Complete Specification Accepted, 12th Oct., 1888
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 has for its object improvements in the construction of ordnance and
relates to a new form of joint for joining together the parts of those guns which are
built up of tubes and sections of tubes.
I unite the various sections which constitute the intermediate and outer tubes of
guns by means of conical male and female screw-threads formed on the ends of the
said sections so that any two parts may be screwed together during the process of
shrinking by a very much smaller amount of rotation than would be required if the
screw-threads were parallel as in ordinary cases. By this method of construction I
obtain not only a quicker union of the parts but also greater strength at the joint.
The drawing hereunto annexed shows the application of this form of joint.
A is the inner tube. B the intermediate tube formed of sections B1, B2, B3 united
to one another and to the outer jacket C by the construction of joint above described.
Dated this 9th day of December 1888.

Improvements in the Construction of Ordnance.
1, 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 has for its object improvements in the construction of ordnance and
relates to a new form of joint for joining together the parts of those guns which are
built up of tubes and sections of tubes.
I unite the various sections which constitute the intermediate and outer tubes of
guns by means of conical male and female screw-threads formed on the ends of the
said sections so that any two parts may be screwed together during the process of
shrinking by a very much smaller amount of rotation than would be required if the
threads were parralel as in ordinary cases. By this method of construction I obtain
not only a quicker union of the parts but also greater strength at the joint.
And in order that my invention may he thoroughly understood and carried into
practical effect I shall now refer to the drawing accompanying the Provisional
Specification of this application and to the letters of reference marked thereon.
The said drawing illustrates the application of this form of joint to a gun.
A. is the inner tube. B the intermediate tube formed of sections B1, B2 and 13
united to one another and to the outer jacket by the construction of joint above
described.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
Uniting the various tubes, sections hoops and jacket constituting a built-up gun to
one another by means of male and female conical screw-joints substantially as and for
the purposes described with the aid of the drawings accompanying the Provisional
Specification.
