Abstract
Abstract A display construction wherein a motor is employed for moving at least portions of the display. The motor is connected to a drive member which continuously rotates relative to a display support. A drive connection between the motor and display support is adapted to be intermittently and automatically removed whereby the display will have intermittent rest periods. The intermittent drive is controlled by means of a cam member which periodically forces a stop member out of contact position relative to the display support whereby the motor will drive the display support until the contact is re-established.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
232 words
In a construction for supporting an intermittently moving display comprising a motor, a display support, and means connecting the motor to the support for imparting movement to the support, said motor including a continuously rotating drive member, the improvement wherein said means for connecting said motor to said support comprise at least two first stop members carried by said support and fixed in position relative thereto, at least one second stop member, means mounting the second stop member adjacent said support, said second stop member being mounted so that it is fixed against movement in the direction of movement of the display support and so that it is free for pivoting movement in a direction perpendicular to the direction of movement of the display support, means carried by the support for pivoting the second stop member back and forth between one poSition in the path of movement of the first stop members to hold the support against movement, and a second position out of said path of movement to permit passage of the first stop members past the second stop member and to thereby result in periodic movement of the support, said means for moving the second stop member comprising a cam located for engaging said second stop member to drive said second stop member from said one position to said second position each time the cam engages the second stop member.
Claim 2
Dependent Claim
232 words
In a construction for supporting an intermittently moving display comprising a motor, a display support, and means connecting the motor to the support for imparting movement to the support, said motor including a continuously rotating drive member, the improvement wherein said means for connecting said motor to said support comprise at least two first stop members carried by said support and fixed in position relative thereto, at least one second stop member, means mounting the second stop member adjacent said support, said second stop member being mounted so that it is fixed against movement in the direction of movement of the display support and so that it is free for pivoting movement in a direction perpendicular to the direction of movement of the display support, means carried by the support for pivoting the second stop member back and forth between one poSition in the path of movement of the first stop members to hold the support against movement, and a second position out of said path of movement to permit passage of the first stop members past the second stop member and to thereby result in periodic movement of the support, said means for moving the second stop member comprising a cam located for engaging said second stop member to drive said second stop member from said one position to said second position each time the cam engages the second stop member.
Claim 3
Dependent Claim
37 words
A construction in accordance with claim 1 wherein said display moves an angular distance corresponding to the spacing between said first stop means each time said cam moves said second stop means away from said one position.
Claim 4
Dependent Claim
41 words
A construction in accordance with claim 1 including friction drive means between said drive member and said support whereby said drive member imparts movement to said support each time said cam moves said second stop means away from said one position.
Claim 5
Dependent Claim
33 words
A construction in accordance with claim 1 wherein said motor comprises an electrically operated motor, a tubular support for said motor, and batteries mounted in said support for supplying power to said motor.
Claim 6
Dependent Claim
51 words
A construction in accordance with claim 4 including a pivoting bracket supporting said motor, pivoting of said bracket away from the operating position of said motor, exposing the batteries for insertion and removal thereof, said motor being automatically brought into operating contact with the batteries upon pivoting to the operating position.
Claim 7
Dependent Claim
78 words
A construction in accordance with claim 1 wherein said drive member and said support comprise flat plates positioned in overlying relationship with friction drive means interposed between the plates, said first stop means comprising pins extending downwardly from the support plate, said second stop means comprising a resiliently mounted arm normally located in the path of movement of said pins, said cam operating to depress said arm to temporarily move the arm out of said path of movement.
Claim 8
Dependent Claim
37 words
A construction in accordance with claim 1 including a second display support, and drive means interposed between said first mentioned support and said second support whereby movement of the first support imparts movement to the second support.
Claim 9
Dependent Claim
34 words
A construction in accordance with claim 7 wherein said drive means between said supports comprise gears operating to rotate the second support in a direction opposite the direction of movement of said first support.
Claim 10
Dependent Claim
38 words
A construction in accordance with claim 7 wherein said drive means between said supports comprise at least one wheel adapted to rotate said second support in a direction opposite the direction of rotation of the first mentioned support.
Claim 11
Dependent Claim
21 words
A construction in accordance with claim 1 wherein the drive member is directly connected to the drive shaft of said motor.
Claim 12
Dependent Claim
44 words
A construction in accordance with claim 1 including a main shaft for supporting said drive member, said motor being offset relative to the position of said main shaft, and means providing a driving connection between the shaft of said motor and said main shaft.
Claim 13
Dependent Claim
46 words
A construction in accordance with claim 11 wherein said main shaft comprises a tubular member, electrical leads extending through said tubular member, and a light attached at the end of said tubular member adjacent said support, said display being located on said support adjacent said light.
Claim 14
Dependent Claim
51 words
A construction in accordance with claim 1 including at least one wheel interposed between said drive member and said support whereby said drive member imparts movement to said wheel which in turn imparts movement to said support each time said cam moves said second stop means away from said one position.
Claim 15
Dependent Claim
78 words
A construction in accordance with claim 13 wherein said drive member and said support comprise flat plates positioned in spaced apart relationship with said wheel interposed between the plates, said first stop means comprising pins extEnding downwardly from the support plate, said second stop means comprising a resiliently mounted arm normally located in the path of movement of said pins, said cam operating to depress said arm to temporarily move the arm out of said path of movement.
