MACHINE. FOR MANUFACTURING WOODEN, sroons.

Application filed March 28, 1927. Serial No. 179,143. d

This invention relates to improvements in machines for manufacturing wooden spoons,

and the obj ects of the invention are to pro vide a simply constructed, durable and'efiicient machine of this description that will more satisfactorily and economically per-- form the functions required.

The invention further relates to amachi ne for cutting wooden spoons and other 11'- regular shaped pieces from veneer in such a manner that waste is reduced to a m nimum. c

With these and other objects hereinafter more fully referred toin view, the essential features of the improved machine include the combination with a reciprocating cutting die and a reversible block member and a slidably operable pocket associated with the dieand means for supplying veneer to the die and block, of coordinating and separate mechanisms for operating the die, the pocket and the feeding. block at predeter mined points in the operation of the ma-.

chine. p v 7 Referring now to the drawings, in whlch like numerals of reference indicate corresponding parts in each figure, v

Referring now'more particularly to the drawing, in the improved machine, a preferred example of which is herein disclosed, A indicates the frame in which is turnably mounted, in bearing 10,- a substantially horseshoe frame or casting B, one end of therefrom, a pocket 0 to which a cutting I die12is removably secured. I

A, shown in Figure ,6, the block 11' comprises a bedplate 13 in which is fitted a block 14 ofwood or other suitable material The frame is, as illustrated in Figure 4, substantially T shaped in cross section as indicated at 16 and is adapted to slidably support therein the pocket-member C which is designed to receive the spoons as theyare retained therein by means of screws15 on each side thereof.

lines in Figure 2, I provide feed rollers 18 and 19. the operation of which and the mechanism connected-"therewith is snbse-c quently referred to.

The means for operating the die comprise a rod 20 extending through the pinion 21,

the end of which is pivotallyconnected by means of the connecting rod 22 to the crank 23 formedon the crank shaft'24 mounted transversely of the frame 2.5 in suitable bearings 26 and 27 and protruding at each end beyond said frame. On one of these protruding ends is a drive gear 28 driven'by the gear 29 which'i's operated in any suitthereon, while the opposite end ofthe; shaft reciprocative movementof the rod 31 con-- nected at 32 to the shaft 24. 1 The rod 31 is connected to the sliding carriage 33 mounted in the frame A in turn connected by the rod 34 to arm 35 mounted on the shaft 36 upon which the feed roll 18 is mounted. Thearm 35 is provided with a spring actuated dog 36 -which engages the teeth of the gear 37 which in operation will rotate the shaft 36 and feed roll 18 thereon. Adjacent the end of the shaft 36 is a gear 38. This gear. is adapted to mesh with the gear 39 mounted on the shaft40 which carries the feed roller 19;

It will therefore be seen from the foregoing that at a predetermined point. in the operation of the shaft 24 the rolls 18and 19 will be caused to rotate and feed the veneer D a predetermined distance into the machine We now come to the operation of reversing the pocket and the block to synchronize with the operations already described. This mechanism comprises the bevel gear designed to mesh with a bevel gear 42, (see Figure 3) on a shaft 43 at substantially right angles to the shaft 24 and journalled in suitable bearings rigidly mounted on the main frame. On the opposite end of this shaft is a lever arm 44 to which is connected a rod 45 in turn connected to asegment gear wheel 46 through a pivoted sleeve 47 on each side of which, on the connecting rod 45, are collars- 48 provided with set screws 49 by which means the stroke of the rod may be adjusted.

The segment gear 46 meshes with the pinion 21, so that on the segment gear being rotated through the operation of the rod 45,

'gears 42 andBO, the pinion 27 will be operatedlto reverse the member B and with it pocket C and the block 11 so that the spoons cut out from the veneer will be in the form shown in Figure 8, similar portions of every second spoon being in staggered relationship I to the similar portion of the adjoining spoon, :thus practically eliminating waste of the veneer.

ltwill also be noted thatt-he segmental gear 46 is keyed on the shaft 50 journalled in suitable bearings on the auxiliary supports 51 and 52, and although a segmental gear is here illustrated it will be understood that a To limit the travel of the memberB duringits oscillatory movement, I provide an extension or lip 57 formed integral therewith adapted in'operation to contact with the pad 58 of rubber or similar material secured to the upright 59, (see Figures 1 and 2),

In addition to the feed rolls 18 and 19 1 provide a pair of rollers 60 and (il'suitably supported and adapted to engage the top edge of the veneer as it is fed to the machine and thus keep the feed uniform. The

guides 62 and 63also materially assist in guiding the material to the machine.

- In operation and on the rotation of the crank shaft 24, the rod. 20 with the pocket and cutting die 12 thereon, will travel first outwardly then inwardly. Simultaneously with the latter part of the outward and first part of the inward stroke, the rollers 18 and 19 will be rotated to supply the'strips of veneer D from the source of supply in the form of rolls, between the cutting die 12 and the block 11, the spoons cut out or stamped being delivered to the pocket and so that the next. cut of spoons will be upsidedown as compared to the first out, as illustrated in Figure 8. The reversing movement oft-he rod or shaft 20 is provided for by the universal joint 64..

I Then, as the operation proceeds, upon the forward movement of the rod 20, the pocket C Wlll be again in the positionas shown in Figure 2, and so on.

It will thus be seen that my improved A machine provides for a die, a reversible block opposed to the die, a slidably operable and reversible pocket associated with the die, and coordinating mechanisms for simul taneously operating the die and the pocket and causing the pocket at a predetermined point in its travel to automatically perform one half revolution and simultaneously therewith the block to perform a similar operation. In this way, while simultaneously with thelatter part of the rearward stroke and part of the forward movement of the die and the pocket, mechanism for feeding the material to the die is automatically thrown into gear and operated and automatically thrown .out of gear on the latter part of the forward movement of the'die and the pocket.

The die and block as previously stated co ordinate in movement and operation at the same timev It will be understood that a fixed block and reversing-die can be used with equally effective results.

As many changes could be made in the:
