SHAPING MACHINES, METAL. The Hendey Traverse Skaper.—Fig. 1 shows a heavy shaper built by the Hendey Ma chine Co., Tor rington. Conn., and designed for railroad and other heavy work. It has a stroke of 30 in., and can be set to vary length of stroke while in motion. The sad dle has a traverse on the bed of 72 in, Feed works at each end move the saddle back and forth, The saddle can be run fast by hand from one end to the other when desired to change the position on bed, each turn of crank moving it 2,4 in. The head has automatic vertical feed, and can be set to any angle. The circular arbor also has independent feed, and is operated from the pulley end of the machine. The tables are raised and lowered by screws, and the aprons on which the tables work are moved on bed by a rack and pinion. The aprons have a bearing low down on the bed, to insure solidity when taking a heavy cut. The vise jaws open 15 in., and are 15 in. long. The vise is graduated, and swivels on a heavy base-plate.
Wright's Friction Shaper.—Fig. 2 shows a new form of shaper made by J. D. Wright & Sons, Brooklyn, N. Y. The driving shaft seen on the side of the machine carries two loose pulleys ; the forward one is the cutting pulley and has two steps, giving two speeds in cutting, and carries an open belt. The rear pulley is the return pulley, and carries a cross belt from a large pulley on the countershaft. giving a quick return. These pulleys are thrown into and out of gear by a friction clutch. The side bearings for the shaft are adjustable for wear, and have wicks drawing oil from the cup beneath. The worm runs in oil. Tt is of steel, hard
ened and polished, and meshes in the large phosphor-bronze wheel. The wheel is secured to the end of the rack shaft. passing through the base of the machine. to which are secured the two rack wheels. The teeth of the rack are at an angle to the line of the shaft, and are right and left, preventing any side thrust. The loose pulleys on the driving-shaft are turned on the inside of their rims to a taper. The outside of the friction-rims is turned to the same taper, and in action is forced into the loose pulleys by a shifting-fork. The shank of the fork has a certain amount of spring, which relieves the friction and pulleys from the shock or jar of the rain when reversing its motion. The cross-feed is given to the table by the screw ratchet and rod which is secured to the lower part of the disk, which disk is compressed between leather disks. The friction of the leather causes the feed-disk to move with the wheel until stopped by the fixed pin on the rear bracket, or by the adjustable threaded stop pin on the forward bracket. The table is secured to the cross-head in the usual manner, but the top plate is hinged at the rear end of the open table, and is raised by the screw shown, and is clamped when in position by screws passing through slots in the drop pieces shown on the under side of the plate.
