The particular aim of the invention is to provide a simple and efficient apparatus for this purpose by which Work can be produced with great rapidity and by which the same is done under the full inspection and control of the operator.

Claims:

1. In a wood-working machine, the combination of a moving table, a reversing clutch therefor, means for operating said reversing clutch, a catch rod slidably mounted and adapted to move into position to prevent the reversing of the clutch, a link pivoted to said catch rod, a shaft, a sliding rod connected with said shaft to be operated thereby, said rod having a slot, said link being pivotally connected with said rod through said slot, a handle on said shaft for operating it, and a cam on the work table for engaging said link and moving the catch rod out of operative position.

3. In a wood-working machine, the combination of a frame, a set of vertically movable supports thereon, boxes pivotally mounted in said supports, cutter shafts journaled in said boxes, a work table, a cam for vertically moving said supports, a shaft on which said cam is located, a rod connected with said supports, a guide for said rod supported by said shaft, and a spring located between said guide and the end of said rod for drawing the support onto the cam.

4. In a wood-working machine, the combination of a frame, a set of movable supports thereon, a cutter shaft supported by said supports, a work table movable under said cutter shaft, a cam shaft, a cam thereon, a guide on the cam shaft, a rod passing through said guide and connected with said supports, and a spring on said rod for forcing the supports toward the cam.

5. In a wood-working machine, the combination of a bodily movable cutter, a work table movable thereunder, means for raising the cutter, a pin moving with said means, a rod adapted to support the cutter when the cutter is not supported by said means for raising it and located in a position to be engaged by said pin, and means adapted to be operated by said rod for stopping the machine.

6. In a machine for making seats, the combination of a cutter, a reciprocating worktable, a cam for moving the cutter While the work-table is on its forward stroke, and means for supporting the cutter out of connection with the cam during the return stroke.

7 In a machine for making seats, the combination of a cutter, a reciprocating worktable, a cam, a projection or roller engaged by the cam to move the cutter while the Work is being presented thereto, and means for supporting the cutter to hold the projection or cam-roller out of engagement with its cam during the return stroke of the table.

8. In a machine for making seats, the combination of a cutter, a reciprocating Worktable, cams, projections or cam-rolls supported by said cams for moving the cutter While the work is being presented thereto, a reversing handle, and connections operated therefrom for reversing the travel of the carriage, and supporting rods engaging the projections or cam-rolls and holding the same out of engagement with their cams during the return movement of the bed.

9. In a machine for making seats, the combination of a cutter, a reciprocating Worktable, cams turning in one direction While the table is on its forward stroke, and in the other direction While the table is on the return stroke, said cams serving to move the rock shaft and adapted to hold the cutter elevated during part of the stroke of the Work table, and means connected With the cutter raising and lowering device for moving the said rod to rock the shaft and stop the motion.

11. In a wood working machine, the combination of a bodily movable cutter, a work table movable thereunder, a cam, means operable by said cam for raising the cutter, a pin on the cam, a sliding rod adapted to support the cutter when the cutter is not supported by the cam and located in a position to be engaged by said pin, and means operable by said rod for stopping the motion.
