APPARATUS FOR PRINTING FROM EMBOSSE SHEETS.

SPECIFICATION forming part of Lettere Patent No. 654,268, dated July 24, 1900.

Application led November 8,1898. Serial No. 695,828. (No model.)

To all whom it may concern.-

Be it known that I, BERTI` MILLISON, a citizen of the United States, residing in the borough of Brooklyn, city of New York, State of New York, have invented certain new and usefullmprovements in Apparatus for Printing from Embossed Sheets, of which the following is a specification, reference being had to the accompanying drawings, forming a ro part hereof.

In another application tiled concurrently herewith and serially numbered 695,829 there is set forth an improvement in the art of printing which involves the production of an I5 embossed printing-sheet of paper or other like material from which the desired copies are :made by first inking the raised portions of the printing-sheet and then bringing' such raised and inked portions in contact with the t 2o paper to be printed upon. The printing-sheet so formed must obviously be treated differently, particularly as regards pressure thereon, from ordinary type or stereotype-plates,

especially if many copies are to be obtained from the original printing-sheet.

It is the object of the present invention to produce a machine for printing from such sheets which shall give satisfactory results as regards legibility of the printed copy, shall 3o make it possible to print many copies from a single printing-sheet Without destroying the clearness thereof, and shall make it possible also to secure such copies with great rapidity. Such a machine is represented in an approved and practical form in the accompanying drawings, to which reference will be made in order that the nature of the invention may be clearly understood. i

In the drawings, Figure l is a view in side 4o elevation of a machine which embodies the invention, the receiving-tray being broken off to save space. Fig. 2 is a front end elevation of the same, the receiving-tray being wholly removed.

As represented in the drawings, themachine comprises a printing roll or platen A,

an inking-roll B, a carrier-roll C, and a feedroll D, all mounted in suitable bearings supported by a standard or framework E.

The roll A is of uniform diameter for the greater portion of its length, but at its ends are narrow portions or bands a ct, vformed on or applied to the body of the roll,` of slightlygreater diameter than the main portion of the roll. The object of these bands or portions of increased diameter is to receive lthe pressure of the cooperating rolls and to form between them a shallow recess to receive the embossed printing-sheet A', the depth of therecess being such that the raised portionsof the 6o sheet shall not project beyond the bands or rims ct ct. The roll A is also slotted longitudinally at c ct' to receive clamping-bars a2 a2, the ends of the printing-sheet A being passed under said clamping-bars, so that the sheet is securely held to the roll during printing, and yet is easily replaced by another sheet when necessary. A block a3 is secured to the roll between the slots a' a' to coperate with the cutter hereinafter referred to. The inking- 7o roll B is mounted in proximity to the printingroll A and may also be provided with bands or rims b, which form bet-Ween them a shallow recess in which is placed the inking-sheet B', the ends of the latter being secured by clamping-bars b in longitudinal slots b2. This roll may also be slightly cut away longitudinally,

as at b3,to avoid transferring ink to the clamping-bars of the printing-roll or to the ends of the printing-sheet. The bearings b4 of the 8e inking-roll are adjustable in order that the relation of the inking-roll to the printing-roll may be varied, if necessary, the bearings being carried by threaded studs b5, which pass through eyes be in brackets la7 and receive on 85 each side of said brackets adjusting-nuts hs. The brackets o7 support the usual ink-distributing rolls b9. The carrier C may also be provided with bearing rim or bands c, and may also be slotted at c' and provided with 9o clamping-bars c2 to secure a blanket to the roll, if necessary. A cutter-blade c8 is secured to the roll between-the clamping-bars and, in cooperation with the roll A, severs thev paper at each rotation. The bearings c4 maybe ad- 95 justably supported by threaded studs c5, with adj usting-nuts o6 on opposite sides of the guide-eyes c7 in the frame.

The feed-roll D is mounted in such proximity to the carrier-roll C that the paper is Ioo gripped between them and is fed forward at the same speed as the surface speed of the carrier C. A crank D or any other suitable means for imparting mot-ion to the feed-roll D may be secured to its shaft, and all of the rolls A, B, C, and D are geared together, so that they shall rotate at the same speed, gears A2, B2, C2, and D2, respectively, being secured to the several rolls or to their extended shafts, as represented in Fig. 2.

The paper to be printed upon is preferably delivered from a roll F, mounted in suitable bearings in the frame ofthe machine, an ordinary brake (represented at F') being applied to the shaft F2 of the roll to prevent the roll from overrunning.

The mode of operation of the machine will be readily understood from the foregoing description of its construction. paper from the roll F being carried between the feed-roll and the carrier-roll and between the carrier-roll and the printingroll and motion being imparted to the feed-roll, the several rolls rotate together, carry forward the paper, bring the paper into contact with the raised and inked characters of the printing-sheet on the roll A, and produce a cornplete impression of all of such characters at each rotation, ink the raised characters of the printing-sheet at each rotation, cut lthe paper after each impression from the continuous strip, and deliver the printed sheets into the receiving-tray G. Owing to the provision of the contact rims or bands no pressure is exerted upon the raised characters of the printing-sheet,witl1 the result that practically an unlimited number of copies can be printed from a single printing-sheet Without destroying its clearness. A single sheet of paper secured upon the inking-roll gives to the ink- The end of the ing-surface all the elasticity necessary to effect a thorough inking of the raised portions of the printing-sheet and might be dispensed with altogether without serious disadvantage.

It will be evident that the bearing or contact rims or bands may be wholly formed upon or applied to one of the rolls and that the arrangement of the several parts of the machine may be varied without affecting the general result, Wherefore the invention is not to be restricted to the precise construction and arrangement shown and described herein.

I claim as my invention- An apparatus for printing from embossed sheets, comprising a frame, a printing-roll having means for securing the ends of the printing-sheet in place, and provided therebetween with a cutter-block a3, an inkingroll, threaded studs mounted adjustably in the frame, and forming bearings for the inking-roll, a carrier-roll under the printing-roll having adjustable threaded studs forming its bearings, and provided with a cutting-blade to register with the block a3, and with a iattened portion opposed to the block @3,1mnular bearing-surfaces between the said three rolls to protect the printing-sheets from injury, and a feed-roll under the iukiug-roll, and coacting with the roll C to feed the web of paper through the machine; substantially as described.

This specification signed and witnessed this 31st day ot' October, A. D. 1898.

BERT MILLISON.

In presence of A. N. JESBERA, W. B. GREELEY.
