Complete Specification Accepted, 14th Dec., 1888
I, HENRY HERMAN CHILTON, of 35 Merridale Road, Wolverhampton in the County
of Stafford, Tin and Iron Plate Worker and Japanner, do hereby declare the nature
of this invention to be as follows:-
Although it is my intention to use this invention mainly in connection with the
improvements in wire wove spring mattresses for which a patent numbered 829 was
granted to me in 1887, it is applicable also to all kinds of wire wove spring
mattresses. I will describe my invention in its relation to the system of mounting
wire wove spring mattresses as set forth in my Specification No. 829 of 1887, when
its application to wire wove spring mattresses mounted in any way whatsoever will
be obvious.
According to my invention, I hang the wire wove webbing mounted in accordance
with any of the modifications described in the aforesaid Specification, on to the modified
bedstead described below, by. means. of a modification of the clip used for the same
purpose in my former invention, and also described in the above mentioned
specification.
In the construction of the bedstead I entirely dispense with the end angle iron at
present used to give rigidity to the head and foot of a metallic bedstead, their function
being fulfilled in my invention by the tubes with which the webbing of the mattress
is mounted, as will shortly be obvious. The side angle irons I fit into their position,
as usual, by means of dovetails cast on each end of each angle iron, the dovetails
fitting into corresponding dovetails cast upon the pillars of the bedstead. On the top
of each dovetail on the angle irons, and preferably at the same operation as that of
casting the dovetail itself, I cast a body of metal, roughly speaking, cubic in shape,
and projecting above the angle iron to a distance about equal to its width. And
in this body of metal I cast a pin, in such a way, that it projects longitudinally
outwards and away from the angle iron. As there are two angle irons, and each is
furnished with two dovetails, each of which bears one pin, there are four of these
pins altogether, all in the same plane and all projecting outwards longitudinally:
and two project outwards longitudinally towards the head, and two towards the foot
of the bedstead.
Referring now to the mattress, I fix on each of the tubes with which it is mounted,
two clips like those described in my specification No. 829 of 1887. These clips are

page_text: modified to the extent of having perfectly plain holes drilled through their lower
extremity, these holes being of the same size as the pins above described, and
extending in the longitudinal direction of the mattress. The two clips on each tube
of the mattress are so placed that the distance between the axes of the holes in the
clips, and between the axes of the aforesaid pins, are equal, the relation of the
xes to each other being the same in both cases. The method of hanging the
mattress in position will now be evident. After the clips at one end of the mattress
have been fitted on to the two pins at the head or foot of the bedstead, the other end
of the mattress is pulled till its clips can be fitted on to the pins at the foot or head
(as the case may be) of the bedstead-The tension of the mattress then holds the
clips firmly on the pins, and the mattress remains tightly stretched. The great rigidity
arising from the relative position of the side angle irons of the bedstead, and the tubes
of the mattress, and the firmness imparted to the whole arrangement by the elasticity
of the .mattress, enable me to altogether dispense with the end angle irons of the
bedstead.
Although I have described my invention in connection with my former Specifi-
cation it will be manifest that it is applicable, with very slight modifications of the
clips employed, to wire wove spring mattresses mounted in any way whatsoever.

page_text: COMPLETE SPECIFICATION.
A Combined Metallic Bedstead and Wire-wove Spring Mattress.
1, HENRY HERMAN CHILTON, of 35 Merridale Road, Wolverhampton in the County
of Stafford, Tin plate worker and japanner, 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:
-
Although I use my invention mainly in connection with the improvements in wire-
wove spring mattresses for which a patent numbered 829 was granted to me in 1887,
it is applicable also to other kinds of wire-wove spring mattresses.
I will describe my invention in its relation to the system of mounting wire-wove
spring mattresses, as set forth in my specification No. 829 of 1887, when its
application to wire-wove spring mattresses mounted in other ways will be obvious.
According to my invention I hang the wire-wove webbing mounted in accordance
with any of the modifications described in the aforesaid specification, on to the modified
bedstead described below, by means of a modification of the clip used for the same
purpose in my former invention and also described in the aforesaid specification.
According to my invention, the side angle irons of a bedstead are fitted into
their position, as usual, by means of dovetails cast on each end of each angle iron,
the 'dovetails fitting into corresponding dovetails cast upon the pillars of the bedstead.
Near to each dovetail on the angle irons, and preferably at the same operation as
that of casting the dovetail itself, I cast a body of metal, roughly speaking, rectangular
in shape, and projecting above the angle iron to a distance about equal to its width;
and in this body of metal, near the top, I cast a pin in such a way that it projects
longitudinally outwards and away from the angle iron. As there are two side angle
irons, and each is furnished with two dovetails, each of which bears one pin, there
are four of these pins altogether, all in the same plane and all projecting outwards
longitudinally and two project outwards longitudinally towards the head, and two
towards the foot of the Bedstead.
Referring now to the mattress, I fix on each of the tubes with which it is mounted,
two clips like those described in my specification No. 829 of 1887. These clips are
modified to the extent of having perfectly plain (instead of screwed) holes drilled
through their lower extremities, these holes being of the same size as the pins above
described, and extending in the longitudinal direction of the mattress. The two clips
on each tube of the mattress, are so placed, that the distance between the axes of
the holes in the clips, and the distance between the axes of the aforesaid pins, are
equal, the relation of the axes to each other being the same in both cases.
method of hanging the mattress will now be evident. After the clips at one end of
the mattress have been fitted on to the two pins at the head or foot of the bedstead,
the other end of the mattress is pulled till its clips can be fitted on to the pins at the
The

page_text: foot or head (as the case may be) of the bedstead. The tension of the inattress then
holds the clips firmly on the pins, and the mattress remains tightly stretched. The
great rigidity arising from the relative position of the side angle irons of the bed-
stead and the tubes of the mattress, and the firmness imparted to the whole arrange-
ment by the elasticity of the mattress, enable me to altogether dispense with the
end angle irons of the bedstead, whenever I wish to, although in practise I prefer
to use them; but instead of furnishing them at each end with dovetails to fit into
corresponding dovetails on the pillars of the bedstead, as is usually done, I find it
handier to cast them into the roughly rectangular mass already described, on the
side angle irons. The side and end angle irons then form a rigid rectangular frame-
work bearing the wire-wove spring mattress, and this framework can be lifted bodily
away from the pillars of the bedstead, or hung thereupon, as desired.
Having thus stated the nature of iny invention, I will now proceed to describe it
more particularly, reference being had to the accompanying drawings and to the
letters of reference marked thereon.
The same letters of reference occurring on the two figures indicate corresponding
parts.
Figure I is a side elevation of the salient parts in my arrangement of combined
bedstead and wire-wove spring mattress, and figure 2 is an elevation of either of the
ends of figure I. In figure I, A. A. is one of the side angle irons of a bedstead, having
cast upon it near each end, the rectangular masses of metal B. B. (see also figure II).
Upon the rectangular masses B. B, and projecting longitudinally outwards from them,
are the dovetails C. C (figures I and II) which fit into corresponding dovetails on the
pillars of the bedstead when this is being erected. Near the top of the rectangular
masses B. B, and projecting longitudinally outwards therefrom, are the pins D. D,
shewn in figure I by dotted lines. E E are the clips as described in my specification
No. 829 of 1887, but the holes in their lower parts are perfectly plain instead of
being screwed, and are of the same diameter as the pins D. D. The clips E. E.
grip the split tubes F. F, which in their turn firmly hold the wire webbing G. G. in
accordance with my patent No. 829 of 1887. H-(figure II) is one end angle iron
of the bedstead cast rigidly into B. B.
It will be obvious on an examination of the drawings, that the side angle irons A A.
and the end angle irons H H, are fixed. by the rectangular masses B. B. into a rigid
rectangular framework, which, by means of the dovetails C. C; can be hung on to
the corresponding dovetails on the pillars of a bedstead, or taken therefrom, at will.
The method of fixing the spring mattress mounted according to a modification of
my patent No. 829 of 1887, on to this framework will now be easily understood.
The clips E. E. on the tube F at one end of the wire-wove webbing, are fitted on to
the pins D D. at one end of the framework. The other clips E E are then drawn
over the rectangular masses B. B. at the other end of the framework, and spring
on to the pins D. D. at that end.
The combined mattress and framework is then complete and can be fixed by means
of the dovetails C. C. into the corresponding dovetails on the pillars of the bedstead,
or taken therefrom, at will.
Of course it is necessary to have the webbing G sufficiently short to draw the
clips E. E. together with considerable force, as it is upon this that the security of
the wire webbing depends. When the latter is in position, as shewn in the
drawings, the tension must be sufficient to enable the webbing to answer all the
purposes for which it is intended.
Although in practise I now find it preferable to use end angle irons H H, they
may be dispensed with if desired.
Again, although I have described my invention in connection with my former
specification No. 829 of 1887, it will be manifest to any practical person that wire-
wove webbing mounted in many ways other than that set forth in the said specification,
could be hung on the framework herein described either by means of a modification
of clip E. E, or otherwise.

page_text: Having thus stated the nature of my said invention, I declare that what I
claim is :
I. The rigid framework consisting of side angle irons A. A. and end angle
irons H. H, held together by masses of metal B. B, rectangular or otherwise in
shape, substantially as and for the purpose herein described and illustrated by the
accompanying drawings.
II. The masses of metal B. B, rectangular or otherwise in shape, bearing the
pins D. D substantially as and for the purpose herein described and illustrated by the
accompanying drawings.
III. The modification of clip E E. substantially as and for the purpose herein
described and illustrated by the accompanying drawings.
IV. The general arrangement of framework and spring mattress, forming together
a combined bedstead and wire-wove spring mattress, substantially as and for the
purpose herein described and illustrated by the accompanying drawings.
Dated this 7th day of November 1888.
