Ships' Berths.
We ISAAC CHORLTON of Blackfriars Street, Manchester in the County of Lan-
caster, Spring Mattress Manufacturer, and GEORGE LAMB SCOTT of Manchester
aforesaid, Engineer, do hereby declare the nature of this Invention to be as follows:-
Our said Invention has reference to frames which are employed to support elastic
mattresses composed of woven wire or of combinations of woven wire and springs or
of chain and springs or of other suitable material as is well understood. The mode of
construction forming the present invention relates more especially to such frames as
are composed of angle iron or steel, and our objects are to produce a mattress frame
which will be easily taken asunder and put together and which will when put together
be rigid and firm. The ends of the side members or angle irons of the frame engage
with corner castings which are so formed as to correspond with and receive the said
angle ends for example the castings are formed at their lower parts with an angular
backing or bracket which fits the interior of the angle iron, a space being left between
a horizontal flange or partition in the corner casting and the top of the said angular
backing or bracket. The upper horizontal flange of the angle iron end thus enters a
recess in the corner casting and butts against the closed end thereof so that the interior
of the angle iron is supported on both faces and has its upper flange held in the recess
formned by the backing bracket and aforesaid horizontal partition. The ends of the
angle iron sides are thus supported and boxed in on all sides except on the outside of
the vertical flange, so that when secured by rivets screws or bolts to the said backing
bracket and horizontal partition the angle end is securely and firmly held. The upper
parts of the corner castings are formed with dovetail slots or recesses and corresponding
dovetail pieces being secured to the end bars of the mattress, the said end bars are
thus easily and quickly applied to the corner castings. A complete rectangular
mattress frame is thus formed to or upon which a mattress fabric may be attached or
strained in the usual manner. Instead of dovetailing the end bars to the corner
castings as described they might be secured by bolts or by other means this method of
construction being particularly applicable in making mattress frames for ships berths.

page_text: When it is desired to provide for the straining of the mattress surface upon the frame
by means of adjusting bolts or screws, we make the corner brackets at one end suited
to receive the said adjusting bolts or screws and the brackets to which the end bar of
the mattress is dovetailed or otherwise secured are made to clip and slide upon the side
angle iron members of the frame, a recess or slot being formed in the lower part of
each of the said sliding brackets which recesses or slots receive the horizontal flange
of the side angle members. The bolts or screws from the fixed end castings engage
with the said sliding brackets or with nuts held therein so that by turning the said
bolts or screws, the sliding brackets and attached end mattress bar, are drawn toward
the end of the frame and the mattress surface is correspondingly stretched. In
securing the end bars of the mattress to the corner brackets or to the sliding adjust-
able brackets we might in addition to the methods referred to secure the said end bars
detachably by the tongue and recess arrangement described in the specification of
Letters Patent No. 9718 granted to us on the 17th of August 1885. The construction
and arrangement hereinbefore described are applicable not only to bed and mattress
frames having angle iron sides but also to frames having side members of metallic
tubing or of wood.

Ships' Berths.
We ISAAC CHORLTON of Blackfriars Street, Manchester, in the County of Lancaster,
Spring Mattress Manufacturer, and GEORGE LAMB SCOTT of Manchester aforesaid,
Engineer, 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 and accompanying drawings:-
Our said Invention has reference to frames which are employed to support elastic
mattresses composed of woven wire or of combinations of woven wire and springs or
of chain and springs or of other suitable material as is well understood. The mode
of construction forming the present invention relates more especially to such frames
as are composed of angle iron or steel or of tubing and our objects are to produce a
mattress frame which will be easily taken asunder and put together and which will
when put together be rigid and firm.
And in order that our said invention may be properly understood we will now
proceed more particularly to describe the same with reference to the annexed two
sheets of drawings:-
On sheet 1 of the drawings Fig. 1 is a side view of a mattress frame constructed
in accordance with our invention.
Fig. 2 is a plan of Fig. 1.
Fig. 3 is an enlarged detail view of the corner bracket which unites the side and
end members.
Fig. 4 is a view of the said bracket at right angles to Fig. 1.
The side members a and the end members b of the frame are of angle iron or steel
and are connected at the four corners by the brackets c. These brackets are so formed
as to have beds or recesses into which the angle irons fit as more clearly shown at
Figs. 3 and 4. At the foot of the bracket c and beneath the horizontal flange or
partition d is a projection or backing against which the inner side of the angle
iron a hears. The upper horizontal flange of the angle iron enters the recess existing
between the flange d and the projection the end of the angle iron abutting against
the closed end of the bracket e and lying flush therewith, so that the whole side of the
corner bracket presents an unbroken surface which is conducive to neatness of appear-
ance. The ends of the angle iron sides a are thus supported and boxed in on all sides
except on the outside, which as has been said is flush with the surface of the bracket c.
Rivets eare used to secure the angle iron a to the backing d. Each of the ends ₺ of
the frame is similarly secured to the bracket c by rivets the bracket being recessed
at the back so as to allow the angle iron to lie flush with the end of the bracket and
thus present the same appearance of neatness which we effect at the junction of the
side inembers. It will be observed that the corner brackets are so formed as to raise
the end members b above the level of the side members a, so that the elastic metallic
or other mattress which is stretched between the end members and which is
represented in Figs. 1. 2. and 4 by the dotted lines g is carried above and clear of the
side members, thus allowing the full width of the frame to be utilised as mattress
surface. The height of the mattress surface g from the side members a can of course
be increased or diminished by correspondingly increasing or diminishing the height of
the upper part of the bracket c. The rectangular mattress frame constructed in this
manner may be laid upon a bedstead or used as a ships berth or the said corner
brackets might be furnished or formed with dovetail projections or recesses for

page_text: attachment to corner posts or uprights, or otherwise the side and end members instead of
being attached to a common corner bracket e as described might be attached in the
described manner to separate brackets which would be so formed as to be capable of
attachment by dovetails or bolts or other means either to each other or to a corner
bracket carried by the post or upright. Sheet 2 of the drawings illustrates the
construction of a mattress frame in which provision is made for straining the mattress
surface upon the frame by means of adjusting bolts or screws.
Fig. 5 is a side elevation of such a frame.
Fig. 6 is a plan of Fig. 5.
Figs. 7. 8. 9 and 10 are enlarged detail views of the brackets at the adjusting end
of the mattress.
The fixed corner brackets c at the end marked A in Figs. 5 and 6 are identical
with those illustrated on sheet of the drawings. At the end marked B we apply
brackets one of which is shown separately at Fig. 7 and in position on the side
member a in Fig. 10. As seen from these views the bracket his formed with a recess
which receives and boxes in the end of the side member a, and an upward projection /
has a hole through which an adjusting screw passes. The sliding brackets k one of
which is shown separately at Fig. 8 and which carry the adjustable end member are
formed to clip and slide upon the horizontal flange of the side members a the said
horizontal flange entering the recess seen in Fig. 8. The end angle iron b¹ is
attached by rivets or suitable means to the brackets and a hole is made through both
angle iron and bracket to admit of the passage of the adjusting screw i, which engages
with a nut m which fits into a recess in the bracket and is thereby prevented from
turning when the screw is manipulated. The mattress g is attached to the fixed end
bar band to the adjustable end bar band by turning the screws and so adjusting the
bar the mattress g can be strained to any desired degree. Instead of having nuts m
the holes through the brackets & might be threaded to fit the screws i. In securing
the end bars of the mattress to the corner brackets or to the sliding adjustable brackets
we might instead of or in addition to the methods described, secure the said end bars
detachably by the iongue and recess arrangement described in the specification of
Letters Patent No. 9748, dated 17th August 1885. The general construction and
arrangement of bed and mattress frames and ships berths hereinbefore described are
partly applicable to frames having side members of metallic tubing or of wood.
Having now particularly described and ascertained the nature of the said invention.
and in what manner the same is to be performed we declare that what we claim is :-
(1) The improved construction of mattress frames and ships berths wherein the
angle iron or steel side and end members of the frame are united by corner brackets e
formed with recesses to receive and partly to enclose the ends of the angle iron
members the said angle iron members lying flush with the surface of the brackets
substantially as and for the purposes hereinbefore described and shown.
(2) In the construction of bed and mattress frames and ships berths, the employ-
ment of corner brackets c formed and applied substantially as described and shown on
sheet 1 of the drawings.
(3) The arrangement and construction of mattress frames and ships berths having
an end har adjustable by means of screws and carried on brackets & which clip and
slide on the angle iron side members, in conjunction with the fixed end brackets h,
arranged, formed and acting substantially as described and shown on -heet 2 of the
drawings.
