Application filed March 3, 1921. `Serial No. 449,537.

To all whom t may concern Be 1t 'known that we,WALTEn I. MAYER and Frnnnrcn Braamt, citizens of the United county of Jackson and State of Missouri, have invented certain new and useful Improveniente in Display Devices; and wev do declare the following to be a full, clearLand exact description of the invention, such as will enable others slrilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to a display or advertising device and particularly to a device which maybe conveniently located in a display window upon a counter orl upon a table, the device" beingso constructed thatit willfmechanically bring into view different objects preferably at uniformly divided stages or periods and when the end of the sequence of operations has been reached, the device is so constructed that the displayedobjects will bere-displayed in reverse order. `For example,V the devices to be`- displayed or (the matterto be displayed, as" the case may be, may be arranged on leaves or panels whichA `may be moved one after the other intermittently in one di rection, for example,` from right to left,

until all"` of the leaves of panels have been operated; then the last leafY or panell will bethefirst one moved from"V left to right in This alternating relatioii of? movement will continue so long aslfpower is applied tothe mechanism fer operating the leaves or panels.

'llhe novelwconstructioliofthe iriveftion as` well "as the means of operation, will" beu come" apparent by referenceto the following descriptionin connection` with the accompanying drawings, in which- `Figure 1 1s a Aperspective viewfof a dis` play device constructed" inl accordance with our invention.

Fig, 3 is ai vertical, longitudinal, sectional view through the deviceb sig; i aan @age elevational. View of the operating i i motor 8, on the drive shaft 'with ai gear 20 on to the drawings by numerof a case having a 3 and d and a re- On the base 1 is a gearing supporting frame consisting of the two plates 6 and 7, fastened to the base 1 and provided with bearings for certain of the shafts which support the transmission gears.` The base also carries an electroof which is a pulley 9 driving a pulley 10 on the shaft 11 through the medium ofthe belt 12. The shaft l11 is mounted in bearings in the respeetivefplates 6 and 7 and said shaft `carries a pinion 13, which meshes with a gear 1li: on the shaft 15, mounted in the plates 6l andf?. The shaft 15 carries a pinion 16, which meshes with a gear 17 on the shaft 18, also supported by the'plates 6 and 7 and on the shaft 18 isa pinion 19 which meshes shaft 21' carried plates Gland 7. rlhe shaft 21 has y shaped coupling 22, providedgwith a'slot 23 therein to be engaged by'apin or transverse proje`ction2t` on a disk-operating shaft25 in a bea-ring armV 26, carried by the plate 6.

The gearing just described affords considerable reduction in speed between the iii-"rite1**sha-ft` and the dist: 27 rigid on the' shaft-25; therefore, the motor' atr4 relatively highspeed 4while head 2'? willl rotate atrelatively' low speed. The` 'disl'v27 is the leaffturner actuator' and it? perates with the leaf turning mechanism infrontof the casing,

The leaf turning mechanism is shown as;

are loose on the shaft 28 and their toothed portions 3d# mesh with the toothed portions 3 5 of, complementary disks 36, 37, 38 and 39 for thedisks 30, 31, 32 and 33 respectively.

"Each `dislr or mutilated gear 1s providedwith an` outstanding, arm? or finger 40, alims am er laterally projecting to be engaged by anactufinger 4:1` on the leaf" by the a capmay operate; the disk Vorf v nated. 51.

actuator or disk 27. The number of fingers or arms 41 on member 27 will correspond to the number of arms 40 to be actuated and the arms 41 will be of progressively increasing lengths so that the first arm for the finger 40 on the disk 33 will be long enough to contact with the finger on disk 33 but will be too short to contact with the finger on disk 32. The next arm 41 will be long enough to contact with the finger 40 on disk 32 but not long enough to contact with the finger lon disk 31, the next arm 41 being long enough to contact with the finger 40 on disk 30. Therefore, as the disk or head 27 rotates, the fingers 41 will progressively engage the fingers. 40 on the respective disks or mutilated gears to turn the disks 39, 38, 37 and 36 in sequence.

The disks 36, 37, 38 and 39 carry fingers 42, 43,44 and respectively, having grooved portions to support the panels or leaves 46, 47, 48 and 49. Therefore, as each mutilated gear ordisk carrying an arm 4() is turned, a corresponding movement will be imparted to its-.complementary leaf-carrying disk so thatV the leaves will be folded over from Y right to left until all of the leaves have been turned.

Vhen all'of the leaves have been turned, the last arm or finger 41 will have passed the lingers 40 and the arms 41 willlbe car- V.ried to the lower portion of the casing to engage corresponding fingers 40 on a set of `mutilated gears, generically designated 50,

which lengage complementary leaf-turning disks, the `group being generically `desigcorrespond indetail to vthe groups at the top, as the arms 41 contact with those designated 40 at lthe bottom, the reverse order of movement ofthe leaves will take place, as

p, will bewell understood, the leaves being progressively turned until all of them have been restored to their original position, after which the arm or finger 41 will have moved to the top to again turn them from right to left.Y The alternating sequences will be continued lso long as the device is operated.

The motor may receive power from any suitable source as, for example, a commercial circuit, and I have shown a plug 52 carrying conductors 53 and 54. The conductor 53 Vis connected to a switch 55, whereby the circuit maybe broken. The conductor 53 is also connected to lamps 56. and 57, the conductor `54 being interrupted by insulated contacts 58, adapted to be bridged by the spaced conductor plates 59 in the back of the disk or head 27, as will be clearly seen in Fig. 2. Therefore, as the disk rotates, the light circuit will be intermittently closed I, f, and opened to flash the lights intermittently,

the contacts being arranged so that the light will be flashed on when the leaf has been turned and flashed ofi' while the leaf is turnince the groups at the bottom ing. The motor is connected to the circuit consisting of the conductors 53 and 54 in parallel, as shown in Fig. 2, and there is preferably a rheostat 60 for controlling the speed of the motor.

The circuit wiring is not important as any means can be utilized for flashing on the light at such times and at such periods as desirable, the essential novelty of the invention residing rather in the mechanism for operating the panels of leaves.

The mutilated disks or gears on the respective shafts 28 and 29 may be mounted in any convenient manner and are preferably spaced apart by spacing washers or collars 61 and 62.

It is apparent, of course, that the removable panel 5 in the back of the machine may be secured in any convenient manner and it is adapted to be taken out in order that access to the interior of the case may be had whereby inspection or repairs to the mechanism may be made.

Attention is called to the fact that the arms 40 for the leaf-turning elements at the bottom of the shaft 29 are offset with respect to the arms 40 at the top, this being desirable because when the leaves have been turned over in one direction, it is necessary to have the arms for the lower leaf-turning elements in line with the pins 41 when they reach the bottom of the casing so that they may come in contact with the arms 41 to turn the leaves back to their original position.

It is necessary to offset the arms 40 for the lowerleaf-turning elements with respect to the arms 40 because in the initial operati'on ofthe machine when a pin on the turned head contacts with the arm 40, it will impart a partial rotation to one of the upper disks and correspondingly turn the leafsupporting element, in turn giving a partial rotation to one of the leaf-turning elements at the bottom of the casing and since the leaf-turning elements at the bottom of the casing are in mesh with the mutilated gears of the set 51, there will be a corresponding turning movement imparted to that set of mutilated gears. Tf the arms 40 are not offset with respect to the arms 40, they would be moved out of the path of the fingers 41. By offsetting the arms 40 and 40' with respect to each other, there will always be one set of arms in the path of movement of the fingers.' v
