COMPLETE SPECIFICATION.
An Improved Joint or Connection, more especially designed for
Use in Metallic Bedsteads and the like.
I, WILLIAM PRICE of 6 Gerrard Street, Aston, Birmingham, Army Pensioner
and Time Keeper, 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 :—
My invention relates to an improved form of "catch" joint or connection and
is designed more especially for metallic bedsteads and the like. Heretofore the
joint for assembling the frame pieces and corner blocks or brackets for bedsteads
has been made by tongue and groove formed or cast on the said frame pieces and
blocks.
By my improved joint I am enabled to dispense with the usual cast frame pieces
and substitute frame pieces of rolled iron, etcol or metal of L shaped section each
end of said shaped frame pieces being suitably formed to constitute one part of my
improved catch joint, the corner blocks which are likewise suitably constructed to
receive the ends of said frame pieces forming the other portion of this improved
joint.
In order that my said invention may be clearly understood I have illustrated the
same in the accompanying sheet of drawings in which Fig. 1 shows a perspective
view illustrating one form of my invention, Fig. 2 is a similar view showing a
modification, Fig. 3 represents a perspective view, of the shaped bar, illustrating
the method of forming the catches or tongues on said bar, and Fig. 4 is a modified
form of the catch or tongue.
In carrying my said invention into practice I form at the extremities of bar A
of shaped section constituting the frame pieces of the bedsteads or the like a
tongue or catch a by cutting away the portions a' a' on the upper face a thereof
(shown in dotted lines Fig. 3) so as to leave a tongue a projecting. On the sido
face a of the said bar AI likewise cut away the portion a so that the extremity
of said face will lie somewhat behind the root of the projecting tongue a'. I
now continue to cut along the side face a for a distance -y for the purpose, of
enabling the part a³ of the side face a to be bent inwards at right angles to said
face, thereby forming a tongue or catch.
I then bend down the projection a at right angles to the face a of the
said shaped bar, thereby forming another tongue or catch, seo Fig. 1.
In the corner blocks or brackets B I form a recess corresponding in depth
and configuration to the shaped bar, so that the faces of this bar when the latter
engages with the corner block, will be flush with the faces of the said block.
In order to lock the bars forming the side frames and corner block in position,
1 provide in the upper face of said recess b a slot or recess adapted to receive
the tongue or catch a' and in the side face I form a slot or recess to receive the
tongue or catch a'.
To prevent too great a strain being thrown upon the said tongues and recesses
I provide the corner blocks B with a ledge & upon which the bottom edge a' of
the said frume A may abut.
It will be seen that the parts connected in the before described manner can be
easily assembled to form an extremely simple, rigid and durable joint and one that
can be easily and rapidly taken to pieces, but if it is desired to form a more
permanent joint in bedsteads such as in the case of hospital bedsteads, I prolong

page_text: the catch or tongue a Fig. 4 to a sufficient extent to pass through the corner
block or bracket, and project beyond the same aud secured it in its place by
means of a pin or like suitably attached to the blocks or frame and passed through
a hole a clamping the said tongue or catch and the block together.
In Fig. 2 I have shown a slight modification of my said invention which consists
in producing the tongue a on the side face of the L shaped bar beyond the
tongue a on the upper face of said bar the recesses in the corner blocks being
made to correspond in position.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what!
claim is-
(1.) In bedsteads or the like, a joint formed by catches a adapted to enter
recesses or slots respectively provided in the corner blocks or brackets,
substantially as described with reference to the accompanying drawings.
(2.) In bedsteads or the like, a joint formed by a block Band bar of shaped
section, in which the extremity of the upper face is cut away and turned down at
right angles to form a tongue or catch and in which the extremity of the side
face is shortened and turned inwards at right angles to the said face to form the
tongue or catch a', the said tongue or catches being adapted to engage with
corresponding recesses or slots in the block B, substantially as described with
reference to the accompanying drawings.
(3.) In bedsteads and the like, a block B having a recess or slot B' in its upper
face and a recess or slot in its side face in combination with the shaped bar,
the said recesses
or slots being adapted to receive tongue or catches on the
aforesaid bars substantially as described.
(4.) The method of forming a joint by providing tongues or catches on two
adjoining sides or faces of a bar, block or the like and recesses or slots in the
corresponding sides or faces of another bar block or the like adapted to receive
the said tongues or catches substantially as and for the purposes specified with
reference to the accompanying drawing.
(5.) The improved joint or connection substantially as described and with
reference to the accompanying drawing.
