10 a/ZZ whom it may concern.-

Be it known that we, WILLIAM E. Bnocx and ADDIE M. BROOK, of North Plainfield, county of Somerset, and State of New Jersey, have invented certain new and useful Improvementsin Veneering-lllachines, of which the following is a specification.

This invention relates to a machine for veneering tongue-and-groove boards or similar material; and it consists in the construction and novel arrangement of parts, as hereinafter set forth, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a top plan view of a veneering-machine embodying our invention. Fig. 2 is a rear elevation thereof. Fig. 3 is a transverse section of the machine. Fig. 4 is a transverse section of a portion thereof. Fig. 5 is a perspective view of a board as veneered with our machine, and Fig. 6 shows a push bar or lever employed.

Referring by letter to the drawings, A designates a bed-plate or table. It has a longitudinal channel Fin it forming abutments a ct, between which the mold B, hereinafter described, is designed to be placed. The rear edge of the raised portion of the bed-plate has an upwardly-extending abutment G, for a purpose hereinafter mentioned.

0 indicates a tilting gluingtable having trunnion-bearings e in arms D, extending rearward from the bed-plate or table A. At its upper inner edge the table 0 has an upwardly-inclined strip C, of metal or other suitable material. This strip is designed to enter the groove of a board (indicated in dotted lines) at an angle, so that the upper wall of the groove may be exposed for applying glue thereto. At its outer upper edge the table 0 has upwardly-extending spring-fingers O and the free ends of these fingers are turned slightly outward at an angle. The strip 0' and the fingers 0 form a clamp for securinga board to the table for the purpose of applying glue thereto. In inserting a 7 board its groove is first placed over the strip O, and then its opposite edge is forced down onto the table against the resistance of the spring-fingers 0 vided at one edge with an upward extension I), a main movable section 13*, having a pivotal or hinged connection 1' with the section B, and a pivotal or hinged connection it with the section B Atits inner free edge the section B has a longitudinal rib designed to conform the veneer to and around a portion of the bead formed on the board. At its lower inner edge the section B has a longitudinal groove and a downward projection d, designed to press the veneer against the shoulder adjacent to the tongue of the board.

In the initial operation of applying the veneer it is desirable to support the section B at a slightly-tilted position with relation to the section B. For this purpose we may employ pins J, extendedthrongh transverse holes in the section andinto sockets in the section Bias plainly shown in Fig. 3. Arib 0 extends inward from the inner surface of the upward extension I). This rib is designed to enter the groove of a board and force the edge of a veneer therein.

U is a force-bar employed in the operation of veneering. The bed-plate or tableA is provided with sockets U, adapted to receive the end of the force-bar, which will receive its fulcrum against the walls of these sockets. The force-bar U has a projection e, designed to bear against the edge or shoulder of a board adjacent to its tongue, as indicated in the dotted line, Fig. 3. l

e may employ an ejector for ejecting a finished board from the mold at the proper time. The ejector here shown comprises vertical rods Q, having a pivotal connection at their lower ends, with a foot-treadle P, which has a pivotal connection P with swinging links P The upper portions of the rods Q pass through holes in the bed-plate or table, and the section B is provided with holes registering with the holes of the bed-plate for the passage of the rods Q. To prevent a tooextended upward movement of the ejectorrods, they maybe provided with stops, (here shown in the form of shoulders Q,) which will strike against the under surface of the bed-plate.

The ejector is forced upward to eject a board by means of springs P secured at one end to the treadle and at the other end to the bed-plate. An arm or arms R, pivotally connected at the lower end to the treadle and engaging with keepers R on the bed-plate, serve to hold the ejector down or in its normal position against the resistance of the spring.

The operation of our machine is as follows: The glue is applied to the board when on the table 0, as heretofore described. The board is then placed on the table A between abutment G and abutment G on the section B of the mold. While in'this position the veneer is inserted into the groove of the board. The board and veneer are then transferred to the mold, and a force-bar is brought into use for forcing the rib 0 into the groove of the board,

which forces the veneer against the upper wall of the groove. This operation will bring the board and veneer wholly within section B of the mold, and the parts B B are forced successively down upon the work. After the glue shall have become sufliciently dry the mold is opened, and then the ejector is operated to force the veneered board out of the mold.

Having described our invention, what we claim is 1. In a veneeringmachine a gluing-table having clamping means comprising a strip to enter a groove of a board and the springfingers, substantially as specified.

2. In a veneering-machine, the combination with a bed-plate or table provided with a fulcrum-point on the table adjacent to the front longitudinal side of the mold, with a mold adapted to conform the veneering to a board or molding, a molding-surface at the rear wall of the mold and an upwardly-projecting abutment-rib at said forward side behind which the work may be forced by said lever and securely held.

3. In a veneering-maehine the combination of a bed-plate or table with a mold provided with a tongue adapted to enter the groove of a board and force the veneer therein, a fulcrum-point on the bed-plate ortable adjacent to the place where the material to be veneered is introduced into the mold and a force-bar adapted to force the board into the mold substantially as described.

In testimony that we claim the foregoing as our invention we have signed our names, in presence of two witnesses, this 3d day of March, 1894..
