General arrangement In general, the changeable exhibiting or displayv device of the inventioncons-ists of a housing having a pair of endless conveyors with hooks thereon adapted topick up and convey the projecting. ends of exhibited obj ects, such as posters, pictures, signs, orthe like. 'When thus picked up at the display position, the postersor signs areconveyed over suitable guide rollers to a storage position at the back of the housing, 7

Before the posters or signs "reach the storage position, however, they are permitted to drop a short distance, preferably by gravity,'so that they fall out of engagement with the conveyor hooks. Uponbeing thus released from the conveyors, the poster, sign, orthe like, is intercepted by suitable mechanism anddirected into an inclined guide along which it moves towardthe display position. When the exhibited object, such as a poster, V nears-the end of the inclinedguide, it is engaged .by a feeder which feeds it into the path of the Here it remains forthe display period and in the display position until the conveyor hooks arrive opposite the projections at .the endsof the poster. When this occurs, the poster or sign is again conveyed by the conveyor from the display position to the storage position and the foregoing cycle is repeated.

Each exhibited o iect is inthe form of a sheet or panel and is provided with pictures, signs or .thelike, on its opposite sides, one being inverted relatively to the .other. Thus in the changeable exhibiting of this invention, the device will display twice as many signs or pictures as there are sheets or panels in the device.

The opposite ends of the panels or sheets are provided with transverse rods, the ends of which project so as to provide engagement between at a time, namely, the object which has reached the display position. This arrangement prevents the jamming or chafing of the various panels or sheets, thereby protecting their surfaces as well as preventing a breakdown of the device. The signs or posters, while in the display position, are tilted relatively to'the vertical so as to be clearly visible. to persons viewing them from beneath,as well as to provideconvenient means for illuminating the posters or signs by sources of illumination placed in the bottom part of the housing. The housing itself may thus be made very compact because the storage space is immediately behind the display position and each poster or sign is moved over the top of the mechanism from one position to the other.

Driving and conveying mechanism Referring to the drawings in details, Figs. l to 3 show the driving and conveying mechanism and the supporting structuretherefor. -The device is supported upon a base l9 h-aving a back H, a removable top l2,,front l3,and sides It .being shown by chain lines, In Figs. 1, 2 and 3,

these are'removed for the purpose of more clear ly showing the mechanism normally enclosed therein. The front I3 is provided with inwardly directed portions I5 and it leading to a display aperture l'i through which the exhibited objects, such as posters or signs, are viewed'by persons in front of the machine. The portion i5 is preferably removed in the event the device is illuminated byartificial light, and electric lights are placed in thelower part of the housing, together with suitable reflectors. V

The changeable exhibiting device of the invention is supportedby a framework consisting of lower side plates I8 mounted on the base l0 and interconnected by horizontal angle members i9, the latter being secured to the former as at 2e. Secured to and rising from the side plates l8 are the oppositely facing front and rear angle uprights 25 and 22, respectively. Midway of their heights the uprightsv 2i and 22 are interconnected by the bent strips 23 (Figs. 2 and 6) which in turn carry the supports 24 to which are secured the upright guides 25 for the ends of the posters or signs being exhibited. The upper ends of the uprights 2i and 22 are secured to and interconnected by the upper side plates 2'5 (Figs. 2 and 3) which serve to support the feeding, guiding and conveying mechanism as described below. The upper side platesv 26 are interconnected by the horizontal angle members 27 secured thereto as at 28.

Mounted on the base It (Fig. 1) is a driving motor 243 having a shaft 31 carrying a pulley 32. The pulley 32 drives a pulley 33 upon the input shaft 34 of a reduction gear box 35 by means of a belt 36. The reduction gear box 35 preferably contains a worm 35 driving a worm gear 3'! mounted upon a sprocket shaft 38 which is rotatably supported at its opposite ends in the lower side plates la. The mechanism at the opposite ends of the machine is substantially duplicated and bears corresponding reference numerals, hence it will be suflicient to describe and illustrate one end only of the machine shown in Figs. 4 to 10. Mounted on the sprocket shaft 38 and secured thereto are lower sprockets 39 (Figs. 1 and 7) The-sprocket shafts also pass through the brackets 49 which are secured at ii to the lower side plates i3 and support the lower ends of the upright guides 25. The sprockets 39 carry sprocket chains e2 which mesh with the upper sprockets named on the stub shatters tFigs.

Loosely mounted for free rotatiomupoi the inwardly racing ends of tn shafts 44 are discs ll constituting the opposite ends of a guideroller 48'. The latter is referably constructed of light weight material and serves to-slippert the posters or names they arecarried over the top of the mechanism from the display position to the storage position. The shaft M also passes through the uppereud of a plate-likernember ta w'nicn constitutes tneupper portion of the guides 25, the lower portion 50 being mounted" on" the bracket to iii the manner previously de scribed. i

Mounteacn triesproeket chains" 42 are the upper and lower conveyor hooks 5| and 52, res ectively (Figs. 5 and?) These conveyor hooks 51' arid 52 are spaced apart by approximatel the vertical dimension of the sign or poster being exhibited and their inner ends pass along paths extending longitudinally and vertically within the angle portion of the upright guides 25.- The posters, signsor the like; are provided-with trans verse rods 53, theendsof which project into the sheetsof the conveyorhooks 5|and 52 seats to be'e'ng'aged thereby; The exhibited object, generauy designated 54 (Fig. 9 ),-preferab1y consists of a heet securely clamped, in any suitable way", between the members 55 which encircle the rods 53.

Secured to the outer ends of the upper sprocket shafts M, asat 51; are pinning-5M a s n 10) which mesh 'withthe internal ring gears 5Q secured as at to the pains Bl? cam 6| is I mounted upon athreadedhub 62 by means of a nut es and is freely rotatable upon a fixed shaft 64 having a head SS by which it is mounted in the aperture 66 of the upper side plate 2 6. A

nut 67, threaded upon the shaft 64, serves'to retain the latter in position. The cainhub 62 is itself retained in position by the retaining bolt 53 threaded into the outer end of the 'fixed shaft 64. V U I Q Feeding, guiding and intercepting mechanism The mechanism for" feeding the various signs, posters or other exhibited objects, to the conveyors is operated in timed relationship with the cams 6!. To this end, the earns 61' are engaged by cam rollers Ill 'rotatably niounted upon pins ii on arms 1'2 (FigsB and 10); The latter are secured as at fliito the shafts 14 whichin turn are pivotallysupported in the bearings -15 and '55 inserted apertures 1'! and {iii in the membersfiii and zfljrespectively. Tubular, spacing ele cut it encircles the shaft M between the hearings l5 and '15.:

Secured, as at 80, to'the opposite end of the arm 1?. from the roller 12)," is a coilfslpring 8| (Fig. 8) which in turn is secured as at 82 to one of the uprights 21 (Fig. 2). This spring 8| constantly urges the roller It into engagement with tracted position;

the opposite end or which passes through the aperture 89 in the side plate 26 (Fig. 5) and Which-is secure'dthereto by the nut 90 threaded upon the outer-end thereof. The arm 83 and the corresponding arm of the bell crank 81 are of substantially equal length between their pivots are also substantially parallel so that the feeder 85 moves to and fro when the cam roller it? rises and falls under the influenceof the cam 65. The outer end of the feeder 85 is provided with a notch 9| into which the ends of the rods 53 are adapted to drop.

A lined detentSZ (Fig. 2) secured by the screws so to the upper side plate 26 serves to permit only one rocl 53 to drop into the notch 9! at a given time; A slot 94 in the fixed detent e2 permits the vertical adjustment of the latter.

The opposite end of the feeder 85 is bent upwaruly to form an intercepting portion 95 which moves into the path of the conveyor chain 42 toward the back H when the feeder 55 is in its retracted position. The intercepting portion 35. as hereinafter explained, serves to engage rod 53 which has passed over the top of the guide roller is and directs it upon an inclined guideway 96 (Figs. 2 and 5) seeuredto the member 49.

' The rods 53 move down this inclined guideway toward the fixed detent 92, under the influence of gravity, and the-foremost rodEiS drops into the notch 9| when the feeder 85 is in its re- The lower arm of the bell crank S! is provided with a'pivot pin 9'! "carrying' a downwardly directed separator rod, the

lower end of which is pointed as at 99. This rod 7 so is guided by the member let (Fig.2) secured. to the upright guide-25 (Fig. i). This separator rod serves to separate the foremost lower rod 53 from the remaining rods while they are suspended within the apparatus. tions the separator rod 98 is operated in timed relationship with t'he reciprocation of the feeder 85.

The lower part of the apparatus contains lower guides lEll, one on each side, and secured as at It?! to each lower side plate l8. These guides it! serve to guide the lower rods 530i the posters or signs 54 as the latter are conveyed upwardly by the conveyor hooks 5!; It will'be seen from Fig. 2 that when the posters or signs 54 are in either a display or a storage position, their planes are inclined to the vertical. Thus, the pull of gravity upon the lower rods 53 causes the foremost of these to be urged against the guides lfll while the upper rod 53 is being conveyed upwardly by the upper conveyor hook 5|. The distance between theloottorns of the curved portions of the conveyor hooks 5| and 52 is somewhat less than the length of each posteror sign to move forwardly (Fig. 3) out of the way of the conveyor hock 5:! as the conveyor hook 52 moves over the top. of the apparatus. The

slightly shorter separations of the conveyor hooks 5i and 52 than the length between the upper and lower rods 53, causes the poster to By these connecdrop under the force of gravity by an amount equal to the diiference between these two distances so that the lowermost rod 53, which has heretofore been below the curved portion of the conveyor hookv 52, now drops into this'curved portion while the upper rod 53, which has now become the lower rod, drops out of the corresponding curved portionof the conveyor hook and slides around the corner IE3 out of the way of the downwardly traveling conveyor hook 5|. Apair of lower rearward guides Hi5, secured as at H to the rearward uprights 22, serve to fend the lower rods 53 forwardly in the event that they should tend to start swinging, pendulum-like, as they move downwardly.

From Figs. 4 and '7, it Will be seen that the upper and lower sprockets 4,3 and 49 are of different diameters. In order to cause the conveyor chain hooks El and 52 to clear the rearmost lower rod 53 (Fig. 3), there are provided idler sprockets Ill! mounted on studs H38. The studs I98 are mounted in blocks Hi9 (Fig. '7) and secured thereto by the nuts ID threaded upon the outer ends thereof. The blocks It!) are slid- V able verticallyin slots in the lower side plates secured, as by the screw lll (Fig. '7-) The outer ended the rods 53 are rounded as at H3 so as to'permit them to engage the guide structure 25 with the leastfriction.

' Operation The operation of the device has already been explained, in part, in connection with the description of the construction thereof. The device is prepared for operation by placing a plurality of signs, posters or pictures 54, generally called the exhibited objects, upon the inclined guideways 98 with the upper rods 53 resting upon these guideways. The lower rods 53 hang suspended freely from the sheet portions with the foremost lower rod 53 in contact with the inclined lower guides IN. The conveyor chains are adjusted upon their sprockets and the cams 6| correspondingly adjusted so that the oscillation of the feeder will take place in proper timed relationship with the motion of the conveyor hooks 5| and 52.

' The machine is then started in operation by energizing the motor 30, rotating the conveyor sprocket shaft 38 and the conveyor sprockets 39. As the conveyor hooks 5| move upwardly, the large diameter portion of the cam 6| engages the cam roller 10 and swings the arm 12 downwardly, rotating the'shaft l4 and the arm 83 forwardly. This reciprocates the two feeders 85 ina forward direction and advances the foremost upper rod 53 of the foremost poster or sign 54 into the paths of the uppermostconveyor hooks 5|. The position of the parts at this portion of the cycle of operation is shown in Fig. 2.

The falling upper rods 53 are prevented from .moving forward by the fixed detent 92. The eX- hibited object 54, such as a sign, poster or picture, remains in this forward or display position while the cam roller 10 rides upon the large diameter portion of the cam 6| (Fig. 10).

Each adjusting screw H2 has a Meanwhile, the conveyor hooks 5| have moved upwardly to positions on the same level as the feeders 85 and pickup the ends of the upper foremost rod 53. As the conveyor hooks 51 move upwardly around the upper sprockets 43, they pull the foremost poster or sign 54 over the freely rotatable roller 48 and down .upon the rearward side of the machine. As the lower rod 53 of the foremost poster or signv 54 passes over the top of the roller 48, the weight of the sign or poster 54 and of the other rod 53 which has now become the lower rod, causes the poster to drop downwardly a short distance so that the leading rod 53 drops out of theconveyor hook 5| and moves around the corner E83 (Fig. 3), while the trailing rod 53 moves into the curved portion of the conveyor hook 52. The parts are now in the positions shown in Fig. 3. The leading rod 53 thus moves out of the paths of the conveyor hooks 5| and moves-downwardly.

Meanwhile, the cam 6| has been rotating so that the roller 16 arrives at the fiat spot thereon (Fig. 10) and, accordingly, swings the arms '52 and 83 (Figs. 3, 5 and 8) upwardly and rearwardly. This action reciprocates the feeder 85 rearwardly into the position shown in Fig. 3. The intercepting portions are thereby moved rearwardly into the paths of the ends of the trailing rod 53. When the conveyor books 52 arrive on the same level as the intercepting portions 95, the latter engage the ends of the rods 53 and remove them from the conveyor hooks 52. As the latter continue to move downwardly, the rod 53 is guided onto the inclined guideways 95 as shown in Fig. 3.

Inthe meantime, the bell cranks 8'! have been reciprocated so as to raise theseparator rods 98, thereby permitting another lower rod 53 to move forwardly into engagement with the guides llll. The rearward reciprocation of the feeders 85 also has brought the notches 9| thereof into the positions shown in Fig. 3,-back of the fixed detent 92. The ends of the foremost rod 53 may then drop into the notches 9| ready to be moved forward upon the next reciprocation of the feeder 85.
