Letters Patent No. 70,421, dated November 5, 1867.

Be it known that we, JOHN TaDAVIS, of Jersey Gityyin the State of New Jersey, nndWILLInM 0:. SELDEN, of Brooklyn, in the State of New York, have invented. a new. and useful Composition for Making Joints and Packing; and we do hereby declare that the following is a full, clear, and exact description of the same, and
arls' soaasto'ne. one art and sul hate of zinc one -)art. P 7 1 1 1 J- "combustible.
of the methods of compounding and using it.
The invention consists of a composition of paper-pulp, soapstone, and sulphate of zinc, manufactured in proper shape for packing striding-boxes, making joints, and like uses.
The above substances are usually compounded, by weight, in the following proportions: paper-pulp, sixteen The pulp givos the composition most of its body andconsistency; thcsoopstone acts as a lubricant; and the sulphate of zinc makes it to a great extent non- The composition is made as follows: Powdered soapstone and a solution of sulphate of zinc are added to the paper-pulp when in a semi-fluicl state, the mass. i
For making joints, the-composition is spread out in sheets of the desiredthickness, making paper, or several sheets may be pressed together. When used for packing, the soft composition is ei'therpoured or pressed into moulds of the desired shape, or forced out through a die, the form of which determines the section. Packing-is made, also, by rolling up sheets ofthe composition till the desired size is attained. After the composition is put into shape, it is simply dried, when it is ready for use. The packing for stuffing-boxes is generally made circular, in section, so that it may have an opportunity to swell when it absorbs moisture. The packing is often encased in cotton cloth, and, by proper machinery, a case may be knit about it. The use of the casing is principally to prevent. injury to the material before it is put in place, and
in making sheets for joints. The sulphate of zinc may be replaced i to confine the soapstone powder which adheres to the pulp.
It is not neccssaryto use the exact proportions above mentioned. The soapstone may be entirely omitted 11 the composition by many other non combustible mineral substances which dissolve in water, or which, not being gritty, will adhere to the pulp like the soapstone. .The sheets of the composition, wheuused for joints, may have cloth cemented to them.
The composition may be madeinany of' the various forms which are given to India rubber, for the purpose of preventing leakage, and may be applied to the same uses in substantially the same manner.
We claim as new, and desire to secure by Letters Patent- 1. A composition of paper-pulp, soapstone, and sulphate of zinc, for the purposes specified.
.2. A composition of paper-pulp and sulphate of zinc,
or i'tszcquivalent, substantially as and substantially as and for the purposes set forth.
