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:-
My invention has for its object to supersede the usual method of mounting wire
wove spring mattresses, which is as follows. After a suitable length of wire webbing
out of which the mattress is to be made, has been cut off, each end of it is tightly
fixed between two stout strips of wood, which are held together by screws. Suitable
ears of wrought or cast iron are then screwed on to the wood strips, and by these cars
the mattress is hung upon the framework of the bedstead. According to my invention
the aforesaid strips of wood are dispensed with. In their place, I use a wrought iron
tube, having a longitudinal split extending along the whole of its length, of sufficient
width to admit of the insertion of the wire webbing. When the end of the webbing
has been inserted through the split into the tube, I run hot metal into the tube, which
thus becomes a species of chill. The tube and webbing are now inseparably connected,
and when the process has been applied to both ends of the webbing, the latter, is
provided with cross-pieces more durable and more securely fixed than the wooden
ones, at a reduced cost. The ears by which the mattress thus made is hung to the
framework of a bedstead, may be fixed or formed on the chilled cross-bars in any
convenient manner, but preferably by being themselves chilled to the cross-bars, either
at the same time as the molten metal is poured into the tube, or separately. In the
first of these two cases I drill holes in the tubes, before the metal is poured into them,
exactly where the chill moulds for the ears are placed. When the metal is run into
the tube it passes through the holes and fills the chill moulds, so that only one pouring
is necessary in order to fill the tube and cast the ears upon it.
A modification of my invention, and one which, as it will ensure greater lightness
in the mattress, I shall probably often adopt, consists in chilling a tube of very small
diameter on each end of the webbing in the manner above described, and then
slipping the webbing down the split of the larger tube, so that the smaller tube may

page_text: be inside the larger. As the split in the larger tube is only just wide enough to almit
of the passage of the webbing, the smaller tube cannot be drawn out of the larger
through the split. Again, I may secure across the end of the webbing, in any manner
whatsoever a length of wire to take the place of the smaller tube just described. Or,
I may find it sufficient to merely bend or roll the edge of the webbing over till it
becomes thicker than the split in the tube, and then slip the webbing into the split so
that the bent or rolled edge of the webbing may be inside the tube. Or, I may grip
the end of the webbing between two chills forming together an open trough-shaped
chill, so that the end of the webbing enters slightly into this chill, and then run into
the latter a small quantity of metal: and when this is properly set, remove the chill
from the webbing, and slip the webbing into the split in the tube, as before, so that
the chilled metal may be inside the tube. Or, I may merely form a groove in the
wire webbing near the end of it, and then slip the split tubo on to the webbing in
such a manner that the edges of the split may enter the groove, gripping the webbing
there. In this instance the split in the tube will be rather less in size than the
thickness of the webbing where the groove is sunk, in order that, when the webbing
is forced into the tube, the latter may hold it with a certain amount of force. In all
these modifications, for the greater security of the webbing in the tube, I have
recourse to the following device. I make one end of each of the ears by which the
mattress is bung, in the shape of a clip. This clip which may be chilled or made of
wrought iron or steel, resembles a short piece of very strong tubing split along one
side, with an inner diameter slightly less than the outer diameter of the tube on the
webbing. One of these clips is forced on to the tube on the webbing from each end,
and causes the edges of the split in the tube to close tightly on the webbing. 1 then
chill ornamental pieces on each end of the tube, when the webbing cannot be drawn
from the tube, either through the split in the tube, or by reversing the process by
which it (the webbing) was first slipped into the tube.

page_text: 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 and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
My invention has for its object to supersede the usual method of mounting wire
wove spring mattresses, which is as follows. After a suitable length of wire webbing
out of which the mattress is to be made has been cut off, each end of it is tightly fixed
between two stout strips of wood, which are held together by screws.
Suitable ears
of wrought or cast iron are then screwed on to the wood strips, and by these ears the
mattress is hung upon the framework of the bedstead. According to my invention
the aforesaid strips of wood are dispensed with. In their place I use a wrought iron
tube having a longitudinal split extending along the whole of its length, of sufficient
width to admit of the insertion of the wire webbing. When the end of the webbing
has been inserted through the split into the tube, I run hot metal into the tube which
thus becomes a species of chill. The tube and webbing are now inseparably connected,
and when the process has been applied to both ends of the webbing, the latter is
provided with cross pieces more durable and more securely fixed than the wooden ones,
at a reduced cost. The cars by which the mattress thus made is hung to the frame-
work of a bedstead, may be fixed or formed on the chilled cross bars in any convenient
manner, but preferably by being themselves chilled to the cross bars, either at the
same time as the molten metal is poured into the tube, or separately. In the first of
these two cases I drill holes in the tubes, before the metal is poured into them, exactly
where the chill moulds for the ears are placed. When the metal is run into the tube
it passes thro' the holes and fills the chill moulds, so that only one pouring is necessary
in order to fill the tube and cast the cars upon it.
A modification of my invention, and one which, as it will ensure greater lightness
in the mattress, I shall probably often adopt, consists in chilling a tube of very small
diameter on each end of the webbing in the manner above described, and then
slipping the webbing down the split of the larger tube so that the smaller tube may
be inside the larger. As the split in the larger tube is only just wide enough to
admit of the passage of the webbing, the smaller tube cannot be drawn out of the
larger through the split. Again I may secure across the end of the webbing, in any
tnanner whatsoever, a length of wire to take the place of the smaller tube just
described. Or I may find it sufficient to merely bend or roll the edge of the webbing
over till it becomes thicker than the split in the tube, and then slip the webbing into
the split so that the bent or rolled edge of the webbing may be inside the tube. Or I
may grip the end of the webbing between two chills forming together an open trough-

page_text: shaped chill, so that the end of the webbing enters slightly into this chill, and then
run into the latter a small quantity of metal and, when this is properly set, slip the
webbing into the split in the tube as before, so that the chilled metal may be inside
the tube. Or I may merely form a groove in the wire webbing, near the end of it,
and then slip the split tube on to the webbing in such a manner that the edges of the
split may enter the groove, gripping the webbing there. In this instance the split in
the tube will be rather less in size than the thickness of the webbing where the groove
is sunk, in order that when the webbing is forced into the tube the latter may hold it
with a certain amount of force. In all these modifications for the greater security of
the webbing in the tubo I have recourse to the following device. I make one end of
each of the ears by which the mattress is hung, in the shape of a clip. This clip,
which may be chilled or made of wrought iron, steel, or malleable iron, resembles a
short piece of very strong tubing split along ono sido, with an inner diameter slightly
less than the outer diameter of the tube on the webbing. One of these clips is forced
on to the tube on the webbing from each end and causes the edges of the split in the
tube to close tightly on the webbing. I then chill ornamental pieces on each end of
the tube, when the webbing cannot be drawn from the tube either through the split
in the tube or by reversing the process by which it (the wobbing) was first slipped
into the tube.--
Having thus stated the-nature-of-my-invention I will now proceed_to_more_
particularly describe it-in-connection with the accompanying drawings. The same
letters of reference occurring upon the different figures indicate corresponding parts...
Figure 1 is a side elevation shewing the method in which I propose to mount wire
wove spring mattresses in order that they may be hung on the framework-of-bedsteads.-
In this figure A A are tubes having longitudinal splits extending along their whole
length cut in them as shewn to receive the ends of the length of webbing B (of which
only a portion appears in the drawing). According to tho first modification of my
invention, after the webbing B has been inserted into the tubes A A, I run hot metal
into the tubes. When this has cooled the webbing and tubes are inseparably fixed.
Cand Dare ears which I either chill on the tubes A A in any suitable manner, or
cast separately as clips, and drive on to the tubes A A. It will be seen on reference
to figure 1 and figures 2 and 3, which shew the clips C and D as they appear looking
in the direction of the arrows E and F, that the lower part of the clip C is formed of
a shape to enable it to be fixed into a suitable bracket on the framework of the
bedstead, while the lower part of the clip D has a screw passing through it, so that
when that end of the mattress is hung upon its bracket, by the turning of the screw
the mattress can be stretched to any desired degree. I usually place two of the clips Ü
or D, as the case may be, on each tube A A at a convenient distance from the ends of
the said tube, which project slightly beyond the edge of the mattress: but any number
may of course be employed.
Instead of filling the tubes A A with molten metal and thus chilling the webbing B
to them, I may prefer, for the sake of lightness, to chill on to the ends of the
webbing B tubes of a diameter only just larger than the splits in the tubes A A. The
webbing can then be slipped into the tubes A A in such a manner that the smaller
tubes shall be inside the larger. The smaller tubes being larger than the splits in the
tubes A A cannot then be drawn through the said splits. Or I may form on the ends
of the webbing B, in any manner whatsoever, to take the place of the small tubes
described, such an obstruction as shall prevent the webbing from being drawn from
the tubes A A when it has once been slipped therein. But the modification which at
present seems to me, both in point of lightness and of convenience, the best, is that
which I shall now describe. I cast the clips C and D separately from the tubes A A,
and make them with an inner diameter slightly smaller than the outer diameter of the
tubes A A. After the webbing has been slipped into the tubes A A, 1 force the
clips C and D on to the tubes AA (two or more on each). The inner diameter of
the clips being smaller than the outer diameter of the tubes, the latter are pinched in
by the clips, and in their turn pinch the webbing which is then securely fixed.

page_text: Figure 4 illustrates the ornamental chilled pieces which cast on the ends of the
tubes A A after the webbing is thoroughly secured by any of the aforesaid means into
the tubes, to give them a more finished appearance, and further secure the webbing.
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
I. The general arrangement of tubes A A, webbing B, and clips C and D,
substantially as herein described and illustrated by the accompanying drawings.
II. The use of the longitudinally split tubes A A, whether in conjunction with
chilled metal or not, for the purpose herein set forth and illustrated by the accom-
panying drawings.
III. The use of the clips C and D for the purpose herein set forth and illustrated by
the accompanying drawings.
IV. The use of the longitudinally split tubes A A, and clips C and D, conjointly,
for the purpose herein set forth and illustrated by the accompanying drawings.
V. The various methods herein described by which an obstruction is formed on
the ends of the webbing B to prevent its being drawn through the splits in the
tubes A A.
