4 Claims.

This invention relates to improvements in display actuating mechanisms and refers specifically to a mechanism for simultaneously actuating or animating an advertising display by imparting thereto a plurality of motions of different characters.

The utility, objects and advantages of my invention will be apparent from the accompanying drawings and following detail description.

In the drawings, Fig. l is a side elevational view, illustrating the actuating'mechanism com-' prising my invention, driving a display shown diagrammatically.

Fig. 2 is a top plan view of the actuating mechanism.

Fig. 3 is a top plan sectional view showing the gear trains associated with the mechanism.

Fig. 4 is a sectional view taken on line 5--il of Fig. 3.

Referring in detail to the drawings, 6 indicates a casing which may comprise two substantially symmetrical metal shells 2 and 3. Each shell may be provided with an outwardly extending peripheral flange ii, said flanges being provided with a plurality of registering apertures 5 through which bolts 6 may pass serving to secure the shells 2 and 3 together. The casing i may be supported upon legs or standards 1, which may comprise metal bands bent in rectangular fashion in order to form three supporting the ends of the bands being secured to the lower shell 3 by means of bolts 8. Each of the sides of the bands l may be provided with apertures s whereby said bands may be bolted or otherwise fastened to a suitable support. The legs l being rectangular in shape provide means whereby the casing i may be positioned horizontally as shown in Fig. 4, or said casing may be disposed upon either of its longitudinal edges.

An electric motor it may be positioned beneath the casing l and between the supports 7. A pair of rods (not shown) may be secured in spaced relationship to the lower shell 3, said rods be ing. threaded at their upper ends and engaged with nuts II within casing I. The rods may depend from shell 3 upon each side of motor it and may pass through the field pieces 12 of said motor. Nuts It may be positioned upon said rods immediately beneath shell 3 and may serve to hold said rods in rigid position with respect to said shell. said rods and may serve to properly space the field pieces [2 from the lower face of the shell 3.

Cross members It and Il may be secured to said rods at the lower and upper ends thereof,

Sleeves I l and i5 may circumscribe said cross members intermediate their length, carrying bearings (not shown) which serve as journals for the armature shaft it of motor it. An arm 26 may be positioned upon each of said rods and may be confined upon said rods between the lower spacer I5 and cross member I6. Each of the arms 2t at their opposite ends may support brush holders 2i, brushes 22 for the motor being positioned within said holders and being adapted to make contact with commutator 23. A fan may be disposed at'the lowermost end of shaft l9 and may serve to provide an air circulation for the cooling of said motor.

Shaft It at its upper extremity may project through the wall of shell 3 and may carry at its upper end pinion 25. Pinion 25 meshes with gear 25 carried upon shaft 2i, the ends of which latter may be journalled in bearings 23 and 2d at its lower and upper end respectively, said bearings being secured by pressing in the walls of shells 3 and 2. A pinion 353 may also be positioned upon shaft 2? and is adapted to mesh with gear 3i mounted upon shaft 32, the upper and lower ends of which are respectively journalled in

bearings

33 and 34, which, similar to bearings 28 and 29, are positioned in the walls of shells 2 and 3. A pinion 35 is also carried by shaft 32 and is adapted to mesh with gear 36 mounted upon shaft (ll which maybe journalled inthe upper and lower shells 2 and ii. Shaft 3'! upon which gear 35 is mounted, projects above the surface of shell 2, and, as will be hereinafter more fully described, may be utilized to drive in a continuous manner a desired display.

A segmental plate 3% may be rigidly mounted upon shaft 3? and an arm 39 may be formed integral with said plate, said arm being offset below the plane of the segmental portion it of the plate. A rotatable pin 4! may be disposed at the end of arm 39 and upon rotation of shaft 3'! said pin is adapted to engage in slots provided in the periphery of Geneva gear is. Gear 53 may be mounted upon shaft 44 which may be journalled in bearings 35 and 46 respectively mounted in the shells 3 and 2.

A sleeve ll may be positioned upon shaft 44 and may be adapted to hold gear 43 in desired position within the casing I, that is, in the plane of the segmental portion 40 of plate 38. Slots i2 may extend radially in gear :33 and may be circumferentially spaced from each other. The periphery of gear 43 intermediate each pair of slots is cut away in an arc-shaped manner as indicated at 38 in Fig. 3, the radius of curvature of the are being similar to the radius of curvature of the segmental portion 4!] of plate 33.

Motor ill may be energized by connecting plug 49 to a suitable source of electric current and upon rotation of said motor, shaft 3"! is rotated. By means of the gear

train comprising pinions

25, 36, and 35, and gears 26, El, and 3B, shaft 3'! will be rotated at a very low speed. However, the rotation of shaft 3? is continuous during the period in which motor it is energized. When shaft 31 rotates arm 39 is revolved and the radius of said arm, that is, the distance between the center-line of shait 3'5 and the center-line of pin 4!, is such with respect to the radius of the Geneva gear #53 and the circumferential spacing of slots 42 from each other, that upon one complete rotation of shaft 3'? taking place, gear 43 will be moved a circumferential distance equal to the distance between adjacent slots 42. remaining cycle of rotation of shaft 3?, the segmental portion ill of plate 38 engages the cut away portions lS'of gear 33, but no motion is imparted to said latter gear. It can readily be seen that while shaft 3? rotates continuously, shaft :34 will move intermittently, the number of individual movements necessary to complete one revolution of shaft 3-4 depending upon the n i-- ber of slots 52 provided in the periphery of gear 43.

A plate 59 may be removably mounted upon the upper end of shaft M and may secured to said shaft by means of set-screw 5i. t is to be understood, however, that plate 56 may be dispensed with and a gear, pulley or crank arm (not shown) may be mounted upon shaft (i l.

In the intended use of my invention, two associated movable advertising display elements may be actuated simultaneously; For example, a hexagonal prismatic display device 52 having six display faces 53, may be mounted upon plate 5d and secured thereon by means of screws 54 or the like. A sheave wheel 55 may be mounted upon the projecting end of shaft Sland a belt or cord 56 may connect sheave wheel to sheave wheel 5'! which, in turn, may be mounted upon the connecting shaft the opposite end of said shaft carryinga sheave wheel 59. Wheel 59 may be operatively connected to sheave wheel 6:! by means of belt or cord 5i. Wheel Gil may be mounted upon shaft 62 which, in turn, may carry one or more cylinders 53 whose lateral sides may be utilized as dispiay surfaces' .7

It can readily be seen that by' this 'arran a ment prism will be rotated intermittently whereby faces 53 will be sequentially presented as viewed from one side of the display. Simultaneously cylinders 63 will be continuously ro-. tated and may also be viewed from the samepoint of View. This arrangement of an animated or mechanical display has been found to be very flexible and susceptible to being used in many attractive combinations. For instance, cylinder 63 may present or display a message which may be explanatory of a sequence of events which During the 7 and is presented merely for purposes of illustration. 7
