Rev. J F Lowe, W W Ward wrote this song, copyright 1937 in "Gleams of Glory" Owel W Denson, Owner. Used by permission. This is on the sheet music that I have.

From my searches I determined the W & M were by Paul Williams and Jimmy Martin. Key: C 4/4
but I have not been able to determine a publishing or copyright date.

I hope this is the one you're looking for.

1)
While we are living in this world of care,
Many the burdens that we have to bear;
But there's a prayer-bell at the Lord's right hand,
Give it a ring and He will understand.

CHORUS:
Prayer-bells of heaven,O how sweetly they ring,
Bearing our message unto Jesus the King;
When you are burdened down with trouble and care,
Ring on, and on, for God will answer your prayer.

2)
Three Hebrew children to the flames were thrown,
Because a mortal king they would not own;
Jesus delivered and the king then saw,
Prayer-bells of heaven beat a man-made law.

CHORUS

3)
When Paul and Silas both were thrown in jail,
They did not worry who would go their bail;
But on the prayer-bells they began to ring,
Off fell the stocks and they began to sing.

CHORUS

4)
Into the garden Jesus went to pray,
Until His sweat became as blood, they say;
Ringing the prayer-bells there in agony,
Bringing salvation that we might be free.
