PROVISIONAL SPECIFICATION.
Improvements in Spring Mattress Frames for Shut-up Bedsteads,
and Cots, and the like.
GEORGE HENRY TOMPKINS, Teacher of Handicratts and Miner, 28, Newton Street,
Bensham Road, Gateshead-on-Tyne, do hereby declare the nature of this invention
to be as follows:-
It consists of sections of tubing telescoping into each other, & held together
at the extream ends, by cross bars. The cross bar at the foot of the frame is fixed
& immovable.
The cross bar at the head acts as a roller to wind the spring mattress on, &
on opening, or drawing the telescope out. The cross bar or roller is fitted at
each end with a ratch wheel to keep the mattress in tention. A small "click" is
fixed to the frame for the purpose of keeping the roller or cross bar from sliping.
Two tention bars are also fitted to keep the spring mattress slightly above the
frame a liner for strength at each joint & a pin to keep it open.

GEORGE HENRY TOMPKINS, Ramseys Buildings, Lintz Green Station, County
Durham, late of Newton Street, Gateshead-on-Tyne, County Durham, Teacher
of Handicrafts and Miner, do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
It consists of sections of tubeing telescoping into each other, and held together
at the extream ends by cross bars.
The
The cross bar at the head acts as a roller to wind the spring mattress on.
cross bar or roller is fitted with a ratch wheel at each end to keep the mattress
in tention.
A small "click" is fixed to the frame for the purpose of keeping the roller
or cross bar from slipping.
Two tention bars are fitted on the frame, (to keep the spring mattress slightly
above the frame), they are fitted to the frame by the cross bars passing through
an eyelet, and pulled into position by a hooked handle, the hook passing over
and resting on the frame.
Diagram X, Y, Sheet No. 2 shews the end view and plan of tention bar.
Diagram X, K, is the eyelet or bearing through which the cross bar passes

page_text: before fixing it to the frame, thus leaving the tention bar clear, and free to be
moved up or down.
L, Diagram X is the tention bar proper shewing where it is welded, and bent
to support the strain of the wire mattress.
M, Diagram X is a handle with a hook attached, and bent so as to keep the
hand clear of the frame when pulling the hook over the frame.
N, Diagram X is a joint to allow handle to be worked whilst fixing the tention
bar.
P, Diagram X is the hook by which the tention bar is held in position.
Diagram Y shews plan of the end of tention bar and handle.
L, Diagram Y is a section shewing where the tention bar is welded too.
The tention bars are composed of a piece of metal bent at each end into elbows,
and pierced at the end to allow the cross bar to pass through. Two pieces of
metal are welded on to the tention bars, one at each end and close to the eyelet ;
to which is fitted the handle which has a hook on one side and the hook is drawn
over the frame, thus secureing the tention bars, and keeping the wire mattress
above the frame.
The ratch and eyelet, Figs. H, J, are fixed to the roller and frame, thus:
The eyelet is incerted into the tube, and secured by a bolt passing through both;
on this bolt is hung a click which is bent so as to rest on the face of the ratch
wheel and thereby hold the ratch, and keep the cross bar from slipping. The
ratch is fixed on the end of the cross bar after it has passed through the eyelet,
and is a preventitive to the frame from coming off the cross bar.
A liner 2 inches in length is inserted in each end of the tubes for the purpose
of (1) faciliating the sliding of the tubes into each other and (2) strengthening
cach tube at the joint, (Fig. C).
The telescopic frames are held extended when in use, by a pin D in diagram;
which is inserted horizontly and transversly at each joint, the pin thus rests
against the end of the larger section of the tubeing, (Fig. 1).
The spring mattress is attached to the roller by small chains 1 foot in length,
fixed to the clamps E, F, in diagram, by small eyebolts, and to the roller by
hooks. There are four chains used; they are placed so as to distribute the strain
of the tention on the spring mattress equally on the cross bar thus allowing the
telescope frame to open and close quite freely Fig. (E, F).
The clamps are composed of two metal plates one being bent into the form of
a hook; the wire mattress is laid into the hook and then the other plate, which
is in the form of a wedge is pressed against the wire, in the hook of the other
plate and secured.
The eyelet or bearing is composed of a piece of round metal flattend at one
end as shown in diagrams H, J. Sheet 1, a hole is bored in the flattend end to
act as a bearing for the roller or cross bar, the round end is pierced to receive
a small bolt, on which the pawl or click is hung, R, Diagram V. The round end
of the eyelet H J Sheet 1, is incerted into the tube A, Sheet 1, and then the small
bolt S, Diagram V, on which the click is hung is incerted in the hole through
the tubeing A, Sheet 1, and the eyelet H, J, Sheet 1, and thus held in position.
H, Sheet 1 is an elevation shewing the eyelet and ratch in position. The
Diagram J, Sheet 1, shows plan of eyelet and ratch when in position on cross
bar.
Diagram V Sheet 3 is a view shewing H, J, Sheet 1, in position when fixed
to the tubeing, and also shows click R Diagram V, in position.
S, Diagram V shows the bolt on which is hung the click R, and which also
holds the eyelet H, J, Sheet 1, to the tubeing A, Sheet 1, and Sheet 3.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is;-
(1) The use of tubeing in constructing a telescoping frame, as shown at A, B, C,
in diagram.
