SPACEBAND LEVER
Reading edition
The spaceband lever gets its motion from the transfer lever, through a turnbuckle which connects the transfer lever and the spaceband lever. The purpose of this form of coupling, so threaded that when connecting the two levers it may be turned to regulate the length of the connected parts, is to adjust the spaceband lever so the spaceband lever pawl will pass the highest point of the spaceband box rails, properly bringing the spacebands into the box.
Before making the spaceband lever adjustment, make sure that the transfer slide finger is properly adjusted. Then place the machine in normal position.
Adjust the turnbuckle so the hook of the pawl passes to the right of the highest point of the spaceband box rails not more than 1/16 of an inch. If there is too much space between the end of the pawl and the latch on the spaceband box, which is used as a lock, when recasting 30 ems the slide finger would move to the right against the line and force the matrix from the inner end of the first elevator before the pawl would come in contact with the latch. If the slide adjustments are properly made, the turning of the turnbuckle will have no effect in the adjustment of the slide finger.
Spaceband Lever Pawl
The spaceband pawl is fastened to the spaceband lever by a pivot pin and held in place by a bushing, which fits over the pin. The screw which clamps the bushing to the pin extends downward through the top of the lever. The pawl pulls the spacebands back into the box after the transfer. The pawl should ride freely in the transfer channel, its bearing being a pin screwed into the back side of the pawl. This pin rides on the top of the transfer channel. The sidewise adjustment of the pawl is made by loosening the screw in the top of the transfer lever and allowing the machine to turn over for a few lines, the pawl thus seating itself. The spaceband pawl is held down on the transfer channel by a small spring. The tension of this spring should be strong enough to hold the spacebands from slipping from under the pawl.
