PROVISIONAL SPECIFICATION.
An Improved Extensible Bedstead.
I, MARY ANN CUNNINGHAM of 3 Clapton Square, London N.E., Widow,
do hereby declare the nature of this invention to be as follows :—
An ordinary iron bedstead is fitted with a bar at each end underneath the bar of
the ordinary horizontal frame. This additional bar is made with a V shaped
groove faced with gun-metal or other hard non-corrosive material. An extra frame
is provided having two legs on one side but not on the other. The end bars of
this frame are constructed to slide in the V shaped grooves of the bars above
mentioned. The inner extremities of the end bars of the sliding frame are
constructed with convenient bearings so as to run with little friction in the grooves.
These bearings may be simple solid projections or small wheel or ball bearings.
The two legs of the sliding frame are fitted with castors. The bedstead has and
the additional frame can be pulled out when required and support an additional
bed. The position of the supporting grooved bars should be such that there is
room between the upper frame and the lower sliding one, for a woven wire mattress
and a woolen mattress on it. The sliding frame may be fitted at each end or at
the head only with a framework hinged to the horizontal frame so as to fold down
when the latter is pushed in.
The principle of the invention can be applied to a wooden bedstead.

I, MARY ANN CUNNINGHAM of 3 Clapton Square, London, Widow, 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:
This invention relates to improvements in bedsteads and has for its object the
construction of a bedstead which can be extended when a double bed is required
and closed when the extensible or additional bed is not in use.
So that this invention may be the more readily understood, drawings are appended
hereto.
Fig. 1. is a perspective view of an iron or brass bedstead with the extensible
attachment fixed ready for use. It will be seen that the bedstead proper is fitted
with two carrying rods C. connected to the frame by the castings D attached to
the legs. The extension consists of a frame with two legs, G. on the outside, and
two rollers B. acting upon the carrying rods C. This arrangement enables the
extension to be pushed under the bedstead proper when it is not in use.
Fig. 2. is a plan of the extensible frame A. with the rollers B. attached.
Fig. 3. is a plan of the permanent bedstead frame showing the position of the
carrying rods C. on which the rollers B. run.

page_text: The two legs of the extensible frame are detachable, the corner block H. being
provided with a tapped nut, as shown in dotted lines, the leg being provided with a
screw L. attached by any convenient means to connect with the tapped nut above
mentioned. This is shown in detail in Fig. 4.
Fig. 5. is a detail of the roller B. which works upon the axle K. and is kept in
position by an ordinary bolt.
The bedstead may be made either of metal or of wood as desired, or the exten-
sible frame may be of wood fitted with gun metal, or hard wood rollers, and may
be attached to an iron or brass bedstead.
The carrying rods C. may be of any convenient section and may be fitted with
V shaped grooves on the upper surface in which the extensible frame can slide, in
which case the extensible frame will be fitted with V shaped runners in place of
the rollers B. which V shaped runners will move backward and forward in the
grooves, as before mentioned, fitted into the upper surface of the carrying rods C.
The position of the carrying rods is so arranged that the extensible frame should
run freely underneath the permanent bedstead and leave room for a wire mattress
and a woollen or hair mattress thereon. The distance for this may be made as
found convenient.
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. An improved extensible bedstead substantially as described and illustrated in
the foregoing Specification and drawings.
2. The addition to an ordinary bedstead of the carrying rods C. together with
the extensible frame shewn in Figure 2.
