A NEW ELECTRICALLY DRIVEN MILLING MACHINE.
We illustrate a recent design of milling machine by the Hendey Machine Company, who are represented in England by Messrs. Charles Neat and Co., of Queen Victoria Street, E.C. The Hendey-Norton box of feed gears is well known, having been very flatteringly and widely imitated since its introduction about ten years ago. It has been applied to other types of machines, as well as lathes, for which it was originally designed. The special feature, however, to which attention is now called, is the motor drive. The motor is placed over the head, where it is carried on a sliding bracket which provides the means by which the belt is slackened and re-tightened when shifting it from one step of the cones to another. This is operated by a cam shaft and lever, the latter being seen under the starting box. The change is effected quickly, and the bracket is securely locked in place.
The driving of the machine is done by spur gears first, seen at the extreme top left hand. These are driven alternatively by two raw hide pinions of different diameters on the armature shaft of the motor. The larger wheels run freely on the shaft, and either one is driven by its pinion through a friction clutch—driving on their interior surfaces like friction pulleys, a device already familiar on the Hendey pillar shapers. Engagement is through the medium of the shipper rod moving through the hollow back gear shaft, and operated by the lever seen in front of the bracket. |
