Description

UNITED STATES PATENT OFFICE.
GEORGE GARDNER, OF CLARKSVILLE, NEW JERSEY.
Specification forming part of Letters Patent No. 40,402, dated October 27, 1863.
To a/ZZ whom it may concern:
Be it known that I, GEORGE GARDNER, of
, Clarksville, in the county of Hunterdon and State of New Jersey, have invented a new and Improved Machine for Cutting Veneers; and I do hereby declare that the following' is a full, clear, and exact description of l he same, reference being had to the accompanying drawings, making a part of this speeication, in Which- Figure 1 is a vertical section of my invention, taken in theline x, Fig. 3 Fig. 2, a front view of the same; and Fig. 3, a plan or top view of the same.
Similar letters of reference indicate corresponding parts in the several figures.
The log or bolt is attached to the reciprocating gate or frame, and the knife or cutter is attached to a stock which is secured to a sliding bed, all being arranged in such a manner as to insure the work being done in an expeditious and proper manner.
To enable those skilled in the art to fully understand and construct myinven tion, I will proceed to describe it.
Arepresents a framing, whichis constructed of two parallel side pieces, a, a, connected by cross-bars b b, and B is a horizontal sliding bed which is placed on the side pieces, a a, and has two parallel cleats, c c, secured to its under surface-one near each end-said cleats being fitted in grooves d d, ina-de longitudinally in the upper surfaces of the side pieces, a, e. These grooves and cleats serve as guides for the bed, and they are made of dovetail form in their'transverse section, to prevent the bed from rising out of its proper position.
On the bed B at its inner end there is permanently secured a block, G, which extends nearly the. whole width ofthe bed. This block serves as a stock for a knife or cutter, D, and it has a slot, c, made longitudinally in it and of V form in its transverse section, as shown in Fig. l. This slot c extends nearly the Whole length ot' the stock C, and the former serves as a throat for the knife or cutter D, which is secured to the inner surface of the stock C in an inclined position, the upper edge ofthe knife, which is the cutting edge, projecting outward beyond the lower edge, as shown clearly in Fig. l.
F represents a gate or frame, which is formed of'a horizontal bar or plate, f, attached at its ends to cleats or springs g g, which are parallel with each other and have an inclined position, as shown clearly in Fig. 2. These cleats or strips g g are fitted in grooves la lz, which are made in the inner sides of parallel bars @'17, said bars having an inclined position corresponding to the inclination of the cleats or strips g g, as shown in Fig. 2. The inclined bars t' z' are rmly secured in the framing A,
and the gate or frame F is allowed to work freely up and down between said bars, the former havin g areciprocatingmovernent given it by means of a pitman, G, the upper end. of which is secured by a pivot, j, to the outer side of the bar or plate f, the lower end of the pitman being attached by a pivot, 7c, to a crank-pulley, l, which is on a shaft, m, in the framing A.
H represents the log or bolt from which the veneers are cut. This log or bolt is steamed, as usual, and is secured horizontally by bolts or screws tothe inner side ofthe bar or plate f of the gate or frame F. Each time the gate or frame descends a veneer is cut from the log or bolt H, and as the gate or frame has an oblique movement, owing `to the oblique or inclined position of the bars t' t', it Will be seen that a drawing cut is obtained, and the veneer is consequently cut from the log or bolt with the ,greatest facility, and a clean, smooth cut obtained. Each. time the gate or frame F reaches its highest or culminating point, and the log or bolt H is above the knife or cutter D, the bed B is shoved directly by hand or any suitable mechanism toward the gate or frame, and the knife or cutter is then in proper position for the descent of the log or bolt to cut a succeeding veneer. The inward or feed movement of the bed B is determined by the upper part of the stock C, which comes in contact with the lower part of the log or bolt, as will be understood by referring to Fig. 1.
The shaft m may be operated by any convenient power.
I am aware that obliquely-moving gates are commonly employed in Woodworking machines, sometimes for carrying the knife and sometimes the bolt. I therefore do not claim any novelty iu the main principles of my mato the forward edge of the table Rand the knife D, xed obliquely in the steek C, when al1 the said parts are constructed and arranged in the manner and for the purposes herein shown and explained.
GEORGE GARDNER.
