Upon this cover plate'the metal plates is snitably securcd and represents tivo pages'of'an open boolg said plate bearing upon itssurface at opposite sides of center suitable advertising matter." This plate'at its upper and loweredges and at" its approximate center has-spaced tongues '9' struck "therefrom-and"between these tong'ues'fthe "'redu'cedendsof a metal strip indicated n10 are adapted to be trictional'lj engag'edfl To one edge of th is strip the platen representing a book leaf is hinged as-at-'*12, said plate likewise bearing on its opposite 'side" faces, suitable advertising matter.

Within the housing or casing theentire mechanism for turning the hinged leaf 11 in relatively opposite directions at the end of suitable time intervals to display the advertisements carried thereby, is contained. This mechanism includes a member 13 which is pivotally mounted as at 14 upon a suitable supporting bracket 15 fixed to the bottom wall of the casing 5. This member has parts extending at substantially 90 with respect to each other from the pivot 14 and each terminating inan arcuately curved arm 16. These arms are adapted to be moved through aligned openings indicated at 17 in the front plate 7 of the casing and the plate 8 secured thereon which are located at relative opposite sides of the hinge 12 of the leaf 11.

The bracket member 15 is provided at its central portion with a horizontally extending slot having a central curved section 18 and the straight end sections 19 in alignment with each other. The edges 20 of the member 13 extending at right angles to each other are respectively disposed in coinciding relation with one edge of the respective end portions 19 of this slot in the different positions assumed by the member 13.

The member 13 is automatically operated by suitable thermdelectrically controlled means contained within the casing 5. In the embodiment of the invention herein illustrated, this means includes an expansible and contractable resistance wire 21 which is turned around a'selies of sheaves or pulleys 22 losely mounted on the shafts 23 mounted in suitable spaced brackets 24 secured to the bottom wall of the casing 5 at the opposite ends thereof.

One end of this resistance wire is fixed as at 25 to a fixed part on one of the shafts 23. The other end of the resistance-wire is suitably attached to an insulating piece 26 with which one end of a coil spring 27 is connected, the other end of said spring being attached to one of the brackets 24. Current is supplied from the house circuit through the wires 28 and 29, the wire 29 being connected with the resistance element 21 adjacent its fixed end 25. The other wire 28 is connected with one pole or terminal by a suitable type of snap switch indicated at 30, the other pole of which is connected by wire 31 with resistance element 21 adjacent to its opposite end. As shown in Fig. 9, the switch includes a pivotally movable contact carrying member 32 which in one position is adapted to connect the pole terminals and thereby close the circuit. This member is operated by and is also movable independently of the member 33 which ispivotally mounted within the switch casing as at 34. To this member 33, the upper end of a rod 35 is suitably connected, the lower end of said rod cooperating with the edges 20 of the pivoted member 13 and being movable in the horizontal slot 1819 of the bracket plate 15.

This rod is connected with the upper strand or the resistance wire 21 by a sleeve of insulating material 36 loosely engaged on said rod and carrying a set screw 37. The upper part of the sleeve is also provided with a slot 38 intersecting the bore thereof and opening on the upper end of the sleeve, said slot at its base being provided with a recess 39 in one side wall. This slot receives the resistance wire strand and upon tightening the set screw 3'? against the rod 35, the strand is bent and forced into the recess 39 while the sleeve 36 is thus rigidly secured in any desired adjusted position along the rod 35 in spaced relation to the pivot 34.

The circuit wires 28 and 29 may extend through a suitable outlet bushing indicated at 40 in the back of base wall of the casing 5 for connection with a suitable plug for engagement in a socket or wall outlet. The

rear wall of the casing is also preferably provided with a ventilating opening shown at 41 so that the heat generated by the resistance wire 21 may find a free outlet.

The rear wall of the casing may be extended below the bottom wall thereof and provided with suitable supporting members indicated at 42 and to the rear of the casing an adjustable leg or prop 43 is pivotally attached at its upper end as at 44 so as to support the casing in a desiredinclined'position. To retain the prop 43 in its adjusted position, I may provide the chain indicated at 45 passing through a suitable eye 46 on the prop 43 and having one of its ends permanently attached to the rear wall of the casing, and said casing wall being provided with a hook indicated at 47 with which the chain adjacent to its other end may be connected.

In the operation of the device as above described, in the position of the rod 35 as seen in Figs. 1 and 90f the drawings, the switch is open. Assuming that this operation has just taken place, and due to the resistance generated heat, the wire 21 has fully expanded while the spring 21 is contracted, as the resistance wire cools, it will contract and gradually reduce in length, thereby pulling upon the spring 27 and expanding the same. The rod 35 is thus also moved to the left from the position shown in Fig.1, and during the first part of this movement, the lower end of said rod will move freely in the right hand end portion 19 of the slot in the bracket 15 from the position shown in Fig. 7 of the drawings. V

The snap switch as shown in Fig. '9 is of the spring toggle type and during this first part of the movement of the rod 35, the movable switch member remains in the open position while energ is being stored in the toggle spring. Continued con- Cil quickly throw the movable switch member 32 to the closed position'which thereby also imparts a quick movement to the lower end of the rod 35 which bears against one of the edges 20 of the member 13. As this end of the rod moves in the curved part 18 of the slot in the bracket member, the m mber 13 is moved from the position of 7 to the position shown in Fig. so that one of its arms 16 is moved outwardly through the opening 17 and acts against the pivoted or hinged leaf 11 to move the same through an arc of substantially 45 and from a position in parallel relation to plate 8 to a position. in a plane slightly beyond a 90 angle with respect thereto or past the center of gravity so that said hinge leaf 11 will then drop or fall to the dotted line position snown in Fig. 6 of the drawings.

Since the circuit has now been closed, the resistance wire 21 will again expand and progressively with such expansion of the wire, the spring 27 contracts, thus moving the rod 35 in the opposite direction, or towards the position of Fig. 1. In the first part of such movement, the lower end of rod 35 moves to the right in the end portion of the slot in bracket and is engaged with the angularly extending edge of member 13, at which time the spring toggle of the switch operates to move the switch member 32 to the open position, and continue the movement of rod 35 to thereby operate the member 13 in the reverse direction and cause the other of the arms 16 thereof to engage the hinged leaf l1 and turn the same to it former position.

These operations are then repeated a above described at the regular intervals 0 time sufficient to enable the advertising matter on the surfaces of the movable leaf l1 and of the tired plate 8 to be read by the ob- 5 server. The length of time elapsing between successive operations of the member 13 may be varied or changed within certain limits by longitudinally adjusting the sleeve 36 along the rod 35 towards or from the pivot 34.

From the foregoing description considered in connection with the accompanying drawings. the construction of my improved advertising device as well as the operation thereof and its several advantages in practical use will be clearly understood. It will be seen that by the provision of electrical re sistance control means for actuating the leaf turning movement of the kind above described, it is possible to very compactly house or arrange all of the operating parts within a relatively shallow housing or casing so that the device may be mounted and arranged in a relatively small space in a show window for use in connection with display advertising. Also, in view of the very simple form and construction of the several elements employed, it will be apparent that the device can be manufactured and sold at relatively small cost and will also be posi 've and reliable in its operation and not liable to get out of order.

I have herein shown and described an embodiment of the invention which I have found to be entirely satisfactory i practical use. Nevertheless, it will be und t the essential features of my invention in susceptible of more or less modification in form, construction and relative arrangem nt of its various pa-rs, and I therefore, reserve the privile e of resorting to all such legitimate and alterntive embodiments thereof as may be fairly incorporated in the spirit and scope of the invention as claimed.
