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
to be as follows :—
.
Our said Invention has reference to improvements in the construction of mattress
frames and bedsteads which improvements are also applicable to camp beds,
ambulance stretchers and ships berths. The improved mattress frame is preferably
composed of two side tubular members which may be of ordinary iron tubing
connected together at each end by means of angle iron cross members so as to
compose a rectangular frame. To secure the said angle iron members to the ends
of the tubes, we employ studs which fit the interior of the tubes. The said studs
are formed with heads and are passed through holes in the angle irons into the
tubes the heads on the studs serving to confine the angle iron against the tube
ends. Bolts or keys are passed through both tubes and studs to prevent the studs
from moving or keys or tapered cottars might be driven in which would tend to
draw the studs into the tubes and thus cause them to hold the angle irons more
firmly against the ends of the tubes, thus increasing the rigidity of the frame.
Instead of the combination of tube and angle iron described the section of the
members may be varied so long as the described method of uniting them is
retained. In putting together the members of a bedstead the tubular sides enter
or butt against bosses formed on the pillars or uprights. The aforesaid studs are
inserted from the other side so as to enter the tubes and are secured therein by
bolts or keys. We may form the stud on the said boss or on the corner bracket.
If desired the said bedstead may comprise a mattress frame by causing the tubes
to pass through angle iron members a short distance from the pillars the said angle
irons being secured to the tubes by a pin, bolt or key. The mattress surface
applied to frames or bedsteads constructed in the aforesaid manner may be of any
suitable material, but is preferably of metallic woven or linked wire or chain or
laths stretched between the two ends and secured thereto by known or suitable
BOJ7

In mattress frames or camp or ambulance beds and ships berths we may
hinge head and foot rests on the frame which are preferably made capable of being
folded close to the frame but these rests may be dispensed with. To support the
frames at a suitable height from the ground or on a bedstead we apply folding
legs or supports to the tubular side members. These legs are hinged or pivotted
on the tube and the boss which embraces the tube is slit so as to admit a fixed pin
or pins projecting from the tube. When the legs are supporting the frame the
said pin occupies the slit so as to prevent the leg from turning on the tube but
when it is desired to fold the legs beneath the frame the boss is slid along the tube
until the slit clears the pin after which the leg may be turned on the tube. The
disposition of the pin and slit might be reversed. For ships berths and for
application to ordinary bedsteads we by preference use fixed feet instead of the
said folding legs. When the mattress frame is used as an ambulance bed we apply
fixed or removable handles to the angle iron ends. Frames constructed as herein
described are particularly suited for camp and ambulance beds as the hinged parts
can be readily folded up so as to render them capable of being packed together
into little space whilst their simplicity of construction and lightness render them
specially suited for transport.

page_text: Improvements in the Construction of Mattress Frames and
Bedsteads.
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 said Invention has reference to the construction of bedsteads and mattress
frames and is more particularly applicable to the production of the lighter classes
of bedsteads and mattress frames such for example as are used for camp, barrack,
and ambulance purposes or for ships berths and which can be folded together and
packed into small space-And in order that our said invention may be properly
understood we will now proceed more particularly to describe the same, reference
being had to the annexed two sheets of drawings and to the letters and figures
marked thereon, to be as follows :—
Fig. 1 of the accompanying drawings is a side elevation of a camp or barrack
bed constructed in accordance with our invention Fig. 2 being a plan of the same.
The frame is composed of the side members a. which are made of ordinary metal
tubing the two sides a. being connected at each end by angle iron bars b. so as to
form a parallelogramic frame. The method of uniting the angle bars b. to the ends
of the tubes a. is more clearly shown to an enlarged scale at Figs. 8 and 9 of the
drawings. In Fig. 8 the tube a. and angle iron b. are shown in section That part
of the angle iron which comes opposite to the end of the tube a. is pierced by a
hole of the same diameter as the interior of the tube and a stud c. is introduced
through the hole so as to enter the tube for a short distance. A rivit or pin d. or
it might be a bolt or screw is driven through both tube and stud so as to hold
them together the angle iron b. being thus firmly held between the end of the tube
and the head of the, stud c. This method of attachment is employed at each corner
of the frame shown at Figs. 1 and 2, and we thus obtain a light and secure
rectangular frame or bedstead. In Figs. 1 and 2 the frame is supported by fixed
legs which consist as shown of T couplings e. secured to the side tubes a.
lengths of tube f connect the couplings e with feet g. The frame may be supported
in an inclined position as shown or it may lie in a horizontal plane if desired.
The mattress surface which is applied to the herein before described frame may
consist of any known or suitable material but is preferably of metallic woven or
linked wire or chain or laths stretched between the two ends and secured thereto
by known or suitable means. In the example as shown at Fig. 2 we apply thin
metallic laths h. which are hooked or connected to the end angle bars by inter-
posed springs i. which give the necessary elasticity to the mattress surface formed
by the laths. To preserve the relation of the laths to each other and to the frame
Short

page_text: we employ links or hooks k. which connect the laths to each other and to the side
tubes If desired springs may also be employed in conjunction with these links k.
Fixed hinged or removable head and feet rests 1. may be applied to the frame.
The frame shown in Figs. 1 and 2 is not intended to fold together but we will now
proceed to describe a frame which may be folded together so as to occupy little space
when being transported from place to place. Figs. 3, 4, and 5, show such a frame
Fig. 3 being a side elevation of the frame when opened out for use while Figs. 4
and 5 are views of the frame folded together for storage or transport. As will be
seen the tubular sides a. and angle iron ends 6. are secured together in the manner
already described but the legs or supports m., are capable of being turned on the
side tubes so as to lie close to the mattress surface. We form a slot or groove in
each of the couplings e. which receive a fixed pin o. projecting from the tube a.
In fig. 3 this pin o. has entered the slot and prevents the coupling from turning on
the tube a thus keeping the legs in a vertical position. Pinching screws . are
employed as shown to still further secure the couplings in position. If it is desired
to fold the legs into the same plane as the mattress surface the pinching screws 2.
are loosened and the couplings are slid upon the tubes a until the slot in each has
cleared the pins o. when the leg may be turned into the position shown at Fig. 5.
A pin p. may be provided to prevent the leg coupling from sliding further than is
necessary. As a substitute for the pins o. to hold the legs in position we may
secure a separate stop o. to the tube as shown at Fig. 7a sheet 2 of the drawings
which stop o has two, three or more projecting fingers which enter corresponding
recesses in the coupling e and prevent the same from turning on the tube when
thrust in to gear with the stop o. By another modification the stop o. might be
formed as at Fig. 7b having a projection which enters a recess in the coupling e. so
as to prevent turning when the two parts are brought into interlocking contact as
shown at Fig. 7b. The head and foot rests l. are also hinged so as to be capable of
being turned into the position shown at Figs. 4 & 5. In the example the legs are
of equal length so that the frame lies parallel with the ground line but its position
might be inclined as in Fig. 1. Figs. 6 and 7 are views of a bed similar to those
already described but jointed in the middle so as to fold into half its length. The
tubes a. may be hinged together or connected by a stud or core » (fig. 7) the joint
being strengthened or secured by a sleeve 8. which can be slid back when it is
desired to fold the two halves of the frame together as shown at Fig. 7. The legs
and head and feet rests are folded as already described. In Figs. 10 and 11 the
well known dovetail for connecting the sides or frame to the uprights is formed on
the outer end of the connecting stud c. the dovetail and flange w. taking the place
of the stud head shown in Figs. 8 and 9. A flange t. may be formed on the
dovetail so as to mask the end of the angle iron b. and give it a solidity of
appearance from the side. Fig. 12 shows another method of connecting the frame 4
to the uprights The tube a. passes through the angle iron b. and butts against the
corner block u. of the upright pillar. A stud c. is passed through the block u and
into the end of the tube a. and a bolt d. passes through the tube a angle iron b.
and stud c thereby securing the whole of the parts together. A tapered key or
cottar might be used in place of the bolt d. to draw the parts more firmly together. 4
When a mattress frame constructed as herein before described is used as an
ambulance bed we apply fixed or removable handles to the angle iron ends or
the frame might be mounted on wheels and protected by an awning. It will be
evident that instead of having the sides of tubing and the ends of angle iron we
might make the sides of angle iron and the ends of tubing or we might make the 5
frame entirely of angle iron or entirely of tubing. For example in a frame made
entirely from tubing the tubes forming the ends might be forged or shaped at the
corners of the frame to an angle or other approximately suitable section which
would permit of union with the tubular sides in the manner described.
applying our invention to the construction of ships' berths the supports or legs 5
would be dispensed with or modified.
In

page_text: Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is.
1. Constructing bedsteads, mattress frames, ships berths and camp or barrack
and ambulance beds from combinations of angle iron and tubular members united
at the corners by the means more particularly described with reference to Figs. 8, 9,
10, 11 and 12 of the drawings.
2. Constructing bedsteads, mattress frames, camp and other beds from the
specified materials and connected in the manner described with supports, rests,
and other parts or members capable of being folded together so as to form a light
compact and portable bed substantially as herein before described and shown.
3. The method of forming and hinging the folding supports or legs of bedsteads
and frames of the described construction, substantially as set forth and indicated.
