To all whom. it may concern.'

Be, it linownthat l, ViLLiAM (l. HUEBNER, a citizen of the United States, residing at Buffalo. in the county of Erie and N ew York, have invented a ting Machines, which the following is :i specification. This invention relates to oli'set printing machines for producing prints from a primary printing surface in a 'desired loczition, position or arrangement oii :i secondary printingy surface, proof sheet or other printreceiving surface. n

Machines embodying the invention :ire especially adapted for producing serondary printing surfaces on which prints from several difi'eient kinds of primary printing surfaces. such, for example. as Wood cuts. copper plates, steel engravings, drawing-z on stone. type. :ind lithographiey engravings. are assembled in a desired arrangementor Af rrcupingl: also for printing :i plurality of dupliczite in'ipressions in prescriheth locfitions` and pf'isitions on a secondary println,"r :.ui'f'aw. or other print-receiving surface; :und vfor 'building up designs on printing' surfa -e-. or other 4-iur 'z 'f s. hy rcpeutiiipy there` on in difi'ei'ent required loeation.-4 and positions. ii.-ipression.- from ii design unit on :i primary printing surface.

The scale r has divisions cach representing one inch (or other `unit; of measure) of transverse movement of thc supplemental offset cylinder, and the other seais 1 hns divisions representing small fractions, for instance, hundredths, of the inches .or units indicated by the first scale. The wheels r r ore geared to the-operating crank shaft for the adjusting screw Q3 so that the units Wheel r2 turns a'distance equal to one of the inch or unit divisions of the scale 1"S during a corresponding transverse movement of the offset cylinder, while the other, or fractions, wheel r turns a corn- 50 in different rlocationsor i, rooms plete mvolutin'dur' .such movement of the offset cylinder an units wheel. The gearing for .this purpose comprises a pinion f'splmed on the crank shaft q and meshing with a gear wheel a which loose on the axles on which the index wheels r and r* are Journaled and drives a pinion e on a shaft .at This shaft is connected by bevel gears e s to a worm shaft s', and by bevel gears e s' to a worm sluit e1". The worm si and el are provided with worms which respectively drive .the index wheels 1f and r. gears are operly proporhoned to give the required ierentia-l speed oi the index wheels r and r. Thus the transverse position of the oset der in inches ,and small fractions there is shown wgetliostls vof the indexes or points on randmAandlzhecylmdercan be adgmted .quickly with great exactness.

I n the use of the machine, the main offset oyllnder E is used when a large subject is 30 te be reproduced or only a simple adjust ment is required. The drive mechanism, for the cylinder is set in operation and when the cylinder reaches a suitable point over the primary support B, the lever K is operated to lower the cylinder intol contact with the primary printlng surface C. When the cylinder has rolled over the subject it again raised by operating the lever K. The cylinder can then be adjusted circumferentlally relative to its propelling wheels f3, if this is necessary to place the print in a particular location on the print-receiving Surface C. yThe drive mechanism is again n started and the cylinder lowered into and raised out of Contact with the rintreceiving surface at the proper points by means of the lever K, as aboveexp a'ined.V

censtmion ple could he When it is desired to reproduce a smally subject, or to make duplica e prints thereof osltions on the print-receiving surface, the supplemental yoil'set cylinder O is used. and if the adjustment requires it, the 'primary printing surface C is secured on the adjustable holder L. 5 After the supplemental cylinder has been operated in the same manner. as the mam cylinderto take the impression from the primary printing surface, 1t can be adjusted either .circmnferential'ly or axially, or bpth, as required to place the print in vthe required position on the printrece1v1ng surface. By appro 'alte adjustments ofthe supplemental set cylinder, or of the holder L, or

both, successive impressions from the pri .Cylinders over faces in predetermined mary printing surface .un be placed in any desired arrangement or oupinfr on the prmt-receiving surface. vFlic different described sdjustments of the parts enables a u'actualy unlimited variation of .the possible arrngwlmts or groupings of the prints on the prmreceiving surface.

While the preferred construction of the several parte of the machine has been described in detail; the invention is not limit ed to tbedeecribed construction of thas parts nor to Athe particular means recited for producing the described adjustments or movements .of the supports. the mais and pplemental oset cylinders, the taie'or.

. er for `theprunary printin surface, and the supporting track or Ifname for the cylinder carriage, and for propellin the Meet vthe printing an -print-re ceivmg surfaces.

The ,invention in its broader aspects relates the described or animation and cooperation kolf the parts Wgereby .the subjects .can be tr; asiel-red from the primary print lng ,surface for surfaces to ,the lsecondary planting .or prlnbreceiving surface or surleoetions or posiarticular construe tions, rather lthan to the 'ties employed for tion o i the instrumenta @Keating this result.
