VENEER-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 767,466, dated August 16, 1904;.

Application filed December 3, 1903- Serial No. 183,569. (No mode1.)

To n/ZZ whom, it may concern.-

Be it known that I, J osnrn WOLEINGER, a citizen of the United States, and a resident of Dundas, in the county of Calumet and State of WVisconsin, have invented certain new and useful Improvements in Veneer-Cutting Machines; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention consists in certain peculiarities of construction and combination of parts hereinafter particularly set forth with reference to the accompanying drawings and subsequently claimed, its object being to provide for economical cutting of a continuous woodveneer strip from a rotatory tapered block by means of a pivotal knife having constant automatic adjustment from an angle corresponding to the original taper of the block toward a line parallel to the axis of said block.

Figure 1 of the drawings represents a partly-.

sectional plan view of a wood-veneer-cutting machine provided with an automatically-adjustable knife in accordance with my invention; and Fig. 2, a vertical longitudinal section View of the machine, this view being indicated by lines 2 2 in the other figure.

Referring by letter to the drawings, A indicates the frame, B the chucks, and C the chuck-spindles, of a wood-veneer-cutting machine, these spindles being mounted in bearings Z1 provided on said frame. Fast on each chuck-spindle is a spur-wheel D, in mesh with a spur-pinion E on a power-shaft. F, and in link-belt and sprocket-wheel or other suitable gear connection with one of the chuck-spindles is a shaft G, for which bearings c are provided on the machine-frame. The shaft G is in bevel-gear connection with the feedscrews H for the knife-carriage I, and the aforesaid frame is provided with bearings (Z for the screws.

As thus far described, the machine herein set forth is not materially different from those of common knowledge in the art to which my invention relates; but in wood-veneer-cutting machines as ordinarily constructed the knife is rigidly connected to the carriage, either parallel to the axis of the block to be cut or at an angle to said axis, accordingly as said block is' cylindrical or tapered.

In accordance with my invention a flange J of the knife J is connected by a pivot f with a forward lug of the carriage I, and said flange or knife-holder is provided with a segmental slot g, the radius of which extends from the center of said pivot. A stop-pin h on said carriage engages said slot. The end of the knife flange or holder adjacent to the slot aforesaid is connected by a link K with a nut L on a screw M, that turns in bearings 71, with which the machine-frame is provided, and fast on said screw is a spur-pinion in mesh with a spur-wheel 76, fast on one of the screws H, upon which the carriage I is traveled. The speed of the swing of the knife or its holder on the pivot f is determined by the gearing connecting the screw M with one of the screws H, and as the carriage I feeds forward there is constant automatic adjustment of said knife from an angle corresponding to the original taper of a block N, chucked in the machine toward a line parallel to the axis of the block, whereby the result being a continuous strip of veneer from which to cut segments that separately constitute the whole or part of a flaring vessel-body. It is also to be understood that the veneer is of gradually-decreasing thickness in the direction of the taper of the block from which it is cut, this being due to increasing rapidity of swing on the part of the knife in the direction away from its pivot, and vessel-bodies of predeterminal size derived from said veneer will be of uniform flare.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A Veneer-cutting machine comprising a carriage mechanism for feeding the same, a knife in pivotal connection with the carriage, a screw cooperative with the carriage-feed mechanism, a nut on the screw, and a link connecting the knife and nut, said knife being operative to cut a continuous strip from a primarily-tapered block having rotatory motion in the machine.

2. A veneer-cutting machine comprising a screw-feed carriage, aknife in pivotal connecl carriage feed mechanism for automatically 15 tion with the carriage, a screw in gear connection with a carriage-feed screw, a nut on the auxiliary screw, and a link connecting the knife and nut, said knife being operative to cut a continuous strip from a primarily-tapcred block having rotatory motion in the machine.

3. A veneer-cutting machine comprising a feed-carriage, a knife connected by a pivot with the carriage, a pin on the carriage engaging a segmental slot of the knife, the radius of the slot being from the center of said pivot, and means cooperative with the swinging said knife on its pivot from an angle of more or less degree toward a line parallel to the axis of a rotatory tapered block in the machine, the angle aforesaid being that of the original taper of the block.

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of Visconsin, in the presence of two witnesses.
