STOP-SIGNAL LAMP.

Application'led April 7,

ToaZZ whom t may Concern.'

. Be it known that I, PAUL A. STOVER,

,a citizen of the United States, residing at Racine, the county of Racine and State -ofl Wisconsin, have invented certain new and useful Improvements in Stop-Signal Lamps, 'of which the following is a specification.

. My invention relates tov improvements in lo stop signal lamps. f The general object of the invention is to provide a simple, economical construction. Another object is to provide an improved. socket for the lamp'. An additional object is tovr provide an improved bracket or adjustable support whereby the lamp may be readily mounted on different parts of the automobile, l.such as the fender, tail light bracket, spare tire rack, or other support, the bracket permitting the lamp to be arranged -horizontally and pointed rearwardly.

In the accompanying drawings I have A illustrated one embodiment of the. invention, in which- Figure 1 is a front elevation of the lamp;

2. is a sectional elevation thereof;.

Fig. 3 lis an enlarged front elevation of the lamp supporting plate;

Fig. 4 is a sectional elevation on the line of Fig.3; Fig. 5 isan elevation of one form Vof ad-v justable bracket;

Fig. 6 is asidev elevation of part of the same; i

Fig. 7 is 'an ,elevationofJa. 'modified' bracket; s 'f Fig. 8 shows how the lamp` may be mounted using the small bracket; and

Fig. 9 illustrates 011e use of the larger. bracket. i'

Thelamp comprises 'a parabolic casing 1, having a lens 2i inthe front thereof. Said lensv has the word Stop, or other .warning, formed by counter-sinking the letters below the inside surface Athereof .as shown in Fig. 2. The casing hasv an arm or bracket 3 secured thereto, by means of which it may be' adjustably mounted, as hereinafter explained. v

The incandescent lamp 4 is provided'with the usual base 5 having projecting pins 6 forming part of' a bayonet lock in' connection with the lamp support. i' Said support" is formed of Ia piece ofsheet metal?? hav- 1923. serial No. 630,657.

-up therefrom about a central opening, said flange havingk a pair of notches therein 'which extend-- radially into the plate, formin'g recesses "13 which receive the pins 6 on the lamp base.v Thelamp base' is inserted through the central opening and then turned a quarter turn to permit said pins to be snapped into a 'pair of radial recesses 14 by a resilient Contact member 15, which engages the center contact 16, of the lamp, and Vhelps hold said lamp in place. Said recesses 14 are pressedv into the rear. surface of said plate or lamp support 7. Said pins close oneside of the circuit, the other side being closed through said spring contact ystrip 15. Said contact is mounted on a Vbinding post comprising a screw 17 and nuts 18.. Saidscrew is-supported on -said plate but held out of contact therewith by means of fibre washers 19, 20, as shown in Fig. 4. Said Contact strip has a projecting rib pressed therefrom which fits a corresponding recess in the -fibre. washer 19,

1 thereby positioning said Contact centrally `of and behind the opening in'plate 7 and also preventing turning thereof with reference to saidtbinding post. A conductor 21 extends from the binding post through an insulating bushing22-in the sidewall of Vthe' casing.

The supportingL bracket shown in Fig. 5

comprises the arm 3 on the casing and a bracket 23 having openings v.24, 25, 26

' therein, and'having a bent up extension 27 at one end thereof. A bolt. 28 passes through openings in the adjacent parts and -is provided with a.lock washer 29. With v this .arrangement the bracket may-be swung through a considerable angle tol permit the A'lamp to be mounted on any convenient-part of the car. It is'shown in'Fi 9 mounted above 'the' tail light, the brac et 23 being clamped between the rear of said light .and

the-supporting member to which it is' atposition.

tached. Supporting the lamp iii this inaniier is made possible through the provision of openings 2li, 25 and 26 in the bracket 23, openings 24 and 26 receiving the ordinary rearwardly projecting retaining bolts of the tail light and opening 25 accommodating the centrally disposed electrical connector thereof.

A short bracket 30, Fig. T, may be substituted for the larger bracket, in case it is desired to mount the lamp on the fender, as shown ,in Fig. 8, for' example, or on the spare tire rack or other supporting frame.

It will be seen that the outer surface of the lens 2 is molded intoprisms forming what is known as a jewel surface. I tlius provide not only an improved lens construction but one having better photometric value or brilliancy. Said lens is held in p lace in the end of the casing by means of a split metal ring, as sho-wn in Fig. 2, permitting it to be rotated with reference to said casing. `Witli this arrangement, if it is necessary to mount the bracket 23 in hori Zontal position, the lens may be rotated so as to bring the word Stop in a horizontal In other words, a universal adg justment is permitted by the bracket and rotatable lens. If desired, said bracket 23 may be provided with notches 3l and 32, as

shown in Il`ig..5, whereby said bracket may be broken olf at this point and used in lieu of the bracket 30 shown in Fig. 7.

l. An automobile signal lamp comprising an outer casing open at one end, av lens closing said opening, a spring yoke securedl to the other end of said casing within the same, a supporting plate held in position by said spring yoke and a lamp mounted on said supporting plate.

2. A signal lamp comprising an outer casing.` a spring yoke secured near the center to said plate behind anopening therein but.

insulated therefrom, and an incandescent lamp having a base received within said Aopening and engaging said contact.

3. An automobile signal lamp comprising a casing, a curved strip of spring metal hav ing its ends bent to form catches and secured at an intermediate point to said casing, a metal plate having notches therein to engage said spring catches and having an opening with a struck-up flange surrounding the same, a pair of radial notches in said flange extending into saidplate to receive the radial pins of a lamp base, radial depressions in said plate on the side op-posite the said flange to receive said pins upon rotation of said base, a yielding contact member secured at the rea-r of said plate but insulated therefrom, a bottom contact on said lamp base engaging said resilient contact, a binding post electrically connected to said resilient contact, and a conductor eX- tending therefrom through an opening in said casing.

In testimony whereof, I have subscribed my name.

PAUL A. STOVER.
