I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool, and 6, Bank Street,
Manchester, both in the County of Lancaster, 118 New Street, Birmingham
in the County of Warwick and 31 High Holborn, in the County of Middlesex,
Civil Engineer, do hereby declare the nature of this invention to be as
follows:-
Ordinary embroidery frames consist of two side pieces connected together by
means of two adjustable cross pieces which latter are inserted in narrow slots in
the side pieces, and fastened therein by means of pins inserted in corresponding
holes in the side pieces and cross bars.
Apart from the fact that this mode of fastening did not give the frame the
desired degree of rigidity, embroidery frames made in this way have the drawback
that they can only be adjusted in one direction and within comparatively narrow
limits.
This invention has for its object to remove the above mentioned drawback by an
improved arrangement of embroidery or tambour frame, which allows of the
latter being adjusted in two directions i.e. longitudinally and transversely, whilst
at the same time producing a firmer and more rigid connection of the separate
parts.
With this object, the frame is composed of four side pieces which are made
hollow throughout their entire length or for a suitable distance at both ends, that
is to say are provided with flat recesses and in the latter, extensible strips or bars
perforated at short intervals are inserted. By means of thumb screws passed
through corresponding holes the extensible bars are rigidly fastened to the side
pieces which enclose them in a telescopic manner. The extensible bars of two side
pieces are provided with loops or sockets through which the ends of the other bars
are passed and secured therein by means of thumb screws.
According to requirements the extensible bars may be adjusted more or less
deeply into the recesses and fixed in any position by means of the thumb
screws.
The improved arrangement by which each of the four sides is provided with
bars which can be drawn out, renders it possible to extend the frame in two
directions, namely longitudinally and transversely. As further, the sides are
provided at both ends with extensible bars, they may be extended to a very
considerable extent and consequently frames of this kind may be adjusted within
very wide limits.
The advantage of this is that such a frame may be advantageously employed for
very large as well as for small pieces of work.
The connection of the extensible bars with the side pieces on the oue hand, and
with the loops or sockets on the other hand, by means of screws which can be
screwed tight allows in addition all the parts to be thoroughly and reliably united,
so that the frame consequently presents a rigid resistant body.

forming the fastenings.

1, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool and 6, Bank Street,
Manchester, both in the County of Lancaster, 118, New Street, Birmingham
in the County of Warwick, and 322, High Holborn in the County of Middlesex,
Civil 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 :-
Ordinary embroidery frames consist of two side pieces connected together by
means of two adjustable cross pieces, which latter are inserted in narrow slots in
the side pieces, and fastened therein by means of pins inserted in corresponding
holes in the side pieces and cross bars.
Apart from the fact that this mode of fastening did not give the frame the
desired degree of rigidity embroidery frames made in this way have the drawback
that they can only be adjusted in one direction and within comparatively narrow
limits.
This invention has for its object to remove the above mentioned drawback by an
improved arrangement of embroidery or tambour frame, which allows of the
latter being adjusted in two directions i.e. longitudinally and transversely, whilst
at the same time producing a firmer and more rigid connection of the separate
parts.
With this object, the frame is composed of four side pieces which are made
hollow throughout their entire length or for a suitable distance at both ends, that
is to say are provided with flat recesses and in the latter, extensible strips or bars
perforated at short intervals, are inserted. By means of thumb screws passed
through corresponding holes the extensible bars are rigidly fastened to the side
pieces which enclose them in a telescopic manner. The extensible bars of two side
pieces are provided with loops or sockets through which the ends of the other bars
are passed and secured therein by means of thumb screws.
According to requirements, the extensible bars may be adjusted more or less
deeply into the recesses and fixed in any position by means of the thumb
screws.
The accompanying drawings show various preferred forms of construction of
these improved frames in which the various bars forming each frame are connected
together by means of thumb screws which slide in slots running longitudinally
along the various bars so as to produce a telescopic or extensible arrangement,
whereby the frames may be adjusted to various sizes and then be rigidly secured
by tightening the screws. Sockets at the angles of the frames keep the bars
together at their points, and are each attached to the end of one side bar, whilst
allowing the end of the adjacent side bar to slide through it.
The improved arrangement by which each of the four sides is provided with
bars which can be drawn out, renders it possible to extend the frame in two

page_text: directions, namely longitudinally and transversely. As further, the sides are
provided at both ends with extensible bars, they may be extended to a very
considerable extent and consequently frames of this kind may be adjusted within
very wide limits.
The advantage of this is that such a frame may be advantageously employed for
very large as well as for small pieces of work.
The connection of the extensible bars with the side pieces on the one hand, and
with the loops or sockets on the other hand, by means of screws which can be
screwed tight allows in addition all the parts to be thoroughly and reliably united,
so that the frame consequently presents a rigid resistant body.
Other means than thumb screws may of course if desired be employed for
forming the fastenings.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is-
An embroidery or tambour frame consisting of four sides formed each of
extensible bars working in or against each other, and having means of clamping
them rigidly together, the whole frame being thus adapted to be adjusted as to size
both in height and width substantially as herein before described.
