Improvements in Portable Metallic Mattresses.
We ISAAC CHORLTON of Blackfriars Street, Manchester; in the County of Lan
caster, Spring Mattress Manufacturer, and GEORGE LAMB SCOTT also of Manchester,
aforesaid, Engineer, do hereby declare the nature of the said Invention to be as
follows:-
Our Invention relates to the so termed metallic mattresses which have yielding
surfaces composed of woven wire or of combinations of chains and springs or
otherwise constructed to have yielding reticulated metallic surfaces as is now well
understood.
In some cases these mattresses are not in themselves provided with rectangular
frames but have end bars or rails which are designed to be attached to bedstead
frames means being provided for imparting a suitable tension to the mattress surface.
Owing to variations in the proportions and formation of the ends of the bedstead
such mattresses as ordinarily constructed are not capable of being readily fixed to all
patterns of bedstead. The object of our Invention is to render the connections of the
mattress bars with the bedstead frame more adjustable. We form the end bars so
that the holding clips can be fixed in any required positions upon each bar or we
attach grooved pieces to the bar and form the clips to interlock with such pieces and
to be capable of being shifted in the direction of the length of the bar to avoid
uprights upon the end framing of the bedstead or for other reasons.
In
When arranging for the clips to take hold of any part in the length of the bar we
roll or form the bar with a raised edge or square beading on its upper surface.
the cases wherein tightening screws or holding bolts pass through the vertical
members of a bar we form slots in the bar and provide long nuts washers or plates on
one side of the said member the bolts or screws passing through such nuts washers or
plates or we attach strengthening plates bars or parts to the bar to compensate for the
reduction in strength arising from the formation of the slots. In some cases we may
arrange for the holding clips to engage with slots in the bar or in each bar.

page_text: To provide for varying proportions in the angle iron or metal end rails of bedsteads
we make the connecting clips adjustable--that is to say we form each clip in two
paris one part being adjustable in or upon the other so that the clip will fit rails
varying in respect of the width of the vertical member of the angle rail. The paris
when adjusted may be secured by means of screws or of pins or by other suitable
means. To prevent the end rails to which the mattress is attached from canting, we
secure angle pieces to the outer ends of the said rails the vertical webs of the angle
pieces resting on the side rails or members of the bedstead.
To provide for varying conditions the vertical webs of the angle pieces may be
made adjustable in depth or we may form the angle pieces with bosses or studs into
or upon which we may screw pins or nuts which bear upon the side rails and can be
set to any required depth.

Improvements in Portable Metallic Mattresses.
We ISAAC CHORLTON of Blackfriars Street, Manchester, in the County of Lancaster,
Spring Mattress Manufacturer, and GEORGE LAMB SCOTT also of Manchester aforesaid,
Engineer, 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 and accompanying drawings:-
:-
Our Invention relates to the so termed. metallic mattresses which have yielding
surfaces composed of woven wire or of combinations of chains and springs or otherwise
constructed to have yielding reticulated metallic surfaces as is now well understood.
In some cases these mattresses are not in themselves provided with rectangular frames
but have end bars or rails which are designed to be attached to bedstead frames
means being provided for imparting a suitable tension to the mattress surface.
Owing to variations in the proportions and formation of the ends of the bedstead such
mattresses as ordinarily constructed are not capable of being readily fixed to all
patterns of bedstead. The object of our Invention is to render the connections of the
inattress bars with the bedstead frame more adjustable and this we accomplish by
making the said connections adjustable sideways.
Our invention will be clearly understood when the same is described with reference
to the accompanying sheet of drawings wherein Fig. 1 represents the upper portion

page_text: of one end of an ordinary metal bedstead and is provided to illustrate the principal
object of our invention. In the said Fig. a a represent two clips which engage with
the end rail of the bedstead and serve to connect one end of a mattress with the
bedstead. In ordinary practice these clips would be attached at fixed points to the
said mattress and when the mattress would have to be secured to the bedstead the
uprights ce might be in the way, in which case inconvenience and loss of time would
be occasioned. Figs. 2 and 3 illustrate the method whereby we obviate this incon-
venience. In the said Figs. a is one of the two clips which engage with the bedstead
rail so as to resist the strain of the mattress as clearly shown in Fig. 2. This clip
can be applied to the rail in any suitable position. One of the end bars of a mattress
represented by d. The said bar is rolled or formed with a raised edge or beading
as shown and the connecting screw bolt e is formed with a slotted head the slot being
shaped to take hold of the said raised edge as clearly indicated so that the mattress
can be strained to the required extent by tightening a nut upon the said bolt. It
will be seen that the head of the said bolt can be shifted along the bar d into any.
required position being adjustable sideways along the said bar in the same manner as
the clip is adjustable along the, rail so that the parts cc or any other parts of the
bedstead end can be avoided and the connections of the mattress with the bedstead be
applied in the positions most suitable to each pattern of bedstead.. Fig. 4 illustrates
the direct application of the clip to the bar without the intervention of the tightening
bolt e. In some cases this form of clip would be used at one end of the bedstead. and
the connections illustrated by Figs. 2 and 3 at the other end. Fig. 5 illustrates one
of the modifications which we may make in the connection. In this example the end
bar d of the mattress consists of angle iron or steel and to the vertical member of the
bar is attached a har d' of H section. The clip a is formed with a slot to interlock
with the bar d so that the said clip takes a firm hold of the bar at the same time that
it can be slipped sideways into any required position for the purpose of our invention.
This Fig. also illustrates a method whereby we make any of the clips adjustable to
provide for varying proportions in the angle iron or metal end rails of the bedstead.
The clip is formed in two parts a and a the latter being adjustable upon the vertical
member of the former and being shaped to hook inside the lower edge of the vertical
member of the rail. The clip is applied to the rail and the part a' moved upward
until it bears against the bottom edge of the said rail when the said part is secured by
means of the set screw for if preferred by means of a bolt. In Fig. 5* the foot is
cast on the clip and the adjustment effected by the screw i. Fig. 6 illustrates another
method of making the clips a adjustable sideways in the cases wherein the bars bare
made of angle metal. In the example long slots yg are formed in the vertical
member of the bar and slotted strengthening plates hh are riveted or secured to the
same part to compensate for the reduction in strength arising from the formation of
the slots. The straining bolts are passed through the said slots and can be shifted
sideways therein for the purposes of our invention. In some cases we may arrange
for the holding clips a to engage with slots formed in the bar d. Figs. 7 and 8
illustrate the method we adopt in cases wherein the bars d are made of wood. In
such cases we form slots in the bar and secure slotted metal strengthening plates h
thereto the bolts e passing through the bar and also through the slots in the said
plates. We may screw bolt or secure a metal bar to the outer side of the wood bar b
the said metal bar being adapted to engage with the holding clips.
For this purpose
a similar bar to the one represented by din Fig. 5 would be suitable.
In some cases
the end bars of the mattress by yielding to the strain become inclined upon their upper
surfaces. To prevent this we provide an adjustable prop or support at each end of
the bar such props taking a bearing upon the side rails of the bedstead. Fig. 9
illustrates the method of application of such props to an end bar d of a mattress.
this example a fixing is secured at or near each end of the bar the said fixing being
formed with a boss or pap which is drilled and tapped to receive a screw k. The screw
can be turned so as to lengthen or shorten the prop as required to prevent the
deflection of the bar.
In
