Improvements in Fittings, as Tees, Elbows, Sockets, and the like, used
in connection with Composite or other Tubes.
I, EDWIN WALKER, Engineer, Brook House, Heckmondwike, in the County
of York, do hereby declare the nature of this invention to be as follows.-
-
As 18 well known great care has had to be exercised in screwing composite or
lined tubes into the various fittings, otherwise internal defects are apt to occur
at the joints owing to the tube ends being brought too forcibly against the
lining in fittings, thus twisting, puckering, breaking or other wise damaging the
lining, or splitting the fitting
My invention consists in the internal washening or cushioning of a projec-
tion at the base of the threads and parallel with the same in every fitting, with
any kind of suitable material as leather, asbestos, rubber, or any of their com-
pounds, or other material

Improvements in Fittings, as Tees, Elbows, Sockets, and the like, used
in connection with Composite or other Tubes.
I, EDWIN WALKER, Engineer, Brook House, Heckmondwike, in the County
of York, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
As 18 well known great care has had to be exercised in screwing composite or
lined tubes into the various fittings, otherwise internal defects are apt to occur
at the joints owing to the tube ends being brought too forcibly against the
lining in fittings, thus twisting, pucheng, breaking or otherwise damaging the
lining at the tube ends, or splitting the fittings, in the one case causing the joints
to choke with corrosion, and in the other, leaking joints.-
My invention consists in the internal washering or cushioning of a projec-
tion at the base of the threads and parallel with the same in every fitting, with
any kind of suitable material as leather asbestos, rubber, or any of their com-
pounds or other material The object of this washer or cushion being to avoid
friction between the linings of tubes and the linings of fittings, thus allowing
both to be screwed close without damage to either Also the washer forming a
Beat for the ends of tubes to screw against, the joints are easily made perfectly

page_text: tight close to the lining, thus preventing water or other liquid or gases coming in
contact with the iron of either tube or fittings, and preventing all danger of
rusting on leaking joints.
Such being the nature and object of my invention, I will now describe same
by reference to the annexed sheet of drawings forming part of this specification,
and in which like letters of reference indicate corresponding parts in all figures.
The letters A, are fittings, B, tubes, C, washers, a¹, projections.
Figure 1, 18 a sectional view of tube and washers as applied to a tee.
Figure 2, 18 a sectional view of same as applied to a round elbow.
Figure 3, is a sectional view of a part of a fitting showing projection a¹.
Figure 4, is a plan view showing washer.
Figure 5, 18 a sectional view showing the manner of applying the washer in
sockets or couplings, where the ends of tubes form the projections.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same 18 to be performed, I declare that what
I claim is..
11
The internal washering or cushioning of fittings as tees, elbows, sockets or
couplings and the like, for the protection of the ends and securing the joints of
composite tubes and the like, in the manner and for the purpose substantially
as shewn and described
