We ISAAC CHORLTON of Blackfriars Street, Manchester in the County of Lancaster
Spring mattress manufacturer and GEORGE LAMB SCOTT also of Manchester aforesaid,
Engineer, do hereby declare the nature of this invention to be as follows:-
Our Invention relates to the metallic frames of mattresses and particularly to the
cases wherein the said frames are composed of tubular side members attached to end
cross bars the object of our invention being to simplify the construction and at the
same time to obtain facility of connection of the parts. In a frame constructed in
accordance with our invention a socket block is firmly riveted, brazed, or secured at
or near each end of an angle iron cross bar and two of such cross bars are connected
together to form the frame the connecting members being metal tubes. The socket in
each of the said socket blocks is prepared to receive a tube end and is formed with
slots or recesses to receive the ends of a cross pin which is fixed near the tube end.
When the tube ends are passed into the sockets the said pins by entering the recesses
in the socket blocks lock the tubes in position so that they cannot turn in the sockets.
To still further secure the tubes in the sockets screws, bolts, wedges, or other suitable
means may be employed. In practice we form each socket block to receive a set
screw which when tightened up bears against the tube and holds it securely in position.
The parts of the frame can be very quickly put together and when taken apart can be
packed into a small compass.

page_text: Improvements in Mattress Frames.
We ISAAC CHORLTON of Blackfriars Street, Manchester, in the County of Lancaster
Spring Mattress Manufacturer, and GEORGE LAMB SCOTT also 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 Invention relates to the metallic frames of mattresses and particularly to the
cases wherein the said frames are composed of tubular side members attached to end
cross bars the object of our invention being to simplify the construction and at the
same time to obtain facility of connection of the parts. In a frame constructed in
accordance with our invention a socket block is firmly riveted, brazed, or secured at
or near each end of an angle iron cross bar and two of such cross bars are connected
together to form the frame the connecting members being metal tubes. The socket in
each of the said socket blocks is prepared to receive a tube end and is formed with
slots or recesses to receive the ends of a cross pin which is fixed near the tube end.
The parts of the frame can be very quickly put together and when taken apart can be
packed into a small compass.
And in order that our said invention may be properly understood we will now
proceed more particularly to describe the same reference being had to the annexed
sheet of drawings and to the letters and figures marked thereon, to be as follows:
Fig. 1 is a side elevation of one corner of a mattress frame the members of which
are supposed to be united by our improved means.
Fig. 2 is a view at right angles to fig. 1, and Fig. 3 is a plan.
The corner casting or socket block a which is made hollow for the sake of lightness
as indicated by the dotted lines, is secured to the angle iron end 6 either by means of
rivets c as shown in the drawing or by any other suitable means.
In the block a we
core or otherwise form a socket which is open at the front X and closed at the back.
The collar or projection d at the front of the socket is formed with slots e and the
tubular side of the mattress which fits the socket carries a transverse pin g projecting
beyond the tube on each side, so that when the tube fis thrust into the socket the
projecting ends of the pin g enter the slots e in the collar d and prevent the tubular
side from turning in the socket. To prevent the tube from being readily withdrawn
from the socket, we apply a set screw h which is screwed through the inner side of
the block so as to bind the tube in the socket. For convenience the set screw h may
have a wing head as shown or a 'square or slit head may be used. The set screw
may be applied in any other convenient situation for example at the outer side of the
block as shown at i Fig. 1 or instead of a set screw the tube might be secured by a
wedge or tapered cottar or by a pin driven through both block and tube, in which latter
case the slots e and pin g hereinbefore described might be dispensed with. It is. to be
understood that a block a is provided at each corner of the rectangular mattress frame
the angle irons b having such a block at each end. When the ends of the tubular

page_text: sides fare inserted in their respective sockets a complete mattress frame is formed, the
metallic wire or other mattress surface being stretched and secured by the hooks k to
the angle ends b. Another mode of preventing the tube from turning in its socket is
shown at Fig. 4. In this instance a circular plug / having a squared end m is inserted
into the end of the tube and secured by pins as shown. The recess in the block a
is cored to fit the squared end m so that the tube cannot turn. The transverse ping and
slots e can therefore be dispensed with. Such a mode of attachment as that shown at
Fig. 4 could be used in the case of a side member which is not tubular in section. We
prefer however to use the arrangement shown at Figs. 1. 2. and 3.
The hereinbefore described simple and secure methods of uniting the members of a
mattress frame enable such frames to be easily connected and disconnected, while the
parts when separated occupy little space and are easily packed for transport.
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 :-
In the manufacture of mattress frames uniting the side and end members by means of
a recessed or socket block attached to the angle iron ends and so formed as to receive
the round or otherwise suitably formed ends of the tubular or other side members of
the frame, the said side members being locked or prevented from turning in the said
sockets by the indicated means substantially as herein before described and shown.
