This machine is of the same series as our Nos. 3, 4J», and 5 Molders, designedto work 7" in width. It is the heaviest seven-inch niolder made. It has large,steel arbors, lead-ground, long, self-oiling bearings, and strong feed. The counter-shaft is placed so as to secure long belts. It will be found a most valuable molderfor all classes of work within its capacity.
The main and side head-arbors are l T y' diameter where heads are received.The main arbor is provided with an outside bearing for supporting the outerend, and is mounted on an upright column extending to the floor so that thebed can be raised or lowered to any position without danger of the arborspringing. This outside bearing is readily removed for substituting differentheads.
The heads are of steel, and slotted on all four sides for using cutters withirregular slots. The side and under heads rise and fall with the bed, and alsohave an independent vertical adjustment to suit different work. The side headscan be set to varying angles, and are adjustable across the bed while in motion,from the working side of machine.
The bed is gibbed to the frame, and raised and lowered by a hand-wheel atthe side, in a convenient position to the operator, and where he is free from dangerof contact with the cutters. It has a lock attachment for holding securely inposition. Also adjustable mouth-pieces fitted to the bed for reducing the sizeof the opening around the head for special work. The bed will lower to receivestuff up to 14".
The feed consists of two sectional feed-rolls above, and two smooth rollers inthe bed, all connected and driven by a train of expansion gearing. The upperrolls are hung in swinging frames, raise parallel with the work, and can bereadily lifted to stop the feed, or allow material to be withdrawn without stop-ping the machine. It has four speeds of feed, viz., 19', 26', 31', and 43' per minute.
The pressure-bar and bonnet are combined, and can be swung entirely awayfrom the upper head, permitting ready access to the cutters. Full sets of wrenches,springs, pressure-blocks, etc., are sent with each machine.
The tight and loose pulleys are lo"x5", and should make 900 revolutions.
