i time the strength of metallic materials. \Ve

To all whom i/; may concern:

Be it known that we, JULiUs A. Inxsn and GEORGE J. BABSON, citizens of the United States, residing, respectively, at \Vest Medford and Boston, in the counties of Middlesex and Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Fabrics, of which the following is a specification, reference being had to the accompanying drawings.

The object of this invention is to provide a fabric or material for various purposes, especially for the purpose of making articles which require in their use or which can advantageousl y possess the characteristics of pa per, and at the same time possess the quality of strength in a degree far in excess of that of paper.

it is well lUIOWU that paper has been ap plied to many uses in the mechanic arts by reason of its peculiar texture, pliability, submission to manipulation, and cheapness, and that by the application thereto of waterproofing and fireprooting compounds it is rendered capable of use in exposed positions, and that by excessive pressure it is rendered capable of resisting great wear; but with all these advantages in use it lacks strength to such a degree as will permit of its use under certain conditions requiring a capability of resisting strain in various directions.

Heretofore finished paperin sheets has been applied and secured to sheet metal upon one or both sides thereof in order to secure the advantages which constitute a part of the object of our invention; but in such cases the material resulting from such a combination of the substances mentioned has usually been limited in area and outline to that of the article made from such compound material, and in a degree necessarily so by reason of thelimited area of the sheet metal to be obtained for association with the paper. Furthermore, in such cases finished paper alone has been combined with strengthening materials, and a l Ways with an intervening cement or adhesive agent.

By ourinvention we are enabled to produce a fabric or material, either in continuous webs orlengths of desired widths, which possesses all the characteristics of paper, and at the same accomplish this rcsult the prod notion of such a material-by using as the base or foundation thereof wirocloth of a desired mesh. tineness, or c arseness in the strands thereof, and as the outer portions of said material we employ paper-pulp. We combine with a con tinuous web of wire cloth continuous webs of pulp in such manner that the pulp is forced through the mes-hes of the wirc-clotli,and conr pletely envelops and covers the same, so that in outward appearance the material is exactly like that of paperof tile same texture and quality, whilcit is at the same time capable of being rolled into rolls for shipment and transportation, to be unrolled for use in continuous sheets or in parts thereof, which may be out in any desired shape for the manufacture of desired articles, especially those which can be struck up or formed without seam, while those requiring seams may be provided with the same at desired points, and the parts secured together by paste or cement, as in ordinary paper articles. The cementation of joints in our material is assured by reason of the fact that all points on its outer surfaces are of pulp. Again, such material is capable of being ornamented by the application thereto of finished paper or other material, or by the finishing the surface of the pulp itself, varnishing, painting, or treating with any suitable finishing, waterproofing, or fireproofing compound, or in the latter case of combining with the pulp itself of asbcstus in the usual well-known proportions.

Our invention therefore consists in a fabric or material, in continuous sheet or in roll form, which consists of wirecloth embedded or completely covered with paper-pulp.

Referring to the drawings, Figure 1 repre sents a roll of fabric or material or compound paper made in accordance with our invention, and Fig. 2 is a transverse vertical section of the same.

Like letters refer to like parts in both figures.

A represents any suitable pulp, and B rep resents the wire-cloth embedded therein.

For the purpose of disclosing one method or manner of making our material, which method and manner is not claimed herein, as it will back of (in the line oi feed) said pressure- 'oliers we provide means for su iiporting the continuous sheet or veb or wire-cloth in roll form, and conduct by hand or suitable devices the leading end of said cloth into, between, am through the said pressure-rollers, 1 nd between the two continuous sheets or webs oi pul passing thereinbetween, so th-it by the pr ure'rollers we compress continuous sheet of pulp against the opposite surfaces and into and through the meshes ot' the wirech th, which may or may not, as desired, he iirstwaterprooted to prevent rusting. Ai'te l through said rolls, the fabric dclive ed to any suitable ilrying mechanism, and subsequently from the machine as wirecloth (30mpletely covered and ember ded with pulp.

lr'e iind this fabric or material. sul'iieiently flexible for all purposes to which any other material of this nature is adapted. and we also find it susceptible of division into sections of desired area and contour ibrspecia purposes.

\Ve deem it proper to st ate that our ii yention consists in the fabric or material herein described irrespective oi'any method oiinainilecturing the same, because still other meth ods may be devised than that specified, such as interposing inde pendentsquares or pieces other than continuous sheets of wire-cloth be tween the sheets of pulp.

"We aware that heretofore a wire form of an article has been made and the sa ne com- .iletely covered with pulp, to produce the aricle in accordance with the shape or form .1111 e of wire, and we no not theretorebroadly in covering wire with pulp; but hut we claim, and desire to secure by Let ters liateut, is

1 its an article oi'manui'aeture, a compound material consisting oi'wire-eloth completely e .ieuded and cover d with pulp, substantially as spcciiie 2. A continuous sheet, roll, or web of material consisting of wire-cloth embedded and completely covered with papeupulp, substantially as specified.

' 1e method of making the compound or material herein specified, which conis in uniting by compression continuous lets or webs oipulp and oi wire-cloth in such l nor as to completely cove and embed the latter in and bi the former substamiallv as lpceiiicl an article of manufacture, the fabric or terial herein described, consisting of wireeloih rendered wa er-repellcnt and covered and having its meshes iilled with pulp,

substantially as specified.

l testimony whereof ue have ailixed our surnatnres in presence oi two witnesses.
