To all whom fitimag/ concern:

Beit known that we, WILLIAM A. Woon and JOHN U. LGVELAND, ot' the `village of Hoosick Falls, in the county of Rensselaer and State of New York, have invented a new and useful improvement on the machine commonly called and known as the Grain-Cradle; 7 and we do hereby declare that the following is a full and exact description ot' the same, reference'being had to the annexed drawings, making a part ot' this specification, in which- Figure l is a perspective view of the machine. Letter 2 represents where the metallic parts of teeth are joined to the wooden parts ot' teeth. i

The nature of our improvement and invention consists in making the teeth of the cradle whole or in part of hollow metal, and when only part is metallic the metal composes the lower end or extremity of the teeth, being the part that requires the most curve, and is twenty neheslong. The remainder ofthe teeth are composed of wood, and are attached to the metallic parts ot' teeth by entering the tube about three inches, and are seenredfby a wire pin passing transversely through the parts of teeth, as shown at Figt2 in drawings, the metallic teeth or parts of teeth being of the usual thickness, or nearly so, ot' the wooden teeth heretofore in use.

What We claim as our invention and improvement, and desire to secure bly Letters Patent, is-

The use of said hollow metallic teeth and hollow metallic parts of teeth, the metal being less liable than wood to relax and straighten.
