Description
'UNITED STATES PATENT OEEICE.
BENJAMIN F. BE'ITS, O1*` TONAWANDA, NEW YORK.
IMPROVED MACHINE FOR CUTTING THIN LUMBER.
To all whom it may concern:
Be it known that I, BENJ. F. BET'rs, of Tonawanda, county of Erie, State of New York, have invented a new and useful Improvement in Machines for Cutting Thin Lumber; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, ofwhich- Figure 1 is a plan with movable bed-plate in position g' Fig. 2, likewise a plan with said bed-plate removed for the purpose of showing the arrangement beneath for elevating or depressing it, and Fig. 3 a side elevation of screw and eccentrics.
B is the box Within which the block of wood to be cutis placed; b, the rods or guides upon which said box slides; A, movablebed-plate; c, knife attached to the immovable bed-plate D; m, the eccentrics upon which the movable bed-plateArests.
The block of wood to be cut is placed within the box B, its own weight causing it to rest upon the bed-plate A. The box is then moved forward upon the oblique guides b, carrying the block forward and laterally (corresponding to the motion of the box B) over the knife c, thereby shaving ol from the under side of the block a board equal in thickness to the height of the edge of the knife c above the bed-plate A. The knife c, being set diagonally to the box B, lesscns the tendency to check the lumber.
The machine is gaged for cutting di'erent thicknesses by causing the eccentrics m (upon which the bed-plate A rests) to rotate conjointly, thereby elevating or depressing the bed-plate, thus increasing or diminishing the vertical distance between the bed-plate A and the knife c.
I do not claim the principles involved in this machine; but
I do claim the combination and arrangement of those as herein described, viz
The sliding box with oblique motion, thereby giving by movement of the block a drawing cut to the knife, in combination with the diagonal position ofthe knife attached to the immovable bed-plate, and the arrangement of ecceutrics for elevating or depressing the movable bed-plate. The bedplates here referred to are plane surfaces, and when plate A is raised to a level with edge of knife, both bedplates and upper side of knife form one plane surface.
BENJ. F. BETTS.
