.CONSTRUCTION OF PRINTING-BLOCKS.

Be it knownv that I, BENJAMIN UNDER- woon, zof the city of Brooklyn, county oft` lKings, .State ,of New York, have invented a rnew ,and improved mode `of producing blocks, patterns, devices, or designs with which to tprint ornamental figures in ,colors upon oil-cloths, carpets, and other fabrics;

and -I ldo hereby .declare thatithe followingl is .a full ,and exactdescription thereof.

The nature lof my invention consists in providing aseres of suitable movable types of wood, Ametal .por other material, and so arranging lthem together that theyshall, col- -le.ctively, Yconstitute blocks, patterns, designs or devices, with which ornamental figuresk and designs may be printed "upon oil cloths,

carpets and other fabrics, in one .or ,more colors, just the same as Iif `the said blocksl` had been engraved or carved according toA the usual mode.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation, reference being had to the accompanying drawings, forming part of this specification.

Similar letters refer to like parts;

Figure l is a vertical view of one of my cases, lled with types composed into an ornamental design and constituting a block, ready for printing. The shaded squares represent the position of the elevated or impression types, on the surface of which the coloring matter is applied, when in the act of printing. Now, by stamping said types upon the fabric it is evident that an impression will be left thereon, corresponding to the device indicated by the ele` vated types. In the gure the space within the case not occupied by the elevated types is filled with low types or spaces. a, a, c, sides of case; a', end piece of case; b, furniture piece; c, screws forA loclng up; d, screws for` fastening on endvpiece a.

Fig. 2 is a vertical viewof a case for holding one kind of my movable types, the end piece a being removed. The case a, u, al, is represented as bein half full of types composed into one half of a design similar to that indicated in Fig. l. The bottom of this case is grooved, as seen at g, which grooves extend across the entire width of the bottom of the case. The types con# tained in this case all have angular projections on their lower partswhich fit and slide in these grooves. Fig. 3 is a section i of this case, showing the grooves g, and also the arrangement ofa line of theY types, with angular projections o on the bottoms. a, case; e, elevated yor impression types; f, low types or spaces; gtriangular grooves.

F ig; 5 `,is la sectional view vof a facsimile plate ofthe upper surface of the types shown in F ig. lcopied by the lelectrotype or cast in metal or other material.`

Figs. 6 and 7 are blank types or spaces lower parts. Figs.g8, 9, and l0 are elevated or impression types having similarV angular projections, l1..

`Fig-11, l's a furniture pieceused `in lockyhaving angular projections, h, o n theirl requires, or to engrave the required design o upon the block .by the usual mode of engraving, or to drive small pegs of wood or metal into the top of a suitable blockof wood, and produce the desired block orpati ory deviceY for printing oil cloths or other fabrics, I place the drawing of the required block before me just as a printer places his copy before him, and thenI set up thede vsign in one of my cases.;. Previous to commencing I unscrew the screws (l, (F ig. 1) and remove the end piecev a. When using the'angular bottomed types, (Figs. 6, 7,8, 9 and l0) IA employ the grooved casev (Figs. 2 and 3). Having observed on my copy the number and position of thev elevated types and blank types required .in the particular line which I am composing, I select thecorresponding types, one vby one, andplace them so that their angular bottom projections' 7i, .shall` enter the groove g, kin which said projections are made to fit; slidel the type down the groove toits `iappro-4 priate place.` Inthis manner I lill out a line evenly tothe sides ofthe case v(a) and, repeating the operation according to copy,

Then I` fill up the Whole case with types. Some of the elevated types contain one impression surface, and some more than one, as in Figs. 8, 9, 10, where 7c shows the impression surfaces and Z open spaces. lVhen the case is full of types, composed in a design', I finish by putting in, against the types, a metallic furniture piece (b, Fig. l1). This also has an angular projection 71,' on the bottom. I now screw on the end piece a firmly, by means of screws which fasten in the other parts of case a. This done I turn the screws c, which revolve through nuts contained in the end piece a. `As I turn these screws (c, Fig. l) they press against the furniture piece (E) andpush it up against the types. In this manner the whole form is locked up securely, rendering it impossible .for any of` the types to drop out. I would here remark that the angular projections fitting in` grooves g, are intended to afford further security against the possibility of the types dropping out when the block is turned in an inverted position. Whenv my case is filled with types and locked up, as described, it constitutes a block and is ready for printing, or for duplication by the electrotype, or casting or molding in any suitable material. From any such facsimile plate I can print justas well as 'from the original types.

A. section of such a facsimile late is seen at Fig. 5. IV hen required for cylindrical Aprinting I bend these plates around suitable cylinders, and thus the blocks, patterns designs or devices, which I first set up with movable types, may be appliedv to print any kind of suitable fabrics much in the same manner that calicoprinting is accomplished.

Having thus described my invention I printing oil cloth, carpetsor other fabrics,

by the combination and arrangement of sections or type such as herein particularly described, by which an endless varietyofpatterns may be produced from the samesections variously disposed, at a'comparatively small cost.
