PORTS, TROUTDALE, OREGON MOVING DISPLAY SIG-N Application led. December 11, 1928. Serial No. 325,289.

My present application relates to my United States patent application, Serial Number 52,118, filed August 24, 1925, upon a Moving display sign.

The object and purpose of my present application is a simplified form of construction, adapted for use in the displaying of a multiplicity of signs continuously appearlng 1n the same order withina relatively narrow display case, the case being adapted to d isplay a permanently fixed sign on either side and at the lower edge thereof, means being provided within the end Astructure to indicate in moving form a disappearing sign that disappears and reappears in timed 'relationshi further object of my present invention consists in a sign relatively cheap in manufacturing cost, one adapted for the advertising of a relatively large numberl of products,

and one that can be safely hung and maintained in an open passageway or over a sidewalk. Y

-Still further objects of my present invention consist in a device that may be operated over relatively long periods without attention or care.

A still further object of my invention consists in providing means wherebythe direct rays of lights will fall directly upon the movable sign boards during a part of their travel and expose them to view and during the rest of their travel will remain in shadow. y

And still further objects of my invention 85 consist in providing abase adapted to prevent the falling of one or more of the sign elements should the same become disconnected. y

With these and incidental objects in view,

4o the invention consists in certain novel features of construction and combination of parts, the essential elements of which are set forth in the appended claims, and a preferred form of embodiment of which is hereinafter shown with reference to the drawings which accompany and form a part of this specification In the drawings:

Fig. 1 is a side elevation of the assembled device.

Fig. 2 is an end view, taken on line 2 2 of Fig. 1, looking in the direction indicated.

Fig. 3 is a longitudinal, cross section view, taken online 8 3 of Fig. 4, looking in the direction indicated. y

Fig. 4 is a cross sectional front view taken on line 4 4 of Fig. 2, looking in the direction indicated.

Fig. 5 is a sectional, end view, taken on line 5 5 of Fig. 4, looking in the direction indicated.

Fig. 6 is another embodiment of the end view taken on line 2 2 of Fig. 1, looking in the direction indicated. y

Like reference characters refer to like parts throughout the several views.

I preferably form my display case of a rectangular housing, having paneledV side walls 1, and 2, the same being adapted for the placing thereupon of a relatively permanent sign on which the main products to be advertised are displayed at either side of the display case. A top wall 3, connects the sides and ends. lThe ends are shownvat 4 and 5. The end structures have supportingVV bases for the brackets and journals' to be secured thereto upon which the sign structure is mounted. v i

Oppositely disposed brackets 6 and 7 are mounted within the case within which journal shafts 8 and9 are mounted. The journal shafts are preferably made in the forni of stub shafts to which are mounted toothed sprocket wheels 10. Disposed in the lower part of the case or acket is a transverse shaft 11, j ournaled within suitable journals 12 and 13. Also secured to the shaft 11 are toothed sprockets 13. The shaft 11 is the driving shaft and the sprockets 13 are iXedly secured thereto. Endless chains 14 and 15 are trained about the sprockets and are driven f in timed relationship with each other. A prime mover, as an electric motor 16, is mounted within the case and has a worm reduction gear 17, secured to the main driving Y shaft which is adapted to coact with the worm wheel V18, also xedly secured Lto the shaft 11. This imparts rotation to the shaft 11 and to the sprockets 13, mounted thereupon, and likewise to the endless driver ele- V100` ments 14 and l5. The sprockets mounted adjacent either end of the shaft l1 are alike in diameter and number of teeth so that the elements being driven thereby are driven also in timed relationship. The lower' surface 19 of the case is cut away, as shown at 20,'to permit of the sprockets and chain ezt-:tending therebelow, and secured to the 'chains area multiplicity of sign boards 2l. Each of the sign boards have an outwardlyv extending supporting lug 22, disposed at either end thereof which acts as a journal for the' supportingpin 23, directly positioned upon the chain. Each of the sign board elements 21 is adapted and arranged for having a sign placed on oppositely disposed sides of the board so that when the same appears below the bottom of the case, the same may be readily observed from either side. The mechanism, as herein illustrated, has arranged thereupon signs as would be used in conjunction with a bath house or a manufacturer of lbathing suits and the like, and in order to further carry out this line of advertising, I have illustrated upon the end section 5 of the case, a panel in which is portrayed a bath pool or pond 2st, andjl place upon the stub shaft 9, a disk or disk segments 25 which are adapted for rotation with the rotation of the shaft 9, and l display upon the segment 25 one or more iigures 26, here portrayedas a diving nymph, so that but one of the figures' appear at a time and the disappearing of the same behind the pool, leaves the impressionwith the observer that the nymph is diving intorthe pool. The same may be portrayed upon a disk 27,

as illustrated in Fig. 5, and as the same is l,

rotated the diving nymph will appear to plungeV into the pool.

My invention is primarily intended for use in towns, villages and cities wherein density of trafiic is to be considered, and wherein signs are placed and maintained under ordinarices, and operated by license. In .many of the cities ordinances'prohibit the hanginj;- or maintaining of signs over sidewalks, where moving parts are in operation without safety devices being placed adapted to prevent the falling or dropping of the moving elements should the samebecome disengaged or disconnected fromits supporting element. l place supporting` elements 28 adjacent each corner of the ease structure and extend the same downwardly for a suihcient distance to permit the-cross bars 29 and the screen bottom 30 to clear the signboard 2l, when atl its lowest point. In the event of the signboard element becoming disengaged from the endless chain elements, the same cannot drop to the street but will be `maintained upon the supporting element 30. I preferably form the supporting Velement 30 of a relatively coarse screen or lattice work suiciently strong to support the signboard, and sulficiently open in its construction to permit of the passage of the light therethrough.

lt is highly desirable to illuminate the signboards as the same come into view and to intensify the light for a limited time only as the signboard comes into view and to. prevent the strong rays of the light beingdirected upon the signboard for the full'passage of the same' to view. Bestl results being obtained wherein a light V3l is placed below the sign on the side where the sign board travels toward the light and by placing a light 32 above the signboard where the signboard travels away from 'thelight Byv so placing the lights for the signboards, best results obtain and the signboards will be illuminated to the best Vadvantage for the advertiser. Each of the lights should be so placed as to be out of vision from the reader ofthe signs.

vWhere the bathing nymph- 26 is desiredA to appear as if diving from a springboard, the same may be accomplished as shown vin Fig. 6, wherein the spring boardis shown 33 and the nymph 34 is attached to an arm 35 directly attached to the driving shaft.

VVThe nymphl appears immediately above the spring board and is secured to the outer endV of the arm -35 similar in color to theiield the scene and 'thus appears t0 be 1111213091 tached and will Yin appearance Vdive into the water :is-illustrated. e Y

I do not wish to `be limited toa diving figure, as the same is susceptible` of'portrayingany number, orvarietyof objects of which this is intended as a single eX- ample. y

lilhile the form of mechanism herein shown and describedy is admirably adapted to fulfillthe objects priinarilystated. itis to be. understood that it is not intended to confine the invention to the one form of embodiment herein shown 'and described, as it is susceptible of embodiment in various for1ns,`all coming withinV the scope of the claims whichV follow. ,f
