"
of A. NEW AND USEFUL COMPOSITION TO BE USED IN SHAFT JOURNAL BOXES."
-A communication by John Absterdam, residing at New York, in the
County and State aforesaid.
Sealed the 19th September 1862, and dated the 8th July 1862.
COMPLETE SPECIFICATION filed by the said Orange Watson Child at the
Office of the Commissioners of Patents, with his Petition and Declaration,
on the 8th July 1862, pursuant to the 9th Section of the Patent Law
Amendment. Act, 1852..
TO ALL TO WHOM THESE PRESENTS SHALL COME, BE IT
KNOWN, that I, ORANGE WATSON CHILD, of the City, County, and State of
New York, cf the United States of America, amin possession of an Invention
of A NEW AND USEFUL COMPOSITION TO BE USED IN SHAFT JOURNAL BOXES," com-
municated to me byJohn Absterdam, now residing at New York, in the County
and State aforesaid,and I do hereby declare that the nature of thesaid Invention,
and the mannerin which the same is to beperformed, to be particularlydescribed
and ascertained in and by the following statement thereof, that is to say :-
The nature of the Invention consists in a mineral composition composed
either of sulphur and plumbago, or the same and steatite metallic oxides or
sulphurets,orvarious other substances, the whole being capable of being fused
or reduced to a liquid state, and being run or cast into a box or bearing so as
Paine d

page_text: to be used under the journal of a shaft in a similar manner to which what is
termed "Babbitt metal" is generally employed.
In carrying out the Invention I take a desired quantity of sulphur, which I
place in a suitable vessel, and applyheat to the outer surface of the said vessel
so as to melt or liquify the sulphur, after which I add to the latter a quantity
of ground or pulverized plumbago. There may be added to the sulphur and
plumbago, a small quantity of powdered steatite, or metallic oxide, and a few
drops of any vegetable or animal oil. The proportions of the ingredients thus
used may be ten parts by weight of sulphur, and five parts by weight of
plumbago, or ten parts of sulphur,.three parts of plumbago, one part of
steatite, and one part of any metallic oxide. The whole should be well
stirred together, and the heat gradually increased until the ingredients are
completelyincorporated together, and the mixture mayassume the consistency
of a thick paste capable of being spread into a journal box, or of being pressed
into a mould, as circumstances. may require. If not intended to be used
immediately for such purposes, the mixture or composition maybe cast in the
form of ingots, which when subsequently required for use may be remelted or
softened by heat. For the purpose of indurating or hardening the com-
position of sulphur and plumbago, I add to it while in a state of fusion, other
substances, such as-metallic filings, or oxides, or earthly matters; and. I
employ the oil because I have found its effect on the sulphur to be a useful
one. This composition may be applied to advantage in the manufacture of
patterns for light castings, or it may be utilized in various other ways, it being
particularly advantageous in its application to shaft journal boxes as a
substitute for the metallic fillings usually employed therein. It operates to
cause the shaft to run with little friction and to require but little.lubricating
oil or material, the action of the sulphur being to. prevent.the journal from
becoming heated.
What I claim as the Invention is the composition of sulphur and plumbago
alone, or the same and some other material or materials substantially as
herein-before described.
In witness whereof, I have hereunto set my hand and seal, this 17th
