PROVISIONAL SPECIFICATION.
Improvements in Wire Mattresses and the like.
ALFRED LAKIN, 71, Dearman Road, Birmingham, Manufacturers Manager, do
hereby declare the nature of this invention to be as follows:-
The object of my improvements in wire mattresses, is to make a true & simple
method, in the fittings, whereby, when the parts of the mattress come together,
they shall easily, & readily, & quickly be fitted by any unskilful person.
In carrying out my improvements in wire mattresses, I use any pattern frame,
with any design of wire mesh. I make in metal, a dovetail joint for sliding
purposes. Two of these are used. One part of the joint, being attached to both
sides of the frame, at one end, & the other corresponding halves being attached
to the one cross bar, of the frame. I make a long metal square or round or
V-shape or rectangular or any other shape groove or gutter & two of these, I let
into the sides of the frame at the end. Where it is intended, that the drawing
up of the mesh shall take place, I form a metal base plate, with a square, or
retangular ridge, whereon to work in the groove. This ridge, being bored, &
screwed for the recepton of the screwed pin, required in adjusting the mattress.
Operation. My improvements being in position, upon the frame, & two ends of
the sides of the frame, being provided with the ordinary L-shaped brackets; &
with the ordinary long tenson screw pin for rotating therein. I slide on cross
bar, of the frame (having attached to it one end of the mesh,) into position, by
means of the dovetail joint, next the ridges on the base plate attached to the
other cross bar are placed in the grooves, attached to the other end, of the frame.
thereby enabling the operator, to insert the two screwed pins into the screwed
holes, in the ridges of the base plate, with ease. The adjustment of the mattress
is then complete, by the rotating of the two long tension pins.
Considerable modification in detail, may be made without departing from the
spirit of my invention.-When carrying out my improvements in wire mattresses
& the various applications for the purpose set forth as the dovetail sliding boxes
or other sliding arrangements may be used & the different material also could be
employed.

I, ALFRED LAKIN, 71, Dearman Road, Birmingham, Manufacturers Manager,
do hereby declare the nature of this invention and in what manner the same is to
[Price 8d.]

page_text: be performed, to be particularly described and ascertained in and by the following
statement;-
The object of my improvements in wire mattresses is to make improved arrange-
ments in the fittings whereby the parts of the mattress shall easily and readily
be fitted by any unskilful person.
In carrying out my improvements I may use practically any pattern of frame
with any design of wire mesh. I make in metal a dovetail joint for sliding
purposes, one of which is used on each side at the one end, one part of the joint
being attached to the sides of the frame, and the other corresponding parts being
attached to the one cross bar of the frame. I make a long metal square or round
or shape or rectangular or any other shape groove or gutter and two of these
I let into the sides of the frame (one on each side) at the other end where it is
intended that the drawing up of the mesh shall take place, I form a metal base
plate with a square or rectangular ridge whereon to work in the groove; this ridge
being bored and screwed for the reception of the screwed pin required in adjusting
the mattress.
In order to more clearly explain this my invention I have appended hereunto
an illustrative drawing upon which are figures and numbers of reference, similar
numbers referring throughout the several views to the same thing or part, and in
which:-
Fig. 1, is a side view of a mattress frame made according to this my invention.
Fig. 2, is a plan view of the same frame.
Fig. 3, is an enlarged end view, and Fig. 4, a similar side view of the sliding
fitting at the one (rigid) end of the frame.
Fig. 5, is an enlarged side view, in part section, and Fig. 6, an end view of the
adjustable fitting, at the other end of the frame, while Fig. 7, is a cross sectional
view on line A-B of Fig. 5.
10, 10, 11, 11 constitute the mattress frame 10, 10 being the frame sides,
and 11, 11, being the rigid cross bar, and the adjusting cross bars respectively.
12 and 13, form a metal joint in which the parts 12, has a dovetail slideway
groove 14, to receive the sliding dovetail 15. The part 12, is firmly secured to the
sides 10, 10", by screws 16, or other suitable means, while the slide part 13, is
similarly secured to each end of the cross bar 11.
Again. At the other end of each of the sides 10, 10", I make the metal gutter 17,
which is let into the said sides. Upon each end of the cross bar 11ª, is secured
the adjustable screw nut fitting 18, whose upper part is made suitable for fasten-
ment to the bar 11", and its lower part 18", to loosely slide in the gutter 17, and
in which is formed a screwthreaded hole through which the adjusting pin 19
works. 20, is a resistance bracket plate, secured to the ends of sides 10, 10º,
through and against which the pins 19 work.
In the drawings I have not shown the wire mattress, except to indicate its
position at 21, in Figs. 1, 3, 4 and 5.
Its operation will now be readily understood to be as follows:-
The ends of the wire mattress are secured to the cross bars 11, 11", after the
usual manner. The cross bar 11, is then fitted to the sides 10, 10", by means of
the dovetails 15, being slid into the slideways 14. The other cross bar 11°, is
now placed in position, with its screw nut fitting parts 18", lying in the gutter 17,
and the pins 19, are connected up in the manner shown, when the mattress may
now be tensioned up as required by means of the pins 19.
It will be seen that modifications may be made in the details as to shape and
position of slides, slideways, &c., without departure from the nature of my
invention.
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

page_text: sides 10, 10%, by means of dovetail fittings 12 and 13, substantially as set forth
and shown.
2. In wire mattress frames, the combination with the cross bar 11ª, of the
fitting 18, with downwardly projecting part 18ª, slideway gutters 17, screw pins 19,
and bracket plates 20, carried on sides 10, 10", all substantially as set forth and
shown.
3. In wire mattress frames, the general combination and arrangement of parts
constituting these my improved means for construction of frame and tensioning of
same substantially as set forth and shown.
