page_text: I, JOSEPH WERTHEIM of Frankfurt on the Main in the Empire of Germany, do
hereby declare the nature of this Invention to be as follows:-
This Invention has for its object to deaden the noise of sewing machines whilst
in operation and it consists first in mounting the machine upon a metallic support,
independent of the top of the table or stand; secondly in constructing a non-
resonating table or stand top of a frame of zinc or iron and of a perforated or non
perforated plate of lead, or a compound plate of iron & lead; thirdly in a covering
for the table or stand top made of a. compressed fabric, such as is used in book-
binding; and fourthly in a non-sonorous oil tray and drawer. The sewing machine
bed is hinged at its rear side to a longitudinal bearer bar of metal, and rests at its
front edge upon an open frame formed of crossed bars of zinc, cast or wrought iron,
said bearer bar and frame being supported directly on the cast-iron standards of
the stand The top of the table, or stand, is carried by this frame and is consti-
tuted by a plate of perforated sheet metal (preferably non sonorous) or a solid plate
of lead; or a compound plate of iron, rivetted or soldered between two plates of
lead covered with a fabric such as is used in bookbinding, and which is fixed to a
wooden marginal frame at the under side of the table top. The oil tray beneath
the machine and the drawer in the stand are made of wire-cloth or perforated
sheet metal and lined with American cloth.

I JOSEPH WERTHEIM of Frankfort on the Main in the Empire of Germany,
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 :-
This Invention has for its object to deaden the noise of sewing machines whilst
in operation, and it consists first in mounting the machine upon a metallic support
independent of the top of the table or stand; secondly in constructing a non-
resonating table or stand top of a frame of zinc or iron; and of a perforated or
non-perforated plate of lead or a compound plate of iron and lead; thirdly in a
covering for the table or stand top made of a compressed fabric such as is used in
bookbinding; and fourthly in a non-sonorous oil-tray and drawer.
Reference is to be had to the accompanying drawing forming part of this
Specification figure 1 of which represents a longitudinal section figure 2 a cross-
section and figure 3 a plan of the improved sewing machine-stand, figure 4 is a
longitudinal section of the top of the table or stand shown separately.
The bed of the sewing machine A is hinged at its rear side to a longitudinal
bearer bar B of metal and rests at its front edge by studs E upon an open frame
formed of crossed bars D of zinc, cast or wrought iron said bearer bar B and frame D
being supported directly on the cast iron standards C of the stand. The top of
the table or stand is carried by this frame D and is constituted by a plate F of
perforated sheet metal (preferably non-sonorous) or a solid plate of lead or a
compound plate of iron rivetted or soldered between two plates of lead covered
with a compressed fabric H such as is used in bookbinding and which is fixed to a
wooden marginal frame G at the under side of the table top. The oil-tray J
beneath the machine and the drawer K in the stand are both made of wire cloth
or perforated sheet metal and lined with American cloth.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed I declare that what
I claim is;
1. Supporting the bed of a sewing machine on a metallic frame independent of
the table top substantially as described.
2. A table top for sewing machine stands composed of a frame of zinc or iron
and of a perforated or non-perforated plate of lead or iron rivetted or soldered
between two thick lead plates as specified.
3. A covering for the table-tops of sewing-machine stands formed of a compressed
fabric such as used in bookbinding as specified.
4. An oil tray and drawer for sewing-machine tables made of wire cloth or
perforated sheet metal as specified.
Dated this 13th day of September 1886.
