No. 5 Large
Patent Universal Wood-Worker and Molder.
Molder Side.
"With Four-Side Molder, and Simultaneous and Independent Adjustable Tables.
Tlie engraving on the preceding page represents the molding side of ourNo. 5 Universal Wood-Worker and Molder, described on page 106. It is a com-bination of two machines, a Heavy Four-Side Molder and the No. 2 Variety Wood-Worker, forming a double machine, one on which two operators may work,starting and stopping either side of the machine without regard to the other.
The work is fed under and between revolving cutter-heads, and has, in con-junction with the wood-worker side, so many applications and combinationsand will perform such a great variety of work that it is called “ Universal.” Onthe wood-worker side it will dress out of wind and surface by feeding the mate-rial by hand over revolving cutters acting between two adjustable tables, andit will reduce to a perfect thickness and square up on all four sides on themolder side, the material being'fed under and through the cutters by feed-rolls.
The frame is especially heavy. The main arbor, as well as the side and lowerliead-arbors, are of large diameter, lead-ground, run in self-oiling bearings linedwith the choicest grades of metal and scraped to perfect bearings. The headsare steel slotted on all four sides. The top and bottom heads are made to workeither 8", 9", or 10" wide, as may be ordered. The side heads and arbors rise andfall with the molder-bed. They are constructed so the pull of the belts coniesagainst the solid hanger, and not against the caps. The bed is gibbed to the column,and raised by hand-wheel and screw at the front.
The feed consists of two large upper feeding rollers, mounted in swingingarms; also two large rollers in the bed. These are all driven by a train ofpowerful gearing. The upper feed-rollers are weighted, and can be raised fromthe material to allow it to be withdrawn from the cutters. The side heads canbe set to varying angles, and are adjustable from the working side of the machine.
The under cutter-head has an end adjustment, a vertical adjustment withthe bed, and also independently of it to suit the cut. The end of the table be-yond the lower head can be dropped down for access to the cutters. There aremovable throats for reducing the size of the opening of the lower and insideheads. The outside bearing of the top cutter-head is supported on a columnextending to the floor, and is quickly removable for changing heads.
This machine will surface on both sides, and with proper heads tongue and 1groove flooring and ceiling up to 8", 9", or 10" wide. Both sides of this machinehave independent main arbors and outside bearing supports, and each side is belteddirect from the countershaft, which is arranged to convey power simultaneouslyor separately to each side. This molding side is the same capacity and range ofwork as the machine on page 76.
The tight and loose pulleys are 12"x6", and should make 900 revolutions.
