This device relates to a sign or billboard and particularly to a sign or a billboard arranged to sequentially display a plurality of full-sized advertisements or other pictorial or printed displays.
While the principles of this invention will herein be described as applied to the type of billboard that is customarily used in' outdoor advertising, it will at once be apparent that the same principles may be applied to smaller signs for use indoors, in windows, and in other places.
The usual outdoor billboard is simply a flat surface upon which is painted a single advertising display. A plurality of advertising displays could be placed on a single billboard by reducing the size of each display but if this is done, the advertising value of each display is reduced by its reduction in size and is detracted from by the other displays adjacent to it. As a consequence, it is generally considered most feasible to place only a single advertising display on a single billboard, and preferably, to separate such a billboard from other billboards by an appreciable distance. This permits the advertising display to be on a large enough scale to attract attention and to be easily seen and understood even by those passing rapidly in some vehicle. It also avoids dividing the viewers attention between a number of smaller advertising displays.
In accordance with the present invention, it has been found that all of the advantages of a single and separate advertising display can be retained but that the location can be utilized for two, three or even more advertising displays, and that such extra attention may be obtained for these advertising displays as to make each of the plurality of advertising displays more effectively presented than the single display arrangements previously used.
This is accomplished in accordance with the present invention by the provision of an advertising sign, or billboard, or display, whichever it be called, that comprises a plurality of elongated rotatable members, each of which has a plurality of faces, at least two, preferably three, and possibly even more. One set of faces of the rotatable members is aligned to form a relatively continuous surface on which a display may be mounted in sections and the elongated, members are so arranged that they can be periodically rotated to bring another series of surfaces into parallelism. This second series of surfaces carries the sections which together form another display. By using three surfaces on the elongated members, it is possible to periodically rotate the members and to thus periodically display one after the other, three different advertising displays or signs.
The motion of this sign when it changes from.
one display to another attracts the attention of the viewer and thus each of the two or three or more advertising displays receives the viewers full attention.
Other objects and advantages will become apparent from a detailed description of the following specification when taken in conjunction with the drawings in which:
Figure 1 is a view in side elevation of the complete advertising sign;
Figure 2 is a view in horizontal section of Figure 1 along line 2-2;
Figure 3 is a view in side elevation showing the drive for the vanes and the timing mechanism;
Figure 4 is a view in horizontal section of Fig ure 1 taken along line 4-4;
Figure 5 is a view in vertical section of Figure 4 taken along line 55; and
Figure 6 is a schematic representation of the electric timing and controlling circuit.
Referring now to the drawings, Figures 1 and 2 show the completed advertising sign. It consists of a basic frame of L section structural members l0 bolted together to define a parallelepiped and intermediate members II and angles l2 for structural stability. The frame is supported above the horizontal plane by means of short I beams l3. Running lengthwise of the frame at its top portion is secured a channel member I4, as by welding, with its channel opening down ward. Mounted at spaced intervals along the member [4 in its channel are a series of thrust bearings l5 adapted to receive the end of a shaft. Similarly along the bottom portion of the frame is welded a second channel member l8, also running lengthwise and with its channel opening downward. The top of the member I6 carries a series of stands I! and mounted with each stand is a turntable I 8. The stands 11 are secured by Welding them in position. There is provided for each thrust bearing l5 2. stand I! and turntable I8 located opposite thereto. Supported on its end on each turntable I8 is a hollow prismatic vane [9. The other end of the vane I9 is provided with a rigidly mounted projecting shaft 2|] which fits into the respective thrust bearing I'5.
Each turntable is is bearing-mounted to 'a stand I! by means of a shaft (not shown). The details of this mounting will be considered in conjunction with Figures 3-5 inclusive. One end of 3 the shaft is rigidly attached to the turntable l8 and the other end is provided with a gear (not shown). A worm gear 2| meshes with each of the aforementioned gears. The worm gears 2! are mounted on shaft 22 at sufficient intervals to effect this purpose. Intermediate the worm gears are thrust bearings 23. The shaft 22 is connected to a reductor 24 which in turn is connected to an electric motor not shown. Also connected to the reductor 24 are cut-off and timing devices generally designated as 25. These will be described in detail in conjunction with the remaining drawings.
A mask is provided over the front, top, and sides of the sign by utilizing strips 26. This will serve to protect the sign from the weather and at the same time hide the working elements of the device so that a more pleasing effect is given to the matter being advertised.
In operation the vanes [9 are aligned to form a continuous surface upon which is placed advertising matter. Electricity is supplied to the motor and it drives the turntables it! through the reductor 24, shaft 22, worm gears 2 l, and the bearing mountings for the turntables l8. When the prismatic vanes I!) have rotated 120 degrees the motor cut-off 25 stops the electricity to the motor. At this moment each vane 19 has rotated one-third of a revolution. Inasmuch as the vanes 19 were originally aligned to form a continuous surface, they now in their present position aiso are aligned and present a continuous surface. This new surface, as the old, is covered with advertising matter. After a determined interval of time, one that is sufficient to give an individual a good opportunity to absorb the full significance of the advertising matter, the supply of electricity is returned to the motor. The vanes are then rotated one-third of a revolution and the operation just described is repeated.
Because the vanes I9 are all alike and of a prismatic configuration, they will present three distinct continuous surfaces which can be endowed with suitable advertising matter.
Figures 3, 4 and 5 show in greater detail the operating mechanism for the advertising sign. The channel member [6 as previously described serves as a base for the stands I! which are affixed thereto by Welding to one side or leg of the member !5. The stands 17 are flat plates of generally trapezoidal configuration. A bearing mounting is attached to each of the stands ll by means of bolts 3| and nuts 32. The bearing 33 is maintained in the mounting by screws 34. Placed directly above each bearing mounting 33 is a thrust bearing 35. Projecting through each bearing mounting 30 and thrust bearing 35 is a shaft not shown. By means of a built-up weld 36 each turntable I8 is attached to each shaft. Mounted rigidly on each turntable is is a threaded stud 3'! for the purpose of securing a prismatic vane I9. This is accomplished by placing a vane [9 having a concentric hole in its base surface on the stud 31 so that the stud projects through the hole. A nut 38 is then applied to the stud 31.
An additional feature of the turntables l3 and vanes I9 is that each is provided with an arcuate slot 39. When a vane 19 is placed on a turntable I 8 in the manner above-described, the slots 39 are aligned and a bolt 40 is passed through them. A nut 4! is put on the bolt 40. By means of this arrangement the vane H! can readily be adjusted in the event it becomes out of alignment with the other vanes [9, or it can readily be aligned in the first instance.
On each shaft holding a turntable l2 located directly below the bearing mounting 30 is a gear assembly consisting of a gear Gil and a gear hub and bearing 5!. The gear 60 is brazed to the shaft. Meshing with each gear 69 is a worm gear G2 mounted securely on a shaft 42. Inasmuch as the shaft 42 extends the entire length of the advertising sign it is necessary at spaced intervals to provide thrust bearings 43. These are fastened to the top surface of the member It by bolts 44. A flexible coupling 45 connects the shaft d2 with the driven shaft 46 of the reductor M. The driving shaft 48 of the reductor 41 is similarly flexibly connected to the output shaft 49 of an electric motor 50 by coupling 5i. A second driven shaft 52 of the reductor 41 is connected by gearing 53 to a shaft 54 upon which are mounted the adjustable time earns 55 and 55, of the timing and cut-off assembly generally designated as 5'6.
The basic frame as described in conjunction with Figures 1 and 2 consists of L section structural members H), intermediate members H, and angles 12. Additionally, masking strips 25 are provided for the purpose previously mentioned. At one end of the frame a base or table 19 is provided to support the motor 50, reductor 41, and timing assembly 55. The table 10 is attached to the basic frame by bolts H and nuts 72 which secure it to intermediate members H and the basic frame members It which structurally form the area immediately surrounding the end. Each of the several pieces of equipment carried on the table is is securely maintained there by bolting in a conventional manner.
Referring now to Figure 6 it will be seen how the timing device referred to in previous figures operates. The electric motor 50 is mechanically connected to the reductor 47 which is mechanically connected to shaft 54 by suitable gearing. The shaft 54 carries adjustable timing cams 55 and 55. A source of electricity is supplied to the motor 50 by means of leads BI and 82. Lead 8i is directly connected to the motor 50 and lead 82 is connected to one side of a switch 83 which is operated by cam 55. The other side of switch 83 is connected to the motor 50. A tap-off lead 84 from lead 82 is provided to one side of a switch 85 operated by cam 55. The other side of the switch 85 is connected to one side of a suitable timer 86 and to one side of a switch 81 operated by a cam 83 driven by the shaft 89 of the timer 86. A lead is connected to the other side of the timer 85 to provide a return through lead 8 l. The other side of switch 8'? is connected directly to the motor 50.
The timing device operates in the following manner. Initially the vanes 59 are aligned and not moving. The switch 33 is maintained in closed position by cam 55 and the switches 85 and 3? are held open by their respective cams 55' and 33. When a source of electricity is provided, a complete circuit through leads. 8% and 82 and switch 83 enables motor to operate to turn vanes l8 and shaft 54 through reductor 41. When the vanes l9 have rotated degrees, the cams 55 and 55 which are correlated to vane motion react as follows. Cam 55 now has been suffici ntly rotated by shaft 54 so that it holds switch 83 open. This stops the motor 58. Simultaneously, cam 55 has been rotated so that it now holds switch 85 in a closed position. As a result of this activity the motor 59 has stopped. The vanes 49 have also stopped rotating 120 81. As the motor 50 turns, its movement is transmitted to shaft 54. As the shaft turns, cam 55 immediately closes switch 83 and cam 55' immediately opens switch 85. At the same time the timer 86 has rotated the cam 88 by means of shaft 89 to such an extent that the cam 88 now holds the switch 81 in an open position. The timing device is now in its initial position ready to repeat the operation.
It is to be noted from the foregoing that the advertising sign has been so designed that it is readily susceptible to being disassembled. In this manner it can be transmitted from one point to another easily by shipment in its unassembled condition. Consequently, it can therefore be assembled economically at the point of erection or use. The sign is capable of being disassembled by reason of the use of bolts throughout. Additionally, all the shafts are provided with connecting couplings at suitable points to permit their being taken apart.
The electrical timing device as hereinbefore described is subject to modification in the event that it is desired to coordinate neon or other electrical effects with the rotation of the hollow prismatic vanes. Additionally, the timing device can be made adjustable to different stopping and starting sequences.
While this invention has been described in conjunction with a single embodiment, it is, nevertheless, to be understood that various changes and modifications obvious to one skilled in the art are within the scope, spirit, and contemplation of this invention.
