Improvements in the Construction of Woven Wire and other Spring
Mattress Frames.
I.
I, THOMAS KENDRICK of Summer Lane Birmingham in the County of
Warwick 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 accompanying drawings
and to the letters and figures marked thereon
My invention consists of an improved method of constructing wire woven or other
spring mattress frames as applied to metallic bedsteads, cots, couches, and such like
articles. Hitherto in attaching spring mattresses to metallic bedsteads it has been..
usual to employ screw pins either in conjunction with iron clips fitting upon. the
angle iron or the tube end bars of the bed frame or passing through the said end bars,
for the purpose of drawing the mattress up to the required tension.
This contrivance necessarily leaves a certain space between the end pieces of the
spring mattress and the rails of the bedstead, thereby diminishing the elastic surface
of the mattress, and by leaving a gap imperfectly supporting the bedding at those."
parts.
.
A further objection to the methods generally in use has been found in the fact of
the threads of the screw pins stripping and the clips breaking and the long screw pins.
boing liable to injure the bedding..
:
The object therefore of my invention is to construct an improved frame, consisting
partly of iron and partly of wood to which the spring mattress is permanently attached
which by dispensing with adjusting screws, clips and similar contrivances effectually.
reinoves the objections above alluded to, ensures a more perfect elastic surface and
admits of greater simplicity of construction. The mattress frame is fitted with
dovetails or other connections upon its corners for the purpose of attaching the same
to the corner blocks upon the pillars of a metallic bedstead thus forming a complete
bed bottom.
.
I will now describe my invention as applied first to mattress frames in
which angle iron or tube is employed for the sides only and in the second place" (LS
applied to frames cast or otherwise constructed in one piece, forming a bed bottom
having also angle iron or tube ends: In constructing an improved mattress frame
according to the first part of my invention, I cast upon the ends of the angle iron or
tube sides dovetail blocks having receptacles or shoe brackets upon their inner sides
as shewn in Figs. 1, 2 and 3; at (A) into which I fit the wood end pieces of the
mattress which are secured by means of screws pins and nuts. By this means the

perfect elastic bed bottom.
By using material of the best quality in the production of the spring mattress
which is not liable to stretch or become loose by use, I am enabled when fitting the
end pieces into the shoe brackets or receptacles described above to pull the mattress
up to the required tension and so dispense with all adjusting or tightening
appliances.
In the second part of my invention I employ a complete angle iron or tube
frame or bed bottom as shewn in Figs. 5 and 6.
I attach the wire wove or other spring mattress to wooden end pieces as before,
which I stretch upon the iron frame and permanently affix to the same by means of
pins passing through the said end pieces and the angle or tube end bars and secured on
the underside by nuts as in Fig. 6.
Where the frame is constructed of tube 1 cast upon the end bars chills having flat
upper surfaces upon which the end pieces of the mattress may take their bearings in
which I cast screws which pass through the said end pieces the same being secured
by nuts.
In this method as in that previously described I dispense with tightening or
adjusting screws clips and similar appliances the mattress being stretched upon the
frame permanently at its proper tension and not being liable to become slack from
use.
Figs. 1 and 2 are respectively plan and elevation of the dovetail block with shoe
bracket (a) shewing the wood end piece of the mattress attached as first herein
described.
Fig. 3 is a sectional view of the same from the back.
Fig. 4 is a perspective view of a method of connecting the sides of the mattress
frame to the pillars of a metallic bedstead in which the ordinary dovetail is super-
seded by an entirely new arrangement of meeting surfaces secured by nut and bolt
the wooden end piece being attached in the same way as in Figs. 1, 2 and 3.
Fig. 5 is a perspective view of a wire woven spring mattress stretched upon an
angle iron frame in accordance with the second part of my invention and Fig. 6 is
a view of a portion of the underside of same shewing method of attaching.
Figs. 7 and 8 are respectively side and end elevations shewing a tube frame, the
mattress ends being supported in part by chills cast upon the tube ends as previously
referred to.
The connection of the frame with the pillar in this instance consists of a cone
shaped plug fitting into the corner block and secured by a nut which may be recessed
into the said corner if required. The methods of connection described under Fig. 4
and Figs. 7 and 8 may be applied, either to the first or second part of my invention
interchangeably.
I wish it to be understood that I do not confine myself to the precise form of
bracket as shewn in the accompanying drawings or of any other portion for the mattress
or frame, reserving to myself the right to construct the same in any form or manner
consistent with the principles of this invention.
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 construction of mattress frames or bed bottoms upon an improved principle by
applying wooden end pieces in conjunction with angle iron or tube sides or with frames
for the purposes and the manner herein set forth and specified.
