JESSE H. ALLISON, OF EL PASO, TEXAS, ASSIGNOR OF ONE-HALF TO L. G. HADLEY, OF
EL PASO, TEXAS.
PACKING-GASKET.Specification of Letters Patent. Patented Nov. 16, 1920.
Application filed lTuly 26, 1919. Serial No. 313,518.To all whom it may concern:
Be it known that I, JESSE H. ALLisoN, a
citizen of the United States, and a resident
of the city of El Paso, in the county of El
5 Paso, State of Texas, have invented certain
new and useful improvements in Packing-
Gaskets; and I do hereby declare that the
following is a full, clear, and exact descrip-
tion of the same, reference being had to the
10 accompanying drawings, and to the numer-
als of reference marked thereon, which form
a part of this specification.
This invention relates more particularly
to an improved type of a one piece metal
15 gasket or packing ring adapted to insure a
tight joint between two pipes the adjacent
ends of which are flanged and bolted to-
gether.
It is an object of this invention to provide
20 a one piece metal pipe-joint or gasket.
Another object of the invention is the con-
struction of a unitary metal gasket, swaged
to afford a compressible peripheral bead.
A further object of the invention is to con.
25 struct a one piece metal pipe-joint having
an integral internally grooved ring formed
thereon and adapted to be compressed be-
tween the adjacent flanged ends of pipes,
when said pipes are bolted together.
30 It is an important object of this invention
to provide a non-leaking joint between con-
nected pipes by the use of a soft metal
gasket which is adapted to be shortened as
an integral grooved circumferential flange
35 thereof is pinched between the adjacent ends
of said pipes as they are drawn together.
Other and further important objects of
this invention will be apparent from the
disclosures in the drawings and specifica-
40 tion.
My invention (in a preferred form) is
illustrated in the drawings and hereinafter
more fully described.
On the drawings:
45 Figure 1 is a side elevation of a gasket
embodying the principles of the invention.
Fig. 2 is an'end view thereof.
Fig. 3 is a longitudinal section of two con-
nected pipes showing the gasket in position
50 before compression thereof.
Fig. 4 is a similar section with the pipe
flanges drawn together to pinch the grooved
gasket ring to form a non-leaking joint.Fig. 5 is a side elevation of the compressed
gasket removed from the pipes. 55
As shown on the drawings
The reference numerals 1 and 2, indicate
two alined pipes, having integrally formed
on the adjacent ends thereof apertured
flanges .3 and 4, respectively. Engaged 60
through the registering apertures of the
pipe flanges 3 and 4 are bolts 5 adapted to
draw the pipes together when the nuts 6, of
said bolts are threaded on the bolts.
To form a tight non-leaking pipe-joint be- 65
tween the connected pipes 1 and 2, a' soft
metal one piece gasket, coupling or packing
member is engaged in and between said
pipes as shown in Fig. 3. The gasket is
made of copper, brass or other suitable 70
metal and comprises a cylindrical sleeve or
bushing 7, slightly tapered toward each end.
The sleeve 7, is swaged to provide an in-
tegral circumferential bead, rib or ring 8,
intermediate the ends thereof. The ring 8, 75
is formed with an inner circular groove 9.
When the gasket is placed in position the
tapered ends thereof are projected into the
adjacent ends of the pipes 1 and 2, leaving
the gasket ring 8, disposed between the pipe '80
flanges 3 and 4, as shown in Fig. 3. The
ends of the sleeve 7, are slightly tapered to
insure a tighter fit with the inner surfaces
of said pipes when they are drawn together.
With the one piece grooved metal gasket 85
or union in place as described the pipes are
drawn together by threading the nuts 6
farther onto the bolt 5, thereby simulta-
neously shortening the gasket by pinching
and forcing the opposite sides of the gasket 90
ring 8, toward each other until the groove
9, substantially is closed as shown in Fig.
4. The ring 8, is thus reduced by compres-
sion to form the flattened packing flange 10,
as shown in Figs. 4 and 5. The pipe-joint 95
formed as described affords an air and liq-
uid tight union or connection for the pipes
1 and 2.
It will of course be understood that the
one piece soft metal gasket may be con- 10'
structed in various different forms other
than the cylindrical form shown and de-
scribed.
I am aware that numerous details of con-
struction may be varied through a wide 10
range without departing from the principles1,359,142.
