This invention relates to intermittently operated mechanism for exhibiting apparatus such as advertising or projection devices driven by spring, weight, electric or other power, and to time or speed controlling or controlled mechanism for indicating and recording devices and the like.

The present invention comprises intermittently operated motor driven advertising, in-

dicating or recording apparatus, wherein the apparatus is driven by motor operated mechanism provided with intermittent releasing mechanism operatively connected to any suitable member of an adjacent clock, clock f movement or other speed or time controlled mechanism. The relative direction of movement of both mechanisms is so arranged that any pressure exerted on or through the releasing mechanism upon a connect-ing member ot the controlling mechanism will be in the direction of motion of such connecting member, so that there will be no retardation or braking action on the controlling mechanism.

The intermittently operated mechanism may be driven by its motor through toothed rearing of which any one or more shaft or shafts of the intermittently released mechanism has a crank and a connecting rod cr;- tending from the crank pin to a notched or toothed wheel fixed on a suitable shaft of the clock train or other speed or time controlled mechanism, the notched wheel being?I driven at a slower peripheral speed than the crank pin, the free end of the connecting` i l being provided with a transverse pin or member adapted to be engaged by the teeth or the like of the notched wheel and hold or d the crank until the notched wheel has moved sufficiently to allow the crank to turn over dead centre and enable the motor to rotate the crank so that it will perform the return movement or a series of such movements of the connecting rod necessary to carrj,T its transverse pin into a position in which it will be engaged by an adjacent tooth of the notch.- ed wheel, and the operation is repeated. The connected rod is preferably made slightly extensible and compressible and restorable lav by spring action when the extending or ci pressing force is removed.

The motor driven advertising, indicating or recording devices may be mounted on discs or drums arranged on vertical or hori- Zontal axes, a convenient method being to support them on a disc mounted on a vertical axis running in jewel or other suitable trictionless or practically frictionless bear. or pivot centres, and the devices may be sup'L ported by gravity 0r otherwise in recesses or guides provided in the face of the disc at uniorm distances apart circumferentially. The devices may be transparencies to use in illuminated or projection apparatus.

The movement of the toothed wheefL be controlled by clock escapeinent me anism and the clock train provided with an ordinary clock face provided with hour or minute hands.

A manner of carrying out the invention is illustrated by the accompanying drawings wherein Figure 1 is a front elevation of a clock case containing the device, Figure 2 a section side elevation showing diagrammatically the main elements of the apparatus, Figure 3 a diagram of the intermittently operated mechanism, when using two motors, Figure 8a is a diagram of the intermittent mechanism when using one motor only, Figure a a plan of the same, Figures 5 and 6 alternative details of holders for the transparencies or slides, and Figure 7 is a detail oi the train mechanism.

In these drawings 2 is a casing containing a translucent clock dial 3 and a screen 8 which may be a. sheet of frosted glass, a is a disc on which transparen devices 6 or slides containing the matter to be exhibited are arranged, l a lamp arranged above the transparencies 6 and also behind the translucent clock dial 8. The rays from the lamp l pass through a condenser lens 5 arranged above the transparencies 6, that is at a position under which each of the transparencies 6 will be moved intermittently so that the projected rays will pass downwards on to a reflector 7 inclined in such a manner as to reflect the projected rays on to the screen 8.

The disc a carrying the transparencies 6 is rotated a shatt 9 mounted at each end in adjustable pivot bearings 10 and 11 and carrying a toothed mitre or bevel wheel 12 arranged to mesh with a toothed pinion 13 mounted on a shaft lelcarrying a pinion and a crank 16.

ln order to allow tor the taking up of play between the parts, the toothed pinion 13 is not fined directly to the sha t 1st but connected thereto by means ort a spring 13a ot which one end is fastened to the wheel 13 and the other to collar 13 fixed on the shaft 14 and through which power is transmitted. Such means tor taking up the play may7 however, be arranged at any other suitable portion ot the gearing.

rlhe disc carrying the transparencies 6 when arrested at each periodic movement is retained by pawl #l5 pivoted to a support member 49, the tree end of the pawl being arranged to engage with a notch or groove 16 provided ir the tace ot the disc a.7 the number oit notch piuwided in the disc correspending` to the number of transparencies 6. The pinion 15 forms the last wheel et a train of toothed gears 1r, 16, 197 20, 21, 23 ot which 23 is dir/en by a spring 24 in a manner similar to a clockj thereby comprising a motor driving` the disc a, containing the transparencies 6 or slides containing 'the matter to be exhibited d also driving a crank 16 which is connected by a connecting rod 25 to releasing mechanism comprising a second train ot wheels. Any suitable governor such as an air vane or ily wheel 9a` ma;Y be provided on this tiret mentioned train of wheels.

The second train oi wheels in the example shown is driven by a spring 27 in a manner similar to the tirst trein described above. The spring Q? drives through a train of toothed gears Q8. S29, 30. 31. 32 and 33, a notched r toothed wheel 3l. and on the shaft 35 carrying the toothed wheel 3% also a toothed wheel 36 `gearing with a pinion 37' on a shaft 38 carrying an escapement wheel 39 with which cto-operates an escapement l0 controlled by a pendulum 41 in the usual manner. rllhe toothed wheel ot the time controlled train. gears with a wheel L14 driving the train of the hands 3a, 3l) ot the clock dial 3.

The two trains ot wheels are carried Vin bearings in front and rear pla- tes 42 and 43 as in ordinary clock work actions.

The driving` powers ot the two springs 24.- and 27 are approximately ot equal strength. and the trains are so designed that the notched or toothed wheel 34 makes one revolution in about the same time that the crank 16 makes twenty revolutions, and the wheel 34 contains nine notches in its periph-er. The crank 16 and the notched or ratchet wheel 3d form interconnecting transmission members connected together by the connecting rod 25.

The shaft 14 carrying the crank 16 is approximately at the same level as the shaft ot the notched wheel 34, and the connecting r'od .25 extends to the wheel 34 and has at its free end a 'forked portion carrying a transve member or pin which engages the notches on the upper portion ot the notched wheel 34.

The function of the connecting rod 25 is to arrest or delay the motion of the crank 16 at or during a `predetermined period corresponding to the desired pe iod of projection ot the transparencies 6 and corresponding to the timing by the clock train. To eli'lect this function ot the crank 16 and notched wheel 3ft are arranged to rotate in the same dircction, and the crank 16 arranged to impart a pull on the connecting rod :25 during the half revolution when the crank 16 is uppermost, that is to say above the shaft 14, and its direction ot motion is away from the notched wheel 3st of which the upper notches are turning slowly towards the crank 16. The pin ot the connecting rod is held by one of the notches in the wheel 3-1 while approaching the crank 16 and until the crank 16 reaches the position furthest from the notched wheel 34, whereupon the crank 16 continues to turn without any restraintdownwards an d backwards beneath its shaft 1A by the action of the spring 2st, and thc connecting rod is similarly driven back until the connecting rod pin is immediately disengaged trom the notch in the wheel 3l and slips back into the next notch at or before the instant when the crank has completed the halt turn below its shaft. The crank 6 then contnue-s to turn above its shaft until its rotation arrested or delayed by the pin dropping by gravity and engaging the bottom ot the notch it has just entered, when the action is repeated.

In order to provide a movement ot the disc or slide holder equivalent to one complete revolution of the crank 16 the teeth ot the mitre wheels 12 and 13 operating the slide holder a may be constructed with tree play tor instance between the faces ot the teeth ot the wheels 12 and 13, so as to allow the slide holder to continue to revolve by its own momentum after each periodic arrest ol' the dgiving mechanism until such play is taken up and the slide holder fr is engaged and held by the pawl 45 droppingr into the groove 46 as described. Upon the motion of the disc holder a being arrested by the takingr up ot the play between the parts or by the action ot an interposed spring it may be held by a suitable ratchet device from any tendency to recoil.

The throw of the crank 16 is arranged to bc greater than the distance between the bottoms oit consecutive notches in the wheel 34 for the purpose of ensuring the free move- (ifi ment of the pin from one notch to the next and to allow the crank 16 to run well forward towards the extremity of its travel before it is arrested or delayed by the engagement of the pin 35 in the next notch cf the wheel 34 as described.

In order to allow of an increase in the ferward movement of the connecting rod 25 and also to protect the train of the notched wheel 34 from shock the connecting rod 25 may be made of a light strip of metal or other suit-- able material and bent or waved as at 23a or otherwise made extensible and contractabie, and thereby allow of an extension in its length when arrested by the notches in the wheel 34 and so accommodate pull or momentum of the train driving it.

In a modification of the apparatus the spring 27 and toothed wheels 2S and 29 are dispensed with and the wheel 30 driven from the wheel 22 by means of intermediate wheels 4:7 and 470 of equal size shown in Figure 3 in dotted lines. In this modification the wheel 47 is free on the shaft 47a and is connected to the wheel 470 by a power m i sur ing spring 47?) as shown in Figure 7. rlhe shaft 47a is driven by the fixed wheel 470 from the wheel 22 and transmits the power through the spring 475 and the wheel 47 to the wheel 30 of the clock train. The intermediate wheels 47 and 470 may be substituted by any other suitable transmission mechanism.

The transparencies 6 are held by gravit-v in angle pieces 48 arranged to form corner pieces extending from the disc a at equal distances from openings t2 provided for the projection rays. Instead of the angle pieces i8 the transparencies may be arranged to fit in slides 50 (see Figure 6) fastened over the openings a2 by screws or rivets passing through the holes 51, the openings a2 being made rectangular to correspond to the rectangular opening 53 provided in the slides 50. Figure 5 illustrates a slide for holding charts or other devices for use with apparatus not constructed for projecting transparencies.

The motor operated mechanism may be arranged to drive switching devices for electrical circuits, or relay mechanism.

The power expended by the crank driving` train may be employed to impart impulses, or control impulses given, to any desired mechanism for any desired purposes, by direct mechanical action or interposition of parts. electric contacts and similar means.

A device of this character is illustrated by Figure et wherein the disc a is of metal and is provided. with a number of circumferentially spaced blocks a3 on which bears an electric contact brush a4, the brush a4 being connected to one lead a5 of an `electric supply circuit, while the other lead a6 of the electric supply circuit is connected to the disc a through the shaft 9.

Further the delay or arrest of the crank 16 may be effected upon its passage beneath its shaft instead of above it as shown in IV igure 3, and the pin 35 at the forked end of the connecting rod 25 in such case may press against the notches on the under portion of the notched wheel 34e, which are moving away from the crank 16.
