VENEER-MACHINE..

SPECIFICATION forming part of Letters Patent No. 501,395, dated J' uly 11, 1893.

Application filed November 17. 1892. Serial No. 452,283. (No model.)

To @ZZ whom it may concern,.-

Be it known that I, WILLIAM H. WILLIAMS, a citizen of the United States, residing at Long Island City, in the county of Queens and State of New York, have invented new and useful Improvements in Veneer-Machines, of Which the following is a specification.

This invention relates to a machine for cutting veneers and it consists in certain novel features pointed out in the following specilication and claims and illustrated in the annexed drawings, in Which- Figure l,is a rear elevation ofpa veneer machine. Fig. 2, is a section along :c a: Fig. l. Fig. 3, is a detail face view of a guide. Fig. 4, is a transverse section of the guide of Fig. 3. Fig. 5, is a side elevation of a modiiication sectioned along an Fig. 6. Fig. 6,is a section along :r2 m2 Fig. 5.

In the drawings the letter A indicates a log or piece of wood clamped or secured in any suitable well known way to the block carrier or stay log B. The base or su pport D carries guide arms f along which the carrier B is caused to slide back and forthl The carrier B is guided along the arms f by any well known suitable means such as V shaped or dovetailed tongues or grooves. The links are jointed or pivoted at y to the stay log or carrier and at w to the arms or levers v fulcrumed at I-I. The fulcrums or pivots I-I are provided with actuating gears u engaged by an actuating rack G which is moved or reciprocated by link fm, and crank pin Z receiving motion from driving shaft F. The rack G is mounted in and supported by a horizontal guide-way formed in the base or support D, Fig. 2, and is located above both of the gears u, so that the teeth at one side of the rack engage both gears. As theV rack G is reciprocated by the crank pin Z the ygears u and levers o are oscillated so as to cause the carrier B to travel back and forth along the guide arms f.

In place of traveling back and forth along guides fthe stay log or carrier B might be rotated or oscillated back and forth as in Fig. 5.

The carrier B in its reciprocations is made to carry the log A past a cutter or slicer I carried by a frame or support J, whereby the veneer or strip of material is sliced or cut off the log. The frame J is adjustable toward and from the log A so that the cutter can be set for the proper degree of slicing. The guide or gage A determines the proper position of the slicer or knife I.

As the log A is generally heated or boiled before being cut or sliced the guide A is apt to become heated not only from the heatl of the log but also from the friction exerted by the log in moving past the cutter. By providing the face of the guide support B with lateral shoulders or projections C and securing the guide or gage A to such shoulder the guide is held a certain distance away from the support B so as to form a series of aircirculating spaces between the support B and -the guide A for the purpose of cooling the latter. To allow the guide A to expand and contract with variations in the temperature, said guide is provided with a series of longitudinal slots D for the pins, bolts or fasteniugs E which hold the guide to the shoulders C. The guide can thus expand and contract without bending or losing its accuracy. The center point or portion of guide or steel A can be rigidly fixed instead of being fixed by a pin and slot connection since if the guide is free to expand and contract from the center toward each end the guide will be free to remain straight or accurate. It desired the knife I can be fixed to shoulders by movable fastenings so as to be ventilated and free to move the same as the guide.

What I claim as new, and desire to secure by Letters Patent, isv l. The combination with a stay log, its support and mechanism substantially as described for actuating the stay log, of a cutter I and a guide A and a support B provided on its face with a series of lateral projections C to provide a series of air-circulating spaces between the guide and the support, substantially as described.

2. The combination with a stay log its support and mechanism substantially as described for actuating the stay log, of a cutter I a guide A and a support B for said guide, said guide having a series of longitudinal slots D through which fastenings extend to enable the guide to expand or contract length- Wise, substantially as described.

3. The combination with a stay log its support and mechanism substantially as described for actuating the stay log, of a cutter I, a guide A and a support B for said guide, the center portion of the guide being rigidly fixed to the support and the remainder of the guide loosely attached and movable length- Wise on its fastenings to provide for longitudinal expansion or contraction of said guide from the rigidly fixed central portion thereof substantially as described.

4. In a veneer-cutting machine, the combination with a base or support, having a hori- .zontal guide-Way, a cutter and a reciprocating stay-log, of guide arms f for the stay-log, p ivots H having gears to, and crank-arms QJ, link pivotally attached to the stay-log and crank-arms, and a reciprocating rack G mounted in and supported by the horizontal guide- Way of the base or support at a point above both of the said gears to oscillate them with their pivots and thereby reciprocate the stay- 10g onthe guide arms to and from the cutter for severing veneers from a log carried bythe stay-log, substantially as described.

5. The combination with a stay-log, and mechanism for guiding the same, of a support B', and a guide A having longitudinal slots D', said support having on its face a se- WILLIAM I-I. WVILLIAMS.
