lTo ALL WHOM 1T MAY -coNeEnNz OTTO -HEINIGKE AND MORITZ LAEMMEL, 'OF BAY RIDGE, NEW- YORK.

Lettera Patent No. 28,481, dated May 29, 1860', reissue No. 2,633, dated June 4, 1.867.

Be it known that we,`O'rTO Hunvrexn and MORITZ LAEMMEL, both of-.Bay Ridge, in the county of Kings, and State of New York, have inventeda, new and improved Method of Producing Mosaic Veneers; and we do herebydeclare that the following is a. full, clearfand. exact description thereof, reference being had to the accompanying drawings, making part 'of this specification, in which- Figure lis a. perspective view of a part of the-apparatuswhich we have successfully used in working our said invention. 'I d d l I Figure 2, a like view of :mother partof the apparatus which we have used for the-purpose.; and

Fighre 3. is n perspective view of a block prepared accordingto oursaid invention, and readyforbeing'cut into lveneers. I l l d The same letters indicate like parts Vin all the figures.

` Our seidA invention relates to the -production ofmosaic veneers or surfaces, and consists, iirst, in the process of forming prismetoidal. rods of a. 'suitable form,n.nd for-the various colors required to form, when put together sidevbyside, surface with the required desigrn'by forcing through apertures of the form of the crosssectiorr'of the-intended rods, a plastic materialgri'vhiehafterthe rods havebeenffor'ined-will become, or which 'may be rendered, of snflicient hardness-t0 he'u'sedzals'fiveneer; lrind,'second,'iuv uniting -such Astrips so formed intohloclrs, the cross-section of which'will be of the. form of the surface tovbe veneered orof a section thereof. In working our said process wetake somesuitableinalieridh which must be sufliciently plastic `und tens.- cious at first to'ndmit of being forced through `un aperture' f the sizeandform of the cross-section of the rod vintended to'be produced, and which afterwards"will-become.or may be rendered sufficiently hard'to answerfor l veneer'ing'surfnces, The material which we' have successfully used, and which we' preferfor` this purpose, is' composed' of pipe-clay ground with linseedoil to a. putty-lilseconsistency.` We have used it successfully when gronndor mixed to different consistencies, but prefer'to'use 4it* of the consistency of freshly inade putty. The material thus prepared we divide into a number of parts equal to :the number olf colors contained in the pattern which -is to be imitated. Each coloris new forced through n metal plate containing one or more small :tI-pertures,- whereby the plastic mass is divided into long, .thin strips. The apertures in the metal plate'give to the strips-.the required form, and byusing an apparatus such as is shown in iig. l, a number of these strips,.a.nd

. -of different colors, may be formed at the' same trne. This apparatus contains a. block, A, with a, large number 'of cylindrical opcnings,.a, (see fig.- 2,) to rcceive'the plunger b, and a. perforated metal plate, B, is firmly secured to the under side of the hloclcA; The perforations in the plete B'correspond in she-pe to 'the shapeA of 1;h e several colorsin the-'pattern to he copied, and each of the openings a is vlled with :1 quantity of the plastic material of the desired color, For filling theopening a we use a device such as represented in fig. 2, consistirg: of c cylindrical vessel, C, with a pointedxnouth-piece,. c, at the bottom. A piston,..D, is moved up unddown' in lthe' interior of the vessel C .by means of a. lever, E. The mouth-piece c is brought successively over theopenings contained in the block A, and by'depressingthepiston D the material contained in the'cylindriculv'essel A(lis forced out into the openings 'ai Several vessels, (Ihre kept on hand, and euch one is i'illed with. dilferent color, Aso that the openin-gs in the block A can be filled with the proper colors in an easy rn'anner. Affter allfthe openings ahavebeen llcd the block A is brought 'under the plunger-s b, fig. 1, end

by depressing these 'plungers the messfcontnincd in said Openings is forced opt through the perforations in the plete B, forlning-small strips of different colors, thc colors being previously arranged according to the patternl to' bcfcopied. ,An'inclin'erl board', F., receives`- the strips as they ooze outfof the h-oles in the plate B,

unid-when long' enough they arefspardted from the platend'pushed togetherl-by'means of n. straight-edge,

'an'd they are now united by pressing-them together or by some suitable cement. By these means one portionlafter 'another- L of the pattern is` repres ented by small, thin layers, each layer being formed by a number of -said strip-s'.v By uniting these layers, blocks G are forlned, the cross-section ofwhich represents the pattern to he represented, o r e portinnofthe same, as clearly shown in g. l3. These blocks are new cut up crosswise into a number of thin plates, each plate of the thickness. of au ordinary veneer; and by fastening the plates on ssuitable snrfacefin the desi-red ordenthe pattern to be represented is faithfully copied.

l From the foregoing it ivill be seen that mosaic veneers can be produced with any desired design'antl' any variety of colors, and multiplied to any extent at much less cost than by any other process.

We have above stated the material which we have used with success, but we wish to be,A understood that We do not claim totliave invented the composition ofthis Ivnaterial; as it has long been known and use-fl for vother purposes; nor do we wish vto bennrlerstootl as limiting our claim of'inventiorn to the process of makin-g mosaic veneers from the material described, as any other material maymbe substituted which possesses the specifiedproperties of plasticity that it may he formed into strips byheing forced through apertures of the reqiiireil` form, andwhiehwill become, or which can be rendered, sufficiently bard -to veneer surfaces.

What we claim as new, and desire tolsecure by Letters Patent, is- I 1. Thewithin-described methodk of producing mosaic veneers from Stripsf'ofany desired cross-section, and

of various colors, said strips being formed by *pressing a suitable plastic Amaterial, which will harden' after having. gone'through the whole process, throughr openings of the-required shane. substantially as and for the purpose described. y

2. Uniting the strips formed asabove (lescliloeriv into blocks a cross-section of which represents the pattern to berepresented by the mosaic vencer, or a portion of the same, substantially in the manner and for the purpose specified. i l
