2 Claims. (01. 40-39) This invention relates to improvements in the class of card, picture, and sign exhibiting, and its objects are as follows:-

First, to provide a rotatable advertising medium in which the hinged leaves or vanes partake of what might be called an opening and closing movement with respect to the rotor as the latter isrotated, the two-fold purpose of this operation being to receive the impact of the wind whereby the rotor is moved and to heighten the interest in the advertising matter.

Second, to utilize the hinge leaves or vanes somewhat on the order of brakes for the purpose of preventing the rotor from turning too fast and thereby tending to maintain a uniform speed of rotation of the elbow regardless of the wind velocity.

Third, to connect the outer vane posts with the radial arms of the rotor by means of elbows which can be turned either into up or down positions with respect to the arms so as to hingedly support the vanes either above or below the arms.

Fourth, to make the vanes sufiiciently longer than the distance between the axial centers of the center post and the posts by which the vanes are carried to cause the free ends of the vanes to engage the center pivot post during a period of the rotation of the rotor, thereby holding a given vane fixed with respect to the rotor so that the wind can impinge thereagainst and cause rotation.

In the drawing:

Figure 1 is a side elevation of the improved ad- I vertising device, a typical foundation being shown in section.

Figure 2 is a horizontal section taken on the line 2-2 of Figure 1.

Figure 3 is an enlarged view of the center construction of the device, the center post-being partially in section and in elevation, and portions of the rotor being in section.

In carrying out the invention provision is made of a center post I which may consist of a pipe, as shown, or a cylindrical rod of any available material. It is not essential that the post he cylindrical for its entire distance, this being necessary only at the top because it is there that the rotor is rotatably mounted. The post is intended to be fixed in any convenient way, a typical foundation 2 consisting of a cement casting in which the post is embedded.

The rotor, generally designated 3 is mounted on top of the post I so as to rotate quite freely. It is assumed that the direction of rotation is low a six-way cross 1, the continuation being herein called the lower bearing sleeve which is designated 8. As far as function is concerned, the two sleeves 4 and 8 are one, the cross 1 merely being connected in a short distance from the bottom to balance the rotor structure. It would be entirely within the principle of the invention to make 4 and 8 in one piece, and to attach the six-way cross, or its equivalent, by means other than threading as shown.

According to the present construction the sleeves 4 and 8 are screwed into the vertical outlets of the six-way cross. Each of the four remaining outlets has a radial arm 9 screwed therein. At its outer end each radial arm has an elbow In which can be turned either up or down. A post H is screwed into each elbow, and the posts point either up or down depending on which way the elbows are turned. The free ends of the posts are closed by caps l2, and these become bearings for the leaves or vanes in case the posts are turned down instead of up. At present the elbows l serve as bearings for the vanes. This ends the rotor construction.

The structure of the vanes is as follows: Each vane I3 is made of sheet metal or any appropriate equivalent. It is intended to have advertising matter M (Fig. 1) applied on one or both sides. The vane is not necessarily rectangular as shown, but may have any form or outline desired, for example that of bottles, animals, vehicles, etc., as long as the over-all length of the vane, Whatever its design, is such as to reach from the axial center of the respective post slightly past the axial center of the center post.

Hinges l movably connect the vanes with the outer posts II. The vane hinges turn on these outer posts as the rotor 4 rotates, and when the free ends of the vanes engage the center pivot sleeve 4 as at l6 (Fig. 2) the vanes become fixed with respect to the rotor for a period and thus provide means against which the wind impinges so as to drive the rotor in the clockwise direction a (Fig. 2).

The operation is readily understood from what has been stated, and this is briefly amplified as follows: A direction of the wind is assumed to be as indicated by the arrows b. As soon as the vane I3, now designated c for the purpose of distinction passes a little beyond dead center the wind pressure will catch it and turn it on its post until it assumes the position of the vane d. From thereon for approximately one-half a revolution of the rotor 3,-said vane will trail in the wind and will have somewhat of a braking efiect that will prevent the rotor from turning too fast and thus wreck itself in a high wind. The braking efiect of the trailing vane tends to maintain auniform speed of rotation of the rotor regardless of the wind velocity.

As soon as a given vane reachesthe position e its free end engages the side of the pivot sleeve 4, and from then on the vane stays fixed with reference to the rotor, serving as a paddle or blade against which the wind impinges, causing the clockwise rotation as already pointed out. This periodic relative fixture of a given vane and its trailing action through an arc of the rotation of It is contemplated top and bottom.

I claim: 7 1. An advertising device comprising a fixed center post, a rotor rotatably mounted on the post, said rotor consisting of a center sleeve structure fitted down over the post, a cap included in said structure and a thrust bearing between the cap and the post, radial arms attached to the sleeve structure,-outer posts in upright positions on the radial arms; and vanescarried by the outer posts, each vane having hinge means by which it is turnably carried by the respective post,

said vane having sufiicient distance between the hinge means and the center post so that the free 'end'of the vane contacts the sleeve structure during=a portion of the rotation of the rotor 2. An :advertising device comprising a. fixed center post, a rotor and means by which it is rotatably mounted on said post, said rotor including radial arms, outer posts, an elbow connecting 'therespective posts with the respective arms and being turnable so that the respective post points either up or down, the free end of each outer post having a closure.,.cap,.said cap andlthe respective elbow serving asbearings; and a vane carried depending on ".theposition in which the elbow'is turned.
