COMBINED SAWING, BORING AND CHAMFERING MACHINE
The machine illustrated on this page has been designed especially for wagon-makers. It is a small, compact machine, carrying a 12-inch circular saw, and having loose and tight pulleys for starting or stopping the entire machine, and friction clutches for running the saw or the chamfering cutter independently.
The saw, the chamfering cutter and the boring bit are all carried on separate arbors, running at proper speeds and not interfering with each other. None of them need to be removed to make room for the others, but when it is desired to cut grooves, the circular saw can be replaced by a dado head. The table is hinged at the back and arranged to swing up and down by means of a screw, to give the saw or the dado head any desired depth of cut. When so ordered, this table can be made to slide sideways also, against adjustable stops; this enables two holes to be bored at a predetermined distance apart without removing the work from the table.
The chamfering is done by an independent cutter, which can be set to cut any width up to one inch. All bearings and loose pulleys are selfoiling; bearing caps are planed in, lined with the best babbitt metal, and provided with back-pressure screws. The machine is self-contained on a box-shaped body made in one piece, and not liable to twist out of shape when placed on a weak or uneven floor. A belt shifter is provided that will catch the belt in any direction from which it may come. The weight of the machine is about 700 pounds. Floor space required, 5 X3 feet 2 inches. The tight and loose pulleys are 8 inches diameter for a 3-inch belt, and should make about 765 turns per minute.
The manufacturer of this machine is P. Pryibil, of 521?533 West Forty-first street, New York city. |
