Abstract: 560,159. Cutting up wood. LAWRENCE, B. Sept. 18, 1942, No. 13184. [Class 145 (i)] A machine for making wood wool comprises two hoppers arranged side by side and each open on one side, a platen in each hopper, means for raising and lowering each platen independently of the other, and a single knife carrier mounted to reciprocate horizontally over the tops of the hoppers. The end walls of the hoppers are formed by the vertical frame members 11, 12, 111, 112 of the machine, the backs are closed by a wall 13, but the fronts of the hoppers are open to permit insertion of the wood. The knife carrier 16 reciprocates on rails 14, 15 above the hoppers, and is provided with knives 17 so arranged that cutting takes place in both directions. The carrier is connected to a pivoted lever 21 which is oscillated by a crank disc 25, and the lever also reciprocates a bar 55 which operates ratchet -and-pawl mechanism that rotates screwed shafts 38 to raise the platens 32 slowly in the hoppers. The weight of each platen is balanced by weights attached to cables 35, and the platen can be raised or lowered by hand by a lever 48 after it has been disconnected from the shaft 38 by means of a handle 47. The platen is also disconnected from the shaft, when it reaches its highest position, by a lever 64 which is rocked by a spring 69 when a projection 76 on a platen trips a latch 73. A handle 72 enables the latch to be tripped at any time to stop the upward feed of the platen. Each hopper is provided with a plate pivoted to one side of the hopper, which is connected to a counterweight 83 and clamps the wood on the platen against the other side of the hopper. The wood is also clamped against the rear wall 13 by massive arms 84 which are pivoted on a shaft 85 and are connected to a weighted lever 89. A hood 92, supported above the knife carrier 16, directs the wood wool to the rear of the machine.
