Renewed January 22, 1940 j 12 Claims.

This invention relates todis pl'ay signs and particularly to an improved automatically actuated mechanism for successively. bringingto view different signs, an object being to provide sults without requiring the attention of an attendant. v e

A further object of the invention is to provide a mechanism for bringing to view successive sign m sheets through a means which moves theZ-sheets to view in opposite directions and "which continually functions automatically'as long as the power is turned on.

An additional object of the invention is tov provide an automatic display machine, for-bringing the sign sheets to view in succession, wherein means are so formed that the driving meansop erates continuously and yet there'is-a'dwell after each sign has been moved to a display position. Another object is to provide a construction wherein the sign sheets may be readilybrought to view without danger of tearing ithef sheetsso that as the machine operates the same may repeat and present the sign sheetsfin good condlview different sign sheets in succession? and to.

providea balanced structure for the'mechanism whereby there will be no appreciable-momentum' of the sheets as the device functions;

' Referring to the accompanying drawings by numerals, [indicates a casing provided with a window opening 2 which is preferably closed by a transparent member 3'which is usually of glass. The casing i may be madeof wood, metal, or 729 other materiaL-and arranged so that the front, rear, top, bottom and sides are firmly held together, the front and rear being'removably secured in place. The casing is adapted to be supported on a wall orother support at any desired point so that the successive sheets 4 and 5 may be brought to view for displaying the matter thereon. These sign sheets are" adapted to be moved inopposite directions and simultaneously so that when the signsheet 4 movesupwardly it gradually disappears and the sign sheet 5 gradually appears. On the next-motion of the sign sheets a new sheet will move downwardly and take the'place of sheet 4 while'the old sheet 5 will move downwardly and out of sight. As the 5 front and rear'are removable the signs may be removed or changed either from the front or rear as desired. r a I In providing a mechanism to accomplish these results and to present a structure which will function auton'latically. and continuously for eitherlongor short periods of'time, improved 1fnechanism has been provided as illustrated particularly in Figs.'2 to 11 inclusive.

from'electricmotors but, if desired, it could be 5 operated by power from other sources. As shown in Fig. 3, there are'providedelectric motors 6 and I which are connected to a suitable source of current which may be turned on andoff manually as desired. These motors are arranged in positionto operate in opposite directions as indicated by thearrows in Fig. 2. The rotor of motor 6 is connectedto a shaft 8 whilethe rotor of motor 1 is, connected to a shaft 9. These two shafts are connected to a suitable reducing gear l adapted to rotate a pinion II in one direction when one motor is functioning and in the opposite direction when the other motor is functioning. It will be understood that the motors function at difierent times. The reducing gear may be of any desired kind but may be such that when the motor 1 is functioning to drive the parts the rotor of motor 6 will be rotated idly in a reverse direction, and when the motor 6 is functioning the reverse ac tion takes place.

respective chains l and I1. Each of these chains is provided with a lowering hook'or abutment l3 and a raising hook'or abutment ,l 9. The parts are so apportioned that the hooks ill will move intermittently to a position slightly below the lower edge of opening 2 and then the hooks IS will move upwardly to a position slightly above the upper edge of opening 2. This back-andforth motion of these hooks and of the chains which carry the same continues as long as the device is operating. The hooks it, as heretofore fully described, will act on one of the upper sign sheets to move the same downwardly, while the hooks I9 will operate on one of the lower sign sheets to move the same upwardly.

As illustrated'in Fig. i, there is provided a construction which may bev termed a spool 26 at theupper part of the casing I and a second spool 2| at the lower part of the casing- These spools are identical but operate in opposite directions. It is therefore thought that a description of one will be sufficient to serve them-both. For instance, spool is provided with spool ends or disks 22 and 23. Each of these disks is provided with radiating apertures 24. As illustrated in the drawings, there have been provided. twelve of these radiating apertures or slots but itis evident that a greater number or even a less number might be used without departing from'the" spirit of the invention. On one of the disks 2?. there are provided a number of roller-carrying bars 25 and on the other a number of rollercarrying bars 25. These bars are constructed as shown in Figs. 8 and 9.. Bar 25 is provided with apertures 27 for receiving, ball-retaining members 29 and 3!], as shown in Fig. 6, and a third aperture 3| for receiving the small end of a rod 32. The opposite end of rod 32 is provided with squared portions 33 which fit into a notch 34 in the bar Bar 26 is provided with apertures 35 for] 26. receiving spring-pressed balls, as shown in Fig. v6. It will be noted that the disk 22 is provided with an auxiliary disk 35 which may be welded or otherwise secured in place and which is provided with sockets for accommodating the respective springs 31 and 38 which hold the balls 30 in functioning position. It will be understood that I there is provided a pin 32 for each of the notches or slots 24 and each pin is connected with what may be termed a sign roller 39. This rolleris provided with'a coil spring 40 so that the roller, I

As illustrated in Fig. 11 and as hereinafter fully described, means is provided This shaft spring and associated parts will have a tendency to rotate: in one direction, the structure being substantially the same as an ordinary shade rollerwithout the locking pawl. A sign sheet is secured to and wound on each of the'rollers 3Q.

Each of these sign sheets carries a rod 4! at the outer free end. ,This rod normally rests in the notch 42 of bar 25 at one end of the spool and rests in a notch 42' at the other end of the spool. As illustrated in Figs. 4 and 6, each of the sign sheets is provided'with a pair of cutouts 48 for receiving certain actuating members herein fully described and which engage the rod ll inthese cutouts so as to raise or lower the sign sheets as the device functions.

As illustrated in Fig. 2, there is a sign sheet for each-roller 39 and there is provided a roller for each of the slots 34. The rods 41. rest in the notches 42 and 42' of the respective bars 25 and 26 ofthespool 25 until positively moved therefrom by raising and lowering members M. 7 shown in the drawings there have, been provided two members 44 but agreater number may be used without departing from the spirit of the invention; These members are rigidly secured to the slide bar 45 bywelding or other means. Each of these members is provided with an upper hook .46 and ajlower hook 4'! for engaging the respectiverods 4| as hereinafter fully described. The slide bar 45 has an upstanding plate or bar 48 adjacent each end and these plates carry a bar 65 which is parallel to the bar 55. The bar 45 is provided with a number of apertures which may be rectangular or some other shape and whichcoact with apertures 55 in a slide bar 52 slidingly mounted in bar 45. The slide bar 52 has anextension at one end which carries a I friction roller 53, which. roller rollsover the undulating surface 54 of the casing I. A contactual spring 55' (Fig. 4) is connected to the extending end 56. of the slide bar 52 and at 51 to the bar 45 soas to give the slide 52 a tendency to move to the right as shown in Fig. i. As the bar moves upwardly and downwardly the friction roller 53 will cause the slide 52 to move back and forth in conjunctionwith theraction of the spring 55. V

' As there are provided a number of electric lamps 58 (Fig. 2) in the casing I and in front of the reflector 59, light will be projected through the openings 50 and 5| but a blinking action will be produced. This is designed to call attention to the sign as moving lights usually secure this result. This blinking action will take place as the bar 48 moves upwardly and downwardly. It will be noted from Figs. 2 and 3 that the plates or bars 48 are each provided with an aperture and through these apertures the respective guide bars or standards 60 and BI slide. Tubular extensions or sleeves 62 and 63 extend upwardly and downwardly on the respective bars 48 so that the bar or frame 45 may easily slide upwardly and downwardly during the functioning of the device. It will be noted that the bars or plates 48 are each provided with an extension .64 adapt-- ed to be engaged by the respective hooks I 8 and PAS - described the bar 4: carried by the hook 46 .will

closed current is switched off. from one of I the motors and on to the other so that'the'mechanism will immediately begin to'function to move the hook l8 downwardly, while'thereverse is true in regard tothe actuation-"of switch 68, namely, when switch 68 functions hook-l9 willbegin to move upwardly and continue to move upwardly until the extension 69 actuates switch 10;" These switches are only momentarily closed when the circuits of the respective motors are closed for the desired length of time to secure. the proper movement of the parts to causethe various hooks to function asjust described. 3

In order'to balance the chains and associated parts there is provided a weight 1! and a suitable guide 12 on each side of the device. Cables 13 extend upwardly from these weights and have sheet, as for instance sheet 4, downwardlyfas shown in Figs. 1 and 5, the respective hooks 46 extension 65 ofbar 48 will-strike theend of lever will be in engagement with the rod 4| of one of the sign sheets carried. by the spool 20 .while the hook 41 will be engaging the=rod .4I carried by the spool 2 l As illustrated in Fig. 5,- the frame 1 or bar 45'is moved downwardly under the action of hook I8. Theparts will then'move fromthe poi I be a similar dwell or stationary period for the low-' sition shown in .Fig. 5 to that 'shown'in Fig. 7 wherein the rod 4| carried by hook 41 will come to rest in the'notch 42 of ,one of the bars 26.

This bar at this time is'stationary and, conse- J quently, as the member '44 'continues topmove. downwardly hook 41 will move below the bar .26' which has just: received the;rod 4|; -As the parts continue to move downwardly the upper :sign sheet 4 will continue to move downwardly and the Wardly to the dotted positiontshowninFig; 5.

- This lever .is journaled on thershaft'2l'1ofspool 20 and as the lever is moved downwardly .the rear extension 18 will move up'wardly. A pawl 19 is pivotally mounted arse .to'theextension 18. This pawl will engage'in' one of the teeth-M of a ratchet wheel 82 and move the shaft 2 i the spool end 22 and associated 'parts.-as well-asthe spool end 23. It'will be understood that the respective spoolends are pinned or'otherwisesecured to shaft 2! so that both ends will move-at the same time and in the same direction.- A flat been left in the socket42 as shown in Fig. 7,

will move downwardly so that upon the return movement of hook 41 saidhook cannot again engage this particular rod but will engage rod 4! of the next sign sheet, and as the hook and associated parts move upwardlythenext sign sheet will' be brought to view oppositetheopening 2. 'As the next sign sheet is being movedupwardly asjust substitute new ones, i I p Referring'more particularlyto Fig. 11;'it will be movedupwardly under the action of the spring "on'the pawl'carryi'n'g this particular sign "sheet. :It willbe seen,'therefore, that by reason of the coil springs ifl whenever a sign sheet isreleas'ed by 5 'an upward ordownward movement of member 44, the-coil spring .40 associated therewithwill -rewind the sign sheet so'that it will be ready for the next unwinding. *As thehooks i8 and I9 move downwardly a sign sheetfroin the upper 10 spool will be moveddownwardly' and "then a sign sheet from the lower spool will be moved upwardly and the first sign sheet will be rewound and the upper spool turned one notch'so as to bring the second upper sign sheetinto place. This action. 15 is continued until alltwelveof the upper and all twelve of the lower sign sheets have been brought to view; If there should be more than twelve 'sign sheets they will allbe brought to view before the sign sheetswillrepeat. j 20 As illustrated in Fig; 2 when the hook l8moves downwardly tothe lowerend of the opening 2 the frame or bar will remain in its lower pos'ition while theihooks l8 and i9 will move. Hook bar 45 upwardly and all the partsassociated therewith.- During the time the hook i9 is in atz30 certain sense catching upwith the frame or bar 45, there is adwell or stationaryperiod for the upper sign sheet, When the hook 19 moves to itse1 sign sheet Which is exposed throughthe'opening 2. As there are no' complicated parts present the mechanism'will continue to function conftinuously forthe period of' timeidesire'd but it =wi1l beevident thatfthe exposure of. the respec-cmq tive. sign sheets on the respective spools'of the mechanism will repeat the exposures. This -rep-.

' etition is continued as. long as the: machine funcjtions.

At any time an operator may turn off the'current and remove the old sign sheets andiil be seenthat-there are provided apa irof'supply Q lead-in wires 84 and 85, the lead-inwire 85 being divided and connected with one endo'f the re spective magnets 86 and 81. The endila of magne't81 is connectedthrou'gh wire 89 to contact member 99 of switch 10 while the end 9lof magnet 85 is connected. through wire92 to contact member'93. 'I'he're'spective contact ni'embersi lis 94 and95 of the respective switches are connected bywires 96 and 91 'to the lead-in wire 84. This lead-in wire-is connected by wire98 to one side of the respective members 6 and 1 and at the other side throughwires 99 and [00. to the' BO contacts IOI andlilZ, Anarmature lfl3is connected at I04 to wire 85 and is pivotally mounted so that when magnet'Bfi is energized itwill engage contact II, but whenmagnet 81 is energizedit will engage contact I92. By reason of this constructionwhen the switch 68 is closed temporarilymagnet 98 will be magnetized temporarily and'will swing armature I03 to the position shown in Fig. 11 where it remains until the switch 10 is temporarily closed. The temporary closing of switch 10 will temporarily energize magnet 81 intothe circuit'mot'or 1;This will cause a rat-= "versal :of themovementipf theipinion II handas- 'sociatedr partssas heretotore'a. described.

:.As a: modified construction to that; shown in :spool: ends may be provided with'hook extensions 11105 whichvwill idol away with the construction shownnini Figs: Band 9. However, therexis prov vidcdasp'ring me forveach "of :the rollers139 so H ashto receive-the squared end as shown in .Fig. 13. This rectangular orcsquared end fits winto a rectangular or -squared opening 1 08 in the spring so' as to: prevent :the" rotation of the rod 32.

Onewend-of. the spring" 48 is connected with this z rodz and the other end withthe roller 30 so that "when the respectivespins M are released the signsheets Willquicklybe wound on their respeca'tiverollers, as shown in Fig.: 10, but may be readilyipulledtherefrom by ;the actuating member 44.
