The dampers 58 are connected by means of the damper rods M to a common point :35 on the bell crank lever 26, and are so connected that when one damper is open the other damper will be closed.

A magazine M having specially prepared pages is used. with display device. The magazine M consists of a plurality of sheets of paper or other sheet material bound together in any suitable manner after the manner of a pamphlet, book or the like, so that pages are formed which can be turned about the binding. In the particular form shown, the magazine M is divided into pages by a solid binding midway between the side edges of the pages but it will be readily appreciated that a loose leaf binding or any other suitable type of binding could be employed for the purpose. Perforations are formed in the Various pages adjacent their free side edges. The top page $6 is shown with perforations Q? and the page is immediately therebeneath is provided with perforations 59 which are offset lengthwise of the page from the perforations or apertures in the uppermost page 4%. It is important that the perforations be staggered or out of alinement in adjacent pages throughout the magazine M. The shape of the various perforations and 1 9 is capable of wide variance and the size, number and location of these perforations are subject to considerable variation. The size, number, type and position of the particular perforations provided depend very lar ely upon the size and weight of the particular page and the rapidity of turning movement of pages that is desired, as will be brought out later.

Attention should be called to the fact that a double arched member idea is secured to the bottom 56 of casing C to lie between the two vanes and H.

When it is desired to operate the device, a magazine M, the pages of which have been properly perforated as described, is placed within the casing C to rest as upon the right hand arch of the double arched member Ma and the right hand vane ll. Before insertion, the magazine is closed up with the binding located adjacent the center or valley of the double arched member Ma. To insert the magazine in the casing C, the glazed hinged door H is raised and after the magazine has been put in place the door is closed. The motor 22 driving fan iii is then set in operation whereupon, assuming that the damper M is swung to the right as shown in Fig. 3, air will be delivered from the fan 25 through the left hand branch of the conduit 28 to be directed into casing C in a downward and inward direction from the left hand inlet i9. This air impinges against the left hand or swinging edge of the vane 3 which will at this time be exposed and, as best shown in Fig. 6, the air stream will cause the vane to be lifted upwardly from the full line position there shown to the dotted line position there shown, the vane being of light weight to permit of this movement when no part of the magazine M is resting thereon. The left hand spring 53 partially counterbalances the weight of the vane 3? and the lever 35 so as to readily permit of movement of the vane. The air entering the casing C from the left hand inlet l9 having struck the vane 3? will carry completely across the casing to exhaust therefrom through the screened opening H at the right end or" the casing, the right hand damper 58 being always open when the damper 23 is swung to the right. Of course air exhausting from the casing C passes into the fan chamber of the cabinet 9 and is recirculated by the fan 2|.

As the left hand vane 31 lifts to the dotted position shown in Fig. 6 the action of the vane imparts movement to the lever 35 and rod 33 thereby swinging V-shaped control lever 28 to the left. This will cause the toothed member 30 on the right arm of lever 28 to be thrown to such a position that as the cam 3i rotates under influence of the motor 22, this toothed member is engaged by the notch in the cam with a resulting pull on the lever 28, bell crank 26 and the levers connected thereto. The bell crank 26 will then be swung to the left on its pivot 27 and the link 25 will swing the air flow damper 23 to the left to deflect the air from the fan into the right hand branch of air conduit 29. As the bell crank 26 swings to the left the left hand rod M. will open the left hand damper 58 therefore closing left hand screened opening ll, while the right hand rod is will close the right hand damper l8 controlling the right hand screened opening ll. Air is then directed into the casing C from the right fork of the air conduit 26 through the right hand opening it), and exhausts from the casing through the left hand screened opening H. The air upon entering the casing C will be directed against the right edge portions of the pages of the magazine M and causing the pages to be turned to the left one at a time.

The movement of a page of the magazine M as it is turned is best shown in Fig. '7. In this particular view, the air stream is shown entering the casing C from the left inlet is, it being assumed that damper 23 is swung to the right, left hand damper iii is closed and right hand damper i8 is opened. The air admitted to the casing from the left opening it) first strikes the upper left hand page of the magazine on the portion thereof wherein the perforations of that page are located. Most of the air is deflected from the top of the page across the casing C to exhaust from the right hand screened opening ll. Some of the air, however, due to its angle of projection from inlet 89, strikes edges of the page formed by the right sides of the perforations and exerts slight force on the uppermost page tending to push the page in the direction of air flow. This force is supplemented somewhat by the air stream striking almost invisible slight irregularities of the page. A portion of the air works into the perforations against the page immediately underlying the left top page tending to force down the portions of the underlying page immediately below the perforations of the uppermost page. The air working into the perforations of the uppermost page gradually spreads slightly between the two pages to impart a raising force against the bottom of the uppermost page and a downward holding force to the immediately underlying page. The curvature of the pages as viewed in full lines Fig. '7 at the area Where the air first strikes the uppermost page assists in producing this raising force against the under side of the uppermost page adjacent the perforations.

'The uppermost page accordingly begins to slowly bulge upwardly near its left edge and, as this bulging movement continues, more air works through the perforations to exert pressure upwardly against more area of the under surface of the uppermost page and downwardly against more area of the upper surface of the next underlying page to produce an increasing bulge in the left hand portion of the uppermost page. The uppermost page slowly raises or bulges upwardly to take approximately the position shown in dotted lines Fig. 7 and designated by the numeral 5d. Of course during this time period such printed or illustrative matter as may appear on the upper surface of the uppermost left hand page and of course the upper surface of the uppermost right hand page of the magazine can be viewed by an observer through the glass of the door ii.

The upper"- reached the tion will more rapidly rise ,n shown in dotted lines Fig. 7. ,ion i it will be noted that the edge of the upper-mo t page has slid considerably to the right of its original position. While air continues to work through tie perforations of the uppermost page to exert upward force on the under side of the uppermos and downward force on the immed atel; L erlying page, air admitted through the iniet ening it and working against the bulged up most page exerts rapidly increasing force tending to swing the page to the right, or, in other words, turn the page. Eventuaily, the face edge of the uppermost page flies up against the glass of the door ii to an oximat v the position indicated page is then subll force of the air stream is very rapidly to the right of the centrai binding to drop onto the right hand page which has last previously turned. ped at the fight of the magazine bib betas. 1 the page being turned and the pa which has just previously been turned may escape readily through the openings i t to permit the being turned to lie closely and smoothly against its predecessor in full contact therewith, thus leaving the right hand portion of the magazine in proper neat position to permit of the reverse turning of the pages during later operation of the device.

More apertures l6 provided in the front side wall it of the C than in the rear side left hand page having slowly wall because the e rests in the casing at an inclined angle relative to the horizontal. Due to the weight of the magazine and its natural tendency to slide a ainst the front side wall is of the casing C, there friction between the bottom edges of the ma azine pages and the front side wall it than betw the magazine and the rear side wall it. the provision of the in the front side wall it, ore air escape through these apertures th '1 through the fewer number of apertures in the rear side wall it, and the retarding frictional force on the bottom edges of the magazine pages is thus overcome. Attention should be called to the fact that the apertures of the left underl g the page being turned not exposed to the direct action of the air stream until after the being turned; bulged up to approximately the posi- 7. The staggering of apercages prevents the air from working thro h ti apertures of more than one page at un the free go of the page By umber of apertures tures in ive the top edges of turned forces the underlying page down to ensure the complete turning of the overlying page before the underlying page can be turned. It is absolutely impossible for two pages of the magazine to be turned at the same time unless this should be intended. If, for any reason, it should be desired to turn two or more pages at a time this could, of course, be accomplished by producing similar aligned apertures in the particular pages that it was desired to turn together.

Of course, the pages will be successively turned one at a time in one direction until all the pages have been turned. When this has been accomplished, a reversal of the direction of the air stream is brought about automatically, as generally previously described, by the rising movement of the particular vane 33 or ll exposed, whereupon the pages will be successively turned in the opposite direction. The apparatus thus continues in operation first turning the magazine pages in one direction and then in the opposite direction.

T e interval of time that elapses between the turning of one page and the turning of a succeeding page of a magazine may be accurately controlled by varying the size, number, type or positions of the apertures of the different pages. The size, type, thickness and quality of the paper or other sheet material forming the magazine used has a great deal to do with the rapidity of turning movement of the pages. The weight of particular page has much to do with the rapidity of turning movement of that particular page. The amount of ink on the chiferent similar sized pages produces difierences in the weight of pages formed from similar paper stock. Accordingly the apertures in an individual page are cut and provided in. proper number, type and position to ensure the desired time period of exposure of that page to view through the glass door ll, before the page is turned. As the apertures are increased in size and in number and as the apertures are located more in line with the direction of the initial impingement of the air stream. against the page, the more rapidly will the page be turned and conversely.

In the particular embodiment of the device shown, the force of the air acting against one of the vanes 3'! or M is insufiicient to permit such a vane as it rises to directly swing the damper 2t and the two dampers l8. Thence the motor acting through the cam 3! is employed for this purpose. It will, of course, be appreciated that other mechanical structure can be readily provided for accomplishing this same end.

I have described the construction of my apparatus as well as the method of perforating the pages of a magazine or similar article to be disayed. It may be possible, however, to similarly display a magazine with other apparatus. For that reason, I desire also to protect the various novel steps of the method of displaying magazines and the like which includes forming perforations adjacent the edges of the pages of the magazine in the manner described above, placing the magazine upon a support, directing a stream of air against perforated portions of the of one side of the magazine to cause the pages to turn over one at a time in one direction, controlling the time interval between the turning of successive pages, and then directing a current of air against perforated portions of the pages at the other side of the magazine to cause the pages to turn over one at a time in opposite direction.

When the word magazine is used throughout the specification and claims, it is to be given a broad interpretation. t is intended to include books, pamphlets, bound advertising, display 1 sheets,.newspapers, etc.; in other words, any kind of arrangemen of sheets which are bound or anchored together so that the individual pages can be turned.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the various parts and in the various steps in the method disclosed, without departing from the scope of the invention.
