Wall clock problem revisited.

I had asked the question in an earlier post as to why my Sessions wall clock might be gaining so much time no matter how I set the pendulum. I also mentioned a skipping sound when the clock was fully wound. I waited for the clock to run down and stop, removed the hands and face to expose the works. I released the click stop on the main spring and guardedly released the remaining tension on the main spring. Used a Qtip with a light machine oil and ran the surface of the spring to remove any surface crud, surprisingly clean. I rewound the clock and did the best I could to center the Tic-Tock and low and behold no skip. After about a half hour I replaced the hour hand and set it to my watch to see how the rate was. Remember the thing was gaining thirty min in three hours before I removed the face and now it is twenty min. slow after five hours. I did see that the escape wheel did jump ahead when I set the hands with the pendulum working and that was the sound I was hearing when the clock was gaining so much time. I included a photo of the works for clarity. I have left the clock running now for twenty-four hours and it has been consistent with the loss of time and have not heard any of the "skipping" I did before. The clock is not stright but it is running consistantly. What should I do now? Does the pallet need to be adjusted or replaced? Should I just leave the clock body at the angle it likes and live with it? The pendelum only swings 5/8ths of an inch, not joking.
Any help and/or advice would be truly appreciated, Frank.

Needs a clean and oil and you need to look at the tutorial about putting in beat.

Move the verge closer to the escape wheel. Move it to where it locks up and will not tick, then back it off until it barely escapes the wheel. Be careful not to break the pallet pin. Sometimes it can be moved with needle nosed pliers and sometimes I have luck using a flat blade screwdriver to pry it. The rivet is usually very tight.

As Kevin suggests, once you get the verge adjusted, you can set the beat by bending the crutch wire. You should be able to get it set in beat so that the case is level.

Also looks like it needs to be fully wound.

Your first post suggests that you tried to slow the clock down by adjusting the pendulum as much as possible? Perhaps the bob is still set too low for the clock to run on time?

Thank you for the responses. Where would I find the tutorial about putting in beat?
thank you again, Frank.

Your clock needs some repair work. It is very dirty and that escape-wheel appears to be in sad condition. Time to seek out a good clock repair person.

I totally agree with Willie. First I can see some serious damage to part of the
escapement wheel. It should be replaced.
The main wheel is dripping with oil. The gears should be totally dry, only the
pivots and bushings should be oiled.
Your clock has an interesting calendar drive that I've not not seen before.
Does your dial have the calendar still?

It has a date hand and here is a photo of the clock with its face. I would like to get the clock serviced here so I will have to check around and try to find a repair person I can trust. The clock hung in my childhood home for years so it is important to me. I would rather have it hang not running than have it butchered up. I have only been living here for about a two years so I have not been in contact with enough with people to have a fix on someone I can trust but I will start my search tomorrow.
Thank you all again for your help. Be safe, Frank.

It is a nice looking clock. As has been mentioned before, you should
try to contact a NAWCC chapter near you. They often have good recommendations.
Do note that even though your clock has the words Regulator on the dial,
it is a open spring movement with a recoil escapement. These will
typically run fast at the beginning of the wind and slow towards the
end. You should expect it to gain about 1-2 minutes a day at the
beginning and loose 1-2 minutes a day at the end, of the wind.
It is a very nice clock and still worth being repaired. I just hope
you don't expect it to perform like a fine regulator.
It is said that if it has to say Regulator, it likely isn't.
I am a fan of calendar dial.

I agree with what others have said. The 'skipping' of the pallets over the escape wheel has really wrecked the teeth of the EW. That could be due to improper adjustment of the pallets but could also be caused or made worse by a worn pivot hole at the escape wheel, and of course the more it 'skips' the more damage to the teeth and that makes it skip even more. I would not run the clock until it is repaired. This is a simple clock movement to repair and generally a pretty good time keeper. Mine has a pendulum swing over 3" after 8 days run. On these Sessions movements be sure to check the click rivet as these often come loose. If you are comfortable with setting the 'beat' and reinstalling the movement you could send the movement out for service if you can't find a local service person.

Again, thank you all for this great information.
I will let it run down while I look into a repair service.
Be safe all, Frank.
