PROVISIONAL SPECIFICATION.
Improvements in Breechloading Ordnance.
I, GEORGE QUICK, of 2, Victoria Mansions, in the City of Westminster, Fleet
Engineer Royal Navy Retired, do hereby declare the nature of this invention to be as
follows:
This invention relates firstly to the application of a band or bands of wire to the
front end of the exterior of that form of gas-ring in which the front part of the
exterior is of cylindrical form and of less diameter than the corresponding cylindrical
rear part. The gas-ring with its wire band or bands is adapted to fit into a recess in
the rear end of the powder-chamber.
Secondly, to the application of a rotating valve-face having a flat bearing surface
to butt up against the rear face of the gas-ring without entering into the said gas-ring
or powder-chamber and secured to the breech-screw by means of the vent-bolt passing
through the axis of the breech-screw, the joints of the said rotating valve-face and
vent-bolt being made gas-tight by means of elastic metal washers.
The drawings hereunto annexed show the general arrangement.
In the drawings Fig. 1 is a sectional elevation showing the form of gas-ring I
prefer to use, but without the wire bands.
Fig. 2 is an elevation of the front face and Fig. 3 an elevation of the rear face of
the gas-ring.
Fig. 4 is a vertical longitudinal section through the rear part of the powder-
chamber and front part of the breech-screw, showing the wire bands on the gas ring
and the revolving valve-face on breech-screw.
Fig. 5 is an elevation of the revolving valve-face and retaining vent-bolt.
In these figures similar letters of reference indicate corresponding parts.

I, GEORGE QUICK, of 2, Victoria Mansions in the City of Westminster, Fleet
Engineer Royal Navy Retired, 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:-
This invention relates firstly to the application of a band or bands of wire to the
front end of the exterior of that form of gas-ring in which the front part of the
exterior is of cylindrical form and of less diameter than the corresponding rear part.
The gas-ring with its band or bands is adapted to fit into a recess in the rear end of
the powder-chamber.
Secondly to the application of a rotating valve-face having a flat bearing surface
to butt up against the rear face of the gas-ring without entering into the said gas-
ring or powder-chamber and secured to the breech-screw by means of the vent-bolt
passing through the axis of the breech-screw, the joints of the said rotating valve-face
and vent-bolt being made gas-tight by means of elastic metal washers.
And in order that my invention may be thoroughly understood and carried into
practical effect 1 will now refer to the drawings accompanying the Provisional
Specification of this application and to the figures and letters of reference marked
thereon.
Fig. 1 is a sectional elevation showing the form of gas-ring I prefer to use but without
the wire bands.
Fig. 2 is an elevation of the front face, and
Fig. 3 is an elevation of the rear face of the gas-ring.
Fig. 4 is a vertical longitudinal section through the rear part of the powder-chamber
and front part of the breech-screw showing the wire bands on the gas-ring and the
rotative valve-face on breech-screw.
Fig. 5 is an elevation of the rotative valve-face and retaining vent-bolt.
In these figures similar letters of reference indicate corresponding parts.

page_text: A is the gas-ring or obturator, "a" is the front part of the exterior of the gas-ring,
and "the rear part of the exterior, "a" being the angular step connecting "a¹"
and "a" "a" is the forward portion of the interior of the gas-ring which is
of greater diameter than the rear portion "a" of the interior and is preferably
coned.
B is the recess for the gas-ring A formed at the rear of the powder-chamber C.
"b" is the recess in front of the angular step "a" to receive a band or bands of
wire """" of any suitable metal or alloy the bands of wire being added for the
purpose of assisting to prevent the escape of gas and also as a means of adjustment to
compensate for the wearing away of the contact surfaces forming the gas-tight joint
or junction of the gas-ring A and rotative valve-face D.
The rotative valve-face D is so mounted in the breech-screw E that the breech-
screw E has a motion independent of the valve-face D whereby the "first motion" of
the breech-screw E is facilitated. F is the bearing in the breech-screw E for the
valve-face D. G is the large-headed vent-bolt for retaining the valve-face D in its
place. This is fixed or locked to the breech-screw E by means of a screwed pin and
recess or other fastening device. H and I are washers for keeping gas-tight the
joints of the said rotative valve-face D and vent-bolt G.
The details of this part of my invention may be considerably varied.
It is obvious that the valve-face and vent-bolt may be formed in one piece and the
whole held in position by a screwed pin the end of which pin would engage in a
groove cut around the said vent-bolt.
By this improved valve-face I am enabled to facilitate the "first motion" of the
breech-screw and consequently minimise the sticking of the breech-screw.
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
(1). The improved forin of gas-ring as described and illustrated by Figures 1, 2, 3
and 4 of the drawings in combination with one or more bands of metal wire as
described and illustrated by Figure 4.
(2). The rotative valve-face substantially as described and illustrated by Figures 4
and 5 of the drawings as a means for facilitating the "first motion" of the breech-
screw.
