PROVISIONAL SPECIFICATION.
Improvements in Embroidery Frames.
I, GEORGE FREDERICK REDFERN, of the Firm of G. F. Redfern & Co., The
General Patent Office, No. 4, South Street, Finsbury, in the County of London,
Patent Agents, do hereby declare the nature of this invention (a communication
to me by Krautheimer & Co., of Promenade Strasse, Fuerth, Bavaria, in the
German Empire, Manufacturers) to be as follows:-
This invention relates to improvements in what are known as embroidery
tambour frames, that is to say, frames for stretching fabric to be embroidered.
These frames consist of two concentric rings one fitting within the other.
The material to be stretched is placed over the smaller of the two rings and the
larger or outer ring is then passed over the material and the inner ring whereby.
the material is tightly stretched between the two rings.
In practice it has been found that with certain classes of fabric a firm grip
cannot be obtained and as a consequence the material is liable to slip and become
loose.
The object of the present invention is to obviate this objection and to this
end the periphery of the inner ring is suitably roughened. I have found in
practice that a good roughened surface for my purpose is obtained by channelling
or corrugating the said surface.
I, GEORGE FREDERICK REDFERN, of the Firm of G. F. Redfern & Co., The
General Patent Office, No. 4, South Street, Finsbury, in the County of London,
Patent Agents, do hereby declare the nature of this invention (a communication
to me by Krautheimer & Co., of Promenade Strasse, Fuerth, Bavaria, in the
German Empire, Manufacturers) and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
This invention relates to improvements in what are known as embroidery

These frames consist of two concentric rings one fitting within the other.

page_text: The material to be stretched is placed over the smaller of the two rings and the
larger or outer ring is then passed over the material and the inner ring whereby
the material is tightly stretched between the two rings.
In practice it has been found that with certain classes of fabric a firm grip
cannot be obtained and as a consequence the material is liable to slip and become
loose.
The object of the present invention is to obviate this objection and to this
end the periphery of the inner ring is suitably roughened.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing in which:-
Figure 1 is a plan view of my improved stretching frame, and
Figure 2 is a section on the line 2-2 of Figure 1 showing a piece of fabric in
position.
Figure 3 is a plan view of the inner ring; and,
Figure 4 is a section on the line 4-4 of Figure 3.
a, b are the outer and inner rings respectively and c, c are a series of grooves
formed around the periphery of the said inner ring which grooves are found
in practice to roughen the surface of the ring b sufficiently to enable a good hold
to be obtained.
If desired, however, the surface of the ring 6 may be corrugated or it may be
roughened in any other suitable manner..
It will be readily understood that when a piece of fabric is stretched over the
ring b and the outer ring a is placed in position as shown in Figure 2, the said
fabric will be firmly held.
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. An embroidery frame composed of two concentric rings having the outer
periphery of the inner ring grooved or otherwise roughened, substantially as,
and for the purpose, described.
2. The manufacture and use of embroidery frames, substantially as herein before
described and illustrated in the accompanying drawing.
