INSTALLATION OF OPTIONAL TRIPPING ATTACHMENT
The following instructions apply to any of Numberall’s bench presses: Models
131, 131A, 133, 136, 136A, and 137.
1. The tripping attachment is shipped assembled but will need adjustment. All
mounting holes in the press have been pre-drilled. The hand clearances
inside the casting are very tight and some patience is required.
CAUTION:
WHEN WORKING WITH THE CASTING, MAKE SURE ALL POWER
SOURCES HAVE BEEN DISCONNECTED.
The tripping attachment is easily
installed if the press is lying on its side.
2. The linkage will attach to the press with the turnbuckle assembly (*-116)
toward the rear. It is located on the right hand side of the frame casting,
bolting to the rocker arm and frame casting.
3. Loosen the two jam nuts on the turnbuckle assembly. One is a left hand
thread and one is a right hand thread.
4. Insert the 1/4” cap screw through the lower ball end and thread it into the 1/4”
hole in the right rear inside of the frame casting.
5. Insert the shoulder screw (*-114) through the tripping arm from the right. Slide
the spacer over the shoulder screw. Start the shoulder screw into the
threaded hold near the back of the rocker arm. Tighten the shoulder screw.
6. Adjust the rear turnbuckle assembly by rotating the center rod until 3/4” of
clearance exists between the tripping arm and the top of the dovetail ram.
Tighten both turnbuckle jam nuts while holding the turnbuckle rod stationary.
7. Tighten the free motion connecting link assembly into the Model 50 Automatic
Numbering Machine. Tighten the jam nut so that the ball end is aligned
vertically.
8. Start the free-motion rod into the free-motion connecting link.
9. By rotating the actuating arms away from the numbering machine, it will be
possible to simultaneously feed the free motion rod into the free motion
linkage and slide the numbering machine into the dovetail ram. Tighten the
marking device clamping screw.
10. After the press has been properly adjusted for the impression depth, cycle
the press. If the numbering machine is not advancing properly, it will be
necessary to screw the free motion rod either in or out of the upper ball end.
Loosen the jam nut first. Adjust the rod until the numbering machine clicks
into its advance position. Make sure the press makes a full cycle. If it does
