This was the only website that I could find when Googling "Westinghouse TCS 111". I couldn't even find a similar picutre of this on Google Images. There is a lot of really cool and really informative info here.
I recently inherited a Westinghouse TCS-111 watthour meter from my father.
I am an amateur woodworker and would like to turn this into a lamp of some sort. So that when the lamp is turn on the dials will spin on the front showing the watt power consumption.
My question is, how do I properly connect the wires to the back of the meter?
Here is a picture of the front of the meter:
Here is a picture of the back of the meter (the top of picture is the top of meter):
Do I need to be worried that the watthour meter would be faulty?
I was also wondering if anybody could tell me what the metal "terminal" is for on the left front of the glass housing?
Thank you to anyone that has any info they can share. As I said, this seems to be the only website I could find that has an active community with extensive knowledge.

HI! and welcome to the forum. thats an interesting meter, it always amazes me the different custom designs that show up from time to time. this is based on the CS and it has a Timer built into it aswell, probabally where the TCS comes from.
i am not an expert on these meters but there are several guys out here that know more about classic meters than me, so my reply to you is a starter until one of them can give you more info.
this is a 240v meter, you can apply 120v to the top 2 lugs and supply the lamp with the bottom 2 lugs, power flows in the top and out the bottom. the Timer presents several dynamics, 1. i dont know if it can be disabled, because it will likely interfere with you wanting to turn on the lamp when it says power should be off. this was likely used in some kind of street lighting or sign lighting. and 2. running the timer at 120v would skew its time keeping ability anyway, likely only running at 50% speed or less due to supply with 120V

as for bypassing the timer, i would think its possible, you would need to identify the internal wires that supply the timer motor and then rotate the timert to a position where its contacts are connected in the on position, then remove power to the timer motor, that should keep power passing thru the timer all the time. im not 100% sure of the knob on the front left of the glass, but i suspect its for resetting the timer to correct time incase the power went out or the timer needed to be adjusted for customer request, not sure but thats my thought on it.
Check if the on / off pins are on the timer dial. Turn timer on and then remove the pins. The timer will work but won't switch. and as suggested, disconnect one of the timer motor wires inside the meter. As it is a 60 Hz synchronous motor it may not start up on 120 Volts
The outside knob is for adjusting the timer after a power cut, the meter reader can cut the seal and do the neccessary adjustments.
Many of my meters are turning around on the web.
Have a look on YouTube
Sorry for the late reply. Went on an unplanned vacation (can't complain about that).
Yes, I saw the pins on the timer "disk." My thought was to remove them and the timer would not "turn off" so to speak. I can definitely try disconnecting one of the timer motor wires as well.
I did a quick metering of the four posts on the back of the meter. The top right post does not make continuity to the top left or either of the bottom posts. The top left post makes continuity with the bottom left and bottom right posts.
You stated, "as it is a 60 Hz synchronous motor it may not start up on 120 volts." Does that pose any safety concerns with the meter? Is it okay to power a lamp or something with this?

This looks like a form 4s meter looking at the terminals on the back. If so, the meter is powered up by the two terminals in the middle. The outer 4 terminals are for current and current return. It is hard to tell. What is the amp rating on the meter?
