Forming Machine for Wool Hat Bodies.] It will not have escaped observation that this ingenious piece of machinery is applicable only for fur, the filaments of which are short and less inclined to tangle than those of wool, but another and no less useful piece of mechanism has been invented for forming the bodies of wool hats, and like the other has entirely superseded the use of the bow in all large factories where wool hats are made. It consists of a modified common carding machine, the sliver from which is conducted to a set of double conical blocks that are placed base to base, and which slowly revolve upon their axes in front of the carding machine, and the sliver is received and wound upon these combined blocks to the required thickness, sufficient for one hat, both blocks being covered at the same time. This machine which carries the blocks has a horizontal vibratory motion, or swaying backwards and forwards, that enables the sliver to be wound in a systematic manner on the cones, with a varied thickness of material for brims and crowns, and causing also the fibres of the wool to lie in a diagonal position, as layer upon layer covers the blocks. The bodies of the two hats, each of a conical figure, are thus made over the surface of a double cone which are separated by cutting them along their middle or base line, and slipping them off at the end. They are now ready to be wetted, shrunk, and felted in the usual manner by the regular hatter. Shoes and Gaiters of Felt. We will here describe the making of felted gaiters and shoes, which is similar to the art of hatting. There may be other and better methods, as the expansive stretching nature of felt may admit of other modes. The wearer of these gaiters may walk upon the slippery pavement with comfort and full confidence, and if furnished with a leather or rubber under-sole, they are a neat, easy, comfortable cover for the feet.
