MACHINE FOR CHAMFERING VENEERS.

Specification of Letters Patent No.

To all whom "it may concern:

Be it known that I, GEORGE WILLIAMSON, of the city of Newark, in the county of Essex and State of New Jersey, have invented a new and useful Machine for Chamfering off the Edges of Veneer for Boxes and other Articles of Manufacture; and 1 do hereby declare that the following is a full, clear, and exact description of the nature and object of my invention, reference being had to the accompanying drawing, making a part of this specification, which drawing is a perspective view of the whole machine.

A, is the bed plate.

B, B, are the ways and B, is a plate of metal connecting them together.

C, is the frame or table, attached to and constructed to slide upon the ways B, B, upon which is placed the material E, to be chamfered.

D, is a springing clamp attached to the frame or table C, and adjusted on hinges as represented, and e, is an under part of the clamp D, adjusted at s, and having a spring between the upper and lower parts as represented for the purpose of properly adjusting the clamp D, while pressed down upon the material to be chamfered.

F, is a revolving cylinder or cutter head, upon which is adjusted the knives 7a, 7a, 70.

m, is a spring which holds the material while being chamfered.

The operation of my invention is as follows: The ways are adjusted in the middle upon a pivot at p, which is for the purpose of regulating the size of the chamfer 29,942, dated September 4, 1860.

required. This is effected by loosening the screw 1', and tightening the screw 12, which raises the end of the ways at r, and lowers the end at 1*, thereby offering less surface of the material to be chamfered to the action of the knives, and consequently producing a smaller chamfer, and so by reversing the process it has an opposite effect, viz., producing a larger chamfer. The operator is stationed next the handle and the frame C, being at the farthest end of the ways B, B, from him, the material to be chamfered is placed upon the frame or table C, as represented. The clamp D, is then pressed down upon the material to be chamfered holding it properly on the frame or table C. The frame or table C, is then drawn by means of the clamp D, toward and under the revolving cylinder or cutter head F, when the revolving knives 7c, 70, 70, will chamfer the material as it thus passes under them, and the spring m, will keep the end of the material pressed down upon the frame or table C, while the said material is being chamfered.

hat I claim as new and of my own invention and desire to secure by Letters Pat ent of the United States, is

The combination of the adjustable ways B, B, the frame C, springing clamp D, and spring m, substantially in the manner and for the purposes described.

GEORGE WILLIAMSON.
