Improvements in Extensible Tables.

page_text: Improvements in Extensible Tables.
I, WILLIAM SCOTT MORTON, of The Cedars, North Hill, Highgate, in the County
of Middlesex, Decorative Architect, do hereby declare the nature of this invention
to be as follows, that is to say:-
'
My said invention relates to extensible tables and has for its object to improve the
construction of the parts of such tables, so as to render them lighter, more compact
when contracted, and capable of being more conveniently packed for storage or
transit.
For carrying the outer parts of a table when extended I provide light steel bars
which are fitted to work in steel guide boxes or frames fixed to the under side of the
part of the table from which the movable parts proceed. And where extra exten-
sibility is required, I provide similar steel bars to work in guide boxes or grooves
at the outer ends of the first bars. I connect the outer steel bars by diagonal
tie rods; and fix legs to them at the ends, and also at other parts if required,
the legs being fixed in any convenient way but preferably so as to admit for
detachment for packing or transit purposes.
A table may be made with single or double extensible parts for one or both ends;
and the usual arrangement of longitudinal screw spindle may be fitted for extend-
ing or contracting, separate screw spindles being by preference fitted when the
table is provided with extensible parts for both ends.

I, WILLIAM SCOTT MORTON, of The Cedars, North Hill, Highgate, in the County
of Middlesex, Decorative Architect, 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, that is to say :-
My said invention relates to extensible tables and has for its object to improve
the construction of the parts of such tables, so as to render them lighter, more com-
pact when contracted, and capable of being more conveniently packed for storage
or transit.
For carrying the outer parts of a table when extended I provide a pair of light

page_text: metal bars or slides fitted to work in metal guides or frame bars fixed to the under-
side of the part of the table from which the movable parts proceed. Similar
metal bars or slides are provided to work in guides on the first movable bars or
slides (and in a similar way other bars or slides may be provided to work in con-
nection with the second bars this arrangement being extended if required). The
outermost pair of metal bars or slides are connected by diagonal tie rods and have
legs fixed to them, and the parts of the table are extended and contracted by screw
spindles telescopically arranged as usual.
And in order that my said invention and the manner of performing the same may
be properly understood I hereunto append a sheet of explanatory drawings, to be
hereinafter referred to, and showing an extensible table as made with my improve-
ments.
Figure 1, of the drawings is a side elevation. Figure 2, is a transverse vertical
section. Figure, 3, is a plan with the top removed. Figures, 4, 5, and 6, are
respectively a side elevation, a transverse vertical section, and a plan of details.
Figure, 7, is a transverse vertical section of a separate modification of a detail. In
these drawings the same reference letters are used to mark the same or like parts
wherever they are repeated.
The stationary part, A, of the table is formed with a transverse frame piece, B,
at one end; and this frame piece, B, is made with flanged downwardly projecting
parts, C, to which the table legs, D, at that end are bolted. The frame piece, B,
is made with guide boxes, E, at each side and to the outer side of each guide box
a light steel or other metal bar, G, is fixed, each bar being formed with dovetail
guide grooves on its inner side. The bars, G, form guides on which slide other metal
bars or slides, J, and K, for carrying the outer parts of the table when extended.
In the case of a table which (like the example shown in the drawings) is capable
of being extended nearly to three times its closed size the first pair of sliding bars, J.
The second
are made with parts to fit the dovetail guides, H, of the fixed bars, G.
pair of sliding bars, K, are similar to the fixed guide bars, G, and slide in dovetail
guides on the inner sides of the second pair of bars, J. The outermost ends of the
sliding bars, K, are fixed to boxes, L, on the outermost extended part of the table,
and the bars, K, are connected by diagonal tie rods, M, and a transverse tie rod, N,
The innermost ends of the sliding bars, J, are connected together by a transverse
tie rod, P. The parts of the table are extended and contracted by screwed
spindles, R, T, and U, acting telescopically; for example, the spindle, R, of the
stationary part of the table has its outer end held in a bracket, S, on the frame, B,
and is made with a square part to which a key or handle may be applied, and the
spindle is screwed externally. The spindle, R, screws into the spindle, T, of the
intermediate parts of the table, and the spindle, T, is tubular and is screwed inter-
nally for a short part of its length. The intermediate spindle, T, is fixed to the
transverse tie rod, P, of the intermediate sliding bars, J. The intermediate
spindle, T, is also screwed externally, and screws into an outer tubular spindle, U,
which is screwed internally for a short part of its length. The spindle, U, is fixed
tie rod, N, and to a bracket, V,
transverse
on
a
transverse
to the
frame piece, W, similar to that of the stationary part of the table.
By means of the action of these spindles, R, T, and U, the parts of the table may
be extended or contracted the ends of the guide bars, G, J, and K, entering within
the guide boxes, E, and L, by which they are steadied.
A second set of movable bars may be arranged to be extended in the opposite
direction from the same stationary part; or the movable parts may be arranged to
extend between two opposite end parts like what has been referred to as a stationary
part.
The bars, G, J, K, may be shaped as shown in Figure 7, instead of as shown in
Figure, 5.
The guide bars, G, J, and K, may be made of steel or of any other suitable metal
such for example of what is known as delta metal, the dimensions of the parts being
modified to suit the particular metal employed if necessary.

page_text: Having now particularly described and ascertained the nature of my said
invention and the manner in which the same is to be performed, I declare that
what I claim is:-
An extensible table made with a metal framework and having light metal bars
or slides fitted to work in metal guides in fixed or movable bars, the parts being
constructed and operating substantially as hereinbefore described. and as shown
in the accompanying drawings.
