My present invention relates to advertising signs, and more particularly tovan advertising sign for use on aeroplanes;

Advertising signs for useonthe Wings of' jaeroplanes, as heretofore constructed, have been impractical for a number of reasons.Y

One'of the Objections is due to the fact that the signs have not been completely interchangeable. Another ,objectionl has been thatfthe signs havef'not'conformed to the lines ofthe vaeroplane Wing, thus interfering with the `speed of t-he aeroplane,

My invention isran improvement on the ade vertising'sign patents of .Mitchell and La Grasse, No. 1,474,682, La Grassa, `l\los,.V

Another Object of the invention is tog provide a sign Which Will substantially 'conform 'v to the lines of the Wings ofvtheaeroplane, so that the surface Vof the sign'vvillfjbe flush- With the surface of the, Wing.

A stillfurther object of the invention is to" provideV a sign of this type Which can be readdraWing, in' Which l Figurel isaview of the undersurface of avv portion of therme-2 2 of Figure isa longitudinal cross sectionofV a fabric-'covered aeroplane W1ng showing panels Willbe completely interehange-v Figure is @view Y0f lumilieli Vapor. tbe' formed into aletter and particularly adapted for use With aeroplanes,

Figure 8 is a cross-sectional view taken on the lineA 9--79` of Fig.7, and

Figure 9 is a sectional View, similar lto Fig. 8, showing-the method of attaching the signY panel shown yin Figs. T and 8 to a fabric-coveredV aeroplane Wing. v i l `In the form of the' invention shown in Figs.` 1 to3, the numeral 10 designates the lower Wing of an aeroplane the fulage of which is indicated by the numeral 8O. Luminous Vapor tubes 23 formed to the outlines of. letters are shown attached to the lower surface of the Wing 10 `by means of clamps or brackets 14, The clamps or brackets 14 are generally U-shaped so as to conform to the outline of the tubes 11 and `are' provided vwith 4ears 35 adapted to` bear against the -ied i'nto Vnuts 29Vca`r'ried in slotted. Ways 1i',

As shown in Figi4 1 groups slotted ways 12,- 13, and 15 a'raprovided on the lower surto hold a singleletter tube 11', Order that neiv letter tubes'may'be aiiixedfto each group of slots or letter position, it 'ispreferable yto provide several longitudinally extending slots 12, an upper central' slot 13, an upper corner slot 13", a lower' central slot 15, and aflovver cornerA slot'157. t

As has been stated above, in order to hold Sign letters-uren the Wugathe bolts 28 @X- t-end th@ S10-tis." 181. 13,. and 15,7 naccord'an Wththe Outline Oftheletters'w besecued, 'and engage ,the mits 29- Thenuts 29 are held in alignment with the slotted ways 12, 13, 13, and 15 by means of the plates 16 which are secured to the inner surface of the under side of the wing by means of set screws 1S. The plates 16 are provided with a central groove 17 in alignment with the slots 12, 13, 13, 15 and l5, the groove 1T being so shaped as to prevent rotation of the nuts 29. A number of nuts snflicient for all purposes may be placed in the groove 17 of the plate 16 when the plane is constructed, or at any time thereafter. When a letter tube Q3 is to be attached to the wing, it is merely necessary to slide the nuts 29 to points where they will be in alignment with the positions which must be given the bolts 28 and clamp 14 to secure the desired letter to the wing. rlhe bolts Q8 will then be tightened to draw the clamp 14 securely against the letter tube 11. Y

It is believed that the showing in the drawing of the arrangement of the clamps 14 for attaching the letters A, E, R, O upon a. plane will clearly indicate the various positionings of the clamps which must be worked out to secure various letters of the alphabet.

In order to supply current to the luminous letter tubes 23, a group of contact sockets 27 is provided with each group of letter-positioning slots 1Q, 13, 13', 15 and 15. By providing a plurality of sockets 27, it will be possible to supply current to a tube formed into any letter. The tube contact plugs 92 are flexibly secured to the tube by means of wires 91 of opposite polarities leading into the rear face of the tubes at two points as is customary in sign letters of this type. Electric current may be supplied to the sockets 27 'from a generator or any suitable source upon the aeroplane.

In Fig. 4, I have illustrated a fabriccovered aeroplane wing 19 to which luminous letter tubes may be attached in much the same manner as has been described above. Brackets 14 will be secured to the aeroplane wing by means of screws 34 extending into the spars 20 of the wing. In the event that the spars 2O are not sufficiently close together to accommodate the desired number of letter tubes. additional spars or cross members 22 may be built into the wing 19. y

In Figs. 5 and 6, I have illustrated a forni of luminous sign letter tube which is particularly adapted for use on aeroplanes. For the purposes of showing my invention, I have illustrated it as applied to the letter A. However, it will be understood that it may be used in the construction of any luminous letter tube. In forming the tube, the upper edge of the upper portion 24 of the letter is tapered down on its upper or exposed side. The under surface of the letter tube (the surface which contacts with the aeroplane wing) is made substantially flat. This arrangement results in the provision of a knife edge on the portion of the letter facing in the direction of flight of the aeroplane and thus cuts down wind resistance. The trailing edge of the letter tube 26 may also be streamlined, as shown. In forming the letter' A it will of course be understood that the entire outer and upper edge 25 of the letter should preferably be streamlined, thus avoiding the wind resistance which might occur if the sides of the letter were formed in the usual manner.

In Figs. 7 and 8, I have illustrated an arrangement for attaching sign panels or letter panels to the under surface of the lower wing of an aeroplane in such a manner that the surfaces of the panels will be flush with the surface of the aeroplane wing. The numeral 40 designates the lower wing of a metal aeroplane. Letter panels 41 are secured to the under surface of the wing 40 by means of set screws 43. As shown in Fig. 8, the side edges of the panels 41 are angled or olf-set, as indicated by the numeral 49, so that they may be fitted into slide Ways 44 extending from the front to the rear edges of the aeroplane Wing 40. The set screws 43 extend through the olf-set portions 49 of the letter panels, so that the latter are securely held in position.

The panels 41 are preferably formed of metal sufficiently flexible to conform to the curving outline of the aeroplane wing, and the letters 47 outlined in the panels 4l are preferably formed of Celluloid, so that they will be flexible as well as translucent, although the letters may be formed of sections of glass so arrangedas to give the desired flexibility. The Celluloid orglass or the like may be held in place in the panels 41 by means of clamping plates secured to the lower surface of the panels by screws 61. Light bulbs 46 are mounted in reflectors "45 beneath the panels 41 so as to illuminate the letters 47. Electric current to illuminate the bulbs 46 may be supplied from a generator or the like carried on the aeroplane.

In Fig. 9, I have shown an arrangement for securing letter panels to fabric-covered aeroplane wings. It will be seen that the panelsr41 are secured in exactly the same manner as is described above in connection with Figs. 7 and 8, except that the edges 49 of the panels are mounted in spars or additional. cross pieces 48. The light bulbs 46 are mounted upon supports 5() extending between the spars or cross pieces. Reflectors may be provided if desired.

I claim:

1. The combination Vwith an aeroplane wing, said wing having a plurality of slots in the surface thereof and arranged in an angularly disposed group, of a luminous letter tube, removable securing elements adapted to secure said tube against the surface of the wing, said elements being selectively positioned in the slots of said wing, and an electric socket for supplying current to said tube.

2. The combination with an aeroplane Wing having a plurality of slots in the surface thereof and arranged in angularly disposed groups, of an outline sign letter adapted to be placed against the surfaceof the Wing and means adapted to secure the letter to the Wing Comprising brackets selectively positioned in the Slots in the Wing surface.

3. Tlie combination With an aeroplane Wing, said Wing having a plurality of angularly arranged slots therein, of a letter and movable elements' adapted to secure said letter to the Wing, said elements being selectively positioned in the slots in said Wing.
