Abstract

Abstract The invention provides a compact device for selecting the numbers to play in a game of chance, such as a lottery game. The device includes a number generator portion comprising a number wheel having a circumferential edge partitioned into segments, each bearing a different numerical indicia from the field of lottery numbers. A motor is connected to the number wheel so that when the motor is activated by a switch, the number wheel rotates about the motor axis. The number wheel and motor are contained in a housing having a window portion aligned so that only one of the numerical indicia of the number wheel is visible through the window at a time. By repetitive activation of the switch, a series of more or less random numbers will thus be generated. The housing can be configured so that it forms a relatively small, cylindrical barrel, suitable for attachment to a similarly-sized accessory portion such as a pen or flashlight.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 193 words
An apparatus for selecting a random number from a specified field of numbers comprising: a disc portion having a circumferential edge, said edge being partitioned into a plurality of segments, each segment bearing a different numerical indicia corresponding to a single given number from said specified field of numbers; drive means for rotating said disc about an axis, said drive means comprising motor and a battery; switch means for activating said drive means; and housing means for containing said disc portion, drive means, and switch means, said housing means having a window portion for displaying only one of said disc portion numerical indicia at a time, said housing means being generally cylindrical in shape, and including a pocket clip portion for removable attachment to a users pocket, said pocket clip portion comprising said switch means, and said housing means including a writing instrument portion which is removable and replaceable with a flashlight portion; wherein when said switch means is closed, said drive means rotates said disc portion within said housing means, and when said switch means is open, said disc portion stops rotating and displays only one numerical indicia through said housing window.
Claim 2
Independent Claim 193 words
An apparatus for selecting a random number from a specified field of numbers comprising: a disc portion having a circumferential edge, said edge being partitioned into a plurality of segments, each segment bearing a different numerical indicia corresponding to a single given number from said specified field of numbers; drive means for rotating said disc about an axis, said drive means comprising motor and a battery; switch means for activating said drive means; and housing means for containing said disc portion, drive means, and switch means, said housing means having a window portion for displaying only one of said disc portion numerical indicia at a time, said housing means being generally cylindrical in shape, and including a pocket clip portion for removable attachment to a users pocket, said pocket clip portion comprising said switch means, and said housing means including a writing instrument portion which is removable and replaceable with a flashlight portion; wherein when said switch means is closed, said drive means rotates said disc portion within said housing means, and when said switch means is open, said disc portion stops rotating and displays only one numerical indicia through said housing window.
Claim 3
Dependent Claim 49 words
