Abstract
Abstract Fixed housing contains a cam and rotatably supports a display shaft carrier. A motor rotates the shaft carrier, and a cam follower on each shaft oscillationally rotates each shaft on its own axis as the shaft carrier rotates on the housing axis. Displays are mounted on each shaft so that the displays rotate on the housing axis and oscillate on the shaft axis. In the preferred embodiment, the housing is mounted over a crib, and the motor for driving the shaft carrier is mountable on the side of the crib.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
142 words
A motorized mobile comprising: a body, means for supporting said body, first and second cam surfaces within said body; a carrier rotatably mounted on said body for rotation about a first axis, means connected to said carrier for rotating said carrier with respect to said body on said first axis; a display shaft rotatably mounted in said carrier for oscillatory rotation about a display shaft axis which is positioned at an angle with respect to said first axis, a cam follower on said display shaft, said cam follower being in engagement with said first and second cam surfaces so that oscillatory rotation of said display shaft about its axis is controlled by said cam faces as said carrier rotates within said body, means confining the movement of said display shaft, relative to said carrier, to oscillatory rotation about said display shaft axis.
Claim 2
Dependent Claim
142 words
A motorized mobile comprising: a body, means for supporting said body, first and second cam surfaces within said body; a carrier rotatably mounted on said body for rotation about a first axis, means connected to said carrier for rotating said carrier with respect to said body on said first axis; a display shaft rotatably mounted in said carrier for oscillatory rotation about a display shaft axis which is positioned at an angle with respect to said first axis, a cam follower on said display shaft, said cam follower being in engagement with said first and second cam surfaces so that oscillatory rotation of said display shaft about its axis is controlled by said cam faces as said carrier rotates within said body, means confining the movement of said display shaft, relative to said carrier, to oscillatory rotation about said display shaft axis.
Claim 3
Dependent Claim
26 words
The motorized mobile of claim 1 wherein: said cam faces face each other and said cam follower has follower fingers which face away from each other.
Claim 4
Dependent Claim
26 words
The motorized mobile of claim 2 wherein: said first and second cam faces have corresponding contours so that said cam follower is substantially under positive constraint.
Claim 5
Dependent Claim
42 words
The motorized mobile of claim 1 wherein: said body includes a main part and a closure plate secured thereto, said closure plate carrying one of said cam surfaces and the main part of said body carrying the other of said cam surfaces.
Claim 6
Dependent Claim
69 words
The motorized mobile of claim 4 wherein: The main part of said body has a central shaft extending therefrom and extending through the center of said body to define said axis of rotation, said shaft being fixed to the main part of said body and said closure plate being irrotatably fixed to said shaft so that said first and second cam surfaces are irrotative with respect to each other.
Claim 7
Dependent Claim
57 words
The motorized mobile of claim 5 wherein: said carrier has angular openings therethrough for rotatable receipt of said display shafts, said display shafts each having a head thereon, and said carrier having a stop therein engaged by said head to axially limit the motion of said display shafts in a first direction with respect to said carrier.
Claim 8
Dependent Claim
41 words
The motorized moBile of claim 6 wherein: said carrier has a cap secured thereto, said cap having a stop surface for engagement over the head on said display shaft to limit axial motion of said display shaft in a second direction.
Claim 9
Dependent Claim
69 words
The motorized mobile of claim 7 wherein: said drive means includes a separate motive housing for containing motor means for motivating said mobile, mounting means on said motive housing for mounting said motive housing, a tube extending from said motive housing to said body to support said body, and a flexible shaft within said tube to convey power from said motive housing to rotate said carrier in said body.
Claim 10
Dependent Claim
69 words
The motorized mobile of claim 1 wherein: said drive means includes a separate motive housing for containing motor means for motivating said mobile, mounting means on said motive housing for mounting said motive housing, a tube extending from said motive housing to said body to support said body, and a flexible shaft within said tube to convey power from said motive housing to rotate said carrier in said body.
Claim 11
Dependent Claim
32 words
The motorized mobile of claim 9 wherein: a gear on said flexible shaft engages with a gear on said carrier so that rotation of said flexible shaft causes rotation of said carrier.
