This invention relates to a changeable advertising and display apparatus operable by a wind vane to move certain parts of an advertising panel successivelyinto a predetermined display position on a bill-board or the like adapted for use on public highways. a 1 1 The main object' of-the invention is'to provide a device of the ,character 7 described eachof which is designed to hav which is operable by the rotation of a wind vane to move an advertlslng panel succes-.

sively from one of several predetermined display positions relative to a fixed display opening in thebill-board or the like.

Other. objects of the invention will become apparent as the detailed description thereof proceeds. I

In the drawings the invention is shown as a structure comprising a pair of standards 1 and 2, connected by a base 3 and a top rail 4; all framed together to support a panel board 5 adapted to receive advertising matter and provided at its center I with a display aperture .6. I

The back of the panel board 5,, (Fig. .2), has a pair, of angleirons 7 and 8 fixed thereto to formguideways for slida'bly supporting and guiding a panel 9, which, as shown in Fig. 1, is divided into three sections 10,. 11 and 12, each of which is equalin area and outline to the display aperture 6; Land ing matter displayed thereon.

In order to move the panel 8 so as to cause e advertisthe sections 10, 11 and 12 to'appear fully and successively at the display opening 6,

the panel 9 has a pair'of angle iron brack-1 ets l3 and 14: secured to opposite ends of the back thereof andadapted to be engaged by cam hooks pivotally secured in certain positions on-the endless sprocket chains; 17 and 18. In order to move these chains in opposite directions past the back of panel 9, a pair of vertically disposed shafts 19 and20 are rotatably mounted in hearings 21-2223 and 2l2526, respectively,

suitable secured to the back of the standards 2 and 1, respectively.

The bearings 21 and 24am step bearings in which the lower ends of shafts 19 and 20 are supported rotatably; and, the bearings 22-23 and 25-26 are spaced apart to receive grooved, pulleys27 and 28 fixed to shafts 19 and 20, respectively. These pulleys 27 and 28 are rotated in opposite directions by cables 30 and 31, respectively extending around the double grooved pulley Y 32 which is fixed to a shaft 33 supported rotatably in bearingsBl and 35 fixedto the back of the top rail 4, the cable 31 being crossed to ensure rotation of shaft 20in the opposite direction to the direction of rotation of shaft 19. A windxvanev' of any suitable construction or type is fixed to the upper part of shaft 33 in order to rotate said shaft.-

Sprocket wheels 36 and 37, of which the heel 36 is fixed to shaft 19, and wheel 37 is rotatably mounted on shaft between the sleeves 38 and 39. The chain 18 is rotated by sprocket wheels 40 and 41 of which the wheel 10 is rotatably mounted on shaft 19, and the Wheel llvis fixed to shaft 20 to rotate therewith. This construction, obviously, ensures that the chains 17 and 18-will move in opposite directions pastrthe back of the panel 9 regardless of the direction of rotation of shaftBS by the wind vane V.

The "chain 17 moves horizontallypast thej back'of panel 9 and centered betweenthe upper and lower ends of the angle 1ron 13.

A hook member 42 is pivoted 'on the upper edge of the chain 17 and a similar member 43 is pivoted to the lower edge of said chain 17. These members 4-2 and lizare shaped symmetrically about their pivot axes in order to adapt tlienifor s'liding in either direction along guideways and 45"formed on a cam plate 46 having one end bifurcated and the fur'c ations thereof bent around shaft 19 on opposite sides of the wheel 36.

At-one end of the bill-board, the cam plate "46 is supported by'stra'p brackets 47 and i -8 19 is adapted to contact with either extending between the stretches of the sprocket chains 17 and 18 and suitably secured to the back of the panel board '5 and is formed with two contact surfaces 19 and 50 of different lengths. The upper surface edge of the hook member 12 and'keep it in moving :c'ont'act with the angle iron 13 for the full lengthof the contact surface 19. The length I et surface 459 is substantially equal in length to the Width ofeach of the sections 10, 11

' and 12, and surface 50 is twice this length,

in order to effect the movement ofpanel 9 necessary to "locate the sect-ions properly in the displayapert-ureG. I s

j At'the other 'end of the bill-board, a cam plate 51, formedto pair with the cam plate 46,'is supported by'strap brackets'52 and extending also'between the stretches of the s rocket chains 17 and 18 and suitablysecured to the back of the panel board This plate 51 is formed Witlr'tWO contact surfaces 54 and 55 of difierent lengths, the

' 1e'ngth 0fsurface 55 being equaltothe width of eachfof the sections 10, '1' 1 and 12, while the length of surface 55 is equal to twice thisavidth, in order to effect proper successive movements of the display panel-9 relative to the opening 6.

The @uppersurface 54 is adapted to contact With'eitl'ier edge or the hook member 56 pivoted to the upper edge of the chain 18; while the lower contact surface 5511's adapted to contactwlth'the hook niember 57 pivot'ed'to thc lower edge'of tl1e cliain18.

These hook members are symmetrically shaped relative to their pivot axesan order to adapt them for sllCllng":COIltitC'E'lD-Blthfil' direction on i the contact surfaces of the plate 51.

The spacings between the hook members- 42 ant 453 on chain 17, and between members I 56 and 57 on chain 18 determine the intervals between successive movements of the,

display panel 9 at any given speed-0f rotation of the wind vane V. V drawings, these spaces are eachequal to onefourth of the entire length of each of the chains. Obviously, the distance between the shafts 19 and 20 must at least be equal to volves nothing more than the ordinary skill of-the mechanics to design a board having any desired number of display sections and operated by mechanism'similar in principle of operation to that disclosedi V ftivill be noted that each of the contact plates 16 and 51 has its Wide end bifurcated and bent around the shaft-s 19 and 20, re-

;spect *e-lv, "iththe-furcations arranged on opposite .116301 the sprockets 36 and 11,

"respectivelyf While this construction is not actually necessary to the operation ofthe device, it does afford a-support'ing means to prevent lengthwise movements of the, 510a plates 46 and 51onthe back of theboard. The dlsplaypanel 9'is provided on its bottom edge with'ball casters 58, 59 andGO,

As shown the equidistantly spaced apart 'to seat'in three of the correspondingly spaced" recesses 61,

62, 63, (i l and 65." These recesseshold the panel boardyieldingly fixed in any of its three positions. during the intervals When it is not being mored by the hook members 4-2 and 43 or and 57. Of course, any de} sired number of casters may be used pro- 'vi diJ-g the number of recesses be increased or 1 tio ng of the display panel 9.

decreased to take care of the proper posi- In operation: Vl hen the shaft33is rotated in either direction by the action of Wind on the vane V, it is obvious that'the shaft 19 will be rotated by cable 30 in the same direction; andshaft 20 will berotated in the opposite direction by cable 31..

Referring now to Fig. 4, where the panel 9 shown with the section 11 centered in the display aperture 6 and with the hook bracket '13 in orderto move panel 9 With the display section lfi intodisplay position in the aperture 6. As soon as angle iron13 reached its dotted line position indicated member e13 ust engaging the angle iron 3 board.

in Fig. t,the'hook member43 reaches the end of contact surface 50 and swings back to dotted line position. The panel 9 now is positioned as shown in Fig. 5 and chain continues to rotate without moving the panel 9 because the channel iron 13 is clear of the cam plate 46. However, the angle iron 14 is located in front of cam plate 51, and the hook member 56, riding on cam surface 54, engages channel iron 14 to move the panel toward the display opening 6; and the hook 57 afterwards moves the panel from center position to the extreme left of the The cam hooks on the chains 17 and 18 operate successively on the angle irons 13 and 14 to move the panel 9 intermittently and through predetermined distances for the successive display of the sections 10, 11 and 12 of the display panel 9 before the display aperture 6.

Since the cam hooks 42, 4:3, 56 and 57 are symmetrically shaped, it is obviously immaterial which direction the shaft 33 is rotated by the wind. The display panel is reciprocated back of the aperture 6 by the successive operation of the two chains 17 and 18 which rotate continuously in opposite directions. r

It will be obvious from the disclosure herein that I have provided a novel changeable advertising exhibitor which involves no expense for operating power, and which can bevery easily and cheaply manufactured.
