Claims
- 1. A method of making a block comprising the steps of:raising a press foot within a breech to a first level even with an open upper end of the breech; moving a feed drawer having an open lower end and filled with granular material laterally across a planar surface into registration over the breech; lowering the press foot to a second level in the breech to receive a volume of the granular material from the feed drawer into the breech; withdrawing the feed drawer laterally across the planar surface out of registration with the breech to remove excess granular material from above the open upper end of the breech; lowering a bucking foot to close the upper end of the breech; raising the press foot to a third level within the breech to compress the granular material in the breech into a block; and raising the bucking foot to a level higher than the top of the feed drawer and the block to permit ejection of the block from the open upper end of the breech into a path of the feed drawer.
- 2. A method according to claim 1:said step of raising the press foot to the first level simultaneously inserting a previously-made block into a path of the feed drawer; and said step of moving the feed drawer laterally into registration over the breech simultaneously pushing the previously-made block out of a path of the bucking foot.
- 3. A method of making a block comprising the steps of:raising a press foot within a breech to a first level even with an open upper end of the breech; moving a feed drawer having open upper and lower ends and filled with granular material laterally across a planar surface into registration over the breech; lowering the press foot to a second level in the breech to receive a volume of the granular material from the feed drawer into the breech; withdrawing the feed drawer laterally across the planar surface out of registration with the breech to remove excess granular material from above the open upper end of the breech and to align the feed drawer under a hopper storing granular material; dispensing additional granular material from the hopper to refill the feed drawer; lowering a bucking foot to close the upper end of the breech; raising the press foot to a third level within the breech to compress the granular material in the breech into a block; and raising the bucking foot to a level higher than the top of the feed drawer and the block to permit ejection of the block from the open upper end of the breech into a path of the feed drawer.
- 4. A method according to claim 3:said step of raising the press foot to the first level simultaneously inserting a previously-made block into a path of the feed drawer; and said step of moving the feed drawer laterally into registration over the breech simultaneously pushing the previously-made block out of a path of the bucking foot.
- 5. A method of making a vertically and laterally tongue-and-groove block comprising the steps of:raising a press foot having a three dimensional upper surface within a breech having complementary three dimensional opposite side surfaces to a first level even with an open upper end of the breech; moving a feed drawer having open upper and lower ends and filled with granular material laterally across a planar surface into registration over the breech; lowering the press foot to a second level in the breech to receive a volume of the granular material from the feed drawer into the breech; withdrawing the feed drawer laterally across the planar surface out of registration with the breech to remove excess granular material from above the open upper end of the breech and to align the feed drawer under a hopper storing granular material; dispensing additional granular material from the hopper to refill the feed drawer; lowering a bucking foot having a three dimensional lower surface complementary to the upper surface of the press foot to close the upper end of the breech; raising the press foot to a third level within the breech to compress the granular material in the breech into a block; and raising the bucking foot to a level higher than the top of the feed drawer and the block to permit ejection of the block from the open upper end of the breech into a path of the feed drawer.
- 6. A method according to claim 5:said step of raising the press foot to the first level simultaneously inserting a previously-made block into a path of the feed drawer; and said step of moving the feed drawer laterally into registration over the breech simultaneously pushing the previously-made block out of a path of the bucking foot.
- 7. A method according to claim 6, said step of moving the feed drawer and simultaneously pushing the previously-made block being performed by abutment of a three dimensional face of the previously-made block with a leading face of the feed drawer.
- 8. A method of making a vertically and laterally tongue-and-groove block comprising the steps of:raising a press foot having a three dimensional upper surface within a breech having complementary three dimensional opposite side surfaces to a first level even with an open upper end of the breech; moving a feed drawer having open upper and lower ends and filled with granular material laterally across a planar surface into registration over the breech; lowering the press foot to a second level in the breech to receive a volume of the granular material from the feed drawer into the breech; withdrawing the feed drawer laterally across the planar surface out of registration with the breech to remove excess granular material from above the open upper end of the breech; lowering a bucking foot having a three dimensional lower surface complementary to the upper surface of the press foot to close the upper end of the breech; raising the press foot to a third level within the breech to compress the granular material in the breech into a block; and raising the bucking foot to a level higher than the top of the feed drawer and the block to permit ejection of the block from the open upper end of the breech into a path of the feed drawer.
- 9. A method according to claim 8:said step of raising the press foot to the first level simultaneously inserting a previously-made block into a path of the feed drawer; and said step of moving the feed drawer laterally into registration over the breech simultaneously pushing the previously-made block out of a path of the bucking foot.
- 10. A method according to claim 9, said step of moving the feed drawer and simultaneously pushing the previously-made block being performed by abutment of a three dimensional face of the previously-made block with a leading face of the feed drawer.
