Model 83H and 83P Numbering Head

The Model 83 is ideal for the marking of identification numbers and letters. Its quick-change wheels offer the fastest setup possible for semi-automatic identification marking equipment. Of course, its features are best put to use when the character sequence requires frequent, random changes.


By rotating the selector knobs to the desired wheel number, sliding the wheel shaft to contact the selector knob, and then turning the knurled knobs to rotate the wheel shaft, the proper characters are selected for the marking sequence. All wheels are indexed for direct sight reading. The operator views the sequence being marked between the two arrows on the front frame surface. This direct sight indexing results in less errors and downtime caused in determining the characters being marked.

Construction & Parts
The innovative design of the machine guarantees consistently uniform character alignment and depth of impression. Multiple wheels are held precisely in position by retaining pawls and retaining pawl springs. A retaining pawl seats the index plate on each of the one piece wheels. This one-piece construction assures more accurate stamping than those with two-piece wheels. A pawl block further aids in maintaining wheel alignment. The wheels are engraved for accuracy, strength and alignment. Crafted from high grade tool steel, they are precision heat treated for severe usage and long life. Unlike less rugged designs of other manufacturers, we optimize our frame designs to be compatible with the number of wheels desired by increasing the frame and leg widths. All 5/32″ – 1/4″ machines are constructed using larger diameter wheels, wheel shafts and frames. Hand shank frames are constructed of heat-treated high-alloy steel to resist chipping. The hand shank is vinyl coated to absorb shock during the marking operation when it is struck with a hammer.

The Model 83 can be adapted to virtually any press. Our standard shank is 1″ x 1-1/4″ or 1” x 2.” We offer a standard dovetail shank to fit our hand and power presses or Model 116 Dovetail Adapter. We can make custom round or rectangular shanks. We can omit the shank and provide tapped mounting holes or install a custom designed adapter. We also can leave the top flat so the customer can drill and tap or mount an adapter.
