Abstract
Abstract A switchboard having a base with parallel grooves and flat lateral strips spacing the grooves, electrical conductive rods positioned in the grooves, and a contact blade secured to one end of a lever mounted on a programming wheel so that the blade contacts a rod in a groove when the programming wheel bottoms on the opposite sides of a groove. Conductive rails, normal to the conductive rods, can be secured to the switchboard to coact with a contact plate, in electrical contact with the contact blade, which is urged against the rails with a coiled spring coacting between the contact plate and the contact blade.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
157 words
A switchboard comprising a base having evenly spaced grooves with spaced sidewalls and having flat strips spacing said grooves; electrically conductive means positioned in at least one of said grooves between said sidewalls; and an indexing switch mounted on said base having a lever rotatably mounted on a wheel, adapted to roll over the top face of said base on said flat strips spacing said grooves, and a contacting blade secured to said lever at a position adapted to move into contact with electrically conductive means positioned between the sidewalls of a first one of said grooves when said wheel bottoms are between the sidewalls of a second one of said grooves spaced apart from said first one of said grooves and form an electrical contact with said electrically conductive means wherein said contacting blade is lifted away from said conductive means positioned between the sidewalls of said first one of said grooves by rotating said lever.
Claim 2
Dependent Claim
157 words
A switchboard comprising a base having evenly spaced grooves with spaced sidewalls and having flat strips spacing said grooves; electrically conductive means positioned in at least one of said grooves between said sidewalls; and an indexing switch mounted on said base having a lever rotatably mounted on a wheel, adapted to roll over the top face of said base on said flat strips spacing said grooves, and a contacting blade secured to said lever at a position adapted to move into contact with electrically conductive means positioned between the sidewalls of a first one of said grooves when said wheel bottoms are between the sidewalls of a second one of said grooves spaced apart from said first one of said grooves and form an electrical contact with said electrically conductive means wherein said contacting blade is lifted away from said conductive means positioned between the sidewalls of said first one of said grooves by rotating said lever.
Claim 3
Dependent Claim
70 words
The switchboard of claim 1 wherein said lever has a first end, an opposite second end, and a midportion between said first and second ends, and said lever is mounted to said wheel proximate said midportion with said contacting blade secured to said lever proximate said first end wherein said contacting blade is lifted away from electrically conductive means in a groove by depressing the second end of said lever.
Claim 4
Dependent Claim
42 words
The switchboard of claim 2 wherein said sidewalls of said grooves are generally parallel opposing walls and said grooves are recessed into said base a sufficient depth to receive electrically conductive means and provide an indexing chamber above said electrically conductive means.
Claim 5
Dependent Claim
37 words
The switchboard of claim 1 wherein directing means are secured to said base for directing the movement of said indexing switch substantially normal to said lateral strips as said switch rolls on said wheel over said base.
Claim 6
Dependent Claim
70 words
The switchboard of claim 4 wherein said lever has a first end, an opposite second end, and a midportion between said first and second ends, and said lever is mounted to said wheel proximate said midportion with said contacting blade secured to said lever proximate said first end wherein said contacting blade is lifted away from electrically conductive means in a groove by depressing the second end of said lever.
Claim 7
Dependent Claim
42 words
The switchboard of claim 5 wherein said sidewalls of said grooves are generally parallel opposing walls and said grooves are recessed into said base a sufficient depth to receive electrically conductive means and provide an indexing chamber above said electrically conductive means.
Claim 8
Dependent Claim
73 words
The switchboard of claim 6 wherein said directing means comprises an elongated slot, normal to said flat strips spacing said grooves, in a top plate secured to said base spaced apart from said top face, wherein said second end of said lever passes through said slot and is held in a predetermined position as said indexing switch is rolled along said top face of said base over said flat strips spacing said grooves.
Claim 9
Dependent Claim
77 words
The switchboard of claim 1 wherein conductive rail means are secured to said base, spaced above said top face of said base and normal to said flat strips spacing said grooves, and a contacting plate, secured to said indexing switch, and in electrical contact with said Contacting blade, is held in sliding contact with said conductive rail means as said indexing switch rolls over said top face of said base on said flat strips spacing said grooves.
Claim 10
Dependent Claim
70 words
The switchboard of claim 8 wherein said lever has a first end, an opposite second end, and a midportion between said first and second ends, and said lever is mounted to said wheel proximate said midportion with said contacting blade secured to said lever proximate said first end wherein said contacting blade is lifted away from electrically conductive means in a groove by depressing the second end of said lever.
Claim 11
Dependent Claim
45 words
The switchboard of claim 9 wherein biasing means are positioned between said first end of said lever and said contacting plate to urge said contacting plate against said conductive rail means and to urge said contacting blade against an electrically conductive rod in a groove.
Claim 12
Dependent Claim
63 words
The switchboard of claim 10 wherein said electrically conductive rail means comprises a conductive leg positioned on opposite sides of said second end of said lever wherein said second end of said lever is held in a predetermined position by the conductive legs as said indexing switch is rolled along said top face of said base over said flat strips spacing said grooves.
Claim 13
Dependent Claim
37 words
The switchboard of claim 10 wherein directing means are secured to said base for directing the movement of said indexing switch substantially normal to said lateral strips as said switch rolls on said wheel over said base.
Claim 14
Dependent Claim
42 words
The switchboard of claim 12 wherein said sidewalls of said grooves are generally parallel opposing walls and said grooves are recessed into said base a sufficient depth to receive electrically conductive means and provide an indexing chamber above said electrically conductive means.
Claim 15
Dependent Claim
73 words
The switchboard of claim 13 wherein said directing means comprises an elongated slot, normal to said flat strips spacing said grooves, in a top plate secured to said base spaced apart from said top face, wherein said second end of said lever passes through said slot and is held in a predetermined position as said indexing switch is rolled along said top face of said base over said flat strips spacing said grooves.
Claim 16
Dependent Claim
38 words
The switchboard of claim 14 wherein said electrically conductive rail means comprises a conductive leg positioned on opposite sides of said second end of said lever and between said top face of said base and said top plate.
