Patented Feb. l1, 1930 PATENr OFFICE EDWARD nonne, or (nonno, ILLINOIS Munrirrn nnvonvine SIGN Application led April 11,

This invention relates to revolvingsigns, and more particularly to a multiple revolving sign device of a type particularly adapted for the display of advertising and pictorial cards. The object of the inventionis to provide an improved revolving sign display. device `of comparatively simple and inexpensive construction, with means to instantly remove any desired advertising or pictorial card from an indefinite number `of other cards within the device,'\ and to` immediately `replace the removed card `with another card.; Anotheirob'ject o f the invention is to provide a simplified mechanism and construction in aidevice of the kind described for retaining andrevolving multiplicity of diver-sedie# play or advertising cards, etc. i

"Otherobj ects and advantages of the method and construction herein employed will ap pear more `fully :in the details hereinafter set forth, reference being` had to the accompanying drawings, in which, s

In' the drawings .wherein similar characters of referenceindicate correspondingparts in `the several views of the preferred form of `the invention, Av Adesignates a housing sub stantialfly trapezoidal shapedenclosing certain partshereinafter described-moimted on a baseplate 10 te which the housing A is de y tachably seciiredby'screws 11, threaded thereto'.- Asbest shown in Figure 1, the housing A is' providedA with an opening 12 form`ed in a fronti inclined walls 13 of the housing, `the open-ing. serving as means through which `the advertising` cards 27 are swung Vand viewed. `As `will be seen hereinafter, the front v wall` 13 ofthe housingA plays an important `part in retaining the display cards 2T yuntil 1929. Serial No.` 354,189.

such time asthe latter have been temporarily flexed or bent sufficiently to be carried through the window or opening A. t

. On the base plate 11 a pairof yolemembers 141, 14 are mounted with which are integrally formed ournal supporting brackets 15,116 on the spaced arms 15, 16', of which apertures are provided in which set screws 17 locked by nuts 17 are threaded, the set screws securing the supporting journal sleeves 18, 19 1n which stud shafts 20, 21 fastened to drum 22 are revolvably supported. Discs 23, 24 are fastened to the opposite ends of `drum 22` by screws `25, these discs having a plurality of holes 26 arranged on the marginal border thereof. Asforming animportant part of my invention, the `display cards 27which may b eof any desired type, pictorial or advert1s1ng`,are clampinglysecured in longitudinally folded or crimped strips of metal 28, preferably of a somewhat resilient nature for a purpose which will shortly appear, the ends of themetal strips 28 being individually inserted in opposed holes of the discs 2?, 24.4 A gear 29 is secured to stud shaft 20, the .gear 29 being intermittently engaged by a plurality of pins 30 fastened` in `a hub 31 detachl ably secured on a shaft 32 by means of the cap screw 33. Coacting withgear 27 and preventing reverse movement thereof isa detent 34 preferably of leather or fabricated material, the deteiit 3e being mounted on an arm 35 secured to yoke member 14. The shaft 32 is operatively connected to the armature shaft of a motor 36 through a system of reduction gearing (not shown), the reduction gearing and motor being of Vconventional type and not in themselves forming a part of the present invention. Themotor 36 is au propriately secured to a bracket 37 which is fastenedto a supporting yoke 38 ailixed to the base plate V11. y

a Assuming the motor 36 to be connected to a source of `electric energy, and the shaft 32 slowly turning through `the intermediary of `theinotor reduction gearing, the teethif gear 29 will be intermittently engaged by the pins 30, and the drum 22 will be swung through a portion `of an arc sufficiently to tilt one of the *cards 27" from its upper position againsttheV y inner side of the upper part of the wall 13,

as clearly shown in Figure 2. On further actuation of the drum through the intermediary of the gear 29, the card immediately adjacent the inner surface of the top of the wall 13 will be preliminarily bent or flexed into an arcuate shape and then flipped through the opening 12, whereupon it will be temporarily supported against the lower part of the front wall 13 immediately beneath the opening 12, where it may be viewed for a predetermined space of time. It will be possible by changing the speed in the motor, the ratio of the reduction gearing or by adding to or subtracting from the number of pins on the hub 31 to increase or decrease the time interval during which the card 13 is supported on the front wall. As illustrated I have found it suicient to provide for the passing of twelve of the cards through the opening or Window 12 per minute, thus allowing eachof the series of cards 27 to be viewed five seconds. As the drum 22 is intermittently turned, the card resting on the'lower part of the front wall 13 will be covered by the card next adjacent in the rear thereof. `From an inspection of Figure 1 it will be seen that as the drum 22 turns, the cards 27 pivotally attached to the discs 23, 24 are swung through the opening 12, there being two or three' cards beneath the uppermost,` supported on the eX- terior bottom part of the front wall, until the discs 23, 24 have been swung through an arc sucient to withdraw the lowermost card from theV group of three or four cards positioned` on the front wall 13. By inspection ofthe discs 23, 24, it will be seen that in proportion as these discs are made larger or smaller, a greater or lesser number of display cards may be accommodated, the present device being designed to carry and displa upwards of twenty cards. I have found it dyesirable to form the strips 26 of a metal -possessing resiliency, it being observed that any of the cards may be removed by merely flexing the strips 26 in the fingers of one hand sufficiently to withdraw the ends thereof from the opposed holes 26 in the respective discs 23, 24.l When it is desired to replace the card, the same procedure is followed, one end of the strip may be inserted in one of the discs 23, and the body of the stripthen fiexed to permit the other end thereof to enter the opposed hole of the other disc 24 after which the strip is released and the card then assumes its proper position relativelyto the other cards.

While I have described andV illustrated a preferred form of my invention, it will be understood that the details as set forth are `susceptible of considerable modification and chan e without departin from the spirit or sacri cing any of the a vantages of the invention; hence, I desire to be understood that the invention is not to be confined to the predetails of construction, save to the extent these are circumscribed within the scope of the appended claims.
