Specification forming part of Letters Patent-No. 29,535, dated August 7, 1860; Reissue No. l, I4 7,`dated February 26, 1861.

Be it known that I, JOHN M. WOOD, of Senecayin the county of Ontario and State of New York, have invented a new and Improved Machine for Peeling Willows, &c. and-I do' hereby declare that the following is afull,

` clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, in whichi Figure l represents aV perspective view of my invention. Fig. 2 is a plan or top view of the same.

Similar letters of reference in both views indicate corresponding parts.

My invention consists 'in the arrangement of a circular revolving disk with a superincumbent roller having a graduated screw on its surface, and so arranged in reference to the disk that when they are both Cin motionl `twigs of willow, or other twigs of a similar nature,- will pass between them and be speedily denuded of their bark, leaving the twig in the proper condition for manufacturing purposes.

To enable those skilled in the art to make and use my invention, I will proceed to -describe its constructionand operation with reference to the drawings.

The working parts of my machine are supported by a suitable frame, Il, made of wood or'of any other convenient material. This frame forms the bearings for the vertical shaft P, tothe upper end of which the disk D is firmly attached.; 'The upper surface of this disk is covered 'with some suitable materialsuch as gutta-percha, india-rubber, or leather, or with sheet metal, sheet-copper being the best-so that it forms a friction-surface, and

on the lower end ,of its periphery cogs are made, which gear into the wheel O on the arbor R. 0n the upper endof thisshaft is the bevel-wheel E, which gears into a bevelwheel, E', on the sha-ft of the screw-cylinder S. Motion is imparted to these parts by `means ot' a pulley on the shaft P, or in most casesit may be found to be most convenient to extend the shaft of the screwcylinder beyond its bearings, thereby affording room for apulley which may serve as the drivingpulley of the machine. The arbor R passes freely through the top bar, F', of the frame, and it is journaled in two stirrups, which are Vnot essential.

firml'ylsecured to said frame. Itis so arranged that itis allowed to rise and fall freely,

ing through between the disk D and the screw-cylinder S. Instead of arranging the springs on the ends of 4the screw-cylinder, however, the shaft I of the disk D might be so arranged that it will allow said disk to rise and fall simply by placing a spring under this shaft, and in both cases the springs Imust be so regulated that when nothing interferes` between the screw-cylinder and the disk the surfaces of the two-are in contact with each other, and atthe same time the spring or springs must be sufficiently strong to exert the necessary pressure to denude or peel the twigs passing through betweenthe two surfaces. In order to facilitate the operation, the end c of the screw-cylinder is slightly conical, so that itreadily seizes the thin ends of the twigs and carries them into the screwed part of the cylinder. The thread' on the surface of the cylinder S is gradually increasing, being finest at or near tothe end c, and it terminates in a circular groove, G, at the oppo! site end. Bykthus increasing the thread itV accommodates itself to the gradually-increasing thickness of the twigs; and I have made said thread to terminate in a-circular groove,

thereby facilitating the passage of the twigs from the machine. This groove, however, is

The operation is as follows When the machine is in motion, the twigs are fed to the screw-cylinder S one afterthe other-by putting the small ends of the same atvthe conical endyo of the cylinder. caught and drawn toward the screw and speedily stripped, and at the Sametime that the stripping process is in progress the-twig is carried along toward' thel end G, where it is thrown out entirely denuded. Sudden inequalities in the twigs are provided 'for by the arrangement of the springs or spring, which allow the rubbingsurfaces to accommodate themselves readily to yevery partof the twi'g` operating on it at all times.
