ADVERTISING DEVIIQGE.

Application med niy 23, 1 s24,se'r ia1 No. 727,817, andl in 'the Netherlands nay 1o, 1924.

This invention relates to advertising devices.

The object of tlie'invention is to provide a method of and apparatus for advertising. 5 According to the present invention advertising pictures or the-like, either `stationary.

or moving, are pro'ected onareceiving sur- `face mounted on. oard a boat, on which additionally the whole available spacey may be utilized for the purposes of advertisements with or without artificial light. i

This boat is adapted to be' stationary or to cruise about at or between speciallyse- 'lected points such as bridges, ports, landing ,stages and other large centres of traic.

The invention further comprises various constructional arrangements. applicable to the boat fitted up with the object hereinbefore mentioned.

L` One example of construction is illustrated ld'1a.grammatically with reference to the accompanying drawings, in which:` Figure 1 is a side view;m Figure 2 is a plan view. .Y Figure 3 a front view of a.boat intended for advertising purposes according to the invention.

Figure 4 is a section on the line IVe-IV of Fig. 3. y l

Figure 5 shows an arrangement for stopping or fixing the advertising screen. Figure l6 is adiagrammatic section 'on an enlarged `scale of the projecting cabin.

The boat consists of a hull 1 in' the front ofwhich is mounted a screen 2 for projections whilst towards the middle there\are provided the living cabins Sand at the rear the projecting cabin 4.

It is desirable to arrange the screen 2 to 40 extend to a great height because then the pictures which are thrown thereon are more easily visible. The projecting apparatus must in this case, be arran ed'at an equal height. On the other han itis desirable to enable the upper members vto be lowered when inoperative in order that the boat may easily pass beneath low bridges and also in order not to detract from the monuments of the towns. This object is realized in the form of construction illustrated in the following manner:

The screen for receiving the rojections is carried by two upri hts 10 whic are movable on a shaft 9 an to the base of which are fixed toothed sectors 11 with which pinions 124 mesh. The two 'pinions 12 are wards the front whilst above the screen an mounted on a common shaft 120 which, by

.means of toothed wheels and a worm or like wheel are given a rotary movement by means of a worm 13 to which is keyed a hand wheel 14. When the screen has reached its topmost position a pawl 16 shown in- Fig.v 5 engages in ,the teeth of a stop plate 15 mounted -on the upper part of the worm 13. The pawl 16 is operatedagainst the' action of a spring 160 by means of a traction rod 17 -which is pivoted to the end of a bracket 18 mounted on the shaft 9. The axis of the worm may however, be.stopped in any suitable manner.

The exhibition 'screen preferably consists of a dulled or ground `lass mirror 19 the dulled surface of which 1s turned to the front where it is protected vfor some distance by a sheet of glass 20 to prevent the dulled face 'from becoming moist. It is however, ossible to throw pictures on to a prepare or unprepared canvas or on to a'sim ly dulled sheet of glass, the dulled face of which isv coated with a transparent material impermeable to water such asfor instance, paraiin. The side walls of the uprights'of the projecting screen are occupied by advertising panels 21 which are preferably placed obliquely toautomatic time indicator 22 is arranged. Ay frame is provided all round the screen which frame may be utilized for advertisin purposes and/or ornamenting the whole. glu the raised osition the screen may be held by cables xedto the hull,-which are not shown.

Beneath the screenbetween the uprights 10 is arranged an advertising panel 23 pivotal about a horizontal axis 24. The ob'ect of this is to enable the advertising pane 23' to be turned whenA the screen is lowered so that then'the rear face of the panel comes to the top vand the front face is .protected from any deterioration. Y

The rotation `of his advertising panel 23 may, it necessary, be effected by hand after which the advertising panel is maintained in any desired position. The rotation may to cause the latter to rotate about an axis during projection of the advertising matter so that the two faces are successively presented to the front.

If necessary, the living cabins may be rendered accessible from the front by means of a tunnel 260 which facilitates access beneath the advertising panel 23.

In plan view the cabins 3 have the form of a trapezium, the side walls above thev deck being utilized for placing fixed advertising panels 27 and 28 connected for example by hinges. The panels 28 may be folded down against the panels 27 so that the panels mutually protect one another.

The cabin 4 is formed as shown by three telescopic elements 29, 30 and 31 the'lower element 29 of which is Xed to the hull or body of the ship and is partially prolonged above the deck. The desired i of the cabin 31 upwards and downwards is obtained by an-extensible member such as a lazy ton s device the two fixed points 35 and 37 o which are respectively connected to the hull 1 of the boat and to the cabin 31 whilst the two movable points 36 and 38 may slide along slide pieces 32. and 33 the first of these latter being connected with the hull 1 and the second with the cabin 31. The points 38 may for example be displaced by means of helicoidal screws having an automatic brake whilst the helicoidal screwsV may in their turn be actuated by means of screw wheels, pawls or like members. All these parts are well known and are therefore not shown. Between the elements 29, 30 and 31 there are rollers 39 which facilitate the telescopic movement whilst the element 30 is raised by the element 31 by means of abutments 300 and is itself arrested in'a raised position by the element 29 by means of abutments 290.

To ve access to thecabin 31 one of the four sldes is free preferably vthe front `face which is turned towards the projection screen. One of the other sides may also be utilized for the same object. A door 42 three doors coincide so that from the deck splacementA when' the elements are telescoped one inthe other no water can penetrate therein. Finally in the cabin there is a projecting apparatus 45 by means of which the desired pictures may be thrown on to the screen 2. The walls of the elements 29, 30 and 31 which are not utilized for the cabin and the doors are occupied by advertising panels. In the walls of the cabin openings 310 for light and, air may be provided. In the raised position the cabin may be supported on the hull by means of cables which are not shown in the drawings.

As the weight of the screen is considerable i the lowering and raising of the same causes a considerable displacement of the centre of ravity. Ballast tanks 5 and 6 are thereore provided at the front and rear of the boat 1 which tanks are in adjustable communication with one' another' and with the outside bymeans of a pi e 7 and a pum 8. The pump 8 ma also e utilized as a bllge pump for the ot er spaces.

Dependent on the raised or lowered position of the screen its weight acts on the bow and the centre of the boat respectively. In both cases the horizontal position of the boat may be maintained by causing an exactly predetermined quantit of water to ass from one tank into t e other. The at may be caused to be more deeply immersed b introducing more water into both tanks. 'Ilhis ma be of advantage for passing under low bri ges. v The surface available for advertising may be also suitably increased by providing the parts locatedabove the deck such for example as the screen, the projection cabin and the dwelling cabins or some of them with an arrangement for sup orting a canvas which may be utilized for adyertisements.

If desired an arrangement for causing the boat. An arrangement of this kind may, v

for instance, be formed b a loud speaker, a megaphone or a device o this type.

When the screen is lowered its advertising surface is covered -in an impermeable manner. The screen then rests on the roof of the cabins 3. 'A h Various other forms, of construction come within the sco e of the invention. The displacement of t e screen may for instance be effected by means of awmch and a steel cable on each upright. Further the screen for the advertisements may be made movable between the uprights with the object of, being able to bring it nearer to' the axis of rotation during the'v rotary movement of raising and lowering it and thus to diminish the momentum.

Finally the whole screen may be caused to descend vertically into the boat whilst a combination would also permit ofrendering the frame of the screen telescopic `and at the same time lto enable it to be turned about a horizontal axis.

The cabin may also be constructed in various ways. Itmay for instance be raised by means of one or more Winches, with steelcable or one or more screw cranes. The Whole may also be constructed of three cylinders', the two outer ones of Which are provided on their inner faces with three or a larger number of helical guides in which thel two inner cylinders arranged inside are displacedon rollers so that the latter can be raised by means of small Winches With steel cables.

Finally the cabin may be suspended to one \or more masts or the cabin maybe arranged on uprights raised on hinges which maybe caused to rise or fall by means of Winches or toothed sectors. Between these uprights ladder posts may be fixed. It is nally also possible to keep the projection cabinA in the lowered position and to throw the pictures on to theelevated screen by means of a perisrzfpe which is partially or entirely remova e.

What I claim is:

A boat arranged for advertising purposes including a receivin apparatus for projecting advertising pictures Ieither stationary -or moving onto-said screen,

,a telescopic cabin containing said projectin apparatus, means for raising saidcabin hi above the deckvor lowering same into t e body of the ship and means for movably screen, a projectingmounting said receiving screen opposite said cabin comprising a su portin capable of being lowere onto t the boat.

{In testimony structure e deck of whereof I have hereunto set my hand.
