. BY 31$ ATTORNEQE Patented Nov. 17, 1931 i GEORGE LISS, Olli PATERSON, NEW JERSEY ADVERTISING APPARATUS Application filed February 14, 1931. Serial No. 515,725.

This invention relates to advertising apparatus and particularly to that class of such apparatus in which frames or, as ll term them, leaves are swung pivotally so as to e expose successively advertising matter carried thereby, after the manner of exposing the printed matter of leaves of a book by turning such leaves. I aim to provide an apparatus of this character which may be man- 10 ufactured at moderate cost and which will operate efficiently and'at the minimum expense of power.

According to my invention, combined with suitable supporting means are a turret revolii luble therein anda plurality of spaced leaves pivotally shiftable in the turret around axes arranged around and substantially parallel with the turret axis and each having limited shifting movement therein, whereby effort to 29 shift any leaf to its limit will, if continued after such limit is reached, turn the system as a whole. So that two of the leaves may be made to stand apart from each other, or

open, the leaves at any time at one side of a diametric plane coincident with the turret axis and those at the other side of said plane are normally urged to opposite limits, as by arranging the turret axis tilted or otherwise displaced from the vertical so that gravity 39 is active on the leaves. lVhile the apparatus, so constructed, may be operated by hand, I prefer to drive it automatically, as will hereinafter appear.

In the drawings,

5 Fig. 1 is a section of said means and system coincident with the turret axis;

Fig. 2 is a plan thereof;

Fig. 3 is a side elevation; and

Fig. 4 is a section on line 4.-4, Fig. 1, looking in the direction of the arrows.

Let 1 designate a suitable sup-port having an upright spindle 2 fixed therein. On this spindle, and supported as hereinafter stated,

is revoluble a turret 3 which comprises a sleeve 3a rotative on the spindle and upper and lower heads 3b and 30 fixed to the sleeve. In the heads at equal distances around and from the turret axis are pivoted the swinging frames or leaves 4, their axes being parallel with said axis. On these leaves the matter to be displayed may be arranged. Each leaf has a stop 5 which may engage the periphery of head 30 to limit the swinging motion of the leaf in either direction, as where when one leaf of two adjoining leaves is already at one limit and the other is moved to the opposite limit they will stand substantially alined (Fig. 2). Their tendency to remain in this position, and also of the remaining leaves at each side of a front-to-rear diametric vertical plane to swing back, is here the result of gravity, the whole system being tilted back somewhat (Fig. 3).

The observer may operate the system by hand, thus: One of the front two leaves is swung in the turret from its limit shown to its opposite limit, or till checked by stop 5 engagin head 30, whereupon continued cf fort applied to the leaf will turn the turret, that is, the system as a whole. For instance, manipulating the left hand front leaf in Fig. 2 to the right in this way will bring it first to the dotted-line position and then to the shownposition of the right-hand lea-f, leaving the first of these leaves and the next succeeding one in the new or open position of the two front leaves of said figure. To releasably hold the turret after each rotary movement thereof the lower head 30 may have notches 6, equal in number to the leaves, and engageable by a stationary pawl 7 having a rounded top upon which the head slides in rotating, said pawl being supported as will appear.

As illustrated and preferably, however, the system is operated automatically, thus:

8 is an electric motor whose rotary element includes an elongated pinion 9 in mesh with an internal gear 10a of a rotary table or actuator 10 having an upstanding picking stud 106, the actuator being movable up and down on the spindle subject to the coaction of a spring 11 and a. camway 12a of a cam 12 against which another stud 100 of the actuatorbears, said cam being pinned to the spindle and hence fixed. (The'spring may be interposed between flanged collars 13 loose on the spindle; and between the lower collar and a disk 1e resting on support 1 and between the actuator and the cam there may be anti-friction bearings 15). Assuming the actuator is rotated in the direction of the arrow in Fig. 2 the camway presents at the right side a sudden rise followed by a gradual depression (Fig. 3). Studs 10?) and 100 are so related to each other that when stud 100 encounters the rise stud 10?) will occupy a radial plane back ofthe forward left-hand leaf in Fig. 2 and forward of the next lefthand leaf; the extent of the depression of the cam is such that when stud 100 has reached the terminus of such depression stud 10?) will occupy a radial plane forward of the right-hand leaf in that figure; and finally the vertical displacement of the actuator, and hence of stud 10b, is such that when it is up the stud will project intothe horizontal plane of movement of the bottoms of the leaves and when it is down the stud will be below such plane. Pawl 7 may, as shown, be carried by cam 12, V

The automatic operation is as follows The system is shown in Fig. 2 in rest position, gravity holding the leaves at each side of a front-to-rea-r central plane, swung back, and

therefore, assisted by pawl 7, holding the system as a wholein said position. Assume the motor to be driving the actuator. tud 100 has just encountered the rise of the cam, so that the actuator rises and the stud 10b is raised and engages the left-hand forward leaf, thereupon shifting it on its own pivot to the dotted line position in Fig. 2 and then :(stop 5 ofthis leaf being now engaged with the turret) acting through said leaf to turn the turret so that said notch 6 clears the pawl 7 and until the next notch is engaged by this pawl, by which time stud 100 will have reached the terminus of the camway depression, causing depression of the actuator and hence of stud 107) so that the latter clears the mentioned leaf; this will leave this leaf in the position of the righthand one shown in full and have brought the next succeeding leaf to the position of the left-hand leaf shown. Each time the stud 100 is subjected to the influence of the camway this operation will be repeated, and in this way the leaves will be successively and the system as a whole picked around, coming to a pause between each two actuations and with the front two leaves during such pause standing in the ope-n? position.

Having thus fully described my invention what I claim. is:

l. A display apparatus comprising a rota-ry system including a revol'uble turret and a. plurality of spaced leaves pivotally shiftable on the turret around around and substantially parallel with the turret axis and each shiftable in the turret in either direction and limited as to such shifting independently of the other leaves and directly by the turret.

2. A display apparatus comprising arotary axes arranged system including a revoluble turret and a plurality of spaced leaves pivotally shiftable on the turret around axes arranged around and substantially parallel with the turret axis and each shiftable in the turret in either direction and limited as to such shifting independently of the other leaves and directly by the turret, and means, successively engageable with the leaves, to shift them successively in the turret and to their limits in one direction and thereby rotatesaid system.

3. A display apparatus comprising, in combination, asupport, a rotary display system rotative on the support and having spaced projecting members arranged around its axis of rotation, a driving mechanism including a rotary actuating device slidable axially of itself on said support into and out of rotary driving engagement with said projections, and means to shift said device into and out of suchengagement with said projections.

4. A display apparatus comprising, in combination, a support, a rotary display system rotative on the support and having spaced projecting members arranged around its'axis of rotation, a driving mechanism including a rotary actuating device slidable axially of itself on said support into and out of rotary driving engagement with said projections, and cam-including means to shift said device into and out of such engagement with said projections.

Ardisplay apparatus comprising, in combination, a support, a rotary display system having spaced projecting members arranged around its axis of rotation, a driving mechanism inc-luding'a rotary-actuating device slidable axially ofitself back and forth into and out of rotary driving engagement with said projections, and a spring and cam, acting oppositely to each other on said device, for efiecti-ng the back and forth sliding thereof.

In testimony whereof I affix my-signature.
