Improvements in the Manufacture of Metallic Bedsteads.
I, SAMUEL ILSLEY WHITFIELD of 96 Sampson Road Sparkbrook in the
County of Warwick Bedstead Manufacturer do hereby declare the nature of this
invention to be as follows:-
The first part of my invention refers to the manufacture of such bedsteads as are
commonly called "combination spring bedsteads" and applies more particularly
to those made and finished with spring fabrics or meshes of lath or wire and spiral
springs without tension screws, the springs being at each extremity of the wire or
lath work and which springs are usually hooked into holes in the transverse end
bars of the bedstead, which are drilled and suitably arranged for the purpose.
By means of my invention I am enabled to convert ordinary lath bottom bedsteads
into combination spring bedsteads as follows, instead of hooking the springs or links
into the transverse end bars of the bedstead, 1 attach by suitably shaped hooks
screws or other means false bars to the ordinary end bars, these false bars being
drilled for the reception of the springs or links, when it is desired to attach the sides
of the spring mesh to existing side angle irons of an ordinary lath bottom
bedstead.
I use the ordinary lath studs or rivets and fasten to them hooks of wire or
flat-iron or steel suitably shaped to hold the side wires of the spring mesh in
position.
The second part of my invention refers to combination spring bedsteads or
spring mattresses with the kind of spring fabrics or meshes as described above and
has for its object the removal or suspension at will of the elasticity of such spring
work when required for such purposes as surgical operations. I bring about
this result. by fastening the spiral springs of the fabric or mesh in such a
manner that they remain rigid being prevented from stretching the other lath or
wire part of the mesh having no elasticity in itself the bed becomes perfectly
rigid until the springs are again unfastened. The springs are secured or fastened
up by means of bars of iron or other suitable material fixed across the ends of
them or by screw nuts, hooks or other convenient means and so arranged that
they may with facility be fastened or unfastened as may be desired.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Metallic Bedsteads.
I, SAMUEL ILSLEY WHITFIELD, of 96, Sampson Road Sparkbrook in the
County of Warwick, Bedstead Manufacturer, 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, reference being had to
the drawings hereunto annexed, and to the figures and letters shewn thereon:-
The first part of my invention refers to the manufacture of such bedsteads as are
commonly called "combination spring bedsteads," and applies more particularly to
those made & finished with spring fabrics or meshes of lath or wire and spiral
springs without tension screws, the springs being at each extremity of the wire or
lath work, and which springs are usually hooked into holes in the transverse end
.מ

arranged for the purpose.
My invention relates to means whereby I am enabled to convert ordinary lath
bottom bedsteads into combination spring bedsteads.
In the accompanying drawings, in which similar letters of reference relate to
similar parts.
Figure 1. is a view of a spring mattress with my improvements attached
thereto..
Figure 2. is a side angle iron with studs thereon.
Figure 3. is an alternative method of forming the false bar.
Figure 4. a further alternative.
. Figure 5 & 5 an alternative hook arrangement.
Figure 6. alternative method of attaching false bar to a horizontal rod instead
of an angle bar.
. Figure 7. is a full sized view of a metal book forming part of my improvements.
Figure 8. the same when fitted over the studs.
Figure 9. a view of a side bar of a bedstead having the hooks rigidly attached
thereto by means of rivets or otherwise.
Figures 10. 11. & 12. shew views of the second part of my invention.
Instead of hooking the spiral springs or links directly into the transverse end
bars of the head and foot of the bedstead, I attach false bars A, which are
drilled for the reception of the springs or links, to the ordinary end angle bars.
These false bars A may be connected to the end bars in several ways either
by means of suitably shaped hooks B, as seen in Figure 1, which hook on to
the angle bars, & impinge the same, or the false bars may be slotted out to fit
round the upright standards of the bedsteads as seen at C. Figure 4.
more the false bars may be made of angular form as shewn at Fig. 3, whereby
a. very firm bearing is afforded, and an increase of strength produced, when the
same is connected by the hooks B to the angle bars.
Further-
In the above described forms of false bars, when attached to the frame they
would rest upon the studs, over which, as a rule, the eyes of the laths pass.
I may, however, drill the false bars, when desired for them, to fit over the
studs which will form a very effective means for attaching the false bars to the
ordinary bars, as I can then dispense with the hooks, B.
I will proceed to describe a method for attaching the sides of the spring
mesh to existing side angle irons of an ordinary lath bottom bedstead. One
form is this: I make use of the ordinary lath studs or rivets E, and pass
over same hooks of wire or suitable flat metal F; when flat metal is used the
one end is drilled with eyes G to fit over the said studs E, which may then be
turned round in the usual manner, the. other end forms a hook as shewn, which
hooks on to wire fabric H.
These wire or flat metal hooks are suitably shaped to securely hold the side
wires of the spring mesh in position.
As a modification of the above method, I may when preferred, and in order
to meet requirements permanently attach the wire or flat inetal hooks by rivetting
or otherwise to the side angle irons of the bedstead. See Figure 9.
I anay sometimes connect or attach the wire or flat metal hooks or clips to
the wooden frame of a mattress.
By these improvements ordinary bedsteads and cots may be fitted with a spring
mesh in lieu of the laths and stretcher, as no alteration need be made in the
construction of the bedstead.
The second part of my invention refers to combination spring bedsteads or
spring mattresses, having the kind of spring fabrics or meshes as described above,
and has for its object the removal or suspension at will of the elasticity or
springy nature of such spring work when required for such purposes as surgical
operations when a rigid bed bottom is necessary. To effect the object that I have
in view, I fasten the spiral springs of the fabric or mesh composing the bedstead

page_text: bottom or mattress in such a manner that they remain rigid, being prevented
from acting or stretching, the other lath portion or wire part of the mesh having no
elasticity in itself, the bed becomes perfectly rigid until the springs are unfastened.
The springs may be secured or fastened up, by means of two bars or laths of
iron or other suitable material, II. H¹ Figure 10 which are fixed transversely
across the ends of the springs I, and bearing against the same keep them rigid the
bars are bolted together as at J or a bar K Figure 11 may be passed through
rings L' on the springs I or the springs I may be fastened by screws, & nuts M
Figure 12 or hooks, or other convenient means for the purpose, & so arranged,
that such springs may be with facility fastened or unfastened as may be
desired.
By the use of this second part of my invention a very effective and useful
addition is provided for bedsteads and cots which will be found of eminent
advantage in the hospital or sick room.
I wish it to be understood that I do not limit myself to the more precise details
of construction as regards the first or second part of my invention, as I may vary
the different features of same without in any way materially departing from the
main principles of my said invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
clain is,
Firstly. In the manufacture of metallic bedsteads, the combination and arrange-
ment of and, improved method of attaching wire spring mesh or links to existing
lath bottom bedsteads by means of the arrangements of false bars A shewn in the
various forms, which false bars carry the wire spring fabric, and may be
attached to the ordinary angle bars of the bedstead by hooks B or other convenient
means, substantially as herein, more fully set forth and described.
Secondly. In the manufacture of metallic bedsteads, the particular formation and
arrangement, alone or in combination with the other parts of the bedstead, of the
metallic hooks or clips F so formed as to hook on to the sides of the spring
fabric, said hooks or clips F being made in either of the forms as herein shewn, or
the equivalent thereof, for the purpose substantially as herein set forth and
described.
Thirdly. In the manufacture of metallic bedsteads the particular formation
arrangement and construction of the parts constituting the improvements in the
second part of my invention as herein set forth, whereby the spring bedstead or
mattress may be suitably adjusted when required for surgical operations, or such
like, substantially as herein described.
Fourthly. I claim the general improvements alone or in combination in the
manufacture of metallic bedsteads herein set forth.
