JOSEPH SHAW, of Lockwood, near Huddersfield, in the County of York, Brass
Finisher and Mill Furnisher. A NEW OR IMPROVED UNION' OR JOINT FOR
PIPES."
My improved union or joint for pipes is composed of two parts, each part con-
sisting of a flanged nut or collar, the flanges having holes for the insertion of
bolts or screws. On the face of one part is a projection, which enters a corre-
sponding recess on the other part, forming a gland or tight joint without the use of
packing.
The two parts of the union are screwed or otherwise fastened on to the ends of
the pipes to be joined, and are then placed together and fastened by bolts passing
through both flanges, and secured by nuts on the end thereof.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Joseph Shaw in the Great Seal Patent Office on the 16th October
1877.
JOSEPH SHAW, of Lockwood, near Huddersfield, in the County of York, Brass
Finisher and Mill Furnisher. "A NEW OR IMPROVED UNION' OR JOINT FOR
PIPES."
This Invention consists in making a
"' union
or joint for pipes so that they can
be readily applied and adjusted, and my improved "union" or joint consists of two
nuts or collars with flanges, the said flanges having holes for the insertion of bolts

page_text: or screws.
On the face of one part is a projection, which enters a corresponding
recess on the other part, forming a gland or tight joint without the use of
packing.
The two parts of the union are screwed or otherwise secured on to the ends of the
pipes to be joined, and are then placed together and fastened by bolts passing through 5
both flanges, and secured by nuts on the ends thereof.
This Invention will be better understood by reference to the accompanying
Sheet of Drawings, wherein Fig. 1 represents an elevation, and Fig. 2 a section of
my improved "union" or joint.
A is a nut which is screwed or otherwise fastened on to the end of a pipe intended 1
to be joined, and B is a tapered projection, which fits into a corresponding recess
formed in another nut C; D are flanges placed upon each nut, so that the two nuts
can be drawn together by bolts E, thereby making a perfectly tight joint without the
aid of packing.
The flange may either be cast in one piece with the nut, or it may be separate 1
and loose thereon, as herein shewn, and in the using of them a fast and loose flange
may work together.
Having thus described the nature of my Invention, and shewn the manner in
which the same is to be performed, I would have it understood that I do not claim
as my Invention any of the parts separately, but what I consider to be new and 2
therefore clain as my Invention is, the combination of the several partsforming a
complete "union" or joint, for the purpose herein shewn and described.
In witness whereof, I, the said Joseph Shaw, have hereunto set my hand and
seal, this Twelfth day of October, in the year of our Lord One thousand
eight hundred and seventy-seven.
Signed, scaled, and delivered by the
within-named Joseph Shaw, in the
presence of
JOSEPH ALLEN BOCOCK.
