Improvements in Portable Collapsable Tables, applicable for
Surgical-operating Tables and other purposes.
1, FREDERIC BOWREMAN JESSETT, of 16 Upper Wimpole Street, Cavendish
Square, in the County of Middlesex, Surgeon, do hereby declare the nature of this
invention to be as follows:-
The object of this invention is mainly to provide a table for surgical operations
or other purposes which shall weigh but little and which can be packed up into
small compass to render it readily portable.
One half or thereabouts of the length of the table is formed of an oblong rect-
angular frame which has legs attached to its two ends by hinge joints so that when
the table is out of use they may be turned into a position parallel with the sides of
the frame or when the table is to be set up they may be turned into positions at
right angles to the frame and be then retained by knuckle jointed links. In order
that the legs may be made equal or nearly so to the length of the frame the two
legs at one end of the frame are set as far apart as practicable whilst the two legs
at the other end of the frame are set at a less distance apart and so that when the
table is folded up they may lie just between the others.
The rectangular frame is made telescopic, that is, it has within it a second frame
which can be drawn out at one end and be made to form an extension of the main
frame.
At its outer end this second frame has legs attached to it by hinge joints
and knuckle jointed links are provided for holding the legs fast when the
extension piece has been drawn out and the legs have been turned downwards
to support it.
When the extension piece is not required to be drawn out the legs of this
piece can be turned into a position parallel with the frame and then the exten-
sion piece and its legs can be slidden endwise so as to bring them within the main
frame.
The top of the table is divided crosswise into three divisions. The middle
division is fixed above that end of the main rectangular frame out from which the
extension piece can be drawn. The division which covers over the remainder of
the frame is jointed to the end of the central division so that it can be turned
upwards into a more or less inclined position to support a patient's head and can be
held at any desired angle by legs jointed to it being made to enter one or other of
a series of notches in the top of the two side pieces of the main rectangular
frame.
The third division of the top of the table is hinged by short lengths to the
opposite end of the central division-these allow of the third division of the top
being turned either into a position to lie flat above the other two divisions of the
top when the table is folded up and out of use or if the table is in use and
the extension piece drawn out it can lie above the top of the extension piece or if
the extension piece is not drawn out it can be allowed to hang down at the end
of the table.
For ordinary purposes the top is only divided into two divisions the portion on
the main table being fixed, while the second division is hinged like the third.
division described above.
Each division of the top of the table is formed of an outer wooden frame covered
over with a covering of thin tough perforated wood.

Improvements in Portable Collapsable Tables, applicable for
Surgical-operating Tables and other purposes.
1, FREDERIC BOWREMAN JESSETT, of 16 Upper Wimpole Street, Cavendish
Square, in the County of Middlesex, Surgeon, 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:-
The object of this invention is mainly to provide a table for surgical operations
or other purposes which shall weigh but little and which can be packed up into
small compass to render it readily portable.
The drawing annexed shews various views of a table constructed according to
my invention.
Figure 1 is a perspective view of the table with one end of the top of the table
turned upwards into an inclined position,
Figure 2 is a perspective view of the table partly closed, and
Figure 3 an underside view of the table completely closed.
One half or thereabouts of the length of the table is formed of an oblong
rectangular frame A which has legs B attached to its two ends by hinge joints so
that when the table is out of use they may be turned into a position parallel with
the sides of the frame as shewn at Figure 3 or when the table is to be set up they
may be turned into positions at right angles to the frame and be then retained
by knuckle jointed links C. In order that the legs may be made equal or nearly
so to the length of the frame the two legs at one end of the frame are as shewn
in Figure 3 set as far apart as practicable whilst the two legs at the other end of
the frame are set at a less distance apart and so that when the table is folded up
they may lie just between the others.
The rectangular frame is made telescopic, that is it has within it a second
frame D see Figure 2 which can be drawn out at one end and be made to form an
extension of the main frame A.
At its outer end this second frame has legs E attached to it by hinge joints and
knuckle jointed links I are provided for holding the legs fast when the
extension piece has been drawn out and the legs have been turned downwards to
support it.
When the extension piece D is not required to be drawn out the legs of this
piece can be turned into a position parallel with the frame and then the extension
piece and its legs can be slidden endwise so as to bring them within the main
frame.
The top of the table is divided crosswise into three divisions G H I. The
middle division H is fixed above that end of the main rectangular frame A out
from which the extension piece D can be drawn. The division I which covers
over the remainder of the frame A is jointed to the end of the central division so
that it can be turned upwards into a more or less inclined position to support a
patient's head and can be held at any desired angle by legs J jointed to it being
made to enter one or other of a series of notches in the top of the two side pieces
of the main rectangular frame A.
The third division G of the top of the table is hinged by short lengths to the
opposite end of the central division-these allow of the third division of the top
being turned either into a position to lie flat as shewn at Figure 2 above the other
two divisions of the top when the table is folded up and out of use or if the table.
is in use and the extension piece drawn out it can lie above the top of the
extension piece as shewn at Figure 1 or if the extension piece is not drawn out it
can be allowed to hang down at the end of the table.
For ordinary purposes the top is only divided into two divisions the portion on
the main table being fixed while the second division is hinged like the third
division described above.

page_text: Each division of the top of the table is formed of an outer wooden frame covered
over with a covering of thin tough perforated wood.
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 portable collapsable table composed of a frame A having a pair of legs
jointed to it at each end, the legs in one pair being at a greater distance apart
than in the other, and of a sliding extension piece provided with legs at its outer
end and of a top cover in sections jointed together one fixed to the frame A whilst
the section which is to be supported by the sliding extension piece is made
capable either of being turned back over the section fixed to the frame A when
out of use or allowed to hang down at the end of the table when the extension
piece is not drawn out substantially as described.
2. A portable collapsable table constructed substantially as hereinbefore:
described.
