Claim 11

An assembly as recited in claim 9 wherein said housing is of inexpensive fibrous cellulosic material, and wherein said support structure comprises an operatively rigid plate attached to said housing and forming the bottom thereof.

Claim 12

An assembly as recited in claim 1 further comprising means for suspending said housing so that said output shaft from said d.c. motor extends generally downwardly, said suspending means operatively attached to said housing.

Claim 13

An assembly as recited in claim 11 wherein said means for suspending said housing comprises a flange and means defining a plurality of openings in said flange, said flange formed on said housing at an end thereof opposite said support structure, said openings each extending in a dimension generally perpendicular to said d.c. motor output shaft, and said openings spaced apart from each other in another dimension both perpendicular to said d.c. motor output shaft and to the dimension in which said openings extend.

Claim 14

An assembly as recited in claim 1 wherein said means for operatively connecting said second shaft to said d.c. motor output shaft comprise reduction gearing means, said reduction gearing means mounted within said housing.

Claim 15

An assembly as recited in claim 1 in combination with a display, and a flexible band of elastomeric material interconnecting said display and said means associated with a portion of said second shaft for facilitating attachment of a display to said second shaft.

Claim 16

An assembly as recited in claim 14 further comprising electronic circuit means for supplying a timed pulse of electrical energy to said d.c. motor from a substantially constant source of d.c. power.

Claim 17

An assembly as recited in claim 15 wherein said electronic circuitry means is mounted within said housing at a portion thereof remote from said d.c. motor output shaft.

Claim 18

An assembly as recited in claim 16 wherein said electronic circuitry means consists essentially of a FET, a resistor, a capacitor, and a Zener diode.

Claim 19

An assembly as recited in claim 15 further in combination with at least one solar cell providing said d.c. power source.

Claim 20

A power assembly for rotating a hanging display, comprising: a housing; a d.c. motor having an output shaft; means for mounting said d.c. motor within said housing; a support structure operatively stationary with respect to said housing; a second shaft, distinct from said d.c. motor output shaft; means for mounting said second shaft to said support structure for rotation of said second shaft with respect to said support structure so that said second shaft and support structure carry the weight of a display operatively connected thereto; means associated with a portion of said second shaft for facilitating attachment of a display to said second shaft; and means for operatively connecting said second shaft to said d.c. motor output shaft so that rotation of said d.c. motor output shaft effects rotation of said second shaft with respect to said support structure, said connecting means comprising a flexible tubular coupling of elastomeric material having a first end thereof operatively attached to said d.c. motor output shaft, and having a second end thereof operatively attached to said second shaft.

Claim 21

A power assembly for rotating a hanging display, comprising: a housing; a d.c. motor having an output shaft; means for mounting said d.c. motor within said housing; a support structure operatively stationary with respect to said housing; a second shaft, distinct from said d.c. motor output shaft; means for mounting said second shaft to said support structure for rotation of said second shaft with respect to said support structure so that said second shaft and support structure carry the weight of a display operatively connected thereto; means associated with a portion of said second shaft for facilitating attachment of a display to said second shaft; and means for operatively connecting said second shaft to said d.c. motor output shaft so that rotation of said d.c. motor output shaft effects rotation of said second shaft with respect to said support structure, said connecting means comprising a flexible tubular coupling of elastomeric material having a first end thereof operatively attached to said d.c. motor output shaft, and having a second end thereof operatively attached to said second shaft.
