TO ALL WHOM -IT'MAY CONOERN:

Be it known that we, JOHN PoLnnMUs, of Jersey City, Stat'eof Newl Jersey, and CHRISTIAN H. LILIENTIIAL, of Yonkers, Westchester county, State of New York, have invented certain new and useful Improvements in Presses for Printing ou ContinuousSheets ot' Tin-Foil; and we do hereby declare that t-he'following is a full description of the same.

The object of our invention isto overcome the objection to handling tin-foil duringthe process of printing, and thereby leaving ink-stained finger-marks on it, and at the same time printing it with more rapidity than it is possible .to-do in single sheets on hand or power-presses; and the nature of our invention consists, rst, in

the combination of a continuons sheet of tin-foil with a revolving-cylinder press, whereby the inking, printing, and carrying forward of the sheet of tin-foil is continuous; secondin combining with a revolving-cylinder press for printing on a continuous sheet of tin-foil an intermittent shear-cutter, for the purpose of severing the tinfoil as it connes from oii` the cylinder into small sheets of 'printed matter; third, in combining, with the intermittent shear-cutter, a series of endless bands, for the purpose of Areceiving and carrying otf the subdivided sheets-ot' tin-foil. i

But to describe our invention more particularly, we will refer to the accompanying drawings, forming n. part of this specification, the same letters of reference, wherever they occur, referring to like parts.

Figure l is a plan view of the press.

Figure2 is a side elevation of the same. A

Figure 3 is a front end'lview ofthe press, showing the shear-cutter in red outline in theact lof cutting.

Letter A is the frame of the pressfhaving arranged init, on suitable bearings, two cylinders, B and 0oi` equal diameter. On the face of the cylinder Gis secured a series of printing-blocks or plates, D. These plates may be made of various sizes to print either large or small sheets of tin-foil, as may be desired for the ti`dicrent-sized packages. To ink them, a series of inkingand distributing-rollers, E, is rotated by means of cogwheels F on their ends, gearing intoa large cog-Wheel, Gr, 'on the end of the shaft of the cylinder C. The objectof this cog-wheel is also. to transmit a uniform rotatory motion through the cog-wheel B2 to the carrying cylinder B, the face of which, being arranged in close contactI with thevfaee of the cylinder C, so that as the sheet -oi' tin-foil H (shown by red outlines) from ofi' the reel I (arranged on the under side of the front end of Athe press) passes up between theA cylinders B and'G, and back over the cylinder B, it will receive an impression from the type-plate, and thus he printed without the intervention of any-extraneous pressure or of handling it. When printed, the continuous sheet of foil is carried forward and over the shell J, covering the upper front portion of the cylinder B. The front edge of the shell forms a straight edge. The object of this shell is, .irst,

f tovcarry the sheet of tin-foil away from the carrying cylinder; and, second, by means of its straight edge, form a bearing, against which a cutter may operate to' scvcr the continuous sheet into small Iprinted sheets. 'The cutting device, for severing the shectof tin-foil, ope-rates by means of areciproeating rod, K, attached to a crank, L, rotated by means of two bcvclled-pinion wheels, M, propelled by a wheel, N, -gearing into the cogwheel B2. Toregulate or control the action of the cutter in making or subdividing the continuous sheet into large or small sheets, the piniocn-whcel N is changed for either a. larger or smaller wheel, as may be required for the different sizes of printed sheets. '.lhe shear P is attached to a reciprocating rod, K, by an arm, R, and

has a slightly curved or rounded lower edge. The object oi' this curvature of edge, inconnection with the.

guide S for holding the reciprocating rod K in a horizontal position across the face ofthe press, is to cause the shear to act simultaneously throughout its entire cut. 'lo act' otherwise, that is, progressively, as shears ordi*V narily do, would be to cut the foil obliqucly, in consequence ofthe continuous'motion of the press in delivering the sheet. v

It will bc obvious that this precise arrangement for severing theA sheets of foil, as it comes from the press, v

may bc modified. We have used a- Vrotatory cutter with very goed results, and for soincpurposes find it te answer very well; but, as a rule, weprefer to use the reciprocating cutter, though we do not wish to be limited to the use ofit to the exclusion of any equivalent devices for the purposes set forth.

For the purpose of carrying othe printed sheets of foil W, after being severed from-the continuous sheet endless bands T are arranged to run over rollers which are propelled by cog-wheels V gearing into the cogwheel B2, and thus a relative and uniform speed is given to the endless bands to carry off the printed sheets fast enough to prevent the succeeding printed sheet from falling upon it to soil or dcfaee it.

It will `be obvious that the working of the press willbe effected by the application ot' any suitable power, by means of a crank or pulley and bands. As these are common and well known, it is not essential to describe them. A

Having now described our invention, we will proceed to set forth what wc claim, and desire to secure by Letters Patent of the United States, preinising, however, that our invention is based upon and limited to the single object of printing on a continuous sheet of tin-foil, and not ,intended to cover broadly the principle of operation exhibited in revolving-cylinder printing-presses; it being well knoxi'n that the substances of paper `and cloth d'er entirely from tin-foil, which requires great delicacy of treatment, not only in printing on it, but

also in handling it, and therefore ns a ncwmatciial, that is, n continuons sheet 'of' tin-foil, not at all in conflict with the general principles of printing-presses.

What we claim, therefore, is

1. In combination with a continuous sheet of tin-foil and shell J, the intermittent shear-cutter P, or equiva-l lent therefor, operatingas hercnbefore set forth, and for the purposes described.

2. We also claim, in a printing-press for printing on a continuous sheet of tin-foil, the combination of the intermittent shear-cutter with the series of rollers U and bands T, for the purposes'hereinbefore set forth.
