NATHAN WEIL, OF CHAUX-DE-FONDS, SWITZERLAND.

ADVERTISING-CLOCK.

Application filed May 21 To all 107mmz't may concern:

Be it known that I, NATHAN VVEIL, manufacturer, a citizen of the French Republic, and resident, of Ghauzcde-Fonds, Switzen land, have invented new and useful Improvements in and Relating to Advertising- Clocks, of which the following is a full, clear, and exact specification.

T he' present invention relates to advertis ing clocks -of the kind comprising hinged plates which are adapted'to fall periodically, each plate bearing a numeral constiwith current impulses of an electric clock,

in such a manner that at suitable intervals of time, for instance every minute, the arbor corresponding to one of the two series of plates undergoes an angular displacement, such that one of the plates of its appropriate series is permitted to escape from a' fixed stop and'falls into a vertical position, while after a multiple of such intervals of time have elapsed, for instance every hour, the shaft corresponding to the other series of plates undergoes asimilar angular displacement, thus permitting the next successive plate of the other series to escape from its corresponding stop and fall into a vertical position. i

The invention is illustrated in the accompanying drawings of which Figure 1 is a view in front elevation of one form of advertising clock embodying the invention, a portion of the controlling mechanism for the plates being indicated diagrammatically. Fig. 2 is a view insectional elevation on theline AB of Fig. 1

showing on an enlarged scale one portion of the controlling mechanism of the hour plates. Fig. 3 is a view 1n sectional elevation on the line C-D of Fig. 1 showing on an enlarged scale a portion of the control-J,

ling mechanism of the minute plates.

Referring now to the drawings, the advertising clock comprises two seriesof mov-- able plates a a a below the plates bearing the numerals Specification of Letters Patent. Patented June 10, 191 3 1912' Serial No. 698,710.

7/ 5 which are each pivotally mounted between two disks 0 c and (Z d which are mounted on arbors carried in vertical brackets c e and f f attached to a base 9. Each .of the plates is as shown capable of freely rotating upon pivots near the edges of the disks r c and (Z al The series of hour plates a a a comprises twelve plates bearing on one face (see Fig. 1) the numerals 1, 2, 3 corresponding to the hours, while the series of minute plates Z2 6 b comprises sixty plates bearing the numerals 1 to 60 corresponding to the minutes in one hour. The opposite face of each of the plates of the two series is provided withan advertisement as indicated for example on the plates 9 7,

and 25', in Fig. 1.

Under the action of gravitytlieplates attached to the lower portion of each of the disks occupy a vertical position, whileithe plates at the upper portion of the disks are spread outlike a fan as shown in Figs. 2 and 3. The brackets e and f are provided ith a common support h having a cross piece at the top arranged in such a man-" ner as to retaln the plates a a and b b .in an inclined position ready to rotate .on their pivots and fall into, a vertical positio n. A lateral View of the cross piece 1? is shown in Fig. 2 only.

With the arrangement of the plates on the disks 0 c and d 01. above described it will be understood that the plates as they rotate display successively the advertisement, on

one of the faces of a plate and at the same time the time indication corresponding to the next successive plate.

The plates are displaced at equal intervals of time under the action of an electromagnetic device which is operated by the impulses of current from an electric clock. The electromagnetic device comprises a powerful electromagnet is having an armature m controlled hy a spring Z and connected in the circuit of a suitable battery 12, the circuit of the electromagnet being arranged to be closed at intervals of one minute by the contact-making device of an electric clock 0. The movement of this armature m due to the current impulses is transmitted to the sup- "porting disksof'the plates by a rod 79 connected'to the rocking levers r and 8 (see Figs. 2 and 3) one of whichcontrols the hour'plates and thev other the minute plates.

plates (see-Fig.2) comprises a. ratchet wheel 26 having sixty teeth ada )ted torotate on the same pivot as the rocking lever rv which is provided with a spring controlledlpawl utor operating the ratchet wheel. The latter is provided with aca-m or snail o'which is engaged by one end of a leveiflwi loosely mounted on the arbor at or the disks 0 and 0 The lever w is provided with a spring controlled pawl g adapted to engage with the teeth of a-ratehet wheel 2: having twelve teethand secured rigidly on the arbor '02. Another spring-cdntrolled pawl 'Z mounted on the bracket e is provided for preventing the backward movement or" the ratchet wheel and of the disks as the plates fall into position. Backward movement oithe ratchet wheel 6 is also prevented by a pawl 2 carried by the lever r.

The operation of this form of clock is as follows: At each movement of the armature an, of the electromagnet 70 the rod 72 acting .uponthe lever r rotates the ratchetwheel t by one tooth. The cam or snail i moving with the ratchet wheel 6 displaces the lever w until the latter falls into the notch in the cam so as to take up the position indicated in the dotted lines at 0 .The rapid movement of the lever '10 thus efiected serves to rotate the ratchet wheel a by one tooth carrying with it the disks and plates. This angular movement takes place once in each rotation of the ratchet wheel a, that is once in every hour. The cross piece 2' is arranged in such a manner that at each movement of the disk it allows one plate to fall',, which rotating on its pivots assumes a vertical p0 sition displaying the advertisement on that, face of the plate which is opposite to the.

one bearing the time indication. The opera tion above described is repeated at each hour, the minute plates (see Fig. 3) being similarly actuated every minute by the rocking lever s with its pawl 3 engaging on the teeth of a ratchet wheel 4 having sixty teeth, the

i ratchet wheel a being rigidly secured to the arbor 5 of the disks d d. A pawl 6 pivoted on the bracket f prevents any backward movement of the disks and the ratchet wheel 4 as the plates fall into position. The posi tion of the cross piece 2' relative to the minute plates is such as to permit one plate to be released for each angular movement of the disks, that is to say at each minute of the hour. The advertising clock above described thus indicates the time to approximately one minute, theniinute plates changing their indication each minute and the hour plates every hour. v

The constructional details above described meager/7 the scope of the invention.

What I claim is 1; In. an advertising clock of the kind deserles of plates pivotally connected with two tical plane and bearing each on one face a also on the opposite face an advertisement, and of stops to allow one of the plates of each series tobe-released and to fall at pre determined intervals of time, with two ratchet Wheels and two rocking levers provided withspring-controlled pawlsfor operating said "ratchet wheels and controlled bya common electromagnetic device in accordance with the impulses of current of an 7 electric clock, one of the said ratchet wheels being arranged on one of the said arbors, while the second ratchet wheel bears a snail engaged by one end of a. lever loosely mountedon the second of the said arbors and provided with a spring controlled pawl adapted to engage with the teeth of a-third ratchet wheel rigidly mounted on the said second arbor, substantially as described.

. 2.. In an advertising clock of the kind described, the co'mbination of two separate vertiseinents on that of their faces which is opposite to the one bearing the time indication and pivotally connected with two horizontal arbors arranged in the same vertical plane, of a stop to allow one of the hour plates and to be released and to fall after each hour and of a stop to allow one of the minute plates and to be.released and to fall after each minute, with two ratchet wheels and two rocking levers provided with springcontrolled pawls for operating said ratchet wheels and controlled by a common electromagnetic device in accordance with the imthe said ratchet wheels being arranged on one of the said arbors, while the said ratchet wheel bears a snail engaged by one end of a lever loosely mounted on the second of the said arbors and provided with a sprin -conteeth of a third ratchetwheel rigidly mountdescribed. v

In witness whereof I have hereunto signed my name this 9th day of April, 1912, in the presence of two subscribing witnesses.
