Recommendations
We recommend that shops that work lighter iron, such as is used on smaller pipes and fittings employ
5/16” Pittsburgh Lock Rolls mounted on the extended shafts of this machine. If production warrants, our
smaller machine (Lockforrner 22”) should be installed.
The reason for this recommendation is as follows:
As most hand brakes cannot be used to form a single edge smaller than 3/8” on heavy iron our
Lockforrner = 16 rolls a 1/2” pocket with the permanent rolls.
The lighter iron can be worked in the permanent rolls but the closing down of the lock over the 1/2” span
causes distortion of the material.
We, therefore, suggest that you use the 5/16” Pittsburgh Lock auxiliary rolls on 22 gauge to 28 gauge
iron. These rolls may be installed or changed in about 20 minutes by an experienced operator and the
lock resulting is much more accurate and neat,
Operating Instructions
VERY I M PORT AN T ! TO SET THE CALIBRATED DIAL FOR 16 AND 18 GAUGE, TURN DIAL (RIGHT
HAND THREAD) DOWN TO THE BOTTOM WITH THE LETTER “S” IN LINE WITH THE ARROW
MARKED ON COVER OF MACHINE. THEN RELEASE TO SETTING OF MATERIAL TO BE USED.
THE CALIBRATED DIAL: The purpose of this dial is to regulate the width (not the depth) of the pocket.
For example, when forming 16-gauge metal, the pocket must be wide enough to take the 16-gauge single
edge which fits into it; and should become narrower correspondingly, for lighter gauges. This is done by
setting the dial to whatever gauge you are running through the machine.
Should the dial get out of adjustment, re-set by:
(1) loosening the set screw,
(2) turning the stud all the way down,
(3) setting the “S” mark on the dial opposite the pointer on the cover.
Example:
If the dial is set for 16 ga. the lock is wide,
3-1/16 far from rolls.
When set for 24 ga. it becomes narrow, 3
closer from rolls
