I CHARLES WALKER TORR of the firm of Robert Walter Winfield and Company of
Cambridge Street Works Birmingham in the County of Warwick Merchants and
Manufacturers do hereby declare the nature of this Invention to be as follows :-
My invention has reference principally to metallic bedsteads cots and couches with
which spring mattresses are employed but may also be applied to bedsteads cots and
couches in which ordinary or lath mattresses or other seatings are employed.
I will describe my invention in connection with a metallic bedstead.
In metallic bedsteads having spring mattresses it is desirable that the side bars of
the bedstead frame should be situated at a lower level than the plane in which the
spring mattress is situated in order that when the spring mattress is depressed by a
person lying in the bed it may not strike against the sides of the bedstead frame and
the noise and shock which but for the depression in the bedstead frame would be
produced are avoided.
In the ordinary method of manufacturing the side bars of the bedstead frame the
ends of the tubes rods or angle bars forming the said frame are cast in the dovetail
blocks in the usual way the said ends being horizontal. At a short distance from the
dovetail blocks the said tubes rods or angle bars are cranked so as to depress the
greater part of the tube rod or bar to a lower level than the ends of the tube rod or
bar. This depressing of the sides of the bedstead frame involves two bendings of the
tube rod or bar near each end.
In making a bedstead for a spring mattress according to my invention I cast the
end of the tube rod or bar into the dovetail block but instead of making the said
block square I give to that face of it in which the tube rod or bar is cast an angular
position the said face being inclined at an angle of about forty degrees to a vertical
plane. By giving this inclination to the face of the dovetail block in which the tube
rod or bar is cast only one bending at each end of the tube rod or bar is required to
give the depression in the sides of the bedstead frame instead of the two bendings at
each end required in the ordinary method of manufacture and the depression sets in
directly from the dovetail block. The application of my invention to cots and couches
differs in no essential respect from its application to bedsteads as hereinbefore
described.

page_text: 1 CHARLES WALKER TORR of the firm of Robert Walter Winfield and Company
of Cambridge Street Works Birmingham in the County of Warwick, Merchants and
Manufacturers do hereby declare the nature of my 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 reference principally to metallic bedsteads cots and couches with
which spring mattresses are employed but may also be applied to bedsteads cots and
couches in which ordinary or lath mattresses or other seatings are employed.
I will describe my invention in connection with a metallic bedstead.
In metallic bedsteads having spring mattresses it is desirable that the side bars of
the bedstead frame should be situated at a lower level than the plane in which the
spring mattress is situated in order that when the spring mattress is depressed by a
person lying in the bed it may not strike against the sides of the bedstead frame and
the noise and shock which but for the depression in the bedstead frame would be
produced are avoided.
In the ordinary method of manufacturing the side bars of the bedstead frame the
ends of the tubes, rods or angle bars forming the said frame are cast in the dovetail
blocks in the usual way, the said ends being horizontal. At a short distance from the
dovetail blocks the said tubes rods or angle bars are cranked so as to depress the
greater part of the tube, rod or bar to a lower level than the ends of the tube, rod or
bar. This depressing of the sides of the bedstead frame involves two bendings of the
tube rod or bar near each end.
In making a bedstead for a spring mattress according to my invention I cast the
end of the tube, rod or bar into the dovetail block but instead of making the said
block square I give to that face of it in which the tube, rod or bar is cast an angular
position the said face being inclined at an angle of, say, thirty to forty five degrees to
a vertical plane. By giving this inclination to the face of the dovetail block in which
the tube, rod or bar is cast only one bending at each end of the tube, rod or bar is
required to give the depression in the sides of the bedstead frame instead of the two
bendings at each end required in the ordinary method of manufacture and the
depression sets in directly from the dovetail block.
Figure 1 of the accompanying Drawing represents in perspective the frame of a
metallic bedstead the junction of the side bars of the said frame with the dovetail
blocks being constructed according to my invention; Figure 2 represents in side
elevation and Figure 3 in plan a portion of one of the side bars of the frame and the
dovetail blocks at the ends of the side bar drawn to a larger scale.
The same letters of reference indicate the same parts in the several Figures of the
Drawing.
a, a are the side bars of the bedstead frame the said side bars being made of tubing
but solid rods or angle bars may be used in place of the tubing represented. The

page_text: greater part of each of the side bars a, a is situated at a lower level than the ends a², a
which are bent or curved upwards; b, b are the dovetail blocks at the head end of the
bedstead frame and c, c are the dovetail blocks at the foot end of the bedstead frame.
The socket parts d, d of the dovetail blocks, which are cast upon the bent or curved
ends a³, a of the side bars a, a, have the angular position represented instead of being
situated horizontally or at right angles to the vertical face of the dovetail block as
usual; that is, the part or socket d of each dovetail block in which the end of the side
bar a is cast is inclined at an angle of say thirty to forty five degrees to a vertical
plane. By giving the tubular sockets or parts d, d of the dovetail blocks the angular
position or inclination represented, or substantially the inclination represented, only
one bending a' at each end of the sides a of the bedstead frame is necessary to give
the required depression in the bedstead frame for the purpose hereinbefore explained
and the said depression sets in directly from the dovetail block as represented in the
drawing.
The bedstead frame represented is especially fitted for use with a tension or adjustable
spring mattress in which the tightening is effected by screws or other tightening
appliances. In order to facilitate the tightening of the mattress at the head end of the
bedstead I extend the dovetail blocks at the said head end towards the foot end of
the bedstead, the flat upper extended faces of the said blocks constituting bearing parts
for the tightening bar of the adjustable tension mattress to travel upon in tightening
the said mattress. When an ordinary spring mattress is employed both ends of the
bedstead frame may be furnished with short dovetail blocks of the kind represented at
the foot end of the bedstead.
The application of my invention to cots and couches differs in no essential respect
from its application to a bedstead as herein before described and illustrated in the
accompanying Drawing.
Having now particularly described and ascertained the nature of my invention and
the manner in which the same is to be performed I declare that I claim as my invention
of Improvements in the frames of metallic bedsteads cots and couches of the kind
hereinbefore described :-
Producing the required depression in the side bars of the frame of the bedstead,
cot or couch by giving to those parts of the dovetail blocks in which the ends of the
side bars are cast an angular position substantially as described and illustrated, whereby
only one bending at each end of the side bar is required to give the depression in the
side of the frame, the said depression setting in directly from the dovetail blocks as
herein before described and illustrated in the accompanying Drawing.
