Claim 1
Independent Claim
72 words
A machine for disassembling nailed wooden pallets comprising a base frame, nail cutting means, an elongated support for said cutting means mounted at one end on said base frame, a support for a pallet, means for causing relative movement of said supports to bring a pallet on the pallet support into nail cutting engagement with the cutting means and to effect cutting of the nails by continued relative movement of said supports.
Claim 2
Dependent Claim
72 words
A machine for disassembling nailed wooden pallets comprising a base frame, nail cutting means, an elongated support for said cutting means mounted at one end on said base frame, a support for a pallet, means for causing relative movement of said supports to bring a pallet on the pallet support into nail cutting engagement with the cutting means and to effect cutting of the nails by continued relative movement of said supports.
Claim 3
Dependent Claim
72 words
A machine for disassembling nailed wooden pallets comprising a base frame, nail cutting means, an elongated support for said cutting means mounted at one end on said base frame, a support for a pallet, means for causing relative movement of said supports to bring a pallet on the pallet support into nail cutting engagement with the cutting means and to effect cutting of the nails by continued relative movement of said supports.
Claim 4
Dependent Claim
72 words
A machine for disassembling nailed wooden pallets comprising a base frame, nail cutting means, an elongated support for said cutting means mounted at one end on said base frame, a support for a pallet, means for causing relative movement of said supports to bring a pallet on the pallet support into nail cutting engagement with the cutting means and to effect cutting of the nails by continued relative movement of said supports.
Claim 5
Dependent Claim
