I THOMAS KENDRICK of Summer Lane Birmingham in the County of Warwick
Manufacturer 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, reference being had to the accompanying drawings and to the
letters and figures marked thereon:-
This invention is applicable to metallic bedsteads of ordinary construction, whether
those known as fast end bedsteads or otherwise and consists in a method of attaching
cast bed bottoms mattresses or frames by means of a connection so constructed as to
compensate for any variation in gauge or irregularity of contraction in order to ensure
accuracy of fitting and avoid liability to breakage.
This effect by casting upon the head and foot pillars on one or both sides of the
bedstead corner blocks of a special construction, not having the ordinary dovetail and
introducing between those corner blocks and the dovetail or meeting surfaces of the
angle iron tube or bar sides of the bed hottom or frame intermediate blocks con-
structed to take their bearing against the corner blocks and to be capable of sliding
in a horizontal direction.
These intermediate sliding blocks may be made with dovetails upon their reverse
sides into which the bed bottoms or frames may be fitted or they inay be dispensed
with or they may be dispensed with in a separate form and be so constructed as to
form a permanent corner to the bed bottom or frame, having a meeting surface with
the corner block cast on the vertical pillars.
I will now describe the construction of these blocks by the aid of the accompanying
drawings.
Fig. 1. represents a portion of a pillar in elevation with the corner block (a) cast
upon it having a plain meeting surface (b) and a projecting portion (c) and having
also a screw pin (d) cast in.
Fig. 2 is a view of the intermediate sliding block (x) to fit up against the corner
block (a) having a recess (e) to receive the projection (c) and an elongated or elliptical
hole () through which the screw pin (d) passes holding the parts together as shewn
in Fig. 3.
The hole or perforation (✓) and the recess (e) are made in an elongated form to

page_text: allow the parts to slide horizontally in either direction from their usual positions as
shewn in Fig. 3 at (g) and thus adjust themselves to any variation in the gauge or
distance between the corners of the bed bottoms. (h) is the dovetail by means of
which the block is attached to the bed bottom or frame. This dovetail however may
be dispensed with and the flat meeting surfaces adopted as described below.
Figs. 4 & 5 shew a modification of my Invention in which the dovetails are dispensed
with and the block (a) is cast onto the angle iron tube or other side of the bed bottom
or frame. The flat meeting surface (b) is made to project so as to correspond with
the receding surface of the block (a) which takes its bearing thereon and is constructed
with two lugs or ears (f) with elongated or elliptical perforations to receive the screw
pins (d) and admit of the lateral action hereinbefore described.
Fig. 6. is a side elevation shewing another modification of the principle of my
invention (a) is the corner block cast onto the pillar and provided with a lip to receive
a projection or ridge (k) for the purpose of regulating the movement of the inter-
mediate block (a). A lug with an elliptical perforation through which the screw pin
cast in the corner block passes and is secured by a nut (d) is shewn at the bottom of
the block () which may be cast on the side (y) or fitted with a dovetail as required.
Figs. 7 & 8 shew a further modification and apply to bedsteads having corner blocks
and dovetails of the ordinary construction.
In this case (y) is the angle iron or tube side upon which is cast the block
having a lug (1) with an elongated hole as described above. The intermediate block (c)
is also fitted with a lug into which a screw pin is cast passing through the hole in the
lug () and secured by a nut (n). The meeting surfaces of the blocks (a and a) may
be constructed as shewn in Fig. 7 and the intermediate block (a) is provided with a
dovetail to fit into the ordinary corner block as shown in Fig. 8. The lugs may also
be cast upon either or both sides or upon the upper part of the blocks (a and x).
. I do not confine myself to the particular forms shewn, the construction of the
meeting surfaces nor the number or position of the lugs as these may be greatly varied,
my object being the formation of meeting surfaces capable of a lateral sliding action
at the same time being held together by a screw pin and nut.
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 :
The construction of a compensating corner block for cast bed bottoms or mattress
frames substantially as herein set forth and specified.
