We, SAMUEL ILSLEY WHITFIELD, of Watery Lane, Managing Director for
S. B. Whitfield & Co., Ld., Metallic Bedstead Manufactures, and GEORGE GALE
AND SONS, LD., of Upper Dean Street, Wire Mattress Manufacturers, both of
Birmingham, in the County of Warwick, do hereby declare the nature of this
invention to be as follows:-
Our invention which is a further improvement on Patent No. 25838 A.1). 1896
has for its object improvements in metallic bedsteads and refers to the dovetail
junction between the sides and legs of bedsteads for use in hospitals and other
such purposes where it is of the greatest importance that there shall not be any
interstice or angle where particles of dust can collect. In the case of junctions
made in accordance with the aforementioned specification where the dovetail
joint is seen on the top of the junction there is a tendency for small portions of
the chill around the dovetail to chip and fly off the result of the strain when in
use thus leaving interstises on the top in which dust accumulates and which are
most difficult to clear out.
By our invention we obviate any possibility of such chipping occuring on the
top and at the same time form a perfectly straight joint across the junction thus
reducing the possibility of any dust accumulating at this joint.
In carrying our invention into effect we form both parts of our junction either
round or elliptical in cross section and circular in longitudinal section where
connected to the legs while the end in which the side tube is chilled is rounded
off on the circle connected with the tube in combination with which we form our
dovetail projection upon that portion of the chill which is attached to the leg
the said projection only extending partially up the chill while the dovetail recess
is formed on the chill end of the tubular side but does not extend the whole
height of the chill a portion of which is left to cover the dovetail connection by
which means only a straight joint is exposed at the top of the junction which
joint can thus be made to form a much closer fit than where the dovetail forms
part of the exposed joint.

page_text: LIMITED, of Upper Dean Street, Birmingham, in the County of Warwick, Wire
Mattress Manufacturers, do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
Our invention which is a further improvement on Patent No. 25838 1896
has for its object improvements in metallic bedsteads and refers to the dovetail
junction between the sides and legs of bedsteads for use in hospitals and other
such purposes where it is of the greatest importance that there shall not be any
interstice or angle where particles of dust can collect. In the case of junctions
made in accordance with the aforementioned specification where the dovetail
joint is seen on the top of the junction there is a tendency when in use for small
portions of the chill around the dovetail to chip and fly off the result of the com-
pressional strain at the top of the joint thus leaving interstices at that point in
which dust accumulates and which are most difficult to clear out.
By our invention we obviate any possibility of such chipping occurring on
the top and at the same time form a perfectly straight joint across the junction
thus reducing the possibility of any dust accumulating at this joint.
In order that our invention may be clearly understood and more easily carried
into practice we have appended hereunto a double sized sheet of drawings upon
which we have fully illustrated the nature of our said improvements.
Figure 1 is a view looking down of the junction between the side and leg.
Figure 2 is a similar view of the junction to Figure I but looking up.
Figure 3 is a longitudinal section through the junction shewing the dovetail
in elevation.
Figure 4 is an elevation of the dovetail end of the leg part of the junction
when disconnected.
Figure 5 is an elevation of the dovetail end of the side part of the junction
when disconnected.
In carrying our invention into effect we form both parts A & B, of our junc-
tion either round or elliptical in cross section and circular in longitudinal section
where connected to the legs C at 6 while the end a¹ in which the side tube E
is chilled is rounded off on the circle at a where connected with the tube, in
combination with which we form our dovetail projection upon that portion B
of the chill which is attached to the leg the said projection only extending par-
tially up the chill while the dovetail recess is formed in the chill end A of
the tubular side E but does not extend the whole height of the chill a portion
of the metal being left at a³ to cover the dovetail connection by which means
only a straight joint K is exposed at the top of the junction which joint can
thus be made to form a much closer fit than where the dovetail forms part of
the exposed joint and which is free from liability to become chipped.
The shape of the dovetail 62 and recess a² may be varied without departing
from our invention.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that we
claim is:
In metallic bedsteads the junction A B rounded in section both vertically and
horizontally in combination with the connecting parts a², be arranged so as to
leave a straight joint at K substantially as and for the purpose herein set forth
and illustrated.
