SIGNAL LAMP.

Application filed March 28, 1924. Serial No. 702,531..

To all whom it may concern:

Be it known that I, NEIL T, ALBRIGHT, a citizen of the United States, and a resident of Kokomo, county of Howard and State of Indiana, have invented a certain new and useful Signal Lamp; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings in which like numerals refer to like parts.

This invention relates to a combination stop and direction signal to be mounted on the rear of a vehicle and electrically illuminated for signal purposes. However, the invention resides" only in the peculiar featuresof the signal as herein claimed. Heretofore signals of this character have been constructed having oppositely directing ar-' rows, or the words Left and Right or abbreviations thereof in combination with an individual and separate stop or caution signal, all three, i. e., the stop, left and right signalsbeing'operated independently of each other and entailing three separate compartments having three separate bulbs for illuminating the individual signals.

It is the object of this invention to provide a signal of this character eliminating one of the three compartments, bulbs and signals by employing direction arrows or similar direction indicating signs which may be illuminated separately or independently of each other as desired, and'combining the two by illuminating them both simultaneously for providing and giving a stop or similar signal.

as to operation, cost and reductioninspace, as will be 'hereinafter more fully pomted out.

Another feature of the invention residesv in the means for controlling the signal,

whereby thedirection signals may beoperated manually when it is desired to makea turn, whilethe stop or warning signal may cast in two pieces and assembled for providing the desired outline, partitions and This construction will obtain cer-. taln advantages over the old structure both lamp sockets, as illustrated in the drawings and hereafter more specifically described.

The full nature of the invention will be understood from the accompanying drawings and the following description and clalms:

In the drawings, Figure 1 is a diagram matic Illustration of the control system. Fig. 2 is a front elevation of the assembled lamp. Fig. 3 is a section taken on the line 33 of Fig. 2. Fig. 4 is a front elevation of the assembledmembers without the lens or door mounted thereon. Fig. 5 is a front elevation of the outer member. Fig. 6 is a front elevation of the inner member. Fig. 7 is an end view of the inner member as shown in Fig. 6.

In the drawings there is shown an automobile signal lamp comprising a housing 10 shaped as shown 1n Fig. 5, the same having an open end which is closed by the closure 11 securing the lens 12 thereover. The rear of the housing is provided with a screw threaded projection 13 on which a cap 14 is screwed for securing the conduittube 15 in place.

The casting comprising the housing, as shown in Fig. 5, is provided with an aperture .16 which is surrounded by the screw threaded projection 13, -andfis formed on the inner surface with inwardlyprojecting lugs 17, 18 and 19 provided midway their depth with recesses 20, 21 and 22, into which or against which the insert partition member 23 may be seated and held in place.

The insert member 23 is likewise cast of suitable metal with a back closure 24, the sides thereof providing the shape of the arrows, as shown in Fig. 6, with a partition wall 25 separating the arrows and joining with the partition wall 26, which separates the arrows from the lower portionor taillight compartment 27 Cast in the tail-light compartment there is a lamp socket 28 and cast in each of the arrow sections there are lamp sockets 29 and 30.

In assembling the insert member 23 into the casing,.the points 31 will seat in the recesses 20 and the points 32 will seat in the recesses 21, whereas the ends 33 of the casting will abut the recesses or shoulders 22. It will be further observed that the socket 28 will be in alignment with the aperture 16, and that upon securing the lens and door to the left.

11 in place, the insert member will be held firmly in position, thereb giving desired outline effect of the oppositely directed arrows and the tail-light compartment, as shown in Figs. 2 and 4.

In the operation of the signal, reference being had to Fig. 1, there is provided a hand operated switch 38 having a left contact and a right contact. The switch member 38 is connected with the ignition switch 39. The left contact is connected through the wire 40 with the bulb 35 and the right contact is connected through the wire 41 with the right bulb 36. The ignition switch 38 is connected through the wire 42 with the automatic switch 37 operated by either the brake or the clutch, said switch being connected through the wires 43 with the re spective bulbs 35 and 36. bulb 34 is connected with the tail light circuit in the usual manner through the wire 44.

When the operator wishes to make any turn, he manually turns the switch 38 to the direction to be taken. This will be illustrated by assuming that he desires to turn He accordingly turns the switch to the left as he is approaching the turn. This will cause contact to be made from t e i direct y to the bulb 35 and will illuminate the bulb and the compartment defined by the left direction indicating arrow. As he slows down to make the turn, by either' throwing out his clutch or putting on-his brake, a current will also pass from the ignition switch through the line 42, switch 37 and wires 43 to both lamps 35 and 36, thereby illuminating both of the arrow-like compartments. This will indicate the stop signal or other warning signal by reason of the added illumination throughout the entire width of the lamp. Upon releasing the brake or clutch to make the turn, the stop signal will be shut off, or rather both arrows will cease tobe illuminated, but the left turn signal will remain illuminated until it is manually switched off by the operator. If it is desired to slow down or make a stop without making a turn, the operation of. the brake or clutch will illuminate'both lamps 35 and 36, thereby flashing the entire expanse of signal lamp and giving the warning signal. i

The above example is only for purpose of illustration, it being apparent that other arrangements for controlling a lamp of this V The tail light ition switch through the wire 40.

character may be employed without departcasing and insert casting being provided with interengaging means whereby the latter is supported within theformer, and snugly seated within said casing a'transparent closure removably secured over the open face of said casing, and individual means in each of said arrows for illuminating the same, whereby said illumination will be apparent through said closure in the outline of the respective combined arrows, substantially as shown and described.

cast integral with a back portion and an open face, said back portion having an aperture formed therein, a plurality of .inwardly extending projections formed in said casing, an insert casting forming a plurality of compartments outlinedin the shape of oppositely directed arrows, said casting being adapted to fit snugly within said casing and be seated and held in posit-ion by said projections, and a closure removably secured over the open face of said casing for securing said insert casting therein.

3. A signal lamp comprising a casing cast integral with a back portion and an open face, said back portion having an aperture formed therein, a plurality of inwardlyeigtending projections formed in said casing, an insert casting forming a plurality of compartments outlined in the shape of oppositely directed arrows, a compartment being positioned below the direction compartments for receiving a tail light, said casting being adapted to fit snugly within said casing and be seated and held in position by said projections and spaced from the NEIL T.
