page_text: LETTERS PATENT to Arnold Budenberg, of the Firm of Schäffer and
Budenberg, of Manchester, in the County of Lancaster, for the Inven-
tion of "IMPROVEMENTS IN JOINTS OF PIPES OR TUBES."-A communication
from abroad by Bernhard August Schäffer and Christian Frederich
Budenberg, of Buckau, Magdeburg, in the Kingdom of Prussia.
Sealed the 17th January 1868, and dated the 20th July 1867.
PROVISIONAL SPECIFICATION left by the said Arnold Budenberg at
the Office of the Commissioners of Patents, with his Petition, on
the 20th July 1867.
I, ARNOLD BUDENBERG, of the Firm of Schäffer and Budenberg, of Man-
chester, in the County of Lancaster, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN JOINTS OF PIPES OR TUBES," (a communication,
to be as follows:-
The object of the improvements is to obtain a close joint to pipes or tubes
capable of being set at various angles. For this purpose the parts of the
pipes or tubes at the junction are of a spherical form, one part of such sphere
forming part of one pipe or tube, and the other part of such sphere forming
part of the other pipe or tube. The parts of these spheres where the junction
takes place are inclined, by preference to an angle of 45 degrees with the
axis of the parts of the pipe, are and fitted with leather or other packing.
[Prise 8d.]

page_text: These parts are held together by a screw clip. By these means the same
parts may be held together so as to form a continuous straight line at an
angle of 45 degrees or at other intermediate angles.
SPECIFICATION in pursuance of the conditions of the Letters Pateut, filed
by the said Arnold Budenberg in the Great Seal Patent Office on
the 20th January 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ARNOLD
BUDENBERG, of the Firm of Schäffer and Budenberg, of Manchester, in the
County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of July, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Arnold Budenberg, Her special licence that I, the said Arnold
Budenberg, my executors, administrators, and assigns, or such others as
I, the said Arnold Budenberg, 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 "IM
PROVEMENTS IN JOINTS OF PIPES OR TUBES," a communication to me from abroad
by Bernhard August Schäffer and Christian Friedrich Budenberg, of Buckau,
Magdeburg, in the Kingdom of Prussia, upon the condition (amongst
others) that I, the said Arnold Budenberg, 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 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 Arnold Budenberg, 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, that is to say:-
The object of the improvements is to obtain a close joint to pipes or tubes
capable of being set at various angles. For this purpose the parts of the
pipes or tubes at the junction are of a spherical form, oue part of such sphere

page_text: part of the other pipe or tube. The parts of these spheres where the junction
takes place are inclined, by preference to an angle of 45 degrees with the
axis of the parts of the pipe, and are fitted with leather or other packing.
These parts are held together by a screw clip or other suitable meaus.
But that the Invention may be fully understood 1 will by the aid of the
accompanying Drawing proceed to describe means pursued by me in
carrying the same into effect.
DESCRIPTION OF THE DRAWING.
Figures 1 and 2 show the cuds of two portions of pipes or tubes in section,
each having a portion of a hemispherical swelling or boss to it adapted to fit
one to the other, so that when they are placed together they form in com-
bination a joint adapted to move on a centre and at an angle to the axis of
the straight portion of each pipe or tube as illustrated by Figures 3 and 4.
In each of the Figures of the Drawing the same letters refer to corresponding
parts. A shows a portion of one pipe or tube having its end B swelled
out, into a portion of a hollow sphere with the end B' of it inclined at an
angle to the axis of the pipe or tube. This angle may be varied, but the
angle of 45° is preferred for general purposes. A recess is formed in the
end B of this pipe or tube A into which may be placed leather or other
packing suitable for making a tight joint. The other portion of the sphere
is formed on the end of another pipe or tube C, whose end D is also inclined
at D at an angle to the line of axis of the pipe or tube. The inclined end of
this pipe or tube has a projection d formed upon it adapted to pass into the
recess b, in the end B' when the ends of two of such pipes or tubes are
brought together, and thereby compress the leather or other packing therein.
Two such pipe or tube ends may be held together for use by various means:
that shown in Figures 1, 2, 3, and 4 being by means of a bolt and nut E
forming a centre pin coincident with the centre of the sphere and at right
angles to the line of junction of the parts of it, so that pipes or tubes with
ends thus formed may be free to move round upon such bolt to assume
various angles to each other. In the above Figures the angle of junction
is 45° and the axial lines of the pipes or tubes, by turning the pipes or
tubes on the centre pin, may be varied one to the other from a straight line
to right angles, or to any intermediate angle.
The above described general arrangement of the Invention shows a simple
form of connecting the ends of two pipes or tubes together, but I do not
confine myself to this method. For large pipes or tubes flanges may be

page_text: formed on their hemispherical ends, and these may be held together by bolts
and nuts, slotted holes being made in the flanges for the bolts to allow of
adjustment or alteration of the angle of the pipes or tubes to each other
as shown in Figures 5, 6 and 6*.
An external strap or clip F may also be employed as shown in Figures 7 and
8, or other modifications of such form may be employed. I would also state
that I do not confiue myself to the exact form of recess and projection for
packing and fitting as shown in Figures 1 and 2, as any of the ordinary
means for forming tight joints which will at the same time act as a guide for
the concentric movement of the respective parts of the hemisphere on each
other may be used. In order to facilitate the coupling up of several lengths
of piping and to accommodate the peculiar motion of this joint when set at
varying angles, the connecting flanges at the other end of such pipes or tubes
may be made with slotted bolt holes as stated to allow of the rotation on its
own axis of each pipe, or I use couplings or stuffing boxes and sliding sockets
as shown in Figure 9, whereby the straight and angular joints are enabled
to be brought together and connected up as may be required, or a series of
these joints may be used in combination. Joints made as above described
are applicable to pipes and tubes for a variety of purposes and are particularly
suitable for steam, water, gas and other liquids and fluids.
Having now described my Invention and means which I adopt for carrying
the same into effect, I would have it understood that I do not confine
myself to the precise details shown and described, as the same may be varied
without departing from the peculiar character of the Invention; but what
I do claim is the method of forming the ends or joints of pipes or tubes, so
that such pipes or tubes may be connected together at varying angles in
manuer substantially as explained.
In witness whereof, I, the said Arnold Budenberg, have hereunto set
my hand and seal, this Seventeenth day of January, in the year of
our Lord One thousand eight hundred and sixty-eight.
ARNOLD BUDENBERG. (L.S.)
