Yale 101-1/2 comb lock

[Doug MacQueen]

When changing the comb, the outer wheel sections are moved out of engagement from the inner wheel. This is accomplished with a simple turn of the key, but the design of the parts to pull this off is not so simple. A cage surrounding the wheels is center hung similar to the door and crane hinge of the cannonball. This allows for a straight albeit slight in and out movement of the wheel cage as the key is rotated.

I almost never use Google for patent searches unless it's something the US patent office can't do (such as search older patents by inventor name), or I'm not looking for a US patent.

In this case Google Patents (http://patents.google.com), given 1066629 as the search term, comes up with foreign patent GB1066629A which is for a loading apparatus for a lorry. It does, however, prompt you with other possibilities including US1066629A which is the one in question. Of course the US patent office comes up with the patent of interest given that number.

Is that the difficulty you were having?
