Letters Patent No. 110,833, dated January 10, 1871.

IMPROVEMENT IN THE MANUFACTURE OF ARTECLES FROM PAPER PULP.

The Schedule referred to in these Letters Patent and making part of the sump.

To all to whom these presents shall come:

Be it known that I, Fnaxors OURTIs, of Foxhorough, in the county of Norfolk and State ofMassachnscttsdiavc made an invention of a new and useful to which our invention is applicable, the material be- 'ing animal or vegetable fiber, or both combined.

The process oy which the frames are made is in part as follows:

The fihcr, which may he cotton, linen, jute, manilla, hemp, flax, wood, wool, leather, or other animal or vegetable libcr, is subjected to a picking or cleaning process, aml thcn reduced in a cutter or picker, or other suitable machine, and boiled in alkali from six to flirty-eight hours, until it-is sufiicicntlysoftencd for the purpose.

The libcr may also be used in the natural state without boiling. 1

The stock fiber is now to he reduced to thepropcr consistency, by being out, broken, or separated, so

that the fibers will lie together, and the-whole mass bc formcd into a pulpy condition, so that .it may be formed into a thick felt and shaped into. the mold or 5 niturc, carvings, moldings, car trimmings,

die, or it may be deposited onto thc mold or die in a pulpy state, mixed with water The fiber may be reduced in an ordinary paper onginc, or by any othcr process suitable; or it lhay be also formed into the body or felt upon a'papcr machiuc, and used in the form of a thick paper felt; or it may be formed upon a wire gauze or other perforated surface, from which the water has been pressed or drawn through the fibers by means of suction produccd by hydraulic, atmospheric, or steam pressure.

Having thus reduced the fiber to the proper conditron, I now proceed to make the frame orother device.

I prepare a die from or in imitation of the article I wish to produce, either by elcctrotyping or otherwise. I now take the fiber, either in the felted form or in the pulpystatc, as I may prefer, and form or mold it into the mold or die, and by manipulation and pressure I. force the fiber into the mold'until it reccivcs the perfect impression and is a perfect fac simile. This is now to. be dried, and, if necessary, .when dry, to be subjected to heavy pressure until it is in perfect form and very smooth, and capable of receiving a very smooth surface.

The frame is now to 'lzc water-proofed, which may be done with shellac or varnish, or by any of theproccsscs by which paper is water-proofed, and is then ready to be painted, gilded, flocked, or ornamented in any'dcsired manner; I

The advantages which ornaments of this class posscss are V First, cheapness, as I believe. they can be produced more cheaply than by any other process, as one the or mold will produce an unlimited number at the. rate of tln'cc to six per minute.

Second, the ornaments are much lighter, and will not crack nor shrink byexposure to changes of the atmosphere, and are very tough and durable.

Third, they are capable of being produced in an infinitc variety, and of the most beautiful pat-terns and dcsigns, for excelling plaster, wood, or any of the materials now in use, which are all more or less effected by the atmosphere and moisture and are easily broken.

There are many purposes to which my invention can be applied, such as brackets, ornaments for furcrpots, cuspadors, table-mats, trays, book-covers, 85c.

Claim.

I claimlhc heroin-described manufacture of articles of ornamcnt.
