The movement's frame looks like an H with a T enclosing the top |T| The wheels are nicely visible!
The face end of the pallet pinion is held in place by a bent rod curved out from the frame. The opposite end of the pinion inserts into the frame.
On the case back is written 1900 in pencil.
The wood case decoration appears to pressed into the wood.

Before I get this to run, can I use 3-In-One oil in the pinions?

Thank you.

Don't oil pinions or wheels. Oil only the pivot ends where they poke through the movement plate holes. Just a miniscule amount that will surround the pivot and the inside of the bearing hole.

Clock wheels and their mating pinions are designed to roll together in mesh. Any oil will trap dirt and grind away the pinion teeth. Wind-up clock gear trains are step-up ratio and don't want oil on the gear teeth.

Plug-in-the-wall electric clocks are a different case. The gear pinions and wheels have step-down ratios and normally are coated with a thin grease.

I mean just the holes. I thoughthathe pinions were the shafts which turn inside the holes.
I would not oil the gear teeth, but would it be OK to apply a pencil to the teeth to get graphite on them?
Thank you.

Hi Les,good instruction but could you give a little basic "ground school" on the mechanical meaning of Step Up and Step Down Ratios.....
Thanks,
Bruce

Robert, the axels the gears are fitted to are called arbors. The ends that go through the plates are called pivots. The small gears are pinions. The large ones are wheels. Here's a thread that will give you the proper terminology for clocks:
https://mb.nawcc.org/showthread.php?39874-Clock-Parts-Terminology
Adding graphite to the gears is not advisable. They were designed to run best dry and clean. The only gear that gets any oil is the escapewheel, where a very small amount on the teeth of the escapewheel cuts the friction with the anchor. Only the bushings, where the pivots come through the plates, need oil.

Hi Robert,

I think 3-in-1, despite it's general usefulness in many areas, is not good for clocks, as it tends to spread away from where it's put, which is the exact opposite of what's needed here.

Regards,

Graham

Re: Short metal rods fastened to two metal disks!

Thank you, ALL.
Your educating me and advising me is appreciated.

This clock's "pinions" are not gears but short rods between two metal disks! You can see through them!

Robert, I think that you failed to read Harolds reply that he addressed to you. He said "The ends that go through the plates are called pivots. The small gears are pinions. The large ones are wheels."

Your clock's "pinions" ARE gears, just like everybody else's clock's pinions. The metal disks you speak of may be bushes? The pivots are the little rods that turn in the bearing holes or in the bushes.

cheers

Re: Short metal rods fastened to two metal disks!

Sounds more like lantern pinions I think!
Well, that is another new term to me.
But it is a clever description. Does resemble a lantern withe supports extending up from bottom metal disc to the top. TTT
It appears that more effort goes into making these than just stamping out pinion gears.
