Abstract
Abstract Adjusting device for postage metering and value stamping machines for adjusting printing rollers and cylinders which includes type wheels mounted in a printing cylinder having a shaft, each of the type wheels having a respective stepping motor operatively associated therewith for adjusting the respective type wheel by means of a respective toothed rack and a respective double toothed rack, the toothed racks and the stepping motors being disposed radially to the printing-cylinder shaft and the double toothed racks being disposed parallel to one another, a selective printing roller adjustable by one of the double toothed racks via a belt drive, the toothed racks and the double toothed racks being coupled by a hook-connection, one of the respective toothed and double toothed racks having a widened hook-shaped part, the double toothed racks being adjustable beyond a maximally required number of steps of the type wheels, and the ends of the double toothed racks being guidable laterally out of the printing cylinder for actuating respective levers to adjust, in stepwise manner, further printing rollers.

Dependent Claim
172 words
Adjusting device for postage metering and value stamping machines for adjusting printing rollers and cylinders comprising type wheels mounted in a printing cylinder having a shaft, each of said type wheels having a respective stepping motor operatively associated therewith for adjusting the respective type wheel by means of a respective toothed rack and a respective double toothed rack, said toothed racks and said stepping motors being disposed radially to said printing-cylinder shaft and said double toothed racks being disposed parallel to one another, a selective printing roller adjustable by one of said double toothed racks via a belt drive, said toothed racks and said double toothed racks being coupled by a hook-connection, one of the respective toothed and double toothed racks having a widened hook-shaped part, said double toothed racks being adjustable beyond a maximally required number of steps of said type wheels, and the ends of said double toothed racks being guidable laterally out of said printing cylinder for actuating respective levers to adjust, in a stepwise manner, further printing rollers.
Claim 3
Dependent Claim
18 words
Adjusting device according to claim 1 including a plurality of magnets carried by each of said toothed racks.
Claim 4
Dependent Claim
16 words
Adjusting device according to claim 2 including stationary probes for adjusting control disposed opposite said magnets.
Claim 5
Dependent Claim
63 words
Adjusting device according to claim 1 wherein each of said double toothed racks have two opposing rows of teeth, one of said rows of teeth serving for adjustment of individual type wheel and selective printing rollers, and the other of said rows of teeth for alignment, in common, of all of said type wheels and said selective printing roller for the printing process.
Claim 6
Dependent Claim
24 words
Adjusting device according to claim 1 including a locking rod mounted in a slider, said locking rod continuously resiliently engaging said double toothed rack.
Claim 7
Dependent Claim
23 words
Adjusting device according to claim 5 wherein said locking rod is guided, secured against torsion, in a slot formed in said printing-cylinder shaft.
Claim 8
Dependent Claim
49 words
Adjusting device according to claim 5, including a lever mounted in said printing-cylinder shaft and coupled with said slider, and a stationary magnet, said last-mentioned lever being actuatable by said magnet through the intermediary of a plunger for releasing said double toothed racks during adjustment of the type wheels.
Claim 9
Dependent Claim
45 words
Adjusting device according to claim 7 wherein said lever carries a magnet at an end thereof, and including a stationary probe whereon said magnet carried by said lever acts for controlling a normal setting of said printing-cylinder shaft and a setting of said locking rod.
Claim 10
Dependent Claim
43 words
Adjusting device according to claim 1 wherein said stepping motors have pinions and intermediate gear operatively associated therewith, and said printing-cylinder shaft is formed with annular offsets serving as radial tooth locks for said pinions and said intermediate gears during a printing operation.
Claim 11
Dependent Claim
36 words
Adjusting device according to claim 1 wherein said levers actuatable by said double toothed racks are of U-shaped construction and are mounted on the printing cylinder for pivoting about the lateral legs of said U-shaped racks.
