| titleOfInvention | Piano hammer and method for making same |
| abstract | PIANO FORTE HAMMER AND METHOD FOR MAKING SAME Abstract of the Disclosure A piano forte hammer has an elongated head with a nose defining side surfaces, and a felt body disposed to extend about the nose. The felt body has a nose region for contact upon a piano string and first and second tall regions having surfaces affixed in contact upon the head side surfaces. The felt body, in the tall regions only, contains a predetermined measured amount of acrylic copolymer, the felt body nose region being essentially free of the acrylic copolymer. The hammer may be formed by a process including the steps of; providing a first volume of aqueous solution containing the predetermined measured amount of acrylic copolymer in a slot; disposing a first tall region of the felt body, prior to assembly about the nose, in solution in the slot; allowing the felt body to draw essentially all of the solution from the slot, into the first tall region only, by natural wicking action; and repeating the process for the second tall region of the felt body, the nose region being left essentially free of acrylic copolymer. |
