Improvements in Mattress Frames and Bedsteads.
We ISAAC CHORLTON of No. 17 Blackfriars Street, Manchester, in the County
of Lancaster, Spring Mattress Manufacturer, and WALTER OLDHAM, of the
same address, Manager, do hereby declare the nature of this invention to be as
follows:-
Our said invention relates to improvements in the manufacture of mattress
frames aud bedsteads.
According to our improvement we cast both sides and ends of the mattress frame
in one with the corner blocks or dovetails whereby the mattress frame is connected
to the uprights or bedstead ends. In doing so we make the mattress frame ends
higher than the sides so as to allow the woven wire mattress to extend above the
sides. The casting of the ends and sides together by means of the connecting
corner or dovetail blocks results in the production of a rigid parallelogramic
frame the ends being as already said at a greater altitude than the sides.
tails or other suitable connecting means on the cast corner blocks permit of the
ready attachment of the mattress frame to the bedstead ends or uprights.
Dove-
The sides and ends might consist of tubes or angle irons or combinations of
tubes and angles might be used in making the frame.

Our said invention relates to improvements in the manufacture of mattress
frames and bedsteads.
According to our improvements we cast both sides and ends of the mattress
frame in one with the corner blocks or dovetails, whereby the mattress frame is
connected to the uprights or bedstead ends. In doing so we make the mattress
frame ends higher than the sides so as to allow the woven wire mattress to extend
above the sides. The casting of the ends and sides altogether by means of the
connecting corner or dovetail blocks results in the production of a rigid parallelo-
gramic frame the ends being as already said at a greater altitude than the sides.
Dovetails or other suitable connecting means on the cast corner blocks permit of
the ready attachment of the mattress frame to the bedstead ends or uprights.

To render our invention fully understood we will now proceed more fully to
describe the same with reference to the annexed two sheets of drawings.
Fig. 1. (Sheet 1) is a perspective view of a complete bedstead, the mattress
frame being constructed in accordance with our invention. Fig. 2 is a similar view
with the mattress frame shown detached and raised up from the dovetails in the
corner blocks of the bedstead ends.
Fig. 3 (Sheet 2) is a side elevation of the two ends of the bedstead and mattress
frame, part of the fig. being removed for want of space.
Fig. 4 is a plan of the mattress frame ends.
According to our invention we cast the sides a and the ends bb' of the mattress
frame into one parallelogramic frame, the said sides and ends being connected and
cast together by the four corner blocks c.
The ends bare situated at a higher level than the sides, thus allowing the
elastic mattress surface d to extend over the sides a for the full width of the
bedstead. The elastic mattress is furnished at each end with bars e e¹ which rest
on the sides a of the mattress frame. The bar e is fixed, being bolted to the end b
with the
by bolts f. The other mattress bar el is connected by straining bolts g
end 6 and by turning these bolts the bar el can be drawn towards the end 61 and
the elastic mattress surface d strained to the required extent. A handle such as
the handle 4, indicated in Figs. 1 and 2, may be used to operate the straining
bolts g.
The four corner blocks c are made with dovetail projections c¹ which
engage with dovetail recesses in the blocks i cast on the bedstead ends. Thus to
put the bedstead together it is only necessary to drop the frame into the dovetails.
For transport the elastic mattress may be detached from the frame and rolled up
on its bars, but the mattress frame is always in a condition to be dropped into
position on the bedstead ends.
The relatively higher position of the ends of the mattress frame as compared
with the sides, is a feature in the construction of our improved mattress frame.
The bars e e¹ may be of wood or of double L or angle iron.
Although the ends and sides of the mattress frame are shown in the drawings to
consist of angle irons, they might be of tubing or we might use combinations of
tubes and angle irons.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is.
1. A mattress frame having its sides and ends cast together by the corner blocks
so as to form a rigid parallelogramic frame, the ends of the said frame being
at a higher level than the sides, for the purposes and substantially as described
and shown.
2. A mattress frame having its sides and ends cast together by the corner blocks,
the ends being above the level of the sides and fitted with an adjustable elastic
wire mattress extending the full width of the frame and above the sides,
substantially as described and shown.
