Improvements in and relating to Steam Joint Packing.
We, EDWARD LIVINGSTON PERRY and WILLIAM GREEN WINANS, Manu-
facturers, and citizens of the United States of America, residing respectively at
No. 265 Graham Avenue in the City of Paterson, County of Passaic and State of
New Jersey, and at No. 40 West 20th Street, in the City, County and State of
New York, United States of America, 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 :-
Figure 1 of the drawings represents a view of our improved steam joint packing
previous to the ends being connected together by the tubular coupling.
Figure 2 represents a plan view partly in section showing the two ends of the
packing connected together.
Figure 3 a cross section through the packing.
Figure 4 a similar view showing the packing and coupling-tube compressed.
Figure 5 a detail view in perspective of the coupling tube.
The present invention has relation to that class of steam packing or gaskets for
hand holes, man holes, cylinder-heads, and in other places where a packing of this
description would be found useful, and it consists in a packing constructed sub-
stantially as shown in the drawings and hereinafter described and claimed.
In the accompanying drawings, A, represents the outer covering of rubber
compound or other suitable elastic material, and, B, the core of cotton-duck or
other well-known woven fabrics wound in layers to form the core of the desired
size.
It is necessary for the more perfect construction of the packing and to render it
sufficiently strong to resist the pressure of steam and prevent blowing out, to form
the core of a woven fabric which possesses the requisite strength and durability for
the purpose intended.
The packing above-described may be round, oval, square, or of any other
preferred shape in cross-section, and any diameter as found most desirable, such
changes coming within ordinary mechanical skill and we therefore reserve the right
to make the same without departing from the principle of our invention.
In order to secure the compression of the packing more readily, the core, B, is
made hollow which also provides means for attaching the ends of the hollow
coupling tube, C, to join the two ends of the packing together, after which the joint
thus made is covered with a picce of suitable material.
The coupling tube is preferably made of metal but other material may be used,
and is made hollow to enable it to be compressed with the packing.
Although it is considered materially advantageous to have the coupling in the
form of a hollow tube, a solid coupling may be used, but possibly not with as good
results.
Having now particularly described and ascertained the nature of our said inven-
Lion and in what manner the same is to be perforined, we declare that what we
claim, is :-
A steam-joint packing consisting of a hollow core of cotton, duck, or other woven
fabric, and a covering of elastic material, and a coupling, the ends of which enter
the ends of the packing, substantially as and for the purpose specified.
