li ifizesses N. EETERS, FHOTO-LITHOGRAPN early at a ca iber-n Bea-kno n thattLJOSEPH. L. FIRM, of

the city, county and Sta-te of New York, have invented .certainv new; and useful Improvenient's in"Ro'tary Perfecting-Presses; and I do hereby declarethat the following is a full, clear, and exact description of the same, ref: erence being had tojthe f accompanying draw.- ing, which forms part of this specification.

Theinvention has reference to'rotary print-- ing presses, and more. particularly to rotary pertecting-presses- The invention consists, in a certain combination of a transversely-divided paper-supplycylinder or roll, forming two or' more inde-, pendentsupply cylindersor rolls, and serving to feed two or ,more independent webs, side by side, and a single"form-cylinderand single ,irepression-cylinder constructed to simultaneously print saidwebs'as they pass from the supply cylinders or rolls to or between said form. and impressioncylinders. The invention also consists in a combination of one or more single formrcylinders with annular; bearings between duplicate forms can ried' by each of. said cylinders, and oneyor more'single impression-cylinders having like inttllmediate annular bearings for operation, in con binationwith -the intermediate annular bearings of the form-cylinders and lower suppoiting'rollers, whereby the form and impression cylinders, when constructed to print in duplicates or series arranged side by side throughout. the length of said cylinders, are intermediately supported. the one by the other, andare prevented from springing.

Figure .1 represents aplan of a rotary print-- ing-pr'ess in part in accordance'with the invention, and constructed to simultaneously print on both or opposite sides of four independent webs of paper. Fig. 2 is a front or one-end View of the same; Fig. 3, a side View thereof; Fig. 4, a vertical section on the irregular line a; a2, and Fig. 5 a further Vertical section on the line 3 3 Ais a duplicate ibrm-cylinder-that is a cylinder carrying two independent circular forms, f f, arranged side by side in the length Nit W YORK, N.

CASE D.

of said cylinder, but separated by an inter! mediate annular bearing or ring, a. This duplicate form-cylinder is arranged to work in connection with an upper duplicate impression-cylinder, B, and a lower duplicate impression-cylinder, B both of which have their impression-surfaces g g arranged to. correspond with the forms'ot" the cylinder A, and

w the duplicate impression-surfaces of which are separatedby annular bearings or rings .b,,ar-

ranged so that they bear or work in contact v with the intermediate ring or bearing aof the form cylinder A. By, this construction the form and. impression cylinders are supported intermediately of their length, the one bythe other, and prevented from springing or-yield ing sufficiently to interfere with the impression, and are thus held in their .proper positions independently of the boxesin the frame of the press, and the amount of strain that would otherwise fall upon such long cylinders isavoided. A roller, 8, which should be adjustable up. or down, is arranged underthe in termediate hearing I) of the lower impressioncylinder B to give a solid intermediate lower hearing .or rest to said cylinder. Such con struction and intermediate support of the form and impression cylinders allows of an increased-number of impressions being simultaneously made from or by the same cylinders on independent webs, as will be hereinafter more fully explained, and by increasing the number of intermediate bearings a, b and roll er-supports s the number of form and iinpression surfaces, lying side by side throughout the length ofsaid cylinders, may be increased so as to act upon a still greater number of webs simultaneously. At'the opposite end of the press is'a similarly-arranged series of cylinders with duplicate form and impression surfaces f g separated by intermediate bearing-rings a I), also a lower intermediate adjust-able supporting-roller, s, all for. action in relation with each other, as hereinbefore described with reference to the first series of but in this last or opposite series of cylinders the upper and lower cylinders A A are both 2 h i i y 110,542 I I P 1 I;
