switch machines

[Anonymous]

I recently aquired 3  "right-of-way" slow acting switch machines. they did not come with instructions so I have no idea how to connect them. there is a tab sticking out with 8 electrical connection points. inside is a series of gears that move the arm which has contacts like a post war E unit that slide over the board with the 8 connections. I looked on the internet but couldn't find anything about these machines or the company. the label only says "right-of-way industries, po box 13036, akron ohio". has anybody seen or used these. a copy of the instructions would be greatly appreciated.

This sounds like it might be similar to the Tortoise stall-motor switch machine by Circuitron:

The Tortoise also has 8 terminals.  Two of them are the DC motor.  The other six are a DPDT switch.  If the Right-of-Way is the same, you'll have to sort out which terminal is which by trial and error; but knowing what might be in there may be a help.

I just found this picture of a Right-of-Way switch machine on Ebay.  Except for the lack of a  label, it looks identical to a Tortoise:

Here are the connections for a Tortoise, numbered left-to-right as shown in the Right-of-Way picture:

1, 8  Motor

2, 3, 4  One SPDT switch, with 4 as the common

5, 6, 7  Other SPDT switch, with 5 as the common

thanks Bob, that is it exactly. from your first pic shown on the layout I don't see how to make it operate the ross switches I have. looks like the rod pivots on that adjustable bracket. I will try to get some info on the Circuitron unit as it looks the same.

That's how it works.  You adjust the bracket up or down to give the desired throw.  And the flexible rod provides overtravel to push the points against the stock rails.  The flexible rod does not need to be centered under the track; it can be off to one side (under the table) and push a throw rod, much like a prototype switch machine.

again thanks Bob, I found the install and wiring diagram on the CIRCUITRON website.

Could you post a link?  I've never been able to find a site for them.
