This machine has three spindles, operated by the handles connected with the weighted levers at the top, and driven by one belt from a counter-shaft at the back of the machine. By a heavy weight, in connection with adjusting friction pulleys, the belt remains at the same tension, whatever the position of the bits. The middle spindle has a larger pulley than the other two, for slower speed to work the larger bits. Seventeen bits are furnished, varying from 3/8 to 2 inches, all above 1 3/8 to work in the middle spindle. The bits have a horizontal adjustment of 15 inches, and vertical throw of 16 inches. The bed upon which the timber rests is furnished with four rollers, which can be operated by the hand-wheel, or by the lever which operates the friction power feed attachment from the counter-shaft. The counter is attached to the base of the column, and is furnished with tight and loose pulleys, 10 inch diameter and 5 inch face, which should be speeded to 275 revolutions per minute. |
