JOHN E. SHUTT, OF GANADO, TEXAS.GASKET
No. 841,059.
To /i whomm it May concern:
Be it known that I, JOHN E. SIIUTT, a citi-
zen of the United States, residing at Ganado,
in the county of Jackson and State of Texas,
5 have invented a new and useful Gasket, of
which the following is a specification.
This invention relates to gaskets or pack-.
ing-rings for pipe-joints and the like, and is
more particularly an improvement upon an-
i o other application filed by me in the United
States Patent Office and bearing Serial No.
226,4J2.
Ordinarily gaskets and packing-rings are
manufactured in standard sizes, and when
15 making a connection if the W'orkman-does not
possess. the proper size. of gasket it is neces-
sary to delay the work.until a gasket can be
obtained from the shop. In view of this
difficulty it is the essential object of the pres-
20 ent invention to provide for the production
of gaskets by the workman whenever de-
sired without regard to the size and charac-
ter of the joint..
With these and other objects in view the
25 present invention consists in tie coinbina-
tion and arrangement of parts hereinafter
more fully described, show-n in the accom-
panying drawings, and particularly pointed,
out in the appended claim, it being under-
30 stood that changes in the form, proportion,
size,- and minor details may be-made within
the scope of the claim without departing
from the spirit -or sacrificing any of the ad-
vantages 'of the invention.
35 In the drawings, Figure 1 is a view of a
length of material from which one of the
'gaskets of the present inention is formed.
Fig. 2 is a sectional view of a pipe-coupling'
having a gasket -applied thereto in accord-
40 ance with the present invention, with the
members of the joint in readiness to be
tightened. Fig. 3 is a cross-sectional view of
the joint with the gasket in elevation prior to
tightening of the coupling members. Fig. 4
45 is a view similar to Fig. 2 after the coupling
members have been tightened and the gas-
ket thereby compressed. Fig. 5 is a detail
perspective view of the gasket before being
compressed. Fig. 6 is a detail perspective
50 view of' the gasket after being compressed.
Fig. 7 is a view of a modification. Fig. 8 is a
sectional view thereof preparatory to tight-
ening the joint. Fig. 9 is a similar viewPatented Jan. 8,.1907.
showing the joint tightened and the gasket
flattened. 55
Like characters of reference designate cor-
responding parts in all of the figures of the
drawings.
For. the purpose of illustrating the applica-
tion of the present invention an ordinary 6o
form of pipe joint or coupling has been shown
in the accompanying drawings and includes
opposite coupling members 1 and 2. The
member 2 has a collar 3 embracing the same
and swiveled thereon with its front end por- 65
tion projected beyond the coupling member
2 and internally threaded to engage the ex-.
ternally-threaded portion of the coupling
member 1. As usual, the coupling member
2 has a forwardly-directed cylindrical flange o
4, embracing the top thereof, which; flange is
embraced by the adjacent end of the coupling
member 1 when the two members are assem-
bled.
. In carrying out the present, invention'a 75
suitable length 5 of wire, as shown in Fig. .,
is cut. from a roll or spool of wire, and'this
length of wire is wound a suitable number 9f
times around the flange 4 of the coupling
member 2, as best indicated in Fig. 3 of the 'So
drawings. After the. gasket has thus been
completed and fitted in place the coupling
member 1 is associated with the swiveled
ring 3, and the latter is turned so as toydrawv
the- two coupling members together, and 8,
thereby compress the coils of the wire, into a
flat' gasket, completely -filling the space be-
tween the two coupling members,-the flange
4, and the rino 3. The wire 5 should,.beof
lead or any 'of its alloys, so as to be suffi- 90
ciently soft and pliable to enable the con-
venient severing of the same and winding of
the severed portion into a spiral gasket and
also to permit of the contiguous' coiled por-
tions flowing into one another under 'the 95
compressionincident to the tightening of the
joint.. By preference the ends:;of the wire
are severed obliquely in reversedirections in
order that the inner coiled portion of the
gasket may snugly hug the flange 4 'and in ioo
order that the outer end of the wire may
merge into the outer face of the adjacent
coil. The difference between,_ the gasket
prior to being compresed and 'after being
compressed will be readily appreciated by- 105
reference to Figs. 5 and 6, wherein it will beSpecification of Letters, Patent.
