WOOD-VENEER JOINTER AND SHAPER.

SPECIFICATION forming part of Letters Patent No. 535,162, dated March 5, 1 895. Application filed April 23, 189 1. Serial No. 508,702. (No model.)

To aZZ.zuh0m it may concern:

Be it known. that I, GUSTAVE H. CARLSON, a subgect of the King of Sweden and Norway, residing at Hoquiam, Ohehalis county, State of Washmgton, have invented a certain new and useful Improvement in Wood Veneer .lolnters and Shapers, of which the following is a specification.

My invention relates to improvements in a wood veneer jointer and shaper for preparing wood veneer for baskets so that any two of the pieces cut, when laid across each other at right angles the one over the central part of the other, and the four ends of said pieces are bent upward at right angles to the edges when the one crosses over the other, that the ends when so bent upward form with the parts crossing each other a basket in perfect and desirable shape for holding fruit or for other purposes.

The jointer and shaper consists of a crosshead of metal or any suitable material set in a frame, and having four sides, two of which are elongated and curved to conform, to the required shape of the pieces out, which, with the two straight sides, form the ends, making an enclosure open at the top'and bottom, into which the veneer pieces as cut slide upward. From the inside lower portion of the elongated sides of the cross-head extend metallic cutters or knives of the same shape and curvature, as the elongated sides of the cross head; the ends of said knives curving a little, so as to slightly round the corners of the veneer pieces when out. To the outside of the upper ends of the cross head is attached a bail by means of a pin, and on which it may freely move, which is for the purpose of lifting the same after its descent in shaping and cutting the veneer pieces. To the middle part of said bail is attached at its lower end, an upright handle or lifter through the upper end of which passes the bent portion of the shaft which operates the jointer and shaper, said shaft being held in place by means of supports extending down from the top of frame to which they are secured, and in the lower end of which it revolves. Slide pieces are secured to the ends of the crosshead which move up and down in upright plates attached to the insides of the frame part, having grooves into which the slides fit, thus holding said hub being of a larger circumference than the inner part of the same. The upper end of the pawl has a projection that extends out a little over the smaller circumference of the hub, so as to slide over the end of the upright lever that is attached to the side of the frame part bya support at a point about onethird of itslength above the lower end of the same, said lever being fastened to said support by a pin, allowingit to move easily back and forth. The lower end of the lever moves upon a projecting piece attached to the frame, and is held in position by a spring also fastened to the outside of the frame support, extending over the ends of said lever to spring the upper part of the lever back under the projecting part of the pawl, which, as the pawl slides upon it, the lever raises the pawl from the groove in the hub of the pulley, and cuts off all motion with the hub and axle and allows the driving pulley to freely revolve on the end of the shaft. A spring is fastened upon the outside of the hollow hub, the end of which extends over and rests against the upper end of the pawl to spring it back into place when the lever is moved one side to the small circumference of the hub; and as the pawl is pushed back by it, it enters the groove in the pulley hub and sets in motion the shaft. Directly under thejointer and shaper, extending from one side of the frame to the other, is a crosspiece or table upon which there is placed an additional block piece of Wood, upon which the veneer sheets slide, as they are pushed under the jointer and shaper, and upon which it acts in cutting and shaping the-veneer pieces. From the inside of the bottom same.

places cut into which the ends of the strips enter. Said strips are turned up at the lower ends, and are for the purpose of catching and holding within the shaper, the pieces cut out in the descent of the knives. On the upper back side of the cross head, two guards are set to prevent the strips from falling that way when discharged from the top; also there is an upright guard placed on the back of the cross piece or table, against which the veneer sheets are pushed and prevented from going only so far. An apron is attached to the front of the frame to support the sheets, and from which they are pushed forward under the jointer or shaper. It is hinged at one end to the table, and is supported at the other end by a swinging leg, which, when not in use, may be turned under the apron, and the apron dropped. I attain these objects by the mechanism illustrated in the following drawings.

Figure 1 is a front vertical elevation of the machine, with frame jointer partly broken. Fig. 2 is a side vertical elevation of same partly broken; Fig. 3, asectional plan of same taken through line x-a; Fig. 1, with feed apron left out; Fig. 4, a detail front view of driving hub and shifting lever; Fig. 5, a detail side View of same partly broken, showing pawl in raised position; Fig. 6, a detail front view of driving pulley; Fig. 7, a detail side View of the same.

A, represents the frame support; B, the cross-head part of jointer and shaper; O, the knives attached to the cross-head for cutting and shaping the veneer pieces; D, the bail fastened on the crosshead at its upper ends; E, the upright handle or lift attached to the upper middle part of the bail; F, the revolving shaft; G, the shaft supports in which it is secured and revolves; H, the hub on the end of the shaft, the outside part of which is hollow; I, the driving pulley on the end of the shaft; J, the grooved hub of driving pulley; K, the shifting lever, the upper end of which rests on the hub of the shaft and is used to operate the pawl in said hub to cut off motion of driving pulley; L, the pawl inserted into the hollow part of hub on shaft, and which slides into the groove in hub of driving pulley to communicate motion to the shaft; M, the spring on the outside of hub, the end of which rests 011 the pawl to press it into the groove in the hub of the driving pulley for communicating motion to the shaft; N, the lever support attached to the frame; 0, the table cross piece for supporting the veneer sheets when operated upon by the cutter; P, block piece upon the table against which the knives act in cutting the veneer sheets; R, the metallic supporting strip for catching and holding the veneer pieces when out inside the shaper; S, slide pieces attached to the crosshead; T, upright grooved plates set on the sides of the frame in which said slides move when the machine is operated; U, the feed apron from which the veneer sheets are fed under the knives; V, swinging leg attached to the under side of the table to support it; a, pin holding bail; b, guards on the back of the crosshead to keep veneer-shaped pieces from falling in that direction when being discharged from the top of the header; d, guard on the back of the table cross piece, against which veneer sheets are pressed to hold in true position for cutting; e, groove in the hub of the pulley into which the pawl slides that is inserted in the hub of the shaft. to communicate the motion of the driving pulley to the shaft; f, spring operating at lower end of the shifting lever to spring it into place for raising the pawl and cutting off the motion of driving pulley;

g, the slide or frame on which lower end of the lever moves; h, hinge attaching apron to the table cross-piece in the frame; 7 hinge support to the apron.
