APPARATUS FOR DISPLAYING ADVERTISEMENTS.
To all whom it may concern:
Be it known that I, GEORGE HOLT THOMAS, gentleman, a subject of the King of Great Britain, residing at Bookham Cottage, Great Bookham, in the county of Surrey, England, have invented new and useful Improvements in Apparatus for Displaying Advertisements, of which the following is specification.
According to this invention a number of vertical sheets of flexible material such as anvas are fixed together along a central. horizontal line while their top and bottom edges carry weighted bars, means being provided for raising the bottom bars and for periodically releasing the top bar of the sheet which happens to be in front, thus allowing it to fall to the bottom and expose a fresh surface to view.
A convenient way of working the apparatus is to provide at the back of the sheets continuously moving endless chains carrying hooks or lifters which come beneath the back bottom bar and gradually raise it until it reaches the top and pushes the front top bar out of its retaining devices and allows it to fall.
The retaining devices may consist of suitable springs.
Figure 1 is a front elevation (with half the case removed) of an apparatus constructed according to this invention. Fig. 2 is a section on the line 22 Fig. 1. Fig. 3 is a section on the line 3-3 of Fig. 1.
a is a case having a window 6 through which the advertisements are seen.
a are sheets of flexible material fixed together along the line 0 and having their ends fixed to bars 0 The ends of the bars 0 are grooved and move between guide plates (Z d, the plates cl being fixed directly Specification of Letters Patent.
Application filed. September 11, 1909.
Patented Mar. a.
Serial No. 517,326.
to the sides of the case while the plates cl are carried by blocks (Z fixed to them.
6 are endless chains driven by gearing from a motor 7 as shown.
0 are carriers fixed to the chains which when in their lowest position come beneath the back bottom bar 0 and then as they ascend lift it and ultimately force it past the retaining springs g and in so doing force the front top bar 0 past the spring bolts 7L and allow it to drop. 1
What ll claim is 1. Apparatus for displaying advertisements consisting of the combination of a number of sheets of flexible material fixed together along a central horizontal line and having weighted bars fixed to their top and bottom edges, and means for raising the bottom bars and periodically releasing the top bar of the sheet which happens to be in front.
2. Apparatus for displaying advertisements, consisting of the combination of a number of sheets of flexible material fixed together along a central horizontal line and having weighted bars fixed to their top and bottom edges, guides for the bars, an endless band carrying devices for raising the bars to the top of the apparatus, means for retaining the raised bars, and means for operating the endless band to lift a bar from the bottom of the apparatus to the top thereof and to cause said bar to move the top bar of the sheet which happens to be in front forward in the guides to allow it to drop.
