The 28-in. square planer, shown herewith, is one size built by the New Haven Manufacturing Company, New Haven, Conn. The machine will plane 6 and 8 ft. (inside the pockets), 28 ins wide, 28 ins. high. It is driven by two belts, the main driving shaft having tight and loose pulley attached to it on each side of the machine, giving a very steady driving motion. The bed is very deep, wide and strongly braced, supported by cabinets. Center legs are furnished on both lengths of bed. The head has automatic power feeds in all directions (cross, vertical and angular), the crossbar is deep and strongly braced, and can be quickly raised or lowered by power by means of a friction clutch on the driving shaft (as shown in cut.) The cross-feed screw is cut with double threads, giving rapid adjustment; the bronze cross-feed nut can be taken out (when necessary to renew it) without removing the saddle from the cross-bar.
The tool head can be adjusted in any direction without disturbing the feed pawl; the table can be run back to examine work without changing the position of the dogs, and the feed can be quickly changed from nothing to very coarse without stopping the planer. The three T-slots in the table are planned out and the holes drilled.
All sliding surfaces are scraped. All racks and gears are cut from the solid blanks, driving shafts and screws are of steel, with nuts casehardened. All gearing is on short shafts within the bed, running in cap boxes and protected from chips and dirt. The V's of bed and table are lubricated by means of three sets of friction rolls, running in oil pockets in the bed.
Driving pulleys on counter-shaft are 12 ins. diameter, 4-ins, face, and should run 12¼ revolutions to give a table movement of one foot per minute. Counter-shaft belt should run open. |
