ELECTRICAL ADVERTISEMENT CLOCK Filed on so. 1951 Patented Sept. 27, 1932 FERDINAND SCHNEIDER, or FULDA, GERMANY ELECTRICAL ADVERTISEMENT CLOCK 7 Application filed October 30, 1931. Serial No. 572,190.
provided a bevel gear wheel which mesheswith another bevel gear wheel supported by 1. the clockwork back plate, a driving pulley being attached to the shaft end of the latter gear wheel, which driving pulley transmits its rotation by means of a cord'or belt to a pulley of a roller carrying the endless advertisement go hand. I
By this means the advertisement band is made to display anew advertisement at predetermined intervals, for example every half hour. The diameter of the driving pulley is chosen with due regard to the magnitude of the advertisements to be displayed, in order to ensure correct positioning of the advertise ments in the field of view.
The subject of the invention is shown in the accompanying drawing. A clockwork mechanism 1, known per se, is adapted to be wound up by an electric motor 2,and is provided with abevel gear wheel 3 positioned outside the frame plate on a shaft of the winding up gearing. The wheel 3 is driven from the motor 2 at a high gear ratio by means of a train of gear wheels.
of which is rotatably mounted'in bracket 6. The bracket 6 is securedby screws 7 to the clockwork back plate. Two positioning rings 8 are mounted on the shaft 5, the said The bevel gear wheel 3 meshes with a second bevel gear wheel 4, the shaft 5 runs an endless advertisement band 16, for the tightening of which a weight-roller 17 is inserted or mounted inside its lower part. When the driving spring is being electrically tensioned or wound up,.the bevel gear wheel 3, connected at a high gear ratio to the electric motor, is rotated, and transmits its rotation to the bevel gear wheel 4 meshing therewith, whereby the rotation of the pulley'lO mounted on the shaft 5 sets in rotation, by means of the cord 11, the pulley 12 together withthe roller I 13, whereby the advertisement band 16, re
quiring to be driven, is displaced. The necessary adhesion between the roller 13 and the band 16 is obtained by mea'ns of the weightroller 17 suspend-ed within the band, the arrangement being such that the advertisements carried by the band are exactly positioned within the frame of the viewing aperture.
What I wish to claim and secure by U. S.
Letters Patent, is
, An electrical advertisement clock of which the clockwork driving agency is tensioned at definite intervals by means of an electric motor,comprising-winding up gearing, a bevel gear wheel mounted on the shaft end of a wheel of the winding up gearing, and a second bevel. gear wheel meshing therewith, a drivingpulley mounted on the shaft for rotation thereby said driving pulley transmitting its rotation by means of a belt to a pulley positioned on a roller carrying the advertisement, band, so that the advertisements on the band are caused to appear at definite intervals, correctly positioned in the field of view.
. In testimony whereof I affix my signature. FERDINAND SCHNEIDER.
rings being adapted to permit easy adjustment of the gear wheel 1 relative to the gear wheel 3. A driving pulley 10 is securedon the end of the shaft 5 projecting laterally beyond the bracket 6. The pulley 10 drives a pulley 12 and thereby a roller 13, by means of a cord 11. The roller 13 is rotatably mounted 50 in bearings 14, 15. Over the roller 13 there
