    A lot of the bells I find are missing the clapper. Reading “That Vanishing Sound” I understand the size and weight of the clapper is in direct relation to the size of the bell. What weight clapper is correct for a 30 inch iron church bell? Is there a chart or means of determining the weight of the clapper for different size bells? Is there a difference in the chart for brass bells or iron bells?

    The clapper for that size bell is 4 inches in diameter in cast iron.

    Thanks, Is there a formula to determine clapper size or weight?

      The formula is: 2.4 times the thickness of the bell mouth.

        I find that by measuring the thickness of the “sound bow” then using your 2.4 multiplier it works out to about the same as the 4 inch. I am not sure if this will work with all large bells but it is a good ballpark figure. Thanks

    None that I know. The No 30 and on had a tip at the bottom of the ball and above the bell had a narrow neck to the steel stem. They weighed more as they go bigger with size of church bell.

    Thanks, Until I find a better clapper, for the 30 incher, I am using half of a 20 pound barbell made of cast iron & lead. By chance it measures 4 in dia.

    Go to Brosamers Bells and have a look at the cast iron bells pics. It shows the clapper and its shape. Also go to Lower Bells site. He has those type of bells and maybe a clapper for the No 30. Our school use to have a no 30 and us kids use to pull the chain that ran down the ceiling of the 1st grade class room. It was a pretty sounding bell indeed. When the school closed I got it for our church. Its now rings every Sunday atop a brick pedestal.

    Thanks, I will try the contacts for the clapper. I have the bell mounted on an “A” frame by my workshop. I am tempted to give her a swing whenever I walk by and quite often do. I love the sound of this bell.

    The No 30 bell has a grand friendly sound. Some of the others larger have a melancholy lonely sound but quite beautiful as well. I never knew how C S Bell made these bells sound that way and I do not think he tuned them that way. Maybe someone in the know can explain how it was done. If you had 2 no 30s beside each other, they would sound very close to the same. Same goes with the other cast iron alloy bells I think they added a metal in the mix called amalgam. It was used to strengthen the iron. If the iron bells especially that size were just cast iron alone none would have survived without being broken or cracked.

      The CS Bell 30 inch church bell I have has been sitting outside on the ground for many years. The amount of rust is very small considering conditions. The bell has a date cast in the inside indicating the bell was cast in 1916. I have read that the cast CS Bell used a higher carbon steel alloy. Do you think this has helped with the lack of rust?

    • #26040

      “Amalgam” is not the name of a metal. It means “mixture,” and refers to the fact that the metal of these bells was a mixture of iron/steel and other things. The generic term “steel” actually covers an enormous variety of iron-based alloys and mixtures, many of which include other elements, and all of which are heavily influenced by the nature of the process used to produce them. Unfortunately I have never found a metallurgical analysis that tells just what components and processes were used by C.S.Bell and other manufacturers of iron/steel bells.

    Could be. Rumsey&Co made iron bells and most of the surviving ones have flaking rust clots on the bigger sized ones. I have a Goulds no 33 Goulds quit making bells many many years ago. They renamed the company ITT Goulds MFG and only make modern water pumps world wide. I do not know where the Goulds and Rumsey patterns went. Probably thrown away.

      I contacted “Prindle Station” about the church bell and they confirmed the date cast inside the bell is the casting date. Here is a photo of the bell taken today.

    Hello everyone
    I just acquired a NO 34 cast iron bell made by C S BELL COMPANY.
    This bell is missing the clapper . Does anyone have a picture or know the size and look of what the clapper should look like ?

  • #26084

    Go to Brosamers Bells and have a look at the pics of the cast iron bell pics There is a number 30 there. The 34 clapper would look just like it but a small bit larger for yours.

    Still in the process of restoreing my NO 34 cast iron bell.
    Thank you for the information about the 4″ cast iron clapper size.
    does it matter it the clapper is cast iron or a piece of steel round stock turned on a metal lathe ?

    Second question
    I have noticed that the yoke on the bell has alot of excess movement between the two.
    Is there normally any material between the yoke and the cast bell? Like maybe leather? Or is it normally a tight fit between them both or some sort of clearance? I am thinking that maybe throught the years maybe the center bolt has wore or rusted to a little smaller diameter?
    I have not separated the yoke from the bell yet, but I will soon .
    Thank you

    Finally had time to separate the yoke from the no. 34 bell . Glad I did , the 1″ x 12″ bolt was so rusty and corroded , it was only 3/8″ in diameter in 2 spots . I still need to fabricate the clapper and I will have to fabricate the troll springs now I am finding out
