Year: 1874

page_text: LETTERS PATENT to Nathan Thompson, of the City of Brooklyn and
State of New York, in the United States of America, but at
present of 23, Southampton Buildings, in the County of Middlesex,
Marine Engineer, for the Invention of ** IMPROVEMENTS IN MEANS
FOR CONNECTING TOGETHER PIPES OR TUBES, AND FOR CONNECTING COCKS,
TUBES, OR PIPES TO OTHER ARTICLES.”
Scaled the 9th June 1874, and dated the 17th April 1874.
PROVISIONAL SPECIFICATION left by the said Nathan Thompson at the
Office of the Commissioners of Patents, with his Petition, on the
17th April 1874.
I, NATHAN THOMPSON, of the City of Brooklyn, and State of New York,
in the United States of America, but at present of 23, Southampton
Buildings,, in the County of Middlesex, Marine Engineer, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN MEANS FOR
CONNECTING TOGETHER PIPES OR TUBES, AND FOR CONNECTING COCKS, TUBES, OR
PIPES TO OTHER ARTICLES," to be as follows:-
The Invention has for its object improvements in means for connecting

page_text: together pipes or tubes, and for connecting cocks, pipes, or tubes, or
to other articles, whereby an easy, secure, and rapid means of connec-
tion and disconnection is obtained. For this purpose I form on the
end of each tube a projecting flange, and on one of such flanges I form
two lugs or cars and a stop. These lugs or cars stand up at right angles
to the flanges, and are each provided with a return piece extending there-
from a short distance in a direction towards the pipe or tube.
In connection with the parts before described I employ a ring which
fits over the pipe or tube having the plain flange. On the upper edge
of this ring I form two inclines, which act in combination with the cars
or lugs on the other pipe or tube. This ring is also by preference
provided with projections which, whilst acting as stops, also serve as
means to facilitate the turning of the ring on the pipe by any suitable
instrument applied thereto.
A recess to receive the packing is preferably formed in the pipe or
tube having the lugs or cars connected thereto.
In connecting together pipes or tubes the ring is passed over its tubo
and rests on the flange thereof, the tube and ring are then passed side-
ways under the projecting parts of the lugs or ears until they arrive at
the stop. To enable this to be done the smallest portions of the inclines
are presented to the lugs or ears; then when the parts are in the proper
relative position with each other the ring is turned round until the
projections thereon come against the lugs or cars. Thus an effective
joint is made by turning the ring through only a portion of a revolution,
and the parts can as readily be disconnected from each other.
If desired the inclines may be made on one of the flanges, and the
lugs or cars may be fixed to the ring.
In connecting cocks, tubes, or pipes to other articles, the parts to be
connected together are provided with similar parts to those above
described.
A spring catch or other means may be employed to prevent the turning
of the ring on the article after the connection has been made.

filed by the said Nathan Thompson in the. Great Seal Patent Office
on the 17th October 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, NATHAN
THOMPSON, of the City of Brooklyn and State of New York, in the.
United States of America, but at present of 23, Southampton Buildings,
in the County of Middlesex, Marine Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventeenth day of April, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Nathan Thompson, Her special license,
that I, the said Nathan Thompson, my executors, administrators, and
assigns, or such others as I, the said Nathan Thompson, my exccutors,
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
MEANS FOR CONNECTING TOGETHER PIPES OR TUBES, AND FOR CONNECTING COCKS,
TUBES, OR PIPES TO OTHER ARTICLES," upon the condition (amongst others).
that I, the said Nathan Thompson, my executors or administrators,
by an instrument 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 bo
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 Nathan Thompson, do hereby declaro
the nature of the said Invention, and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say:
1
The Invention has for its object improvements in means for connecting
together pipes or tubes, and for connecting cocks, pipes, or tubes to other
articles, whereby an easy, secure, and rapid means of connection and
disconnection is obtained. For this purpose I form on the end of cach

page_text: and connected together by means arranged according to my Invention.
Figures 4 and 5 are separate views of the tube 6 and parts fixed thereto;
Figure 6 is a separate view of the tube a and parts fixed thereto, and
Figures 7 and 8 are separate views of the ring c used in combination
with the tubes a and b as herein-after described.
On the end of the tube a is formed a plain projecting flange a', and
on the end of the tube is formed a projecting flange b¹ having two
lugs or ears standing up therefrom at right angles to the flanges, and
being each provided with a return piece 6' extending therefrom a short
distance towards the pipe or tube. These pieces 63 are curved as shown
at Figures 1 and 4, so as to act as stops to the tube a, and secure its
being placed in correct position in relation to the tube b.
In connection with the parts before described I employ a ring c which
fits over the pipe or tube a, and rests on the flange a². On the upper
edge of this ring c I form two inclines c¹ which act in combination with
the cars or lugs 6* on the pipe or tube b. This ring c is also provided
with a projection c³, which whilst acting as a stop also serves as means
to facilitate the turning of the ring c on the pipe or tube a by means of
an instrument & shown by dotted lines in Figure 1.
A recess to receive the packing e is preferably formed in the pipe or
tube b, and such pipe or tube 6 is provided with projections to enable
an instrument f to be placed thereon, as shown by dotted lines in
Figure 1, to hold such pipe or tube firmly whilst turning the ring c in
the act of connecting or disconnecting the tubes a, b.
The ring c has fixed thereto a spring top or catch c³ to prevent the
parts being accidentally turned upon each other when connected
together.
In connecting together pipes or tubes by the means herein-before
described the ring c is passed over its tube a until it rests on the
flange a', the tube a and ring c are then passed sideways in the direction
of the arrow g, Figure 1, under the parts * of the lugs or ears 6' until
the tube a arrives at the curved portions of the parts ³; to enable this
to be done the smallest or lowest portions of the inclines c¹ are presented
to the lugs or ears 6; then when the parts are in the proper relative
position with each other the ring c is by means of an instrument d
turned round in the direction of the arrow h until the projection c² comes
against the lug or car 6 on the left hand side of the Figures 1, 2, 3, 4,

page_text: and 5. Thus an effective joint is made by turning the ring c through
only a portion of a revolution, and the parts can as readily be dis-
connected from each other.
As a modification of the above the inclines c¹ may be made on one of
the flanges, and the lugs or ears 62, 63, may be fixed to the ring c.
In connecting cocks, tubes, or pipes to other articles, the parts to be
connected together are provided with similar parts to those above
described as will be well understood.
Having thus described the nature of my said Invention and the mode
in which I carry the same into effect, I would have it understood that 1
what I claim as my Invention and desire to secure by Letters Patent is
the employment of a ring c and inclines c¹ in combination with parts
a, b, 2, 3, in manner and for the purposes substantially as herein
shown and described.
In witness whereof, I, the said Nathan Thompson, have hereunto 1
set my hand and scal, this Sixteenth day of October in the year
of our Lord One thousand eight hundred and seventy-four.
