Abstract
Abstract An indicator and switching arrangement for programming events to be carried out by an automatic machine or the like. A plurality of coaxially aligned indicator drums having numerals positioned about the outer periphery of each drum are operatively connected to a similar number of coaxially aligned rotary selector knobs. The indicator drums are arranged to present a decimal count in a right reading order within a viewing window. In order to minimize operator confusion, each selector knob is arranged in the same sequential order as the indicator drum that it controls.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
180 words
A selector apparatus for programming an automatic device comprising; a shaft mounted for rotation; a first rotary selector mounted to said shaft; a second rotary selector rotatably supported about said shaft, said first and second rotary selectors being axially aligned along said shaft in a given sequence; a first number indicator drum spaced from said rotary selectors, and mounted to said shaft, said first drum being connected to said first selector; a second number indicator drum spaced from said rotary selectors, and rotatably supported about said shaft; motion imparting means connecting said second rotary selector to said second drum, said motion imparting means including a hollow member connected to said second selector and means spaning said first drum for connecting said hollow member to said second drum, said first and second drums respectively being axially aligned along said shaft in said same given sequence as said rotary selectors, for presenting a pre-selected count at a viewing station; switching means operatively assoicated with each of said drums for generating an electrical signal indicative of a number presented within the viewing station.
Claim 2
Dependent Claim
180 words
A selector apparatus for programming an automatic device comprising; a shaft mounted for rotation; a first rotary selector mounted to said shaft; a second rotary selector rotatably supported about said shaft, said first and second rotary selectors being axially aligned along said shaft in a given sequence; a first number indicator drum spaced from said rotary selectors, and mounted to said shaft, said first drum being connected to said first selector; a second number indicator drum spaced from said rotary selectors, and rotatably supported about said shaft; motion imparting means connecting said second rotary selector to said second drum, said motion imparting means including a hollow member connected to said second selector and means spaning said first drum for connecting said hollow member to said second drum, said first and second drums respectively being axially aligned along said shaft in said same given sequence as said rotary selectors, for presenting a pre-selected count at a viewing station; switching means operatively assoicated with each of said drums for generating an electrical signal indicative of a number presented within the viewing station.
Claim 3
Dependent Claim
30 words
The apparatus of claim 1 wherein said switching means is arranged to send a binary coded signal to the automatic device indicative of the count selected in the viewing station.
Claim 4
Dependent Claim
19 words

Claim 8
Dependent Claim
38 words
An apparatus as in claim 1 wherein one of said drums comprises a units number wheel and the other of said drums comprises a tens number wheel, for presenting a right reading decimal number within the viewing station.
Claim 9
Dependent Claim
24 words
The apparatus of claim 7 having detent means for locating and holding each selected decimal number in a stationary condition within the viewing station.
Claim 10
Dependent Claim
25 words
