PROVISIONAL SPECIFICATION.
An Improved Form of Packing for Steam Engines or the like.
We GEORGE BEEFORTH NEWTON, and WILLIAM HOLIDAY, trading as
Newton Bros., Prince's Dock Side, Hull, in the County of York, Manufacturers, do
hereby declare the nature of this invention, to be as follows:-
The object of our invention is to make an improved form of packing for steam
engines and the like, which shall be simple of construction, but shall at the same
time perfectly bed or conform itself to the parts of the engine to which it is
applied, thus being very effective and entirely preventing any escape of steam.
We construct our invention as follows:-
We employ suitable pieces of asbestos, silicate of cotton or any other suitable
material, which is rolled or wrapped up into triangular shaped pieces, one of the
pieces being preferably V shaped, thus having two equal sides, the other pieces
being both alike, both having all their sides unequal, the whole three pieces when
placed together forming a perfect square. Over the apex of the V shaped piece
we place a layer or covering of any suitable metal, this covering is continued and
covers entirely the two sides of the said V shaped piece, so that when the three
triangular pieces are placed together, the hypotenuse or longest side of the two
unequal pieces bear against the two metal covered sides of the said V shaped piece
and prevent friction between the three parts, the base of the said V piece forming
the inner side of the square when the pieces are placed together, the whole square
wrapped with a suitable covering of asbestos or the like.
The packing is placed in the stuffing box with the base of the V shaped piece
bearing against the piston rod, against which it is forced by compressing together
the other two unequal sided pieces thus making a perfectly tight packing and
entirely preventing any escape of steam, with a minimum amount of friction.

We, GEORGE BEEFORTH NEWTON and WILLIAM HOLIDAY, trading as
Newton Brothers, Prince's Dock Side, Hull in the County of York, Manufacturers,
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement :-
The object of our invention is to make an improved form of packing for steam

page_text: DESCRIPTION OF DRAWINGS.
Fig. 1 shows section of our improved packing.
Fig. 2. shows section of stuffing box with our improved packing applied.
We construct our invention as follows:-We employ suitable pieces of asbestos,
silicate of cotton or any other suitable material which is rolled or wrapped up into
triangular pieces, one of the pieces A, being preferably V shaped, thus having two
equal sides, the other two pieces B, B, being both alike, both having all their sides
unequal, the whole three pieces when placed together forming a perfect square.
Over the apex C of the V shaped piece, we place a layer or covering D of any
suitable metal, this covering is continued and covers entirely the two sides of the
said V shaped piece, so that when the three triangular pieces A, and B, B, are
placed together the hypotenuse or longest side of the two unequal pieces, bears
against the metal covered sides of the said V shaped piece A, and prevents or
lessens the friction between the three parts, the base of the said V piece forming
the inner side of the square wben the pieces are placed together, the square being
wrapped with a suitable covering E of asbestos or the like.
The packing is placed in the stuffing box with the base of the V shaped piece
bearing against the piston rod F, against which it is forced by compressing together
the other two unequal sided pieces, thus making. a perfectly tight packing and
entirely preventing any escape of steam with a minimum amount of friction.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
Packing (for stuffing boxes of pistons, cylinders and the like) constructed of
angular pieces A, B, B, faced with metal in the manner or substantially as shown
and described.
