\VILLIAM H. WILLIAMS, OF LONG ISLAND CITY, NEW YORK.

VENEER-MACHINE.

SPECIFICATION forming part of Letters Patent No. 269,363, dated December 19, 1882.

Application filed August 16, 1882. (No model.)

T 0 all whom it may concern Be it known that I, WILLIAM H. WiLLIAMs, of Long IslandGity, in the county of Queens and State ofNew York, have invented an Im proved Veneer-Machine, of which the following is a specification.

Figure 1 is a plan or top view of my improved veneer-machine. Fig. 2 is an end elevation of the same. Fig. 3 is a front view on an enlarged scale of part of the same. Fig. 4 is a front view of the machine, and Fig. 5 an enlarged end view thereof, but without the part N.

This invention relates to a new machine for cutting veneers or slices of wood off a blockor piece of timber; and it consists in the new mechanism, hereinafter described, for holding and adjusting the block, for holding and adjusting the knife, for regulating the thickness ofthe slice or veneer, and for actuating the parts during the act of cutting the veneer off the block. The machine operates to move the block in an oblique direction downward, while the knife is held stationary.

In the drawings, A represents the block of wood to be cut. The sameis held by series ofdogs a and b against the face of a sliding frame, B. The upper series of dogs, a, can be adjusted vertically by screws (1, and the lower series of jaws or dogs, b, can be adjusted by screws 0. The screws (1 and e are arranged in pairs along the face of the slide B,asiudicated in Fig. 3, and are all operative from the upper end of said frame 13. For this purpose the screws d are right-hand screws, having righthand threads, and the others, 6, have left-hand threads. The nuts for these screws are all set into the upper partof theframing B, and thus, by suitable wrenches taking hold of the upper parts of these screws, either set of dogs can be raised or lowered at will. This is a great convenience, as it does away with the necessity heretofore existing of crawling under the machine for the adjustment of the lower dogs. The frame B is placed against the face of a. fixed supporting-frame, D, which fixed supporting-frame has three (more or less) inclined face-posts, f f, which are grooved on theirfronts to receive dovetailed projections g, which project backward from the movable frame B.

Thus the frame B is capable of moving up and down in an obliquedirection along the grooved guide-postsf. For the purpose of communieating this motion, I employ the following mechanism:

In a suitable framing, E, are the bearings of a driving-shaft, F, which receives rotary motion by suitable mechanism, and which gears by a pinion, It, into a large toothed wheel, 2', on the shaft j. This toothed wheel ihas a crank-pin, Z, placed by preference outside the diameter of its teeth, and connects by a rod, m, with a sliding rack, G, which slides in suitable supports of the frame D. The rack G is toothed and meshes into pinions n n, that are mounted up'on shafts H. These shafts, attheir front ends, carry further pinions, 0, that mesh into inclined racks 19, (see Fig. 2,) that are affixed to the back of the frame B, so that as the rack G is moved back and forth the shafts H H are levolved first in one direction to lift the frame B and the block of wood A obliquely, and then in another direction to carry the said frame B and block A down obliquely. The racksp are parallel with the inclined posts f. I regard this arrangement of sliding rack G, in its connection with the sliding frame B for holding the block A on a veneer-cutting ma chine, as a very importantimprovement, as it renders the machinery steady and makes it very powerful, doing away with the liability to get out of order that existed in previous inachines.

The sliciug knife or cutter I is secured in a frame, J, which stands on a platform, J that rests on an extension of the frame D, and which can be adjusted toward or farther away from the block A by a shalt, L, (see Fig. 1,) gearing into screws mm, that connect with the sliding frame J through nuts m fastened to the latter. A suitable hand-wheel, r, on the shaft L is turned by hand or automatically to feed the knife forward after every slice has been; cut off. Upon the frame J, which carries the knife, are supported blocks 8 s, which carry a blade, N, that controls the thickness of the slice-that is to say, the block is about as long as the knife 1, and is supported at a proper distance back of the knife and near its edge, and by screws t t the blocks s and the block can be adjusted to regulate the thickness of the slice or veneer.

Operation: The block A is fastened in the sliding framing B. Thefraine J is moved ahead to bring the knife I in position, whereupon the framing B is moved down in a slanting direction to cutoff one slice. ThefraniingB is then raised with the block, the knife adjusted forward the thickness of another slice, the framing B moved down again in a slanting direction, 850., until another slice is cut off.

I claim- 1. In a veneer-cutting machine, the sliding frame B, adapted to guide the block A, incombination with the dogs a b, and with therighthand screws (1 and the left-hand screws 0, for allowing the independent adjustment of all and each of said dogs from one end of the machine, substantially as described.

2. The combination of the slidingframingB, carrying the block to be out, and having the inclined rack or racks p, with the framing D, having inclined guide-posts f, and with one or moreshafts, H, having pinions 0 and n, and w-i th the reciprocating rack G, substantially as herein shown and described.

3. The combination of the fixed frame D, having inclined guide-posts f, with the sliding framing B, adapted to hold the block to be cut, and with the frame J and knife I, and with mechanism, substantially as described, for adjusting the position of said frame J, as set V forth.
