I, REINDERT GERRIT VOS VAN AVEZATHE, of Gordon Place, High Street,
Erdington, near Birmingham in the County of Warwick, bedstead manufacturer,
do hereby declare the nature of my invention for "IMPROVEMENTS IN THE MANU-
FACTURE OF METALLIC BEDSTEADS, COTS AND SIMILAR ARTICLES 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 of reference marked thereon:-
―
My invention relates to the mountings of the 'corners' on the pillars of bed-
steads, cots and similar articles, and is intended to supply an easy means of
applying to the commoner class of these goods mountings equal in appearance to
those which are now used only on bedsteads of the better quality-I will first
describe the method followed in the trade in regard to the better quality, when my
invention will be more easily understood.
In the accompanying drawings figures 1, 2, 3 and 4 illustrate the method just
referred to. Figure 1 is an elevation shewing the part of the pillar of a bedstead
on which the corner' is cast. Figure 2 is a plan of figure 1. Figure 3 is a section
on line A B of figure 2.
,
The corner on the pillar of a bedstead usually consists of a chilled casting C,
formed, on two adjacent sides, into dovetails D D at right angles to each other.
These dovetails receive the correspondingly shaped ends of the angle bars which
hold the head and foot of the bedstead rigidly in their upright position. It will be
seen from figure 4 (which is a plan of figure 1 with the mounting. E, immediately
to be referred to, removed) that the outline of the remaining part of the corner' is
a segment of a circle considerably larger in diameter than the pillar itself, which
is letter F. This part of the 'corner' is covered, for the purpose of ornamentation,
with a circular piece of sheet or cast brass G, (figures 3 and 4) which is held in
position by circular mountings E E made of sheet or cast brass. These mountings
are slipped on to the pillar from the bottom and top and brought in contact with
the corner' C, their rims passing over the circular piece G and securing it as shewn
in figure 3-The mountings E E are then fixed in their position by means of small
set screws H H (figure 1) which pass through the mountings and into the pillars.
་
It will now be obvious that the brass mountings described, and illustrated in
figures 1, 2 and 3 can only be used in connection with a pillar on which there is no

whose pillars and railwork are held together by chilled castings which would
obstruct the passage of the mountings along the pillar.
Figures 5, 6, 7, 8, 9 and 10 illustrate the device for overcoming the above
difficulty which constitutes my invention. Those details in these views which
correspond with details in figures 1, 2, 3 and 4 are distinguished by the same
letters of reference. Figure 5 is an elevation corresponding to figure 1, and
figure 6 is a plan of figure 5. Figure 7 is an elevation similar to figure 5, but does
not shew the mountings E E. Figure 8 is a plan of figure 7. Figures 9 and 10
are respectively an elevation and plan of the mounting E.
According to my invention the mounting E is made with a part (equal to about
one quarter, but varying with different sizes of pillar) cut away as shewn in
figures 5, 6, 9 and 10. Upon the pillar F, and on opposite sides of it, I chill, in
addition to the usual 'corner,' two lugs or projections K K (Figures 5, 6, 7 and 8)
the outer surfaces of which are at all points of a diameter slightly greater than the
inside diameter of the mounting E at the same points. When the mounting E is
to be placed on the pillar, it is held in such a manner that its two edges come in
contact with the pillar between the lugs or projections K K. A slight push or jerk
is then sufficient to spring the mounting on to the pillar. The mounting E is then
twisted round the pillar until it occupies the position shewn in figures 5 and 6,
when it rigidly grips the lugs or projections K K, owing to its own elasticity and
the difference of diameter explained above. I may mention that the part G, shewn
in figures 3 and 4, but omitted in the views illustrating my invention for the sake
of clearness, is, for the purpose of my invention, inade shorter 'than shewn in
figure 3, being only of sufficient length to come just inside the mounting E when
the latter is in position. When the mounting E is being forced round the pillar as
already described, it is caused to slightly overlap the part G, whose elasticity, being
exercised in the opposite direction to the elasticity of the mounting E, adds to the
firmness of the mounting while securing the part G round the outside of the chilled
casting C.
In order to give a solid and finished appearance to the mounting E, and to still
further increase the rigidity of the whole arrangement, I fill up the break in the
mounting E with a suitably shaped piece of iron, brass or other metal, which, when
in the position shewn by dotted lines in figure 10, forms the complement of the
mounting E. This complement is fixed to the pillar F by means of a small pin or
set screw similar to that shewn in figure 1.
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 general arrangement of mounting E and lugs or projections K K for fixing
the mountings of bedsteads, cots and similar articles on to the pillars and corners
without the necessity of passing such mountings along the pillars, substantially as
herein described and illustrated by the accompanying drawings.
