New Profile Machine
The illustration on the opposite page represents a new profile or edging machine, also made by E. E. Garvin & Co. This machine is for milling the edges, inside and out, of metal forgings or castings of irregular shapes to an exact size and shape of any pattern required. The pattern or former is secured to the sliding bed, which has a forward and back motion, operated and controlled by the hand crank at the side of the machine. The top, or cross slide, which holds cutter spindle and moves at right angles with the bed, is operated by the hand lever in front. This cross slide also has a pin which is brought to bear against the pattern or former, and the four motions to the two slides will allow the pin to follow around any pattern secured to the lower table or sliding bed. The work to be cut into shape is also secured by suitable fastenings to the lower table, and as the pin passes around the pattern, so the cutter spindle will pass around the piece of work and describe the same outline and dimension as the pattern used. By using a cutler with teeth on the lower end, good surface milling is nicely and quickly done. An attachment is made for cutting small gearing for clocks, registers, telegraph instruments, etc. |
