AN ADJUSTABLE SPRING MATTRESS
Year: 1884

page_text: I JOHN HUBBERT of 184 and 186 Old Street, St. Lukes in the County of Middlesex,
Bedding Manufacturer do hereby declare the nature of my said Invention for
AN ADJUSTABLE SPRING MATTRESS, to be as follows:-
The object of my invention is to construct spring mattresses in such a manner
that they may be readily and conveniently folded up for removal and transportation,
and also capable of adjustment for raising the head thereof while in usc.
I form such mattresses in three parts, which are hinged together at the sides
and provided with straps and buckles, so as to enable them to be folded up and
packed in a small compass.
When laid on a bedstead the mattress is simply unfolded and laid flat. But the
portion which lies under the head is fitted (in addition to the hinges) with two
segmental racks, having notches formed therein which take into suitable staples,
whereby the head portion of the mattress can be raised to any suitable inclination
for the convenience of the occupant.

Middlesex Bedding manufacturer do hereby declare the naturo of my said
Invention for AN ADJUSTABLE SPRING MATTRESS and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :—
The object of my invention is to construct spring mattresses in such a manner
that they may be readily and conveniently folded up for removal and transportation,
and also capable of adjustment for raising the head thereof while in use.
I form such mattresses in three parts which are hinged together at the sides and
provided with straps and buckles so as to enable them to be folded up and packed 1
in a small compass.
When laid on a bedstead the mattress is simply unfolded and laid flat. But tho
portion which lies under the head is fitted (in addition to the hinges) with two
Begmental racks having notches formed therein which fit into suitable staples
whereby the head portion of the mattress can be raised to any suitable inclination
for the convenience of the occupant. Such racks may also be applied to the foot
for invalids, if required.
- And in order that my said invention may be particularly described and
ascertained, reference is hereby made to the accompanying, drawings, in which
similar letters of reference indicate corresponding parts.
Fig 1. is a perspective view of a mattress mado. in accordance with my
invention.
Fig: 2 is a similar view with the head portion raised. Fig 3 is a similar view
of the same folded and Fig: 4 is an enlarged view of one of the joints with the
rack for raising the head.
The mattress a a is hinged at b b.-c is the segmental rack, the ratchet teeth of
which take into and abut against the box staple d. In some cases I apply a
spring in d to keep the rack in gear. c is a plate to which the rack is fixed by
the pivot Straps g g are attached to the two end pieces for use in packing up,
as shewn in Fig 3. These straps may be placed at the sides, or in any other
desired position.
A pin his attached by a short chain to the plate e for the purpose of raising the
rack c, and holding it out of gear, when shifting the head, by inserting the pin h
in the hole i.
The mattress is usually made with ordinary hour glass springs, but I do not
confine myself to any particular kind of springs or method of stuffing.
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:
1. The manufacture and use of adjustable spring mattresses composed of three
parts hinged together and capable of being folded up into a small compass,
substantially as described and shewn on the drawings.
2. In the construction of the aforesaid adjustable folding spring mattresses, the
application and use of segmental racks c c, arranged and operating substantially
as described and shown on the drawings.

page_text: 3. In the construction of adjustable spring mattresses, of the description
aforesaid, the application and uso of the straps g g substantially as and for the
purpose hereinbefore described and shewn on the drawings.
.
4. The general combination and arrangement of the several and respective parts,
together forming my invention of an adjustable spring mattress substantially as
hereinbefore described and shewn on the drawings.
