HENDEY CRANK SHAPER
A crank shaper equipped with a speed gear-box to permit a single-pulley or constant-speed motor drive has been recently introduced on the market by the Hendey Machine Co., Torrington, Conn. Except for the gear-box this machine is of the same general design as the cone-pulley shaper previously described in Machinery. Eight strokes ranging in geometrical progression from 6 to 102 per minute are obtainable, four of these speeds being secured through the gear-box, and four by means of back-gears. The speed box gears run in oil and the driving and gear shafts in ball bearings. The gears of the gear-box are shifted by the manipulation of a ball handle lever about H-slots in the gear-box cover. The speed gears are made of alloy steel and are heat-treated. The length of ram stroke may be varied from 2 to 24 inches.
The driving pulley transmits power to the machine through a patented clutch which also serves as a brake when moved in the opposite direction to that in which it is shifted for driving. This clutch is controlled by the long horizontal lever which extends to the front of the machine on the right-hand side. The lever has a short movement which provides a quick starting and stopping feature to the ram that is especially of value in setting tools and taking measurements. The lever control also simplifies the meshing of the back-gears and the manipulation of the gear-box lever.
All adjustments of the patented cross-feed mechanism are obtained at the end of the cross-rail. The amount of feed can be varied while the machine is in motion, a dial indicator showing the amount of feed. The feed can be started, stopped, or reversed while the machine is in operation. The feeding movement takes place on the reverse stroke of the machine. The cross-feed screw is provided with a dial graduated in thousandths of an inch. The machine may be furnished with or without a power down-feed by means of which the machine may be fed at any rate from 0.005 to 0.060 inch per stroke, in increments of 0.005 inch. The machine is set for the different rates of feed by means of a graduated dial. Some of the important specifications of the machine are as follows: Horizontal table travel, 30 inches, vertical table travel, 14¾ inches; minimum distance from ram to table, 4 inches; dimensions of table top, 17 by 24 inches or 17 by 42 inches when equipped with an extension as illustrated; dimensions of table side, 17½ by 18 inches; and approximate weight of machine, 5700 pounds. |
