Please help me find out more about this clock

I got a mantle clock a year or two back at an antique store. I fell in love with it but I don't know much about it.

It's a mantle clock made by Ansonia Clock company. On the bottom, it has Canterbury No. 2 Ansonia Clock company New York.

It has a key; one slot to wind it one slot on the other side to set it and on the top it has a slot for slow and fast?

Is there a name for this kind of clock? It has a weighted pendulum and from what I can tell the face is painted metal. I was told it was from the early 1900's. But I looked on the back and on the movement it was stamped 4 22. ?

I looked on Google and everywhere else and cannot find any information on it. I'd love to find some info on it because I plan to pass it on to my children. And I really love this clock. Any help is very appreciated. I'm not looking to sell I'd just love some more info on this clock.
