WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of November, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Jean Cirille Marius Beziat, Her special licence that I, tho said
Jean Cirille Marius Beziat, my executors, administrators, and assigns, or
such others as I, the said. Jean. Cirille Marius Boziat, my executors,
administrators, and assigns, should at any time agree..with, and no others,
from time to time and at all times thereafter. during the term therein
expressed, should and lawfully might make, use, exercise, and vend, within
the United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN THE MEANS OR APPARATUS
EMPLOYED FOR PERMITTING, STOPPING AND REGULATING THE PASSAGE OF STEAM,
WATER, AND GASES," upon the condition (amongst others) that I, the said
Jean Cirille Marius Beziat, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention, and
in what manner the same was to be performed, and cause the same to
be filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE; that I, the said Jean Cirille Marius Beziat, do hereby
declare the nature of the said Invention; and in what manner the same is
to be performed; to be particularly described 'and ascertained in and by the
following statement thereof, reference being bad to the accompanying
Drawings, and to the letters and figures marked thereon, that is to say :-
.
The object of this' Invention is improved means of permitting, stopping,
and regulating the passage of steam, water, and gases. For this purpose
I

page_text: employ a valve opened and closed by a "helix" (hélice) or sort of screw
action, that is to say, I form in the valve stem or spindle a helical or spiral
groove, path, slot, or channel, or path or channel of the curve or shape of a
screw thread, in which works a pin or projecting piece on a rod, so that by
turning the rod or the spindle the opening or closing of the valve is effected to
the desired extent, and the passage of the steam, gas, or water permitted,
interrupted, or regulated.
I now proceed more particularly to describe, with reference to the accom-
panying Drawings, in what manner my Invention may be carried into effect.
The Drawings show two applications of the apparatus. Figure 1 is a
vertical section of the apparatus arranged for employment in combination
with a governor to regulate the supply of steam to an engine in substitution
for the throttle valve arrangement commonly used for the purpose; Figure 2
is a front elevation of the valve box; Figure 3, plan of the valve and gear.
A is a conical valve; B, its seat fixed into a valve box H; D is a hollow or
tubular spindle connected by its stem or sbank d with an arm M attached to
and operated by a governor, not shewn in the Drawing. The stem d passes
through the stuffing box G and gland g. a is a rod forming part of or fixed
to the valve A, and fitting concentrically or telescopically within the spindle D
in such manner that it may be free to slide smoothly in the spindle in either
direction when actuated as herein-after described. I is a double spiral or
helical channel, path, or slot cut in the spindle D; i is a pin passing through
and fixed to the rod a in such position as to be capable of working in the path I,
both ends of the pin projecting from the surface of the rod a; C is a cotter
passing through and fixed to the rod d, and bearing against the gland g, while the
shoulder of the part D abuts against the stuffing box G in such manner that
though the spindle D, d, is free to turn on its own axis, it is nevertheless prevented
from moving to and fro longitudinally; E is a collar attached by a cotter m
to a rod a' projecting from the valve face; this collar E is formed with slotted
lugs e, e, through which pass pins f, f, which are fixed to the valve box II and
prevent the valve from turning, but leave it free to move forward and backward,
that is, to and fro in the longitudinal direction of its axis, when actuated as
herein-after explained. When by the action of the governor the arm M.
imparts motion in a rotary direction to the spindle D, the sides of the spiral
slot I bear against the pin i as the spindle turns, whereby the pin is forced to
move along the slot and the rod a consequently caused to slide forward or
backward moving the valve A with it according to the direction in which and
the extent to which the spindle D, d, is turned by the arm M, and hence the

page_text: valve is opened or closed, as the case may be, to the required extent; L is the
steam-way through which the steam is admitted, and h, the passage into which
it passes when the valve A is opened; P is an ordinary lubricator for lubrica-
ting the spindle, but is not used when the latter is vertical.
Figure 4 is a vertical section, and Figure 5, plan of a modification of the
apparatus arranged as a steam or fluid inlet or outlet tap; A is the valve; B,
its seat, and H the valve box; D, hollow or tubular stem on the valve A, form-
ing a sort of socket, and having a double spiral slot or channel I cut or formed
in it, as shewn. This tube D fits telescopically over the part q", of a rod q,
9,9", being free to slide smoothly upon the rod in either direction when
operated as herein-after described; the rod 9, 9', q, has at one end a handle M
for turning it, and near the other end a pin i fastened into and through it,
and so placed that it may work in the slot I, when operated as herein-after
explained. The rod passes through a stuffing box G, and gland 9, and is cone-
shaped and enlarged at the part q', to keep it steam tight, and a cotter C is
fixed into it at 9, so that though the rod is left free to turn, it is prevented
from moving longitudinally. The valve A, and the socket D, are prevented
from turning by the pins f, f, passing through the slotted lugs e, e, on the
collar E, the parts E, m, a', e, and f, being arranged and operated as described
in reference to parts marked with like letters in Figures 1, 2, and 3.
extent.
When the handle M, is turned in the desired direction and to the required
extent, the rod 9, 9', 2", will be turned correspondingly, and its pin i bearing
against the sides of the slot I will force the stem D to slide backward or forward,
as the case may be, and will hence opon or close the valvo A to the desired
When the valve is opon the steam, water, or gas passes from L to h;
P is a lubricator as before. Although I have shewn in the accompanying Draw-
ings the valve A, as conical, a flat or flat-faced valve may be used if preferred.
Having now described the nature of my said Invention, and in what manner
the same may be performed, I declare that I claim,-
First, the combination of a tubular or hollow piece fitting round a rod, and
having helical or spiral slots or channels formed in it, with a conical or flat
valve for the purpose of causing such valve to slide or move, that is to say, to
open and close all in the manner herein-before described.
Second, the combination of my herein described improved valve arrange
ments with Watt's governor, or other governor or regulating apparatus, for
regulating or controlling the admission of steam into steam engine cylinders,
whereby the action of such engines is regulated in the manner herein-before
described.

page_text: Third, the employment or application of the said valve arrangement as a
tap for the admission and discharge of water, steam, or gas, in the manner
herein-before described.
In witness whereof I, the said Jean Cirille Marius Beziat have here-
unto set my hand and seal, this Thirteenth day of May, in the year
of our Lord One thousand eight hundred and sixty-one.
Witness,
BRESSON.
