I MAXIME MAVET METCALF of 11 rue Coquelle Orleans in the Republic of France
Engineer do hereby declare the nature of this invention to be as follows:-
Stands or tables for sewing machines and other stands or supports in which
steadiness is required are provided according to this invention with adjustable feet or
castors enabling the sewing machine or an article of furniture for example to stand
steadily on uneven ground. With this object one or more of the feet or castors is
attached to a rod sliding in a socket in the lower part of the leg or frame of the stand
or support and a set screw or spring or both are employed which enable the foot or
castor to adjust itself automatically to irregularities in the floor or ground and to be
fixed or retained if required in any desired position.
The side frames of a support or table for a sewing machine are preferably made in
the form of the letter M and the transverse frame is made somewhat in the form of the
letter ✗ the upper part of which being in the form of a V is made with the loop at
the bottom of rounded shape so as to afford a convenient foot rest for the machinist
when it is necessary to raise one knee in adjusting the work by hand for example.

Improvements in Legs or Supports for Sewing Machines or Articles
of Furniture and for other like Objects or Articles.
I MAXIME MAVET METCALF of 11 Rue Coquelle Orleans in the Republic of France
Engineer 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 :-
Stands or tables for sewing machines and other stands or supports in which
steadiness is required are provided according to this invention with adjustable feet
or castors enabling the sewing machine or an article of furniture for example to
stand steadily on uneven ground: With this object one or more of the feet or
castors is attached to a rod sliding in a socket in the lower part of the leg or
frame of the stand or support and a set screw or spring or both are employed which
enable the foot or castor to adjust itself automatically to irregularities in the floor or
ground and to be fixed or retained if required in any desired position.
And in order that my said Invention may be fully understood I shall now proceed
more particularly to describe the same and for that purpose shall refer to the several
figures on the annexed sheet of drawings the same letters of reference indicating
corresponding parts in all the figures.
Figure 1 of the accompanying drawings represents in front elevation a sewing
machine stand or table constructed according to this invention with a self-adjusting
foot or feet. These self-adjusting feet illustrated on a larger scale in Figures 2
and 3 are constructed with a stem a a spring b and a screw stop c.
The stem a
is provided at its lower extremity with a castor as represented in the detail
Figure 2 or with a foot or plate as indicated in Figures 1 and 3. The stem a
and spring b are inserted into a socket which may be of any suitable form and
in accordance with the frame of the stand or table to which the self-adjusting foot is
applied.

page_text: When the screw c is loosened the stem a is free to be acted on by the spring
and slides in or out of its socket moving vertically until it is adjusted to any
irregularities in the floor and all the feet bear evenly or come to their proper
bearing. The screw is now to be screwed up tightly and the stand or table is
then perfectly firm and steady. In certain cases the spring may be dispensed with
the screw only being employed or the screw may be removed and a spring only
be employed. It is evident that these self-adjusting feet are applicable to other
articles of furniture and the like with the same advantage as to the sewing machine
stand which is illustrated in the drawing in order to explain this part of the
invention. The other feet of the stand may be provided with suitable castors or
preferably with ball castors as represented in the drawing.
Figures 4 and 5 of the accompanying drawing represent the side frames of the
stand in elevation together with the treadle A pitman B and fly wheel P. These
side frames are made to represent the form of the. letter M and the transverse
franie m m' n n' illustrated in Figure 1'is somewhat in the form of the letter X
the upper part m m³ of which being in the form of a V is made with a loop or
rounded part at the bottom so as to afford a comfortable foot rest for the machinist.
When it is necessary to raise the knee in adjusting or finishing work by hand for
example the foot is placed in the bend mom where it is supported as in a stirrup
without strain or fatigue of the muscles.
The several improvements in legs or supports for sewing machines and the like
herein before may be employed either in combination or separately.
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 -
:-
1. A self-adjusting foot for legs or supports of sewing machines or articles of
furniture and for other like objects or articles constructed with a stem a connected
to a foot or castor, a spring b and a stop screw c all arranged and operating
substantially as hereinbefore described with reference to Figures 2 and 3 of the
accompanying drawings.
2. The construction of frames or supports for sewing machines hereinbefore
described and in particular the part m m¹n n' forming a V shaped support for the
foot of the machinist substantially as hereinbefore described and illustrated in the
accompanying drawings.
