MACHINE FOR EDGING BOXES 0F WOOD VENEER WITH SHEET METAL.

SPECIFICATION forming part of Letters Patent No. 539,765, dated May 21, 1895. Application filed April 17, 1894.. Serial No. 507.878. (N0 model.)

.To aZZ whom, it may concern:

Be it known that I, MILTON A. CLENNAM, a citizen of the United States, residing at San Francisco, county of San Francisco, and State of California, have invented a certain new and useful improvement forfastening and crimping tin or metal folded strips upon the edges of wood veneer material for fruit-baskets or for other purposes, of which the following is a specification.

My invention relates to improvements for fastening or crimping tin or metal folded strips upon the edges of wood veneer material for fruit baskets or for other purposes, so as to bind the upper edges of the sides firmly together, and thus give strength and durability to .the thin veneer basket; or to the parts of the material thus bound by the metal strips.

The folded metal strips partly open are placed between the jaws ofthe machine with the partly open edges turned up, between which the edges of the wood veneer material are inserted. A horizontal lever, h, is mounted on a support at the bottom of the frame. To the rear end of this lever is attached an upright rod, 2', that is connected at its upper extremity to the end of a bent lever, is, that operates the pawl lever and hub stop, 9, which forces inward the pawl, H, in hub, P, on axle,

L, of the ratchet wheel, E and at the same time stops the hub from turning down as the pawl is disengaged from the ratchet. A bent lever is also attached to the frame which moves the jaws and extends down to near the upper side of the aforementioned, horizontal lever, so that when the operator presses with the heel upon the horizontal lever and at the same time pushes with the end of his foot against the end of the upright lever moving it forward, the bent upper part lifts against the arm that moves the jaw piece to which it is attached, lightly closing the jaws after .the

placing of the metal strips therein, and the chine to act, when starting thesame.

insertion of the edges of the veneer material holding these firmly in-position for the ma- On the removal of the pressure of the foot on the two levers, the pawl lever and hub stop g slide out from the hub, which movement allows the pin I to be pressed outby the spring and engagethe pawl with one of the ratchet teeth,

of the ratchet wheel, E which latter in its revolution carries the eccentric strap, F, at-

.forward, which turns the Wing pieces on the sides of the jaws inward, bending the straight metal pieces at right angles to the part held in the jaws. The bent portion not being long enough to extend across the adjoining side of the basket edge, another strip is placed lapping over it into the open jaws, andthe edges of the adjoining side of they basket is placed therein and the levers are moved, and the connection is made by the pawl to the pulley. The jaws are again closed fastening and crimping the strip'upon the veneer'edge as before, and in this manner the edges of the veneer, material are bound. When the pawl- Figure 1 isa sectional side elevation of the machine, taken through line a: a: on Fig. 2, with the jaws closed; Fig. 2, a rear end elevation of the machine; Fig. 3, an enlarged detail sectional elevation of mechanism, as shown in Fig. 1, with jaws open; Fig. 4, an enlarged detailplan of the same in part section; Fig. 5, an enlarged detail-front elevation of the ratchet-wheel and pawl, taken through line y g on Fig. 4; Fig. 6, a side elevation of, the same; Fig. 7, a detail of veneer and metal strip.
