Unknown wooden mechanical mantle clock - ID help please

[Antikythera]

This is an older wooden case mantle clock, that has a brass mechanism.

It came with a winding key that is marked as ''waterbury usa" but the case does not look like any waterbury models that I have noted.

The only markings that I have noted on the entire clock are on the upper part of the retaining ring surrounding the clock face.

It looks like its stamped 'PATMAD' and then some sort of number or lettering that is indistinct is present next to that, which appears stenciled by hand.  It may be a number "50", but i cant be sure.

The pendulum is fairly distinctive, and has a silver center portion.  The chime works, and both actions wind up, however the pendulum quits swinging after about 5 minutes, and i assume the action driving the pendulum may be jammed.

If anyone could point me in the right direction as far as model / manufacturer/ year or any other assistance, I would appreciate any advice.

Hi and welcome.

Any chance of a photo of the mechanism, that should be of great help.

One reason you might not find it in a waterbury catalogue is many were custom made. Is there a label inside if so we need a photo of that because depending on the label will tell us what the date is also a number will help.

Probably an Ansonia movement , both pics of the movement and the label as mentioned please.

I removed the mechanism from the clock and took these pics.  It does not appear to me to have a single marking or identifier visible anywhere on it.

Both springs seem to be intact, but only the system driving the chime function actually works.

The pendulum drive winds up to full tension, but stops working after about 5 minutes of swinging, with no gear movement.  This came out of an old Kansas Farm house so guess I can roughly gauge its general age range, but any specifics would be appreciated. 

Thanks in advance.

No labels of any sort found, or even any residue suggesting that a label ever existed on any of the wood case.  I think I identified a sister clock -

This uses a different glass stencil, and the mechanism has the same right angle corners as the action in my clock.  It is being attributed as 1890's which fits the general time frame it was in-situ.

Given that what I have read indicates that Waterbury actions would have rounded corners -

was there some point at which they sourced actions from some outside supplier or changed their product design?

Looks like an American shelf clock movement  used by Chauncey & Jerome and others, mass produced ,also known as kitchen clocks.  I have two steeple clocks with the same movement and a gingerbread clock. American made and exported to the UK mine date from the late 1800s
