secured to the legs of the rst named yoke and having its cross member parallel with the cross member of the first named yoke, said second named yoke forming a combined housing for the socket and a support for the casing, and a tubular member forming a conduit for conductor wires connected tothe cross member of the last named yoke.
