Abstract
Abstract A reed switch analyzer for testing the mechanical and electrical characteristics of reed switches employs a unique transport assembly in a test head for advancing the reed switches through various test stations and timer means for synchronizing the operation of the test head with the reed switch manufacturing machine so that the test head is compact and is easily and conveniently added to or removed from the manufacturing machine without interfering with its operation. The test head provides test result signals for separating good switches from the bad ones and for providing feedback information to the machine operator for quality control purposes as the switches are automatically received from the manufacturing machine.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
274 words
A transport assembly for moving reed switches or the like from station to station comprising: a housing having an open channel formed in a horizontal surface thereof with support notches located opposite one another on either side of the channel spaced along the channel, each pair of oppositely placed notches defining a station in which a reed switch is to be received; a carrier bar positioned within the channel which is free to move vertically or horizontally relative thereto, said carrier bar having notches along its length which align with said pairs of support notches while said bar is in a level position relative to the channel surface and in a normal position relative to the channel length; a transport member for moving said bar, including raise means which is activated to raise said bar from the level position so that the undersides of any reed switches received in the notches thereof clear the top of said support notches, lower means which is activated to lower said bar below the level position so that the top surface of the bar clears the undersides of the reed switches received in said support notches and sliding means which is activated to advance said bar horizontally so that each of said bar notches are advanced to the next pair of support notches and is deactivated to return said bar to the normal position, and timing means for controlling said transport assembly in the following cyclical sequence: 1) activate said raise means, 2) activate said sliding means, 3) deactivate said raise means and activate said lower means, 4) deactivate said sliding means and 5) deactivate said lower means.

Claim 3
Dependent Claim
27 words
The transport assembly of claim 1 wherein each of the transport assembly means includes a pneumatic device which is responsive to electrical signals from said timing means.
Claim 4
Dependent Claim
39 words
The transport assembly of claim 2 wherein the generation of electrical signals by said timing means is mechanically controlled by a cam shaft adapted to be synchronized to and driven by a machine used for producing the reed switches.
Claim 5
Dependent Claim
17 words
The transport assembly of claim 2 wherein said pneumatic devices are air cylinders controlled by solenoid valves.
Claim 6
Dependent Claim
33 words
The transport assembly of claim 4 wherein said sliding means includes a slider connected to the piston rod of an air cylinder and a horizontal guide for restricting the slide to horizontal movement.
Claim 7
Dependent Claim
73 words
The transport assembly of claim 5 wherein said transport member includes a horizontal platE situated below said slider and the air cylinder of said lower means is affixed to said slider while its piston rod is affixed to said plate for lowering said plate when activated and said raise means comprises two air cylinders affixed to said plate while their piston rods are affixed to said carrier bar for raising same when activated.
