r:SIGNAL LAMP Filed July 5, 1929 WWNESS: ATTORNEY Patented Apr. 7, 1931 UNITED STATES MARK E. JOHNSON, 0F HABRISBURG, PENNSYLVANIA SIGNAL LAMP Application filed July 5, 1920. Serial No. 376,036.

The present invention relates to direction signals for automobiles, and contemplates;` `a novel signal lamp construction adapted to be mounted upon the fender of the machine so that it can be viewed from either end thereof, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawing forming part of this application like numerals of reference indicate similar parts in the several views, and wherein Figure 1 is a vertical sectional view through the signal. y

Figure 2 is a fragmentary longitudinal sectional view.

Figure 3 is a vertical sectional view.

The lamp casing or body of the signal is indicated at 10, and while the latter may be made from any suitable material and also vary in size and configuration without departing from the inventive idea, it is preferably of cylindrical contour in cross section and open at both ends. The casing 10 is formed with an integral base 11 adapted to be mounted on some appropriate part of the vehicle, preferably the fender indicated at 12 and secured thereto by means of suitable fastening bolts 13. Each end of the casing 10 is provided with a lens 14 of hollow formation, and formed with a flange 15, while directly behind each lens is a reflector 16 also formed with a marginal ange 17. Interposed between the flanges of the lens and their refiector is a gasket 18, while arranged between the flange 17 of each reflector in the adjacent end of the casing 10 is a similar gasket 19.

These parts are all held associated by `means of a retaining ring 20 which surrounds the casing 10 as illustrated, and which is also formed with an inwardly directed flange 21` arranged directly in advance of the flange 15 forming part of the lens.

Interposed between the flange 15 ofV the lens and the inwardly directed flange ofthe retaining ring is a gasket 22. While the retaining ring 20 may be held associated with the casing in any suitable manner, it is preferably formed with a projection adapted to be received by a bayonet slot 23 formed in the casing 10. Each reflector 1G supports an` electric light bulb 211. It is of course7 `to beunderstood that there is one of these `signal lamps mounted on eachffender of the vehicle, the front lens being green in color, while the rear lens is red, thereby adapting thesignal lamp as a direction signal for the movements of the vehicle as well as permitting of its use in the capacity of a parking light or lamp. The signal lamps are, of course, operated in pairs at either' side of the machine, to indicate when the driver of the latter intends to` turn to the right or to the left,` or to bring his machine to a stop, and consequently the lamps can thus be selectively illuminated in pairs by means of a suitable switch,.not herein illustrated.

Arranged within the lamp casing 1() and mounted upon the base 11 is a block of insulating material indicated at 25, which supports the contacts for the respective bulbs7 while depending from this block 25 is a sleeve 26 which passes thru a bore formed in the base 11. The contacts for the respective bulbs are indicated `at 27 each being formed with an offset extremity 28 which engages one end of the block 25, while passed through this block and connecting the offset extremities of said contacts is a pin 29, A signal conducting wire 30 is used, being passed through the sleeve 26and connected to one end of the pin 29 as illustrated If desired a suitable guard 31 may be arranged beneath the fender to protect the wire 3() .i

frombeing damaged by antiskid chains or the like.` i i y i As above stated there is one ofthcse lamps arranged on each fender of the machine. and the lamps can be selectively illuminated in. pairs at either side of the machine depending of course,` upon the direction to be pursued by the machine. The current passing through the wire 30 to the contact 27 through the pin 29, simultaneously illuminates both bulbs in each lamp, thereby giving a green signal at the forward end of the lamp and a red signal at the opposite end thereof. As above stated when the machine is at rest one of the signal lamps can u Sli * forming casing,

be used as a parking lamp, and the electrical connections between the various lamps can be made 1n accordance with well known present day methods.

While it is believed that from the foregoing description the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when `desired as fall within the scope of what is claimed.

What I claim is Y l. AV signal of the character described comprising a lamp casing open at one end,

and having a bayonet slot adjacent thereto,

said casing including an integral base there-v for, a lens for thecasing, a flange Jformed on the lens, a reflector arranged within the l casing and formed with a marginal flange, a gasket arranged between the respective flanges, an additional gasket arranged between th'e flange of the reflector and thevadjacent end of the casing, Va llanged retaining ring for the endof the casing, and including a. projection received by said slot for holding the reflector and lens associated with the casing, a gasket arranged between the flange of theretaining ring and the flange of the lens, and an electric light bulb supported by the reflector.

2. A signalof the character described comprising a base, a cylindrical lamp casing an integral part of the base and supported upon the latter, a lens for the a reflector arranged within the casing, an-electric light bulb supported by the reflector, a block of insulating material supported upon theV base, a contact'carried by the block, and a 'conducting wire passed through a bore in the base and terminally connected with the contact.

3. A signal of .the character described -comprising a base, a lamp casing forming an integral part ofthe base and supported 1 thereby, reflectors arranged within the casing, a lens foreach reflector, a block of insulating material supported upon the base and located within the casing, electric light bulbs for vthe reflectors, a pair ofv spaced contacts .supported by the'block, a single transverse pin passed through the block and connecting said contacts', and. a conducting -wirepassed through a bore in the 'base and terminally connected withKV one end of the pin vfor the purpose specified.

In testimony whereof I afilx my signature.` v MARK E. JOHNSON.
