Y. Application November 9, 1937, Serial No. 173,573 9 Claims. (CI. 40-52) This invention relates to signs and particularly to an improved movable changeable electric sign, an object of the invention being to provide a construction which will present a picture or other attractive means adjacent a movable sign struc ture. Another object of the invention is to provide a sign construction having an endless sign belt adapted to be moved uniformly or intermittently in connection with a slide having a picture there 10 on adapted to be moved into and out of view as the sign belt travels. . A further object is to provide a sign belt and attractive structure associated therewith, to— gether with means for producing a sound con tinuously or intermittently to attract attention to the sign structure. An additional and more speci?c object is to provide an electric sign having an endless belt formed with means for removably receiving 20 letters or other sign indicia. In the accompanying drawings-— Figure 1 is a front elevation of a movable changeable electric sign disclosing an embodi ment of the invention; 25 Figure 2 is a vertical sectional view through the structure shown in Figure 1, the section be ing taken on the line 2-2 of Figure 3; Figure 3 is a sectional view through Figure 4, approximately on the line 3—-3; 80 Figure 4 is a transverse sectional view through Figure 3, approximately on the line 4-4; Figure 5 is a fragmentary view showing part of the belt illustrated in Figure 2; Figure 6 is a section through Figure 5 ap 35 proximately on the line 6-4; Figure 7 is a fragmentary sectional view through Figure 3 on the line '|-—~'l; Figure 8 is a diagram showing the Wiring of the 40 various parts of the sign; Figure 9 is a fragmentary view showing an intermediate drive embodying certain features of the invention. Referring to the accompanying drawings by 45 numerals, i indicates a casing or housing of any kind, which may be wood or other suitable ma terial, and in which is housed the various mov able parts of the device except the hammer 2 of the sound-producing device or vibrator 3. This 50 hammer 2, as shown in Figure 2, is adapted to strike the window I! in which the device is placed though it could be made to strike some other particle without departing from the spirit of the invention. It will be understood that this 65 soundeproducing device is caused to function either continuously or intermittently as may be desired. The housing I is providedwith a front door 5 which may be hinged or otherwise secured in place and which is formed with a glass panel 6 which at the top and bottom is provided with a coating of paint at diiferent places to make the same opaque, but the glass 6 itself is transparent and, as shown in Figures 1 and 2, the portions 1 and 8 are left uncovered so that an object may be seen therethroughv The portions 9 and Ill, however, are covered with paint or other opaque substance. By reason of the fact that the por tions 1 and B and also the portion ii are not covered, windows are presented through which the sign l2 of the belt 13 may be seen, and also windows are presented through which the re spective ?gures ill and i5 are visible. As shown in Figure 1 of the drawings, the ?gures l4 and I5 represent parts of a man with his hand pointing upwardly, but these ?gures or members could represent other things without departing from the spirit of‘ the invention. As hereinafter fully described these pictures or ?gures are moved into and out of view as the de- 2 vice functions so as to attract the eye of a passerby. It will be seen from Figure 2 that the belt l3 is an endless belt and has one or more signs 12 thereon which are brought to View from time to time as the device functions. If de sired, an electrically actuated clock It could be 0 arranged centrally of and above the housing I. A hooded lamp I’! is arranged immediately above the clock so as to illuminate the same. While the clock 16 is preferably electrically actuated it 3 may be a spring-actuated clock without depart ing from the spirit of the invention. As shown in Figures 2 and 3, the endless sign belt [.3 is mounted on four rollers, namely, l8, l9, 2!], and 2|. The rollers 2E! and 2! are ?xed but 40 freely rotate and, in fact, are driven by an end less sprocket chain 22. Suitable sprocket wheels 23 are rigidly secured to the respective rollers and, therefore, whenever the chain 22 functions all of the rollers will move or rotate in the same direction and at the same speed. The chain 22 passes over a small sprocket wheel 23 near the lower end of the device, said small sprocket wheel being rigidly secured to a stub shaft 25'. An idler 25 is adjustably mounted by reason of a slide 21 and screw 28. This permits an adjustment of the tension of the chain whenever desired. The rollers 20 and 2! as mentioned are ?xed but the rollers l8 and it are vertically adjust able as illustrated more particularly in Figures 55 2 2,120,809 3 and 7. From these ?gures it will be seen that the rollers l8 and I9 are rotatably mounted on bars 29 secured to vertical sliding blocks 39 and 3|. A bar 32 is connected with the housing I by suitable screws or other desirable means. This bar carries a right angle bracket 34 and the bar 29 carries a similar right angle bracket 35. An adjusting screw 36 has a reduced end 91 rotatably mounted in the bracket 35 while it is 10 threaded through the bracket 34 and locked in desired adjusted position by a suitable nut 38. Angle bars 39 and 40 are also pivotally mounted at 4| and 42 on the bar 29. These angle bars are adapted to swing over to the position shown in 15 Figures 3 and 7 so as to prevent longitudinal movement of the rollers I 8 and l9. It will be observed that the pins 43 of the respective roll ers I8 and I9 extend into suitable apertures in the bar 29 and can not move to the right, as shown in Figure 3, by reason of the housing I. However, there is provided a socket 44 at the left so as to permit a left-hand sliding move ment of the rollers when the angle bars 39 and 40 are moved out of engagement. This is to al 25 low the rollers to be applied or removed. The lower rollers 20 and 2| are likewise pro the outer end of shaft 56 is journaled in the upper end of a bracket 6|, while the lower part of bracket 95 acts as a journal support for the shaft 69. A small bevel gear 62 is rigidly se cured to the upper end of shaft 69 and contin uously meshes with a larger bevel gear 63 which is rigidly secured to shaft 25. By the construc tion just described the shaft 25 is rotated at a comparatively slow speed even though the mo» tor 55 operates at a comparatively high speed. 10 As the gear 5! is larger than the gear pinion 59, the pinion will operate at a higher speed than shaft 25 though sprocket 24 will operate at the same speed as shaft 25' and, therefore, will con tinually move the belt l9 when the motor 55 is 15 functioning. However, from Figure 9 it will be seen that a slightly modi?ed construction is used wherein the gear 5i secured to shaft 25 is a mutilated gear and has comparatively few teeth 64 which upon each revolution engage and 20 move the gear wheel 59’, thus producing an in termittent movement of the gear wheel 59’ and an intermittent movement of the sprocket chain. Immediately back of the front transparent plate 6 there is provided a slide 65 which is 25 formed with a plate 66, which may be formed of vided with pins 45 extending into bores in the supporting plate 46. At the opposite end re spective pins 45' extend into the supporting plate 4'! and may be slid into the bore 48 when it is glass, celluloid, or other transparent material and which is preferably translucent but provided with opaque sections 61 and 68. These opaque desired to remove the lower rollers. Each of the lower rollers at one end is provided with angle bars 49 which are identical with the angle bars 39 and 4B and which function in the same way. When it is desired to apply and remove the belt l3, the angle bars are swung to an inoperative position and then the rollers are slid to the left, as shown in Figure 3. This will allow the rollers to be removed if desired and the belt applied or removed and then the rollers re mounted. may be formed by paint applied to the glass. Referring to the lower part of Figures 2, 3, and 4, it will be seen that the driving shaft 25 has a large gear 5! rigidly secured thereto. This gear is continuously in mesh with a small pin ion 59 rigidly secured to the shaft 25’. The gear 5| is provided with a number of pins 53 which extend at right angles to the surface of the gear wheel and which preferably are even ly distributed though they could be unevenly distributed. The parts are so proportioned and positioned that as the pins 53 rotate with gear wheel 5| they will successively engage and press downwardly the button 54. This button is an ordinary push button similar to a front door but ton now in common use, and acts to close the circuit to the buzzer or sound-producing device 3. Current from any supply line of 110 volts en~~ ters the device and some of the current is trans 60 formed by a transformer 56 so that the current supplied to the buzzer 3 will have the voltage greatly reduced. The current entering the de vice, however, is supplied at full voltage to the electric motor 55 and this motor is caused to sections may be anv integral part of the glass or 30 This leaves clear or translucent sections for the pictures l4 and 15. When the parts are in the position shown in Figure 4, the pictures l4 and 55 are in alignment with the transparent sec 35 tions 1 and 8 of plate 6 so that the pictures may be readily seen especially when the lamp 69 is functioning. This lamp is turned on when the slide 65 moves to the position shown in Figure 4, and is turned off when the slide moves to the left 40 as hereinafter described. It will therefore be seen that whenever the pictures are exposed to view, lamp 69 will function to provide the desired illumination. Slide 65 is provided with a pair of upstanding pins 10 and ‘H which form, in a certain sense, a bifurcated projection in which a pin 12 slides. This pin is rigidly secured to a lever 13, which lever is pivotally mounted at 14. The upper end of the lever, as shown in Figure 4, is provided 50 with an insulated contact 15 adapted to be moved into and out of engagement with an insulated contact 16. When these contacts are engaged lamp 69 will be supplied with current but when the parts are moved to the dotted position in 55 Figure 4 the lamp 69 will be deprived of current. A pin l‘! is connected with lever 13 and extends into the cam groove 18 of a cam 19. This cam groove is provided with two dwells 89 and two shifts 8!. The cam 19 is rigidly secured to the shaft 25 and rotates therewith. When the pin 1'! is passing through either of the dwells 89 the slide 55 is stationary. The parts are so po sitioned that the pin Tl will be passing through function at a certain speed whereby the power shaft 56 will be rotated as long as the motor 55 is supplied with current. A worm 5'! is rigidly secured to the shaft 56 and continuously meshes with a worm wheel 58. These two members are a dwell when the parts are in the position shown in Figure 4 and will also be passing through a dwell when the parts are moved to the dotted position shown in Figure 4. It will therefore be preferably arranged in a housing 59 which is quickly to one extreme position and will stay in 70 that extreme position for a short time and will supplied with oil or grease so that these parts will function in the lubricant. A shaft 69 ex tends through the housing 59 and is rigidly se cured to the worm wheel 58 so as to be rotated thereby. From Figure 3 it will be noted that seen that the lever 13 will be swung rather then quickly swing to the opposite extreme posi— tion and remain in that opposite extreme position for an appreciable time. This action is con tinued as long as the device is functioning. 75 2,120,809 Referring more particularly to the belt I3, it is to be understood that the same may be made from silk, cellulose matter, or other material without departing from the spirit of the inven tion. However, this belt is preferably substan tially transparent and is formed of two strips of material l3’ and I3" with lines 52 for indi cating spaces in which the slides 52' are adapted to be placed when in use. The slides 52' are 10 preferably made of the same kind of material as belt I3 and are adapted to receive the legend plates 52” before the slides are inserted into the belt. The strips l3’ and I3" are secured together along one longitudinal edge by a ?exible binding member l3'”. Usually the plates 52” carry letters or numerals but they could carry other legends and even pictures without depart ing from the spirit of the invention. Also these plates may be made from the same material as the belt or from some other material and be either opaque or translucent. However, these plates are preferably made from transparent ma terial which is somewhat resilient so that they will readily pass around the various rollers dur 25 ing the functioning of the device. There is pro vided a continuous illuminated lamp 82 substan tially centrally within the travel of the belt l3 so that the letters or other con?gurations car ried by the plate will be illuminated and they 30 will readily be seen during the day or night. Preferably a number of the plates 52” are mount ed in a carrier or slide of transparent material and this carrier inserted between the two strips l3’ and I3". In Figure 8 will be seen a diagram showing the various wires used in the device. The wires 33 and 84 are lead-in or supply wires which will be of the usual voltage used in the particu lar locality where the device is mounted. Usu 40 ally the supply of voltage is 110 and, conse quently, the lamps 69 and 82 are made to re ceive this current. The clock l6 and lamp I‘! are also made‘to receive this current as well as the motor 55. However, the buzzer 3 is pro vided with the transformer 56 so that the current used in this device will be greatly reduced, as, for instance, reduced to six volts. The wires and 86 supply current at full voltage to the transformer 56, while the wires 81 and 88 fur nish current at reduced voltage to the buzzer 3. The wires 89 and 9!] supply current to the clock i5 and lamp ll, while wires 9| and 92 supply current to lamp 69 whenever the switch formed by contacts 15 and 16 is closed. The constantly burning lamp 82 is connected with wires 83 and fill and has a hand-operated switch 93 to open and close this circuit, while the motor 55 is sup plied with a switch 94'- to connect and discon nect the motor with the supply wires 83 and 84. When the device is functioning it will be seen that the parts of the device using the current will be continuously supplied with current except lamp 6.‘! which is intermittently supplied 65 with current as the lever '13 swings back and forth.
