I, ISAAC CHORLTON, of 17, Blackfriars Street, Manchester, in the County of
Lancaster, Spring Mattress Manufacturer, do hereby declare the nature of this
invention to be as follows:-
My said invention has reference to metallic bed frames and bedsteads and
has for its object to more securely connect together the side rails to the end
uprights and also to provide means whereby the ends of the bedstead may be
readily adjusted at right angles with the side members.
In carrying my invention into effect I may use the means of connecting
together the ends and sides of the bedstead described in the Specification of
Letters Patent No. 21 of 1887 obtained by myself in conjunction with George
Lamb Scott. In addition to these means, I provide a bolt screwed with a right
and left hand thread and carrying a nut at each end. These nuts are embedded
in recesses formed within the top of the brackets carried by the side members
and end uprights which are secured together as described in the said former
specification.
"
The screwed bolt and nuts therefore form an additional connection between
the two brackets whereby they are better able to resist bending strain. To
adjust the two brackets to obtain a perfect right angle between the end and
side members I hollow out the brackets so as to expose the central portion of
the right and left hand screwed bolt. This central portion is formed with flat
faces to receive a suitable key or with holes for a pin or tommy," so that the
bolt can be revolved. By this action the end nuts thrust apart or bring together
the upper portion of the brackets so that the end members can be readily fixed
in a truly vertical position. As a modification I might employ a right and
left hand or other screwed bolt which would drop in recesses or a recess formed
in and engage the brackets or blocks carried by the side members and end
uprights so that upon operation of the bolt the parts would be adjusted.
Instead of using the means shown in the said former specification I may dis-
pense with them and secure the two brackets together by a duplicate of the
arrangements above described the bolts with right and left hand screw threads
being arranged at the top and bottom of the brackets. Or I might provide
the bottom of the corner bracket on the end member with a bolt, the bolt pass-
ing through a hole or slot in the other bracket and being secured thereto by
means of a nut. In another form the corner bracket could be provided or
formed with a recessed nut to engage with a screwed bolt carried by the other
bracket. It will be understood that both these last mentioned arrangements
are used in conjunction with the adjusting and securing bolt formed with a
right and left hand screw thread. As an additional security one of the
brackets may be formed with a recessed ledge to fit a corresponding projection
on the other bracket.
By connecting the brackets carried by the side members at two points as

page_text: herein described I am enabled to employ a larger diameter of tube for such
side members.
The brackets may be formed with rounded corners and sides so as not to
present sharp angles liable to inflict injury upon patients when used in asylums,
hospitals, and similar institutions.

Improvements in or connected with Bed Frames and Bedsteads.
I, ISAAC CHORLTON, of 17, Blackfriars Street, Manchester, in the County of
Lancaster, Spring Mattress 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 and accompanying
drawings:-
My said invention has reference to metallic bed frames and bedsteads and
has for its object to more securely connect together the side rails to the end
uprights and also to provide means whereby the ends of the bedstead may be
readily adjusted at right angles with the side members.
The accompanying sheet of drawings illustrate my invention.
Fig. 1 shows my invention in elevation applied to the corner blocks of a
bedstead.
Fig. 2 is a plan thereof and the remaining figs. show modifications of my
invention.
In carrying my invention into effect I may use the means of connecting
together the ends and sides of the bedstead described in the Specification of
Letters Patent No. 21 of 1887 obtained by myself in conjunction with George
Lamb Scott to which specification I refer the reader. In addition to these
means I provide a bolt a screwed with a right and left hand thread and carry-
ing a nut bat each end. These nuts are embedded in recesses formed within
the top of the brackets or corner blocks ed carried by the side members e¹ and
end uprights d which are secured together as described in the said former
specification.
The screwed bolt a and nuts therefore form an additional connection
between the two brackets ed whereby they are better able to resist bending
strain. To adjust the two brackets to obtain a perfect right angle between the
end and side members I hollow out the brackets so as to expose the central
portion of the right and left hand screwed bolt. This central portion is formed
with a boss a provided with holes for a pin or tommy" so that the bolt
can be revolved. Instead of the perforated boss a¹ the screwed bolt might be
provided with flat faces to receive a suitable key. By revolving the bolt a the
end nuts thrust apart or bring together the upper portion of the brackets cd
so that the end members can be readily fixed in a truly vertical position. The
top of the brackets cd may be provided with a plate to shroud the screwed bolt
and nuts.
In Fig. I show a modification of my invention.
In this case a single screwed bolt a is carried by the brackets which is
tapped to receive it and the perforated round head 6 of the bolt drops into a
recess formed in the bracket d.

page_text: In Fig. I show another modification of the screwed adjusting bolt a and
the method of applying same. A single screwed bolt a with perforated
head a¹ and nut 6 is dropped in suitable recesses formed in the brackets cd.
Instead of using the screwed bolt c and nut e shown in the said former speci-
fication I may dispense with them and secure the two brackets together by a
duplicate of the arrangement above described the bolts with right and left hand
screw threads being arranged at the top and bottom of the brackets. This is
shown in Figs. 4 and 5, Fig. 5 being an under plan view of Fig. 4. To pre-
vent the screw bolt a from dropping out one end of it is screwed into the
bracket d instead of being provided with a nut. The upper screwed bolt and
nuts are not shown in these figs. as they are exactly as illustrated in Figs. 1
and 2. Or I might provide the bottom of the inner bracket d on the end
member with a bolt y carried in a recess formed in the side of the bracket the
bolt g passing through a hole or slot in the other bracket c and being secured
thereto by means of a nut has shown in Fig. 7. In another form shown in
Fig. 8 the corner brackets d could be provided or formed with a recessed nut i
to engage with a screwed bolt j carried by the other bracket c. It will be
understood that both these last mentioned arrangements are used in conjunction
with the adjusting and securing screwed bolt a. As an additional security one
of the brackets may be formed with a recessed ledge to fit a corresponding pro-
jection on the other bracket.
By connecting the brackets carried by the side members at two points as
herein described I am enabled to employ a larger diameter of tube for such
side members.
The brackets may be formed with rounded corners and sides so as not to
present sharp angles liable to inflict injury upon patients when used in asylums,
hospitals, and similar institutions.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed 1 declare that what
1 claim is:-
1) As means for adjusting the end uprights of a bedstead at a right angles
with the side members the provision of a screwed bolt provided with a head or
a nut or nuts and means to operate the bolt to thrust apart or bring together
the top of the brackets carrying the end and side members substantially as
described and shown.
2) As means for connecting together and adjusting the tubular sides and
angle iron end members of a bedstead the combination with the brackets cd
bolted together and formed with projections engaging with corresponding
recesses, of a right and left hand screwed bolt provided with nuts and means
for rotating the bolt substantially as described and illustrated in Figs. 1 and 2
of the drawings.
3) The modified methods of connecting together and adjusting the tubular
sides and angle iron end members of a bedstead substantially as described and
illustrated with reference to Figs. 3 to 6 of the drawings.
4) As means for connecting together and adjusting the tubular sides and
angle iron end members of a bedstead the combination with the brackets carry-
ing the side and end members formed with projections engaging with recesses,
of a screwed top bolt provided with adjusting means, and removable bottom
bolts substantially as described and illustrated in Figs. 7 and 8 of the drawings.
Dated this 2nd of March 1900.
