Improvements in Washers or Packings.
I THEODORE EUGENE BARTSCH of the firm of Peters Bartsch and Company of
City Road Derby in the County of Derby Manufacturer do hereby declare the
nature of this invention to be as follows:-
My invention relates to that class of washers or packings that may be conveniently
used for insertion into flanges or sockets so that a perfect joint may be made in
pipes and the like and the object is to provide a combined metallic and elastic
washer of simple and economic construction and of a convenient form.
In carrying out my invention I provide a thin flat band or ribbon of soft pliable
metal on which I lay a strip or strips or layers of asbestos hemp rubber graphite
cardboard or other suitable material. The metal and other materials are then bent or
doubled into U shaped section and the ends joined together so as to form an annular,
oval or other shaped washer or packing of the required size or diameter.
metal ring may be formed and bent by any suitable process with a U shaped section
and the elastic material inserted thereafter.

Improvements in Washers or Packings.
I THEODORE EUGENE BARTSOH of the firm of Peters Bartsch and Co. of Derwent
Chambers Derby in the County of Derby Manufacturer do hereby declare the nature
of this invention and in what manner the same is to be performed to be particularly
described in and by the following statement :-
My invention relates to that class of washers or packings that may be conveniently
used for insertion into flanges or sockets so that a perfect joint may be made in pipes
or the like and the object is to provide a combined metallic and elastic washer of
simple and economic construction, and of a convenient form.
Referring to the accompanying sheet of drawings and to the figures and letters of
reference marked thereon:
k
Figure 1 is a view of the metallic portion of the washer or packing showing part of
the ring cut away;
Figure 2 shows the washer or packing in section with the lining inserted;
Figure 3 is a plan of a modification of my washer and packing or lining of the
jointed variety before being bent into shape.
In carrying out my invention I spin or otherwise form a circular, oval or other
conveniently shaped and continuous channel, groove, or double flange from a disc or
plate of thin copper or other suitable metal so that when completed it forms a circular,
oval or other shaped metallic packing of U section A; within the flanges or groove
thus formed I place an internal packing composed of asbestos, hemp, rubber, graphite,
cardboard or any other desirable substance or composition B.
Or I may for my combined packing in the following manner :-
A flat longitudinal band strip or ribbon of thin resilient metal such as copper C
has its ends brought together and jointed being then bent into U shape section; or
I may bend the strip or band of metal into U shape before jointing and afterwards

page_text: form a suitable joint by brazing or any well known process, the inner packing of
asbestos or other material or materials being then inserted as before described.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The washer or packing substantially as hereinbefore described and illustrated by
the figures 1, 2 and 3 in the accompanying sheet of drawings.
Dated this 20th day of March 1890.
