PROVISIONAL SPECIFICATION.
A Straightway Valve or Cock.
I, HENRY BRECKNELL, of Lawrence Hill, Bristol, in the County of Gloucester,
Engineer do hereby declare the nature of this invention to be as follows
The object of my Invention is to produce a valve or cock in which the movement
of the plug is vertical, instead of a rotary movement, according to such appliances as
hitherto constructed.
In carrying my invention into effect, I employ a truly cylindrical plug, and
arrange the same so as to slide freely within the barrel, and close or open the ports
or "ways" formed therein, I may employ adjustable metal faces, or a suitable packing
of asbestos «
ог woodite," for the purpose of keeping said plug fluid or gas tight
within the barrel, or body of the cock, and may employ any suitable mechanism or
device for raising and lowering said plug, when opening or shutting the valve or
cock.

COMPLETE SPECIFICATION.
A Straightway Valve or Cock.
I, HENRY BRECKNELL, of Lawrence Hill, Bristol, in the County of Gloucester,
Engineer, 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 my invention is to produce a valve or cock in which the movement
of the plug is vertical, instead of a rotary movement according to such appliances as
hitherto used and constructed.
In order that my invention may be the better understood I have appended the
accompanying sheet of drawings, in which, Figure 1 represents a longitudinal section
of a cock, or valve according to my invention, and Figure 2 is a cross section thereof
upon the line A. B. Similar letters of reference indicate corresponding parts throughout
the drawings.
In carrying my invention into effect, I employ a truly cylindrical plug A, Figs. 1
and 2 in the accompanying sheet of drawings, to which reference may be had in the
description thereof. Said plug A is arranged so as to slide freely within the barrel B,
and close, or open the ports, or ways formed therein. I may employ adjustable
metal faces for the maintenance of a steam, or pressure tight junction or contact
between said plug A and the barrel B, but I prefer to employ a packing or seating a
of asbestos, "woodite," or other suitable material, said packing being retained by
means of projections either cast upon, or attached to, the barrel B interiorly. With
the exception of the metallic ribs 6¹ 61 61 61, the whole of the working surface
of the plug and barrel is rendered pressure tight, and renewable to compensate the
reasonable wear and tear. The plug A, mounted upon or attached to, a vertical
spindle C. may be moved up or down, by a lever, screw attachment, weight, or any
device that may admit of, and cause said vertical movement, and comply in other
respects with the conditions of the case in which my said invention may be adopted.
A pin D passing through or connected to the spindle C, works within a groove, or
grooves upon the inner surface of the barrel B, so that said plug A may not by
accident, or design be turned round, so that the port E formed therein may be at right

angles, or otherwise out of line, with, the ports, or

ways
barrel B of the cock or valve. Said pin D may be extended, at either or both ends,
so as to protrude through the substance of the barrel B, the slot being in this case
formed to correspond therewith, and I may or may not attach an index, or indices to
one or both extremities of said pin, so that the full travel from "closed" to "open
of the cock or valve, and any fractional parts thereof may be truly and accurately
indicated upon a suitable scale, from the outside. Two collars or other suitable staps,
the lower of which is shown by G. Fig. 1 serve to regulate the vertical movement
of the plug A.
I wish it to be understood, that, although I have shewn a flange upon each side of
the cock or valve according to my invention, in Figs. 1 and 2, I do not confine myself
to the use or application of this form of coupling, but may use a screwed socket, or
sockets, a nipple or nipples as may be best suited to the requirements of the application.
I do confine myself to the manner in which the necessary vertical motion is
imparted to the plug A, nor to the use or non-use of a gland and stuffing box.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is;
In a straightway valve, or cock, the arrangement and employment of a plug A
with vertical movement, and the method of, and means for, packing and preserving
said plug A steam, fluid, and gas tight within the bore of the barrel B, substantially
as herein described, with reference to the accompanying sheet of drawings.
