Can anyone tell me why the little piece of linen seen just to the right of the balance wheel would have been put there. It was sandwiched between the plates.
This is a Riverside Ser. No. 6557035

This has been done to increase the end float Mike, I have seen it done with balance cocks as well, another quick fix by some so called repairers.

No.2

Thanks Bill, I thought that may be the case.
Any Idea what the correct method of increasing the end float should be.

I re-sized your pictures for you, Mike.

Let's say you're a watchmaker in a rural area many years before the internet or even the telephone, and a customer brings in this watch. It has a busted balance staff, clearly from a drop, and perhaps a cracked jewel or two.

As you check your spare parts you realize you don't have the correct staff or the necessary jewels, nor do you have the means to fabricate a replacement staff. What do you do?

You would probably use a staff that was as close as you could get it, or you used a staff that would be dictated by the hole jewels that you did have in stock. If the endshake was too much or too little, and you didn't want to scar the plates by punching dimples to add metal, you would add a thin shim on either side of the balance cock screw to adjust the amount of freeplay.

And if the customer wasn't overly choosy, and since this is a gilt movement and not a Maximus, you would time the watch, get payment from the customer (who was probably happy just to see it running again), and call it a day.

As Eric stated - I would rather have a dial washer or piece of paper as a shim under the balance arm, if the other option is someone bending the balance arm or driving a screwdriver tip into the movement plate... Grrrrr!!!!!!!!!!!

Thanks for your opinions. Much appreciated and thank you Eric. I'm still getting the hang of manipulating pictures.

I must admit I have done it. My carry watch, which runs right on the money has a dial washer under the balance bridge. I cut the washer in half and you can stick it under the front or rear of the bridge. I will side with Eric. He has evidently run into this before.Thats how they did it in the old days. They used what they had, could make or if it worked they used it. What we call Mickey Mouse may have been the sign of a good watch maker 50 years ago.

Aloha I had posted this before however I figure it could do with another read
My Watch
Author: Mark Twain


My beautiful new watch had run eighteen months without losing or gaining, and without breaking any part of its machinery or stopping. I had come to believe it infallible in its judgments about the time of day, and to consider its constitution and its anatomy imperishable. But at last, one night, I let it run down. I grieved about it as if it were a recognized messenger and forerunner of calamity. But by and by I cheered up, set the watch by guess, and commanded my bodings and superstitions to depart. Next day I stepped into the chief jeweler's to set it by the exact time, and the head of the establishment took it out of my hand and proceeded to set it for me. Then he said, "She is four minutes slow-regulator wants pushing up." I tried to stop him--tried to make him understand that the watch kept perfect time. But no; all this human cabbage could see was that the watch was four minutes slow, and the regulator must be pushed up a little; and so, while I danced around him in anguish, and implored him to let the watch alone, he calmly and cruelly did the shameful deed. My watch began to gain. It gained faster and faster day by day. Within the week it sickened to a raging fever, and its pulse went up to a hundred and fifty in the shade. At the end of two months it had left all the timepieces of the town far in the rear, and was a fraction over thirteen days ahead of the almanac. It was away into November enjoying the snow, while the October leaves were still turning. It hurried up house rent, bills payable, and such things, in such a ruinous way that I could not abide it. I took it to the watchmaker to be regulated. He asked me if I had ever had it repaired. I said no, it had never needed any repairing. He looked a look of vicious happiness and eagerly pried the watch open, and then put a small dice-box into his eye and peered into its machinery. He said it wanted cleaning and oiling, besides regulating--come in a week. After being cleaned and oiled, and regulated, my watch slowed down to that degree that it ticked like a tolling bell. I began to be left by trains, I failed all appointments, I got to missing my dinner; my watch strung out three days' grace to four and let me go to protest; I gradually drifted back into yesterday, then day before, then into last week, and by and by the comprehension came upon me that all solitary and alone I was lingering along in week before last, and the world was out of sight. I seemed to detect in myself a sort of sneaking fellow-feeling for the mummy in the museum, and a desire to swap news with him. I went to a watchmaker again. He took the watch all to pieces while I waited, and then said the barrel was "swelled." He said he could reduce it in three days. After this the watch averaged well, but nothing more. For half a day it would go like the very mischief, and keep up such a barking and wheezing and whooping and sneezing and snorting, that I could not hear myself think for the disturbance; and as long as it held out there was not a watch in the land that stood any chance against it. But the rest of the day it would keep on slowing down and fooling along until all the clocks it had left behind caught up again. So at last, at the end of twenty-four hours, it would trot up to the judges' stand all right and just in time. It would show a fair and square average, and no man could say it had done more or less than its duty. But a correct average is only a mild virtue in a watch, and I took this instrument to another watchmaker. He said the king-bolt was broken. I said I was glad it was nothing more serious. To tell the plain truth, I had no idea what the king-bolt was, but I did not choose to appear ignorant to a stranger. He repaired the king-bolt, but what the watch gained in one way it lost in another. It would run awhile and then stop awhile, and then run awhile again, and so on, using its own discretion about the intervals. And every time it went off it kicked back like a musket. I padded my breast for a few days, but finally took the watch to another watchmaker. He picked it all to pieces, and turned the ruin over and over under his glass; and then he said there appeared to be something the matter with the hair-trigger. He fixed it, and gave it a fresh start. It did well now, except that always at ten minutes to ten the hands would shut together like a pair of scissors, and from that time forth they would travel together. The oldest man in the world could not make head or tail of the time of day by such a watch, and so I went again to have the thing repaired. This person said that the crystal had got bent, and that the mainspring was not straight. He also remarked that part of the works needed half-soling. He made these things all right, and then my timepiece performed unexceptionably, save that now and then, after working along quietly for nearly eight hours, everything inside would let go all of a sudden and begin to buzz like a bee, and the hands would straightway begin to spin round and round so fast that their individuality was lost completely, and they simply seemed a delicate spider's web over the face of the watch. She would reel off the next twenty-four hours in six or seven minutes, and then stop with a bang. I went with a heavy heart to one more watchmaker, and looked on while he took her to pieces. Then I prepared to cross-question him rigidly, for this thing was getting serious. The watch had cost two hundred dollars originally, and I seemed to have paid out two or three thousand for repairs. While I waited and looked on I presently recognized in this watchmaker an old acquaintance--a steamboat engineer of other days, and not a good engineer, either. He examined all the parts carefully, just as the other watchmakers had done, and then delivered his verdict with the same confidence of manner.

He said:

"She makes too much steam-you want to hang the monkey-wrench on the safety-valve!"

I brained him on the spot, and had him buried at my own expense.

My uncle William (now deceased, alas!) used to say that a good horse was, a good horse until it had run away once, and that a good watch was a good watch until the repairers got a chance at it. And he used to wonder what became of all the unsuccessful tinkers, and gunsmiths, and shoemakers, and engineers, and blacksmiths; but nobody could ever tell him.

-THE END-
