page_text: LETTERS PATENT to Jonathan Fathers, of Wales, in the County of York,
Engine Driver, for the Invention of "IMPROVEMENTS IN WATER, STEAM, AIR,
AND OTHER SIMILAR VALVES OR COCKS, THE SAID IMPROVEMENTS HAVING
REFERENCE TO THE SPINDLES, COVERS, AND PACKING THEREOF."
Sealed the 8th February 1878, in pursuance of an Order of the Lord Chancellor
and dated the 1st August 1877.
PROVISIONAL SPECIFICATION left by the said Jonathan Fathers at the
Office of the Commissioners of Patents on the 1st August 1877.
JONATHAN FATHERS, of Wales, in the County of York, Engine Driver. "IMPROVE-
MENTS IN WATER, STEAM, AIR, AND OTHER SIMILAR VALVES OR COCKS, THE SAID
IMPROVEMENTS HAVING REFERENCE TO THE SPINDLES, COVERS, AND PACKING
THEREOF."
These improvements relate to water, steam, air, and other similar valves or cocks,
and consist in the employment of a spindle made with a suitably shaped swell or
collar, which when the said spindle is drawn up to its full height, will enter and fit
tight into a similar shaped recess in the valve cover, or into a recess in the valve
case below the said valve cover, for the purpose of preventing the escape or passage
of the water, steam, air, or other combination of elements, or elements from the said
valve or cock along or by the spindle.
The swell on the valve spindle can be covered with leather or other suitable
material, or the recess can be lined with leather or other suitable material.
The spindles and covers of the improved valves or cocks can be made of the same
materials as ordinarily in use.

page_text: The valves or cocks constructed according to this Invention will require only a
minimum quantity of "packing," and in some cases the "packing" can be dis-
pensed with.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Jonathan Fathers in the Great Seal Patent Office on the 9th
February 1878.
JONATHAN FATHERS, of Wales, in the County of York, Engine Driver. "IMPROVE-
MENTS IN WATER, STEAM, AIR, AND OTHER SIMILAR VALVES OR COCKS, THE SAID
IMPROVEMENTS HAVING REFERENCE TO THE SPINDLES, COVERS, AND PACKING
THEREOF."
"
The object of this Invention is to take off the pressure from the gland packing
of the spindles of valves or cocks, and in some cases to obviate the necessity of using
packing."
This Invention consists in the employment of a "spindle,” with a suitably shaped
swell, collar, or projection, and in the employment of a "cover" with a recess similar
in shape to the swell, collar, or projection, into which said recess the said swell, collar,
or projection (formed on the spindle) will enter and fit tightly when the said spindle
is drawn up, so that if steam is admitted into the valve or cock, and the spindle
(with the projection) is drawn up and fits tightly into the recess in the cover, there
can be no pressure of steam on the "packing" in the gland chamber.
In adapting my Invention to valves or cocks already made, according to the old
plan, with straight spindles, I make a loose bush with a hole and recess of suitable
shape to receive my improved spindle; this loose bush has a screwed projection or
boss; I bore a hole in the cover to receive my improved spindle, and having chased
it I screw therein the loose bush, which will receive and act with my improved
spindle.
The accompanying Drawings show my Invention as applied to a through-way
steam stop valve.
Figure 1 shows a longitudinal vertical section of a valve; the spindle and valve
thereon being drawn up, and the valve being open, the steam will fill the casing
and press on the under side of the conical projection, and cannot escape into the
gland chamber and act on the "packing" therein.
Figure 2 shows my improved spindle (and a valve) in elevation, the valve and
spindle being down; and it also shows a bush in section, such as I fit to old valve
covers, in order to adapt my improvements thereto.
Figure 3 shows my improved spindle (and a valve) with a bush of the same
description, and for the same purpose as that shown in Figure 1, the spindle and
valve being shown down.
Figure 4 shows a horizontal section of the spindle and bush through the line A, A,
(Figure 2).
Figure 5 shows a plan of the spindle and bush.
My Invention can be applied to all valves and cocks in which the spindles
actuating the valves have a reciprocating motion, and the swell, collar, or projection
on the spindle, and the similarly shaped recess in which the projection enters and
fits can be of a conical or curved form, or any suitable modification of these
forms.

page_text: Having now described and particularly ascertained the nature and object of my
said Invention, together with the manner in which the same is to be or may be
performed or carried into practical effect, I would reinark in conclusion that I claim
as the Invention secured to me by the herein in part recited Letters Patent, the
improvements in the spindles, covers, and packing of valves and cocks, as herein
specified and described, and illustrated in the accompanying Sheet of Drawings.
In witness whereof, I, the said Jonathan Fathers, have hereunto set my hand
and seal, this Second day of February, in the year of our Lord One thousand
eight hundred and seventy-eight.
